Description

Technical Field

[0001] This application relates to the field of crushers, and more particularly to a live tooth cap structure for a toothed roll crusher. Background Technology

[0002] Toothed roll crushers are equipment suitable for industries such as coal, metallurgy, mining, chemical, and building materials. They are especially suitable for crushing raw coal in large coal mines or coal preparation plants.

[0003] The teeth on the toothed rollers of a toothed roller crusher are the key components for crushing materials. They typically operate in harsh environments and are prone to wear and damage. Traditional toothed roller structures are generally of an integral design, with the teeth cast entirely onto the roller or cast as a toothed ring structure. Once worn or damaged, the entire toothed roller or toothed ring must be disassembled and replaced, which is costly, time-consuming, and labor-intensive. Utility Model Content

[0004] To facilitate tooth replacement and reduce maintenance costs of toothed roll crushers, this application provides a live tooth cap structure for toothed roll crushers.

[0005] The technical solution provided in this application for a live tooth cap structure for a toothed roll crusher is as follows: A live tooth cap structure for a toothed roller crusher includes a toothed roller sleeve, a plurality of evenly distributed tooth seats are provided on the outer side of the toothed roller sleeve, a tooth cap is detachably connected to the tooth seat, and a live tooth is detachably connected to the end of the tooth cap away from the toothed roller sleeve, and all the live teeth are located on the same side of the tooth cap.

[0006] By adopting the above technical solution, both the live tooth and the tooth cap are detachable structures. Therefore, when the live tooth or the tooth cap is worn or even damaged, it can be disassembled and replaced separately without replacing the entire tooth roller or tooth ring, thereby reducing replacement costs and improving maintenance efficiency.

[0007] Optionally, the tooth cap covers the tooth seat, and a connecting bolt passes through between the tooth cap and the tooth seat. A connecting nut is provided on the connecting bolt, and a countersunk groove is provided on the tooth cap to accommodate the connecting nut and the connecting bolt.

[0008] By adopting the above technical solution and using connecting bolts and nuts to fix the tooth cap on the tooth base, the stability of the tooth cap connection is ensured, and the loosening or falling off of the tooth cap due to vibration or impact is reduced.

[0009] Optionally, the movable tooth is thick at one end and thin at the other end. The thin end of the movable tooth passes through the tooth cap and is threaded with a fixing nut. The center line of the movable tooth is set perpendicular to the radius of the toothed roller sleeve.

[0010] By adopting the above technical solution, the structure of the live tooth, which is thick at one end and thin at the other, allows the live tooth to move only in one direction after being installed on the tooth cap. When the thicker end of the live tooth is engaged in crushing work, the tooth cap provides stable support for the live tooth, thereby improving the stability and reliability of the live tooth.

[0011] Optionally, the tooth cap is provided with a limiting block, and the coarse end of the live tooth is provided with a limiting groove, and the limiting block is inserted into the limiting groove.

[0012] By adopting the above technical solution, the limiting block and the limiting groove are inserted and matched, so that the live tooth does not rotate relative to the tooth cap, thereby reducing the rotation of the live tooth relative to the tooth cap due to vibration or impact, and thus affecting the stability of the connection between the live tooth and the fixed nut.

[0013] Optionally, a protective plate is provided on the end face of the toothed cap away from the toothed roller sleeve, and the protective plate is installed on the toothed cap by fixing bolts.

[0014] By adopting the above technical solution, when the toothed cap impacts the material to be crushed, the protective plate protects the top of the toothed cap, reduces the wear of the toothed cap, and thus extends the service life of the toothed cap.

[0015] Optionally, a reinforcing plate is provided on both sides of the toothed cap, and the reinforcing plate abuts against the toothed roller sleeve.

[0016] By adopting the above technical solution, the reinforcing plate increases the contact area of ​​the tooth seat of the tooth cap, thereby improving the support of the tooth seat for the tooth cap and improving the stability of the tooth cap.

[0017] Optionally, a keyway is provided on the inner side of the toothed roller sleeve, a toothed roller is provided inside the toothed roller sleeve, and a flat key is provided on the toothed roller that is inserted into the keyway.

[0018] Optionally, the tooth base is provided with a protrusion at its top, and the tooth cap is provided with a groove that mates with the protrusion inside.

[0019] By adopting the above technical solution, the cooperation between the protrusion and the groove makes it less likely for the tooth cap and the tooth seat to shift, thus improving the stability of the tooth cap.

