Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically to a high-efficiency screening and feeding belt structure. Background Technology

[0002] Conveyor belts, also known as transport belts, are rubber and fiber / metal composite products, or plastic and fabric composite products, used in belt conveyors to carry and transport materials. Conveyor belts are widely used in industries such as cement, coking, metallurgy, chemicals, and steel for short-distance and small-capacity conveying applications.

[0003] A relevant reference is Chinese utility model patent CN217043482U, which discloses a screening belt device, including a frame and a base plate. A belt is positioned between the two ends of the frame, and several discharge holes are formed in the middle of the belt. The belt includes an upper belt and a lower belt. Material with a particle size smaller than the discharge holes, transported on the upper belt, falls through the discharge holes. The base plate is located between the lower and upper belts, with its two ends respectively mounted on the two ends of the frame. The base plate is inclined relative to the upper belt, with one side extending beyond the side of the upper belt. This allows the base plate to receive the material passing through the discharge holes, and the material then slides along the base plate under gravity for collection. This single belt device achieves multiple material classifications, saving resources and shortening the installation period.

[0004] Material is conveyed to the screening equipment by lifting it to the inlet of the screening device via a belt. In the existing belt structure, after receiving the material, the center of the belt will sink downward under the influence of the weight of the material, causing the material to concentrate in the center of the belt. After entering the screening equipment, the material will accumulate and affect the screening. At the same time, the existing belt structure cannot control the thickness of the material accumulation, resulting in inconsistent material entering the screening equipment, and the conveying speed cannot be kept consistent, which affects the screening.

[0028] Specifically, the support rod 1 supports the limiting plate 11, the limiting roller 12 at the top of the limiting plate 11 and the drive roller 13 limit the shape of the belt 16, and the support shaft 15 supports the belt 16.
