AI Technical Summary

Technical Problem

During material transfer, belt conveyors are prone to interlocking shutdowns or belt tearing due to the intrusion of long, thin foreign objects. Existing technologies lack effective interception measures.

Method used

A tear-resistant device was designed, comprising a foreign object blocking crossbar, a buffer seat, a foreign object receiving platform, a machine head chute, a buffer spring, and a fixed base. The foreign object blocking crossbar intercepts long strip-shaped foreign objects, and the buffer spring and alarm device provide timely alarm and protection.

Benefits of technology

It effectively intercepts and alerts to long, thin foreign objects, preventing belt conveyor shutdowns and belt damage, thus improving the operational stability and safety of the conveyor.
