Description

TECHNICAL FIELD The present invention relates to a carrier that can move back and forth along ridges in which agricultural products are cultivated, for example, and that can efficiently harvest and transport agricultural products.

For example, when cultivating strawberries, they are planted on ridges formed by heaping up soil in a greenhouse. When the strawberries bear fruit and are harvested, the strawberries are harvested by hand while moving along the ridges and transported in a harvesting container or the like. At this time, the harvesting container containing a large number of strawberries is heavy and tends to be unstable when carried by hand, which is inefficient and has the problem of being difficult to move due to the narrow spacing between the ridges. On the other hand, there has been known a strawberry harvesting trolley on which a plurality of harvesting containers can be stably transported along ridges (see, for example, Patent Document 1).

In Patent Document 1, a frame with wheels that moves across strawberry ridges is provided, and the upper end of the frame is flattened to form a harvesting box placing portion. A strawberry harvesting vehicle is disclosed that moves along a path and puts picked strawberries into a harvesting box for work. Furthermore, in Patent Document 1, a harvest box mounting portion for picking is provided on both the left and right sides of the frame separately from the harvest box mounting portion, and it is proposed to improve the workability and work efficiency of strawberry harvesting. It is
