Definitions
- the invention relates to a device for processing elongated deepening in the ground, especially for production a trench in the preamble of claim 1 specified genus.
- the milling device is transverse to the longitudinal direction of the trench back and forth which leads to that the trench is created wider than is actually necessary. This back and forth movement leads to an increased load of the excavator as a result of transverse forces acting on the Storage of the excavator arm (boom) act.
- EP 0 253 726 A1 describes a device for processing an elongated depression in the ground, especially for Making a trench with a motor driven one Half drums, tools on their circumference have described.
- the half drums are on one vertical bridge stored between the half drums is arranged.
- the axes of rotation of the half drums are slightly inclined downwards.
- the drive is a Hydraulic motor provided.
- the invention has for its object a device the genus specified in the preamble of claim 1 create that regarding the orbiting masses of the Milling tools optimized and directionally stable in operation.
- the main advantage of the invention is that that the rotating milling tools for the milling process only moved lengthways or into the ground must be necessary, but no transverse movement is necessary is.
- the inclination of the longitudinal axes of the milling tools is dimensioned such that the longitudinal axes to the Vertical axis at an angle between approx. 50 ° and 70 ° run.
- the milling tools essentially have the shape of a cone or truncated cone. Here corresponds to the angle of the surface of the cone, based on the base of the cone or truncated cone, the angle that the longitudinal axis of the milling tool to a vertical axis occupies.
- angles of both longitudinal axes are preferably the same large so that the vertical axis is an axis of symmetry for the Overall arrangement forms.
- A is particularly preferred Angle of the longitudinal axes viewed from 60 ° to the vertical axis.
- the wedge shape can also formed by the lateral surfaces of the milling tools be, namely in that the lateral surfaces of the Truncated cones on their front in the machining direction Include an angle ⁇ 180 °, preferably between 150 ° and 160 °.
- a hydraulic motor is particularly suitable as the drive motor. There is preferably a separate one for each milling tool Hydraulic motor provided on the shaft of the milling tool is put on immediately.
- Hydraulic motor provided on the shaft of the milling tool is put on immediately.
- a space-saving design to create is the milling tool at the base of the Truncated cone with a recess, the die Recess surrounding conical jacket at least partially Hydraulic motor covered. This also leads to the fact that Hydraulic motor protected within the surface of the cone lies.
- the motor or the hydraulic motors and the two milling tools preferably form a structural unit with a supporting part, which as an attachment to a construction machine, preferably an excavator that can be attached. That way the device of different construction machines depending on availability be used. For application on an excavator it is convenient to attach the implement to the back of a Pick up bucket or attach it there. At Such an arrangement can save considerable costs because the tooling times that usually occur for removing one tool and for picking up another Tools are eliminated. Due to the arrangement of the milling tools at the back of the bucket is the device when using the excavator bucket to pick up not obstructed by soil and favored on the other hand the weight of the excavator bucket when using the milling tool a vertical movement.
- Trench 1 shows a trench 1 in a soil 2, the trench 1 being essentially rectangular Cross section with a flat bottom 3.
- Trench 1 is a milling device 4, which on a movable arm 5 of a construction machine is attached and thus lowered into the ground or longitudinally movable in the working direction is.
- the milling device 4 comprises two arranged on a support member 6 Hydraulic motors 7, 8, on their motor shafts each a milling tool 9, 10 is attached.
- the milling tools 9 and 10 each have the shape of a truncated cone 19 and 20, which is centered on the shaft of the hydraulic motor 7 or 8, so that a longitudinal axis RA of Truncated cone 19, 20 the axis of rotation of the milling tool 9 or 10 forms.
- the longitudinal axes are RA to a vertical axis VA at an angle ⁇ 60 °, so that there is an angle ⁇ of the longitudinal axis RA compared to the bottom 3 of the trench 1 of 30 °.
- Angle ⁇ which the longitudinal axes RA enclose between them, is 120 °.
- the outer surface 11, 12 of the truncated cones 19, 20 are provided with a large number of milling cutters 18. Due to the longitudinal axis RA running obliquely to the floor 3 are the truncated cone shapes 19, 20 of the milling tools 9 and 10 aligned such that their lateral surfaces 11, 12th are aligned parallel to the floor 3.
- the lateral surfaces 11 and 12 of the milling tools 9 and 10 are located on their side adjacent to the floor 3 with their respective Base 13, 14 of the truncated cone shape 19, 20 while maintaining a working game 15 so together that there is a continuous working plane AE parallel to the floor 3 results.
- the truncated cones 19, 20 with their lateral surfaces 11, 12 can be close to each other at the base 13, 14 and the truncated cones are used to achieve a compact design 19, 20 at their base 13, 14 with a recess 16, 17 provided, in which the hydraulic motor 7, 8 at least is partially included, so that the lateral surface 11, 12th of the cone 19, 20 partially covers the hydraulic motor 7, 8.
- the truncated cones 19, 20 face in the respective Edge region of the trench 1 directed upper sides 13 'and 14' on.
- FIG. 2 shows the side view of an excavator bucket 21, a milling device 24 on the rear 22 thereof is arranged.
- the milling device 24 comprises a supporting part 23 for the hydraulic motors not visible in FIG. 2 and the milling tools, of which only due to the side view a milling tool 25 is shown.
- the top 13 'of the truncated cone 19 based on the Base 13 of the milling tool 25, arranged off-center, see above that the working plane running parallel to the floor 3 AE according to FIG. 1 results.
- FIG. 3 shows an excavator 26, on the arm 27 or Boom a combined device from excavator bucket 21 and milling device 24 is attached.
- Excavator bucket 21 When folded in Excavator bucket 21 is the milling tool 25 on the Soil 2 directed so that the trench 1 can be processed can.
- the milling tool 25 loosens the soil 2 in the width intended for the trench 1, a discharge of the soil from the trench is with the milling device 24th however not possible.
- the direction of work is with the arrow S denotes.
- the means is extracted the milling device 24 loosened soil through the bucket 21, which picks up the loosened soil, so that this by lifting the arm 27 and pivoting it sideways deposited outside the trench 1 or on a truck can be dropped for transport.
- FIG. 5 shows the top view of the milling device 4 with the two milling tools 9 and 10, which as in Fig. 1 shown by means of a support member 6 arranged Hydraulic motors 7, 8 are driven.
- the longitudinal direction the processing or digging is indicated with S, see above that it also becomes clear that Fig. 5 is a view is in the vertical direction.
- the Have axes of rotation RA of the two milling tools 9, 10 one to the longitudinal axis of the trench or the working direction S. Angle ⁇ 1 ⁇ 90 °. This will create a wedge shape in Working direction S is formed, which leads to the fact that Force vectors are directed towards the center of the support part 6 and thus self-centering or Effect directional stabilization.
- FIG. 6 is also a plan view of the Milling device 4 shows.
- the milling tools 9, 10 so strongly angled to Longitudinal direction S that the lateral surfaces 11, 12 of the frustoconical milling tools 9, 10 on the side in Working direction S include an angle ⁇ , which in Embodiment is approximately 160 °.
- This angle ⁇ should expediently be in the range between 150 ° and 160 ° lie.
