Description

DESCRIPTION DESCRIPTION

La présente invention concerne un dispositif pour planter des plants de forme quasi 5 sphérique de façon bien orientée, c'est-à-dire avec le plateau racinaire en bas et le collet en haut. Actuellement, les plants comme par exemple les bulbes d'oignon destinés à la production de semences sont distribués au sol à la machine dans un sillon. Les plants sont alors orientés de façon aléatoire car leur forme est pratiquement sphérique. II est alors 10 nécessaire de les redresser, opération consistant à les orienter manuellement de telle sorte que le plateau racinaire soit en dessous dans le but que la plante puisse croître normalement, avec les racines en bas et la future tige en haut. Cette opération de redressement est manuelle, et préalable au buttage de terre qui est mécanisé. Le plant peut alors entamer sa croissance. L'opération de plantation se fait donc en 3 phases distinctes et 15 séparées: répartition des bulbes dans le sillon, redressement manuel, buttage. L'opération de plantation est longue, à une période de l'année où la météorologie est aléatoire rendant les conditions de travail pénibles. Le dispositif selon l'invention permet de mécaniser l'opération de redressement. Il se compose de 2 goulottes positionnées en bout à bout, formant un angle entre elles, 20 l'ensemble étant légèrement incliné par rapport à l'horizontale et animé d'un mouvement de va et vient proche de l'horizontale, dans le grand axe des guides. La goulotte secondaire est davantage inclinée que la goulotte primaire. Les plants sont alimentés en amont sur la goulotte primaire qui les aligne en les faisant glisser vers le bas en direction de la goulotte secondaire par le mouvement de va et vient. Les plants arrivent alors sur la goulotte 25 secondaire dont l'inclinaison par rapport à l'horizontale est plus forte, ce qui les fait rouler sur eux même jusqu'à ce que ce roulage soit interrompu au moment où le collet du bulbe, en forme de pointe tronconique proéminente et diamétralement opposée au plateau racinaire, touche le fond de la goulotte. A ce stade les plants ont tous la même orientation et glissent alors jusqu'à l'extrémité de la goulotte secondaire, avec le plateau racinaire orienté vers le 30 haut. Enfin, les plants tombent de la seconde goulotte, dont l'extrémité comporte un détail de forme, ce qui déclenche lors de sa chute un mouvement de rotation du plant autour d'un axe horizontal passant par le centre de gravité du plant et perpendiculaire au grand axe des guides. La hauteur de chute est réglée de telle manière que la rotation soit d'un peu plus d'un demi-tour, ce qui fait que les plants tombent au sol dans le sillon avec le plateau 35 racinaire en bas, bien orienté. The present invention relates to a device for planting seedlings of nearly spherical shape in a well oriented manner, that is with the root plate at the bottom and the neck at the top. Currently, seedlings such as onion bulbs for seed production are machine-grounded in a groove. The plants are then oriented randomly because their shape is practically spherical. It is then necessary to straighten them, the operation of manually orienting them so that the root plate is below in order that the plant can grow normally, with the roots down and the future stem up. This straightening operation is manual, and prior to ridging earth is mechanized. The plant can then begin to grow. The planting operation is therefore done in 3 distinct and separate phases: distribution of the bulbs in the furrow, manual recovery, ridging. The planting operation is long, at a time of year when the weather is random making the working conditions difficult. The device according to the invention makes it possible to mechanize the straightening operation. It consists of two chutes positioned end-to-end, forming an angle between them, the whole being slightly inclined with respect to the horizontal and moving with a movement back and forth close to the horizontal, in the large axis of the guides. The secondary chute is more inclined than the primary chute. The plants are fed upstream on the primary chute which aligns them by sliding them down towards the secondary chute by the movement back and forth. The plants then arrive on the secondary chute whose inclination with respect to the horizontal is stronger, which makes them roll on themselves until this rolling is interrupted at the moment when the collar of the bulb, shaped prominent frustoconical point and diametrically opposed to the root plate, touches the bottom of the chute. At this stage the seedlings all have the same orientation and then slide to the end of the secondary chute with the root tray facing upwards. Finally, the plants fall from the second chute, whose end has a shape detail, which triggers during its fall a rotational movement of the plant around a horizontal axis passing through the center of gravity of the plant and perpendicular to the major axis of the guides. The drop height is set so that the rotation is a little more than half a turn, so that the plants fall to the ground in the furrow with the root plate down well oriented.

