Abstract

PURPOSE:To correctly plant seedling to planting bed at a constant interval pitch by transferring seedling individually lifted from throwing belt with separating arm onto arranging belt passing through introducing tunnel with nipping roller and introducing the seedling into seedling-transferring belt. CONSTITUTION:Seedlings M randomly thrown on a throwing belt 31 are stopped with a seedling-controlling plate 38 and a fulculum shaft 39 for seedling- excluding body, then the seedling M are separated in individually lifted state by intermittent rising and lowering motion of a seedling separating arm 40 and intermittent rotating vibration motion of a seedling-excluding body 48. Thus, individual root part of the seedling M is received by nipping rollers 58 and passed through an introducing tunnel 56 in nipped state, then laid on an arranging belt 33 in pulled out and thrown state, thus introduced onto a seedling- transferring belt leading to a seedling-transplanting disk.

Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a seedling feeding device for a seedling transplanter.

<Conventional technology> Green onion seedlings are planted in the field using a transplanter that automatically and mechanically plants the seedlings on the floor.The machine uses a seedling input belt mounted horizontally on the top of the machine, and a rotatably pivoted support on the bottom of the machine. There is a known type of seedling planting system that is equipped with a disc and a seedling transfer belt placed vertically between the upper and lower sides of the disc, and for this purpose, the seedlings are placed horizontally on the feeding belt. Seedlings are fed out downward while being held by a transfer belt, and then the seedlings are received and held by a disk for planting, and as the disk rotates, the seedlings are planted on the floor.

<Problems to be Solved by the Invention> However, in order to supply seedlings to the transfer belt of such a seedling transplanter, conventionally, an operator has to manually collect a bundle of seedlings from a seedling storage magazine or the like. The pieces are separated one by one, and each piece is placed horizontally on the loading belt.

For this reason, planting using disks is an extremely difficult task, as is planting on the floor, but maintaining a constant pitch between the seedlings is extremely difficult, and the work requires very little time and is very strenuous work. It has become.

In this regard, as a measure to plant the seedlings at a constant pitch, as mentioned above, each of the seedlings is
It is also possible to temporarily maintain the fixed state with a stirring tape, but it is difficult to make the pitch constant, but it requires complicated preliminary work, and it is still difficult to improve work efficiency. I can't.

It is also conceivable to automatically and mechanically pick up seedlings one by one from a bundle of seedlings stacked in a seedling storage magazine or the like using clamping claws and transfer them to the feeding belt. In that case, if the leaves of adjacent seedlings are intertwined, this will act as separation resistance on the gripping claws, and the seedlings will easily fall off from the gripping claws.

However, if the viewing power of the gripping claws were to be strengthened, it would damage the seedlings and inhibit their growth. As a result, after planting with disks and planting on the bed, it is necessary to carry out extremely troublesome work of replenishing and repairing missing or damaged seedlings.

Such problems are not limited to the above-mentioned green onion seedlings, but can be said to occur in exactly the same way when using the above-mentioned type of transplanter for various seedlings with similar rod-shaped root parts.

<Means for solving the problem> The present invention is intended to fundamentally solve the problem,
For this purpose, for planting seedlings on the floor, a seedling transplanter is equipped with a disk and a seedling transfer belt to the disk, and the seedlings are introduced into the seedling transfer belt. As a feeding device, there is a seedling feeding belt which is pivotally supported to the device frame so that it can freely circulate around the horizontal axis, and the retractable belt is arranged side by side, which is also pivotally supported to the device frame so that it can freely circulate around the horizontal axis. a seedling alignment belt, a seedling regulating plate erected at the end point of the conveying action of the seedlings by the belt in order to keep the seedlings randomly placed on the feeding belt in a horizontal position in a converged state; In order to push up and separate the seedlings that have been dammed up by the pair of fulcrum shafts for the seedling rejector, their regulating plates, and the fulcrum shafts, from the base of the seedlings, automatic intermittent lifting and lowering that appears from below the seedling input belt is performed. In conjunction with the moving seedling separation arm and the vertical movement of the separation arm, the seedling separation arm oscillates and rotates about the fulcrum shaft, so as to move automatically and intermittently into the vertical movement path of the separation arm. a seedling removing body that shakes off excess seedlings onto the feeding belt; an inlet facing the root of the seedlings that will be pushed up one by one as a result, and an outlet opening on the upper surface of the seedling alignment belt. In this situation, the device consists of a seedling guiding tunnel that is fixed and horizontally suspended on the device frame, and a pair of seedling holding rollers that are mounted on the shaft at the entrance of the tunnel, and the separating arm pushes up the seedlings one by one from the feeding belt The separated root portions of the seedlings are received and held by the holding rollers, and transferred by the rotating motion of the rollers to the alignment belt through the guiding tunnel, and the transferred seedlings are automatically placed on the alignment belt. The main feature is that the seedlings are arranged sideways at a constant pitch, and the arrangement belt is introduced into the seedling transfer belt.

