The bearing 59 is provided between the crank arm 60a of the crank shaft 60 rotatably supported on the planting frame 32 around the left and right axes. Of the crank pin 60b is inserted. Accordingly, the rotation of the crankshaft 60 in the counterclockwise direction in FIG. 6 causes the planting body 53 to swing up and down while swinging up and down due to swinging of the first and second parallel links 56 and 58. Then, the plant 53 moves with respect to the traveling body 2 so as to draw a vertically long substantially elliptical trajectory. Then, seedlings are dropped and supplied to the planted body 53 at the upper end side of the track, and the planted body 53 is lowered with the lower opening device closed, and the opening device enters the ridge 5, and after the entry, The opening device is opened back and forth by the interlocking tool 61 to form a planting hole in the ridge 5, and the seedling stored in the planting body 53 is released into the planting hole, so that the seedling is ridged. 5 planted.

4 can be freely changed in a vertical locking position with respect to the lever 65, so that the vertical spacing between the soil covering / pressing wheel 37 and the planting frame 32 can be adjusted, thereby setting the planting depth of the seedling. Adjustments can be made.

It should be noted that the adjustment of the implantation depth can be performed from the left side of the rear part of the transplanter 1 in conjunction with the left and right implantation devices 34. This is because the worker walks on the left side of the rear part of the transplanter 1, so that the planting depth farther from the worker can be easily adjusted. As described above, the left and right seedling placing stands 35 are supported by the support frame 38 so as to be movable in the left-right direction, and place and support the seedling tray T in a backwardly inclined state. As shown in FIG. It has a mounting plate 66 that supports the bottom of the seedling tray T. The mounting plate 66 is arranged and fixed between a pair of left and right side plates 67.

An endless chain 72 is mounted between the driving sprocket 70 and the driven sprocket 71, and a gap between the pot portions P of the seedling tray T in the vertical direction (up and down direction) is provided on the chain 72. The transport pin 73 that engages with is mounted to protrude inward in the left-right direction. Therefore, the drive shaft 68
However, by rotating in the direction indicated by arrow A in FIG. 7, the seedling tray T is pushed by the transport pin 73 and can be fed vertically.

A transverse feed shaft is formed between the left and right connecting members 43 of the support frame 38 and formed with a special screw (napya screw) which penetrates the right and left seedling mounting table 35 and is connected to the valleys of the right and left screws cut at the same pitch. A lateral feed shaft 74 is supported rotatably. A slider 75 that engages with a special screw on the lateral feed shaft 74 is externally fitted. The slider 75 is connected to a pair of left and right engaging pieces 76 provided on the back surface of the mounting plate 66 of the seedling mounting table 35.

The transverse feed shaft 74 is intermittently driven to rotate. When the transverse feed shaft 74 is driven to rotate intermittently, the slider 75 moves intermittently in the left-right direction and a screw formed on the transverse feed shaft 74 is formed. And the left and right seedling rests 35 are reciprocated in the left-right direction in synchronization with each other. The lateral feed shaft 74 is stopped when the seedlings are removed from the pot portion P by the seedling feeding device 36, and rotates after the seedlings are removed from the pot portion P, and the horizontal arrangement of the pot portions P is performed. It is configured to rotate intermittently so as to move the seedling mounting table 35 by one pitch in the direction (left-right direction).

A vertical feed cam 77 is fixed on the left and right sides of the left seedling platform 35 on the horizontal feed shaft 74, and a vertical feed operating shaft 78 is provided on the left seedling platform 35. The follower 7 engaging with the vertical feed cam 77 is provided on the feed operation shaft 78.
9 are provided as a pair on the left and right. Then, when the seedling placing table 35 moves to the left and right ends, the follower 79 is pushed by the vertical feed cam 77, the vertical feed operation shaft 78 rotates, and the vertical feed means 80 is operated via a link or the like. The vertical feed drive shaft 68 is rotated so as to transfer the seedling tray T by one pitch of the pot portion P in the vertical arrangement direction of the pot portion P (the arrangement direction orthogonal to the left-right direction).

Thus, when the removal of the soil block seedlings S from the horizontal row of pot portions P is completed, the seedling tray T is fed vertically by an amount corresponding to the vertical interval of the pot portions P. I have. The portion of the seedling tray T from which the seedlings have been taken out is folded back along the drive sprocket 70 toward the lower surface of the mounting plate 66. The seedling tray T is made of plastic, is formed to be thin, has flexibility, and has a large number of pot portions P arranged in a grid pattern at predetermined pitches in the vertical and horizontal directions. Are connected to each other in a planar manner. Then, the pot block P is filled with floor soil, sowed and seedling there, so that the soil block seedlings S are grown.

Each of the left and right seedling feeding devices 36 has a seedling removal claw 81 and a drive shaft 82 as shown in FIG. 8, and when the drive shaft 82 rotates counterclockwise from the state shown in FIG. The crank body 83 rotates together with the roller 85 fitted to the crank pin 84 to push the cam plate 86 to swing the extruding link 87 toward the seedling tray T, whereby the holding member 88 is held.
The nail support 90 is pushed toward the seedling tray T side to compress the springs 91 and 92. As a result, the seedling removal claw 81 protrudes and penetrates the block soil of the seedling S, and has a restoring force for the claw support 90 to retreat.

When the drive shaft 82 further rotates counterclockwise from this state, the roller 85 slides in the groove cam 94 of the swing arm 93, so that the swing arm 93 is rotated.
After swinging around A in a direction away from the seedling tray T, the seedling extraction nail 81 moves backward with respect to the seedling tray T together with the nail support 90, the nail guide 95, and the holder 88, and the block soil of the seedling S is placed in the pot. It is taken out from the part P.

