Abstract

The present invention relates to a machine 1 with a cutting screw including a series of cutting elements 6 which are arranged along the helical edge of the screw 3 itself and which interact with mating cutting elements 4 which are mounted on the internal wall of a truck for unloading fodder from a silo. The particular shape of the mating cutting elements 4 makes it possible, during rotation of the screw, and thus the rotation of the cutting elements 6, to chop the filamentary materials contained in the truck easily. In this way, the machine can provide optimum production capability, the resulting product being chopped very rapidly and better than the product obtained by applying a known technique.

Description

La présente Invention se rapporte à une machine à vis tranchante adaptée pour hacher des matières filamenteuses et coopérer avec des moyens de coupe profilés de taçon particulière et agencés le long de la surface piane Inférieure d'un chariot ou analogue dans lequel la machine à vis elle-meme est montée. The present invention relates to a sharp screw machine suitable for chopping filamentary materials and cooperating with profiled cutting means of a particular brickwork and arranged along the lower planar surface of a carriage or the like in which the screw machine - even went up.

Dans la technique utilisée actuellement, on connalt diverses machines ou chariots dans lesquels sont installés Intérieurement des vis hélicoïdales dont le bord hélicoidol est continu ou découpé en plusleurs secteurs, lesquels sont montés autour d'un arbre rotatif disposés horizontalement. Ces machines ou chariots connus sont adaptés pour recevolr des matières filamenteuses, provenant de silos, telles que des herbes comestibles pour l'alimentation du bétail et ensuite, hacher ces matières elles-memes en vue de les mettre en condition pour être utilisées immédiotement.A cette fin, le bord hélicoïdal de la vis, ou des secteurs de vis, est pourvu d'éléments de coupe permettant un meilleur hachage des rentières. Les éléments de coupe peuvent être de différents types mais, cependant. on a trouvé que leur capacité de coupe est limitée et ne permet pas d'effectuer un hachage rapide du fourrage. In the technique currently used, various machines or carts are known in which helical screws are internally installed, the helical edge of which is continuous or cut into several sectors, which are mounted around a rotary shaft arranged horizontally. These known machines or trolleys are suitable for receiving filamentary materials, coming from silos, such as edible herbs for livestock feed and then chopping these materials themselves in order to put them in condition for immediate use. To this end, the helical edge of the screw, or of the screw sectors, is provided with cutting elements allowing better chopping of the annuities. The cutting elements can be of different types, however. it has been found that their cutting capacity is limited and does not allow rapid chopping of the forage.

Le but de la présente invention est de fournir une plus grande rapidité et une meilleure qualité de hachage à ce type de machine en Jumelant la vis avec des moyens de contre-coupe adaptés afin que cette machine puisse atteindre une capacité optimale de production et que le produit résultant soit de meilleure qualité du fait de son hachage parfait. The object of the present invention is to provide greater speed and better quality of chopping to this type of machine by combining the screw with suitable counter-cutting means so that this machine can reach an optimal production capacity and that the resulting product is of better quality due to its perfect chopping.

En conséquence, la présente invention se rapporte à une machine à vis tranchante, adaptée pour hacher des matières filamenteuses ensilées, du type à spirale continue, ou constituée de secteurs, chacun de ces secteurs étant pourvu d'une série d'éléments de coupe situés le long de son bord hélicoïdal, ces éléments de coupe étant constitués de plaquettes ayant une forme circulaire, ou de secteur circulaire, cette machine à vis étant remarquable par le fait qu'elle est jumelée avec des éléments de contrecoupe qui sont disposés sur la parol Intérleure du chariot ou similaire dans lequel elle est montée, ces éléments de contre-coupe étant constitués par des lamelles en forme de "U' dont les côtés, ou ailes, ont leurs bords arrondis ou chanfreinés dans le sens d'avancement de la vis elle-même. Consequently, the present invention relates to a cutting screw machine, suitable for chopping silage filamentary materials, of the continuous spiral type, or made up of sectors, each of these sectors being provided with a series of cutting elements located along its helical edge, these cutting elements being made up of inserts having a circular shape, or of circular sector, this screw machine being remarkable in that it is twinned with counter-cutting elements which are arranged on the floor Interior of the carriage or the like in which it is mounted, these counter-cutting elements being constituted by lamellae in the shape of a "U" whose sides, or wings, have their edges rounded or chamfered in the direction of advance of the screw herself.

De manière plus précise, ces éléments de contre-coupe sont disposés sur une file, I'un après l'autre, de préférence le long d'une bande de la paroi Intérieure du chariot, cette bande étant déterminée en fonction de l'avancement en rotation de la vis. More precisely, these counter-cutting elements are arranged in a line, one after the other, preferably along a strip of the interior wall of the carriage, this strip being determined according to the progress in rotation of the screw.

De plus, ces éléments de contre-coupe sont fixés sur la paroi intérieure du véhicule par l'intermédiaire de plaques d'arrêt retenues au moyen de fixations classiques. In addition, these counter-cutting elements are fixed to the interior wall of the vehicle by means of stop plates retained by means of conventional fasteners.