<Example> Hereinafter, the present invention will be described in detail based on the drawings.
Figure 3 shows the overall outline of a transplanted machine that has been realized for painting green onions. (A) is the general term for the machine body, and the engine (10) is mounted on the front part of the machine. (11) is a roller that runs, and is driven to rotate by the engine (10) via a transmission belt (12), a transmission mechanism (not shown) in a transmission case (13), etc. (14) is the control handle, and (15) is the work rate, where the worker who has applied IIjP in a backward posture will load and place the seedlings (M) on the seedling loading belt of the seedling feeding device, which will be described later. .

(16) is a furrow cutter suspended from the middle part of the adult (A>), which allows the planting of seedlings (M) in the field.
) is cut out <, (17) is a generic name for the seedling planting disk that is located immediately after the groove-making device (16) and is attached to the machine body (A) via the rotating support shaft (18). Yes, its pivot (
18) is connected to the transmission mechanism via the transmission chain 7 (19), and is also rotationally driven by the engine (10). At this time, it goes without saying that the disk (17) is driven at the same speed in synchronization with the running roller (work 1).

This disk (I7) is composed of a pair of left and right elastic membrane plates (20) that face each other, and receives the pressing force of the plate springs (21) from the lateral outside of the disk, thereby elastically holding the seedling (M). As it rotates, the plants are transferred to the floor (G) and planted as shown in Figure 1.2.

In other words, a pair of left and right spring receiving plates (22) facing the center of rotation of the disk (17) are attached and fixed to the fuselage (A), and a plurality of leaf springs (21) are attached to the spring receiving plates (22). are locally and intensively ejected in a radial manner toward the front half of the circumferential surface of the disk (17), and the disk (17) itself is This gives it an elastic force that allows it to hold the seedling (M) without interfering with the rotational action of the seedling (M).

(24) In (25), the above-mentioned planting is a covering ring and a pressing ring for the later seedlings (M), and in both cases, the planting is transferred to the bed (G). (26) is a stabilizing axis of the fuselage (A), and is suspended from a support arm (27) extending laterally outward of the fuselage (A).

Also, (B) is a seedling supply device frame erected at the rear of the machine body (A) so as to correspond to the position above the planting disk (17).
A seedling transfer belt (28) that correctly introduces the seedlings (M) from above into the first half of the circumferential surface of the disk (17) circulates around a horizontal axis (29) perpendicular to the rotational axis (18) of the disk (17). It is pivoted in a vertically running state.

The transfer belt (28) consists of a set of left and right belts capable of elastically holding the seedling (M), and the belt silk faces the elastic membrane plate (20) of the disk (17) in a corresponding positional relationship. At the same time, the seedling (M) has a disk (
As is clear from FIG. 1, it is designed to be transported in a horizontally exposed state exposed from the circumferential surface of 17).

The present invention is a seedling feeding device (C) for sequentially introducing seedlings (M) to the seedling transfer belt (28) of such a transplanter, and is assembled to the device frame (B) with the following configuration. is unitized.

