机尾螺旋滚筒的设计及推广

Design and Popularization of Tail Screw Roller

在煤矿井下,带式输送机机尾滚筒采用刮煤板将输送带残留余煤清理到集泥槽中,通过人工用拉杆将集泥槽中余煤排出。这种清煤方式陈旧、生产效率低下、容易引起安全事故。根据煤矿井下运输的实际情况及要求,将原有机尾滚筒改为左右螺旋缠绕在筒体上,内部改为锥体结构,增加了自动清煤的功能。给煤矿带来了显著的经济、社会效益。

In the coal mine, belt conveyor tail roller with scraper conveyor will clean up residual coal into mud bath, through the bar will be set manually using the rest of coal discharging. This way of cleaning up coal is old, the production efficiency is low, easily lead to security incidents. According to the actual situation of coal mine transport and requirements, the original tail roller change into spiral wound around the cylinder, the internal change cone structure, and increases the function of automatic cleaning coal. To the coal mine has brought significant economic and social benefits.
