[0026] With the above structure, when the height and angle of the spraying plate 34 are adjusted, the spraying plate 34 will cover the outside of the fruit tree plant. At this time, the rotary spraying motor 321 and the liquid extraction pump 51 are turned on. First, after the rotary spraying motor 321 operates, due to the meshing transmission of the rotary spraying gear 322 and the rotating gear 331, the spraying plate 34 will rotate around the fruit tree plant. Second, after the liquid extraction pump 51 is turned on, the medicine in the medicine box 2 will be extracted and conveyed into the spraying plate 34, and finally sprayed onto the fruit tree plant by a plurality of spraying nozzles 341, so as to realize the comprehensive spraying of the fruit tree plant, ensure the uniformity of the medicine coverage, avoid the phenomenon of too high or too low local medicine concentration, improve the effectiveness of the pesticide, and achieve the best pest control effect.

[0029] Refer to Figure 1 , Figure 3 , Figure 5 andFigure 6 Among them, the pressurization assembly includes two pressurization boxes 7, which are respectively fixed on both sides of the medicine box 2, and both ends of the liquid stirring shaft 4 penetrate to the center of the inner cavities of the two pressurization boxes 7. Both sides of the pressurization box 7 are fixedly connected and communicated with piston chambers 71. A piston plate 72 is slidably connected in the piston chamber 71. A return spring 73 is fixedly connected between the side wall of the piston plate 72 and the inner wall of the piston chamber 71. A magnetic plate 74 is fixedly connected to the outer wall of the liquid stirring shaft 4 located in the pressurization box 7, and the magnetic plate 74 and the piston plate 72 repel each other magnetically.

[0030] It should be noted that the check valve in the pressurization pipe 77 can only allow the gas in the piston chamber 71 to enter the medicine box 2; the check valve in the air inlet pipe 79 can only allow the outside air flow to be supplemented into the piston chamber 71.

[0031] Through the setting of the above structure, when the liquid stirring shaft 4 rotates, it will drive the magnetic plate 74 to rotate in the pressurization box 7. At this time, using the magnetic repulsion between the magnetic plate 74 and the piston plate 72, when the two are in the repulsion area, it will push the piston plate 72 to slide towards the side that compresses the return spring 73, thereby compressing the gas in the piston chamber 71 and pushing open the check valve in the pressurization pipe 77, so that the compressed gas is filled into the medicine box 2 along the gas guide pipe 75, the multi-pass ball 76 and the pressurization pipe 77, thereby increasing the air pressure in the medicine box 2, pushing the medicine towards the input port of the liquid extraction pipe 5, overcoming a part of the frictional loss and other resistances generated in the pipeline, so that the medicine can be pumped out more quickly, and thus improving the spraying speed of the medicine; When the magnetic plate 74 and the piston plate 72 are out of the repulsion area, under the rebounding action of the return spring 73, the piston plate 72 will slide back to its original position, thereby generating a negative pressure suction force in the piston chamber 71, so that the check valve in the air inlet pipe 79 is opened, and the outside air flow is supplemented into the piston chamber 71 after passing through the filter box 791, so as to continuously pressurize the medicine box 2.

[0032] Embodiment Two: Refer to Figures 1-6 , which is basically the same as Embodiment One. On the basis of Embodiment One, a whole-plant spraying method for plants is proposed, including the following steps: Step One: Adjust the height and angle of the spraying plate 34 and wrap it around the outside of the fruit tree plant; Step 2: Rotate the spraying plate 34, and spray the medicament in the medicine box 2 along the spraying head 341 onto the fruit tree plants, completing the full spraying of the entire fruit tree; Step 3: While Step 2 is in progress, mix and stir the medicament in the medicine box 2; Step 4: While Step 2 is in progress, fill the medicine box 2 with gas for pressurization.

[0033] Refer to Figures 1-6 , in the present invention, when in use, first turn on the lifting motor 352 to drive the lifting lead screw 351 to rotate, so that the lifting sleeve 353 slides along the lifting lead screw 351, and cooperates with the lifting rod 354 to drive the lifting column 31 to lift, thereby adjusting the spraying height of the spraying plate 34; then turn on the steering gear 8, and through the meshing transmission of the driving gear 82 and the steering gear 8, drive the whole column sleeve 3 to rotate, thereby adjusting the spraying angle of the spraying plate 34; thus realizing the adjustment of the height and angle of the spraying plate 34, which can adapt to fruit tree plants of different heights and positions, and improves the convenience of spraying.

[0034] After the height and angle of the spraying plate 34 are adjusted, the spraying plate 34 will cover the outside of the fruit tree plants. At this time, turn on the rotary spraying motor 321 and the liquid extraction pump 51. First, after the rotary spraying motor 321 operates, due to the meshing transmission of the rotary spraying gear 322 and the rotating gear 331, the spraying plate 34 will rotate around the fruit tree plants. Secondly, after the liquid extraction pump 51 is turned on, it will extract the medicament in the medicine box 2 and transport it to the spraying plate 34. Finally, it will be sprayed onto the fruit tree plants by multiple groups of spraying heads 341, thereby realizing the full spraying of the fruit tree plants, ensuring the uniformity of the medicament coverage, avoiding the phenomenon of too high or too low local medicament concentration, improving the effectiveness of the pesticide, and thus achieving the best pest control effect.

[0035] In addition, during the process of the liquid extraction pump 51 extracting the medicament, the medicament in the medicine box 2 will flow along the liquid extraction pipe 5 and into the driving box 6, thereby using the thrust generated by the flow of the medicament liquid to drive the rotation of the hydraulic impeller 61, so that the stirring shaft 4 drives the stirring impeller 62 to rotate in the medicine box 2, thereby stirring the medicament in the medicine box 2 and uniformly mixing the components therein, effectively improving the use effect of the medicament; at the same time, when the stirring shaft 4 rotates, it will drive the magnetic plate 74 to rotate in the pressurizing box 7. At this time, using the magnetic repulsion between the magnetic plate 74 and the piston plate 72, when the two are in the repulsion region, it will push the piston plate 72 to slide towards the side of the compression return spring 73, thereby compressing the gas in the piston chamber 71 and pushing open the one-way valve in the pressurizing pipe 77, so that the compressed gas is filled into the medicine box 2 along the air guide pipe 75, the multi-pass ball 76 and the pressurizing pipe 77, thereby increasing the air pressure in the medicine box 2, and pushing the medicament towards the input port of the liquid extraction pipe 5 to overcome a part of the frictional loss and other resistances generated in the pipeline, so that the medicament can be extracted more quickly, and thus the spraying speed of the medicament is improved.
