Description
<Desc/Clms Page number 1> <Desc / Clms Page number 1>
La présente invention est relative à un rouleau d'appui notamment pour les outils de préparation du sol. The present invention relates to a support roller, in particular for soil preparation tools.
A l'arrière des outils pour préparer le sol en vue d'obtenir un lit de semences superficiel à tassement homogène et régulier, on dispose très généralement un rouleau soit monobloc, soit constitué de plusieurs éléments identiques comme des disques métalliques assez épais qui sont montés sur un axe de rotation commun. At the rear of the tools for preparing the soil in order to obtain a surface seed bed with homogeneous and regular compaction, there is very generally a roller, either monobloc, or made up of several identical elements like fairly thick metal discs which are mounted on a common axis of rotation.
De tels rouleaux présentent comme principal inconvénient de ne pas permettre un tassement régulier et homogène quelle que soit la nature du terrain. The main disadvantage of such rollers is that they do not allow regular and homogeneous compaction whatever the nature of the ground.
En effet, dès que le terrain présente des aspérités non friables telles que des pierres, les rouleaux connus prennent appui sur de telles aspérités, ce qui les déstabilisent et conduit à un tassement irrégulier en particulier. Indeed, as soon as the ground has non-friable roughness such as stones, the known rollers bear on such roughness, which destabilize them and leads to irregular settlement in particular.
Aussi un des buts de la présente invention est-il de fournir un rouleau d'appui notamment pour les outils de préparation du sol qui permet d'obtenir un tassement régulier et homogène quelle que soit la nature du terrain. One of the aims of the present invention is therefore to provide a support roller, in particular for soil preparation tools, which makes it possible to obtain regular and homogeneous compaction whatever the nature of the ground.
Un autre but de l'invention est de fournir un tel rouleau qui reste efficace quelles que soient les conditions météorologiques. Another object of the invention is to provide such a roller which remains effective whatever the weather conditions.
Ces buts, ainsi que d'autres qui apparaîtront par la suite, sont atteints par un rouleau d'appui notamment pour les outils de préparation du sol comprenant, d'une part, un élément support qui est constitué par deux longerons horizontaux, parallèles entre eux et déterminant un plan sensiblement vertical et qui comporte des moyens d'attelage, et, d'autre part, une pluralité d'éléments rotatifs montés sur cet élément support, qui est, selon la présente invention, caractérisé par le fait que chaque élément rotatif est constitué par une roue à bandage en un matériau souple et est relié au longeron supérieur par un dispositif amortisseur et que les axes de rotation des éléments rotatifs sont disposés dans le prolongement les uns des autres. These aims, as well as others which will appear subsequently, are achieved by a support roller, in particular for soil preparation tools comprising, on the one hand, a support element which is constituted by two horizontal beams, parallel between them and determining a substantially vertical plane and which comprises coupling means, and, on the other hand, a plurality of rotary elements mounted on this support element, which is, according to the present invention, characterized in that each element rotary is constituted by a wheel with a bandage in a flexible material and is connected to the upper spar by a damping device and that the axes of rotation of the rotary elements are arranged in the extension of each other.
Avantageusement, chaque dispositif amortisseur est constitué, d'une part, par un ressort à lames dont une extrémité est solidaire du longeron supérieur et, d'autre part, par un étrier dans lequel l'élément rotatif correspondant est disposé libre en rotation et dont le sommet est solidaire de l'autre extrémité du ressort à lames. Advantageously, each damping device is constituted, on the one hand, by a leaf spring, one end of which is integral with the upper spar and, on the other hand, by a bracket in which the corresponding rotary element is disposed free in rotation and whose the top is secured to the other end of the leaf spring.
La description qui va suivre et qui ne présente aucun caractère limitatif, doit être lue en regard des figures annexées, parmi lesquelles : The description which follows and which is in no way limiting, should be read with reference to the appended figures, among which:
<Desc/Clms Page number 2><Desc / Clms Page number 2>
- la figure 1 est une vue en perspective arrière d'un rouleau d'appui selon la présente invention ; et, - la figure 2 est une vue en coupe verticale selon la ligne 11-il de la figure 1. - Figure 1 is a rear perspective view of a support roller according to the present invention; and, - Figure 2 is a vertical sectional view along line 11-il of Figure 1.
