Study Of Vibration Characteristics And Transport Properties Of Spiral Conveyor Device Of Coal Auger

A Coal auger is an important equipment in thin coal seam mining coal mine, it's using in coal mine is increasing, and more attention has being attracted to the work capability of it. Therefore, it is valuable and practical significance to study the vibration characteristics and transport properties of spiral conveyor device in the transportation process.This article analyzes the works of spiral conveyor device of coal auger. Obtains the effect of vibration frequency of spiral conveyor device of coal auger's structural parameters and motion parameters by analyzing vibration using the theory of mechanical vibration Obtains the displacement response of key node by analyzing finite element model using ANSYS software and the theory of mechanical dynamics. Studying the transmission performance of spiral conveyor device and the parameters affected the transmission performance. Structure parameters of the spiral conveyor device are optimized by using AFSA algorithm and by taking the diameter, spiral blade lead, helix angle and spiral blade thickness of spiral conveyor device as design parameters, choosing lowest secondary crushing rate of spiral conveyor device as optimal objective. To ensure the lowest secondary crushing rate in the premise of guaranteed transmission performance.
