Abstract

This device is employed in the conventional fore-carriages of machines for harvesting corn (maize) and it is located below pairs of harvesting cylinders. It includes a rotor 6 provided with cutters (knives) 5 on its lateral surface, these cutters (knives) passing between those which are provided on a support 3 close to the ground. The support 3 protects the rotor 6 against impacts, and at the same time it prevents the ears which have fallen on the ground from becoming damaged. The rotation of the rotor 6 is transmitted from the gearbox 2 of the harvesting cylinders 7.

Description

OBJET DE L'INVENTION
La présente invention concerne un dispositif de trituration des tiges de mais et il peut être employé utilement dans les avant-trains conventionnels des machines à récolter le mais avec des avantages notables par rapport aux dispositifs connus de trituration des-tiges de malus.
OBJECT OF THE INVENTION
The present invention relates to a device for crushing corn stalks and it can be usefully used in conventional forefronts of maize harvesting machines with notable advantages compared to known devices for crushing stalks of penalty.

Le dispositif de trituration décrit ici a pour objet d'assurer le broyage des tiges, sans que les couteaux de trituration puissent entrer en contact avec le sol, des pierres ou des objets durs qui pourraient les détériorer, et même les rompre, et sans détériorer les épis tombés sur le sol. The purpose of the crushing device described here is to ensure the crushing of the stems, without the crushing knives being able to come into contact with the ground, stones or hard objects which could damage them, and even break them, and without damaging the ears of corn fallen on the ground.

ANTECEDENTS DE L'INVENTION
Traditionnellement, les dispositifs de trituration utilisés sont de divers types différents , et parmi ces derniers on peut mentionner un premier type qui est constitué par un batteur rotatif situé sous les cylindres de cueillette et qui triture les tiges qui se trouvent dans son champ d'action et un deuxième type constitué par une hélice, genre tondeuse à gazon, située également sous les cylindres de cueillette des tiges.
BACKGROUND OF THE INVENTION
Traditionally, the crushing devices used are of various different types, and among these we can mention a first type which is constituted by a rotary beater located under the picking cylinders and which crushes the stems which are in its field of action and a second type consisting of a propeller, such as a lawn mower, also located under the rod picking cylinders.

Ces deux types de broyeurs présentent le grave inconvénient qui consiste en ce qu'ils entrent trés facilement en contact avec le sol, ce qui réduit le rendement de la machine et la détériore. Egalement, lorsque des épis entiers tombent sur le sol, ces derniers sont détruits par le rotor, ce qui donne lieu à des pertes importantes de production. These two types of shredders have the serious disadvantage that they come into contact with the ground very easily, which reduces the efficiency of the machine and deteriorates it. Also, when whole ears fall on the ground, these are destroyed by the rotor, which gives rise to significant losses of production.

Par conséquent les- broyeurs conventionnels sont dépourvus de fiabilité car s'ils se détériorent ils cessent de remplir leur fonction et le cout de leur entretien est élevé en raison des nombreuses avaries qu'ils présentent. Consequently, conventional shredders are unreliable because if they deteriorate they cease to perform their function and the cost of their maintenance is high because of the numerous damage they present.

Un autre mode de broyage des tiges consis
te à doter La surface latérale des paires ce cylindres de cueillette, de couteaux situés en position longitudinale, qui, lorsque les paires de couteaux des deux cylindres se trouvent face à face, font descendre les tiges et les coupent. Cette façon de triturer les tiges présente l'inconvénient qui consiste en ce que les petits déréglages qui se produisent trés fraquemment, empêchent la coupe des tiges, ce qui fait que le dispositif manque de fiabilité.
Another mode of grinding the stems consis
te to endow The side surface of the pairs of picking cylinders with knives located in the longitudinal position, which, when the pairs of knives on the two cylinders are facing each other, lower the rods and cut them. This method of crushing the rods has the disadvantage that the small misalignments which occur very suddenly, prevent the cutting of the rods, which makes the device unreliable.

DESCRIPTION DE L'INVENTION
Le dispositif de trituration proposé est constitué par un rotor pourvu de couteaux sur sa surface latérale, et qui se trouve au dessous de chaque paire de cylindres de cueillette, ce rotor étant protégé par un support pourvu de couteaux mcnçés sur sa face interne, et qui, en coopération avec les couteaux du rotor, assurent le broyage des tiges.
DESCRIPTION OF THE INVENTION
The proposed crushing device consists of a rotor provided with knives on its lateral surface, and which is located below each pair of picking cylinders, this rotor being protected by a support provided with knives fitted on its internal face, and which , in cooperation with the blades of the rotor, ensure the grinding of the rods.

De cette favor., le dispositif de trituration est protégé contre des chocs éventuels contre le sol ou contre des cojets durs oui pourraient les détériorer ou les rompre, et, e me tens, ce support de protection évite la destructicn des épis tombés sur le sol, ce qui permet de les ramasser ensuite en parfait état. From this favor., The crushing device is protected against possible shocks against the ground or against hard cojets yes could deteriorate or break them, and, e me tens, this protective support avoids the destructicn of the ears fallen on the ground , which allows them to be picked up in perfect condition.

