Abstract

The present invention relates to an extracting device for articles made of delicate and/or crumbly material, such as seedlings comprising crumbly lumps of earth, held in cells constituted by holes pierced right through in a plate forming a support. This device is characterised in that each push rod 5 is extended at its end by at least one thin pin 8 which extends essentially longitudinally and is intended to engage in the inside of the article, before the front face 5a of the push rod comes into contact with the facing face of the article, so that each article 1, disengaged from its cell 3, is held in position on the end of the push rod 5, as a result of the penetration of the pin 8 of the latter inside the article 1.

Description

La présente invention concerne un dispositif ex trac-
teur d'articles en matière tendre et/ou friable, tels que
des plants comportant des mottes de terre ou autre, maintenus dans des alvéoles constitués par des trous percés de part en part dans un plateau formant support.
The present invention relates to an ex trac-
of articles made of soft and / or brittle material, such as
plants comprising clods of earth or other, held in cells formed by holes drilled right through in a tray forming a support.

Dans de nombreux domaines et notamment en agricul
ture il est nécessaire de pouvoir extraire des articles en matibre tendre, tels que des plants comprenant des mottes de terre friables ou autre, de plateaux supports, afin de pouvoir reprendre ces articles, d'une manière précise, en vue de leur transfert en direction de leur zone d'utilisation.
In many fields and in particular in agricul
ture it is necessary to be able to extract articles in soft material, such as plants comprising clods of friable earth or other, from support trays, in order to be able to retrieve these articles, in a precise manner, for their transfer towards of their area of use.

Par exemple, dans le cas de plants, ceux-ci, une fois extraits des alvéoles de leur support, doivent être pris par des moyens de transport pour être ensuite plantés en terre.For example, in the case of plants, these, once extracted from the cells of their support, must be taken by means of transport and then planted in the ground.

On connait déja, dans le cas des plants, une machine qui assure l'extraction automatique des plants de leurs alvéoles respectifs, ces plants étant ensuite repris par des moyens de transport pour pouvoir être plantés en terre. Dans une telle machine connue les moyens d'extraction sont constitués par des poussoirs associés aux alvéoles respectifs, s'étendant sensiblement dans l'axe de ces divers alvéoles et tant animés d'un mouvement alternatif qui permet de les engager axialement dans les alvéoles, afin d'éjecter les plans hors de ceux-ci, et de les retirer ensuite des alvéoles en vue d'un cycle de fonctionnement suivant.Un tel dispositif connu présente toutefois l'inconvénient que les plants éjectés de leurs alvéoles se trouvent être totalement libérés une fois sortis de ceux-ci, ce qui ne permet pas de les reprendre d'une manière positive et précise en vue de leur transport vers la zone d'utilisation, pour pouvoir être plantés en terre. We already know, in the case of plants, a machine which ensures the automatic extraction of plants from their respective cells, these plants are then taken up by means of transport to be able to be planted in the ground. In such a known machine, the extraction means consist of pushers associated with the respective cells, extending substantially in the axis of these various cells and both driven by an alternating movement which makes it possible to engage them axially in the cells, in order to eject the planes out of them, and then withdraw them from the alveoli for a next operating cycle. Such a known device however has the drawback that the plants ejected from their alveoli are found to be completely released once out of them, which does not allow them to be taken up in a positive and precise manner with a view to their transport to the area of use, so that they can be planted in the ground.

La présente invention vise à remédier à cet inconvénient en procurant un dispositif de conception particulièrement simple permettant d'obtenir, à la sortie de chaque alvéole, un maintien ferme et précis des divers articles. The present invention aims to remedy this drawback by providing a device of particularly simple design making it possible to obtain, at the outlet of each cell, a firm and precise hold of the various articles.

