Description

A Belt Sticky Coal Cleaning and Recovery Machine

technical field

The invention belongs to the field of belt conveyors, in particular to a belt sticky coal cleaning and recycling machine.

Background technique

The traditional coal mine underground belt conveyor does not have a cleaning device. When the coal is soft or the pulverized coal and water are mixed into mud, it is easy to adhere to the belt and cause random spills during the rotation process. If it is not cleaned in time The accumulated coal will stick to the back of the belt after being piled up high, and squeezed on the roller so that the belt conveyor cannot operate normally, that is, it will cause downtime or belt slipping and tearing, which will affect the production progress of the coal mine underground.

Usually, two to three people will be arranged to clean up the randomly spilled coal along the transportation line on the belt conveyor, that is, relying on manpower to shovel the coal that has been spilled on the ground to the ground with a shovel. On the upper belt of the belt conveyor, this cleaning method not only increases the cost of employment, but also this kind of cleaning work is also a very heavy physical labor. Completing such a heavy workload in the harsh working environment of the underground coal mine is extremely harmful to the health of the operators. On the other hand, because the belt conveyor transports coal under strong power, the operators are constantly running. Coal shoveling operation next to the belt conveyor is particularly prone to the operator's hair, clothing or tools being involved in the belt conveyor roller, causing bodily injury or even death to the operator. The operator of the operation poses a safety hazard.

At present, a belt conveyor coal cleaner has appeared on the market, which can shovel off the sticky coal adhering to the belt, but the shoveled coal still needs to be shipped by a special person, which is not only time-consuming and laborious, but also has the above-mentioned problems.
