Abstract

Apparatus intended for sharpening the ends of wooden posts and stakes. The invention is mainly provided with two vertical circular saws 9 positioned on a support 10, which pivots on a beam 1 under the action of a jack 12, which gives a vertical path to the said circular saws 9 driven in a rotary movement by the drive force of a tractor by the interposition of transmission shafts 3 and 10, a universal joint 4, pulleys 2 and 7 and belts 6 etc. under which circular saws 9 a stop 20 is positioned.

Description

L'appareil objet de l'invention est destiné à appcinter les extrémités des poteaux en bois pour différents usages et plus particulièrement les piquets pour la vigne. The device which is the subject of the invention is intended for appcintering the ends of wooden poles for different uses and more particularly the stakes for the vine.

La vigne est constituée par des arbrisseaux sarmenteux, grimpants et munis de vrilles, lesquels arbrisseaux ont leurs branches qui s'agrippent à des piquets en bois, ces derniers sont enfoncés dans la terre par leur extrémité pointue. The vine is made up of sarmentous shrubs, climbing and provided with tendrils, which shrubs have their branches which cling to wooden stakes, the latter are driven into the ground by their pointed end.

Actuellement, les piquets de vigne, comme les poteaux de clôture des prairies, sont appointés généralement à la hachette, représentant une tâche longue et pénible.Currently, vine stakes, like fence posts on the prairies, are generally used with a hatchet, representing a long and painful task.

La présente invention supprime le caractère fatiguant de la tâche et donne un rendement bien supérieur à la méthode manuelle. En outre, l'affûtage est régulier sur tout le pourtour de l'extrémité du piquet ou poteau. The present invention eliminates the tiring nature of the task and gives a much higher yield than the manual method. In addition, the sharpening is regular around the entire periphery of the end of the stake or post.

L'appareil objet de l'invention est principalement muni de deux scies circulaires verticales caractérisées en ce qu' elles sont positionnées proches l'une de l'autre sur un même plan horizontal. Les deux scies circulaires sont espacées et positionnées de manière à former un angle constant de 450 environ durant l'opération de sciage, lequel angle peut être augmenté ou diminué par un réglage manuel avant l'appointage, selon que les piquets doivent possèder ùne pointe plus ou moins allongée. The apparatus object of the invention is mainly provided with two vertical circular saws characterized in that they are positioned close to one another on the same horizontal plane. The two circular saws are spaced and positioned so as to form a constant angle of approximately 450 during the sawing operation, which angle can be increased or decreased by manual adjustment before filling, depending on whether the stakes have a larger point or less elongated.

Lesdites scies circulaires sont portées par un ensemble support mobile, déporté sur un côté d'une poutre, lequel support est actionné par un vérin hydraulique ou pneumatique positionné sur un châssis longitudinal. Les deux scies circulaires verticales entrainées simultanément par la force motrice du tracteur par tous moyens appropriés, descendent sur une extrémité du piquet, laquelle extrémité est immobilisée sur une butée fixée sur le châssis, sur la trajectoire desdites scies circulaires. A chaque descente des scies circulaires, le piquet est appointé simultanement sur deux faces et après une première descente, le piquet est retiré pour subir manuellement une rotation de 90 , permettant aux scies circulaires d'appointer les deux autres faces restantes. Said circular saws are carried by a mobile support assembly, offset on one side of a beam, which support is actuated by a hydraulic or pneumatic jack positioned on a longitudinal chassis. The two vertical circular saws driven simultaneously by the driving force of the tractor by any appropriate means, descend on one end of the stake, which end is immobilized on a stop fixed to the chassis, on the path of said circular saws. With each descent of the circular saws, the stake is punched out simultaneously on two faces and after a first descent, the stake is removed to undergo a manual rotation of 90, allowing the circular saws to land the other two remaining faces.

Il en résulte que deux opérations de sciage permettent d'appointer le piquet.As a result, two sawing operations make it possible to point the stake.

L'appareil peut être monté sur deux roues, mais plus généralement, pour commodité, il sera porté par un attelage trois points d'un tracteur agricole. The device can be mounted on two wheels, but more generally, for convenience, it will be carried by a three-point hitch of an agricultural tractor.

L'appareil objet de l'invention sera mieux compris par la description ci-après avec références aux dessins annexés, qui illustrent à titre d'exemple non limitatif un montage. The device which is the subject of the invention will be better understood from the description below with reference to the appended drawings, which illustrate, by way of non-limiting example, an assembly.

La figure 1 represente succintement, en vue de dessus, l'ensemble de l'appareil
La figure 2 représente partiellement, en élévation, l'appareil selon le côté indiqué par la flèche A portée sur la figure 1.
Figure 1 shows briefly, in top view, the entire device
FIG. 2 partially represents, in elevation, the apparatus according to the side indicated by the arrow A carried in FIG. 1.

