Description

A kind of toothed roll crusher

Technical field:

The utility model relates generally to a kind of broken disintegrating machine of mineral products that is used for, and relates in particular to a kind of toothed roll crusher.

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 has a extensive future.At present and even abroad, in China 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 ".Like " hammer mill ", " impact breaker ", be that match power is big, wear and tear in machines is big, 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 complicacy, 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, though solved the root problem of disintegrating machine, the manufacture craft more complicated, cost is higher.

The utility model content:

The utility model purpose is exactly in order to remedy the defective of prior art, provides a kind of and produces the crushing efficiency height, power consumption is low, noise is low, dust pollution is little, consume that noble metal is few, equipment attrition is little, the disintegrating machine of easy care simple in structure.

The utility model is realized through following technical scheme:

A kind of toothed roll crusher includes frame, and one group of discaling roll that is complementary is installed on the frame, and the roll shaft outer end of each discaling roll all is set with flywheel and safety disk; The top that is positioned at discaling roll engagement position on the frame is provided with feed hopper; The below that is positioned at discaling roll engagement position is provided with discharge bucket; It is characterized in that: discaling roll includes roll body, post tooth and screw, and the roll body surface has the mounting groove of some steps, and mounting groove distributes along the circumferencial direction of roll body; Be provided with an organ timbering perforation and row's screw hole on the groove face of every mounting groove respectively vertically, post perforation and screw hole are corresponding one by one; The post tooth includes cylinder, extend to be provided with and protect platform in cylinder top, and a wherein side of protecting platform is made as erecting bed, has U type stepped hole on the erecting bed; After the post tooth was packed in the corresponding post perforation of roll body, screw was packed into successively and the post tooth is locked in U type stepped hole and the screw hole, and the head of screw is pressed on the step surface of U type stepped hole; Stagger vertically each other in the post tooth position of two discaling rolls.

A kind of toothed roll crusher is characterized in that: have the telophragma gap to be sleeved on the roll shaft between said flywheel and the safety disk, and through on the outer face that is bolted to flywheel, be connected through the insurance pin between safety disk and the telophragma; Have the connecting hole of mutual correspondence on described telophragma and the safety disk; Described insurance pin two ends are plugged in respectively in the connecting hole corresponding on telophragma and the safety disk, and the position on the annular outer wall of insurance pin between telophragma and safety disk is provided with cannelure.Connect through key between safety disk and the roll shaft.

A kind of toothed roll crusher is characterized in that: said flywheel rotates through band transmission control respectively.

The structure that realizes the band transmission includes motor, and the output shaft outer end of motor is set with driving wheel, is set with belt between the flywheel of driving wheel and correspondence.

During use, power-on, two motors rotate in opposite directions, make two discaling rolls do to rotate in opposite directions.Add ore from the feed hopper position, gear hobbing is carried out the splitting fragmentation to ore equably, and lump ore is broken for qualified particle.Particle falls into discharge bucket.

The utility model has changed the structure of discaling roll in the prior art, and its purpose is: 1, post tooth top extend to be provided with protects platform, has protected roll surface, has increased the protection of pair roller surface; 2, U type installing hole has been simplified processing and installed, and is time saving and energy saving; 3, the application of safety disk has significantly reduced equipment manufacturing cost and maintenance cost.

The utility model is provided with telophragma between safety disk and flywheel, is connected through the insurance pin between safety disk and the telophragma, insures on the annular outer wall of pin that the position is provided with cannelure between telophragma and safety disk.So, when the ore that adds excessive with have foreign matter constantly, the insurance pin can break off, and makes flywheel separate the discaling roll stall with the transferring power between the discaling roll axle.So, can effectively prevent apparatus overload, guarantee the service life of the utility model.

Because after the insurance pin breaks off, only need change pin again and get final product, the cost that expends is lower.

The utility model has the advantages that:

The utility model not only can make the product seed evenly, cross that crushing is few, energy consumption is low, production capacity is high, crushing efficiency is high, operate steadily, noise is little, dust is few.And it is low to consume the few cost of noble metal, adjusts easy to maintenance.Particularly thoroughly solve broken teeth and repaired problem, realized the overload protection of equipment, greatly reduced the operation and the maintenance cost of equipment.
