  "Malaxeur"

  
 <EMI ID=1.1> 

  
laxeur à béton muni d'une cuve à malaxer sensiblement cylindrique qui est supportée rotative autour d'un axe coïncidant avec la ligne médiane, dans le milieu d'une barre en forme d'U suspendue basculairement à deux tourillons, ladite cuve étant munie d'une couronne dentée qui s'engrène avec un pignon attaché sur un arbre prévu dans l'un desdits tourillons.

  
L'invention se rapporte spécialement à un seul dispositif agitateur qui est actionné par la rotation de la cuve, ou bien, qui est commandé séparément ou conjointement avec la cuve.

  
Suivant l'invention,il a été prévu à ce but, co-axialement avec l'axe de rotation de la cuve, une roue dentée qui est reliée fixement à la barre en forme d'U, ou qui est rotative par-rapport à celle-ci, laquelle roue dentée s'engrène avec plusieurs roues dentées attachées sur des arbres de dispositifs agitateurs arrangés rotativement dans le fond de la cuve. 

  
Le dessin ci-annexé représente un mode de réalisation de l'invention.

la fig.2 est une vue en élévation selon la flèche dans la fig.l, tandis que la fig.3 représente une vue en élévation des dispositifs agitateurs dans la cuve.

  
La cuve 1 consiste en une partie cylindrique avec fond, au bord supérieur de laquelle il est raccordé une partie de paroi

  
de forme demi tronconique, paroi qui pendant le basculement

  
sert pour la décharge de la matière.

  
La cuve est munie à son côté inférieur d'un tourillon 2, soudé dans le fond de la cuve et dont la ligne médiane coïncide avec la ligne médiane de la cuve. Ce tourillon 2 est supporté dans un trou ménagé dans une pièce 3, dans lequel il est logé un appui sphérique axial 4 pour supporter le poids de la cuve. La pièce 3 est attachée dans un trou ménagé dans la barre en forme d'U 5 dont les bouts sont munis tous les deux d'un tourillon trans&#65533;

L'un des tourillons 6 est muni d'un trou dans lequel un arbre 9 est logé rotativement, arbre dont le bout qui s'étend du côté de la cuve est muni d'un pignon 10 qui s'engrène avec une couronne dentée 11 disposée autour de ladite cuve. Sur l'autre bout qui dépasse le support 7 il est fixé une poulie à courroie
12.

  
Autour du bout supérieur de la pièce 3 il a été prévu une roue dentée 13 qui peut être attachée fixement à ladite pièce 3,

  "Mixer"

  
 <EMI ID = 1.1>

  
concrete laxer provided with a substantially cylindrical mixing tank which is rotatably supported about an axis coinciding with the center line, in the middle of a U-shaped bar suspended tiltably from two journals, said tank being provided with 'a ring gear which meshes with a pinion attached to a shaft provided in one of said journals.

  
The invention relates especially to a single agitating device which is actuated by the rotation of the tank, or, which is controlled separately or together with the tank.

  
According to the invention, it has been provided for this purpose, co-axially with the axis of rotation of the tank, a toothed wheel which is fixedly connected to the U-shaped bar, or which is rotatable with respect to the latter, which toothed wheel meshes with several toothed wheels attached to shafts of agitating devices arranged rotatably in the bottom of the tank.

  
The accompanying drawing represents an embodiment of the invention.

  
 <EMI ID = 2.1>

  
fig. 2;

  
Fig.2 is an elevational view along the arrow in Fig.l, while Fig.3 shows an elevation view of the agitator devices in the tank.

  
The tank 1 consists of a cylindrical part with a bottom, to the upper edge of which a wall part is connected

  
of semi-frustoconical shape, wall which during tilting

  
serves for the discharge of matter.

  
The tank is provided on its lower side with a journal 2, welded to the bottom of the tank and the center line of which coincides with the center line of the tank. This journal 2 is supported in a hole made in a part 3, in which an axial spherical support 4 is housed to support the weight of the tank. The part 3 is attached in a hole made in the U-shaped bar 5, the ends of which are both provided with a trans journal &#65533;

  
 <EMI ID = 3.1>

  
supported tiltably in supports 7 provided at the upper ends

  
 <EMI ID = 4.1>

  
One of the journals 6 is provided with a hole in which a shaft 9 is rotatably housed, the shaft of which the end which extends from the side of the tank is provided with a pinion 10 which meshes with a toothed ring 11 arranged around said tank. On the other end which exceeds the support 7 is fixed a belt pulley
12.

  
Around the upper end of part 3 there has been provided a toothed wheel 13 which can be fixedly attached to said part 3,

Claims

conical toothed wheels, the latter having for object to set the agitator device in motion when the tank is in inactive position. With the toothed wheel 13 it meshes three wheels 14, attached to the shafts 15 arranged rotatably in sockets 16 provided on the bottom inside the tank. On the end which extends above the sockets there is attached to each shaft 15 a paddle means 17. Figure 1 of the drawing shows two different embodiments of the agitator members.

When the bowl is rotated by means of the belt pulley 12, the paddles 17 will begin to spin, thus agitating the contents of the tank.

If it is desired to set the mixing members in motion, while the tank remains stationary and the shaft 9 is not actuated, the toothed wheel 13 can be arranged rotatably around the part 3 and the toothed wheel can be fixedly connected. to a bevel gear which can be controlled by means of a bevel gear which meshes with it. The shaft of this bevel gear can be controlled by a shaft arranged co-axially with the journals 6, or else by the shaft 9, which will then cause the tank and the agitating devices to be controlled by this shaft.

It is also possible to work with a toothed wheel 13 arranged <EMI ID = 6.1>
