[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0021] Please see Figures 1-4 As shown, this utility model provides a technical solution: a milling cutter dust collection device, including a connecting pipe 1. Two sets of arc-shaped protective blocks 2 are hinged to both sides of the outer wall of one end of the connecting pipe 1. An opening and closing mechanism 3 for opening and closing the two sets of arc-shaped protective blocks 2 is provided on the top of the connecting pipe 1 through a mounting bracket. A dust collection hose 4 is provided at the end of the connecting pipe 1 away from the arc-shaped protective blocks 2. The end of the dust collection hose 4 away from the connecting pipe 1 is connected to a pipe on an external dust collection device. A dust collection port 101 is opened at one end of the connecting pipe 1. An installation strip 102 is fixedly connected to the bottom end of the dust collection port 101. The installation strip 102 is located away from the dust collection port 101. One end of the 01 is connected to a snap-fit ​​strip 103. Both ends of the mounting strip 102 are provided with insertion holes 104. Both ends of the snap-fit ​​strip 103 are fixedly connected to insertion blocks 105. The ends of the two sets of insertion blocks 105 away from the snap-fit ​​strip 103 are inserted into the two sets of insertion holes 104. The tops of both ends of the mounting strip 102 and the tops of both ends of the snap-fit ​​strip 103 are fixedly connected to mounting blocks. The mounting strip 102 and the snap-fit ​​strip 103 are fixedly connected to the mounting blocks by bolts and screws. The end of the connecting pipe 1 away from the dust suction port 101 is fixedly connected to a connecting port 106. The top end of the connecting port 106 is connected to the bottom end of the dust suction hose 4.

[0022] First, connect the end of the vacuum hose 4 away from the connecting pipe 1 to the pipe on the external vacuum equipment. Connect the external vacuum equipment to the connecting pipe 1 through the vacuum hose 4. At this time, the two sets of arc-shaped protective blocks 2 are in the open state. Then, attach the inner wall of the mounting strip 102 to the outer wall of the milling cutter mounting component. At this time, attach the snap-fit ​​strip 103 to the opposite side of the mounting strip 102 of the milling cutter mounting component, so that the two sets of inserts 105 are inserted into the inside of the two sets of insert holes 104. Then, lock the mounting blocks with bolts and threaded sleeves, thereby fixing the mounting strip 102 and snap-fit ​​strip 103 to the outer wall of the milling cutter mounting component. This makes it easy to fix the connecting pipe 1 and the milling cutter mounting component. The two sets of arc-shaped protective blocks 2 surround the outside of the milling cutter. At this time, the connection between the vacuum device and the milling cutter mounting component is completed.

[0023] The vacuum hose 4 is made of highly elastic and wear-resistant material, which has good flexibility and durability. It can withstand the negative pressure and suction generated during vacuuming to ensure the vacuuming effect. The design of the vacuum hose 4 allows for flexible swinging and adjustment to follow the movement of the milling cutter, ensuring that the vacuum hose 4 can always fit closely near the movement trajectory of the milling cutter and effectively collect the debris and dust generated during the milling process. In addition, the interface of the vacuum hose 4 is designed with a sealing device to ensure airtightness during the vacuuming process and avoid weakening the vacuuming effect.

[0024] As one implementation method in this embodiment, please refer to Figure 1 , Figure 3 and Figure 4 As shown, a cleaning brush 201 is fixedly connected to the bottom of each of the two sets of arc-shaped protective blocks 2. The cleaning brush 201 is made of soft silicone. The inner wall of the two sets of arc-shaped protective blocks 2 is in contact with the outer wall of the mounting strip 102 and the snap-fit ​​strip 103. The opening and closing mechanism 3 includes a cylinder 301 fixedly installed on the top of the connecting pipe 1. One end of the cylinder 301 is hinged to a folding frame 302 through a hinge. The two sides of the folding frame 302 away from the cylinder 301 are hinged to the top of the two sets of arc-shaped protective blocks 2.

[0025] When cylinder 301 is activated, its output pushes folding frame 302 to move. Folding frame 302 then rotates two sets of arc-shaped protective blocks 2, opening them for easy replacement of the milling cutter by maintenance personnel. When closed, the two sets of arc-shaped protective blocks 2 completely cover the outside of the milling cutter, protecting it from flying debris during high-speed rotation and improving safety. In addition, when closed, the two sets of arc-shaped protective blocks 2 also create a certain degree of sealing, preventing air leakage during dust collection and improving dust collection efficiency. Cleaning brush 201 cleans the debris generated during milling cutter operation.

[0026] Working principle: First, connect the end of the vacuum hose 4 away from the connecting pipe 1 to the pipe on the external vacuum equipment. The external vacuum equipment is connected to the connecting pipe 1 through the vacuum hose 4. At this time, the two sets of arc-shaped protective blocks 2 are in the open state. Then, by attaching the inner wall of the mounting strip 102 to the outer wall of the milling cutter mounting component, the snap-fit ​​strip 103 is attached to the opposite side of the mounting strip 102 of the milling cutter mounting component, so that the two sets of inserts 105 are inserted into the inside of the two sets of insert holes 104. Then, the mounting blocks are locked by bolts and threaded sleeves, thereby fixing the mounting strip 102 and the snap-fit ​​strip 103 to the outer wall of the milling cutter mounting component, which facilitates the fixed connection between the connecting pipe 1 and the milling cutter mounting component. The two sets of arc-shaped protective blocks 2 surround the outside of the milling cutter. At this time, the connection between the vacuum device and the milling cutter mounting component is completed.

[0027] When the dust collection device needs to be fixedly connected to the component where the milling cutter is installed, the external dust collection device is activated. The dust collection device absorbs the dust and impurities generated during the operation of the milling cutter through the dust suction port 101, and the cleaning brush 201 cleans the debris generated during the operation of the milling cutter. The dust and impurities are transported to the interior of the external dust collection device through the dust suction hose 4, thereby completing the cleaning of the dust and impurities generated during the operation of the milling cutter. When the milling cutter needs to be replaced or maintained, the cylinder 301 is activated. The output end of the cylinder 301 pushes the folding frame 302 to move. The folding frame 302 pushes the two sets of arc-shaped protective blocks 2 to rotate, so that the two sets of arc-shaped protective blocks 2 are in an open state, making it convenient for maintenance personnel to replace the milling cutter.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
