Regulating device for air inlets of air-assisted sprayer

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of agricultural plant protection machinery, and in particular relates to an air inlet adjusting device for an air-driven sprayer. Background technique [0002] In recent years, the damage caused by diseases and insect pests of fruit trees has been serious, which has brought huge economic losses to fruit farmers. At present, manual pesticide application is the main pesticide application method used in orchards in my country, but its pesticide utilization rate is low, the environment is seriously polluted, and it is time-consuming and labor-intensive. Since the end of the last century, my country has started research on precision pesticide application technology. Although some achievements have been achieved, there are still common shortcomings such as low pesticide application efficiency and poor target pertinence. Precision pesticide application technology can not only increase yield and reduce the pollutio...
