Description

AGRICULTURAL HARVESTER

The present invention relates to a crop harvester designed to harvest relatively long weeds or crops such as rice and barley.

The traditional basketball harvesting long grass, rice, and barley has been used for sickles and pickles. In this case, the worker uses the sickle to cut the grass directly, then bundles it into a bundle and performs the next step.

As the need for the development of agricultural machinery technology and the reduction of labor force increased, a harvester designed to enable automatic harvesting using power was developed. Harvesters such as long grains, rice, and barley can be divided into two types: cutting (cutting grass), cutting (binding), and cutting (harvesting) grains. These specialized harvesters are often fitted with mechanical form or working mechanism depending on the characteristics of the target crops and workpieces.

When the contents of the work or objects are varied, the dedicated harvester can not be used at all times, so it is often convenient or cost effective to expand the use of one equipment. Korean Unexamined Patent Publication No. 2011-0087755 or Korean Unexamined Patent Publication No. 1031516, which is designed by the applicant, shows examples in which a rotary cutter surrounded by a cover is used for harvesting as well as weeding.

On the other hand, even if the combine harvester is used as a special harvester, the rice located at the edge of the cultivated land is difficult to use because of the combine, so it may be cut directly using sickles.
