Problems solved by technology

[0004] The traditional jaw crusher has many disadvantages: the jaw plates are all flat plates, and the crushing efficiency is low; the jaw plates tend to heat up and become soft and fall off during the process of repeatedly hitting the material, which is not firm enough and not safe enough; The material is returned at the feed port to reduce the crushing efficiency

Embodiment Construction

[0025] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0026] Such as figure 1 , figure 2 and image 3 As shown, the jaw crusher of the present invention includes frame, motor, pulley, eccentric shaft, bearing, movable jaw group, fixed jaw group, toggle plate, adjustment seat, pull rod, spring, water spray pipe, saw blade and saw blade bolt . The rack includes side panels. The motor drives the connecting pulley. The pulley is connected eccentrically. The eccentric shaft is movably connected to the frame and sleeved in the bearing seat at the upper end of the movable jaw group. The bearing is arranged between the bearing seat and the eccentric shaft. The movable jaw group includes the movable jaw, the bearing seat, the movable jaw plate and the movable jaw bolt. The bearing seat is set on the top of the movable jaw, and the movable jaw plate is fixed to the movable jaw through the movable jaw bolts....

Abstract

The invention discloses a jaw crusher. The jaw crusher comprises a rack, a motor, a belt pulley, an eccentric shaft, a bearing, a moving jaw set, a fixed jaw set, a wrist plate, an adjusting seat, a pull rod, a spring, water spray pipes, saw blades and saw blade bolts. The water spray pipes are vertically arranged on the inner plate surfaces of side plates of the two sides of the rack correspondingly and located between moving jaw plates and fixed jaw plates. The water spray pipes are each provided with a row of first water spray holes facing the moving jaw plates and a row of second water spray holes facing the fixed jaw plates. First clamping grooves corresponding to the saw blades are formed in moving jaws at the gaps between the moving jaw plates. Second clamping grooves corresponding to the saw blades are formed in mixed jaws at gaps between the fixed jaw plates. Sawteeth of the first saw blade protrude out of the plate surfaces of the moving jaw plates. Sawteeth of the second saw blade protrude out of the plate surfaces of the fixed jaw plates. The jaw crush can improve the crushing efficiency, reduce heating deformation of jaw plates and decrease materials returning from a feed port.

Description

technical field [0001] The invention relates to a crusher, in particular to a jaw crusher. Background technique [0002] Jaw crusher is commonly known as jaw crusher. It consists of two jaw plates, the movable jaw and the fixed jaw. It simulates the movement of the two jaws of animals to complete material crushing. Crushing of various ores and bulk materials in and chemical industries. [0003] The working principle of the jaw crusher is to use the motor as the power to drive the eccentric shaft to rotate, and the eccentric shaft is connected to the movable jaw, so that the movable jaw swings back and forth on the side of the fixed jaw according to a predetermined track, so that the materials entering between the fixed jaw and the movable jaw It is pressed and crushed, and then the finished material is discharged through the lower discharge port. [0004] The traditional jaw crusher has many disadvantages: the jaw plates are all flat plates, and the crushing efficiency is ...
