Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0035] Such as Figures 1 to 12 The excavator bucket tooth assembly of the present invention with an improved connection structure is shown, which includes a bucket tooth 100, a tooth seat 200 and a lock pin 300, and the bucket tooth 100 and the tooth seat 200 pass through the lock pin 300 Fixed connection.

[0036] The shape of the bucket teeth 100 is similar to that of commonly used excavator teeth, both of which are flat, with wide upper and lower sides and narrow left and right sides. The bucket tooth 100 includes a tip portion 1 and a connecting portion 2 , and the size gradually increases from the tip portion 1 to the connecting portion 2 . The connecting part 2 is provided with a socket 20, the socket 20 is narrow inside and wide outside, the upper and lower sides of th...

Abstract

The invention discloses an excavator dipper tooth assembly with the improved connecting structure. The excavator dipper tooth assembly comprises a dipper tooth, a tooth base and a lock pin piece. The dipper tooth is fixedly connected with the tooth base through the lock pin piece, and the lock pin piece comprises a transverse pin, a vertical pin and a clamping spring. A protruding part of the tooth base is inserted into an inserting opening of the dipper tooth, the transverse pin is inserted into a transverse pin hole, the vertical pin is inserted into a vertical pin hole and a through hole, and the clamping spring is clamped in an annular groove in the vertical pin. According to the excavator dipper tooth assembly with the improved connecting structure, the dipper tooth is connected with the tooth base through the transverse pin and the vertical pin, the bonding strength and the bonding compactness between the dipper tooth and the tooth base are enhanced, the falling-off possibility of the dipper tooth is reduced, and trouble and labor are saved during working of an excavator device accordingly.

Description

technical field [0001] The invention belongs to the technical field of spare parts of excavating and loading operation machinery in engineering machinery and mining machinery, and in particular relates to an excavator bucket tooth assembly with an improved connection structure. Background technique [0002] An excavator is a commonly used construction machine. The excavator mainly uses a bucket to excavate materials that are higher or lower than the bearing surface. The main function of the bucket teeth on the bucket is to break the material, so when digging, the impact force on the bucket teeth is very large. When the material encountered is relatively hard, or when the operation is improper, the bucket teeth are very easy to be damaged and broken. The more common bucket tooth components on the market at present include bucket teeth, tooth holders and pins. The tooth holders are welded to the bucket, and the bucket teeth are fixedly connected to the tooth holders through p...
