The water and fertilizer supply component is used to input fertilizer into the irrigation pipe network, and the irrigation pipe network is used to irrigate the fertilizer. The water and fertilizer supply component includes: a water and fertilizer storage unit, which includes a water source storage device and a fertilizer storage device. The water source storage device is used to store water required for irrigation, and the fertilizer storage device is used to store fertilizer.

[0029] The mixing unit includes a supply device, a mixing tank 1, a stirring device, a filtering and sucking device, and a delivery pipe 2. In this embodiment, the mixing tank 1 is used to mix water and liquid nitrogen fertilizer. The supply device is used to supply water from the water source storage device and fertilizer from the fertilizer storage device to the mixing tank 1 in proportion. The stirring device is used to stir and mix the water and fertilizer in the mixing tank 1. The filtering and sucking device is used to suck the water and fertilizer in the mixing tank 1 into the delivery pipe 2 after filtering. The delivery pipe 2 is connected to the irrigation pipe network.

[0030] The dredging unit is arranged in the delivery pipe 2. The dredging unit includes a closing device, a piston block and a sealing filling device. The closing device is used to drive the piston block to close the delivery pipe 2 when the delivery pipe 2 is blocked, and control the filtering and absorbing device to switch the liquid flow direction to drive the piston block to move in the delivery pipe 2. The sealing filling device is used to use the water and fertilizer in the delivery pipe 2 to seal the connection position between the piston block and the delivery pipe 2, thereby ensuring the sealing between the piston block and the delivery pipe 2 when the piston block moves.

[0031] In the water-fertilizer integrated orchard irrigation system of the present application, fertilization is carried out in the form of sprinkler irrigation. Therefore, the irrigation pipe network includes a main pipe 4 and several branch pipes 5. The main pipe 4 and the delivery pipe 2 are interconnected. The branch pipes 5 are plastic hoses. Each branch pipe 5 is provided with several nozzles 6. The nozzles 6 and the branch pipes 5 are interconnected through solenoid valves. The solenoid valves are closed to cut off the connection between the nozzles 6 and the branch pipes 5. Figure 1 For the convenience of display, only a part of the division 5 is shown.

[0032] The water source storage device includes a water tank 7, which is used to store water required for irrigation. The fertilizer storage device includes a fertilizer tank 8, which is used to store fertilizer. The fertilizer tank 8 stores soluble solids that have been preliminarily dissolved or high-concentration liquid fertilizers.

The delivery pipe 2 is used to connect the suction chamber 1101 and the screw pump 14. Both ends of the delivery pipe 2 are connected to the suction chamber 1101 and the screw pump 14. One end of the stirring main shaft 11 is rotatably connected to the screw pump 14. Therefore, when the stirring main shaft 11 moves, the screw pump 14 will not be driven to move. The screw pump 14 is a single screw pump 14, so it can perform forward and reverse bidirectional output.

[0035] The conveying pipe 2 is symmetrically provided with a slide groove 201, which is used to limit the movement of the slider 15 so that the slider 15 can only move along the slide groove 201.

The slider 15 is connected to the slide groove 201. A rubber sealing ring is provided at the connection between the slider 15 and the slide groove 201, so that the slide groove 201 will not affect the sealing during transmission. A reset spring 16 is provided inside the slide groove 201, and the reset spring 16 is used to drive the slider 15 to reset.

[0036] The closing device includes a closing push rod 17, a magnetic block 18 and a docking sensor 19. The closing push rod 17 is arranged on the fixed part 301. The closing push rod 17 is used to drive. The closing push rod 17 is a DC hydraulic push rod with a waterproof function. The closing push rod 17 is used to drive the moving part 302 to move. The fixed part 301 and the moving part 302 are both provided with a magnetic block 18. The magnetic block arranged on the fixed part 301 and the magnetic block arranged on the moving part 302 can be adsorbed with each other. The docking sensor 19 is used to detect the positions of the fixed part 301 and the moving part 302.

[0037] The sealing and filling device includes a filter membrane 20, a diaphragm pump 21 and an annular water bag 22. The diaphragm pump 21 is arranged inside the movable part 302. The filter membrane 20 is arranged at the liquid inlet end of the diaphragm pump 21. The diaphragm pump 21 is connected to the annular water bag 22. The diaphragm pump 21 is used to input the liquid in the delivery pipe into the annular water bag 22. The annular water bag 22 is arranged on the outside of the piston block. The annular water bag 22 is made of rubber and has certain ductility. One side of the annular water bag 22 is fixedly connected to the fixed part 301, and the inner walls on both sides of the annular bag body 22 are fixedly connected to the movable part 302.

[0038] Working principle: When in use, water and fertilizer are pumped into the mixing tank 1 in proportion through the centrifugal pump 9, and the stirring motor 10 drives the stirring main shaft 11 to move and then drives the stirring blades 12 to mix the water and fertilizer;

[0039] When irrigation is required, the screw pump 14 is started to pump water and fertilizer into the delivery pipe 2, thereby being delivered to the main pipeline 4 and input into the nozzle 6 through the branch pipe 5;

[0040] When dredging is required, the solenoid valve of the nozzle 6 is closed, and then the movable part 302 is driven to rotate by the closed push rod 17, so that the magnetic block 18 provided on the fixed part 301 and the magnetic block 18 provided on the movable part 302 are attracted to each other. After the docking sensor 19 detects that the adsorption is completed, the diaphragm pump 21 will be turned on and the liquid in the delivery pipe 2 is sucked into the annular water bag 22, and a dynamic seal is performed between the delivery pipe 2 and the piston block. After the sealing is completed, the screw pump 14 is reversed to extract the air between the piston block and the screw pump 14; by controlling the screw pump 14 to rotate forward and reverse at equal time periods, the piston block is driven to reciprocate in the delivery pipe 2, thereby generating pressure fluctuations in the main pipeline 4, which will apply pressure to the blockage, loosen it and disperse it, and then open the solenoid valves of the nozzles 6 in sequence until all nozzles 6 can spray water and fertilizer stably.
