The technical field

The invention relates to agriculture, in particular to tools for cutting temporary irrigation network, and can be used to open the berm and the overlap of the ground of the temporary fill.

The level of technology

A device for supplying water into the band, consisting of the sprinkler installed at him across devices (Sandor) and culverts (firecrackers), feed water into strips (korshikov A.A. Device temporary irrigation network. - M.: Kolos, 1971. .38-39.

The disadvantages of this device are the high cost of capital investment, low level of mechanization of irrigation and the presence of hydraulic structures that impede the implementation of agricultural activities on the field.

Closest to the proposed technical essence is a device for irrigation of the bands with the help of a bulldozer, selected as a prototype, including a bulldozer with a lift cylinder shield (dozer shovel). To supply water from a temporary fill in band bulldozer moves at an angle of 30-35° temporary fill, cuts off the berm fill and cut the primer overlaps the fill, and the water from the sprinkler via cut "propane" goes to the band ((AV Mechanized irrigation furrow with application of bulldozer /Hydraulic engineering and land reclamation, No. 5, 1975. S-83).

Not what atcom this device is the bulldozer is moving strip, in which water flows, this breaks down stripes, ridges and furrows in the double pass of the tractor for cutting the berm and return the tractor to a new position.

Disclosure of inventions

The invention aims to remedy these disadvantages.

The technical result improved quality open berm fill, as well as reducing the cost of running irrigation lines.

This is achieved in that the device comprises a frame hinged side of the tractor and lowered using a hydraulic cylinder on the opposite side of the tractor toward the time of the fill. To the Central part of the shield device pivotally attached to the piston rod of the hydraulic cylinder. The shield is made of two unequal length parts.

Brief description of drawings

1 shows a device for supplying water from a temporary fill in the band, hung on universal tractor, front view; figure 2 is a top view before opening the berm fill; figure 3 is a top view of the final step of opening the berm fill.

The implementation of the invention

Device for supplying water from a temporary fill in a strip consists of a frame 1, a lift cylinder device 2, a shield 3, pivotally connected with the rod of the hydraulic cylinder 4. The frame of the device is hung on the side spar tractor and have the opportunity to climb with the help of the hydraulic cylinder 2, this allows the tractor to the device to be on the opposite side of the fill from the pour strips and cut fill cut off the ground without breaking the strip and vodohranilisha rollers. For qualitative overlap the shield is made of two unequal length parts, the hinge 5 is attached to the frame of the device. The shield is attached compression spring 6 and the rotation limiter shield 7 ensuring the return of the shield after completing the overlapping position perpendicular to the frame of the device.

The device operates as follows.

After cutting the temporary fill the tractor with side hinge device arrives as close as possible to the berm fill, pushes the piston rod of the hydraulic cylinder 4 to its full length, thus the spring 6 shield 3 is installed parallel to the tractor (to fill). The lift cylinder 2 shield 3 is lowered onto the field on the other side opposite berm fill.

When turning on the hydraulic cylinder 4, the movement of the shield begins with the lower part of the side shield (due to the action of forces of resistance to cutting of the soil), which moves soil from the berm to the side of the fill. When you come to the stop 7, the side stops and moves only other part of the shield. When this movement takes place progressively over the rod of the hydraulic cylinder and a circle with the center at the end of the stroke limiter lower the Asti shield. The ground, cut off from a large berm shoulder shield, served in the fill and simultaneously pressed against the part of the soil, which shifted the shield of his short part. Through this movement the soil cut from the berm, qualitatively overlaps the fill, and propane in the berm for the passage of water from the sprinkler in the band get more fill. Due to this, the speed of the water in the closure channel does not exceed the speed of water in the sprinkler and intensive erosion of berm fill does not occur.

The invention compared with the prototype has the following advantages:

the tractor during operation is located on the opposite side of the fill from the pour strip, this allows you not to break the band and vodohranilisha rollers;

- savings in investment costs due to the use of mobile devices hinged on universal tractor;

this process has a high productivity by 100% mechanization;

environmental factor is provided by the opening of the closure channel berm larger than the width of the fill, and therefore, the speed of the water in the closure channel does not exceed the speed of water in the sprinkler, and intensive erosion of berm fill does not occur. In addition, due to the rotation of the shield is provided by soil compaction, overlying fill.

The feeder is of the odes of temporary fill in lane consisting of a frame with a hitch on the tractor, lift cylinder and shield for blocking the nozzle, characterized in that the shield is made of two unequal length parts that are attached with hinges to the frame of the device, and the shield is provided with a compression spring and a rotation limiter shield, the latter being made with the possibility of a return of the shield after completing the overlapping position perpendicular to the frame of the device.
