Description

The invention relates to machines for mechanization of irrigation of crops.

A sprinkler machine is known, including a tractor, a two-console truss and a truss stabilization system, in which, in order to stabilize the truss position with longitudinal and transverse tilts of the tractor, especially when it is rotated, the truss is mounted on the tractor with a gimbal, and the stabilization system contains longitudinal and the transverse inclination of the tractor and the hydraulic cylinders controlled by them, acting on the axles of the gimbal suspension (SU, copyright certificate No. 274527. M.cl. A 01 G 25/00. Sprinkler machine / V.A. Anisimov, B.V. Dzyubenko, E .N. Nechaev, V.D. Murashov (USSR) .- Application No. 1296811 / 30-15; Stated January 10, 1969: Publish. June 24, 1970, Bull. No. 21).

The disadvantages of this sprinkler machine are the complexity of the design and the low technical reliability of the water supply pipelines in the farm.

The closest analogue to the claimed object includes a sprinkler installation containing a support element of an irrigation pipeline cantileverly attached to the top of the mast, the free end of which is connected to a land vehicle, in which, in order to expand operational capabilities and increase the irrigation efficiency, the support element is made in the form of a cable mounted with the possibility of axial movement and equipped with a variable length section free from the pipeline (SU, copyright certificate No. 1485459 A1, IPC ⁴ A 01 G 25/09. Sprinkling plant / SV Kibalnikov (USSR) - Application No. 4080272 / 30-15; Declared June 23, 1986; Published 1989, Bull. No. 21).

The design disadvantages of the described installation include design complexity and low operational reliability.

The essence of the claimed invention is as follows.

The problem to which the claimed invention is directed is to simplify the design.

The technical result is a reduction in material consumption.

The specified technical result is achieved by the fact that in the well-known double-console sprinkler unit containing support elements in the form of cables cantileverly attached to the top of the frame and an irrigation pipe connected to the vehicle through a pump installation, according to the invention, the irrigation pipe is made of low-pressure polyethylene in the form of pipe lengths 4-6 m, the ends of which are covered by bandages, and inside the end sections of the pipes there are pipes with flanges, while the pairs of flanges are mutually interconnected elements E through the gasket.

The invention is illustrated by drawings.

Information confirming the possibility of implementing the claimed invention are as follows.

The double-console sprinkler unit includes supporting elements 3-9 in the form of cables and an irrigation pipe 10 cantileverly attached to the top 1 of the frame 2 and an irrigation pipeline 10. The pipeline 10 is connected to the vehicle 11 through a pumping unit 12. The pumping unit 12 is equipped with a floating intake valve 13. On the irrigation pipe 10 there are sprinkler nozzles. Irrigation pipeline 10 is made of low pressure polyethylene in the form of pipe segments 14 with a length of 4-6 m, diameter 120-160 mm. The ends of the pipes 14 are covered by bandages 15 and 16. Inside the end sections of the pipes 14 there are pipes 17 with flanges 18. The pairs of flanges 18 are interconnected by fasteners 19 through the gasket 20. The bearing element 21 is made of a bent C-shaped profile 11.7 m long. Bearing the elements 21 have flanges 22 and 23. The flanges 22 and 23 are mutually connected by bolts located in the holes 24. The supporting elements 21 together with the supporting elements 3-9 form spatial cable-stayed consoles 25 and 26. Irrigation pipelines are laid on the supporting elements 21. Flanges 22 and 23 holds olivnoy conduit 10 in the operating position. The ease of assembly of the flanges 18 with the end sections of the pipes 11 is provided by helical grooves 27 on the surface of the nozzles 17.

Two-console sprinkler unit operates as follows. From the open channel 28 (see FIGS. 1 and 2), the irrigation water is drawn by the floating valve 13. When the pump 12 is running, water is supplied under pressure to the irrigation pipe 10. When the vehicle pressure is 11, sprinkling nozzles on the pipes 14 distribute water in the form of rain drops to irrigated field surface.

The implementation of the irrigation pipeline 10 of the pipes 14, which are used as low-pressure polyethylene, can simplify the design of the sprinkler unit, reduce its material consumption. Pipes 14 are not subject to corrosion. When replacing pipes 14 with sprinkler nozzles, the sprinkler operator proceeds as follows. It releases the fasteners 19 on the flanges 18. Next, the gasket 20 is removed. With a special key, the nozzles 17 are screwed from the ends of the pipes 14 for the flanges 14. This is facilitated by the screw grooves 27 on the surface of the nozzles 17, and the bandages 15 and 16 act as nuts. The replaced pipe 14 is lifted above the bent C-shaped profile of the supporting element 21, and its ends are removed from the holes of the flanges 22 and 23.

The assembly of the irrigation pipeline 10 is carried out in the reverse order without assembly and dismantling of the left and right consoles 25, 26 of the sprinkler unit.

The described set of essential distinguishing features in the claimed object in comparison with the closest analogue allows to achieve a given technical result.
