In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
Have technology description in required use accompanying drawing be briefly described it should be apparent that, drawings in the following description be only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, acceptable
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the structural representation of an embodiment of crushing teeth of the present invention；
Fig. 2 is the structural representation of the connect base matching with Fig. 1 embodiment；
Fig. 3 is the installation diagram of crushing teeth and connect base；
Fig. 4 is the schematic diagram installed on shaker arm of application example of Fig. 3.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
Shown in Figure 1, one embodiment of the invention, a kind of crushing teeth, it is arranged on the shaker arm 9 of quartering hammer, it is special
Levy and be：Described crushing teeth includes a center carcass 1, and described center carcass 1 is in tetrapyamid shape, and its conehead end face is square；Institute
State and in the middle part of the symmetrical two sides of center carcass 1, be equipped with the integrally formed shaft of rib 2 with described center carcass 1；The two of described shaft of rib 2
Side seamed edge adjacent with described center carcass 1 respectively constitutes a guide groove 3；On the zone of action between described crushing teeth and ground
Soil dust outwards can derive along described guide groove 3.In an embodiment, the material of this crushing teeth adopts high alloy steel casting,
So, the present invention passes through to set up shaft of rib 2 on center carcass 1, on the one hand, because center carcass 1 is formed in one with shaft of rib 2,
Shaft of rib 2 can play booster action to center carcass 1, is effectively improved the bulk strength of crushing teeth and rigidity so as to not easy to break
Disconnected；On the other hand, the guide groove 3 by being constituted between center carcass 1 and shaft of rib 2, in the state of high frequency vibration broken rock and soil,
Be conducive to the soil dust on the zone of action between crushing teeth and ground to derive, reduce crushing teeth soil-entering resistance, prevent soil dust simultaneously
Adhesion crushing teeth affects the sharp, thus effectively improving crushing teeth power performance and its crushing efficiency of crushing teeth；Additionally, passing through
The center carcass 1 of tetrapyamid shape and the shaft of rib 2 of square strip design, make crushing teeth form 8 sharp keen corner angle sides, broken
During detritus soil, the effect of tear ground can be played in corner angle side, thus reaching preferable crushing effect.
More preferably, described crushing teeth is fixedly connected with described shaker arm 9 end by connect base 4.Described connect base 4
Including web 41, it is connected to described web 41 both sides and the wing plate 42 for being fixedly connected with described shaker arm 9 end, implementing
In example, pass through between described wing plate 42 and shaker arm 9 end to be welded and fixed.It is provided with the middle part of described web 41 along described wing plate 42 phase
The raised boss 43 of opposite direction；Correspondingly, the top of described crushing teeth is provided with the set hole 5 being connected with described boss 43；?
In embodiment, this boss 43 is preferably tetragonous cone table, and accordingly, set hole 5 is preferably rectangular pyramid set endoporus, using the set of crushing teeth
The boss 43 of hole 5 and connect base 4 is fabricated to the tight fit of four sides taper, limits the circumferentially displaced of crushing teeth and radial direction
Displacement.Described web 41 is provided with multiple through holes 44 being available for bolt connection；Correspondingly, the top of described crushing teeth be provided with multiple
It is available for the mounting seat 6 that nut 7 is fixing and is connected with bolt 8；In an embodiment, bolt 8 and nut 7 are provided with 6 groups, during installation altogether,
Nut 7 is fixed in mounting seat 6, bolt 8 be may pass through through hole 44 and connected with corresponding nut 7, thus carrying out axle to crushing teeth
To fastening, limit the axial displacement of crushing teeth, so that the axial gap between boss 43 and set hole 5 is further taken out simultaneously and be close to
Close, be conducive to the power of shaker arm 9 to transmit, strengthen the crushing force of crushing teeth.It can be seen that, crushing teeth can effectively with shaker arm 9 even
It is integrated, the comprehensive fixation of crushing teeth is difficult to get loose, the common stress of multiple bolt 8 is unlikely to deform, and needs more after broken odontotripsis
When changing, unclamp bolt 8, its easy accessibility.
More preferably, the end of described shaft of rib 2 is connected with the conehead end face sideline transition of described center carcass 1 by circular arc,
Conehead insertion ground vibration is conducive to crush.
Above disclosed be only a kind of preferred embodiment of the present invention, certainly the power of the present invention can not be limited with this
Sharp scope, the equivalent variations therefore made according to the claims in the present invention, still belong to the scope that the present invention is covered.
