Description

DOMAINE TECHNIQUE AUQUEL SE RAPPORTE L'INVENTIONTECHNICAL FIELD TO WHICH THE INVENTION REFERS

ARRIERE-PLAN TECHNOLOGIQUEBACKGROUND

Il existe différents types de machines destinées au fendage de bûches ou de blocs de bois, en vue d'en réduire la dimension, par exemple pour obtenir des petits morceaux de bois appelés « allume-feu » destinés à servir au démarrage d'un feu dans un foyer de cheminée, de poêle ou de barbecue notamment.There are different types of machines for splitting logs or blocks of wood, in order to reduce their size, for example to obtain small pieces of wood called "firelighters" intended to be used for starting a fire. in a fireplace, stove or barbecue particular.

Les machines actuelles comportent un tapis convoyeur sans fin pour le transport des bûches ou blocs de bois depuis une goulotte d'entrée jusqu'à une chambre de fendage équipée d'un coin de fendage (de forme droite ou à section en croix par exemple).Current machines include an endless conveyor belt for the transport of logs or blocks of wood from an entrance chute to a splitting chamber equipped with a splitting wedge (straight or cross-section for example) .

Le coin de fendage est monté à l'extrémité de la tige du piston d'un vérin hydraulique et il est animé de mouvements de va-et-vient permanents, c'est-à-dire de mouvements d'extraction et de rentrée successives de la tige de son piston par rapport au corps de vérin associé, cela selon un axe perpendiculaire à la direction d'avancement du tapis convoyeur, par des moyens de commande adaptés.The splitting wedge is mounted at the end of the piston rod of a hydraulic cylinder and is animated with constant back and forth movements, that is to say successive extraction and retraction movements. the rod of its piston relative to the associated cylinder body, that along an axis perpendicular to the direction of travel of the conveyor belt, by suitable control means.

Le mouvement d'extraction de la tige du piston de ce vérin de fendage fait pénétrer le coin de fendage dans la chambre de fendage, pour réaliser l'opération de fendage recherchée ; et le mouvement de rentrée de la tige de ce piston permet au coin de fendage de sortir de la chambre de fendage, pour initier un nouveau cycle et pour permettre aux bûches ou blocs de bois d'avancer sur le tapis convoyeur.The extraction movement of the piston rod of this splitting cylinder penetrates the splitting wedge into the splitting chamber, to achieve the desired splitting operation; and the retraction movement of the rod of this piston allows the splitting wedge to exit the splitting chamber, to initiate a new cycle and to allow the logs or blocks of wood to advance on the conveyor belt.

Le tapis convoyeur peut être réalisé en métal ou en matière plastique et/ou textile. Il est du type sans fin, c'est-à-dire que ses deux extrémités s'enroulent autour de tambours rotatifs dont l'un est associé à des moyens d'avancement, par exemple du type moteur hydraulique ou moteur électrique.The conveyor belt may be made of metal or plastic and / or textile. It is of the endless type, that is to say that its two ends are wrapped around rotating drums, one of which is associated with advancement means, for example of the hydraulic motor type or electric motor.

Le brin supérieur du tapis convoyeur porte les produits à fendre, disposés les uns à la suite des autres, qui peuvent provenir d'une goulotte d'entrée chargée par un opérateur.The upper run of the conveyor belt carries the products to be split, arranged one after the other, which can come from an entry chute loaded by an operator.

Derrière la chambre de fendage, l'extrémité aval du tapis convoyeur est généralement équipée d'une structure de réception des petits morceaux de bois obtenus, par exemple un bac de réception ou un support de sac, pour un conditionnement en vrac.Behind the splitting chamber, the downstream end of the conveyor belt is generally equipped with a structure for receiving small pieces of wood obtained, for example a receiving tray or a bag holder, for bulk packaging.

Mais les machines de fendage existantes sont relativement complexes. Elles comportent généralement de nombreux capteurs et beaucoup d'automatismes, associés à une alimentation électrique, en particulier pour gérer l'avancement du tapis convoyeur en fonction des mouvements du coin de fendage, qui pénalisent leur coût de revient et qui nécessitent bien souvent une maintenance importante.But existing splitting machines are relatively complex.

Ce tapis convoyeur 3 comporte un brin supérieur 6 destiné à servir de support aux produits 7 à fendre, par exemple des bûches de bois ou des blocs de bois.This conveyor belt 3 comprises an upper strand 6 intended to serve as a support for the products 7 to be slit, for example wood logs or blocks of wood.

