Abstract

The tip (12) is fixed by bolts (19,20,21) onto the blade (18) and counter blade (13). The tip is manufactured from a constant rectangular or square section and has at its end a tungsten carbide edge.

Description

La présente invention concerne le montage et la concepton de pointes en acier
traité muniesd'une pastille de carbure de tungstène, sur des lames de décompac
teurs de forme courbe (fig 7 ), destinées à travailler en profondeur les terres
agricoles.The present invention relates to the mounting and design of steel spikes
treated with a tungsten carbide pellet, on decompacor blades
curved formers (fig 7), intended to work in depth the soil
agricultural.

Ces lames sont vendues depuis quelques années en Europe, et connues dans
les milieux professionnels de l'agriculture sous le nom de lame "Michel" nom de
l'inventeur et développées par différentes sociétés européennes.These blades have been sold for a few years in Europe, and known in
professional circles of agriculture under the name of blade "Michel" name of
the inventor and developed by different European companies.

Ces lames sont montées tous les 35/40 cm sur un chassis, I'ensemble étant
tiré par un tracteur travaillant des largeurs pouvant atteindre 6 à 8 m.These blades are mounted every 35/40 cm on a frame, the whole being
pulled by a tractor working widths up to 6 to 8 m.

Sur les figures (2), (4) et ( 6 ), le vecteur S représente le sens de pénétra
tion des lames dans le sol.In figures (2), (4) and (6), the vector S represents the direction of penetration.
tion of the blades in the ground.

La zone d'usure dûe au frottement de la terre sur les pointes et contre lames
est localisée en U.The wear area due to the friction of the earth on the tips and against blades
is located in U.

Les montages de ces pointes sont actuellement conçues de deux façons.
a ) Les figures ( 1 ) et (2) montrent ce premier montage, la pointe (1)
en acier traité est soudée sur une con tre-la me (2), I'ensemble
ainsi réalisé est fixé sur la lame (3) par l'intermédiaire des vis (4)eut(5). The assemblies of these points are currently designed in two ways.
a) Figures (1) and (2) show this first assembly, the tip (1)
in treated steel is welded to a counter beam (2), the whole
thus produced is fixed to the blade (3) by means of the screws (4) eut (5).

La pointe ( 1 ) s'use en général plus vite que la contrFlame (2),
d'où l'obligation de la déssouder de la contre lame pour en ressou
der une neuve, entraînant un coût supplémentaire pour l'utilisateur.
b) Les figures (3) et (4) montrent le deuxième montage actuellement
utilisé, la pointe (6) en acier traité se fixe sur la lame ( 7 ), la contre
lame( 8) étant prise en sandwich grâce a. la mortaise (9) réalisée
dans la pointe (6), ainsi l'ensemble pointe/contre-lame/ lame est
solidaire et fixé de façon semi-rigide par l'intermédiaire de goupilles
élastiques 10) et (11).The tip (1) generally wears out faster than the counterblade (2),
hence the obligation to unsolder the counter blade to re-weld
der a new one, resulting in an additional cost for the user.
b) Figures (3) and (4) show the second assembly currently
used, the point (6) in treated steel is fixed on the blade (7), the counter
blade (8) being sandwiched thanks to a. the mortise (9) made
in the point (6), so the point / counter blade / blade assembly is
integral and rigidly fixed by means of pins
elastic bands 10) and (11).

Dans ce cas de figure, la pointe (6) est entièrement oxycoupée
pour éffectuer la mortaise ( 9 ), cette solution est couteuse et délicate
à réaliser.In this case, the point (6) is entirely flame cut
to make the mortise (9), this solution is expensive and delicate
to achieve.

En résumé, ces deux exemples démontrent que les pointes actuelles sont d'un prix de revient élévé et s'usent trop rapidement
La présente invention a pour but de supprimer ces inconvénients en concevant une pointe différente, par:
Le choix de la matière (carbures).In summary, these two examples demonstrate that the current spikes are expensive and wear out too quickly.
The aim of the present invention is to eliminate these drawbacks by designing a different tip, by:
The choice of material (carbides).

Le processus de fabrication ( laminés standards et matriçage ). The manufacturing process (standard laminates and stamping).

Son mode de fixation sur la contre-lame et la lame (boulons).  Its method of attachment to the counter blade and the blade (bolts).

La description qui suit va le démontrer. The following description will demonstrate this.

Les figures (5) et ( 6) représentent le nouveau montage objet de l'invention. Figures (5) and (6) show the new assembly object of the invention.

La pointe (12) en acier traité, réalisée à partir d'une barre de profil constant, rectangulaire ou cané est pliée pour épouser exactement la forme de la contre-lame (13) et dépasser celle-ci d'environ 50 a 100 m/m. The point (12) in treated steel, made from a bar of constant profile, rectangular or caned is bent to exactly match the shape of the counter blade (13) and exceed it by about 50 to 100 m / m.

A son extremité, sur la partie frontale est brasée une pastille de carbure de tungstène (15), I'usure de la pointe s'en trouve considérablement améliorée, la dureté pouvant atteindre les 2000 Vickers. At its end, on the front part is brazed a tungsten carbide pellet (15), the wear of the point is considerably improved, the hardness being able to reach 2000 Vickers.

La forme de la contre-lame (13) est modifiée en zone ( 16 ) pour percer un trou (17) de manière à fixer la pointe (12) de façon plus rigide sur la lame (18).  The shape of the counter blade (13) is modified in the area (16) to drill a hole (17) so as to fix the point (12) more rigidly on the blade (18).

Les boulons (19), (20) et (21) assemblent, pointe, contre-lame et lame. The bolts (19), (20) and (21) assemble, point, counter blade and blade.

Lorsque les conditions du sol le permettent ( terres légères J, la pointe (12) peut être fabriquée sans la pastille de carbure de tungstène (15), représantant ainsi une variante de l'invention. When the ground conditions allow it (light earth J, the point (12) can be manufactured without the tungsten carbide pellet (15), thus representing a variant of the invention.

La réalisation de la pointe est envisagée au niveau industriel pour amver au premier objectif visé par cette invention : la réduction du prix de revient
Le processus choisi est le matriçage, pour obtenir en une seule frappe, les trous et la forme de la pointe.The production of the tip is envisaged at the industrial level to meet the first objective targeted by this invention: the reduction of the cost price
The chosen process is forging, to obtain in a single strike, the holes and the shape of the point.

Ainsi la pointe sera fabriquée en un minimum d'opérations, représentant un réel progrès par rapport à ce qui est proposé actuellement.  Thus the tip will be manufactured in a minimum of operations, representing real progress compared to what is currently offered.
