a.20a is disposed as close to the front and rear as possible to the seedling planting position by the transplanting device 15. Therefore, as soon as the seedlings are planted, the pressure-reducing cylinders 20a and 20a surely cover and suppress the soil without shifting to the left and right with respect to the grooves and the seedlings.

Therefore, the seedling transplanter 1 runs on the ridges while running on the groove disks 19a and 19a of the groove generator 19.
a, a planting groove is formed, and seedlings are planted one by one with the transplanting device 15 in the planting groove.
A series of operations to suppress the soil cover at a.20a are performed (FIG. 10). The body of the seedling transplanter 1 is provided with a body posture control device that maintains the height of the top and bottom and the right and left with respect to the ridge surface at a predetermined height (FIGS. 1 to 6). The configuration will be described below according to the reference numerals in the figure.

Av is a hydraulic cylinder serving as an actuator for raising and lowering the body. The cylinder portion 21 of the hydraulic cylinder Av is fixed to a support plate 22 fixed between the frames 3a and 3b. A spring case 24a equipped with a spring 24 is fitted to the piston rod 23 of the hydraulic cylinder Av up to a step on the rod base side, and a piston arm 25 extending in the left-right direction is further provided at the center of the rod end. It is slidably engaged with the engaging hole of the section in the front-rear direction (the direction in which the piston moves). Therefore, the movement of the piston rod 23 is transmitted to the piston arm 25 via the spring 24 as a buffer. The piston arm 25 is provided with an arm sliding shaft 2 fixed between the support plate 22 and the horizontal frame 3c in an engagement hole at the lower center thereof.
6 slidably penetrates, and the rotation of the piston arm 25 around the piston rod 23 is restricted. Also,
The left and right ends of the piston arm 25 are connected to the left and right sides of the front wheel swing arms 7b, 7b integrated with the bosses 7a, 7a of the front wheel transmission cases 7, 7 of the front wheels 6, 6, respectively. As for the connection, the right side is directly connected by the rod 27, and the left side is
They are connected via a ring hydraulic cylinder Ar. The connection on the left side is, that is, the cylinder part 2 of the hydraulic cylinder Ar.
8 is connected to the left front wheel swing arm 7b, and the piston rod 29 is connected to the left end of the piston arm 25. Further, a rear wheel swing arm 31 is rotatably supported by a vertical shaft 30 on the upper part of the center of the piston arm 25, and the left and right ends of the arm 29 are connected to rear wheel support arms via connecting rods 32,32. Rear swing arm 9a integrated with
・ Connected to 9a.

As described above, the hydraulic cylinder A for lifting and lowering the fuselage
When v operates and its piston rod 23 moves rearward, both the front wheels 6.6 and the rear wheels 8.8 swing downward and the body rises. Conversely, when the piston rod 23 retreats forward, the front wheels 6.6 and the rear wheels 8.8 both swing upward and the body descends.

When the body is tilted to the right, the hydraulic cylinder Ar for rolling is actuated and its piston rod 2
When the cylinder 9 attempts to protrude rearward, the cylinder portion 28 moves forward to rotate the left front wheel swing arm 7b. Then, the left front wheel 6 swings upward,
The rightward tilt is corrected. Conversely, when the hydraulic cylinder Ar for rolling operates and the piston rod 29 attempts to retreat forward when the body tilts to the left, the cylinder portion 28 moves rearward and the left front wheel swing arm 7b Is rotated. Then, the left front wheel 6 swings downward, and the inclination to the left is corrected. In addition, rear wheel 8
In the rear wheel 8, the rear wheel oscillating arm 31 is freely rotatable around the vertical shaft 30, so that the right and left rear wheels 8, 8 can be freely rolled by the reaction force received from the ground.

Reference numeral 33 denotes a horizontal sensor. The pendulum 35 having a weight 35a, which is integrally attached to the hydraulic cylinder Av for lifting and lowering the fuselage, and is supported on a shaft 34 in the front-rear direction so as to be able to swing left and right, is moved by the swing of the pendulum 35. Hydraulic valve 3 for activating Ar
6 are connected so as to operate the spool 36a. Therefore, the horizontal sensor 33 detects that the pendulum 35 swings to the right with respect to the machine body when the machine body is tilted to the right.
6a is operated to switch the flow of the pressure oil so as to protrude and move the piston rod 29 of the rolling hydraulic cylinder Ar. On the other hand, if the body is tilted to the left, the pendulum 35 swings to the left with respect to the body to push the spool 36a, and the piston rod 2 of the rolling hydraulic cylinder Ar is moved.
9 is operated so as to switch the flow of the pressure oil so as to retreat the 9. When the airframe is in a horizontal state, the pendulum 35 is suspended vertically to the airframe, and the spool 36a blocks the flow of pressure oil to the hydraulic cylinder Ar.

