<p>The picking lug is fixed to the chain of a farm machine harvesting maize, having two parallel and roughly triangular walls whose bases are equal to the length of a chain link. The walls (2) form, with a connector (5) between their apices, an open passage, and they can each form an equilateral triangle. Each can comprises three plates of the same length, joined together at the ends, one being a side plate of an external chain link. One can have an oblique bent central portion, its two ends extending in parallel planes spaced the thickness of the plate.</p> |
