Definitions

  • the invention relates to a seed on demand system according to the preamble of patent claim 1.
  • the seed on demand system comprises the storage container for the granular material, at least one blower to provide a conveying air flow, and a distribution device.
  • the distribution device has a distributor housing which is set up by means of a material inlet opening to receive material from the storage container.
  • the distributor housing has a conveying air opening for directing the conveying air flow in the direction of the picked-up material in order to generate a mixed flow of conveying air and material.
  • the distribution device has a distribution segment which forms at least one line with a receiving opening and an outlet opening, the line being arranged to receive at least part of the mixed flow by means of the receiving opening and discharge it from the outlet opening.
  • the object on which the invention is based is therefore to avoid disturbances in the distribution of the material and at the same time to generate the mixed flow in an energy-efficient manner.
  • This problem is solved by a seed on demand system with the features of claim 1 . Further advantageous refinements and developments of the invention are specified in the dependent claims.
  • the invention proposes a seed-on-demand system for granular material, which comprises a storage container for granular material, at least one fan to provide a flow of conveying air, and a distribution device.
  • the distribution device has a distributor housing which is set up by means of a material inlet opening to receive material from the storage container.
  • the material inlet opening can be arranged at the top of the distributor housing so that the material slides into the distributor housing under the influence of gravity.
  • the distributor housing also has at least one conveying air opening in order to guide the conveying air flow in the direction of the picked-up material, so that a mixed flow of conveying air and material is generated.
  • the at least one conveying air opening is arranged in particular in such a way that granular material is whirled up and entrained with the conveying air flow without an actively driven dosing element being required which releases material in regulated quantities into the conveying air flow.
  • the dosing of the distribution device can also be described as automatic.
  • the conveying air flow is therefore responsible not only for conveying the material but also for metering it.
  • the distribution device also includes at least one distribution segment, which forms at least one first line with a first receiving opening and a first outlet opening.
  • the line is arranged in such a way that at least part of the mixed flow enters the receiving opening, in particular automatically, and can be discharged from the outlet opening.
  • the receiving opening is preferably arranged in the area where material is swirled in the conveying air flow and the mixed flow is thus created, so that the mixed flow can enter the line directly and easily.
  • at least one stirring element is arranged between the material inlet opening and the first receiving opening. The stirring element is thus arranged in the flow direction of the material on the way from the material inlet opening to the receiving opening.
  • the invention makes use of the finding that the use of a stirring element makes it considerably easier to generate the mixed flow.
  • clumping and sticky material is broken up so that it can be more easily swirled by the conveying air flow and enter the receiving opening as a mixed flow.
  • the mixed flow is thus homogenized, so that the distribution of material is made more uniform overall.
  • the conveying air flow thus requires less energy, so that the efficiency of the seed on demand system is improved and at the same time the functional reliability is increased. Bridging of the material can thus be effectively prevented, particularly when the material enters the distributor housing under the effect of gravity and, unlike in systems with an active dosing element, there is a heap in the lower area.
  • the stirring element is preferably at a distance from the receiving opening which corresponds at least to the clear diameter of the receiving opening.
  • a passive stirring element can be set up so that part of the picked-up material is passed over the stirring element and part is passed under the stirring element, so that the bulk material is loosened.
  • the stirring element can be at least approximately the same distance from an, in particular outer, side wall of the distributor housing as from the receiving opening.
  • the stirring element can be driven in a rotatable manner about an axis of rotation.
  • the axis of rotation is at a distance from the receiving opening which corresponds to at least twice the radius of the stirring element.
  • the stirring element can be designed in the manner of a whorl.
  • the stirring element can be a shaft with stirring fingers, the radius of the Stirring element can correspond to the radius of the shaft or the radius of the fingers.
  • the drive speed of the stirring element can be independent of the driving speed of the seed on demand system.
  • the mode of driving may be intermittent.
  • the stirring element can be driven when the seed-on-demand system is at a standstill and/or stand still at least temporarily while the seed-on-demand system is being used for the active distribution of granular material.
  • the axis of rotation has at least the same distance from an, in particular outer, side wall of the distribution housing as from the receiving opening.
  • the axis of rotation can be arranged equidistant to the receiving opening and to the side wall.
  • the distribution segment has at least two conveying air openings, the directions in which the conveying air flow is emitted enclose an angular range of less than 180 degrees, with the stirring element sweeping through the angular range at least temporarily.
  • the stirring element preferably has stirring fingers, which at least temporarily comb through the angular range, specifically particularly preferably when the stirring element is driven in rotation.
  • the directions in which the conveying air is discharged from the conveying air openings are decisive for the grain intake area, so that as a result of this measure, the grain intake area, which corresponds to the included angle range, is loosened up by the stirring element and thus improved.
