[0023] Embodiment 1

[0024] Referring to Figure 1 , this embodiment provides a coal accumulation prevention device for a belt tensioning device, including a belt tensioning device main body 1, which includes at least two brackets 11.

[0025] Specifically, the two brackets 11 are symmetrically arranged, the two brackets 11 are jointly fixedly connected to the counterweight 12, the belt tensioning roller 13 is rotatably connected to the bracket 11, and the belt main body 14 is tensioned under the combined action of the counterweight 12, the belt tensioning roller 13 and the bracket 11. This is the prior art and will not be elaborated here;

At the same time, through the second coal accumulation prevention member 22, when coal falls onto the second coal accumulation prevention member 22, the self-gravity of the coal will cause the second coal accumulation prevention member 22 to rotate, further preventing coal accumulation between the belt main body 14 and the counterweight 12, effectively avoiding the increase in the weight of the counterweight 12 by coal, affecting the accuracy of belt tensioning, and thus avoiding the occurrence of fires and improving safety;

[0027] Example 2

[0028] Reference Figures 1 - 4 This embodiment is different from the first embodiment in that the first coal accumulation preventing member 21 includes a coal accumulation preventing partition 211 provided on the bracket 11, and the coal accumulation preventing partition 211 is provided with a first inclined surface 212 and a second inclined surface 213;

[0029] Specifically, the anti-coal accumulation partition 211 is located between the two brackets 11, and the two brackets 11 are fixedly connected to the anti-coal accumulation partition 211. The first inclined surface 212 and the second inclined surface 213 are provided with an anti-stick coating;

[0030] The first anti-coal accumulation member 21 further includes a through hole 214 provided on the bracket 11, and a third inclined surface 215 is provided in the through hole 214; the counterweight 12 is provided with a fourth inclined surface 121 and a fifth inclined surface 122;

[0031] Specifically, the third inclined surface 215, the fourth inclined surface 121 and the fifth inclined surface 122 are all provided with an anti-stick coating;

[0032] It should be noted that the anti-stick coating can be a polytetrafluoroethylene (PTFE) coating, a super-hydrophobic coating, etc., which can effectively prevent coal from sticking and can promote coal sliding. At the same time, an anti-stick coating can also be provided on all structures of the device to improve the effect of preventing coal from sticking;

[0033] When in use, in conjunction with Example 1, when coal falls onto the anti-coal accumulation partition 211, under the action of the first inclined surface 212 and the second inclined surface 213, the coal will slide along the first inclined surface 212 and the second inclined surface 213 to prevent the coal from accumulating on the anti-coal accumulation partition 211, and under the action of the anti-sticking coating on the first inclined surface 212 and the second inclined surface 213, when the coal falls onto the anti-coal accumulation partition 211, the coal will slide smoothly from the first inclined surface 212 and the second inclined surface 213. , and the coal will not stick to the anti-coal accumulation partition 211, further preventing the coal from accumulating on the anti-coal accumulation partition 211. At the same time, when some coal accidentally falls onto the counterweight 12, the third inclined surface 215, the fourth inclined surface 121, the fifth inclined surface 122, the through hole 214 and the anti-stick coating cooperate to make the coal slide down, preventing the coal from accumulating on the counterweight 12, effectively preventing the coal from increasing the weight of the counterweight 12 and affecting the accuracy of the belt tensioning, thus avoiding the occurrence of fire and improving safety;

[0034] Example 3

[0035] Reference Figures 1 - 3 This embodiment is different from the first embodiment in that the second anti-coal accumulation member 22 includes a rotating shaft 221 provided between the belt body 14 and the anti-coal accumulation partition 211, a rotating column 222 is provided on the rotating shaft 221, and a cleaning blade 223 is provided on the rotating column 222;

