Description

[Detailed Description of the Invention] Technical Field of the Invention The present invention relates to a foliage processing device, for example, a device for separating and removing the foliage of a harvested product such as onion in a harvester.

Technical background of the invention and its problems Conventionally, when harvesting onions, onions with stems and leaves are dug up, and the onions are transported onto a conveyor while sieving off the soil. Some devices have a structure in which the onions are carried into the onion, and the onions are transferred to the rear while removing the leaves from the onions in this foliage processing device.

The above-mentioned foliage processing device includes a cutting roller having a spiral protrusion around the periphery and a smooth roller disposed opposite to this cutting row 2, and rotation of the cutting roller and the smooth roller.
If the onion is transported and the onion leaves are drawn between a cutting roller and a smooth roller to be pinched and removed, the soil may be damp or contain a lot of moisture without dying. In such cases, there is a strong tendency for the rollers to knead the onion stems and leaves together with the soil and cause them to become tangled.In such cases, the ability to cut the onion stems and leaves is significantly reduced, and the friction between the rollers and the onions increases. There is a problem that the onion's transportability is impaired and the onion's outer skin may be peeled off or damaged.

Therefore, it is possible to provide a scraping body on the roller, but even with this method, if there is a spiral protrusion around the circumference, such as a cutting roller, the scraping body can function sufficiently due to the protrusion. However, there is a drawback that it is extremely difficult to remove leaves, leaves, etc. that have wrapped around and attached to the surface of the cutting roller that is lower than the protrusion.

Purpose of the invention The present invention fully functions a plurality of removal pieces on a cutting roller having a spiral protrusion around its periphery to prevent stems and leaves from adhering to the cutting roller. The purpose of this invention is to prevent a decrease in the ability to cut stems and leaves due to cutting, to ensure the removal of stems and leaves, and to enable smooth transportation of harvested products such as onions without damaging them.

Summary of the invention The present invention has multiple sets of roller units each consisting of three rollers arranged in parallel in the horizontal direction. A smooth feed roller that rotates in opposite directions with a predetermined gap is provided on one side, and a cutting roller that does not contact the smooth feed roller is provided at the bottom between the smooth feed roller and the cutting roller. A plurality of removal pieces made of a flexible member are rotated in the length direction of the cutting roller of each set of roller units, and a plurality of removal pieces made of a flexible member are rotated in contact with the cutting roller of each set of roller units. This is a characteristic feature.

Moreover, since each of the removal pieces 59 is flexible, it does not impart a large rotational resistance to the cutting roller 35, thereby preventing soil from adhering to the cutting roller 35 and preventing the stems and leaves of the onion a from becoming entangled.

Effects of the invention According to the invention, a plurality of sets of roller units, each set of three rollers, are arranged horizontally in parallel, and each set of roller units has a spiral protrusion on the periphery. A smooth feed roller is provided on one side of the cutting roller and rotates in opposite directions with a predetermined gap therebetween, and a lower portion between the smooth feed roller and the above-mentioned cutting roller is provided so as not to contact the smooth feed roller. A smooth roller is provided that rotates in contact only with the cutting roller, and a plurality of removal pieces made of flexible members are rotated in the longitudinal direction of the cutting roller of each set of roller units. Therefore, each of the removal pieces acts sufficiently on the surface of the cutting roller while slidingly contacting the surface along with the rotation of the cutting roller having spiral protrusions and stripes as it rotates. It is possible to reliably prevent stems, leaves, dirt, etc. from adhering to the cutting roller.
It prevents the cutting ability of stems and leaves from being reduced due to stems and leaves adhering to the cutting roller, and it is possible to always and reliably remove stems and leaves without damaging harvested products such as onions.
This can be transferred smoothly using the old smooth rollers.
Since it only contacts the cutting roller and does not contact the smooth feed roller that is separated from the cutting roller, there is less risk of soil adhering to the smooth feed roller or stems and leaves wrapping around it, and the smooth roller rotates in the opposite direction to the cutting roller. Also, soil and foliage adhering to the cutting roller can be reliably removed, and the cutting roller can always reliably transport the harvest and separate and remove the foliage.
