Abstract

This invention relates to agriculture. The purpose of the invention is to improve the quality of laid mole drains. The device for laying mole drains consists of a frame 1 with a knife 2 rigidly attached to it, a depth limiter 10 and a hingedly attached frame 4. There are seals 5 installed on the frame, made in the form of plates mounted on racks 6. The device also includes a drier 3 and a drier 9 The posts 6 of the seals 5 are rigidly attached to the bed 4. The seals 5 are installed alternately to the left and right of the draining axis have opposite tilt angles and a sharp angle of entry into the soil. 2 Il.

The invention relates to agriculture and can be used for subsurface irrigation of drainage and utilization of wastewater mainly on soils of heavy mechanical composition.

The purpose of the invention is to improve the quality of laid mole drains.

FIG. 1 shows a side view of the device; nor fip. 2 is a diagram of successive operations for the formation of mole drains.

The device consists of a frame 1 with a vertical knife 2 rigidly fixed on it with a drape 3. The frame 4 is hingedly connected to the frame 4 with seals 5 installed in series with it. The seals 5 are made in the form of plates fixed on racks 6. The plates 5 are mounted obliquely alternately shifted left and right from the axis of the drainer 3. Seed plates 5 have opposite angles of inclination and are provided with a front cutting edge with a sharp angle of entry into the soil. At the end of the bed 4 there is a powder

The device works as follows.

When the machine moves (a tractor with the proposed device), knife 2 cuts a slit 8, along the bottom of which α drains 3 is pulled, and the seals 5 cut alternately left and right into the walls of the slit 8, detach from them to the center

the space, and under the action of the mass of the loaded bed 4 and the tractor pull force (due to the presence of an acute angle of entry of seals 5 into the soil) compact this soil over the draining unit 3 and in its sinuses in several steps (according to the number of seals 5). After the last compactor 5 passes over the draining unit 3, the latter is removed from the soil compacted around it, leaving the cavity of the mole 9 in it. With the last operation, the powder device 1 levels the track of the slit-shaped sealants 5 and the trace of the slot 8 with the surface. The depth of laying of the mole is fixed by the depth limiter 10.

Claims (1)

Invention Formula A device for laying mole drains, comprising a frame with a vertical knife rigidly fixed on it with a draining unit, a frame hinged to the frame with sequentially installed on it a sealant and a powder machine, characterized in that, in order to improve the quality of laid mole drains, the seals are made in the form of a plate inclined alternately offset to the left and right of the axis of the drener, the latter plates having opposite angles of inclination and provided with a leading cutting edge with a sharp angle walking into the soil.
