Description

WITH

The described alleged invention relates to the field of agricultural engineering, in particular to the design of tillage machines and can be used for pre-sowing tillage.

The purpose of the invention is high-quality presowing cultivation of the soil, allowing the soil to be prepared in accordance with the requirements set forth by plants in the sub-seed, seed and sub-seed layers.

In FIG. 1 shows a proposed tillage implement, side view; in Fig.2 - an element of a spiral roller with L-shaped tillage elements; in FIG. 3 - overlapping of the compacted zone with L-shaped tillage

elements of two sequentially located rollers guns.

The proposed tillage implement consists of a frame 1 with a vibrator 2 mounted on it, driven by a hydraulic motor and two spiral rollers 3, axles 8 of the axis of the spiral rollers, fixed in the cages of roller bearings mounted on the frame 1 of the implement. On one side of the guns on both pins 8 there are sprockets interconnected by a chain gear

4 with the help of which the coordinated rotation of the rollers is carried out 3. On the cylindrical surface of the rollers 3, made in the form of a spiral, L-shaped soil cultivating elements are mounted with the possibility of movement in a vertical plane

5 - blades with a wing for soil compaction.

Aggregation of the implement on the frame of another implement or the hitch of tractor b is carried out by means of spring suspensions 7.

The tillage tool described above works as follows. Having moved the tillage implement from the transport position to the working position, the hydraulic motor drive is switched on and the tractor moves forward (the implement can be mounted directly on the tractor or can be mounted additionally behind the tillage implements). During operation, the vibrator 2, driven by the hydraulic motor, creates the necessary vibration for good soil cultivation . In this case, due to vibrational and rolling forces, the L-shaped tillage elements 5 are introduced into the soil, which crush and crumble the sub-seeded soil layer. At the moment of passage of the L-shaped tillage elements in the plane of the compacted seed bed, the greatest effect from the action of vibrational forces will be observed, as a result of which the seed bed is compacted. The overlap of the compacted zone of the L-shaped tillage elements 5 is coordinated by a chain transmission 4 between the spiral rollers 3.

In the process of movement, the top soil layers will not only crumble, but will also be compacted due to the spiral base of the roller 3. The mobility of the structure, the damping of the vibration transmitted to the previous implement or tractor, and also the pressing of the implement to the soil are provided by spring suspensions 7.

The expected economic effect of using the proposed tillage implement can be achieved.

due to the high-quality formation of the northern and subsecond soil layers.

The proposed technical solution makes it possible to improve the quality of pre-sowing tillage, as a result of which the percentage of germination of plant seeds and their productivity are increased.
