However, in such a method of transporting heavy vegetables, harvested vegetables are loaded on a unicycle, transported to a truck outside the field, and transshipped from the unicycle to a truck bed. After transporting to the collection site, a series of operations such as unloading heavy vegetables from the truck bed at the collection site are performed, which is not only complicated but also requires long-term transshipment of heavy vegetables. It takes place over time, forcing hard work.

[0004] In addition, since the transfer work of heavy vegetables is performed for heavy vegetables for each single item, not only the work efficiency is reduced, but there is a great risk of damaging the vegetables. .

[0005] In view of the above, not only can the work efficiency be improved by packing the harvested heavy-weight vegetables into containers and performing a series of transporting operations to the collection point for each container unit. It is thought that the container packed with heavy vegetables has a considerable weight, so when carrying out container reloading work manually, it is not only a great deal of fatigue. However, there is a problem that a cause of back pain is caused.

[0006] Therefore, it is desired to mechanize the reloading operation of containers packed with heavy vegetables.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and aims to prevent damage to heavy vegetables and to improve the efficiency of reloading containers with heavy vegetables.
