Method and device for cleaning away coal slime in grooves of belt

Abstract

The invention discloses a method and device for cleaning away coal slime in grooves of a belt. The device is arranged on the lower portion of the belt, the device is closely attached to the bottom of the belt and can rhythmically beat the bottom of the belt in an operation process of the belt, and therefore the coal slime in the grooves of the belt is knocked out. The device comprises a carrying roller (3) which is arranged at the bottom of the belt (1), the two ends of the carrying roller (3) are supported on brackets (5) through a carrying roller shaft (7), and the brackets (5) are fixed on an H-shaped frame (2); a protruding structure which can be used for rhythmically beating the belt (1) in the operation process of the belt (1) is arranged on the surface of the carrying roller (3). Thus, in the operation process of the belt, the carrying roller acts on the belt, the coal slime in the grooves of the belt can be cleaned away automatically, the process of manually cleaning away the coal slime is omitted, normal use of the belt is not affected, off tracking of the belt can be prevented, the anti-skid function of the belt is recovered, and working efficiency is improved.

Description

technical field [0001] The invention relates to a method and a device for cleaning coal slime in belt grooves, belonging to the technical field of mine belt transportation. Background technique [0002] Coal mines and other units often use belt conveyors for transportation. Since the underground gangue output is gradually increasing with the underground excavation, the amount of lifting and turning gangue also increases. Mud, etc., in order to have enough friction when turning over gangue and coal slime with water, the belt of the belt conveyor usually uses a non-slip belt with grooves, so that water, thin coal slime, etc. can be pulled up by the belt smoothly. But as time goes by, the coal slime will solidify in the groove. Although the belt machine head has a coal cleaner, but because the coal cleaner is flat, the slime in the belt groove cannot be cleaned cleanly, resulting in a reduction in belt friction. Small, the belt cannot be pulled when turning over mud, water, et...

AI Technical Summary

Problems solved by technology

But as time goes by, the coal slime will solidify in the groove. Although the belt machine head has a coal cleaner, but because the coal cleaner is flat, the slime in the belt groove cannot be cleaned cleanly, resulting in a reduction in belt friction. Small, the belt cannot be pulled when turning over coal mud, water, etc., because of the slope, it will flow to the tail of the machine, which may also cause the belt to deviate, causing great inconvenience to the work
