When continuing to extract and repair the soil, just repeat the above operations. After use, each device returns to its original state.,

[0028] The hydraulic pump 461 of the present invention operates, and the hydraulic oil outlet drives the telescopic column 462 to contract. Since the fixed shaft 43 is rotatably connected to the upper sleeve of the hook groove 44, and the connecting block 463 and the connecting member 464 are rotatably connected through a rotating shaft, the hook groove 44 can quickly hook and dig the soil, greatly reducing the workload of personnel and saving the labor cost. By adjusting the telescopic length of the telescopic column 82, the trapezoidal support block 83 can achieve auxiliary support for the bottom surface. With the auxiliary counterweight stability of the counterweight block 10, the stability of the device during the soil excavation process is ensured. The motor 731 operates, and the output shaft rotates to drive the rotating shaft, the crushing hammer 732 and the stirring rod 733 to rotate. The stirring rod 733 stirs the soil evenly below, moving the larger soil clods to the upper layer. The crushing hammer 732 rotates to crush the larger bumps, and at the same time, nutrient solution is added to facilitate the comprehensive and sufficient repair of the soil.
