Description

Technical Field

[0001] This utility model relates to the technical field of wear-resistant grinding mechanisms, and in particular to an adjustable-gap wear-resistant grinding mechanism for a mining crusher. Background Technology

[0002] The wear-resistant grinding mechanism of a mining crusher is a key component in the crushing equipment that withstands high-intensity impact and wear. Its core function is to achieve crushing and grinding operations through direct contact with the ore, while also possessing excellent wear resistance to extend its service life.

[0003] For example, Chinese Utility Model Patent Application No. 202123169469.2 discloses an adjustable-gap wear-resistant grinding roller for a mining crusher. The adjustable-gap wear-resistant grinding roller for a mining crusher includes two sets of grinding roller bodies arranged in parallel, and further includes: a clamp, on which the grinding roller bodies are rotatably mounted, and a clamp is provided on the outside of each grinding roller body; and a drive assembly connected to the clamp, which drives the clamp and the grinding roller bodies mounted on the clamp to move horizontally. In the adjustable-gap wear-resistant grinding roller for a mining crusher provided by this utility model, the distance between the two sets of rollers can be adjusted by the drive assembly. Therefore, when processing stones of different sizes, the adjustment of the roller shaft makes the entire crusher more suitable for processing stones of that size, resulting in better processing effect and higher safety.

[0004] However, the aforementioned wear-resistant grinding rollers require two sets of rollers to move synchronously during use. Although the spacing can be adjusted, wear can easily lead to asynchronous movement, and assembly and maintenance are cumbersome, affecting service life. Therefore, those skilled in the art provide an adjustable-spacing wear-resistant grinding mechanism for mining crushers to solve the problems mentioned in the background art. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Reference Figure 1-4 The present invention provides an adjustable spacing wear-resistant grinding mechanism for a mining crusher, including a fixed base 1, a fixed bracket 2 fixed on the top of the fixed base 1, a first arm 3 fixed on the top of the fixed bracket 2, a first wear-resistant grinding roller body 4 installed between the inner walls of the two sides of the first arm 3, a spacing adjustment mechanism 5 provided on the top of the fixed base 1, and a reinforcement mechanism 6 provided on the outside of the spacing adjustment mechanism 5.

[0036] The spacing adjustment mechanism 5 includes a servo motor 51. A ball screw 52 is fixed to the outer side of the output shaft of the servo motor 51. A ball nut 53 is threaded onto the outer side of the ball screw 52. A movable bracket 54 is fixed to one side of the ball nut 53. A support sliding block 55 is fixed to one side of the movable bracket 54. A support rail 56 is fixed to the top of the fixed base 1. A reinforcing connecting block 57 is installed on the top of the movable bracket 54. A second arm 58 is fixed to the outer side of the reinforcing connecting block 57. A reinforcing connecting seat 510 is fixed between the inner walls of the two sides of the second arm 58. A second wear-resistant grinding roller body 59 is fitted between the inner walls of the two sides of the second arm 58. A mounting connecting frame 511 is fixed to one side of the reinforcing connecting seat 510. A roller bracket 512 is fixed to the bottom of the connecting frame 511. A support roller 513 is rotatably connected between the inner walls of the two sides of the roller bracket 512 via a rotating shaft. The support roller 513 plays a role in auxiliary support and guidance. The servo motor 51 is fixedly connected to the fixed seat 1. The support sliding block 55 is slidably connected to the support rail 56. When the moving bracket 54 moves, it can drive the support sliding block 55 to slide on the outside of the support rail 56. A through hole is opened inside the moving bracket 54. The size of the through hole is adapted to the size of the ball screw 52, ​​so that the moving bracket 54 can move horizontally. The reinforcing connecting seat 510 and the second connecting frame 58 are fixed together by bolts. The support rail 56 and the fixed seat 1 are fixed together by bolts.

[0037] The reinforcement mechanism 6 includes a support plate 61, a reinforcement bracket 62 fixed to the bottom of the support plate 61, a lifting threaded column 63 movably inserted through the bottom of the support plate 61, a handle pad 64 fixed to the bottom of the lifting threaded column 63, a support pad 65 fixed to the bottom of the lifting threaded column 63, a counterweight block 66 installed on the top of the support pad 65, two positioning threaded sleeves 67 threadedly connected to the outer side of the lifting threaded column 63, the support plate 61 and the reinforcement connecting seat 510 fixedly connected, the reinforcement bracket 62 and the reinforcement connecting seat 510 fixedly connected, and a through hole opened inside the support plate 61, the size of which is adapted to the size of the lifting threaded column 63.

[0038] Working principle: The system includes a spacing adjustment mechanism 5. When adjusting the spacing between the first wear-resistant grinding roller body 4 and the second wear-resistant grinding roller body 59, the servo motor 51 is activated. The output shaft of the servo motor 51 drives the ball screw 52 to rotate, causing the ball nut 53 to move horizontally and move the moving bracket 54. The moving bracket 54 can move the second armature 58 and the reinforcing connecting seat 510 via the reinforcing connecting block 57, thus adjusting the spacing between the second wear-resistant grinding roller body 59 and the first wear-resistant grinding roller body 4. As the moving bracket 54 moves, the support sliding block 55 slides outside the support track 56, providing guidance and support. This facilitates the adjustable spacing and avoids the problem of asynchronous movement caused by the simultaneous movement of the two sets of wear-resistant grinding rollers, ensuring the accuracy of the grinding roller spacing adjustment. The device features a consistent design, and the adjustable spacing of the second wear-resistant grinding roller body 59 reduces the number of lubrication points and vulnerable parts, making troubleshooting simpler, facilitating subsequent maintenance, and improving equipment utilization. The device is equipped with a reinforcement mechanism 6. After the reinforcement connecting seat 510 is moved to the appropriate position, the two positioning threaded sleeves 67 on the outer side of the lifting threaded column 63 can be rotated to move the corresponding surfaces of the positioning threaded sleeves 67 away from the support plate 61. Then, the handle pad 64 is pressed vertically to make the bottom surface of the support pad 65 fit against the top surface of the fixed seat 1. Finally, the two positioning threaded sleeves 67 are rotated again to make the corresponding surfaces of the two positioning threaded sleeves 67 fit against the support plate 61, conveniently fixing the position of the support pad 65, thus playing an auxiliary reinforcement role and helping to improve the stability of the outer support of the reinforcement connecting seat 510.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
