Reversible plough for arable field - incorporates mechanism for reliable tilting of beam using double shears lever linkage

摘要

The reversible plough has at least one beam has at least one tie rod (12) installed on the plough-beam bracket (3), extending to the rear end (13) of the beam (2) and there connected via an adjusting joint (23) with the adjusting levers (16, 17) of two opposed elbow levers (14, 15) forming a double shears (20). The tilting levers (18, 19) connected with the adjusting levers (16, 17) installed on the beam (2) have extensions (21, 22) which are connected as expanding levers with the two support points (24, 25) of the power store (6). USE/ADVANTAGE - Double shears linkage provides an adequately stiff safety device and simple transmission of the tilt movement of the plough beam.