That is, the seedling feeding device (C) is shown on the horizontal axis (2) of the seedling transfer belt (28) as shown in FIGS.
In addition to the seedling loading bell 1-(31) which is axially mounted on the device frame (B), there is also a horizontal position where it circulates around the horizontal axis (30) parallel to 9). The horizontal axis (32)
A seedling alignment belt (3
3>, and the end position of the transporting action of the seedlings (M) by the alignment belt (33) is determined by the seedling transfer belt (2).
8), so as to be in direct communication with the starting point position of the seedling conveyance action.

While keeping the seedling (M) on its side, the seedling transfer helper I is used to turn the seedling (M) downward from the alignment belt (33).
- (28) can be smoothly introduced. The seedling input belt (31) and the seedling alignment belt (33) are also rotated and driven by the engine (10) mounted on the transplanter, like the seedling transfer belt (28).

(34) (35) are integrated sprocket wheels attached to one end of each horizontal shaft (30) (32) in the input belt (31) and alignment belt (31), <36)
(37) is each sprocket wheel (34) (35
) suggests a power transmission check 7 with 1 applied to it.

In that case, in the figure, the adjacent front and rear pairs of the seedling alignment belt (33) and the seedling feeding belt (31) are arranged in parallel at the same installation height, but the installation height may be changed. After the step condition, the two types of belts (31
) (33) may be assembled to the device frame (B) by the horizontal shafts (30) and (32), respectively.

In addition, in the figure, the conveyance direction (Fl) of the seedling alignment belt (33) toward the starting point of the seedling conveyance action of the seedling conveyance belt (28)
In contrast, the conveyance direction (F2) of the seedling input belt (31) is different from this direction, so that the two types of belts (31) and (33) can be assembled to the device frame (B). When attaching the seedling feeding belt (31) and (33), the seedling feeding belt (33) is installed side by side.
The conveyance direction (F2) of 31) may be set in the same direction as that of the seedling alignment belt (33).

In any case, the seedling feeding belt (31) is the 4.5th
As is clear from the figure, a certain space (S) is formed between a plurality of belt sets arranged in parallel to the horizontal axis (30), and a certain space (S) is opened between the plurality of adjacent belt sets. . (38) and (39) are seedling regulation plates and seedling exclusion plates that are separately fixed and erected from the device frame (B) so as to penetrate the space (S) at the end point of the seedling conveyance action of the seedling input belt (31). The former stands vertically, while the latter has a seedling loading belt (31
), so to speak, it stands tilted at a certain angle (α) in a direction that conforms to the conveying direction (F2), and its fulcrum axis (39) forms the pivoting fulcrum of the seedling remover, which will be described later. The reason why this is erected in an inclined state will be described later.

In that case, the seedling regulating plate (38) is the seedling alignment belt (33).
), and the fulcrum shaft (39) is located on the outside of the seedling input belt (31), which also maintains a long distance. The interval (W) has been cleared, and the seedling input bell is on! - They are distributed in a horizontal manner on the same virtual transverse line (X-X) of (31).

Therefore, the seedling input belt (31) can circulate smoothly without interfering with the seedling regulating plate (38) or the fulcrum shaft (39). Moreover, the above fixed interval (W)
Since the length of the seedling (M) is narrower than the length of the seedling (M), the seedling (M) placed horizontally on the seedling input belt (31) will be at the end point of the conveyance action of the belt (31). As soon as it reaches the point, it is automatically stopped in a convergent state by the restriction tFi (38) and the fulcrum shaft (39), and is restricted to a posture that correctly crosses the input belt (31).

The seedling regulating plate ( It goes without saying that the standing heights of 38) and the fulcrum shaft (39) were appropriately selected.

(40) is a seedling separation arm that moves up and down automatically intermittently so that it comes in and out from below through the space (S) of the seedling input belt (31) while being close to the position just in front of the seedling regulation plate (38). As shown in Figure 6, it has an overall abbreviated shape, and the tip of one piece faces the root of the dammed seedling (M), and the seedling (M) is placed at the root. It is supported in an inclined position at a fixed angle (β) by being pushed up from the ground.

