The invention provides an inclined plate ball groove drilling mechanism of a corn harvester
threshing device. The inclined plate ball groove drilling mechanism aims at solving the problem that due to the fact that a semi-mechanized corn harvester mechanism on the market does not have the
threshing function, the development requirement can not be met. The inclined plate ball groove drilling mechanism of the corn harvester
threshing device is characterized in that a driving mechanism is fixed to the right side of a rotating shaft, the rotating shaft is sleeved with a left bearing pedestal and a right bearing pedestal, the left bearing pedestal and the right bearing pedestal are fixed to a left
machine frame plate and a right
machine frame plate, an upper angle type support and a lower angle type support are arranged on the upper
machine frame plate and the lower machine frame plate, an upper inclined type positioning plate and a lower inclined type positioning plate are fixed to the upper angle type support and the lower angle type support respectively, a ball groove inclined plate is arranged on the right side of the rotating shaft in a sleeving mode and fixed to the upper inclined type positioning plate and the lower inclined type positioning plate, a ball groove is formed in the ball groove inclined plate, a
rotating disc is fixed to the left side of the rotating shaft, a clamp is arranged on the
rotating disc, a
drill bushing is arranged on the right side of the clamp, the front end of a
drill bit is sleeved with the dill
bushing, the rear end of the
drill bit is connected with a swing rod, and a swing head is arranged at the
tail end of the swing rod and placed in the ball groove of the ball groove inclined plate. The inclined plate ball groove drilling mechanism has the direct threshing function, and full
mechanization of the corn harvester mechanism is achieved.
