The invention discloses a milling and excavating head of a milling and excavating machine. The milling and excavating head of the milling and excavating machine comprises a rack and cylindrical bases arranged on two sides of the rack, wherein a plurality of main cutting teeth are arranged and distributed on the circumference surface of each cylindrical base in a spiral manner; the orientation range of the main cutting teeth is gradually changed one by one in a spiral manner; one part of main cutting teeth near the inner side of each cylindrical base face the inner side; one part of main cutting teeth near the outer side of each cylindrical base face the outer side. The milling and excavating head of the milling and excavating machine has the advantages that the orientation range of the main cutting teeth is gradually changed one by one in a spiral manner; one part of main cutting teeth near the inner side of each cylindrical base face the inner side; one part of main cutting teeth near the outer side of each cylindrical base face the outer side; the main cutting teeth on the cylindrical bases cover face towards multiple directions; when the milling and excavating head is used for breaking the base materials, the milling and excavating head is capable of breaking the base materials on the front surface of the milling and excavating head and simultaneously breaking the base materials in the middle position and at two sides of a machine base; the overall milling and excavating efficiency is improved.
