Definitions
- the present invention relates to a planting device for root crops, in particular a root crop planting device, preferably designed as a potato planting machine, with a storage container for propagation crops to be planted and at least one planting wheel which is mounted in a frame of the planting device so as to be rotatable about a central axis, wherein the planting wheel has receptacles for propagation crops arranged one behind the other in its circumferential direction, and with a drive device for driving the planting wheel.
- a planting device for root crops in particular a root crop planting device, preferably designed as a potato planting machine, with a storage container for propagation crops to be planted and at least one planting wheel which is mounted in a frame of the planting device so as to be rotatable about a central axis, wherein the planting wheel has receptacles for propagation crops arranged one behind the other in its circumferential direction, and with a drive device for driving the planting wheel.
- Planting devices for root crops in particular root crop planting devices, have been known for a long time, for example from GB 241664 A or DE 22 00 562 A1.
- the object of the present invention is to treat the propagation crops, in particular potato tubers, more gently during the laying process and to lay them more precisely.
- the receptacles each have a receiving opening for feeding an isolated propagation crop into the receptacle.
- a receiving opening for feeding an isolated propagation crop into the receptacle.
- the singling and dispensing process can be better controlled.
- the size of the receiving opening can be adjusted to the propagation crops that are typically to be distributed before the laying wheel is installed, so that double occupancy of the receptacle with more than one propagation crop is avoided.
- the receiving opening is offset from an outer circumference of the laying wheel, which is defined by its greatest radial extent, in the direction of the axis of rotation. This allows the propagation fruits to be separated to be picked up closer to the axis and thus at a lower relative speed before they are accelerated to the discharge speed.
- the potatoes can therefore be treated more gently, which is particularly advantageous for planting material that has already formed germs.
- the holders have the respective holder opening on their side facing the central axis.
- the separation of the propagation fruits can therefore take place even closer to a central axis, which corresponds to the axis of rotation of the laying wheel during operation.
- the holder opening is thus formed on an inner side of the holder with respect to the central axis.
- This inner side can be formed, for example, by an annular frame element of the laying wheel, in which the respective receiving opening is arranged.
- the separated potato tuber In comparison with a radially further outward separation and transfer of the propagation fruits into the holder, in this embodiment of the invention the separated potato tuber must be accelerated to a lower speed for the transfer to the respective holder of the laying wheel rotating about the central axis.
- the impulse acting on the propagation fruits for transfer to the holder is reduced, which leads to gentler treatment of the potatoes.
- the potatoes are therefore not immediately accelerated to their final peripheral speed in the holder. Part of the acceleration can take place before they are fed into the
- the holder forms a holding space in which the propagation fruits can be loosely contained during operation.
- the propagation fruits are therefore not actively held in their respective holder by clamping means, pricks or other holding means. They therefore lie in the chamber without any holding means and their position is defined during operation only by the centrifugal and weight forces acting.
- the propagation fruits therefore align themselves in the chamber during operation due to centrifugal and gravitational forces, which leads to an optimal alignment depending on the size, shape and weight of the respective propagation fruit. This leads to a more controlled release in a lower release area of the laying wheel, whereby the release direction results from the holder depending on the time of release.
- the seed is released horizontally from the pick-up or the propagation fruit, against the direction of travel, to the rear.
- the earth's gravity accelerates the propagation fruit towards the bottom of the furrow.
- the propagation fruits are preferably released from the respective pick-up between the 4 and 6 o'clock positions, in particular between the 5 and 6 o'clock positions, in each case in relation to the rotating laying wheel, which is considered to rotate clockwise.
- Each receiving space is limited during the circumferential movement that occurs during operation in such a way that the propagation crop cannot pass through any of the sides of the receiving space that delimit the receiving space, at least during a section of movement in the laying wheel.
- the receiving space is thus limited in a way that is specific to the propagation crop, whereby these limits can be closed lateral limits, e.g. continuous walls, bars and/or grids.
