The invention discloses a regulating device for air inlets of an air-assisted
sprayer. The regulating device for the air inlets of the air-assisted
sprayer comprises a left guide air bellow and a right guide air bellow, wherein the left guide air bellow and the right guide air bellow are fixedly arranged on a
chassis of the
sprayer. Sprayers and a
centrifugal fan are respectively arranged in the air
bellows, wherein the sprayers are communicated with a
pesticide tank, and the
wind direction of the
centrifugal fan faces the sprayers; the air inlet of each air bellow is provided with a conical air inlet device; each air inlet device is fixedly provided with a round baffle which is coaxial with the air inlet device, can rotate along the axis and is provided a plurality of
scallop holes; and the baffles are respectively controlled by a stepping motor to rotate to realize the change of the
air volume of the air inlet of the corresponding air bellow. According to the regulating device for the air inlets of the air-assisted sprayer, the stepping motors are controlled through regulating a manual controller to drive the baffle to move, and therefore, the area of the air inlet of the corresponding guide air bellow is regulated, the change of the air input of the garden air-assisted sprayer is realized, and further, the change of the
air volume is realized so as to meet the requirements of different fruiter crown sizes and distances on precision application, the
pollution of chemical pesticides to the environment is reduced, and the application level is improved. The regulating device is sensitive in reaction and precise in control.
