La présente invention se rapporte à des machines agricoles servant àThe present invention relates to agricultural machines used for

tasser le sol après le labour.tamp the soil after plowing.

On connaît différentes machines de ce type qui comprennent un châssis pourvu de moyens pour son attela- ge au sytème de relevage trois points d'un tracteur, ledit châssis supportant des outils pour le travail du sol, par exemple, des trains de disques, des rouleaux émotteurs, des trains de pneumatiques, etc...10 Lorsque le sol est très humide, certains outils ne conviennent pas, par exemple, on ne peut utiliser les trains de disques auxquels la terre, devenue collante, adhère, entraînant un bourrage. On est donc obligé de15 prévoir plusieurs machines qui doivent être utilisées en fonction de l'état du sol, ce qui conduit à des achats coûteux. Les perfectionnements, selon l'invention, visent des machines agricoles comprenant un châssis pourvu de moyens d'attelage au système de relevage trois points d'un tracteur, ledit châssis supportant des outils pour le travail du sol, lesdits perfectionnements étant caracté- risés en ce que le châssis comporte un cadre, tandis que25 les outils sont portés par un second cadre identique à celui du châssis, des moyens étant prévus pour fixer le  Various machines of this type are known which comprise a chassis provided with means for its attachment to the three-point lifting system of a tractor, said chassis supporting tools for working the soil, for example, disc trains, lump rollers, tire trains, etc ... 10 When the ground is very wet, certain tools are not suitable, for example, one cannot use the train of discs to which the earth, which has become sticky, adheres, causing a blockage. It is therefore necessary to provide several machines which must be used depending on the condition of the soil, which leads to expensive purchases. The improvements according to the invention relate to agricultural machines comprising a chassis provided with means for coupling to the three-point lifting system of a tractor, said chassis supporting tools for working the soil, said improvements being characterized by that the chassis comprises a frame, while the tools are carried by a second frame identical to that of the chassis, means being provided for fixing the

second cadre contre la face inférieure du cadre du châssis.  second frame against the underside of the chassis frame.

Grâce à cette disposition on peut, à partir d'un même châssis, prévoir différents ensembles d'outils qui peuvent être montés sélectivement sur ledit châssis  Thanks to this arrangement, it is possible, from the same chassis, to provide different sets of tools which can be selectively mounted on said chassis.

tant une entaille destinée à recevoir le doigt et un verrou étant prévu pour bloquer les doigts dans le fond des entail- les. On réalise ainsi des moyens d'assemblage particulière-  both a notch intended to receive the finger and a lock being provided for blocking the fingers in the bottom of the notches. This produces special assembly means

ment simples.simple.

Suivant encore une autre caractéristique, les ailes de la chape comportent, le long d'un bord, un crochet et, au voisinage du bord opposé, un trou, tandis15 que le verrou est constitué d'un pivot destiné à s'insérer sous les crochets et solidaire d'une platine percée d'un  According to yet another characteristic, the wings of the yoke comprise, along one edge, a hook and, in the vicinity of the opposite edge, a hole, while the lock consists of a pivot intended to be inserted under the hooks and secured to a plate pierced with a

trou destiné à être traversé par une clavette traversant les trous des ailes de la chape.  hole intended to be crossed by a key passing through the holes of the wings of the yoke.

Enfin, la platine est solidaire d'une douille destinée à recevoir un levier. Ainsi, en agissant sur  Finally, the plate is secured to a socket intended to receive a lever. So, by acting on

le levier, on facilite la mise en place du pivot dans les entailles et on peut facilement aligner les trous pour engager la clavette. Egalement, pour le démontage25 le levier permet de faciliter le retrait de la clavette.  the lever, we facilitate the positioning of the pivot in the notches and we can easily align the holes to engage the key. Also, for dismantling25 the lever makes it easier to remove the key.

L'invention va maintenant être décrite avec plus de détails en se référant à un mode de réalisation particulier donné à titre d'exemple seulement et représenté aux dessins annexés, dans lesquels:5  The invention will now be described in more detail with reference to a particular embodiment given by way of example only and shown in the accompanying drawings, in which:

Figure 1 est une vue en perspective d'une machine agricole perfectionnée, selon l'invention.  Figure 1 is a perspective view of an improved agricultural machine according to the invention.

La machine représentée aux figures peut être une machine simple c'est-à-dire formée d'un chassis 1 comprenant un cadre rectangulaire avec, dans la partie20 médiane d'un grand côté, des pivots 2 pour l'attelage à l'avant d'un tracteur et un montant 4 supportant une chape avec un support 3 pour le troisième point du système  The machine shown in the figures can be a simple machine, that is to say formed by a chassis 1 comprising a rectangular frame with, in the middle part of a long side, pivots 2 for coupling to the front of a tractor and an upright 4 supporting a yoke with a support 3 for the third point of the system

de relevage du tracteur.lifting the tractor.

La machine peut être également du type destiné à travailler une plus grande surface et dans laquelle le châssis est formé d'un cadre principal comportant les pivots d'attelage et le support de troisième point, sur chacun des côtés du cadre s'articulant un cadre, ceux-ci30 pouvant occuper une position verticale afin que la machine ait un encombrement acceptable pour son transport sur  The machine can also be of the type intended for working a larger surface and in which the chassis is formed by a main frame comprising the hitch pivots and the third point support, on each of the sides of the frame hinging a frame , these 30 being able to occupy a vertical position so that the machine has an acceptable size for its transport on

la route.the road.

