Abstract

Double acting hydraulic actuators (1,6,14) are supplied by a hydraulic distributor controlled by an electro-hydraulic interrupter. The interrupter is located on the cutter advance lever in the cabin (23). These actuators enable the folding and unfolding of the external points (22) of six rows of cutters. One actuator is fixed by a spindle on a guide frame. The sliding end of the actuator is fixed on a guide movable part by a welded metal piece. Another actuator is fixed on a spindle supported by a metal piece welded onto another frame, the sliding end being fixed on the points' locking lever.

Description

La présente invention concerne un dispositif d'assistance hydraulique de dépliage et de repliage des becs extérieurs d'ensileuses à mals 6 rangs. The present invention relates to a hydraulic assistance device for unfolding and folding the outer nozzles of 6-row male forage harvesters.

Les opérations de dépliage et de repliage sont habituellement effectuées manuellement, obligeant le conducteur à descendre et monter de l'ensileuse à chaque changement de parcelles et à des manutentions pénibles pouvant provoquer des risques d'accidents . coincement des mains, entorses aux chevilles, problèmes de dos. The unfolding and folding operations are usually carried out manually, forcing the driver to get on and off the forage harvester at each change of plots and painful handling operations which can cause risks of accidents. hand trapping, ankle sprains, back problems.

Ce dispositif est constitué de six vérins hydrauliques à double effet (3 par coté), alimentés par un distributeur hydraulique, lui même commandé par un interrupteur électro-hydraulique situé sur le levier d'avancement de l'ensileuse qui est installé dans la cabine de pilotage. This device consists of six double-acting hydraulic cylinders (3 per side), supplied by a hydraulic distributor, itself controlled by an electro-hydraulic switch located on the forward lever of the forage harvester which is installed in the cab of steering.

Les dessins annexés illustrent le dispositif
La figure 1 représente l'action du vérin pour le dépliage et le repliage du guide
La figure 2 représente l'action du vérin sur la manette de débrayage des chaines de becs permettant le déverrouillage des becs extérieurs afin de les mettre en position de travail.The accompanying drawings illustrate the device
Figure 1 shows the action of the cylinder for unfolding and folding the guide
FIG. 2 represents the action of the jack on the declutching lever of the spout chains allowing the unlocking of the outer spouts in order to put them in the working position.

La figure 3 représente l'action du vérin pour le dépliage et le repliage des becs extérieurs.FIG. 3 represents the action of the jack for unfolding and folding the outer spouts.

La figure 4 représente le taquet de verrouillage de sécurité du bec en position repliée.Figure 4 shows the safety locking tab of the spout in the folded position.

La figure 5 représente la mise en place d'un ressort qui permet la remise en place automatique du couvercle de bec.Figure 5 shows the establishment of a spring which allows the automatic replacement of the spout cover.

La figure 6 représente les becs et les guides dépliés en position de travail.Figure 6 shows the spouts and guides unfolded in the working position.

La figure 7 représente les becs et les guides repliés en position de transport.FIG. 7 shows the spouts and the guides folded back in the transport position.

En référence à ces dessins
Figure 1 : un vérin hyraulique à double effet (1) est fixé par un axe (2) sur le bâti (3) du guide, l'extrémité coulissante du vérin fixée sur la partie mobile (4) du guide par l'intermédiaire de la pièce métalique (5) spécialement soudée à cet effet.With reference to these drawings
Figure 1: a double-acting hydraulic cylinder (1) is fixed by an axis (2) on the frame (3) of the guide, the sliding end of the cylinder fixed on the movable part (4) of the guide via the metal part (5) specially welded for this purpose.

Figure 2 : un vérin hydraulique à double effet (6) est fixé sur un axe (7) supporté par une pièce métallique (8) soudée sur le bâti (9), l'extrémité coulissante du vérin étant fixée sur la manette (10) de déverrouillage des becs et permettant d'actionner celle-ci. Figure 2: a double-acting hydraulic cylinder (6) is fixed on an axis (7) supported by a metal part (8) welded to the frame (9), the sliding end of the cylinder being fixed on the handle (10) unlocking the spouts and allowing to activate it.

Figure 3 : un axe (11) est fixé sur le support (12) de l'axe du ressort d'assistance (13) afin de maintenir le vérin double effet (14). L'axe (15) est remplacé par un axe plus long et permettant de maintenir à la fois l'autre extrémité du ressort d'assistance (13) et l'extrémité coulissante du vérin
Figure 4 : le taquet de verrouillage de sécurité (16) du bec en position repliée est désolidarisé de l'élément mobile du bec par suppression des pièces servant à le maintenir en position de verrouillage. Un nouveau verrou de sécurité (17) est fixé sur le bâti (18) de telle manière qu'il bloque le taquet (16) quand le bec est replié. Ce taquet (16) n'est actionné manuellement que lors des déplacements sur route.Figure 3: an axis (11) is fixed on the support (12) of the axis of the assistance spring (13) in order to maintain the double-acting cylinder (14). The axis (15) is replaced by a longer axis and making it possible to maintain both the other end of the assistance spring (13) and the sliding end of the jack
Figure 4: the safety locking tab (16) of the spout in the folded position is detached from the movable element of the spout by removing the parts used to keep it in the locking position. A new security lock (17) is fixed on the frame (18) in such a way that it blocks the cleat (16) when the spout is folded. This cleat (16) is actuated manually only when traveling on the road.

Figure 5 : un ressort (19) est fixé sur la tôle du bec (20) l'autre extrémité du ressort est fixée sur le couvercle (21) et permet la remise en place automatique du couvercle (21) lors du dépliage du bec.Figure 5: a spring (19) is fixed on the sheet metal of the spout (20) the other end of the spring is fixed on the cover (21) and allows the automatic replacement of the cover (21) when unfolding the spout.

Le dispositif décrivant les figures 1, 2, 3, 4 et 5 concerne un côté des becs et il est bien entendu qu'il s'applique de la même façon de l'autre côté chaque extrémité des becs étant identique et devant se déplier et replier en même temps.The device describing Figures 1, 2, 3, 4 and 5 relates to one side of the spouts and it is understood that it applies in the same way on the other side each end of the spouts being identical and having to unfold and fold at the same time.

Le dispositif est particulièrement destiné à équiper les becs six rangs repliables de marque CLASS ou étant conçus sur le même principe. The device is particularly intended to equip the six-row folding spouts of the CLASS brand or being designed on the same principle.
