The invention discloses an automatic
pesticide spraying device which comprises a movable vehicle body and a
pesticide spraying box arranged on the top of the left side of the movable vehicle body; a
pesticide storage cavity is formed inside the pesticide spraying box, a stirring mechanism is in rotating-fit connection with the interior of the pesticide storage cavity, a first transmission cavity is formed in the portion, at the bottom of the pesticide spraying box, of the movable vehicle body, a second transmission cavity extending towards the front side is formed in the portion, on the rightside of the first transmission cavity, of the movable vehicle body, a guiding groove with the top communicated with the end face of the top of the movable vehicle body is formed in the portion, on theright side of the front extending section of the second transmission cavity, of the movable vehicle body, a first rotating shaft extending to the left and right sides is in rotating-fit connection with the portion, between the first transmission cavity and the second transmission cavity, inside the movable vehicle body, the left side end of the first rotating shaft stretches into the first transmission cavity, the
tail end of the first rotating shaft is fixedly provided with a first
bevel gear, the extending section on the right side of the first rotating shaft stretches into the first transmission cavity, and the
tail end of the first rotating shaft is fixedly provided with a second
bevel gear. The device is simple in structure, uniform spraying work for crops of different
plant heightscan be met, the spraying effect is improved, and automatic stirring work can be achieved.
