AI Technical Summary
The existing ball mill liners wear out severely during use, resulting in frequent replacements and increased labor intensity for workers.
A buffer assembly is set between the liner body and the stress strip, including a moving groove, a buffer groove, a linkage plate, a guide hole, a guide post, a buffer spring, and an energy-absorbing pad. Through the combination of these components, the stress strip moves along the moving groove under the force of the stress strip, the linkage plate moves down to drive the guide hole to slide, the buffer spring is compressed, and the energy-absorbing pad absorbs the force, providing a secondary buffering effect.
This reduces the wear on the load-bearing strips, decreases the frequency of liner replacement, and reduces the labor intensity for workers.

[0023] As Figures 1-4As shown, the liner body 1 and the ball mill cylinder are connected through the mounting hole 2 and the mounting bolt 3, the number of the mounting hole 2 is four times the number of the liner body 1, the number of the mounting bolt 3 is equal to the number of the mounting hole 2, and they are matched, the number of the stress strip 4 is twice the number of the liner body 1, the stress strip 4 is a strip structure, the material of the stress strip 4 is the same as that of the liner body 1, and the liner body 1 and the stress strip 4 are connected through the buffer assembly 5, so that the installation of the stress strip 4 is facilitated.
[0024] As shown in the figure, Figures 1-5 The number of the moving groove 51 is two groups and is symmetrically distributed, the moving groove 51 is matched with the stress strip 4, the buffer groove 52 is communicated with the moving groove 51, the thickness of the buffer groove 52 is less than that of the liner body 1, the linkage plate 53 is fixedly connected with the stress strip 4, the linkage plate 53 is a rectangular plate structure, the linkage plate 53 is matched with the buffer groove 52, so that the movement between the stress strip 4 and the moving groove 51 is facilitated, and the linkage plate 53 is driven to move along the inside of the buffer groove 52.
[0025] As shown in the figure, Figures 1-5 The number of the guide hole 54 is several groups and is arrayed, the guide hole 54 penetrates the middle part of the linkage plate 53, the guide hole 54 is a cylindrical structure, the number of the guide column 55 is equal to that of the guide hole 54, and the two ends of the guide column 55 are fixedly connected with the buffer groove 52, the diameter of the guide column 55 is less than that of the guide hole 54, and they are matched, the number of the buffer spring 56 is equal to that of the guide column 55, and the buffer spring 56 is sleeved on the outside of the guide column 55, the two ends of the buffer spring 56 are connected with the linkage plate 53 and the buffer groove 52 respectively, the first energy-absorbing pad 57 and the second energy-absorbing pad 58 are fixedly connected with the linkage plate 53, and the first energy-absorbing pad 57 and the second energy-absorbing pad 58 correspond to each other, so that the buffering of the stress strip 4 after being stressed is facilitated, the direct stress of the stress strip 4 is reduced, the abrasion is reduced, and the service life is improved.

[0027] It should be noted that, through the setting of the buffer assembly 5, the force receiving strip 4 moves along the inside of the moving groove 51 under the force, and at the same time drives the linkage plate 53 to move downward along the inside of the buffer groove 52, and at the same time the linkage plate 53 drives the guide hole 54 to slide along the outside of the guide column 55 during the downward movement of the linkage plate 53, and then the buffer spring 56 is compressed, thereby absorbing the impact force of the force receiving strip 4. When the linkage plate 53 is lowered to the lowest position, the force of the linkage plate 53 is absorbed by the second energy-absorbing pad 58, which has a secondary buffering effect, until the external force is withdrawn. At this time, the linkage plate 53 is reset under the elastic potential energy of the buffer spring 56, and the linkage plate 53 is reset. During the resetting process of the linkage plate 53, the first energy-absorbing pad 57 will contact the top of the buffer groove 52 to absorb the elastic force, thereby preventing the linkage plate 53 from shaking under the elastic potential energy of the buffer spring 56, and ensuring that the force receiving strip 4 can timely buffer the next impact.
