[0016] Figure 1 is a schematic structural view of an idler of an unloading station according to an embodiment of the present utility model;

[0017] Figure 2 is a cross-sectional view of an idler of an unloading station according to an embodiment of the present utility model;

[0018] Figure 3 Yes Figure 2 An enlarged view of area A in Specific implementation mode

[0019] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.

[0020] The idler 100 of the unloading station according to an embodiment of the present utility model will be described below with reference to the accompanying drawings. As Figures 1 - 3 shown, the idler 100 of the unloading station according to an embodiment of the present utility model includes a shaft 1, a bearing 2, a carrier roller 3, a first seal 4 and a particulate seal 5.

[0021] The bearing 2 is sleeved on the shaft 1, and the carrier roller 3 is sleeved on the bearing 2. When the mine car is unloaded at the unloading station, the mine car contacts the carrier roller 3 so that the carrier roller 3 rotates while the shaft 1 does not rotate. The first seal 4 is arranged between the shaft 1 and the carrier roller 3. The particulate seal 5 is arranged between the shaft 1 and the carrier roller 3, and the first seal 4 is axially located between the bearing 2 and the particulate seal 5 on the shaft 1.

[0022] By providing the particulate seal 5, the idler 100 of the unloading station according to an embodiment of the present utility model can intercept impurities such as particles and dust by using the particulate seal 5, so as to avoid the attachment of impurities to the first seal 4 and further wear the first seal 4. Thereby, not only the service life of the first seal 4 can be improved, and then the service life of the idler 100 can be improved, but also the lubricating oil in the idler 100 can be further prevented from being oxidized and the bearing 2 from being worn, so as to extend the running time of the idler 100 and reduce the maintenance times and maintenance costs of the idler 100.

[0023] Therefore, the idler 100 of the unloading station according to an embodiment of the present utility model has the advantages of long service life, few maintenance times, low maintenance cost, long running time, etc. The maintenance-free life of the idler of the existing unloading station is only two years, and the maintenance-free life of the idler 100 of the unloading station of the present utility model can reach 5 years.

[0024] As Figures 1 - 3 shown, the idler 100 of the unloading station according to an embodiment of the present utility model includes a shaft 1, a bearing 2, a carrier roller 3, a first seal 4 and a particulate seal 5. The first seal 4 may be a skeleton oil seal, and the particulate seal 5 may be one of a polytetrafluoroethylene dust-proof ring and a polyurethane dust-proof ring.

[0025] The shaft 1 may be installed on the bracket 6. As Figure 1 and Figure 2As shown, the bracket 6 includes a bottom plate 71, a first mounting plate 72 and a second mounting plate 73. The bottom plate 71 is provided on the body of the unloading station. The first mounting plate 72 and the second mounting plate 73 are provided on the bottom plate 71 at intervals along the axial direction of the shaft 1. The shaft 1 is provided on the first mounting plate 72 and the second mounting plate 73. The axial direction of the shaft 1 is as Figure 2 shown by the arrow B in

[0026] The shaft 1 includes a shaft body 11 and a spacer 12. The spacer 12 is sleeved on the shaft body 11. The bearing 2 is sleeved on the shaft body 11. By providing the spacer 12, the service life of the shaft 1 can be extended. Optionally, the shaft body 11 is provided with a shaft shoulder, the spacer 12 abuts against the shaft shoulder, and the bearing 2 abuts against the spacer 12.

[0027] As Figure 3 shown, the idler wheel 3 includes a wheel body 31 and a bracket 32. The wheel body 31 is sleeved on the bearing 2. The bracket 32 is connected to the wheel body 31 so that the wheel body 31 and the bracket 32 rotate together. Among them, there is a chamber capable of accommodating lubricating oil between the shaft 1, the bearing 2 and the idler wheel 3. The first seal 4 is used to seal this chamber to prevent the lubricating oil from being oxidized. If the particle seal 5 is not provided, the first seal 4 will be worn by impurities, resulting in the first seal 4 being unable to seal this chamber, thereby causing the lubricating oil to be oxidized.

[0028] Each of the first seal 4 and the particle seal 5 is provided between the bracket 32 and the spacer 12. Each of the first seal 4 and the particle seal 5 is connected to the bracket 32 so as to rotate under the drive of the bracket 32. Thereby, the structure of the idler 100 can be made more reasonable.

[0029] For example, the outer end of each of the first seal 4 and the particle seal 5 is connected to the bracket 32, and the inner end of each of the first seal 4 and the particle seal 5 abuts against the spacer 12 on the shaft 1.

[0030] As Figure 3 shown, the particle seal 5 includes a straight section 51 and a bent section 52. The outer end of the straight section 51 is connected to the bracket 32 of the idler wheel 3. The outer end of the bent section 52 is connected to the inner end of the straight section 51, and the inner end of the bent section 52 abuts against the spacer 12 on the shaft 1.

[0031] By providing the bending section 52, the particulate seal 5 can be brought into closer contact with the spacer ring 12, so that the particulate seal 5 can more effectively intercept impurities such as particles and dust, thereby further preventing the impurities from wearing the first seal 4. As a result, not only can the service lives of the first seal 4, the bearing 2, and the idler 100 be further extended, but also the maintenance frequency and maintenance cost of the idler 100 can be further reduced, and the running time of the idler 100 can be further prolonged. Wear of the first seal 4 can cause the lubricating oil inside the idler 100 to be oxidized. When new lubricating oil is manually injected, impurities such as particles and dust will enter the bearing 2 along with the lubricating oil, greatly affecting the life of the bearing 2.

