Abstract

PROBLEM TO BE SOLVED: To control the threshing depth of the cereal stems in a threshing mechanism by changing the position relaying to the feed chain of the threshing mechanism, as the cereal stems cut by the cutter are conveyed and carry out the movement for controlling the threshing depth in the cereal stem conveyer with a simple mechanical constitution. SOLUTION: The cereal stem conveyer 4 which conveys the cereal stems cut by the cutter and feeds them the feed chain 3 is equipped with a stem foot conveyer 6 which swings the starting side of conveying so as to adjust the threshing depth around the swinging shaft 5 and the ear tip conveyer 8 which swings the end side around the swing shaft 7. The swings of both conveyers 6, 8 are interlocked with a single motor M based on the detection of the threshing sensor.

1. A grain stalk transport device 4 for transporting grain stalks cut by a cutting device 1 and supplying it to a feed chain 3 of a threshing device 2.
The starting end of the transfer is adjusted to a pivot shaft 5 so as to adjust the threshing depth.
And the tip end transfer device 8 that swings with the end side as the swing shaft 7. The swing of both transfer devices 6 and 8 is handled based on the detection of the depth sensor S <b> 1. Combine harvesting grain culm conveying device linked by a single motor M.