A cet effet ce dispositif extracteur d'articles en matière tendre et/ou friable, tels que des plants comportant des mottes de terre friables ou autre, maintenus dans des alvéoles constitués par des trous percés de part en part dans un plateau formant support, comportant, d'un cOté du plateau, des poussoirs disposés respectivement en regard des alvéoles, sensiblement dans les axes de ceux-ci, des moyens pour déplacer simultanément et alternativement tous les poussoirs pour les engager dans les alvéoles afin de repousser les articles, hors de ces alvéoles, et, du côté opposé du plateau, des moyens de reprise des articles dégagés de leurs alvéoles, est caractérisé en ce que chaque poussoir est prolongé, à son extrémité, par au moins une fine broche s'étendant sensiblement longitudinalement et destinée à s'engager à l'intérieur de l'article, avant que la face frontale du poussoir ne vienne en contact avec la faee en reqard de l'article, si bien que chaque article dégagé de son alvéole se trouve être maintenu en position sur l'extrémité du poussoir, par suite de la pénétration de la broche de celui-ci à l'intérieur de l'article. To this end, this device for extracting articles of soft and / or friable material, such as plants comprising friable clods of earth or the like, held in cells formed by holes drilled right through in a tray forming a support, comprising , on one side of the tray, pushers arranged respectively opposite the cells, substantially in the axes thereof, means for simultaneously and alternately moving all the pushers to engage them in the cells in order to push the articles out of these cells, and, on the opposite side of the plate, means for taking up the articles released from their cells, is characterized in that each pusher is extended, at its end, by at least one thin pin extending substantially longitudinally and intended to engage inside the article, before the front face of the pusher comes into contact with the faee in relation to the article, so that each article released from its socket is found to be held in position on the end of the pusher, as a result of the pin's penetration inside the article.

Le dispositif suivant l'inveniton offre l'avantage que chaque article extrait d'un alvéole se trouve maintenu dans une position bien déterminée dans l'espace, ce qui permet de saisir cet article par des moyens de transport tels que des pinces. The device according to the invention offers the advantage that each article extracted from a cell is kept in a well-defined position in space, which makes it possible to grasp this article by means of transport such as tongs.

On décrira ci-après,à titre d'exemple non limitatif, une forme d'exécution de la présente invention,en référence au dessin annexé sur lequel
La figure 1 est une vue en élévation schématique d'un dispositif extracteur de plants suivant l'invention, en position de départ d'un cycle d'extraction.
An embodiment of the present invention will be described below, by way of non-limiting example, with reference to the attached drawing in which
Figure 1 is a schematic elevational view of a plant extractor device according to the invention, in the starting position of an extraction cycle.

Les figures 2, 3 et 4 sont des vues en élévation schématique du dispositif extracteur au cours de phases successives du cycle d'extraction. Figures 2, 3 and 4 are schematic elevational views of the extractor device during successive phases of the extraction cycle.

Le dispositif extracteur suivant l'invention qui est représenté sur la figure 1 est destiné à extraire des plants 1, comportant chacun une motte de terre friableou autre 2 dans laquelle se sont développées les racines, d'al véroles 3 prévus régulièrement dans un plateau formant support 4. Les alvéoles 3 sont constitués par des trous percés de part en part dans le plateau 4, ces trous ayant de préf6- rence une forme tronconique dont la qrande base est tournée vers le haut, c'est-à-dire du côté de la sortie des plants 1. The extractor device according to the invention which is shown in FIG. 1 is intended for extracting plants 1, each comprising a clod of friable or other soil 2 in which the roots have grown, of smallpox 3 regularly provided in a tray forming support 4. The cells 3 are constituted by holes drilled right through in the plate 4, these holes preferably having a frustoconical shape whose qrande base is turned upwards, that is to say on the side from the exit of the plants 1.

Le dispositif extracteur comprend un ensemble de poussoirs 5 constitués par des tiges 5 s'étendant verticalement, respectivement suivant les axes des divers alvéoles 3. Les divers poussoirs verticaux 5 sont déplacés simultanément et alternativement dans le sens vertical, au moyen d'un mécanisme de tout type approprié, ce mécanisme comportant par exemple un vérin 6 d'axe vertical et dont la tige de piston est solidaire d'une embase horizontale 7 sur laquelle sont fixés tous les poussoirs 5. The extractor device comprises a set of pushers 5 constituted by rods 5 extending vertically, respectively along the axes of the various cells 3. The various vertical pushers 5 are moved simultaneously and alternately in the vertical direction, by means of a mechanism any suitable type, this mechanism comprising for example a jack 6 with a vertical axis and the piston rod of which is integral with a horizontal base 7 on which all the pushers 5 are fixed.

Suivant l'invention chaque poussoir 5 est solidai-re d'au moins une broche fine 8 s'étendant longitudinalement- et qui est issue de la face frontale supérieure 5a du poussoir. According to the invention each pusher 5 is solidai-re of at least one thin pin 8 extending longitudinally- and which is from the upper front face 5a of the pusher.

