Abstract

The utility model relates to agriculture. The rotary working body for soil cultivation consists of a rack with a rotary cultivator mounted on bearings of a bearing assembly with the possibility of rotation around its own axis. The rotary ripper has a pointed nose, a drill-shaped groove turning into a cone, as well as ripping elements located along a helical line and rigidly fixed on the surface of the working body. The rotation of the rotary ripper is carried out by means of a chain transmission, which is covered with a casing with the bearing assembly of the ripper. Loosening elements are placed on the surface of the working body along a helical line at an angle of 60°. EFFECT: improved quality and reduced energy consumption of non-moldboard tillage. 4 ill.

Description

The utility model relates to agricultural engineering, in particular to working bodies for tillage subjected to water-wind erosion, including in fields with areas that do not allow atmospheric precipitation to pass moisture.

A device for non-moldboard tillage (author's certificate SU 1701121 A1 30.12.1991) is known, consisting of a rack on which a collapser of arches is placed. The vault breaker is located inside the main breaker. The loosening elements of the vault breakers are made in a spiral, and their cutting edges are placed radially. The winding of the spirals of the collapsers of the arches is made opposite to one another.

The disadvantage of this device is the uneven tillage in depth due to poor stability of the ripper. At the same time, the winding of the chopper spirals increases the clogging of the working body with plant residues and soil. Clogging the space between the loosening elements can lead to a stop in the rotation of the working body.

The closest analogue of the proposed utility model is a device consisting of a knife-like rack with a hollow drainer and a collapser of arches, the loosening elements of which are made in the form of a multi-start conical logarithmic spiral mounted on a shaft (author's certificate SU 1373336 A1 02/15/1988). The shaft is mounted on bearings mounted in a hollow drainer and is equipped with a large gear engaged with a small gear of the shaft of a conical rotary ripper. The screw working ribs of the cone ripper smoothly pass into a pointed toe, which has a cruciform cross-section.

The disadvantage of this invention is the complexity of the design, low reliability of the device for non-moldboard processing, as well as unsatisfactory loosening of the soil due to clogging of the cone rotary cultivator with soil, which sharply reduces the efficiency of this design.

The objective of the utility model is to eliminate these disadvantages of analogs and prototype.

The technical result of the proposed utility model is to improve the quality of non-moldboard tillage due to intensive loosening of the soil with simultaneous energy consumption of non-moldboard tillage due to loosening elements located in a spiral on the surface of the working body with an active drive.

The use of this design will improve the quality of tillage and reduce energy consumption.

The technical result of the claimed utility model is achieved in that the rotary working body for tillage includes a rack, a rotary cultivator mounted on bearings with the ability to rotate around its own axis by means of a chain drive, loosening elements placed on the surface of the working body along a helical line at an angle of 60° . The rotary working body has a pointed nose, a drill-shaped groove, smoothly turning into a cone. The chain drive and bearing assembly of the ripper are covered with a casing. Loosening elements arranged in a spiral and rigidly fixed on the surface of the working body.

The utility model is presented on

fig. 1 - Rotary working body (side view);

fig. 2 - Local section of the bearing assembly and drive;

fig. 3 - Front view (view along arrow A);

fig. 4 - Cross section of the rack (section B-B).

The rotary working body for soil cultivation consists of a rotary cultivator 1 with a groove 2 in the form of a drill, loosening elements 3, placed evenly at an angle of 60° on the surface of the working body along a helical line, rack 4, chain transmission 6, a ripper bearing assembly 7 and a cover for service.

Device for nonmoldboard tillage works as follows.

When the device is lowered and the movement starts, the rotary cultivator 1 is introduced into the soil and deepened to the set working depth. With the simultaneous translational and rotational movement of the rotary cultivator, the effect of drilling occurs, and the ripping elements 3 contribute to loosening the soil and destroying weeds.

Thus, the use of the claimed device for tillage makes it possible to form a layer of soil with favorable conditions for the growth of plants, the preservation and accumulation of moisture, as a result of which an increase in yield is expected.
