Description

Coal rolling prevention device at roller of belt conveyor

Technical Field

The utility model relates to a band conveyer field specifically is a coal device is prevented rolling up by belt feeder cylinder department.

Background

In some coal mines, a main inclined shaft strong belt (such as a belt with belt parameters of 1.4m, belt speed of 3.15m/s and designed transport capacity of 1640T/H) is arranged, a large amount of raw coal produced in a panel area is carried, and when the belt runs to the head, the belt directly falls on another belt through a coal leaking barrel with the depth of about 3 meters (the belt width of 1.4m, the belt speed of 2.5m/s and the designed transport capacity of 1580T/H). If the powerful belt of main inclined shaft increases the belt in production process and piles up fortune coal volume, when raw coal operation falls another belt, because preceding stage belt speed, transport capacity lag cause the excessive coal that takes place after the piling up of main inclined shaft belt head coal section of thick bamboo, the coal that later overflows is pulled to pressing belt drum department through the end belt of coal lifting drum department, and is died the cylinder stopper, and belt drum is caused easily after being died by the foreign matter stopper: the belt passes through the roller and is extruded with foreign matters to cause damage to the belt in different degrees; the joint is changed and damaged; the belt can bulge out to form bubbles in the extrusion process, so that the service life of the belt is reduced; the current is increased to damage the motor; the joint is broken after the running resistance of the roller is increased due to the blockage, so that the belt breakage accident is caused. Therefore, in order to solve these problems, it is necessary to prevent the coal from being rolled up in the drum.
