Plough share for introducing fertiliser into ground - rocks laterally under control from manual lever and has blades operated by flow of fertiliser to control latter

摘要

The plough is used to introduced fertiliser into the ground at a depth for vines and fruit trees. Unbalance due to forward pitching movement is avoided by a plough which rocks laterally under manual control from a transmission system. The ploughshare (1) has two blades separated by a small distance to allow fertiliser from a hopper (5) to flow via a tube (6) and control mechanism (7) into the ground. The flow control mechanism is constructed of blades operated by flow of fertilizer and an indicator may be attached to provide indication of the flow. The ploughshare is mounted on a longitudinal axis (2) which pivots at each end of a chassis (8) to which it is attached. The rocking movement is provided by a lever (3) via a gear system (9) and operates against a counterweight (4).
