Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural machinery industry, in particular to tillage working elements. The cultivator working element comprises a rack (1), A-hoe (3), a mouldboard (9) and a bracket (4). The bracket (4) is mounted on the rack (1). The bracket (4) is rigidly fixed to the holder (6) and the axis (7). On the axis (7) the chisel discs (8) and the mouldboard (9) are mounted with the ability to rotate freely. The chisel discs (8) and the mouldboard (9) are located on the axis (7) at equal intervals, and are made with an increasing diameter in the direction from the mouldboard (9) to the holder (6). Between the chisel discs (8) and the mouldboard (9) the flexible elements (10) of equal hardness and size are located.

EFFECT: embodiment of the cultivator working element enables to improve the quality of inter-row cultivation of tilled crops.

Description

The invention relates to the field of agricultural engineering, in particular to tillage working bodies.

Known working body of the cultivator [patent RU 100695. The working body of the cultivator. Publ. 12/27/2010, bull. No. 36], comprising a stand and a lancet paw fixed on it, a blade made in the form of a loosely mounted on the axis with the ability to adjust the angular position relative to the direction of movement of the disk, as well as a bracket. The disk is mounted on an additional rack consisting of two parts interconnected by round plates with slots. The plates are mounted perpendicular to the additional stand symmetrically with respect to its center. Radial slots are made on the disk at equal distance from each other.

However, the use of such a working body of the cultivator causes exposure of the bottom of the furrow after the passage of the lancet paw, as well as the unsatisfactory quality of inter-row cultivation of row crops.

The purpose of the invention is improving the quality of inter-row cultivation of row crops.

This goal is achieved by the fact that the bracket is mounted on a rack. A bracket with an axis is rigidly fixed to the bracket. Loosening disks and a blade are mounted on the axis with the possibility of free rotation. The blade is flat and mounted on the inside of the lancet paw at an acute angle to the direction of movement of the lancet paw. The ripping discs and the blade are positioned on the axis at regular intervals and are performed with increasing diameter in the direction from the blade to the holder, and elastic elements of the same stiffness and size are placed between the ripping disks and the blade.

Figure 1 shows the working body of the cultivator, a top view, figure 2 is a section of the bracket along the line aa.

The working body of the cultivator contains a rack 1, a knife-shaped rack 2, a lancet paw 3. A bracket 4 is mounted on the rack 1 with the possibility of its vertical movement along the rack 1. The required position for the height of the bracket 4 is fixed with a bolt 5, screwed into the threaded hole of the bracket 4. With the bracket 4 the holder 6 is rigidly fixed with the axis 7. On the axis 7, ripper disks 8 and blade 9 are mounted with free rotation. The ripper disks 8 and blade 9 are located on axis 7 at regular intervals and are made with increasing diameter m in the direction from the blade 9 to the holder 6. Between the ripping discs 8 and the blade 9 are elastic elements 10 of the same stiffness and size. The blade 9 is made flat and installed at an acute angle to the direction of movement of the lancet paw 3.

The working body of the cultivator operates as follows.

Before inter-row cultivation of row crops, the required depth of the lancet paw is set 3. By moving the bracket 4 along the rack 1, the required depth of loosening of the soil with the loosening discs 8 and, correspondingly, the thickness of the shifted layer of soil by the blade 9. Set the nut (located on the axis 7). compressing or expanding the elastic elements 10, thereby achieving the required distance between the ripping discs 8 and the blade 9.

When moving a cultivator with deepened working bodies, lancet paw 3 loosens the soil and cuts weeds. At the same time, the soil descending from the wings of the lancet paw 3 enters the working surface of the blade 9 and moves towards the row of plants, filling weeds in the protective zone and hilling cultivated plants. At the same time, ripping discs 8, mounted between the blade 9 and the holder 6, loosen the soil below the depth of the lancet paw 3, mulching the soil layer behind the lancet paw 3, thereby preventing the bottom of the furrow from being exposed.

The implementation of the blade 9 flat and installing it from the inside of the lancet paws at an acute angle to the direction of movement of the lancet paw - allows you to shift the soil into the protective zone of the row of cultivated crops without its turnover.

The implementation of loosening disks 8 with an increasing diameter in the direction from the blade 9 to the holder 6 allows you to loosen the soil behind the lancet paw 3, thereby preventing exposure of the bottom of the furrow.

The installation of the bracket 4 with the possibility of its movement together with the holder 6 and the axis 7 in height allows you to adjust not only the depth of loosening of the soil with the loosening discs 8, but also the thickness of the shifted soil layer by the blade 9 into the protective zone of the row of plants.

The installation of elastic elements 10 of the same stiffness and size allows you to adjust the required distance between the ripping discs 8 and the blade 9 when processing different types of soil and its condition.

This improves the quality of inter-row cultivation of row crops and improves the temperature, water and air conditions for the development of plants.
