[0023] Specifically, the base 14 is provided with buckles or bolts and the like, so as to detachably connect the base 14 with a track vehicle, a tracked vehicle or a wheeled chassis and the like walking mechanism 20, thereby improving the use flexibility of the pesticide spraying mechanism 10. The spraying assembly 12 can suck pesticide liquid in the pesticide tank 13 and spray the pesticide liquid into the air path of the wind delivery assembly 11, and the pesticide liquid is blown by the wind delivery assembly 11, so as to expand the pesticide spraying range and improve the pesticide application efficiency.

[0024] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , in the embodiment of the present application, the pesticide tank 13 and the spraying assembly 12 are in fluid communication through a filter 121, and the filter 121 is detachably connected to the bottom of the wind delivery assembly 11.

[0025] Among them, the pesticide tank 13 and the spraying assembly 12 are communicated through a pipeline, and a filter 121 is arranged in the pipeline, and the filter 121 can filter the particulate impurities in the pesticide liquid, so as to avoid the particulate impurities from blocking the spraying assembly 12. The filter 121 is mounted at the bottom of the wind delivery assembly 11 by means of thread or buckle cooperation, on the one hand, the filter 121 does not occupy the layout space of the pesticide tank 13, so as to ensure that the pesticide tank 13 has a large capacity of pesticide liquid; on the other hand, the filter 121 can be detached below the wind delivery assembly 11, so as to facilitate the cleaning and maintenance of the filter 121.

[0026] Referring to Figure 2 and Figure 3 , the wind delivery assembly 11 comprises a wind cylinder 112 and a fan 113, and the fan 113 is mounted inside the wind cylinder 112, and the filter 121 is mounted at the bottom of the wind cylinder 112.

[0027] The fan 113 is driven by a motor to rotate an impeller coaxial with the air duct 112, so as to realize air supply along the air duct 112. The filter 121 is located at the bottom outside of the air duct 112, which not only facilitates the maintenance of the filter 121, but also avoids occupying the internal air path of the air duct 112.