In other words, the seedling separation arm (40) is connected to the seedling input belt (31).
The base end of the other piece is attached to the device frame (B) via the pivot pin (41). (42) is a drive motor for the separation arm (40), and its rotation output shaft and the separation arm (40)
0) and the middle part of the other piece in the crank arm (43
) are pivotally connected.

Therefore, the rotational action of the motor (42) is caused by the separation arm (
40), and its arm (40)
is raised to a certain height position (the end point of the lifting action) so that the tip of the seedling is exposed from the seedling input belt (31). (44) is a cam surface formed in the middle of one piece of the separation arm (40), and is raised in the direction opposite to the conveyance direction (F2) of the seedling input belt (31); It will be operatively connected to the seedling expelling body which will be described later.

At this time, the reason why one piece of the seedling separation arm (40) is curved into an arc shape as shown in FIG. 6 is that the seedlings (M ) and to support the seedling (M) as stably as possible. Similarly, the reason why one piece of the separation arm (40) is placed close to the position just in front of the seedling regulation plate (38) is that the regulation plate (38) not only serves to dam the seedlings (M), but also to prevent the separation arm ( 40) so that the seedling (M) can be pushed up without fear of falling off. From that meaning, i! r regulation plate (
38) is also curved in an arc shape corresponding to one piece of the sorting arm (40).

The tip of one piece of the seedling separation arm (40) is F
5 (M) is formed into a bifurcated shape so as to be able to receive one root part at a time, but as shown in FIG. It is preferable to prepare a two-pronged socket (45) and attach it to the distal end of the separation arm (40) in a detachable and replaceable manner.

Then, by using the socket (45) interchangeably,
This is because it can quickly and accurately respond to changes in the type of seedling (M), changes in the thickness of its root portion, etc., and can push up the seedling (M) reliably and stably. In addition, the reference numeral (46) in the figure is a rectangular groove cut out at the tip of the separation arm (40) in order to receive the socket (45), and (47) is a rectangular groove cut into the recess (46). The fixing screw of the inserted socket (45) is shown.

(48) is a seedling removing body that shakes off the excess amount of seedlings (M) pushed up by the separating arm (40), and swings and rotates around the vertical axis in conjunction with the vertical movement of the separating arm (40). As a result, the separation arm (40) moves back and forth in a transverse manner to the elevation passage.

That is, the exclusion bodies (48) of the extra seedlings (M) are the 10th to 14th
As is clear from the figure, the shaft cylinder (49) is loosely fitted onto the fulcrum shaft (39), and from its mid-height position toward the lifting passage of the seedling separation arm (40), A hollow swinging arm (50) integrally extended over the seedling input belt (31), a flexible wire shaft (51) conductively wired inside the swinging arm (50),
A rotating impeller (52) is located at the protruding tip of the rotating arm (50) and is integrally attached to the wire shaft (51), and a seedling separation arm is also attached to the lower end of the shaft tube (49). (40), the interlocking arm (53), which is also integrally extended, and the free-rotating roller (54), which is pivotally supported at the distal end of the interlocking arm (53), A roller (54) contacts a piece of the seedling separation arm (40) from the front and is adapted to climb up and down its cam surface (44).

Due to the contact between the cam surface (44) of the seedling separation arm (40) and the idler roller (54) of the seedling removal body (48), the two are operatively linked. At the end of the lowering action of the arm (40), the idler roller (54) of the seedling remover (48) descends from the cam surface (44) of the separation arm (40), as suggested from Figure 10.11. Therefore, the rotating arm (50) advances toward the lifting passage of the separation arm (40), and the rotary impeller (52) at its protruding tip moves toward the separation arm (40) as shown in FIG. 14 (1). It is located directly above the

When the separation arm (40) acts upward to push up the seedling (M), it comes close to the rotary impeller (52) as shown in FIG. 14(n), so the excess seedling (M) The seeds are immediately thrown off onto the seedling feeding belt (31) by the rotational force of the impeller (52). Subsequently, as the separation arm (40) approaches the end point of its upward action, the idle roller (54) of the seedling remover (48) climbs up to its cam surface (44) as shown in Fig. 12.13. As a result, the swing arm (50) swings around the fulcrum shaft (39), and the impeller (52) at the protruding tip moves into the first
As shown in FIG. 4 (III), the separation arm (40) is evacuated from the lifting passage.

