2. Description of the Related Art In order to harvest potatoes grown in the soil, efficient harvesting cannot be performed unless vines on the ground are removed in advance. This is done by a sweet potato extractor,
It has a structure in which a potato vine crawling on the ground is run while being drawn out and discharged at a predetermined width (drawing width). By the way, since potato vines proliferate in layers on the ground and are tightly entangled with each other to form a net, the drawing width cannot be set unless they are accurately divided.

[0003] For this reason, the potato vine extractor is equipped with some sort of vine cultivation device. However, in the case of the stalk culm harvester equipped with many potato vine extractors, the vine vines are not separated from each other. The entanglement was so severe that the resistance was too great to spread the vines, and the vines could not be divided enough, reducing accuracy and efficiency. Therefore, the present applicant has provided a method of cutting the vine at the outer end of the drawing width with a cutting device comprising a vertical clipper blade (Japanese Patent Application No. 7-207566), and has obtained a corresponding effect.

[0004]

In this prior art as well, the cutting device is provided with a guide mechanism for guiding the vine to a certain extent. It was found impossible to guide all the vines at the border of the to the cutting device. It has also been found that the vine itself is tough, and that it requires a very large cutting force to cut all the vines of considerable thickness. The present invention is intended to solve such a problem, in which a part of the vine is divided and the remaining part is cut, so that the vine at the boundary of the drawing width is surely divided or cut. is there.

[0005]

Under the above object, according to an aspect of the present invention is to minute vine outer ends in minutes vine apparatus of a predetermined width of vine sweet potato to flourish on the ground, cutting width and cut with the cutting device In a potato vine extractor that runs while pulling out and discharging the vines within the width of the drawing, the split vine device is moved forward and upward from the cutting device through the upper layer of the vine at the outer end of the width of the drawing. Extended to
A vine spreader, and a vine plate that exists under the downward projection of the vine rod and extends downward and forward from the cutting device in the lower layer. Provided.

According to the present invention, by taking the above measures, the upper and lower portions of the vine at the outer end (boundary) of the drawing width are separated by the vine-dividing device, and the middle portion is cut by the cutting device. Therefore, the two devices work as a complement to each other, so that neither device is overwhelmed, and it is easy and reliable to separate and cut.
