Abstract

The invention provides a roller gear of a crusher, which comprises a roller body and a plurality of roller teeth on the periphery of the roller body, wherein the roller teeth comprise front-segment roller teeth and rear-segment roller teeth; the rear-segment roller teeth lean against the rear end of the front-segment roller teeth and are shorter than the front-segment roller teeth. The roller gear of the crusher not only can crush medium-hardness mixed materials, but also is optimized in structure, improved in efficiency of crushing and reinforced in integral structure; the wearing resistance is improved through a surface wearing layer, the service life is longer, and the maintenance cost is lower.

Description

A kind of crusher's rollers gear
Technical field
The present invention relates to a kind of crusher's rollers gear, particularly a kind of roller gear that can broken mixed material.
Background technology
The bi-fluted roller type disintegrating machine relies on the roller tooth extruding on counterrotating two rollers and shears the disintegrating apparatus of broken material while working.The technology of existing toothed roll crusher exists can not strictly control broken rear product granularity, broken rear product is crossed the shortcomings such as the shock loading that crushing quantity is large, body is subject to is large, crushing teeth is fragile, overall noise is large, maintenance capacity is large.In order to prevent that the hard materials such as weedtree in pan feeding, ironware, spoil, rock from damaging crushing teeth, tension spring is equipped with in crushing shell lower end at single roll crusher, Compress Spring is equipped with at two ends at double-geared roller crusher one breaker roll, purpose is to fall to cutting the throat crusher chamber crushing shell or stressed increase of discaling roll can not be broken the time when bulk materials or hard material, thereby Compress Spring increases the discharge of crusher chamber asks gap, in order to discharge hard thing.Then borrow the restoring force of spring to make movable crushing shell or discaling roll get back to original position.But at present increasing cement producing line need to carry out fragmentation by the mixed material of clay, red bauxite, sandstone and shale.Existing toothed roll crusher can't meet current requirement.
Summary of the invention
Goal of the invention: the present invention is directed to that prior art exists can't broken mixed material problem, provide a kind of sturdy and durable, roller gear that can broken mixed material.
Technical scheme: the invention provides a kind of crusher's rollers gear, the some roller teeth that comprise roller body and roller body surrounding, described roller tooth comprises: leading portion roller tooth and back segment roller tooth, and described back segment roller tooth relies on leading portion roller tooth rear end, and described back segment roller tooth height is lower than leading portion roller tooth.
Described back segment roller tooth height obtains highly low 15-30 millimeter than leading portion roller tooth.The design of this structure can make leading portion roller tooth intensity higher, can play the effect of addi-tional crusher simultaneously.
Described back segment roller tooth height is less than leading portion roller tooth.Thereby pressure when less topside area can increase fragmentation reduces broken strength, make machine reduce load.
Described leading portion roller front tooth part built-up welding TM55 wear resistance electrode alloy-layer, hardness 53-58HRC.During due to fragmentation, the front portion of leading portion roller tooth is main stress point, and this wearing layer can strengthen the hardness of this point, makes the comparatively hard material also can be by light fragmentation.And this wearing layer increased the rub proofness of roller tooth integral surface greatly, improved service life.
Operation principle: material advanced feed system and entered between two rollers, and roller roller tooth rotates relatively, and the extruding of roller tooth, shearing material, reach crushing effect.
Beneficial effect: the present invention compares with the conventional roll tooth, not only can broken mixed material, also optimized structure, and increased crushing efficiency, overall structure is strengthened.The wearing layer on surface has increased wearability, and the life-span in use is longer, and maintenance cost is lower.
the accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
The structural representation that Fig. 2 is the roller that is comprised of the present invention;
The schematic diagram that Fig. 3 is two roller cooperatings.
the specific embodiment:
Below in conjunction with accompanying drawing, technical scheme of the present invention is further explained.
As shown in Figure 1, the present invention is a kind of crusher's rollers gear, comprise roller body 1 and roller tooth 2, its central roll tooth 2 comprises leading portion roller tooth 3 and back segment roller tooth 4, and the anterior build-up wear-resistant alloy-layer of leading portion roller tooth 3, preferably adopt TM55 welding rod layer, hardness can reach 55HRC, wherein the anterior angle of leading portion roller tooth 3 is 75 °, and such roller tooth is sharper, cuts also more laborsaving.Leading portion roller tooth is main crushing teeth, is the main part of broken material; Back segment roller tooth is the addi-tional crusher tooth, and further attrition crushing material reduces the granularity of material, controls the grain shape of material, and back segment roller tooth also can play the effect of supporting leading portion roller tooth simultaneously, can improve greatly the intensity of roller tooth.
As shown in Figure 2, whole roller by several independently roller gear combine, the center superposition of each roller gear wherein, the angle of a leading portion roller tooth or back segment roller tooth staggers mutually between the roller tooth of roller gear, wherein the rod body directly is connected with the rod axle by expansion sleeve, simple in structure, reliable roller body is used the casting of ZG40Mn2 steel alloy, has intensity preferably.
As shown in Figure 3, two rollers rotate relatively, the staggered engagement of roller tooth, and the extrusion shearing material reaches crushing effect.
