Abstract
Description
La présente invention concerne un perfectionnement aux enfouisseurs de lisier ou d'autres liquides, tels que des liquides azotés, des boues liquides, etc. The present invention relates to an improvement to the landfill of slurry or other liquids, such as nitrogenous liquids, liquid sludges, etc.
Plus spécialement, l'invention concerne un enfouisseur de lisier comportant, à l'avant, deux disques avant qui creusent ensemble un sillon, dont les bords sont refermés, à l'arrière, par des moyens adéquats, tels que d'autres disques. Les disques avant ont leurs orientations symétriques par rapport à la direction de déplacement et à la verticale, en formant, vu de dessus, les deux côtés d'un coin, les deux disques étant tangents à l'avant au sommet du coin. Des enfouisseurs de ce type sont déjà connus. More specifically, the invention relates to a slurry burier comprising, at the front, two front discs which together dig a furrow, the edges of which are closed, at the rear, by suitable means, such as other discs. The front discs have their orientations symmetrical with respect to the direction of movement and vertically, forming, seen from above, the two sides of a corner, the two discs being tangent to the front at the top of the corner. Burialers of this type are already known.
Au cours de l'utilisation de l'enfouisseur, les pourtours des disques s'usent si bien qu'au bout d'un certain temps, ils ne sont plus rigoureusement tangents à l'avant. I1 en résulte que le sillon qu'ils tracent est moins profond et même que les disques laissent entre eux une étroite bande de sol non travaillée, ce qui constitue un obstacle à l'écoulement en profondeur du lisier. L'enfouisseur n'a plus une efficacité maximale. During use of the burier, the edges of the discs wear out so that after a certain time, they are no longer rigorously tangent at the front. As a result, the furrow which they trace is less deep and even that the discs leave between them a narrow strip of unworked soil, which constitutes an obstacle to the deep flow of slurry. The burier no longer has maximum efficiency.
Un objet de l'invention consiste à prévoir des moyens qui sont destinés à pouvoir rapprocher les disques qui se sont usés au cours du travail. An object of the invention is to provide means which are intended to be able to bring the discs which have worn down during work.
Suivant une caractéristique de l'invention, il est prévu un enfouisseur du type mentionné ci-dessus, qui comporte des disques montés en coin pour créer un sillon, les disques étant montés sur leurs paliers avec chacun au moins une cale sous forme d'une rondelle que l'on peut enlever, à la demande, pour rapprocher les deux disques. According to a characteristic of the invention, there is provided a burier of the type mentioned above, which comprises discs mounted in a corner to create a groove, the discs being mounted on their bearings with each at least one shim in the form of a washer that can be removed, on request, to bring the two discs closer.
Suivant une autre caractéristique, chacun de ces disques comprend une couronne plane entourant une calotte sensiblement sphérique, la flèche de la calotte ayant une grandeur variable selon la nature du sol à travailler. According to another characteristic, each of these discs comprises a flat crown surrounding a substantially spherical cap, the deflection of the cap having a variable size depending on the nature of the soil to be worked.
Suivant une autre caractéristique, la largeur de la couronne plane est variable. According to another characteristic, the width of the flat crown is variable.
Suivant une autre caractéristique, chaque disque avant comporte un enjoliveur central hermétique qui comprend une plaque interne qui s'adapte au disque et qui porte des goujons servant à monter le disque sur son moyeu, l'enjoliveur enveloppant la plaque et les goujons. According to another characteristic, each front disc has a hermetic central cover which includes an internal plate which adapts to the disc and which carries studs used to mount the disc on its hub, the cover wrapping the plate and the studs.
Les caractéristiques de l'invention mentionnées ci-dessus, ainsi que d' autres, apparaîtront plus clairement à la lecture de la description suivante, ladite description étant faite en relation avec les dessins joints, parmi lesquels:
la Fig. 1 est une vue partielle en perspective d'un enfouisseur de lisier comportant le perfectionnement de l'invention, et la la Fig. 2 est une vue partielle en coupe qui montre comment les cales d'usure sont montées.The characteristics of the invention mentioned above, as well as others, will appear more clearly on reading the following description, said description being made in relation to the accompanying drawings, among which:
Fig. 1 is a partial perspective view of a slurry burier comprising the improvement of the invention, and FIG. 2 is a partial sectional view which shows how the wear blocks are mounted.
