[0002] During coal mining, belt conveyors are often used to transport coal. Since coal slime often adheres to the belts of belt conveyors, not only does the belt bear a heavy load, but the belt conveyors used in mines are often also equipped with a belt press roller. If coal slime adheres to the belt, it is very easy for the outer surface of the belt press roller to adhere to the coal slime, causing the outer diameter of the belt press roller to increase, affecting the tension of the belt, and the coal slime adhered to the belt is brought into the belt storage bin, affecting normal use.

[0003] In the related art, a coal sweeping device is provided, and during the belt conveying process, a coal sweeping plate of the coal sweeping device is slidably matched with the belt, so that the coal sweeping device is used to clean the coal slime adhering to the belt.

[0004] However, the coal sweeping device in the related art is fixed relative to the belt conveyor. As the coal mining face advances, the straightness of the belt of the belt conveyor changes during continuous dismantling and mobilization operations, and the coal sweeping device cannot move with the belt, making the coal sweeping device easy to be damaged. In addition, the coal sweeping gap between the coal sweeping plate of the coal sweeping device and the belt cannot be adjusted to meet the coal sweeping needs when the belt is concave.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1 As shown, an embodiment of the utility model provides a coal sweeping device, which includes a mounting seat 10, a coal sweeping member 20 and an arc-shaped guide structure 30. The coal sweeping member 20 is rotatably arranged on the mounting seat 10, and the coal sweeping member 20 extends laterally relative to the rotation axis of the mounting seat 10. The arc-shaped guide structure 30 is arranged between the coal sweeping member 20 and the mounting seat 10. The arc-shaped guide structure 30 is an arc-shaped structure extending around the rotation axis to guide the coal sweeping member 20 to rotate when the coal sweeping member 20 rotates relative to the mounting seat 10.

[0026] By applying the technical solution of the utility model, the coal sweeping device includes a mounting seat 10, a coal sweeping piece 20 and an arc-shaped guide structure 30. The mounting seat 10 is mounted on the belt conveyor, and the coal sweeping piece 20 slides with the belt to clean the coal slime adhered to the belt. Since the coal sweeping piece 20 is rotatably arranged on the mounting seat 10, when the belt of the belt conveyor changes in straightness during continuous dismantling and mobilization operations, the coal sweeper rotates relative to the mounting seat 10 as the straightness of the belt changes under the action of the force applied by the belt to the coal sweeping piece 20 and the gravity of the coal sweeping piece 20 itself, so that the coal sweeper rotates relative to the mounting seat 10 as the straightness of the belt changes, so that the coal sweeping piece 20 can adaptively rotate according to the shape of the belt to avoid damage to the coal sweeping device, and the coal sweeping gap between the coal sweeping plate and the belt can change as the straightness of the belt changes to meet the coal sweeping needs of the belt after the straightness change. In addition, by utilizing the arc-shaped guide structure 30 disposed between the coal sweeper 20 and the mounting seat 10, when the coal sweeper rotates relative to the mounting seat 10, the rotation of the coal sweeper 20 can be guided to prevent the coal sweeper 20 from escaping from the cleaning range of the belt.

[0027] It should be noted that horizontal refers to Figure 1 The X direction marked in .

[0028] In this embodiment, the coal sweeping member 20 is hinged to the mounting seat 10, and the hinged portion of the coal sweeping member 20 and the mounting seat 10 is located on the rotation axis. By hingedly connecting the coal sweeping member 20 and the mounting seat 10, a stable rotation axis can be provided for the rotation of the coal sweeping member 20 relative to the mounting seat 10.

With the above structure, the bracket 21 and the coal sweeping plate 22 can be made of different materials according to their respective use requirements, thereby reducing costs, and the coal sweeping plate 22 with a plate-like structure can also improve the cleaning effect of the coal slime adhered to the belt.

[0033] like Figure 1 As shown, the coal sweeping plate 22 is arranged at an angle with the rotation axis.

[0034] like Figure 1 As shown, the bracket 21 includes a main beam 211, a support plate 212 and a vertical plate 213. The main beam 211 is rotatably arranged on the mounting seat 10 and extends in the transverse direction. The support plate 212 is arranged on a side of the main beam 211 away from the mounting seat 10. The coal sweeping plate 22 is arranged on a side of the support plate 212 away from the main beam 211. One end of the support plate 212 in the transverse direction is connected to the main beam 211. The other end of the support plate 212 in the transverse direction is inclined in a direction away from the main beam 211. The vertical plate 213 is arranged on a side of the main beam 211 away from the mounting seat 10. One end of the vertical plate 213 away from the main beam 211 extends to the support plate 212 and is connected to the support plate 212. The vertical plate 213 is arranged between the support plate 212 and the main beam 211, which can play an auxiliary supporting effect on the support plate 212 and make the structure of the bracket 21 simple and easy to process.

[0035] like Figure 1 As shown, the side of the bracket 21 facing the mounting seat 10 has a first connecting ear 214, the side of the mounting seat 10 facing the bracket 21 has a second connecting ear 11, and the arc-shaped guide structure 30 is arranged between the first connecting ear 214 and the second connecting ear 11.
