Abstract

The utility model discloses a crushing apparatus for materials which is composed of a crushing device, an actuating device, a protecting device, a machine frame, etc., characterized in that the two moving jaws of the crushing device are correspondingly suspended on each eccentric axis, forming a four bar linkage with toggle plates. Two toothed plates are respectively fixed on the two moving jaws, and the toothed plates together with the moving jaws pivot at each eccentric axis to swing synchronously and correspondingly. The first stage of the actuating device is belt driving while the second stage is gear driving, which makes the body run stably. The utility model has the advantages of simple structure, being convenient to be maintained and dismounted, and being firm and durable, etc.

Description

Butt-jaw high power crusher

The utility model belongs to the disintegrating apparatus of material.

For required disintegrating machines such as mine, cement, building materials, metallurgy, chemical industry and road engineerings, its crusher chamber is made of a fixed tooth plate and a swing tooth plate, swing tooth plate is made periodic wobble to fixed tooth plate with 300 times frequency around hanging eccentric shaft, when swing tooth plate left fixed tooth plate, the material that has been broken just moved down under the use of gravity.The production efficiency of this disintegrating machine is low, the power consumption height, and the tooth plate quick abrasion is short service life, broken hard material difficulty.

The utility model provides a kind of production efficiency height at the shortcoming of above-mentioned existence, and breaking capacity is strong, the disintegrating machine that power consumption is low.

Technical essential of the present utility model is: it is made up of breaker, transmission device, safeties and frame etc.Breaker comprises eccentric shaft, bracket, moving jaw, tooth plate.Two moving jaws are suspended on separately the eccentric shaft accordingly, form quadric chain with bracket, constitute coarse crushing section a1, in two tooth plates of broken section a2, in small, broken bits section a3 be separately fixed on two moving jaws, tooth plate is done corresponding synchronously swing around eccentric shaft separately together with moving jaw, the formed crusher chamber of two tooth plates be divided into top coarse crushing section, in small, broken bits section of broken section and bottom.The bracket of thin-walled drum-type structure and the drive line angle of moving jaw are positive 60 degree, the positive rake supporting construction, and the fixed support point is located on the crossbeam of frame.Transmission device comprises big grooved wheel of a flywheel and two helical gears, constitutes the rigidity transmission of power, and two eccentric shafts are rotated synchronously, two moving jaws and the corresponding synchronously swing of tooth plate thereof, thus constitute three sections changable tooth angle crusher chamber of a symmetry, help the material fragmentation.Safeties are that thin-walled drum-shape bracket is met the over burdening extruding off-load protection machine that himself breaks rapidly and is not damaged, and frame adopts the sheet material Welding Structure.

The utility model can obtain the bigger ratio of reduction owing to adopted the crusher chamber of three sections symmetrical changable tooth angles, makes production efficiency improve three sesquialters, and breaking capacity is strong, product granularity is good, the tooth plate light abrasion, and long service life, safe and reliable, have simple in structurely, easy accessibility for ease of maintenaince waits advantage.

Description of drawings:

Fig. 1 is a general structure schematic diagram of the present utility model;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is an outline drawing of the present utility model;

Fig. 4 is the side view of Fig. 3.

During the utility model work, two tooth plates (4) that are fixed on the moving jaw (5) are done corresponding synchronously swing around eccentric shaft (6) separately respectively, bracket (2) is positive 60 degree with the drive line angle of moving jaw (5), crossbeam (3) is a Welding Structure with frame (1), the tooth plate (4) of symmetry broken line shape structure can reverse end for end to use long service life.Thin-walled drum-shape bracket (2) is except that constituting four connecting rods with moving jaw (5), eccentric shaft (6) and frame (1); it itself is a reliable safety locking motion of sensitivity; when crusher chamber fall into can not be broken foreign matter the time, the off-load of self breaking rapidly when load is uprushed protection machine is not damaged.Transmission device constitutes first order belt drive by the small grooved wheel on big grooved wheel (8) and the motor shaft head, and it is second section positive drive that two helical gears (7) intermesh, and makes the machine even running.Frame (1) is the sheet material Welding Structure, makes it in light weight, the intensity height, and handling ease, smooth outer surface is neat.

The utility model is a high energy crusher, and moving jaw obtains huge kinetic energy in order to broken material when 500～1000 times/minute swing in high frequency, the effect of obtain high efficiency, economizing on electricity and consuming, fall wearing and tearing.
