AI Technical Summary
Existing concrete feeding devices are prone to concrete sticking to the discharge port during use, causing blockages and affecting normal operation.
A concrete feeding device including a lifting mechanism and a mixing mechanism was designed. The inner wall of the discharge port is cleaned by a scraper assembly, and the size of the discharge port is controlled by a servo motor to achieve automated cleaning and flow regulation.
It effectively prevents blockage at the discharge port, improves material feeding efficiency and operational efficiency, and ensures the continuity and stability of concrete feeding.
