TECHNICAL FIELD OF THE INVENTION
The present invention relates to a soybean harvester.
[0002]
[Prior art]
When harvesting green soybeans, the green soybeans planted in the field were pulled out of the stalks from the soil and transported to the harvest hut, where the green soybeans were harvested from the stems.
[0003]
Through the development and research of the applicants, a green soybean stripping device that automatically and efficiently removes green soybeans from stalks has been developed, and an automatic sorting device that sorts and stores the green soybeans that have been removed has also been developed. The work efficiency has been significantly improved as compared with the past.
[0004]
[Problems to be solved by the invention]
However, there is no automatic harvester that removes green soybeans from the stalks while harvesting green soybeans that have been planted in the field so far. is there.
[0005]
In rice cultivation and the like, there are automatic harvesters that combine several rice stalks like a combine, cut them with a cutter, and convey this to the rear to thresh, but soybeans are as fruity as the roots of the stalks just below the soil surface. Since certain green soybeans are used, the combine of rice action cannot be applied as it is, and since the threshing structure is different, it cannot be used as a green soybean harvester as it is.
[0006]
In this way, green soybeans are soaked so that they are as close as possible to the surface of the soil.Because it is necessary to secure a handle portion in the harvesting work after mowing, it is also possible to simply mow with a scythe or an automatic mower. Rice combine harvesters could not be used, and in the end it was the situation that each individual worker pulled out the whole root and carried it to the harvest hut.
[0007]
Therefore, in the green soybean farmers, there are originally few workers, and this extracting work is required at the time of harvesting. Therefore, despite the growing demand in recent years, the green soybean planting area cannot be expanded.
[0008]
The present invention finds such a current situation in the development, manufacture, and sale of a soybean stripping device, and solves this problem.The present invention follows the basic configuration of an existing rice crop combine in terms of crop harvesting. In addition, while holding and transporting green soybeans, the roots of the stalks or the roots in the soil can be automatically cut as much as possible to efficiently and smoothly cut and harvest green soybeans, and the existing green soybean stripping device is incorporated into the main body. It is possible to provide a groundbreaking green soybean harvesting machine that can automatically harvest and harvest green soybeans without much effort even with a large planting area, even when harvesting from the stalks is automatically performed.
