The invention discloses a tangential-longitudinal axial type grain combine harvesting and bundling duplex operation
machine which comprises a grain
cutting and conveying
system, a seed
threshing and separating
system, a seed cleaning device, a seed collecting and storing
system, a
straw compressing and bundling device, a
chassis walking system and a driving operation system. When the duplex operation
machine harvests grain in the field, firstly, the grain
cutting and conveying system cuts stalks of grain and conveys the grain to the seed
threshing and separating system, straws where seed
threshing and separating are conducted are compressed and bundled through the
straw compressing and bundling device, seeds obtained through threshing are cleaned through the seed cleaning device, and seeds obtained through cleaning are conveyed to a grain tank through the seed collecting and storing system. The duplex operation
machine can meet the requirements for harvesting seeds of rice and wheat and compressing and bundling threshed straws, and has the advantages of being high in work efficiency, stable in
work performance, simple in work procedure and capable of saving time and labor.
