Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is towed by a traveling body traveling in a plant groove,
The present invention relates to a forward direction control device in a long onion transplanter that shifts the planting groove walls on the left and right sides with respect to the forward moving direction and plants seedlings on the groove bottom along the planting groove walls.

[Prior Art] As is well known, long onions are cultivated by excavating planting grooves in parallel rows at equal intervals in a field and planting seedlings vertically along one sunny planting wall. A long onion transplanter that satisfies this planting condition is, for example, a "long onion transplanter" disclosed in Japanese Patent Laid-Open No. 62-228205, which is offset to the left and right plant groove walls with respect to the forward direction. It is well known that seedlings are planted while excavating the groove bottom along the groove wall.
Then, the above-mentioned known long onion transplanter is rotated to the opposite side from the planting side generated around the connecting point at the rear center of the traveling machine body due to excavation resistance of the groove bottom, etc. In order to receive the moment and move forward in the direction of the planting groove, a traveling stabilizer that slides on the groove wall on the opposite side to the planting side is provided at the rear part so that the lateral position can be changed.

Even if the planting groove meanders,
To ensure that the transplanter runs along the planting groove,
In Japanese Utility Model Laid-Open No. 61-173212, a "running guide device for transplanter" is proposed.

This invention provides a pair of left and right guide rollers on the front part of the transplanting machine, and forms both outer side surfaces of the guide roller on the Narai guide surfaces that are in rolling contact with both side walls of the planting groove. It is configured to run along the planting groove by the surface. Further, the guide wheels are arranged with the toe-in so that the outer side surface is substantially matched with the inclination of both side walls of the planting groove and the front width is narrowed.

[Problems to be solved by the invention] The conventional long onion transplanter is used in the field of soil that is hard to collapse.
Since the traveling stabilizer can keep the forward direction in the planting groove direction, to plant seedlings upright along the planting groove wall,
There was no problem. However, recently, long onions have been cultivated even in fields that are easily broken like sandy soil. As a result, in such a field, when the above-mentioned moment is applied to the traveling stabilizer, the wall of the planting groove collapses and the rear part of the long onion transplanter moves to the side opposite to the planting side, and the long onion transplanter moves to the center of the rear part. The front part of the traveling body fixed to the is directed toward the groove wall on the planting side. Therefore, the traveling machine body has been slantingly advanced toward the groove wall on the planting side, which causes a problem that seedlings cannot be planted upright along the groove wall.

Further, in the one disclosed in Japanese Utility Model Laid-Open No. 61-173212, both outer side surfaces of the guide wheel are made to substantially coincide with the inclination of both side walls of the planting groove. Therefore, since the structure is unique to the groove width and the inclination of both side walls, there is a problem that the guiding action becomes uncertain when the groove shape is changed.

The present invention advances the traveling machine body along the planting groove direction regardless of the width of the planting groove and the slopes of both side walls even in the field of fragile soil, and the long onion transplanter plant seedlings along the planting groove wall. It is an object to provide an advancing direction control device which makes it possible to be planted.

[Means for Solving the Problems] In order to achieve the above object, in the present invention, a bifurcated bracket is attached to the front center of a traveling machine body tow a long onion transplanter, and an L-shaped shaft is attached to the bifurcated bracket. Is attached to the upper end of the yoke so as to be rotatable about the horizontal axis, and the front end is projected forward so that the height can be adjusted, and a wheel yoke is attached to the front end of the wheel so as to be rotatable about the vertical axis. On the inside, a flange wheel with a concentric circular flange protruding upright in the center of the outer periphery of the rim was provided so that it could rotatably support the bottom of the planting groove and turn to the left and right with respect to the forward direction of the traveling machine body. It is a thing.

Furthermore, in order to hold the flange wheel in a raised state during movement in the field or turning at the end of the grooving, an L-shaped shaft locking device that releasably locks the L-shaped shaft inverted around the horizontal axis, It was attached above the bifurcated bracket via the front portion of the traveling machine body.

[Operation] Since the present invention is configured as described above, when the flange wheel is held by hand and the L-shaped shaft is turned around the horizontal axis until it is inverted, the bifurcated bracket causes the wheel yoke to pass through the horizontal shaft and the L-shaped shaft. And the flange wheel are supported above the front part of the traveling body (first
(See the chain lines in the figure). The L-shaped shaft locking device locks the L-shaped shaft inverted above the bifurcated bracket as described above, stops the downward rotation thereof, and holds the L-shaped shaft, the flange wheel, and the wheel yoke in the inverted state.

At the time of planting seedlings, the L-shaped shaft holding the flange wheel as described above is released from the L-shaped shaft locking tool and pivoted downward about the horizontal axis, so that the flange wheel comes into contact with the planting groove bottom. Therefore, when the flange of the flange wheel is straightened and the traveling vehicle is moved straight, the rim of the flange wheel rolls on the groove bottom, the lower peripheral part of the flange penetrates the groove bottom, and the flange becomes a kind of rudder. The flange wheel goes straight on the bottom of the groove without swinging to the left or right. At this time, the L-shaped shaft adjusts the height of the front end of the L-shaped shaft to prevent the flange wheel from sinking and to provide an appropriate penetration depth of the flange. On the other hand, the traveling stabilizer moves the long onion transplanter straight while sliding on the groove wall on the side opposite to the planting side.
That is, the flange wheel and the traveling stabilizer jointly allow the long green onion transplanter and the traveling machine body to go straight, so that the seedlings can be planted upright along the planting groove wall on the side of one-side shifting.

As described above, when the planting groove wall is broken by the sliding of the traveling stabilizer, the flange of the flange wheel is turned from the straight traveling direction to the direction opposite to the planting side at an appropriate angle. Then, the flange wheel tries to advance diagonally in the direction opposite to the planting side while the flange penetrates the groove bottom, and as described above, the traveling vehicle body that attempts to diagonally advance toward the groove wall on the planting side, Return straight. Then, the appropriate angle for turning the flange wheel described above may be adjusted so that the traveling machine body advances straight while the traveling machine body advances.

Even in fields where it was not possible, the traveling aircraft can go straight. Therefore, even in such a field, the long green onion transplanter can perform planting suitable for long green cultivation. Also, the L-shaped shaft to which the flange wheel is attached can adjust the height of the front end, so if the bottom of the groove is soft and the rim sinks, and the running resistance increases, the L
If the front end of the shaped shaft is raised, the flange wheel is raised, so that the above-mentioned problems can be eliminated. Further, since the flange wheels move the traveling vehicle body straight, the traveling vehicle body can move forward even if it is released. Therefore, when planting long onion seedlings, the seedling supplier can also plant the seedlings as a driver, and the number of workers can be economically planted.

Further, by providing the L-shaped shaft locking device, the flange wheel can be easily held in the inverted state, and the traveling machine body and the long onion transplanter can be moved and circulated in the field without any trouble. The device of the present invention has a structure in which the entire device can be attached and detached by attaching and detaching the bifurcated bracket to the front part of the traveling machine body.
