Shearing crusher cutter and crushing shaft device

Abstract

The invention belongs to the technical field of fine crushing, and in particular, discloses a shearing crusher cutter and a crushing shaft device of a shearing crusher applying the cutter. The cutter comprises a cutter body, and a cutter shaft mounting hole formed in the center of the cutter body; and multiple main edges are arranged at the outer periphery of the cutter body, and are uniformly distributed on the outer peripheral edge of the cutter body with the cutter shaft mounting hole as the circle center. The cutter further comprises multiple sets of secondary edges; each set of secondary edges is arranged between two adjacent main edges; and the distances from the main edges to the cutter shaft mounting hole are larger than the distances from the secondary edges to the cutter shaft mounting hole. The crushing shaft device comprises a cutter shaft, and cutters mounted on the cutter shaft; at least two cutters are provided; and spacing sleeves are arranged between the cutter shaft and the cutters. The cutter can fully crush materials to be crushed to improve the crushing efficiency, and relatively prolongs the service life of a crushing shaft and a motor.

Description

technical field [0001] The invention belongs to the technical field of fine crushing, and in particular relates to a cutter of a shearing crusher and a crushing shaft device of a shearing crusher using the cutter. Background technique [0002] At present, the general material crushing device uses a motor to drive the rotation of the crushing shaft installed in the crushing box, and the cutter installed on the crushing shaft can rotate the material for cutting and crushing. Normally, the crusher cutter can break the hard block to be broken into smaller size, when the block to be crushed is introduced between two relatively moving crushing knives, the movement of the cutter makes the block to be crushed crushed. [0003] However, when the existing crushing tool breaks a relatively hard block to be broken, the crushing tool is easy to slip; or when a large block is to be broken, the tool cannot completely cut or crush it at one time, resulting in easy material jam. And the cru...

[0003] However, when the existing crushing tool breaks a relatively hard block to be broken, the crushing tool is easy to slip; or when a large block is to be broken, the tool cannot completely cut or crush it at one time, resulting in easy material jam

Moreover, the crushing shaft is also subjected to a very large resistance, which will deform the crushing shaft and cause damage, and at the same time cause the life of the motor to decrease or burn out the motor due to the failure to rotate normally.
