Abstract

The utility model discloses a tooth roller of a crushing machine. The tooth roller comprises a plurality of roll shafts rotatably arranged inside a housing of the crushing machine, wherein the roll shafts are arranged in parallel; the outer circular surfaces of the roll shafts are respectively provided with a plurality of rows of tooth handle holes parallel to the axis along the peripheral direction; the tooth roller comprises a plurality of roller teeth; each roller tooth comprises a protecting table and a tooth handle integrally connected with the bottom end of the protecting table; the tooth handles of the roller teeth are correspondingly inserted in the plurality of rows of tooth handle holes which are parallel to the axis and formed in the roll shafts respectively; a plurality of column teeth and shearing blades are distributed on the upper surfaces of the protecting tables of the roller teeth at intervals along the peripheral direction of the roller shafts; in the roll shafts, the column teeth on the outer circular surfaces of the corresponding roll teeth on two adjacent roll shafts are mutually staggered. According to the tooth roller, the crushing efficiency and fine crushing degree and uniformity of products are improved, so that product grains are uniform, and the effects of being low in power consumption, high in yield, high in crushing efficiency, stable to operate, small in noise and little in dust are achieved; the machining technology is simplified through plug-in mounting of the roller teeth, and the tooth roller is convenient to mount, adjust and maintain.

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, is mainly 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 is also 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, 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 still there is complex structure in old-fashioned " toothed roll crusher ", consumes 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 toothed roll crusher patent that the patent No. is ZL201020625553.9, although solved the root problem of disintegrating machine, the manufacture craft more complicated, cost is higher.And there is no shear blade on the roller tooth of existing cracker teeth roller, thereby percentage of damage is relatively low.

The utility model content

The utility model purpose 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, easy care simple in structure, manufacture simple cracker teeth roller.

The utility model is achieved through the following technical solutions:

A kind of cracker teeth roller, include a plurality of roll shafts that are rotatably installed in crusher shell, described a plurality of roll shaft is arranged side by side, it is characterized in that: along the circumferential direction be respectively equipped with many rows tooth delthyrium parallel with axis on the periphery of described a plurality of roll shafts, include a plurality of roller teeth, described a plurality of roller tooth includes respectively and protects the tooth handle that platform and one are connected to the Hu Tai bottom, the tooth handle of a plurality of roller teeth is corresponding being inserted in many rows on described a plurality of roll shaft tooth delthyrium parallel with axis respectively, the upper surface that protects platform of a plurality of roller teeth is intervally distributed with a plurality of post teeth and shear blade along the circumferencial direction of the roll shaft at place, in described a plurality of roll shaft, a plurality of post teeth on adjacent two roll shafts on corresponding roller tooth periphery stagger mutually.

Described a kind of cracker teeth roller is characterized in that: described arrange between the tooth delthyrium parallel with axis is respectively equipped with screw hole more.

Described a kind of cracker teeth roller is characterized in that: the both sides of protecting platform of described a plurality of roller teeth have the U-shaped stepped hole.

Described a kind of cracker teeth roller is characterized in that: in described a plurality of roll shafts, form in twos one group.

During use, power-on, slow down and transmission device makes two roll shafts do to rotate in opposite directions.Add ore from top, post tooth and shear blade are carried out splitting and shearing-crushing to ore equably, and lump ore is broken into to qualified particle.

The utility model has changed the structure of discaling roll in the prior art, and its purpose is: 1, between adjacent post tooth, along the circumferential direction be provided with shear blade, improved widely degree in small, broken bits and the uniformity of crushing efficiency and product; 2, along the circumferential direction be provided with many rows tooth delthyrium parallel with axis on the roll shaft periphery, arrange in the tooth delthyrium parallel with axis is fitted with respectively the roller tooth more, simplified processing technology, reduced production cost, facilitated simultaneously and installed and maintenance, time saving and energy saving.

The utility model has the advantages that:

Along the circumferential direction be provided with shear blade between the adjacent post tooth of the utility model in every organ timbering 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; The roller tooth is inserted in the tooth delthyrium on roll shaft by tooth handle correspondence, has simplified processing technology, and installation, adjustment and easy to maintenance.