- the drive device for driving the laying wheel can work purely mechanically and be coupled to the ground, for example, with a ground wheel or another means of contact in such a way that the movement of the laying device along the ground and with the possible use of an optional adjustment gear creates a torque and the wheel is set in rotation.
- an adjustment gear can also be a drive coupled to a tractor hydraulic system in the form of a hydraulic motor, a
- the drive can be a hydraulic motor independent of the tractor hydraulics or an electric motor, each of which can be part of the laying device.
- the drive can also be part of the drive device as an electric motor.
- the drive acts in particular on a shaft of the respective laying wheel 6, whereby in a laying device with several laying wheels these can be arranged together on the same shaft and can be designed to be individually switched off.
- the drive device comprises in particular a control unit, which can be part of the (machine) control of the laying device.
- the respective receptacles are at least partially formed by two side boundaries in the direction of the longitudinal center axis.
- the receiving space of the receptacle is located at least partially between these -fixed- side boundaries, which can be formed, for example, with continuously closed, rod-like and/or grid-like elements.
- tarpaulin-like boundaries for example made of PU, can also be used, which reduces the manufacturing costs.
- the laying wheel advantageously has at least one preferably circular frame element, which also forms the holder.
- the circular frame element can, for example, form one of the sides described above or hold them. It is used in particular for fastening further parts of the holder or the laying wheel.
- the struts serving to support the bearing in the area of the central axis or other frame elements of the guide wheel that hold the mount can be attached.
- a circular ring-shaped element is understood to be a frame element that has a closed shape running around the central axis without reaching the central axis. It does not have to have an exact ring shape, but only has to have a web that runs completely around the longitudinal central axis and is therefore closed.
- a side boundary or side of the receiving space can also be formed by a disc-shaped or approximately disc-shaped frame element which extends up to the central axis.
- the storage container is arranged at least partially on the inside between the receptacles.
- On the inside between the receptacles means that the storage container is crossed or at least touched by a straight line running perpendicular to the central axis, which runs from one receptacle to a receptacle located on an opposite side of the central axis. This straight line intersects or at least touches the receptacle.
- the propagation fruits can thus be kept in an area that is formed between the receptacles and therefore within the laying wheel. This makes particularly good use of the available installation space.
- the laying wheel therefore has an interior that, when viewed in a direction transverse to the central axis, is covered or possibly covered by the parts of the laying wheel that form the receptacles.
- the laying device is advantageously designed with an inner scooping area, which is designed so that scooping elements of the laying device can reach through.
- This scooping area can be part of the storage container.
- the scooping area can alternatively be designed as a scooping chamber or scooping container, a part of the laying device that is separate from the storage container and is filled by the storage container, which can be located separately in another position, outside the laying wheel.
- Such filling can take place via one or more feed elements in the form of a belt conveyor, for example. This enables optimal filling of the scooping area, regardless of the fill level of the storage bunker.
- the boundaries of the storage area and the scooping area are in particular at least partially formed by closed walls, bars or grids.
- the scooping area is designed as a scooping chamber or scooping container, its walls form a cross-section that tapers downwards to enable the scooping elements to be filled properly. During operation, the scooping elements pass through the scooping area from bottom to top.
- an inner scooping area i.e. an area which, viewed in a direction transverse to the central axis, is formed on the same axis position as the receptacles and in particular with a receiving opening of the receptacles, enables the use of scooping elements known per se, which, for example, in so-called cup-laying machines, in which the scooping elements are attached to the outside of a rotating belt.
- the separation takes place within the laying wheel from the scooping area in the direction of the receiving opening, with the scooping elements being arranged on the laying wheel.
- the respective scooping elements of the laying wheel describe curved paths in and above a scooping area, in particular according to their fastening position, so that any double assignments on a scooping element are better avoided.
- the scoop container can be monitored by means of a level sensor, for example in the form of an ultrasonic sensor or in the form of a camera.
