A flywheel and an insurance disk are sleeved at the outer end of the roll shaft of each toothed roll. A feed hopper and a discharge hopper are arranged on the rack. Each toothed roll comprises a roll body, column teeth and screws. A plurality of step-type installing grooves are arranged on the surface of each roll body and distributed along the circumferential direction of the roll body. The groove face of each installing groove is respectively and axially provided with a row of column tooth holes and a row of screw holes. Each column tooth comprises a column body; the upper portion of the column body extends to form a protection table; one side of the protection table is provided with an installing table; and a U-shaped step hole is arranged on the installing table. The column teeth are arranged in the corresponding column tooth holes of the roller bodies, and the screws are sequentially arranged in the U-shaped step holes and the screw holes to lock the column teeth. The toothed roll crusher has the advantages of enabling products to be even in particle, being small in the amount of over crushing, high in crushing efficiency, small in amount of dust and consumed precious metal, and low in cost, thoroughly solving the problem of repairing of broken teeth, achieving equipment overload protection, and greatly reducing cost of running and maintaining of equipment.

Description

A kind of toothed roll crusher

Technical field

The utility model relates to a kind of disintegrating machine for broken mineral products, 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 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.

The patent No. of application was the toothed roll crusher patent of ZL201020628553.9 on November 26th, 2010, although solved the root problem of disintegrating machine, the manufacture craft more complicated, cost is higher.

Summary of the invention

The technical problems to be solved in the utility model is: overcome the defective of prior art, provide a kind of and produce that crushing efficiency is high, 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.

In order to solve the problems of the technologies described above, the utility model proposes following technical scheme: a kind of toothed roll crusher, include frame, one group of discaling roll that is complementary is installed on the frame, this discaling roll comprises a roll shaft, and the roll shaft outer end of each discaling roll 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, and the below that is positioned at discaling roll engagement position is provided with discharge bucket;

This discaling roll includes roll body, post tooth and screw;

This roll body surface has the mounting groove of some steps, and mounting groove distributes along the circumferencial direction of roll body, is provided with vertically respectively an organ timbering perforation and row's screw hole on the groove face of every mounting groove, and 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-shaped stepped hole on the erecting bed; After the post tooth was packed in post perforation corresponding to roll body, screw was packed in U-shaped stepped hole and the screw hole successively with the locking of post tooth, and the head of screw is pressed on the step surface of U-shaped stepped hole; Stagger vertically mutually in the post tooth position of two discaling rolls;

Be provided with telophragma between described flywheel and the safety disk, this telophragma is sleeved on the roll shaft and is bolted on the outer face of flywheel, is connected by 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.

The further restriction of technique scheme is: described flywheel rotates by band transmission control respectively.

The utility model has the advantages that:

1, the utility model has changed the structure of discaling roll in the prior art, and its purpose is: 1, post tooth top extend to arrange protects platform, has protected roll surface, has increased the protection of pair roller surface; 2, U-shaped 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.

2, the utility model is provided with telophragma between safety disk and flywheel, is connected by 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 excessive and have foreign matter constantly when the ore that adds, the insurance pin can disconnect, and makes flywheel separate the discaling roll stall with the transferring power between the discaling roll axle.So, can effectively prevent apparatus overload, guarantee service life of the present utility model.

3, owing to after the disconnection of insurance pin, only need to again change pin and getting final product, the cost that expends is lower.

4, 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 maintenance cost of equipment.
