Description

Ramasseuse-hacheuse pour produits de récolte agricoles. Chopper for agricultural harvesting products.

L'invention concerne une ramasseuse-hacheuse pour produits de recolte agricoles, comprenant un dispositif recepteur de produits prevu à son extremite avant, un ensemble hacheur et une paire de cylindres de conditionnement entratnes et associes à cet ensemble, les cylindres étant constitués chacun par une enveloppe cylindrique éventuellement dentée sur sa périphérie extérieure et par des couvercles de fermeture frontaux à tourillons de support associés. The invention relates to a chopper for agricultural harvesting products, comprising a product receiving device provided at its front end, a chopper assembly and a pair of conditioning cylinders driven and associated with this assembly, the cylinders each being constituted by a cylindrical casing possibly toothed on its outer periphery and by front closure covers with associated support pins.

Dans les ramasseuse-hacheuses connues jusqu'ici, les couvercles de fermeture sont munis de tourillons de support soudés fermement sur leur côté frontal à l'enveloppe du cylindre. Ceci a tout d'abord pour conséquence qu'il faut remplacer la totalité du cylindre lorsque son enveloppe est usée. Par ailleurs, l'enveloppe du cylindre se voile lors du soudage du couvercle de fermeture de façon telle qu'il faut avoir recours à un travail additionnel pour rectifier l'enveloppe du cylindre denté et durci et obtenir un effet de conditionnement régulier sur la totalité de la longueur du cylindre. Comme l'enveloppe durcie est en partie enlevée par 11 opération de rectification additionnelle, les cylindres ainsi traités sont sujets à une usure importante.La présente invention a donc pour but de proposer une ramasseuse-hacheuse du type indiqué dans le préambule dans laquelle les cylindres n'ont pas besoin d'être remplacés dans leur ensemble en cas d'usure. Selon l'invention, ce but est atteint du fait que l'enveloppe du cylindre et les deux couvercles de fermeture sont serrés les uns contre les autres de façon amovible et centrée par une tige de traction qui traverse centralement les couvercles et les tourillons de support associés. In the previously known chopper harvesters, the closing covers are provided with support pins welded firmly on their front side to the cylinder casing. This has the first consequence that it is necessary to replace the entire cylinder when its envelope is worn. In addition, the cylinder envelope becomes veiled during welding of the closure cover in such a way that additional work is necessary to rectify the envelope of the toothed and hardened cylinder and obtain a regular conditioning effect on the whole. the length of the cylinder. As the hardened casing is partly removed by an additional grinding operation, the cylinders thus treated are subject to significant wear. The present invention therefore aims to provide a chopper of the type indicated in the preamble in which the cylinders do not need to be replaced as a whole in the event of wear. According to the invention, this object is achieved by the fact that the cylinder casing and the two closure lids are tightened against each other in a removable manner and centered by a pull rod which passes centrally through the lids and the support pins associated.

L'invention va maintenant etre expliquée plus en détail å l'aide d'un mode de réalisation et de plusieurs figures représentant celui-ci de façon schématique2 dans lesquelles:
la figure 1 est une vue latérale d'une ramasseuse-hacheuse,
la figure 2 est une représentation à plus grande échelle de la partie de conditionnement de la ramasseuse-hacheuse représentée à la figure 1,
la figure 3 est une vue en coupe d'un rouleau écraseur de la partie de conditionnement, à l'état monté, et
la figure 4 est une autre vue du cylindre de conditionnement montré à l'état éclaté.
The invention will now be explained in more detail using an embodiment and several figures representing it schematically2 in which:
FIG. 1 is a side view of a harvester-chopper,
FIG. 2 is a representation on a larger scale of the packaging part of the chopper represented in FIG. 1,
FIG. 3 is a sectional view of a crushing roller of the packaging part, in the assembled state, and
Figure 4 is another view of the conditioning cylinder shown in the exploded state.