- a level sensor for example in the form of an ultrasonic sensor or in the form of a camera.
- each scooping element is arranged on the laying wheel in such a way that, during operation, it describes a path that runs through the scooping area and is closed in the circumferential direction around the central axis.
- the scooping elements are part of the laying wheel and are preferably located on the inside of the same, so that they can be moved through a scooping area at a reduced circumferential speed compared to other driving elements of previous laying wheels.
- the laying wheel is provided with two offset rows of scooping elements in the direction transverse to the central axis.
- the scooping elements of the two rows of scooping elements are distributed so evenly around the circumference that, viewed in the direction of the central axis, the scooping elements of the two rows alternate evenly. Accordingly, successive scooping element receptacles in the circumferential direction that are assigned to different rows of scooping elements are filled.
- the scooping elements are preferably arranged movably on the laying wheel in such a way that they can transport the propagation fruits at least in the direction of the receiving opening and in particular at least partially through it.
- the receiving opening can be closed on the inside by at least one movable inner closure element, whereby the inner closure element can form a boundary of the receiving space in the direction of the longitudinal center axis.
- the inner closure element is arranged on a frame element or part of the laying wheel so that it can move relative to other elements forming the receiving space and is preferably pivotable.
- the inner closure element In its closed position, the inner closure element prevents a transfer of propagation fruits between the receptacle and an inner area of the laying wheel, in particular a scooping area.
- at least one inner closure spring element and/or an inner closure cam track element that guides the inner closure element during operation can advantageously be assigned to each respective inner closure element.
- an inner closure spring element in combination with an inner closure cam track element a forced movement can be triggered during the movement of the laying wheel around the central axis via an associated guide mechanism that guides the inner closure element by means of the inner closure cam track element.
- the guide mechanism comprises, for example, a guide roller that is pressed onto the inner closure cam track element by means of the inner closure spring element and that at least indirectly controls a movement of the inner closure element via a lever.
- the inner locking element can be opened and closed in a targeted manner during a rotational movement of the guide wheel by means of a contour of the inner locking cam track element, its end and/or a forced guide of the inner locking element into a position due to a spring element.
- the guide mechanism for the inner locking element and/or the inner locking element itself can be provided with an overload and/or breakage protection device, which, for example, varies an electrical signal in the event of an overload or breakage, which can be displayed to an operator as an error.
- the inner closure element can advantageously be pivoted about a pivot axis that runs at least approximately parallel to the central axis, whereby "at least approximately parallel” in this case is defined as a deviation of less than 20° between the central axis and the pivot axis. This allows the available installation space to be used more effectively.
- the pivoting takes place in particular by means of a pivot element that is moved via a lever to which the guide roller is attached.
- the inner closure element is formed by the scooping element and/or can be pivoted together with it.
- the scooping element can be guided accordingly over an inner closure cam track by means of an inner closure cam track element and any inner closure spring element, in particular at least partially forced and designed as a relatively movable part of the laying wheel.
- the inner closure cam track element can be subjected to force by a spring, for example, so that, except for any cases of overload, a forced guidance of the scooping element results.
- sufficient play can be provided against the movement of the spring in order, for example, to prevent damage to the propagation fruit or the mechanism for transferring the propagation fruit into the respective
- An internal closure cam track element can be provided with a profile to generate a shaking movement, which helps to avoid double occupancy of a scoop element.
- the internal closure cam track element can be actively stimulated, for example via a shaking motor and a sufficiently flexible fastening of the internal closure cam track element.
- the inner closure element can be formed by the scooping element, which serves on the one hand for receiving propagation fruits from the scooping area and on the other hand for closing the receiving space on the inside after the transfer of a propagation fruit into the receiving area.
- the scooping element directly forms the receiving opening and/or delimits it, in particular to the extent that the scooping element is at least moved through the receiving opening or closes it.
