The shot blasting machine has models of various specifications and models according to different workpieces and production modes, but the shot blasting machine is adopted to carry steel shots or other abrasive materials out to strike and rub the surfaces of the workpieces to remove attachments and oxide layers, a shot blasting wheel is generally arranged in a shot blasting machine main body, one end of the shot blasting wheel is connected with a rotating shaft through a bolt and is connected with a rotating motor through the rotating shaft, the inner cavity of the shot blasting wheel is communicated with a shot material leading-in pipe in shot blasting operation, the steel shots can directly impact the shot blasting wheel, so that the fastener is seriously abraded, the fastener is frequently replaced, even is not easily detached under the condition of serious abrasion, the maintenance time is wasted, and the risk exists in the operation of the equipment.

The fastening bolt of the shot separating wheel of the shot blasting machine is directly contacted with a steel shot grinding material, no protective measure is provided, a high-strength bolt is adopted aiming at the phenomenon of short service life, and the situation that the bolt needs to be frequently replaced and is not easy to disassemble still exists.

Most of bolt protective sleeves are made of single plastic or rubber materials, although the rubber materials are good in damping and buffering effects, the bolt protective sleeves are easy to age and low in tear strength, and although the plastic materials are high in hardness and tear strength, the bolt protective sleeves are poor in damping and buffering effects and easy to damage due to external pressure.

Therefore, there is a need to provide a new solution.
