Abstract

The utility model relates to a multifunction portable rice wheat harvester. The utility model uses driving shafts as supporting points of its frame, and each component is installed on a shoulder-pole style frame. The multifunction portable rice wheat harvester mainly is composed of an engine, a driving assembly, a transporting paddy screw conveyer, a teasing pulling pressing standing grain roller, a threshing roller and a manipulating pole. The adoption of shoulder-pole style frame for mounting the components makes the utility model convenient to be operated, be lifted fore and after and go up and down the field. The way that the teasing pulling pressing standing grain half-feeding rollers cooperate with each other to thresh is adopted, which reduces the public known devices of the harvester, such as the header, the screw conveyer, the straw transporting device and the thresher, that is to say, the volume and the weight of the complete machine is reduced. The utility model realizes the goal of the light-duty type rice wheat harvester.
