The tooth row group 4 is composed of a plurality of tooth rows, and an insert block 11 is welded on the outer surface of each tooth row, and the tooth row is inserted in the slot 10 through the insert block 11 for sliding sealing.
[0026] The diameters of the ring body 2 and the cover plate 3 are the same, and the outer surfaces of the tooth row group 4 and the ring body 2 are on the same horizontal plane after installation.
[0027] There are nineteen groups of gears in the gear row group 4.
[0028] By adopting the above technical solution, after the gear has worked for a long time, the tooth head is worn, resulting in a decrease in the performance of the gear row. When the gear needs to be replaced, firstly, the first nut 9 is rotated by a screwdriver to remove the first nut 9 from the first threaded hole 7 and the second threaded hole 8, and then the cover plate 3 is removed to separate the positioning ring 6 on the cover plate 3 from the ring groove 5. At this time, the worn tooth head is found, and the part of the tooth head is pulled out from the slot 10, and the new tooth head is replaced in the slot 10. Then, the positioning ring 6 on the cover plate 3 is inserted into the ring groove 5, and the cover plate 3 is covered on the ring body 2. Then, the first nut 9 is rotated by a screwdriver to fix the cover plate 3 to the ring body 2, thereby fixing the replaced tooth head. There is no need to replace the entire gear after the gear tooth head is damaged, thereby reducing costs.
[0029] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, a plurality of groups of extrusion cavities 12 are provided in the ring body 2, and each group of extrusion cavities 12 is connected with each group of slots 10. An extrusion hole 13 is provided on the ring body 2, and the extrusion hole 13 is connected with the extrusion cavity 12, and one end of the extrusion hole 13 passes through the outer surface of the ring body 2, and the second nut 14 is installed by internal thread through one end of the extrusion hole 13 passing through the ring body 2, and a through hole 15 for installing the gear is provided in the central part of the gear body 1.

[0032] The cross-sectional shape of the extrusion hole 13 is L-shaped.
[0033] The volume of the extrusion cavity 12 is smaller than the volume of the insertion slot 10 .
[0034] By adopting the above technical solution, when the gear body 1 is used for too long, the extrusion cavity 12 is squeezed for a long time because the gear body 1 is squeezed, and the extrusion cavity 12 is deformed, resulting in the detachable tooth head being firmly attached to the deformed extrusion cavity 12, and it is difficult to pry it out by external force alone. Therefore, at this time, the second nut 14 can be rotated by a screwdriver, and the second nut 14 rotates and moves toward the inside of the extrusion hole 13, thereby pushing the lubricating oil inside the extrusion hole 13 into the extrusion cavity 12, and then squeezing the slot 10 connected to the extrusion cavity 12, and the tooth row group 4 inside the slot 10 is squeezed, so that the damaged tooth head is taken out, and the tooth head is removed by rotating the thread, and the worn tooth head can be replaced without manually prying off the tooth head, which is convenient for disassembly.
[0035] Working principle: After working for a long time, the tooth head of the gear is worn, resulting in a decrease in the performance of the gear row. When the gear needs to be replaced, first use a screwdriver to rotate the first nut 9 to remove the first nut 9 from the first threaded hole 7 and the second threaded hole 8, and then remove the cover plate 3 to separate the positioning ring 6 on the cover plate 3 from the ring groove 5. At this time, find the worn tooth head, pull out the part of the tooth head from the slot 10, replace the new tooth head in the slot 10, and then insert the positioning ring 6 on the cover plate 3 into the ring groove 5, cover the cover plate 3 on the ring body 2, and then rotate the first nut 9 with a screwdriver to fix the cover plate 3 to the ring body 2, thereby fixing the replaced tooth head. There is no need to replace the entire gear after the gear tooth head is damaged, thereby reducing costs.
