Abstract

Device for removing the earth adhering to an agricultural implement, such as a roller 1 equipped with teeth, consisting of a plurality of flexible blades 6, the free ends 7 of which are pressed against the periphery of said roller.

Description

La présente invention est relative à un dispositif pour enlever la terre adhérant à un outil agricole tel que ceux dénommés " rouleau Paker
Actuellement, préalablement à l'ensemencement,on ameublit la terre à l'aide d'une herse alternative ou autre qui permet d'obtenir une terre meuble sur une profondeur d'environ quinze centimètres.
The present invention relates to a device for removing soil adhering to an agricultural tool such as those called "roller Paker
Currently, prior to sowing, the soil is loosened using an alternative harrow or another which makes it possible to obtain loose soil to a depth of approximately fifteen centimeters.

L'expérience a montré que la terre étant alors trop meuble les graines étaient trop enterrées, c'est pourquoi on a placé un rouleau Paker derrière la herse. Un tel rouleau se présente sous la forme d'un cylindre d'environ trente centimètres de diamètre roulant sur le sol et comportant des dents qui pénètrent dans le sol, sur une profondeur de l'ordre de sept à huit centimètres. Experience has shown that the soil being too loose then the seeds were too buried, which is why a Paker roller was placed behind the harrow. Such a roller is in the form of a cylinder of about thirty centimeters in diameter rolling on the ground and comprising teeth which penetrate into the ground, to a depth of the order of seven to eight centimeters.

Certaines terres collent au rouleau et remplissent l'es- pace libre entre ses dents, le rendant ainsi inapte à la fonction pour laquelle il a été conçu
I1 faut donc enlever cette terre et, à cet effet, les rouleaux sont munis de décrottoirs.
Some soils stick to the roller and fill the free space between its teeth, making it unsuitable for the function for which it was designed
It is therefore necessary to remove this earth and, for this purpose, the rollers are provided with scrapers.

En l'état actuel de la technique, un décrottoir est constitué par une pluralité de lames rigides s'étendant entre les dents, disposées près du sol derrière le rouleau et fixées sur une barre transversale. Chaque lame présente au moins une lumière oblongue trayersée par la vis de fixation à la barre et permettant son réglage par rapport à la périphérie du rouleau. In the current state of the art, a scraper is constituted by a plurality of rigid blades extending between the teeth, arranged close to the ground behind the roller and fixed on a transverse bar. Each blade has at least one oblong lumen trayersée by the screw fixing to the bar and allowing its adjustment relative to the periphery of the roller.

Un tel dispositif ne donne pas satisfaction. En effet, pour être efficaces, les lames doivent racler le rouleau c'està-dire être en contact avec lui pour décoller la couche de terre mais un tel contact est impossible à réaliser avec les rouleaux actuels qui se présentent sous la forme de cylindres grossiers sur lesquels les dents sont soudées. En effet, on a constaté que pour une section donnée, celle-ci n'est pas rigoureusement circulaire mais présente des variations de diamètre qui peuvent atteindre un centimètre.  Such a device is not satisfactory. Indeed, to be effective, the blades must scrape the roller, that is to say be in contact with it to peel off the layer of soil, but such contact is impossible to achieve with current rollers which are in the form of coarse cylinders on which the teeth are welded. Indeed, it has been found that for a given section, it is not strictly circular but has variations in diameter which can reach one centimeter.

Dans ces conditions, durant la rotation, les lames ne sont pas en contact permanent avec le rouleau.Lorsqu'un jeu apparaît entre le rouleau et la lame on a constaté que la terre se trouve comprimée entre celle-ci et ledit rouleau. Ce phénomène de bourrage engendre des forces supérieures à celles de serrage qui maintiennent les lames sur la barre porteuse et cellesci sont repoussées en augmentant d'autant l'espace existant entre leur extrémité et ledit rouleau. Dans d'autres cas, on a constaté un blocage de la rotation du rouleau qui glisse alors sur le sol avec tous les inconvénients que cela présente. Under these conditions, during rotation, the blades are not in permanent contact with the roller. When a clearance appears between the roller and the blade, it has been found that the earth is compressed between the latter and said roller. This jamming phenomenon generates forces greater than those of clamping which hold the blades on the carrier bar and these are pushed back by increasing the space existing between their end and said roller. In other cases, there has been a blockage of the rotation of the roller which then slides on the ground with all the disadvantages that this presents.

