BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scraping method for plowing a field after harvesting a grain culm to make a shallow scraping, a scraping planting method, and a scraping simultaneous planting machine.

[0002]

2. Description of the Related Art Conventionally, a method of plowing a field in which grain culms are harvested and scratching the entire tillage layer, and a method of planting seedlings in a non-tilled state in the field after harvesting grain culms, and There is already known a planting machine that cultivates only a narrow width of the above-mentioned field and plant seedlings in the cultivated portion.

[0003]

Among the known planting methods, the first method requires a great deal of labor to scrape the entire tillage layer and is kneaded to a deep layer to eliminate voids in the soil. Moreover, the planting work had to be done separately. In the second method, the field at the time of planting lacks levelness due to combine crawler marks and dents at the time of harvest, and there are many old plants and weeds. As it is planted shallowly, floating seedlings and poor growth occur.
Furthermore, in the third method, it is difficult to keep the planted seedlings standing upright because the soil in the cultivated portion of the planted row is not sticky.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a field is tilled and then flooded, and in this state, a large number of ridges inclined to the left and right are projected on the circumferential surface at intervals in the axial direction. By supporting the scraping rotor made of so that its axial center is in the lateral direction, and rotating the scraping rotor to move the surface layer of the soil in the plowed field to the left or right by the ridges while advancing it. Streamlining the sub-scraping process so that light sub-scraping and leveling can be performed at the same time, and after plowing the field, water is submerged, and in this state, the sub-scraping rotor is used to remove soil from the plowed field. By scraping the surface layer and then planting seedlings, the surface layer of the tilled and submerged cultivated soil is leveled by spreading the left and right sides alternately by the large number of V-shaped projections on the peripheral surface of the scraping rotor. Then, the above problems were solved by planting seedlings subsequently.

[0005]

[Operation] In the plucking method, after plowing the field, it is flooded,
In this state, a substitute scraping rotor, which has a large number of left and right slanted protrusions projecting laterally at intervals on the circumferential surface, has penetrated the surface layer of the soil being cultivated in the horizontal direction. When the slanted ridges are rotated while rotating, the slanted ridges push the surface soil to the side at the part inclined to one side to mix the soil and water to form a mud, and then the direction of the ridges is the other. When the soil is converted into, the soil on the surface layer is agitated and mixed while extruding it to the other side, and the surface layer of the tillage tillage soil is well kneaded and leveled with less labor due to such lateral spreading and agitation accompanying rotation. In the layer deeper than the scratched surface layer, the plowed state remains, so that many voids can be left, and weeding of the surface layer can prevent weeds from growing.

In the method and apparatus for substituting the scraping, the scraping rotor scrapes the surface layer in a state where the plowed field is submerged, so that the scraping process can be rationalized and the number of parts below the surface layer can be increased. Since it is possible to keep the voids of the seedlings and to plant the seedlings subsequently, it is possible to perform the scratching and the planting at the same time, and the weeds grow after the planting and the floating seedlings are planted at the time of planting. It is possible to prevent shortages and shortages.