L'enfouisseur de la Fig. 1 comprend, à l'avant, deux disques 1 et 2 dont les moyeux 3 et 4 sont montés à l'extrémité basse d'un montant 5. Au montant 5, est également fixé un tuyau 6 d'écoulement du lisier et sont articulés deux bras 7 et 8 qui sont sensiblement horizontaux et dont les extrémités libres 9 et 10 supportent respectivement des montants coudés 11 et 12 auxquels sont reliés les moyeux de deux disques arrière 13 et 14. Des ressorts de compensation 15 et 16 relient les bras 7 et 8 au bas du montant 3 et appliquent fortement les disques 13 et 14 contre le sol. Les disques 13 et 14 présentent, dans l'exemple montré, des encoches. The burier of FIG. 1 comprises, at the front, two discs 1 and 2, the hubs 3 and 4 of which are mounted at the lower end of an upright 5. At the upright 5, is also attached a manure flow pipe 6 and are articulated two arms 7 and 8 which are substantially horizontal and whose free ends 9 and 10 respectively support bent uprights 11 and 12 to which the hubs of two rear discs 13 and 14 are connected. Compensating springs 15 and 16 connect the arms 7 and 8 at the bottom of the upright 3 and strongly apply the discs 13 and 14 against the ground. The discs 13 and 14 have, in the example shown, notches.
Vu de dessus, les disques I et 2, qui en première approximation sont plans, forment les côtés d'un coin dont le sommet est vers l'avant. L'écartement entre les disques est, au repos, de l'ordre de 3 mm. Les éléments 1, 7, 11 et 13 sont respectivement symétriques des éléments 2, 8, 12 et 14 par rapport à un plan vertical orienté dans le sens de déplacement de l'enfouisseur. Seen from above, the discs I and 2, which as a first approximation are planar, form the sides of a corner whose apex is forward. The spacing between the discs is, at rest, of the order of 3 mm. The elements 1, 7, 11 and 13 are respectively symmetrical with the elements 2, 8, 12 and 14 with respect to a vertical plane oriented in the direction of movement of the burier.
Par ailleurs, les disques 1 et 2 ont été ci-dessus supposés plans, mais ils comportent, de préférence, chacun une couronne 18 entourant une calotte sensiblement sphérique 19. La largeur de la couronne 18 est choisie plus ou moins grande selon la nature du sol à travailler. De même, la flèche de la calotte 19 est choisie plus ou moins grande. Furthermore, the disks 1 and 2 have been assumed above to be planes, but they preferably each have a crown 18 surrounding a substantially spherical cap 19. The width of the crown 18 is chosen to be greater or less depending on the nature of the soil to work. Likewise, the arrow of the cap 19 is chosen to be greater or less.
Comme le montre la Fig. 2, entre le sommet de la calotte 19 et le moyeu 3, est interposée une cale 17 qui est constituée par une rondelle. Bien entendu, au lieu d'une seule cale, on peut en prévoir plusieurs. Au bout d'un certain temps d'utilisation de l'enfouisseur, les disques 1 et 2 ont leur périphérie qui s'use si bien qu'ils ne sont plus tangents. Il suffit alors de démonter les disques et d'enlever les cales 17 pour obtenir à nouveau l'état de tangence. As shown in Fig. 2, between the top of the cap 19 and the hub 3, there is interposed a wedge 17 which is constituted by a washer. Of course, instead of a single wedge, several can be provided. After a certain time of use of the burier, the discs 1 and 2 have their periphery which wears out so that they are no longer tangent. It then suffices to disassemble the discs and remove the shims 17 to again obtain the state of tangency.
A la Fig. 2, on a montré deux enjoliveurs 20 qui comporte une plaque de contact avec les disques 1 et 2, la plaque étant munie de goujons 21. Les goujons 21 servent à relier les disques 1 et 2 aux moyeux 3 et 4. Comme chaque enjoliveur 20 enveloppe les goujons 21, il protège ceux-ci des entrées de terre et donc aussi les moyeux. Par filleuls, chaque enjoliveur 20 a une forme cylindrique, une résistance suffisante et une hauteur suffisante, par rapport à la surface externe du disque 1 ou 2, pour empêcher les disques de s'enfoncer dans un sol meuble au-delà de leur axe. In Fig. 2, two hubcaps 20 have been shown which comprises a contact plate with the discs 1 and 2, the plate being provided with studs 21. The studs 21 are used to connect the discs 1 and 2 to the hubs 3 and 4. Like each hubcap 20 envelops the studs 21, it protects them from earth inlets and therefore also the hubs. By godchildren, each hubcap 20 has a cylindrical shape, sufficient strength and sufficient height, relative to the external surface of the disc 1 or 2, to prevent the discs from sinking into loose soil beyond their axis.
