When the grounding resistance of soil is increased, because the resistance is large, current can not enter the ground through the grounding metal rod 19, the grounding effect can be influenced, because the resistance detection block 59 detects the grounding resistance, when the resistance is increased, the current in the circuit is reduced, the magnetic force of the electromagnet 86 is reduced, the repulsive force to the slide block 67 is reduced, under the action of the thrust spring 66, the slide block 67 slides to the right until being abutted to the induction block 87 and blocked, and an electric signal is sent to the driving motor 84, so that the driving motor 84 rotates in the positive direction, because the thrust spring 66 slides to the right, the connecting shaft 65 moves to the right, so that the first meshing gear 68 is meshed with the second meshing gear 71, the driving motor 84 rotates in the positive direction, the first meshing gear 68, the connecting shaft 65 and the driving pulley 64 are driven to rotate by the second belt 63, the driven pulley 62, the threaded rod 60 and the soil loosening device 61 are driven to rotate, the threaded rod 60 rotates to output the soil with small ground resistance in the storage space 20 to the soil through the soil outlet 21, the soil loosening device 61 rotates to break up the original soil, and the new soil and the old soil are mixed conveniently, so that the ground resistance is reduced, and the grounding effect of the device is improved.

When the normal work is carried out, because the circuit for detecting the grounding resistance is always connected, the power consumption is caused, the battery needs to be replaced at regular time, the driving motor 84 is started at regular time, the driving motor 84 rotates reversely, because the grounding resistance is small, the repulsion force of the electromagnet 86 to the thrust spring 66 is large, the first meshing gear 68 is not meshed with the power shaft 70, the driving motor 84 rotates reversely to drive the second cam 69 to rotate, the push rod 72, the push block 73 and the first steering block 74 are pushed to move rightwards in the rotating process, the push block 73 moves rightwards, the battery 79 slides rightwards, the first push plate 81 is pushed to slide rightwards, the first spring 80 is compressed, the first steering block 74 slides rightwards, because of the existence of the small spring 75, the push block 73 is slow to move, after the battery 79 slides rightwards for a distance, the first tangential block 74 abuts against the small spring 75 to jack the small spring 75 upwards, so that the push rod 78 pushes the battery 79 to slide upwards and exits for a certain, the battery 79 is pushed out of the battery space 25, and at this time, under the action of the second spring 83, the second push plate 82 slides forward to push another spare battery 79 to slide forward, and pushes the spare battery into the battery space 25, and power is supplied again.
