摘要： There is disclosed a combination of a semi-mounted reversible plough (10) and a seed preparation device (11) which are towed behind a tractor in order to carry out a ploughing action and a seed preparation action during a single pass over the ground, in which the plough has a short leading towing beam (12) provided with a forward hitch (13) for coupling the plough to the rear of the tractor; a long towing beam (15) coupled with beam (12) and forming a rearward prolongation thereof; a carrying beam (20) coupled with long towing beam (15) and carrying pairs of reversible plough bodies (23) alont its length; a cylinder operated crank mechanism (17, 18) operable to rotate towing beam (15) and carrying beam (20) as a unit about the longitudinal axis (19) of beam (15) in order to reverse the position of the plough bodies; a coupling beam (24) mounted at its forward end via a mounting beam (43) on the carrying frame (20) and towing beam (15) and projecting laterally therefrom; a swivel connector (25) at the trailing end of coupling beam (24) which is attached to the leading end of a draw bar (41) of the device (11); and a cylinder operated parallelogram linkage (24, 29) which can be operated in order to initiate relative lateral displacement to take place between plough (10) and device (11) during forward movement of the combination, followed by pivoting of the carrying beam (20) and towing beam (15) about the longitudinal axis (19) during reversal of the plough bodies (23) which is permitted by the swivel connector (25), and which takes place during movement of the combination over the headland prior to a return pass over the field to be ploughed and prepared. Preferably, a seed unit (34) is coupled with the seed preparation device, so that ploughing, soil preparation and seeding can take place during a single passage across a field, and the entire combination can automatically adjust itself during reversal of the plough bodies and turning of the combination in the headland.

摘要： L'invention concerne une charrue réversible semi-portée (10) et un dispositif de préparation de semences (11) combinés, à atteler derrière un tracteur de manière à effectuer une opération de labourage et une opération de préparation des semences en une seule passe sur le champs. La charrue de cette combinaison comprend un arbre avant d'attelage court (12) pourvu d'un crochet d'attelage avant (13) qui sert à coupler la charrue à l'arrière du tracteur. Elle comprend également un arbre d'attelage long (15) couplé à l'arbre (12), dans son prolongement, ainsi qu'un age (20) couplé à l'arbre d'attelage long (15) et pourvu de paires de corps de charrue réversibles (23) sur toute sa longueur, un mécanisme à manivelle (17, 18) qui permet de faire tourner l'arbre d'attelage (15) et l'age (20) comme une unité autour de l'axe longitudinal (19) de l'arbre long (15) afin d'inverser la position des corps de la charrue, un arbre d'accouplement (24) dont l'extrémité avant est montée via un arbre d'assemblage (43) sur l'age (20) et sur l'arbre d'attelage (15) et qui s'étend latéralement à partir de lui. De plus, elle est équipée d'une barre à rotule (25) située à l'extrémité de queue de l'arbre d'accouplement (24) qui est monté à l'extrémité de tête d'un crochet de traction (41) du dispositif (11). Elle comporte également une liaison en parallélogramme actionnée par un vérin (24, 29), qui peut être actionnée pour amorcer un déplacement relatif latéral entre la charrue (10) et ledit dispositif (11) pendant le déplacement en avant de la combinaison, suivi du pivotement de l'age (20) et de l'arbre d'attelage (15) autour de l'axe longitudinal (19) lors du renversement des corps de la charrue (23) grâce à la barre à rotule (25). Cette opération s'effectue pendant que ladite combinaison se déplace avant la passe en retour dans le champ à labourer et à préparer. L'unité d'ensemencement (34) est de préférence couplée au dispositif de préparation de semences, pour que le labourage, la préparation du sol et l'ensemencement s'effectuent en

摘要： An overload protection mechanism for a plough beam (3). The plough beam (3) carrying a plough body (6) is retained in ploughing position by means of a flexible, power-exerting device comprising a fluid pressure operated piston cylinder (11, 11', 12, 12'), the piston rod (12) thereof being coupled to the front end of a strut (10) anchored (9) at the rear end of the plough beam (3). However, plough beam (3) carrying plough body (6) may leave the ploughing position when the plough body (6) hits an obstacle (8) positioned in the soil and capable of being passed by the plough body (6) through a rotation of the plough beam (3) at the front end thereof, cooperating with the plough beam carrier (4) through a hinge device (16, 16'), the plough beam (3) thereafter being brought to retake the position corresponding to the ploughing position of the plough body (6). In order to achieve a protected positioning of the piston cylinder (11, 11', 12, 12') and, simultaneously, secure that the strut (10) at all times will be subjected to a tensile strain as plain as possible and minimum bending load, the piston cylinder (11, 11', 12, 12') is mounted in the plough beam carrier (4) by means of a universal joint (13, 14, 15).

摘要： There is disclosed a semi-mountable plough comprising an elongate plough frame having a long forward frame section (1) carrying a plurality of plough bodies (2), a short intermediate section (3) pivotally connected to the rear end of the forward section (1), and a rear frame section (5) pivotally connected at its forward end to the rear of the intermediate section (3), with the plough being of a reversible type and the sections (1, 3 and 5) being pivotable relative to each other in a generally horizontal plane to take up new positions suitable for movement of the plough in a reverse direction. The rear frame section (5) is pivotable about a horizontal pivot (11) so as to follow any unevennesses in the ground, and an hydraulically operated actuator (18, 19, 12') is coupled with said rear frame section and is operative to urge the frame section to pivot downwardly about said horizontal pivot (11) and thereby maintain the plough bodies (21) carried by the rear frame section (5) at a required ploughing depth, and in that a hydraulic control circuit is connected to said actuator and includes a pressure regulator (20) to control the hydraulic pressure supplied to the actuator (12, 19, 12') so that a controlled biasing force is applied to the rear frame section (5) which maintains the required ploughing depth of the plough bodies (21), but which can be overcome so as to allow pivoting movement of the rear frame section (5) in order to follow the contour of the ground which is being ploughed.
