AI Technical Summary

Technical Problem

When the material conveying structure of existing open-pit coal mines falls on the conveyor belt, the motor power will increase, the rated load will be too large, the motor service life will be shortened, and the machine may be burned. In addition, falling directly on the conveyor belt will damage the conveyor belt and transmission rod, and the equipment is prone to corrosion and rust when used in open air for a long time.

Method used

A material conveying structure for mining open-pit coal mines is designed, including a conveying buffer structure and a protective structure. The conveying buffer structure is adjusted simultaneously by the belt roller, worm gear and meshing gear set to reduce the power consumed by the output motor. The buffer assembly uses elastic rubber braided mesh and damping shock absorbers to buffer material drop to avoid damage to the conveyor belt and transmission rod. The protective structure protects the equipment from corrosion and diffusion of dust from the open-air environment through protective covers, cutting ladders and transparent plates.

Benefits of technology

It effectively reduces motor power consumption, extends the motor service life, avoids damage to the conveyor belt and transmission rod, and protects the equipment from corrosion and diffusion of open-air environments.
