Problems solved by technology

However, the structure of the fixed cone frame of the existing cone crusher is single, and the connection strength is insufficient, which leads to the easy loosening of the fixed cone liner; and the fixed cone liner of the existing cone crusher is rigidly fixed. The cone crusher will generate a huge load, and the rigidly connected fixed cone liner will cause the frame to vibrate strongly. The frame is prone to cracks when it vibrates for a long time and the collision of stones, which seriously affects its service life.

Embodiment Construction

[0020] The preferred embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] like Figure 1~Figure 6 The shown cone crusher includes a frame 1 and a moving cone group 5 arranged in the frame 1 .

[0022] Moving cone group:

[0023] The moving cone group 5 includes a moving cone shaft 51, a moving cone body 52 and a moving cone liner 53, the outer surface of the moving cone 52 is tapered, and the inside of the moving cone 52 is provided with a step with a large diameter at the lower part and a small diameter at the top Through hole; the stepped through hole runs through the upper and lower ends of the moving cone 52 , and the stepped through hole is divided into a lower bearing mounting hole 521 , a middle shaft mounting hole 522 and an upper shaft top mounting hole 523 . The moving cone shaft 51 is composed of a moving cone shaft body 511 and a moving cone shaft top 512 disposed above the moving c...

Abstract

The invention relates to the field of mining equipment and in particular relates to a cone crusher. The cone crusher comprises a rack and a movable cone group arranged in the rack, wherein the movable cone group consists of a movable cone shaft, a movable cone body which sleeves the outer side of the movable cone shaft and a movable cone liner which sleeves the outer side of the movable cone body; the rack consists of a fixed cone frame arranged at the upper side, the fixed cone frame consists of a fixed cone body and a fixed cone liner which is arranged in the fixed cone body, and a crushing cavity is formed between the fixed cone liner and the movable cone liner. The cone crusher is high in fixed cone connection strength and has the damping effect.

Description

technical field [0001] The invention relates to the field of mining equipment, in particular to a cone crusher. Background technique [0002] The cone crusher is a kind of mining machinery used for crushing stones. Its working principle is to drive the movable cone main shaft group to eccentrically swing through the eccentric mechanism. Cooperate with each other to crush stones. However, the structure of the fixed cone frame of the existing cone crusher is single, and the connection strength is insufficient, which leads to the easy loosening of the fixed cone liner; and the fixed cone liner of the existing cone crusher is rigidly fixed. The cone crusher will generate a huge load, and the rigidly connected fixed cone liner will cause the frame to vibrate strongly. The frame is prone to cracks during long-term vibration and stone collision, which seriously affects its service life. Contents of the invention [0003] In order to solve the above problems, the purpose of the ...
