Harvester for underground crops

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a subterranean crop harvester, and more particularly to a subterranean crop harvester which is capable of continuously harvesting subterranean crops such as potatoes, sweet potatoes, onions, garlic, carrots, will be.

In general, there are potatoes, sweet potatoes, onions, garlic, and carrots, which are grown in the soil. When harvesting these underground crops, the worker has to harvest every time he digs the ground and consumes time and money. Cursor Recently, a bulb harvesting device has been developed, which is a type of agricultural machinery connected to the rear of agricultural tractors such as tractors.

Such conventional bulb harvesting devices have a configuration in which a wing shovel is inserted into a ground by merely pulling a wing-shaped wing shovel into a ground by simply pulling the wing-shaped shovel. When foreign substances such as vinyl, wood chips, or stones exist in the ground, There was a problem that the foreign substances stick to each other and interfere with the insertion of the wing shovel into the ground.

In addition, the conventional bulb harvesting apparatuses can not control the depth of the wing shovel inserted into the ground according to the environment of the cultivated land or the characteristics of crops, so that when the wing shovel is inserted thinly, the crop is easily damaged and the wing shovel is inserted too deeply There is a problem such that a greater amount of force is consumed than necessary.

In addition, the conventional bulb harvesting apparatuses have problems in that the pulling force of the towing vehicle is always constant, and the frictional force acting on the blade shovel inserted into the ground is large, so that the pulling speed is slowed and the harvesting time is long.
