Hopper form of bucket elevator

Bucket elevator is divided into deep bucket, shallow bucket and triangle bucket. According to the different working speed of bucket elevator and the characteristics of transported materials, different hopper forms can be adopted. The angle between the hopper and the rear wall of hopper is large, each hopper can load more materials, but it is difficult to unload, which is suitable for transporting dry loose materials; the angle between the hopper of shallow hopper and the rear wall of hopper is small, the loading capacity of each hopper is small, but it is easy to unload, which is suitable for transporting wet and viscous materials. The deep and shallow buckets are fixed on the traction components at a certain distance along the length direction of the traction components. The hopper is a triangular hopper with a guide side. This hopper is arranged intensively one by one in the elevator. When the hopper bypasses the upper sprocket wheel for unloading, the two guide sides and the front wall of the former hopper form the unloading guide groove of the latter hopper. This hopper is suitable for transporting heavy, semi abrasive and highly abrasive block materials.

Hopper type is divided into shallow bucket, deep bucket and triangle bucket. Shallow bucket: the angle between the bucket mouth and the back wall is small, and the material can be loaded is small, but the unloading is easy. It is suitable for transporting materials with poor fluidity such as cement, wet sand and gypsum powder. Deep hopper and shallow hopper are mostly made of steel plate by welding or direct stamping, and can also be cast by malleable cast iron. In order to reduce the dead weight of hopper, they can also be made of fiberglass.

The properties of the lifted materials have a great influence on the shape and structure design of hopper. The selection of hopper can be summarized as follows: for abrasive materials, hopper is required to have a high-strength hopper along the front edge of the mouth to reduce the abrasion of hopper when excavating materials on products with high water content and materials with poor fluidity. Hopper with high front edge of the mouth should be used, so as to improve the energy for materials that are easy to suspend. Pores should be drilled on the hopper to help the materials settle and easy to bond The shallow hopper with round bottom can reduce the accumulation of material in the dead corner of hopper.