Afin de permettre une bonne compréhension du positionnement dans l'espace du rouleau d'appui selon la présente invention, on considérera ce rouleau d'appui comme perpendiculaire à la direction d'avancement indiquée par la flèche F sur chaque figure. In order to allow a good understanding of the positioning in space of the support roller according to the present invention, this support roller will be considered to be perpendicular to the direction of advance indicated by the arrow F in each figure.
Ainsi qu'on peut le voir sur ces figures, un rouleau d'appui, désigné dans son ensemble par la référence 1, comprend, d'une part, un élément support 2 et, d'autre part, une pluralités d'éléments rotatifs 3 montés sur cet élément support 2. As can be seen in these figures, a support roller, designated as a whole by the reference 1, comprises, on the one hand, a support element 2 and, on the other hand, a plurality of rotary elements 3 mounted on this support element 2.
Cet élément support 2 est constitué par deux longerons horizontaux 4 et 5, parallèles entre eux, déterminant un plan sensiblement vertical : le longeron inférieur est référencé 4 et le longeron supérieur 5. This support element 2 is constituted by two horizontal beams 4 and 5, parallel to each other, determining a substantially vertical plane: the lower beam is referenced 4 and the upper beam 5.
Selon la présente invention, chaque élément rotatif 3 est constitué par une roue à bandage en un matériau souple et est relié au longeron supérieur 5 par un dispositif amortisseur 6. According to the present invention, each rotary element 3 is constituted by a wheel with a tire made of a flexible material and is connected to the upper beam 5 by a damping device 6.
Chaque dispositif amortisseur 6 est constitué, d'une part, par un ressort à lames 7 dont une extrémité est solidaire du longeron supérieur 5 et, d'autre part, par un étrier 8 dans lequel l'élément rotatif 3 correspondant est disposé libre en rotation et dont le sommet est solidaire de l'autre extrémité du ressort à lames 7. Each damping device 6 is constituted, on the one hand, by a leaf spring 7, one end of which is integral with the upper beam 5 and, on the other hand, by a stirrup 8 in which the corresponding rotary element 3 is arranged free rotation and the top of which is secured to the other end of the leaf spring 7.
Les axes de rotation 9 de chaque élément rotatif 3 sont disposés dans le prolongement les uns des autres. The axes of rotation 9 of each rotary element 3 are arranged in the extension of each other.
Le rouleau d'appui 1 comporte bien évidemment des moyens d'attelage sur un outil agricole : ceux-ci étant bien connus de l'homme du métier et hors de la portée de la présente invention ne sont pas décrits plus avant. The support roller 1 obviously includes coupling means on an agricultural implement: these being well known to those skilled in the art and outside the scope of the present invention are not described further.
Les éléments rotatifs 3 qui sont donc montés chacun sur une suspension à ressort grâce au dispositif amortisseur 6, sont indépendants les uns des autres : la charge par élément rotatif reste donc constante et ce indépendamment du relief du sol. En conséquence le tassement obtenu par la mise en oeuvre du rouleau d'appui 1 est uniforme et indépendant du relief du sol. The rotary elements 3 which are therefore each mounted on a spring suspension thanks to the damping device 6, are independent of each other: the load per rotary element therefore remains constant and this independently of the relief of the ground. Consequently, the compaction obtained by the implementation of the support roller 1 is uniform and independent of the relief of the ground.
Le tassement, étant constant, assure par là-même un lit de semence homogène qui permet au semoir d'implanter les semences à profondeur régulière et ainsi une levée homogène de celles-ci. The settlement, being constant, ensures by this a homogeneous seed bed which allows the seed drill to plant the seeds at regular depth and thus a homogeneous lifting of these.
