Abstract

The invention relates to agriculture, namely to the technique of irrigating agricultural crops. The goal is to improve the operating conditions of the machine. The dozhdevalnaya machine consists of self-propelled supports on which water supply is installed up to 2. The rain formers 3, located near the supports, are placed on extensions 4 to both sides of the water supply system. The extensions are connected to the cat with the help of crosses 5. Inside the crosses 5, glasses 7 are installed with windows 8 and 9 symmetrically located in height. The crosses 5 are equipped with a diaphragm actuator connected to the machine running change sensor (DIH). When the DIH machine is moving, the additional rim mounted on the wheel of the self-propelled support wheel opens the power supply circuit of the solenoid valve coil and connects the impulse pipe 16 to the atmosphere. In this case, the glass 7, under the influence of water pressure, rests against the bottom of the restrictive partition 14. In this case, the water through the central nozzle 6 of the cross 5 and the window 8 falls into the left extension 4 and Rain former 3 behind the machine. The invention makes it possible to exclude the soaking of the soil under the self-propelled machine supports and the formation of a rut. 3 il.

Description

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

The purpose of the invention is the improvement of the machine operating conditions.

FIG. 1 shows a schematic of a multi-support sprinkler on a ward, forward, top view; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a diagram of the connection of the impulse tube with the atmosphere.

The multipod sprinkler machine consists of self-propelled supports 1, on which water supply is installed at 2. Near the location of the self-propelled supports 1, low-pressure rain-formers of sectorial action 3 are placed on extension 4 to both sides of the water supply system and connected to it with crosses 5. Inside each central nozzle 6 there is an inverted cup 7 with symmetrically spaced in height in

the vertical plane of the windows 8 and 9. The glass 7 is connected through the rod 10 and the hard center 11 with the diaphragm 12. To install the diaphragm 12 to its original position, a spring 13 is installed at its rear part, supporting one end to the hard center 11, and the other to bounding wall 14.

The over-diaphragm cavity 15 is connected by a pulse tube 16 through an electromagnetic valve 17, the positions of the induction coil 18, the core 19, is moved in the distributor 20 and has an opening 21 in its end part. The core 19 is made with an emphasis 22, between which and the distributor case the spring 23 is installed. The induction coil 18 is connected to its low-voltage power supply system via a sensor 24, detecting a change in the direction of travel of the machine and located on a central support. The sensor 24 is made in the form of an ellipse, which rotates around the axis 25 and has a contact group 26 at the top. It itself is spring-loaded relative to the axis 25 of the telescopic guide 27 and its top touches when the machine moves an additional rim 28 fixed to the wheel of the self-propelled support 1.

The machine works as follows.

When the machine starts moving forward, the sensor 24, touching the rim 28, opens, with its contact group 26, the power supply circuit of the coil 18 of the solenoid valve 17. Then the core 19 under the influence of the spring 23, abutting against the stops 22, pushes all the way into the cavity.

l 20 and connects through a through hole 21 I1 pulse tube 16 with the atmosphere. In this case, the cup 7 under the influence of irrigation water coming from the water supply system 2 and the spring 13 abuts its bottom against the stop - the restrictive partition 14. Water through the central branch 6 of the cross 5, the hollow part of the cup 7 and its window 8 falls into the left extension 4, and after the passage of the self-propelled support, is sprayed with rain-forming agents 3 on the irrigated surface.

When the direction of movement of the machine is changed, the sensor 24, resting with its top on the surface of the rim 28 and compressing the spring-loaded telescopic guide 27, is moved to the opposite position and closes the contact circuit 26 of the coil 18 of the solenoid valve 17 with its contact 26. and overcoming the force of the spring 23, combines the through hole 21 in the cavity of the distributor 20 with the supply of water from the water supply system of the machine 2 and thereby provides its delivery through the impulse tube 16 into the supra-diaphragm cavity 15.

The diaphragm 12, stretched under the pressure of the incoming water and overcoming the force of the spring 13, moves the rigid center 11, and hence the glass 7 in the central nozzle 6 of the cross 5 up to the stop. The water from the water supply system across the ca 2 through the window 9 enters the right extension 4 and is sprayed with rain formers 3 behind the self propelled supports 1.
