を設けた田植機に関する。[Detailed description of the invention] This invention allows the installation height of multiple floats to be changed at once by rotating the spindle, and the amount of descent of the seedling planting claw relative to the float can be easily adjusted. , and by leveling the ground where the wheels passed, multiple soils were placed side by side in the lateral direction of the machine to prevent mud near the seedling planting area from flowing into the depressions of the wheel tracks and disturbing the posture of the planted seedlings. The present invention relates to a rice transplanter in which a support shaft of a grounding float is horizontally suspended behind a wheel in a state where it can be freely rotated to change the mounting height of the float to the machine body, and a ground leveling tool is provided for the track of the wheel.

た。 In the above rice transplanter, conventionally,
As shown in the issue, the downward biasing force applied to the ground leveling tool was constant regardless of whether the float was up or down, so when the mud is hard, the pressing force may be insufficient and the ground may not be leveled sufficiently, or conversely, the ground leveling tool may not be sufficiently leveled when the mud is hard. When the mud was soft, the pressing force was too strong and the surface of the mud was sometimes disturbed.

用上に難点があり、改良の余地があつた。 In order to solve this problem, it was proposed in Utility Model Application Publication No. 119620/1983 to change the downward biasing force of the ground leveling plate in conjunction with the adjustment of the planting depth, but the structure was complicated and it was difficult to put into practice. There was room for improvement.

造簡単に得られるようにすることにある。 The purpose of this invention is to be able to change and adjust the pressing force of the ground leveling tool according to the hardness of the mud, and to do so accurately and without any special effort, and to make effective use of the original structure. The goal is to make modifications easier.

ある。 The characteristic configuration of the present invention is that, in the above-mentioned rice transplanter, the ground leveling tool is mounted on the spindle so that as the grounding float is lowered relative to the machine body by its rotation, the angle of elevation from the ground in the non-operating state becomes smaller. It's because I installed it.

きた。 In general, the harder the mud is, the greater the reaction force the seedling planting claw will have when it plunges into the mud, and the higher the height the aircraft will be pushed up when planting seedlings due to that reaction force.
The installation height of the float is adjusted higher so that the amount of descent of the seedling planting claw relative to the float is greater than when using soft mud soil. By extending it so that it changes as shown in the figure, just by changing the installation height of the float, the acting force of the ground leveling tool will automatically increase when the soil is hard, and increase when the soil is soft. This will definitely change to the decreasing side.
Therefore, the acting force of the ground leveling tool can be adjusted accurately according to the change in the hardness of the mud, without requiring any special effort, and in the direction of change in the hardness of the mud. Regardless of whether it is soft or hard, it is possible to work while leveling the ground well without disturbing the mud from the wheel marks, and it is also advantageous in terms of operation.