L'appareil objet-de l'invention est placé sur un châssis constitué principalement d'tine poutre 1, sur laquelle est positionnée à ses deux extrémités une poulie 2 verticale à double gorge qui est entraînée par une force motrice d'un tracteur (non représenté) par l'entremise d'arbres de transmission 3, de cardans 4 et de paliers 5, lesquelles poulies 2 correspondent respectivement par l'entremise de courroies 6, positionnées sur un plan horizontal et sensiblement perpendiculaires à la poutre 1, avec des poulies 7 à double gorge positionnées respectivement sur une extrémité des arbres de transmission 8, lesquels sont sensiblement dans un même plan horizontal et ont l'autre extrémité très proche qui portent respectivement une scie circulaire 9. The apparatus object of the invention is placed on a chassis mainly consisting of a beam 1, on which is positioned at its two ends a vertical pulley 2 with double groove which is driven by a driving force of a tractor (not shown) by means of transmission shafts 3, cardan shafts 4 and bearings 5, which pulleys 2 correspond respectively by means of belts 6, positioned on a horizontal plane and substantially perpendicular to the beam 1, with pulleys 7 with double grooves positioned respectively on one end of the transmission shafts 8, which are substantially in the same horizontal plane and have the other very close end which respectively carry a circular saw 9.

Les deux arbres de transmission 8, qui portent les deux poulies 7 et les deux scies circulaires 9, sont maintenus sur un support 10 par des paliers 11, lequel support 10 pivote verticalement sur la poutre 1 sous l'action d'un vérin 12 hydraulique à double effet par l'entremise d'une traverse 23 soudée à un axe 24 pivotant, lequel est maintenu sur ladite poutre 1 par des paliers 25. Le vérin 12 est sout-enu à une extrémité par l'extrémité supérieure d'un poteau 13 vertical soudé sur un support 14 fixé à la poutre 1 et l'autre extrémité dudit vérin 12 s'appuie sur le support 10 mobile dans le voisinage immédiat des scies circulaires 9. The two transmission shafts 8, which carry the two pulleys 7 and the two circular saws 9, are held on a support 10 by bearings 11, which support 10 pivots vertically on the beam 1 under the action of a hydraulic cylinder 12 double-acting by means of a cross-member 23 welded to a pivoting pin 24, which is held on said beam 1 by bearings 25. The jack 12 is supported at one end by the upper end of a post 13 vertical welded to a support 14 fixed to the beam 1 and the other end of said jack 12 rests on the support 10 movable in the immediate vicinity of the circular saws 9.

Le vérin 12 régularise la descente des scies circulaires 9 permettant une approche douce sur le piquet 15 et permet la remontée desdites scies circulaires. La remontée peut être commandée manuellement en-agissant sur la commande 16 du vérin 12, ou automatiquement- lorsque la traverse 17 appuie sur la pièce de contact 18, cette pression s'effectue quand les scies circutaires 9 sont en fin de course. The jack 12 regulates the descent of the circular saws 9 allowing a gentle approach to the stake 15 and allows the ascent of said circular saws. The ascent can be controlled manually by acting on the control 16 of the jack 12, or automatically- when the crosspiece 17 presses on the contact piece 18, this pressure is effected when the circular saws 9 are at the end of their travel.

Les pièces concourant au fonctionnement du vérin 12 sont reliées par des flexibles (non représentés) selon les techniques en usage, autorisant l'utilisation de la force hydraulique d'un tracteur agricole.The parts contributing to the operation of the jack 12 are connected by hoses (not shown) according to the techniques in use, authorizing the use of the hydraulic force of an agricultural tractor.

Les cardans 4 permettent de donner une direction légérement différente aux courroies 6 nour obtenir un écartement plus important entre les poulies 7 par rapport aux poulies 2 de manière à déporter la direction des deux arbres de transmission 8 vers l'arrière de l'appareil pour positionner les scies circulaires 9 de façon à obtenir un angle de 45" environ formant généralement l'angle d'appointage des piquets 15. The gimbals 4 make it possible to give a slightly different direction to the belts 6 nour obtain a greater spacing between the pulleys 7 compared to the pulleys 2 so as to shift the direction of the two transmission shafts 8 towards the rear of the device to position the circular saws 9 so as to obtain an angle of approximately 45 "generally forming the angle of the stake 15.

Au-dessous et au milieu de la trajectoire des scies circulaires 9, est fixé un support 19 par soudure sur la poutre 1, lequel support 19 porte une butée 20 formée d'un fer plat horizontal surmonté d'un fer plat vertical, lequel possède des -pointes 21 sur toute sa hauteur,qui pénétrent
dans l'extrémité du piquet 15 pour le maintenir et ltempêcher de pivoter lors du sciage en pointe-. Ladite butée 20 est fixée sur le support 19 par vis et écrous et sa position peut être avancée ou reculée sur le support 19 permettant d'obtenir un appointage plus ou moins long. Le poteau 13 portant l'extrémité supérieure du vérin 12, est consolidé par un tendeur 22, lequel a son extrémité inférieure sur le support 14.
Below and in the middle of the trajectory of the circular saws 9, is fixed a support 19 by welding on the beam 1, which support 19 carries a stop 20 formed of a horizontal flat iron surmounted by a vertical flat iron, which has -21 points over its entire height, which penetrate
in the end of the stake 15 to hold it and prevent it from pivoting during point sawing. Said stop 20 is fixed on the support 19 by screws and nuts and its position can be advanced or moved back on the support 19 allowing a more or less long filling. The post 13 carrying the upper end of the jack 12 is consolidated by a tensioner 22, which has its lower end on the support 14.

L'appareil pour l'exemple ci-dessus, est porté par un attelae trois points 26 et peut etre utilisé en poste fixe dans un atelier comme sur un chantier.  The apparatus for the example above, is carried by a three-point hitch 26 and can be used in a fixed position in a workshop as on a site.
