Bucket elevator operation and maintenance instructions





Bucket elevator is used to aggregate and powder, respectively, to enhance the heat shock screens and weighing device to a horizontal plane.
In the load-bearing structure of the bucket is fixed on two parallel chains and pulleys to run side by side. By acting on the pin shaft and the slide in the vertical guide rod

bracket chain tensioner springs. Bucket elevator by spiral spring tension adjuster to adjust. The flexible conveyor drive shaft

And mounted on the gear box on the swing arm shaft torque by the motor drive.
1 chain tension
Appropriate tension to avoid slipping when running. To check the tension, you should remove the side panel observed.
Hand shake chain, chain should slightly rigid. If desired, the regulator to ensure that both sides of the movable plate and the fixed plate parallel to and equal distance. A

practical approach is to regulate the rotation of each regulator is the same number of turns. Each adjustment, spring compression must not exceed

50%, chain wear, foot shaft bracket close to the lower limit of the guide rod is best replaced with new chain and check whether it is necessary to replace the chain and bucket.
Each chain can be reduced to one or two links in order to correct the chain due to wear caused by long, but this is not a very reasonable method.
In operation, if the shaft or the driven shaft noted every turn, support a large vibration is generated, then the sprocket may be oval.
2 Replace the bucket or changing chain length
Remove Doumen, near the open Doumen, remove the bucket to be replaced and the chain.
Replace Grapples, simply tighten the four nuts that secure it to.
If the hook must be replaced, to thoroughly loosen the regulator and lift the driven shaft to chain relaxation. To ensure that one for a good hook to prevent the chain off.
3 Replace the chain
The fastest and easiest way is to maintain the status quo in the bucket in the case, both from the upper hoist remove two chains.
This step requires a suitable length with a rotation of the crane arm.
In reverse order, repeat the process to have been on the ground for a good chain and bucket mounted beside the swing. To prevent the danger and trouble to make sure when

installing the last bucket chain conveyor does not move.
4. Lubrication
Gearbox - with oiling and oil drain plug.
Bearings - bearing with grease fitting. Or fitted with lubricated bearings.
