Abstract

The present invention relates to a tractor trailed type Welsh onion harvester which is trailed by a tractor to be moved and connect a universal joint to PTO of the tractor for a hydraulic pump to be operated. Welsh onion planted in a ridge between fields is individually dug by transmitting pressure oil generated in the hydraulic pump to a hydraulic motor of a chain conveyor unit (400) simultaneously supporting and transferring roots of the dug Welsh onion and soil, a transfer conveyor unit (600) gripping stems of the dug Welsh onion to be transferred to the rear, and a soil brushing unit (500) installed in the rear of the chain conveyor unit. Therefore, Welsh onion harvesting work which has mostly depended on manual labor can be mechanized and automated. More specifically, after Welsh onion of which soil has been brushed is horizontally transferred by passing through a horizontal transfer unit (700), a constant weight of the Welsh onion is measured in a measuring fall unit (800) to automatically fall to the ground. Therefore, a worker couples a bunch of the Welsh onion to be collected and complete harvesting work.
