Next, the case where the seedling transplanting operation is performed by the above-mentioned walking type vegetable seedling transplanter will be described. The right and left crawler traveling devices 13 of the seedling transplanter move the ridge C of the field where the multi-film A is laid. The airframe is set so as to straddle it, and the left and right rotating roll body 150 is brought into contact with the multi-film A on the left and right inclined surfaces of the ridge C at a slightly forward side of the airframe of the right and left crawler traveling device 13, and After the pot-shaped vegetable seedlings grown in a paper-made seedling incubator vertically and horizontally arranged at predetermined intervals are placed and accommodated, the engine 2 is started and the throttle lever 59 is turned from the idling speed. When the seedling planting operation speed is increased, the power of the engine 2 is transmitted to each rotating part via the centrifugal clutch in the clutch case 3, and the left-right rotating roll 150 is a multi-film A on the left-right inclined surface of the ridge C
When the left and right crawler traveling devices 13 are driven to rotate, the multi-film A may be broken by rotating the multi-film A while holding the multi-film A in a state where the multi-film A is pressed. In the prevented state, the body is favorably propelled by the rotation of the left and right driving crawlers 13.

At this time, when the ignition switch is turned on, the flame is blown out from the nozzle to heat the opening device 50 to a high temperature, and the planting clutch lever 57 is operated to set the clutch to the on position. Since the table 28 is reciprocally oscillated in the left-right direction via the left-right driving mechanism, the bottom surface and the front end of the tip of the seedling located at the rear end are received by the seedling receiving frame 35 and the seedling receiving rod 36, respectively. The seedling is moved left and right in the state, and the seedling is fed out to the seedling removal port 35a, and is sequentially grasped by the seedling nails 40a and 40b of the transplanting device 39 that draws the seedling locus P. On the other hand, the heated opening device 50 forms a seedling planting hole on the upper surface of the ridge C while making a hole at the seedling planting position of the multi-film A.

The left and right crawler traveling devices 13 are automatically adjusted up and down by the detection of the upper surface of the ridge C by the sensor 192, so that the seedlings are always planted on the ridge C at a predetermined planting depth H. Then, for example, when planting three seedlings on the upper surface of the ridge C, first, the left and right crawler movement operation lever 6
0a and 60b are operated by the same amount to move the left and right crawler support frames 11 left and right to move the left and right crawler traveling device 1
The position of the crawler is adjusted so that 3.13 is located in the ridge and the planting position is at the center of the ridge. Running in this state, a seedling is planted at the center of the ridge to form a row of seedlings. Then, the left and right crawler moving operation levers 60a and 60b are operated to adjust the position of the crawler so that the left and right crawler traveling devices 13 and 13 are located in the ridges and the planting position is at the end of the ridge. Plant seedlings on both sides of the row.

When the operation of the seedling table 28, the transplanting device 39, and the hole opening device 50 is to be checked by stopping the advancement of the airframe, the left and right side clutch levers 56 are operated with the side clutch disengaged. By increasing the rotation speed of the engine 2 with the lever 59 and connecting the centrifugal clutch to the clutching operation of the planting clutch lever 57, only the seedling mounting table 28, the transplanting device 39, and the opening device 50 can be operated. it can.

Next, a ridge C formed on an inclined surface in a mountainous area
Next, a transplant operation when the multi-film A is laid will be described. Since the ridge C formed on the inclined surface in the mountainous area has the ridge D1 on the mountain side higher than the ridge D2 on the valley, the left and right crawler traveling devices 13 of the seedling planter are connected to the multi-film. When the airframe is set so as to straddle the ridge C on which A is laid (FIG. 10), the left / right tilt control valve 20b switches in conjunction with the movement of the pendulum 200 for detecting the right / left tilt, and the rolling cylinder 27 operates to move the airframe. The right crawler traveling device 13 in the ridge groove D1 on the mountain side is moved upward to be in a lying state almost horizontal as shown in FIG. 11, and the left crawler traveling device in the ridge groove D2 on the valley side is controlled to be horizontal left and right. 13 moves downward and rises as shown in FIG.

Then, since the right crawler traveling device 13 in the lying state which is almost horizontal as shown in FIG. 11 abuts on the ridge C substantially horizontally, it rotates at the peripheral speed of the pitch circle of the driven wheel 77. It proceeds at the rotation speed of the right crawler 78. on the other hand,
The left crawler traveling device 13 in the standing state as shown in FIG.
Abuts on the lug 13a having a diameter larger than the pitch circle of the driven wheel 77, so that the lug 13a advances at a peripheral speed (rotation speed). That is, the right crawler traveling device 1 of the ridge D1 on the mountain side
The forward speed of the left crawler traveling device 13 in the ridge groove D2 on the valley side is slightly faster than the forward speed of No. 3.

Therefore, in the transplanting operation on such a slope, conventionally, when the airframe is advanced, the airframe tends to move to the valley side (lower side), so that it is difficult to transplant the seedlings. According to the machine, as described above, the left crawler traveling device 13 in the valley-side ridge D2 is automatically moved faster than the right crawler traveling device 13 in the ridge-side ridge D1.
Is slightly faster, so the aircraft is on the mountain side (higher side)
Since the driving force to move the airplane works, it is easy to appropriately and forwardly move the machine body on the slope, and the seedling transplanting operation can be performed efficiently and easily.

Finally, a second embodiment will be described with reference to FIG. This second embodiment is different from the first embodiment in that the left and right front wheels 1
4 is provided with a left and right front crawler traveling device 100. The front left and right crawler traveling device 100 has exactly the same configuration as the left and right crawler traveling device 13 and has a left and right driving wheel 76 mounted so as to rotate integrally with the left and right crawler driving shaft 1a. The left front crawler traveling device 100 and the left crawler traveling device 13 and the right front crawler traveling device 100 and the right crawler traveling device 13 are linked so as to move up and down by the same amount.

As described above, when the front left and right front crawler traveling device 100 is provided in place of the front left and right wheels 14, the propulsive force is significantly increased, and the aircraft can be properly advanced even on a slope such as a mountainous area or a soft field. Transplanting of seedlings can be performed easily.
