Description

Jaw crusher

Technical Field

The utility model belongs to the technical field of the stone is broken, especially, relate to a jaw crusher.

Background

Jaw crusher is commonly called as jaw crusher, also called as tiger mouth, and is a crusher which is characterized in that a crushing cavity is formed by a movable jaw plate and a fixed jaw plate, and the two jaws of an animal are simulated to move so as to finish the material crushing operation. The jaw crusher is widely used in the industries of mine smelting, building materials, highways, railways, water conservancy, chemical engineering and the like. The jaw crusher consists of mainly motor, eccentric shaft, belt pulley, flywheel, movable jaw, side protecting plate, toggle plate back seat, gap regulating screw, reset spring, fixed jaw and movable jaw. The working principle is as follows: the motor drives the belt and the belt pulley, the movable jaw moves up and down through the eccentric shaft, an included angle between the toggle plate and the movable jaw is enlarged when the movable jaw ascends, so that the movable jaw is pushed to approach the fixed jaw, and meanwhile, materials placed in a crushing cavity formed by the movable jaw and the fixed jaw are crushed or split, so that the purpose of crushing is achieved; when the movable jaw moves downwards, the included angle between the toggle plate and the movable jaw is reduced, the movable jaw leaves the fixed jaw under the action of the return spring, the crushed material is discharged from a discharge opening of the crushing cavity, the movable jaw moves periodically along with the continuous rotation of the motor to crush the material, and the crushed material is crushed into ideal particles and discharged from the discharge opening.

Jaw breaker can produce a large amount of dust at the in-process that carries out the material breakage, and the dust dispersion not only brings very big harm for operating personnel in the air, has also caused the pollution to the environment moreover, consequently need install dust collector additional on jaw breaker. However, jaw crushers with dust removing devices in the prior art have various disadvantages: if the air exhaust pipe for extracting dust extends into the crushing cavity, when the material is crushed, the distance between the movable jaw plate and the fixed jaw plate is changed continuously, so that the air exhaust pipe is extruded by stones continuously, the air exhaust effect is poor, and the service life is also shortened; the dust hood is arranged above the crusher and only covers the feed inlet, and the jaw crusher is not completely surrounded by the dust hood, so that a certain distance is reserved between the dust hood and the top of the jaw crusher, the structure is not tight, the dust removal effect is poor, and the noise is loud.
