Since the drilling is from bottom to top, the iron chips generated during the drilling fall out from the lower side of the drilled material, and also includes a chip collection mechanism 7;

[0023] Chip collecting mechanism 7: It includes a synchronous pulley 71, a synchronous belt 72, a U-shaped conductive rail 73 and an electromagnet 74. The synchronous pulley 71 is rotatably connected to the left and right sides of the lower surface of the plastic partition 15 respectively. The two synchronous pulleys are connected by a synchronous belt 72. The outer surface of the synchronous belt 72 is fixedly connected to the electromagnet 74.

When the electromagnet 74 moves to the left and contacts the U-shaped conductive rail 73, the electromagnet 74 is energized to generate a magnetic force to attract the iron filings generated by drilling, and at the same time drive the iron filings to move. When the electromagnet 74 moves to the right and disengages from the U-shaped conductive rail 73, the magnetic force disappears, and the iron filings fall to the right side of the plastic partition 15. This process is repeated to collect the iron filings on the right side of the plastic partition 15, and the protective door 2 is opened to remove the iron filings.

[0024] The working principle of a pneumatic drilling device with convenient chip removal provided by the present invention is as follows: when drilling with the pneumatic drilling device with convenient chip removal, the material to be drilled is fixed inside the vertically adjacent chuck 3 and mounting block 4, the external cylinder is started, the telescopic end of the pneumatic telescopic rod 5 is extended, and the limit plate 6 is driven to move downward, so that the lower surface of the limit plate 6 is close to the upper surface of the material to be drilled, and the material is limited, the external air pump is started, and the air outlet of the external air pump is connected to the air inlet of the pneumatic motor 9, so that the output shaft of the pneumatic motor 9 rotates, drives the transmission shaft 10 to rotate, and drives the transmission cylinder 11 to rotate, drives the drill rod 12 to rotate, operates the control switch group 17, starts the electric push rod 16, and the telescopic end of the electric push rod 16 is extended, pushing the sliding cylinder 14 to move upward, drives the transmission cylinder 11 to move upward, and drives the drill rod 12 to move upward, thereby drilling the material to be drilled. Drilling is done from bottom to top, and the iron filings generated during drilling fall out from the lower side of the drilled material. At this time, the control switch group 17 is operated to start the motor 8. The output shaft of the motor 8 rotates to drive the synchronous pulley 71 to rotate (the diameters of the two synchronous pulleys 71 are different), so that the synchronous belt 72 moves, and the electromagnet 74 moves along the direction of the synchronous belt 72. The control switch group 17 is operated to energize the U-shaped guide rail 73. At the same time, the U-shaped conductive rail 73 is a horizontal U-shaped conductive rail, and the right side of the U-shaped conductive rail 73 is in a disconnected state. When the electromagnet 74 moves to the left and contacts the U-shaped conductive rail 73, the electromagnet 74 is energized to generate a magnetic force to attract the iron filings generated by drilling, and at the same time drive the iron filings to move. When the electromagnet 74 moves to the right and disengages from the U-shaped conductive rail 73, the magnetic force disappears, and the iron filings fall to the right side of the plastic partition 15. This is repeated to collect the iron filings on the right side of the plastic partition 15, and the protective door 2 is opened to remove the iron filings.
