Description

Technical Field

[0001] This utility model relates to the field of agricultural equipment technology, and in particular to a controllable spraying device used on a boom sprayer. Background Technology

[0002] Boom sprayers are mechanized equipment used for efficient pesticide application in modern agricultural production. They possess core advantages such as high efficiency, wide spray width, uniform pesticide atomization, and flexible operation, significantly improving application efficiency and reducing reliance on manual labor. Boom sprayers are suitable for pest and disease control in field crops, precision pesticide application in orchards and tea gardens, and operation in the enclosed environment of greenhouses. They are particularly suitable for large-scale planting scenarios, helping modern agriculture reduce costs and increase efficiency. However, most existing boom sprayers have their spraying components directly fixed to the machine body, preventing adjustment of the spraying component angle during use. This results in a wider structure, affecting the movement of the boom sprayer. Furthermore, the nozzles are mostly fixed during use, preventing adjustment based on crop spacing, thus limiting their application.

[0003] Therefore, there is an urgent need for a spraying device that can adjust the angle of the spraying components according to the spacing of the crops to achieve uniform spraying. Utility Model Content

This device allows for angle adjustment and nozzle spacing adjustment based on crop spacing. An angle adjustment component allows for adjustment of the moving rod's angle, enabling it to fit snugly against both sides of the boom sprayer, thus reducing the boom sprayer's width and facilitating movement. A locking component allows for locking the sliding block at different positions on the moving rod, allowing for adjustment based on crop spacing. Furthermore, a rotating spraying component allows for spraying, improving spray uniformity.