- the scooping element advantageously extends with its largest surface area at least approximately in the direction of the central axis, while in the closed position it is angled accordingly and pivoted inwards to limit the receiving space. In this position in particular, the scooping element acts as an internal closure element.
- an inner closure element is present in addition to the scooping element, this extends with its planar extension in particular transversely to a planar extension of the scooping element, so that in the scooping position of the scooping element, the receiving opening is closed and no propagation fruits can penetrate uncontrollably into the receiving area or the receiving space.
- the scooping element can also form a surface that is angled to the actual receiving surface and closes the receiving opening when the scooping element is in the scooping position.
- the scooping element can then be pivoted into a position due to its movable bearing and a motor or other, e.g. curved path-controlled guide in which it transfers the propagation fruit into the receptacle at least partially and in particular completely, and the scooping element closes the receiving opening.
- the receptacles advantageously each have a dispensing opening which is arranged on a circumferential side opposite the dispensing opening in relation to a respective dispensing space.
- This side is a side of the laying wheel which is offset radially outwards from the dispensing opening in relation to the central axis.
- the dispensing fruits are dispensed through the dispensing opening, which is at least briefly unlocked or open when the laying wheel is in operation to dispense the propagation fruit, during operation below the laying wheel. While in the dispensing space, the propagation fruits are additionally accelerated. Due to centrifugal and gravity forces, they align themselves during the rotation in the laying wheel in front of or, depending on the dispensing opening, already in the dispensing opening.
- the receptacle is formed by at least one side section which is angled and/or oblique with respect to a vertical to the central axis.
- the side section delimits the receiving space formed by the receptacle. It can be a section or part of a side boundary or side wall, thus a boundary in the circumferential direction or in the direction of the central axis. Alternatively or additionally, it can be a boundary on the circumferential side, so that a radial, outer side boundary or outer wall is formed by elements having areas that are angled accordingly to one another.
- each receptacle has two conical or side sections that run towards one another when viewed in the circumferential direction, which result in centrifugal and weight-related positioning of the propagation fruit during its movement around the central axis.
- the propagation fruit is forced to position accordingly during operation due to the shape of the sides and is thus aligned appropriately for discharge in a discharge area of the laying wheel during operation.
- a respective dispensing opening can be closed by at least one external closure element, preferably two external closure elements, in particular flap-shaped.
- the peripheral side can in particular be formed by the external closure element(s) in their closed position.
- the external closure element is movably attached to a frame part of the laying wheel, for example the aforementioned circular ring-shaped frame element.
- each external closure element is preferably assigned at least one external closure spring element and/or an external closure cam track element that guides the external closure element during operation.
- the external closure element describes a predefined movement during the rotation of the guide wheel around the central axis, depending on the course of the external closure cam track element, which, for example, is synchronous with the rotation.
- the external closure elements can also be guided along the external closure cam track element via a respective guide mechanism and transferred by this into the respective position.
- the inner closure element and the outer closure element of a respective receptacle can be coupled to one another and moved via the same guide mechanism.
- the opening of the external closure elements for example due to a change in the shape of the curved track element, preferably takes place in the contact areas of the propagation fruits, in particular in the area of the ends remote from a pivot axis of the external closure elements with an acceleration of the external closure elements in particular greater than the acceleration due to gravity, so that the propagation fruits to be released towards the substrate are not influenced by contact with the external closure element.
- a (external closure and/or internal closure) curved track element is a guide element which is formed at least in sections around the central axis and is fixed relative to the laying wheel, along the contour or surface of which a coupling element, e.g. a guide wheel, which moves with the laying wheel is guided and a movement of the coupling element is brought about via contour changes. It is also conceivable that a curved track on both sides forms a forced guide for a guided element which is connected to the scooping element or internal closure element.
- the outer closure and inner closure curved track elements can in particular be formed by the same curved track element, whereby the movement of the inner and outer closure elements are mechanically coupled to one another and these closure elements have the same guide mechanism.
- the outer closure spring element can simultaneously be the inner closure spring element.
