Abstract
A multifurrow reversible semi-mounted plough comprising a large number of plough-bodies fixed on a beam. The beam is constituted by at least two elements (12) connected two by two via an articulation (13) about an axis (16), horizontal in the working position of the plough, with structure (20, 21) for locking the articulation or articulations, the articulation (13) being preferably provided in the central portion (7) of the beam substantially in line with the wheel support group (8-10) of this central portion. The invention allows having a ploughing depth of the ploughshares almost equal on all the ploughshares in spite of the large width of the plough.
Claims4
A multifurrow reversible semi-mounted plough comprising a large number of plough-bodies fixed on a beam, the beam being constituted by at least two elements interconnected via an articulation about an axis which is horizontal in a working position of the plough, and means for selectively locking and unlocking said articulation, said means for selectively locking and unlocking said articulation comprising a mobile pin member carried by one of the articulated beam elements, engaging in a generally V-shaped notch formed in the other beam element, and means for remotely selectively moving said pin member into and out of said notch.
A multifurrow reversible semi-mounted plough comprising a large number of plough-bodies fixed on a beam, the beam being constituted by at least two elements interconnected via an articulation about an axis which is horizontal in a working position of the plough, means for selectively remotely locking and unlocking said articulation, said means for selectively locking and unlocking said articulation comprising a mobile pin member carried by one of the articulated beam elements, engaging in a generally V-shaped notch formed in the other beam element, means for remotely selectively moving said pin member into and out of said notch and a double-acting jack connected between flanges extending from each of said two elements for selectively changing the angle between said two elements in the unlocked state of the articulation.
A multifurrow reversible semi-mounted plough comprising a large number of plough-bodies fixed on a beam, the beam being constituted by at least two elements interconnected via an articulation about an axis which is horizontal in a working position of the plough, means for remotely selectively locking and unlocking said articulation, another lockable articulation between said elements about a vertical axis, and a double-acting jack connected between one of said elements and a stationary point on the plough for selectively changing the angle between said elements about said vertical axis.
