Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] In the embodiments of the present application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, a first feature being "above," "above," and "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0040] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the embodiments of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art can combine and combine different embodiments or examples described in this specification and the features of different embodiments or examples, unless they are contradictory.

[0041] The present utility model is implemented as follows Figures 1-6 As shown in the figure, a toothed cutter ring and toothed device is provided, comprising a cutter body 100, wherein a first cutter tooth 200 and a second cutter tooth 300 are provided on the outer wall of the cutter body 100, wherein the first cutter tooth 200 and the second cutter tooth 300 are spaced apart, and the length of the first cutter tooth 200 is greater than the length of the second cutter tooth 300, or the length of the second cutter tooth 300 is greater than the length of the first cutter tooth 200. Furthermore, by manufacturing the first cutter tooth 200 and the second cutter tooth 300 with different lengths, the product cost is reduced without affecting the use effect, and the rock breaking efficiency and effect are further improved. The cutter teeth of different lengths can form a more complex cutting path during rotation, optimize the cutting force distribution, reduce the situation where a single point is subjected to excessive force, and thus improve the rock breaking efficiency. At the same time, the long cutter teeth penetrate deep into the rock to form a larger crushing pit, and the short cutter teeth perform fine cutting on the rock surface. The two teeth cooperate with each other to produce a better crushing effect, thereby improving the rock crushing rate and crushing quality.

[0042] In this embodiment, the first cutting tooth 200 and the second cutting tooth 300 are both flat. Furthermore, the flat shape improves the utilization rate of materials and reduces material waste, thereby helping to reduce costs. The flat design enables the cutting teeth to better adapt to rocks of different hardness and properties, thereby improving the adaptability and flexibility of the equipment.

[0043] See Figure 1-Figure 5In this embodiment, the first tooth 200 includes a first tooth seat 201, a first tooth groove 202 provided on the first tooth seat 201, and a first metal tooth 203 embedded in the first tooth groove 202. The second tooth 300 includes a second tooth seat 301, a second tooth groove 302 provided on the second tooth seat 301, and a second metal tooth 303 embedded in the second tooth groove 302. Furthermore, the first metal tooth 203 is interference-connected with the first tooth groove 202, and the second metal tooth 303 is interference-connected with the second tooth groove 302. The tooth seat provides a stable support for the metal tooth, so that the metal tooth is not easy to loosen or fall off during the cutting process, thereby enhancing the structural strength and stability of the tooth. The tooth seat can optimize the stress distribution during the cutting process, reduce stress concentration, and improve the bearing capacity and service life of the tooth. Optionally, two opposing arc surfaces 500 are provided at the end of the first tooth away from the first tooth groove, and two opposing arc surfaces 500 are also provided at the end of the second tooth away from the second tooth groove.

[0044] In this embodiment, the first tooth seat 201 and the second tooth seat 301 have the same length, the first metal tooth 203 and the second metal tooth 303 have the same length, and the depth of the first tooth groove 202 is greater than the depth of the second tooth groove 302; or the first tooth seat 201 and the second tooth seat 301 have the same length, the first metal tooth 203 and the second metal tooth 303 have the same length, and the depth of the first tooth groove 202 is less than the depth of the second tooth groove 302. Furthermore, by reducing the depth of the first tooth groove 202 or the second tooth groove 302, the use of materials is reduced, thereby achieving the purpose of reducing costs.

[0045] In this embodiment, the first tooth seat 201 and the second tooth seat 301 have the same length, the first tooth groove 202 and the second tooth groove 302 have the same depth, and the length of the first metal tooth 203 is greater than the length of the second metal tooth 303; or the first tooth seat 201 and the second tooth seat 301 have the same length, the first tooth groove 202 and the second tooth groove 302 have the same depth, and the length of the first metal tooth 203 is less than the length of the second metal tooth 303. Furthermore, by reducing the length of the first metal tooth 203 or the second metal tooth 303, the use of materials is reduced, thereby achieving the purpose of reducing costs.

[0046] In this embodiment, a tungsten carbide particle cladding layer 400 is provided on both surfaces of the outer edge of the blade body 100. Furthermore, tungsten carbide is a material with extremely high hardness, second only to diamond. Providing a tungsten carbide particle cladding layer 400 on the outer edge of the blade body 100 can significantly improve the wear resistance of the blade body 100, reduce wear during the cutting process, and thus extend the service life of the blade body 100. The tungsten carbide particles are evenly distributed in the cladding layer, forming a hard protective layer. When the blade body 100 comes into contact with rock or other hard materials, this protective layer can resist various wear mechanisms such as abrasive particle wear, hard surface wear, and sediment erosion wear, thereby maintaining the cutting performance of the blade body 100.

[0047] In this embodiment, the depth of the first tooth groove 202 is 21.58 mm to 21.78 mm, and the depth of the second tooth groove 302 is 25.58 mm to 25.78 mm; or

[0048] The depth of the first tooth groove 202 is 25.58-25.78 mm, and the depth of the second tooth groove 302 is 21.58-21.78 mm. In this embodiment, the depth of the first tooth groove 202 is 21.68 mm, and the depth of the second tooth groove 302 is 25.68 mm.

[0049] In this embodiment, the bottom cross-sections of the first and second tooth grooves 202 and 302 are wedge-shaped, and the bottom cross-sections of the first and second metal teeth 203 and 303 are also wedge-shaped. Furthermore, the wedge-shaped bottoms of the metal teeth and the tooth grooves facilitate the interference fit between the metal teeth and the tooth grooves. The metal teeth with wedge-shaped bottom cross-sections can better disperse stress during the cutting process. When the metal teeth are subjected to cutting forces, the stress is distributed along the wedge-shaped cross-section rather than concentrated at a single point. This reduces wear and damage caused by localized stress concentration, thereby extending the service life of the metal teeth.

[0050] In this embodiment, the thickness of the blade body 100 is 88.6 mm-89 mm. Optionally, the thickness of the blade body 100 is 88.8 mm.

[0051] In this embodiment, the diameter of the blade body 100 is 327.82 mm-327.88 mm. Optionally, the diameter of the blade body 100 is 327.85 mm.

[0052] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims attached to this utility model.
