Abstract

This invention relates to agriculture. The purpose of the invention is to simplify the remote start of the machine. The pumping system consists of a hydraulic shut-off valve at the machine inlet, controlled by a hydraulic relay, connected to a control tube, passing through all supports and connected to the end of the pipeline of the machine through a check valve and an adjustable choke. On the control tube there are actuating valves, interacting with the stops of the synchronization mechanism of the supports. A hydraulic valve connects the pressure pipe to the control tube. The membrane and the 1st hydraulic actuator of the hydraulically controlled valve is connected to the upper cavity of the hydraulic actuator of the valve. On the control tube, shut-off valves are installed in front of each actuating valve. After elimination of the malfunction, the remote start of the machine is carried out by shut-off valve of the open actuating valve of the control tube section located behind the open actuating valve. 1 il.

The invention relates to agriculture, namely, to automatic protection systems for self-propelled multi-support sprinkler machines.

The purpose of the invention is to simplify remote start.

The drawing shows schematically the emergency protection system of a multi-support sprinkling manshna.

The emergency protection system of the rain machines consists of the valve 2 installed on the pipeline 1 with hydraulic actuator 3 controlled by the hydro relay 4, the actuator 5 of the relay, the control pipe 6 fed from the pipeline 7 doz / s, the final machine at the last support through an adjustable throttle 8 and check valve 9, connecting successively operating actuating valves Yu, interacting with the stops 1I of the mechanism 12 of the synchronization of the supports, normally open shut-off valves 13, installed in the superfluous control tube 6 in front of actuating valves -10, a hydraulically adjustable valve 14 connecting the pressure pipe 1 to the control tube 6. The hydraulic actuator 15 of the valve 14 is connected to the hydraulic relay and the upper cavity of the hydraulic actuator 3.

The emergency protection system multi-support sprinkler works as follows.

In the event of unacceptable bending of the pipeline 7 of the sprinkler, the actuating valve 10 is opened on the corresponding faulty support. At the same time, water from the control tube 6 is discharged into the atmosphere, as a result of which the switching of the hydrorelay 4 occurs; water enters the piston cavity of the hydraulic actuator 3 by closing the closure organ 2.

After closing the closure member 2, the pressure in the above-piston cavity of the hydraulic actuator 3 increases, causing an increase in pressure in the hydraulic actuator 15 of the valve 14, thereby ensuring its opening. As a result, water is supplied from the discharge pipe 1 to the control tube 6 and through the open executive valve 10 to malfunctioning trolley in the atmosphere. Due to this, the hydrorelay 4 cannot switch and open the stop valve.

After the malfunction of the sprinkler truck has been eliminated, the remote start of the machine is carried out by separating (disconnecting) the open actuating valve 10 of the section of the control tube 6 located behind the open actuating valve. This is done by closing the shut-off valve 13 in front of the open actuation valve 10. As a result, the pressure in the control tube increases and causes the switching of the hydro-relay 4, thereby ensuring the opening of the shut-off member 2 and closing of the hydraulically-controlled valve 14. Opening the shut-off member 2 provides water from the pipeline of the machine through the check valve 9 and the regulator, the choke 8 to the section of the control tube 6, disconnected from the pressure pipe 1. As the pipeline 7 of the sprinkler is leveling The pressure in the control tube rises in the area that was disconnected from the discharge pipe, since the actuating valve 9 automatically closes.

After that, the locking valve 13 is opened, i.e. Connecting both portions of control tube 6 together. The machine is in automatic mode.