Ce tapis convoyeur 3 est associé à des moyens qui assurent l'avancement de son brin supérieur 6, depuis une extrémité amont 8 correspondant au tambour d'extrémité 4, jusqu'à une extrémité aval 9, correspondant au tambour d'extrémité 5, cela dans une direction d'avancement repérée par la flèche d'orientation D.This conveyor belt 3 is associated with means which ensure the advancement of its upper run 6, from an upstream end 8 corresponding to the end drum 4, to a downstream end 9, corresponding to the end drum 5, this in a direction of travel marked by the orientation arrow D.

Les moyens d'avancement correspondants consistent ici en un moteur hydraulique 10 adapté pour entraîner en rotation, pas à pas, l'un des tambours d'extrémités du tapis convoyeur 3, en l'occurrence le tambour d'extrémité aval 5.
Le moteur hydraulique 10 est monté ici à l'une des extrémités du tambour 5.The corresponding advancing means here consist of a hydraulic motor 10 adapted to drive in rotation, stepwise, one of the end drums of the conveyor belt 3, in this case the downstream end drum 5.
The hydraulic motor 10 is mounted here at one end of the drum 5.

Le tapis convoyeur 3 peut être un tapis sans fin en matière plastique et/ou textile , de préférence il est réalisé par assemblage de lames ou barrettes métalliques, pour assurer une bonne résistance et une grande longévité.The conveyor belt 3 may be an endless belt of plastic and / or textile material, preferably it is made by assembling blades or metal bars, to ensure good strength and durability.

Au niveau de l'extrémité amont 8 du tapis convoyeur 3, on remarque la présence d'une goulotte d'entrée 11, pour le chargement de la machine en bûches ou blocs de bois 7 que l'on souhaite fendre.At the upstream end 8 of the conveyor belt 3, there is the presence of an inlet chute 11, for loading the machine in logs or blocks of wood 7 that is desired to split.

Cette goulotte 11 est aménagée juste au-dessus de l'extrémité amont 8 du tapis convoyeur 3.This chute 11 is arranged just above the upstream end 8 of the conveyor belt 3.

D'autre part, des moyens de réception, ici en forme de bac 12, sont prévus dans le prolongement de l'extrémité aval 9 du tapis convoyeur 3, pour assurer la récupération des morceaux de bois fendus, et leur mise en conditionnement (par exemple en vrac).On the other hand, means of reception, here in the form of tray 12, are provided in the extension of the downstream end 9 of the conveyor belt 3, to ensure the recovery of the pieces of split wood, and their packaging (by example in bulk).

Entre ses extrémités amont 8 et aval 9, le tapis convoyeur 3 est associé à une chambre de fendage 14, ménagée juste au-dessus de son brin supérieur 6, ici délimitée par deux plaques verticales parallèles 15 et 16.Between its upstream 8 and downstream ends 9, the conveyor belt 3 is associated with a splitting chamber 14 formed just above its upper run 6, here delimited by two parallel vertical plates 15 and 16.

Ces deux plaques 15 et 16 bordent les côtés du tapis convoyeur 3 ; elles sont agencées pour guider les produits à fendre 7 et pour assurer leur positionnement correct lors des opérations de fendage.These two plates 15 and 16 border the sides of the conveyor belt 3; they are arranged to guide the products to be slit 7 and to ensure their correct positioning during splitting operations.

La chambre de fendage 14 est associée à un coin de fendage 18, ici à section en croix, qui est positionné au-dessus du brin supérieur 6 du tapis convoyeur 3 et qui est actionné par un vérin hydraulique double effet 20, selon un axe de translation A perpendiculaire ou sensiblement perpendiculaire à la direction d'avancement D du tapis 3.The splitting chamber 14 is associated with a splitting wedge 18, here cross-sectioned, which is positioned above the upper run 6 of the conveyor belt 3 and which is actuated by a double-acting hydraulic jack 20, along an axis of rotation. translation A perpendicular or substantially perpendicular to the advancing direction D of the belt 3.

Plus précisément, le vérin hydraulique 20 comporte un corps fixe 21, solidaire du châssis 2, associé à un piston mobile interne 22 (visible sur la figure 3) muni d'une tige saillante 23.More specifically, the hydraulic cylinder 20 comprises a fixed body 21, integral with the frame 2, associated with an internal movable piston 22 (visible on the figure 3 ) having a protruding rod 23.

