The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0023] The conveyor cleaning device 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0024] like Figure 1-Figure 2 As shown, the conveyor cleaning device 100 of the embodiment of the utility model includes a bracket 1 and a scraper 2.

[0025] The bracket 1 includes a frame body 11, and the frame body 11 is suitable for being arranged above the bottom belt 201. The scraper 2 includes a first end 21 and a second end 22 opposite to each other in the up-down direction, the first end 21 is located above the second end 22, the first end 21 is connected to the frame body 11, and the first end 21 is connected to the frame body 11, and the second end 22 is located below the frame body 11 so that the second end 22 cleans the bottom belt 201.

[0026] The specific implementation of the conveyor cleaning device 100 of the present invention will be described below with reference to the accompanying drawings.

[0027] The frame 11 is set above the bottom belt 201 of the conveyor 200. When gangue or coal blocks are attached to the bottom belt 201, the scraper 2 set on the frame 11 scrapes off the gangue or coal blocks attached to the bottom belt 201 to prevent the gangue or coal blocks from being drawn into the roller of the conveyor 200.

[0028] The conveyor cleaning device 100 of the utility model is provided with a scraper 2 above the bottom belt 201 of the conveyor 200, and the scraper 2 is used to scrape off the gangue or coal blocks attached to the bottom belt 201, thereby preventing the gangue or coal blocks from being rolled into the roller of the conveyor 200. Therefore, the conveyor cleaning device 100 of the utility model can clean the bottom belt 201 and avoid the failure of the conveyor 200.

[0029] In order to make the present application easier to understand, the following takes the horizontal direction and the front-back direction as an example to further describe the conveyor cleaning device 100 of the present utility model. Figure 1 As shown, the front-to-back direction is perpendicular to the up-down direction and the left-to-right direction.

[0030] In some embodiments, Figure 1As shown, the scraper 2 is tilted in the front-to-back direction. In other words, the scraper 2 forms a certain angle with the front-to-back direction, so that when the scraper 2 scrapes the gangue or coal blocks on the bottom belt 201, it is convenient to discharge the gangue or coal blocks from the front or rear of the scraper 2, thereby improving the practicality of the conveyor cleaning device 100 of the utility model.

[0031] In some embodiments, Figure 1 As shown, the scraper 2 includes a body 23 and a rotating shaft 24, the lower end of the rotating shaft 24 is connected to the body 23, the upper end of the rotating shaft 24 is rotatably connected to the frame 11, and the lower end of the body 23 forms a second end 22. In other words, the scraper 2 is rotatable relative to the frame 11, so that the scraper 2 can be rotated according to different working conditions to adjust its tilt angle, thereby further improving the practicality of the conveyor cleaning device 100 of the utility model.

[0032] In some embodiments, Figure 2 As shown, the frame 11 includes a first through hole 111, and the first through hole 111 is arc-shaped. The scraper 2 also includes a guide member 25 and a fixing member 26. The upper end of the guide member 25 is inserted into the through hole, and the guide member 25 can slide along the extension direction of the first through hole 111. The outer peripheral surface of the guide member 25 is provided with a first external thread, and the fixing member 26 includes a second through hole, and the inner wall surface of the second through hole is provided with a first internal thread that matches the first external thread, so that the fixing member 26 can match with the guide member 25.

[0033] After adjusting the inclination angle of the scraper 2, the fixing member 26 is matched with the guide member 25 to press the scraper 2 against the frame 11, which can not only prevent the scraper 2 from changing its inclination angle due to external force, but also provide support for the main body 23, making the connection between the main body 23 and the frame 11 more stable.

[0034] In some embodiments, Figure 2 As shown, the bracket 1 further includes: a support rod 12, and there are multiple support rods 12, each of which is movably connected to the frame body 11 in the up-down direction. In other words, the frame body 11 can move in the up-down direction relative to the support rod 12. Therefore, by changing the relative position of the frame body 11 and the support rod 12, the spacing distance between the lower end of the body 23 and the bottom belt 201 can be adjusted, ensuring that the body 23 can be cleaned without contacting the bottom belt 201, thereby avoiding damage to the bottom belt 201.

[0035] Specifically, each support rod 12 further includes: a rod body 121 and a support member 122, the support member 122 includes a third through hole, the inner wall surface of the third through hole is provided with a second internal thread, the rod body 121 is inserted into the third through hole, and the outer peripheral surface of the rod body 121 is provided with a second external thread matching the second internal thread. The frame body 11 is provided with a plurality of fourth through holes, the rod bodies 121 are inserted into the fourth through holes in a one-to-one correspondence, and each support member 122 is in contact with the frame body 11 to support the frame body 11. Thus, not only can the frame body 11 be able to move in the up and down direction relative to the support rod 12, but also the structure is simple and easy to manufacture.

[0036] Optionally, the size of the rod body 121 in the vertical direction is 60mm-90mm. Optionally, the size of the rod body 121 in the vertical direction is 67mm-84mm. Optionally, the size of the rod body 121 in the vertical direction is 73mm-78mm. This not only ensures that the rod body 121 has a sufficient length and that the main body 23 can be arranged above the bottom belt 201, but also avoids the problem of structural redundancy caused by the rod body 121 being too long.

[0037] The dimensions of the rod body 121 in the up and down directions include but are not limited to 60 mm, 62 mm, 67 mm, 70 mm, 72 mm, 82 mm, 87 mm or 90 mm.
