Abstract

1. Method for the gradual fragmentation of stones by way of a movable breaker comprising a rotor (9) which is height adjustable relative to a frame (1) equipped with hammers (10) which are fixed rigidly and regularly to the rotor periphery and distributed in a plurality of parallel and regularly spaced rows according to a staggered arrangement and, during rotation of the said rotor (9), brush against an anvil (17) attached to the frame (1) parallel to the rotor (9), characterised in that the method consists of the stones being pushed by the rotor (9) during the movement thereof, of restraining the said stones, and of the stones remaining under the frame (1) against the rotor (9) upstream of the anvil (17) until sufficient fragmentation is achieved by a nibbling action to allow the stones to be thrown rearwardly by passing between the hammers (10) and carried along by the successive rows of hammers.

Description

La présente invention concerne un broyeur destiné à fragmenter les pierres de dimensions trop importantes.The present invention relates to a crusher intended to fragment stones of too large dimensions.

La présence de pierres dans un champ constitue un handicap certain qui limite la production et entraine une charge d'entretien de matériels agricoles très importante ; aussi, l'épierrage s'avère-t-i1 indispensable dans de nombreuses régions.The presence of stones in a field constitutes a certain handicap which limits production and leads to a very significant maintenance charge for agricultural equipment; stone removal is therefore essential in many regions.

Ces opérations d'épierrage, délicates et assez coûteuses, s'effectuent de deux manières souvent complémentaires.These stone removal operations, delicate and quite expensive, are carried out in two often complementary ways.

La première manière consiste à ramasser les pierres et à les réunir dans un "pierrier" ; ce qui peut s'effectuer à la main, selon la méthode ancestrale ou à l'aide de moyens mécanisés.The first way is to collect the stones and bring them together in a "scree"; which can be done by hand, according to the ancestral method or using mechanized means.

La seconde manière consiste, après avoir éliminé les très grosses pierres, à réduire en gravier de 2 à 4 cm de diamètre, les pierres tendres de dimensions moyennes à l'aide de broyeurs mécanisés mis en oeuvre par un tracteur.The second way consists, after having eliminated the very large stones, to reduce in gravel from 2 to 4 cm in diameter, the soft stones of average dimensions using mechanized shredders implemented by a tractor.

Il existe actuellement, sur le marché, deux sortes principales de broyeurs ou de casseurs de pierres. La première sorte est représentée par des équipements assez volumineux destinés aux travaux publics et non adaptés aux travaux agricoles. La seconde sorte est représentée par des engins, extrapolés de débrouissailleuses, équipés de marteaux mobiles, pour éviter le bourrage, entraînés en rotation à vitesse élevée afin de maintenir les marteaux en position de travail : ce qui entraîne des effets d'inertie assez considérables qui provoquent la détérioration des prises de force et pose des problèmes d'équilibrage.There are currently two main types of stone crushers or breakers on the market. The first type is represented by fairly bulky equipment intended for public works and not suitable for agricultural work. The second kind is represented by machines, extrapolated from brushcutters, equipped with mobile hammers, to avoid jamming, driven in rotation at high speed in order to keep the hammers in the working position: which leads to fairly considerable inertia effects which cause the deterioration of the PTO and poses problems of balance.

Ces broyeurs n'acceptent pas de pierres de trop grosses dimensions ; le déséquilibre fréquent de leur rotor provoque des vibrations qui entraînent la détérioration rapide de l'ensemble tracté ; leurs marteaux s'abîment très vite et la fragmentation obtenue est assez grossière.These crushers do not accept stones of too large dimensions; the frequent imbalance of their rotor causes vibrations which cause rapid deterioration of the towed assembly; their hammers are damaged very quickly and the fragmentation obtained is fairly coarse.

