Abstract

The distributor comprises a tank pulled by a tractor. At the rear, the manure is discharged through a single outlet pipe (7). This reduces in diameter as it approaches the discharge opening and terminates in a neck downturned at 90 degrees. Immediately below the neck is a tray (8), its inclination to the opening being regulated between 45 and 135 degrees by an adjustable bracket (10). Its rear has a vertical side wall (12) and an inturned lip (13); its front slopes upwards to a shallow lip (19). It is placed at a low height to avoid undue dispersion of the liquid in the air.

Description

La présente invention concerne le domaine du matériel agricole, en particulier des tonnes à lisier, et a pour objet un dispositif d'épandage de lisier pour de telles tonnes. The present invention relates to the field of agricultural equipment, in particular tonnes of slurry, and relates to a device for spreading slurry for such tonnes.

Actuellement, les dispositifs d'épandage de lisier connus, montés à I'arriere d'une tonne à lisier, et permettant l'épandage du lisier sur le champ, sont conçus de manière à permettre l'obten- tion d'une importante largeur d'épandage. Un tel résultat est possible par application des règles de la balistique, qui consistent à diriger le jet en hauteur au moyen d'une plaque inclinée par rapport à l'horizontale, et sur laquelle ledit jet de lisier est propulsé sous une certaine pression, de telle manière qu'il éclate en provoquant un épandage en largeur sous forme de parapluie, la largeur d'épandage étant uniquement fonction de l'angle d'inclinaison de la plaque. Currently, the known slurry spreading devices, mounted at the rear of a slurry tanker, and allowing the spreading of slurry on the field, are designed so as to allow obtaining a large width spreading. Such a result is possible by application of the rules of ballistics, which consist in directing the jet in height by means of a plate inclined relative to the horizontal, and on which said liquid manure jet is propelled under a certain pressure, such that it bursts by causing a spreading in the form of an umbrella, the spreading width being solely a function of the angle of inclination of the plate.

Cependant, ces dispositifs d'épandage connus présentent l'inconvénient de projeter le lisier à une hauteur comprise entre trois et cinq mètres, de sorte que ce dernier offre une prise au vent, qui peut ainsi entraîner les odeurs nauséabondes à plusieurs kilomètres de distance. However, these known spreading devices have the disadvantage of projecting the slurry at a height of between three and five meters, so that the latter offers a windward catch, which can thus cause foul smells several kilometers away.

La présente invention a pour but de pallier cet inconvénient en proposant un dispositif d'épandage pour tonnes à lisier, qui permet, pour une même largeur d'épandage, une hauteur de projection du lisier réduite. The present invention aims to overcome this drawback by proposing a spreading device for slurry tonnes, which allows, for the same spreading width, a reduced slurry projection height.

A cet effet, le dispositif d'épandage pour tonnes à lisier, constitué par une tubulure d'amenée du produit à épandre, et par une palette comportant un bras de support et un déflecteur, cette palette se trouvant sensiblement dans un plan horizontal et le produit à épandre arrivant sensiblement perpendiculairement sur cette palette, qui est, en outre, réglable en inclinaison par rapport à la tubulure d'amenée, caractérisé en ce que le déflecteur est limité, à sa partie tournée vers la citerne, par un rebord canalisant le produit à épandre vers le c8té, ce rebord étant disposé à un angle compris entre 45 et 1350 avec la palette. To this end, the spreading device for slurry tonnes, constituted by a tube for supplying the product to be spread, and by a pallet comprising a support arm and a deflector, this pallet being substantially in a horizontal plane and the product to be spread arriving substantially perpendicularly on this pallet, which is, moreover, adjustable in inclination relative to the supply pipe, characterized in that the deflector is limited, its part facing the tank, by a flange channeling the product to be spread towards c8té, this rim being arranged at an angle between 45 and 1350 with the pallet.

Conformément à une caractéristique de l'invention, le rebord peut dtre complété facultativement par un second rebord disposé à un angle également compris entre 45 et 1350 par rapport au premier rebord.  According to a characteristic of the invention, the flange can be optionally completed by a second flange disposed at an angle also between 45 and 1350 relative to the first flange.

L'invention sera mieux comprise grâce à la description ciaprès qui se rapporte à un mode de réalisation préféré, donné à titre d'exemple non limitatif, et expliqué avec référence aux dessins schématiques annexés, dans lesquels la figure 1 est une vue en élévation latérale d'une tonne à lisier équipée du dispositif d'épandage conforme à l'invention la figure 2 est une vue en coupe, à plus grande échelle, du dispositif d'épandage la figure 3 est une vue en élévation du dispositif, et les figures 4 et 5 sont des vues en plan et en élévation du spectre d'épandage obtenu, respectivement avec un dispositif d'épandage connu, et avec le dispositif conforme à l'invention. The invention will be better understood from the following description which relates to a preferred embodiment, given by way of nonlimiting example, and explained with reference to the appended schematic drawings, in which FIG. 1 is a side elevation view of a slurry tanker equipped with the spreading device according to the invention FIG. 2 is a sectional view, on a larger scale, of the spreading device FIG. 3 is an elevation view of the device, and the figures 4 and 5 are plan and elevation views of the spreading spectrum obtained, respectively with a known spreading device, and with the device according to the invention.

