Each of the gears (903) is meshed with an internal gear ring frame (11). The internal gear ring frame (11) is fixedly connected to the rotating drill bit (4).

5. The automated cement mixing pile construction device according to claim 4, characterized in that: The bottom of the mixing drum (3) is fixedly connected to a first motor (401), and the output end of the first motor (401) is fixedly connected to the rotary drill bit (4).

6. The automated cement mixing pile construction device according to claim 5, characterized in that: The top of the stirring drum (3) is provided with a fixed seat (17), and a sliding frame (201) is fixedly connected to the outside of the fixed seat (17). The sliding frame (201) is slidably sleeved on the outside of the limiting post (2). A second hydraulic telescopic rod (202) is fixedly connected between the sliding frame (201) and the support base (1). A transmission rod (14) is provided at the bottom of the fixed seat (17). The transmission rod (14) is fixedly connected to the stirring drum (3). A connecting gear (15) is fixedly connected to the outside of the transmission rod (14). A second motor (16) is fixedly connected to the fixed seat (17). A transmission gear is fixedly connected to the output end of the second motor (16). The transmission gear meshes with the connecting gear (15).

7. An automated cement mixing pile construction device according to claim 6, characterized in that: The top of the support base (1) is fixedly connected to a delivery pump (13), and the output end of the delivery pump (13) is fixedly connected to a delivery pipe. The delivery pipe passes through the fixed base (17) and the transmission rod (14) in sequence and communicates with the stirring cylinder (3).

8. A method of using an automated cement mixing pile construction device, applicable to the automated cement mixing pile construction device as described in any one of claims 1-7, characterized in that: Includes the following steps: S1. When the construction positioning point is determined by measurement, the support base (1) is installed and positioned, and the construction point is targeted by the rotary drill bit (4). By starting the sliding frame (201), the second hydraulic telescopic rod (202) drives the sliding frame (201) to descend, thereby causing the fixed seat (17) to push the mixing drum (3) to descend, and the rotary drill bit (4) at the bottom of the mixing drum (3) penetrates deep into the ground. S2. The mixed concrete cement is conveyed into the mixing drum (3) through the conveying pipe by the conveying pump (13). As the cement is conveyed, the moving plate (6) inside the mixing drum (3) is pushed down, so that the cement is sprayed out through the cement outlet (5) on the outside of the mixing drum (3). S3. When the second motor (16) drives the connecting gear (15) to rotate through the transmission gear, the connecting gear (15) drives the mixing drum (3) to rotate through the transmission rod (14). The actuating component on the outside of the mixing drum (3) drives the actuating plate (9) to move, pushing the cement at the cement outlet (5) to ensure smooth cement delivery.
