Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a burdock which has a pair of left and right digging gobs that are long in the front and rear and face each other in an inverted eight-shape when viewed from the front of a towing vehicle such as a tractor or a self-propelled vehicle. So that a pair of excavators can pass through on both sides of the row of burdock cultivated in the field where the burdock is cultivated. The present invention relates to a burdock harvesting device that picks up and harvests a burdock in a cultivation row that has been raised by holding the soil from the left and right with a pair of excavated gobs.

[0002]

2. Description of the Related Art The burdock harvesting work used to be
First, in the root row on one side of the row of burdock cultivated in the field, a trencher is used to excavate a deep groove,
Then, a worker enters the groove, and the soil around the root of the row of burdock root is collapsed into this groove to release the root of the burdock from the surrounding soil, and from that state , It is done by grasping the head of the root of the burdock and pulling it out.

However, this means is inefficient in the work of excavating the burdock digging trench by the trencher, so that the overall work efficiency cannot be improved, and as described above, it is long in the front and rear. Burdock in the field by mounting the excavator composed of a pair of left and right excavated gobs facing each other in a reverse octagonal shape in front view on a tractor body or a self-propelled body.