- the outer closure element closes at the same time as the propagation fruit is transferred into the receptacle and the respective scooping element moves into a position suitable for scooping a propagation fruit when the associated outer closure element(s) is transferred into the open position of the receptacle.
- the movement of the two closure elements is then synchronized.
- the inner and/or outer closure elements can alternatively be opened and closed by motor, for which electric motors in particular can be used.
- the dispensing opening can be covered by a cover element arranged at least partially around the laying wheel.
- This can be a flat element made of plastic or sheet metal.
- the cover element is a belt that runs during operation, which can partially rest on the laying wheel and thereby drive it if necessary, or which alternatively or additionally runs so close to the laying wheel in terms of its path that the propagation fruits do not fall out of the holder.
- the belt has a polygonal or curved path along the laying wheel.
- the laying wheel itself can drive the cover element. Both the cover element and the laying wheel can also have their own drives.
- the drive device comprises a belt drive for the belt and is configured such that the belt speed is greater than or equal to the peripheral speed of the part of the laying wheel that is furthest away in the radial direction. This has an additional influence on the positioning of the propagation fruit in the receiving chamber, in particular in a lower area of the laying wheel.
- a belt running straight on the outside in the same direction which also closes the dispensing opening, provides additional positioning of the propagation fruit relative to the leading wall or side in addition to the centrifugal and gravitational forces, so that if the dispensing opening is abruptly opened, for example by an abrupt deflection of the belt or an abrupt opening of the external closure elements, the propagation fruit falls out of the receiving space without receiving an additional impulse from a subsequent wall that changes its trajectory.
- gravity acts directly on the propagation fruit, so that it is accelerated towards the ground in a controlled manner.
- a belt drive can, for example, include an electric motor as a drive.
- the belt drive can also be coupled to the drive of the laying wheel and its speed can be adapted to the outer circumference of the receiving space by means of appropriate gears.
- the belt drive can also be coupled to the laying wheel itself.
- the receiving space increases radially outwards in the circumferential direction.
- a point located correspondingly far away from the central axis thus also ensures a more defined delivery position.
- the resulting centrifugal and centrifugal forces prepare the release of the respective propagation fruit from a receptacle as a whole via the movement of the laying wheel around the central axis.
- a control unit is provided for driving the laying wheel.
- This control unit of the laying device ensures that the laying wheel is driven around the longitudinal axis and can also be designed to drive the associated belt and any other controllable parts of the laying wheel.
- the laying device can have one drive per laying wheel, but if several laying wheels are used it can also have a common drive for all laying wheels, for example with a continuous shaft and a decoupling option for individual driving lanes.
- the control unit processes signals of the driving speed in particular in order to adjust the wheel speed accordingly and to maintain it as precisely as possible without major fluctuations.
- control unit can have an automatic speed control, in particular depending on a fill level of the storage container and/or the scooping area, so that, for example, a feed element can be made to run faster in order to bring about an improved filling of the scooping area from a storage container.
- control unit is designed to receive signals from a level sensor of the storage container or the scoop chamber and its scoop container to adjust the feeding and/or releasing speed of the propagation fruits.
- the control unit is designed to process signals from the driving speed and/or an inclination sensor of the laying device to adjust the delivery of propagation crops. For example, if the laying device is inclined about a transverse axis that runs parallel to the center axis of the laying device, the impact position of the propagation crop on the ground can be varied by changing the delivery speed and thus the rotation speed. If the driving speed is reduced, the control unit can adjust the speed of the laying wheel to maintain the desired laying distance.
- a variation in the time or location of delivery can also be achieved with a curved track element by pivoting the curved track element about the central axis.
- the curved track element can be pivotably mounted via elongated holes, for example, with an adjusting means, e.g. in the form of a cylinder, holding the curved track element pivotable about the central axis.
- control unit can be designed to take into account the data from one or more speed sensors of the laying wheel in order to adjust the speed of the laying wheel if necessary.
