AI Technical Summary
The existing spraying device cannot adjust the shape of the spray head during the spraying of pesticides, resulting in low spray flexibility and efficiency. It is necessary to disassemble the spray head before it can be replaced to prevent clogging.
An anti-blocking spraying device is designed, including a spray tube, a sealing cover, a slide rod, an adjustment sleeve and an adjustment head. By rotating the adjustment sleeve and the adjustment head, the overlap angle of the spray port is changed, thereby changing the pesticide spraying. Track and ensure sealing by sealing piston and rubber ring.
The spray trajectory is flexibly adjusted during the spraying process of pesticides, which improves the spraying efficiency, and fixes the adjustment head position through annular tooth and springs to avoid changing the angle due to water flow impact, which enhances the stability of the device.
