2. Description of the Related Art Heretofore, a root cutting device for cutting a root portion of a spherical crop while feeding and holding the foliage portion of the spherical crop while transporting the stem and leaves of the spherical crop by means of a pair of left and right screw shafts rotating inward from each other. There is also known a spherical crop preparation machine which cuts the stem and leaves with a stem cutting device (see, for example, JP-A-7-67605).

[0003]

Since the roots of spherical crops such as onions are thin and soft, many of them fall down and cling to spherical parts. Then, if you try to cut down to the root attached to the spherical part after falling down, it is easy for the root cutting device to cut into the spherical part and damage it. Conversely, if you do not cut into the spherical part, However, there is a problem that the uncut portion of the fallen root is left and the finished state is not neat, and in any case, the commercial value of the spherical portion is reduced.