[0020] In summary, this application includes at least one of the following beneficial technical effects: The tooth head and tooth cap are detachably connected. When the tooth head is worn or damaged, only the tooth head needs to be replaced, without replacing the entire tooth cap, which greatly reduces replacement costs and maintenance time. By using bolts and nuts to secure the teeth, the stability and reliability of the teeth during the crushing process are ensured, preventing loosening or detachment due to vibration or impact.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a live tooth cap structure for a toothed roller crusher. (Refer to...) Figure 1 and Figure 2 A toothed cap structure for a toothed roll crusher includes a toothed roll sleeve 1, with four evenly distributed tooth seats 11 fixed on the outer side of the toothed roll sleeve 1. Two opposing keyways 12 are formed on the inner side of the toothed roll sleeve 1. When a toothed roll is installed inside the toothed roll sleeve 1, a flat key that mates with the keyway 12 is fixed on the toothed roll, and the flat key is inserted into the keyway 12. When the toothed roll rotates, it drives the toothed roll sleeve 1 to rotate, thereby driving the tooth seats 11 to rotate.

[0027] A toothed cap 2 is detachably connected to the toothed seat 11. A movable tooth 3 is detachably connected to the end of the toothed cap 2 furthest from the toothed roller sleeve 1, and all movable teeth 3 are located on the same side of the toothed cap 2. The toothed cap 2 is made of wear-resistant alloy casting, possessing excellent wear resistance, while the movable teeth 3 are made of high-strength alloy, possessing high strength and good toughness. Both the movable teeth 3 and the toothed cap 2 are detachably connected, thus allowing for individual removal and replacement when either the movable tooth 3 or the toothed cap 2 is worn or damaged, without the need to replace the entire toothed roller or toothed roller sleeve 1.

[0028] A toothed cap 2 fits onto a toothed seat 11, and a connecting bolt 21 passes between the toothed cap 2 and the toothed seat 11. A connecting nut 22 is provided on the connecting bolt 21. The connecting bolt 21 and the connecting nut 22 cooperate to fix the toothed cap 2 and the toothed seat 11 together. The toothed cap 2 has a countersunk groove to accommodate the nut 22 and the connecting bolt 21. A protrusion 111 is provided at the top of the toothed seat 11, and a groove 23 that mates with the protrusion 111 is provided inside the toothed cap 2. The cooperation between the protrusion 111 and the groove 23 makes it less likely for the toothed cap 2 and the toothed seat 11 to shift, thus improving the stability of the toothed cap 2.

[0029] The movable tooth 3 is thick at one end and thin at the other end. The thin end of the movable tooth 3 passes through the tooth cap 2, and the tooth cap 2 has a through hole 24 that matches the shape of the movable tooth 3. The thinner end of the movable tooth 3 passes through the through hole 24 and is threadedly connected to a fixing nut 31. The center line of the movable tooth 3 is set perpendicular to the radius of the toothed roller sleeve 1.

[0030] The connection between the tooth cap 2 and the tooth base 11 is ensured by using connecting bolts 21 and connecting nuts 22. Similarly, the movable tooth 3 is fixed to the tooth cap 2 by fixing nuts 31, thereby reducing the risk of loosening or falling off the tooth cap 2 or the movable tooth 3 due to vibration or impact. The structure of the movable tooth 3, which is thicker at one end and thinner at the other, allows it to move only in one direction after being installed on the tooth cap 2. When the thicker end of the movable tooth 3 is engaged in crushing operations, the tooth cap 2 provides stable support for the movable tooth 3, further improving its stability and reliability.

[0031] A limiting block 25 is fixed on the tooth cap 2, and a limiting groove 32 is opened at the coarse end of the movable tooth 3, with the limiting block 25 inserted into the limiting groove 32. The limiting block 25 and the limiting groove 32 are engaged to prevent the movable tooth 3 from rotating relative to the tooth cap 2, thereby reducing the rotation of the movable tooth 3 relative to the tooth cap 2 due to vibration or impact, which would affect the stability of the connection between the movable tooth 3 and the fixed nut 31.

[0032] Reference Figure 1 and Figure 3 A protective plate 26 is provided on the end face of the toothed cap 2 away from the toothed roller sleeve 1. The protective plate 26 is installed on the toothed cap 2 by fixing bolts. Reinforcing plates 27 are provided on both sides of the toothed cap 2, and the reinforcing plates 27 abut against the toothed roller sleeve 1.

[0033] When the toothed cap 2 impacts the material to be crushed, the protective plate 26 protects the top of the toothed cap 2, reducing wear and extending its service life. The reinforcing plate 27 increases the contact area of ​​the tooth seat 11 of the toothed cap 2, thereby improving the support of the tooth seat 11 for the toothed cap 2 and enhancing its stability.

[0034] The implementation principle of the live tooth cap structure for a toothed roller crusher according to an embodiment of this application is as follows: During the operation of the toothed roller crusher, the material is crushed by the live teeth 3 through the gap between the toothed rollers. Since the live teeth 3 are made of high-strength alloy, they can effectively withstand the high stress and impact generated during the crushing process, while the main body of the tooth cap 2 is cast from wear-resistant alloy, effectively resisting material wear. When the tooth head is worn or damaged, simply loosen the fixing nut 31, replace the live tooth 3, and then retighten the fixing nut 31. When the tooth cap 2 is worn or damaged, loosen the connecting bolt 21, replace the tooth cap 2, and then retighten the connecting bolt 21.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
