Bucket elevator hopper belt slippage

( 1 ) bucket machine is to use the hopper with the first round of the friction torque between the drive shaft for elevator materials , unpredictable enough hopper belt tension

will cause the hopper with skid. At this time , you should immediately shut down, adjust the belt tensioning device to tighten the hopper . If you can not make the hopper belt

tensioning device is fully tensioned , said

Ming tensioning device trip is too coal production line short, should be re- adjusted .
The correct solution is : untie bucket elevator hopper with coupling to the bottom tensioning device on the wheel adjusted to the highest position , the hopper with bucket

elevator into the hoist head through the first round and bottom round , and both connected, the hopper with bucket elevator in the tensioner without sheets

Tight state. Then the tensioning stone feeding machine device is fully tensioned. At this point tensioning device untapped tension adjustment screw stroke of not less than 50% of the whole trip .
( 2 ) bucket elevator overload , resistance torque increases, resulting in the hopper with skid. You should reduce the amount of material fed and seeks uniform feeding . If you

reduce the feed rate , still not improve skid, sit inside the machine may be too much or material accumulation mentor material hopper are stuck , you should stop to check

, Troubleshooting.
( 3 ) bucket elevator hopper nose wheel shaft and the inner surface is too smooth head with round shafts and hopper band surface is too smooth , so that the friction between

them decreases, resulting in the hopper with skid. At this time, the hopper with the shaft and the inner surface coated with a layer of adhesive to increase the friction.
( 4 ) bucket elevator nose wheel and wheel bearing rotation not working head end and a bottom wheel bearing wheel rotation ineffective, moment of resistance increases, causing

the hopper with skid. Then washable refueling or replace bearings.
