MUSHROOM HARVESTING

摘要

MUSHROOM HARVESTING An automated mushroom harvester has a carriage 19 adapted to be moved over a mushroom-growing area, a picking head assembly being mounted on the carriage. The assembly includes a pneumatic ram 10 mounted for rotation about its own axis, the ram piston rod 14 being non-rotatable with respect to the ram cylinder 12. A suction cap 26 is mounted on the lower end of the rod 14, and control means 24 is provided for the supply of air to and from the ram 10. The control means is operated to drive the ram in such a way as to maintain substantially constant the speed of the suction cap 26 as it approaches a mushroom to be harvested, and to ensure the maximum energy of the moving parts of the picking head assembly is below 0.25 Joules, during that constant speed approach.t
