Description

Technical Field

[0001] The utility model relates to the technical field of belt conveyor straight-line cleaners, in particular to a novel anti-jumping belt conveyor straight-line cleaner. Background Art

[0002] In the process of material transportation at the port, a straight-line cleaner is one of the indispensable equipment. It is installed on the belt conveyor to clean the materials on the belt in time, and it also protects the belt and the roller. The traditional straight-line cleaner is usually simply fixed on the steel structure of the belt conveyor, and the two ends of the straight-line cleaner are fixed using the existing belt frame. Since the belt will jump during operation, the straight-line cleaner will jump, making it impossible for the straight-line cleaner to fit the belt well, resulting in the inability of the straight-line cleaner to effectively clean the materials. The belt conveyor is prone to sticky materials during operation. If it cannot be cleaned in time, it will cause damage to the belt surface. In addition, the jumping of the straight-line cleaner also aggravates the wear of the cutter head, affecting its service life and failing to meet the use requirements. Based on the above, we propose a new type of anti-jumping belt conveyor straight-line cleaner. Utility Model Content