The retracted state is maintained even at the beginning of the descent from the end point of the ascending action, and the separation arm (40) returns to the end point of the descending action without any trouble. Therefore, if the rotating arm (50) of the seedling removing body (48) is arranged so as to cross the lifting passage of the seedling separating arm (40), it is possible to
) The separation arm (40) can move up and down smoothly without fear of interference with the other parts. '' The profile of the two-dimensional human face (44) is designed based on such temporal timing.

As I said earlier, the seedling input belt (31) has a seedling (M
) are piled up on their side and placed in a haphazard manner, so if their leaves and roots become intertwined, several seedlings (M) will be separated by the separating arm (40).
I don't have to worry about being pushed up at half an hour. In this regard, since the removing body (48) is installed which automatically rotates intermittently in conjunction with the raising and lowering action of the seedling separation arm (40), it is possible to reliably push up the seedlings (M) one by one. It is.

The above-mentioned rotary impeller (52) is made of rubber, synthetic resin, etc., and the impeller (52) directly faces the lifting passage of the seedling separation arm (40) and rotates in the direction of the arrow (R). The action results in brushing off the excess amount of seedlings (M) from the separation arm (40). In that case, the above-mentioned seedling excluder (
In particular, the fulcrum shaft (39) of the rotating arm (50) in
) is erected in a tilted state at a certain angle (α) so that it falls in the same direction as the conveyance direction (F2) of the seedling input belt (31), so the swing arm (50) is tilted in the direction shown in FIG.
As shown by the arrow (D) in I), the seedling separation arm (40) advances and retreats from the diagonally upward direction into the lifting path, and together with the rotation direction (R) of its impeller (52), -
The excess seedlings (M) can be reliably brushed off and removed.

Also, as is clear from Figure 9.14, the seedling separation arm (4
Seedling regulation plate (38
A relief recess (55) for the impeller (52) is formed at a mid-height position of the separation arm (40).
), the impeller (52) is positioned directly above the separation arm (40). From this point of view, the effect of eliminating the above-mentioned extra seedlings (M) can be significantly improved.

In addition, the excess amount of seedlings (M) that have been shaken off onto the seedling input belt (31) are transferred again by the seedling regulation plate (38) and the fulcrum shaft (39) as the conveyance action of the seedling input belt (31) is carried out. Needless to say, it will be dammed up and will be subject to the next uplifting action.

(56) is a seedling guide tunnel fixedly supported on the device frame (B) as a bridge that crosses the seedling arranging belt (33) adjacent to the seedling input belt (31), and is preferably made of transparent material. It is made of synthetic resin or the like and has an inverted U-shape cross section as shown in Figure 7. Moreover, that tunnel (
56) is an extended state of the fourth to It is curved in an arch shape when viewed from the side as shown in Figure 6.

In other words, the entrance part (a) of the tunnel (56) is
While correctly facing the base of the seedling (M) pushed up by the seedling alignment belt (33), the outlet (b)
) is fully open on the top surface, and the above-mentioned seedling is pushed up (M)
is received from its base, guided downward smoothly and effortlessly along its curved arched upper wall surface, and transferred onto the alignment belt (33) while lying on its side. There is.

In that case, the exit part (b) of the tunnel (56) is installed on the base end side in the figure, and by positioning it at the lateral end of the seedling alignment belt (33), the tunnel (56) can be attached to the device frame (B). It is erected in a so-called cantilevered state,
As far as the inducing effect of the seedlings (M) described above can be distantly related, for example, a gate-shaped pillar (not shown) interposed between adjacent seedling alignment belts (33) and seedling feeding belts (31), It may be erected integrally from the device frame (B), and the entrance portion (a) side of the tunnel (56) may be supported by its pillars.

