Description
La présente invention a pour objet un dispositif de construction simple et économique, destiné à être installé sur tous tracteurs à relevage hydraulique à trois points, qui permet le retournement automatique de tous types de charrues réversibles à un, deux ou trois socs.
Suivant l'invention, un bras incliné A fixé rigidement d'une manière amovible à l'arrière du tracteur, commande l'abaissement du levier B, lors du déplacement angulaire des bras du relevage hydraulique, par l'intermédiaire d'un bras C relié au bras A.
Le levier B actionne dans ses déplacements angulaires le levier D dans laquelle est engagée un ressort qui est relié à un point fixe de l'axe central.
Le ressort s'étend jusqu'au moment où l'extrémité du levier de commande F, retire le verrou E de son encoche. De ce fait, l'axe central est libéré et sollicité que par la traction du ressort, doit pivoter dans la botte à roulements à billes, solidaire de la tête.
Un dispositif G étant prévu entre la tête et l'axe central pour régler la position angulaire de l'axe par rapport à la dite tête de charrue en vue de donner aux pièces travaillantes fixées à l'axe, l'inclinaison voulue suivant la déclivité du terrain à labourer.
La largeur de labour peut être réglée par le déplacement de l'age de la charrue par rapport à l'axe central de la tête.
Le démontage du dispositif de retournement automatique peut s'opérer très facilement par simple dévissage du pivot H.
L'invention n'est pas limitée à la forme de réalisation décrite et figurée au dessin et de nombreuses modifications constructives pourront y être apportées sans s'écarter de l'esprit de l'invention.
Pour la compréhension voir le plan ci-joint
The present invention relates to a device of simple and economical construction, intended to be installed on all tractors with hydraulic three-point lift, which allows the automatic turning of all types of reversible plows with one, two or three coulters.
According to the invention, an inclined arm A fixed rigidly in a removable manner to the rear of the tractor, controls the lowering of the lever B, during the angular displacement of the arms of the hydraulic lift, by means of an arm C connected to arm A.
The lever B actuates in its angular movements the lever D in which is engaged a spring which is connected to a fixed point of the central axis.
The spring extends until the end of the control lever F removes the latch E from its notch. As a result, the central axis is released and requested only by the traction of the spring, must pivot in the ball bearing boot, integral with the head.
A device G being provided between the head and the central axis to adjust the angular position of the axis with respect to said plow head in order to give the working parts fixed to the axis, the desired inclination along the gradient of the land to be plowed.
The plowing width can be adjusted by moving the plow age relative to the central axis of the head.
The automatic turning device can be removed very easily by simply unscrewing the pivot H.
The invention is not limited to the embodiment described and shown in the drawing and numerous constructive modifications can be made to it without departing from the spirit of the invention.
