Abstract
Description
La présente invention concerne un dispositif de levage, pour sacs de 50 kg, destiné à être fixé sur des épandeurs d'engrais. The present invention relates to a lifting device, for 50 kg bags, intended to be fixed on fertilizer spreaders.
Les épandeurs d'engrais sont un des matériels des plus courants dans les exploitations agricoles. Ils sont équipés d'une trémie pouvant contenir plusieurs centaines de kilogramnes de produit à épandre. One of the most common materials on farms is fertilizer spreaders. They are equipped with a hopper which can contain several hundred kilograms of product to be spread.
L'alimentation de ces épandeurs par des sacs de 50 kg qui constituent le mode de conditionnement le plus courant est dans 1 état actuel de la technique une opération manuelle fastidieuse. Il existe bien plusieurs modèles d'alimentation (objet des brevets FR 2.254.933 et 2.433.277), mais ces procédés reposent sur l'utilisation d'une flèche hydraulique articulée sur le tracteur ou sur l'épandeur. Cependant, cette flèche est relativement longue et nécessite une force de levage importante. D'autre part, ce procédé ne peut s'appliquer qu'aux sacs d'une contenance de mê- me ordre de grandeur que la trémie et non aux sacs de 50 kg. En effet, le moyen d'accrochage du sac à la flèche est un lien à noeud coulant, ce qui en rend son utilisation impossible pour les sacs de 50 kg.De plus, les coûts d'ensachage sont plus élevés du fait de la nécessaire résistance des sacs. Cette formule présente enfin l'inconvénient de manquer de souplesse car les quantités de produit à épandre sont difficilement fractionnables en quantités différentes de la contenance du sac. Feeding these spreaders with 50 kg bags which are the most common mode of packaging is a tedious manual operation in the current state of the art. There are indeed several feeding models (subject of patents FR 2,254,933 and 2,433,277), but these methods are based on the use of a hydraulic boom articulated on the tractor or on the spreader. However, this boom is relatively long and requires a large lifting force. On the other hand, this process can only be applied to bags with a capacity of the same order of magnitude as the hopper and not to 50 kg bags. Indeed, the means of hanging the bag on the arrow is a slip knot link, which makes its use impossible for 50 kg bags. In addition, the bagging costs are higher because of the necessary resistance of the bags. This formula finally has the drawback of lacking flexibility since the quantities of product to be spread are difficult to split into quantities different from the capacity of the bag.
La présente invention permet de réduire considérablement la manutention des sacs lors du remplissage de la trémie, tout en utilisant des sacs de 50 kg qui présentent l'avantage de moduler aisément la quantité à épandre. The present invention makes it possible to considerably reduce the handling of the bags when filling the hopper, while using 50 kg bags which have the advantage of easily modulating the quantity to be spread.
Il s 'agit d'un dispositif de levage qui soulève les sacs, préalablement déposés sur un plateau et les amène au-dessus de l'épandeur
La description qui suit pourra mieux faire comprendre, en regard des schémas annexés à titre d'exemple, comment l'invention peut être réalisée.It is a lifting device which lifts the bags, previously placed on a tray and brings them above the spreader
The following description will make it easier to understand, with reference to the diagrams annexed by way of example, how the invention can be implemented.
Le dispositif de levage est destiné à être accouplé à la trémie (1) d'un épandeur. Il comprend un bâti composé de deux montants verticaux (2) dont les extrémités inférieures sont prolongées par un socle (9). The lifting device is intended to be coupled to the hopper (1) of a spreader. It comprises a frame made up of two vertical uprights (2), the lower ends of which are extended by a base (9).
