Conventionally, as described in Japanese Utility Model Publication No. 59-15863, a foliage processing device for a harvester for harvesting onions has been constructed using a smooth roller that rotates in contact with each other in opposite directions and a protrusion in the axial direction. A structure is adopted in which a plurality of roller units each including a tapping roller formed in a spiral shape are arranged side by side and mounted on shafts.

When the onion with stems and leaves is carried onto the stem and foliage processing device, the onion is conveyed by each set of smooth rollers and tapping rollers in a plurality of roller units, and the onion leaves are transferred between the smooth rollers and the tapping rollers. It is designed to be separated and removed from its base while being held between the rollers.

[Problem that the invention attempts to solve]

In the case of the above structure, the onion with stems and leaves is separated and removed from the onion by being torn from the base between the smooth roller and the tapping roller, so the onion leaves do not become depleted and turn green. If this condition occurs, the onion may be damaged, and the shoulder portion of the onion may turn black due to friction between the smooth roller and the tapping roller, and the onion root may become damaged between the smooth roller and the tapping roller. If the leaves are placed above the smooth roller and the tapping roller, the leaves may not be drawn in between the smooth roller and the tapping roller. There is a problem in that the cutting position of the stems and leaves is not constant depending on the condition of the stems and leaves.

Therefore, this invention was made in view of the above points,
It is an object of the present invention to provide a foliage processing device for an onion harvester that transports onions while suspending them, cuts the foliage at a desired position during the transportation, and allows the cutting position to be arbitrarily selected and set. It is something.

[Means for solving problems]

A belt is provided, and a pair of guides are provided along the lower part of the inner parts of the pair of clamping and conveying belts that rotate close to each other to guide the onion leaves being clamped and conveyed between the inner parts. A pair of adjustment arms are arranged opposite to each other at the bottom, and one end of the pair of adjustment arms is attached close to one end of each guide so as to be rotatable in the vertical direction, and the other end is attached to each guide. The inner side of the pair of clamping and conveying belts is attached to the other end of the guide so as to be vertically adjustable and guides the conveyance of the onions while setting the cutting position of the stems and leaves. A cutter is installed to cut the leaves and stems that are held between them.

[Effect]

The stem and leaf processing device of the onion harvesting machine of the present invention is configured as described above, so that each pair of adjustment arms is vertically adjusted with respect to a pair of guides, and the other end of the pair of adjustment arms is adjusted at the set position. It is attached and fixed to the other end of each pair of guides. This sets the cutting length of the onion stems and leaves.

Then, when the onion leaves are clamped between the inner parts of the pair of clamping and conveying belts and conveyed between the pair of guides and the pair of adjustment arms, the stems and leaves are cut from the set position by the cutter during the conveyance.

[Effect of idea]

According to the present invention, onion stems and leaves are conveyed while being held between the rotating inner parts of a pair of clamping and conveying belts, so that onions are carried while being suspended, and the onion's own weight makes it easy to cut the stems and leaves. Therefore, the cutter provided during transportation can reliably cut the stems and leaves from the set position. Furthermore, by moving the onion leaves between the pair of guides and between the pair of adjustment arms, the onion leaves can be reliably guided to the cutter, and the cutter can accurately cut the onion leaves. Furthermore, since a pair of adjustment arms are provided for each of the pair of guides so that the position can be adjusted in the vertical direction, the cutting length of the stems and leaves can be arbitrarily selected and set depending on the harvesting situation of the onion, such as depending on the condition of the stems and leaves. Moreover, one end of the pair of adjustment arms on the carry-in side is rotatably attached, and the other end in the carry-out direction is attached so that the position can be adjusted in the vertical direction, so onions can be transported along the pair of adjustment arms. By doing so, the cutting length of the stems and leaves automatically becomes the preset cutting length, and each stem and leaf can be uniformly cut to the set length. Therefore, it does not damage the onion, discolor the onion, or cause cutting errors when cutting the stems and leaves, unlike those that tear the stems and leaves between rollers.