Le coin de fendage 18 est monté à l'extrémité libre de la tige 23.The splitting wedge 18 is mounted at the free end of the rod 23.

Le vérin hydraulique de fendage 20 est commandé par des moyens qui assurent des mouvements successifs d'extraction et de rentrée de la tige 23 de son piston 22, selon l'axe de translation A, pour mettre en oeuvre des mouvements successifs de pénétration du coin de fendage 18 dans la chambre de fendage 14, et de retrait de ce coin de fendage 18 en dehors de cette chambre de fendage 14, afin de réaliser les opérations successives recherchées de fendage des bûches ou blocs de bois 7, cela à une cadence définie (par exemple de l'ordre d'une opération de fendage toutes les 3 à 4 secondes).The hydraulic splitting jack 20 is controlled by means which ensure successive movements of extraction and retraction of the rod 23 of its piston 22, along the translation axis A, to implement successive movements of penetration of the wedge splitting 18 in the splitting chamber 14, and removal of the splitting wedge 18 outside of this splitting chamber 14, to perform the desired successive operations of splitting logs or blocks of wood 7, at a defined rate (for example of the order of a splitting operation every 3 to 4 seconds).

La pénétration du coin de fendage 18 dans la chambre de fendage 14, et son retrait, s'effectuent par l'intermédiaire d'une fente adaptée 24 aménagée dans la plaque latérale en regard 15, cette fente 24 étant ici en forme de croix.The penetration of the splitting wedge 18 into the splitting chamber 14, and its removal, is effected by means of a suitable slot 24 formed in the facing side plate 15, this slot 24 being here in the form of a cross.

Simultanément aux mouvements de va-et-vient du coin de fendage 18, le brin supérieur 6 du tapis convoyeur 3 est animé d'un mouvement d'avancement pas à pas, amont/aval, selon la direction D, pour faire avancer les produits 7 à fendre.Simultaneously with the reciprocating movements of the splitting wedge 18, the upper run 6 of the conveyor belt 3 is driven by a stepwise forward movement, upstream / downstream, along the direction D, to advance the products. 7 to crack.

Ce déplacement pas à pas du tapis convoyeur 3 est réalisé par le moteur hydraulique 10, cela pendant les phases dans lesquelles le coin de fendage 18 est extrait de la chambre de fendage 14, pour éviter de perturber les déplacements respectifs, perpendiculaires entre eux, dudit coin de fendage 18 et des produits 7 à fendre.This stepwise movement of the conveyor belt 3 is carried out by the hydraulic motor 10, during the phases in which the splitting wedge 18 is extracted from the splitting chamber 14, in order to avoid disturbing the respective displacements, perpendicular to one another, of said splitting wedge 18 and products 7 to split.

Conformément à la présente invention, le moteur hydraulique 10 pour l'avancement pas à pas du tapis convoyeur 3 est commandé par un vérin hydraulique 25 (appelé vérin de tapis dans la suite de la description) actionné par les mouvements de rentrée de la tige 23 du piston 22 du vérin de fendage 20.According to the present invention, the hydraulic motor 10 for advancing step by step conveyor belt 3 is controlled by a hydraulic cylinder 25 (called carpet jack in the following description) actuated by the retraction movements of the rod 23 piston 22 of the splitting jack 20.

Plus précisément, ce vérin de tapis 25 comporte un corps 26 solidaire du châssis 2, et un piston interne 27 (figure 3) muni d'une tige saillante 28 qui s'étend et qui est mobile en translation parallèlement à l'axe A. More specifically, this carpet jack 25 comprises a body 26 secured to the frame 2, and an internal piston 27 ( figure 3 ) provided with a projecting rod 28 which extends and which is movable in translation parallel to the axis A.

L'extrémité libre 29 de la tige de piston 28 de ce vérin de tapis 25 est orientée en regard du coin de fendage 18 ; et cette extrémité libre de tige 29 consiste en un martyre qui est destiné à coopérer avec une tête de frappe 30 équipant le coin de fendage 18, pour actionner le moteur hydraulique 10 de la manière détaillée dans la suite de la description, au cours des mouvements de rentrée de la tige de piston 23 (et en particulier plutôt en fin de ces mouvements de rentrée, lorsque le coin de fendage 18 est totalement extrait de la chambre de fendage 14).The free end 29 of the piston rod 28 of this carpet cylinder 25 is oriented facing the splitting wedge 18; and this free rod end 29 consists of a hammer which is intended to cooperate with a strike head 30 equipping the splitting wedge 18, to actuate the hydraulic motor 10 in the manner detailed in the following description, during the movements retraction of the piston rod 23 (and in particular rather at the end of these re-entry movements, when the splitting wedge 18 is completely extracted from the splitting chamber 14).

