[0005] To achieve the above purpose, the utility model is implemented by the following technical scheme: a semi autogenous mill cylinder lining plate, comprising a mill cylinder and a lining plate, the lining plate is arranged on the inner wall of the mill cylinder, the front side and the rear side of the surface of the mill cylinder are provided with large aperture insertion grooves, and a plurality of large aperture insertion grooves are arranged at equal intervals, a large aperture threaded rod matched with the large aperture insertion groove is fixedly connected to the front side and the rear side of the bottom of the lining plate, a plurality of receiving grooves are arranged at equal intervals on the surface of the large aperture threaded rod and in the large aperture insertion groove, a sliding groove plate is slidably connected in the receiving groove, a pad is slidably connected to the surface of the sliding groove plate, a threaded sleeve is threadedly connected to the surface of the large aperture threaded rod, and a bracket matched with the pad is rotatably arranged on the top of the threaded sleeve through a bearing.

[0006] Preferably, the top of the pad and the bracket is respectively fixedly connected with a first rubber pad and a second rubber pad.

[0007] Preferably, the first reset spring is fixedly connected between the chute plate and the receiving groove.

[0008] Preferably, the surface of the cushion block is provided with a plurality of rolling balls.

[0009] Preferably, a flared opening is formed at the entrance of the large-aperture slot.

[0010] Beneficial effects

[0011] The utility model provides a kind of semi-autogenous mill cylinder lining plate.Compared with prior art, it has the following beneficial effects: the utility model is provided with the cushion block capable of retracting horizontally and longitudinally in the receiving groove, so that the lining plate can be installed conveniently by avoiding the problem of easy falling off of the lining plate during inclined installation of the lining plate through the cooperation of large-aperture slot, large-diameter threaded rod and cushion block;secondly, the bracket matched with the cushion block is rotatably arranged on the top of the threaded sleeve, and the first rubber pad and the second rubber pad are respectively arranged on the top of the cushion block and the bracket, so that the threaded sleeve can be locked to the large-diameter threaded rod through the first rubber pad and the second rubber pad simultaneously.
