a spray device

Abstract

The invention discloses a spraying device, which comprises a walking mechanism and a spraying part, wherein the spraying part comprises a support frame, a spray pipe, a box body, a piston, a first rotating sheet, a second rotating sheet, a third rotating sheet, a fourth rotating sheet, a rotating wheel, a connecting rod, a power unit, an air outlet pipe, a medicine storage box and a three-cylinder plunger piston pump; the support frame is arranged on the walking mechanism; the suction pipe is arranged on the support frame; the spray pipe is arranged along the walking path of the walking mechanism; the box body is arranged on the walking mechanism; an air inlet hole, a first connecting hole, a second connecting hole, a third connecting hole, a fourth connecting hole and an air outlet hole are formed in the box body; an installing hole is formed in the top wall of the box body; a first accommodating cavity, a second accommodating cavity and a third accommodating cavity are sequentially arranged in the box body; the piston is arranged in the second accommodating cavity; the air inlet hole, the first connecting hole and the second connecting hole are connected with the first accommodating cavity.

Description

technical field [0001] The invention relates to a spray device. Background technique [0002] Due to the relatively low degree of automation of plant protection machinery in my country, for the prevention and control of crops such as corn and wheat, most of them rely on manual mechanical or electric sprayers to spray field crops. In the environment of fog droplet drift and high temperature operation, it is easy to cause poisoning and heatstroke of workers, resulting in unnecessary casualties. [0003] At present, there are many crop plant protection machines on the market for the prevention and control of crop diseases and insect pests. There are also problems such as short spray range and limited coverage area, which cannot effectively prevent and control crop diseases and insect pests. Contents of the invention [0004] In order to solve the technical problems in the background technology, the present invention proposes a spray device with good effect. [0005] A sprayi...
