Abstract
The invention provides a kind of Roller gear of crusher, comprise some roller teeth of 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.The present invention not only can broken medium-hard mixed material, also optimizes structure, adds crushing efficiency, overall structure is strengthened.The wearing layer on surface adds wearability, and the life-span is in use longer, and maintenance cost is lower.
Description
Technical field
The present invention relates to a kind of Roller gear of crusher, particularly a kind of can the roller gear of broken mixed material.
Background technology
The roller tooth on two rollers relatively rotated is relied on to extrude and shear the disintegrating apparatus of broken material during the work of bi-fluted roller type disintegrating machine.The technology of existing toothed roll crusher exists strictly can not control broken rear product granularity, broken rear product crosses the shortcomings such as the shock loading that crushing quantity is large, body is subject to is comparatively large, crushing teeth is fragile, overall noise is large, maintenance capacity is large.Crushing teeth is damaged in order to prevent the hard material such as weedtree, ironware, spoil, rock in pan feeding, in the crushing shell lower end of single roll crusher, tension spring is housed, at the two ends of double-geared roller crusher one breaker roll, Compress Spring is housed, object is when bulk materials or hard material fall to cutting the throat crushing shell or discaling roll stressed increase when crusher chamber can not be broken, thus the discharge that Compress Spring increases crusher chamber asks gap, to discharge hard object.Then the restoring force of spring is borrowed to make movable crushing shell or discaling roll get back to original position.But increasing cement producing line needs the mixed material of clay, red bauxite, sandstone and shale to carry out fragmentation at present.Existing toothed roll crusher cannot meet Current demands.
Summary of the invention
Goal of the invention: what the present invention is directed to that prior art exists cannot the problem of broken mixed material, provides a kind of sturdy and durable, can the roller gear of broken mixed material.
Technical scheme: the invention provides a kind of Roller gear of crusher, comprise some roller teeth of 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.Pressure when less topside area can increase fragmentation thus reduce broken strength, makes machine reduce load.
Described leading portion roller front tooth part built-up welding TM55 wear resistance electrode alloy-layer, hardness 53-58HRC.Because during fragmentation, the front portion of leading portion roller tooth is main stress point, this wearing layer can strengthen the hardness of this point, makes comparatively hard material also can by light fragmentation.And this wearing layer considerably increases the rub proofness of roller tooth integral surface, improves service life.
Operation principle: material entered feed system and enters between two rollers, and roller roller tooth rotates relatively, the extruding of roller tooth, shearing material, reach crushing effect.
Beneficial effect: the present invention, not only can broken mixed material compared with conventional roll tooth, also optimizes structure, adds crushing efficiency, overall structure is strengthened.The wearing layer on surface adds wearability, and the life-span is in use longer, and maintenance cost is lower.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of the roller be made up of the present invention;
Fig. 3 is the schematic diagram of two roller cooperatings.
detailed description of the invention:
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 Roller gear of crusher, 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, the anterior build-up wear-resistant alloy-layer of leading portion roller tooth 3, preferably adopts 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 addi-tional crusher tooth, 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 supporting leading portion roller tooth simultaneously, can improve the intensity of roller tooth greatly.
As shown in Figure 2, whole roller by several independently roller gear combine, the wherein center superposition of each roller gear, stagger mutually between the roller tooth of roller gear the angle of a leading portion roller tooth or back segment roller tooth, wherein rod body is directly connected with rod axle by expansion sleeve, simple, the reliable roller body of structure uses the casting of ZG40Mn2 steel alloy, has good intensity.
As shown in Figure 3, two rollers rotate relatively, and the staggered engagement of roller tooth, extrusion shearing material reaches crushing effect.
