AI Technical Summary
Existing spiral conveyor circulating grain dryers are prone to blockage during grain conveying due to the high viscosity and moisture content of the grain, which causes the grain to stick to the inner wall of the feed pipe, affecting efficiency and increasing the risk of failure. Furthermore, the screen replacement operation is cumbersome and time-consuming, reducing the equipment's versatility and ease of use.
The spring inside the protective shell drives the scraper to remove the adhering material from the inner wall of the feed pipe, and the design of the pin and spring enables quick screen replacement, simplifying the operation process.
It effectively prevents the feed pipe from clogging, improves the efficiency of grain conveying and the continuity of the equipment, and simplifies the screen replacement process, thereby enhancing the versatility and working efficiency of the equipment.
