Abstract
The utility model discloses an excavator bucket tooth which comprises a tooth tip (2), a working section (7) and a connecting section (1), wherein connecting holes (6) are formed in the left side surface and the right side surface of the connecting section (1); the connecting section (1) is provided with a connecting cavity (9); the connecting cavity (9) is communicated with the connecting holes (6); the front end part (4) of the tooth tip (2) is arc; the working section (7) comprises an upper surface and a lower surface; and concave arc surfaces (3) are arranged on the upper surface and the lower surface respectively. According to the excavator bucket tooth, the front end part of the tooth tip is arc, and the concave arc surfaces are arranged on the upper surface and the lower surface of the working section respectively, so that excavation is easier, and abrasion does not happen easily, and reinforcing ribs are arranged on the connecting section, so that the service life of the bucket tooth is prolonged.
Description
Technical field
The utility model belongs to the part field on excavator, is specifically related to a kind of excavator bucket teeth.
Background technology
At present, be used for the bucket tooths mechanically such as excavator, loader and just can not divide any more tens kinds by its profile, wedge shape, flat, unicuspid knife-edge, two sharp knife shapes etc. are arranged.But all have some problems: the bucket tooth of wedge shape, flat is used more blunt and more blunt, in mining process, energy consumption is increasing on the one hand, digging efficiency is more and more lower, the excavating resistance that increases gradually for opposing on the other hand, digging force increases gradually, bucket tooth is stressed to be increased gradually, and in use the stressed support zone of bucket tooth (as bucket tooth chamber wall) can constantly be worn, the situation of bucket tooth fracture can increase like this, increasing of fracture can make equipment downtime increase, add the expense of changing the fracture bucket tooth, user's use cost is increased; Although the bucket tooth of sharp knife shape has solved the problem that bucket tooth is used more blunt and more blunt, but application life is lower, the wear weight loss of bucket tooth is than (weight that wears away in work and the ratio that the uses front weight) bucket tooth far below wedge shape and flat, the user must frequently change bucket tooth, causes and uses the cost of this bucket tooth also higher.
The utility model content
The technical problem that (one) will solve
The technical problems to be solved in the utility model is to provide a kind of excavator bucket teeth, and it not only excavates easily, and long service life.
(2) technical scheme
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of excavator bucket teeth, comprise crown (2), active section (7), linkage section (1), described linkage section (1) respectively is provided with a connecting hole (6) on the left and right side, described linkage section (1) is provided with a connection chamber (9), described connection chamber (9) and connecting hole (6) are communicated with, the leading section (4) of described crown (2) is circular arc, described active section (7) comprises upper surface and soffit, is respectively equipped with cancave cambered surface (3) on described upper surface and soffit.
As preferentially, described linkage section (1) is provided with reinforcing rib (5).
As preferably, described reinforcing rib (5) be arranged in parallel, and quantity is 2.
(3) beneficial effect
The utility model is compared to prior art, and it has following beneficial effect: because the crown leading section is circular arc, be respectively equipped with cancave cambered surface on the upper and lower surface of active section, make and excavate with simple and easy, and also not easy to wear; Owing to being provided with reinforcing rib on linkage section, increase bucket tooth application life.
Description of drawings
Fig. 1 is the structure chart of excavator bucket teeth of the present utility model.
Fig. 2 is the structure chart at another visual angle of excavator bucket teeth of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
A kind of excavator bucket teeth as depicted in figs. 1 and 2, comprise crown 2, active section 7, linkage section 1, respectively be provided with a connecting hole 6 on linkage section 1 left and right side, linkage section 1 is provided with a connection chamber 9, connection chamber 9 and connecting hole 6 are communicated with, the leading section 4 of crown 2 is circular arc, and active section 7 comprises upper surface and soffit, is respectively equipped with cancave cambered surface 3 on upper surface and soffit.Linkage section 1 is provided with reinforcing rib 5.Reinforcing rib 5 be arranged in parallel, and quantity is 2.
The utility model is because the crown leading section is circular arc, and when the native stone of bucket tooth contact, resistance can be reduced in the circular arc tip, and unlikely serious wear, be respectively equipped with cancave cambered surface on the upper and lower surface of active section, make when native stone through after crown, resistance reduces, makes to excavate with easy, and also not easy to wear; Owing to being provided with reinforcing rib on linkage section, increase bucket tooth application life.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (3)