- the scooping area is formed by a container that tapers downwards, thus reducing the width of the scooping area in the direction of an inlet opening for any scooping elements.
- control unit is designed to control at least one actuating means of a furrow-forming and/or ridge-forming element, so that the furrow is filled in earlier or later by releasing a propagation crop onto the ground, depending on the ambient conditions.
- the receiving openings are located on sides of the receptacles extending away from the central axis, which can facilitate the feeding of the propagation fruits from a bunker.
- the receiving openings can be arranged, for example, on a left and/or right side of the respective receptacles viewed transversely to the central axis, in particular alternately in the circumferential direction; alternatively or additionally, they can be arranged partially on the sides facing the central axis, on the inner side of the receptacle with respect to this axis, and thus also be formed at an angle.

- a laying device 2 according to the invention in the present case designed as a potato planting machine, has a bunker 4 in which propagation crops 5 in the form of potato tubers are stored (Fig. 1).
- the laying device 2 also has several laying wheels 6, the central axis 8 (Fig. 2) of which is aligned transversely to the direction of travel F.
- the laying wheels 6 are rotated by means of a drive device drive 9 which can be designed as an electric or hydraulic motor and which acts on a shaft (not shown) of the respective laying wheel 6.
- the laying wheels 6 can generally be driven on a common shaft and can be switched off individually. They can also be driven individually via their own drives.
- the drive device comprises a control unit 44, which can be part of the control of the laying device 2.
- the laying wheels 6 are rotatably mounted in a frame 10 of the laying device 2 and each have receptacles 12, partly shown in dashed lines, for the individual propagation fruits 5 along their circumference (see Fig. 1 and 2).
- Propagation fruits 5 are transferred from the storage container 4 in the direction of a scooping area 14 and collected there for transfer to the receptacles 12.
- the laying wheels 6 rotate in the circumferential direction U during operation.
- Furrow-pulling elements 50 form furrows for depositing the propagation fruits 5.
- the scooping area 14 or the container forming it is provided with a tapering cross-section towards the bottom and funnel-shaped walls 15 which converge towards one another and has one or two passage openings 13 at its lower end for internal closure elements designed as scooping elements 16 (Fig. 3).
- the scooping elements 16 are pivotally mounted on a ring-shaped frame element 18 forming the inner sides of the receptacles 12 and, viewed in a direction transverse to the central axis 8, form two rows of scooping elements 16 arranged alternately offset from one another.
- Each scooping element 16 is assigned a further closure element 17 set at an angle thereto, by means of which an inner receiving opening 19 of the receptacles 12 is closed when the scooping elements 16 are moved through the scooping space or scooping area 14.
- the receiving openings 19 are thus formed in the inner sides of the receptacles located towards the central axis 8.
- the receptacles 12 Radially offset outwards, the receptacles 12 have discharge openings 20 (cf. Fig. 4), through which the propagation fruits fall out of the laying wheel 6 at the lower end due to gravity.
- a receptacle 12 thus has a receiving space with its lateral boundaries and openings.
- the receiving space of the receptacles 12 tapers radially outwards due to converging side walls or side boundaries 21 (Fig. 4).
- the propagation fruits 5, which are moved outwards due to centrifugal force during rotation about a rotation axis or central axis 8, are centered outwards to a central and release position.
- Each receptacle 12 is provided on the circumference with flap-shaped external closure elements 22 which are guided by a cam track element 24 which forms an external closure cam track element and which corresponds in shape to that of the embodiment according to Fig. 7 (Fig. 5). Due to a mechanical coupling, further (inner) closure elements 17 and external closure elements 22 of a respective receptacle are synchronized in terms of movement.
- each receptacle 12 has its own guide mechanism, whereby only one and the same, possibly multi-part, external closure cam track element 24 is used. Closing the inner receptacle opening 19 is accompanied by a transfer of the respective external closure elements 22 into the closed position. An inner closure cam track element and the external closure cam track element are both formed by the cam track element 24.
