Common failures and treatment methods of bucket elevator

Dec 06, 2021

Bucket elevator use the frictional torque between the hopper belt and the drive shaft of the head wheel to lift materials. If the tension of the hopper belt is not enough, it will cause the hopper belt to slip. At this time, stop the machine immediately and adjust the tensioning device to tighten the hopper belt. If the tensioning device cannot fully tension the hopper belt, it means that the stroke of the tensioning device is too short and should be re-adjusted.
The correct solution is: untie the joint of the hopper belt, adjust the tensioning device on the bottom wheel to the highest position, put the hopper belt into the head of the hoist, pass through the head wheel and the bottom wheel, and connect it head and tail to make the hopper The belt is in a state of being tensioned but not tensioned. Then fully tension the tensioning device. At this time, the unused tensioning stroke of the adjusting screw of the tensioning device should not be less than 50% of the full stroke.
The hoist hopper belt is usually canvas belt, and sometimes tape and chain are also used. Under the combined effect of various failures, canvas belts and tapes are prone to tearing, which is one of the most serious failures. Generally, the deviation of the hopper belt and the falling off of the hopper are most likely to cause the hopper to tear. The reasons should be found out in a timely and comprehensive manner, and the faults should be eliminated. In addition, foreign matter with sharp edges mixed into the material will also crack the hopper belt. Therefore, in production, steel mesh or iron-absorbing stone should be installed at the feed inlet to prevent large foreign objects from falling into the machine base.
