Technical Field

The utility model relates to the technical field of agricultural machinery, in particular to an onion harvesting device.

Background

Onion is generally harvested from the bottom of month 5 to the top of month 6. When the onion leaves gradually turn yellow from bottom to top, the pseudostem turns soft and starts to be inverted; the bulbs stop expanding and the outer leathery texture enters the dormancy stage, which marks that the bulbs are mature, and the bulbs are harvested in time. And drying the harvested onions in the field for 2-3 days. Directly appearing on the market, the roots can be cut off, and the pseudostem at the upper part of the bulb is cut off, and then the bulb can be put into a basket for sale. If the onion is required to be stored, the stem and leaves are not removed, and when the leaves are aired to be dry, the stem and leaves can be braided into braids and hung in a ventilated, cool and dry place, so that the onion is called as the hanging onion. In recent years, the planting scale of onions has also gradually increased. However, harvesting of onions has previously been carried out by hand.
