Air volume regulating device of air assisted sprayer

Abstract

The invention discloses an air volume regulating device of an air assisted sprayer, comprising a sprayer underpan arranged on a tractor; a pesticide box is located on the sprayer underpan; a left guide air box and a right guide air box which are symmetric are arranged on the sprayer underpan and at the rear of the pesticide box; the left guide air box is internally provided with a group of spray heads and a centrifugal fan; two sides of the left guide air box are respectively provided with a left guide slot I and a left guide slot II; the left guide slot I is internally provided with a left moving baffle I; the left guide slot II is internally provided with a left moving baffle II; the upper ends and the lower ends of the left moving baffle I and the left moving baffle II are provided with pulleys; the left moving baffle I is provided with a left rack I; the left moving baffle II is provided with a left rack II; a gear connected with a stepping motor and meshed with the left rack I and the left rack II is arranged between the left rack I and the left rack II; the stepping motor is arranged on a manual controller on the tractor; and the left guide air box and the right guide air box are consistent in structure. By using the air volume regulating device, the air volume can be changed through regulating the manual control in real time according to the actual requirement so that pesticide is precisely sprayed.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to an air volume regulating device for an air-driven sprayer. Background technique [0002] Pest control is an essential link in the fruit planting process. It is labor-intensive, time-consuming, and labor-intensive. Its workload accounts for about 30% of the total workload of fruit tree management. At present, the pesticide application machinery used in my country's orchards is still dominated by manual pesticide machinery, and the main varieties are manual sprayers and pedal sprayers. Since the 1980s, my country has successively introduced and developed a number of orchard air-driven sprayers, but there are generally shortcomings such as poor target pertinence and small working scope. Precision pesticide application in orchards is a hot topic in the research of modern orchard pesticide application technology at home and abroad. It not only maximizes the...
