Definitions

  • the invention relates to a soil cultivation machine or a method for processing ground or traffic surfaces as a self-propelled machine or attachment according to the preamble of claim 1 and 10, respectively.
  • Such tillage machines are used for material processing, namely, for example, the stabilization of unsuitable soils, the pulverization of asphalt floors, and the recycling of bonded or unbound road surfaces.
  • material processing namely, for example, the stabilization of unsuitable soils, the pulverization of asphalt floors, and the recycling of bonded or unbound road surfaces.
  • a powdered or liquid binder in the soil in order to increase its installation capacity and load capacity.
  • the known tillage machines have a rotating in a mixing chamber milling / mixing roller, which is arranged vertically adjustable under a milling / mixing roller enclosing, fixed to the machine frame roller housing.
  • the tillage machine may be self-propelled or an attachment. Examples of such machines are in the WO 96/24725 , of the WO 2005/054578 or the EP 2218823 A described.
  • the necessary processes take place, adapted to the respective application, such as e.g. Mincing the soil, adding binders, mixing and distributing added materials.
  • a known tillage machine as for example in Fig. 1 is shown, it is already known to provide front and rear pivotable roll flaps on the roll housing to limit the exit of the milled or to be mixed and / or comminuting material during the machining process.
  • the position of the roller flaps is dependent on the task or the nature of the substrate and the desired work result.
  • the grading curve ie the size distribution of the milled pieces of material can be influenced.
  • the setting of the roller flaps takes place in a pivoting movement about a transverse to the working direction and parallel to the axis of the milling / mixing roller pivot axis.
  • the swivel angle of the front roller flap is manually adjustable by the machine operator and remains substantially constant for the entire machining process.
  • the roller flap is usually not on the ground.
  • the WO 2012/016573 , the EP 2025812 and the US 2013/0341997 concern road milling machines in which a stripping device is arranged in the direction of travel behind the milling drum, which engages in milling operation with a scraper blade in the milling track generated by the milling drum and the roller box seals against the milling ground to the rear.
  • the scraper blade can be height-adjustable linearly upwards. Pivoting is not possible during operation due to a locking device.
  • the stripping device must not be able to pivot during operation, since otherwise it will rotate from that in the roller housing Milling material could be pressed. A pivoting of the stripping device is only possible when the machine is at a standstill with the engine off to allow access to the tools of the milling drum during maintenance and repair work.
  • the invention is therefore, starting from the above-mentioned prior art, the object of a soil tillage machine, and to provide a method for milling soils and traffic areas, in which a reproducible crushing of the soil or the traffic area with different tasks and conditions can be reached, in which the average grain size of the fragments and the width of the distribution can be influenced.
  • roller flap is at least two parts and has at least one upper part and one lower part, wherein at least one part is pivotally and at least one further part telescopically linear or arcuately adjustable. Due to the extended adjustment of the roll flap can be improved by the flap position not only the average size of the fragments, but also the homogeneity of the size distribution and especially larger fragments are avoided in the milled.
  • the division of the roll flap in at least two parts, in which one telescopically linear or arcuately adjustable and another is pivotable, allows the roll flap during the milling process, especially in variable positions of the milling drum within the roll housing always in an optimal for the respective working process distance from the Irrespective of whether the roller flap rests on the floor or not.
  • adjustment of the front roller shutter is realized by a swing motion combined with a linear or arcuate movement.
  • the invention is applicable not only to soil stabilizers and cold recyclers, but also to other construction machines having a milling drum in a milling drum housing, e.g. Road milling, Surface Miner, especially when the grading curve of the work result is important, the milling drum is height adjustable via the height adjustment of the machine frame.
  • the pivot angle and / or the position of the telescopically adjustable part of the roll flap depending on the current milling depth is controlled such that the distance between the roll flap and milling / mixing roll variably adjustable, z. B. minimized is.
  • the distance of the lower part or the lower edge of the lower part of the milling / mixing roller of importance is controlled.
  • the flexible adjustment of the roll flap enables the grading curve, i. adjust the average grain size and the grain size distribution of the milled material over the arbitrary distance between the front roll flap and milling / mixing roll reproducible.
  • the current position of the roll flap, or the upper and lower part of the roll flap is detected by measurement to allow control of the positions.
  • the pivot angle of the pivotable part and / or the position of the telescopically adjustable part of the roll flap depending on the current milling depth is adjustable so that the lower edge of the roll flap can be used as hold-down.
  • the milling / mixing roller can gradually process and crush the larger debris and floes in the hold down position.
  • a controller automatically controls the pivoting angle of the pivotable part of the roller flap and the position of the telescopically linearly or arcuately adjustable part, at least as a function of the current milling depth.
  • an exchangeable breaker bar is arranged on the lower edge of the lower part.
  • a plurality of juxtaposed, preferably evenly spaced, e.g. skid-shaped sliding shoes are arranged.
