Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a harvesting machine, for example, one for harvesting agricultural products having stems and leaves, such as onions.

Conventionally, in a harvesting machine for harvesting onions, as a means for cutting stems and leaves from onions, for example, a smooth roller is provided on one side of a feed roller and rotates in opposite directions with a predetermined gap therebetween.
A cutting roller that does not contact the feed roller but contacts the smooth roller is provided at the lower part between this smooth roller and the above-mentioned feed roller, and a cutting roller that does not contact the above-mentioned feed roller but contacts the smooth roller is provided, and between this lower cutting roller and the above-mentioned upper smooth roller, onion stems and leaves are provided. There is a structure in which the onion is pulled in and the stems and leaves are cut and removed from the onion by contact rotation between the cutting roller and the smooth roller.

However, according to this structure, when the soil moisture in the field is high or the soil is clayey, it is likely that soil, onion leaves, etc. will adhere to the upper smooth roller. , the contact pressure between the upper smooth roller and the lower cutting roller may be affected, and the function of separating and removing leaves may be inhibited. Therefore, a scraper is installed on the upper smooth roller, and this scraper is used to remove the soil and leaves attached to the upper smooth roller, but this structure not only complicates the structure but also , the rotational resistance to the upper smooth roller increases,
There are problems such as the need for assembly and adjustment in a narrow space.

The present invention was developed in view of these points, and has a simple structure that allows for reliable separation and removal of harvested stems and leaves, as well as easy assembly and adjustment, and also eliminates soil adhesion without using a scraper. The purpose of the present invention is to provide a harvesting machine that can prevent entanglement of leaves, stems, and leaves.
