TECHNICAL FIELD

[0001] The present application relates to the technical field of crushing equipment, in particular to a cone crusher. BACKGROUND

[0002] The cone crusher is a commonly used crushing equipment, which is mainly used for crushing small stones. It has the characteristics of high efficiency, high productivity and easy maintenance.

[0003] The cone crusher mainly comprises a shell and a moving cone arranged in the shell. The shell is internally provided with a fixed jaw plate. The moving cone comprises an eccentric sleeve assembly, a main shaft and a moving cone. One end of the main shaft is rotatably connected to the shell. The moving cone is sleeved on the main shaft. The eccentric sleeve assembly is sleeved on the outside of the main shaft. The eccentric sleeve assembly can drive the one end of the main shaft to move along a circular path, so as to swing the moving cone. The moving cone and the fixed jaw plate form a crushing cavity. The moving cone swings to crush the material between the moving cone and the fixed jaw plate. In order to reduce the adhesion of dust on the eccentric sleeve assembly, a dustproof piece is arranged between the moving cone and the eccentric sleeve assembly. One side of the dustproof piece is inserted into the movable slot corresponding to the dustproof piece formed on the moving cone to adapt to the swing of the moving cone during the crushing process. The dustproof piece forms a dustproof cavity inside to protect the eccentric sleeve assembly.

[0004] Since the dustproof piece and the movable slot have a certain space for movement, the dustproof cavity inside the dustproof piece and the crushing cavity are in a state of mutual communication. The dustproof effect is limited, which reduces the service life of the eccentric sleeve assembly and further affects the service life of the cone crusher. CONTENT OF THE INVENTION

When the iron material passes through the crusher, the outer oil pipe of the oil cylinder is relieved, the piston 32 moves downward, and the iron block can be smoothly discharged, thereby reducing the damage of the moving cone 2.

[0031] With reference to Figure 2 A dustproof piece 4 is arranged between the cone body 21 and the bottom wall of the shell 1, one side of the dustproof piece 4 is fixed on the shell 1, and the other side extends towards the cone body 21. An active groove 41 is arranged on the cone body 21, and the side of the dustproof piece 4 away from the ground extends into the active groove 41. A dustproof cavity 42 is formed between the dustproof piece 4 and the main shaft 22.

The two sides of the support plate 611 perpendicular to the axis are connected with the end of the air conveying pipe 52, so that the mounting seat 61 is connected in series with the air conveying pipe 52. The filter core 62 is embedded in the installation cavity to realize the installation of the filter core 62. One end of the movable cover plate 612 corresponding to the end of the arc track line is rotationally connected to the support plate 611, which is defined as the fixed end. The other end is the movable end.
