Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deep root vegetable harvester for digging vegetables such as burdock.

[0002]

Heretofore, when vegetables are pulled upward by a pair of pulling belts pulled by a tractor and harvested, deep-rooted vegetables such as burdock are more likely to be soiled than by pulling the foliage. It is desirable to pull out by holding the lower part of the root in the middle, less damage to vegetables,
Although the commercial value can be prevented from lowering, there is a problem in the drawing function such that the root of the vegetable cannot be easily held by the end of the drawing belt.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a deep root vegetable harvester comprising a pair of pulling belts for holding and pulling vegetables, and for continuously lifting vegetables in the field to the ground.
On the tip side of the pull-out belt, a soil removing body for rotating in the opposite direction to the rotation of the pull-out belt is provided, and since the soil at the root of the vegetables is removed by the soil removing body, the tip side of the pull-out belt is moved. , The lower side of the vegetable root can be easily clamped by the pull-out belt, and the pulling force can easily prevent the vegetable root from cutting and reducing the product value, improving the function of extracting deep root vegetables Can be easily achieved, and the harvesting structure can be simplified and the harvesting operation speed can be easily increased as compared with a structure in which soil around the roots of vegetables is scooped and excavated.

[0004] Further, the clamping interval between the feed end portions of the pair of pull-out belts is adjustable so that the timing of releasing vegetables from the pull-out belt can be easily changed, and the workability of harvesting vegetables can be easily improved. It is possible.