[0032] As Figure 3 shown, the bracket 32 includes a frame body 321 and a first spacer ring 322, and the frame body 321 is connected to the wheel body 31. Each of the first seal 4 and the particulate seal 5 is disposed between the shaft 1 and the frame body 321. The outer end of the first spacer ring 322 is connected to the frame body 321, and the inner end of the first spacer ring 322 is adjacent to the shaft 1 or the inner end of the first spacer ring 322 abuts against the shaft 1. The particulate seal 5 is axially located between the first seal 4 and the first spacer ring 322 on the shaft 1. The first spacer ring 322 is provided with a receiving groove 323, and at least a part of the bending section 52 is located in the receiving groove 323.

[0033] This can make the structure of the idler 100 more compact and reasonable. Moreover, the first spacer ring 322 can intercept a part of impurities such as particles and dust, so that not only can the service lives of the first seal 4, the bearing 2, and the idler 100 be further extended, but also the maintenance frequency and maintenance cost of the idler 100 can be further reduced, and the running time of the idler 100 can be further prolonged.

[0034] Optionally, the particulate seal 5 abuts against each of the first seal 4 and the first spacer ring 322. This can further improve the sealing effect of the particulate seal 5, so that the particulate seal 5 can more effectively intercept impurities such as particles and dust, so that not only can the service lives of the first seal 4, the bearing 2, and the idler 100 be further extended, but also the maintenance frequency and maintenance cost of the idler 100 can be further reduced, and the running time of the idler 100 can be further prolonged.

[0035] As Figure 3 shown, the idler 100 of the unloading station further includes a second seal 6, and the second seal 6 is disposed between the bracket 32 and the spacer ring 12. For example, the second seal 6 is disposed between the frame body 321 and the ring body 121 of the spacer ring 12. The second seal 6 has a particulate receiving cavity, and the particulate seal 5 is axially located between the first seal 4 and the second seal 6 on the shaft 1.

[0036] Thus, the second seal 6 can intercept impurities such as particles and dust, so as to further prevent impurities from adhering to the first seal 4 and further wearing the first seal 4. Thereby, not only the service life of the first seal 4, the bearing 2 and the idler 100 can be further improved, but also the maintenance frequency and maintenance cost of the idler 100 can be further reduced, and the running time of the idler 100 can be further extended.

[0037] Optionally, the second seal 6 is a flocked seal.

[0038] As Figure 3 shown, the spacer ring 12 includes a ring body 121 and a second spacer ring 122. The ring body 121 is sleeved on the shaft body 11. The inner end of the first spacer ring 322 is adjacent to the ring body 121 or the inner end of the first spacer ring 322 abuts against the ring body 121. The inner end of the second spacer ring 122 is connected to the ring body 121, and the outer end of the second spacer ring 122 is adjacent to the frame body 321 or the outer end of the second spacer ring 122 abuts against the frame body 321. The particle seal 5 is axially located between the first seal 4 and each of the first spacer ring 322 and the second spacer ring 122 on the shaft 1.

[0039] Thereby, the structure of the idler 100 can be made more reasonable. The second spacer ring 122 can intercept a part of impurities such as particles and dust, so that not only the service life of the first seal 4, the bearing 2 and the idler 100 can be further improved, but also the maintenance frequency and maintenance cost of the idler 100 can be further reduced, and the running time of the idler 100 can be further extended.

[0040] As Figure 3 shown, the first spacer ring 322 and the second spacer ring 122 are axially spaced along the shaft 1, and the second seal 6 is axially located between the first spacer ring 322 and the second spacer ring 122 on the shaft 1. Thereby, the second seal 6 can be installed more stably, making the structure of the idler 100 more compact and more reasonable. Moreover, the first spacer ring 322 and the second spacer ring 122 can intercept a part of impurities such as particles and dust, so that not only the service life of the first seal 4, the bearing 2 and the idler 100 can be further improved, but also the maintenance frequency and maintenance cost of the idler 100 can be further reduced, and the running time of the idler 100 can be further extended.

[0041] Optionally, the second seal 6 abuts against each of the first spacer ring 322 and the second spacer ring 122. Thereby, the sealing effect of the second seal 6 can be further improved, so that the second seal 6 can more effectively intercept impurities such as particles and dust, so that not only the service life of the first seal 4, the bearing 2 and the idler 100 can be further improved, but also the maintenance frequency and maintenance cost of the idler 100 can be further reduced, and the running time of the idler 100 can be further extended.

[0042] AsFigure 3 As shown, each of the first seal 4, the particle seal 5, and the second seal 6 is provided between the ring body 121 and the frame body 321. The first seal 4, the particle seal 5, the first spacer ring 322, the second seal 6, and the second spacer ring 122 are arranged in sequence along the axial direction of the shaft 1.

[0043] Those skilled in the art can understand that the idler 100 may further include a static seal. This static seal can be known and has nothing to do with the novel points of the present application, so it will not be described in detail.

[0044] The unloading station of the present utility model includes a station body and an idler 100, and the idler 100 is provided on the station body.
