Abstract

The present invention describes a device for harvesting corn, especially made up in the shape of an additional device for a self-propelled combine harvester, comprising an insertion device and a harvesting gap for separating the ears from the plants, the harvesting device comprising, for each row of plants, an insertion chain and a harvesting cylinder, with which a partial casing is associated and which is essentially constituted by an element of cylindrical base on the casing of which there are arranged, at regular intervals, drive plates and in which a dividing point in the shape of a conical frustrum equipped with an archimedes screw made from sheet metal is firmly connected to the front part, viewed in the direction of forward travel, of the base element. In order to ensure a perfect and even flow of the products and to reduce the energy necessary for operating the machine as far as possible, another dividing point 26 is combined with the dividing point 11 of the insertion cylinder 4, whilst a rotary circular cutter 22 or chopper with additional balance arms 28 which cuts up the stalks a little above ground level is provided at the rear, viewed in the direction of forward travel, of this additional dividing point 26.

Description

Dispositif pour la moisson de maIs. Device for harvesting corn.

L'invention concerne un dispositif pour la moisson de maIs ou autres céréales, constitué notamment sous forme d'un dispositif auxiliaire pour une moissonneuse-batteuse automotrice, comprenant un dispositif d'introduction et un interstice de cueillette pour séparer les épis des plants, le dispositif de moisson comprenant pour chaque rangée de plants une chaste d'introduction et un cylindre de cueillette, auquel est associée une enveloppe partielle et qui est constitué essentiellement par un élément de base cylindrique sur l'enveloppe duquel sont disposées, à intervalles réguliers, des plaques d'entrainement et dans lequel une pointe diviseuse en forme de tronc de cône équipée d'une vis sans fin en tôle est fermement reliée à la partie avant, vue dans le sens de la marche, de l'élément de base. The invention relates to a device for harvesting corn or other cereals, constituted in particular in the form of an auxiliary device for a self-propelled combine, comprising an introduction device and a picking gap to separate the ears of plants from the plants, the harvesting device comprising for each row of plants an introductory chaste and a picking cylinder, with which is associated a partial envelope and which consists essentially of a cylindrical base element on the envelope of which are arranged, at regular intervals, drive plates and in which a dividing point in the form of a truncated cone equipped with a sheet metal endless screw is firmly connected to the front part, seen in the direction of travel, of the basic element.

Un dispositif de moisson de ce type est connu par exemple par la demande de brevet européen No 0 091 635. Dans ce cas, et en dehors de la cueillette proprement dite des épis, a lieu simultanément le hachage des tiges. Mais du fait que pour des raisons constructives la channe d'introduction et le cylindre cueilleur sont décalés l'un par rapport à l'autre en hauteur, il résulte que les tiges individuelles ne sont pas toujours correctement introduites dans l'interstice de cueillette et qu'elles s'accumulent à l'avant de celui-ci. Pour assurer un fonctionnement fiable, il faut donc d'une part que la puissance d'entratnement de la machine soit très élevée et d'autre part que les parties individuelles soient de constitution très résistante et robuste. A harvesting device of this type is known for example from European patent application No. 0 091 635. In this case, and apart from the actual picking of the cobs, the chopping of the stems takes place simultaneously. However, owing to the fact that, for constructive reasons, the insertion channel and the picking cylinder are offset relative to each other in height, it follows that the individual rods are not always correctly introduced into the picking gap and that they accumulate at the front of it. To ensure reliable operation, it is therefore necessary on the one hand that the drive power of the machine is very high and on the other hand that the individual parts are of very resistant and robust constitution.

La présente invention a donc pour point de départ le problème consistant à réduire la puissance d'entrainement de la machine du type mentionné dans le préambule et d'assurer un débit régulier. The present invention therefore has as its starting point the problem consisting in reducing the driving power of the machine of the type mentioned in the preamble and in ensuring a regular flow.

Selon l'invention, ce but est atteint du fait qu'à la pointe diviseuse du cylindre cueilleur est associée une pointe diviseuse additionnelle et entrainable, dont l'axe est parallèle à l'axe du cylindre cueilleur. According to the invention, this object is achieved due to the fact that the dividing tip of the picking cylinder is associated with an additional and drivable dividing tip, the axis of which is parallel to the axis of the picking cylinder.

Selon une autre caractéristique de l'invention, un couteau circulaire et rotatif est monté, vu dans le sens de la marche, à l'arrière de la pointe diviseuse additionnelle, sa région de coupe active étant située au-dessous du cylindre cueilleur. D'autres formes de réalisation avantageuses de l'invention sont indiquées dans les sous-revendications.According to another characteristic of the invention, a circular and rotary knife is mounted, seen in the direction of travel, behind the additional dividing tip, its active cutting region being located below the picking cylinder. Other advantageous embodiments of the invention are indicated in the dependent claims.

L'invention va maintenant être décrite plus en détail dans ce qui suit en se référant à un mode de réalisation et aux diverses figures qui le représentent schématiquement. Sur le dessin:
la figure 1 représente un dispositif de moisson de mals vu latéralement,
la figure 2 est une vue en plan d'une partie du dispositif de moisson représenté à la figure 1, et
la figure 3 est une vue en coupe selon la ligne III-III de la figure 1.
The invention will now be described in more detail in what follows with reference to an embodiment and to the various figures which represent it diagrammatically. On the drawing:
FIG. 1 represents a device for harvesting males viewed laterally,
FIG. 2 is a plan view of a part of the harvesting device shown in FIG. 1, and
Figure 3 is a sectional view along line III-III of Figure 1.