Le chassis comprend un cadre rectangulaire 6 avec deux grands côtés 8 reliés par une traverse 7 et deux petits côtés 9. Sur la face supérieure de chaque  The frame comprises a rectangular frame 6 with two long sides 8 connected by a cross-member 7 and two short sides 9. On the upper face of each

petit côté 9 est soudé perpendiculairement un doigt 10.  short side 9 is welded perpendicularly a finger 10.

On dispose de plusieurs ensemble d'outils, par exemple des trains de pneumatiques 12 ou des trains  Several sets of tools are available, for example tire trains 12 or trains

de disques, etc...of discs, etc ...

A la figure 1, on a représenté uniquement  In Figure 1, only shown

un train de pneumatiques.a set of tires.

Ces trains d'outils sont supportés par un arbre 14 tournant fou dans des paliers 15 prévus sur la surface inférieure des petits côtés 16 d'un cadre 17,  These tool trains are supported by an idle rotating shaft 14 in bearings 15 provided on the lower surface of the short sides 16 of a frame 17,

ce dernier ayant les mêmes dimensions que le cadre 6.  the latter having the same dimensions as the frame 6.

Sur chaque petit côté 16 est soudée une chape 19 présentant deux ailes 20 qui comportent, chacune, une entaille 21 s'ouvrant à la partie supérieure, le long d'un bord un crochet 22 et, au voisinage du bord opposé,  On each short side 16 is welded a yoke 19 having two wings 20 which each have a notch 21 opening at the upper part, along one edge a hook 22 and, in the vicinity of the opposite edge,

un trou 23.a hole 23.

Afin de verrouiller le cadre 17 contre la face inférieure du cadre 8, il est prévu un verrou 25 qui comprend un pivot 26 destiné à s'insérer dans les crochets 22 et qui est solidaire d'une platine 27 située dans un plan perpendiculaire au pivot et comportant, d'une part, un trou 28 et, d'autre part, une douille 29 destinée  In order to lock the frame 17 against the underside of the frame 8, a lock 25 is provided which comprises a pivot 26 intended to be inserted in the hooks 22 and which is integral with a plate 27 situated in a plane perpendicular to the pivot and comprising, on the one hand, a hole 28 and, on the other hand, a socket 29 intended

à recevoir un levier 30.to receive a lever 30.

Le cadre 17 peut comporter au moins deux man-  The frame 17 can comprise at least two man-

chons 32 destinés à recevoir des béquilles 33, les manchons étant percés d'un trou 34 pour le passage d'une goupille 36 traversant sélectivement l'un des trous 35 d'une série de trous disposés le long de la béquille 33, les béquilles  chons 32 intended to receive crutches 33, the sleeves being pierced with a hole 34 for the passage of a pin 36 selectively passing through one of the holes 35 of a series of holes arranged along the crutch 33, the crutches

permettant de maintenir le cadre 17 en position horizontale.  allowing the frame 17 to be kept in a horizontal position.

L'ensemble d'outils qu'on désire monter sur le châssis 1 est maintenu par les béquilles 33, le châssis 1 étant, par ses pivots 2 et son support 3, attelé à l'avant ou à l'arrière d'un tracteur. On amène le châssis 1 de manière que le cadre 6 vienne, sensiblement, se superposer au cadre 17 et on abaisse le châssis 1 afin que les petits côtés 9 s'insèrent entre les ailes 20 des chapes 19, puis on insère sous les crochets 22 le pivot 26, tandis qu'on met en place dans la douille 29 un levier 30 et on fait10 basculer le verrou 25 afin que le trou 28 de la platine 27 vienne s'aligner avec les trous 23 et enfin on insère dans lesdits trous une clavette 38 pourvue d'une poignée 37 et dont l'extrémité libre peut recevoir une goupille de sécurité 40. Ainsi, les deux cadres sont parfaitement  The set of tools which it is desired to mount on the chassis 1 is held by the crutches 33, the chassis 1 being, by its pivots 2 and its support 3, coupled to the front or to the rear of a tractor . The frame 1 is brought so that the frame 6 comes, substantially, to be superimposed on the frame 17 and the frame 1 is lowered so that the short sides 9 are inserted between the wings 20 of the yokes 19, then one inserts under the hooks 22 the pivot 26, while a lever 30 is placed in the socket 29 and the latch 25 is tilted so that the hole 28 of the plate 27 comes to align with the holes 23 and finally a key 38 provided with a handle 37 and the free end of which can receive a safety pin 40. Thus, the two frames are perfectly

solidaires.united.

On conçoit que le changement d'ensemble d'outils est rapide et qu'une telle disposition est particulièrement économique. Si la machine est du type avec un cadre princi- pal et deux cadres latéraux, on prévoit, bien entendu, trois ensembles d'outils correspondant, chacun, à l'un des cadres et se fixant de la même manière que dans l'exem-25 ple décrit, par exemple, les outils pourraient être diffé- rents de ceux représentés, on pourrait prévoir des rouleaux  It is understood that the change of set of tools is rapid and that such an arrangement is particularly economical. If the machine is of the type with a main frame and two side frames, of course, three sets of tools are provided, each corresponding to one of the frames and fixed in the same way as in the example. -25 ple described, for example, the tools could be different from those shown, we could provide rollers

émotteurs, des griffes, des dents, etc...  lump breakers, claws, teeth, etc.

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit et repré- senté. On pourra y apporter de nombreuses modifications  Of course, the invention is not limited to the embodiment which has just been described and shown. We can make many modifications

de détail sans sortir pour cela du cadre de l'invention.  detail without departing from the scope of the invention.
