Background The feeding elevator is a general device in a tobacco shred production line, is mainly used for conveying and lifting tobacco materials, and is one of key devices essential to a tobacco shred production process. In the tobacco shred production process, a great amount of dust and powder are generated from tobacco materials, and the dust and the powder are easy to accumulate in the inner cavity, the cross brace, the back plate and other parts of the lifting belt of the feeding elevator, so that a sanitary dead angle which is difficult to clean is formed. The accumulated material residues not only can influence the operation stability of the feeding elevator, but also can become breeding sources of insect pests such as tobacco beetles and the like, directly pollute tobacco materials, seriously influence the quality of tobacco products, and can not meet strict production sanitary requirements of tobacco industry. In order to ensure the production quality and meet the industry sanitary standard, the interior of the feeding elevator needs to be thoroughly cleaned and maintained regularly. However, the existing feeding elevator has a plurality of problems to be solved in the cleaning and maintaining process, so that the equipment maintenance efficiency and the operation safety are severely limited, firstly, the protection plate of the existing feeding elevator adopts a traditional dismounting structure, the protection plate is required to be dismounted manually during cleaning, and then is remounted after cleaning, the whole process is complex in operation and long in time consumption, the cleaning and maintaining efficiency is greatly reduced, secondly, the feeding elevator is high in equipment, operators need to ascend in height during cleaning operation, safety accidents such as falling easily occur during ascending, and the like, and great potential safety hazards exist, thirdly, the inner space of the feeding elevator is narrow, all sanitary dead corners are difficult to touch during manual cleaning, the cleaning difficulty is high, and the operation efficiency is low, so that thorough cleaning cannot be realized.
