Abstract

This invention relates to agriculture. The aim of the invention is to simplify the design and expand the functionality by adjusting the ratio of water to irrigation and sprinkling. The unit consists of self-propelled water supply 1 in Sa 2 with sprinkling and irrigation working bodies equipped with locking devices 4. The ratio of water to irrigation and sprinkling is provided by the design features of the locking device, which is made in the form of a central nipple with taps 6 and 7 Irrigated working bodies are attached to the central nozzle 5, and working bodies 9 are connected to two symmetrically located lateral branches 9. The central nozzle 5 consists of an elastic diaphragm 10 connected through a rigid center 11 with a spring-loaded rod 12, performed in the tail in the form of a ball. The supra-diaphragm cavity (NP) 15 is connected to the water supply via the catfish or atmosphere by means of the control tube 16 and the control throttle 17. When sprinkling, the oil tank is connected to the start of the water pipe, while the elastic diaphragm under pressure of the water, overcoming the force of the spring, moves the rod until it reaches its extreme position, thus blocking the access of water to irrigation tools. During irrigation, the NP is connected to the atmosphere, the stem is shifted toward the NP, and water enters the irrigation working bodies. In combined irrigation, the elastic diaphragm is placed in an intermediate position by means of the control tube and the throttles. 1 3.p. f-ly, 5 ill. (O (L bond to C35 0

Description

The invention relates to agriculture, namely to the technique of irrigation of agricultural crops.

The purpose of the invention is to simplify the construction of the unit and expand its functionality by adjusting the water content for sprinkling and surface irrigation.

In Fig.1 schematically shows a part of the unit when sprinkling agricultural agricultural crops; FIG. 2 is a section A-A in FIG. 1; on fig.Z - section bb in fig, 2; Fig. 4 shows a part of an aggregate by irrigating agricultural crops using the surface method, node I, section B-B; Fig. 5 - the same, when irrigating agricultural crops in a combined way with different ratios of irrigation water distribution for sprinkling and surface irrigation, node II, section GG.

The unit for irrigation of agricultural crops consists of self-propelled supports 1, on which they are installed in a supplementary one with 2. The locking devices 4, made in the form of a branch pipe 5 with mutually perpendicular branches 6 and 7, are mounted at the location of the water outlet holes 3. Extensions 8 with sprinkling tools are screwed into the taps 6. To prevent division of the flow of water supplied to the sprinkling into parts, the nozzle 7 is offset downward relative to the nozzles 6 and an elastic diaphragm 10 is placed inside it. and I1 through a rigid center with the spring rod 12 extending through the guide 13 and formed in the tail portion in the form of ball order to reduce the length of the spring

14 In the compressed state, it is conical.

The over-diaphragm cavity 15 is connected by a control tube 16, which runs along the entire length of the machine and has a control choke 17 in the initial part, with water supply through the cathode or atmosphere. The inner outlet part of the nozzle 5 is made with a gray tide 18, and on the outer side, irrigation working bodies 19 with pressure suppressors 20 are connected to it.

proceeds with the start of the water line 2. The elastic diaphragm 10 under the pressure of the incoming water, stretching and overcoming the force of the cone spring 14, moves through the rigid center 11 through the guide 13 the rod 12-until it resists the wall of the nozzle 5 and installed in the saddle-shaped tide 18, tightly blocking the access of water to the irrigation workers 19. In this case, the irrigation water supplied to the water supply from C 2 comes through the water outlet 3 and goes to the extension pipes 8 and rain formers 9, afterbirth of the jet is crushed into droplets and is sprayed in the form of rain over the irrigated surface.

For the production of surface irrigation of agricultural crops, each Naddiaphragmatic cavity 15 of the taps 7 by the control tube 16 is connected to the atmosphere through the regulating throttle 17, In this case, the return spring 14, acting on the rigid center 11, takes the elastic diaphragm 10 and, along with it, 13 rod 12 to the side

30 positioning the supra diaphragm cavity 15 until the end spherical part of the stem is installed in the cavity of the nozzle 7. Then irrigation water from the water distribution box

35 2, through the water outlet openings 3, directly enters the ramming channel 5 of the coil 5, and then into the cavity of the flexible irrigation working body 19, dragging along the ground, where due to

40 of the installed extinguisher 20 of the head, it loses its energy and, close to zero speed, flows along the walls to the soil surface, thus irrigating agricultural crops in a way noBepxHocTHbrti.

For the implementation of the combined irrigation of agricultural crops with different ratios of irrigation water distribution for sprinkling

50 and surface watering naddiafragmen-. to the cavity 15 of the nozzle 7 by the control tube 16 through the regulating choke 17, set at a predetermined mark, is again connected to the beginning

55 of the water supply system 2 installed on the supports 1. Then, under the pressure of the incoming water, the elastic diaphragm 10 partially stretches and overcomes the force of the spring 14, moves the rod 12 through the direction 13 until the bar above the diaphragm is balanced by the force developed The spring 14 and the rod 12 will stop, partially blocking the spherical shape of the passage section of the nozzle 5. In this case, the water from the water conveyor 2 through the water outlet 3, as defined by the mine, the easily streamlined shape of the ball bochie bodies 19, and the other remaining backed end of the stem enters the tubes fS, then extenders dozhdeobrazovateli 8 and 9, it is crushed to the last drop.
