Abstract

The motorisation of agriculture has lead users to employ centrifugal fertiliser spreaders and has required of the latter a distribution of the fertiliser corresponding to the user's request; the fertiliser must therefore be spread, either to the right, or uniformly, or to the left of the implement; in order to achieve this it is necessary to vary the angle of the vanes, hence the need to stop the implement, the vanes being fixed by two bolts to the disc. In order to avoid any waste of time, the vanes are mounted on the disc with the aid of a spindle and they are oriented by the vane arm bearing on a cam which can move about a [lacuna] causing this cam to rotate, and by stopping it in a predetermined position, the desired orientation of the vane and the required distribution of the fertiliser is obtained. The present invention allows the vanes and the desired distribution to be adjusted without stopping.

Description

DESCRIPTION
tes caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre d'un mode de réalisation selon l'invention donnée à titre d'exemple en référence aux dessins annexés dans lesquels la figure I est en vue du plateau de distribution muni de ces aubes et montrant la came d'orientation des aubes ta figure II est une vue du plateau montrant la position des aubes et son levier d'appui sur la came.DESCRIPTION
Your characteristics and advantages of the invention will also emerge from the description which follows of an embodiment according to the invention given by way of example with reference to the accompanying drawings in which FIG. I is in view of the tray. distribution fitted with these blades and showing the blade orientation cam ta FIG. II is a view of the plate showing the position of the blades and its support lever on the cam.

Ainsi qu'on le voit les aubes sont montees sur un axe vertical (I) et tournent sur cet axe. Un bras (2) fixe à lgaube en (3). A son extrémité un galet (5) en contact avec la came (6). L'appareil étant en marche la force centrifuge maintient le galet au contact de la came et assure un angle déterminé à 19aube, il suffit d'effectuer une rotation de la came autour de son axe à l'aide d' un levier (7) et ainsi varier la répartition de l'engrais. As can be seen, the blades are mounted on a vertical axis (I) and rotate on this axis. An arm (2) fixed to the long at (3). At its end a roller (5) in contact with the cam (6). The apparatus being in operation the centrifugal force maintains the roller in contact with the cam and ensures a determined angle at 19aube, it is enough to carry out a rotation of the cam around its axis using a lever (7) and thus vary the distribution of the fertilizer.

Pour assurer le contact parfait du galet sur la came un ressort amortisseur (rb) amorti et supprime les vibrations qui pourraient se produire. Bien entendu ce mode de réalisation n'est donne qu'à titre d'exemple, c'est ainsi que le ressort (8) travaillant à la traction peut-être remplace par un ressort travaillant à la compression, être en métal ou matière quelconque, la position de ces ressorts peut-être à un endroit approprié, que la came peut avoir une forme quelconque, être interchangeable, que la came peut-être remplacee par un vilbrequin et les galets remplacés par des coussinets fixés, sur ce vilbrequin sans sortir du cadre de l'invention. To ensure perfect contact of the roller on the cam a damping spring (rb) damped and suppresses the vibrations which could occur. Of course this embodiment is given only by way of example, this is how the spring (8) working in tension can be replaced by a spring working in compression, being made of metal or any material , the position of these springs may be at an appropriate location, that the cam may have any shape, be interchangeable, that the cam may be replaced by a crankshaft and the rollers replaced by bearings fixed on this crankshaft without leaving of the scope of the invention.

Claims

I / Centrifugal fertilizer distributor with projection vanes

erientables in nerves.

II / Characterized by the fact that this orientation depends on a cam on which the blade lever comes to bear.

III / Characterized according to claim (I) that a lever makes it possible to vary the position of the come.

IV / Characterized according to claim (II) in that the lever provided with a roller follows the shape of the cam.

V / Characterized according to claim (III) that the lever has its support provided by centrifugal force.

VI / Characterized according to claim (V) by the addition of a tension or compression spring absorbing the vibration that the blade could have during the operation of the apparatus,

VII / Characterized according to claim (VI) by the possibility of loading the cam for a cam of suitable shape for the work required.
