[0002] At present, my country's coal mining industry generally uses heavy medium shallow trough separators to separate and sort coal gangue. Its main components include trough body, chain track and wear-resistant lining. The front end trough track often faces the following problems during use due to structural design defects and working environment: Since the front end trough body has a certain upward tilt angle, the interaction force between the trough body and the chain is increased. At the same time, there is almost dry friction between the two, and there is no friction reduction measure, which leads to serious wear and loss between the two. The severe wear and tear seriously shortens the life cycle of the equipment, which in turn causes the factory to frequently shut down to replace equipment, seriously reducing production efficiency and greatly increasing equipment maintenance costs.

[0003] Therefore, in order to solve the above problems, the utility model provides a rolling body structure applied to the front end arc slideway of a heavy medium shallow trough separator. Utility Model Content

DETAILED DESCRIPTION

[0028] The specific implementation of a rolling body structure applied to the front end arc-shaped slideway of a heavy medium shallow trough separator provided by the present invention is further described in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1-4 As shown, a rolling element structure for use in the front-end curved slideway of a heavy medium shallow trough separator is used for installation at the curved corner of the front end of the side plate slideway of the heavy medium shallow trough separator. The rolling element structure comprises a main body 3 of the rolling element structure, which includes a curved slideway 31, several rolling assemblies, a front cover 33, and a rear cover 34. The curved slideway 31 is provided with at least four mounting holes 32 arranged side by side; each mounting hole 32 is provided with a rolling assembly. Preferably, the front cover 33 and the rear cover 34 are fixed to the side walls of the curved slideway 31 by screws, which not only limit the rolling assembly but also prevent foreign matter from entering and causing the rolling assembly to jam.

[0030] like Figure 5-6 As shown, the rolling assembly includes a rolling element 35, two sealed bearings 36 and a fixed roller 37;

[0031] like Figure 9 As shown, the rolling element 35 includes a roller 352 and a fixed shaft 353, wherein the two sealed bearings 36 are respectively sleeved on the front and rear sides of the roller 352. Preferably, the selected model of the sealed bearing 36 is 6211-2RS1, which has good sealing performance. The fixed roller 37 is fixedly sleeved on the fixed shaft 353 and a pin hole 351 is opened on the side of the fixed shaft 353 close to the front cover 33. The inner side wall of the front cover 33 is provided with an axis pin 331 (as shown in FIG. 1 ) at a position corresponding to the pin hole 351. Figure 7As shown), the rolling element 35 and the front end cover 33 achieve relative rotation by inserting the shaft pin 331 into the pin hole 351.

[0032] like Figure 8 As shown, an annular gasket 341 is provided on the inner side wall of the rear end cover 34 , and the annular gasket 341 abuts against the sealed bearing 36 located at the rear side of the roller 352 to achieve position limiting fixation.

[0033] Preferably, the arc-shaped slide 31 is provided with a through groove corresponding to the position of the bottom of the roller 352 and the fixed roller 37, so that the bottom of the roller 352 and the fixed roller 37 pass through the through groove and are in contact and connected with the chain 4 of the heavy medium shallow trough separator, thereby replacing the traditional sliding friction and changing the arc-shaped slide 31 subjected to a larger force and the chain 4 to rolling friction, thereby reducing the wear of components during operation.

[0034] It is worth noting that the annular gasket 341 provided on the inner wall of the rear end cover 34 not only seals and fixes the rolling assembly, but also creates a gap between the end of the rolling element 35 away from the front end cover 33 and the rear end cover 34, thereby avoiding affecting the normal rotation of the rolling element 35.

[0035] When the rolling element 35 rotates, it drives the fixed roller 37 to rotate together with it, and the rolling element 35 and the bearing rotate relative to each other, thereby achieving a rolling connection between the rolling assembly and the chain 4 without wearing the inner wall of the arc-shaped slideway 31.

[0036] Further preferably, the number of the mounting holes 32 can be set according to the actual size of the arc-shaped slideway 31 .

[0037] It is worth noting that the outer diameter of the roller 352 is the same as that of the fixed roller 37; the outer diameter of the annular gasket 341 is the same as that of the sealed bearing 36; the inner dimension of the mounting hole 32 is adapted to the outer dimension of the rolling assembly to ensure that the normal rotation of the rolling element 35 and the fixed roller 37 inside it is not affected.

[0038] The utility model converts the sliding friction between the original curved slideway and the chain into rolling friction by arranging bearings and rolling elements in the curved slideway, thereby effectively reducing wear during operation and extending the service life of the equipment; on the one hand, it reduces the number of replacements of easily worn parts, reduces the cost of consumables, and reduces the labor workload of workers; on the other hand, it also reduces safety hazards in production and improves the stability of equipment operation.
