Abstract
Description
L'invention se rapporte à une machine d'épandage centrifuge de matériaux liquides ou pâteux ou particulaires sur une surface de réception. The invention relates to a machine for centrifugal spreading of liquid or pasty or particulate materials on a receiving surface.
Pour amender des terres agricoles ou encore pour épandre des produits tels du sel sur toute autre surface telle celle des voies de circulation, on fait généralement appel à des dispositifs d'épandage centrifuge. Centrifugal spreading devices are generally used to amend agricultural land or to spread products such as salt on any other surface such as that of traffic lanes.
Classiquement, un tel dispositif d'épandage comprend
- une réserve de matériau en forme de trémie portée par un chassis pourvu d'organes de roulement et,
- des moyens de distribution contrôlée sur une surface réceptrice du matériau contenu dans la réserve.Conventionally, such a spreading device comprises
- a reserve of material in the form of a hopper carried by a chassis provided with rolling members and,
- means of controlled distribution on a receiving surface of the material contained in the reserve.
Ces moyens de distribution comprennent au moins un dispositif de projection centrifuge, d'axe de rotation sensiblement perpendiculaire à la surface de réception, lequel dispositif de projection consiste en au moins une lame de projection qui est montée au moins radialement à l'axe de rotation et ce, au dessus d'un disque sur lequel chute le matériau provenant de la trémie, cette lame projetant le dit matériau dans un secteur circulaire prédéterminé défini par un carter qui à cet effet n'entoure que partiellement le disque de manière à dévier le matériau projeté et à limiter la projection au secteur dépourvu de carter. These distribution means comprise at least one centrifugal projection device, with an axis of rotation substantially perpendicular to the receiving surface, which projection device consists of at least one projection blade which is mounted at least radially to the axis of rotation. and this, above a disc onto which the material from the hopper falls, this blade projecting said material into a predetermined circular sector defined by a casing which for this purpose only partially surrounds the disc so as to deflect the projected material and to limit the projection to the sector without casing.
Le disque peut être distinct des lames de projection mais, plus généralement, il est solidaire en rotation de celles-ci. The disc may be separate from the projection blades but, more generally, it is integral in rotation with the latter.
Clssiquement, le dispositif de projection est porté par une table sur ou sous laquelle sont montés
- d'une part, les moyens d'entrainement en rotation notamment des lames de projection et,
- d'autre part, le carter fixe.Conventionally, the projection device is carried by a table on or under which are mounted
on the one hand, the means for driving in rotation in particular projection blades and,
- on the other hand, the fixed casing.
Cette table permet en outre de protéger des poussières le système d'entrainement et, par exemple, les courroies de transmission ou les circuits d'alimentation d'un moteur hydraulique. This table also makes it possible to protect the drive system and, for example, the transmission belts or the supply circuits of a hydraulic motor from dust.
Ces moyens d'entrainement pouvant être de tout type connu ne limitent pas l'objet de l'invention. These drive means which can be of any known type do not limit the subject of the invention.
Bien entendu, il est prévu un jeu de fonctionnement tant entre le carter et la périphérie du disque qu'entre la face inférieure du disque et la face supérieure de la table. Of course, an operating clearance is provided both between the casing and the periphery of the disc and between the underside of the disc and the top face of the table.
Bien que le jeu de fonctionnement soit notamment réduit entre le carter et le disque, le matériau peut s'infiltrer au travers de l'interstice et venir s'accumuler entre le dessus de table et le dessous du disque. Although the operating clearance is notably reduced between the casing and the disc, the material can seep through the gap and accumulate between the table top and the bottom of the disc.
La vitesse d'accumulation dépend de la fluidité du matériau et, par exemple, de sa granulométrie voire des influences extérieures telles le sens du vent qui, lorsqu'il est contraire, peut chasser des particules légères entre le disque et la table. The speed of accumulation depends on the fluidity of the material and, for example, its particle size or even external influences such as the direction of the wind which, when it is contrary, can drive away light particles between the disc and the table.
