Abstract

The utility model discloses a pin roll of a crusher, which comprises a plurality of roll shafts mounted inside the casing of the crusher in a rotating manner, wherein the roll shafts are arranged side by side, a plurality of toothed rings are sleeved on the roll shafts, a plurality of columnar teeth are arranged on the external circular surfaces of the toothed rings, and a cutting blade is fixed between every two adjacent columnar teeth; and the columnar teeth on the external circular surfaces of the corresponding toothed rings on two adjacent roll shafts are arranged in a staggered manner. In the utility model, the cutting blade is arranged between every two columnar teeth in the circumferential direction, the efficiency of crushing and the fine crushing degree and the uniformity of product are improved greatly, less energy is consumed, the productivity is high, the crushing efficiency is high, the running is stable, the noise is low, and the dust is less.

Description

Cracker teeth roller
Technical field:
The utility model relates generally to the disintegrating machine of mineral products fragmentation, relates in particular to toothed roll crusher, mainly is a kind of cracker teeth roller.
Background technology:
Along with China's rapid development of economy, capital construction is in large scale.Demand to construction material will be surprising.China also is a mineral products demand big country simultaneously.The 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, pace up and down in " one is low " of high pollution, " three height ".Such as " hammer mill ", " impact breaker ", be that match power is large, wear and tear in machines is large, efficient is low, noise is high, dust pollution is serious always.And still there is complex structure in old-fashioned " toothed roll crusher ", consumes that noble metal is many, maintenance cost is high, use defectives such as adjusting complexity, is 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.(I am the toothed roll crusher patent of ZL201020628553.9 in the patent No. of application on November 26th, 2010, although solved the root problem of disintegrating machine, the manufacture craft more complicated, cost is higher.) and the ring gear of existing cracker teeth roller on do not have shear blade, thereby percentage of damage is relatively low.
The utility model content:
The utility model purpose is exactly in order to remedy the defective of prior art, provides that a kind of crushing efficiency is high, power consumption is low, noise is low, dust pollution is little, consumes that noble metal is few, equipment attrition is little, the cracker teeth roller of easy care simple in structure.
The utility model is achieved through the following technical solutions:
A kind of cracker teeth roller, include and rotate a plurality of roll shafts of installing in the crusher shell, a plurality of roll shafts are arranged side by side, described roll shaft is set with a plurality of ring gears outward, it is characterized in that: be provided with in the circumferential direction of the circle a plurality of columnar tooths on the periphery of described ring gear, be provided with in the circumferential direction of the circle shear blade between the adjacent columnar tooth; Columnar tooth on described adjacent two roll shafts on the corresponding ring gear periphery mutually staggers and arranges.
The two ends of described roll shaft are separately installed with locking nut, and described locking nut is locked at a plurality of ring gears on the roll shaft.
Described roll shaft has two, and two roll shafts form one group.
During use, power-on is slowed down and transmission device makes two roll shafts do to rotate in opposite directions.Add ore from top, columnar tooth and shear blade are carried out splitting and shearing-crushing to ore equably, with the broken qualified particle of lump ore.
The utility model has changed the structure of discaling roll in the prior art, and its purpose is: 1, be provided with in the circumferential direction of the circle shear blade between the columnar tooth, improved widely degree in small, broken bits and the uniformity of crushing efficiency and product; 2, roll shaft adopts ring gear string dress to simplify processing technology outward, has reduced production cost; Made things convenient for simultaneously and installed and maintenance, time saving and energy saving.
The utility model has the advantages that:
The utility model is provided with shear blade in the circumferential direction of the circle between columnar tooth, degree in small, broken bits and the uniformity of crushing efficiency and product have greatly been improved, can make the product seed even, energy consumption is low, production capacity is high, crushing efficiency is high, operate steadily, noise is little, dust is few, and processing technology, installation, adjustment, easy to maintenance have been simplified.
Description of drawings:
Fig. 1 is front view of the present utility model.
Fig. 2 is the structural representation of ring gear in the utility model.
Fig. 3 is the cutaway view of ring gear in the utility model.
The specific embodiment:
Referring to Fig. 1,2,3, a kind of cracker teeth roller, include and rotate a plurality of roll shafts 1 of installing in the crusher shell, a plurality of roll shafts 1 are arranged side by side, be set with a plurality of ring gears 2 outside the described roll shaft 1, be provided with in the circumferential direction of the circle a plurality of columnar tooths 3 on the periphery of described ring gear 2, be provided with in the circumferential direction of the circle shear blade 4 between the adjacent columnar tooth 3; Columnar tooth 3 on described adjacent two roll shafts 1 on the corresponding ring gear periphery is staggered and arranges.
The two ends of described roll shaft 1 are separately installed with locking nut 5, and described locking nut 5 is locked at a plurality of ring gears 2 on the roll shaft.
Described roll shaft 1 has two, and two roll shafts 1 form one group.
