Bucket elevator by the shell, traction parts (conveyor chain), hopper, driving wheel (head wheel), steering wheel (tail wheel), tensioning device, guide device, feeding port (feed port) and discharge port (discharge port).
Hopper:
a, cylindrical bucket: deep bucket, bucket mouth is 65 degrees inclined, the depth is large, for dry, good liquidity, good scattering granular material conveying.
Shallow hopper: Mouth is 45 degrees inclined inclined, small depth, used for wet and fluid granular materials.
Deep hopper: The general material of deep hopper is dry and has good liquidity.
Triangle hopper: the material is generally directional free flow discharge.
b, sharp corner bucket: its side wall extends to the bottom plate, become the retaining side, unloading, material can be along the retaining side of a bucket and the bottom plate formed by the groove unloading stop, suitable for thick and heavy block material transport.
Traction member:
(a) Rubber belt: with screws and elastic gaskets fixed in the belt mouth, belt than bucket width 35~40mm, general belt conveying temperature does not exceed 60℃ material, heat-resistant belt can transport up to 150℃ material.
(b) Chain: the single chain is fixedly connected to the rear wall of the hopper; The double chain is attached to both sides of the hopper. Chain hoist when the hopper width is 160~250mm using single chain, when the hopper is 320~630mm using double chain, the main disadvantage is the wear between the chain, increase the number of maintenance.
Sprocket:
Drive sprocket on bucket elevator. A sprocket is a solid or spoked gear that engages with a roller chain to transmit motion. The sprocket is a solid or spoked gear that engages with a roller chain to transmit motion.
Sprocket tooth shape design: sprocket tooth shape must ensure that the chain energy saving smooth and free to enter and exit engagement, as far as possible to reduce the impact and contact stress of the chain when meshing, and to be easy to process. Sprocket material should ensure that the teeth have enough strength and wear resistance, so the sprocket tooth surface is generally after heat treatment, so that it reaches a certain hardness.
