AI Technical Summary

Technical Problem

Existing belt conveyor unloading devices are prone to causing noise from the vibration of baffle plates when large-volume, high-impact bulk materials fall, and are also prone to clogging of chutes, affecting production efficiency.

Method used

The system employs an adjustment mechanism, a distance adjustment mechanism, and an energy storage mechanism. The movement of the slider and longitudinal beam is controlled by an electric push rod. Combined with buffer blocks and material-blocking rails, a material accumulation zone is formed. Large-particle materials are processed using crushing rollers, and impact and dust splashing are reduced by rubber buffer blocks and sealing baffles.

Benefits of technology

It effectively reduces noise, prevents blockages, ensures uniform material distribution, improves production stability and protects the conveyor belt, and reduces the failure rate.

Abstract

This invention discloses a material discharge device for a belt conveyor, relating to the field of belt conveyor technology. It includes a first conveyor belt; a protective cover is provided on the upper part of the first conveyor belt; a material discharge pipe is fixedly connected to the bottom end face of the protective cover; a three-way material discharge frame is fixedly connected to the bottom end face of the material discharge pipe; a first chute is fixedly connected to the lower left part of the three-way material discharge frame; and a second chute is fixedly connected to the lower right part of the three-way material discharge frame. The arrangement of the first and second material-blocking rails creates a material accumulation area on the first or second mounting steel plate, absorbing the vibration generated during material impact. Furthermore, the first and second buffer blocks further absorb the vibration generated by the impact, solving the problem that large-particle bulk materials contain enormous kinetic energy, easily causing significant impact on the barrier plate when falling onto it, leading to vibration and thus significant noise.