In any case, the entrance part (a) of the seedling guiding tunnel (56)
is located at a certain height, and a roller support plate (57) facing above the seedling input belt (31) is integrally protruded and extended from its upper wall surface. And its support plate (57
) has a pair of seedling clamping rollers (5B) facing each other.
It is rotatably supported.

The pair of pinching rollers (58) are made of highly elastic rubber or synthetic resin, and are interposed between the end point of the lifting action of the seedling separating arm (40) and the entrance portion (a) of the seedling guiding tunnel (56). Then, while the root portion of the seedling (M) pushed up is held by the separation arm (40), the seedling (M) is guided into the tunnel (56) by the high-speed rotational force of the holding roller (58). Instantly retracts and aligns belt (33
) It works in a straight line to remove the cargo and transfer it to the top.

For this purpose, a drive motor (59) for the nipping roller (58) is installed on the roller support plate (57) extending from the tunnel (56), and a pair of opposing rollers (58) is connected to a pulley. (60) and the torn transmission belt (60)
1), the seedlings (M) are rotated in opposite directions through which the seedlings (M) can be drawn. The base end of the flexible wire shaft (51>) is transmission connected to one of the pulleys (60) so as to rotate integrally with the flexible wire shaft (51), thereby causing the impeller (52) to move in the direction of the arrow (R). It is designed to rotate at high speed.

At this point, the drive motor (59) of the pinching roller (58)
If the impeller (52) can also be rotationally driven while also serving as a motor, the output pulley (62) can be attached and integrated on the rotating shaft of the motor (59), as shown in the modified example of FIG. 15, which corresponds to FIG. The transmission belt (61) may be hooked to the non-crossed state between the output pulley (62) and the pulleys (60) of both the nipping rollers (58).

In addition, the rotational support shaft (63) of the nipping roller (58) and the rotational output shaft (64) of the motor (59) are in a relationship state in which both of them are correctly perpendicular to the seedling (M>) pushed up by the separation arm (40). 6, as suggested by Figure 6.

In the above configuration, the seedlings (M) are supplied from above to the seedling transfer belt (28) of the transplanter, and the seedling planting by rotating the seedlings (M) is performed by the disk (17). is the floor (G)
When planting the seedlings (M), use the seedling feeding device (
The seedlings may be placed on the seedling feeding belt (31) in C) at random while lying on its side.

Then, the placed seedling (M) will be transferred to the feeding belt (3
1), the seedlings are transported in the direction of the arrow (F2) in Figure 4.5, and as soon as they reach the end point of the transport action, the seedlings are self-sustaining by the fulcrum shaft (39) and the seedling regulating plate (38) that stands up at that position. Even if the materials are thrown in in a convergent state, even if they are thrown in randomly, the blocking action results in the correcting of the transverse posture of the feeding belt (31) in an orderly manner.

Since a seedling separation arm (40) that moves up and down is placed directly below the root of the dammed seedling (M), the lifting action of the separation arm (40) causes the seedling (M) to move up and down. ) will be pushed up from the feeding belt (31) and separated from the rest of the seedlings (M).In other words, the seedlings (M) transported by the feeding belt (31) will be separated from the remaining seedlings (M). They are automatically separated one after another from those in the front row in a tilted posture in which the base portion floats at the above-mentioned constant angle (β).

At that time, a seedling remover (
The rotating arm (50) of 48) crosses, and the rotary impeller (52) at the tip faces the position directly above the separation arm (40), so that during the lifting process of the separation arm (40), , even if several seedlings (M) are pushed up, the excess amount will be removed by the high speed rotation of the impeller (52).
The seedlings (M) are instantly thrown onto the seedling input belt (31), and the seedlings (M) are definitely pushed up one by one.

Further, as the separation arm (40) approaches the end point of the lifting action, the swivel arm (50) of the excluder (48) moves towards the separation arm (
Through the contact action between the cam surface (44) of 40) and the idle roller (54), the impeller (52) swings around its fulcrum shaft (39), and the above-mentioned impeller (52) moves up and down the lifting path of the separation arm (40). Since the separating arm (40) is retracted from the position, the separating arm (40) can move upward to the end position without any hindrance.