  • Sliding shoes and breaker bar can also be used simultaneously, in particular can be attached to the lower end of the roller flap sliding shoes and projecting above the sliding blocks a breaker bar in the direction of the milling / mixing roller.
  • the shoes can favor the breaking process, especially in runner shape, and z. B. limit the extent of the fragments in the transverse direction of the working direction. Material lying in front of the roller housing can enter the roller box through the clearances between the runners, even if this is guided over the floor as a hold-down device.
  • the roller flap against the floor or traffic area with a predetermined contact pressure is pressed.
  • the contact pressure can be applied by the weight or by a hydraulically variably adjustable pressure, for example.
  • the upper part is pivotable and the lower part is telescopically linear or arcuately adjustable, wherein the lower part is adaptable to an existing in the ground bank or uneven ground relative to the upper part.
  • the lower part can be in one or more parts and can be adapted to a possibly uneven ground surface or a milling track intentionally deviating from the horizontal.

  • Fig. 1 shows one from the WO 2005/054578 known tillage machine 1 for working lanes or stabilizing insufficiently sustainable floors 14, or recycling of road surfaces, with a cover layer 5 and an underlying support layer 7, with a supported by a chassis 2 machine frame 4.
  • the chassis 2 has two rear and front wheels. 6 , 8, which are height-adjustable to lifting columns 12 are fixed and which can be raised and lowered independently or synchronously with each other. It is understood that instead of the wheels 6, 8, other drive means such as track tracks, may be provided.
  • the lifting columns 12 are attached to the machine frame 4.
  • Both suspension axles formed from the front and rear wheels 6, 8 can be steerable.
  • a control station 10 On the machine frame 4 is above the front wheels 8 or in front of the front wheels 8 as in Fig. 1 and 2 a control station 10 arranged for an operator visible.
  • control station 10 is arranged in front of the front wheels 8 or in front of the axles of the front wheels 8 and can be moved out beyond the outer machine boundary on at least one side of the machine.
  • the milling / mixing roller 20 enclosing roller housing 28 may be fixedly hinged to the machine frame 4, so that a height adjustment of the roller housing 28 can be done solely by the lifting columns 12 for the wheels 6 and 8.
  • the in the direction of travel 50 preferably in the counter-rotating milling / mixing roller 20, the axis of which extends transversely to the direction of travel, is mounted relative to the machine frame 4 pivotally about a pivot axis 34, so that they from a rest position, as in Fig. 1 shown in a milling position as in the other Fign. represented, with the help of both sides arranged pivot arms 42 is pivotable.
  • Each pivot arm 42 is mounted at one end in the machine frame 4 and receives at its other end the storage of the milling / mixing roller 20.
  • the milling / mixing roller 20 is, for example, with in Fig. 9 provided milling tools 22 provided to edit a floor or a traffic area 14 can.
  • the roller housing 28 rests on the ground surface 3 of the floor 14 to be machined, or is held at a short distance from the floor 14, while the milling / mixing roller 20 continues depending on the given milling depth is pivotable downwards.
  • a lateral boundary of the roller housing can be done by moving side plates.
  • the mixing chamber volume can also be influenced by additional internally adjustable flaps in the roll housing, which basically consist of the DE 10 2010 050 831 are known.
  • additives can be introduced, for example via a spray 18 and mixed with the milled material.
  • the milling / mixing roller 20 has at its front and rear edge pivotable roller flaps 27,25.
  • the front in the direction of travel 50 roll flap 27 is slightly raised in the prior art during operation, so that it does not rest on the ground, and the rear in the direction of travel 50 roll flap 25 can be used as a scraper blade.
  • the maximum lowering of a non-rigidly fixed to the machine frame 4 roller housing 28 can be determined by a limiting device.
  • roller housing 28 In such a roller housing 28 is therefore provided that this rests floating on the bottom surface 14.
  • the roller housing 28 is fixedly attached to the machine frame 4, as already mentioned.
  • FIGS. 2 and 3 each show a conventional solution with a front pivotable roll flap 27 which is pivotable about a parallel to the milling / mixing roll 20 pivot axis 38 on the roll housing 28.
  • Fig. 2 shows the position of the milling / mixing roller 20 in the mixing chamber 24 at a low cutting depth
  • Fig. 3 the position with a large milling depth. The different positioning results from the fact that the milling / mixing roller 20 is moved under the roller housing 28 along a trajectory 36, which is determined by the pivotal movement of the pivot arms 42 about the pivot axis 34.
  • the distance A between the lower end of the roll flap 27 and the milling / mixing roll 20 is very different, so that in the case of a small cutting depth by milling in the opposite direction large clods and fragments of the cover layer 5 can break out.
  • the floes and large debris caught by the milling / mixing roll 20 can produce undesirable forces on the milling / mixing roll 20 or on the roll housing 28 exercise. This can lead to increased wear, or reactions of the tillage machine are generated, which rock or raise the machine, so that the machining process is disturbed and the quality of the work result is impaired.
  • there is the disadvantage that the homogeneity of the comminution of the milled material 16 is greatly impaired by the large fragments resulting from the breaking-up of clods.
