Description

Technical Field

[0001] The utility model relates to the technical field of pesticide sprayers, in particular to an agricultural plant protection pesticide sprayer. Background Art

[0002] Agricultural plant protection refers to plant protection work in agricultural production, aiming to prevent, control, and reduce the impact of adverse factors such as pests, diseases, weeds, and weather on crops, thereby ensuring crop growth and yield. Plant protection work includes a series of management and control measures to ensure the health and production efficiency of crops. Sprayers are mechanical equipment used to spray pesticides, herbicides, growth regulators, and other plant protection agents. They can effectively and evenly spray the liquid medicine on crops in farmland or orchards, thereby achieving the prevention and control of pests, diseases, and weeds.

[0003] In the prior art, Chinese patent application number "201720363473.7" discloses a pesticide sprayer, comprising a pesticide sprayer body, a row of front running wheels being provided at the bottom end of the pesticide sprayer body, a row of rear running wheels being provided at the bottom end of the pesticide sprayer body, a pesticide tank being connected to the rear of the pesticide sprayer body, a handrail being installed on the pesticide sprayer body, a first telescopic adjustment rod being provided at the upper end, a second telescopic adjustment rod being provided at the upper end, a spray tank being provided at the upper ends of the first telescopic adjustment rod and the second telescopic adjustment rod, and pesticide solution being filled in the spray tank; an oblique rod being provided at one side of the upper end of the pesticide sprayer body, a vertical rod being vertically installed at the upper end of the oblique rod, a regulator being movably installed at the upper end of the vertical rod, a telescopic rod being provided at the side end of the vertical rod, a spray gun rod being installed at the end of the regulator, a plurality of nozzles being installed on the spray gun rod, a hose being connected between one end of the spray gun rod and the spray tank, and a pesticide pump being installed on the hose;

[0004] The above patent can change the spraying angle of the spray barrel to a certain extent, but in actual operation, multiple telescopic cylinders are fixed at the head and tail of the spray pipe to adjust the spray angle. Adding multiple telescopic cylinder adjustment mechanisms will increase the complexity of the system and require additional control circuits, sensors and mechanical components, which will increase the maintenance cost and failure risk of the system, reduce the overall work efficiency and increase the production and manufacturing costs. It is necessary to improve the existing technology. To this end, we propose an agricultural plant protection sprayer to solve the above problems. Utility Model Content

[0015] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0016] The sprayer in this utility model is based on a mechanical transmission system and control device. When using this device, the servo motor is first activated to drive the winding roller to wind a surface tension wire. This pulls the tension wire onto a moving seat at the other end, causing the moving seat to rotate about the axis of the mounting plate. In the center of the mounting plate, a rotating roller is fixed to the tail of the spray head, while a fixed roller on one side of the moving seat is connected to the head of the spray head. This allows the spray head to rotate around its tail with the moving seat, thereby changing the spray angle of the spray head. When the servo motor is reversed, the tension wire loosens, and the moving seat returns to its original position under the action of a return spring, returning the spray head to its original position. This allows the user to flexibly change the spray angle of the spray head according to actual needs. The device can precisely control the spray angle of the spray head, improving spraying accuracy and efficiency. This allows for flexible adjustment of the spray angle of the spray head. The overall production and use costs are low, providing a convenient and efficient plant protection solution for agricultural production. BRIEF DESCRIPTION OF THE DRAWINGS
