Description

[Detailed description of the invention] The present invention supports the aircraft through the cooperation of a propulsion wheel provided at one location in the front and back direction when viewed from the side, and a sliding grounding body that touches the hard surface at a position in front or behind the wheel. The purpose of this rice transplanter is to provide auxiliary wheels for road running in a form that is convenient for practical use. It is sturdy enough to be installed.

The above-mentioned rice transplanter exists on hard ground by supporting the machine body through the cooperation of the sliding ground body and propulsion wheels, which can have a large radius of curvature and set a large length of ground contact in the front and rear directions. This is to prevent the sliding ground body 5 from frequently moving up and down due to small irregularities, thereby suppressing as much as possible the occurrence of vibrations caused by the body swinging up and down around the wheel axis. Moreover, by adjusting the vertical swing of the grounding body according to the depth from the mud surface to the hardbed, the attitude of the aircraft is maintained properly regardless of changes in the depth of the hardbed, resulting in a stable planting posture. However, it is possible to easily move the grounding body up and down, which requires a large operating force, using a drive mechanism, but it has the following problems.

In other words, conventionally, the propulsion wheels and the sliding grounding body work together to support the aircraft even when traveling on the road, but in this case, unlike the hard ground in the field, there is a large amount of foreign matter such as stones. There is a problem in that the grounding body tends to wear out quickly due to sliding contact with the road surface.

The present invention was made keeping in mind the above actual situation,
In a rice transplanter having an official structure, an auxiliary wheel is removably attached to a part of the grounding body that floats up from the hardboard when the grounding body is operated close to the lowering limit, with the auxiliary wheel floating from the hardboard. In this state, by raising the grounding body over a small range, the auxiliary wheels and the propulsion wheels can work together to support the aircraft.

In other words, by providing auxiliary wheels, the auxiliary wheels 8 and the propulsion wheels work together to support the aircraft when traveling on the road, in an attempt to resolve the government issue. In a state where the body is operated close to the lowering limit,
An auxiliary wheel is removably attached to the ground body part that is floating above the ground, and by raising the ground body within a small range when the auxiliary wheel is attached, the propulsion wheel and the auxiliary wheel can be connected to each other. Since it is intended to show the aircraft support state, it is possible to easily attach and detach the auxiliary wheels to the ground body by avoiding contact with the ground.
Moreover, when the auxiliary wheels are on the ground, by adjusting the vertical swing of the grounding body, it is possible to swing the aircraft back and forth around the axis of the propulsion vehicle body to change the aircraft attitude, for example. It can be conveniently used to keep the aircraft in a horizontal position when traveling on slopes, etc.

This makes it possible to effectively use the existing grounding body and attach auxiliary wheels for road running in a form that is convenient for practical use, resulting in a rice transplanter with great practical advantages. .

Embodiments of the present invention will be described in detail below based on illustrative drawings.

Figure 1 shows a side view of the riding rice transplanter, and Figure 2 shows its plan view, showing the front engine 1, rear rice transplanting device 2, and driver's seat 3.
When viewed from the side, the aircraft body is equipped with a propulsion wheel 4 that can be operated to change the orientation provided at one location in the front and back direction, and a pair of left and right sliding grounding bodies 5, 5 that are in contact with a hard surface behind this wheel 4. It is configured to advance while being supported by cooperation, and to plant a plurality of rows of seedlings in the rear rice planting device 2 as it advances.

The left and right grounding bodies 5, 5 extend from a horizontal shaft 7 which is rotated around the axis by a hydraulic cylinder 6, and are configured to be vertically oscillated and adjusted by the operation of the hydraulic cylinder 6. There is.

In addition, when the left and right grounding bodies 5, 5 are operated close to the lowering limit, the auxiliary wheels 8, 8 can be attached to and detached from the grounding body portion floating from the hard plate, as shown in FIG. By raising the grounding body 5°5 by a small range when the auxiliary wheels 8, 8 are attached,
As shown in FIG. 4, the auxiliary wheels 8, 8 and the propulsion wheels 4 cooperate to support the aircraft body.

In addition, 9 and 9 in the figure are auxiliary wheel attachment cylindrical bodies fixed to the grounding bodies 5 and 5.

(See Fig. 5) Furthermore, when the auxiliary wheels 8, 8 are not in use, they are attached to the swinging bases of the grounding bodies 5, 5 in an inverted position, and the swinging bases also have tubes for mounting the auxiliary wheels. Shape 1
0.10 is fixed.

Incidentally, the present invention can also be implemented in the case where a sliding grounding body 5 that is in contact with a hard plate is provided at a position in front of the propulsion wheel 4.

Further, the present invention can also be applied to a traveling rice transplanter.
