[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] In the description of the present utility model, it should be understood that the terms "upper", "middle", "outer", "inner", "lower", etc. indicating the orientation or position relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0022] Please refer to Figure 1 、 Figure 2 In one embodiment, the present utility model provides a coal retaining wall hydraulically driven by a crawler base, which includes a crawler chassis 01 and a coal retaining wall assembly 02 disposed on the crawler chassis 01.

[0023] The coal retaining wall assembly 02 includes a support frame 21 and a coal retaining plate 22. The support frame 21 is fixedly disposed on the crawler chassis 01. The upper end of the coal retaining plate 22 is connected to the support frame 21, and the lower end of the coal retaining plate 22 extends downward toward the side away from the crawler chassis 01, so that the coal retaining plate 22 is inclined and disposed on one side of the crawler chassis 01. By adopting hydraulic drive for the crawler chassis 01, the coal retaining wall assembly 02 can be moved forward, backward, left and right. The coal retaining wall assembly 02 is inclined and disposed on the side close to the coal wall, and the guiding surface of the coal retaining wall assembly 02 extends to the lower side of the crawler chassis 01 side, ensuring that the fallen coal blocks or gangue can be quickly cleaned and preventing the crawler chassis 01 from getting stuck.

[0024] In one implementation manner, the length of the coal retaining plate 22 can be adjusted, so that the coverage area of the coal retaining plate 22 can be adjusted according to the actual use environment and the usage requirements.

[0025] Specifically, the coal retaining plate 22 includes a first plate body 221 and a second plate body 222. The first plate body 221 is inclined and disposed on one side of the support frame 21, and the second plate body 222 is slidably disposed on the first plate body 221, so that the second plate body 222 can slide along the first plate body 221 toward the lower side of the crawler chassis 01 side to adjust the overall length of the coal retaining plate 22.

[0026] Specifically, a first telescopic part 03 for controlling the sliding of the second plate body 222 is disposed below the first plate body 221. The fixed end of the first telescopic part 03 is hinged to the bottom of the first plate body 221, and the extending end of the first telescopic part 03 is hinged to the bottom of the second plate body 222. After the first telescopic part 03 extends, the second plate body 222 will slide out along the first plate body 221, and the overall length of the coal retaining plate 22 can be increased, thereby increasing the coverage area of the coal retaining plate 22. When not in use or when a large coverage area is not required, the first telescopic part 03 can be controlled to contract, and then the second plate body 222 is slid toward the first plate body 221 to achieve the adjustment purpose.

[0027] Specifically, guide grooves 223 capable of guiding the second plate body 222 are provided on both sides of the first plate body 221. At the same time, sliders adapted to the guide grooves 223 are provided on both sides of the second plate body 222, so that the sliders can slide along the guide grooves 223.

[0028] In an implementation manner, the upper end of the first plate body 221 is rotatably connected to the upper part of the support frame 21, and a second telescopic part 04 for controlling the inclination angle of the coal baffle 22 is provided on the support frame 21.

[0029] Specifically, the fixed end of the second telescopic part 04 is hinged to the support frame 21, and the extending end of the second telescopic part 04 is hinged to the first telescopic part 03. After the second telescopic part 04 extends, it can push the first telescopic part 03 and the coal baffle 22 as a whole to rotate upward, so that the angle between the coal baffle 22 and the horizontal direction can be reduced; after the second telescopic part 04 contracts, it can drive the first telescopic part 03 and the coal baffle 22 as a whole to rotate downward, so that the angle between the coal baffle 22 and the horizontal direction can be increased.

[0030] Under normal circumstances, the first telescopic part 03 and the second telescopic part 04 can adopt hydraulic cylinders; the first telescopic part 03 and the second telescopic part 04 can share a set of hydraulic systems with the crawler base.

[0031] In an embodiment, the present invention provides a coal mining conveyor, including the coal baffle wall hydraulically driven by the crawler base. The coal baffle wall is installed at the tail of the coal mining machine body and faces the side close to the coal wall at the tail.

[0032] The above-disclosed are only the preferred embodiments of the present invention. Of course, the scope of the rights of the present invention cannot be limited by this. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
