The bucket elevator is a specialized equipment used for vertical material transportation.
The materials enter from the bottom and circulate through the bucket, chain or belt, continuously lifting grains, particles, powders, etc. from the lower level to the higher level. After reaching the top, the materials are discharged under the action of centrifugal force and gravity, and the empty bucket falls back into the circulation process to achieve continuous and stable lifting.
The entire machine operates in a closed manner, featuring a large conveying capacity, stable operation, small floor space, and low risk of material spillage. It is widely used in loading and transportation operations in industries such as agriculture, grains, feed, and building materials.
The main structure of the bucket elevator:
The bucket elevator is mainly composed of the head, buckets, lifting belt (chain), cylinder, base, and other components.
Working Principle:
The working principle of this machine is that the elevator belt /elevator chain is wound around the head pulley and the tail pulley. Along the entire length of the hopper belt, loading bins for materials are fixed at certain intervals using hopper screws.
To prevent material dispersion and dust flying, the entire structure is sealed with an outer shell. The elevator is driven by a drive motor to rotate through the head pulley, thereby driving the elevator belt /elevator chain to operate.
During operation, materials enter the machine body through the feed port, and then the hopper lifts the materials to the machine head. When the hopper passes around the head pulley, the materials are thrown out and flow out of the discharge port outside the machine.
Features:
Safe and reliable operation, simple structure, complete functions, good sealing performance, low noise. Particularly, with high output, low backflow, low failure rate and long service life, it ensures the efficiency of use. Moreover, it is applicable to both powder and granular materials, equipped with explosion-proof cover and pressure balance device. It is currently an ideal lifting equipment.
The main components of the bucket elevator: traction assembly, elevator buckets, head pulleys and boot pulleys.
The traction assembly mainly consists of: elevator belt and elevator chain.
Elevator Belt
The elevator belts mainly include PVC solid woven elevator belts, reinforced-polyester elevator belts,high-strength flat rubber belts and ordinary flat rubber belts. Select the corresponding material according to the working conditions.
Main features: The material is flexible and has a low elongation rate, making it less prone to sagging or deviating; it can fix the hopper and is compatible with equipment for sealed transportation, featuring low noise and long service life, meeting the continuous and stable lifting requirements in agriculture.
Elevator Chain
Common types of chains include high-strength round link chains,elevator chains, and NE elevator chains.
Main features: high load-bearing capacity, resistance to pulling force, wear resistance and corrosion resistance, etc.
Elevator Bucket
The main materials of the elevator bucket include plastic, nylon, as well as those made by pressing steel plates and welding carbon steel.
Head Pulleys and Boot Pulleys
The main functions of the head pulley:
- As the driving wheel, it is connected to the motor and reducer, driving the chain or elevatorbelt to rotate;
- By generating centrifugal force through the rotational speed, the bucketscan smoothly discharge materials, ensuring smooth transportation.
The main purposes of the head pulley lagging pads
- To increase friction, prevent the belt or chain from slipping, and improve the transmission efficiency.
- To protect the metal surface of the head pulley, reduce wear, impact and noise, and extend the service life.
- To buffer and dampen vibrations, make the operation more stable, and reduce the impact on the bucketand traction components.
- The insert-type structure is convenient for local replacement, making maintenance simple and reducing maintenance costs.
- Anti-slip and wear-resistant, ensuring stable discharge, reducing deviation and abnormal wear.
The main functions of the boot pulley:
- As the driven wheel, it cooperates with the head wheel to form a circulation loop and tension the traction components (chain / belt);
- Prevent slippage and deviation, ensure the smooth operation of the hopper, and facilitate equipment debugging and maintenance.
