It is a technology that can be used as a crop harvester for seeds.

[0002]

2. Description of the Related Art Harvesting a seed-bearing crop that takes the seeds of a crop planted in a field is done by assuming that this crop is, for example, an onion. It was a manual harvesting and harvesting work using a sickle.

[0003]

[Problems to be Solved by the Invention] The culm harvesting work of onion seed crops requires labor, labor and a long working time by manually cutting with a sickle or the like and performing the harvesting work. However, it is intended to mechanize this.

[0004]

To this end, according to the invention as set forth in claim 1, the present invention provides a cutting device 4 for cutting a crop with seeds on a front part of a traveling chassis 3 of a traveling vehicle 2.
A crop harvester with seeds, characterized in that a transfer device (5) for transferring the crop culm with cut seeds to the rear and a storage means (6) for taking over and storing the crop culm with harvested seeds are provided above the traveling chassis (3). It is a machine configuration.

According to a second aspect of the present invention, the storage means 6 is not installed in the front portion of the driving operator so as not to obstruct the visual field of the driving operator. It was used as a crop harvester for seeds.
In the invention according to claim 3, the mowing device 4 is
The crop harvester for seeds according to claim 1 or 2, wherein the crop harvester is provided so as to be vertically movable.

[0006]

According to the invention described in any one of claims 1 to 3, the onion planted in the field is used, and the harvesting work of the crop culm with seed of the crop with seed, which is the onion, is carried in the field with the vehicle 2 The traveling vehicle 2 at this time.
Reaping device 4 provided at the front of the traveling chassis 3 of the vehicle so as to be vertically movable.
Based on the culm length of the crop culm with seeds, the vertical position is set to a predetermined position, and the traveling vehicle 2 is caused to travel through the planting section of the field by the operation of the driving operator. A predetermined position of the crop culm is cut and mowed, and the crop culm with the mowed seeds is taken over by the transfer device 5 and transferred by the transfer device 5 to obstruct the driver's view of driving above the traveling chassis 3. The storage means 6 is installed at a position that does not become For example, it is supplied and stored in a large storage bag,