La présente invention qui remédie à ces inconvénients est remarquable en ce qu'on utilise des lames élastiquement déformables dont l'extrémité de chacune est appliquée contre la périphérie du rouleau. The present invention which overcomes these drawbacks is remarkable in that elastically deformable blades are used, the end of each of which is applied against the periphery of the roller.

La présente invention sera mieux comprise par la description qui va suivre faite en se référant au dessin annexé à titre d'exemple indicatif seulement sur lequel
La figure 1 est une vue en coupe verticale d'un rouleau équipé du dispositif de l'invention ;
La figure 2 est la vue de dessus, partielle, de la figure 1;
La figure 3 est une vue partielle en perspective montrant la fixation des lames flexibles surale bâti.
The present invention will be better understood from the description which follows made with reference to the accompanying drawing by way of indicative example only, in which
Figure 1 is a vertical sectional view of a roller equipped with the device of the invention;
Figure 2 is the partial top view of Figure 1;
Figure 3 is a partial perspective view showing the attachment of the flexible surale built blades.

En se reportant au dessin on voit que, de la façon connue, le rouleau est constitué par un tube 1 cylindrique, à la périphérie duquel sont fixées des dents 2. Le tube 1 est traversé, en son centre, par un arbre 3 porté par les ailes 4 du bâti 5.Le bâti 5 est porté par un tracteur agricole à l'aide de moyens connus, donc non représentés. Referring to the drawing we see that, in known manner, the roller is constituted by a cylindrical tube 1, at the periphery of which are fixed teeth 2. The tube 1 is crossed, in its center, by a shaft 3 carried by the wings 4 of the frame 5. The frame 5 is carried by an agricultural tractor using known means, therefore not shown.

Selon l'invention, le bâti 5 porte des lames 6 flexibles, réalisées par exemple en acier à ressort et dont les extrémités 7 sont appliquées en pression contre la périphérie du tube l.  According to the invention, the frame 5 carries flexible blades 6, made for example of spring steel and whose ends 7 are applied under pressure against the periphery of the tube l.

De cette façon, les lames sont toujours en contact avec le tube l meme si celui-ci n'est pas rigoureusement cylindrique. In this way, the blades are always in contact with the tube l even if the latter is not strictly cylindrical.

Selon une autre caractéristique de l'invention, les lames sont montées pivotantes sur un arbre 8, porté par le bâti 5, parallèle à l'axe de rotation du rouleau 1. En faisant pivoter les lames en sens inverse à la rotation du rouleau (Flèche F1) on applique les extrémités 7 de ces dernières contre ledit rouleau. According to another characteristic of the invention, the blades are pivotally mounted on a shaft 8, carried by the frame 5, parallel to the axis of rotation of the roller 1. By rotating the blades in the opposite direction to the rotation of the roller ( Arrow F1) the ends 7 of the latter are applied against said roller.

A cet effet et selon un mode de réalisation, les lames
6 s'étendent en 9 au-delà de l'arbre 8. Chaque extension 9, ainsi formée, présente un taraudage de réception dlune vis 1O.
For this purpose and according to one embodiment, the blades
6 extend at 9 beyond the shaft 8. Each extension 9, thus formed, has a thread for receiving a screw 1O.

De ce fait, on comprend que lors de la rotation de la vis lO sa tête prend appui contre le bâti 5 ce qui détermine la rotation de la lame, selon la flèche F2.Therefore, it is understood that during the rotation of the screw lO its head bears against the frame 5 which determines the rotation of the blade, according to arrow F2.

Bien entendu, la présente invention ne se limite pas au mode de réalisation décrit et représenté mais s'étend, au contraire, à toutes variantes de formes, matières et dimensions.  Of course, the present invention is not limited to the embodiment described and shown, but extends, on the contrary, to all variants of shapes, materials and dimensions.
