Description

A kind of roll breaker fluted roller makes a concession resetting-mechanism

Technical field

It the utility model is related to disintegrating machine technical field, and in particular to a kind of roll breaker fluted roller makes a concession resetting-mechanism.

Background technology

Kibbler roll is the common equipment of field of cracking machine, and its operation principle is the tooth that one or two pair of surface is covered with tooth plate Roller relative motion, between broken material feeds discaling roll, material is crushed using the extruding force between discaling roll；It is applied to water Operation broken, in small, broken bits in multiple technical field medium hardness materials such as mud, chemical industry, electric power, metallurgy and building materials；It is mainly by roller The part such as wheel, disk roller spring bearing, compression and adjusting means and drive device forms, when the size and higher hardness of material It can prevent material from equipment is not run between being stuck in discaling roll by compressing the spacing between adjusting means two disk rollers of adjustment Even damage discaling roll, therefore would generally be in a set of retreating mechanism 102 of each self installation in the both ends of discaling roll 101 on roller tooth machine（Such as Fig. 1 institutes Show）；Retreating mechanism is horizontally disposed in the prior art, but this mechanism is higher to the size requirements of horizontal space, so as to cause brokenly Broken machine complete machine structure seems excessively too fat to move.

Publication No. CN101954302A Chinese utility model patent discloses a kind of roll-type on January 26th, 2011 and broken Broken machine automatic reset mechanism, including left and right revolving body, the left and right revolving body are respectively trapezoidal bearing block by cross section It is fixed on guide rail, the upper end of bearing block is fixed on upper rail by guider, and the lower end of bearing block is fixed on lower guideway, Symmetrically connected by pull bar and butterfly spring mechanism between the left and right bearing block, between the symmetrical butterfly spring mechanism Pass through safe pin connection.

Publication No. CN201067698Y Chinese utility model patent discloses a kind of roll-type on June 4th, 2008 and broken Broken machine spacing regulating mechanism, including movable axle bearing, guide rail, butterfly spring, push rod, baffle plate, guide rail, push rod, baffle plate difference It is fixedly connected in crusher frame, push rod withstands movable axle bearing side, and butterfly spring is two after plus certain precompression End is separately fixed on the opposite side and baffle plate of movable axle bearing, it is characterised in that the guide rail and the movable axle bearing Between be additionally provided with roller, the movable axle bearing is moved by roller on guide rail.

Although above-mentioned patent can solve the problems, such as the automatic yielding of kibbler roll, there is following lack in it Fall into：1st, because the diameter for the material that is broken is uneven, therefore the power that discaling roll is subject to is stirred, and easily causes broken machine vibration； 2nd, when between larger and harder large-sized fragment feeding discaling roll, it is desirable to the yielding stroke of disintegrating machine moving shaft holder compared with Greatly, but due to disk spring rigidity it is big the characteristics of, moving shaft holder move when by the disk spring of large deformation resistance it is larger, Therefore it is limited to make a concession stroke for it；3rd, it is larger when the hard thing of large scale is stuck between discaling roll because crusher axis span is larger Make a concession resistance to be attached in moving axis bearing, to roll shaft is made by larger additional bending moment, easily cause tooth plate fracture, roll shaft to produce serious Expendable deformation etc. causes mechanical breakdown, has a strong impact on that the disintegrating machine life-span brings potential safety hazard；4th, disk spring pressure and height The ratio that degree accounts for free height is great, and it is longer to combine the total length of disk spring, and it is too fat to move to easily cause structure, makes this mechanism not allow to push away It is wide to use.

The content of the invention