I1 est certes possible de procéder périodiquement à une opération de nettoyage de l'espace délimité par le disque et la table mais cette périodicité est difficilement estimable car les matériaux à épandre ont des caractéristiques physiques trés différentes que ce soit la granulométrie ou l'humidité ainsi que les conditions d'épandage. It is certainly possible to periodically carry out an operation of cleaning the space delimited by the disc and the table, but this periodicity is difficult to estimate since the materials to be spread have very different physical characteristics, be it particle size or humidity as well. than the spreading conditions.
I1 est possible de solliciter de la part de l'utilisateur un nettoyage systématique mais cela ne garantit pas son application stricte d'où malgré tout un risque d'incidents techniques. It is possible to request from the user a systematic cleaning, but this does not guarantee its strict application, which nevertheless leads to a risk of technical incidents.
Ces interventions immobilisent en outre le distributeur ce qui en limite la rentabilité. These interventions also immobilize the distributor, which limits profitability.
Un des résultats que l'invention vise à obtenir est une machine du type cité ci-dessus qui remédie à ces inconvénients. One of the results which the invention aims to obtain is a machine of the type mentioned above which overcomes these drawbacks.
A cet effet, elle a pour objet une telle machine d'épandage notamment caractérisée en ce que le dispositif de projection comprend, entre la face inférieure du disque et la face supérieure de la table, au moins une raclette qui, périodiquement, racle la surface supérieure de la table de manière à éliminer les impuretés qui auraient pu sty accumuler. To this end, it relates to such a spreading machine, in particular characterized in that the projection device comprises, between the lower face of the disc and the upper face of the table, at least one squeegee which periodically scrapes the surface. top of the table so as to remove any impurities that may have accumulated.
L'invention sera bien comprise à l'aide de la description ci-aprés faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement
- figure 1 : une vue partielle d'une machine d'épandage,
- figure 2 : une vue en coupe d'un détail de la machine d'épandage. The invention will be better understood with the aid of the description below given by way of nonlimiting example with regard to the attached drawing which schematically represents
- Figure 1: a partial view of a spreading machine,
- Figure 2: a sectional view of a detail of the spreading machine.
En se reportant au dessin, on voit que, pour épandre sur une surface réceptrice 1 un matériau quelconque, on fait appel à une machine 2 d'épandage centrifuge qui comprend
- une réserve 3 de matériau en forme de trémie portée par un chassis 4 pourvu d'organes 5 de roulement et,
- des moyens 6 de distribution contrôlée sur la surface réceptrice du matériau contenu dans la réserve.Referring to the drawing, it can be seen that, in order to spread any material on a receiving surface 1, use is made of a machine 2 for centrifugal spreading which comprises
a reserve 3 of hopper-shaped material carried by a chassis 4 provided with rolling members 5 and,
- Means 6 of controlled distribution on the receiving surface of the material contained in the reserve.
Ces moyens de distribution comprennent au moins un dispositif 7 de projection centrifuge d'axe 7a de rotation sensiblement perpendiculaire à la surface de réception, lequel dispositif 7 de projection consiste en au moins une lame 8 de projection qui, montée au moins sensiblement radialement à l'axe de rotation et ce, au dessus d'un disque 9 sur lequel chute le matériau provenant de la trémie, projette le dit matériau dans un secteur circulaire prédéterminé défini par un carter 10 qui entoure partiellement le disque de manière à dévier le matériau projeté et à limiter la projection au secteur dépourvu de carter. These distribution means comprise at least one centrifugal projection device 7 of axis 7a of rotation substantially perpendicular to the receiving surface, which projection device 7 consists of at least one projection blade 8 which, mounted at least substantially radially to the axis of rotation, above a disc 9 onto which the material from the hopper falls, projects the said material into a predetermined circular sector defined by a housing 10 which partially surrounds the disc so as to deflect the projected material and to limit the projection to the sector without casing.
