The loading operation process of the loader-digger can be completed by repeating the above actions.
In order for the bucket to scoop a load most quickly, it is necessary that the bucket, when lowered to the working surface, is flush with the working surface, i.e. the bucket is generally flat. Therefore, the bucket needs to be retracted to a preset position before the movable arm descends, so that the bucket can be naturally aligned with the working surface after the movable arm descends, and the next loading operation is facilitated.

Before loading operation, the preset length value of a bucket cylinder when the bucket is in a flat position is determined. When the bucket is unloaded and needs to be adjusted to a preset posture, the displacement sensing monitoring module detects that the bucket oil cylinder does not reach a preset length value, the displacement sensing detection module outputs a signal, the second bucket pilot valve 7 suction electromagnet is electrified, and the handle suction of the second bucket pilot valve 7 is kept at the position. The bucket rotates along with the rotation of the bucket cylinder, the displacement sensing and monitoring module detects that the actual length value of the bucket cylinder reaches a preset length value, at the moment, the displacement sensing and detecting module stops outputting signals, the second bucket pilot valve 7 attracts the electromagnet to be powered off, the handle of the second bucket pilot valve 7 automatically returns to the middle position, the bucket stops rotating, and the bucket reaches a preset posture; and controlling the movable arm to descend to enable the bucket to be flush with the working surface, and then carrying out the next material shoveling action.
If the bucket cylinder needs to be extended, the displacement sensing detection module outputs a signal, the suction electromagnet of the first bucket pilot valve 6 is electrified, and the handle of the first bucket pilot valve 6 is sucked and kept at the position; the bucket rotates along with the extension of the bucket cylinder; other procedures are not described in detail.
