Abstract

The fertilizer spreader has disks (herissons) which are driven by the tractor engine. Their speed of rotation can be adjusted without changing the tractor speed using a gearbox with two input shafts (3, 4), each of which can independently be connected to the engine by a cardan joint (2). It also has two output shafts (7, 8) which can be connected independently to the disks by a second cardan joint (5).

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne un dispositif installé sur un épandeur de fumier permettant à partir'd'une vitesse d'entraînement unique par la prise de force du tracteur d'obtenir plusieurs vitesses de rotation des hérissons.  The present invention relates to a device installed on a manure spreader allowing from a single drive speed by the PTO of the tractor to obtain several rotational speeds of hedgehogs.

La variation de la vitesse de rotation des hérissons permet de faire varier la largeur d'épandage de fumier, le degré d'émiettement du fumier épandu, et la puissance absorbée par l'épandeur.  The variation of the speed of rotation of the hedgehogs makes it possible to vary the width of spreading of manure, the degree of crumbling of the spread manure, and the power absorbed by the spreader.

Un tel dispositif permet à l'utilisateur de l'épandeur d'adapter la vitesse de rotation des hérissons à la nature du fumier à épandre, du terrain sur lequel il épand, et à la puissance du tracteur.  Such a device allows the user of the spreader to adapt the speed of rotation of the hedgehogs to the nature of the manure to be spread, the terrain on which it spreads, and the power of the tractor.

Les épandeurs de fumier traditionnellement utilisés sont entraînés par la prise de force des tracteurs auxquels ils sont attelés. Les 2 vitesses de rotation normalisées des prises de force étant de 540 trs/mn et 1000 trs/mn. Les hérissons de l'épandeur sont entraînés par une transmission mécanique. Le rapport entre la vitesse de rotation des hérissons et la vitesse de rotation de l'arbre entraîné par la prise de force du tracteur est constant, et défini par construction. La vitesse de rotation des hérissons est unique et déterminée par construction.  Manure spreaders traditionally used are driven by the PTO of the tractors to which they are coupled. The 2 standard rotational speeds of the PTOs are 540 rpm and 1000 rpm. The spreader's hedgehogs are driven by mechanical transmission. The relationship between the speed of rotation of hedgehogs and the speed of rotation of the shaft driven by the PTO of the tractor is constant, and defined by construction. The speed of rotation of hedgehogs is unique and determined by construction.

Le dispositif selon l'invention permet pour une même vitesse de rotation de la prise de force du tracteur d'obtenir plusieurs vitesses de rotation des hérissons.  The device according to the invention allows for the same speed of rotation of the PTO of the tractor to obtain several speeds of rotation of the hedgehogs.

Selon une forme de réalisation préférentielle, le dispositif selon l'invention est constitué par un boîtier réducteur à engrenages parallèles (1) de rapport 1.4/1. La transmission par joint de cardan (2) reliant le tracteur à l'épandeur peut être branchée sur l'un ou l'autre des arbres d'entrée (3) et (4). De la même façon la transmission par joint de cardan (5) entraînant le (s) hérisson (s) peut être branchée sur l'un ou l'autre des arbres de sortie (7) et (8). According to a preferred embodiment, the device according to the invention consists of a reduction gearbox with parallel gears (1) of ratio 1.4 / 1. The universal joint transmission (2) connecting the tractor to the spreader can be connected to either of the input shafts (3) and (4). In the same way the transmission by universal joint (5) driving the hedgehog (s) can be connected to one or the other of the output shafts (7) and (8).

4 combinaisons possibles : - la combinaison (3)- (8) donnant un rapport 1. 4/1 - les combinaisons (3) - (7) et (4)- (8) donnant un rapport 1/1 - les combinaisons (4)- (7) donnant un rapport 1/1.4
Selon d'autres formes de réalisation, le dispositif peut être constitué par une boîte de vitesses à plusieurs rapports, par un variateur de vitesse mécanique, électrique, ou hydraulique.
4 possible combinations: - the combination (3) - (8) giving a ratio 1. 4/1 - the combinations (3) - (7) and (4) - (8) giving a ratio 1/1 - the combinations ( 4) - (7) giving a ratio 1 / 1.4
According to other embodiments, the device can be constituted by a gearbox with several ratios, by a mechanical, electric, or hydraulic speed variator.

Selon une variante, le variateur de vitesse mécanique peut être à courroie (s).  According to a variant, the mechanical speed variator can be with belt (s).

Selon une autre variante, le variateur de vitesse peut être constitué par une pompe hydraulique entraînée par la prise de force du tracteur et d'un ou plusieurs moteur hydrauliques entraînant le (s) hérisson (s), la variation de vitesse étant obtenue au moyen d'une pompe à cylindrée variable, ou d'un moteur à cylindrée variable, ou d'un régulateur de débit hydraulique installé entre la pompe et le moteur. According to another variant, the speed variator can be constituted by a hydraulic pump driven by the PTO of the tractor and one or more hydraulic motor driving the hedgehog (s), the speed variation being obtained by means a variable displacement pump, or a variable displacement motor, or a hydraulic flow regulator installed between the pump and the motor.