Reference numeral 37 denotes a ridge height sensor.
The ridge surface grounding body 38 pivotally supported by the pivot 9 rotates up and down in accordance with a change in the height of the ridge with respect to the body while sliding on the upper surface of the ridge, and detects the ridge height. The ridged surface grounding member 38 has a support member 38a fixed on the front upper surface thereof.
Is connected to the sensor-support shaft 39 via a bracket 3 fixed to the left and right frames 3a and 3b.
It is supported by supporting arms 42 fixed to an adjusting shaft 41 that can be rotated by a planting depth lever 40 supported by a ′ and 3b ′. Therefore, by operating the planting depth lever 40, the reference position of the ridged surface grounding body 38 with respect to the machine body can be changed. In addition, the ridge surface grounding body 38 is formed of a plate-like member curved in the front-rear direction, and slides on the ridge surface while performing a ridge surface leveling action.

The support member 38 of the ridge height sensor 37
The valve operating arm 38b is integrated with the valve arm a, and is connected via a rod 44 to an operating plate 43b for operating a spool 43a of the hydraulic valve 43 for vertically moving the body and the tip of the arm 38b. . Further, a spring 45 is connected to the valve operation arm 38b so as to pull the ground contact portion of the ridge surface grounding body 38 downward in a rotating direction. Therefore, when the ridge-surface grounding body 38 rotates following the ridge height, the machine-body vertical hydraulic valve 43 is operated in conjunction therewith, and the machine-body vertical hydraulic cylinder Av operates.

That is, when the ridge surface rises with respect to the body, the ridge surface grounding body 38 is pushed up by the grounding portion, and pivots upward around the sensor support shaft 39, so that the valve operation arm 38b,
The spool 43a is operated by the connection of the rod 44 and the valve operating plate 43, and the flow of the pressure oil is switched so that the piston rod 23 of the machine vertical hydraulic cylinder Av protrudes. As a result, the left and right front wheels 6.6 and the rear wheels 8.8 are simultaneously lowered, and the airframe moves upward. As the body rises, the ridge surface grounding body 38 rotates downward by the spring 45, and the spool 43a is
When the vehicle reaches the neutral position that blocks the flow of the pressure oil to v, the ascent of the aircraft stops. Conversely, when the ridge surface is lowered with respect to the fuselage, the ridge surface grounding body 38 is rotated downward by the spring 45 around the sensor-support shaft 39 by the spring 45, and the spool 43a is moved to the position of the body vertical hydraulic cylinder Av. The flow of the pressure oil is switched such that the piston rod 23 retreats.
As a result, the left and right front wheels 6.6 and the rear wheels 8.8 are simultaneously raised, and the body is moved downward. As the body descends, the ridge surface grounding body 38 is pushed up by the ridge surface and rotates upward, and the spool 43a is in the neutral position where the flow of the pressure oil to the aircraft vertical hydraulic cylinder Av is blocked. When the aircraft descends, the descent stops. In this way, even if the height of the ridge fluctuates, the vertical position of the aircraft with respect to the ridge, that is, the planting position of the transplanting device 15 from the ridge (for example, the lowest point of the planting operation trajectory) is determined. Since the seedling can be maintained at a predetermined position, the planting depth of the seedling can be maintained and controlled at a predetermined depth. still,
Valve operating plate 43 of hydraulic valve 43 for vertical movement
Is connected to a wire 46 connected to the body vertical lever L, and the lever L can be used to manually move the body up and down to an arbitrary height. Further, by adjusting the tension of the spring 45, it is possible to adjust the sensitivity of the machine vertical control corresponding to the hardness of the soil on the ridge. Spring 4
5 is connected to the sensitivity adjusting lever Lp by a wire 45a. When the soil is soft, the spring 45 is loosened to reduce the pulling force. When the soil is hard, the spring 4 is used.
5 may be operated to increase the pulling force.

