Abstract
Description
La présente invention concerne un dispositif de traitement de végétaux, plus particulièrement pour la séparation, dans des produits de récolte, des fruits de débris tels que des branches des plantes, des pierres et autres.The present invention relates to a plant treatment device, more particularly for the separation, in harvest products, of fruits from debris such as branches of plants, stones and the like.
La présente invention est destinée en premier lieu au nettoyage de légumineuses récoltées et, plus particulièrement, des haricots à couper et des haricots princesse, mais, de manière générale, elle peut être utilisée pour le nettoyage d'autres produits de récolte.The present invention is intended primarily for cleaning harvested legumes and, more particularly, cut beans and princess beans, but, generally, it can be used for cleaning other crop products.
On sait que, lors de la récolte mécanisée de légumineuses, divers débris végétaux, principalement constitués de branches des plantes et quelquefois de pierres, se retrouvent dans la récolte.We know that, during the mechanized harvest of legumes, various plant debris, mainly consisting of plant branches and sometimes stones, are found in the harvest.
La séparation industrielle des débris précités se fait de manière classique dans un tambour de criblage rotatif. L'inconvénient de cette technique réside dans le fait que les légumineuses sont endommagées dans un tel tambour de criblage, ce qui entraîne le pourrissement rapide des légumes.The industrial separation of the above-mentioned debris is carried out in a conventional manner in a rotary screening drum. The disadvantage of this technique is that the legumes are damaged in such a screening drum, which causes the vegetables to rot quickly.
La présente invention a pour objet un dispositif qui permet d'effectuer une séparation entre les fruits et les débris, de telle sorte que cet endommagement soit exclu de manière relativement complète ou complète.The present invention relates to a device which makes it possible to carry out a separation between the fruits and the debris, so that this damage is excluded relatively completely or completely.
A cet effet, la présente invention vise un dispositif de traitement de récoltes, plus particulièrement pour la séparation de fruits et des débris présents entre eux, caractérisé en ce qu'il est constitué principalement d'un élément de triage sous la forme d'un crible, dont la face supérieure a une forme en relief.To this end, the present invention relates to a crop processing device, more particularly for the separation of fruit and debris present between them, characterized in that it consists mainly of a sorting element under the form of a screen, the upper face of which has a raised shape.
Du fait que la face supérieure a une forme en relief, il se fait une séparation très rapide dans la mesure où les fruits ne restent présents à la surface du crible que peu de temps et que leur chance de s'endommager est relativement nulle. Les fruits sont basculés sur les arêtes les plus hautes de la surface du crible et tombent à travers le crible.Due to the fact that the upper face has a raised shape, it separates very quickly insofar as the fruits only remain present on the screen surface for a short time and their chance of being damaged is relatively zero. The fruits are tilted on the highest edges of the screen surface and fall through the screen.
L'élément de triage se présente de préférence sous la forme d'une table et mieux encore sous la forme d'une table vibrante.The sorting element is preferably in the form of a table and better still in the form of a vibrating table.
De préférence, la table est constituée d'un certain nombre de lattes disposées de champ et qui se trouvent mutuellement à une certaine distance l'une de l'autre, et dont les arêtes supérieures sont situées à différentes hauteurs, de préférence selon un schéma répétitif. Les lattes utilisées forment entre elles des gorges qui permettent aux fruits allongés de tomber entre elles, tandis que les branches, rarement droites, provenant des plantes, ainsi que des objets relativement volumineux tels que des pierres, restent à la surface du crible.Preferably, the table consists of a number of slats arranged in a field and which lie mutually at a certain distance from each other, and whose upper edges are located at different heights, preferably according to a diagram. repetitive. The slats used form grooves between them which allow the elongated fruits to fall between them, while the branches, rarely straight, coming from plants, as well as relatively bulky objects such as stones, remain on the surface of the screen.
