The invention discloses a self-propelled corn
combine harvester and belongs to the field of
agricultural machinery. The self-propelled corn
combine harvester comprises a working
chassis assembly and a harvesting
assembly. The working
chassis assembly consists of a power
system, a driving
control system, a walking
chassis system. The harvesting assembly is arranged on the working chassis and comprises a corn ear picking table, an ear picking table mounting rack, a primary ear
elevator, a secondary ear
elevator, an ear stripper, an ear throwing roller, an ear box, a stripper seed
recovery device and a
power transmission system which are mutually connected. The self-propelled corn
combine harvester is characterized in that a
straw chopper is arranged in front of a driving wheel of the walking chassis system, and is mounted under the ear picking table mounting rack in front of the driving wheel through a
chopper suspension device. Due to the structure optimized design, the
straw chopper is arranged in the front and is mounted in front of the driving wheel and under the ear picking table mounting rack, and the ear-picked
straw directly enters the chopper to be
cut. Therefore, the straw is prevented from being rolled by wheels, and the straw chopping quality is improved.
