Multifunctional all-in-one machine

The utility model relates to the technical field of pile machines, and discloses a multifunctional all-in-one machine which comprises a chassis, a main arm and a clamping box, the main arm and the clamping box are sequentially arranged on the chassis in the longitudinal direction, a power head is arranged on one side of the main arm, a winch used for driving the power head to move up and down along the main arm is arranged on the chassis, and a walking device is arranged on the lower portion of the chassis. The clamping box is slidably connected with the chassis, and the main arm is rotatably connected with the chassis. All processes of drilling and pile pressing can be completed through one device, the clamping box and the main arm can move independently, pile pressing and drilling operation can be carried out at the same time, and construction efficiency can be greatly improved. The main arm can longitudinally translate and can horizontally rotate, and the clamping box can independently and longitudinally translate, so that the drill rod can be quickly and accurately moved to the next pile position under the condition that the chassis is not moved, the operation is flexible, and the positioning is accurate.
