[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0030] In the description of this specification, the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0031] like Figures 1 to 10 As shown, a sprocket that is easy to maintain includes a fixed plate 1 and a mounting plate 2 fixed to each other. The fixed plate 1 is provided with a bolt 11 and a bolt 12. The bolt 11 and the bolt 12 pass through the fixed plate 1 and are screwed on the mounting plate 2. The bolt 11 and the bolt 12 are fixed to the mounting plate 2 in the inner and outer circumferential directions so that the fixed plate 1 and the mounting plate 2 are tightly mounted together.

[0032] The mounting plate 2 is provided with a slot 21 for the sprocket teeth 3 to be inserted into. The slot 21 extends from the outside to the inside and is circumferentially distributed on the outer periphery of the mounting plate. There are multiple sprocket teeth 3 and they are inserted into the slot 21 one by one. The two sides of the sprocket teeth 3 abut against the two sides of the slot 21, that is, the sprocket teeth 3 are evenly distributed on the outer periphery of the mounting plate 2.

[0033] The mounting plate 2 is provided with an insertion hole 22 corresponding to the position of the sprocket tooth 3, and the sprocket tooth 3 is provided with a limiting hole 32 corresponding to the position of the insertion hole 22. A pin 23 connected to the sprocket tooth 3 is fixed in the insertion hole 22, and the pin 23 is threadedly installed in the insertion hole 22. The pin 23 is inserted into the limiting hole 32 and abuts against the limiting hole 32 inside and outside to fix the sprocket tooth 3 in the slot 21.

[0034] When the sprocket 3 needs to be disassembled, the latch 23 can be screwed out of the insertion hole 22 so that the sprocket 3 can be taken out from the slot 21 and replaced.

[0035] The installation of the sprocket teeth 3 is limited by the slot 21 to ensure the stability of the use of the sprocket teeth 3. A card slot 13 is provided on the fixed plate 1, and a card plate 31 is provided on the sprocket teeth 3 to be inserted into the card slot 13. The card plate 31 is inserted into the card slot 13 to further improve the stability of the use of the sprocket teeth 3.

[0036] The sprocket teeth 3 are fixed by plugging in the latch 23 so that the worn sprocket teeth 3 can be quickly replaced, which greatly reduces the maintenance cost and improves the efficiency of replacing the sprocket teeth 3. Moreover, the sprocket teeth 3 can be detachably replaced by the latch 23. Compared with the existing method of directly replacing the sprocket, there is no need to disassemble other matching parts. Only the corresponding sprocket teeth 3 need to be replaced through the latch 23, thereby improving the convenience of sprocket replacement.

[0037] To further improve the reliability of the sprocket 3, a side groove 33 is formed on one side of the sprocket 3. The mounting plate 2 is provided with a fixing hole 26 and a slide groove 24 connected to the side groove 33. The fixing hole 26 extends from the outside to the inside into the slide groove 24. A slide plate 25 is slidably installed in the slide groove 24. A limit pin 27 is installed in the fixing hole 26 and is threadedly mounted in the fixing hole 26.

[0038] By tightening the limit pin 27 inward, the limit pin 27 moves inward to squeeze the slide plate 25 to slide to the side groove 33, and then the slide plate 25 abuts against the outward displacement of the limit sprocket teeth 3 to ensure the stability of the use of the sprocket teeth 3 and prevent the sprocket teeth 3 from loosening, thereby ensuring the reliability of the use of the sprocket.

[0039] One end of the limiting pin 27 is provided with a tapered portion 271 that abuts against the slide plate 25. The tapered portion 271 abuts against and squeezes the slide plate 25, making the abutting and limiting action of the slide plate 25 on the sprocket teeth 3 smoother and more reliable.

[0040] When the sprocket tooth 3 needs to be removed, the limit pin 27 is unscrewed outward so that the slide plate 25 can be separated from the side groove 33. That is, after the limit pin 27 is unscrewed, the sprocket can be rotated so that the slide plate 25 can be moved away from the side groove 33 under the action of gravity, and then the corresponding sprocket tooth 3 can be removed outward to replace the sprocket tooth 3.

[0041] The inner periphery of the fixed plate 1 is provided with a shaft sleeve 4 , and the shaft sleeve 4 is fixed to the fixed plate 1 by a second bolt 12 so as to be transmission-connected with an external transmission shaft through the shaft sleeve 4 .

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
