Abstract
The utility model discloses a novel breaker pinion rack, the main connecting plate outside is equipped with even parallel distribution's dovetail, and the inside plug bush of dovetail has the lower part to be the dogtooth strip of swallow tail, and the outside of dogtooth strip is equipped with tooth base face and the contact of main connecting plate, and the top of dogtooth strip is equipped with the dogtooth head, the dogtooth strip is and is the bending to direction of rotation, and the narrower one side of dogtooth strip curved surface is the interior flank of tooth, and the one side of dogtooth strip curved surface broad is the outer flank of tooth, and the middle part of the outer flank of tooth is equipped with vice dogtooth strip. The utility model discloses it is efficient to arrange the material, and crushing effect is good, changes the convenient and long service life of dogtooth strip.
Description
Technical field
This utility model relates to disintegrating apparatus field, is specifically related to a kind of new type crushing machine tooth plate.
Background technology
The discharge of existing crusher toothed plate is inefficient, thus have impact on the work efficiency of disintegrating machine. Additionally, existing crusher toothed plate is generally adopted the casting of ZGMn13 potassium steel, there is good abrasion resistance and certain impact flexibility. The impact flexibility of ZGMn13 Hadfield steel is significantly high, and up to 200J/cm2, original hardness is less than HB230, but under high impact load, working surface can produce hardening effect, and case hardness is up to HRC42-48, and center still keeps good toughness. But, operationally, if impact energy is inadequate, ZGMn13 austenitic surface shock hardening can not fully produce, and potassium steel surface does not reach high rigidity, and now, the work double wedge of tooth plate will soon be worn, and service life is shorter.
Utility model content
The purpose of this utility model is the shortcoming and defect in order to overcome prior art, it is provided that discharge efficiency is high, and crushing effect is good, changes a kind of new type crushing machine tooth plate of convex tooth strips convenience and long service life.
A kind of new type crushing machine tooth plate, it is made up of main connecting plate and convex tooth strips, the dovetail groove of uniform parallel distribution it is provided with outside described main connecting plate, the convex tooth strips that bottom is dovetail it is inserted with inside described dovetail groove, the tooth basal plane that is provided externally with of described convex tooth strips contacts with main connecting plate, and the top of convex tooth strips is provided with double wedge head; Described convex tooth strips is in for bending to direction of rotation, and the narrower one side of convex tooth strips curved surface is inner toothed surface, and the wider one side of convex tooth strips curved surface is the outer flank of tooth, and the middle part of the described outer flank of tooth is provided with secondary convex tooth strips.
Further, described double wedge head is arc.
Further, described dovetail is equal with tooth base width.
Further, the height of described convex tooth strips is 1.2 times of width.
The beneficial effects of the utility model are:
1. convex tooth strips is in for bending to direction of rotation, during work, it is possible to be pressed down against rapidly discharge, improves the discharge efficiency of tooth plate, thus improve the work efficiency of disintegrating machine;
2. the middle part of the outer flank of tooth is provided with secondary convex tooth strips, and double wedge head is arc, enhances crushing effect.
3. convex tooth strips is connected by dovetail groove and dovetail with main connecting plate, and both conveniently replaced damaged convex tooth strips, while meeting job requirement, can increase the service life again;
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing: 1, main connecting plate, 11, dovetail groove, 2, convex tooth strips, 201, dovetail, 202, secondary convex tooth strips, 211, double wedge head, 221, tooth basal plane, 222, inner toothed surface, 223, the outer flank of tooth.
Detailed description of the invention
Below in conjunction with embodiment, detailed description of the invention of the present utility model is described in further detail:
As shown in Figure 1, a kind of new type crushing machine tooth plate, it is made up of main connecting plate 1 and convex tooth strips 2, being provided with the dovetail groove 11 of uniform parallel distribution outside main connecting plate 1, dovetail groove 11 is internal is inserted with the convex tooth strips 2 that bottom is dovetail 201, and the tooth basal plane 221 that is provided externally with of convex tooth strips 2 contacts with main connecting plate 1, dovetail 201 is equal with tooth basal plane 221 width, the top of convex tooth strips 2 is provided with double wedge head 211, and double wedge head 211 is arc, and the height of convex tooth strips 2 is 1.2 times of width; Convex tooth strips 2 is in for bending to direction of rotation, and the narrower one side of convex tooth strips 2 curved surface is inner toothed surface 222, and the wider one side of convex tooth strips 2 curved surface is the outer flank of tooth 223, and the middle part of the outer flank of tooth 223 is provided with secondary convex tooth strips 202.
The above is only preferred implementation of the present utility model; should be understood that; for the person of ordinary skill of the art; under the premise without departing from this utility model know-why; can also making some improvements and modifications, these improvements and modifications should also be as being considered as within protection domain of the present utility model.
