A long digging device for digging by passing the root of the long-legged root along with the soil of the cultivation ridges through the root of the long-legged root to reduce the traction load of the lifting plate and work with a small traction force. The purpose is to make it easier and easier to remove the roots of the long cucumbers raised together with the ridge soil.

[0007]

The present invention, however, has been completed based on the findings obtained through various studies and experiments for the above purpose. That is, the long roots cultivated in the cultivation ridges in the field are in a state in which, prior to harvesting, the base end portion of the stem called the crown R-2 which is continuous with the neck portion R-1 of the root portion R thereof is left. As for, the foliage is cut off and this is dug out.
Since the neck portion R-1 and the neck portion R-1 which are continuous thereto have a bad taste, the neck portion R-1 is cut off together with the crown R-2 before being dug up and shipped as a product. From this, as shown in FIG. 4, before passing through the raising plate c, the neck R-1 and the crown R-2 of the root R of the long legume R of the soil of the ridge u piled up around the long legume As shown in FIG. 5, if the soil S in the peripheral portion is removed to the side of the ridge u, the amount of soil to be lifted when passing through the lift plate c is reduced, so that the traction load is reduced.