Pour mieux apprécier les caractéristiques selon la présente invention, on décrira ci-dessous, sous forme d'exemples sans caractère limitatif, quelques formes de réalisation préférées sur base des dessins ci-annexés, dans lesquels :
- la Fig. 1 représente un dispositif selon la présente invention,
- la Fig. 2 est une vue selon la flèche F2 dans la Fig. 1, l'élément de triage n'étant pas inclus,
- la Fig. 3 est une vue selon la flèche F3 de la Fig. 2,
- la Fig. 4 est une vue en coupe transversale selon la ligne IV-IV de la Fig. 3, et
- la Fig. 5 est une variante de la partie représentée dans la Fig. 4.
- Fig. 1 represents a device according to the present invention,
- Fig. 2 is a view along arrow F2 in FIG. 1, the sorting element not being included,
- Fig. 3 is a view along arrow F3 in FIG. 2,
- Fig. 4 is a cross-sectional view along line IV-IV of FIG. 3, and
- Fig. 5 is a variant of the part shown in FIG. 4.
Comme illustré dans la Fig. 1, le dispositif 1 selon l'invention est constitué principalement d'un élément de triage 2 sous la forme d'un crible, la face supérieure de cet élément de triage 2 ayant une forme en relief.As illustrated in Fig. 1, the
Comme indiqué dans les Fig. 1 à 4, l'élément de triage 2 est formé en substance d'une table de triage qui est constituée d'un certain nombre d'éléments longitudinaux 3 agencés l'un à côté de l'autre, par exemple des lattes qui sont disposées de champ, de telle sorte que des gorges soient définies entre elles. Les éléments 3 sont montés dans un cadre 5.As shown in Figs. 1 to 4, the
Afin de former le relief précité, les éléments 3 sont réalisés et/ou placés de telle sorte qu'ils définissent diverses arêtes supérieures 6-8 qui sont situées à différentes hauteurs. La hauteur des arêtes supérieures varie de préférence selon un schéma répétitif. Plus spécialement, on préfère utiliser un schéma tel qu'indiqué dans la Fig. 4. Dans celle-ci, les arêtes supérieures 6 les plus hautes se répètent tous les quatre éléments 3. Au centre, entre les éléments 3 avec les arêtes supérieures précitées 6 se trouvent des éléments 3 comportant une arête supérieure 7 un peu plus basse. Par ailleurs, entre les éléments 3 ayant une arête supérieure 6 ou 7 se trouve un élément 3 avec une arête supérieure 8, qui est disposée plus bas que les arêtes supérieures 6 et 7.In order to form the abovementioned relief, the
Comme indiqué dans la Fig. 3, les éléments 3 divergent un peu les uns vis-à-vis des autres dans la direction A dans laquelle les produits à traiter sont normalement déplacés par-dessus de l'élément de triage 2. A cet effet, on évitera qu'il y ait des obstructions, par exemple formées par des pierres, entre deux éléments élevés 3.As shown in Fig. 3, the
L'écart moyen entre les éléments 3, en d'autres termes, la largeur moyenne des gorges 4, est de préférence de 1 à 3 cm. La différence de hauteur la plus grande entre les arêtes supérieures des éléments 3, dans ce cas les arêtes supérieures 6 et 8, est de préférence de 1 à 5 cm.The average difference between the
L'élément de triage 2 est de préférence conçu sous la forme d'une table vibrante et est dans ce cas également couplé à un mécanisme de vibration 9 ou fixé à cet effet à une table vibrante classique.The
Comme montré schématiquement dans la Fig. 1, le dispositif 1 peut être équipé de moyens d'alimentation et d'évacuation, respectivement, pour amener les produits à séparer et évacuer respectivement les produits séparés.As shown schematically in FIG. 1, the
Afin de recueillir les fruits ou légumes 10 en dessous de l'élément de triage 3, il peut être prévu en position inférieure un élément collecteur 11 pourvu d'un système d'évacuation 12 le long duquel les fruits 10 peuvent être évacués. Mais il est manifeste que, selon une variante, cet élément collecteur 11 peut être supprimé, les fruits tombant alors du dispositif 1, par exemple, dans une caisse ou analogue placée en dessous.In order to collect the fruits or
L'alimentation de produits à séparer peut se faire à l'aide d'une surface inclinée 13, d'une bande transporteuse, etc.The product to be separated can be fed using an
