9. The method of using an easily adjustable crop irrigation device according to any one of claims 1-8, characterized in that: Includes the following steps: S1. Sprinkler terminal (3) preset: The connecting frame (32) is threaded to both ends of the cylinder (31) and the rollers (33) are connected to both sides of the sprinkler terminal (3). The distance between the two rollers (33) is adjusted by rotating the connecting frame (32) to a suitable distance and the flat surface (322) is facing the positioning bolt (323). The positioning bolt (323) is screwed in to make it in close contact with the flat surface (322) to complete the fixing of the connecting frame (32). The support plate (324) is attached to one side of the connecting frame (32) and fixed with bolts. The number of connecting pipes (35) connected in the sprinkler terminal (3) is adjusted according to the growth height of the crops planted in the field. The two ends of the connecting pipe (35) are threaded to the sleeve (344) and the guide pipe (36) respectively to complete the assembly and installation of the sprinkler terminal (3). S2. Assembly of the device: Tilt the sprinkler terminal (3) to make the support plate (324) lift up, drag the sprinkler terminal (3) to a suitable position, and set the sprinkler terminals (3) evenly at the field ridges. Connect the hose (39) between the pipes (37) on each sprinkler terminal (3). The two splicing parts (381) are attached to the outside of the bayonet (382) on the pipe (37) and the hose (39). The two splicing parts (381) are fixed together with bolts. Move the water supply terminal (1) to the side of the sprinkler terminal (3) and connect the pump (18) on the water supply terminal (1) to the hose (39) in the same way and connect it to the pipe (37) on the outermost sprinkler terminal (3). After the sprinkler terminal (3) is straightened, the support plate (324) is attached to the ground. Insert the positioning pile (325) at the end of the support plate (324) and wedge the positioning pile (325) into the soil to complete the device fixing. S3. Connection of testing equipment: According to the number of connecting pipes (35) connected in the sprinkler terminal (3), connect the same number of connecting pipes (35) between the test pile (2) and the hanger (23). Connect the connecting wire (202) inside the connecting pipe (35) and connect it to the wind speed detector (24) and the wind speed detector (24) respectively. Connect the connecting wire (202) to the control box (17). Select an open space in the row formed by the water supply terminal (1) and the sprinkler terminal (3) to place the test pile (2). Use the support leg (21) to support the test pile (2). The hose (39) through the test pile (2) is connected to the hanger (23) to complete the assembly of the testing equipment. S4. Irrigation work: Open the top cover (12) of the water supply terminal (1), flip the touch screen (13) to a suitable viewing angle, and input control commands through the touch screen (13) to control the working status of the mixer (16) and pump (18). At the same time, the touch screen (13) displays the detection data of the temperature and humidity detector (22) and wind speed detector (24) in the detection pile (2). Select one of the water inlets (14) and connect it to the external water source through the water pipe. The external water flows through the water inlet (14). 14) The water is introduced into the pump (18) after passing through the storage tank (15). The water is sent out from the output end of the pump (18). During the process of the water flow passing through the series of cylinders (31) and hoses (39), some water is guided by the guide pipe (36) to the connecting pipe (35). The water flows into the base (341) and is sprayed out through the nozzle (342). Due to the inclination of the nozzle (342), the water flows outward and pushes the rotating nozzle (34) to rotate, which plays a role in irrigating the plants around each sprinkler terminal (3). S5. Pesticide preparation and adjustment: According to the needs of pesticide spraying, pesticide is introduced through another water inlet (14). Pesticide and irrigation water are injected together. Pesticide and water are mixed together in the water storage tank (15). The pesticide is sprayed on the crops during the irrigation process. Before irrigation, the temperature and humidity detector (22) and wind speed detector (24) are used to observe the soil temperature, humidity and wind speed in the field through the touch screen (13). The humidity threshold is set according to the local meteorological environment. When the detected humidity exceeds the threshold, the output flow of the pump (18) is reduced, thereby reducing the amount of irrigation water. Conversely, the output flow of the pump (18) is increased. When the wind speed is too high, the irrigation is also reduced or even stopped.
