On the other hand, some farming methods are used to transplant seedlings without plowing the paddy fields where rice and igusa have been harvested. If seedlings are transplanted to a field where no plowing is performed by using a seedling planter, the holes in which the seedlings are transplanted are not fully backfilled, and the posture and survival of the seedlings are unstable. In order to improve this, a plant was developed in which a plowing device was attached to a seedling planter, a part of the field was tilled in a streak pattern, and seedlings were transplanted to the plowing trace.
Then, this seedling planting machine is provided with a seedling planting device and a tilling device integrally, and by supporting them with a gauge wheel rolling on the surface of the field, the height of the seedling planting device is maintained and the seedling planting device is maintained. It was set up to determine the implantation depth.

２が下降する。Therefore, during the seedling transplanting operation, the traveling vehicle body 1 is
The front wheels 4 and the rear wheels 5 rotate on the surface A of the field and move forward.
At this time, the gauge wheel 52 is lowered by its own weight of the tiller 19 and the tension of the spring 55, and rolls on the surface A of the field. Then, each plowing claw 48 plows a part of the field in a streaky manner to a certain depth, and the plowing claws 34 are formed at the respective plowing traces.
Transplants seedlings. When the traveling vehicle body 1 comes to a soft place in the field, the front wheels 4 and the rear wheels 5 sink due to their own weight, and the seedling planting device 2 also descends. However, the tiller 19 uses the gauge wheel 52.
It does not descend because it is supported by. That is, the chain case 44 rotates clockwise with respect to the gear box 20 in FIG. When the subsidence amount of the traveling vehicle body 1 exceeds a certain limit, the wire 59 moves the valve 12 to the right by the above-mentioned rotation of the chain case 44, the oil passage is switched to "up", and the seedling planting device 2 rises. To do. In this way, when the seedling planting device 2 is raised to a certain height, the angle of the chain case 44 with respect to this is returned to the standard state, the valve 12 is returned to the "neutral" position, and the rise is stopped. When the traveling vehicle body 1 comes to a hard place in the field, the subsidence of the front wheels 4 and the rear wheels 5 is reduced and the seedling planting device 2 is listed from the surface A. Then, the chain case 44
Rotates counterclockwise with respect to the gear box 20, and when the rotation exceeds the limit, the wire 59 loosens and the spring 56 causes the valve 12 to rotate.
To the left, the oil passage is switched to “down”, and the seedling planting device 2 descends.

置２の上下動にも対応できるものである。As is well known in the seedling planting machine, the lever 18
When is operated to “raise”, the valve 12 switches the oil passage to “raise” in preference to the above switching, and the seedling planting device 2 is raised. And when this lever 18 is operated to "down",
When the valve 12 moves to the left, the oil passage is switched to “down”, the seedling planting device 2 descends, and when this descends to a certain position,
Chain case 4 supported on the surface A by the gauge wheel 52
The angle between 4 and the gear box 20 reaches a certain range, the valve 12 returns to the right and becomes "neutral", and the above descent is stopped. After that, as described above, the valve 12 automatically switches the oil passage according to the sinking amount of the traveling vehicle body 1. Also, this configuration
It is also possible to cope with the vertical movement of the seedling planting device 2 due to the forward and backward inclination of the traveling vehicle body 1 due to the unevenness of the field scene.

下による前後バランスの悪化に対応することができる。As shown in FIG. 3, the seedling planting device 2 is attached to the working machine frame 10.
It can be provided so as to be movable in the front-back direction. That is, the rolling shaft 21 of FIG. 1 is composed of a rod 61 having a piston 60 in the middle, and the cylinder 22 is composed of a hydraulic cylinder 62. A valve 64 is provided between the pump 63 and the hydraulic cylinder 62, and a front and rear lever 65 is provided.
And this is designed to move. In FIG. 3, the valve 64
Is located at “neutral”, the oil is closed in the hydraulic cylinder 62, and the seedling planting device 2 does not move back and forth. When the front-rear lever 65 is operated in the clockwise direction, the valve 64 is pulled by the wire 66 and moved to the left, and the oil discharged by the pump 63 is transferred to the hydraulic cylinder 6
As the oil in the front chamber returns to the tank 67 and the piston 60 moves forward, the seedling planting device 2 approaches the working machine frame 10 as it enters the rear chamber. On the contrary, when the front / rear lever 65 is operated in the counterclockwise direction, the wire 66 is loosened and the valve 64 of FIG.
Is pushed by the spring 68 and moves to the right, the oil discharged by the pump 63 enters the front chamber of the hydraulic cylinder 62, the oil in the chamber returns to the tank 67, the piston 60 moves backward, and the seedling planting device 2 moves. Move to later. Therefore, when the plowing device 19 is lifted up like a chain line and used, the seedling planting device 2 is moved forward and used in a well-balanced manner, and when the plowing device 19 is lowered and used, the seedling planting device 2 is moved backward to form the plowing claw. It can be used so that 48 does not contact the rear wheel 5. As a result, in normal rice planting in which planting is performed after plowing the field, since the seedling planting device 2 is used in front, it is possible to cope with deterioration of the front-rear balance due to wheel subsidence in the field in the plowing state. .

Only the points of difference in configuration from those shown in FIGS. 1 and 2 will be described below. The tilling device 19 is composed of three sets of chain cases 44, support rods 45, etc., and is arranged in front of each planting case 24. The intermediate chain case 44 and the rear end of the support rod 45 are rotatably provided on both sides of the gear box 20. A toothed wheel 71 and a toothed wheel 72 corresponding to the toothed wheel 30 and the toothed wheel 50 of FIG. 2 are integrally provided with the intermediate cam 73, are rotatably attached to the main shaft 25, and are pushed by a spring 74 to move the tooth wheel 71 of the toothed wheel 71. The lateral claw 75 is engaged with the claw of the fixing plate 76. The chain 31 is wound around each tooth 71 and tooth 32, and the tooth wheels 72 on both sides are
Chain 51 is wrapped around the tooth ring 49. An intermediate shaft 77 is provided in the gear box 20 and a toothed wheel 78 fixed to the gear box 20.
A chain 79 is wrapped around the tooth 72 at the center.
The toothed wheel 80 is fixed to the end of the intermediate shaft 77, and a chain 81 is wound around this and the toothed wheel 49 at the center.

Are extended from the respective pins 81 and can be operated by the respective levers 84 on the upper part of the seedling table 37. A wire 85 extends from the lever 84, and the lower end is attached to the middle of each chain case 44.

付条における耕起の重複を防止できる。Therefore, when the desired lever 84 is operated in the clockwise direction from the position shown in FIG. 4, the wire 85 is pulled to rotate the chain case 44 in the clockwise direction, and the plowing claw 48 at the tip thereof floats above the ground. . At this time, the wire 83 is loosened and the pin 8
1 is pushed out by the spring 82. Then, the tip of the pin 81 engages with the cam 73, the cam 73, the toothed wheel 71, and the toothed wheel 72 move laterally against the spring 74, and the claw 75 causes the fixing plate 7 to move.
The claw 6 is separated from the claw 6 and the transmission power from the main shaft 25 is stopped, and the rotation of the tilling claw 48 that has floated from the ground and the subsequent claw 34 is stopped at the same time. When the lever 84 is operated in the opposite direction, the plowing claw 48 descends in the opposite direction, and at the same time, the plowing claw 34 behind the plowing claw 48 resumes rotation. Therefore, it is possible to easily stop and restart the desired plowing claw 48 and the planting claw 34 at the shore, and it is possible to prevent duplication of plowing in the planting strip.
