Abstract
Description
Tamiseuse Sieve shaker
La présente invention se rapporte aux machines agricoles, appelées communément tamiseuses ou épierreuses-émotteuses, pour la séparation d'éléments qui se trouvent dans des billons tels que pierres, mottes ou racines.The present invention relates to agricultural machines, commonly called sifters or cleansers, for the separation of elements which are found in logs such as stones, lumps or roots.
Plus précisément, elle se rapporte aux tamiseuses qui comprennent des moyens de coupe, des moyens de séparation et un dispositif d'acheminement, vers les sillons et/ou dans un récipient, des éléments qui ne traversent pas lesdits moyens de séparation.More specifically, it relates to sieving machines which comprise cutting means, separation means and a device for conveying, towards the grooves and / or in a container, elements which do not pass through said separation means.
Un billon, tel que définit dans le présent texte, doit être compris comme une zone de terre élevée formée entre deux sillons. Sa largeur est sensiblement équivalente à la distance entre les roues 'd'une machine agricole utilisée pour sa formation ou son traitement.A log, as defined in this text, must be understood as an area of elevated soil formed between two furrows. Its width is substantially equivalent to the distance between the wheels ' of an agricultural machine used for its formation or its treatment.
Les documents US-A-4 548 275 et GB-A-2 238 219 décrivent des épierreuses- émotteuses qui sont munies d'une lame pour trancher horizontalement la terre à une certaine profondeur, de plusieurs tapis transporteurs-séparateurs et d'un dispositif d'acheminement des pierres et mottes de grande taille.Documents US-A-4 548 275 and GB-A-2 238 219 describe cleansers that are provided with a blade for slicing the earth horizontally to a certain depth, several conveyor-separator belts and a device for transporting large stones and clods.
Le recours à une pluralité de tapis transporteurs-séparateurs, trois par exemple, permet de réduire l'effort subi par ceux-ci et ainsi de prolonger leur durée de vie. Un tapis transporteur-séparateur, tel que celui décrit dans le document US-A-5 671 839, se compose le plus souvent d'une série de tiges disposées parallèlement et perpendiculairement par rapport au sens de la marche du tracteur, les tiges sont retenues à leurs extrémités par des courroies.The use of a plurality of conveyor-separator belts, three for example, makes it possible to reduce the effort undergone by them and thus to prolong their service life. A conveyor-separator belt, such as that described in document US-A-5 671 839, most often consists of a series of rods arranged parallel and perpendicular to the direction of travel of the tractor, the rods being retained at their ends by belts.
La distance entre deux tiges adjacentes définit la taille maximum d'un élément (terre, pierre, motte, etc..) qui peut traverser le tapis et retourner dans le billon sous-jacent.The distance between two adjacent rods defines the maximum size of an element (earth, stone, clod, etc.) which can pass through the carpet and return to the underlying log.
Les éléments de plus grande taille sont acheminés pour être déposés dans les sillons avoisinants ou dans un récipient qui sera vidé en dehors du champ. Les épierreuses-émotteuses de l'état de la technique présentent l'inconvénient de ne pouvoir traiter qu'un billon à la fois, ce qui résulte en une durée de travail relativement longue et augmente les coûts de production.Larger items are transported to be placed in the neighboring furrows or in a container which will be emptied out of the field. Prior art cleansers have the disadvantage of being able to process only one log at a time, which results in a relatively long working time and increases production costs.
La présente invention a le mérite de réduire de manière notable la durée de travail.The present invention has the merit of significantly reducing the working time.
La machine selon l'invention comprend des moyens de coupe, des moyens de séparation et un dispositif d'acheminement, vers les sillons et/ou dans un récipient, des éléments qui ne traversent pas lesdits moyens de séparation. Elle se caractérise par le fait que les dimensions des moyens de coupe et des moyens de séparation sont adaptées pour traiter une zone équivalente ou supérieure à un billon et demi.The machine according to the invention comprises cutting means, separation means and a device for conveying, towards the grooves and / or in a container, elements which do not pass through said separation means. It is characterized by the fact that the dimensions of the cutting means and of the separation means are suitable for treating an area equivalent to or greater than a log and a half.
Selon un mode de réalisation de l'invention, les dimensions des moyens de coupe et des moyens de séparation sont adaptées pour traiter une zone sensiblement supérieure à deux billons.According to one embodiment of the invention, the dimensions of the cutting means and of the separation means are suitable for treating an area substantially greater than two ridges.
Selon un autre mode de réalisation, les moyens de séparation comprennent au moins trois tapis séparateurs placés en parallèle, la largeur du tapis central étant sensiblement égale à la largeur d'un billon et représente approximativement le double de la largeur de chaque tapis adjacent.According to another embodiment, the separation means comprise at least three separating belts placed in parallel, the width of the central carpet being substantially equal to the width of a log and represents approximately twice the width of each adjacent carpet.
Alternativement, les tapis séparateurs peuvent être remplacés par des rouleaux séparateurs ou tout autres moyens de séparation de l'état de la technique.Alternatively, the separating belts can be replaced by separating rollers or any other prior art separation means.
Ainsi, avec une machine adaptée pour le traitement simultané de deux billons, le nombre de passages du tracteur est-il réduit de moitié.Thus, with a machine adapted for the simultaneous treatment of two logs, the number of tractor passages is reduced by half.
La durée de travail peut encore être diminuée de manière notable, d'un facteur deux environ, en munissant la machine selon l'invention de moyens pour la formation d'au moins un billon, tels que socs et coutres, qui se situent à l'avant de la machine.The working time can be further reduced significantly, by a factor of about two, by providing the machine according to the invention with means for forming at least one log, such as coulters and coulters, which are located at the front of the machine.
