Description

  The present invention generally relates to dividers. More specifically, the present invention relates to a divider that can efficiently perform root cutting in an onion harvesting operation.

  In the onion harvesting operation, a root cutting operation for cutting onion roots and leaves is also performed. Onion root cutting work is usually performed using a rooting machine, but during the work, the onion leaves fall down in the wind or ripen and the leaves die, covering the path of the root cutting machine. In many cases, the leaves get tangled and the work is interrupted. In particular, after raining, the water content of the onion increases, so that it becomes easier to get involved and work loss tends to be very large.

  As a root cutting machine, there are many examples in which a root cutting operation is performed by connecting a divider with a sharp tip to a tractor.

  However, the above-mentioned conventional rooting machine has the disadvantage that the onions that have fallen into the passage are stepped on by the tractor. In addition, other root cutting machines also have a negative effect that work efficiency is poor due to tangling of leaves.
