Description

  The present invention relates to, for example, an onion rhizome cutting device that cuts roots and stems from an onion sphere to make only an onion sphere, and is particularly safe and semi-automatically independent of the size and shape of the onion. The present invention relates to a device for providing a rhizome cutting device having an automatic cutting function capable of reliably cutting.

  Conventionally, a onion rhizome cutting device that cuts roots and stems from an onion to make only an onion sphere includes, for example, a fully automatic cutting device provided with an onion transport tool, a gripping tool, a cutting tool, a discharge chute, etc. (Onion adjuster) is provided.

  Hereinafter, a configuration of a conventional onion rhizome cutting device will be described. In the cutting device (onion adjusting machine), a conveying unit that conveys the onion in the horizontal direction is configured by a front alignment conveying device and a rear holding conveyance device, and the root of the onion is cut above the clamping conveyance device. The root cutting device is arranged below the stem cutting device for cutting the onion stem, and the aligning and conveying device is mounted on two parallel rotation shafts with a spiral brush and rotated in opposite directions. And a reversing mechanism is arranged above the midway part of the aligning and conveying apparatus (see, for example, Patent Document 1).

In the above cutting device (onion adjuster), a transport unit for transporting onion, a sandwiching transport device, a root cutting device for cutting onion root above the sandwiching transport device, and a stem for cutting onion stem below The cutting device and the aligning / conveying device are mounted on two parallel rotating shafts in a spiral manner, rotated in opposite directions and transported, and a reversing mechanism is arranged above the middle of the aligning / conveying device. Therefore, there is an advantage that the cutting efficiency of onion roots and stems is performed fully automatically and the work efficiency is improved.
However, full automation of the cutting device (onion adjuster) leads to complicated and expensive equipment and complicated maintenance, and reduces profitability for onion production. In the first place, onion production is seasonal and not always used throughout the year, so it is suitable for large-scale onion cultivation, but not suitable for producers of small to medium-sized onion cultivation. In other words, mechanization involves a large amount of capital input, machine maintenance and depreciation, and there is a problem that it is difficult for small-scale producers to secure profits from onion production.
