[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] In the tobacco industry, the vibrating conveyor is an indispensable conveying device in the silk-making equipment. Its eccentric assembly (also known as the bearing seat) will wear out after working for a long time, affecting the normal operation of the equipment. The eccentric assembly needs to be disassembled for maintenance or replacement. The silk-making equipment includes multiple vibrating conveyors, which are located at different heights and are inconvenient to repair and replace. For the vibrating conveyors at lower positions, the distance between the eccentric assembly and the ground is limited, and the space left for maintenance personnel to carry out maintenance work is very narrow; while for the vibrating conveyors at higher positions, the distance between the eccentric assembly and the ground is too large, and there is a lack of a suitable load-bearing platform under the eccentric assembly. The eccentric assembly is installed upside down and has a large weight. Therefore, when installing or disassembling the eccentric assembly, four or five maintenance personnel are usually required to use straps to simultaneously exert force on both sides of the vibrating conveyor to pull up the eccentric assembly for disassembly and assembly. The disassembly and assembly process is time-consuming and labor-intensive and has safety hazards. Utility Model Content
