As the milling cutter head 6 descends, the cleaning tube 8 brings the connecting tube 9 to squeeze the spring 10, and the top of the connecting tube 9 passes water inward to spray water from the spray hole 801 toward the surface of the milling cutter head 6. During the rotation of the milling cutter head 6 for milling operations, ordinary debris that is not entangled in the milling cutter head 6 will be removed under the action of centrifugal force. , and the debris or wire scraps entangled on the outside of the milling cutter head 6 will leave the milling cutter head 6 under the impact of the water flow sprayed from the spray hole 801, and the debris or wire scraps entangled on the outside of the milling cutter head 6 will rotate close to the cleaning tube 8, thereby being blocked by the cleaning tube 8 and extending into the groove 802, and being blocked and pulled by the cleaning tube 8 and the cutting and pulling of the blade 11 in the groove 802, and the water spraying is combined to pull out the wire scraps entangled on the surface of the milling cutter head 6, thereby ensuring the cleanliness and effectiveness of the milling process of the milling cutter head 6, avoiding affecting the accuracy of subsequent milling, and thus improving the quality of the milled product.

[0023] In the present invention, the top of the connecting pipe 9 is connected with a connecting pipe 13 of a hose structure, a through hole corresponding to the position of the connecting pipe 13 is provided on the lifting frame 3, a slider 14 is fixed to the top of the outer wall of the connecting pipe 9, a spring 10 is fixed between one end close to the connecting pipe 9 and the slider 14, an L-shaped limit frame 12 is installed below the lifting frame 3, a sliding hole corresponding to the position of the connecting pipe 9 is provided at the bottom of the limit frame 12, the outer wall of the connecting pipe 9 is in sliding contact with the inner wall of the sliding hole, the slider 14 is located above the sliding hole, two vertically extending limit strips 121 are fixed to the side of the limit frame 12, the slider 14 is in sliding contact with the side wall of the limit frame 12 and the two limit strips 121, so that the cleaning pipe 8 and the connecting pipe 9 can move in the vertical direction through the limitation of the slider 14 and the connection of the spring 10, so as to ensure that the cleaning pipe 8 is close to the milling cutter head 6 as the milling cutter head 6 descends.

[0024] In the present invention, the end positions of the connecting pipe 9 and the cleaning pipe 8 near each other are horizontally extended, a connecting box 15 is arranged between the connecting pipe 9 and the cleaning pipe 8, one end of the connecting pipe 9 is fixedly connected with one end of the connecting box 15, a through hole is opened at the end of the connecting box 15 near the cleaning pipe 8, the outer wall of the cleaning pipe 8 is in sliding contact with the inner wall of the through hole, a sliding sleeve 16 is arranged at the end of the outer wall of the cleaning pipe 8 near the connecting pipe 9, a spring 17 is connected between the sliding sleeve 16 and the inner wall of the connecting box 15, and the outer wall of the sliding sleeve 16 is in sliding contact with the inner wall of the connecting box 15. During the process of keeping the milling depth unchanged, water in the connecting pipe 9 enters the connecting box 15 and then enters the cleaning pipe 8 and is sprayed out from the spray hole 801. When the water in the connecting pipe 9 enters the connecting box 15, the part of the cleaning pipe 8 parallel to the milling cutter head 6 will be brought into contact with the milling cutter head 6 under the impact of the water flow, so that the wire scraps entangled on the surface of the milling cutter head 6 can be pulled out through the cleaning pipe 8 in a fixed position, thereby improving the cleaning effect of the milling cutter head 6 during the milling process, thereby improving the milling effect and the quality of the finished product after milling.

[0025] In the present invention, the sleeve 16 is rotationally connected to the outer wall of the cleaning tube 8 by a torsion spring, a protrusion 18 is fixed to the outer wall of the cleaning tube 8 near the sleeve 16, and the end of the sleeve 16 is fixed with limit blocks 19 on both sides of the protrusion 18. When the cleaning tube 8 is close to the milling cutter head 6, the milling cutter head 6 rotates close to the cleaning tube 8 with the entangled wire chips, and the wire chips can deflect the cleaning tube 8 to a certain extent to buffer the direct impact force, and then in the process of the deflection of the cleaning tube 8, the wire chips gradually separate from the milling cutter head 6, and after separation or when the wire chips are away from the cleaning tube 8, the cleaning tube 8 is reset under the action of the torsion spring, thereby improving the cleaning effect of the wire chips entangled on the surface of the milling cutter head 6 by the swinging cleaning tube 8.

