Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rice transplanter in which a spare seedling stand is provided on a passenger traveling body equipped with a seedling planting device at the rear.

[Conventional technology]

In the rice transplanter mentioned above, conventionally, for example,
As shown in Publication No. 59-175807, when replenishing the reserve seedling rack with seedlings, the seedling planting device is installed so that the seedlings can be easily supplied from the ridge to the reserve seedling rack, and from the reserve seedling rack. When replenishing seedlings to the seedling rack in preparation for the operation, the spare seedling rack can be freely swung around the vertical axis near the center of the traveling machine so that seedlings can be easily supplied from the driving section to the seedling rack. When replenishing seedlings from the ridge to the spare seedling stand, the swinging arm is swung to position the spare seedling stand towards the front of the machine. When replenishing seedlings from the seedling stand to the seedling stand, move the spare seedling stand closer to the seedling stand at the rear of the machine.
The swing arm was made to swing.

[Problem that the invention attempts to solve]

However, as mentioned above, since the spare seedling stand is attached to the swing arm in a cantilevered manner, for example, when traveling with the spare seedling stand positioned toward the front of the machine, the center of gravity of the machine moves forward greatly. As mentioned earlier, depending on the position of the spare seedling stand, the weight balance between the front and rear of the machine would be greatly affected.

An object of the present invention is to suppress as much as possible the deterioration of the weight balance due to the position of the preliminary seedling stand.

[Means for solving problems]

The characteristic configuration of the present invention is that a horizontal support frame located above a passenger traveling vehicle equipped with a seedling planting device at the rear is connected to a supporting member erected from the traveling vehicle body at the center thereof, and Spare seedling stands are attached to each end of the support frame, and when one of the spare seedling stands is located on the front side of the machine, the other spare seedling stand is located on the rear side of the machine. Another feature is that the support frame is supported so as to be able to swing freely around the vertical axis at a height that bypasses the upper part of the driving section.

[Function] By connecting the center part of the support frame, which has spare seedling stands attached to each end, to the supporting member erected from the traveling machine, both spare seedling stands can be placed regardless of the positions of both spare seedling stands. Since the entire weight of the seedling stand is always applied to the support member, the movement of the actual center of gravity, which is the combination of the center of gravity of both of these standby stands and the center of gravity of the traveling machine, is calculated by adjusting the movement of the standby stand attached in a cantilevered manner as in the past. This can be suppressed to a lesser extent than when the platform is located at the front or rear side of the traveling aircraft, or it can be completely eliminated by aligning the position of the support member with the center of gravity of the aircraft. .

Also, if one of the spare seedling stands is located on the front side of the machine, the other spare seedling stand is located on the rear side of the machine. While an auxiliary worker supplies seedlings from the ridge, a worker in the operating section can also supply seedlings from a spare seedling platform located at the rear of the machine to the seedling platform of the seedling planting device.

[Effect of idea]

Therefore, no matter what rotational swing position the two spare seedling stands are located, the center of gravity of the two spare seedling stands will not move toward the front side or the rear side of the machine body with respect to the support member. The movement of the actual center of gravity, which is the combination of the center of gravity of both spare seedling stands and the center of gravity of the traveling machine, can be reduced compared to conventional methods, or depending on the position of the support member, it can be completely eliminated, thereby improving the weight balance. Now I can work in good conditions.

In addition, the two spare seedling racks are positioned one after the other, and as described above, the work of replenishing seedlings from the ridge to the spare seedling rack and the work of replenishing seedlings from the spare seedling rack to the seedling rack of the seedling planting device are performed simultaneously. This makes it possible to carry out seedling replenishment work even more efficiently.

〔Example〕

As shown in FIGS. 1 and 2, an engine E is mounted on the front part of the traveling aircraft, a driving section S equipped with a steering handle H and a driver's seat 1 is provided in the center of the traveling aircraft, and A seedling planting device A, which is equipped with a rotary body 2 having a plurality of seedling planting claws on the periphery, a seedling platform 3 that can slide back and forth from side to side, and a grounding float 4, is attached via a link mechanism 5. A riding rice transplanter is constructed by connecting them so that they can be raised and lowered.

A cylindrical member 7 is fixed to the rear upper part of the engine bonnet 6 that covers the engine E, at the center in the width direction of the fuselage, and a rod-shaped support member 8 extending in the vertical direction of the fuselage is rotatably fitted into the cylindrical member 7. A horizontal support frame 9 located above the traveling machine body is connected to the upper end of the support member 8 at the center thereof, and a plurality of upper and lower seedling placement portions 10a are provided at each end of the support frame 9. A spare seedling stand 10 is attached so that work can be carried out with a well-balanced weight.

Then, by rotating the support member 8, the support frame 9 is pivoted around the vertical axis X at a height that bypasses the upper part of the driving section S,
One of the preliminary seedling resting stands 10, 10 is located on the front side of the machine body, and the other spare seedling resting stand 10 is located on the rear side of the machine body, so that it is located on the front side of the machine body. While an auxiliary worker replenishes seedlings from the ridge to the preliminary seedling platform 10, a worker in the driving section S loads the seedlings from the preliminary seedling platform 10 located at the rear of the machine to the seedling platform 3 of the seedling planting device A. We are making it possible to replenish the supply of

When supplying seedlings from the preliminary seedling tray 10 to the seedling tray 3, as described above, one of the preliminary seedling trays 10
on the front side of the aircraft, and the other spare seedling stand 10
However, during seedling planting work, the preliminary seedling stands 10, 10 are located on both sides of the machine, as shown by the imaginary lines in Fig. 2, so that the front visibility is improved. is maintained in good condition.

A bolt 1 with a knob is fixed to the cylinder member 7 to prevent rotation of the support member 8.
1 is attached, and the spare seedling stand 10, 10
After locating the holder at a predetermined position, the preliminary seedling stands 10, 10 can be fixed at that position by tightening the bolt 11.

Incidentally, numerals 12 shown in FIG. 2 are steps located on both lateral sides of the engine bonnet 6, and are used when stepping down from the drive section S to the ridge or transferring from the ridge to the drive section S.

[Another example]

In the embodiment described above, the support member 8 was rotated by manual force, but it may be rotated by an actuator such as an electric motor.

Further, in the above embodiment, the support member 8 is erected on the front side of the body, but it may be erected on the rear side of the body, and the support member 8 may be erected at any position.

Further, in the above embodiment, the positions of the preliminary seedling stands 10, 10 are changed by rotating the support member 8, but the support member 8 is fixed to the traveling body, and the upper end of the support member 8 is changed. A support frame 9 may be rotatably attached to the support frame 9, and the positions of the preliminary seedling stands 10, 10 may be changed by rotating the support frame 9.
