Description

Technical Field

[0001] This utility model belongs to the field of pesticide spraying devices, specifically, it relates to a pesticide spraying device for the control of forest pests and diseases. Background Technology

[0002] Pest and disease control is the artificial means to reduce or prevent the harm of pathogenic microorganisms and pests to crops or livestock. It can generally be divided into chemical control using chemical substances such as insecticides and physical control using physical energy such as light or rays or building barriers.

[0003] Chinese patent CN218245318U discloses a pesticide spraying device for controlling forest pests and diseases. The device uses a motor to start a rotating shaft, which in turn rotates a stirring frame to mix the pesticide solution inside the tank. The rotating arc-shaped cleaning plate can scrape off the pesticide adhering to the inner surface of the tank, and also facilitates cleaning of the inner surface of the tank during subsequent cleaning.

[0004] However, the aforementioned forestry pest and disease control spraying device uses a motor-driven rotating shaft to stir the mixing frame horizontally, resulting in low uniformity of the pesticide solution in the vertical direction. This affects the uniformity of the pesticide concentration and, consequently, the effectiveness of the pesticide.

[0005] In view of this, this utility model is proposed. Utility Model Content

One end of the output shaft of the second servo motor 307 extends into the U-shaped bracket 306 and is fixedly connected to the spray pipe 304. This facilitates the operation of the medicine pump 301 to transport the medicine liquid in the medicine tank 2 through the hose 302 and the rigid pipe 303 to the spray pipe 304, and then spray it out through the spray holes on the spray pipe 304. The operation of the electric push rod 305 drives the U-shaped bracket 306 to move the spray pipe 304 upward, which facilitates the adjustment of the spraying height of the spray pipe 304. The operation of the second servo motor 307 drives the spray pipe 304 to rotate, which facilitates the adjustment of the spraying tilt angle and improves the diversity of spraying.

[0031] Working principle: Medicine and water are discharged into medicine tank 2 through the feed hopper and feed valve 11. Feed valve 11 is closed, and the first servo motor 5 is turned on to drive the transmission shaft 4, which in turn rotates multiple stirring blades 6, filter cylinder 7, and auger blades 8. The auger blades 8 vertically lift the liquid between the filter cylinder 7 and medicine tank 2, allowing the liquid above the height inside the filter cylinder 7 to flow back into the filter cylinder 7 through the filter holes, facilitating vertical circulation and mixing of the liquid. The rotation of the stirring blades 6 facilitates horizontal stirring of medicine tank 2. The internal medicine liquid facilitates the uniformity of mixing of the medicine liquid in the medicine tank 2. The medicine pump 301 is turned on to transport the medicine liquid in the medicine tank 2 through the hose 302 and the rigid pipe 303 to the spray pipe 304, and spray it out through the spray hole on the spray pipe 304. The electric push rod 305 is turned on to drive the U-shaped bracket 306 to move the spray pipe 304 upward, which facilitates the adjustment of the spraying height of the spray pipe 304. The second servo motor 307 is turned on to drive the spray pipe 304 to rotate, which facilitates the adjustment of the spraying tilt angle and improves the diversity of spraying.
