Abstract

Usage: surface tillage in agriculture. The essence of the invention: at the moment of impact of the working elements, the soil lumps of the arc elements 6, having penetrated into the soil, loosen it, and elastic elements, for example coil springs 7, are compressed in the direction N. Further, due to the force of pressing the spring 7, clearing the space P from soil repelled from the surface of the arable land. During compression of the spring 7, the soil lumps located between adjacent arc elements 6 are pinched between their coils and further destroy them into smaller fractions. After the working element leaves the zone of interaction with the soil, coil springs 7 occupy the initial position. In this case, due to the pressing, the pitch of the spring turns increases, and the soil lumps located between them are released and discarded under the action of centrifugal force. 2 cpf, 8 silt, View (Л С -Nj | Vj О-ч cl

Description

Fig.Z

The invention relates to agricultural machinery and can be used in implements for surface soil cultivation.

The purpose of the invention is to improve the quality of tillage.

In Fig.1 schematically shows a tillage working body, side view; in Fig.2 - a working element of a soil cultivating rotary working body; in Fig.Z - VI L in Fig.Z, with an elastic element made in the form of a helical spring; figure 4 is the same, but with an elastic element made in the form of a zigzag spring; figure 5 - zigzag spring, front view; figure 6 is the same side view; figure 7 is the same. but n is bent; Fig.8 is a section bB in Fig.2.

The tillage rotary working body comprises a hollow drive drum 1 located perpendicular to the direction of movement of the implement with a horizontal axis of rotation, on the forming surface of which there are holes 2 with guide bushes 3 mounted therein.

Each pair of holes 2 are located on diametrically opposite points of the surface of the drum 1. Through the sleeves 3 in this pair of holes, a flexible holder 4 is pulled through the drum, at both ends of which are fixed working elements 5 made in the form of a spherical frame of alternately rigid 6 located on the semicircles and elastic 7 ripper elements connected by the ends 9 (10) and 11 (12) to each other at opposite poles of the Y sphere.

Elastic ripping elements can be made in the form of screw 7 or zigzag 8 springs.

The flexible holder 4 is a cable, chain or other similar element.

In the process, the rotary working body performs both translational (with speed Vn) and rotational (with speed co) motion. The working elements 5 due to centrifugal force are removed from the axis of the drum 1 over the entire length of the extension of the flexible holders 4 and hit lumps of soil with high kinetic energy. In this case, the rigid loosening elements b of the working element 5, breaking up the soil lump, are partially embedded in it, thereby increasing the effect of loosening the soil. At the moment of introducing the rigid loosening elements 6 into the soil, the elastic loosening elements 7 are initially compressed in the N direction, and subsequently, due to the burning force, they clear the space P between

adjacent rigid loosening elements 6 from the soil, repel from the surface of the arable land. During compression, the elastic ripping elements 7. are pinched between

with their coils, soil lumps located between adjacent rigid cultivating elements b further destroy them into smaller fractions. After the exit of work item 5 from

In the zone of interaction with the soil, the elastic loosening elements 7 return to their original position. At the same time, the spring pitch of the elastic loosening elements increases, and the soil lumps located between them are released by centrifugal forces and are discarded.

Thus, in the proposed technical solution due to compression and squeezing in

In the process of working of elastic loosening elements, the working elements, additionally destroying soil lumps, self-clean from sticky soils and thereby generally improve the quality of soil treatment.
