Device for laying mole drains

 

(57) Abstract:

Use: irrigation, in particular in devices for the formation of soil is resistant to scour the water mole drains, provide subsurface irrigation or disposal of wastewater. The inventive device includes a knife that cuts into the soil with crack extension at the top. Attached to the knife drainer is pulled along the bottom of the cracks extended thickening of the knife to the value of the cross section of tenera. Seals in the form of plates that are installed sequentially on the frame, the downward pressure gradually compacts the soil around tenera. Last after removing it from the already compacted soil around it, leaves in her cavity Krotova drains. Alternately tilt seals left and right, consistent narrowing towards the rear of the device and the location of the bottom faces of the left and right seals in total for each side planes, provide morphogenetic process, and spicy wedges, vertically mounted in the front parts of the outer edges of the seals, further loosening of the soil, prevents sagging of the seals on the solid walls of the expanded part of the slit. 2 Il.

A device (crotwell) for laying mole drains (ed. St. N 1206378, CL E 02 In 11/02, 1986), containing a rack installed on it with a knife and grenera, pivotally connected with a rack frame with cargo and sequentially mounted on the frame rollers for compacting soil over grenera.

However, rollers compaction produce substandard stick, zakladivaetsa in a rut or raked before the soil.

A device for laying mole drains [1] , but it has drawbacks, destabilizing the operation of the seals and hinder the adoption of tenera in soil:

the uncertainty of the relative sizes of seals. The only consistent narrowing of the seals to the rear side of the device can provide stable soil compaction over grenera by concentrating pressure down;

uncertainty installation of seals in height relative to each other. Only install the lower faces of the left and right plates in total for each side planes provides (together with the previous topic) concentration and increased pressure down and nerazresene previously compacted come running with a knife. Then the compaction of loose soil over grenera becomes impossible and requires additional loosening of the trench to form a layer of loose soil between the bottom faces of the plates and grenera.

Drainer can zaglubitelja in the soil and take a horizontal position only in the case of on his way loose soil or voids (openings). To ensure this condition may thickening at the end of the knife, equal in cross section to dinero.

The aim of the invention is to improve the quality Krotova drains.

For this purpose a device comprising a frame rigidly secured to it a vertical knife with a thickening at the end and grenera, pivotally connected to the bed frame with successively installed on it right and left seals, made in the form of inclined plates, and preseptal, and the seals are made consistently with tapering tail portion of the device, the bottom faces of the left and right plates are common to each of the parties planes, and each plate is provided with a sharp wedge attached to the front of the underlying outer edges of the plate and is installed in the vertical petela on the horizontal plane.

The device comprises a frame 1, is rigidly attached to a vertical knife 2 with thickening at the end of 3, to the vertical knife attached on the principle of the PTO clutch drainer 4. To the frame articulated frame 5 installed in the form of plates seals 6, racks seals 7 and pricipales 8. Rack seal 7 is rigidly attached to the frame 5 in alignment with each other. Seals 6 are attached to the racks alternately with the left and right tilt. To the front of the underlying outer edges of each of the seal 6 is rigidly fastened a sharp wedge 9, mounted in the vertical plane.

The device operates as follows.

When moving the unit (tractor with the proposed device) knife 2 with thickening at the end of the 3 forms in the soil crack extension at the top. The last is called the trapezoidal trench and has a slope of walls close to 45aboutand a depth of about 0.4 m of the Soil in the trench zone due to blunt the cutting angle of the knife 2, retryplease, remains in place, and in the area of the slit is pressed into the wall. Drainer 4 the strip in the zone of movement thickening of the knife 3 production equal to the cross section of tenera 4, freely pulled behind the knife 2. The seals 6, vreis her spongy layer between the bottom faces of the seals and grenera, thereby preventing sagging of the seals on the solid walls of the trapezoidal trench.

This operation destroys the soil, turning it from a tight to a loose condition. The next step relates to the formation of loose soil by means of its compression around tenera, cavity Krotova drains. This is the result of increasing pressure seals 6 down, in one and the other side of tenera 4. This contributes to and tapering to the tail portion of the device seals 6: when the same load on the frame 5, the area of the seals is reduced. The lower faces of the seals being arranged in one plane, produce pressure on the same track, alternating from left to right. The maximum pressure is created in the rear edge of the last seal. Shortly after this drainer 4 is extracted from the already compacted soil around it, leaving it ready mole drains, walls of which are around the perimeter composed of compacted, and therefore resistant to soil erosion. The last operation pricipal 8 podravniat soil on top.

The transfer device from the working position to transport position is done by lifting the hinged system of the tractor frame of the device is casinoi frame chain.

The use of the invention, due to the high ability Krotova drains to blur the water, allows for subsurface irrigation with clean water, disposal of wastewater with simultaneous irrigation and fertilizer topsoil, drainage (drainage) wetlands and increase Blagoveschensky soil by creating additional capacitances formed Cracovie drains.

The device, like its prototype, it is the only one known is able to mould mole drains of a given size, with walls built around the perimeter of the compacted soil and is resistant to scour the water for many years. The economic effect, for example, when subsurface irrigation exceeds the known surface furrow irrigation is not less than one third. (56) USSR Author's certificate N 1569381, CL E 02 In 11/02, 1990.

SUBSTANCE: method involves digging out channel in a single drainage machine pass by plow-type ditcher; dumping dug out fertile ground on channel brows in banks; digging out trench by operative tool of drainage machine; laying drainage pipe and covering thereof with ground; filling channel with fertile ground. Fertile ground layer is loosened before trench digging out along drainage pipe laying axis, wherein width of loosened ground strip is not less than operative tool width. Loosened ground is laid on channel brows. Trench is dug out by chain operative tool of narrow drainage machine performing reverse rotation and extracted ground is placed between trench walls and drainage machine bunker to cover drainage pipe moved into trench by guiding means. Trench is backfilled with ground with the use of two pairs of banks, which provides successive filling trench with ground and loosened fertile ground.

EFFECT: increased efficiency due to prevention of trench wall compaction, reduced power inputs.
