The lifting frame 42 drives the clamping seat 43 to move downward, so that the conveying wheel 44 contacts the top of the pipe to complete the clamping and fixing of the pipe. The conveying motor 50 controls the drive rod 49 to rotate, and the drive rod 49 drives the conveying wheel 44 to rotate. The conveying wheel 44 cooperates with the support wheel 33 to realize the lateral movement of the pipe. After the pipe is transported to the designated position, the telescopic controller 8 drives the cutting machine 13 to contact the pipe. The rotary motor 10 drives the support drum 9 to rotate through the belt 11. The support drum 9 rotates synchronously through the connecting seat 12. The connecting seat 12 drives the cutting machine 13 to rotate around the pipe, thus completing the automatic cutting of the pipe. After cutting, the telescopic controller 8 drives the cutting machine 13 to retract into the connecting seat 12. The cutting machine 13 drives the air inside the control tube 16 through the control component 17 to enter the transmission chamber 15 and the transmission tube 18, so that the transmission component 19 moves inside the transmission tube 18, and the grinding blocks 20 on both sides extend out from the inside of the connecting seat 12 and abut against the pipe opening. Then, the support drum 9 rotates, and the support drum 9 drives the grinding blocks 20 to rotate through the connecting seat 12, so as to grind the pipe openings of the pipes on both sides after they are cut. During cutting, the dust pump 24 drives the air inside the dust blowing chamber 22 to be discharged from the dust blowing pipe 29, blowing off the debris attached to the cutting machine 13 and the pipe. At the same time, the dust suction pipe 28 absorbs the debris, and the filter frame 26 filters the absorbed debris. After dust removal, the air enters the inside of the dust blowing chamber 22 along the air extraction pipe 25 and the dust pump 24, realizing the rapid recovery of debris. During grinding, the dust generated during grinding can also be collected inside the dust suction chamber 23 and filtered by the filter frame 26. After grinding, the conveyor wheel 44 continues to convey the pipe, thereby completing the continuous cutting of the pipe.
