Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a technology for discharging waste straw and grain storage bags generated in conjunction with combine harvesting operations into a field. To provide a combine harvester capable of discharging grain storage bags in an orderly manner and in a well-organized manner to a field, and at the same time sufficiently preventing the discharging bags from being soiled by mud etc. especially during work in wet fields.

The combine harvester according to the present invention is provided with a sensor that detects the position of the group of collected waste straw released into the field during the previous process, and based on the detection operation of this sensor, the grain storage bag is placed on the detected group of collected waste straw. The present invention is characterized by being equipped with a device for automatically discharging a group of straw, as well as a device for automatically discharging a group of concentrated waste straw similar to the current type.

In other words, there is a conventional technology that releases waste straw groups and grain storage bags based on the detection of materials released into the field during the previous process, but in this conventional technology, the grain storage bags and waste straw groups are were released in a completely unrelated manner, so when considering the collection work for the entire field, collection work for the release bags and collection work for the released waste straw clusters had to be performed separately, which led to a reduction in collection work efficiency. is low.

Furthermore, especially when working in wet fields, there is a fear that the grain storage bags and stored grains released into the field will be contaminated with muddy soil or muddy water. In contrast, according to the present invention, based on the detection of the released waste straw group, the grain storage bag and the waste straw group are released together in close proximity to each other, so that the collection work of the released bag and the released waste straw group is performed. This can be done with less effort, and it is possible to improve the efficiency and save labor of the waste collection work in Odaiba as a whole.

Moreover, by utilizing the ability to release the grain storage bag and the waste straw group in a well-organized manner in this way, and by releasing the grain storage bag onto the waste straw group, even when working in wet fields. Therefore, it is possible to prevent the release bag and the stored grain from being contaminated by mud and muddy water. Therefore, the present invention streamlines subsequent collection work by discharging the grain storage bag and the waste straw group into the field in an orderly manner and in a state where the grain storage bag is less likely to be soiled by mud or the like. In addition, it has now been possible to provide a combine harvester that can make the subsequent handling of recovered grain advantageous.
