A large inclination angle multi-point unloading chain bucket elevator

technical field

The utility model belongs to the field of material hoisting equipment, in particular to a large-inclination multi-point unloading chain bucket hoist.

Background technique

Bucket elevator is a kind of material continuous transportation machine, which has the characteristics of simple structure, low energy consumption, convenient maintenance, small size, small footprint, small environmental pollution for closed transportation, flexible layout and strong adaptability, etc. It is mainly used in The transportation of powder, granular and small pieces of materials is widely used in industries such as grain, chemical industry, medicine, mining, building materials, cement and ports. The bucket elevator is mainly composed of a traction member, a load-bearing member (hopper), a driving device, a tensioning device, an upper and lower roller (or sprocket), a frame and a cover, etc. In addition, there are auxiliary devices such as safety protection and electrical control. The load-bearing component of the bucket elevator is a hopper, and the traction component is a belt or a chain. The hoppers are fixed on the traction member at certain intervals. The traction member bypasses the rollers or sprockets at the head and bottom of the hoist to form a closed loop system with a rising loaded branch and a descending unloaded branch. The driving device installed at the head of the hoist transmits power to the traction member and the hopper through the head drive drum or sprocket. The material enters the hopper of the hoist through the inlet at the bottom of the elevator, the hopper lifts the material to the head and discharges it at the head, and the material leaving the hopper is discharged through the discharge port at the head of the elevator.

Generally, during the conveying process of materials, the conveying path has a horizontal direction and a vertical direction. The material transportation in the horizontal direction is carried out by machines with horizontal movement characteristics such as belt conveyors or buried scraper conveyors. The material lifting in the vertical direction is generally carried out by vertical Bucket elevator, screw elevator and other equipment are realized, that is to say, at least two different types of conveying equipment are required to complete the material transmission, and the models are fixed, the loading and unloading points are fixed, and multi-point unloading cannot be realized according to the loading and unloading needs.