  • the problem is both with a large depth of cut and increases significantly in the case of a small depth of cut.
  • Fig. 4 shows a first embodiment according to the invention, in which the roller flap 27 occupies a suitable position for soil stabilization.
  • the roll flap 27 is designed at least in two parts and has in the Fig. 4 a pivotable upper part 30, which is pivotable about the pivot axis 38, and a linearly displaceable along the upper part 30 lower part 32.
  • the upper part 30 and the lower part 32 need not necessarily be rectilinear, but may also have a cross-sectional shape adapted to the diameter of the milling / mixing roller 20.
  • front roller flap 27 can be positioned differently with its lower edge or with its relative position to the milling / mixing roller 20 as a function of the milling depth or the position of the milling drum axis along the path curve 36.
  • Fig. 5 shows the flap position of the front roller cap 27 in the case of a cold recycling process with large milling depth.
  • the roller flap 27 is brought with its lower edge very close to the milling / mixing roller 20, wherein at the same time the lower edge of the lower part 32 rests on the cover layer 5. In this way, the lower edge of the lower part 32 can be used simultaneously as hold-down, whereby the risk of floe formation is additionally reduced.
  • Fig. 6 shows an alternative embodiment - in a cold recycling process, for example, with low depth of cut, in which the lower edge of the base 32 maintains a distance from the bottom surface 3, but at the same time the distance to the milling / mixing roller 20 is minimized.
  • the penetration of larger fragments by the small distance between the roller flap 27 and the milling / mixing roller 20 is securely excluded, so that the size distribution of the fragments in the mixing chamber 24 is largely homogenized.
  • FIGS. 5 and 6 By the embodiments of the FIGS. 5 and 6 is reliably excluded that larger fragments or clods may enter the mixing chamber 24 and the milling / mixing roller 20 or the roller housing 28 may damage or affect the milling process.
  • Fig. 7 shows an alternative embodiment in which at the lower edge of the lower part 32 in addition a breaker bar 44 is arranged, which protrudes from the lower edge of the lower part 32 in the direction of the milling / mixing roller 20. Also in this case can be reliably prevented that larger fragments, which may occur in particular by the counter-milling, can enter the mixing chamber 24. Emerge larger fragments, they are prevented by the breaker bar 44 from entering the milling / mixing space, so that the milling / mixing roller 20 can gradually work them off before they can crushed enter the mixing chamber 24. Fragments of the milled material, which bounce against the bar from below, break at the breaker bar 44, so that it likewise contributes to the comminution.
  • replaceable breaker bars 44 at the lower end of the roll flap 27 is that they can be quickly and easily replaced, wherein the protection of the roller flap 27 and the roller housing 28 is improved against wear.
  • Fig. 8 shows an embodiment in which the lower part 32 can be pivoted relative to the upper part 30 in order to adapt to current or permanent bumps.
  • pivotable base 32 is also applicable in cases where the milling track is aware of the existing floor or traffic area 14, e.g. deviating from the horizontal, should be oblique.
  • the position of the base 32 relative to the top 30 can be adjusted with piston-cylinder units 40.
  • the piston-cylinder units 40 can make both the pivoting of the lower part 32 relative to the upper part 30, as well as the telescopic linear / arcuate adjustment.
  • the piston-cylinder units 40 can also be used to press the lower part 32 with a predetermined contact pressure against the ground or the traffic surface 14.
  • Fig. 9 shows a projecting in the direction of the milling / mixing roller 20 crusher bar 44 which projects from the lower part 32 and has a toothed outer contour.
  • the outer contour is adapted to the line spacing of the tools 22 of the milling / mixing roller 20.
  • the crusher bar 44 is flexibly adjustable due to the controllable roller flap 27, so that the engagement of the breaker bar 44 in the gaps between the tools 22 is adjustable in order to influence the grading curve in this way.
  • the breaker bar 44 may also have other and in particular simpler forms, as in Fig. 7 shown, and does not have the in Fig. 9 have apparent toothed outer contour.
  • Fig. 10 shows a further embodiment of the lower part, which is divided into a plurality of sub-elements 33.
  • Each sub-element 33 is coupled with a piston-cylinder unit 40 with the upper part 30 of the roller flap 27, so that each sub-element 33 can be adjusted individually.
  • Fig. 11 shows a piston-cylinder units 48 which are attached on the one hand to the roll flap 27 and the other on a mounting 52 of the machine frame 4. With the piston-cylinder units 48, the roll flap 27 can be pivoted, while with the piston-cylinder units 40, the lower part 32 relative to the upper part 30 can be adjusted.
  • Fig. 11 further shows an embodiment in which 32 runner-like sliding shoes 46 are mounted on the underside of the lower part. These can also be pressed against the floor surface 3 or a traffic area. Material lying in front of the roller housing 27 can pass through the free spaces between the sliding shoes 46 into the roller housing 27, even if it is guided over the floor surface 3 as a hold-down device.
