Description

Technical Field

[0001] The utility model relates to the field of forest medicine dispersing devices, in particular to a safe medicine dispersing device for preventing and controlling forest diseases and insect pests. Background Art

[0002] The prevention and control of tree diseases and insect pests is an important part of forestry production to ensure forest health and ecological balance. Spraying insecticides is a major technical means of preventing and controlling tree diseases and insect pests in forestry production. Ground spraying has been increasingly widely used in artificial breeding and forestry production due to its advantages of low cost and easy control. In order to ensure that the spraying of pesticides can cover the entire production area while also ensuring that each spraying area is evenly covered by the pesticide, special spraying devices are usually used in forestry management to spread the pesticides in a uniform and easy-to-spread form at a certain height in the growth area of the trees. Compared with the traditional manual spraying method, this spraying method has the advantages of a large coverage area, high spreading efficiency, and low waste of pesticides. Therefore, it has received increasing attention and attention. The prior art has disclosed a variety of spraying device technical solutions with different structures, different functions, and different functional implementation methods, which have solved specific technical problems in the field of forest spraying devices. However, due to the generally low functional integration, the spraying devices disclosed in the prior art still need to be improved. The utility model of the authorization announcement number CN221128569U The new patent discloses "a rotating spraying device for preventing and controlling forest pests and diseases". Although this technical solution adopts the technical means of rotating spherical nozzles and wind blowing to achieve uniform coverage of trees and vegetation with pesticides, and improve the spraying range and spraying effect, the spherical nozzle is installed on the front top of the device, and the reaction force of the sprayed pesticide is used to drive the rotation. When the speed is low, the rear nozzle will inevitably scatter the pesticide on the surface of the device. Long-term erosion by the pesticide can easily cause operational failures of the spraying device. More importantly, the spherical nozzle rotates 360° to scatter the pesticide, so the operator cannot avoid the direction of the spraying. The operator is directly facing the spraying of the pesticide throughout the process, which can easily lead to poisoning. The safety hazards are very prominent. Therefore, it is necessary to conduct further research and improvement to solve the problems of the existing technology. Utility Model Content
