Abstract
Description
La présente invention concerne les appareils dits secoueurs de branches permettant la récolte mécanique des fruits. The present invention relates to so-called branch shakers for mechanical harvesting of fruit.
Dans les dispositifs connus de ce genre, les appareils ne comportent qu'un seul secoueur constitué par une poutre rigide ou un élément souple tel que câble ou chaîne. In known devices of this kind, the devices have only one shaker consisting of a rigid beam or a flexible element such as cable or chain.
Ces appareils sont d'un emploi malaisé car ils demandent le décrochage et le raccrochage de l'agent secoueur : poutre, câble ou chaîne, pour chacune des branches à secouer. Outre le temps perdu, cette contrainte présente souvent l'inconvénient d'amener le manipulateur à se déplacer sur le réceptacle de fruits, ce qui entraîne, du moins pour les fruits délicats, des altérations par écrasement, des fruits déjà chutés. These devices are difficult to use because they require the shaker to hang up and hang up: beam, cable or chain, for each of the branches to be shaken. In addition to the time lost, this constraint often has the drawback of causing the manipulator to move around the fruit receptacle, which results, at least for delicate fruits, in damage by crushing, fruit already dropped.
Le fait de disposer d'agents de secouage en nombre suffisant de manière à accrocher toutes les branches devant être secouées pour assurer la récolte de la totalité d'un arbre permet de sérier les opérations : approche de l'arbre, accrochage des branches à secouer, installation du réceptacle, secouage, retrait du réceptacle et décrochage des câbles. De ce fait un gain important de temps est réalisé et les risques d'altération des fruits supprimés. Having enough shaking agents to hang all the branches to be shaken to ensure the harvesting of an entire tree allows serial operations: approaching the tree, hanging the branches to be shaken , installation of the receptacle, shaking, removal of the receptacle and unhooking of the cables. Therefore a significant saving of time is realized and the risks of spoilage of the fruits eliminated.
Par ailleurs, chaque agent de secouage étant commandé séparément: pré-tension, règlage de la tension, mise en mouvement permettant le secouage de la branche, arrêt du secouage et enroulement de l'agent de secouage, il est aisé d'appliquer à chacune des branches sollicitées le secouage optimum en durée et en intensité. In addition, each shaking agent being controlled separately: pre-tensioning, adjusting the tension, setting in motion allowing the shaking of the branch, stopping the shaking and winding of the shaking agent, it is easy to apply to each branches requested optimum shaking in duration and intensity.
Selon une réalisation, le dispositif objet de l'invention, chaque secoueur, illustré par la figure 1, comporte essentiellement un câble (a) dont une extrémité (b) est enroulée sur une bobine-magasin (c) et passant par un dispositif (d) animé d'un mouvement de rotation ou de va et vient, puis par un guide (e). L'extrémité libre du câble est munie d'un accessoire quelconque (f) destiné à permettre son accrochage sur les branches à secouer. Un renvoi (g) peut en outre être disposé entre la bobine-magasin et le dispositif (d) ou entre le dispositif (d) et le guide (e) de manière à modifier l'amplitude du mouvement de l'extrémité libre de chaque câble par simple déplacement de la position de ce renvoi (g). According to one embodiment, the device which is the subject of the invention, each shaker, illustrated by FIG. 1, essentially comprises a cable (a) one end of which (b) is wound on a magazine reel (c) and passing through a device ( d) animated by a rotation or back and forth movement, then by a guide (e). The free end of the cable is provided with any accessory (f) intended to allow it to be hooked on the branches to be shaken. A reference (g) can also be arranged between the reel-magazine and the device (d) or between the device (d) and the guide (e) so as to modify the amplitude of movement of the free end of each cable by simply moving the position of this reference (g).
La bobine-magasin est équipée de dispositifs comportant un système d'entraînement par friction destiné à assurer l'enroulement automatique du câble et la pré-tension avant secouage, ainsi qu'un système d'enroulement forcé du câble avec blocage de la poulie quand la tension désirée est atteinte, et libération de la bobine-magasin quand le secouage est terminé. The reel-magazine is equipped with devices comprising a friction drive system intended to ensure automatic cable winding and pre-tensioning before shaking, as well as a forced cable winding system with blocking of the pulley when the desired tension is reached, and release of the reel-magazine when the shaking is finished.
Selon une réalisation, le dispositif d'enroulement automatique, sur les bobines-magasin, illustré par la figure 2 comporte essentiellement, un arbre d'entrainement (h) sur lequel tournent librement les bobines-magasins (c), des manchons (i) solidaires de l'arbre d'entraînement, un élément d'entraînement par friction (j) placé entre chaque bobine-magasin et chaque manchon(i), des ressorts (k) assurant le serrage des éléments d'entraînement entre les bobines-magasins et les manchons (i). According to one embodiment, the automatic winding device, on the reels-magazine, illustrated by FIG. 2 essentially comprises, a drive shaft (h) on which the reels-magazine (c) freely rotate, sleeves (i) integral with the drive shaft, a friction drive element (j) placed between each reel-magazine and each sleeve (i), springs (k) ensuring the tightening of the drive elements between the reels-magazine and the sleeves (i).
Le dispositif d'enroulement forcé du câble, de blocage et de libération de chaque bobine est, selon une réalisation illustrée par la figure 1 composé essentiellement par : une couronne dentée (1), solidaire de chaque bobine-magasin (c), un cliquet de retenue (ou de blocage) (m) pivotant sur un axe (n), un levier de commande (o) pivotant sur son axe (p) et un cliquet d'entraînement (q) pivotant sur son axe (r) situé sur le levier de commande (o) et un accessoire (s) assurant directement ou indirectement la liaison entre le cliquet de retenue (m) et le levier de commande (o). The device for forced winding of the cable, for blocking and releasing each reel is, according to an embodiment illustrated in FIG. 1, essentially composed of: a toothed crown (1), integral with each reel-magazine (c), a pawl retaining (or locking) (m) pivoting on an axis (n), a control lever (o) pivoting on its axis (p) and a drive pawl (q) pivoting on its axis (r) located on the control lever (o) and an accessory (s) directly or indirectly ensuring the connection between the retaining pawl (m) and the control lever (o).
Grâce à ce dispositif particulier, le levier de commande (o) permet d'assurer la tension forcée du câble ainsi que la libération de la bobine-magasin. En effet en imprimant au levier un mouvement de va et vient il entraîne le cliquet (q) dans un mouvement de translation entraînant la rotation de la roue dentée (1) solidaire de la bobine-magasin. Pendant les retours à vide du cliquet (q) ou quand le levier (o) est immobile, le cliquet (m) immobilise la couronne dentée (1). Pour libérer la couronne dentée (1) et donc la bobine-magasin,il convient d'agir sur le levier de commande (o) qui, en fin de course et grâce à l'accessoire (s), soulève le cliquet de retenue (m) qui soulève à son tour le cliquet d'entraînement (q). Thanks to this particular device, the control lever (o) ensures the forced tension of the cable as well as the release of the reel-magazine. Indeed by printing the lever back and forth it drives the pawl (q) in a translational movement causing the rotation of the toothed wheel (1) integral with the reel-magazine. During the empty returns of the pawl (q) or when the lever (o) is stationary, the pawl (m) immobilizes the toothed crown (1). To release the ring gear (1) and therefore the reel-magazine, it is necessary to act on the control lever (o) which, at the end of the stroke and thanks to the accessory (s), lifts the retaining pawl ( m) which in turn lifts the drive pawl (q).
