Abstract

The agricultural implement comprises a cultivator with tools, behind which there is a roller, a fertiliser distributor or a seed drill, or a three-point lifting frame. The latter allows the drill to be moved forwards and upwards into a travel position. Stops (10) are provided on the outside (9) of the cultivator (1), engaging with components of the drill (16) when this is in the travel position, and typically against its wheels (17), which can be pneumatic-tyred. The stops can be adjustable.

Description

Assemblage d'instruments agricoles
L'invention concerne un assemblage d'instruments agricoles comprenant un cultivateur avec ses outils derrière lequel est raccordé un rouleau, une machine d'épandage ou semoir relié à l'instrument de travail du sol par des éléments d'accouplement constitués comme un bâti de levage à attelage trois points, ce semoir pouvant être déplacé, à l'aide du bâti de levage, vers l'avant et vers le haut en direction de la marche, dans une position de transport.Assembly of agricultural implements
The invention relates to an assembly of agricultural implements comprising a cultivator with its tools behind which is connected a roller, a spreading machine or seed drill connected to the tillage implement by coupling elements constituted as a frame of lifting with three-point hitch, this seed drill can be moved, using the lifting frame, forward and upward in the direction of travel, in a transport position.

Un tel assemblage d'appareils est déjà connu d'après le modèle d'usage DE 81 04 256, et il a fait ses preuves dans la pratique. L'avantage principal de cette combinaison réside en ce qu'au moyen d'un bâti de levage, le semoir peut être déplacé vers l'avant et vers le haut dans une position de transport.Cette disposition permet de réduire jusqu'à 30 % la force de levage demandée au système de levage du tracteur
Dans le cas de très grandes largeurs de travail et de conditions de travail extrêmement sévères, il a été constaté que, malgré une exécution très stable du bâti de levage, on n'atteint pas dans tous les cas une position de repos satisfaisante du semoir, c'est-à-dire que cet instrument exécute des oscillations sur un axe vertical en direction de la marche et en direction opposée. I1 en résulte que l'ensemble de la combinaison d'appareils est soumis à des oscillations qui se transmettent également au tracteur, de telle sorte que la sécurité du transport n est plus assurée.Such an assembly of devices is already known from the usage model DE 81 04 256, and it has proven itself in practice. The main advantage of this combination is that by means of a lifting frame, the seed drill can be moved forwards and upwards in a transport position. This arrangement makes it possible to reduce up to 30% the lifting force required from the tractor lifting system
In the case of very large working widths and extremely severe working conditions, it has been found that, despite a very stable execution of the lifting frame, in all cases a satisfactory rest position of the seed drill is not reached, that is, this instrument performs oscillations on a vertical axis in the direction of travel and in the opposite direction. As a result, the entire combination of devices is subjected to oscillations which are also transmitted to the tractor, so that transport safety is no longer guaranteed.

La présente invention a pour but de permettre que l'on assure que le transport est exempt d'oscillations, notamment avec des combinaisons d'appareils à très grandes largeurs de travail. The present invention aims to allow that it is ensured that the transport is free of oscillations, especially with combinations of devices with very large working widths.

Dans ce but la combinaison d'appareils conforme à l invention est caractérisée en ce que, dans la zone extérieure de la machine de travail du sol, sont disposées des butées qui, lorsque le semoir se trouve en position de transport, s'engagent en coopération avec des éléments de ce semoir. For this purpose, the combination of devices according to the invention is characterized in that, in the external zone of the soil working machine, stops are arranged which, when the seed drill is in the transport position, engage in cooperation with elements of this seed drill.

De cette manière, on évite une liaison entre le semoir et la machine de travail du sol sur un axe vertical, de telle sorte que le semoir ne peut exécuter aucune oscillation en direction de la marche ou en direction opposée. In this way, a connection is avoided between the seed drill and the soil working machine on a vertical axis, so that the seed drill cannot execute any oscillation in the direction of travel or in the opposite direction.

Suivant un mode de réalisation recommandé, il est prévu par l'invention que les butées viennent s'appuyer sur les roues. On obtient ainsi une construction très simple et il est possible de monter après coup de telles butées sur des combinaisons d'appareils déjà existantes. According to a recommended embodiment, it is provided by the invention that the stops come to bear on the wheels. A very simple construction is thus obtained and it is possible to mount such abutments after the fact on combinations of already existing devices.

L'avantage apparalt surtout lorsque les roues sont réalisées sous forme de bandages en caoutchouc. Les bandages en caoutchouc qui viennent alors en contact avec les butées agissent comme amortisseurs. En outre, les roues soumises à une pression poussent le semoir au moins sur une petite distance dans la direction de la position de travail, ce qui peut permettre de franchir le point mort du bâti de levage. D'autre part, les bandages pneumatiques, lorsqu'ils viennent s'appliquer contre les butées, freinent lentement le semoir décalé vers le haut, sur la dernière partie de son parcours en rotation vers l'avant et vers le haut, de telle sorte que les forces d'inertie produites par ce freinage sont amoindries.The advantage appears especially when the wheels are made in the form of rubber tires. The rubber tires which then come into contact with the stops act as shock absorbers. In addition, the wheels subjected to pressure push the seed drill at least a small distance in the direction of the working position, which can make it possible to cross the neutral point of the lifting frame. On the other hand, the pneumatic tires, when they come to bear against the stops, slowly brake the seed drill offset upwards, on the last part of its course in rotation forward and upward, so that the inertial forces produced by this braking are reduced.