Le broyeur de pierres selon l'invention, remédie aux inconvénients cités ci-dessus car son fonctionnement ne repose pas sur la frappe des pierres à broyer, mais sur leur grignotage : ce qui permet de faire tourner le rotor à une vitesse quatre fois plus lente que celle des rotors qui équipent les broyeurs existants : ce qui est rendu possible, en particulier, par la fixité des marteaux, dont le nombre permet d'obtenir un grignotage de très grosses pierres sans surchauffe des marteaux, ni déséquilibrage du rotor.The stone crusher according to the invention overcomes the drawbacks mentioned above because its operation is not based on striking the stones to be ground, but on their nibbling: which makes it possible to rotate the rotor at a speed four times slower than that of the rotors which equip existing shredders: which is made possible, in particular, by the fixity of the hammers, the number of which makes it possible to nibble on very large stones without overheating the hammers, or unbalancing the rotor.

Ce broyeur de pierres à percussion et à écrasement, se caractérise principalement en ce que les marteaux sont fixés rigidement et régulièrement à la périphérie d'un rotor et en ce qu'ils viennent tangenter une enclume fixée au châssis, en amont du rotor et parallèlement à celui-ci, en ce que la position du rotor est réglable en hauteur par rapport au châssis, en ce que les flancs du caisson entourant le rotor sont équipés d'écarteurs, en ce que l'avant du châssis est muni de plusieurs rangées de chaînes jointives suspendues et en ce que l'arrière du châssis est équipé d'un tablier articulé à débattement réglable.This impact and crushing stone crusher is mainly characterized in that the hammers are rigidly and regularly fixed to the periphery of a rotor and in that they come to tangent an anvil fixed to the chassis, upstream of the rotor and in parallel to the latter, in that the position of the rotor is adjustable in height relative to the chassis, in that the sides of the box surrounding the rotor are equipped with spacers, in that the front of the chassis is provided with several rows contiguous chains suspended and in that the rear of the chassis is equipped with an articulated apron with adjustable travel.

Les marteaux en acier de forme parallèlépipédique, dont la hauteur représente environ le tiers de leur longueur, sont soudés au rotor en tangentant celui-ci au niveau de leur arête inférieure arrière. Leur arête supérieure avant est renforcée par un apport ou une pastille de carbure de tungstène ou équivalent.The steel hammers of parallelepiped shape, the height of which represents about a third of their length, are welded to the rotor by pitching it at their lower rear edge. Their upper front edge is reinforced by an addition or a tungsten carbide pellet or equivalent.

L'enclume, fixée au châssis en avant du rotor, est constituée d'un profilé carré en acier dont l'un des côtés est disposé parallèlement au sol.The anvil, fixed to the chassis in front of the rotor, consists of a square steel profile, one of the sides of which is arranged parallel to the ground.

Les marteaux sont répartis uniformément en plusieurs rangées parallèles, régulièrement écartées, selon une disposition en quinconce. Le rotor est entrainé en rotation, en sens inverse du sens normal de rotation des roues de l'engin tracteur, par l'intermédiaire d'un arbre longitudinal, d'un renvoi d'angle, d'un arbre de transmission transversal et de poulies et courroies ou de pignons et chaînes, montés à chaque extrémité de l'arbre de transmission et de l'axe du rotor.The hammers are distributed uniformly in several parallel rows, regularly spaced, in a staggered arrangement. The rotor is rotated, in the opposite direction to the normal direction of rotation of the wheels of the towing machine, by means of a longitudinal shaft, a bevel gear, a transverse transmission shaft and pulleys and belts or sprockets and chains, mounted at each end of the drive shaft and the rotor shaft.

Le châssis, soutenu par deux rails, est constitué de deux barres de torsion reliées par des traverses.The chassis, supported by two rails, consists of two torsion bars connected by crosspieces.