Pour un fonctionnement optimal et notamment pour s'adapter au type de plant, à l'hygrométrie ambiante et au dénivelé du terrain, différents réglages sont possibles : la forme de la section de chacune des 2 goulottes, l'angle d'inclinaison générale, l'angle entre les goulottes primaires et secondaires, l'amplitude du mouvement de va et vient, la fréquence de ce mouvement. Les dessins annexés illustrent l'invention: La figure 1 représente le dispositif de l'invention de face. La figure 2 représente le dispositif de l'invention de profil. For optimal operation and in particular to adapt to the type of plant, the ambient humidity and the unevenness of the ground, various adjustments are possible: the shape of the section of each of the 2 chutes, the general angle of inclination, the angle between the primary and secondary chutes, the amplitude of the movement back and forth, the frequency of this movement. The accompanying drawings illustrate the invention: FIG. 1 represents the device of the invention from the front. Figure 2 shows the device of the invention in profile.

En référence à ces dessins, le dispositif comporte une goulotte primaire (1), en forme de réceptacle de plants alimentés en zone (3). Le mouvement de va et vient (W) fait avancer les plants dans le fond des 2 goulottes (1) et (2) de la zone (3) vers la zone (6). La zone (4) est la zone d'alignement des plants qui vont pivoter en zone (5) jusqu'à ce que le collet touche le fond de la goulotte secondaire (2). Ensuite les plants vont glisser vers le bas en zone (6), pour finalement chuter en tournant sur eux même grâce au détail de forme (7). Selon des modes particuliers de réalisation : - les 2 goulottes (1) et (2) sont soudées selon un angle fixe. - l'inclinaison (a) des 2 goulottes est réglable pour compenser les pentes du terrain - les 2 goulottes (1) et (2) sont articulées de telle sorte que l'angle (b) soit réglable 20 -l'inclinaison (a) des 2 goulottes est réglable pour compenser les pentes du terrain. - le mouvement de va et vient (W) est assuré par un système de bielle manivelle, dont la fréquence et l'amplitude sont réglables. - la fixation des 2 goulottes (1) et (2) est assurée par des leviers oscillants à mouvement circulaires autour d'une position médiane réglable légèrement incliné par rapport à la 25 verticale. Le dispositif selon l'invention est particulièrement destiné à la plantation de bulbes d'oignon porte graines. Il peut être monté sur une planteuse, qui comporte traditionnellement une trémie, des traceurs de sillons, un dispositif de dosage et de répartition au sol. Le dispositif selon l'invention est monté en aval du dispositif de dosage qui l'alimente, et assure 30 la répartition dans le sillon des bulbes qui alors sont bien orientés. En aval, il est possible de monter un dispositif de buttage sur la planteuse. Ainsi, le dispositif selon l'invention permet la plantation des bulbes en 1 seul passage là où il en avait 3 : répartition des bulbes dans le sillon, redressement manuel, buttage. With reference to these drawings, the device comprises a primary chute (1) in the form of a receptacle for plants fed in zone (3). The movement back and forth (W) advances the plants in the bottom of the 2 troughs (1) and (2) of the zone (3) to the zone (6). The zone (4) is the alignment zone of the plants that will pivot in zone (5) until the collar touches the bottom of the secondary chute (2). Then the plants will slide down in zone (6), to finally fall while turning on themselves thanks to the detail of form (7). According to particular embodiments: - the 2 chutes (1) and (2) are welded at a fixed angle. - The inclination (a) of the 2 chutes is adjustable to compensate for the slopes of the ground - the 2 chutes (1) and (2) are articulated so that the angle (b) is adjustable 20 -the inclination (a ) 2 chutes is adjustable to compensate for the slopes of the ground. - The movement back and forth (W) is provided by a crank system, whose frequency and amplitude are adjustable. the fixing of the two troughs (1) and (2) is ensured by oscillating levers with circular movement around a median position adjustable slightly inclined with respect to the vertical. The device according to the invention is particularly intended for planting seed onion bulbs. It can be mounted on a planter, which traditionally comprises a hopper, tracer tracers, a device for dosing and distribution on the ground. The device according to the invention is mounted downstream of the metering device which feeds it, and ensures the distribution in the furrow of the bulbs which are then well oriented. Downstream, it is possible to mount a ridging device on the planter. Thus, the device according to the invention allows the planting of bulbs in a single pass where it had 3: distribution of bulbs in the groove, manual rectification, ridging.