L'évacuation des débris, à savoir les déchets 14 qui sont constitués principalement de branches, de feuilles et de pierres, peut également se faire via une surface inclinée 15, une bande transporteuse, etc., ces déchets étant évacués vers un espace collecteur.The evacuation of debris, namely the
L'élément de triage 2 est monté avec sa face supérieure inclinée et/ou est soumis à une vibration de telle sorte que les produits se déplacent du côté d'alimentation au côté d'évacuation.The
Afin d'améliorer la stabilité, les éléments 3 peuvent être fixés en position inférieure à un profilé transversal 16.In order to improve stability, the
Le fonctionnement et l'usage du dispositif 1 peuvent se déduire simplement de la Fig. 1 et seront expliqués encore plus en détail dans la Fig. 4. Les produits à séparer, à savoir les fruits 10, et les déchets 14 présents entre eux, sont amenés sur l'élément de triage 2, par exemple, via le plan incliné. Les fruits ou légumes 10, dans l'exemple illustré des haricots allongés, tombent à travers l'élément de triage 2 jouant le rôle de crible, tandis que les déchets 14 restent présents sur l'élément de triage 2. Du fait que la face supérieure de l'élément de triage 2 a une forme en relief et, en particulier, du fait qu'elle est formée d'éléments hauts et bas 3 disposés en alternance, il est impossible que les fruits 10 restent présents sur l'élément de triage 2. Comme indiqué dans la Fig. 4, un haricot ou autre végétal, qui est présent sur l'arête la plus haute 6, est forcé de basculer parce que l'arête voisine 7 se trouve plus bas, si bien que le haricot exécutera un mouvement de basculement et de rotation et tombera à travers la gorge concernée 4 de l'élément de triage 2.The operation and use of the
Comme indiqué dans la variante de la Fig. 5, les gorges 4 peuvent diverger vers le bas, par exemple, parce que les éléments 3 sont fixés de manière divergente dans le cadre 5, si bien que des obstructions entre les éléments 3 sont exclues.As indicated in the variant of FIG. 5, the
Il est clair que, selon une variante, on peut prévoir d'autres moyens d'alimentation et d'évacuation. C'est ainsi qu'il peut être prévu, par exemple, un mécanisme susceptible de permettre qu'une quantité déterminée de produits à nettoyer soit disposée sur l'élément de triage 2, y reste présente un temps déterminé tandis qu'un mouvement de vibration est effectué, et qu'ensuite les débris subsistant derrière l'élément de triage 2 soient séparés en faisant basculer l'élément de triage 2.It is clear that, according to a variant, other means of supply and evacuation can be provided. Thus it can be provided, for example, a mechanism capable of allowing a determined quantity of products to be cleaned to be placed on the
Il est à noter que, lors d'un procédé en continu, les produits à traiter sont déplacés de préférence dans la direction précitée A, à savoir dans la direction des éléments précités au-dessus de l'élément de triage 2. Mais, il n'est pas exclu de déplacer ces produits dans la direction transversale à cette direction.It should be noted that, during a continuous process, the products to be treated are preferably moved in the above-mentioned direction A, namely in the direction of the above-mentioned elements above the
L'ensemble est réalisé de préférence en acier.The assembly is preferably made of steel.
La présente invention n'est en aucune manière limitée aux formes de réalisation décrites à titre d'exemples dans la présente demande et reproduites dans les figures, mais un tel dispositif de traitement de végétaux peut être réalisé dans diverses formes et dimensions sans sortir du cadre de l'invention tel que défini dans les revendications ci-annexées.The present invention is in no way limited to the embodiments described by way of examples in the present application and reproduced in the figures, but such a plant treatment device can be produced in various forms and dimensions without departing from the scope of the invention as defined in the appended claims.
