Description

Technical Field

[0001] The invention belongs to the technical field of feed production equipment, and in particular relates to a screen cleaner for automatically cleaning a vibrating screen. Background Art

[0002] Screens are different from ordinary mesh products. They have a strict series of mesh sizes. They are recognized by industries, organizations, and standards for grading and screening particles. Screens don't use a "mesh number"; the term "mesh number" is a common, yet difficult, way to describe them. Screens differ from ordinary mesh products in that they have a strict mesh size, not a "mesh number." Screen sizes aren't isolated; they consist of a series of mesh sizes, designed to provide grading and screening.

[0003] During the use of the vibrating screen, due to the long-term screening of feed, it is easy for residual feed to adhere to the screen, causing the screen to be blocked and the screening efficiency to be reduced. However, manual cleaning of the screen is not only inefficient but also has high labor costs. Summary of the Invention
