[0018] The effects achieved by the above components are as follows: By setting up the dust reduction component, first, the water source is put into the liquid storage box through the feed pipe. At this time, the electric telescopic rod is started, so that the electric telescopic rod pushes the round rod to move left and right along the inside of the liquid storage box, causing the round rod to push the piston plate to move along the inside of the liquid storage box towards the direction close to the round pipe, so that the piston plate squeezes the water source inside the liquid storage box during the movement, enabling the water source to enter the atomizing pipe through the round pipe, and then forming a mist and spraying out under the action of pressure and the small pores on the atomizing pipe, so that the atomized water sprinkles on the collection box to wet the debris and impurities, thereby achieving the dust reduction treatment of the debris and impurities in the collection box, reducing the situation where the debris and impurities in the collection box float under the influence of air flow, resulting in the debris and impurities flying out of the collection box and adhering to the inner wall of the rectangular cylinder, affecting the cleanliness inside the rectangular cylinder, and further improving the collection effect of debris and impurities.

[0019] The beneficial effects of the present invention are as follows: 1. By setting up a mechanism to clean the tool bit that is reinserted into the inside of the shield body, it reduces the situation that when the tool bit is reinserted onto the tool rest, debris and impurities are brought into the inside of the shield body together, resulting in the accumulation of debris and impurities inside the shield body or on the tool rest, which affects the service life of the tool rest and the cleanliness inside the shield body. It improves the convenience of cleaning the tool bit and the cleanliness of the tool bit surface.

[0020] 2. When the manipulator deposits the used tool bit into the tool magazine inside the shield housing through the shield outlet, the tool bit is inserted into the internal gear ring, causing multiple sponge blocks to fit against the surface of the tool bit. At this time, the motor is started, causing the motor to drive the gear to rotate, which in turn drives another gear to rotate. Under the action of the snap ring, the gear ring rotates around the rectangular frame as the center. During the rotation of the gear ring, it drives multiple sponge blocks to rotate. During the rotation of the multiple sponge blocks, they fit against the surface of the tool bit and sweep off the impurities and debris adhering to its surface, thus achieving rapid cleaning of the tool bit. When the impurities and debris on the tool bit are swept off, the blower is started, causing the blower to provide suction to the wind hood through the pipeline. The wind hood sucks the scattered debris and impurities into the pipeline and discharges them into the collection box inside the rectangular cylinder for storage, thus achieving rapid collection and treatment of the debris and impurities.

[0021] 3. Water source is put into the liquid storage box through the feed pipe. At this time, the electric telescopic rod is started, causing the electric telescopic rod to push the round rod to move left and right inside the liquid storage box. The round rod pushes the piston plate to move towards the direction close to the round pipe inside the liquid storage box. During the movement of the piston plate, it squeezes the water source inside the liquid storage box, causing the water source to enter the atomizing pipe through the round pipe. Then, under the action of pressure and the tiny pores on the atomizing pipe, it forms a mist and sprays out. The atomized water sprinkles onto the collection box to wet the debris and impurities, thus achieving the dust reduction treatment of the debris and impurities in the collection box.
