DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for removing roots of flowering bulbs such as tulips, and more particularly to an apparatus for removing mustache roots attached to bulbs.

[0002]

2. Description of the Related Art Conventionally, there has been a facility for sorting and drying processing in order to commercialize and ship flowering bulbs. After washing bulbs received from a producer, the bulbs are repeatedly dried and reconditioned with dehumidified air to a predetermined moisture value. Drying is performed until the roots are removed, and sorting, etc. are performed. After storage, the products are packed into cardboard ball boxes and the like and shipped.

In such equipment, a root removing machine for removing the roots of the bulbs is generally constructed as shown in FIG. 14, and is provided on one side above a bottom plate 60 which is formed in a semicircular and gutter-like shape. A rotary brush 62 is disposed on the rotary shaft 62, and the bulb S is guided to the root rolls 64, 64 while rotating the rotary brush 62. When the rotating brush 62 rotates, the roots of the bulbs S are entangled, and the bulbs S are lifted in a state where the bulbs S are hung with the roots on the upper side, and the rotating rolls 64 and 6 are rotated.
It is guided to the side 4 and the root is sandwiched between the rotating rolls 64, 64 to remove the mustache root portion.

[0004]

By the way, in such a conventional apparatus, since the rotating rolls 64, 64 are located relatively high with respect to the rotating brush 62, the bulb S is rotated by the rotating roll. In some cases, it may fall before being brought to the entangled portion of the screw 64, 64, and as a result, it may be carried to the next step without root removal.

[0005] Further, in the conventional apparatus, a bulb is mounted on a pair of rotating rolls, and the whiskers are sandwiched and removed. However, since the rotating diameter of the rotating roll is large, the rotating diameter is large. Depending on the direction of the bulb S, not only the bearded part of the bulb S, but also the top of the bulb S where the buds protrude (portion protruding tapered) may be involved, thereby damaging the bulb and reducing its commercial value. There was.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has as its object to provide a root removing device capable of reliably removing a mustache root portion without lowering its commercial value. For this purpose, the following technical measures were taken. That is, a pair of root removing belts having a predetermined width and rotating in different directions are arranged in the vertical direction, and a belt conveyor for transporting bulbs is provided adjacent to a lateral side of the root removing belt.
