[0025] To enable those skilled in the art to better understand the technical solution, the present invention will be described in detail below with reference to the embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0026] like Figures 1-4 As shown, the specific solution of this embodiment is as follows: an integrated water and fertilizer irrigation system, including a main pipe 10, several branch pipes 11 connected to the main pipe 10, and water outlet pipes 12 connected to the branch pipes 11. A sprinkler head 13 is provided at the top of the water outlet pipe 12. The sprinkler head 13 is mainly used for sprinkler irrigation and can be used when the crops are growing small. The water outlet pipe 12 is also provided with a watering head 14 close to the ground. The watering head 14 is mainly suitable for irrigation after the crops have grown tall. This can ensure that water and fertilizer seep into the ground and avoid excessive spraying on the leaves, thereby reducing evaporation and other phenomena. The sprinkler head is matched with the manual irrigation interface to adapt to the complex terrain of mountainous areas, ensure that each area can receive sufficient water and fertilizer supply, promote plant growth, and improve yield and quality.

[0027] Specifically, there are 10 supervisors. Branch pipe 11 is Water outlet pipe 12 is Stainless steel pipes, with the main pipe 10 and branch pipes 11 arranged in a tree-like structure, as shown in the attached diagram. Figure 1 As shown; the feed end of the main pipe 10 is connected to the water storage tank 21. The main pipe 10 passes through the pump house 22. The pump house 22 is equipped with a drive source to drive the water flow. In this embodiment, the drive source is a pump. When the pump is started, the water in the water storage tank 21 can be introduced into the main pipe 10, branch pipe 11 and outlet pipe 12 for irrigation. When fertilizing, the fertilizer only needs to be put into the water storage tank 21 and stirred with water to form water fertilizer, thereby achieving rapid fertilization.

[0028] The water outlet pipe 12 is further provided with a control valve 15 between the sprinkling head 13 and the irrigation head 14, so as to control the water outlet of the sprinkling head 13. The control valve 15 is connected with a controller, specifically, a PLC touch screen integrated machine core is arranged. A high-precision pressure sensor is further arranged on the water outlet pipe 12. In order to have uniform water outlet at different heights, the pressure set by the pressure sensor of the water outlet pipe 12 at the highest position is generally used as the standard for opening of the control valve 15. That is, when the pressure of the pressure sensor on the water outlet pipe 12 at the highest position reaches the standard, all the control valves 15 are opened, so that crops at all positions can be irrigated. The valve of the irrigation head 14 can be controlled by the controller or manually controlled, so as to adapt to different needs.

[0029] As shown in Figure 1 , 2 , as a preferred mode of the above embodiment, the bottom of the water outlet pipe 12 is communicated with a water collecting part 16. Specifically, the water collecting part 16 includes an outer shell body 161 and an inner box 162. The outer shell body 161 is made of cement, and the inner box 162 is made of stainless steel. The bottom of the water collecting part 16 is communicated with a connecting pipe 163. The connecting pipe 163 is provided with a connector 164 connected with the branch pipe 11. A filter screen is arranged in the connector 164. Therefore, during installation, only the connector 164 and the branch pipe 11 need to be connected. The filter screen in the connector 164 can filter impurities in the water to avoid blockage in the water collecting part 16. The connecting pipe 163 penetrates the outer shell body 161 and the inner box 162. A one-way valve is arranged at the end of the connecting pipe 163 extending into the inner box 162. The one-way valve can prevent the water in the inner box 162 from flowing back to the branch pipe 11, so as to keep the water in the water collecting part 16 sufficient. During irrigation and spraying, the water can be quickly sent outwards.

[0030] As shown in Figure 3 , 4 , as a preferred mode of the above embodiment, the main pipe 10 is provided with a sleeve 17 communicated with the branch pipe 11. A valve core 18 for preventing water backflow is rotatably arranged in the sleeve 17. The rotation shaft of the valve core 18 is eccentrically arranged (as shown in Figure 3 ). The valve core 18 has a plate-shaped structure. The outer side of the sleeve 17 is provided with a reset assembly 20 for driving the valve core 18 to rotate and reset. Specifically, the reset assembly 20 is a spring assembly or a torsional spring assembly.

[0031] The sleeve 17 is internally fixedly provided with a blocking piece 19 for limiting the rotating position of the valve core 18, which is a baffle plate arranged to avoid the sleeve 17 being opened by the excessive rotation of the valve core 18, and the valve core 18 is mainly arranged to block the water in the main pipe 10 after the water supply is stopped, so as to prevent the water from flowing back to the water storage tank 21, thereby the water can be quickly led out in the next water supply process, the waiting time is reduced, and the cost is saved.
