Air-assisted variable-rate spraying machine

Abstract

The invention relates to a plant protection machine in the field of agricultural and forestry machines, and provides an air-assisted variable-rate spraying machine. The air-assisted variable-rate spraying machine is mainly used for conducting variable-spraying when a pesticide is applied to fruit trees according to the characteristics of the fruit trees. The air-assisted variable-rate spraying machine at least comprises a variable-rate spraying execution module which is composed of an air-assisted system on the rear portion of a rack and a variable-rate spraying system. The air-assisted system comprises an engine in the rack, a centrifugal fan on the rear portion of the rack, a multi-outlet pipeline air-assisted device and air-assisted pipes, wherein the multi-outlet pipeline air-assisted device is communicated with an outlet of the centrifugal fan, the air-assisted pipes are communicated with the multi-outlet pipeline air-assisted device through soft air pipes and provided with a plurality of air-assisted openings. The variable-rate spraying system comprises a pesticide box in the rack, a piston pump driven by the engine, a distributor and sprayers, wherein the distributor is arranged on the rack, communicated with the piston pump through a soft pesticide liquid pipe and provided with a plurality of distribution pipes, the sprayers are arranged in the air-assisted openings respectively, communicated with the distribution pipes through the soft pesticide liquid pipe and electromagnetic valves, and the electromagnetic valves are electrically connected with a single-chip microcontroller.

Description

technical field [0001] The technology relates to plant protection machinery in the field of agricultural and forestry machinery, and provides an air-driven variable sprayer, which is mainly used for variable spraying when spraying fruit trees based on the characteristics of fruit trees. Background technique [0002] In the orchard production links of the prior art, chemical control is still the most effective control measure for plant diseases and insect pests. The orchard pesticide applicator that generally adopts both at home and abroad is an air-driven sprayer. The air-driven sprayer relies on the auxiliary airflow to deliver the fine mist to the target. Although the disturbance between the leaves is increased to a certain extent, the penetration ability of the mist and the coverage of the liquid medicine are improved, and the spray effect is improved. , but these spraying devices still use constant spraying, often through the excessive application of fruit trees to obta...

AI Technical Summary

Problems solved by technology

When the manned sprayer is performing pesticide application in the forest, the spraying environment will cause a certain degree of health threat to the workers and increase the labor cost; due to the limitation of the remote control distance, the remote control self-propelled During drug operations, someone must hold the remote control for tracking operations

[0005] In the actual spraying process of existing orchard sprayers, due to the influence of unknown complex terrain, it often causes vehicle bumps and non-linear driving, etc., and laser sensor detection is prone to deviation, which affects the spraying effect