En 1 est désigné un dispositif de moisson de mais connu en soi, constitué par deux diviseurs 2, respectivement pour chaque rangée à moissonner. A ces deux diviseurs se raccordent des tôles de guidage 3 et ils sont associés à un cylindre d'introduction et de cueillette 4. In 1 is designated a harvesting device but known per se, consisting of two dividers 2, respectively for each row to be harvested. Guide plates 3 are connected to these two dividers and they are associated with an introduction and picking cylinder 4.

Les épis de mais qui sont séparés des tiges parviennent sur une vis transporteuse transversale 5 et de là à un transporteur incliné 6, pour parvenir par exemple dans un récipient collecteur ou dans un dispositif de battage. Le montage d'une chaste d'introduction 7 est montré aux figures 2 et 3, channe au moyen de laquelle les tiges sont introduites dans l'interstice de cueillette en position verticale alors que les épis séparés sont envoyés vers la vis transporteuse transversale 5.The ears of corn which are separated from the stems reach a transverse conveyor screw 5 and from there to an inclined conveyor 6, to arrive for example in a collecting container or in a threshing device. The assembly of an introduction chaste 7 is shown in FIGS. 2 and 3, channe by means of which the stems are introduced into the picking gap in a vertical position while the separate ears are sent to the transverse conveyor screw 5.

L'interstice de cueillette est limité sur un côté par une tôle de guidage réglable 9 et sur l'autre côté par un fer rond 10 faisant fonction de rebord de sectionnement. Au-dessous de la tôle de guidage 9, le cylindre d'introduction 4 est monté de façon à pouvoir être entratné et il est entouré en partie par une enveloppe partielle 12.The picking gap is limited on one side by an adjustable guide plate 9 and on the other side by a round iron 10 acting as a cutting edge. Below the guide plate 9, the introduction cylinder 4 is mounted so that it can be driven and it is partially surrounded by a partial envelope 12.

Cette enveloppe partielle 12 se raccorde au fer rond 10 vers le bas et est reliée d'un seul tenant ou de facon articulée à ce dernier. Le cylindre d'introduction 4 est constitué sous forme d'un élément cylindrique 13 comprenant une pointe d'introduction 11 en forme de tronc de cône et munie d'une vis sans fin 14, des plaques d'entralnement 16 étant disposées sur l'enveloppe 15 de l'élément 13 et munies de découpes 17. Dans ces découpes 17 pénètre un soc à couteaux 18 dont les couteaux individuels sont fixés à un porte-couteau 19. Le porte-couteau 19 est lui-même vissé sur une traverse 20. Pour assurer un sectionnement total des tiges par la coopération du cylindre d'introduction et du soc à couteaux, l'enveloppe de l'élément de base 13 comprend des gorges périphériques 29 dans lesquelles pénètrent les tranchants libres 21 des couteaux.Comme le montre la figure 3, un couteau circulaire et rotatif 22 est prévu au-dessous du soc à couteaux 18 dans un plan sensiblement horizontal, au moyen duquel les tiges sont sectionnées un peu au-dessus du niveau du sol, ce qui facilite l'avance de la machine. L'axe 23 du couteau circulaire 22 est monté sur un côté dans une botte à engrenages 24 et est en prise par des pignons de renvoi avec un arbre d'entratnement 25 dont l'extrémité, vue dans le sens de la marche, supporte une pointe diviseuse 26 en forme de tronc de cône et équipée d 'une vis sans fin 27. La pointe diviseuse 26 est parallèle et située dans le même plan horizontal que la pointe diviseuse 11, ce qui fait que les tiges sont introduites parfaitement dans l'interstice de cueillette. A la place du couteau circulaire 22 représenté à la figure 3, on peut prévoir, comme indiqué à la figure 2, un hacheur à fléaux 28, plusieurs fléaux pouvant être disposés les uns au-dessus des autres. Dans un tel mode de réalisation, on peut éviter l'utilisation du soc à couteaux 18 This partial envelope 12 is connected to the round iron 10 downwards and is connected in one piece or in an articulated manner to the latter. The introduction cylinder 4 is constituted in the form of a cylindrical element 13 comprising an introduction point 11 in the form of a truncated cone and provided with an endless screw 14, entrainment plates 16 being arranged on the casing 15 of the element 13 and provided with cutouts 17. In these cutouts 17 penetrates a knife share 18 whose individual knives are fixed to a knife holder 19. The knife holder 19 is itself screwed onto a crosspiece 20 To ensure total cutting of the rods by the cooperation of the insertion cylinder and the knife blade, the casing of the base element 13 includes peripheral grooves 29 into which the free cutting edges 21 of the knives penetrate. Figure 3, a circular and rotary knife 22 is provided below the knife blade 18 in a substantially horizontal plane, by means of which the rods are cut a little above ground level, which facilitates the advance of the machine. The axis 23 of the circular knife 22 is mounted on one side in a gear boot 24 and is engaged by idler gears with a drive shaft 25 whose end, seen in the direction of travel, supports a dividing point 26 in the shape of a truncated cone and equipped with an endless screw 27. The dividing point 26 is parallel and situated in the same horizontal plane as the dividing point 11, so that the rods are introduced perfectly into the picking gap. Instead of the circular knife 22 shown in Figure 3, one can provide, as shown in Figure 2, a flail chopper 28, several flails can be arranged one above the other. In such an embodiment, the use of the knife blade 18 can be avoided.
