A plant foliar spraying device

Abstract

The invention discloses a plant leaf spraying device. The plant leaf spraying device comprises a spraying body, a water pump, a liquid conveying hose, a spray rod and a liquid inlet. The liquid inlet is formed in the top of the spraying body, and a liquid inlet cover is arranged on the liquid inlet. The water pump is arranged on the bottom of the spraying body. One end of the liquid conveying hose is connected with the water pump, and the other end of the liquid conveying hose is connected with the spray rod. The spray rod comprises an inner rod body and an outer rod body, wherein the inner rod body is in sliding connection with the outer rod body, the top of the inner rod body is movably connected with a spray head, a square opening is formed in the surface of the outer rod body, and a handle is arranged at the position, corresponding to the square opening, of the inner rod body. According to the plant leaf spraying device, by arranging the structure that the inner rod body slides relative to the outer rod body, the inner rod body relatively slides through the handle which is arranged on the inner rod body, and the spraying angle of the spray head is changed; and meanwhile a stirring mechanism is arranged, pesticide liquid can be stirred in real time, and uniformity of pesticide liquid mixing is effectively guaranteed.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a plant foliage spraying device. Background technique [0002] Plant foliar spraying technology has two functions. On the one hand, spraying insecticides and fungicides can effectively eliminate the damage of diseases, insect pests and fungi. On the other hand, spraying plant hormones and foliar fertilizers can increase the growth and seed setting rate of plants. As an important means of insecticide and root topdressing, plant foliar spraying technology is the most effective method to improve plant resistance, supplement the special needs of certain nutrients during the growth period of plants, and regulate plant growth and development. A good spraying device should not only satisfy the uniform spraying on the foliage, but also have an adjustable angle to meet spraying in all directions. [0003] According to the Chinese patent application number CN201520003507.2, an electr...

Problems solved by technology

[0004] Although the above-mentioned solution solves the problem that the traditional sprayer needs to hold the spray rod with one hand and press the pressure rod with the other hand, which is labor-intensive, it does not give any advice on how to change the spraying angle of the nozzle and how to make the pesticide mix more evenly. corresponding technical solutions
