Description

Technical Field

[0001] The utility model relates to the technical field of agricultural plant protection robots, in particular to an automatic agricultural spraying and pesticide spraying plant protection robot. Background Art

[0002] When spraying pesticides on crops, farmers first pour the pesticides into the medicine box, then add water, and then shake the medicine box several times to fully dilute the pesticides with water. Farmers carry the medicine box on their backs, walk in the fields, and continuously press the piston of the medicine box to spray out the pesticides in the medicine box. Existing automatic agricultural spraying and plant protection robots require manual driving and control of the operation vehicle. When the operator drives the operation vehicle, the sprayed pesticides are easily contaminated on the surface of the operator's clothes, which not only easily pollutes the clothes, but also has high labor intensity. At the same time, when the operation time is long, the operator inhales a large amount of pesticides on the surface of his clothes, which has certain harm to his health. Existing automatic agricultural spraying and plant protection robots require farmers to first pour the pesticides into the medicine box, then add water, and then shake the medicine box several times to fully dilute the pesticides with water. This method is time-consuming and labor-intensive.

[0003] The patent document with announcement number: CN217958048U discloses "an agricultural automatic spraying plant protection robot" involving a medicine box fixedly connected to the top of the bottom plate, a motor fixedly connected to the top of the medicine box, a stirring rod movably connected to the output end of the motor, stirring rods fixedly connected to both sides of the stirring rod, a dosing port fixedly connected to the top of the medicine box, a mouth plug movably connected in the dosing port, the mouth plug is taken out from the dosing port, and then pesticide and water are poured into the medicine box through the dosing port. When the pesticide and water are poured, the mouth plug is inserted into the dosing port, the motor is started, the motor drives the stirring rod to rotate, the stirring rod drives the stirring rod to rotate, the rotating stirring rod fully mixes the pesticide and water in the medicine box to dilute the pesticide, so that the water can automatically dilute the pesticide.

[0004] Although the device drives the stirring rod to rotate through the motor, and the stirring rod drives the stirring rod to rotate, the rotating stirring rod fully mixes the pesticide and water in the medicine box to dilute the pesticide, so that the water can be automatically used to fully dilute the pesticide, but the device is not convenient for cleaning the inner wall of the medicine box. After the medicine box is used, there will be drug residues on the inner wall. When used later, it may be mixed with different drugs, which is not conducive to ensuring the effect of the application.

After use, the inner wall of the medicine box 10 is cleaned. When cleaning, a water supply pipe can be connected to the external pipe 903, and the water in the water supply pipe enters the annular pipe 901 through the external pipe 903, and then is sprayed out through the cleaning nozzle 902 at the bottom of the annular pipe 901 to wash the inner wall of the medicine box 10. At the same time, the second motor 801 drives the stirring rod 802 to rotate again, thereby driving the connecting plate 804 to rotate. When the connecting plate 804 rotates, it can drive the I-shaped block 805 to move. When the I-shaped block 805 moves, it drives the cleaning brush 806 to scrub the inner wall of the medicine box 10. The cleaning brush 806 is used in conjunction with the cleaning nozzle 902 to clean the inner wall of the medicine box 10, which can effectively reduce the drug residue in the medicine box 10, thereby avoiding affecting subsequent use and preventing the mixing of drugs with different functions, which is beneficial to ensuring the effect of drug application. The sewage generated by cleaning can be discharged through the drain valve at the bottom of the medicine box 10. When the cleaning brush 806 is worn out due to long-term use, in order not to affect the cleaning effect, the fixing nut 604 can be twisted off from the outside of the fixing rod 602 to release the first fixing block 601 and the second fixing block 602. The fixed relationship between the fixed blocks 603 is then separated, and the inspection cover 7 is separated from the medicine box 10, so that the connecting plate 804 and other components are moved out of the medicine box 10, and then the limit bolt 808 is twisted out from the threaded groove at the top of the connecting plate 804 to release the fixation of the limit plate 807. After removing the limit plate 807, the I-block 805 is pulled out from the top of the connecting plate 804, and the cleaning brush 806 can be replaced. By setting the stabilizing block 13 and the stabilizing groove 14, the limiting effect of the limit plate 807 on the I-block 805 is improved.

[0033] The working principle of the automatic agricultural spraying and pesticide spraying robot provided by the utility model is as follows:

[0034] When using the device, water and pesticide can be added into the medicine box 10 in turn through the injection port on the top of the inspection cover 7, and then the second motor 801 drives the stirring rod 802 to rotate, and the stirring rod 802 rotates to drive the connecting rod 803 and the connecting plate 804 to rotate, so that the pesticide and water are evenly mixed, and there is no need for the user to stir and mix manually, and then the first motor 301 drives the active sprocket 302 to rotate, and the active sprocket 302 rotates to drive the driven sprocket 304 to rotate through the chain 303, and the driven sprocket 304 rotates to drive the rotating rod 305 to rotate, and the rotating rod 305 drives the driving wheel 306 to rotate, thereby driving the crawler 2 to move the device. While moving, the water pump 11 transports the pesticide in the medicine box 10 to the delivery pipe 502, and then sprays it out through the spray head 503 to spray the pesticide on the crops, without the need for the user to spray manually, thereby reducing the labor intensity of the user. After use, when cleaning the inner wall of the medicine box 10, a water supply pipe can be connected to the external pipe 903. The water in the water supply pipe enters the annular pipe 901 through the external pipe 903, and then is sprayed out through the cleaning nozzle 902 at the bottom of the annular pipe 901 to rinse the inner wall of the medicine box 10. At the same time, the second motor 801 drives the stirring rod 802 to rotate again, thereby driving the connecting plate 804 to rotate. When the connecting plate 804 rotates, it can drive the I-shaped block 805 to move. When the I-shaped block 805 moves, it drives the cleaning brush 806 to scrub the inner wall of the medicine box 10. The cleaning brush 806 is used in conjunction with the cleaning nozzle 902 to clean the inner wall of the medicine box 10, which can effectively reduce the drug residue in the medicine box 10, thereby avoiding affecting subsequent use and preventing the mixing of drugs with different functions, which is beneficial to ensuring the application effect. The sewage generated by cleaning can be discharged through the drain valve at the bottom of the medicine box 10.