Le disque 9 peut être distinct des lames de projection mais, plus généralement, il est solidaire en rotation de celles-ci. The disc 9 can be separate from the projection blades but, more generally, it is integral in rotation with the latter.
Le dispositif de projection est alimenté en matériau par des moyens d'alimentation tels des tapis, des vis sans fin dirigeant directement ou via un broyeur le matériau vers une trappe 12 de dosage surplombant le dispositif de projection. The projection device is supplied with material by supply means such as belts, endless screws directing the material directly or via a grinder to a metering hatch 12 overhanging the projection device.
Classiquement, le dispositif de projection est porté par une table 13 sur ou sous laquelle sont montés, d'une part, les moyens 14 d'entrainement en rotation des lames de projection et, d'autre part, le carter 10, ceci de manière à préserver un jeu de fonctionnement tant entre le disque et le carter qu'entre le dessous du disque et le dessus de la table. Conventionally, the projection device is carried by a table 13 on or under which are mounted, on the one hand, the means 14 for rotating the projection blades and, on the other hand, the casing 10, so to preserve a working clearance both between the disc and the casing and between the underside of the disc and the top of the table.
Selon l'invention, le dispositif 7 de projection comprend entre la face inférieure 9a du disque 9 et la face supérieure 13a de la table 13 au moins une raclette 15 qui, périodiquement, racle la surface supérieure de la table de manière à éliminer les impuretés qui auraient pu sty accumuler. According to the invention, the projection device 7 comprises between the lower face 9a of the disc 9 and the upper face 13a of the table 13 at least one squeegee 15 which periodically scrapes the upper surface of the table so as to remove the impurities who could have sty accumulated.
La raclette 15 est, de préférence, en matériau élastiquement déformable. The squeegee 15 is preferably made of an elastically deformable material.
Avantageusement, la raclette 15 est montée radialement sur un support 16 d'axe de rotation coaxial à celui des lames de projection. Advantageously, the squeegee 15 is mounted radially on a support 16 with an axis of rotation coaxial with that of the projection blades.
Dans une forme préférée de réalisation, c'est le disque 9 du dispositif de projection qui fait office de support pour le raclette qui est alors entraînée en rotation en même temps que les lames de projection. In a preferred embodiment, it is the disc 9 of the projection device which acts as a support for the squeegee which is then driven in rotation at the same time as the projection blades.
De préférence, il est prévu plusieurs raclettes réparties angulairement autour de l'axe de rotation. Preferably, several squeegees are provided angularly distributed around the axis of rotation.
Ces raclettes sont, soit fixées à l'aplomb des lames de projection, soit décalées angulairement par rapport à ces lames d'une valeur égale au demi-angle au sommet défini entre deux lames de projection consécutives. These squeegees are either fixed vertically to the projection blades, or angularly offset with respect to these blades by a value equal to the half-angle at the apex defined between two consecutive projection blades.
Ces dispositions techniques constituent globalement un dispositif de nettoyage périodique de la surface de la table et concourent également à la projection et donc à la récupération du matériau ainsi extrait sans nuire à la qualité de la répartition. These technical provisions generally constitute a device for periodic cleaning of the table surface and also contribute to the projection and therefore to the recovery of the material thus extracted without harming the quality of the distribution.
Le jeu de fonctionnement entre le disque et le carter peut alors être plus important d'où une fabrication moins onéreuse sans que cela affecte la qualité de l'épandage. The operating clearance between the disc and the casing can then be greater, hence less costly manufacturing without affecting the quality of the spreading.
Dans une variante de réalisation de l'invention, la table 13 est articulée autour d'un axe transversal 17 au sens 18 de déplacement de la machine d'épandage de sorte qu'on puisse modifier l'angle dièdre entre le plan P de la nappe projetée et celui Y de la surface de réception. In an alternative embodiment of the invention, the table 13 is articulated around a transverse axis 17 in the direction 18 of movement of the spreading machine so that the dihedral angle between the plane P of the projected water table and that Y of the receiving surface.
