Abstract
Description
La présente invention se rapporte à un dispositif servant à broyer des matériaux tels que du bois, de l'herbe, des feuillages, de la matière plastique, du papier, du carton ou analogues, formé d'un jeu de couteaux avec un broyeur préliminaire et un jeu de couteaux en étoile. The present invention relates to a device for grinding materials such as wood, grass, foliage, plastic, paper, cardboard or the like, formed of a set of knives with a preliminary grinder and a set of star knives.
Les dispositifs de ce type qui sont déjà connus, présentent l'inconvénient que plus particulièrement dans le cas de matériaux légers, il n'y a pas de prise en charge des produits coupés par le broyeur préliminaire et que d'autre pa*7n il y a toujours un risque que les produits coupés se bloquent.-
La présente invention a donc pour but de créer un dispositif du type précité à l'aide duquel les produits coupés peuvent autre broyés rapidement et régulièrement.Devices of this type which are already known, have the disadvantage that more particularly in the case of light materials, there is no handling of the products cut by the preliminary grinder and that other pa * 7n il there is always a risk that the cut products may become blocked.
The present invention therefore aims to create a device of the aforementioned type with the help of which the cut products can be further ground quickly and regularly.
Conformément à l'invention, ce but est obtenu par le fait que les extrémités des couteaux du broyeur préliminaire sont disposès, dans le sens de l'axe longitudinal, en étant décalées réciproquement suivant un angle r de 5 à 300. According to the invention, this object is obtained by the fact that the ends of the knives of the preliminary mill are arranged, in the direction of the longitudinal axis, being mutually offset at an angle r of 5 to 300.
De cette façon, on obtient que la prise en charge des produits à couper soit indépendante de la nature de chaque produit. In this way, it is obtained that the handling of the products to be cut is independent of the nature of each product.
Pour broyer finement les produits à couper, un mode de réalisation avantageux de l'invention prévoit que le couteau plat situé au niveau supérieur du jeu de couteaux en étoile est recourbé vers le haut. To finely grind the products to be cut, an advantageous embodiment of the invention provides that the flat knife situated at the upper level of the set of star knives is bent upwards.
Suivant une autre configuration avantageuse de l'invention, les extrémités du couteau plat du jeu de couteaux en étoile présentent un angled2oMbre h de manière à éviter tout blocage ou coincement des produits à couper, plus particulierement dans le cas du bois. According to another advantageous configuration of the invention, the ends of the flat knife of the set of star knives have an angled2oMbre h so as to avoid any blocking or jamming of the products to be cut, more particularly in the case of wood.
Pour éviter que les produits puissent passer au niveau du bord extérieur des couteaux, on propose d'autre part de disposer dans le carter en dessous du jeu de couteaux en étoile, une' bague contre la paroi interne dudit carter. To avoid that the products can pass at the outer edge of the knives, it is also proposed to have in the casing below the set of star knives, a 'ring against the internal wall of said casing.
I1 est en outre avantageux de prévoir entre le broyeur préliminaire et le jeu de couteauEen étoile, des ergots sur la paroi interne de l'enceinte contenantles couteaux. I1 is also advantageous to provide between the preliminary grinder and the set of knife star, lugs on the inner wall of the enclosure containing the knives.
Ainsi, on empêche d'une part tout blocage ou coincement des produits et l'on obtient, notamment dans le cas du bois, un degré de concassage encore plus fin.Thus, on the one hand, any blocking or jamming of the products is prevented and an even finer degree of crushing is obtained, especially in the case of wood.
Le concassage ou le broyage permet d'obtenir des produits encore plus réduits lorsqu'en dessous du jeu de couteaux en étoile on prévoit un ou plusieurs marteaux. Crushing or grinding makes it possible to obtain even more reduced products when one or more hammers are provided below the set of star knives.
Lorsqu'il s'agit de broyer ou de concasser des quantités importantes de produits, on disposera avantageusement les uns à coté des autres plusieurs jeux de couteaux. When it comes to grinding or crushing large quantities of products, there are advantageously one next to the other several sets of knives.
L'invention sera mieux comprise et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaitront plus clairement au cours de la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant un mode de réalisation de l'invention et dans lesquels

- Figure 3 shows in a the preliminary mill in a top view, in b a side view on the width of the latter and in c a side view along its length; and
- Figure 4 shows the device equipped with a set of knives and several hammers.
Le jeu de couteaux disposé à l'intérieur d'un carter 6 de forme cylindrique est formé d'un broyeur préliminaire 1 dont les extrémités de couteaux, dans le sens de l'axe longitudinal, sont disposées en vis-à-vis les unes des autres en étant décalées suivant un angle de 5 à 30 . D'une manière avantageuse, l'angle précité est égal à 60. The set of knives arranged inside a casing 6 of cylindrical shape is formed by a preliminary grinder 1, the knife ends of which, in the direction of the longitudinal axis, are arranged opposite one another. others by being offset at an angle of 5 to 30. Advantageously, the above-mentioned angle is equal to 60.
En dessous du broyeur préliminaire 1, on a prévu un jeu de couteaux en étoile dont le couteau plat supérieur 3 est recourbé vers le haut. L'angle de courbure d; du couteau précité est avantageusement égal à 150. Les couteaux plats 3 présentent un angledUncESnce de 80à 120 si bien que l'on empoche tout coincement des produits à couper. Below the preliminary grinder 1, a set of star knives is provided, the upper flat knife 3 of which is bent upwards. The angle of curvature d; of the aforementioned knife is advantageously equal to 150. The flat knives 3 have an angledUncESnce of 80 to 120 so that any jamming of the products to be cut is prevented.
Dans l'enceinte contenant les couteaux, entre le broyeur préliminaire 1 et le jeu de couteaux en étoile 2, on a prévu des ergots 7 ou parties en saillie. In the enclosure containing the knives, between the preliminary grinder 1 and the set of star knives 2, pins 7 or protruding parts are provided.
En dessous du jeu de couteaux en étoile 2, dans le carter 6, on a prévu une bague 4 qui dépasse de la paroi interne du carter vers l'intérieur. L'écartement de la bague 4 par rapport au couteau plat 3 situé au niveau le plus bas est avantageusement égal à 5 mm. Below the set of star knives 2, in the casing 6, a ring 4 is provided which protrudes from the internal wall of the casing inwards. The spacing of the ring 4 relative to the flat knife 3 located at the lowest level is advantageously equal to 5 mm.
La combinaison des caractéristiques précitées assure un broyage ou un concassage rapide et régulier du produit en particules tres fines. D'autre part, en dessous du jeu de couteaux en étoile 2,on peut disposer un ou plusieurs marteaux 8 si l'on veut obtenir un concassage ou un broyage encore plus fin des produits traités. The combination of the above characteristics ensures rapid and regular grinding or crushing of the product into very fine particles. On the other hand, below the set of star knives 2, one can have one or more hammers 8 if one wants to obtain an even finer crushing or grinding of the treated products.
Si 1 'on veut réduire des quantités importantes de produts, on peut disposer les uns à ctté des autres deux ou plusieurs jeux de couteaux. If one wants to reduce significant quantities of products, one can have next to each other two or more sets of knives.
Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et représenté qui n'aété qu'à titre d'exemple. En particulier, elle comprend tous les moyens constituant des équivalents techniques des moyens décrits, ainsi que leurs combinaisons, si celles-ci sont exécutées suivant son esprit et mises en oeuvre dans le cadre de la protection comme revendiquée.
