The invention relates to agriculture and can be used in the construction of deep drainage on water-saturated soils, mainly on irrigated lands.

Known design granolithic, including basic machine, active working body, the guide drainage pipe, a hopper for feeding the filter package and a system of conveyors for poda what about track laying drains formed strip of ground, extracted from the bottom of the trench and having low fertility. To improve the fertility requires the application of high standards of organic fertilizers for a number of years.

Known design granolithic adopted as a prototype that includes the basic machine, active working body, the guide chute drain pipes, hopper, comprising a box formed by two longitudinal and transverse walls (Vasiliev B. A. and others, Reclamation and construction machinery. Moscow, Agropromizdat, 1985, S. 145 - 146, Fig. 101).

When working this granolithic material is transported without removal of the surface between the walls of the trenches and bunkers. This reduces the width of the barren strip above the trench. However, on different soils, depending on soil texture and water content, transported soil differently affects the work of granolithic. In some circumstances it squeezes the bunker on the surface, the other is squeezing the liquefied soil. In this case violated the uniformity of laying drains.

The present invention eliminates these disadvantages. The essence of the proposal is that in the known construction ushtrasana of granolithic, including basic machine, activlearning vertical walls, the hopper has a front cutting edge, while the transverse vertical wall of the enclosure is made of sliding, and a longitudinal vertical wall connected with the front of the cutting part with the possibility of bending in the vertical plane with the help of a few eccentric-spring pairs, installed between the vertical longitudinal walls of the box.

The positive effect of the invention consists in that the transverse wall sliding and supply of the longitudinal walls of the Cam-spring pairs allows you to bend the longitudinal walls, creating the most favorable conditions for the transport of soil between the walls of the trench and bunker, which ensures stable operation of granolithic and because of this improves the quality of laying drainage pipes.

The essence of the proposal is illustrated by drawings, where Fig. 1 gives a General view of granolithic, Fig.2 - section of the hopper along a-a in Fig.3 - section of the hopper along B-B of Fig.4 - section B-B, Fig. 5 - set the eccentrics with the formation of the trough walls.

Granolithic includes the basic machine with 1 active working body 2, the guide tray drain pipes 3 and bin 4, which consists of the front of the cutting part 5 of the hopper 4 and box 6, bratiami and connected to the longitudinal walls 11 and 12. The rear transverse wall 8 consists of sliding sections 13 and 14, also installed with overlapping and connected to the longitudinal walls 11 and 12, which are connected to the front of the cutting part 5 of the hopper 4 rods 15. Between the longitudinal walls vraspor mounted on axes 16, 17 and 18 of the eccentrics 19, 20 and 21, and on the axes 22, 23 and 24 eccentrics 25, 26 and 27. In the plane of the eccentrics 19, 20 and 21 of the springs 28, 29 and 30, the tightening of the longitudinal walls 11 and 12 in the front and in the plane of the eccentrics 25, 26 and 27 of the springs 31, 32 and 33, tightening the longitudinal walls 11 and 12 at the rear of the box. All eccentrics provided with protrusions 34 under the wrench, in the wall 12 against the protrusions 34 are made slits with flaps 36, mounted flush with the wall.

The work of granolithic is performed in the following sequence: before installing it on the track, on the basis of the degree of water content of the soil, regulate the position of the walls 11 and 12 boxes of the hopper 6. When severe flooding heavy soils, removing the dampers 36, the key is in the slot 35 for the tabs 34 rotate the eccentrics 19 and 21 on the axes 16 and 18 and eccentrics 25 and 27 on the axes 22 and 24, setting their greater axis perpendicular to the walls 11 and 12. Thus the springs 28, 30, 31 and 33 are stretched, CTE is ogene eccentrics (any known way) valve 36 is installed in the slot 35 is flush with the plane of the walls 11 and 12 and granolithic out on the track. In the process of laying drainage pipes liquefied plastic material is transported by educated deflection in the walls 11 and 12, providing stable operation of granolithic.

The expansion of the lower part of the hopper prevents the flow of liquefied soil to drainage pipe and prevents the risk of colmatage. This increases the size of the package. Expansion boxes upper part prevents the removal of the pulp on the surface of the field.

When working in dry soils adjustment of the position of the walls 11 and 12 produce turns eccentrics 26 and 27 on the axis 23 and 24. When this box 6 takes the form of a wedge, widening in the lower part (the Cam 26 rotates in an intermediate position between the position of the eccentrics 25 and 27).

Giving the box of this form will prevent the ejection of the hopper from the trench will reduce the load on it by partial displacement of the soil in the upper part of the trench.

Thus, changing the position of the eccentrics can make the walls of the box 6 of the form most favorable to work in specific conditions drained array that provides the reliability of granolithic and uniformity of laying drainage.

Formula of the picture is Noah pipe, hopper, comprising a box formed by two transverse and two longitudinal vertical walls, wherein the hopper has a front cutting edge, while the transverse vertical wall of the enclosure is made of sliding, and a longitudinal vertical wall connected with the front of the cutting part with the possibility of bending in the vertical plane with the help of a few eccentric-spring pairs, installed between the vertical longitudinal walls of the box.
