Gears 24 are fixedly provided on the surface of the spray pipe 22 and on the inner sides of the two protective frames 21. Two slide rails 25 are fixedly provided on the top of the mounting base 1. Gear plates 26 are slidably connected to the surfaces of the two slide rails 25. The two gear plates 26 are respectively engaged with the two gears 24. Two electric cylinders 27 are fixedly provided on the top of the mounting base 1 and on the opposite side of the two gear plates 26.

Please combine Figure 3 and Figure 4 : Start the two electric cylinders 27, and the two electric cylinders 27 extend to drive the two gear plates 26 to slide forward on the surface of the slide rail 25. The two gear plates 26 move forward and drive the two gears 24 to rotate counterclockwise. The counterclockwise rotation of the two gears 24 drives the spray pipe 22 and the atomizing nozzle 23 to rotate counterclockwise. When the two electric cylinders 27 retract, they drive the two gear plates 26 to move backward on the surface of the slide rail 25. The two gear plates 26 then drive the two gears 24, the spray pipe 22 and the atomizing nozzle 23 to rotate clockwise; Furthermore, when the two electric cylinders 27 reciprocate and extend, they drive the two gear plates 26 to slide back and forth on the surface of the slide rail 25. The two gear plates 26 move back and forth, thereby driving the two gears 24 to reciprocate. The reciprocating rotation of the two gears 24 drives the atomizing nozzle 23 to swing back and forth through the spray pipe 22, thereby improving the application effect of foliar fertilizer. Preferably, the other end of the delivery pump 28 is connected to the mixing box 61 through a pipeline, and the water-soluble fertilizer in the mixing box 61 is delivered to the spraying pipe 22 through the delivery pump 28; The backwash mechanism 3 includes a flushing pump 31, a guide plate 32 and a transverse plate 33.

The movement of the horizontal plate 33 drives the adjustment frame 35 and the flushing nozzle 36 to move downward; Furthermore, when the electric cylinder 27 is extended and the atomizing nozzle 23 is adjusted upward to a vertical position under the action of the gear plate 26 and the gear 24, the electric telescopic rod 37 is retracted to align the flushing nozzle 36 with the atomizing nozzle 23, and the flushing pump 31 is started. The flushing pump 31 flushes the water in the water tank 7 through the flushing nozzle 36 toward the atomizing nozzle 23, thereby backwashing the atomizing nozzle 23; Preferably, the other end of the flushing pump 31 is connected to the water tank 7 through a pipe, and a plug is provided at one end of the spraying pipe 22.

[0023] In this embodiment, unlike the existing fertilizing device, the fertilizer applied by this fertilizing device is a mixture of manganese salt and calcium-magnesium mixed salt. After the calcium-magnesium fertilizer is sprayed, the atomizing nozzle 23 is easily clogged. This device extends through the electric cylinder 27, and with the cooperation of the gear plate 26 and the gear 24, the atomizing nozzle 23 is adjusted upward to a vertical state. The flushing nozzle 36 can be aligned with the atomizing nozzle 23 by retracting the electric telescopic rod 37, and the flushing pump 31 is started. The flushing pump 31 flushes the clean water in the water tank 7 through the flushing nozzle 36 to the atomizing nozzle 23, and backwashes the atomizing nozzle 23 to avoid fertilizer crystallization and blockage, thereby improving the uniformity of foliar fertilizer application to crops, avoiding excessive fertilizer localized on the leaves causing leaf burn, or insufficient application causing nutrient deficiency in the crops.

The upward movement of the pumping rod 53 drives the piston 52 to slide upward inside the suction tube 51, thereby transporting the clean water in the suction tube 51 to the cleaning nozzle 56 through the drain pipe 55. The cleaning nozzle 56 then sprays clean water to clean the detection part of the soil rapid tester 41. Preferably, one-way valves are provided on the surfaces of the water pumping pipe 54 and the drainage pipe 55 .

