DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a second reduction device for a threshing machine.

[0002]

2. Description of the Related Art Generally, as a transfer means for the second reduction in a threshing machine, a transfer case at the lower end of a cylindrical case containing an auger is connected to a transfer end of a second gutter. The second material (incompletely processed material including unthreshed grains) sent from the second conveyor into the successor case is simply lifted and transferred by auger, or A part in the transfer direction is formed by a group of teeth for providing a gripping action while transferring the second article, and a handling chamber, a processing chamber, and a sorting apparatus section are provided from a delivery port at an upper end of the cylindrical case. It is configured to reduce toward.

[0003]

Therefore, in the conventional transfer means for the second reduction, the second material in the almost incompletely processed state when it is taken over from the second conveyor is handled in the handling room, the processing room, or the sorting device. Part of the threshing equipment is returned to the required parts such as
As the load is applied, the engine speed drops and threshing equipment
It is easy for clogging to occur , especially for early rice harvesting or
Trends in combine threshing machines that process wet materials.
In order to avoid such inconveniences , it has been known that a part of the auger in the transport direction is formed by a group of teeth for providing a gripping action while transferring a second object. Have been . However , the second product was lifted and moved in the second reduction cylinder.
The reprocessing扱歯group and of the cutting edge gun structure which in transmission has a drawback of being inferior is elevating carrying capacity.

[0004]