Autour d'un axe (3) situé sur les montants verticaux (2) vient pivoter un ensemble mobile comprenant deux bras (4). Des trous (16) et (17) régulièrement espacés sur les montants verticaux (2) et sur les bras (4) permettent de les articuler en différents endroits. Lesdits bras (4) sont reliés à leur extrémité par une barre transversale (20) mieux visible en fig. 3, sur laquelle est monté pivotant un plateau (6) destiné à recevoir les sacs (7) à soulever. L'ensemble mobile est actionné par un verin hydraulique (5) alimenté au moyen d'un flexible (19) par le circuit hydraulique du tracteur auquel est attelé l'épandeur. Ledit verin est articulé à sa base autour d'un axe (21) situé sur un des socles (9) et à son autre extrémité autour d'un axe (22) situé sur un des bras (4).La disposition desdits axes (21) et (22) est réglable grâce à des jeux de trous (14) et (15) régulièrement espacés sur le socle (9) et le bras (4) auxquels est relié le verin hydraulique (5). Around a axis (3) located on the vertical uprights (2) pivots a mobile assembly comprising two arms (4). Holes (16) and (17) regularly spaced on the vertical uprights (2) and on the arms (4) allow them to be articulated in different places. Said arms (4) are connected at their end by a transverse bar (20) better visible in FIG. 3, on which is pivotally mounted a plate (6) intended to receive the bags (7) to be lifted. The mobile assembly is actuated by a hydraulic cylinder (5) supplied by means of a hose (19) by the hydraulic circuit of the tractor to which the spreader is coupled. Said cylinder is articulated at its base around an axis (21) located on one of the bases (9) and at its other end around an axis (22) located on one of the arms (4). The arrangement of said axes ( 21) and (22) is adjustable thanks to sets of holes (14) and (15) regularly spaced on the base (9) and the arm (4) to which the hydraulic cylinder (5) is connected.
En position basse, illustrée en fig. 1, l'utilisateur dispose sur le plateau (6) les sacs (7) à soulever. Lorsque le verin hydraulique (5), alimenté par le circuit hydraulique du tracteur, se déploie, il provoque un mouvement rotatif de l'ensemble mobile autour de l'axe (3) et un mouvement ascendant du plateau (6). In the low position, illustrated in fig. 1, the user has the bags (7) to be lifted on the tray (6). When the hydraulic cylinder (5), supplied by the hydraulic circuit of the tractor, deploys, it causes a rotary movement of the mobile assembly around the axis (3) and an upward movement of the plate (6).
Dans son mouvement ascendant, le plateau (6) est maintenu sensiblement horizontal grâce à un cable (8) relié d'une part à un des socles (9) et d'autre part, par une chaînette (10), au plateau, côté opposé au tracteur. Le cable (8) est guidé par deux poulies (11) et (12) montées sur un bras (4). L'une, la (12) est située à l'extrémité du bras (4) côté plateau (6), l'autre, la' (11) peut être montée en différents endroits sur ledit bras (4) grâce à des logements (13) pouvant recevoir sélectivement l'axe de la poulie (11). In its upward movement, the plate (6) is kept substantially horizontal thanks to a cable (8) connected on the one hand to one of the bases (9) and on the other hand, by a chain (10), to the plate, side opposite the tractor. The cable (8) is guided by two pulleys (11) and (12) mounted on an arm (4). One, the (12) is located at the end of the arm (4) on the plate side (6), the other, the '(11) can be mounted in different places on said arm (4) thanks to housings (13) can selectively receive the axis of the pulley (11).
En position haute (fig. 2), les sacs (7) sont amenés au-dessus de la trémie (1) et il suffit alors de les percer par un objet tranchant pour que le produit à épandre s'écoule dans la trémie (1). In the high position (fig. 2), the bags (7) are brought above the hopper (1) and it suffices to pierce them with a sharp object so that the product to be spread flows into the hopper (1 ).
Les montants métalliques du bâti sont conçus de façon à ce qu 'ils puissent coulisser les ùns dans les autres (23), (24), (25), ceci de fa çon à ce que le dispositif de levage soit adaptable à un grand nombre de modèles d'épandeurs. The metal uprights of the frame are designed so that they can slide the ends in the others (23), (24), (25), this so that the lifting device is adaptable to a large number of spreader models.
L'invention peut s'appliquer à tout genre d'épandeurs d'engrais ou autres produits pulvérulents. Des modifications peuvent être apportées au mode de réalisation précédemment décrit par substitution de moyens techniques équivalents sans sortir pour autant de la présente invention. The invention can be applied to any kind of spreader of fertilizers or other pulverulent products. Modifications can be made to the embodiment described above by substitution of equivalent technical means without departing from the present invention.
