Abstract

The invention relates to agricultural machinery, in particular, to the mechanization of irrigated vegetable production. The aim of the invention is to prevent damage to plants by the wheels of the tractor by shifting the bottom of the furrow. The cultivator contains a longitudinal frame 2, mounted on the tractor 1. On the frame 2, the transverse beam 3 is hinged with working tools. Each working body is made in the form of a vertical stand 5 with a paw 6. The lower part of the stand 5 is bent from a longitudinally vertical plane at an angle of 35-45 °, and its top is facing the axis of symmetry of the cultivator. Before the cultivator starts working, the working bodies are buried. The presence of a bend at stand 5 of 35-45 °, equal to the angle of the slope of the roller of the furrow, provides for loosening the slope and moving the soil to another slope of the furrow. Due to this, the bottom of the furrow is displaced by a distance equal to half the width of the paw 6 grip. 3 Il.

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to the mechanization of irrigated horticulture.

The aim of the invention is to prevent damage to plants by the wheels of the tractor by shifting the bottom of the furrow.

FIG. 1 shows the location of the working bodies and the profile of the furrows formed by them, the cross section; in fig. 2 - cultivator, side view; in fig. 3 - the same, top view.

The cultivator contains a tractor 1, a longitudinal frame located in front of it 2 s and a transverse bar m 3 fixed to it, a hydraulic cylinder 4 and working elements fixed to the bar 3, having racks 5 and feet 6. Each rack 5 is vertical and in the lower part bent from the longitudinal-vertical plane at an angle of 35-45 °, the top of which is facing the axis of symmetry of the cultivator. The frame 2 is fixed on the tractor 1 through the holes 7.

The cultivator works as follows.

Before the cultivator starts working between the spaces with the help of the hydraulic cylinder 4, the working bodies are brought to the working position. At this time, the working bodies, mounted in front of the front wheels of the tractor 1, are lowered onto the free inclined surface of the furrow roller. The presence of the bend of the stand 5 at an angle of 35-45 ° is equal to the angle of repose of the furrow,

allows the working body to copy the surface to be ground and, when the aggregate moves, to evenly penetrate to the set depth throughout the entire width of the grip. In the process, a significant part of the soil

The processed horizon is thrown onto another inclined surface of the roller of the furrow and its bottom is mixed by a distance (L) equal to half the width of the paw 6 of one working member.

Claims (1)

5 Formula of Invention A cultivator for processing between vegetables between crops, containing a frame with a transverse bar articulated with it, mounted on the latter by working bodies in the form of vertical stands with pointed legs, and a mechanism for raising working bodies, in order to prevent damage to the plants the tractor wheels by mixing the bottom of the 5th furrow, the stand of each working body in the lower part is bent from the longitudinal-vertical plane at the angle of 35-45 °, the top of which is facing the axis of symmetry of the cultivator. 0 k
