Trip mechanism for reversible plough - has forked parallel plates with notches aligned with those in pick=up in normal position to receive cross pin

摘要

The reversible plough has an overload trip comprising a pair of froked, parallel support plates between the plough frame and a pick-up connected with a shoulder. The support plates and the pick-up have top and bottom nothces, which line up in the position of the plough and accept a top or bottom cross pin as a thrust bearing. The shoulder pick-ups are formed by a pair of forked, parallel support plates (9, 10) normal to the transverse axis (8). An energy of storage devices (12) is fitted in the intermediate space (11) bounded by the pair of support plates in front of the transverse axis.
