Description

Technical Field

[0001] This utility model relates to the field of forestry tree protection technology, specifically to a forestry tree protection spraying device. Background Technology

[0002] Forestry refers to the production sector that protects the ecological environment and maintains ecological balance, cultivates and protects forests to obtain timber and other forest products, and utilizes the natural characteristics of trees for protective purposes. It is an important component of the national economy. In the human and biosphere, forestry, through advanced science and technology and management methods, cultivates, protects, and utilizes forest resources to fully realize the multiple benefits of forests. To protect trees, they are usually sprayed with insect-repellent coatings. A search revealed existing technology (Publication No.: CN202321538628.8) for a tree protective spraying device. The document describes that "this utility model, through the design of branch hoses connected to the inside of the conveying trough, allows the coating to be drawn from the back-type coating tank and transferred to the conveying trough during spraying. Finally, it is sprayed out through fan-shaped nozzles, so that the spray from the two fan-shaped nozzles forms a circle, allowing for one-time coverage of the tree without requiring workers to move around too much to slowly spray the trees, thus achieving..." The design effectively improves the efficiency of tree spraying. Both sets of stabilizing blocks have drive ropes fixedly installed on one side. When spraying thicker trees, the drive motor can be started. The drive motor drives two sets of gears to rotate two sets of winding wheels simultaneously. The winding wheels then drive the drive ropes to wind up, which in turn pulls the stabilizing blocks, causing the two measuring annular shells to rotate away from each other. This allows for adjustment of the spraying area with different internal circumferences. Only slight adjustments are needed to spray thicker trees, thus achieving the effect of spraying trees of different thicknesses and improving the practicality of the tree protection spraying equipment. However, in existing technology, the fan-shaped nozzles directly spray the protective liquid, causing splashing and wasting some of the protective liquid. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, a forestry tree protection spraying device is provided to solve the problem of splashing and waste of protective liquid when the protective liquid is directly sprayed by the fan-shaped nozzle in the existing technology.

[0004] To achieve the above objectives, a forestry tree protection spraying device is provided, comprising: a spraying plate, wherein a fan-shaped pressure nozzle is installed on the arc surface of the right end of the spraying plate.
