[0022] Specific, drive deceleration motor 206, so that the shaft connected to the chain sprocket 202 driven on the rotation, through the rest of the chain sprocket 202 so that the chain 203 rotation, in turn, through the spring rod 204 drive dredging assembly 205 movement, when the bottom of the dredging assembly 205 in the foundation pit moves, will be silt and water silted in the dredging bucket 2051 inside, when the dredging assembly 205 moves to the top, through the dredging tank can be silted in the dredging bucket 2051 inside the silt and water dump into the discharge hopper 207 inside, finally into the storage silt tank 401 middle, when the silt and water cleaning is completed, the moving trolley 1 is moved to the designated position, finally open dredging valve 402, the silt can be discharged, the operation is very simple and labor saving.

[0023] In this embodiment, the moving trolley 1 comprises a base 101, a handle 102 and four rollers 103, the rollers 103 are rotatably connected to the lower four corners of the base 101, the handle 102 is fixedly connected to one end of the base 101, the lifting mechanism 3 comprises a moving seat 301, a threaded rod 302, a support seat 303, two limiting rods 304 and a servo motor 305, one side of the moving seat 301 is fixedly connected to the middle of one of the side plates 201, the middle of the moving seat 301 is threadedly connected to the outer periphery of the threaded rod 302, the front and rear ends of the moving seat 301 are slidably connected to the outer periphery of the limiting rods 304, the lower ends of the limiting rods 304 are fixedly connected to the upper part of the support seat 303, the lower end of the threaded rod 302 is rotatably connected to the middle of the support seat 303, one side of the support seat 303 is fixedly connected to one side of the base 101, the servo motor 305 is installed on the lower part of the support seat 303, and the output end of the servo motor 305 penetrates through the support seat 303 and is fixedly connected to the lower end of the threaded rod 302.

[0024] Specifically, by pushing and pulling the handle 102, the base 101 can be moved by the rollers 103, so that the cleaning mechanism 2 can continue to move and dredge in the foundation pit. The limiting rods 304 limit the movement of the moving seat 301, so that the moving seat 301 cannot rotate relative to the support seat 303. Therefore, the servo motor 305 is driven to drive the threaded rod 302 to move the moving seat 301 up and down, thereby adjusting the height of the cleaning mechanism 2 according to the depth of the foundation pit. It is very simple, convenient and labor saving.

[0025] Working principle:

[0026] Through the push-pull handle 102, the base 101 can be moved by the roller 103, and then the cleaning mechanism 2 is moved to the upper part of the foundation pit. The movement of the base 101 is limited by the limiting rod 304, so that the movement base 301 cannot rotate relative to the support base 303. Therefore, the servo motor 305 is driven, so that the threaded rod 302 can drive the movement base 301 to move up and down, thereby adjusting the height of the cleaning mechanism 2 according to the depth of the foundation pit. Then the cleaning mechanism 2 is moved by the moving trolley 1, and the reduction motor 206 is driven to rotate the shaft connected to the sprocket 202, and the remaining sprocket 202 is rotated to rotate the chain 203, and then the spring rod 204 drives the dredging assembly 205 to move. When the bottom dredging assembly 205 moves in the foundation pit, the silt and accumulated water will be scooped into the dredging bucket 2051. When the dredging assembly 205 moves to the top, the silt and accumulated water in the dredging bucket 2051 can be poured into the discharge hopper 207 through the silt discharge groove, and finally discharged into the silt storage box 401. When the silt and accumulated water are cleaned, the moving trolley 1 is moved to the specified position, and finally the silt discharge valve 402 is opened to discharge the silt.
