A main bucket ear connected to the output shaft of the bucket driving mechanism and an auxiliary bucket ear connected to the other end of the hydraulic telescopic rod are welded on the outer wall of the bucket.

[0007] A fixed connection buckle assembly for fixing the bucket is arranged on the main bucket ear and the auxiliary bucket ear. The fixed connection buckle assembly comprises a pin rod passing through the main bucket ear and the auxiliary bucket ear, a concave block clamped on the pin rod, an arc-shaped sliding block passing through the opening side of the concave block, and a plurality of electric sliding rods for driving the arc-shaped sliding block to move. The arc surface end of the arc-shaped sliding block corresponds to the outer wall end of the pin rod.

[0008] As an improvement, the arc-shaped sliding block overhanging hole of the concave block side wall is welded with a sealing wall plate, and the output end of the electric sliding rod passes through the sealing wall plate.

[0009] As an improvement, the output shaft of the electric sliding rod is connected with the bottom surface of the arc-shaped sliding block and the outer wall of the sealing wall plate and the base of the electric sliding rod through a bolt structure.

[0010] As an improvement, the output shaft of the excavator driving mechanism is connected with the top surface of the concave block above the main bucket ear through a bolt structure, and the output shaft top surface of the hydraulic telescopic rod is connected with the concave block above the auxiliary bucket ear through a pin structure.

[0011] As an improvement, the pin rod is a T-shaped rod, and the output end side of the pin rod is provided with a fastening screw passing through the pin rod.

[0012] As an improvement, the bottom surface opening of the concave block is a tapered opening.

[0013] Compared with the prior art, the device replaces the pin with a pin rod of the same size, installs a concave block above the pin rod, fixes the connection of the excavator driving mechanism and the main bucket ear through the clamping of the concave block and the pin rod, and closes the opening of the concave block through the arc-shaped sliding block on one side of the opening end of the concave block (the arc-shaped sliding block is driven by a plurality of electric sliding rods fixed on the outer wall end of the concave block), so that the pin rod is clamped in the concave block, thereby completing the connection of the excavator bucket. Similarly, when disassembling, only the arc-shaped sliding block needs to be retracted, and the excavator bucket can be automatically disassembled. BRIEF DESCRIPTION OF DRAWINGS
