Hand-pushed air-assisted sprayer

Abstract

The invention relates to the technical field of agricultural machinery, and in particular to a hand-pushed air-assisted sprayer. The hand-pushed air-assisted sprayer includes a frame, wheels, a medical kit, an adjustment rack, an axial flow fan and a nozzle assembly; the frame is formed by bending a metal pipe, and the portions which extend to the front constitute hand-pushed rods; a low-voltage electric diaphragm pump powered by batteries is arranged on the frame and acts as a liquid transport pressure source of the nozzle assembly; the adjustment rack includes a horizontal rotation adjustment rack in the lower part or upper part thereof and a vertical rotation adjustment rack in the upper part or lower part thereof; the working direction of the axial flow fan in the horizontal direction can be adjusted by adjusting the horizontal rotation adjustment rack; the working angle of the axial flow fan in the vertical direction can be adjusted by adjusting the vertical rotation adjustment rack, so that the spraying coverage of the nozzle assembly can be expanded and the sprayer is very applicable to spraying pesticides to tea plantations. The batteries are used to replace a traditional diesel engine and serve as the power source, so that the hand-pushed air-assisted sprayer saves energy and is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a hand-push air sprayer. Background technique [0002] In the prevention and control of plant diseases and insect pests in tea gardens, the tea leaves are densely packed, and the air-supply sprayer is the best machine tool. However, in my country, the air-supply sprayer is mainly driven by tractors, and tea gardens are generally located in hilly forests and mountains. The tractor-driven air-supply sprayer is difficult Enter. Gasoline-driven foggers are also air-driven sprayers, which are backpack-type, labor-intensive, and gasoline pollutes the tea leaves; drinking polluted tea leaves can cause diseases and endanger human health. [0003] Chinese patent application No. 201310256939.X proposes a tall plant spraying agricultural machine, which can adjust the height of the spray bar in the vertical direction, but can not realize stepless adjustment in the vertical dir...

[0003] Chinese patent application No. 201310256939.X proposes a tall plant spraying agricultural machine, which can adjust the height of the spray bar in the vertical direction, but can not realize stepless adjustment in the vertical direction, and can not be adjusted in the horizontal direction. In the working direction, the spray coverage area is small; the traditional air-driven sprayer is relatively heavy and cannot be operated by hand, which is inconvenient to operate
