Abstract

The trap-door for a motor vehicle transports sand or powder. It is situated above a tunnel which contains a helical screw feed (2). The trap-door comprises flaps (5) hinged to a longitudinal (7) positioned directly above the screw feed which is suspended by vertical shafts (9) and which can be raised or lowered by hydraulic or pneumatic rams from the exterior of the lorry. The flaps are guided by longitudinally spaced frames (3) which are trapezoidal in cross-section, so that when lowered the flaps touch the sides (10) preventing material from passing into the screw feed.

Description

La présente invention concerne spécialement des perfectionnements importants à apporter aux camions de transports ou trains concernant le déchargement rapide des produits en vrac,tels que: farines,plàtre,ciments,granulés par exenlple: soit en entier,soit par fractions de trémies séparées contenant des produits différents.The present invention relates in particular to important improvements to be made to transport trucks or trains concerning the rapid unloading of bulk products, such as: flour, plaster, cements, granules for example: either whole or by fractions of separate hoppers containing different products.

I1 suffit pour celà que chaque camion soit séparé inté rieurement,longitudin-alement ou perpendiculairement, en deux ou plusieurs parties constituant des trémies séparées. It is sufficient for this that each truck is separated internally, longitudinally or perpendicularly, into two or more parts constituting separate hoppers.

Pour la vidange,il est donc utile de pratiquer à la base du camion ou container sur toute la longueur intérieure,une gouttière (I) dans laquelle tournera une vis hélicoTdale (2) d'entrainement ayant pour but dd récupérer le produit à la sortie. For emptying, it is therefore useful to practice at the base of the truck or container over the entire interior length, a gutter (I) in which will rotate a helical screw (2) for training intended to recover the product at the outlet .

Les trappes (5) pourront se fermer en descendant,obliquement ou verticalement,et posséder des couteaux dans le but de casser la voûte des produits ayant tendance de s'agglutiner par leurs poids. The hatches (5) can close down, obliquely or vertically, and have knives in order to break the roof of the products which tend to clump together by their weight.

La déformation des trappes (5) due au poids du produit se trouve supprimé gracie à la poutre porteuse ou charpente (7) supportant les efforts de flexion. Les trappes sont maintenues ouvertes par des supports (3) fixés sur la partie supérieure de I'auge (I) ,elles sont guidées pour la fermeture et l'ouverture par deux doigts cintrés (4) fixés à leurs extrémités et sur les pentes intérieures (IO) du container. L'étanchéité des trappes est réalisée grace au profil de l'auge(I) adapté au système. Ces trappes sont commandées hydrauliquement par vérins ou autre mécanisme approprié. The deformation of the hatches (5) due to the weight of the product is eliminated thanks to the supporting beam or frame (7) supporting the bending forces. The hatches are kept open by supports (3) fixed on the upper part of the gauge (I), they are guided for closing and opening by two curved fingers (4) fixed at their ends and on the inner slopes (IO) from the container. The hatches are sealed using the trough profile (I) adapted to the system. These hatches are hydraulically controlled by jacks or other suitable mechanism.

En 'ariante,pour les grands et petits transports de ma tières en vrac,unique ou différents, les trappes obstruant l'ouverture des trémis,peuvent autre rotatives et manoeuvrées manuellement. In 'ariante, for large and small transport of my bulk materials, single or different, the hatches obstructing the opening of the hoppers, can other rotary and manually operated.

Les dessins représentés et décrits,ne sont donnés ici qu'S titre schEmatique,indicatif non limitatif et sont sujets à de nombreuses variantes de réalisations et d'applications comme produit Industriel nouveau. The drawings shown and described are given here only as a schematic, non-limiting indication and are subject to numerous variants of embodiments and applications as a new industrial product.