En vue de permettre l'adaptation optimale des butées à des machines de culture et semoirs différents, il est prévu qu'elles sont réglables. In order to allow the optimal adaptation of the stops to different cultivation machines and seeders, it is intended that they are adjustable.

L'invention est expliquée ci-après avec référence à la figure unique annexée représentant une vue en élévation latérale d'un exemple de réalisation de la combinaison d'appareils. The invention is explained below with reference to the single appended figure representing a side elevation view of an exemplary embodiment of the combination of devices.

La combinaison d'appareils se compose d'un appareil de travail du sol constitué par un cultivateur rotatif 1, auquel est relié, par des bras 2, un rouleau 3, et d une machine d'épandage constituée par un semoir mécanique 4. The combination of devices consists of a soil working device constituted by a rotary cultivator 1, to which is connected, by arms 2, a roller 3, and a spreading machine constituted by a mechanical seed drill 4.

Ce semoir 4 est relié au cultivateur 1 par l'intermédiaire de pièces d'accouplement constituant un bâti de levage 5.This seed drill 4 is connected to the cultivator 1 by means of coupling pieces constituting a lifting frame 5.

Ce bâti comprend deux points d'attelage inférieurs 6 et un 3ème point d'attelage supérieur 7. A l'aide du vérin hydraulique 8, qui est raccordé par la conduite 8' au système hydraulique du tracteur, le bâti de levage 5 peut tourner dans le plan vertical. Par cette manoeuvre, le semoir 4, qui est raccordé au bâti de levage 5, peut être déplacé, à partir de sa position de service, vers l avant et vers le haut, dans la position de transport représentée à la figure.This frame includes two lower coupling points 6 and a third upper coupling point 7. By means of the hydraulic cylinder 8, which is connected by line 8 ′ to the hydraulic system of the tractor, the lifting frame 5 can rotate in the vertical plane. By this maneuver, the seed drill 4, which is connected to the lifting frame 5, can be moved, from its operating position, forward and upward, into the transport position shown in the figure.

Dans les zones 9 extérieures du cultivateur rotatif 1, sont prévues les butées 10 qui sont constituées chacune par une plaque de tôles 12 verticale, boulonnée sur la partie extérieure du châssis 11 du cultivateur rotatif 1. In the external zones 9 of the rotary cultivator 1, the stops 10 are provided, which each consist of a vertical sheet plate 12, bolted to the external part of the frame 11 of the rotary cultivator 1.

Sur l'extrémité supérieure de chacune des plaques de tôle 12, est fixé par soudage un tuyau 13 dans lequel est engagé un autre tuyau 14 qui peut être immobilisé, au moyen de vis 15, dans différentes positions de réglage.On the upper end of each of the sheet plates 12, is fixed by welding a pipe 13 in which is engaged another pipe 14 which can be immobilized, by means of screws 15, in different adjustment positions.

Sur le côté du tuyau 14 qui est orienté vers le semoir 4, est soudé un tuyau transversal 16, lequel- coopère comme butée 10 avec le semoir 4 dans sa position de trans port, c est-à-dire que ce tuyau transversal 16 vient s appliquer contre les roues du semoir 4 réalisées sous la forme de bandages pneumatiques 17. La butée 10, ainsi que le tuyau 14, sont alors bloqués dans le tuyau 13 au moyen des vis 15, de telle sorte que, lorsque le semoir 4 a été soulevé et totalement basculé vers le haut et vers l avant. le tuyau transversal 16 s'engage par pression dans les bandages pneumatiques 17. On obtient ainsi, dsune part, une position fixe du semoir, et, d'autre part, un amortissement du mouvement de rotation du semoir dans la dernière partie de son déplacement de soulèvement et de basculement.  On the side of the pipe 14 which is oriented towards the seed drill 4, is welded a transverse pipe 16, which cooperates as a stop 10 with the seed drill 4 in its transport position, that is to say that this transverse pipe 16 comes s apply against the wheels of the seed drill 4 made in the form of pneumatic tires 17. The stop 10, as well as the pipe 14, are then blocked in the pipe 13 by means of the screws 15, so that, when the seed drill 4 has been lifted and completely tilted up and forward. the transverse pipe 16 engages by pressure in the pneumatic tires 17. This gives, on the one hand, a fixed position of the seed drill, and, on the other hand, a damping of the rotary movement of the seed drill in the last part of its movement lifting and tilting.
