Description

 The invention relates to agricultural machinery and is intended for soil treatment.

There is a cultivator equipped with disks located in the transverse vertical plane on inclined axes and made cut into teeth. When the teeth are immersed in the soil, the disks shift it to the side and lift it up, which ensures loosening [1]
The disadvantage of this cultivator is that with this cultivator it is not possible to carry out loosening using the non-moldboard method and there remains a crest of loose soil between the discs.

 The aim of the present invention is the implementation of subsurface loosening throughout the depth of immersion of the discs.

 The goal is achieved by the fact that cuts are made on the disks in the direction of the diameter or deviating from this direction, and one or both of the edges of this cut is bent outward or inward of the disk shape with the installation of these disks on inclined axes located in transverse vertical planes.

 This goal is achieved, since when the ripper is immersed in the soil and its forward motion, the disks immersed in the soil, due to the resistance to movement of the bent edge of the disk carry out rotational movement, and the application of the resistance force is located above the lowest point of the disk. As a result, the lower point of the ripper acquires a movement directed in the direction opposite to the movement of the ripper relative to the soil. Depending on the need for the direction of loosening, the disk may be located forward of the section bent inward or outward. A similar situation occurs in the drive disk. Since the lower part of the disk cannot create a resistance force sufficient to drive the cultivator into motion, the resultant force arises above the lower point of the disk immersed in the ground. As a result, the cultivator acquires movement in one direction relative to the ground, and the lower part of the disk in the other. Since the lower part of the cultivator is bent away from the direction of movement, then when moving backward, it moves the lower layer of soil, loosening it. In addition, the performed bends of the cuts carry out pruning of the roots of the weed, which deviated when the soil was shifted, but remained intact.

 Figure 1 shows a General view of the cultivator; figure 2 shows a view along arrow a in figure 1.

 The cultivator contains a housing 1 (see figure 1) for the use of a cultivator on the beds, or a frame (not shown) for loosening large areas. The housing 1 has holes for mounting on the axles 2 of the disks 3, for installing the handle 4 for moving the cultivator along the bed and holes 5 for securing the load (not shown). Bearings 6a can be installed between the housing and the disk, and on the other side of the plate 7 are also located on the bearings 8. On the disk 3, cuts are made with the formation of edges 9, bent outward and edges 10, bent inward to the shape of the disk, or left unchanged. Edges 9 and 10 may be sharpened depending on the purpose of the ripper. On the outer part of the disk 3 there is a cutting edge 11, cutting into parts and divorced by limb or limb. Disks can have two planes facing one up and one down and connected by one surface, which is cut in such a way, and one facing down, and a cone (not shown) can be mounted on the top to mount the disk instead of axis 2. To increase productivity the edge 11 can be made gear (not shown). The cut on the disk 3 can be made both in diameter and with a deviation from this direction.

 The ripper works as follows.

 Under the weight of the case or frame (not shown) and the load (not shown) installed on it and secured by bolts screwed into the holes 5 (Fig. 1), the disks 3 with their cutting edges 11 (Fig. 1,2) are immersed in the ground and when the cultivator moves by acting on the handle 4 or the frame drive (not shown), if they are mounted on the axis 2 with free rotation, they rotate on bearings 6 and bearings 8 fixed by the plate 7, while the bent edges 9 or 10 abut against the ground and create the greatest movement resistance. The center of application of the resistance force is located above the lower immersion point of the cultivator. Therefore, the lower point of the cultivator, immersed in the soil, acquires a movement opposite to the movement of the cultivator relative to the soil. But since the edges 9 and 10 are divorced, the movement of the edge 11 of the disk will be accompanied by a shift of the soil to the side transverse to this movement. And if the movement of the cultivator creates resistance edge 10, bent inward to the angle of inclination of the disk, then the shift of the soil is also directed inside this angle. If the movement of the cultivator the main resistance creates the edge 9 bent outward, then the soil is shifted from the disk 3 to the outside of the angle of inclination of the latter. If the drive 3 is drive, then the drive force will also be applied to the point of greatest soil resistance at the bent edge 9 or 10. The movement of the cutting edge 11 of the disk 3 is directed in the opposite direction to the movement of the cultivator relative to the soil. The soil shift in this case will be similar to the shift of the disks freely rotating on the axes 2. If the disks 3 follow one after the other with the rear shafts moving relative to the front along the movement of the cultivator, then this soil shift allows loosened soil to be obtained over the entire depth of immersion of the 3 cultivator disks. In addition, the bent edges 9 and 10 in their movement carry out an additional cut of the roots of the weed to the undercut by the edges 11.

Claims (1)

 A soil cultivator containing disks located on inclined axes located transverse to the movement, characterized in that the disks are made cut in a direction from a larger diameter to a smaller one with a dilution of one or both edges of the disk cut site.
