Description

 The invention relates to agriculture, namely to technical means for irrigation by sprinkling.

 A two-console sprinkler unit is known, including a three-console three-console farm mounted on a tractor with sprinkler nozzles, it is equipped with self-contained conveyors suspended from a tractor console with reverse drive from a tractor engine (RU, patent N 2047288, IPC A 01 G 25/09. Two-console sprinkler unit // K.V. Huber, G.P. Lampert, M.Yu. Khrabrov, S. G. Kogutov and V. P. Stepanov. Declared April 20, 1993, published November 10, 1995).

 Despite the expansion of functionality, the described sprinkler unit has low technological reliability. The latter is due to the fact that when the irrigation water is taken from an open channel (temporary sprinkler), the mesh of the floating valve is clogged with plant residues and sediments on the surface of the water.

 The closest analogue to the claimed object in terms of features is the well-known, commercially available two-console sprinkler unit DDA-100 VX, including a spatial two-console sprinkler farm mounted on a tractor with sprinkler nozzles, a pump assembly and a suction line with a floating valve (Operating Instructions for the two-console sprinkler aggregate DDA- 100 VX JSC "Volgograd Plant of Irrigation Equipment". -Volgograd-1998. -P. 75.-21 p., Fig. 18).

 The reasons that impede the achievement of the required technical result when using the known device adopted for the closest analogue include the low technological reliability of the unit, caused by clogging with deposits on the surface of the water in the channel of the holes in the grating of the floating valve and short-jet nozzles.

 The invention consists in the following.

 The problem to which the invention is directed is to increase the technological reliability of the sprinkler.

 The technical result is an increase in labor productivity and a uniform distribution of precipitation on the surface of the irrigated area.

 The specified technical result during the implementation of the invention is achieved by the fact that in the known sprinkler unit, including a spatial sprinkler farm mounted on a tractor with sprinkler nozzles, a pump unit, a discharge line, a suction line with a floating valve, the latter is equipped with a sediment discharge device made in the form of a flexible sleeve , for example, a rubberized hose placed by means of brackets on the side walls around the perimeter of the floating valve, while the perforation is made on the flexible sleeve radios, and the sleeve is hydraulically connected through a remote control mechanism of the pressure cavity of the pump assembly; perforations on a flexible sleeve are made in the form of slots or holes.

 Due to the fact that the floating valve is equipped with a device for removing sediment, the above technical result is achieved.

 The invention is illustrated by drawings.

 In FIG. 1 shows a sprinkler, plan view.

 In FIG. 2 - same, right view.

 In FIG. 3 - the same, rear view.

 In FIG. 4-node I in FIG. 1, a floating valve with a device for removing sediment, a plan view.

 Information confirming the possibility of carrying out the invention are as follows.

 The sprinkler unit (Figs. 1-3) comprises a spatial double-hitch truss 2 mounted on a tractor 1 with sprinkler nozzles, a pump unit 3, a pressure line 4, a suction line 5, and a floating valve 6. The floating valve 6 is equipped with a sediment discharge device 7.

 The device 7 (see figure 4) for sediment removal is made in the form of a closed flexible sleeve 8, for example, from a rubberized hose placed by means of brackets 9 on the side walls around the perimeter of the floating valve 6. Perforations are made on the flexible sleeve 8. Perforations on a flexible sleeve are made in the form of slots or holes. The flexible sleeve 8 is hydraulically connected to the low pressure sleeve 10 by a remote control mechanism 11 with a pressure cavity 12 of the pump assembly 3. The remote control mechanism 11 of the device 7 for removing sediment from the walls of the floating valve 6 is made in the form of a shut-off valve body connected by a low pressure sleeve 10 to a floating valve 6 and pump assembly 3. The valve stem is connected to the tractor cabin 1 using a rope 13 with a control lever.

 Sprinkler unit operates as follows.

 Between irrigation, plant residues and leaf-stem mass from nearby irrigated areas and fields are applied to berm, inclined walls and the bottom of the temporary irrigation system by air currents. They form the bulk of sediment. When filling temporary irrigators with water, this mass emerges and forms sediments around the floating valve 6. When the operating mode of the pump unit 3 is established, water is sucked through the grid of the floating valve 6 and enters the suction line 5 into the spiral casing of the pump unit 3. Water from the pump unit 3 under pressure 0.37 ... 0.40 MPa is sent through the pressure line 4 to pipelines of the spatial double-console farm 2. Short-jet irrigation nozzles from 26 to 52 pieces are distributed precipitation in the form of raindrops with a diameter of 2.5 to 5.3 mm. When the remote control mechanism 11 is turned on, part of the water (less than 3-5%) from the pressure cavity 12 along the low-pressure sleeve 10 is directed through the tee into the closed cavity of the flexible sleeve 8. The tee of the device 7 distributes the water flow in two directions. Through slots or openings on the outer contour of the closed sleeve 8, a stream of water in the form of thin jets is directed to the surface of the water in a temporary sprinkler. In the jets, sediments are discharged from the side walls of the floating valve 6. This ensures a continuous and uninterrupted supply of water taken through the mesh to the cavity of the floating valve 6 and to the suction line 5. Under pressure, clean water is sent to the short-jet sprinkler nozzles.

 The described design of the device 7 provides uninterrupted and stable operation of the sprinkler nozzles of the claimed sprinkler unit with a throughput of a temporary sprinkler of 180-200 l / s.

 This is achieved with the simplicity of the design, an increase in labor productivity of at least 9-12% and a uniform distribution of precipitation on the surface of the irrigated field.
