Spraying-height-adjustable pesticide mixing and spraying device

Abstract

The invention discloses a spraying-height-adjustable pesticide mixing and spraying device. The device comprises a base, and a mixing box is arranged on the base; a left support plate and a right support plate are arranged on the left side and the right side on the top of the base respectively, a first reduction motor is arranged on the top of the left side wall of the left support plate, a motor shaft at the right end of the first reduction motor is connected with a rotary shaft, a rotary plate is installed at the right end of the rotary shaft, a pin shaft is arranged on the top of the right end surface of the rotary plate and rotationally connected with a connecting rod, a lifting plate is hinged to the bottom of the connecting rod, and the left side on the bottom of the lifting plate isrotationally connected with a screw rod through a plummer block. The bottom of the screw rod penetrates through the top of the mixing box and is provided with stirring blades, a limiting plate is fixedly arranged between the left support plate and the right support plate through a support, and a telescoping screw rod penetrates through the limiting plate and is in threaded connection with the limiting plate. The spraying-height-adjustable pesticide mixing and spraying device is simple in operation and convenient to control, the screw rod moves up and down through the rotation of the rotary plate, and the screw rod forwards and reversely rotates while moving up and down, so that pesticides are evenly mixed through the stirring blades, and the pesticides are prevented from being precipitated.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a pesticide mixing and spraying device with adjustable spraying height. Background technique [0002] The broad definition of pesticides refers to chemicals used to prevent, eliminate or control diseases, insects, grasses and other harmful organisms that endanger agriculture and forestry, and to regulate, control and affect the metabolism, growth, development and reproduction of plants and harmful organisms. A substance or a mixture of several substances and its preparations that are synthesized or derived from organisms, other natural products and applied biotechnology. In a narrow sense, it refers to a class of drugs used to kill insects, bacteria, and harmful animals (or weeds) to ensure and promote the growth of plants and crops in agricultural production. [0003] In order to ensure the effect of pesticide spraying, it is generally necessary to mix a variety ...

AI Technical Summary

Problems solved by technology

[0003] In order to ensure the effect of pesticide spraying, it is generally necessary to mix a variety of pesticides and water. Ordinary pesticide spraying is sprayed by a manual backpack sprayer, which is heavy in weight. Both mixing and spraying require manual operation, which is time-consuming and laborious. Although some pesticide spraying vehicles can Solve the problem of spraying efficiency, but its operation is inconvenient, the cost of use is high, and the spraying height cannot be adjusted, so it is not suitable for small-area fields
