This machine uses a reciprocating cutter to cut the roots of bok choy, and the cut crops are transported to a collection basket by the conveyor. The machine is electric, has a small body and can rotate in a small radius, which is suitable for harvesting operations in small greenhouses. Replacing manual harvesting with automated machinery can not only reduce the hard work and reduce the manpower demand for leafy vegetable harvesting; through the rapid harvesting of machinery, the quality of leafy vegetables can also be improved simultaneously.
