[0021] Furthermore, a method for using an excavator bucket welding device for earthwork construction machinery comprises the following steps:

[0022] S1: After the excavator bucket is fixed by the clamping component, the mechanical arm is started to push the welder to weld the excavator bucket. When the position of the mechanical arm needs to be adjusted, the electric push rod is started to push the sliding frame to slide inside the sliding hole. When the sliding frame moves, it pushes the mechanical arm to move synchronously. When the mechanical arm moves, the position of the welder can be adjusted;

[0023] S2: Start the power device to drive the gear to rotate. The gear drives the rotating ring to rotate on the surface of the fixed ring through the meshing with the groove ring. When the rotating ring rotates, it drives the mechanical arm to rotate through the connection between the circular groove frame and the hydraulic rod, so that the mechanical arm can drive the welder to rotate in a circle, so as to adjust the position of the welder;

[0024] S3: After placing the excavating bucket inside the bearing component, start the electric telescopic rod to move downward. When the electric telescopic rod moves downward, it pulls the linkage plate to move through the lifting plate. When the linkage plate moves, it pushes the pressure rod to move through the connection between the rectangular frame and the extension plate. The pressure rod pushes the moving frame to move toward the center of the cross slot frame and squeezes and fixes the excavating bucket through the clamping block.

[0025] S4: After placing the excavation bucket on the top of the load-bearing plate, the load-bearing plate is used to support and limit the excavation bucket. When the pressure rods move closer to each other, the pressure rods push the load-bearing plate downward through the connection between the bent plate and the inclined plate. The height of the excavation bucket is lowered through the load-bearing plate, so that the clamping block can clamp and fix the excavation bucket more stably.

[0026] The present invention has the following beneficial effects:

[0027] After the excavating bucket is placed inside the bearing component, the bearing component is used to fix the excavating bucket, and the clamping component is used to squeeze and fix the excavating bucket in the bearing component, thereby improving the stability of the excavating bucket during welding. After the excavating bucket is fixed, the welding component is started to weld the excavating bucket, thereby improving the convenience of welding the excavating bucket.

[0028] After the present invention completes fixing the excavation bucket by the clamping component, the mechanical arm is started to push the welder to weld the excavation bucket. When the position of the mechanical arm needs to be adjusted, the electric push rod is started to push the sliding frame to slide inside the sliding hole. The sliding frame pushes the mechanical arm to move synchronously when moving. The mechanical arm can adjust the position of the welder when moving, thereby improving the convenience of the welder welding the excavation bucket. At this time, the power device is started to drive the gear to rotate, and the gear drives the rotating ring to rotate on the surface of the fixed ring through the engagement with the groove ring. When the rotating ring rotates, the mechanical arm is pushed to rotate through the connection between the circular groove frame and the hydraulic rod, so that the mechanical arm can push the welder to rotate in a circle, so as to adjust the position of the welder, and the hydraulic rod can adjust the height of the mechanical arm, and the motor is started to drive the shaft rod to rotate inside the circular hole frame. When the shaft rod rotates, it will push the fixed ring to rotate. The mechanical arm can adjust the welder by flipping, thereby further improving the convenience of adjusting the welder.

[0029] After the excavating bucket is placed inside the bearing component, the electric telescopic rod is started to move downward. When the electric telescopic rod moves downward, the linkage plate is pulled to move by the lifting plate. When the linkage plate moves, it pushes the pressure rod to move through the connection between the rectangular frame and the extension plate. The pressure rod pushes the moving frame to move toward the center of the cross-slot frame and squeezes and fixes the excavating bucket through the clamping block, thereby improving the convenience of fixing the excavating bucket and avoiding shaking of the excavating bucket during welding.

[0030] After the excavating bucket is placed on the top of the bearing plate, the bearing plate is used to support and limit the excavating bucket. When the pressure rods move closer to each other, the pressure rods will push the bearing plate to move downward through the connection between the bent plate and the inclined plate. The height of the excavating bucket is lowered by the bearing plate, so that the clamping block can clamp and fix the excavating bucket more stably. When the pressure rods move away from each other, the inclined plate can push the bearing plate to move upward, so as to unload the welded excavating bucket.

[0031] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
