PROBLEM TO BE SOLVED: To provide a herbicide spray vehicle which feeds a herbicide to only a nozzle required for spraying the herbicide and is capable of spraying the herbicide on one or both sides of a curbstone to the minimum.SOLUTION: The herbicide spray vehicle is constituted of: a herbicide tank mounted on a travel vehicle; a pump connected to the tank; a branch joint connected to a discharge pipe of the pump; plural hoses 35 connected to the branch joint; opening/closing valves arranged in the middle of the hoses, respectively; a lifting/lowering mechanism 16 arranged on a front face of a body frame of the travel vehicle; a lifting/lowering plate 17 attached to the lifting/lowering mechanism; horizontal movement mechanisms 18, 19 attached horizontally to a front face of the lifting/lowering plate in upper/lower 2 stages; a rear stage lateral movement frame 20 attached to one horizontal movement mechanism; a first injection nozzle attachment plate attached to the rear stage lateral movement frame; and a front stage lateral movement frame 25 attached to the other horizontal movement mechanism. The herbicide is injected from the injection nozzle through the hose connected to the arbitrary opening and closing valve which has been opened.SELECTED DRAWING: Figure 2 |
