Definitions
- the invention relates to a ground milling machine.
- a generic ground milling machine comprises a machine frame, connected to the machine frame driving devices, such as crawler tracks or wheels, a drive motor, typically a diesel engine, a control station, from which the operation of the Bodenfräsmaschine takes place, and a Bodenfräs observed comprising a milling drum and a surrounding milling drum box.
- the Fräswalzenkasten has transversely to the rotational axis of the milling drum arranged height-adjustable side shields, wherein an outer side plate is substantially flush with an outer side, in this case also referred to as zero side of the machine frame and an inner side plate is offset from an opposite outside in the direction of the machine longitudinal center, for example for connecting a drive gear for the milling drum.
- the inner side shield thus does not terminate flush with the outside of the ground milling machine opposite the null side.
- Such a generic ground milling machine is known for example from the patent publications DE 10 2012 021 379 A1.
- Ground milling machines are usually used for milling the soil background.
- Ground milling machines of the road milling machine type are used concretely, for example for milling road surfaces during road repair work.
- the milling drum is moved into the soil subsoil in a rotating manner over the soil substrate to be abraded and thereby mills the soil material at a desired milling depth.
- the milling drum is known to be arranged in a direction controlled by the ground surface to the milling drum box for a controlled material guide. This can be rigid with the machine frame or relatively movable to the machine frame. be attached to this machine frame.
- the milling drum box thus constitutes an enclosure for the milling drum which is open towards the ground, wherein it includes, inter alia, the side shields which are arranged opposite one another on both sides along the axis of rotation of the milling drum for adaptation to different milling depths.
- the side shields are adjustable relative to the milling drum in its height position, for example via hydraulic cylinders or similar type adjusted devices, or can be performed in a floating state on the ground.
- the basic structure and mode of operation of such side shields is specified, for example, in DE 10 2011 147 710 A1, to which reference is hereby made.
- ground milling machines A major challenge in the use of such ground milling machines is an exact guidance of the machine on the ground to be scoured ground.
- the driver of the ground milling machine orients itself on the outside or the zero side of the ground milling machine. This zero side is located where the milling drum terminates substantially flush with the machine frame. Specifically, the external side shield is present at this point.
- the driver of the ground milling machines can then mill, for example, along markings applied on the ground, for example color markings, curbs, etc.
- the object of the invention is therefore to provide a way to facilitate in a generic ground milling the leadership of Bodenfräsmaschine inside milling.
- the solution of the problem is achieved with a ground milling machine according to the independent claim.
- Preferred developments are specified in the dependent claims.
- the basic idea of Finding is that a sighting tube is present, such that from the helm from the inner side plate and / or in the working direction in front of the inner side plate located bottom portion is at least partially visible.
- the sighting slot thus passes through an interior of the ground milling machine.
- the formation of the Masch inenrah mens and the arrangement of the other machine components is thus such that the sight-forming release is obtained by the machine from the control station towards the inner side plate, on the control of the view of at least a portion of the inner side plate and / or lying in the working direction in front of the inner side plate floor area is possible.
- the viewing shaft is thus a viewing channel through which the driver can see on the inner side plate and / or lying in the working direction in front of the tip of the side plate floor area.
- the working direction designates the direction in which the ground milling machine moves during milling. This usually corresponds to the forward direction of the ground milling machine.
- the sighting shaft extends from the control station to a region arranged above the inner side plate and / or extends beyond the ground area located in front of the inner side plate in the working direction.
- the viewing shaft has a shaft entrance, a shaft area and a shaft exit in the direction of sight of a driver located on the control station.
- the shaft area thus designates the interior of the sighting shaft between the shaft entrance and the shaft exit.
- the sight shaft extends at least along a line of sight of the driver located in the usual operating position on the control station on the hitherto hidden in the prior art inner side plate or lying in front of this side plate floor area. This provides the driver with a possibility of enabling accurate maneuvering of the ground milling machine, in particular along an inner milling edge and / or an inner reference, also by means of the inner side plate.
- the sight shaft in the vertical direction downwards substantially rectilinear, in particular with respect to its central shaft axis.
- the central shaft axis designates a connecting line that connects the centers of the horizontal contours of the sighting shaft in different vertical heights. This means that both the side walls and seen in the direction of the front wall and rear wall of the sight tube are substantially vertical.
- the walls bounding the sighting not necessarily have to be flat but can. Included are in particular Also, such embodiments in which, for example, seen in the horizontal plane, at least partially, a limitation of the sighting shaft is carried out by other machine elements.
- the sighting tube such that it extends obliquely in the vertical direction downwards and in the working direction forward, in particular with respect to its central shaft axis.
- Such an arrangement is particularly advantageous and useful if the view is to be made possible from the helm on a portion of the inner side plate, which takes place in the working direction before the usual operating position of the driver located in the control.
- the sighting slot is designed such that, for example, the front lying in the direction of the tip region of the side plate from the helm is visible.
