Abstract

The present addition relates to agro-foodstuff adaptations (used in canneries, handling raw or cooked fruits or vegetables, grapes or marc, etc.) of the screw with a trough having a flexible base made from extra-strong polyester canvas. It comprises, in its widened bottom part (hopper) two semi-rigid deflectors, of which one 2a is positioned to enable the vegetables to slide on the opposite rising side of the screw so that they are not wedged between the edge of the screw and the canvas. The equipment will be adapted as a function of each particular case: back-geared motor at the head in order to obtain maximum lowering, boom (ramp) for spraying water over the run, etc.

Description

La présente addition concerne les utilisations agro alimentaires de la vis d'Archimede avec auget à fond souple principalement en fonctiorr de manutention dans les conserveries, le transfert de raisin, de marc, etc.... The present addition relates to the agro-food uses of the Archimede screw with a bucket with a flexible bottom mainly in function of handling in canneries, transfer of grapes, marc, etc.

Les qualités propres de la vis d'Archimède de diamètre moyen, à rotation lente, équipée d'un auget souple avec bache polyester extra forte légèrement tendue sont maintenant reconnues. Elle permet le transfert de pois cuits (légume fragile entre tous sans les détériorer. La conception de tension de la bache munie bi latéralement de fourreaux dans lesquels passe un tube supporté par des tendeurs élastiques ou des ressorts légèrement tendus et judicieu nament tep3Ytis, lui confèrent une bonne tenue dans le temps avec des produits aqueux. La version agro alimentaire de la vis à fond souple mettra en oeuvre des matériau': bien spécifiques : inox et bache polyester enduite de PVC ali-. The inherent qualities of the Archimedes screw of medium diameter, with slow rotation, equipped with a flexible bucket with slightly strong extra strong polyester tarpaulin are now recognized. It allows the transfer of cooked peas (fragile vegetable among all without damaging them. The tension design of the tarpaulin provided bi laterally with sheaths in which passes a tube supported by elastic turnbuckles or slightly stretched springs and judiciously tep3Ytis, give it good resistance over time with aqueous products The agro-food version of the screw with flexible bottom will use materials: very specific: stainless steel and polyester tarpaulin coated with PVC ali-.

mentaire (de couleur blanche ou crème de préférence).mentally (preferably white or cream in color).

La trémie de réception devra être conçue en fonction de-chaque cas particulier. Un élargissement du chassis permettant la pose de déflecteurs en matériau semi rigide. Au fond de la trémie un déflecteur réglable devra diriger les légumes déversés du coté du sens de rotation remontant de la vis, de manière à en éviter la détérioration qui risquerait de ce produire par coincement entre la bache et la vis, si les légumes étaient dirigés de ltau tre coté. The receiving hopper must be designed according to each particular case. A widening of the chassis allowing the installation of deflectors in semi rigid material. At the bottom of the hopper an adjustable deflector must direct the spilled vegetables on the side of the direction of rotation going up the screw, so as to avoid deterioration which could risk this product by jamming between the tarpaulin and the screw, if the vegetables were directed from the side.

D'autre part, pour éviter le collage de certains légumes après les spires de la vis, une projection d'eau par pulvérisation ou en filet pourra être prévue. On the other hand, to avoid sticking of certain vegetables after the turns of the screw, a projection of water by spraying or with a net may be provided.

Pour garder le caractère de surbaissement indispensable dans des cas bien particuliers, le moto réducteur d'entrainement de la vis devra être positionné en tête. Le réducteur à vis et arbre creux permettra moins d'encombrement en longueur. To keep the essential lowering character in very specific cases, the gear motor of the screw drive must be positioned at the head. The screw and hollow shaft reducer will allow less overall length.

L'invention sera mieux comprise à la lecture de la description suivante , mise en relation avec les dessins joints qui représentent schématiquement un exemple de réalisation. The invention will be better understood on reading the following description, linked to the accompanying drawings which schematically represent an exemplary embodiment.

La figure 1 représente en perspective cavalière la vis avec auget à fond souple asec son chassis élargi (1) en partie basse pour en faciliter le chargement, et surbaissé également pour permettre l'approche de bennes vendangeuses en extrémité. L'électro réducteur d'entrainement de la vis sera po sitionné à l'autre extrémité (haute) ~ pour ne pas encombrer l'entrée. On remarquera les 2 déflecteurs (trémie) (2) bi latéraux en plastique < PVC) semi rigide. A noter que l'équipement de la vis peut être adapté à chque cas particulier : encoches dans la vis pour le nettoyage des carottes, adaptaticn d' une rampe de pulvérisation pour le transfert de pomnes de terre coupées en rondelles fines, etc.... Figure 1 shows in perspective the screw with a flexible bottom bucket asec its enlarged frame (1) in the lower part to facilitate loading, and also lowered to allow the approach of grape harvesting bodies at the end. The screw drive electro-reducer will be positioned at the other end (high) ~ so as not to clutter the inlet. Note the 2 semi-rigid plastic deflectors (hopper) (2) bi side plastic <PVC). Note that the equipment of the screw can be adapted to each particular case: notches in the screw for cleaning the carrots, adaptation of a sprayer boom for the transfer of potatoes cut into thin rings, etc ... .

La Figure 2 représente schématiquement une vue en coupe de l'extrémité basse (trémie) avec les longerons (1), les déflecteurs(2a) et(2b) en plastique semi rigide, la vis (3J et la bache polyester qualité alimentaire (4) laquelle est légèrement tendue par les ressorts t5J et maintenue par 2 tubes longitudinaux (6) emprisonnés dans les fourreaux bi latéraux de la bache, lesquels sont thermo soudés (meilleure solidité qu'une couture). Ceci étant une description sommaire en rappel du Brevet principal. Figure 2 shows schematically a sectional view of the lower end (hopper) with the side members (1), the deflectors (2a) and (2b) in semi-rigid plastic, the screw (3J and the food-grade polyester cover (4 ) which is slightly stretched by the springs t5J and held by 2 longitudinal tubes (6) trapped in the bi-lateral sheaths of the tarpaulin, which are heat welded (better strength than a seam). This being a brief description as a reminder of the Patent main.

Revenant aux déflecteurs, on remarquera que celui de gauche (2a) est positionné en surélévation, la vis tournant lentement (entre 20 et 80 tours minute selon les cas) dans le sens opposé à celui des aiguilles d'une montre, les légumes à transférer glissant sur le déflecteur (2a) ne seront pas détériorés par le coincement entre l'aréte de la vis et la bache comme s'ils étaient dirigés ccté opposé.  Returning to the deflectors, it will be noted that the left one (2a) is positioned in raised position, the screw turning slowly (between 20 and 80 revolutions per minute depending on the case) in the opposite direction to that of clockwise, the vegetables to be transferred sliding on the deflector (2a) will not be damaged by the wedging between the edge of the screw and the cover as if they were directed opposite side.
