AI Technical Summary
Technical Problem
Existing pesticide spraying equipment in eggplant greenhouses suffers from uneven spraying and excessively long spraying times.
Method used
The system employs a combination of a chemical tube, a motor, an electric actuator, and a spraying device. The motor drives the rotating sleeve to rotate, the lever slides, and the movable rod rotates spherically, allowing for flexible adjustment of the angle and direction of the spiral nozzle. Combined with the adaptive deformation of the flexible sealing sleeve, uniform spraying is achieved.
Benefits of technology
It enables uniform spraying of pesticides in eggplant greenhouses, and allows spraying to be adjusted at any angle and direction, improving spraying efficiency and uniformity.

Abstract
This utility model relates to the technical field of pesticide spraying equipment, and discloses a pesticide spraying device for greenhouse cultivation of eggplant. It achieves adjustment of the spraying direction by setting up a pesticide tube, motor, spraying device, electric push rod, etc. Simultaneous starting of the two motors causes the motors to drive the rotating sleeve through the output shaft and coupling. When the rotating sleeve rotates, the push rod rotates synchronously with the pesticide tube through the movement of the straight groove. Because the position of the pesticide tube is restricted by the gasket, the position of the push rod will adaptively adjust itself within the straight groove during rotation. The movable rod, through the spherical rotation of the hemispherical shell and the spherical shell located inside the pesticide tube and the spherical sleeve respectively, adjusts the angle of the movable rod, allowing the spiral nozzle to be sprayed on the plants on the lateral side, thus achieving the effect of lateral angle adjustment.