[0025] In this embodiment, when the slider 34 moves downward, it will also drive the driving plate 42 to move downward. The driving plate 42 moves downward to press the adjustment block 44 downward. The adjustment block 44 moves downward to drive the mounting bracket 46 and the soil rapid measuring instrument 41 to move downward, so that the bottom end of the soil rapid measuring instrument 41 is inserted into the soil, and then the soil moisture, pH value, calcium and magnesium content and other soil trace elements are detected. The concentration of water-soluble fertilizer is configured based on the calcium and magnesium content obtained by the detection, so as to accurately meet the needs of crops and avoid waste of resources or side effects caused by blind fertilization. When the adjustment block 44 is reset, it will drive the pumping rod 53 and the piston 52 to move upward, so that clean water is sprayed out from the cleaning nozzle 56 to clean the detection part of the soil rapid measuring instrument 41, so as to improve the accuracy of the next test data.

[0031] Please refer to the Figures 1 to 13 The working principle of the intelligent fertilizing device provided by the present invention is as follows: Step S1: Move the device to the work site, then start the two electric cylinders 27. The two electric cylinders 27 extend to drive the two gear plates 26 to slide forward on the surface of the slide rail 25. The two gear plates 26 move forward to drive the two gears 24 to rotate counterclockwise. The counterclockwise rotation of the two gears 24 drives the spray pipe 22 and the atomizing nozzle 23 to rotate counterclockwise, and the atomizing nozzle 23 is adjusted upward to a vertical position. The two electric telescopic rods 37 are activated. The retraction of the two electric telescopic rods 37 drives the horizontal plate 33 to move downward, causing the two sliders 34 to slide downward on the inner side of the guide plate 32. The movement of the horizontal plate 33 drives the adjustment frame 35 and the flushing nozzle 36 to move downward. The flushing nozzle 36 is aligned with the atomizing nozzle 23. The flushing pump 31 is activated. The flushing pump 31 flushes the water in the water tank 7 through the flushing nozzle 36 to the atomizing nozzle 23, thereby backwashing the atomizing nozzle 23. In step S2, when the slider 34 moves downward, it simultaneously drives the driving plate 42 downward. The driving plate 42 moves downward to press the adjustment block 44 downward. The adjustment block 44 moves downward to drive the mounting bracket 46 and the soil rapid tester 41 downward, so that the bottom end of the soil rapid tester 41 is inserted into the soil, thereby detecting the soil moisture, pH value, calcium and magnesium content, and other soil trace elements. When the adjustment block 44 moves downward, it simultaneously drives the pumping rod 53 downward. The downward movement of the pumping rod 53 drives the piston 52 to slide downward inside the suction pipe 51, thereby pumping the clean water in the water tank 7 into the suction pipe 51 through the water pumping pipe 54. Step S3: After backwashing the atomizing nozzle 23 is completed and soil test data is obtained, the electric telescopic rod 37 is controlled to reset the slider 34 and the cross plate 33. When the slider 34 moves upward, the drive plate 42 removes the pressure on the adjustment block 44. Under the action of the spring 45, the adjustment block 44 moves upward. The upward movement of the adjustment block 44 drives the mounting bracket 46 and the soil rapid tester 41 upward, so that the soil rapid tester 41 is separated from the soil. When the adjustment block 44 moves upward, it simultaneously drives the pumping rod 53 upward. The upward movement of the pumping rod 53 drives the piston 52 to slide upward inside the suction tube 51, thereby transporting the clean water in the suction tube 51 through the drain pipe 55 to the cleaning nozzle 56. The cleaning nozzle 56 then sprays clean water to clean the detection part of the soil rapid tester 41. Step S4: After the soil rapid measuring instrument 41 detects the calcium and magnesium content in the soil, the data is transmitted to the control end. The control end controls the solenoid valve to open according to the detection data, quantitatively transports the fertilizer in the fertilizer box 9, controls the mixing pump 8 to quantitatively transport the clean water in the water tank 7 to the mixing box 61, and starts the drive motor 64 to mix and dissolve the fertilizer and water, thereby dynamically adjusting the concentration of the liquid fertilizer according to the calcium and magnesium content in the soil. In step S5, after the concentration of the water-soluble fertilizer is adjusted, the electric cylinder 27 is started. The two electric cylinders 27 reciprocate and extend, driving the two gear plates 26 to slide back and forth on the surface of the slide rail 25. The two gear plates 26 move back and forth to drive the two gears 24 to rotate back and forth. The reciprocating rotation of the two gears 24 drives the atomizing nozzle 23 to swing back and forth through the spraying pipe 22, thereby spraying the water-soluble fertilizer on the crops.
