When it is necessary to drill deeper soft soil, the fixing bolt 644 is removed, the cylinder 54 is started to drag the mounting plate 53 to move upward, so that the clamping block 642 is separated from the mounting tube 643, and then the mounting tube 643 is removed from the first threaded block 646, and a group of threaded tubes 647 and a group of connecting blocks 645 are installed on the top of the first threaded block 646, and then the mounting tube 643 is installed on the outside of the first threaded block 646, and the mounting tube 643 and the clamping block 642 are fixed by the fixing bolts 644, and the second motor 61 is started again for drilling, and the above process can be repeated to fix the threaded tube 647 and a group of connecting blocks The connecting block 645 is assembled to increase the drilling depth, avoid the problem of insufficient length of the drill bit 649 in the deep soft soil, and improve the drilling effect. After the drilling is completed, the second motor 61 can be disassembled through the mounting sleeve 62 and the mounting bolt 63, and the mounting tube 643 will be separated from the mounting block 641. When the disassembly is completed, one end of the winding rope 44 is fixed to the outside of the fixing ring 653, and then the connecting plate 650 is installed on the top of the mounting tube 643 through the plug-in block 651, and then it is fastened by the fixing bolt 644, and the first motor 41 is started to drive the winding roller 43 to rotate, and the winding rope 44 is wound. The winding rope 44 will take out the drill bit 649 deep in the soft soil, which is fast and convenient, and improves the drilling efficiency. The winding rope 44 passes through the outside of the guide wheel 453, drives the guide wheel 453 and the rotating rod 452 to rotate, so as to achieve the effect of protecting the winding rope 44 and reduce the wear of the winding rope 44.
