The first driving gear 32 and the first corresponding arc-shaped outer toothed plate 33 are in meshed transmission, so that the overall angle of the movable plate 2 is adjusted, the piling component 6 is enabled to convert the angle, then the traction component 8 is started, the driving gear 32 is enabled to perform reciprocating loosening and tightening, the piling component 6 is enabled to perform up-and-down reciprocating motion, vibration of the driving gear is achieved, and automatic cleaning of residual soil is achieved.

The angle adjusting assembly 3 can rotate the first driving gear 32 under the driving of the first motor 31 according to the surrounding construction environment during the pre-piling operation in the actual operation process. The meshing transmission between the first driving gear 32 and the first arc-shaped outer toothed plate 33 realizes the angle adjustment of the movable plate 2 and the angle adjustment of the piling component 6. Thereby bringing the pile driving assembly 6 thereon to a predetermined position for driving the pile. The further enhancement equipment is applicable to more construction environments to improve the practicality effect of equipment.
