Technical field
The utility model relates to the Mechanical Crushing field, relates in particular to a kind of broken high frequency quartering hammer of engineering that is used for.
Background technology
Quartering hammer is that collection mechanical-hydraulic mechanics and data signal, digital monitoring are the physics disintegrating apparatus of one, and the cutter tooth of quartering hammer can produce impulsive force to object under the effect of vibrator, and then realizes broken.General quartering hammer is to drive eccentric wheel by hydraulic motor to rotate; And then producing centrifugal force F, its vertical component Fsinwt is periodically variable perturbed force, makes axle produce the pressure of radially forced vibration; Be called exciting force, by the casing of vibrator vibration passed to cutter tooth again and carry out fragmentation.
For the utility model patent of CN 201713849U a kind of hydraulic resonant breaking hammer is disclosed like Granted publication number; It comprises vibrator and is installed on the broken tup on the vibrator; This vibrator comprises casing and two eccentric wheels that are installed in the casing; Two eccentric wheels rotate through a pair of pitch wheel in the opposite direction synchronously; And then the component of centrifugal force on the rotating shaft center line connecting direction that produces cancelled out each other, the component of rotating shaft line of centres vertical direction then mutual superposition form said exciting force.
Though the vibrator of this kind structure can prevent the occurred level skew in one direction of broken tup; But it still possibly squint by occurred level on other any direction; This will make broken position can't be accurate to a little; Promptly can't do not hope to change repeated stock under the situation at broken center fixed broken center, but also can cut down the vibrational energy on the broken direction, reduce broken effectiveness.This kind problem broken tup need be on non-other direction straight down (as straight up, horizontal direction or incline direction on) more outstanding when carrying out fragmentation; Therefore; The quartering hammer of this kind structure can only make broken tup use basically downwards, and can't obtain higher efficient in the occasion of broken hard objects.
The utility model content
The purpose of the utility model is to solve the problems of the prior art, and the quartering hammer that a kind of crushing efficiency is high, broken tup can rotate and have efficient effectiveness in vibration suppression arbitrarily is provided.
The technical scheme of the utility model is: a kind of high frequency quartering hammer; Comprise vibrator, drag link mechanism, vibration absorber and the crushing mechanism of forming by blade row and bucket tooth; Said vibrator be arranged on the said crushing mechanism and with its mechanical quiet connection; Said drag link mechanism and said crushing mechanism machinery are dynamically connected, and said vibration absorber is removable installed on the upper surface of erecting bed of said crushing mechanism.
Said crushing mechanism is broken tup, and said broken tup is that pyramidal structure or its cross section are the pointed structure of inverted triangle.
Said bucket tooth is installed in the head end of said blade row, and said blade row is provided with the strip hole that parallels with said blade row edge.
It is into a single integrated structure with it that said vibrator is welded in a side of said crushing mechanism.
Said drag link mechanism comprises upper connecting rod detent mechanism and lower link detent mechanism, and said upper connecting rod detent mechanism is articulated in the top of crushing mechanism, and the lower link detent mechanism is articulated between vibrator and the strip hole.
Said erecting bed is the part that said crushing mechanism one side is given prominence to, and is positioned on the axis of whole crushing mechanism, and said vibration absorber detachably is installed in the center of said erecting bed.
Said vibration absorber is an air spring, and said air spring detachably is connected in the erecting bed upper surface.
Said air spring comprises rubber pneumatic bag and helical spring, and helical spring places said rubber pneumatic bag inner.
Said rubber pneumatic bag is installed in said erecting bed upper surface through bolt.
The utility model can carry out fragmentation to any angle through the pull bar detent mechanism; Noise is little, breaking capacity is strong; And the axis of crushing mechanism is provided with air spring; Acceleration three power of vibration force, gravity, air spring are overlaped make bucket tooth to act on the scope of operation of bucket tooth, increased the breaking capacity of crushing mechanism greatly through the stack of above-mentioned three power, and this air spring has preferable vibration damping and energy-saving effect; The strip hole that is provided with in blade row one side has the effect of decomposing stress, thereby has increased the service life of whole crushing mechanism.
