Abstract
Description
La présente invention est relative à un dispositif de sécurité pour matériel agricole et plus précisément un dispositif de sécurité pour tracteur agricole équipé d'un outil, monté à l'avant et/ou à l'arrière du tracteur au moyen d'un mécanisme de liaison, notamment un mécanisme d'attelage. The present invention relates to a safety device for agricultural equipment and more specifically a safety device for an agricultural tractor equipped with a tool, mounted at the front and / or at the rear of the tractor by means of a link, in particular a coupling mechanism.
Par outil, au sens de l'invention, on entend tout mécanisme ou machine, par exemple un rouleau apte à être attelé, porté ou traîné par un tracteur pour des applications agricoles. By tool, within the meaning of the invention, is meant any mechanism or machine, for example a roller capable of being coupled, carried or dragged by a tractor for agricultural applications.
Dans la pratique il arrive que le conducteur d'un tracteur agricole ou une personne amenée à l'assister dans son travail se trouve seul à proximité de outil porté, poussé ou tracté ou entre le tracteur et l'outil. In practice, it sometimes happens that the driver of an agricultural tractor or a person required to assist him in his work is alone near a tool carried, pushed or towed or between the tractor and the tool.
I1 existe alors des risques sérieux d'accidents et de tels accidents se sont d'ailleurs déjà produits, le conducteur ou l'assistant s 'étant trouvé happé par l'outil entre celui-ci et le tracteur. There are then serious risks of accidents and such accidents have already occurred, the driver or the assistant having been caught by the tool between the latter and the tractor.
La présente invention a pour objet de prévenir ce risque en prévoyant un dispositif de sécurité susceptible d'être actionné de l'extérieur du poste de conduite du tracteur notamment en cas de risque de danger. The object of the present invention is to prevent this risk by providing a safety device capable of being actuated from outside the tractor driving position, particularly in the event of a risk of danger.
Le dispositif de sécurité selon l'invention se caractérise par le fait qu'il comporte au moins un interrupteur de type à poussoir disposé sur le tracteur et/ou sur l'outil porté, tracté ou poussé par celui-ci, de préférence au voisinage du mécanisme de liaison de l'outil au tracteur, le ou lesdits interrupteurs étant reliés électriquement à un organe de commande du moteur du tracteur de manière telle que l'actionnement du ou de l'un des interrupteurs provoque l'arrêt immédiat dudit moteur. The safety device according to the invention is characterized in that it comprises at least one push-type switch arranged on the tractor and / or on the implement, pulled or pushed by it, preferably in the vicinity the mechanism for connecting the implement to the tractor, the said switch or switches being electrically connected to a control member of the tractor engine in such a way that the actuation of the or one of the switches causes said engine to stop immediately.
Le ou les interrupteurs utilisables selon l'invention peuvent être du type "coup de poing" tels que ceux traditionnellement utilisés dans le domaine industriel notamment pour réaliser l'arrêt d'urgence d'une machine- outil ou d'une ligne de machines-outils. L'organe de manoeuvre extérieur de l'interrupteur est constitué par un poussoir sensiblement en forme de champignon à tête aplatie actionnable le plus souvent du plat de la main. The switch or switches that can be used according to the invention can be of the "punch" type such as those traditionally used in the industrial field, in particular for carrying out the emergency stop of a machine tool or a line of machines. tools. The external operating member of the switch is constituted by a pusher substantially in the form of a mushroom with a flattened head which can most often be operated with the flat of the hand.
Le ou les interrupteurs selon l'invention peuvent être montés à demeure sur le tracteur et/ou sur le ou les outils destinés à être accouplés à celui-ci ou en variante être rapportables sur ceux-ci par exemple par fixation magnétique. The switch or switches according to the invention can be permanently mounted on the tractor and / or on the implement or implements intended to be coupled thereto or, as a variant, can be attached to them, for example by magnetic fixing.
Dans un mode de réalisation particulier de l'invention, l'organe de commande du moteur actionné à partir du ou des interrupteurs est la tirette d'actionnement de la pompe d'injection du moteur du tracteur, la manoeuvre de la tirette s'effectuant par un treuil commandé par un relais relié d'une part au ou aux interrupteurs et d'autre part au contacteur à clef de démarrage du moiteur, l'énergie électrique étant fournie par la batterie du tracteur. In a particular embodiment of the invention, the engine control member actuated from the switch (s) is the pulling rod for actuating the injection pump of the tractor engine, the pulling being operated by a winch controlled by a relay connected on the one hand to the switch (es) and on the other hand to the contactor to start the wetness key, the electrical energy being supplied by the tractor battery.
