Spraying rod conversion device of automatic forest tree profiling spraying machine frame

Abstract

The invention relates to a spraying rod conversion device of a forest tree profiling spraying machine. The spraying rod conversion device comprises two profiling mechanisms, a left rotating execution piece, a left rotating arm, two extending frames, two telescopic execution pieces, an upper frame, a lower frame, two vertical lifting execution pieces, a lifting execution piece, an upper lifting support, a lower lifting support, a rear stand column, a base, two double-shaft steering engines, a right rotating arm and a right rotating execution piece; the whole device has the characteristics of light weight, easiness in manufacturing and maintenance and the like. According to the spraying rod conversion device, two rows of crops on the two sides of a carrier can be operated at the same time, or 360-degree circumferential three-dimensional operation can be performed on the two crops at the same time, so that the spraying leakage phenomenon is avoided. The spraying rod conversion device has multiple purposes, is wide in application range, can realize profiling spraying operation according to target plants, can meet pest control operation requirements of field crops, trellis crops, fruit trees, forest trees and other different occasions.

Description

technical field [0001] The invention relates to a plant protection machine, in particular to a spray rod changing device for an automatic profiling spray frame for trees. Background technique [0002] In recent years, my country's forestry industry has developed rapidly, and the planting area and production volume of various forest trees have increased year by year, such as fruit trees, street trees, landscape trees and other forest trees. In order to deal with the problems of tree diseases and insect pests, sampling and precise spraying technology is used to apply pesticides to trees, which can not only prevent and control plant diseases and insect pests, but also reduce pesticide residues and environmental pollution. [0003] At present, there are three mainstream spraying methods for sprayers. The one-shaped boom sprayer is mainly used for the prevention and control of plant diseases and insect pests in field crops such as rice, wheat and corn; The profile sprayer is mai...