La tête de frappe 30 consiste ici en une platine qui sert de support à l'extrémité arrière du coin de fendage 18 et qui s'étend perpendiculairement à l'axe A.
Dans une variante de réalisation, cette tête de frappe peut consister en un organe indépendant du coin de fendage 18, solidaire de la tige 23 du vérin de fendage 20.The striking head 30 here consists of a plate which serves as a support for the rear end of the splitting wedge 18 and which extends perpendicularly to the axis A.
In an alternative embodiment, this striking head may consist of an independent member of the splitting wedge 18, integral with the rod 23 of the splitting jack 20.

Les opérations de frappe ou de percussion sur l'extrémité 29 de la tige 28, selon l'axe de déplacement de cette dernière, sont adaptées selon la course de déplacement souhaitée de la tige 28 et du piston 27 du vérin de tapis 25, cette course de déplacement étant fonction du pas d'avancement recherché pour le tapis convoyeur 3.The striking or percussion operations on the end 29 of the rod 28, according to the axis of displacement of the latter, are adapted according to the desired displacement stroke of the rod 28 and the piston 27 of the carpet jack 25, this displacement stroke being a function of the advancement step sought for the conveyor belt 3.

Comme expliqué dans la suite de la description, entre chaque frappe, la tige 28 du vérin 25 est adaptée pour revenir dans une position extraite maximale.As explained in the following description, between each strike, the rod 28 of the cylinder 25 is adapted to return to a maximum extracted position.

Le vérin de tapis 25 comporte des moyens pour régler cette course de déplacement de sa tige 28 et de son piston 27.
Les moyens de réglage correspondants consistent en une vis 31 à l'extrémité de laquelle est monté le martyre 29 et qui est vissée dans l'extrémité de la tige de vérin 28, par exemple en association avec un contre-écrou pour assurer son verrouillage en position.The carpet jack 25 comprises means for adjusting this displacement stroke of its rod 28 and of its piston 27.
The corresponding adjustment means consist of a screw 31 at the end of which is mounted the martyr 29 and which is screwed into the end of the cylinder rod 28, for example in association with a locknut to ensure its locking in position.

Une possibilité de commande du vérin de fendage 20 et du vérin de tapis 25 est illustrée sur le schéma hydraulique 32 de la figure 3.A possibility of controlling the splitting cylinder 20 and the carpet cylinder 25 is illustrated in the hydraulic diagram 32 of FIG. figure 3 .

Sur ce schéma hydraulique 32, on remarque la présence d'une pompe hydraulique 33, associée à un réservoir d'huile 34, qui alimente le vérin de fendage double effet 20 par l'intermédiaire d'un dispositif inverseur hydraulique 35, classique.In this hydraulic diagram 32, there is the presence of a hydraulic pump 33, associated with an oil reservoir 34, which feeds the double-effect splitting cylinder 20 via a conventional hydraulic inverter device 35.

La pompe hydraulique 33 est commandée par des moyens de manoeuvre qui consistent ici en un moteur électrique 36.The hydraulic pump 33 is controlled by operating means which here consist of an electric motor 36.

A titre de variante, le moteur électrique 36 peut être remplacé par la prise de force d'un véhicule tracteur agricole.Alternatively, the electric motor 36 can be replaced by the PTO of an agricultural tractor.

La pompe hydraulique 33 alimente le vérin de fendage 20, via le dispositif inverseur 35, par une canalisation d'envoi d'huile 37, ici munie d'un diviseur de débit classique 38 équipé d'une molette pour le réglage manuel de la cadence du vérin de fendage 20.
Le retour d'huile au réservoir 34 s'effectue par l'intermédiaire d'une canalisation de retour 39 équipée d'un filtre 40.The hydraulic pump 33 feeds the splitting jack 20, via the inverter device 35, via an oil delivery line 37, here provided with a conventional flow divider 38 equipped with a knob for manual adjustment of the rate. splitting cylinder 20.
The return of oil to the tank 34 is effected by means of a return pipe 39 equipped with a filter 40.

