The invention discloses a plastic
housing type pesticide spraying
machine for trees. The plastic
housing type pesticide spraying
machine for trees is composed of a plastic housing, an annular bracket, a stay cord, a bracket, a spray head, a support plate, a spray head deploying and retracting connecting rod, a transverse bracket, a spray insecticide tank, a
shovel type lifting fork, a spray switch, a longitudinal bracket, a lead rail, a spray head deploying and retracting stay cord, a spraying stay cord, a lifting slide block, a balancing clip, a lifting
rope, a roll wheel, a wheel disc and a motor, and the plastic housing is used for covering the tree to be sprayed so as to enable leaf surfaces of the tree in the housing to uniformly absorb the sprayed
pesticide. When using, the
shovel type lifting fork is shoveled into the support plate, the annular bracket balancing clip is connected with the slide block, the motor is started to pull the plastic housing to the highest point, the pesticide spraying
machine is pushed to the position in front of the tree to place the plastic housing at the center of the top of the tree, the plastic housing is put down, after the tree is basically covered, the spray head stay cord is pulled to deploy and retract, the spray head is placed in from the round hole of the bracket, and then the spraying stay cord is pulled, after the spraying is stable, the plastic housing is pulled towards the upside to perform the pesticide spraying for the next tree.
