Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a root vegetable harvesting method and a root vegetable harvesting apparatus, for example, to harvest root vegetables such as carrots and radish.

[0002]

2. Description of the Related Art Heretofore, most of the root vegetable harvesting devices of this kind, for example, the harvesting device for harvesting carrots, dig up one or two articles of ginseng and pinch the foliage part of the ginseng. A configuration is known in which the rhizome is hung and conveyed upward and rearward, and the foliage of the carrot is cut from a predetermined position with a cutter at the conveying end, and the rhizome is dropped and harvested. ing. In addition, the ginseng cultivation method is usually 4 to 8 rows per 1 ridge with an interval of 15 cm inside and outside.

[0003]

In the conventional harvesting device for harvesting carrot described above, depending on the harvesting time, for example,
When carrots are harvested in winter, the leaves of the ginseng are often dead, so even if you dig up the ginseng, it is difficult to transport the ginseng by pinching the leaves and hanging the rhizome. However, there is a problem that carrots cannot be continuously harvested in such cases. In addition, since 1 to 2 rows of ginseng are harvested from among 4 to 8 rows grown in one ridge, adjacent ginseng may be damaged by excavated bodies and running bodies. There is also.

The present invention has been made in view of the above points, and a root vegetable harvesting method and a root vegetable harvesting method capable of continuously harvesting root vegetables despite the situation that the foliage of the root vegetables is dead and cannot be sandwiched. The purpose is to provide the device.

[0005]

A method for harvesting root vegetables according to claim 1, wherein a step of placing the dug root vegetables in a state preceded by the rhizome and transporting them while shaving off the soil. The process of raising the roots while transporting them and carrying them out while changing the posture so that the rhizome is upward and the leaves are downward, and the roots of the root vegetables are sandwiched and transported while aligning the cutting positions of the stems and leaves. And a step of cutting the foliage of the root vegetables from the cutting position. Through these series of steps, the rhizomes of root vegetables obtained by cutting the foliage of the root vegetables are continuously harvested.

In the root vegetable harvesting apparatus according to the second aspect of the present invention, the excavated body for excavating the root vegetable and the root vegetable from the excavated body are placed in a state in which the root portion precedes the excavated body.
