The other end of the roller 9 is rotatably connected to the vertical plate A2, and the grinding wheel A7 is located above the midline of the two rollers 9. The roller 9 is provided with a spiral pad 10 which is the same as the one for pushing the round tube. The bottoms of the vertical plate A2 and the vertical plate B8 are connected to the same bottom plate 1. The rotating drive member A is connected to the vertical plate B8 and drives the two rollers 9 to rotate in the same direction at the same time. The rotating drive member A includes but is not limited to the motor A11, and the output end of the motor A11 is connected to the roller shaft of the roller 9. The transmission assembly 12 includes gears and toothed belts, and the two gears are respectively connected to the roller shafts of the corresponding side rollers 9, and the gears on both sides are connected by toothed belt transmission, and the output end of the motor A11 is connected to the roller shaft of one of the rollers 9. The bracket 13 connects the vertical plate A2 and the vertical plate B8, and a dust cover B14 which is slidably connected to the bracket 13 is provided on the bracket 13, and a grinding wheel B16 which is rotatably connected to the inner side of the opening of the dust cover B14 is provided on the inner side of the opening of the dust cover B14, and a rotating drive member B which drives the grinding wheel B16 to rotate is provided on the dust cover B14. The rotating drive member B includes but is not limited to a motor B17, which is connected to the housing of the dust hood B14 and drives the grinding wheel B16. The lifting drive member B is connected to the bracket 13 and drives the dust hood B14. The lifting drive member B includes but is not limited to a hydraulic cylinder B15, the cylinder barrel of the hydraulic cylinder B15 is connected to the bracket 13, and the push rod of the hydraulic cylinder B15 is connected to the housing of the dust hood B14. The input end of the negative pressure dust collection component is connected to the hollow shaft and the dust hood B14, and the output end of the negative pressure dust collection component is connected to the fan 22. The negative pressure dust collection component includes a dust box 18 and a fan 22. A cavity is set in the dust box 18, and a material receiving box 23 is slidably set in the cavity. An air inlet 181 and an exhaust hole 182 connected to the interior of the dust box 18 are set on the top plate of the dust box 18, and a filter screen 183 is set in the exhaust hole 182, and the air inlet 181 and the exhaust hole 182 are both located above the inner side of the opening of the material receiving box 23. The outside of the air inlet hole 181 is connected to the air inlet pipe 19, which is connected to the hollow shaft 5 and the dust collecting cover B14. The outside of the exhaust hole 182 is connected to the exhaust pipe 21, and the other end of the exhaust pipe 21 is connected to the air inlet end of the fan 22.

[0030] In this embodiment, the motor A11 and the fan 22 are started, and the round tube is placed on the two rollers 9 along one side of the feeding trough 801. At this time, the hydraulic cylinder A4 is started, and the hydraulic cylinder A4 controls the lifting and lowering of the movable plate 3 to adjust the height of the grinding wheel A7, so that it can be inserted into the inside of the round tube. The rollers 9 rotate synchronously in the same direction to drive the round tube to rotate. Since the spiral pad 10 is set on the rollers 9, the round tube is gradually moved toward the vertical plate A2 by the propulsion of the spiral pad 10 during the rotation process. When the round tube moves below the grinding wheel B16, the hydraulic cylinder B15 is started to press the grinding wheel B16 downward so that the grinding wheel B16 contacts the round tube, and at the same time, the grinding wheel A7 just extends into the round tube. At this time, the height of the movable plate 3 is adjusted so that the grinding wheel A7 is squeezed and contacted with the inner wall of the round tube. When the round tube moves and rotates, its inner wall is in friction contact with the grinding wheel A7 to remove the burrs on its inner wall, and the outer wall is in friction contact with the grinding wheel B16 to remove the burrs on its outer surface through the high-speed rotating grinding wheel B16. When the grinding wheel rubs against the round tube, debris will be generated. At this time, the fan 22 increases the wind force, and the air and debris near the opening of the dust hood A6 and the opening of the dust hood B14 enter the dust box 18 along the air inlet pipe 19 under the action of negative pressure. The debris is blocked by the filter 803 and retained in the receiving box 23, while the air is discharged by the fan 22. After grinding, the motor A11 drives the roller 9 to rotate in the opposite direction, and the round tube is discharged along the feeding trough 801 under the guidance of the spiral pad 10. Since the height of the grinding wheel A7 and the height of the grinding wheel B16 are both adjustable, this structure is suitable for round tubes of different sizes, and the internal and external deburring work is carried out simultaneously during grinding, which is time-saving and efficient.
