Claims (8)

It is equipped with a float body that floats on water and a screw that protrudes underwater from the lower surface of the float body, and A weed control device for a paddy field that floats on water by the above-mentioned float body and, while the draft at the bottom of the above-mentioned screw does not reach the bottom of the water, stirs the water in the paddy field by pushing with the above-mentioned screw to wind up mud and generate a mud film, and prevents or suppresses the growth of weeds by the mud film. A water-use weeding device characterized by having a draft adjustment mechanism that raises and lowers the draft position of the water-use weeding device.
In claim 1, the draft adjustment mechanism is configured to adjust the relative height dimension of the float body and the screw, for a water-use weeding device.
A water-use weeding device according to claim 1 or 2, wherein the draft adjustment mechanism is configured to adjust the buoyancy of the float body by adjusting the capacity by filling the float body with air.
In claim 1 or 2, the float body is composed of a plurality of divided bodies, and The above draft adjustment mechanism is a water-use weeding device configured to adjust the buoyancy of the entire float body by increasing or decreasing the number of the float bodies divided into multiple parts.
A weeding device for paddy fields according to claim 1 or 2, wherein the float body is arranged to surround the screw, thereby forming a guard surface around the screw for knocking down rice plants.
A water-use weeding device according to claim 5, wherein the float body is provided with a bending shape portion formed on the periphery of the guard surface, which is formed to expand in width from the lower to the upper direction of the float body when viewed in a planar view.
A method for weeding a rice paddy, characterized by weeding the rice paddy using a weeding device for a rice paddy described in claim 1 or 2.
This is a method of cultivating crops in a paddy field where seedlings are planted and filled with water, and A method for preparing a cultivated crop characterized by including a weeding process that operates a water-use weeding device described in claim 1 or 2.

Description
