The invention discloses a header for a stalk and ear harvesting type corn harvester. The header comprises an ear harvesting header, a straw harvesting header and a lower main shaft, wherein the ear harvesting header comprises a left small elevator, a right small elevator, a left small auger, a right small auger, a left ear picking mechanism and a right ear picking mechanism; the left ear picking mechanism comprises a first left ear picking unit, a left middle ear picking unit and a second left ear picking unit, and the right ear picking mechanism and the left ear picking mechanism are symmetrically arranged; the first left ear picking unit comprises a first left gearbox, and the second left ear picking unit comprises a second left gearbox; and the left small elevator, the left small auger and the left ear picking mechanism are in transmission connection with a left first shaft of the header, and the right small elevator, the right small auger and the right ear picking mechanism are in transmission connection with a right first shaft of the header. The problems that a transmission chain of an existing header is prone to heating and breaking, a transmission shaft is prone to bending, and transmission reliability of the header is not high are solved, and the header is more reasonable in transmission arrangement, even in load distribution, stable in operation and high in reliability.
