Description

       

   <EMI ID=1.1> 

  
des tranchées dans le sol.

  
On sait que, notamment en vup de la pose de cables ou canalisations souterrains, il est nécessaire d'ouvrir des tranchées dans le sol. A cet

  
effet, on connaît déjà des machines, dites trancheuses, comportant un chassis automobile, par exemple un tracteur, sur lequel est montée une roue susceptible d'être entraînée en rotation et munie à sa périphérie d'une pluralité d'outils servant à creuser le sol.

  
Dans les trancheuses connues, afin de résister aux grands efforts auxquels

  
 <EMI ID=2.1> 

  
ment par soudure, ce qui interdit le remplacement aisé d'un outil brisé ou le changement de types d'outils par d'autres, en fonction de la nature du terrain rencontré par la trancheuse.

  
La présente invention remédie à cet inconvénient.

  
A cet effet, selon l'invention, la trancheuse comportai une roue munie d'outils à sa périphérie est remarquable en ce que lesdits outils sont fixés sur des portions amovibles de la jante de ladite roue.

  
 <EMI ID=3.1> 

  
porte au moins deux outils.

  
Avantageusement, chaque portion amovible de jante comporte d'une part au moins une partie de surface cylindrique coaxiale à ladite roue et sur la face convexe de laquelle est fixé au moins un outil et d'autre part une plaque orthogonale à ladite partie de surface cylindrique et solidaire de la face concave de celle-ci, ladite plaque se trouvant dans un plan parallèle & celui de la roue et étant rendue solidaire de la périphérie de celle-ci, de façon amovible.

  
.

  
 <EMI ID=4.1> 

  
laire dans laquelle puissent être introduites lesdites plaques des portions  <EMI ID=5.1> 

  
à des chevilles traversant ladite fente.

  
De préférence, lesdites plaques présentent la forme de portions d'un anneau plat qui s'appuient contre le fond de la fente.

  
La trancheuse peut comporter des frettes latérales tronconiques, convergeant vers l'extérieur de ladite roue, un racleur fixe étant disposé entre chaque

  
frette et la surface cylindrique coaxiale des portions amovibles de jante.

  
La fente est alors formée entre le flasque de roue et un anneau parallèle fixé sur l'une des frettes latérales, qui forme le fond de ladite fente.

  
Les outils pour terrain tendre peuvent être formés par des couteaux montés de façon amovible, grace à un emmanchement à coin et à vis, sur une base solidaire d'une surface cylindrique d'une portion amovible de jante.

  
En revanche les outils pour terrain dur ou pour béton peuvent être formés

  
 <EMI ID=6.1> 

  
large vers l'arrière que vers l'avant, lesdits picots étant disposé*! isolément les uns derrière les autres vers l'avant et par succession de groupes d'au moins deux vers l'arrière.

  
Les figures du dessin annexé feront bien comprendre comment l'invention peut être réalisée.

  
La figure 1 est une vue en perspective d'une roue de trancheuse selon l'invention. <EMI ID=7.1>  La figure 3 est une coupe radiale partielle de la roue des figures 1 et 2. La figure 4 est une vue correspondant à celle de la figure 2, les outils de tranchage étant otés. 

  
 <EMI ID=8.1> 

  
Les figures 5 et 6 montrent des supports d'outils selon l'invention.

  
La roue de trancheuse selon l'invention montrée par la figure 1, comporte

  
 <EMI ID=9.1>   <EMI ID=10.1> 

  
aux entrepreneurs de posséder deux matériels différents. 

  
 <EMI ID=11.1> 



   <EMI ID = 1.1>

  
trenches in the ground.

  
It is known that, in particular when laying underground cables or pipes, it is necessary to open trenches in the ground. In this

  
Indeed, machines are already known, called trenchers, comprising an automobile frame, for example a tractor, on which is mounted a wheel capable of being driven in rotation and provided at its periphery with a plurality of tools serving to dig the ground.

  
In known slicers, in order to withstand the great efforts to which

  
 <EMI ID = 2.1>

  
ment by welding, which prevents the easy replacement of a broken tool or the change of types of tools by others, depending on the nature of the ground encountered by the trencher.

  
The present invention overcomes this drawback.

  
To this end, according to the invention, the trencher included a wheel provided with tools at its periphery is remarkable in that said tools are fixed on removable portions of the rim of said wheel.

  
 <EMI ID = 3.1>

  
carries at least two tools.

  
Advantageously, each removable rim portion comprises on the one hand at least one part of cylindrical surface coaxial with said wheel and on the convex face of which at least one tool is fixed and on the other hand a plate orthogonal to said part of cylindrical surface. and integral with the concave face thereof, said plate being in a plane parallel to that of the wheel and being made integral with the periphery of the latter, in a removable manner.

  
.

  
 <EMI ID = 4.1>

  
area in which the said plates of the portions <EMI ID = 5.1> can be introduced

  
to pegs passing through said slot.

  
Preferably, said plates have the form of portions of a flat ring which bear against the bottom of the slot.

  
The slicer may include tapered side hoops, converging towards the outside of said wheel, a fixed scraper being arranged between each

  
hoop and the coaxial cylindrical surface of the removable rim portions.

  
The slot is then formed between the wheel flange and a parallel ring fixed to one of the side hoops, which forms the bottom of said slot.

  
Soft ground tools can be formed by knives removably mounted, thanks to a wedge and screw drive, on a base integral with a cylindrical surface of a removable portion of the rim.

  
On the other hand tools for hard ground or for concrete can be formed

  
 <EMI ID = 6.1>

  
wide towards the rear than towards the front, said pins being arranged *! separately one behind the other towards the front and in succession of groups of at least two towards the rear.

  
The figures of the appended drawing will make it easy to understand how the invention can be implemented.

  
Figure 1 is a perspective view of a trencher wheel according to the invention. <EMI ID = 7.1> Figure 3 is a partial radial section of the wheel of Figures 1 and 2. Figure 4 is a view corresponding to that of Figure 2, the slicing tools being removed.

  
 <EMI ID = 8.1>

  
Figures 5 and 6 show tool supports according to the invention.

  
The trencher wheel according to the invention shown in Figure 1, comprises

  
 <EMI ID = 9.1> <EMI ID = 10.1>

  
entrepreneurs to own two different equipment.

  
 <EMI ID = 11.1>
