[0029] like Figure 1-5 As shown, the utility model is a double-row scraper conveyor chain, including a scraper body 7, an externally threaded rod 9 welded on the surface of the scraper body 7, an extension plate 8 is provided on the outside of the scraper body 7, a slide groove 10 is opened on the surface of the extension plate 8, the externally threaded rod 9 is located inside the slide groove 10, and by opening the slide groove 10, the slide groove 10 can be used to provide a movable effect for the extension plate 8, which is very convenient to use. A first nut 12 is installed on the surface of the externally threaded rod 9, and one end of the first nut 12 is attached to the surface of the extension plate 8. A limiting rod 11 is welded on the surface of the scraper body 7, and the limiting rod 11 is located inside the slide groove 10. By installing the limiting rod 11, in the process of moving the scraper body 7, the limiting rod 11 can be used to provide a limiting effect for the scraper body 7, so that the scraper body 7 will not have an angular deviation, and has strong stability during movement.

[0030] A second fixing plate 17 is welded on the surface of the scraper body 7, and a second side plate 6 is provided on the outside of the scraper body 7. A first fixing plate 13 is welded on the surface of the second side plate 6. The surface of the first fixing plate 13 is fitted on the second fixing plate 17. The bolt 14 is sleeved on the inside of the second fixing plate 17, and the bolt 14 passes through the first fixing plate 13. The second nut 21 is sleeved on the surface of the bolt 14, and one end of the second nut 21 is fitted on the first fixing plate 13. By installing the bolt 14 and the second nut 21, the bolt 14 and the second nut 21 are used to fix the scraper body 7 and the second side plate 6, so that the scraper body 7 has a replaceable effect. When the scraper needs to be replaced, the bolt 14 can be directly removed to replace the scraper, which is very convenient to use.

[0031] The second side panel 6 is internally sleeved with a fixing rod 4, one end of the fixing rod 4 is welded to the first side panel 1, the surface of the fixing rod 4 is sleeved with a sleeve 2, and the surface of the sleeve 2 is welded with a third side panel 3. The third side panel 3 is symmetrically distributed. By installing the fixing rod 4 and the sleeve 2 and using the sleeve 2 to sleeve the fixing rod 4, a rotatable effect can be provided for the first side panel 1 and the second side panel, so that the first side panel 1 and the second side panel 6 have an angle-changing effect, which is very convenient to use.

[0032] The surface of the bolt 14 is sleeved with a collar 15, and a limit block 16 is welded on the surface of the collar 15. The limit block 16 passes through the first fixed plate 13, and the limit block 16 passes through the second fixed plate 17. By installing the limit block 16 and utilizing the limit block 16 to pass through the first fixed plate 13 and the second fixed plate 17, the first fixed plate 13 and the second fixed plate 17 will not rotate around the bolt 14, and the stability is strong during use.

[0033] An external thread is provided on the surface of the fixing rod 4, and an internal thread cover 5 is sleeved on the surface of the fixing rod 4. One end of the internal thread cover 5 is fitted to the second side panel 6. By installing the internal thread cover 5, the fixing rod 4 can be fixed inside the sleeve 2 using the internal thread cover 5, thereby providing a fixing effect for the first side panel 1 and the second side panel 6, so that the first side panel 1 and the second side panel 6 will not disperse during use, and are more stable during use.

[0034] A second retaining ring 20 is welded on the surface of the external threaded rod 9, and the surface of the second retaining ring 20 is attached to the surface of the first nut 12.

By installing the second retaining ring 20, the second retaining ring 20 can provide a limiting effect for the first nut 12, so that the first nut 12 will not separate from the external threaded rod 9, which is very convenient to use.

[0035] The working principle of the double-row scraper conveyor chain: When using the double-row scraper conveyor chain, the fixing rod 4 on the side of the first side plate 1 should first be passed through the sleeve 2, and then passed through the second side plate 6, and finally the internal thread cover 5 should be installed on the surface of the fixing rod 4 until one end of the internal thread cover 5 is fitted to the second side plate 6, and then the first fixing plate 13 and the second fixing plate 17 are fitted to each other, and the bolt 14 is used to pass through the first fixing plate 13 and the second fixing plate 17 at the same time, and then the collar 15 is sleeved on the surface of the bolt 14, and the limit block 16 on the surface of the collar 15 is used to pass through the first fixing plate 13 and the second fixing plate 17, and finally the second nut 21 is sleeved on the surface of the bolt 14 to form the first fixing plate 13 and the second fixing plate 17 After fixing, you can use the double-row scraper conveyor chain. When using the scraper body 7 to transport materials, the slide 10 can be used to move the scraper body 7 outward. At this time, during the movement, the limit rod 11 can be used to provide a limiting effect for the scraper body 7, so that the scraper body 7 will not have an angular deviation. When the scraper body 7 moves to the appropriate position, rotate the first nut 12 to squeeze the extension plate 8 to fix the extension plate 8. At this time, the extension plate 8 is used to expand the area of ​​the scraper body 7, thereby increasing the contact area between the material and the scraper body 7, which improves the stability of material transportation during use. When the scraper needs to be replaced, the bolt 14 can be directly removed to replace the scraper, which is very convenient to use.
