DETAILED DESCRIPTION

[0018] The following will be combined with the accompanying drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clear that the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The utility model provides Figures 1 to 4 The device shown is a drug spraying device for controlling pine wood nematodes, including a frame 1. The frame 1 includes a support plate, a moving wheel and other structures. It can be pushed by an operator, or a driving device can be set to achieve the effect of automatic movement. The driving device includes a driving motor and other structures. The driving device is a common existing technology and will not be described here.

[0020] Considering the high trunks of pine trees and the increased difficulty of spraying pesticides when the trunks become crooked due to factors such as planter errors, to improve spraying efficiency, a guide rod 2 is fixedly connected to the upper surface of the frame 1. A slide 4 is slidably connected to the guide rod 2. The slide 4 slides on the guide rod 2 to facilitate height adjustment. A square groove 5 is defined at the end of the slide 4 away from the guide rod 2. An arc bar 6 is disposed within the square groove 5. A third motor 20 is fixedly connected to the outer wall of the slide 4. The slide 4 also has a circular groove for the drive shaft of the third motor 20 to pass through. The arc bar 6 is fixedly connected to the drive shaft of the third motor 20. The third motor 20 drives the arc bar 6 to rotate, facilitating adjustment of the tilt angle.

[0021] The top of the guide rod 2 is fixedly connected to the cross plate 3, and the bottom end of the cross plate 3 is rotatably connected to the threaded rod 17. The bottom end of the threaded rod 17 is rotatably connected to the vehicle frame 1. The slide 4 has a threaded hole that cooperates with the threaded rod 17. The top of the cross plate 3 is fixedly connected to the second motor 18, and the threaded rod 17 is fixedly connected to the drive shaft of the second motor 18. The second motor 18 drives the threaded rod 17 to rotate. Because the slide 4 has a threaded hole that cooperates with the threaded rod 17, and under the limited cooperation of the guide rod 2, the slide 4 drives the arc bar 6 to move up and down.

[0022] The upper and lower ends of the arc strip 6 are fixedly connected to an arc sleeve 7. An arc box 8 is slidably mounted within the arc sleeve 7. The arc box 8 can be a curved structure, facilitating spraying around the exterior of the tree trunk. A vertical box 13 is positioned between the two arc boxes 8. Two vertical boxes 13 are provided, one corresponding to each end of the arc box 8. Connecting pipes 12 are connected to the upper and lower ends of each vertical box 13. The ends of the connecting pipes 12 facing away from the vertical boxes 13 are connected to the corresponding arc box 8. Multiple nozzles 14 are provided on the sides of the two vertical boxes 13 that are closer to each other. The pest control agent is transported through the arc box 8, connecting pipes 12, and vertical boxes 13, and sprayed toward the tree trunk by the nozzles 14. As the arc box 8 slides within the arc sleeve 7, it drives the vertical boxes 13 and nozzles 14 via the connecting pipes 12, spraying around the exterior of the tree trunk.

[0023] Specifically, the slide 4 slides on the guide rod 2 to facilitate adjustment of the height of the vertical box 13 and the nozzle 14 to meet the spraying needs at different heights of the tree trunk; the third motor 20 drives the arc bar 6 to rotate to adjust the inclination angle of the vertical box 13 and the nozzle 14 to meet the needs of the inclined tree trunk; when the arc box 8 slides inside the arc sleeve 7, it will drive the vertical box 13 and the nozzle 14 to move through the connecting tube 12, and can spray around the outside of the tree trunk to expand the coverage area, thereby improving the practicality of the drug spraying device.

[0024] A rack 9 is fixedly connected to one of the arc boxes 8, and a first motor 11 is fixedly connected to the corresponding arc sleeve 7. A gear 10 is fixedly connected to the drive shaft of the first motor 11, and the gear 10 is meshed with the rack 9. Specifically, the first motor 11 drives the gear 10 to rotate. Since the gear 10 is meshed with the rack 9, the rack 9 drives the arc box 8 to rotate. The arc box 8 drives the vertical box 13 and the nozzle 14 to move through the connecting pipe 12.

[0025] A barrel 16 is fixedly connected to the frame 1. The barrel 16 is filled with preventive and therapeutic drugs. A pump 19 is fixedly connected to the outer wall of the barrel 16. The liquid inlet of the pump 19 is connected to the barrel 16. The liquid outlet of the pump 19 is connected to a liquid pipe 15. The end of the liquid pipe 15 away from the pump 19 is connected to one of the arc boxes 8. The pump 19 sucks the drugs inside the barrel 16 and delivers them to the corresponding arc box 8 through the liquid pipe 15.

[0026] In addition, a stirring device may be provided on the barrel body 16 , and the stirring device includes a stirring blade and other structures, which can stir the medicine inside the barrel body 16 to ensure the uniformity of the medicine.
