Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a tillage device for tilling and inverting tilled soil with a relatively large amount of soil.

(Prior Art) Conventionally, as means for plowing and inverting cultivated soil with a large piece of soil, for example, the plow tilling method using a plow body and the desk tilling method using a plurality of desks are known.

In the plowing method, the tilled soil is plowed with a tip metal, and the plowed soil is turned over laterally in the direction of propagation using a plow spatula connected to the plow metal.

In addition, in the above-mentioned desk tilling method, the tilled soil is tilled by a plurality of desks that rotate or drive while tilted at a predetermined angle with respect to the direction of travel, and the tilled soil is distributed to the sides of the desks in the direction of inclination. It is designed to be reversed.

(Problems to be solved by the invention) According to the plow tilling method and desk tilling method mentioned above,
The plowed soil is all turned over to the side in the direction of travel, so the entire plowed soil moves to the side by the width of the plowed soil. At the same time, at the edges of fields, after the last plowed soil is turned over, furrows as large as the width of the plowed soil may be formed, and a mid-height phenomenon may occur.
Therefore, there is a problem in that after work by these plowing methods, a lot of labor is required to level and crush the soil that has moved to the sides as a correction work.

Therefore, the present invention has been made in view of the above points, and the tilled soil is plowed in multiple rows, and each plowed soil is turned over into the furrow after plowing. Therefore, it is an object of the present invention to provide a tilling method that prevents the tilled soil from moving to the side.

As shown in FIG. 3, the cultivated soil a is sequentially cut vertically by the rotation of a pair of coulter 13 rotatably mounted on one front end. The bottom part of the cut soil b is successively plowed horizontally to a predetermined depth with the tip part 10 of the plowing guide 9 disposed at the rear of the plowing section. The first row of cultivated soil = c is
The plowing guide 9 is lifted up by the guide 11 and sequentially guided rearward, and is sequentially carried into the carry-in section A of the endless body 22 of the conveyor 16 from its carry-out end. It is transported towards b.

At the same time, each desk 7 is rotated as a unit by the rotation of the rotating shaft 6, and as the rotation of each desk 7 progresses, the tilled soil a is successively tilled in a plurality of rows. At the same time, the tilled soil in each row (d, e, f, g) is sequentially inverted into adjacent grooves (h, i, j, k, l) in the inversion direction. That is, the tilled soil in the second row d is in the groove h of the tilled soil in the first row c, and the tilled soil in the third row is placed in the furrow h of the first row c.
e is in the groove i of the second row of plowed soil d, and f is the plowed soil of the fourth row in the furrow j of the third row of plowed soil e.
Further, the tilled soil (g) in the fifth row is inverted into the groove (k) of the tilled soil (f) in the fourth row.

After reversal of g, it is carried out into groove l, falls down and is reversed.

Therefore, the tilled soil (c) in the first row is replaced by the tilled soil (g) in the fifth row and is reversed, so that Even if each plowed soil d, e, f, g in the 2nd to 5th rows is reversed into the grooves h, i, j, k, l on the side adjacent to the reversal direction, overall, Each plowed soil c, d, e, f, g is the plowed soil c, d, e, f, g.
Furrow h formed after plowing d, e, f, g
i, j, k, l, and the cultivated soil a does not move to the side. As a result, the field after plowing does not have particularly high or middle parts, and the leveling and crushing work becomes easier.

In the above case, the tilled soil a is vertically cut by the pair of coulters 13 in the plowing width of the tilled soil, so this cut soil b is cut into the tip part 10 of the tillage derivative 9
This method allows for orderly plowing, and
Since only the bottom part of the cutting soil b needs to be cut, plowing can be done with small cutting resistance. In addition, each desk 7 is rotatably driven to obtain propulsive force, which reduces cutting resistance and enables efficient and deep plowing.

In addition, in implementation, the length of the conveyor 16 can be shortened by forming the guide member 11 of the tillage guide member 9 in a curved manner so as to extend toward the inner rear side of the desk 7 side. Further, by providing an inversion angle, it is also possible to invert and convey the material to the endless body 22 of the conveyor 16.