[0036] Specifically, the rotating shaft 221 is located between the two brackets 11, and the two brackets 11 are jointly rotatably connected to the rotating shaft 221. The outer surface of the rotating shaft 221 is fixedly connected to the rotating column 222. The rotating column 222 is arranged in a ring shape. A plurality of cleaning blades 223 are provided, and the plurality of cleaning blades 223 are distributed in a circular array. The cleaning blades 223 are arranged in an arc shape. When coal falls onto one of the cleaning blades 223, since the rotating shaft 221 is rotatably connected to the bracket 11, the cleaning blade 223 will drive the rotating column 222 and the rotating shaft 221 to deflect around the rotating shaft 221 under the self-gravity of the coal. This deflection will break the balance state of the rotating shaft 221 and the rotating column 222. At this time, the rotating shaft 221 drives the rotating column 222 and the cleaning blade 223 to rotate independently;

[0037] A guiding piece 2231 is provided on the cleaning blade 223, and a first guiding surface 2232 is provided on the guiding piece 2231;

[0038] Specifically, the guiding piece 2231 is fixedly connected to the cleaning blade 223, and an anti-sticking coating is provided on the first guiding surface 2232;

[0039] The guiding part 3 includes a first guiding plate 31 provided between the cleaning blade 223 and the belt main body 14, and two second guiding plates 32 are provided on the first guiding plate 31;

[0040] Specifically, the first guiding plate 31 is located between the two brackets 11, and the two brackets 11 are jointly fixedly connected to the first guiding plate 31. The two second guiding plates 32 are fixedly connected to the first guiding plate 31. The two second guiding plates 32 are symmetrically arranged. The two second guiding plates 32 are respectively fixedly connected to the two brackets 11. The first guiding plate 31 and the two second guiding plates 32 are both arranged in an inclined plane to effectively divert the coal onto one of the cleaning blades 223;

[0041] During use, in conjunction with Embodiment 1, through the first guiding plate 31 and the two second guiding plates 32, the coal falls onto the corresponding cleaning blade 223 through the first guiding plate 31 and the two second guiding plates 32. Since the rotating shaft 221 is rotatably connected to the bracket 11, the cleaning blade 223 will drive the rotating column 222 and the rotating shaft 221 to deflect around the rotating shaft 221 under the self-gravity of the coal. This deflection will break the balance state of the rotating shaft 221 and the rotating column 222. At this time, the rotating shaft 221 drives the rotating column 222 and the cleaning blade 223 to rotate independently. When rotating, the coal will slide off the cleaning blade 223, effectively preventing the coal from accumulating between the belt main body 14 and the counterweight 12. When the coal falls from the right side of the first guiding plate 31, it will contact the corresponding guiding piece and will not fall onto the cleaning blade 223, so that it slides off under the action of the guiding piece, the first guiding surface 2232 and the anti-sticking coating, avoiding the situation where the coal falls onto the two cleaning blades 223 and the rotating shaft 221 and the rotating column 222 are in a balanced state and cannot rotate independently;

[0042] In conjunction with Embodiment 2, the cooperation between the cleaning blade 223 and the anti-coal-accumulation partition 211 further prevents coal from accumulating between the belt main body 14 and the counterweight 12, improves the anti-coal-accumulation effect, thereby avoiding the occurrence of fires and enhancing safety;

An extension block 37 is provided on the lower side of the guiding seat 33, and a fourth guiding inclined surface 38 is provided on the extension block 37;

[0045] Specifically, the guiding seat 33 is located between the two brackets 11, and the two brackets 11 are fixedly connected to the guiding seat 33.

[0047] Specifically, an anti-sticking coating is provided on the third guiding surface 332. There are two third guiding plates 331, and the two third guiding plates 331 are symmetrically arranged.

Through the cooperation of the extension block 37, the fourth guiding inclined surface 38, the guiding block 2233, and the second guiding surface 2234, an extension guiding effect is achieved, enabling the coal to all fall on the corresponding cleaning blade 223, allowing the cleaning blade 223 to better drive the rotating column 222 and the rotating shaft 221 to rotate independently, preventing the coal from accumulating between the belt main body 14 and the counterweight 12. At the same time, through the two third guiding plates 331, it effectively avoids the coal from directly falling on the cleaning blade 223.