La présente Invention sera mieux comprise de la description suivante d'un mode de réalisation donné à titre d'exemple non limitatif et représenté dans les dessins ci-joints dans lesquels:
- la figure 1 est une vue schématique en perspective d'une partie avant d'une machine à vis et d'éléments de contre-coupe, conformément à la présente invention;
- la figure 2 est une vue de face de ia machine à vis et d'une paroi de fond d'un chariot sur laquelle les éléments de confre-coupe conformes à la présente invention, sont montés; ef
- la figure 3 représenfe en détail, un élément de confre-coupe, ou contrelame, conforme à l'invention, et agencé pour coopérer avec un élément de coupe, ou lame, de la vis.The present invention will be better understood from the following description of an embodiment given by way of nonlimiting example and represented in the attached drawings in which:
- Figure 1 is a schematic perspective view of a front part of a screw machine and counter-cutting elements, in accordance with the present invention;
- Figure 2 is a front view of ia screw machine and a bottom wall of a carriage on which the counter-cutting elements according to the present invention are mounted; ef
- Figure 3 shows in detail, a cut-off element, or counterblade, according to the invention, and arranged to cooperate with a cutting element, or blade, of the screw.

Dans ces figures, la référence I indique, dans son ensemble, une machine à vis qui peut être constifuée sous forme d'une vis continue ou, comme montré, sous forme d'une vis constituée de secteurs hélicoïdaux 2, montés sur un arbre horizontal 3, conformément à certains types de vis connus dans la technique, et placés à l'intérieur de chariofs à désensiler de façon à coopérer avec la paroi inférieure de ce dernier en vue de hacher du fourrage ou d'autre matières filamenteuses pour l'alimentation du béfail.  In these figures, the reference I indicates, as a whole, a screw machine which can be made up in the form of a continuous screw or, as shown, in the form of a screw made up of helical sectors 2, mounted on a horizontal shaft 3, in accordance with certain types of screw known in the art, and placed inside desriiler to desensitize so as to cooperate with the lower wall of the latter in order to chop fodder or other filamentary materials for food befail.

A cefte fin, conformément à la présente invention, des éléments de contre-coupe 4 sont disposés les uns à côté des autres sur la paroi intérieure 5 d'un chariof à désensiler et de façon à coopérer avec les éléments de coupe 6 correspondants de la vis hélicoïdale. To this end, in accordance with the present invention, counter-cutting elements 4 are arranged one next to the other on the inner wall 5 of a desensitive chariof and so as to cooperate with the corresponding cutting elements 6 of the helical screw.

De manière plus précise, les éléments de contre-coupe 4 sont écartés, de l'un à l'autre, de façon que chaque élément de coupe 6 de la vis puisse passer à l'intérieur d'un élément de contre-coupe lorsque cette vis est mise en rotation d'avancement. De tels éléments de contre-coupe, ou contrelames, 4 sont obtenus en partant d'une lamelle dont les bords sont pliés de manière à constituer deux ailes verticales qui donnent à ces éléments de contre-coupe une conformation analogue à un U.  More specifically, the counter-cutting elements 4 are spaced from one to the other, so that each cutting element 6 of the screw can pass inside a counter-cutting element when this screw is rotated forward. Such counter-cutting elements, or counterblades, 4 are obtained starting from a strip whose edges are folded so as to constitute two vertical wings which give these counter-cutting elements a conformation similar to a U.

En pratique, un élément de contre-coupe 4 correspond à chaque élément de coupe 6 de manière à obtenir une action parfaite de hachage sur toute la longueur du chariot. A cefte fin, les éléments de contre-coupe, ou contrelames, 4 sont disposés les uns à côté des autres, de préférence le long d'une bande de la paroi intérieure du chariot, cette bande étant déterminée en fonction de l'avancement rotatif de la vis et, plus précisément, par la première zone d'approche dans loquelle les lames 6 du transporteur à vis approchent la paroi Intérieure 5 elle-même. In practice, a counter-cutting element 4 corresponds to each cutting element 6 so as to obtain a perfect chopping action over the entire length of the carriage. At this end, the counter-cutting elements, or counterblades, 4 are arranged one beside the other, preferably along a strip of the inner wall of the carriage, this strip being determined as a function of the rotary advance. of the screw and, more precisely, by the first approach zone in which the blades 6 of the screw conveyor approach the Inner wall 5 itself.

En vue de faciliter, et ainsi de soulager, l'action de hachage des produits, les côtés, ou ailes, 7 des éléments de contre-coupe ont sieurs bords arrondis ou chanfreinés afin de permettre une meilleure interaction des éléments de coupe. In order to facilitate, and thus relieve, the chopping action of the products, the sides, or wings, 7 of the counter-cutting elements have their rounded or chamfered edges in order to allow better interaction of the cutting elements.

Chaque élément de contre-coupe, ou contrelome, 4 est monté sur la paroi Intérieure 5 du véhicule par l'intermédlaire d'une ploque d'arrêt 8 qui est retenue par des moyens de fixation classiques. Each counter-cutting element, or contrelome, 4 is mounted on the interior wall 5 of the vehicle by the intermediary of a stop plate 8 which is retained by conventional fixing means.

L'interpénétratlon entre les éléments de coupe 6 de la vis, qui sont
Inclinés, et les éléments de contre-coupe 4, ou contrelames, permet à la machine d'atteindre une capacité optimale de production, le produit résultant étant haché beaucoup plus rapidement que celui qui étalt haché en utilisant la technique connue. Interpenetration between the cutting elements 6 of the screw, which are
Inclined, and the counter-cutting elements 4, or counterblades, allows the machine to reach an optimal production capacity, the resulting product being chopped much faster than that which was chopped using the known technique.
