[0002] The precast pipe pile core cleaning device is a mechanical device designed to remove soil and debris from precast pipe piles. Precast pipe piles are typically driven or sunk into the soil as foundations to support the loads of buildings or other structures. During the construction process, soil, gravel, and other debris may accumulate inside the piles. This debris needs to be cleaned to ensure the pile foundation's load-bearing capacity and construction quality.

[0003] Some existing devices fail to effectively collect the soil removed during the cleaning process, requiring secondary cleaning after cleaning. This not only increases construction complexity and labor intensity, but also prolongs the construction period, thereby increasing the overall cost of the project. Furthermore, the soil and impurities generated during the secondary cleaning process can pollute the construction environment and affect the sanitation and safety of surrounding areas. Therefore, a device for cleaning the core soil of prefabricated pipe piles is proposed. Utility Model Content

The rotation of rotating wheel 17 causes the engaged sliding column 19 to begin rotating, thereby driving dragon 23 to adjust its height evenly, improving the efficiency of pile core cleaning. The one-way teeth of ratchet wheel 27, through the cooperation of pawl 28, ensure that the drive system operates normally during forward rotation and does not move due to gravity when it stops rotating. During the cleaning process, motor 21 is started. The drive end of motor 21 drives spiral dragon 23 via rotating column 22. Dragon 23 transports the cleaned soil upward to the outside of the device, ensuring that the soil is collected and discharged in a timely manner.

[0038] At the same time, the cylinder 3 is activated, generating power to move forward and backward. The connecting column 4 is extended and retracted under the action of the cylinder 3, driving the movement of the fixed rod 5 and the connecting rod 6. The connecting rod 6 is connected to the fan wheel 8 through the transmission rod 7. The rotation of the fan wheel 8 transmits the movement to the two movable plates 10 with the rack 9, driving the movable plates 10 to slide left and right inside the vehicle body 1, adapting to the cleaning of pipe piles of different sizes, and effectively collecting the cleaned soil during the cleaning process. In this way, the cleaning device can efficiently and thoroughly complete the cleaning of the pile core soil, avoiding the need for secondary cleaning. Throughout the process, the various components of the device work together to ensure the cleaning efficiency and effectiveness. At the same time, the design and material selection of the vehicle body 1 also provide guarantees for the stability and durability of the device.
