Description

Coal sweeping device for tail roller of belt conveyor in coal mine production

Technical Field

The utility model belongs to the field of coal mine production, and particularly relates to a coal sweeping device for a tail roller of a rubber belt conveyor in coal mine production.

Background

At present, when the rubber belt conveyor for the underground coal mine conveying system is used for conveying and delivering goods, the goods on the belt can not be completely unloaded, so that the goods are seriously accumulated below the unloading arm of the machine head of the rubber belt conveyor, below the driving roller, below the travelling trolley and below other flower frames and under the bottom carrier roller, the normal operation of the rubber belt conveyor is seriously influenced, and the normal gangue discharge of the gangue discharge system is restricted. Therefore, the strip-shaped coal sweeping device and the coal shoveling plate are arranged on the machine head, the roller side and the upper side of the belt below the tail of the belt conveyor and are used for cleaning the product which is not unloaded completely on the belt for the second time, so that the product accumulation on the machine head, the lower part of the flower stand and the lower part of the carrier roller of the belt conveyor is reduced. After the strip-shaped coal sweeper is used for a period of time, the belt on the coal sweeper is continuously worn by the belt conveyor in the running process, so that a gap exists between the belt of the belt conveyor and the belt of the coal sweeper, the action of the strip-shaped coal sweeper is greatly reduced, and the belt on the coal sweeper needs to be replaced or the position of the coal sweeper needs to be adjusted at intervals.

In the process of discharging, small gangue often falls to a bottom belt, and the gangue is transported and rolled into a tail roller through the bottom belt, so that the belt is padded and broken, a plurality of cracks appear, and the gangue discharge and discharging of the TBM hard rock tunneling machine are seriously influenced; the frequency of occurrence of the deviation faults of the two-way belt is increased; the abrasion of the tail roller is also caused, and the failure rate is obviously increased. Therefore, the two-conveyor belt of the TBM hard rock tunneling machine breaks and deviates and spills goods, so that the personnel overhaul workload and strength are increased in an intangible way, and abnormal abrasion to TBM hard rock tunneling machine equipment is caused, and therefore the TBM shipment and tunneling efficiency is reduced. After the strip-shaped coal sweeper is arranged on the upper side of the lower belt of the TBM hard rock tunneling machine and runs for a period of time, the belt abrasion speed on the coal sweeper is very fast and needs to be regulated almost once every day because the speed of the secondary belt of the TBM hard rock tunneling machine is 2.2 meters per second and the belt tension is about 100bar, so that the overhaul intensity and the workload of overhaul personnel of the TBM hard rock tunneling machine are increased intangibly. Therefore, a coal sweeper capable of freely moving up and down is required to be designed so as to meet the production requirement of the current TBM hard rock tunneling machine.
