Description

I

The invention relates to agricultural machinery, in particular to devices for pre-sowing tillage. ,

A soil equalizer is known, consisting of a blade installed at an angle to the direction of movement and having soil scavengers installed in the windows of the blade p.

A disadvantage of the known device is the impossibility of creating an even surface of the floor, since the soil coming from the blade forms a swath that needs to be leveled.

A soil equalizer is also known that includes planning working bodies and soil throwers installed under yi to each other.

A disadvantage of the known device is the unevenness of the cover with the mulched soil layer of the entire treated surface, which degrades the quality of the soil treatment before sowing.

The purpose of the invention is to improve the quality of tillage.

The goal is achieved by aligning; the soil nivateur is equipped with an undercutter installed between the planning working bodies, with the throwers located above the upper edge of the undercutting knife, and their axis

10 rotation is inclined at an acute angle to the horizon as the unit moves.

Throwers are equipped with a device for adjusting their tilt angle.

FIG. 1 shows a soil equalizer, side view; in fig. 2 the same, top view.

The soil leveler consists of a frame 1, on which the plan. working working bodies 2, having plowshares 3 and dumps, and between them are mounted undercutting knives 5, above

the upper edge of which is equipped with throwers 6 having an inclined axis of rotation 7 at an acute angle to the horizon along the course of the unit. Behind the throwers 6, the fence 8 and the press rollers 9 are installed. The tilt adjustment mechanism of the axis 7 of the throwers 6 is made in the form of a hydraulic cylinder 10, and the thrower is fixed on the frame 1 by means of a hinge 11 and mounted on the plate 13 together with the gearbox.

Soil equalizer works as follows.

When the plowshare 3 moves, it cuts the soil layer at a set depth, and the dumps k move the soil cut by the knives 3 to the runway of the undercutting knives 5. The soil, overhanging the upper edge of the knife 5, falls on the throwers 6 and spreads like a fan along the aligned strip. The spread width of the loose soil is controlled by changing the angle of inclination of the axis 7 of the throwers 6 produced by the hydraulic cylinder 10. Rolling the loose soil layer is carried out by rollers 9. A more uniform shelter of the treated areas with a mulch soil improves the quality of the seedbed.

soil preparation and crop yields.

Claims (2)

1. Equalize the soil, including planing tools and soil throwers installed on the frame at an angle to each other, which is equipped with a pruning knife installed between planners, while throwers are located above the upper edge of the trimming knife, and their axis of rotation is inclined at an acute angle to the horizon. along the movement of the unit. 2. The leveler according to claim 1, is about the fact that the throwers are equipped with a device for adjusting their angle of inclination.
