Abstract
The invention provides an excavator bucket tooth. The excavator bucket tooth comprises a connecting base and a tooth top. Counter bores are formed in the left side wall and the right side wall of the connecting base. An upper concave face is arranged on the upper end face of the tooth top. A lower concave face is arranged on the lower end face of the tooth top. A first strengthening rib is arranged in the middle of the upper end face of the tooth top and comprises a strengthening rib front section, a strengthening rib middle section and a strengthening rib rear section. The strengthening rib front section is linearly upwards inclined to the portion above the front edge of the upper concave face from the front edge of the tooth top. The strengthening rib middle section is linearly upwards inclined to the portion above the middle section of the upper concave face from the joint of the strengthening rib middle section and the strengthening rib front section. The strengthening rib rear section is linearly downwards inclined to the rear edge of the upper concave face from the joint of the strengthening rib rear section and the strengthening rib middle section. The bucket tooth is sharper, has high strength so as to adapt to excavation of different depths, and is not prone to abrasion, and the service life of the bucket tooth is effectively prolonged.
