Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agricultural machinery industry, in particular to tillage working elements. The working element of the cultivator comprises a rack, an A-hoe, a mouldboard and a bracket. The bracket is mounted on the rack. An adjustment disk with an axis is rigidly fixed on the bracket. Under the adjustment disk an additional disk is mounted with the ability to rotate around its axis, and under the additional disk a guide bracket with a semiaxis and a mouldboard is rigidly fixed. The mouldboard is made flat and is mounted on the semiaxis on the inner side of the A-hoe, and the lower edges of the A-hoe wings and lower point of the mouldboard are in the same horizontal plane and are located at the same level.

EFFECT: design implementation of the working element of the cultivator 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 "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 known device has the disadvantage associated with 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. An adjustment disk with an axis is rigidly fixed to the bracket. An additional disk is mounted under the adjusting disk with the possibility of rotation around its axis, and a guide bracket with a half shaft and a blade are rigidly fixed under the additional disk. The blade is flat and mounted on the half shaft from the inside of the lancet paw, and the lower edges of the wings of the lancet paw and the lower point of the blade are in the same horizontal plane and are on the same level.

Figure 1 shows the working body of the cultivator, side view, figure 2 is the same top view, figure 3 is a cross section 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. An adjustment disk 5 with an axis 6 is fixed on the bracket 4. An additional disk 7 is mounted under the adjustment disk 5 with a possibility of rotation around its axis 7. Adjusting the disk 5 and the additional disk 7 have holes 8 located on the periphery at the same distance from their center. Under the additional disk 7, a guide bracket 9 is rigidly fixed with a half shaft 10 and a blade 11. The shaft 10 is rigidly mounted on a guide bracket 9. A cylindrical housing 12 with a bearing 13 is fixed on the blade 11. The blade 11 is made flat and is mounted on the half shaft 10 with an internal shaft 13 side lancet paws with the possibility of rotation around its axis and change the installation angle to the direction of movement. The lower edges of the wings of the lancet paw and the lower point of the blade are in the same horizontal plane and are located at the same level. The required blade angle 11 is set by rotation of the additional disk 7 together with the guide bracket 9 and the axle shaft 10 around the axis 6 of the adjusting disk 5 and fixed in the desired position by a bolt 14 inserted into one of the holes 8.

The working body of the cultivator operates as follows. Before conducting inter-row cultivation of row crops, the required angle of the blade 11 is set to the direction of movement of the cultivator, the required processing depth depending on the height of the plants.

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 11 and moves toward the row of plants, filling weeds in the protective zone and hilling cultivated plants.

The implementation of the blade 11 flat and installing it on the inside of the lancet paw - allows you to shift the soil into the protective zone of the row of cultivated crops without its turnover.

The holes 8 on the periphery of the adjusting 5 and an additional 7 discs located at the same distance, allows you to adjust the angle of the blade 11 relative to the direction of movement of the lancet paws 3, as well as to set the blade 11 on the right or left side of the rack 1, to adjust the range of the soil, providing falling asleep weeds in the protective zone of cultivated plants with a layer of soil of a given thickness. This improves the quality of inter-row cultivation of row crops and improves the temperature, water and air conditions for the development of plants.
