Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a combine harvester.

[Conventional technology]

Conventionally, when the threshed straw of wheat is used for feed, used as mixed material for walls and bricks, or used for fertilizer, etc., it is used to crush it into a fine and flexible state that is easy to bend. equipment was used, which had the following inconveniences:

[Problem that the invention seeks to solve]

That is, when reaping and harvesting wheat and also crushing the straw in the threshing section, the reaping and harvesting work and the crushing process must be performed separately, resulting in poor work efficiency.

The first aspect of the present invention is to provide a machine that can efficiently perform reaping harvesting and crushing of threshing straw, and the second aspect of the present invention is to provide a machine that can also advantageously collect crushed waste straw. .

[Means for solving problems]

The combine harvester according to the first invention is characterized by being equipped with a waste straw crushing device for crushing the threshing straw from the threshing section, and its functions and effects are as follows.

[For production]

Equipped with a waste straw crushing device, it becomes possible to crush the threshing straw while harvesting the husk culms.

〔Effect of the invention〕

Since the reaping and harvesting of the husks and the crushing of the threshing part straw can be done at the same time, these operations can be carried out efficiently, and when using the wheat straw as mentioned above, the threshing part straw is made into a property that can be used at the same time as the reaping and harvesting. It has become advantageous to collect and use threshing straw.

The combine harvester according to the second aspect of the present invention is provided with a wandering straw crushing device for crushing threshing straw from the threshing section, and a bagging section for collecting crushed straw from the waste straw crushing device. Its functions and effects are as follows.

[For production]

Equipped with a waste straw crushing device, it is possible to crush the straw in the threshing section while reaping and harvesting the husk, and the crushed waste straw can be easily packed into bags at the same time as it is discharged from the waste straw crusher. Collection is made possible by the bagging section.

〔Effect of the invention〕

Not only can the work of reaping and harvesting the husks and the action of crushing the straw in the threshing section be carried out efficiently at the same time, but the bagging section also makes it easier to collect the crushed waste straw, making it possible to remove the waste straw from wheat straw. As mentioned above, when using the threshing part, the straw is reaped and harvested to make it usable at the same time.
Moreover, it is advantageous in terms of processing and recovery when collecting and using the threshing straw, as it can be packed in bags.
