Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agricultural machinery industry and can be used for inter-row soil cultivation. The working body of the cultivator comprises a rack and a fixed A-hoe with a mouldboard. The mouldboard is made in the form of a spherical disc freely mounted on the axis with the ability to move along the rack and to adjust the angular position relative to the direction of motion. The mouldboard is located with its convex side to the rack with the possibility of installation at its both sides and change of the gap between it and the inner surface of the A-hoe. The working body of the cultivator also comprises a bracket on which the plate is mounted on it with an additional bracket with the disk axis fixed on it. The disk axis is mounted on the additional plate fixed on the additional bracket with the ability to adjust the angular position of the disk in the vertical plane on the value β=0…45°. On the disk there are slits which are symmetrical related to the axis, at equal distance from each other.

EFFECT: invention enables to improve the quality of inter-row soil cultivation and to reduce the force for the movement of the working body.

Description

The invention relates to agriculture and can be used for inter-row tillage.

Known working body of the cultivator [Working body of the cultivator. Patent RU No. 2245007 C2. Publ. January 27, 2005], comprising a rack and a lancet paw fixed to it with a blade made in the form of a loosely mounted on the axis with the ability to move along the rack and adjust the angular position relative to the direction of movement of the disk, as well as an arm on which a plate is mounted with her additional bracket with the axis of the disk.

The disk is made spherical, located convex side to the rack, with the possibility of installation from its both sides and changing the gap between it and the inner surface of the lancet paw. The drive axis is mounted on an optional bracket. The scraper is made in the form of a double-toothed fork and mounted on an additional bracket radially in the upper rear part of the disk. The inner surface of the scraper copies the shape of the outer surface of the disk profile.

However, the known working body of the cultivator has the following disadvantages: low quality inter-row cultivation of row crops, as well as significant energy costs for processing.

The aim of the invention is to improve the quality of inter-row cultivation of row crops, as well as reducing the effort to move the working body.

The goal is achieved by the fact that the axis of the disk is mounted on an additional plate fixed to an additional bracket. On the additional plate, holes are made in the form of a sector located at an equal distance from each other, and a groove is made on the axis of the disk with the possibility of adjusting the angular position of the disk in a vertical plane. Slots are made on the disk, which are symmetrically relative to the axis at an equal distance from each other.

Figure 1 shows a General view of the working body of the cultivator; figure 2 is the same, a top view; figure 3 is the same, rear view; figure 4 is a view of A.

The working body of the cultivator contains a rack 1 and a lancet paw 2 fixed on it with a blade made in the form of a freely mounted axis 14, with the ability to move along the rack 1 and adjust the angular position relative to the direction of movement of the spherical disk 4, as well as the bracket 3. On the bracket 3 a plate 5 is mounted on which an additional bracket 6 is fixed. An additional plate 13 is mounted on an additional bracket 6, on which the axis 14 of the disk 4 is fixed. The disk 4 is located on the convex side of the rack 1 s installation possibilities from both its sides and changing the gap between it and the lancet paw 2. The fixing bolt 7 is provided on the rack 1 to fix the position of the bracket 3. The plate 5 has holes 9 necessary to adjust the angular position of the disk 4 with respect to the direction of movement. The position of the additional bracket 6 relative to the plate 5 is fixed with a bolt 12. The tapping disk 4 is mounted on an axis 14, which is fixed to the additional plate 13 with a bolt 16. The additional plate 13 has holes 11, and there is a groove 15 on the axis 14 of the disk 4 to adjust the angular position of the disk 4 in the vertical plane by β = 0 ... 45 °. On the disk 4, slots 17 are made, which are symmetrically relative to the axis at an equal distance from each other.

The working body of the cultivator operates as follows. Before inter-row cultivation of row crops or vegetables, the necessary adjustments are made to the cultivator's working bodies depending on the speed of movement, the width of the protective zones, the type of cultivated crop and the age of the plants. Changing the position of the disk 4 in height is achieved by moving the bracket 3 along the strut 1 with subsequent fixation with the locking bolt 7. Adjusting the angular position of the disk 4 relative to the direction of movement of the working body of the cultivator is provided by fixing the additional bracket 6 through the holes 9 of the plate 5 with bolts 12. Adjusting the angular position of the disk 4 in the vertical plane (β = 0 ... 45 °) is provided by fixing the axis 14 of the disk 4 through the holes 11 of the additional plate with bolts 18.

When moving the cultivator with recessed working bodies, the lancet paw 2 cuts the soil layer, loosens it and cuts the weeds. In this case, the soil layer descending from the paw 2 enters the working surface of the disk 4 and moves to the side, filling the weeds in the protective zone and ensuring the earthing up of the plants. Partially, the soil is poured through the slots 17 of the disk 4, preventing the soil from sticking to the disk 4, exposing the bottom of the furrow and increased evaporation of moisture from the soil.

The working body of the cultivator provides regulation of the distance of the soil casting, ensuring that the weeds fall asleep in the protective zone of cultivated plants with a layer of soil of a given thickness.

Possibilities of installing the disc on any of the sides of the lancet paw, changing its angular position in the vertical plane and the angular position relative to the direction of movement allow you to choose the optimal inter-row processing mode, as well as reduce the effort to move the working body when performing this process.

The implementation of slots on the disk prevents soil from sticking to the surface of the disk when it is wet, since when the working body moves in the optimal mode, the soil, constantly pushed by its new portions, is partially discarded by the disk into the protective zone of cultivated plants, and partially is poured through the disk cuts, filling the bottom furrows, which improves the quality of inter-row cultivation of row crops.
