The bottom surface of the roller frame 4 is fixedly provided with a balancing weight 7.
The balancing weight 7 is fixed on the bottom surface of the roller frame 4 through a steel wire rope 6.
The balancing weight 7 is fixed through the steel wire rope 6, and the fixing is firm, safe and reliable.
The surface of the drum 10 is provided with a conveyor belt 8, the conveyor belt 8 running in the direction of rotation of the drum 10.
The roller 10 is in contact with the surface of the conveyor belt 8, so that smooth running of the conveyor belt 8 in the working process can be ensured, and meanwhile, the running direction of the conveyor belt 8 is guided.
The beneficial effects of the utility model are as follows:
1) When the conveyor belt 8 starts and stops, the balancing weight 7 moves up and down for 1-2 times, meanwhile, because the pulley block 1 and the sliding rail 2 generate point contact rolling friction, abnormal sound cannot be generated, the pulley block 1 drives the roller frame 4 to move up and down along the sliding rail 2 smoothly in the process of moving up and down, the up and down moving process basically keeps a uniform moving state, the situation of no blocking occurs, and further the sliding resistance of the balancing weight of the belt conveyor can be reduced.
2) The device simple structure, simple installation, processing cost of manufacture are low, excellent in use effect, can use for a long time after once making is accomplished, long service life.
