Abstract
The invention discloses a novel bucket tooth which comprises a tooth seat and a bucket tooth body. The surface of the tooth seat is fixedly connected with an installation head portion. A fixing hole is formed in the surface of the installation head portion. An installation groove is formed in the side face of the bucket tooth body. The installation head portion is connected in the installation groove in an inserted manner. An installation hole is formed in the bottom of the inner wall of the installation groove. The installation hole is in a regular hexagon shape. A lock nut is connected in the installation hole in a clamping manner. A through hole is formed in the upper surface of the bucket tooth body, and the through hole communicates with the installation groove. According to the novel bucket tooth, due to the fact that a fixing pin is improved to be installed in the vertical direction, the operation space is large during installation, the phenomenon that space is narrow when bucket teeth get close to each other, and consequently installation operation is not convenient is avoided; and in addition, due to the fact that the surface of the installation head portion and the inner wall of the installation groove are improved to be of an eight-face structure, the inner angle is increased, the stress effect exerted on the bucket tooth during work is reduced, and the risk that the bucket tooth is fractured is greatly avoided.

Preferably, the section of the securement head is also octagon, and the securement head is mutually matched with mounting groove.
Preferably, the length of the bucket tooth is 6-8 centimetre, and the through hole is opened at 3/4 distance of bucket tooth upper surface.
(3) beneficial effect
The invention provides a kind of new bucket tooth.Possesses following beneficial effect：
The present invention is by arranging securement head, fixing hole, bucket tooth, mounting groove, installing hole, locking nut, through hole and fixation
Pin, is installed so that when installation by the way that steady pin is improved in the vertical direction, and working place is big, will not be because of bucket
Tooth is close to each other to cause narrow space so that installation operation is inconvenient, and by by the surface of securement head and mounting groove
Inwall is improved to octahedral structure, so that interior angle increase, reduces the stress that bucket tooth is operationally subject to, greatly keeps away
The risk of bucket tooth fracture is exempted from.
Description of the drawings
Fig. 1 is explosive view of the present invention.
In figure：1 toothholder, 2 securement heads, 3 fixing holes, 4 bucket tooths, 5 mounting grooves, 6 installing holes, 7 locking nuts, 8 through holes, 9
Steady pin, 10 protective blocks.
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 is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.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 creative work is not made
Embodiment, belongs to the scope of protection of the invention.
As shown in figure 1, the present invention provides a kind of technical scheme：A kind of new bucket tooth, including toothholder 1 and bucket tooth 4, bucket tooth 4
Lower surface be smooth plane, the upper surface of bucket tooth 4 is smooth streamlined so that what bucket tooth 4 was operationally subject to rubs
Power is less, so as to reduce the abrasion of bucket tooth 4, improves the service life of bucket tooth 4, and the surface of toothholder 1 is fixedly connected with mounting head
Portion 2, the surface of securement head 2 offers fixing hole 3, and the side of bucket tooth 4 offers mounting groove 5, and the intracavity section of mounting groove 5 is
Octagon, and octagonal eight interior angles are equal, the section of securement head 2 is also octagon, securement head 2 and the phase of mounting groove 5
Mutually matching, securement head 2 is plugged in mounting groove 5, and the bottom of the inwall of mounting groove 5 offers installing hole 6, and installing hole 6 is positive six