Le dispositif inverseur de débit 35 est chargé d'envoyer l'huile provenant de la pompe hydraulique 33, alternativement dans la chambre côté fût 41, et dans la chambre côté tige 42 du vérin de fendage 20, pour obtenir le mouvement de va-et-vient recherché, cela en tenant compte d'une pression seuil d'inversement, atteinte au moment des fins de course d'extraction et de rentrée de la tige de piston 23, ou en cas de présence d'un obstacle important entre ces deux fins de course (par exemple en cas de présence d'un noeud dans une bûche).The flow inverter device 35 is responsible for sending the oil from the hydraulic pump 33, alternatively in the barrel side chamber 41, and in the rod side chamber 42 of the splitting jack 20, to obtain the movement of va-and is desired, that taking into account a reverse threshold pressure, reached at the time of extraction stroke and retraction of the piston rod 23, or if there is a significant obstacle between these two limit switches (for example if there is a knot in a log).

A titre purement indicatif, la pression seuil d'inversement du dispositif inverseur hydraulique 35 peut être de l'ordre de 135 bars.As a purely indicative indication, the inversion threshold pressure of the hydraulic reversing device 35 may be of the order of 135 bars.

On notera que le dispositif inverseur hydraulique 35 peut être remplacé par un distributeur hydraulique associé à des capteurs de fin de course, remplissant les mêmes fonctionnalités.It will be noted that the hydraulic reversing device 35 can be replaced by a hydraulic distributor associated with end-of-stroke sensors, fulfilling the same functionalities.

Entre le dispositif inverseur hydraulique 35 et le réservoir d'huile 34, la canalisation de retour d'huile 39 se divise en deux pour former :

  • une première voie 43 dirigeant l'huile vers le vérin de tapis simple effet 25, et en particulier dans la chambre interne 44 de ce vérin 25, puis, de cette chambre interne 44 vers le moteur hydraulique 10, et
  • une seconde voie 45 dirigeant l'huile vers le réservoir 34, via un clapet anti-retour taré 46 et le filtre 40 précité.
Between the hydraulic reversing device 35 and the oil reservoir 34, the oil return line 39 splits in two to form:
  • a first channel 43 directing the oil towards the single-acting carpet jack 25, and in particular in the inner chamber 44 of this jack 25, then, from this internal chamber 44 to the hydraulic motor 10, and
  • a second channel 45 directing the oil to the tank 34, via a calibrated non-return valve 46 and the aforementioned filter 40.

Le clapet anti-retour taré 46 a pour fonction d'assurer le passage de l'huile provenant de la canalisation retour 39, dans la voie 43, et donc vers le vérin de tapis 25 et le moteur hydraulique 10 associé, tant que la pression seuil de tarage associée n'est pas atteinte.The function of the calibrated check valve 46 is to ensure the passage of the oil coming from the return line 39, in the track 43, and thus to the carpet jack 25 and the associated hydraulic motor 10, as long as the pressure Associated tare threshold is not reached.

A titre purement indicatif, cette pression de tarage du clapet anti-retour 46 peut être de l'ordre de 5 bars.As a guide only, this calibration pressure of the non-return valve 46 may be of the order of 5 bars.

Cette particularité permet de mettre en pression permanente la chambre interne 44 du vérin de tapis 25, pour tendre en permanence à extraire la tige 28 de son corps 26, et donc pour que cette tige de vérin 28 soit en position extraite maximale avant de recevoir chaque percussion de la tête de frappe 30.This feature makes it possible to permanently pressurize the internal chamber 44 of the carpet jack 25, in order to permanently tend to extract the rod 28 from its body 26, and thus for this jack rod 28 to be in the maximum extracted position before receiving each percussion of the strike head 30.

Sur la voie 43, un clapet anti-retour 47 est placé en amont du vérin de tapis 25 pour assurer le transfert de l'huile provenant du vérin de fendage 20, dans la chambre interne 44 de ce vérin de tapis 25. En outre, en aval du vérin de tapis 25, un clapet anti-retour 48 assure le transfert de l'huile qui provient de sa chambre interne 44, vers le moteur hydraulique 10.On the track 43, a check valve 47 is placed upstream of the carpet jack 25 to ensure the transfer of the oil from the splitting jack 20, in the inner chamber 44 of the carpet jack 25. In addition, downstream of the carpet cylinder 25, a check valve 48 ensures the transfer of the oil which comes from its internal chamber 44, towards the hydraulic motor 10.

