Abstract

FIELD: agriculture.

SUBSTANCE: tool comprises a stand, a centre hoe, a mouldboard and a bracket. The bracket is installed on the stand as capable of vertical displacement along the stand. A holder with an axis is rigidly fixed with the bracket. A tiller and a mouldboard are installed on the axis as capable of free rotation. The tiller is arranged as helical, and its turns reduce in direction from the holder to the mouldboard. The tiller is arranged between the mouldboard and the holder. The least diameter of the tiller's spiral turn is equal to the mouldboard diameter.

EFFECT: structural arrangement of a cultivator tool will make it possible to increase quality of row-to-row treatment of cultivated 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 "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 to improve the quality of inter-row cultivation of row crops.

This goal is achieved by the fact that the bracket is mounted on the rack with the possibility of vertical movement along the rack. A bracket with an axis is rigidly fixed to the bracket. A ripper and a blade are mounted on the axis with the possibility of free rotation. The cultivator is made spiral, the turns of which are reduced in the direction from the holder to the blade, and the cultivator is located between the blade and the holder, and the smallest diameter of the spiral spiral of the cultivator is equal to the diameter of the blade.

Figure 1 shows the working body of the cultivator, top view, figure 2 is a section of the bracket of the working body of the cultivator 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 holder 6 is rigidly fixed with axis 7. A ripper 8 and a blade 9 are mounted on the axis 7 with the possibility of free rotation. The blade 9 is made flat. The cultivator 8 is made spiral, the turns of which are reduced in the direction from the holder 6 to the blade 9. The cultivator 8 is located between the blade 9 and the holder 6, and the smallest diameter of the spiral coil of the cultivator 8 is equal to the diameter of the blade 9.

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 and, accordingly, the thickness of the shifted layer of soil by the blade 9 are set.

When moving a cultivator with deepened working bodies, lancet paw 3 loosens the soil and cuts weeds. In this case, the soil descending from the wings of the lancet paw 3, enters the working surface of the blade 9, the maximum lower point of which is in the same horizontal plane with the lower edges of the wings of the lancet paw and is located at the same level, and moves towards the row of plants, filling weeds in protective zone and hilling cultivated plants. At the same time, the cultivator 8, made spiral, the turns of which decrease in the direction from the holder 6 to the blade 9, and installed between the blade 9 and the holder 6 on the inside of the wings of the lancet paw 3, loosely loops the soil below the depth of the lancet paw 3, forming after the passage of the lancet paws 3 loose and mulched soil layer, thereby preventing exposure of the bottom of the furrow.

The implementation of the blade 9 flat and installing it from the inside of the lancet paws allows you to shift the soil into the protective zone of the row of cultivated crops without its turnover.

The implementation of the cultivator 8 spiral, the turns of which are reduced in the direction from the holder 6 to the blade 9, allows you to intensively 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 moving it 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 cultivator 8, but also the thickness of the shifted layer of soil by the blade 9 into the protective zone of the row of plants.

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