Description

  The present invention relates to a configuration for increasing the efficiency of inheritance to a feed chain that transports cereals harvested by a harvesting unit of a combine to a threshing unit.

Conventionally, the lower part of the culm that has been caused by the pulling device arranged at the front part of the harvesting part and scraped by the scoring device arranged at the lower part is cut by the cutting blade device and arranged at the front, low, and rear heights. The upper conveying device to be installed conveys the tip side of the cereal, and the lower conveying device and the vertical conveying device disposed below the upper conveying device sandwich the cereal stock and convey it upward and rearward. The combine which has the cutting part of the structure which tilts and conveys the grain straw to perform, inherits the stock source of grain straw to a feed chain, and guides a tip into a threshing part is known.
Also, depending on the growth status of the cereal and the type of rice, the height of the cereal may vary, so you can rotate the rear end of the vertical conveyor and change the position of the stock that is inherited by the feed chain. The handling depth by the threshing / sorting device is set to an appropriate position.
Since it is difficult to carry the stock directly from the vertical conveying device to the feed chain, once the middle portion of the cereal is inherited to the auxiliary conveying device and the cereal is stably held in a horizontal state, the stock is transferred to the feed chain. It was configured to inherit the original.
