[0022] The water inlet assembly 6 includes a water inlet pipe 61 fixedly connected to the top of the outer surface of the water tank 2, and the end of the water inlet pipe 61 away from the water tank 2 is fixedly connected to an externally threaded connecting ring 62, and the outer surface of the externally threaded connecting ring 62 is threadedly connected to a matching connecting cover 63, and the inner top wall of the connecting cover 63 is fixedly connected to a cylindrical filter screen 64, and the outer top wall of the connecting cover 63 is fixedly connected to a water injection cone 65.

[0023] Further Figure 1 and Figure 3 As shown, it is worth explaining in detail that the spray assembly 7 includes a shunt pipe 71 fixedly connected to the center of the top end of the water tank 2, and the outer surface of the shunt pipe 71 is provided with two annular grooves 72 distributed in parallel along the vertical direction, and the outer surface of the shunt pipe 71 is provided with two slots 73 distributed in parallel along the vertical direction, and a rotating ring 74 is rotatably provided in the annular groove 72, and the outer surface of the rotating ring 74 is fixedly connected to a nozzle 75, and a plurality of spray heads 76 are provided at the bottom of the outer surface of the nozzle 75.

[0024] Further Figure 3As shown, it is worth explaining in detail that the spray assembly 7 also includes a slide bar 77 fixedly connected to the bottom of the outer surface of the nozzle 75, a guide groove 78 matching the slide bar 77 is provided at the top of the water tank 2, the bottom of the outer surface of the slide bar 77 is slidably connected to the inner wall of the guide groove 78, a fixing plate 79 is fixedly connected to one side of the bottom of the outer surface of the slide bar 77, a limiting bolt 710 is threadedly penetrated by the top surface of the fixing plate 79, and a plurality of limiting screw holes 711 matching the limiting bolt 710 are provided at the top of the water tank 2.

[0025] Further Figure 1 As shown, it is worth explaining in detail that universal wheels 8 are arranged at the four corners of the bottom surface of the bottom plate 1, and a push handle 9 is fixedly connected to one side of the top surface of the bottom plate 1.

[0026] This solution has the following working process: when it is necessary to irrigate and spray the farmland, first move the device to the river side through the universal wheel 8 and the push handle 9, and then inject the water in the river into the water tank 2 from the water injection cone 65. During this process, the water injection cone 65 is connected with the connecting cover 63, and the water flows into the cylindrical filter screen 64 through the water injection cone 65. The impurities in the water are filtered through the cylindrical filter screen 64, and the filtered water enters the water tank 2 through the water inlet pipe 61. After a period of use, the connecting cover 63 is twisted, and the connecting cover 63 is separated from the external threaded connecting ring 62 through the threaded action, so that the impurities collected in the cylindrical filter screen 64 are cleaned.

[0027] When the water tank 2 is filled with irrigation water, the push handle 9 is pushed to move the device to the target farmland. According to the planting width of the crops in the farmland, the two slide bars 77 are pushed in relative directions. The slide bar 77 moves in the guide groove 78 to drive the nozzle 75 to move. The two nozzles 75 rotate in opposite directions through the cooperation of the annular groove 72 and the rotating ring 74. When the two nozzles 75 rotate to a suitable angle, the limiting bolt 710 is screwed into a corresponding limiting screw hole 711 to complete the limiting fixation of the nozzle 75 and realize the adjustment of the spraying width. Then, the water pump 3 is turned on to input the irrigation water in the water tank 2 into the diversion pipe 71 through the water supply pipe 5. The water flow is pumped into the nozzle 75 through the slot 73 and sprayed through a plurality of spray heads 76 to realize irrigation spraying of the farmland.

[0028] According to the above working process, it can be known that: through the adjustment of the water inlet component 6, the water in the river is injected from the water injection cone 65, and the impurities in the water are filtered through the cylindrical filter 64 to prevent the impurities from clogging the spray component 7 and affecting the normal use of the device. After a period of use, the connection cover 63 is twisted to separate it from the external threaded connection ring 62, and the cylindrical filter 64 is cleaned. The operation is simple and the filtering effect is good, which effectively avoids the problem of poor anti-blocking performance of the irrigation spraying device.

[0029] By adjusting the spray assembly 7, the two slide bars 77 are pushed in opposite directions to slide in the guide groove 78, thereby driving the nozzle 75 to move and adjust the spray width. The limiting bolt 710 is screwed into a corresponding limiting screw hole 711 to limit and fix the nozzle 75. The water in the water tank 2 is transported to the diversion pipe 71 through the water pump 3, and is sprayed out through the several spray heads 76 on the nozzle 75, which effectively avoids the problem that the irrigation spray device is difficult to adjust the spray width.

[0030] Further Figure 1 and Figure 2 As shown, it is worth explaining in detail that one end of the water supply pipe 5 away from the water pump 3 is fixedly connected to the diversion pipe 71, so that the irrigation water in the water tank 2 can be sprayed out through the nozzle 75, and the inner surface diameter of the water inlet pipe 61 is larger than the outer surface diameter of the cylindrical filter screen 64, ensuring that the inner wall of the water inlet pipe 61 will not affect the filtering effect of the cylindrical filter screen 64.

[0031] Further Figure 3 As shown, it is worth explaining in detail that the slot 73 is located on one side of the annular slot 72, which is convenient for water to flow from the slot 73 into the rotating ring 74. The rotating ring 74 is an internal hollow structure, which is convenient for conveying the water passing through the slot 73 to the nozzle 75. The guide slot 78 is set to an arc shape to ensure that the rotating ring 74 can rotate normally in the annular slot 72. The two guide slots 78 are symmetrically distributed and do not intersect, ensuring that the two nozzles 75 will not interfere with each other. A number of limiting screw holes 711 are distributed in a circle with the diverter pipe 71 as the midpoint, so as to better cooperate with the limiting bolt 710.

[0032] In summary: when it is necessary to irrigate and spray the farmland, first move the device to the river side through the universal wheel 8 and the push handle 9, and then inject the water in the river into the water tank 2 from the water injection cone 65. During this process, the water injection cone 65 is connected with the connecting cover 63, and the water flows into the cylindrical filter screen 64 through the water injection cone 65. The impurities in the water are filtered through the cylindrical filter screen 64, and the filtered water enters the water tank 2 through the water inlet pipe 61. After a period of use, the connecting cover 63 is twisted, and the connecting cover 63 is separated from the external threaded connecting ring 62 through the threaded action, and the impurities collected in the cylindrical filter screen 64 are cleaned, thereby effectively avoiding the problem of poor anti-blocking performance of the irrigation spraying device.

[0033] When the water tank 2 is filled with irrigation water, the push handle 9 is pushed to move the device to the target farmland. According to the planting width of the crops in the farmland, the two slide bars 77 are pushed in relative directions. The slide bar 77 moves in the guide groove 78 to drive the nozzle 75 to move. The two nozzles 75 rotate in opposite directions through the cooperation of the annular groove 72 and the rotating ring 74. When the two nozzles 75 rotate to a suitable angle, the limiting bolt 710 is screwed into a corresponding limiting screw hole 711 to complete the limiting fixation of the nozzle 75 and realize the adjustment of the spraying width. Then, the water pump 3 is turned on to input the irrigation water in the water tank 2 into the diversion pipe 71 through the water supply pipe 5. The water flow is pumped into the nozzle 75 through the slot 73 and sprayed through a plurality of spray heads 76 to realize irrigation spraying of the farmland, effectively avoiding the problem that the irrigation spraying device is difficult to adjust the spraying width.

[0034] The water pump 3 can be purchased on the market. The water pump 3 is equipped with a power supply, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.