The root parts of the seedlings (M) that have been pushed up and separated one by one in this way are continuously received and held by the seedling holding roller (58) facing directly above them, and the high speed rotation of the roller (58) causes the seedlings to be separated. Guidance tunnel (56)
The seedlings are instantly and straightly pulled out through the seedlings, and are orderly transferred onto another seedling arranging belt (33) adjacent to the seedling input belt (31).

During the above action, the seedling alignment belt (33) circulates at a constant speed, and the seedling separation arm (40) automatically moves up and down intermittently to collect the pushed up seedlings (M). Since each seedling (M) is immediately removed by the pinching roller (58), the seedlings (M) that have been removed and transferred are placed on the alignment belt (33) so that the adjacent seedlings (M) are separated from each other. is a constant pitch as shown in Figure 4.5 (
P), the result is that they are automatically and correctly aligned one after the other as they are laid down on their side.

Therefore, by keeping the raising/lowering speed of the seedling separating arm (40) constant and changing the seedling conveying speed of the seedling alignment belt (33) in relation to this to be faster or slower, the above-mentioned interval pitch (P ) can be adjusted wide or narrow. In addition, in contrast to this, if the speed of the seedling conveying action of the seedling alignment belt (33) is constant, the seedling separation arm (4)
It can be said that even if the speed of the vertical movement (0) is changed, the above-mentioned interval pitch (P) can be adjusted widely. By the way,
In the figure, the interval pitch (
P) is set in a range of about 25 to 50 mm.

The seedlings (M) that have been pulled out and transferred onto the alignment belt (33) are continuously moved by the seedling transfer belt (28), which is continuous and coincident with the conveyance end point position of the alignment belt (33). The planting is fed out in a downward direction as shown in the figure, and is introduced into the first half of the circumferential surface of the disk (17), and as the disk (17) rotates,
It goes without saying that the planting in the field is done on the floor (G) after the above-mentioned interval pitch (P).

<Effects of the Invention> As described above, in the present invention, seedlings are planted on the bed (G) using a seedling system equipped with a disk (17) and a seedling transfer belt (28) to the disk (17). By assembling it into the transplanter, the device frame (
Circulation around the horizontal axis to B) As the seedling input belt (31) is pivotally supported and the input belt (31) is placed side by side, the seedling input belt (31) is also rotated around the horizontal axis to the device frame (B). A seedling alignment belt (33) is pivotably supported, and a seedling belt (31) is used to collect seedlings (M) which are randomly placed in a sideways position onto the feeding belt (31) in order to keep them in a concentrated state. A seedling regulation plate (38) and a fulcrum shaft (39
), the lower part of the seedling feeding belt (31) is used to push up the seedlings (M), which have been dammed up by the pair of regulating plates (38) and the fulcrum shaft (39), up to a distance of 5 degrees from the base of the seedlings (M). A fraction arm (40
), and in conjunction with the vertical movement of the separation arm (40), it moves intermittently toward the vertical movement of the separation arm (40).
A seedling discharging body (48) swings around the fulcrum shaft (39) and shakes off the excess amount of the pushed up seedlings (11, ri) onto the input pitcher (31).
As a result, the seedlings are pushed up one by one (
The inlet part (a) faces the root part of M), and the outlet part (b)
As a bridging state in which the seedling alignment belt (33) opens on the upper surface, a seedling guide tunnel (56) fixedly installed horizontally on the device frame (B) and an entrance portion (a) of the tunnel (56) are connected to each other. It consists of a pair of axially mounted seedling clamping rollers (58), and the root portions of the seedlings (M), which have been pushed up and separated one by one from the feeding belt (31) by the separation arm (40), are transferred to the clamping rollers (58). ), the seedlings (M>) are received and held by the rollers (58), and are transferred to the alignment belt (33) through the guiding tunnel (56) in a continuous manner by the rotational movement of the roller (58), and the transferred seedlings (M> and a constant pitch (P
