摘要

PROBLEM TO BE SOLVED: To accommodate an onion collected from a field in a cargo basket or a bag placed on a loading platform of a transportation work vehicle, and when the load 1 becomes about 300 kg or 200 kg, a worker's human power is provided by a simple structure. Make it easy and safe to unload. SOLUTION: The tilt angle θ from the horizontal of the loading platform is stopped at a stable static angle −θ1 in the horizontal direction from a sliding angle −θ0 where the load starts to slide on the loading platform −θ0, and a pusher device with respects the load. By applying a pulling force of about 15 kg, the load is slowly slid on the loading platform to touch the ground / floor where the load is to be unloaded, and then the vehicle body is advanced to unload the load 1 onto the field.
