AI Technical Summary

⚠Technical Problem

Traditional hoppers are prone to blockage and uncontrolled material flow when material directly impacts the bottom of the hopper during feeding, causing downstream blockage, leakage, belt misalignment, and shutdown. Existing flow guiding structures are ineffective and increase maintenance difficulties.

⚗Method used

The belt conveyor hopper designed to prevent material blockage uses a square inlet and a rectangular outlet to form a horn-shaped feed section. Combined with a buffer diversion mechanism and a triangular diverter, the diverter is driven by a rotating shaft to swing and disperse the material flow. A flow limiter is set on the rear side plate to regulate the flow rate.

🎯Benefits of technology

It effectively reduces material blockage, improves conveyor stability and efficiency, enables precise control of material flow, prevents conveyor belt impact, and increases conveyor belt friction to prevent slippage.

Abstract

This utility model discloses a hopper for an anti-clogging conveyor belt, comprising a hopper body and a conveyor belt body, wherein the conveyor belt body is located below the hopper body. The hopper body includes a feeding section and a discharging section. The top of the feeding section is a square feeding port, and the bottom of the discharging section is a rectangular discharging port. The width of the discharging port is equal to the width of the square feeding port. The discharging section is equipped with a buffer diversion mechanism, including a rotating shaft and a diverter with a triangular cross-section. The rotating shaft is rotatably connected between two opposite front and rear side plates of the discharging section and is located at the top of the front and rear side plates. The top of the diverter is fixedly connected to the rotating shaft. This utility model disperses the material flow through the triangular diverter, reducing the impact of material flow on the conveyor belt. The diverter can rotate under the drive of the rotating shaft and swing when the material flow impacts, further dispersing the material. The conveying mechanism of this utility model uses an anti-slip layer to prevent slippage and improve conveying efficiency.
