SU1387922A1 - Generator of command pulses for closed irrigation system - Google Patents

Abstract

The invention relates to agriculture and can be used to form command pulses for switching sprinklers during group work and for pulsing the input of fertilizer solutions into irrigation water. The purpose of the invention is to simplify the design. The command pulse generator includes a pressure pipe 35, a shut-off valve 44 with hydraulic actuator 40 and a time relay. The time relay consists of a hydraulic cylinder 1, a piston 5, two rods 7. The ends of the rods 7 are equipped with adjustable faceplates 8 and 9. The plates 8 and 9 are kinematically connected to the switch 19. The hydraulic cylinder 1 and the hydraulic actuator 40 of the valve 44 through the switch 19 are hydraulically connected to The discharge pipelines of the water line 35 of the network 45. The throttles 30, 31, 32 are installed on the discharge and discharge channels 38 and the switching channels 37. The generator of command pulses makes it possible to vary the time of alternating cycles within wide limits. At the same time, by increasing the number of channels on the switch 19 for the liquid to the hydraulic actuators 40, it is possible to regulate the opening time of the outlets on the network 45 according to the scale of the chokes 30, 31, 32. 3 Il. & (L

The invention relates to agriculture and can be used to form command pulses for switching sprinklers during group work and for pulsed input of fertilizer solutions into irrigation water.

The aim of the invention is to reinforce the structure.

51, 52 and a lid 53. An arrow 54 is fixed on the rod of the throttle needle.

The command pulse generator works as follows.

The diagram of the device shows the position of the piston 5 of the hydraulic cylinder 1 after switching the plunger 18 of the switch 19 to the subsequent operating cycle, during which the liquid under pressure flows through the choke 31 through the opening 20 to the channel 37 and

command pulse generator circuit; on Yu cylinder under the piston. At the same time, the drain 2 - throttle scale; in fig. 3 - mouth-bones from the cylinder occur along channel 36

through the plunger 18 openings 20-22 for draining. Under the pressure of the fluid entering the hydraulic cylinder, the piston 5, reaching the cover 2 of the hydraulic cylinder, faceplate 9 on the reverse side of the cylinder, pressing the rocker 14, switches the plunger switch to discharge water into the hydraulic cylinder through the throttle 30 through the open plunger bypass

7 have outward ends, where at the 20th channel through holes 23-25. In addition, each of them is movably mounted plan-liquid channel 36 will flow into

washers 8, 9 with springs 10, P. On the hydraulic cylinder with its reverse side and

the brackets are fixed to the brackets 12, 13 with rocker arms 14, 15. The rocker arms, with their ends alone, go under the ends of the faceplates - ,, -

the stem, and the others are connected by studs 16, the piston in one direction is 17 with the plunger 18 of the switch 19. Plun-depending on the rotation of the needle 48 choke.

In the other direction of motion of the piston, it is possible to set another cycle time with another choke.

The command pulse generator for closed irrigation systems contains a time consisting of hydraulic cylinder 1, its end covers 2 with seals 3 at the ends of the cylinder, and seals 4 cylinder rods.

The piston 5 of the hydraulic cylinder has elastic sealing rings 6, and its rods

move it the other way.

Duty cycle time when driving

The switch port has holes 20-22 coaxially drilled with the housing, and additional holes 23-25 are drilled in the housing so that when switching the plunger it is provided with a lock consisting of screw 26, spring 27 and metal ball 28, and seals 29. Switching The heater is connected to the throttles 30-32, and the throttles of the three-channel manifold 33 are connected to the filter 34, which is connected to the pressure pipe 35.

A switch with a hydraulic cylinder of the plane, it is possible to change the opening time of the network 45.
