Self-propelled dual-rod lifting multi-angle spraying pesticide sprayer

Abstract

The invention discloses a self-propelled dual-rod lifting multi-angle spraying pesticide sprayer, and relates to the field of agricultural devices. The sprayer comprises a three-wheel walking car, a spraying rod assembly, a spraying rod angle adjusting structure, a PLC control cabinet and a liquid medicine tank; the spraying rod assembly comprises two bearing pedestals arranged on the upper surface of the three-wheel walking car in parallel, the two bearing pedestals are each internally and rotationally connected with a supporting rod structure, one end of a supporting rod body is fixedly connected with a second connecting column, and a first electric hydraulic rod is perpendicularly arranged at the top face of the second connecting column. The spraying rod assembly is hinged to a third hinge structure and a fourth hinge structure through a rotating arm for rotating angle regulation, the spraying rod assembly is regulated to ascend and descend through lifting of the first electric hydraulic rod, the length of a transverse supporting arm is regulated through lifting of a second electric hydraulic rod, the corn planting requirement for different corn planting lands and different growth conditions can be met, operation is good, the spraying working efficiency is high, the coverage is wide, and the automatic level is high.

Description

technical field [0001] The invention belongs to the field of agricultural equipment, in particular to a self-propelled double-rod lifting multi-angle spraying machine. Background technique [0002] Crops such as corn will be harmed by diseases, insects, rats, etc. to varying degrees during the growth process. In order to prevent or reduce losses of crops, chemical pesticides are usually used to treat crops, insects, grasses, rats, etc. prevention. Among them, the most commonly used method of using chemical pesticides is the spray method, which is to spray the crops with spray rods and nozzles. [0003] For different growing places and different periods of corn, the growth conditions and height densities of different varieties of corn are different. The spray arm of the traditional sprayer sprayer is a whole root arm, so the application number is CN201010248467.X The Chinese invention patent proposes a boom-type sprayer, but it can only spray crops on one surface at the sam...

Problems solved by technology

[0004] The purpose of the present invention is to provide a self-propelled double-rod lifting multi-angle spraying machine, by adjusting the rotation angle of the spray rod assembly through the pivoting arm and the third hinge structure and the fourth hinge structure, the first electro-hydraulic rod Lift and adjust the lifting of the spray rod assembly, lift the second electro-hydraulic rod, adjust the length of the horizontal support arm, the bottom of the horizontal support arm is hinged with a limit adjustment structure, the horizontal support arm is folded, and the L-shaped connecting block is rotated and connected There is a second spray pipe fixing plate that slides and fits with the first "concave" connecting ring on the base of the first electro-hydraulic rod, and the connecting block is rotatably connected with the first spray pipe that slides and fits with the second "concave" connecting ring The fixed plate, the first spray pipe fixed plate and the second spray pipe fixed plate are provided with a spray nozzle connected with the infusion pipe extending from the liquid medicine tank provided on the upper surface of the tricycle, and the spray nozzle and the infusion pipe are fixed along with the spray pipe. The expansion and contraction of the plate solves the problems that the existing drug spraying machine cannot meet the requirements of different corn planting places and different growth conditions, poor operation, low spraying efficiency, small coverage, and low automation level.