The operating hydraulic circuit of the hydraulic cylinders Av and Ar is as shown in FIG. Here, 46 is a hydraulic pump, 47 is a diversion valve, 48 and 49 are relief valves, T
Is a hydraulic tank. Hereinafter, the configuration shown in FIGS. 7 to 10 will be described. The pressure-reducing device 20 has a base of the support frame 20b shown in FIG. 9, and is provided so as to be able to swing up and down (pitching) and to swing right and left (rolling) with respect to the body. That is, a rolling support cylinder 50 whose axis is oriented in the front-rear direction is fixed to a bracket 3c 'fixed to the lower side of the horizontal frame 3c of the fuselage.
Are rollingly engaged. In addition, the swing connection tool 5
Reference numeral 1 denotes a pitching connection cylinder 51b integrally fixed to the rolling connection shaft 51a in the front-rear direction so as to cross in the left-right direction, and the pitching connection shaft 52 is rotatably engaged with the pitching connection cylinder 51b. ing. At both ends of the pitching connection shaft 52, connection tubes 53 are provided with spring pins 5.
3a and 53a are integrally connected. The connecting cylinder 5
The bases of the left and right mounting portions a, a of the support frame 20b on which the pressure reducing cylinders 20a, 20a are mounted on the three, 53 are engaged and integrally connected by bolts 53b, 53b. Thus, the support frame 20b is supported so as to swing up and down and roll left and right. On the other hand, the compression cylinder 20a
Reference numeral 20a denotes a wheel-shaped wide cylinder, and the support frame 20b
The support shaft 54 fixed to the support members 54 fixed to the left and right of the
a and 54a so as to freely rotate.

The suppression pressure of the pressure-reducing cylinders 20a, 20a is as follows:
Support frame 20 to which the pressure reduction cylinders 20a are attached
A pressure-reducing spring 55 urges a central portion of a connecting portion c for connecting the rear ends of the right and left mounting portions a, a to each other. The spring support shaft 55a supporting the compression spring 55 has a horizontal shaft 5 whose upper end is supported by a frame 5a fixed to the rear end of the transplantation portion transmission frame 5.
5b, and the lower side freely passes through a spring receiving member 20b 'fixed to the center of the support frame 20b,
A stopper 55c is attached to a lower end of the support frame 20b, which restricts the rotation of the support frame 20b, which rotates downward when the body moves upward, at a predetermined position.

The pressure reduction adjusting mechanism for adjusting the pressure reduction of the pressure reduction cylinders 20a, 20a is a main adjusting mechanism. A mechanism is provided to adjust the pressure by adjusting the pressure up and down.
Np is a bolt knob for fixing the pressure reduction adjusting device 55d to the spring support shaft 55a, and is an operation tool for adjusting the pressure reduction. Further, as a mechanism for finely adjusting the pressure reduction, a mechanism for finely adjusting the pressure reduction by adjusting a pressure reduction fine adjustment spring 56 connected to the pressure reduction adjustment arm 52a fixed to the pitching connection shaft 52 is provided. . The spring constant (elastic coefficient) of this pressure-reducing fine adjustment spring 56
Is set smaller than the compression spring 55.
In addition, the pressure control fine adjustment spring 56 includes a wire 56a.
The sensitivity adjustment lever Lp is also connected to the sensitivity adjustment lever Lp through a, so that the sensitivity adjustment lever Lp also serves as an operation tool for finely adjusting the pressure reduction, and the sensitivity adjustment of the machine vertical control corresponding to the hardness of the soil on the ridge surface. The structure is such that the pressure reduction of the pressure reduction device 20 can be adjusted in conjunction with the operation. Accordingly, the fine adjustment spring 56 is relaxed when the soil is soft, and is pulled when the soil is hard, so that the ridge surface is not crushed or the compression is insufficient. In addition, the pressure control arm 52a
Is fixed to the pitching connection cylinder 52.
1b, the arm 52a is inserted into the lower cutout 51c of the pitching connecting cylinder 51b.
When the arm 52a is inserted to the center of the connecting cylinder 51b, the connecting shaft 5 is moved along the pitching guide cutout 51d.
2 can be engaged by rotating.

As described above, the pressure-reducing device 20 supports the pressure-reducing cylinders 20a and 20a on the ridge surface and rolls while contacting the ground, and supports even if the vertical position of the ridge surface with respect to the machine body temporarily changes. The frame 20b swings up and down so as to always contact the ground. In addition, since the support frame 20b rolls around the rolling connection shaft 51a, the two left and right pressure reduction cylinders 20a always contact the ridge surface.

The groove forming device 19 includes a groove forming disk 19a.
19a is rotatably supported by support members 57 attached to the support frame 20b with support shafts 56a. As a result, the grooved disks 19a
The squeezing device 20 moves up and down with the vertical swing, and also rolls with the left and right rolling motion of the squeezing device 20. Therefore, the grooved disk 19a is always in
-Since 19a and the pressure reduction cylinders 20a move up and down with the pressure reduction cylinders 20a, the groove depth by the groove generation device 19 and the amount of soil covered by the pressure reduction device and the pressure reduction change in proportion to follow the change in the depth of the groove. As a result, the amount of soil cover and repression will change. When the support members 57 of the grooved disks 19a are attached to the support members 54 of the pressure-reducing cylinders 20a, the difference between the vertical swing amounts of the grooved disks 19a becomes smaller. Further, the groove forming body of the groove forming device 19 is not limited to the structure like the groove forming disks 19a.