Dans le but de mieux faire comprendre l'invention, on va maintenant décrire à titre d d'exemple nullement limitatif un mode de réalisation en se référant notamment au dessin annexé dans lequel
- la figure 1 représente de manière très schématique un circuit électrique de dispositif de sécurité selon l'invention.In order to better understand the invention, we will now describe by way of nonlimiting example an embodiment with particular reference to the accompanying drawing in which
- Figure 1 very schematically shows an electrical circuit of the safety device according to the invention.
- la figure 2 illustre la mise en place du dispositif selon l'invention dans le cas d'un outil tracté. - Figure 2 illustrates the implementation of the device according to the invention in the case of a towed tool.
- la figure 3 illustre la mise en place du dispositif selon l'invention dans le cas d'un outil poussé. - Figure 3 illustrates the implementation of the device according to the invention in the case of a pushed tool.
On a représenté à la figure 1 de manière particulièrement schématique un circuit électrique du dispositif selon l'invention. There is shown in Figure 1 particularly schematically an electrical circuit of the device according to the invention.
On y voit deux interrupteurs 1 et 2 de type à poussoir coup de poing qui peuvent être montés l'un sur le tracteur, l'autre sur un outil attelé à celui-ci, les interrupteurs étant reliés à un relais 3 relié également au contacteur à clef de démarrage 4 du tracteur. L'actionnement du relais 3 provoque la manoeuvre d'enroulement d'un treuil 5 provoquant le pivotement de la tirette 6 de la pompe à injection du moteur du tracteur. We see two switches 1 and 2 of the push-button type which can be mounted one on the tractor, the other on a tool coupled to it, the switches being connected to a relay 3 also connected to the contactor starting key 4 of the tractor. The actuation of the relay 3 causes the winding operation of a winch 5 causing the pivoting of the pull tab 6 of the tractor engine injection pump.
L'énergie électrique est fournie par la batterie 7 du véhicule.Electric energy is supplied by the vehicle battery 7.
Lors d'une situation de danger, lorsque le moteur du tracteur tourne, c 'est-à-dire que le contacteur à clef de démarrage est en position de marche et que l'on actionne l'un ou l'autre des interrupteurs 1 et 2, le relais 3 bascule et actionne le treuil 5 provoquant instantanément le basculement de la tirette 6 de la pompe à injection et donc l'arrêt du moteur du tracteur. In a dangerous situation, when the tractor engine is running, that is to say that the ignition key switch is in the on position and one of the switches 1 is actuated and 2, the relay 3 switches and actuates the winch 5 instantly causing the pulling rod 6 of the injection pump to tip and therefore stopping the tractor engine.
On voit sur la figure 2 un dispositif comportant deux interrupteurs 1, 1' sur les ailes arrière du tracteur et un interrupteur 2 sur l'outil tracté. Sur la figure 3, il est prévu un interrupteur 1 sur le capot avant du tracteur et un interrupteur 2 sur l'outil poussé. FIG. 2 shows a device comprising two switches 1, 1 ′ on the rear wings of the tractor and a switch 2 on the towed implement. In FIG. 3, there is provided a switch 1 on the front cover of the tractor and a switch 2 on the pushed tool.
Bien que l'invention ait été décrite en liaison avec des modes de réalisation particuliers, il est bien évident qu'elle nty est nullement limitée et qu'on peut lui apporter de nombreuses variantes et modifications sans pour autant sortir ni de son cadre ni de son esprit, en particulier en ce qui concerne le nombre et la disposition des interrupteurs. Although the invention has been described in connection with particular embodiments, it is obvious that it is in no way limited and that it can be brought to many variations and modifications without departing from its scope or its spirit, especially with regard to the number and arrangement of switches.
De plus, l'invention n'est nullement limitée, aux outils illustrés et s'applique à tous matériels attelés, portés ou tramés à l'avant ou à l'arrière du tracteur. In addition, the invention is in no way limited to the tools illustrated and applies to all equipment harnessed, carried or screened at the front or at the rear of the tractor.