Thereafter, when the drive shaft 82 further rotates counterclockwise, the claw support 90, the claw guide 95, and the holder 8
8, the seedling removal claw 81 moves in the direction away from the seedling tray T, and the roller 85 slides on the front rising portion of the cam groove 94, so that the seedling removal claw 81 and the like are changed to a substantially downward posture. The seedling S is placed in the planted body 53 while
Position above.

Then, when the seedling removal claw 81 is moved to a state in which the seedling removal claw 81 is in a substantially downward posture, the claw guide 95 is projected by the urging force of the spring 92, and the seedling S held by the seedling removal claw 81 is removed. Push it out of the claw 81 and remove it,
The plant 53 is dropped into the plant 53 from above. Thereafter, the driving shaft 82 is rotated in the counterclockwise direction in FIG. 8 to move to the state shown in FIG. 8, and the above operation is repeated.

As shown in FIGS. 2, 4 and 5, the seedling feeding device 36 is supported by a gear box 96 fixed to the main frame 32, and the input shaft 97 of the gear box 96 is connected to the bevel gears 50L and 50R. The interlocked bevel gear 98 is interlockingly connected via a universal joint 99, and the power transmitted to the input shaft 97 is transmitted to a gear box 96.
The drive shaft 82 of the seedling feeder 36 via a power transmission mechanism inside
The seedling feeding device 36 is driven by the power from the rotating shaft 49.

Further, an output shaft 100 projects rightward from the right gear box 96, and the output shaft 100 is supported by the support frame 38.
Transmission mechanism 1 in transmission case 101 fixed to the right side of
02 is interlockingly connected to the transverse feed shaft 74 via the second shaft 02, and is configured so that power is intermittently transmitted from the rotary shaft 49 to the transverse feed shaft 74 via an intermittent power transmission mechanism in the gear box 96. I have.

Further, the left gear box 96 is provided with a clutch K1.
Power can be connected and disconnected. When three-row planting is performed by the transplanter 1 having the above-described configuration, first, the tread is adjusted to an interval corresponding to the width of the three-row ridge, and as shown in FIG. By moving the attachment frame 33 and the like, the plant 5 of the right planting device 34 is moved.
3 is positioned at the center of the ridge 5 in the left-right direction (direction orthogonal to the longitudinal direction). At this time, the clutch K1 of the left gear box 96 and the clutch K2 of the power transmission system from the rotating shaft 49 to the planting device 34 on the left side are disconnected, and the seedling feeding device 36 and the planting device 34 on the left side are stopped. deep. Then, the seedling is planted at the center of the ridge 5 while the transplanter 1 is running in the longitudinal direction.

Next, a turn is made at the end (headland) of the ridge 5 and, as shown in FIG. It is moved to a position offset to the right from the center in the direction, and is moved to a position at the same distance as the distance from the center of the ridge of the planting body 53 on the left. Then, by connecting the clutch K1 of the left gear box 96 and the clutch K2 of the power transmission system from the rotating shaft 49 to the left implanting device 34, the implanting machine 1 is implanted on both the left and right sides while running in the longitudinal direction. By planting the seedlings on the left and right sides of the transplanted seedlings at the center of the ridge 5 by the device 34, three-row planting is performed.

Therefore, by reciprocating the ridge 5 once in the longitudinal direction, three-row planting can be performed, and the efficiency of the planting operation is high. In addition, you may make it plant two plants on both right and left first, and plant a ridge center part later. When two-row planting is performed, the tread is adjusted to an interval corresponding to the width of the two-row ridge, and the position from the center of the ridge of the right-side planting body 53 is adjusted to the center of the ridge of the left-side planting body 53. Set at the same distance as the distance from the part. In the case of four-row planting, the tread is adjusted to an interval corresponding to the ridge width for four rows, and the seedlings are planted between the right-side seedling planting position and the left-side seedling planting position. The planting body 53 on the right
Is performed, and the transplanting machine 1 is reciprocated in the longitudinal direction of the ridge 5 (therefore, two right-edge plantings are planted with the right-side planting body 53, and the left and right ends on the ridge are planted with the left-side planting body 53). 2).

In the above configuration, the tread adjustment is performed with respect to the right and left front wheels 10, 11 with respect to the left and front wheels 10, 11.
Since the left planting device 34 is fixed to the traveling machine body 2, the distance from the left-right end of the ridge of the left planting body 53 does not change. There is an advantage that it is not necessary to adjust the position of the left implant 53 even if the tread is adjusted.

FIG. 9 shows another example of the transplanting apparatus. The slider 75 is not provided on the right seedling mounting base 35, and the left and right seedling mounting bases 35 are connected by the connecting rod 103, so that the right and left seedling mounting bases 35 are connected. The seedling rest 35 is integrally moved to the left and right. The right end of the connecting rod 103 is fixed to the right seedling rest 35, and the right side of the connecting rod 103 is the right seedling rest. It is configured to be supported by a support member 104 fixed to 35 so as to be movable in the left-right direction, and to be fixed to the support member 104 by a fixing means 105 such as a pin or a bolt so as to be movable in the left-right direction. A lever 106 is provided on the left end side of the connecting rod 103.

Accordingly, when the fixing by the fixing means 105 is released and the lever 106 is pulled to the right, the worker can place the seedling tray T on the seedling mounting table 35 farther (right side) from the worker. The seedling tray T can be replaced without moving to the groove between the ridges on the opposite side of the ridges.
