The transverse regulating screw is threadedly connected to the part of the rear moving frame 2 that is stuck in the interior of the processing table 1. A longitudinal adjusting motor 5 is installed on the top of the rear moving frame 2, and a longitudinal regulating screw is installed on the output end of the longitudinal adjusting motor 5. The longitudinal regulating screw is threadedly connected to the mounting top seat 3. A rotating motor 6 is installed on the top of the mounting top seat 3 and at the front side. A transmission shaft 7 is installed on the output end of the rotating motor 6. A drill mounting seat 10 is provided at the bottom end of the transmission shaft 7. The bottom end of the transmission shaft 7 passes through the mounting top seat 3 and extends to the bottom of the mounting top seat 3. A debris cleaning device 8 is provided at the bottom of the mounting top seat 3.

[0022] The debris cleaning device 8 includes a dust box 81, an upper tube 82, a dust extraction joint 83, an outer dust extraction opening 84, a filter cylinder 85, a lower pressure blade 86, an upper connecting plate 87, a cleaning paddle 88, an air blowing opening 89, an inner dust extraction opening 90, an inner blocking frame 91, a bottom blocking ring 92, a bottom guide ring 93, an outer protective curtain 94, an outer telescopic partition cover 95 and a bottom support rod 96. The dust box 81 is installed at the bottom of the mounting base 3, and the transmission shaft 7 is connected to the dust collector. The position where the dust box 81 contacts is connected by a bearing. The upper tube body 82 is installed on the top of the dust box 81. The dust extraction joint 83 is installed on the top of the upper tube body 82. The top of the dust box 81 is provided with an opening communicating with the interior of the upper tube body 82. The bottom of the dust box 81 is provided with an external dust extraction opening 84 at a position close to the outside. The filter screen cylinder 85 is installed on the inner wall of the bottom of the dust box 81. The lower pressure blade 86 is on the outer wall of the transmission shaft 7 and is located at the filter screen cylinder 8 5, the upper connecting plate 87 is installed on the outer wall of the transmission shaft 7 and is located above the filter cylinder 85, the cleaning paddle 88 is installed at the bottom of the upper connecting plate 87 and is located outside the filter cylinder 85, the blowing opening 89 is opened at the bottom of the dust box 81 and is located at the position of the filter cylinder 85, the inner dust extraction opening 90 is opened at the bottom of the dust box 81 and is located outside the filter cylinder 85, the inner blocking frame 91 is installed at the bottom of the dust box 81 and is located outside the inner dust extraction opening 90, the bottom blocking ring 92 is installed on the outer side of the lower end of the inner blocking frame 91, the bottom guide ring 93 is installed at the bottom end of the inner blocking frame 91, the outer protective curtain 94 is installed at the bottom of the dust box 81 and is located outside the inner blocking frame 91, the outer telescopic partition cover 95 is installed at the bottom of the dust box 81 and is located outside the outer dust extraction opening 84, and the bottom support rod 96 is installed at the bottom of the outer telescopic partition cover 95.

[0023] Furthermore, the lower pressure blade 86 and the cleaning paddle 88 are both spiral-shaped, and the spiral directions of the lower pressure blade 86 and the cleaning paddle 88 are opposite. The lower pressure blade 86 rotates to discharge the gas inside the filter screen cylinder 85 downward, and the gas is blown downward through the blowing opening 89 to the position where the tool is cutting, so that the debris flies up, thereby facilitating the extraction and cleaning of the debris with the air flow, thereby improving the cleaning effect. At the same time, when the gas outside the filter screen cylinder 85 enters the inside of the filter screen cylinder 85, the debris will be adsorbed on the surface of the filter screen cylinder 85, and the transmission shaft 7 drives the cleaning paddle 88 to rotate through the upper connecting plate 87. The rotation of the cleaning paddle 88 will move the debris adsorbed on the outside of the filter screen cylinder 85 upward for cleaning, thereby preventing the filter screen cylinder 85 from being blocked.

[0024] Furthermore, the blowing hole 89 is opened at an angle, and the bottom end of the blowing hole 89 is bent in a clockwise direction, so that when the gas blows downward along the blowing hole 89, a vortex is formed on the outside of the cutter head, thereby improving the blowing and cleaning effect of debris.

A sealed switch plate is installed inside the mounting cavity. The suction pressure is adjusted by the amount of debris during revolution. During high-pressure suction, the sealed switch plate installed in the mounting cavity is controlled to open and release the seal on the external dust extraction opening 84. The five external dust extraction openings 84 cooperate with the internal dust extraction opening 90 in the middle to perform suction, and the suction force is increased to prevent the debris from being uncleaned.

[0026] Furthermore, the bottom end of the bottom support rod 96 is inlaid with a ball to reduce friction during the moving and cutting process.

[0027] Furthermore, a ball bushing is installed on the outer surface of the mounting base 3, and each ball bushing is equipped with four sliding pads to protect the bushing from debris and dust and increase the smoothness during operation.

[0028] When in use, connect the negative pressure dust extraction pipe to the top of the dust extraction joint 83, fix the wooden board to be processed above the processing table 1, install the tool under the drill bit mounting seat 10, and drive the transmission shaft 7 to rotate by rotating the motor 6. The transmission shaft 7 drives the drill bit mounting seat 10 and the tool to rotate to process the wooden board. At the same time, exhaust is carried out through the negative pressure dust extraction pipe, so that the inside of the dust collection box 81 and the upper tube body 82 becomes a negative pressure state, and the external air flows inward through the gap under the outer telescopic partition cover 95. After the air flows into the inside of the outer protective curtain 94, it flows upward and drives the wood chips to flow upward, so that the debris flows upward along the inner dust extraction opening 90 to the inside of the dust collection box 81, and then upward along the inside of the dust collection box 81 into the inner part of the upper tube body 82 The dust is finally extracted through the dust extraction joint 83, and at the same time, the transmission shaft 7 drives the lower pressure blade 86 to rotate, and the rotation of the lower pressure blade 86 discharges the gas inside the filter cylinder 85 downward, and the gas is blown downward through the blowing opening 89 to the cutting position of the tool, so that the debris flies up, thereby facilitating the extraction and cleaning of the debris with the air flow, thereby improving the cleaning effect. At the same time, when the gas outside the filter cylinder 85 enters the inside of the filter cylinder 85, the debris will be adsorbed on the surface of the filter cylinder 85, and the transmission shaft 7 drives the cleaning paddle 88 to rotate through the upper connecting plate 87. The cleaning paddle 88 rotates to push the debris adsorbed on the outside of the filter cylinder 85 upward for cleaning, preventing the filter cylinder 85 from being blocked, and the upward-moving debris flows upward with the air flow and is extracted.
