[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the present invention, when the device is used, the staff first moves the mobile body to one side of the pipe pile, so that the output end of the Jiaolong conveyor is aligned with the center of the pipe pile, and then drives the working component and the Jiaolong conveyor to move downward synchronously by controlling the driving component to work. In the process of moving downward, the changing device is synchronously driven to move downward, so that the sludge and impurities in the pipe pile are crushed, and then under the action of the Jiaolong conveyor, the crushed sludge and impurities are transported to the outside of the pipe pile, thereby avoiding the need for the staff to intermittently control the pile driver to move slowly downward, simplifying the working steps, and thus improving the pile digging efficiency. At the same time, when the changing device moves to the bottom of the pipe pile, the driving component is set to work, so that the changing device moves upward when it is at the bottom of the pipe pile. At this time, the sludge and impurities in the pipe pile are The material has been broken, and the trigger component is driven to work through the connection component, so that the cleaning component can be driven by the control component to expand at the bottom of the pipe pile and stick to the inner wall of the pipe pile. In the process of moving upward, the impurities and sludge in the pipe pile and the inner wall are simultaneously removed, so that the inner wall of the pipe pile is cleaned, and the cleaning effect is further improved. After moving to the outside of the pipe pile, the cleaning component is reset through the cooperation of the connection component and the reset component, and is locked through the control component after resetting, so as to facilitate the next pile digging work and improve the convenience of work, thereby achieving the ability to crush the sludge and impurities in the pipe pile and clean the inner wall of the pipe pile at the same time, so as to avoid the effect of low pile digging efficiency and insufficient cleaning effect.

[0014] In the present invention, the staff first moves the mobile vehicle body to one side of the pipe pile, aligns the output end of the Jiaolong conveyor with the center of the pipe pile, and then controls the driving motor to work, thereby driving the reciprocating threaded rod to rotate, so that the Jiaolong conveyor moves down to dig piles. In the process of moving down, the Jiaolong conveyor drives the matching sliding sleeve and a plurality of gathered arc-shaped stamping parts to rotate synchronously through the connecting frame, and then the silt and impurities in the pipe pile are crushed with the cooperation of the cleaning blade, and then the crushed silt and impurities are transported to the outside of the pipe pile under the action of the Jiaolong conveyor, thereby avoiding the need for the staff to intermittently control the pile driver to move slowly downward, simplifying the working steps, and thus improving the efficiency of pile digging. When the L-shaped frame moves to the top of the mobile vehicle body, the L-shaped frame moves between the two connecting frames, and the mobile frame moves in the direction of the card interface under the action of the first spring telescopic rod, and drives the card rod from The side end of the telescopic baffle is embedded in the card interface. Since the L-shaped card rod is located at the side end of the passive trigger frame at this time, the second spring telescopic rod is stretched at this time, and the end of the L-shaped card rod is still embedded in the control groove. When the L-shaped frame is driven to move upward by the set reciprocating threaded rod, the trigger rod drives the arc part to move toward the spring button on the control frame under the action of the contracted third spring telescopic rod, and then drives the matching sliding sleeve to move downward through the connecting frame, driving several arc-shaped stamping parts to move away from each other with the bottom of the matching shaft as the center, and deflect through the hinge ring during the process of moving away, so that the side end of the arc-shaped stamping part fits to the inner wall of the pipe pile according to the inner diameter of the pipe pile, and makes the cleaning blade cover the gap between the two arc-shaped stamping parts, and at this time, it continues to move upward under the action of the reciprocating threaded rod, and then removes the sludge and impurities in the pipe pile, and in the process of moving, the inner wall of the pipe pile is synchronously cleaned by the arc-shaped stamping part, so as to further improve the cleaning effect.

[0015] In the present invention, when the connecting frame is out of contact with the locking rod, the connecting frame is reset through the spring damping telescopic rod after the trigger rod is reset, and in the process of resetting, it drives the first reset gear to rotate counterclockwise, thereby driving the control tooth groove rod meshing therewith to move the first sliding shaft upward in the central axis, so that the spring button is re-locked to the through-opening, and the second sliding shaft synchronously drives the matching sliding sleeve to move upward, and then, with the cooperation of the articulated telescopic rod and the articulated rod, a plurality of arc-shaped stamping parts gather together to form a cone, thereby facilitating the next pile digging work and improving the convenience during work.

During the separation process, the hinge ring 826 is deflected, and then the side end of the arc-shaped stamping part 825 is attached to the inner wall according to the inner diameter of the pipe pile, and the cleaning blade 830 covers the gap between the two arc-shaped stamping parts 825. At this time, it continues to move upward under the action of the reciprocating threaded rod 23. When it moves to the driving plate 22, the connecting frame 32 is driven to move upward synchronously through the positioning rod 41 to make the telescopic baffle 34 shrink, and through the cooperation of the first wedge block 39 and the slot 40, the two moving frames 36 are driven to approach each other, so that the positioning rod 41 is separated from the card interface 42, and in the process of approaching, the trigger rod 55 is driven by the L-shaped card rod 51 to re-compress the third spring telescopic rod 56.