La figure 1 des dessins annexés représente, à titre d'exemple, une tonne à lisier, dont la citerne 1, montée sur des roues 2, et pouvant être reliée à un tracteur au moyen d'un timon 3, est munie d'un groupe de remplissage et de vidange 4 et d'une vanne d'obturation S à la suite de laquelle est monté le dispositif 6 d'épandage de lisier conforme à l'invention. De manière connue, le groupe 4 fonctionne en pompe à vide lors du remplissage de la tonne, et en compresseur lors de sa vidange. Figure 1 of the accompanying drawings shows, by way of example, a slurry tanker, including the tank 1, mounted on wheels 2, and which can be connected to a tractor by means of a drawbar 3, is provided with a filling and emptying group 4 and of a shut-off valve S after which the device 6 for spreading slurry according to the invention is mounted. In known manner, group 4 operates as a vacuum pump when filling the ton, and as a compressor when it is emptied.

Le dispositif 6 d'épandage de lisier, représenté en détail aux figures 2 et 3, est constitué par une tubulure 7 d'amenée du produit à épandre, et par une palette 8 réglable en inclinaison par rapport à la tubulure 7. La palette 8 comporte un déflecteur 9 et un bras de support 10 fixé sur la tubulure 7, et pourvu d'un moyen 11 de réglage de l'inclinaison. La palette 8 se trouve sensiblement dans un plan horizontal et la tubulure 7 amène le produit à épandre sensiblement perpendiculairement sur la palette 8. The slurry spreading device 6, shown in detail in FIGS. 2 and 3, is constituted by a tube 7 for supplying the product to be spread, and by a pallet 8 adjustable in inclination relative to the tube 7. The pallet 8 comprises a deflector 9 and a support arm 10 fixed on the tube 7, and provided with a means 11 for adjusting the inclination. The pallet 8 is located substantially in a horizontal plane and the tubing 7 causes the product to be spread substantially perpendicularly on the pallet 8.

Pour éviter, d'une part, une projection du produit en direction de la citerne et obtenir, d'autre part, une largeur d'épandage importante, la palette 8 est munie, conformément à l'invention, de rebords 12 et éventuellement 13 canalisant ledit produit vers les côtés de la palette 8. Cette dernière peut présenter (voir figures 2 et 3) ou non des bords relevés, qui assurent une certaine régularité dans la répartition du produit à répandre. To avoid, on the one hand, a projection of the product towards the tank and to obtain, on the other hand, a large spreading width, the pallet 8 is provided, in accordance with the invention, with flanges 12 and possibly 13 channeling said product towards the sides of the pallet 8. The latter may or may not have raised edges (see FIGS. 2 and 3), which ensure a certain regularity in the distribution of the product to be spread.

La hauteur du rebord 12 est fonction du diamètre de la tubulure 7, et il a pour r81e, en commun avec le rebord 13, d'éviter les projections sur la citerne 1, et d'assurer une importante largeur d'épandage en correspondance avec une faible hauteur de projection.The height of the rim 12 is a function of the diameter of the tube 7, and it has the role, in common with the rim 13, of avoiding projections onto the tank 1, and of ensuring a large spreading width in correspondence with a low projection height.

Le rebord 12 est disposé à un angle compris entre 450 et 1350 avec la palette 8. Ce rebord 12 porte facultativement un second rebord 13 disposé à un angle également compris entre 450 et 1350 par rapport au rebord 12. The rim 12 is arranged at an angle between 450 and 1350 with the pallet 8. This rim 12 optionally carries a second rim 13 disposed at an angle also between 450 and 1350 relative to the rim 12.

Pour donner au jet une certaine inclinaison de départ, et gagner ainsgen largeur d'épandage, le rebord 13 peut être relevé en 14 sur les cotés de la palette 8 près des bords, en correspondance avec les bords de ladite palette. To give the jet a certain starting tilt, and to gain ainsgen spreading width, the rim 13 can be raised at 14 on the sides of the pallet 8 near the edges, in correspondence with the edges of said pallet.

La figure 4 montre, en plan et en élévation latérale, le spectre d'épandage d'un produit au moyen d'un dispositif connu, pour une vitesse initiale du produit donnée, et la figure 5 montre le spectre obtenu dans des conditions identiques avec le dispositif conforme à l'invention. La comparaison de ces deux spectres démontre très clairement que le chemin à parcourir par le produit pour atteindre la largeur d'épandage maximum est très nettement plus faible dans le cas du dispositif conforme à l'invention, de sorte que dans ce dispositif l'inclinaison de départ- du jet peut être plus faible, donc que l'épandage peut s'effectuer plus au ras du sol, et que la prise au vent est amoindrie. FIG. 4 shows, in plan and in side elevation, the spreading spectrum of a product by means of a known device, for a given initial speed of the product, and FIG. 5 shows the spectrum obtained under identical conditions with the device according to the invention. The comparison of these two spectra shows very clearly that the path to be traveled by the product to reach the maximum spreading width is very much shorter in the case of the device according to the invention, so that in this device the inclination of departure- of the jet can be weaker, therefore that the spreading can be carried out more close to the ground, and that the catch in the wind is lessened.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit et représenté aux dessins annexés. Des modifications restent possibles, notamment du point de vue de la constitution des divers éléments, ou par substitution d'équivalents techniques, sans sortir pour autant du domaine de protection de l'invention.  Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
