Definitions

  • the present invention relates to a device for fixing the milling drums to an apparatus intended for digging trenches in the ground.
  • milling devices are required to work in soils of very variable natures, such as alluvial soils which offer only a low resistance to milling or even compact rocks which are extremely hard.
  • the milling apparatus must therefore be able to be adapted to the different working conditions, for example by varying its speed of rotation or the torque exerted on the cutters, but also by using different cutters, for example by their width, or by the nature and the number of their tools.
  • the present invention relates to a device which makes it possible to effect this change in a simple and rapid manner while allowing extremely reliable securing of the milling drum to its motor device.
  • the subject of the present invention is a device for fixing the milling drums to an apparatus intended for digging trenches in the ground, characterized in that the driving device comprises a turntable arranged perpendicularly to its axis and to the end of that -this, plate which has on its periphery a convex polygonal shape, while the milling drum is provided with a flange comprising a central recess of concave polygonal shape corresponding to the convex polygonal shape of the plate of the motor device and of slightly larger dimensions , holding organs joining the milling drum to said plate so that the rotation of the milling drum by the plate is effected by means of the aforementioned polygonal surfaces which come to engage one against the other.
  • the flange of the milling drum is connected to the plate of the motor device by bolts arranged between the tops of the polygonal surfaces which ensure the drive of the milling drum.
  • the periphery of the plate of the motor device comprises a convex frustoconical surface which engages in a concave frustoconical surface of corresponding shape integral with the milling drum to ensure the rigorous positioning of the milling drum relative to the motor device.
  • the positioning and in particular the coaxiality of the milling drum with respect to the axis of the motor device is ensured by the two frustoconical surfaces which engage one on the other.
  • connection of the plate to the motor device with the flange of the milling drum is then ensured by bolts under conditions such that they do not take a significant part in the transmission of the milling torque, for example by the fact that they pass through a orifice whose dimensions are sufficiently large.
  • the polygonal surfaces are hexagons which have the advantage of effectively fulfilling the torque transmission function while leaving enough room to place between their vertices the six bolts which secure the drum of milling on the motor device plate.
  • non-point polygonal surfaces with generatrices parallel to the axis of the drum, but by giving them a shape of trunks of pyramids, which allows them to simultaneously ensure the positioning function and that of rotary drive, in which case the frustoconical surfaces become useless.
  • the drive device supports an end ring 1 which is integral with the vertical core which supports the assembly constituted by the drive device and the milling drums.
  • This end ring 1 supports a bearing 2 which maintains an internal ring 3, to which a plate 4 is fixed by bolts 5
  • the crown 3 has an internal toothing which engages in the internal toothing of a wheel 6 which also includes a central orifice provided with an internal toothing which engages in the external toothing of the shaft 7 of the drive device.
  • the motor device rotates the plate 4 which is positioned by the bearing 2, and this while ensuring a certain play in the positioning of the shaft 7 relative to the plate 4.
  • the shaft 7 can drive the crown 3 and the plate 4 via intermediate pinions or a planetary gear.
  • FIG. 2 shows the plate 4 on which the milling drum 8 is fixed, in accordance with the invention.
  • the plate 4 has on its periphery an external polygonal surface 9 whose generatrices are parallel to the axis of the drive device.
  • the portion 8a of the milling drum 8 has at its inner periphery a polygonal surface 10 of shape corresponding to that of the polygonal surface 9, but of very slightly larger dimensions so that the milling drum 8, 8a, can be easily engaged against the plate 4.
  • the portion 8a of the milling drum 8 is secured to the plate 4 by bolts 11 which are screwed into threaded holes of the plate 4 and which traverse the portion 8a of the milling drum 8 via orifices whose dimensions are sufficient to ensure that the drive torque is transmitted by the sides of the polygonal surfaces 9 and 10 when these sides come into contact with one another and not by the shearing of the bolts 11.
  • the periphery of the plate 4 has a frustoconical surface 12 whose axis corresponds to the axis of rotation of the plate 4, the apex of the cone of this surface being located towards the outside of the milling apparatus.
  • the milling drum 8 has, for its part, a concave frustoconical surface of corresponding shape 13 which, by coming to bear against the frustoconical surface 12, ensures an exact positioning of the milling drum 8 on the motor device.
  • the milling drum 8 In order to mount the milling drum 8, the latter is engaged around the motor device by bringing the concave frustoconical surface 13 into contact with the convex frustoconical surface 12 by arranging that the orifices of the portion 8a of the drum are in a position such as to enable the screw bolts 11 which ensure the provisional retention of the drum 8 of the driving device.
  • the fixing and dismantling of the milling drums is carried out in a particularly simple manner, which makes it possible, without loss of time, to change them each time the characteristics of the ground so require. .
  • the surfaces 9 and 10 ensure both the axial positioning of the drum 8 and its drive in rotation.
