The invention provides a harvester. The harvester comprises a chassis assembly, a harvesting assembly, a conveying assembly, a collecting assembly, a driving assembly and a drive assembly. The harvesting assembly, the driving assembly and the collecting assembly are sequentially arranged on the chassis assembly, the conveying assembly stretches across the chassis assembly, the drive assembly provides power drive for mechanical motion of the whole machine, the harvesting assembly is used for harvesting corn ears and stems, and the conveying assembly is used for independently conveying whole corn plants, the harvested corn ears and the harvested corn stems to the collecting assembly. Compared with the prior art, the harvester is specially suitable for fresh corn planting environments in China, has the stem and ear harvesting function, can achieve non-row harvesting without manual assistance, and can achieve the full-automatic harvesting and collecting functions, and the cost is reduced; in addition, by means of the harvester, the ear damage rate is reduced, the recovery total quantity of the stems is increased, and income is increased.
