The specific embodiment
As shown in Figures 1 to 3, high frequency quartering hammer of the present invention comprises vibrator 1, broken blade row 2, bucket tooth 3, at least one cover pull bar detent mechanism 5 and housing 7 is installed; This fragmentation blade row 2 is fixed on the shell as shown in Figure 5 104 of vibrator 1, and broken blade row 2 is positioned on the perpendicular, and this bucket tooth 3 is installed on the end of broken blade row; This vibrator 1 links to each other with installation housing 7 by vibration absorber 4; Each overlaps the pull bar detent mechanism and is installed on and installs between housing and the broken blade row, bucket tooth is not changed at described high frequency quartering hammer under the situation of position hit on same point.
Shown in Fig. 1 to 4, this pull bar detent mechanism 5 can comprise connecting axle 51, left lever 52 and right pull bar 53, the two ends of this connecting axle 51 are fixed on respectively on the sidewall respect to one another that housing 7 is installed, and this connecting axle 51 is perpendicular to the perpendicular at broken blade row 2 places, this left lever 52 and right pull bar 53 are divided into the left side and the right side of broken blade row 2, one end of this left lever 52 is installed on the connecting axle 51 rotatably to limit its axially movable mode, the left surface of the other end and broken blade row 2 is hinged, in like manner, one end of this right side pull bar 53 is installed on the connecting axle 51 rotatably to limit its axially movable mode, and the right flank of the other end and broken blade row 2 is hinged.Like this, if adopt at least two cover pull bar detent mechanisms 5, then can guarantee the high frequency quartering hammer not the situation bucket tooth 3 of change location act on the same point all the time, and horizontal-shift on any direction can not take place, and, even adopt a cover pull bar detent mechanism 5,, fully also can obtain above-mentioned precision if make the active area of left and right pull bar and broken blade row 2 enough big.In the present embodiment, adopt two cover pull bar detent mechanisms 5, as upper connecting rod detent mechanism 5a and lower link detent mechanism 5b, the two is divided into the above and below of vibrator 1 respectively.When adopting three cover pull bar detent mechanisms 5, the pin joint of left and right pull bar and broken blade row 2 is triangularly arranged, such location structure is more firm.
In addition, according to design principle of the present invention as can be known, the pull bar detent mechanism can only comprise a pull bar fully, this pull bar is at one end hinged with installation housing 7, side at the other end and broken blade row 2 is hinged, because pull bar can apply pulling force or thrust to broken blade row 2, therefore, hit the effect on same point under the situation that the pull bar detent mechanism of this kind structure also can obtain to make bucket tooth not change the position at described high frequency quartering hammer fully, if adopt the pull bar detent mechanism of many this kind of cover structures, it can be divided into the not homonymy of broken blade row 2.
The vibrator 1 that this kind pull bar detent mechanism 5 is used eccentric wheel structure can obtain more accurate broken direction.As shown in Figure 5, this kind vibrator 1 comprises shell 104, first driving shaft 101, the second driving shaft (not shown), first eccentric wheel 102 and the second eccentric wheel (not shown), the central axis of first and second driving shafts is positioned on the same horizontal plane, and it is vertical with the central axis of connecting axle 51, this first and second eccentric wheel respectively with limit its in relative rotation mode be installed on first and second driving shafts, first and second driving shafts are by only showing the gear that is installed on first driving shaft among the pair of engaged gears 103(figure) rotate synchronously in the opposite direction, hydraulic motor 6 drives first driving shaft 101 and rotates.Like this, though the pulling force perpendicular to broken blade row 2 of centrifugal force that first, second eccentric wheel can be offset and left and right pull bar all is positioned on the horizontal direction, (the former is fore-and-aft direction but be perpendicular to one another, the latter is a left and right directions), this can make the active force of 2 of pull bar detent mechanism 5 and broken blade rows reduce, improve the utilization rate of vibrational energy, prolong its application life.
In addition, in the present embodiment, this vibration absorber 4 adopts rubber air spring, and this kind damping device can reach the effectiveness in vibration suppression more than 90%, reduces the destructive power of vibratory impulse power to excavator and installation shell effectively.
The top of the installation housing 7 of this high frequency quartering hammer is equipped with and connects support 8, during application, the high frequency quartering hammer is connected on the excavator by connecting support 8, and the advancing of excavator, oil return fluid pressure line are communicated with the respective line of hydraulic motor.After the unlatching excavator provides hydraulic power supply, hydraulic motor will drive the rotation of first and second eccentric wheels, produce powerful vibration force with the axle center rotation, by the vibration of vibrator 1, make 3 pairs of objects of bucket tooth or rock carry out fragmentation.High frequency quartering hammer of the present invention is to carry out the fragmentation acting with the impact force of per minute 2000-3000 time, and can not make bucket tooth produce any horizontal-shift.
Only being preferred embodiment of the present invention in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should belong to technology category of the present invention.
