Description

Technical Field

[0001] The present application relates to the technical field of bucket elevator sprockets, and in particular to a bucket elevator sprocket with detachable and replaceable sprocket teeth. Background Art

[0002] Bucket elevator, as a common vertical conveying equipment, is widely used in cement, mining, chemical and grain industries. It drives the bucket through a continuous chain to lift the material from a low place to a high place, thus realizing the vertical conveying of the material. As one of the key components of the bucket elevator, the sprocket is responsible for driving the movement of the chain and the bucket.

[0003] During the use of chain-plate bucket elevators, the head and tail sprockets are in direct contact with the scraper chain links, and are subject to greater friction and impact. Due to the harsh working environment, the sprocket teeth are subject to greater wear, which has become one of the key points of bucket elevator maintenance. However, traditional sprockets and shafts are often tightly assembled, and the sprocket teeth are integrally formed with the wheel body. Once the sprocket teeth are worn, the entire set of sprockets often needs to be replaced, increasing maintenance costs. At the same time, the replaced sprockets are often directly discarded due to their lack of repair value, resulting in a waste of resources, so this needs to be improved. Utility Model Content
