Abstract

The invention relates to agriculture and can be applied to sprinkling and irrigation machines for applying fertilizers and other chemicals simultaneously with irrigation water. The aim of the invention is to reduce energy losses. During direct hydraulic impact in cylinder 10, the pressure difference in cavities A and B of the cylinder moves the diaphragms of the discharge chamber 4 and return 5 to the upper position, while fertilizer is pumped out of the pump through pipeline 3 to the discharge pipeline 16. With reverse pumping of the pump membrane move down, while the fertilizer from the tank 1 is sucked into the pump through the pipeline 2. 1 sludge. / 7 cl J th (/ 7 with HcE 00 th Hch

Description

The invention relates to a seed farm and can be applied to sprinklers and irrigation machines for applying fertilizers or other chemicals simultaneously with irrigation water.

Tse.: One of the inventions is to reduce energy losses.

The drawing shows a fertilizer for sprinkling and irrigation machines.

11odkormtsiktsy contains a capacity of 1 dl / kndky fertilizers, suction 2 and injection pipelines 3, a diaphragm pump containing two chambers - pressure 4 and return 5, check valves 6 and 7, drainage holes 8, rod 9 and a hydraulic percussion drive. The latter consists of a cylinder 10, impact clan 1 with a n. Circumference 12, a saddle 13, divided by a nilindra K) into two sections A and B, pipelines 14 to 15. The drive is connected to the pressure line 16 through an indirect pipeline 17 and taps 18 and nineteen.

The working nroness starts from opening the taps 18 and 19. At the same time, the water from the pressure pipe 16 and line 17, to the cylinder 10, to the cylinder 10 through the force of the spring 12, the shock valve kolapap 11 and September 13 returned with increasing speed to the pressure line 16. When a certain CKOpocTHOi o head is reached, the total pressure on the impact valve 11 overcomes the resistance G2 and closes. Owing to the sharp ocTaiiOBKH of the water jute, 1-hydraulic shock is used. In this case, a high-pressure zone appears in the A Qi; | Indra 10 floor, and a low pressure zone in the B B floor, caused by a sharp cut-off of the water flow. These pressures are distributed through pipelines 14 and 15 into injection 4 n return 5 chambers. As a result of the difference in pressure of water on the membranes of these chambers and S15NaZN by their means of the rod 9 - EXIT POSITION, the displacement of the membranes into the upper layer is not. When this occurs, the pressure of the solution of mineral fertilizers over the membrane of the injection chamber 4, after unloading water from tank 1 but suction head 2) 2, is increased. 2.

the solution through the check valve 7, the discharge pipe 3 is squeezed into the cavity B of the cylinder 10 and then with a water flow through the pipe 17 enters the pressure line 16. At the end of the direct water hammer, a reverse water shock occurs. In this case, a high pressure zone arises in cavity B of cylinder 10, and a low pressure zone in cavity A. These pressures are distributed through conduits 15 and 14 to return 5 and injection 4 chambers. As a result of the pressure difference across the membranes of these chambers and their connection by means of the slider 9, they are lowered to the lower position. At the same time, a discharge is created above the membrane of the discharge chamber 4, as a result of which the fertilizer solution from the tank 1 but to the suction pipe 2 through the check valve 6 enters the pump. When the water strikes back and the spring 12 acts, the shock valve 11 opens. Then the cycle of operation is repeated. The dose of the fertilizer solution supply to the water is set by cranes 8 and 19. After they cross-section, they regulate the flow rate of the water in the parallel pipe S7 and, consequently, the frequency of the cycles and the force 1 of the impact force.
