DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foliage processing machine that extracts and collects only the foliage of a subterranean crop such as sweet potato.

[0002]

2. Description of the Related Art When harvesting rhizome crops such as potatoes and sweet potatoes, a pre-processing operation is first performed in which only the above-ground parts (foliage) are extracted and removed, and then the underground parts (potatoes) are dug up and collected. Although the method is adopted, since the pre-processing work by hand becomes a heavy labor in a middle waist posture, a foliage processing machine that performs the pre-processing work with less labor has been developed (for example, see Japanese Utility Model Publication No. 6-8660). ).

[0003] The conventional foliage processing machine has a scraping device for scraping the foliage of potatoes or the like backward, and a foliage scraped by the scraping device is nipped by a front starting end and transported upward and backward. And a transfer device that inherits the transfer material from the transfer device and lifts and transfers it further upward and rearward, and a transfer product that is delivered from a transfer terminal end of the upper transfer device. A processing work unit including a collecting and discharging device that collects and discharges a predetermined amount each time is collected is mounted on the self-propelled vehicle.

[0004]

According to the above-mentioned foliage processing machine, the foliage of the subterranean crop planted in the field is scraped by the scraping device as the self-propelled vehicle advances, and the nipping and transferring device is used. When the foliage is vine-like, which grows as if crawling on the ground, or when it lays down along the ground, the foliage of adjacent rows is intertwined with each other. However, in the conventional foliar processing machine, since the foliage of the adjacent rows is not completely separated and entangled with each other and transferred from the scraping device to the nipping and transporting device and transported, a large transport resistance is generated. It is difficult to pull out only the foliage part by hanging it, and it is difficult to unintentionally pull out the underground part (potato) in the transfer area of the pinch transfer device and further to the foliage and underground part of the adjacent row. There was a problem that could be.

[0005]

Accordingly, the present invention is directed to a vine-like plant whose foliage grows over the ground and a rhizome crop that lays down along the ground.
