The lifting belt assembly of the shot blasting machine (lifting belt assembly) is made up of (abrasion-resistant conveyor belt, lifting bucket, crab shell screw, nut installation and fixing). The lifting bucket must have high impact resistance and elasticity, and the elevator is running When it collides with a metal foreign body or a casing, it can produce elastic shielding, reduce noise, and avoid the frequent deformation of the hopper, tearing of the conveyor belt and other failures. Thereby, the equipment load of the hoist is reduced, the power consumption is saved, the use time of the equipment is prolonged, the maintenance man-hours are reduced, and the production cost is reduced. At the same time, the hoisting bucket must also have the performance of inverted netting: when the hopper is lifting the steel shot, it is often unable to completely pour out the net, which will be worn for a long time, so the appropriate curvature and reinforcing ribs can play a role in wear resistance.