  • the seed on demand system can have a large number of distribution segments which are arranged next to one another on an axis.
  • a particularly simple and expedient design of the stirring element is achieved in that the stirring element is designed as a stirring shaft which extends parallel to the axis.
  • a distribution segment forms at least one second line with a second receiving opening and a second outlet opening. It is preferably provided that at least one, in particular another, stirring element, preferably designed as a stirring shaft, is arranged between the material inlet opening and the second receiving opening.
  • Each stirring element can be assigned its own drive.
  • the line between the receiving opening and the outlet opening has a bypass opening in order to introduce a bypass flow of the conveying air flow, with the bypass opening being arranged directly above the receiving opening.
  • the bypass flow can therefore be introduced into the line without further flow obstacles or deflections in the direction of flow of the mixed flow, as a result of which the energy efficiency is further increased.
  • a first bypass opening can be arranged between the first receiving opening and the first outlet opening.
  • a second bypass opening can be arranged between the second receiving opening and the second outlet opening.
  • the bypass openings are preferably located horizontally next to one another, so that the bypass flows are introduced into the respective line at the same level above the receiving opening. The promotion is thus further homogenized.
  • a common drive which is set up to drive both stirring elements, in particular stirring shafts.
  • a chain or belt and/or at least two drive elements, such as gear wheels, can be provided for this purpose. Expediently, therefore, only a single drive is required for two stirring elements. It is also advantageous here that both stirring elements can preferably be driven in the same way.
  • the drive can be controlled independently of the driving speed of the Seed on Demand system.
  • the drive mode can be intermittent, in particular the stirring elements can be driven when the seed-on-demand system is at a standstill.
  • the first line is symmetrical to the second line and/or the stirring elements with respect to a vertical axis of the distribution segment or a point on the vertical axis and/or are.
  • a symmetrical arrangement of the first and second line relative to the vertical axis or a point on the vertical axis also improves the absorption of the mixed flow by means of the intake openings.
  • a symmetrical arrangement of the stirring elements in the manner described above also ensures a particularly homogeneous generation of the mixed flow.
  • the first and second lines and the stirring elements are arranged symmetrically about the same point on the vertical axis.
  • the first and second lines are arranged symmetrically to the stirring elements opposite the vertical axis or a point on the vertical axis.
  • the equalization of the mixed flow and thus the energy efficiency and functional reliability of the seed on demand system is also advantageously increased in that the stirring elements are arranged in a common horizontal plane. Since the subsequent sliding of granular material under gravity when generating the mixed flow has a significant effect on the turbulence caused by the conveying air flow, the arrangement of the stirring elements, in particular the stirring shafts, at the same height has proven to be particularly beneficial.
  • the stirring element extends between opposite end faces of the distributor housing, in particular through all of the distribution segments.
  • the mounting of the stirring element in the end faces of the distributor housing enables simple assembly and functional testing.
  • the Seed on Demand system according to the invention is also advantageously developed by at least one overpressure-operated separating device for the granular material.
  • a special synergy with the stirring element results from the use of a separating device operated by overpressure: In the separating device there is an overpressure which ensures that granular material accumulates on a preferably rotating separating element.
  • the granular material reaches the separating device via the mixed flow, with the mixed flow also having a positive air pressure in order to be able to convey the granular material.
  • a separating air stream for separating can have a lower air pressure than the mixed flow.
  • the mixed flow is promoted against the air pressure of the separating air flow. Since at least the required air pressure for conveying the granular material can be reduced as a result of the stirring element according to the invention, the pressure difference between the mixed flow and the separating air flow decreases.
  • the Seed on Demand system is therefore designed to be particularly efficient.
  • the Seed on Demand system preferably has at least as many separating devices as there are outlet openings.
  • An energy reduction element, in particular a catch roller, can be assigned to the separating device for the separating delivery of the granular material.
  • the stirring element can be driven to rotate about an axis of rotation, with the direction of rotation being reversible, preferably within one revolution.
  • interval operation can be implemented, with the direction of rotation changing after a predetermined number of revolutions, so that particularly thorough mixing occurs. This is particularly beneficial to prevent bridging of treated seeds.
  • the direction of rotation can be reversed within one revolution, resulting in a pendulum movement.
  • FIG. 3 shows the distribution device according to FIG. 2 in a first sectional view
  • FIG. 4 shows the distribution device according to FIG. 2 in a second sectional view
  • FIG. 5 shows the distribution device according to FIG. 2 in a third sectional view.
  • a seed on demand system 1 for granular material is shown symbolically in FIG.
