[0021] This device is installed at the bottom of the conveyor belt for stubble removal, providing support for the conveyor belt. The installation dimensions and angles of the idlers meet the working requirements of the conveyor belt. The idlers themselves run smoothly and without noise. Through reasonable distribution, they ensure their own supporting effect and improve the operating efficiency of the conveyor belt equipment.
[0022] The device is installed inside the frame of the conveyor equipment. The surface of the idler roller contacts the conveyor belt in a line or narrow area, and continuously provides a certain support force during the operation of the conveyor belt to reduce the deformation of the conveyor belt surface.
[0023] The device consists of an outer sleeve for the idler roller, the idler roller body, an inner liner strip, an inner shaft, bearings, a positioning sleeve, and positioning blocks. The positioning blocks ensure the stability of the idler roller assembly during installation, and the idler roller operates in a horizontal axial position.
[0024] This device can meet the needs of different working scenarios of the idler roller by changing the diameter of the outer surface of the idler roller, and can effectively adjust the change of the support force of the idler roller without changing the installation reference.
[0025] The device has corresponding positioning holes on the outer sleeve and the roller body structure. The outer sleeve and the roller body are fitted with a clearance to meet the quick change requirements of the outer sleeve and facilitate the quick replacement of roller bodies with different outer diameters.
[0026] The device's inner liner is installed in the guide groove inside the idler roller body, and its axial positioning between the idler roller outer sleeve, the idler roller body, and the drive bearing is achieved by using the protrusions on its own structure.
[0027] The device's inner shaft features a stepless design, facilitating installation and maintenance. Relevant positioning requirements are achieved through the cooperation of other related parts.
[0028] The outer sleeve of the idler roller is made of non-metallic material to reduce surface wear and operating noise, while most of the other parts are made of stainless steel to meet the working requirements in humid environments.
[0029] The main body of the device adopts a stepless design, which enables quick disassembly during the maintenance process and facilitates maintenance work on bearings in a rusted and disassembled state in a humid working environment.