En 1 est désignée une ramasseuse-hacheuse automotrice dont les organes d'introduction avant 2 dirigent le produit moissonné vers un tambour de hachage 3 qui coopère avec un contre-couteau fixe. De là, le produit haché parvient dans une cheminée d'éjection 4 dans laquelle il est réduit en menus fragments par des cylindres de conditionnement 5 et 6 puis ensuite éjecté. Un tube coudé d'éjection 9 s'y raccorde avec interposition d'un dispositif d'éjection additionnel 7 et d'une couronne tournante 8, tube par lequel le produit haché est envoyé par exemple dans un véhicule d'accompagnement. Les cylindres de conditionnement 5 et 6 selon ce mode de réalisation comprennent une enveloppe cylindrique à denture externe 10, l'enveloppe 10 présentant sur ses côtés frontaux des collerettes annulaires internes 11 et 12. In 1 is designated a self-propelled chopper whose front introduction members 2 direct the harvested product to a chopping drum 3 which cooperates with a fixed counter knife. From there, the chopped product arrives in an ejection stack 4 in which it is reduced into small fragments by conditioning cylinders 5 and 6 and then ejected. A bent ejection tube 9 is connected thereto with the interposition of an additional ejection device 7 and a rotating crown 8, a tube by which the chopped product is sent, for example, to an accompanying vehicle. The conditioning cylinders 5 and 6 according to this embodiment comprise a cylindrical envelope with external toothing 10, the envelope 10 having on its front sides internal annular flanges 11 and 12.

Dans ces collerettes 11 et 12 peuvent etre insérées les couvercles de fermeture 13 et 14 qui sont munis de tourillons de support 15 et 16.In these flanges 11 and 12 can be inserted the closure covers 13 and 14 which are provided with support pins 15 and 16.

L'un des deux tourillons de support, à savoir le tourillon 15, comprend un siège 17 contre lequel est pressé le palier 18 que le siège 17 dépasse légèrement vers l'extérieur. L'autre tourillon de support 16 comprend également un siège 19 avec un palier 20 pressé sur lui, contre lequel repose un anneau d'écartement 21 qui dépasse le siège 19 vers l'extérieur. Contre l'anneau d'écartement 21 s'appuie une poulie d'entratnement 22 qui est calée sur un prolongement 23 du tourillon 16 et fait saillie de ce dernier vers l'extérieur. Comme on peut le voir clairement à la figure 3, tous ces composants sont centrés par une unique tige de traction 30 qui est centrée dans des alésages centraux 24, 25 des couvercles de fermeture 13 et 14 et les maintient sous forme d'un ensemble unitaire.Les consoles 26 et 27 qui entourent les paliers 18 et -20 peuvent alors être vissées au moyen de vis 28 sur le châssis porteur 29 de la cheminée d'éjection 4. Lorsqu'une enveloppe de cylindre 5, 6 est usée, il n'est plus nécessaire selon la présente invention, et comme cela était indispensable jusqu'ici, de remplacer l'ensemble des cylindres. On remplace simplement la partie usée, c' est-a-dire l'enveloppe 10. Les couvercles de fermeture et les tourillons de support qui lui sont reliés ainsi que les paliers associés restent disponibles pour une nouvelle utilisation. Des économies considérables en sont la conséquence.One of the two support trunnions, namely the trunnion 15, comprises a seat 17 against which the bearing 18 is pressed against which the seat 17 projects slightly outward. The other support pin 16 also includes a seat 19 with a bearing 20 pressed against it, against which rests a spacer ring 21 which projects beyond the seat 19 outwards. Against the spacer ring 21 is supported a drive pulley 22 which is wedged on an extension 23 of the pin 16 and projects from the latter outward. As can be clearly seen in Figure 3, all of these components are centered by a single pull rod 30 which is centered in central bores 24, 25 of the closure covers 13 and 14 and holds them as a unitary assembly .The brackets 26 and 27 which surround the bearings 18 and -20 can then be screwed by means of screws 28 to the supporting frame 29 of the exhaust chimney 4. When a cylinder casing 5, 6 is worn, there is no 'is no longer necessary according to the present invention, and as was essential hitherto, to replace all the cylinders. The worn part is simply replaced, that is to say the casing 10. The closure covers and the support pins which are connected to it as well as the associated bearings remain available for new use. Significant savings are the result.

Comie il va de soi, et comme il résulte déjà de ce qui précède, l'invention ne se lignite nullement A ceux de ses modes de réalisation, non plus qu'a ceux des modes de réalisation de ses diverses parties, ayant été plus spécialement envisagées; elle en embrasse, au contraire, toutes les variantes.  As it goes without saying, and as already follows from the foregoing, the invention is in no way lignite to those of its embodiments, no more than to those of the embodiments of its various parts, having been more specially considered; on the contrary, it embraces all its variants.
