Description

Technical Field

[0001] This utility model belongs to the field of bucket elevators, and specifically relates to a lightweight transmission wheel for bucket elevators. Background Technology

[0002] A bucket elevator is a continuous conveying machine that vertically lifts materials using a series of buckets evenly fixed to a traction component. Bucket elevators are suitable for lifting materials from low to high places. After the material is fed into the buckets via a vibrating table, the machine automatically and continuously transports it upwards. The conveying speed can be adjusted according to the conveying capacity, and the lifting height can be selected as needed. The drive mechanism of a bucket elevator includes two vertically aligned drive wheels, with a vertical drive belt between them. Buckets are spaced apart on the drive belt, and each drive wheel is connected to a drive motor. Currently, the drive wheels of bucket elevators are too heavy, increasing the energy consumption of the drive motor, resulting in energy waste. Utility Model Content

[0003] The purpose of this invention is to provide a lightweight transmission wheel for bucket elevators, which can reduce the weight of the transmission wheel, increase its strength, reduce the driving energy consumption of the motor, and save energy.

[0004] The purpose of this utility model is achieved as follows: a lightweight transmission wheel for a bucket elevator includes a central shaft, a central disc is sleeved in the middle of the central shaft, and a front reinforcing ring and a rear reinforcing ring are respectively arranged at the front and rear ends of the outer edge of the central disc. A plurality of front reinforcing rods are arranged circumferentially between the front reinforcing ring and the outer edge of the central disc, and a plurality of rear reinforcing rods are arranged circumferentially between the rear reinforcing ring and the outer edge of the central disc.

[0005] This invention features a central disc mounted on its central shaft. The central disc is connected to and fixed to a front reinforcing ring and a rear reinforcing ring via several circumferentially distributed front and rear reinforcing rods. A conveyor belt passes around the outer circumference of the wheel body formed by the front and rear reinforcing rings for transmission. The wheel structure is lighter while maintaining its strength. Compared to existing technologies, this invention offers the advantages of reducing the weight of the bucket elevator's drive wheel, increasing its strength, reducing motor drive energy consumption, and saving energy. This invention can be used on the upper and lower drive wheels of a bucket elevator.

[0006] As a further improvement of this utility model, both the front reinforcing rod and the rear reinforcing rod are parallel to the length direction of the central axis.

[0007] As a further improvement of this utility model, the central disk includes a circular disk core sleeved on a central shaft. A plurality of connecting spokes are evenly distributed circumferentially around the outer periphery of the disk core. The connecting spokes are radially arranged, and the outer periphery of each connecting spoke is fixed to an outer ring body. The outer ring body is coaxially arranged with the circular disk core. The connecting spokes connect the outer ring body and the disk core.

[0008] As a further improvement of this utility model, the front reinforcing rod is disposed between the outer ring body and the front reinforcing ring, and the rear reinforcing rod is disposed between the outer ring body and the rear reinforcing ring.

[0009] As a further improvement of this utility model, the center of the disk has a mounting cylinder, the length of which is greater than the thickness of the disk. A shaft hole corresponding to the central shaft is formed on the mounting cylinder. The central shaft has an outer mounting step in the middle. The mounting cylinder is fitted onto the outer step through the shaft hole, the length of which is greater than the length of the outer step. A limiting ring block is fitted at both the front and rear ends of the outer step inside the shaft hole of the mounting cylinder. The limiting ring block abuts against the outer step. Each limiting ring block is fixedly connected to the mounting cylinder by several fasteners evenly distributed circumferentially. The two limiting ring blocks of the mounting cylinder of the central disk block block the front and rear ends of the outer step, providing axial limitation. The central shaft is also positioned with the mounting cylinder by a key block. Attached Figure Description
