Description

[Detailed Description of the Invention] The present invention relates to a harvesting machine for harvesting onions and other crops, in which the harvested produce is loaded onto an agitator or the like for the harvesting machine.

Conventionally, onion harvesting machines have been used, for example, to dig up onions with a tip, shake off soil adhering to the onions while transporting the onions with a conveyor, and then shake off the soil attached to the onions while transporting the onions. The stems and leaves are separated and removed, and the onions are transported to a lifting conveyor, lifted and transported by the lifting conveyor, and transported to a transport conveyor. Some are designed to be loaded into vehicles, such as tractors.
