Definitions

  • the present invention relates to a milling device intended for digging trenches in the ground comprising a new device for fixing the engine blocks.
  • 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 an apparatus of this type which comprises a new device for fixing the engine blocks which makes it possible to carry out their mounting and dismounting quickly and simply without the quality of the fixing being affected thereby.
  • the subject of the present invention is a milling device intended for digging trenches in the ground of the type comprising at its lower part two engine blocks each supporting two coaxial half-drums provided with teeth, each of the engine blocks being provided with a device fixing comprising a central core provided at its upper part with a horizontal sole, characterized in that the fixing of each sole of the central core to the lower part of the milling apparatus is obtained by the fact that the end of the sole directed towards the center of the device has on its underside 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 webs 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.

Claims (5)

1. Fräsvorrichtung zum Ausnehmen von Gräben im Boden, derjenigen Art, die an ihrem unteren Teil mit zwei Motorblöcken versehen ist, die jeder zwei koaxiale mit Zähnen versehene Halbtrommeln aufweisen, die jeder eine Befestigungseinrichtung aufweisen, die von einem zentralen Steg (1,2) gebildet ist, der an seinem oberen Teil mit einer horizontalen Fussplatte (4,5) versehen ist, dadurch gekennzeichnet, dass die Befestigung jeder Fussplatte (4,5) des zentralen Stegs (1,2) an dem unteren Teil (6) der Fräsvorrichtung dadurch erzielt wird, dass das gegen das Zentrum der Vorrichtung geführte Ende der Fussplatte (4,5) auf seiner unteren Fläche eine schräg angeschnittene Form (7) aufweist, die mit einer an dem unteren Teil (6) der Fräsvorrichtung angebrachten Stützplatte (9) entsprechender Form in Eingriff kommt, wobei die genannte Fussplatte (4,5)an ihrem anderen ende mit Kraft in Richtung der Mitte der Vorrichtung, zurückgedruckt und gegen den unteren Teil (6) der Vorrichtung, beispielsweise mit Hilfe von Bolzen, gehalten ist.
2. Vorrichtung nach Anspruch 1, dadurch gekennzeichnet, dass ihre untere Teil eine Grundplatte (6) aufweist, die in der Mitte ihrer Unterseite eine Stützplatte (9) trägt, die Widerlager (8) für die schräg angeschnittenen Enden (7) der Fussplatten (4,5) der Motorblöcke bildet.
3. Vorrichtung nach Anspruch 2, dadurch gekennzeichnet, dass die Grundplatte (6) zwei Längsöffnungen (10,11) aufweist, die in der Ebene der Stege (1,2) der Motorblöcke angeordnet sind, während die Fussplatten (4,5) Vorsprünge (12,13) tragen, die bei der Montage der Motorblöcke mit den Längsöffnungen (10,11) in Eingriff kommen.
4. Vorrichtung nach Anspruch 2, oder 3, dadurch gekennzeichnet, dass die Grundplatte (6) an jedem ihrer Enden einen Bolzen aufweist, der in eine horizontales Gewindeloch eingreift, wobei es das Ende des Bolzens erlaubt, eine horizontale Kraft auf den an der Fussplatte (4,5) angebrachten Vorsprung (12,13) derart auszuüben, dass der Motorblock gegen die Mitte der Fräsvorrichtung gedrückt wird.
5. Vorrichtung nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, dass die äusseren Querenden der Fussplatten (4,5) mittels Bolzen (15), die in die Grundplatte (6) geschraubt sind und die durch in den Fussplatten (4,5) parallel zu den Stegen (2) angebrachte Längsöffnungen hindurchragen, an der Grundplatte (6) der Fräsvorrichtung befestigt sind.
