AI Technical Summary

Technical Problem

During the rotation of the crusher hammer, hard materials such as calcium fluoride can get stuck in the gap between the hammer and the shaft, causing the hammer to become unable to move and resulting in a jamming problem.

Method used

Design a bamboo-joint type hammer pin, including a mounting bracket, a mounting shaft, a hammer body, a limiting component, and a main shaft. The hammer body has a gap between the inclined annular surface and the limiting component, which causes hard materials to fall off through vibration.

Benefits of technology

This effectively prevents the hammer from jamming, ensures that the hammer can move normally, and improves crushing efficiency.

[0006] Preferably, one end of the insert shaft is provided with a locking member locked on the mounting frame, and the mounting frame and the insert shaft are fixedly connected.

[0007] Preferably, the hammer head body rotates on the insert shaft, and the rotation range of the hammer head body is blocked by the main shaft body.

[0008] Preferably, the limit piece is attached to the mounting frame away from the hammer head body, and a gap is left between the limit piece and the insert shaft.

[0009] Compared with the prior art, the utility model has the beneficial effects as follows:

[0010] The utility model discloses a bamboo joint type hammer head pin shaft, through the left and right movement of hammer head body on the butt joint convex ring, cooperate the vibration produced in the process of knocking and breaking of hammer head body, make the hard material of calcium fluoride big particle that is difficult to squeeze and break between the carding of hammer head body and inclined ring surface fall off from the gap, avoid the situation that hammer head body is stuck. BRIEF DESCRIPTION OF DRAWINGS
