The invention discloses a pest-searching
pesticide-injecting device for a
trunk and a use method of the device. The device includes a lifting
system, a scanning
system and an injection
system. The usemethod comprises the following steps: acquiring an original image of a
trunk surface through 360 degree rotating
image acquisition, and sending the acquired original image to a host computer throughWiFi for image recognition; when a fresh
wormhole is recognized, stopping rotation and vertical lifting; realizing precise positioning by using a cross slide table, a
pesticide application push rod and a
laser scanner; realizing rotation pushing of a
pesticide injecting guide head and guide
pipe into the
wormhole through a rotating component and line pushing; and pumping a pesticide liquid from apesticide tank by using a pesticide pump, and injecting the pesticide liquid into the deep place of the
wormhole. Compared with the prior art, the pest-searching pesticide-injecting device for the
trunk and the use method of the device provided by the invention avoid injection of a pesticide into mechanical damage holes and old wormholes, the guide head can enter the deep place of the wormhole todirectly kill pests, injection of the pesticide into the deep place of the wormhole improves the
utilization rate of the pesticide, automatic search and pesticide injection of the wormhole of the treemain trunk are automatically realized, and the shortcomings of bending down in a low place, and out of reach or
sight in a high pace of manual operation in the past are solved.
