Description

[Detailed description of the invention] The present invention relates to a rice transplanter in which a seedling planting device is connected to a vehicle body so as to be able to roll freely, and the seedling planting device is provided with a support float that restricts the rolling. The object of the present invention is to enable the planting work to be carried out well in the ridge area while maintaining the desired planting posture.

More specifically, the above rice transplanter is designed to stabilize the planting posture by supporting the seedling planting device in an appropriate posture with respect to the mud surface using floats even if the vehicle body rolls due to unevenness existing on the hard platen. However, since the mud near the ridges tends to become stiffer as it approaches the ridges, when planting at the ridges, the float parts located far from the ridges sink deeper into the mud. As a result, there is a problem in that the attitude of the seedling planting device towards the mud surface deviates from the proper attitude and the planting attitude deviates from the desired attitude.The present invention aims to solve these problems. It is something.

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

As shown in Figs. 1 and 2, a pair of left and right front wheels 1゜1 that can be operated to change the direction and can be driven and rotated, a pair of left and right spoke large diameter rear wheels 2a*2a that can be driven and rotated, these rear wheels At the rear of the vehicle body, which is equipped with a pair of left and right spoke small-diameter rear wheels 2b, 2b, which can be driven and rotated, located on the inner side of 2at2a, and a driver's seat 3, etc., there is a parallel circuit that can be raised and lowered by a hydraulic cylinder 4. A slanted seedling stand 6 is connected to the link mechanism 5 and reciprocated horizontally with a constant stroke, and one seedling is placed one seedling at a time from the lower end of each of the six mat-shaped seedlings placed horizontally on this seedling stand 6. A seedling planting device equipped with six planting claws 7, etc., which take out and plant seedlings one by one, is arranged in a downward mound with respect to the rear end of the parallel link mechanism 5. The device is connected to the seedling planting device in a rolling manner via a pair of swing links 9, 9 (see FIG. 3), and is further connected to the seedling planting device.
The three floats 10 that regulate the rolling are installed in a horizontally lined state and can swing vertically around a fulcrum P near the rear end, so that the floats 10... In addition, despite the rolling of the vehicle body due to the unevenness of the hard surface, the seedling planting device was supported in an appropriate posture on the mud surface by the float 10. The structure is configured to stabilize the posture, and the seedling planting device is further configured to be raised and lowered relative to the vehicle body in accordance with the depth from the mud surface to the hard surface to stabilize the planting depth. It is.

A pair of left and right rod-shaped bodies 11, 11 extending in the front-rear direction are attached to the seedling planting device in a state in which they are positioned on both sides of the device and in a posture in which the front end is positioned below the seedling-planting device. 1
1. The upper surface of 11 is pressed downward by contact with the ridge side wall as the aircraft advances.
It is configured in T.

Therefore, during planting work at the ridge edge, as shown in FIG. 3, by moving the rod-shaped body 11 while slidingly contacting the ridge side wall, the mud at the ridge edge approaches the ridge. Even if the mud tends to be as hard as the mud, the part of the seedling planting device adjacent to the ridge is pressed downward to sink all the floats 10 into the mud at the same depth, that is, when planting seedlings. The attachment device can be supported by the float 10 in an appropriate posture relative to the mud surface.

As shown in FIG. 4, the small diameter rear wheel 2b is configured by:
Notches 14 and 15 for axle insertion are formed in the ring-shaped circumferential grounding body 12 and the bub 13 bolted to the axle 18, and the bub 1 is formed in the notch portion of the grounding body 12.
Reinforcing bodies 16 and 17 that can swing open and close are attached to the notches 3, so that the rear wheel 2b can be attached to and detached from the axle 18 while being moved in a direction perpendicular to the axis.

Therefore, the work of attaching and detaching the small diameter wheel 2b as necessary,
This can be done easily and quickly without any special operation on the large diameter wheel 2a attached to the axle 18.

In the embodiment, the rod-shaped body 11 is exemplified as a ridge abutting tool, but the ridge abutting tool may also be configured using a plate or the like.

Further, the present invention can be applied not only to the riding type rice transplanter having the configuration described in the embodiment, but also to rice transplanters having other configurations.

In summary, the rice transplanter according to the present invention has an official structure, and the receiver located below the front throat is a ridge contact with a surface T so that it is pressed downward by contact with the ridge side wall as the machine advances. It is characterized in that the tool 11 is attached to the seedling planting devices 6, 7 in a state in which they are positioned laterally and outwardly of the seedling planting devices 6, 7.

That is, by moving the machine while sliding the ridge contact tool 11 against the ridge side wall during ridge work, even if the mud at the ridge area tends to get stiff as it approaches the ridge,
The part of the seedling planting devices 6, 7 near the ridge is pressed downward and the entire width direction of the float 10 is sunk into the mud at the same depth, that is, the seedling planting devices 6, 7 are pressed downward. By using the float 10, it is possible to bring about a state in which the float is supported in an appropriate posture on the mud surface, thereby solving the problem noted in the government,
It is now possible to perform planting work at the edge of the ridge while maintaining the desired planting posture.
