Abstract

The invention relates to agricultural machinery, in particular to tillage tools. The aim of the invention is to improve the quality of tillage and reduce energy intensity. The section consists of a hinge 1 and hil 2, on which crossbars 4 with working bodies 5 are fixed. The working bodies 5 with loosening paws 8 are located symmetrically relative to the longitudinal axis of the hil 2 in the form of a wedge. In front of the working bodies 5 on the gr dile 2, there is a strelchat paw 9. The front surface of each of the loosening paws 8 faces the longitudinal plane of symmetry of the section and makes an angle of no more than 76 ° with it. This ensures loosening of the soil in the immediate vicinity of a number of plants without damaging the loosened soil and reducing drag. 1 hp f-ly, 4 ill.

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to tillage tools.

The aim of the invention is to improve the quality of soil treatment and reduce energy intensity.

FIG. 1 shows a section cultivator, side view; in fig. 2 - the same, top view; in fig. 3 - working body, side view; in fig. 4 is a section A-A in FIG. 3

The section of a tilled cultivator consists of a four-link parallelogram-hitch mechanism 1 and cus 2, on which the support wheel 3 and crossmembers 4 are fixed with working bodies 5. Each of the working bodies 5 consists of a stand 6 connected to the coulter 7 and loosening paw 8. The working bodies 5 are located on both sides of the pile saw 2 symmetrically to its longitudinal axis in the form of a wedge. In front of the working bodies 5 on the gr dile 2, there is a strelchat paw 9. The front surface of each of the loosening paws 8 is placed at an acute angle to the axis of symmetry of the section and makes up an angle of no more than 76 ° with it.

Section cultivator works as follows

Before starting work, depending on the width between the spaces, the position of the working bodies 5 is adjusted in the horizontal plane using transition brackets (not shown). Grdil 2 is located in the middle of the aisle, and the working bodies 5 - symmetrically relative to its longitudinal axis, the stroke depth of which increases in steps to the middle of the aisle. The extreme loose legs 8 are located in close proximity to a number of plants.

In the course of tillage, the stalked paw 9 moves in the middle between the rows, while its stand cuts a gap in the soil, making it easier for the soil following the lancet paw 9 to loosen the paws 8. Clearing the front surface of the loosening paws 8 at an acute angle to the longitudinal the vertical plane of symmetry of not more than 76 ° ensures good loosening of the soil near the soil without damaging them with a minimum width of 4-5 cm of untreated soil strip, and also dragging is reduced.

Claims (2)

1. Section of a tilled cultivator, including a four-link parallelogram linkage mechanism and a groove on which the supporting wheels and crossmembers with working bodies, each of which is designed as a stand with a paw, are attached, while the working bodies are located symmetrically relative to the longitudinal axis the formation of a wedge, and along the axis of symmetry of the wedge, a strelchat paw is installed, characterized in that, in order to increase the quality of tillage and reduce energy intensity, the paw of each working body is made loose, and its Bov surface is placed at an acute angle to the axis of symmetry of the section, the apex of which is turned in the direction opposite to the direction of movement. 2. The section according to claim 1, characterized in that the angle between the frontal surface of the loosening 35 paws and the axis of symmetry of the section is no more than 76 °.