  • the seed-on-demand system 1 comprises a storage container 2, a blower 3 and a distribution device 4, as well as a plurality of overpressure-operated separating devices 5, only three separating devices 5 being shown here for the sake of clarity.
  • the seed on demand system 1 is intended to distribute granular material from the storage container 2 to the separating devices 5 by means of the distribution device 4 with the aid of the blower 3 .
  • the blower 3 provides a flow of conveying air 6 which swirls granular material in the distribution device 4 and thus generates a mixed flow 7 .
  • the granular material is made available to the separating devices 5 via the mixed flow 7 .
  • the distribution device 4 can be arranged under the storage container 2, so that the granular material slides down under the influence of gravity.
  • the seed on demand system 1 can include several storage containers 2 with an associated distribution device 4 .
  • more than a single fan 3 can be provided in order to provide the conveying air flow 6 and the separating air flows 8 .
  • the seed-on-demand system 1 has a separate blower each for providing the conveying air flow 6 and the separating air flows 8 .
  • the flow path marked with the reference number 8 feeds out in this embodiment, which is not shown a second additional blower 3.
  • the separating air flow 8 has a lower air pressure than the mixed flow 7.
  • the distribution device 4 can be seen in FIG. 2 in a perspective view.
  • the distribution device 4 has a distributor housing 9 which, by means of a material inlet opening 10 on its upper side, is designed to receive material from the storage container 2 .
  • a circular air inlet is arranged on the end face of the distributor housing 9 in order to introduce the conveying air flow 6 into the distributor housing 9 .
  • the flow of conveying air 6 is guided in the direction of the material picked up by means of a plurality of conveying air openings 11a - f in order to generate the mixed flows 7 .
  • the conveying air openings 11a-f can be seen in the sectional view 1-1 in Fig.3. It is also clear here that the distribution device 4 has a plurality of distribution segments 12a-f. Each of the distribution segments 12a-f has two conveying air openings 11a-f, as can also be seen from the sectional view II-II in FIG.
  • the distribution segments 12a-f each form a first line 13a-f and a second line 13'a-f.
  • the lines 13a-f, 13'a-f each have a receiving opening 14a-f, 14'a-f and an outlet opening 15a-f, 15'a-f.
  • the lines 13a-f, 13'a-f are arranged in such a way that the granular material, after being swirled by the conveying air flow 6, i.e. as a mixed flow 7, is automatically received through the receiving openings 14a-f, 14'a-f, rises and finally is discharged from the outlet openings 15a - f, 15'a - f.
  • a stirring element designed as a stirring shaft 16 is arranged between the material inlet opening 10 and the first receiving opening 14a-f.
  • the agitator shaft 16 loosens the material in the area where the conveying air flow 6 is directed onto the material.
  • the agitator shaft 16 is arranged in the flow direction of the material from the material inlet opening 10 to the receiving openings 14a-f, 14'a-f between these two openings.
  • On the opposite side of the distribution segments 12a-f a further agitator shaft 16' is arranged between the material inlet opening 10 and the second receiving openings 14'a-f.
  • a common drive 17 is assigned to the agitator shafts 16, 16' in order to drive them in rotation about their axis of rotation.
  • the direction of rotation of the agitator shafts 16, 16' can be reversed, in particular within one revolution, in order to intensify the mixing effect and prevent bridging.
  • the drive 17 is drive-connected to the two agitator shafts 16, 16' via gears, so that, assuming the gears have the same gear ratio, the agitator shafts 16, 16' can be driven in the same way.
  • the drive can be controlled independently of a travel speed and/or at intervals.
  • a drive connection via at least one chain, belt or the like is also conceivable.
  • the first and second lines 13a-f, 13'a-f and the stirring shafts 16, 16' are arranged symmetrically with respect to a vertical axis V.
  • the first and second lines 13a-f, 13'a-f and the stirring shafts 16, 16' are arranged symmetrically with respect to one, preferably each, point on the vertical axis V.
  • the agitator shafts 16, 16' are arranged in a common horizontal plane H and their axis of rotation is at a distance from the receiving opening 14f, 14'f which is at least corresponds to twice the radius of the agitator shaft 16, 16'.
  • this distance represents an optimal compromise between an arrangement close to the grain intake and sufficient distance to avoid bridging, so that the loosening of the granular material near the intake opening 14a-f, 14'a-f is improved.

  • the mode of operation of the distribution device 4 can be clearly explained using the sectional view II-II through the distribution segment 12f, which can be seen in FIG.

This is particularly advantageous because the separating air flow 8 has a lower air pressure than the mixed flow 7 and can therefore also be generated with reduced energy consumption.
  • the Seed on Demand System 1 is thus improved not only with regard to its functional reliability but also its energy efficiency.
