[0030] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0031] Please refer to Figures 1 to 5 A tooth scraping structure of a scraper includes a scraper chain 1, including:

[0032] The first flange 2 is connected to the scraper chains 1 on both sides;

[0033] The scraping roller 3 is connected between the two first flanges 2. The scraping roller 3 is a hollow shaft. Limiting openings 31 are provided on the scraping roller 3 at equal intervals along its axial direction. Threaded holes 32 are provided at both ends of the scraping roller 3.

[0034] The scraping plate 4 is in the shape of an L-shaped plate, one end of the L-shaped plate is a long scraping plate 4, and the other end of the L-shaped plate is an end scraping plate 4. A semi-arc groove 41 matching the scraping roller 3 is provided at the connection between the long scraping plate 4 and the short scraping plate 4. A protrusion 411 matching the limiting opening 31 is provided in the semi-arc groove 41. A first through hole 4111 is provided on the protrusion 411. The axial direction of the first through hole 4111 is parallel to the scraping roller 3.

[0035] The second flange 5 is provided with a second through hole 51 and a third through hole 52. Screws pass through the second through hole 51 and the threaded hole 32 in sequence to fix the second flange 5 to both ends of the scraper roller 3.

[0036] The limiting rod 6 has a radius smaller than that of the third through hole 52 and the first through hole 4111 , and external threads 61 are provided at both ends of the limiting rod 6 ;

[0037] The limiting cap 7 is provided with an internal thread matching the external thread 61 of the limiting rod 6;

[0038] During assembly, the protrusion 411 of the scraping plate 4 is inserted into the limiting opening 31, so that the first through hole 4111 of the protrusion 411 is located in the scraping roller 3, and the limiting rod 6 is passed through the first through hole 4111 and the third through hole 52. The internal thread of the limiting cap 7 matches the external thread 61 at both ends of the limiting rod 6, so that the limiting cap 7 rests on the second flange 5.

[0039] In the above embodiment, when the scraper plate 4 needs to be disassembled, the screw is first disengaged from the threaded hole 32 and the second through hole 51, and then the limiting cap 7 is disengaged from the external thread 61 of the limiting rod 6, and then the limiting rod 6 is pulled out from the first through hole 4111 of the protrusion 411 of the scraper plate 4 and the third through hole 52 of the second flange 5, and the scraper plate 4 can be disassembled. The entire scraper plate 4 can be replaced, and the partially damaged scraper plate 4 can also be replaced. Compared with the existing technology, the structure is simple, the scraper plate 4 is easy to replace, and the maintenance cost is reduced.

[0040] As an optional implementation, the first flange 2 is integrally welded to the chain.

[0041] In the above embodiment, the integrated welding connection method is more stable and efficient.

[0042] As an optional implementation, the second flange 5 is in the shape of a rectangular piece.

[0043] As an optional implementation, the limiting opening 31 is in the shape of a strip-shaped opening.

[0044] In the above embodiment, a strip-shaped opening is provided, which can better allow the protrusion 411 for scraping to be inserted.

[0045] As an optional implementation, the spacing between the limiting openings 31 is 1-5 cm.

[0046] In the above implementation manner, the iron slag in the molten iron can be better trapped.

[0047] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention.
