Abstract

The invention discloses an excavation tooth fixing method and system, and the method at least comprises the steps: installing a lock body in a lock body accommodation hole, and enabling the lock body to be installed on a tooth holder in a non-rotating manner; moving the bucket tooth, and inserting the nose part of the tooth holder into the inner cavity of the bucket tooth; the lock pin is inserted into a lock pin through hole in one side of the bucket tooth and is initially positioned to ensure that the concave slide way is located at the corresponding position of the elastic lock head; the lock pin penetrates into the pin hole and reaches the lock pin through hole in the other side, the elastic lock head moves to the position beside the concave lock position along the concave sliding way, the middle section of the lock pin is wrapped by the lock body, and the pin ends at the two ends of the lock pin are placed in the lock pin through holes. Rotating force is applied to the end of the lock pin to enable the lock pin to rotate by a certain angle relative to the lock body, the elastic lock head is clamped into the concave lock position from the concave slide way, the lock pin and the lock body are limited, and then the bucket tooth and the tooth holder are fixed; the invention has the advantages of simple and convenient assembly, more reliable and stable connection strength, influence on the bucket tooth strength, and capability of resisting vibration and impact in the excavation tooth operation process.

Description

technical field [0001] The invention relates to a tooth assembly of excavating equipment, in particular to an excavating tooth fixing system and a fixing method for fixing bucket teeth to a tooth seat at the front edge of a bucket. technical background [0002] Excavation equipment is commonly used in engineering and mining industries, and the bucket is an important part of the excavation equipment. When excavating equipment is performing excavation operations, the bucket plays the role of cutting and loading materials, and often collides with stones and soil. Therefore, it is necessary to install wear-resistant teeth on the front edge of the bucket. One is to protect the working end of the bucket from being worn out prematurely and too quickly; the other is to increase the sharpness of the front end of the bucket to enhance the cutting and loading capabilities of the bucket; The working end of the bucket remains sharp and efficient while reducing operating costs.