Le rotor est monté dans un caisson, ouvrable par le dessus, solidaire du châssis, supporté par des paliers fixés sur les flancs du caisson par l'intermédiaire d'une platine, de boulons et de lumières, permettant le réglage vertical par rapport au sol par l'intermédiaire de dispositifs constitués de glissières solidaires du caisson, de la platine, formant coulisseau, montée entre les paliers et les parois du caisson, de vis équipées d'une manivelle et d'écrous solidaires du caisson.The rotor is mounted in a box, openable from above, secured to the chassis, supported by bearings fixed on the sides of the box by means of a plate, bolts and lights, allowing vertical adjustment with respect to the ground. by means of devices made up of slides fixed to the box, of the plate, forming a slide, mounted between the bearings and the walls of the box, of screws equipped with a crank and of nuts fixed to the box.

Des écarteurs, disposés sur les flancs, sont constitués de rebords formant patins, effilés sur l'avant, disposés à angle droit à la partie inférieure du caisson, reliés à la partie supérieure du caisson par une plaque métallique formant carter de protection pour la transmission.Spacers, arranged on the sides, consist of flanges forming pads, tapered on the front, arranged at right angles to the lower part of the box, connected to the upper part of the box by a metal plate forming a protective casing for the transmission .

  • La figure 4 représente, une vue en coupe longitudinale d'un marteau donnant le détail de son mode de fixation sur le rotor.

Other characteristics and advantages will appear in the following description of a stone crusher produced according to the invention, given by way of nonlimiting example with regard to the appended drawings in which:
  • FIG. 1 represents a view in longitudinal section of the mill.
  • Figure 2 shows a cross-sectional view of the mill.

  • FIG. 4 represents a view in longitudinal section of a hammer giving the detail of its method of attachment to the rotor.
  • Figure 5 shows, the detail of the connection mode of the bearings to the box.

En se reportant successivement aux figures des dessins, on remarque que le châssis 1 est rendu solidaire des attaches trois points 2 du tracteur par l'intermédiaire de rails 3 et que le châssis 1 supporte un caisson 4, muni d'un couvercle 5, à l'intérieur duquel est monté, par l'intermédiaire de paliers 6, réglable en hauteur par une échancrure 7 et des lumières 8, un rotor 9 à la périphérie duquel sont fixées par soudure des rangées de marteaux 10 disposés en quinconce. Le rotor 9 est entraîné en rotation par l'intermédiaire d'un arbre longitudinal 11, raccordé à la prise de mouvement du tracteur, d'un renvoi d'angle 12, d'un arbre transversal 13, de poulies 14 et 15 et de courroies 16. L'enclume 17 est montée en travers du châssis 1, en avant du rotor 9. Quatre rangées de chaînes 18, disposées en avant du rotor 9, et un tablier 19 à débattement réglable par une chaînette 20, retiennent les projections de pierres. Les marteaux 10, sont fixés,par un cordon de soudure 21, sur le rotor 9 de façon à tangenter le rotor au niveau de leur arête inférieure arrière 10a,alors que l'arête supérieure avant 10b est renforcée par un apport de carbure de tungstène 22. Les écarteurs sont constitués de rebords 23, formant patins et effilés sur l'avant, reliés par une plaque métallique 24 à la partie supérieure du caisson afin de constituer un carter protecteur pour la transmission.Referring successively to the figures of the drawings, it is noted that the chassis 1 is made integral with the three-point attachments 2 of the tractor by means of rails 3 and that the chassis 1 supports a box 4, provided with a cover 5, to the interior of which is mounted, by means of bearings 6, adjustable in height by a notch 7 and lights 8, a rotor 9 at the periphery of which are fixed by welding rows of hammers 10 arranged in staggered rows. The rotor 9 is rotated by a longitudinal shaft 11, connected to the power take-off of the tractor, a bevel gear 12, a transverse shaft 13, pulleys 14 and 15 and belts 16. The anvil 17 is mounted across the chassis 1, in front of the rotor 9. Four rows of chains 18, arranged in front of the rotor 9, and an apron 19 with adjustable movement by a chain 20, retain the projections of stones. The hammers 10 are fixed, by a weld bead 21, to the rotor 9 so as to tangent the rotor at their rear lower edge 10a, while the upper front edge 10b is reinforced by an addition of tungsten carbide 22. The spacers consist of flanges 23, forming pads and tapered on the front, connected by a metal plate 24 to the upper part of the box in order to constitute a protective casing for the transmission.

