Abstract

The device is connected to the front of a tractor to assist in earth levelling, and has two twin wheels (2) smaller in diameter than the front wheels of the tractor. These are carried by a frame which can be adjusted so that the front wheels are lifted from contact with the ground, and the earth tends to be squeezed between the twin wheels. This frame (1) has a base (3) attached by hinges (4) forming a horizontal pivot axis and has a rectangular structure (7) at the rear, tilting about a parallel axis (8), which also forms the connection with the tractor. At the centre is a traction bar (9) attached by a hinge to the top of the structure and at the other end to a vertical wishbone (5), the whole forming a parallelogram linkage. This linkage is then swung by a diagonal double action piston and cylinder (11) so that the front of the tractor is lifted, and all the weight is supported by the twin wheels.

Description

La pressente invention a pour objet un aprareil destiné à aplanir le sol pour l'agriculture, Avant les semis par exemple, il faut niveler le sol et assurer un tassement régulier pour avoir une terre unie. On dispose actuellement de différents dispositifs qui ne donnent pas satisfaction, notamment parce que le sol ntest pas tassé entre les roues des tracteurs. The present invention relates to an apparatus intended for leveling the soil for agriculture. Before sowing, for example, it is necessary to level the soil and ensure regular compaction in order to have a smooth soil. There are currently various devices which are not satisfactory, in particular because the ground is not packed between the wheels of the tractors.

L'appareil selon l'invention remédie à ces inconvénients.  The apparatus according to the invention overcomes these drawbacks.

Il est constitué d'un chassis en fers cornitres sous lequel sont disposées quatre roues munies de pneu matiques, montées sur un support articulé sur le chassis pour pourvoir pivoter autour d'un axe horizontal, d'un cadre vertical également en cornière articulé à l'une des extrémités du chassis, destiné à venir se fixer à l'avant dtun tracteur, au sommet de ce cadre vertical et en son milieu est articulé un tirant dont l'autre extrémité est également articulée et fixée à l'extrémité supérieure d'une potencidont le pied est soudé sur le support articulé portant les roues de façon à réaliser un parallélogramme.A l'intérieur du parallélogramme formé par 1? chassis, la cadre vertical, le tirant et la potence, est disposé un vérin hydraulique à double effet prenant appui, dtune part, au sommet du cadre vertical et d'autre part sur le chassis par l'intermédiaire d'une entretoise. I1 faut noter également que les roues sont jumelées, et quelles sont directrices
A cet effet une barre d'accouplement solidarise leur bielle de connexion à la colonne de direction du tracteur0 Cette disposition permet de remplacer la direction du tracteur et de diriger l'appareil lorsqu'il est en fonctionnement comme il sera décrit plus loin.Sur l'avant du chassis des points d'attache sont également prévus pour disposer, par exemple, une nive lieuse. It consists of a frame in iron bars under which are arranged four wheels fitted with matt tires, mounted on a support articulated on the chassis to provide pivoting around a horizontal axis, a vertical frame also in angle articulated with the 'one of the ends of the chassis, intended to be fixed to the front of a tractor, at the top of this vertical frame and in the middle is articulated a tie rod whose other end is also articulated and fixed to the upper end of a potencidont the foot is welded on the articulated support carrying the wheels so as to achieve a parallelogram. Inside the parallelogram formed by 1? chassis, the vertical frame, the tie rod and the stem, is arranged a double-acting hydraulic cylinder bearing, on the one hand, at the top of the vertical frame and on the other hand on the chassis via a spacer. It should also be noted that the wheels are paired, and which are steerable
To this end, a coupling rod secures their connecting rod to the tractor steering column. This arrangement makes it possible to replace the steering of the tractor and to steer the device when it is in operation as will be described later. 'front of the chassis attachment points are also provided to have, for example, a level binder.

Ltinvention sera mieux comprise à la lecture de la description qui suit d'une réalisation de l'inven- tion et à l'examen des dessins annexés sur lesquels
- La figure 1 est une vue en perspective de l'appareil selon l'invention.The invention will be better understood on reading the following description of an embodiment of the invention and on examining the appended drawings in which
- Figure 1 is a perspective view of the apparatus according to the invention.

