Abstract

Semimounted grader comprising a chassis under which the blade is fixed, a beam which comprises a point of articulation with the chassis, which enables the height of the blade to be adjusted. The chassis is fixed in a pivoting manner on the rear axle which enables the assembly of the chassis 1 of the beam 2 and of the blade 4 to pivot about a horizontal axis parallel to the direction of travel. The blade pivots about a vertical axis. The blade is located just in front of the rear wheels, which minimises the vertical movements of the blade resulting from the state of the ground on which the towing vehicle, attached further forward, travels. The lower end of the blade 6 is an interchangeable wearing plate.

Description

La prdsente invention concerne une lame Niveleuse profileuse fixée sous un chassis semiporté . Ce chassis comporte à l'arrière de la lame 2 roues porteuses et à l'avant une flèche articulée qui peut âtre accrochée à l'arrière d'un véhicule tracteur. The present invention relates to a profiling grader blade fixed under a semiport chassis. This chassis comprises at the rear of the blade 2 carrying wheels and at the front an articulated boom which can be hung on the rear of a towing vehicle.

La Niveleuse profileuse pourra âtre utilisée pour répartir les terres horizontalement en surface, pour profiler une pente sur les chemins ou des ados sur les champs pour llXcoulement des eaux. The profiling grader can be used to distribute the land horizontally on the surface, to profile a slope on the paths or for teenagers on the fields for water flow.

L'invention pourra être bien comprise à l'aide de la description qui suit ainsi que des dessins ci-annexs. The invention will be clearly understood with the aid of the description which follows as well as of the appended drawings.

La figure 1 présente la Niveleuse en élévation. Sur cette figure l'on remarque la position de l'axe 3 reliant la flèche 2 au chassis 1. La lame est fixée sous le chassis 1 . L'allongement du vérin 14 conduit compte tenu de la position fixe en hauteur de la pièce d'attelage 15 de la flèche 2, à relever l'axe d'articulation 3 donc à relever la lame 4. Figure 1 shows the Grader in elevation. In this figure, we can see the position of the axis 3 connecting the arrow 2 to the chassis 1. The blade is fixed under the chassis 1. The extension of the jack 14 leads, taking into account the fixed height position of the coupling piece 15 of the boom 2, to raise the hinge pin 3 and therefore to raise the blade 4.

La figure 2 montre également l'axe vertical 5 autour duquel la lame pivote. Figure 2 also shows the vertical axis 5 around which the blade pivots.

La figure 3 montre l'essieu 10 reliant les deux roues 11 et 12. Figure 3 shows the axle 10 connecting the two wheels 11 and 12.

Cet essieu 10 est relié au chassis 1 par une pièce ayant un axe horizontal 9. Le chassis 1 et l'essieu 10 pivotent donc l'un par rapport à l'autre autour de l'axe horizontal 9. Un bloc de les targe 13 assure une augmentation de la charge sur les roues il et 12.This axle 10 is connected to the chassis 1 by a part having a horizontal axis 9. The chassis 1 and the axle 10 therefore pivot relative to each other about the horizontal axis 9. A block of the pins 13 ensures an increase in the load on wheels il and 12.

Cette Niveleuse profileuse se caractérise par le fait qu'en position de travail.normal la flèche 2 est approximativement horizontale. Cette disposition associée au fait que si le sol est dur ou résistant l'ensemble du chassis a tendance à pivoter autour de
l'extrémité coupante 6 de la lame 4. Il s'en suit donc selon la volonté du conducteur de l'ensemble un transfert des masses pesantes de l'ensemble des roues 11 et 12 vers la lame 4 et plus particulièrement vers l'arête 6. L'effort de pression vers le bas qui permet à la lame 4 de stenfoncer dans le sol est donc augmenté.This profiling grader is characterized by the fact that in the normal working position, the arrow 2 is approximately horizontal. This provision associated with the fact that if the ground is hard or resistant the whole chassis tends to pivot around
the cutting end 6 of the blade 4. It therefore follows, according to the wishes of the driver of the assembly, a transfer of the heavy masses from all of the wheels 11 and 12 to the blade 4 and more particularly to the edge 6. The downward pressure force which allows the blade 4 to sink into the ground is therefore increased.

La conception de cette Niveleuse quoique simple assure à la lame tous les mouvements nécessaires à un travail correct. The design of this Grader, although simple, ensures that the blade has all the movements necessary for correct work.

La figure 1 montre qu'à l'aide de l'articulation horizontale 3 et du vérin 14 l'allongement du vérin 14 assure un réglage en hauteur de la lame. Figure 1 shows that using the horizontal joint 3 and the cylinder 14 the extension of the cylinder 14 provides a height adjustment of the blade.

La figure 2 montre l'axe vertical 5 autour duquel pivote la lame 4 par rapport au chassis 1. FIG. 2 shows the vertical axis 5 around which the blade 4 pivots relative to the chassis 1.

La figure 3 montre l'axe horizontal 9 autour duquel pivote 1'ensemble du chassis et de la lame par rapport l'essieu TD
L'essieu 10 étant maintenu à une distance fixe du sol part inter- médiaire des roues 11 et 12. Ce dispositif permet à la lame de réaliser un profilage horizontal ou obliqua du sol. Figure 3 shows the horizontal axis 9 around which pivots all of the chassis and the blade relative to the TD axle
The axle 10 being maintained at a fixed distance from the ground intermediate part of the wheels 11 and 12. This device allows the blade to produce a horizontal or oblique profiling of the ground.

Claims

1)> Characterized semi-mounted profiling grader; in that the position of the hinge pin 3 of the boom 2 ensures with the help of a hydraulic or mechanical jack system or any other system a height adjustment of the leveler blade.

The position of the axis 3 being clearly above the line through which the traction axis passes the coupling ring and point of the blade, it occurs when the resistance is high and as the traction force increases a load transfer from the wheels to the blade, which ensures correct grounding of the blade.

2) Semi-mounted profiling grader according to claim 1 characterized in that the position of the hinge pin 9 of the chassis ensures with the help of a hydraulic or mechanical jack system or any other system an inclination adjustment of the blade and this around a horizontal axis parallel to the direction of travel of the blade.

3) Semi-mounted profiling grader according to claim 1 or 2 characterized in that the blade can pivot around a vertical axis 5 allowing in the right position to transport the material on the ground and tilting to the right or to the left can drive the material from the ground on one side or the other.

4) Semi-mounted profiling grader according to one of claims 1 to 3 characterized in that the notched profile of the tires ensures correct grip on the ground and prevents slipping.

5) Semi-mounted profiling grader according to one of claims 1 to 4 characterized in that a rotating ring fixed at the end of the boom, ensuring the liailssn; f! Vec tractor, avoiding the jamming of the coupling pin during movements of the chassis and the blade around the hinge pin 9.

6) Semi-mounted profiling grader according to one of claims 1 to 5 characterized in that the interchangeable wear plate forming the cutting edge 6 of the blade 4 can be replaced or can be increased by a band with teeth or flexible band for snow removal.

7) semi-mounted profiling grader according to one of claims 1 to 6 characterized in that the blade being located just in front of the two wheels 11 and 12, the state of the ground on which the tractor vehicle rolls has little influence on the condition of the final soil because the machine's towing hook is far in front of the blade.
