2. Description of the Related Art Conventionally, when a crop such as vegetables or fruits is stored in a tray and packed in a pack, an operator conventionally handles the crop which is packed in a pass-through box such as a cardboard box or a container case and carried to a sorting factory. They are taken out one by one, or transferred into a tray via a transfer means such as a belt conveyor, and conveyed to the next packaging step. For this reason, when handling a large amount of agricultural products, it took a lot of time and work efficiency was poor.

[0003] In recent years, there has been proposed an apparatus for cleaning agricultural products by spraying water onto the agricultural products while arranging and transporting the agricultural products using a flow of water. This device aligns and transports crops by the flow of water, and at the same time, sprays water from upper nozzles toward the crops floating on the water surface, thereby washing and removing pesticides and the like remaining on the surface of the crops. You can do it.

However, in the above-described apparatus, since water is sprayed from the upper nozzle onto the crop, it is not sufficient when handling crops floating on the water surface such as eggplants and cucumbers. Although it can be washed, there is a possibility that it may not be sufficiently washed when handling agricultural products that sink into water, such as tomatoes and persimmons. For this reason, when handling crops that sink into the water, workers must remove them one by one and perform cleaning and removal operations such as wiping before transferring them to the next process. Could not be planned.

[0005] Further, in the above-mentioned apparatus, when the agricultural products are transferred to the next process, the workers and the conveyor come into direct contact with the agricultural products, so that the agricultural products are easily damaged, and the quality or the like is liable to cause a problem. .

[0006] From the above, the present invention is capable of cleaning and arranging crops submerged in water sufficiently and transporting the crops in a sufficient manner, as well as suppressing damage when the crops are transferred to the next process. An object is to provide an alignment conveyance device.
