Vine pruning machine with lifting cutters - has cutters on pivoting cross-member actuated by double acting rams

摘要

The vine-pruning machine has cutters which can be raised, having a chassis (1,2) on which a unit slides under the action of a ram etc. On this unit there pivots a cross-member (13) supporting the cutters, and turned by two double-acting rams (17). The unit can incorporate an intermediate chassis (5) sliding on the fixed one (1,2) under the action of a ram (8), and having two side plates with hook-type supports. The cross-member supporting the cutters pivots in the latter on two diabolo-shaped components, the double-acting rams being secured to these components and to a spindle on the intermediate chassis.
