This means that when harvesting a rooted rhizome crop, the root that extends below the crop is cut at the root cutting part provided on the fuselage, and at the same time, the soil around the crop is softened, and the conveyer pulls out a certain length of the foliage. It is cut into pieces and stored in a storage container.
[0003]
[Problems to be solved by the invention]
In the prior art, the cutting portion is cut into a bulb portion and a foliage portion, and the separated foliage portion becomes heavier at the upper portion, falls forward with the holding portion as a fulcrum, falls off at the end of the conveyor, falls forward, and the extraction portion is removed. There was a problem that the foliage was covered and the work efficiency was reduced. Further, in the case where the rhizome is covered with a multi-sheet and cultivated, there is a problem that the multi-sheet is simultaneously pulled up at the time of extraction and is rolled up on a transport conveyor. Further, when the storage container for storing the cut bulb portion is full, the bulb portion in the container, that is, the harvested crop must be replaced with another container, and there is a problem that the harvesting operation is interrupted. The removal position of the transport conveyor with respect to the ridge planting strip was performed by operating the handle of the tractor, but fine adjustment was difficult and there was unremoved residue.
SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve such a problem of the prior art, and an object of the present invention is to provide an apparatus for harvesting rhizome crops such as garlic that can perform a smooth harvesting operation.
