Definitions

  • the present invention relates to a new device for fixing the engine blocks of a milling device intended for digging trenches in the ground.
  • Such milling devices require relatively frequent disassembly of the engine blocks, which constitutes a significant loss of money and time due to the difficulties of access to the central part of the device between the two engine blocks.
  • the present invention relates to a new device for fixing the engine blocks of this type of device which allows them to be assembled and disassembled quickly and simply without the quality of the fixing being affected.
  • the subject of the present invention is a device for fixing a motor block of a milling device intended for digging trenches in the ground, of the type comprising at its lower part two motor blocks each supporting two coaxial half-drums provided of teeth mounted on a central core provided with a horizontal sole at its upper part, characterized in that the fixing of the sole of the central core to the lower part of the device is obtained by the fact that the end of the sole directed towards the center of the device has on its lower face a bevelled shape which engages against a support plate of corresponding shape which is integral with the lower part of the milling device, said sole being forcibly pushed towards the center of the device and being held at its other end against the lower part of the device, for example by means of bolts.
  • the lower part of the milling device is constituted by a bottom plate which has in the center of its lower face a support plate forming stops for the bevelled ends of the flanges of the blocks -motors.
  • This bottom plate also has two longitudinal openings arranged in the axis of the cores of the engine blocks, the soles of the engine blocks having bosses which during mounting come to engage in said longitudinal openings.
  • a bolt arranged in the thickness of the bottom plate makes it possible to exert a sufficient horizontal force on the end of the boss of the sole concerned in order to push the latter towards the support plate while allowing the tightening of vertical bolts which firmly join the sole to the bottom plate of the device in the vicinity of the end of the sole which is located on the side of the device.
  • central cores 1 and 2 which each support an assembly constituted by the motor device and the cutters which for simplicity, have not been shown in the drawing.
  • the strawberries are constituted by two half-drums provided with teeth at their periphery which are rotated around the axes 3 by a motor device.
  • Each core 1,2 is provided at its upper part with a horizontal sole 4,5 which allows the fixing of the engine block to the lower part of the milling apparatus, which is constituted in the embodiment described by a plate steel bottom 6.
  • the ends of the flanges 4 and 5 which are directed towards the center of the device each have a bevel 7 which engages against a stop 8 of corresponding shape made on a support plate 9 which is attached to the bottom of the bottom plate 6.
  • the shape of the surfaces 7 and 8 is such that when a sole plate 4.5 is pushed in the direction of the center of the apparatus, its inner edge is wedged against the support plate while being strongly applied against the bottom plate 6.
  • the bottom plate 6 which constitutes the lower part of the milling apparatus has two longitudinal openings 10 and 11 inside which engage bosses 12 and 13 of elongated shape which are produced on the upper surface of the soles in the axis of webs 1 and 2.
  • a bolt 14 which is engaged in a horizontal tapped hole, so that the end of the bolt 14 comes to bear on the side of the boss 12,13 to push the block corresponding motor towards the center of the device.
  • the bolt 14 is then tightened, which pushes the engine block towards the center in such a way that the internal end of the sole plate 4.5 is jammed by the action of the inclined surfaces 7.8 of the support plate 9. .
  • FIG. 4 is a perspective view corresponding to FIGS. 1 to 3.