La longueur de chaque broche 8 est choisie de manière à être un peu inférieure à la hauteur de la motte de terre tronconique 2 du plant I devant être extrait. Le poussoir 5 peut être solidaire d'une seule broche 8 s'étendant axialement comme il est représenté sur le dessin, ou encore de plusieurs broches parallèles à l'axe du poussoir, convergentes ou encore diverqentes. The length of each spindle 8 is chosen so as to be a little less than the height of the frustoconical clod of earth 2 of the plant I to be extracted. The pusher 5 may be integral with a single pin 8 extending axially as shown in the drawing, or also with several pins parallel to the axis of the pusher, convergent or even divergent.

En position de départ du cycle d'extraction, tous les poussoirs 5 se trouvent en position basse, comme il est représenté sur la figure 1, les broches 8 se trouvant un peu en dessous des mottes 2 des plants 1, dans l'axe de ces mottes. Lorsque le vérin 6 est alimenté par le fond, la tige de piston de ce vérin s'élève en entraînant avec elle tous les poussoirs 5 et les broches 8. A un certain moment chaque broche 8 pénètre dans la face inférieure de la motte 2 en regard de laquelle elle se trouve, puis axialement à l'intérieur de cette motte jusqu' ce que la face frontale sur rieure 5a du poussoir 5 vienne en contact avec la face inférieure de la motte 2. Ceci correspond à la position illustrée sur la figure 2.A partir de ce moment la poursuite du mouvement des poussoirs 5 vers le haut provoque une sortie progressive des mottes 2 des plants 1 hors de leurs alvéoles respectifs 3. Durant ce mouvement de sortie chaque motte 2 est maintenue fermement sur la face frontale sur rieure 5a du poussoir associé 5, grâce à la prévision de la broche 8 qui se trouve être enfoncée axialement à l'int- rieur de la motte comme on peut le voir sur la figure 3. En fin de cycle de montée des poussoirs 5, les plants 1 se trouvent être totalement dégagés des alvéoles 3 du plateau support 4, au-dessus de celui-ci, et ils sont maintenus, par les broches 8, dans des positions bien déterminées.Ceci permet de saisir chacun des plants 1, par exemple au moyen d'une pince 9 dont les deux mâchoires opposées viennent serrer entre elles la motte de terre 2. Une fois les mottes 2 des plants 1 saisies par les pinces 9, l'ensemble des poussoirs 5 est amené à redescendre, gracie à l'alîmentaiton du vérin 6 par le nez. De ce fait les poussoirs 5 s'écartent des mottes 2 et les broches 8 se dégagent progressivement de l'intérieur de ces mottes. Ces mottes demeurent alors saisies entre les mâchoires des diverses pinces 9 et eles peuvent être transférées alors vers la zone d'utilisation. In the starting position of the extraction cycle, all of the pushers 5 are in the low position, as shown in FIG. 1, the pins 8 being located a little below the clods 2 of the plants 1, in the axis of these clods. When the jack 6 is fed from the bottom, the piston rod of this jack rises, carrying with it all the pushers 5 and the pins 8. At a certain moment each pin 8 enters the underside of the root ball 2 in look of which it is, then axially inside this clod until the front face on the upper 5a of the pusher 5 comes into contact with the underside of the clod 2. This corresponds to the position illustrated in the figure 2. From this moment the continuation of the movement of the pushers 5 upwards causes a gradual exit of the clods 2 of the plants 1 out of their respective cells 3. During this outward movement each clod 2 is held firmly on the front face on lower 5a of the associated pusher 5, by virtue of the provision of the spindle 8 which happens to be driven axially inside the root ball as can be seen in FIG. 3. At the end of the rise cycle of the pusher 5, plants 1 happen to be early alement cleared from the cells 3 of the support plate 4, above it, and they are maintained, by the pins 8, in well determined positions. This allows each of the plants 1 to be gripped, for example by means of a pliers 9, the two opposite jaws of which clamp the clod of earth between them 2. Once the clods 2 of the plants 1 are gripped by the pliers 9, all of the pushers 5 are brought down, thanks to the feeding of the jack 6 through the nose. As a result, the pushers 5 move away from the clods 2 and the pins 8 gradually disengage from the interior of these clods. These lumps then remain seized between the jaws of the various clamps 9 and they can then be transferred to the area of use.

Enfin de cycle de retour les poussoirs 5 se retrouvent en position de départ basse figure 4) oti ils sont prêts pour un nouveau cycle d'extraction. Le plateau support 4 se trouve alors totalement vidé des plants 1. Finally, in the return cycle, the pushers 5 are found in the lower starting position (FIG. 4) or they are ready for a new extraction cycle. The support plate 4 is then completely emptied of the plants 1.
