(5) In the sprinkling irrigation process, the electric air pump 21 and the pneumatic telescopic rod 20 can drive the adjusting piston 9 to move in the water cavity 25 so as to adjust the water pressure in sprinkling irrigation;
(6) After the sprinkling irrigation is finished, the driving motor 16 is closed, the valve on the water inlet pipe 3 is closed or the water source is cut off, at the moment, the upper shell 2 is pulled to move downwards under the action of the first spring 12, and when the pressurizing nozzle 4 is contacted with the lower shell 1, the pressurizing nozzle 4 is extruded into the containing groove 5 against the elasticity of the second spring 13; in the process that the upper shell 2 moves downwards relative to the lower shell 1 or the sleeve 10, the upper shell 2 extrudes water in the bottom of the lower shell 1, impurities such as sand particles deposited at the bottom of the lower shell 1 are pushed into the sewage draining pipe 8, and sewage is drained through the sewage draining pipe 8 to the impurities such as sand particles, so that back flushing of the filter screen 7 is realized.
The invention has upper and lower shells which are arranged up and down, and the first spring is arranged between the upper shell and the lower shell, and the part of the upper shell stretches into the lower shell under the action of the first spring, so that the pressurizing nozzle positioned on the side wall of the upper shell moves into the lower shell, thereby protecting the pressurizing nozzle; the inner side of the lower shell is provided with a baffle plate, and the filter screen is arranged on the baffle plate to filter water flowing into the upper shell after passing through the filter screen from bottom to top, so that sand particles in the water are prevented from blocking the pressurizing nozzle; the filter screen can be cleaned by arranging the blockage cleaning assembly, so that the blockage of the filter screen is avoided, and sand particles are deposited at the bottom of the lower shell; after the sprinkling irrigation is finished, the upper shell is pulled to move downwards under the action of the first spring to squeeze water at the bottom of the lower shell, sand grains on the filter screen are pushed from top to bottom to reversely flush the filter screen, and sand grains deposited at the bottom of the lower shell are pushed into the sewage pipe to be discharged.
