Preferably, the afterbody of described vibrations tooth root is for connecting the mounting head of quartering hammer.
Preferably, described helicla flute is internal conical surface, and its bottom is semi circular surface.
Preferably, at the front end of described vibrations tooth root, be provided with a pair of dop, described bucket tooth afterbody and dop relative position at least one side offer breach, described alignment pin is arranged between described dop and breach.
Preferably, described a pair of dop is oppositely arranged on the front end of vibrations tooth root, and one-body molded with the head of vibrations tooth root.
Preferably, described alignment pin is elastic positioning pin.
Preferably, described bucket tooth head comprises crown and the bucket tooth middle part that is connected bucket tooth afterbody and crown, and described bucket tooth middle part consists of four cambered surfaces.
Preferably, the cross section of described crown is triangle.
Vibrations tooth root of the present utility model is inner cased type, dismounting assembling is simple, saved the replacing time, the utility model locks vibrations bucket tooth with spiral top semicircle preparation alignment pin, in the powerful impulsive force of vibrator, through shaking the round face of internal conical surface, helicla flute and bottom semicircular of tooth root, pass to vibrations bucket tooth, with elastic positioning pin, vibrations tooth root and vibrations bucket tooth are closely united, become as a whole, then by shaking the crown on the outer inclined-plane of bucket tooth, rock object is carried out to fragmentation.Helicla flute bottom semicircular face of the present utility model, to reduce impulsive force, increases lifting surface area, has improved service life, and the vibrations bucket tooth of the utility model preparation high abrasion declines to solve the intensity causing because of excess Temperature, the problem that abrasion resistance declines and brings.

The specific embodiment
For technological means, technical characterictic, utility model object and the technique effect that the utility model is realized is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As Fig. 1,1a, 1b, 1c and 1d are depicted as a kind of high-frequency breaking hammer vibrations blade row of the present utility model, comprise vibrations tooth root 100 and vibrations bucket tooth 200, vibrations bucket tooth 200 is plugged to the inside of described vibrations tooth root 100; Specifically will shake in the following way tooth root 100 and 200 grafting of vibrations bucket tooth, head 101 at vibrations tooth root 100 interiorly offers helicla flute 102 along its horizontal axis, the bucket tooth afterbody 201 of vibrations bucket tooth 200 coincide for helical form with helicla flute 102 profiles, bucket tooth afterbody 201 is inserted in this helicla flute 102 and its clamping, because geomery matches, so both closely cooperate together.In order to guarantee its matching relationship closely, in bucket tooth afterbody 201 and helicla flute 102 joints, be provided with alignment pin 300 and be locked.
If Fig. 2,2a, 2b, 2c and 2d are vibrations tooth root 100 of the present utility model, its afterbody, for connecting the mounting head 103 of quartering hammer, can be connected with vibrator by this mounting head 103.Head 101 at vibrations tooth root 100 interiorly offers helicla flute 102 along its horizontal axis, and helicla flute 103 be internal conical surface, is semi circular surface bottom it.Front end at vibrations tooth root 100 is provided with a pair of dop 104, and dop 104 is oppositely arranged on the front end of vibrations tooth root 100, and one-body molded with the head 101 of vibrations tooth root 100.The position relative with dop 104 at bucket tooth afterbody 201 at least simultaneously offers breach 202, and alignment pin 300 is arranged between dop 104 and breach 202, and the alignment pin 300 in the utility model is elastic positioning pin.
