Abstract

The invention relates to a spray boom conversion device for a boom sprayer. The device comprises a base, a lifting mechanism and a folding mechanism, wherein the base, an upper frame, a lower frame and a front frame are hinged to form a parallelogram mechanism, and two ends of a lifting actuation piece are hinged to the lower frame and the front frame; a side frame of the folding mechanism is hinged to one side of the front frame, and two ends of a folding actuation piece are hinged to the rear side of the front frame and the rear side of the side support; and a connecting lever of an angular transformation mechanism is connected with the side support, a first fixed support and a second fixed support are fixed on the connecting lever, a first angle actuation piece is hinged to the first fixed support and an intermediate side lever, a second angle actuation piece is hinged to the second fixed support and an oscillating bar, two ends of the oscillating bar are hinged to the connecting lever and a connecting rod, and the connecting rod is hinged to an end side lever. The device has a reasonable structure, can be conveniently and quickly operated, can perform profile modeling spray operation according to target plants, and can meet the control operation requirements of plant diseases and insect pests on different occasions such as field crops, espalier crops, fruit trees and forest.

Description

technical field [0001] The invention relates to a spray rod conversion device for a spray rod sprayer, which belongs to the technical field of plant protection machinery. Background technique [0002] The boom sprayer is mainly composed of a medicine box, a pressure pump, a spray boom and a nozzle pipe connected to the spray boom. The liquid medicine in the medicine box is sprayed to the crops through the pressure pump, nozzle pipe and nozzle for pest control. The boom sprayer is mainly used for the prevention and control of diseases and insect pests of field crops such as rice and wheat. Fruit trees such as pears have orchard-specific tunnel sprayers for pesticide application; it is also disclosed that different spraying sprays can be formed by adjusting the angle between the spray bar and the side spray bar and the relative position of the vertical spray bar and the side spray bar. The shape is not only capable of tunnel spraying, but also suitable for pest control of tre...

AI Technical Summary

Problems solved by technology

However, the currently disclosed boom transformation structure cannot be profiled according to the shape of the boom, so it cannot be applied to crops of various heights and shapes, as well as orchards and street trees.

Furthermore, some currently disclosed spray boom changers are manually operated when the tunnel structure and the "one" shape structure are changed, which is inconvenient to operate.