Selon un autre mode de réalisation, la machine selon l'invention est munie de moyens de déflection destinés à acheminer vers les billons, les éléments qui traversent les moyens de séparation. Les sillons étant destinés uniquement à recevoir les éléments qui n'ont pas traversés les moyens de séparation. Des modes particuliers de l'invention sont décrits ci-après en se basant sur les figures suivantes:According to another embodiment, the machine according to the invention is provided with deflection means intended to convey to the logs, the elements which pass through the separation means. The grooves being intended only to receive the elements which have not passed through the separation means. Specific modes of the invention are described below based on the following figures:

La figure 1 illustre la machine selon l'invention vue de côté La figure 2 montre la machine de la figure 1 vue de dessus La figure 3 montre la machine de la figure 1 vue de l'arrièreFigure 1 illustrates the machine according to the invention seen from the side Figure 2 shows the machine of Figure 1 seen from above Figure 3 shows the machine of Figure 1 seen from the back
0 Les figures 1 et 2 présentent une tamiseuse tractée munie de moyens de fixation et d'entraînement (1) des différentes parties motorisées de la tamiseuse . Deux traceurs de sillons (2,2'), comprenant chacun un soc (3) et un coutre (4), sont situés à l'avant de la tamiseuse et dans le prolongement de lames tranchantes (5,6,6'). Un cylindre rotatif (7), muni de dents- (non-visibles sur les figures), est placé sensiblement au- 5 dessus des lames tranchantes (5,6,6') afin de faciliter l'acheminement de la terre vers des tapis séparateurs-transporteurs (8,9,10,1 1 ,11',12,,12,,13,13,). Le recours à une pluralité de tapis présente entre autre l'avantage de réduire l'effort qu'ils subisse et par la même de prolonger leur durée de vie. Chaque tapis est constitué d'une pluralités de tiges, placées parallèlement les unes 0 par rapport aux autres et perpendiculairement au sens de la marche de la tamiseuse, la distance entre deux tiges définissant la taille maximale des éléments qui peuvent traverser le tapis et retourner dans un billon.0 Figures 1 and 2 show a towed sieve shaker provided with fixing and driving means (1) of the different motorized parts of the sieve shaker. Two groove markers (2,2 '), each comprising a ploughshare (3) and a coulter (4), are located at the front of the sieve shaker and in line with sharp blades (5,6,6'). A rotary cylinder (7), provided with teeth (not visible in the figures), is placed substantially above the cutting blades (5,6,6 ') in order to facilitate the conveying of the earth to carpets separators-carriers (8,9,10,1 1, 11 ', 12,, 12,, 13,13,). The use of a plurality of carpets has the advantage, among other things, of reducing the effort they undergo and at the same time of extending their service life. Each conveyor consists of a plurality of rods, placed parallel to each other and perpendicular to the direction of operation of the sieve shaker, the distance between two rods defining the maximum size of the elements which can pass through the conveyor and return to a ridge.
Les éléments qui ne traversent pas les tapis, essentiellement des pierres et mottes de grande taille, sont transportés par les tapis dans des conduits d'acheminement 5 (14,14'), illustrés également sur la figure 3, qui débouchent en dessus des sillons et en avant des roues arrières (15,15') de la tamiseuse, de sorte que le passage de ces roues assure un meilleur enfouissement des éléments dans les sillons.The elements which do not pass through the carpets, essentially large stones and clods, are transported by the carpets in conveying conduits 5 (14,14 '), also illustrated in FIG. 3, which open above the furrows and in front of the rear wheels (15,15 ') of the sieve shaker, so that the passage of these wheels ensures better burial of the elements in the furrows.
Une série de déflecteurs, constitués de plaque en tôle (16,16',17,17'), sont placés 0 sous les tapis de façon à diriger les éléments qui traversent les tapis (8,9,10,11 , 11 ',12„12',13,13') vers les billons.A series of deflectors, made of sheet metal plate (16,16 ', 17,17'), are placed 0 under the carpets so as to direct the elements which pass through the carpets (8,9,10,11, 11 ', 12 „12 ', 13,13') towards the ridges.
Il va sans dire que l'invention n'est pas limitée au mode de réalisation décrit ci- dessus. Les 3 séries de tapis parallèles peuvent être remplacées par une série de tapis dont la largeur serait sensiblement équivalente à celle de deux billons et deux sillons. Le recours à un seul tapis serait également envisageable.It goes without saying that the invention is not limited to the embodiment described above. The 3 series of parallel belts can be replaced by a series of belts whose width would be substantially equivalent to that of two ridges and two grooves. The use of a single carpet would also be possible.
De même, il serait parfaitement envisageable de remplacer les tapis par des rouleaux séparateurs tout en retirant les avantages de la présente invention.Likewise, it would be perfectly conceivable to replace the belts with separating rollers while retaining the advantages of the present invention.
A relever enfin que la tamiseuse pourrait être conçue avec des dimensions plus réduites qui permettraient de traiter non pas deux billons simultanément mais un billon et demi.Lastly, it should be noted that the sieve could be designed with smaller dimensions which would make it possible to process not two logs simultaneously but one and a half logs.
Il convient de relever également que le traitement d'une zone inférieure à un billon et demi ne présenterait que peu d'intérêt dans la mesure où le nombre de passages du tracteur, par rapport aux dispositifs de l'état de la technique, ne serait pas réduit. It should also be noted that the treatment of an area less than a log and a half would be of little interest insofar as the number of passages of the tractor, compared with the devices of the state of the art, would not be not reduced.