- the sighting shaft extends in the working direction of the ground milling machine over the length, and in particular over the entire length, of the side shield. This allows the driver of the ground milling machine to observe the position of the inner side plate to the ground surface particularly well.
- the sighting tube is further dimensioned such that the view of a lying in the direction of the front edge of the inner side plate ground area from the control station is possible.
- the specific dimensioning of the sight slot can be made dependent in principle on the currently existing structural conditions on the ground milling machine.
- the sighting shaft is relatively narrow and formed in the horizontal direction with its longitudinal axis extending in the working direction.
- the ratio of the horizontal extent of the sighting shaft transversely to the working direction to the horizontal extent of the sighting shaft in the working direction is in the range from 1: 4 to 1:15, in particular in the range from 1: 5 to 1:10.
- the extent of the sighting channel transverse to the working direction and the extension of the sighting hole in the working direction are measured in a virtual horizontal reference plane.
- the respective average extent so that it does not depend on a rectilinear course of the wall or a distance, which is constant over the respective extent, of the respectively opposite shaft walls.
- the sight slot is seen in a horizontal plane to all four sides, in particular of parts of the machine frame, surrounded.
- At least one transverse strut is present, which spans the sighting channel transversely to the longitudinal direction of the ground milling machine.
- a transverse strut thus designates a web-like connecting part which in particular connects the opposite longitudinal sides of the sighting shaft to one another.
- the cross struts are also preferably kept relatively narrow in relation to the total extent of the sighting shaft, so that the visual impairment of the view through the sighting shaft, which accompanies the cross struts, is negligible.
- the sight tube opens to the driver preferably in a viewing opening in the Fahrstandêt of the control station.
- the driving floor designates that part of the control station on which the driver normally stands in the control station.
- the sight slot has a protective cover.
- the protective cover it is possible to cover the viewing shaft at least partially, in particular in the area of the shaft entrance, and in this way, for example, to achieve diarrhea protection and / or protection against dust and noise.
- the protective cover may be a protective grid which covers the viewing shaft.
- the protective cover may comprise a transparent protective pane, in particular of a scratch-resistant plastic.
- the protective cover is flush with the operator's floor to reduce the risk of tripping.
- the protective cover it is also possible for the protective cover to comprise a flap which, between a covering position covering the sighting slot and a release position enabled the view through the viewing slot is adjustable.
- the driver thus has, for example, the choice as to whether he would prefer to have a closed driving floor or the visibility provided by the sight shaft according to the invention.
- a flap may be adjustable for example via a pivot joint or a sliding guide between the two said positions.
- the sight slot can basically be installed where optimum visibility is given to the inner side plate of the driver located on the control station.
- the viewing shaft is arranged in relation to the width of the ground milling machine in the middle third.
- the width of the ground milling machine is determined by the maximum distance between the two extending in the horizontal plane in the direction opposite outer sides of the ground milling machine.
- the control station comprises a driver's seat, so that the driver can take over the operation of the ground milling machine, at least optionally also from a sitting position during operation.
- the sighting chute is particularly preferably arranged in the working direction of the ground milling machine next to the driver's seat, so that the driver can lean out of a seat operating position to the inside of the machine during work operation and can look into the sighting chute. It is therefore particularly preferred if the viewing shaft in the horizontal plane between the operating point, in particular the driver's seat, and a control panel runs.
- the sight tube is dimensioned such that it releases the view from the control station to a lying in front of a front tip of the inner side plate floor area. The driver can then see through the viewing shaft not yet run over by the Bodenfräs annoying area and thus make the control of the machine more accurate.
- the sighting chute is seen transversely to the direction of work between a rise, especially in the back of the Bodenfräsmaschine, and a rear Abstreifer Unit.
- the scraper guide is used to adjust a scraper blade arranged in the working direction behind the milling drum at a height adjustment.
- the advantages of the invention are particularly apparent in a ground milling machine of the type Heckrotorfräse.
- Such tail rotor cutters are characterized in that the milling device is arranged in the rear region of the ground milling machine, in particular between the two rear driving devices. It is also ideal if the control station is located above the bottom milling device as viewed in the vertical direction. Then the dimensioning of the sight slot can be kept relatively small.
- a laterally outer frame recess is provided in addition to the sight tube over which a lying in the direction of the Bodenfräs coupled bottom area, in particular on the sides flush with the engine compartment final side shield, from the helm is visible.
- This recess which is open laterally toward the null side, can also be used to receive a driving device that can be adjusted between a swung-out position and a swivel-in position, as described, for example, in DE19631042A1.
- a lighting device available is, which is designed such that it illuminates the relevant areas of the inner side plate and / or existing in front of and / or next to the inner side plate floor area. This additionally illuminates this area below the machine, which considerably improves the visibility conditions for the driver.
- a lighting device may be, for example, an LED device.
