Abstract

The invention discloses a crusher tooth roller with arc toothed plates, which comprises a plurality of roller shafts rotationally mounted in a crusher housing, wherein a plurality of axial key grooves are formed in the external arc surface of each of the roller shafts in a peripheral direction respectively; a plurality of arc toothed plates are fixedly mounted on the external arc surface of each of the roller shafts respectively; positioning key grooves corresponding to the axial key grooves one to one are formed in the internal arc surface of each arc toothed plate; flat keys are mounted between the corresponding axial key grooves and the positioning key grooves; a plurality of rows of columnar tooth heads integrally connected are arranged on the external arc surfaces of the arc toothed plates in the peripheral direction; shearing blades integrally connected are arranged between the adjacent columnar tooth heads in each row of columnar tooth heads in the peripheral direction; and the rows of columnar tooth heads on the corresponding arc toothed plates on the two adjacent roller shafts in the roller shafts are staggered. The roller greatly improves the crushing efficiency, as well as fineness and uniformity of a product, simplifies a processing technology and is convenient to mount and maintain.

Description

Cracker teeth roller with arc tooth plate
Technical field
The present invention relates to the toothed roll crusher field of mineral products fragmentation, specifically a kind of cracker teeth roller with arc tooth plate.
Background technology
Along with China's rapid development of economy, capital construction is in large scale.To the demand of construction material, will be surprising.China is also a mineral products demand big country simultaneously.Mineral products processing market prospects are wide.At present in China and even abroad, the broken process equipment of mineral products always in poor efficiency, high energy consumption, highly wear and tear, hover in " one is low " of high pollution, " three height ".As " hammer mill ", " impact breaker ", be that match power is large, wear and tear in machines is large, efficiency is low, noise is high, dust pollution is serious always.And old-fashioned " toothed roll crusher " still exist complex structure, consume that noble metal is many, maintenance cost is high, use defects such as adjusting complexity, be difficult to apply always.The disintegrating apparatus of developing a kind of " high efficiency ", " low energy consumption ", " low noise ", " dust pollution is little " has been extremely urgent.The patent No. is the toothed roll crusher patent of ZL206020627773.9, although solved the root problem of disintegrating machine, manufacture craft more complicated, cost is higher.And the roller between cog of the existing cracker teeth roller with arc tooth plate does not have shear blade, thereby percentage of damage is relatively low.
Summary of the invention
The object of the invention is exactly in order to make up the defect of prior art, provide a kind of crushing efficiency high, consume energy low, noise is low, dust pollution is little, consume that noble metal is few, equipment attrition is little, the cracker teeth roller with arc tooth plate of easy care simple in structure.
The present invention is achieved by the following technical solutions:
A kind of cracker teeth roller with arc tooth plate, include a plurality of roll shafts that are rotatably installed in crusher shell, described a plurality of roll shafts are arranged side by side, it is characterized in that: on the exterior arc surface of described a plurality of roll shafts, be along the circumferential direction respectively equipped with a plurality of axial keyways, on the exterior arc surface of described a plurality of roll shafts, be installed with respectively a plurality of arc tooth plates, on the inner arc surface of each arc tooth plate, be respectively equipped with and a plurality of axial keyways positioning spline one to one, between corresponding axial keyway and positioning spline, be separately installed with flat key; On the exterior arc surface of described a plurality of arc tooth plates, along the circumferential direction there is respectively many rows columnar tooth head that one connects, in every row's columnar tooth head, between adjacent columnar tooth head, along the circumferential direction there is respectively the shear blade that one connects; In described a plurality of roll shaft, the many rows columnar tooth head on adjacent two roll shafts on corresponding arc tooth plate staggers mutually.
Described a kind of cracker teeth roller with arc tooth plate, is characterized in that: in described a plurality of roll shafts, form between two one group.
The described cracker teeth roller with arc tooth plate, it is characterized in that: on the exterior arc surface of described a plurality of roll shafts, along the circumferential direction the both sides at each axial keyway are respectively equipped with screw hole, on described a plurality of arc tooth plate, along the circumferential direction in the both sides of positioning spline, be respectively equipped with and described screw hole installing hole one to one, there is screw pass described installing hole and be screwed in screw hole corresponding thereto, described a plurality of arc tooth plates are fixedly mounted on respectively on the exterior arc surface of a plurality of roll shafts.
During use, power-on, slows down and transmission device makes two roll shafts do to rotate in opposite directions.From top, add ore, columnar tooth head and shear blade are carried out splitting and shearing-crushing to ore equably, and lump ore is broken into qualified particle.
The present invention has changed the structure of discaling roll in prior art, and its object is: 1, in every row's columnar tooth head, between adjacent columnar tooth head, be along the circumferential direction provided with shear blade, improved widely degree in small, broken bits and the uniformity of crushing efficiency and product; 2, on a plurality of axial keyways that are along the circumferential direction provided with on roll shaft exterior arc surface and the inner arc surface of arc tooth plate, be respectively equipped with and a plurality of axial keyways positioning spline one to one, between corresponding axial keyway and positioning spline, be separately installed with flat key, arc tooth plate is positioned on roll shaft exterior arc surface, simplified processing technology, reduced production cost, facilitated simultaneously and installed and maintenance, time saving and energy saving.
Advantage of the present invention is:
Between the adjacent columnar tooth head of the present invention in every row's columnar tooth head, be along the circumferential direction provided with shear blade, degree in small, broken bits and the uniformity of crushing efficiency and product have greatly been improved, can make product seed even, energy consumption is low, production capacity is high, crushing efficiency is high, operate steadily, noise is little, dust is few; Arc tooth plate is connected and is positioned on roll shaft exterior arc surface by key, has simplified processing technology, installation, adjustment, easy to maintenance.