Un limiteur de pression 50 est prévu juste en amont du moteur hydraulique 10, pour assurer sa protection contre une pression trop importante dans le circuit, qui pourrait être engendrée par un blocage du tapis (par exemple lié à l'insertion d'un morceau de bois entre deux de ses barrettes constitutives).A pressure limiter 50 is provided just upstream of the hydraulic motor 10, to ensure its protection against excessive pressure in the circuit, which could be caused by a blockage of the carpet (for example linked to the insertion of a piece of wood between two of its constituent bars).

En aval du moteur hydraulique 10, la voie 43 retourne vers le réservoir 34. Elle rejoint ici la voie 45 de la canalisation retour 39, entre le clapet anti-retour taré 46 et le filtre 40.Downstream of the hydraulic motor 10, the track 43 returns to the tank 34. It joins here the track 45 of the return pipe 39, between the tared non-return valve 46 and the filter 40.

En fonctionnement, on comprend que le piston 23 du vérin de fendage 20 est animé d'un mouvement de va-et-vient permanent, qui assure le fendage des bûches ou blocs de bois 7 positionnés en regard dans la chambre de fendage 14, au moyen du coin de fendage 18.
En outre, au cours des mouvements de rentrée de ce piston 23, lorsque le coin de fendage 18 s'est retiré de la chambre de fendage 44, la tête de frappe 30 vient percuter la tige 28 du vérin de tapis 25, provoquant ainsi la rentrée de cette tige 28 dans son corps 26, et le déplacement du piston 27 associé, dans la direction inverse de celle tendant à l'extraction de ladite tige 28.In operation, it is understood that the piston 23 of the splitting jack 20 is driven in a constant back-and-forth movement, which splits the logs or blocks of wood 7 positioned opposite each other in the splitting chamber 14, average of the splitting wedge 18.
In addition, during the retraction movements of this piston 23, when the splitting wedge 18 has withdrawn from the splitting chamber 44, the striking head 30 strikes the rod 28 of the carpet jack 25, thus causing the return of this rod 28 in his body 26, and the displacement of the associated piston 27, in the direction opposite to that tending to the extraction of said rod 28.

Ce déplacement du piston 27 réduit le volume de la chambre de vérin 44 et expulse l'huile qu'elle contient en direction du moteur hydraulique 10 qui assure alors la rotation du tambour d'extrémité 5 du tapis convoyeur 3, de la valeur d'un pas d'avancement.This displacement of the piston 27 reduces the volume of the cylinder chamber 44 and expels the oil contained therein towards the hydraulic motor 10 which then ensures the rotation of the end drum 5 of the conveyor belt 3, the value of a step forward.

La même opération se renouvelle à chaque cycle de fendage, pour obtenir l'avancement pas à pas recherché du tapis convoyeur 3.The same operation is repeated at each splitting cycle, to obtain the desired stepwise advancement of the conveyor belt 3.

Comme expliqué précédemment, le pas d'avancement du tapis convoyeur 3 est réglé par le volume d'huile déplacé dans la chambre interne 44 par le piston de vérin 27, ce volume étant lui-même défini par la course de la tige de vérin 28, réglée par la vis 31.As previously explained, the advancing step of the conveyor belt 3 is regulated by the volume of oil displaced in the internal chamber 44 by the jack piston 27, this volume being itself defined by the stroke of the jack rod 28. , adjusted by screw 31.

On obtient une machine de fendage dont l'avancement pas à pas de son tapis convoyeur 3 est géré mécaniquement et hydrauliquement de manière simple et peu onéreuse, par le mouvement du vérin de fendage 20.A splitting machine is obtained, the stepwise advancement of its conveyor belt 3 is mechanically and hydraulically managed in a simple and inexpensive manner, by the movement of the splitting jack 20.

A titre de variante, le moteur hydraulique 10 peut être remplacé par tout autre moyen assurant l'avancement pas à pas du tapis convoyeur 3, géré par le mouvement du coin de fendage 20, par exemple une roue à rochet, ou autre.Alternatively, the hydraulic motor 10 can be replaced by any other means ensuring the advancement step by step conveyor belt 3, managed by the movement of the splitting wedge 20, for example a ratchet wheel, or other.
