Definitions
- the present invention relates to a strawberry drum usable in particular for the realization of vertical trenches in hard or very hard floors.
- drilling rigs most often called strawberries and which are in themselves of a well known type.
- Such drilling rigs are described in particular in European patent application No. 1,231,327 filed in the name of the plaintiff.
- These devices are essentially constituted by a frame suspended from the lower end of a muffle.
- the frame of the cutter is equipped at its lower end with two pairs of milling drums each driven by a motor preferably hydraulic.
- milling tools different types are attached to the shell of the strawberry drum.
- milling tools When you want to make the trench in hard or very hard soil, milling tools often consist of rollers or knurling wheels freely mounted in rotation on the periphery of the drum shell. These rollers are fitted with buttons for punching hard ground and thus to carry out drilling.
- mounting the milling tools on the drum shell raises certain difficulties.
- each drum or more precisely each drum ferrule 14a, 16a has a certain width I along the direction of the axis of rotation X-X 'of the drums.
- the milling tools mounted on the ferrules allow drilling on a width L at least equal to the width I of the ferrules.
- An object of the present invention is to provide a drum milling which effectively allows the trench to be milled over the entire width of the milling drum ferrules, while obtaining a tool yield much higher than that obtained by technique described above.
- the first rollers being substantially cylindrical or slightly barrel-shaped, an optimal yield of the tool.
- the first drums being substantially cylindrical or slightly barrel-shaped, an optimal yield of the tool.
- the first rollers have axes which are mounted at each of their ends in bearings fixed on the outer wall of the ferrules. We thus obtain no only optimal drilling efficiency, but also mechanical stress also optimal due to the presence of bearings at both ends of the axes of rotation of these first rolls.
- the drum 20 firstly comprises a cylindrical shell 22 which is rotated around its axis of revolution X-X 'by a motor not shown secured to the core 24 of the cutter.
- Pieces mechanical such as 26 realize the rotational transmission between the output of the drive motor and the ferrule 22.
- tools 28 which consist of a single roller which will be described later in more detail and, on the other hand, milling tools 30 consisting of a pair of second milling rollers.
- the milling tools 28 or 30 are angularly regularly distributed on the ferrule 22 around its axis of rotation X, X ' making angles between them at the center b.
- others distributions of the two types of tools could be implemented.
- the tool 28 consists of a roller or wheel 36 whose side wall 36a is provided with cutting elements such buttons 38.
- the side wall 36a of the roller can be cylindrical. It can also be a surface of revolution generated by a generator which has the shape of a curve (portion of ellipse) symmetrical with respect to the median plane of the roller.
- Roller 36 is rotatably mounted around an axis 40 which is substantially parallel to the axis X'-X of rotation of the ferrule 22.
- the axis 40 is supported by two bearings end 42 and 44 which are fixed to the external face 22a of the shell by supports 46 and 48.
- the active width of the roller 36 referenced is necessarily less than the width I of the ferrule 22. However, this width is greater than half the width I of the shell and, from preferably greater than 2/3 of this width.
- the axes 40 of the rollers may not be parallel to the axis XX 'of the ferrule 22, but make an angle with it reduced by around 1 to 10 degrees to allow slight shifting of the buttons 38 during rotation of the roller 36. In the case of more terrain tender, this angle can reach 45 degrees.
- the second milling tool 30 consists of a pair of milling rollers or knurled wheels referenced 50 and 52.
- Rollers 50 and 52 have a side wall 50a, 52a which is substantially cylindrical.
- Each roller 50, 52 is rotatably mounted around a shaft 54, 56 which is cantilevered respectively on a bearing 58, 60 fixed on the outer wall of the shell 22 by supports 62 and 64.
- the axes of rotation 54 and 56 are parallel to the axis XX 'of rotation of the ferrule 22.
- the second rollers 50 and 52 have axes parallel to the axis XX 'of the shell.
- the rollers 50 and 52 of the same pair occupy the same angular position relative to the axis XX 'of the ferrule and are arranged substantially symmetrically relative to the median plane PP' of the ferrule, orthogonal to the axis X-X . More specifically, the rollers 50 and 52 are arranged so that the envelope E and E 'of these rollers during the rotation of the ferrule 22 extends at least to the end faces 32 and 34 of the ferrule or go slightly protruding from its faces.
- the width e of these rollers is such that their zone of action partially overlaps that of the first rollers 36 so that, when drilling the ground, there is an overlap between the zone drilled by the rollers 36 and that which is drilled by the rollers 50 and 52.
- the width I of the rollers 50 and 52 can be reduced. It is at most equal to 1/4 of the width of the shell and preferably not more than 1/6 th .
- the width L actually drilled by the milling drum is at least equal to the width I of the drum shell.
- the width of the ferrule can be between 25 and 75 cm.
- the most much of the drilling is carried out by rollers 36 whose axes of rotation are mounted in two end bearings 42 and 44.
- the second rollers 50 and 52 do not have to develop than a much more limited drilling force due to the presence of rollers 36. This is why the rollers 50 and 52 can be mounted in overhang on bearings 58 and 60. Despite this cantilever mounting and thanks to the limited efforts applied to these rollers, these can bear the constraints applied to them.
- rollers 50 and 52 on their side walls 50a and 52a are fitted with buttons such as 66.
- 66 'buttons can also be provided on the external sides 50b and 52b of the rollers 50 and 52 in their peripheral part. We could also consider equipping all outer end faces 50b and 52b of the rollers 50 and 52 of 66 'buttons.
- first rollers 36 can be centered by relative to the ferrule 22.
- the middle of the axis of rotation of the rollers is substantially arranged in the median plane of the ferrule 22 orthogonal to the axis of rotation XX 'thereof.
- the first rolls 36 can also be staggered.
- the backgrounds axes of the rollers 36 are alternately arranged on one side and the other of the median plane of the shell 22 orthogonal to its axis of rotation.