Le rotor est actionné par le mouvement d'une chaîne de trar.sm ssic.. qui est reliée au carter d'engrenages des cylindres de cueillette. L'entrainement du rotor n'exige qu'un effort minime et par conséquent le dispositif de trituration ne réduit pas le rendement de la machine à récolter le mais. The rotor is actuated by the movement of a trar.sm ssic .. chain which is connected to the gear housing of the picking cylinders. The rotor drive requires only minimal effort and therefore the crushing device does not reduce the performance of the corn harvesting machine.

Pour compléter la description qui va suivre et pour faciliter la compréhension des caractéristiques de l'invention, cette description est accompagnée de dessins dans les figures desquels sont représentés les détails les plus significatifs de l'invention. To complete the description which follows and to facilitate understanding of the characteristics of the invention, this description is accompanied by drawings in the figures of which are represented the most significant details of the invention.

BRAVE DESCRIPTION DES DESSINS
La figure 1 montre une vue en élévation latérale d'un avant-train de machine à récolter le mais, dans laquelle on peut voir le carter d'engrenages des cylindres de cueillette et sa liaison avec le rotor qui est isolé du sol par un support protecteur pourvu de couteaux sur sa face interne.
BRAVE DESCRIPTION OF THE DRAWINGS
Figure 1 shows a side elevational view of a maize harvesting machine front end, in which we can see the gear casing of the picking cylinders and its connection with the rotor which is isolated from the ground by a support protector provided with knives on its internal face.

La figure 2 montre une vue en section, prise le long de l'axe A-B de la figure précédente, dans laquelle on voit le rotor doté sur sa surface latérale des couteaux de coupe en position transversale, ainsi que le support qui le protège du sol. Figure 2 shows a sectional view, taken along the axis AB of the previous figure, in which we see the rotor provided on its lateral surface with cutting knives in transverse position, as well as the support which protects it from the ground .

DESCRIPTION D'UNE REALISATION PREFEREE
Dans les figures en question, et en accord avec la numérotation adoptée, on peut voir que l'avant-train de récolte est constitué, de façon générale, par les capots centraux 11 dotés de leurs guides 10 correspondants, qui servent à élever les plantes, entre les capots latéraux 12 et au moyen de la vis sans fin 13 d'entralnement des épis.
DESCRIPTION OF A PREFERRED EMBODIMENT
In the figures in question, and in accordance with the numbering adopted, it can be seen that the harvesting fore-end consists, in general, of the central covers 11 provided with their corresponding guides 10, which are used to raise the plants , between the side covers 12 and by means of the endless screw 13 for locating the ears.

L'avant train de récolte est pourvu également de bras modulaires 8 au dessous desquels sont situées les paires de cylindres 7 de cueillette du mals que portent les tiges, les chaînes d'élévation 9 des plantes étant placées au dessus de ces bras 8. The harvesting front end is also provided with modular arms 8 below which are located the pairs of picking cylinders 7 of the stalk carried by the stems, the elevation chains 9 of the plants being placed above these arms 8.

Au dessous de chaque paire de cylindres 7 de cueillette, est situé le rotor de broyage 6 pourvu de couteaux 5 sur sa surface latérale et en position transversale, et le rotor est isolé du sol par le support 3 dont la face interne est dotée de couteaux 4 qui, pendant la rotation du rotor 6, donnent lieu à la trituration des tiges. Below each pair of picking cylinders 7, is located the grinding rotor 6 provided with knives 5 on its lateral surface and in transverse position, and the rotor is isolated from the ground by the support 3 whose internal face is provided with knives 4 which, during the rotation of the rotor 6, give rise to the trituration of the rods.

Le mouvement de rotation est transmis au rotor 6 au moyen d'une chaîne 1 qui transmet Le mouvement du carter d'engrenages 2 aux cylindres 7 de cueilLette. The rotational movement is transmitted to the rotor 6 by means of a chain 1 which transmits the movement of the gear housing 2 to the cylinders 7 of cueilLette.

De cette façon, du fait que le rotor 6 est isolé du sol par le support protecteur 3, les couteaux 5 du rotor ne pourront jamais entrer en contact avec le sol, ou avec tout autre objet dur et, également, les épis de mais tombés sur le sol pourront être ramassés manuellement en parfait état, car les couteaux 5 du rotor 6 ne pourront y accéder. In this way, because the rotor 6 is isolated from the ground by the protective support 3, the blades 5 of the rotor can never come into contact with the ground, or with any other hard object and, also, the ears of but fallen on the ground can be picked up manually in perfect condition, because the blades 5 of the rotor 6 will not be able to access it.

Les couteaux du dispositif de trituratIon des tiges de mais sont facilement interchangeables. The knives of the corn stalk crushing device are easily interchangeable.

Bien entendu diverses modifications peuvent être apportées par l'homme de l'art aux dispositifs ou procédés qui viennent d'être décrits uniquement à titre d'exemple non limitatif sans sortir du cadre de l'invention.  Of course various modifications can be made by those skilled in the art to the devices or methods which have just been described solely by way of non-limiting example without departing from the scope of the invention.
