(Prior Art) In paddy field working machines, for example, in-ground seeding machines for paddy rice cultivation, a sowing device is generally provided on a float that slides in the field, and the bottom surface of the float is equipped with a sowing device. A trencher is installed in front of the guideway, and a potter is installed at the rear. The rear earthen coverer is attached to a mounting plate extending rearward from the front part of the upper surface of the float.

By the way, the flat elastic body to which the soil coverr is attached is positioned to cover the drop guide port of the float from above, but this flat elastic body has a cutout above the drop guide port to allow mud to escape. Since the space is formed, even if soil is piled up above the drop guide port due to the trench-cutting and soil-covering action, the drop guide port will not be clogged with clods of soil.

By the way, since the soil coverr 15 is attached to a flat elastic body 17 and can be moved upward, even if the traveling body 1 heads up in a hard field, the soil coverr 15 will not dig into the field. It does not disturb the field scene. Furthermore, the flat elastic body 17 to which the soil coverr 15 is attached is positioned to cover the fall guide port 8 on the upper surface of the float 4, but the flat elastic body 17 has a notch 18 which is a space for mud release. Since this is formed, clods of soil and the like that rise from the drop guide port 8 of the float 4 due to trenching, soil cultivation, soil covering, etc., do not clog the area and are smoothly removed.

(Effects of the invention) As described above, the present invention provides a rice paddy working machine equipped with a powder delivery device on the float, in which a groove-making device is installed in front of the drop guide port provided on the float, and a groove-making device is installed in front of the drop guide port provided on the float. A soil cultivator is placed behind the vessel on one side across the groove path, and on the other side slightly behind it is a flat elastic body extending in a cantilevered manner from the top surface of the float toward the rear. A soil covering device was installed, and a notch was provided in the elastic body to form a mud relief space above the drop guide port of the float. Even if the soil piles up, the soil clods will not clog the falling guide port, allowing for smooth and proper sowing. Since it is installed,
The soil covering device itself has good ability to follow the field surface even when the aircraft posture changes, and especially when the aircraft heads up, the soil covering device can easily escape upwards, preventing it from penetrating deeply into the soil, and can prevent soil from being covered at the edges of ridges, etc. Even if the container comes into contact with an obstacle and external force is applied, the flat elastic body deforms more elastically, which prevents damage or deformation of the earthen covering device itself, ensuring good soil covering performance at all times. Not only can it be maintained in
Since the flat elastic body can be used as a mounting member for the earthen coverr, the number of parts can be reduced as much as possible, and the mounting structure for the earthencoverer can be simplified, which in turn can reduce the weight of the working part.
