Electric-pressurization pesticide spraying device

Abstract

The invention provides an electric-pressurization pesticide spraying device. The pesticide spraying device comprises a water tank, a spraying mechanism and a pressurizing mechanism, and the pesticidespraying mechanism is connected with the water tank through a pesticide conveying pipe; the key points are that the pressurizing mechanism comprises an electric air pump and a battery connected with the electric air pump, an air inlet of the electric air pump is exposed out of the water tank, and an air outlet is located in the water tank; a switch of the electric air pump is formed by connectinga first switch and a second switch in series, wherein the second switch is a pressure switch for detecting gas pressure in the water tank, the second switch is disconnected when the gas pressure in the water tank exceeds a first preset pressure, and the second switch is connected when the gas pressure in the water tank is lower than a second preset pressure. The electric-pressurization pesticide spraying device is simple in structure, the electric air pump can be used for pressurizing the water tank, and labor intensity of operators is reduced. Meanwhile, through the design of the double switches, the potential safety hazard that the internal pressure of the water tank is too high is avoided, and good practicability is achieved.

Description

technical field [0001] The invention belongs to the technical field of agricultural equipment, and in particular relates to a pesticide spraying device. Background technique [0002] In order to improve the disease resistance of crops, it is often necessary to spray pesticides on crops. The traditional pesticide spraying device is composed of a water tank, a manual pressurization mechanism and a hand-held nozzle. During the process of spraying pesticides, the operator must continue to press the manual pressurization mechanism to maintain a predetermined pressure in the water tank, which greatly increases the labor burden on the operator. Contents of the invention [0003] The object of the present invention is to propose a labor-saving and conveniently controlled electric pressurized pesticide spraying device. [0004] The electric pressurized pesticide spraying device of the present invention comprises a water tank, a spraying mechanism and a pressurizing mechanism, and ...
