Harvester for grapes on vine - has clasping fingers carried by frame to which are attached bunches

摘要

At least one basin can be moved along the ground; with an arm stretching out above the basin and swinging continuously when commanded. Clasping placed on the basin bottom conveys from it the grape-berries which have been removed from the bunches of the vine-branches, to and through a suitable pipe. The swinging of the arm causes the fall of the grapes into the basin below it, while the grape-stalks keep on hanging on the branches since they are held by the clasping devices. Pref. the harvester has a wheel-mounted frame at whose sides there are two basins and several clasping elements which can swing above the basins. Each clasping element is held at the end of an arm and may comprise mechanical fingers whose opening and closing positions may be controlled by pneumatic double-acting cylinders.
