Abstract

The working body of the cultivator, including a stand, a duckfoot share, a blade and a bracket, characterized in that the bracket is mounted on the stand with the possibility of vertical movement along the stand, a holder with an axis is rigidly fixed to the bracket, and loosening discs are mounted on the axis with the possibility of free rotation relative to each other and a dump, moreover, the loosening discs are located between the moldboard and the holder at an acute angle to the direction of movement of the duckfoot paw, and along the periphery of the loosening discs there are teeth, the ends of which are directed towards the row of plants.

Description

The utility model 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 freely mounted axis with the ability to adjust the angular position relative to the direction of movement of the disk, as well as an arm. 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 utility model 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. On the axis with the possibility of free rotation relative to each other, ripping discs and a blade are installed. Riping disks are placed between the blade and the holder at an acute angle to the direction of movement of the lancet paws, and teeth are located along the periphery of the ripping discs, the ends of which are directed towards the row of plants.

Figure 1 shows the working body of the cultivator, a 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 the holder 6 is rigidly fixed with the axis 7. On the axis 7 with the possibility of free rotation relative to each other, ripping disks 8 and a blade 9. A blade 9 is made flat. Riping discs 8 are located between the blade 9 and the holder 6 at an acute angle to the direction of movement of the lancet foot 3. The lower edges of the wings of the lancet paw 3 and the lower point of the blade 9 are on the same horizontal plane and are located on the same level. On the periphery of the ripping discs 8 there are teeth 10, the ends of which are directed towards the row of plants.

The working body of the cultivator operates as follows. Before carrying out inter-row cultivation of row crops, the required depth of movement of the lancet paw is established 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, loosening discs 8, mounted between the blade 9 and the holder 6 on the inside of the wings of the lancet paw 3, with the teeth 10 loosen the soil below the depth of the lancet paw 3, forming a loose and mulched soil layer after the passage of the lancet paw 3, thereby preventing exposure of the bottom furrows.

The implementation of the blade 9 flat and installing it from 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 implementation of loosening discs 8 with teeth 10, the ends of which are directed towards the row of plants, allows loosening 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 by 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. This improves the quality of inter-row cultivation of row crops and improves the temperature, water and air conditions for the development of plants.
