A sub-gear 21 is coaxially fixed at one end of the roller brush 11, and the sub-gears 21 mesh with each other. A turbine 18 is arranged between each baffle 9 and the drum 13. The turbine 18 is connected in series between the water inlet pipe 19 and the water supply module. A main gear 20 is coaxially fixed on the turbine shaft of the turbine 18, and the main gear 20 meshes with the adjacent sub-gear 21. The function of the turbine 18 is to convert the kinetic energy of the water flow into the rotational power of the turbine shaft through the turbine, so that the turbine shaft can drive the roller brush 11 to rotate through the main gear 20 and the sub-gear 21.

[0020] The water outlet 27 is in the shape of a long strip as a whole, and the water outlet 27 is arranged corresponding to the adjacent roller brush 11, so that the direction of the water flow sprayed from the water outlet 16 can be tangent to the outer contour of the roller brush 11. In order to make the sprayed water flow efficiently flush away the debris remaining on the outer surface of the roller brush 11, the direction of the water flow sprayed from the water outlet 16 can be tangent to the outer contour of the roller brush 11, so that the debris flushed away at the outermost point of the outer contour of the cleaning wheel can directly fall onto the guide plate 25 below. The guide plate 25 has a chamfered surface at the lower part of one end close to the roller brush 11, and the end of the guide plate 25 is in contact with the surface of the roller brush 11 adjacent to the upper side thereof. Figure 11-12 As shown, by providing an oblique surface, the guide plate 25 can extend between two adjacent roller brushes 11, so as to shield the lower roller brush 11 from the sewage coming down from above as much as possible, and this end of the guide plate 25 contacts the adjacent roller brush 11, and can act as a cleaning shovel, scooping up the debris and waste water remaining on the surface of the roller brush 11 when it rotates.
[0021] The overall workflow of the present invention is as follows: Before use, Fig.13 As shown, the circular saw 28 is installed on the circular saw mounting seat 6, the bottom end of the vertical cylinder 3 is rotatably connected to the sawing machine 1, and a clamp 2 is respectively provided on the sawing machine 1 at both ends of the vertical cylinder 3. When cutting the workpiece, the cutting part of the workpiece is placed on the cutting table 4, and the two sides of the workpiece are clamped and fixed by the clamp 2 respectively, and then the vertical cylinder 3 is rotated so that the vertical cylinder 3 drives the cutting table 4 to rotate. At this time, the circular saw 28 on the cutting table 4 rotates with it, so as to adjust the lower cutting angle of the circular saw 28 relative to the workpiece. When it rotates to a suitable angle, the circular saw 28 is pressed down to cut the workpiece; In the above process, since the cutting table 4 is provided with a support plate 7 corresponding to the circular saw 28, and the support plate 7 is provided with a debris collection device composed of a hollow shaft 8, a rotating drum 13, a baffle 9, a roller brush 11, etc., after the angle is adjusted, the debris collection device is still arranged corresponding to the saw blade of the circular saw 28; when in use, the driving motor 14 is controlled to drive the rotating drum 13 to rotate, so that the rotating drum 13 drives any baffle 9 to rotate to the bottom, at this time, a part of the debris generated during cutting will be thrown toward the baffle 9 by the lower part of the saw blade, and because the front of the baffle 9 A baffle 9 and a roller brush 11 are arranged on the side, so that the debris will be intercepted by the hair bundles on the surface of the roller brush 11, so that the splashing of the debris can be greatly reduced; when each cutting is completed, the drive motor 14 is controlled to drive the drum 13 to rotate, so that the new baffle 9 is aligned with the cutting machine, and when the baffle 9 with the debris collected follows the drum 13 to rotate to the top, at this time, a water outlet pipe 17 on the drum 13 is aligned with the water outlet hole 16 on the hollow shaft 8, and the water injected into the inner cavity of the hollow shaft 8 by the water supply device will enter the vortex through the water outlet hole 16 and the water outlet pipe 17.

The sprayed water flow will flush the roller brush 11 along the direction tangent to the outer circle hub line of the roller brush 11. The waste water generated by the flushing will flow downward. The multiple guide plates 25 can guide the waste water flowing down from the top to the side of the baffle 9, so that the waste water will not splash on the roller brush 11 below. Finally, the waste water generated is collected by the water baffle 23 at the bottom of the baffle 9 and then discharged.