- - La figure 2 est une vue en perspective et schématique montrant ltappareil lorsqu'il est en fonctionnement
En se reportant à la fifre 1 on voit que l'appareil selon ltinvention est constitué dtun chassis 1, rectangUelaire réalisé en fers cornièrese Sous ce chassis 1, sont disposées quatre roues jumelées et munies de pneumatiques 2. Ces roues 2, sont montées sur un support 3 articulé autour axe axe 4, horizontal fixé sous le chassis 1. Sur ce support 3 est soudée une potence verticale 5, dont la partie supérieure est munie d'orifices de fixation 6.Sur le chassis 1, est articulé un cadre vertical 7, également réalisé en fers cornières destiné à venir se fixer sur lavant d'un tracteur. Ce cadre vertical 7 est articulé sur le chassis 1, autour de l'axe 8.- - Figure 2 is a perspective and schematic view showing the device when in operation
Referring to the fife 1 we see that the device according to the invention consists of a chassis 1, rectangular made of angle irons. Under this chassis 1, four twin wheels are provided and provided with tires 2. These wheels 2 are mounted on a support 3 articulated around axis axis 4, horizontal fixed under the chassis 1. On this support 3 is welded a vertical bracket 5, the upper part of which is provided with fixing holes 6. On the chassis 1, a vertical frame 7 is articulated , also made of angle irons intended to be fixed on the front of a tractor. This vertical frame 7 is articulated on the chassis 1, around the axis 8.

Au sommet de ce cadre 7 et en son milieu est également articulé d'une part, un tirant 9, dont l'extrémité 10, est fixée au sommet de la potence 5, au moyen d'un boulon passant dans l'un des orifices de fixation 6, et d'autre part un vérin à double effet Il, la tige 12, du piston est fixée sur le chassis 1 par ltin- termédiaire dtune entretoise 13, Les roues 2 étant directrices les bielles de connexion 14 et 15 sont reliées par une barre d'accouplement 16 au dispositif de direction du tracteur, non représenté.Bien entendu la timonerie. comporte des renvois de mouvement et autres dispositifs connus qui ne sont pas décrits, mais qui sont nécessaires à la direction correcte de l'appa- reil. A l'avant du chassis 1 des dispositifs de fixation 1718 d'outils sont prévus afin de pouvoir faire précéder lssappa- reil selon ltinvention, par exemple, par une niveleuse ou toute autre machine. At the top of this frame 7 and in the middle is also articulated on the one hand, a tie rod 9, the end of which 10, is fixed to the top of the bracket 5, by means of a bolt passing through one of the orifices 6, and on the other hand a double-acting cylinder II, the rod 12, of the piston is fixed to the chassis 1 by means of a spacer 13, the wheels 2 being directing the connecting rods 14 and 15 are connected by a coupling bar 16 to the steering device of the tractor, not shown. Of course the wheelhouse. includes movement references and other known devices which are not described, but which are necessary for the correct direction of the apparatus. At the front of the chassis 1, fixing devices 1718 for tools are provided in order to be able to precede the apparatus according to the invention, for example, by a grader or any other machine.

Rn se reportant à la figure 2 montrant l'appareil en fonctionnement, en perspective avec vue partielle et schématique du tracteur on voit que sous ltaction du vérin 11, les roues jumelées 2, sont appuyées fortement sur le sol, d'autant que l'action dudit vérin 11, provoque le soulévement du train avant de tracteur ce qui a pour effet de reporter tout son poids sur le chassis 1, de l'appareil0
Dans cette position la direction est assurée par les roues jumelées 2 solidaires de la direction de tracteur par la barre dtaccouplement 16.Rn referring to FIG. 2 showing the device in operation, in perspective with a partial and schematic view of the tractor, it can be seen that under the action of the jack 11, the twin wheels 2 are strongly supported on the ground, especially as the action of said cylinder 11, causes the front axle of the tractor to be raised, which has the effect of transferring its entire weight to the chassis 1 of the apparatus 0
In this position, steering is ensured by the twin wheels 2 secured to the tractor steering by the coupling bar 16.

Pour le déplacement de l'ensemble sur la route la rétraction du vérin 11, provoque la remontée de ltap- rareil par pivotement autour de l'axe 8, et en même temps les roues avant du tracteur prennent appui de nouveau sur le sol. For the displacement of the assembly on the road, the retraction of the jack 11 causes the device to rise by pivoting about the axis 8, and at the same time the front wheels of the tractor rest again on the ground.

3 ion entendu l'appareil peut comporter d'autres perfectionnements. Par exemple, un dispositif de firation sur le tracteur différent, de même que lavant du chassis peut être modifié pour disposer toute machine travaillant le sol sans pour cela s'écarter du cadre de la présente invention.  3 ion heard the device may include other improvements. For example, a device of firation on the different tractor, as well as the front of the chassis can be modified to arrange any machine working the soil without for this departing from the scope of the present invention.
