Description

Root crops harvesting apparatus

The present invention relates to a root crop harvesting device, and more particularly, to a root crop harvesting device capable of easily harvesting underground garlic.

Recently, agricultural technology has been improved to sow the seeds of crops with a sowing machine and harvest the cultivated crops with a harvester.

In order to harvest various root crops, such as sweet potatoes, potatoes, garlic, ginseng, deodeok, bellflower, and onions, which are generally grown underground, many workers directly excavate them using agricultural tools such as hoes and shovels, or harvest a large amount of crops. The crop is harvested using a crop harvesting device.

The crop harvesting device as described above may be divided into a self-propelled harvester that harvests while driving by its own power and a tow-type harvester that harvests while driving along the field by connecting and towing a tractor or a tiller.

The crop harvesting device digs out crops grown in the ground while driving along the ridges on both sides of the ridge where the crops are grown.

In particular, a harvesting device for harvesting a root crop such as garlic should be able to harvest a crop in the ground and shake the soil of the excavated crop.

A general root crop harvesting device has been developed to have a digging function, but most of them do not have a function for mowing the soil. Therefore, dust removal requires the use of a separate facility or manual labor of a worker.

As such, the general root crop harvesting apparatus is uneconomical because it is required to additionally use expensive equipment for mowing after excavation or manual work of a worker for mowing is required.