Ainsi, comme on le voit, le rotor 9, compte-tenu de son sens de rotation et de sa masse, pousse devant lui, lors de son déplacement, les grosses pierres qu'il fragmente progressivement à l'aide des marteaux.10,puisque l'enclume 17, que les marteaux viennent frôler, contraint les pierres à rester sous le châssis tout le temps que leur fractionnement n'est pas suffisant pour être rejetées en arrière par le dessus, en passant entre les marteaux 10 et en étant entraînées par les rangées successives de ceux-ci, disposés en quinconce. Pendant ces opérations, les chaînes 18 et le tablier 19 s'opposent aux projections.Thus, as can be seen, the rotor 9, taking into account its direction of rotation and its mass, pushes in front of it, during its movement, the large stones which it progressively fragments using the hammers. 10, since the anvil 17, which the hammers come to graze, forces the stones to remain under the frame all the time that their splitting is not sufficient to be thrown back from above, passing between the hammers 10 and being driven by successive rows thereof, arranged in staggered rows. During these operations, the chains 18 and the deck 19 oppose the projections.

Le couvercle 5 aménagé à la partie supérieure du caisson 4 permet d'accéder aux marteaux 10 pour vérifier leur état et les recharger si nécessaire.The cover 5 arranged at the top of the box 4 provides access to the hammers 10 to check their condition and reload them if necessary.

En se reportant à la figure 5, on remarque que l'échancrure 7 et les lumières 8 permettent, après desserrage des boulons de fixation des paliers 6 au caisson 4, de faire varier la position verticale de ceux-ci par action sur la manivelle 25 qui assure, par l'intermédiaire de l'écrou 26, de la vis 27 et de la platine 28 formant coulisseau, le déplacement précis des paliers 16-par rapport à des rainures 29 formant glissière. Il est ainsi aisé d'obtenir, par exemple, un espace de quelques centimètres entre le sol et l'extrémité des marteaux 10.Referring to Figure 5, we note that the notch 7 and the lights 8 allow, after loosening the bolts fixing the bearings 6 to the housing 4, to vary the vertical position thereof by action on the crank 25 which ensures, through the nut 26, the screw 27 and the plate 28 forming a slide, the precise movement of the bearings 16-relative to grooves 29 forming a slide. It is thus easy to obtain, for example, a space of a few centimeters between the ground and the end of the hammers 10.

Il est aussi possible, en utilisant le dispositif de relevage du tracteur, de soulever complètement l'ensemble, ce qui permet, par exemple, le démontage rapide du rotor 9 après avoir libéré les paliers 6, par démontage complet de leurs boulons de fixation, étant donné la présence de l'échancrure 7 qui permet le passage de l'arbre de rotation du dit rotor 9.It is also possible, using the tractor lifting device, to lift the assembly completely, which allows, for example, the rapid disassembly of the rotor 9 after having released the bearings 6, by complete disassembly of their fixing bolts, given the presence of the notch 7 which allows the passage of the rotation shaft of said rotor 9.

Le broyeur de pierres selon l'invention, est destiné principalement à l'épierrage des champs, mais il peut être utilisé aussi pour fragmenter des pierres dans des carrières à niveau constant ou, en réduisant la largeur de son rotor, pour creuser des tranchées dans des endroits particulièrement pierreux.The stone crusher according to the invention is intended mainly for stone removal from fields, but it can also be used to fragment stones in quarries at constant level or, by reducing the width of its rotor, to dig trenches in particularly stony places.

Entraîné en rotation par un moteur hydraulique et monté à l'extrémité de la flèche ou du bras d'engins de terrassement, il pourrait être utilisé sur des parois verticales pierreuses ou rocheuses.Rotated by a hydraulic motor and mounted at the end of the boom or arm of earth-moving machinery, it could be used on stony or rocky vertical walls.
