Abstract

The utility model discloses a jaw crusher which is the improvement for the 400*600 type crusher. The improved part comprises the strucutre that an integral movable jaw is thickened; a movable jaw hole is enlarged; the eccentric distance of an eccentric shaft is enlarged; guard plates of the upper edge and the lower edge can be changed into the symmetrical shape; a toggle plate pad can be changed into the cambered shape; a sizing block can be added between an adjusting seat and an ear seat; a draw rod is arranged at the lower end of the movable jaw; the lower end of a fixed jaw plate is lengthened. The service life of the crusher can extend after the improvement, and the utility model can enhance the crushing efficiency.

Description

Jaw crusher

The utility model is the improvement to jaw crusher, mainly is to be the improvement of 400 * 600 jaw crusher to model.

The model of current use is that 400 * 600 jaw crusher exists many problems, mainly is that bearing is short service life, moving jaw frangibility, following backplate is easy to wear and change frequent, after the ear seat wearing and tearing of frame whole frame is scrapped, crushing efficiency is low, and pull bar is fragile etc.

The purpose of this utility model is exactly that a kind of jaw crusher is provided in order to overcome the deficiencies in the prior art.

The purpose of this utility model can realize by following measure:

The primary structure of this disintegrating machine is a setting-up eccentricity axle on the frame, and an end of axle is installed flywheel, and the other end is installed belt pulley, belt pulley connects motor, and the eccentric part of axle is installed rolling bearing, and rolling bearing drives moving jaw, the positive sewing jaw of installing of moving jaw, there is the bracket pad at the moving jaw back side, and bracket one end is in the bracket pad, and the bracket other end is in adjusting seat, adjusting seat is installed in the ear seat slideway of frame, adjust the seat back and connect trimmer, trimmer connects the adjustment leading screw, adjusts leading screw and is installed on the frame by screw.Pull bar one termination is moved jaw, and the other end frame of meeting sb. at the airport has spring on the pull bar.The moving relatively jaw of fixed jaw is installed on the frame.The both sides of fixed jaw and sewing jaw are upper and lower limit backplates.Concrete improvement part is: the eccentric throw of a, eccentric shaft (8) is the 10-13 millimeter.The race diameter of b, rolling bearing (7) is 400 millimeters.The following backplate (19) that c, top backplate (3) connect is the trapezoidal of symmetry.D, the bracket pad (18) that contacts with bracket (17) are the garden arc, and its another side is trapezoidal.Between e, adjustment seat (15) and the ear seat (10) parallels (9) is arranged.F, pull bar (16) are pulled in the lower end of moving jaw (5).Align with sewing jaw (4) lower end in g, fixed jaw (2) lower end.H, moving jaw (5) thickness is 240 ± 20 millimeters.

Description of drawings:

Fig. 1 is a general illustration of the present utility model, (1) frame wherein, (2) fixed jaw, (3) top backplate, (4) sewing jaw, (5) move jaw, (6) flywheel, (7) rolling bearing, (8) eccentric shaft, (9) parallels, (10) ear seat, (11) adjust pad, (12) screw, (13) adjust leading screw, (14) spring, (15) adjust seat, (16) pull bar, (17) bracket, (18) bracket pad, (19) following backplate.

Fig. 2 is that the bracket pad is not intended to and cutaway view among Fig. 1.

Fig. 3 is a parallels schematic diagram among Fig. 1.

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

Fig. 5 is a following backplate schematic diagram among Fig. 1.

The utlity model has following advantage;

1, complete machine improves 3 times service life.

2, broken work efficiency improves 2 times.

3, structure is more reasonable.

Below the utility model is described further:

This machine is to be the improvement of 400 * 600 disintegrating machine to model, has mainly improved following position:

1, the whole thickening of moving jaw increases to 240 ± 20 millimeters by original 160-170 millimeter, has overcome the easily broken problem of moving jaw.

2, moving jaw hole is strengthened, and is changed into by original use 3538 bearings and uses 3638 bearings, makes bearing life improve 3 times.

3, the eccentric throw of eccentric shaft becomes big, makes jaw activity quantitative change big, improves work efficiency.

4, to change symmetry into by original asymmetric shape trapezoidal for upper and lower limit backplate, like this can right and left mutually changing after backplate weares and teares, and the life-span is doubled.

5, the bracket pad is by the original trapezoidal arc that changes into, and it is more reasonable that bracket is contacted with the bracket pad.

6, be added with parallels adjusting between seat and the ear seat, after parallels weares and teares, can change, avoided the shortcoming that whole frame is scrapped behind the original wearing and tearing ear seat.

7, pull bar was changed into and is pulled in moving jaw lower end by being pulled in moving jaw middle part originally, increases of exerting all one's strength overcome original pull bar owing to the stressed excessive and shortcoming that often fractures.

8, fixed jaw lower end lengthening, make fixed jaw the same with the lower end of sewing jaw long, the phenomenon of the material extrusion that makes progress when having overcome original particle like this makes 2 times of percentage of damage raisings.
