[0028] Specifically, the dual carbon powder collecting assembly is provided with two groups, each group is designed in a semi-annular structure and corresponds to the left and right groups of carbon brushes 7 respectively.

[0029] Among them, each group of the dual carbon powder collection components includes a laterally arranged diverter collector 6 and a wrapped main collection component, the diverter collector 6 is installed on the outside of the carbon brush 7, and the first collection port 604 of the diverter collector 6 is located between two adjacent carbon brushes 7; the dust outlet of the diverter collector 6 is connected to the intake manifold 3 through the first connecting branch pipe 4; the design of the diverter collector adds multiple first collection ports near each carbon brush, and the first collection port adopts a large-diameter dust suction pipeline, which is adsorbed by a negative pressure fan with a large air volume, and the dust passing through the dust hood is collected for a second time in this way, which effectively improves the dust suction efficiency and the thoroughness of the adsorption.

[0030] Specifically, the main collection assembly includes a dust shield 5 and a dust collecting hood 11. The dust shield 5 is circular and covers the upper side of the carbon brush 7. A plurality of dust collecting hoods 11 correspond to the carbon brush 7 one by one and cover the inner periphery of the carbon brush 7. A plurality of second collection ports are provided on the side of the dust collecting hood 11 facing the carbon brush 7. The inner cavity of the dust collecting hood 11 is connected with the inner cavity of the dust shield 5. The dust outlet of the dust shield 5 is connected with the intake manifold 3 through the second connecting branch pipe 8. The design of the main collection assembly can adsorb the carbon powder generated on each carbon brush, but the adsorption effect will be affected by the distance between the dust collecting hood and the surface of the merge ring.
