Cone crusher

Abstract

The invention belongs to the technical field of crushing, grinding or pulverizing equipment, and discloses a cone crusher. The cone crusher comprises a machine frame and a crushing base, wherein a crushing cavity is formed in the crushing base; a mounting shaft is further arranged on the machine frame; a crushing roll is arranged on the mounting shaft; a rotating shaft and a motor are further arranged on the machine frame; the rotating shaft and the mounting shaft achieve transmission through bevel gears; a collecting box is further arranged on the machine frame; a cam is further arranged on the rotating shaft; sieve plates in inclined arrangement are connected to the side wall of the collecting box in a sliding manner; the ends, near the mounting shaft, of the sieve plates are lower thanthe other ends; the sieve plates are pressed against the mounting shaft; springs are arranged between the sieve plates and the bottom of the collecting box; a vertical material collecting through is formed in the bottom of the mounting shaft; material guiding ports communicated with the material collecting through are formed in the side wall of the mounting shaft and below the sieve plates; a discharge port is formed in the bottom of the collecting box and below the material collecting through. The cone crusher solves the problem that in the prior art, the particle size of the crushed materialis nonuniform due to falling of the material with the relatively large particle size because the distance between one side of the crushing roll and the crushing cavity becomes larger when an eccentric sleeve drives the crushing roll to do rotating and swinging motion.

Description

technical field [0001] The invention belongs to the field of crushing, grinding or pulverizing equipment, and in particular relates to a cone crusher. Background technique [0002] Cone crusher is a crushing machine used for raw material crushing. Because of its characteristics of large crushing ratio, high efficiency, low energy consumption, and uniform particle size after crushing, it is widely used in raw material crushing in various fields such as mining, smelting, building materials, roads, railways, water conservancy and chemical industries. [0003] The existing cone crusher includes a crushing seat with a crushing cavity and a crushing roller located in the crushing cavity. The crushing seat is also provided with an eccentric drive mechanism. The eccentric drive mechanism includes a rotating shaft and a rotating motor for driving the rotating shaft. The driving bevel gear is equipped with an eccentric sleeve at the bottom of the crushing roller, and the driven bevel...

Problems solved by technology

[0005] The present invention intends to provide a cone crusher to solve the problem that in the prior art, when the eccentric sleeve drives the crushing roller to do a pendulum motion, the distance between one side of the crushing roller and the crushing cavity will become larger, so that the material with a larger particle size Falling, resulting in the problem of uneven particle size of the crushed material
