The invention discloses an electric generator collecting assembly comprising special brush lifting devices, a conductive plate, an insulating plate, a fan cover, a fixed frame, an insulating baseplate, a base, air warming resistors, insulating fixed bases, a connecting bar, a connecting bar external cover, an assembly external cover and an external cover door. The special brush lifting devices areinwardly connected with the conductive plate and the insulating plate in turn through bolts. The cross section of the insulating plate is provided with the fan cover which is connected with the insulating plate through the bolts. The fixed frame, the insulating baseplate and the base are connected on the lower end of the conductive plate in turn. The air warming resistors are arranged on the external end of the base. The insulating fixed bases and the connecting bar are arranged on the internal end of the base. The electric brush components can be taken out to be replaced under the normal operation state of the machine through the special brush lifting devices; and the heat radiation difficulty of the assembly can be solved by the separate design of the connecting bar and the conductive plate of the collecting assembly. The electric generator collecting assembly is simple in structure and easy to operate and has excellent word of mouth after placing on the market.