[0026] In the present invention, positioning rings 20 are installed on both sides of the outer wall of the connecting pipe 9, and the inner wall of the positioning ring 20 is slidably connected with a horizontally placed movable rod 21, and the same positioning frame 22 is installed between the ends of the two movable rods 21 close to the connecting box 15, and a magnetic block 23 is installed in the positioning frame 22. The bottom end of the magnetic block 23 is close to the top of the connecting box 15, and the magnetic block 23 is magnetically adsorbed to the top of the sliding sleeve 16. A connecting ring 24 is installed on the outer wall of the movable rod 21, and a spring 25 is connected between the connecting ring 24 and the positioning ring 20. A contact block 26 with a spherical structure is fixed at one end of the movable rod 21 away from the magnetic block 23. A limiting member 27 is provided on the side of the connecting pipe 9 away from the connecting box 15, and an electric telescopic rod 28 is connected to the top of the limiting member 27. The electric telescopic rod 28 is fixed to the limiting frame 12, and the side of the limiting member 27 facing the contact block 26 is set to an inclined surface, and the inclined surface faces the contact block 2 One side of 6 is inclined upward. During the processing of continuous milling and changing milling depth on the same accessory, especially for the increase of milling depth during milling, it is easy to cause the surface debris of the milling cutter head 6 to fall before it is thrown out, thereby affecting the milling accuracy. In the design of the present application, when the lifting frame 3 descends with the milling cutter head 6, the bottom end of the cleaning pipe 8 is always limited by the surface of the accessory, so that the cleaning pipe 8 and the connecting pipe 9 move upward relative to the limiting frame 12. At this time, the contact block 26 contacts the inclined surface and moves upward, so that the contact block 26, the movable rod 21 and the magnetic block 23 are pushed toward the cleaning pipe 8 through the limiting member 27, thereby actively bringing the cleaning pipe 8 close to or even fitting the direction of the milling cutter head 6, so as to actively clean the surface of the milling cutter head 6 during the descent, so as to improve the cleaning effect of the milling cutter head 6 during the depth change process, thereby improving the milling quality during the depth change milling process.

[0027] In the present invention, the limiter 27 is provided with a connecting block 271 and an extrusion block 272, the connecting block 271 is connected to the electric telescopic rod 28, the extrusion block 272 is arranged at a side position of the connecting block 271 close to the contact block 26, and the side of the extrusion block 272 close to the contact block 26 is arranged to be an inclined surface, and the inclined surface is inclined upward toward the side close to the contact block 26; a pressure sensor is connected between the extrusion block 272 and the connecting block 271, and the contact block 26 is in the middle position of the inclined surface in a normal state, and the extrusion force between the extrusion block 272 and the connecting block 271 at this time is recorded as the initial extrusion force Force, when the milling depth changes, the milling head 6 will be controlled to rise and fall, and the pressure at the corresponding position of the pressure sensor will change; after the lifting operation is completed, the monitoring value of the pressure sensor is obtained and adopted, and the electric telescopic rod 28 is controlled to lift and lower with the limit member 27 according to the monitoring value, until the monitoring value of the pressure sensor is restored to the initial extrusion pressure; so that after a single milling depth change of the milling head 6, the magnetic block 23 can still actively move with the cleaning tube 8 to perform active cleaning operations during the next depth change process, thereby improving the milling effect of the equipment for continuous long-term milling operations.

[0028] Example 2: Reference Figure 1-Figure 8 , a milling processing equipment for accessories for environmental protection, based on Example 1, a distance sensor is installed in the connection box 15 near the connecting pipe 9, and the distance sensor is used to monitor the distance between the sliding sleeve 16 and the end of the connecting pipe 9 in real time. Under normal conditions or when the cleaning pipe 8 is close to the milling cutter head 6, the monitoring data of the distance sensor will be greater than the reference value. However, when there are too many debris or wire scraps on the surface of the milling cutter head 6 and it is difficult to clean them quickly, the milling cutter head 6 rotates to a position close to the cleaning pipe 8, which will not only deflect the cleaning pipe 8, but also squeeze the cleaning pipe 8 toward the connecting pipe 9 after the cleaning pipe 8 deflects to the maximum angle, so that the spring 17 is compressed, that is, the monitoring value of the distance sensor decreases and is lower than the reference value. At this time, the milling cutter head 6 needs to be raised to separate it from the accessory, and the milling operation can be continued after the milling cutter head 6 is actively cleaned, thereby improving the milling effect.

[0029] In the present invention, for operations with a constant milling depth, the monitoring data of the pressure sensor and the distance sensor during the milling process are uploaded to the processor for comprehensive analysis. If the monitoring value of the distance sensor is lower than the reference value, there is too much debris on the surface of the surface milling cutter head 6 and it needs to be actively cleaned. If the monitoring value of the pressure sensor is higher than the initial pressure value, that is, the magnetic block 23 is squeezed and applied toward the limit member 27 under the action of the magnetic attraction between the magnetic block 23 and the sleeve 16, there may be too much debris on the surface of the surface milling cutter head 6 and it needs to be actively cleaned. Through the setting of the overall cleaning component 7 and the monitoring setting of the pressure sensor and the distance sensor, the debris entanglement condition on the surface of the milling cutter head 6 can be accurately and effectively judged, so as to make timely cleaning and adjustments to ensure the milling accuracy of continuous milling operations and improve the quality of finished products.
