Multifunctional agricultural spraying machine

Abstract

The invention discloses a multifunctional agricultural spraying machine. The machine comprises a box body, a pressure spraying device, a walking mechanism, a connecting mechanism, a telescopic supporting frame and an annular nozzle, the pressure spraying device is installed at the inner end of the box body, the walking mechanism is fixedly installed at the bottom of the box body, the connecting mechanism is fixedly installed on one side of the outer end of the box body, the telescopic supporting frame is connected with the box body through the connecting mechanism, and the annular nozzle is fixedly installed at the front end of the telescopic supporting frame. According to the spraying machine, by adopting the special structure of the annular nozzle, the annular nozzle sleeves the outer surface of a tree trunk, 360-degree all-direction spraying is conducted on the tree trunk, and therefore the uniformity of pesticide spraying is ensured. By adopting a lead screw and a driving motor, the up-and-down controlling over the annular nozzle is achieved, the automatic operation of the annular nozzle is achieved, the convenience of operation is greatly improved, and labor force is saved.

Description

technical field [0001] The invention relates to the field of sprayers, in particular to a multifunctional agricultural sprayer. Background technique [0002] At present, the spraying of pesticides on trees is mostly carried out by using the chemical pump to supply the spray gun with high-pressure liquid spraying through the rubber hose. If the spray gun produces a large amount of liquid per unit time, it will easily cause insufficient hydraulic pressure and fail to achieve the ideal range and spray effect. Therefore, it is not possible to use large spray holes or multiple Orifice spray gun. In tree spraying, one or two spray guns are usually supplied by the medicine pump to spray the trees continuously. This continuous spraying method for trees is prone to partial re-spraying and blind spraying when pulling the rubber hose, especially when carrying out tree trunk spraying. When fully spraying, the applicators need to operate around the trunk, which is time-consuming and lab...