- FIG. 5 shows a perspective view of a receptacle 12 in an approximate 12 o'clock position.
- a respective inner closure element is pivotally fixed to the frame element 18 via a pivot element 33 having a pivot axis 23.
- the frame element 18 rotates as part of the guide wheel 6 along the curved track element 24, which is arranged fixedly on the frame 10 of the laying device 2.
- Via a lever arm 26, a guide roller 28 on a surface 29 of the curved track element 24 causes a controlled movement of the pivot axis 23 and, along with it, of the inner closure element formed by the scooping element 16 and the further closure element 17.
- a spring 25 acts on the pivot axis 23 by means of a pivot lever 26 and presses the guide roller 28 against the surface 29 of the curved track element 24. Without the curved track element 24, the scooping element 16 would be in an open position and the receiving opening 19 would be closed by the further closure element 17.
- a wall 27 delimiting the receiving space in the circumferential direction (cf. Fig. 3) is not shown in Fig. 5.
- a spring 31 serves as an overload protection in the connection of the inner locking element with the further locking element 17.
- the position of the surface 29 controls the relative movement of the scooping elements 16 during their movement through the scooping area 14 until they reach the closed position in the 12 o'clock position (see Fig. 2 and 3).
- a propagation fruit 5 is still lying on the inner closure element in the 12 o'clock position due to gravity.
- the outer closure elements 22 controlled by a lever 32 remain in the closed position shown (Fig. 5).
- the outer closure element 22 is pivotally mounted on the side walls or side boundaries 21.
- a change in the contour of the curved track element 24 leads to the 6 o'clock position of the holder 12 due to the guide roller 28 guided along the surface 29 leads to a sudden opening of the outer closure elements 22.
- a belt 38 represents a covering element which covers a plurality of receptacles 12 in the lower right quadrant of the laying wheel 6 on the outside and thus prevents unwanted removal of the propagation fruits from the receptacles 12 (Fig. 6).
- the belt is driven by an electric motor 42 as a belt drive, which receives signals from the control unit 44 during operation.
- the supply of propagation fruits into the scooping area 14 is also controlled by this control unit 44, which is designed as part of the machine control of the laying device.
- the belt 38 rests circumferentially on the receptacles 12 and can drive the laying wheel 6 via this contact, in particular a friction and/or form fit.
- the sectional view according to Fig. 7 shows the movement sequence of the The scooping area 14 shows the individual propagation fruits 5. Starting from the scooping area 14, the propagation fruits 5 are transferred into the receiving space of the respective receptacle 12 by means of a movement of the scooping elements 16 controlled by a further curved track element 24.
- the closed position of the scooping elements 16 from the 12 o'clock position to the 6 o'clock position corresponds to the starting position of the opening and closing mechanism. This starting position is assumed due to the force exerted by springs 25 on the mechanism of the individual receptacles 12.
- the scooping elements 16 are transferred to a position or open position suitable for scooping propagation fruits 5.
- the curved track element 24 moves away from the pickup space so that the scooping elements gradually move into the closed position reached in the 12 o'clock position. From the 9 o'clock position, the curved track runs in such a way that the scooping elements 16 are aligned approximately horizontally with their pickup area and the propagation fruits remain on the scooping element 16.
- the belt 38 closes the receiving space of the holder 12 on the outside so that the propagation fruits 5, which are further accelerated due to centrifugal and gravity forces, remain in the holder until the 6 o'clock position in particular.
- a deflection roller 40 that is as small as possible, a defined transition of the propagation fruits into the free fall and in a direction opposite to the direction of travel F, so that after a gentle pickup and two-part acceleration phase of the propagation fruit, it is precisely released into the furrow.
- the laying wheel 6 shown in Fig. 8 has a series of receptacles, the receiving openings of which, viewed in the circumferential direction, are located alternately on the left and right side - viewed transversely to the central axis 8 of the laying wheel 6.
