The invention relates to agriculture, in particular to techniques for irrigation of cultivated crops.

Known front sprinkling unit, placed on a vehicle and equipped with a pumping unit, trunks with sprinkler devices kratkosrochnogo and delestrange type (SU, USSR author's certificate No. 71136, a 01 G 25/09, 1959).

The disadvantages of this sprinkler unit is the low productivity.

Also known front sprinkler unit comprising a pumping installation of the articulated sections of the pipeline with a sprinkling apparatus kratkosrochnogo and delestrange type, hanging banners from the top and lateral directions (GB, UK application No. 1435999 And 01 G 25/09, 1973). This unit we have adopted as a prototype.

The disadvantages described front sprinkler unit is unstable position of the articulated sections of the pipeline due to the rocking of stretching in the lateral and vertical directions.

Task to be solved by the claimed invention is directed, the improvement of the dynamic characteristics of front sprinkler Assembly.

The technical result is to simplify the design, reduce metal consumption and improving the quality of irrigation.

This technical result d is attained, however, that famous front sprinkler unit comprising a pumping installation of the articulated sections of the pipeline with a sprinkling apparatus kratkosrochnogo and delestrange type, suspended on the tractor stretching from the upper and lateral directions, according to the invention, each section of the pipeline is additionally connected with the upper and lateral stretching of a closed branch of rope, one end of which is placed in the tapered hole of the bracket of the pipeline and the other end of the rope - locking device fixed positions, placed in a pair of U-shaped brackets of the pipeline.

Due to the fact that in each section of the pipeline top and side banners interlocked with the pipeline, achieved a stable position front sprinkler on the tractor and this is achieved by increasing the dynamic characteristics under irrigation sprinkler devices short - and delestrange type.

The invention is illustrated figure 1-7.

Front sprinkler Assembly includes a pump unit 1 of articulated sections 2 pipeline 3 with sprinkler devices 4 and 5 kratkosrochnogo and delestrange type. Pipeline 3 with articulated sections 2 and sprinkling devices 4 and 5 is suspended on the rack 6 of the tractor 7 on the stretch marks 8, 9 and 10 with the upper and side directions. Each articulated section 2 pipeline 3 is additionally connected with stretch marks 8 - 10 top and lateral directions of a closed branch of the rope 11. One end (12) of the rope 11 is placed in the tapered hole of the bracket 13 of the pipeline 3. The end 12 of the rope 11 has a thickness in the form of a truncated cone. The other end (14) of the rope 11 is mounted in the cavity of the block 15 fixed positions. The locking device 15 is placed in a pair of U-shaped brackets 16 of the pipe 3 (see Fig 1 and 2).

The locking device 15 (see figure 3-7) fixed positions of the rope 11 is made in the form of a pair of diametrically oriented hooks 17 and 18. The hooks 17 and 18 simultaneously paired with a pair of U-shaped brackets 16 of the articulated section 2 pipeline 3 and mounted with in what zmoznostjo dismantling on the outer surface of the housing 19. In the housing cavity 19 is covering the surface of the rope stopper 11. The stopper contains coaxially and sequentially mounted on the end 14 of the rope 11 in the housing cavity 19 with a tapered surface of the socket down the hollow stem 20, the ball elements 21, 22 and 23, the elastic element 24 and the threaded cap 25 in the bottom part of the housing 19. Ball elements 21-23 are placed in radial grooves 26 of the hollow shaft 20 and connected with the conical surface of the housing 19 and the rope 11.

Front sprinkler Assembly operates as follows.

When running the motor installing the tractor 7 pump unit 1 floating through the valve from an open sprinkler water is sucked and work under pressure in a sprinkler apparatus 4, and 5 short - and delestrange type. When forward movement of the tractor 7 on irrigated land is evenly distributed layer of sediment in the form of drops of rain. The resistance movement front sprinkler unit according to the technological road along the open fill regardless of the unevenness of the road and the wind loading on the articulated sections 2 and pipe 3 is achieved by the fact that stretch marks 8, 9 and 10 in the vertical and lateral directions optionally mutually linked by ropes 11 in each section. When the slack of the articulated section 2 pipeline 3 transfer end 14 of the rope 1 from the housing 19 blokiratora mutually closer stretch marks 8-10. This creates resistance mutual positions between the marks 8-10 and pipeline 3. Tractor 7 together with the stand 6 and articulated sections 2 get hard mutually balanced position. For tensioning of the rope 11 to the operator of the sprinkler unit, simply pull the end 14 of the rope 11 in the direction of the pipe 3. The rope 11 with the hollow shaft 20 and the spherical elements 21-23 will move in a conical socket housing 19, compressing the coils of the elastic element 24. Further movement of the rope 11 causes the ball elements 21-23, moving in the radial slots of the hollow shaft 20, are exempt from the contact voltage with the end 14 of the rope 11. The end 12 of the rope 11 due to its conical thickening is held in a stationary position in the tapered hole of the bracket 13. In the trunk of the rope 11 is selected as the slack in the stretch marks 8-10. The articulated section 2 pipeline 3 is horizontal, without deflection, position.

Thus, the rigid position of the articulated sections 2 pipe 3 with respect to the rack 6 of the tractor 7 and this ensures the stable operation of the sprinkler devices 4 and 5 and the corresponding quality of the rain.
