A walking rice transplanter, which is an example of a walking rice paddy work machine, performs elevation control to maintain the planting depth of planted seedlings, and vertical displacement of the machine body is detected by the ground float. In addition, some types of walk-behind rice transplanters are equipped with a fertilization device that feeds fertilizer into the vicinity of planted seedlings.
A groove cutting plate and a groove cutting device for making grooves in the mud surface into which fertilizer is fed are attached to a ground float as disclosed in, for example, Japanese Utility Model Application Publication No. 124418/1983.

作用の安定化を図つている機種がある。 In recent years, the groove cutting board and groove maker have been installed on the lower surface of the grounding float or on the lower surface of an overhang extending from the grounding float, and the grooves are created using the grooving plate and the groove maker while leveling the ground. There are models that are designed to stabilize the groove-making action.

The furrower is connected to a fertilizer applicator via a vinyl hose or the like, and the fertilizer etc. delivered from the fertilizer applicator passes through the vinyl hose and is sent from the furrower to the groove on the mud surface. Therefore, if the groove cutter and groove cutter are attached to the ground float as described above, even if the vinyl hose has sufficient flexibility, the vertical movement of the ground float will affect the vinyl hose. The movement is sluggish and precise lifting and lowering control cannot be expected.
ここで本考案は前述の点に着目して、作溝器に

御に支障が生じないような構造を得ることを目的
としている。 Here, the present invention focuses on the above-mentioned points, and aims to obtain a structure that does not cause any trouble in lifting and lowering control while maintaining a stable state of groove-forming action by the groove-forming device.

The feature of the present invention is that, in the above-mentioned walking type paddy field working machine, the groove cutter and the groove cutting plate are attached to the fixed part on the body side, and a slit is provided in the ground float, so that the groove cutter and the groove cutting plate are attached to the The action and effects of the slit projecting into the mud surface are as follows.

With the configuration as described above, the connection relationship between the groove cutting plate and the groove cutting device and the grounding float can be canceled while the groove cutting device and the groove cutting plate are located on the lower surface of the grounding float. As a result, the grounding float is not affected by the vinyl hose connected to the groove cutting board or groover, so the grounding float faithfully follows the mud surface and sensitively detects the vertical movement of the aircraft. It will be possible.

ことができた。
As described above, by positioning the groove cutter and the groove cutting plate on the lower surface of the grounding float to stabilize the groove-making action, and eliminating the structure that would hinder the vertical movement of the grounding float, the function of raising and lowering control is achieved. We were able to prevent the decline.
