Description

The present invention relates to a sweeping device for a vehicle.

Sweeping devices that can be attached to vehicles are known per se. For example, the DE 10 2011 051 223 A1 a sweeping device for a vehicle, comprising a receiving device for receiving the sweeping device by means of the vehicle, a sweeping broom and a clearing blade arranged in the longitudinal direction in front of the sweeping broom. In this sweeping device, the clearing blade and the broom are firmly connected to one another and can be pivoted together about different axes.

It is desirable to be able to use sweeping devices flexibly for various sweeping or clearing work. Neither the sweeping devices nor a surface to be cleaned should be subjected to excessive stress or wear.

It is the object of the present invention to provide a sweeping device which can be adapted particularly easily and flexibly to different sweeping conditions.

This object is achieved by a sweeping device for a vehicle with the features of the independent claims.

Further possible configurations of the invention are given in particular in the subclaims.

The sweeping device according to the invention for a vehicle comprises a receiving device for receiving the sweeping device by means of the vehicle and a broom. Said receiving device can comprise one or more mechanical interfaces so that the sweeping device can be attached to one type of vehicle or also to different types of vehicle. For example, the receiving device can be designed to attach the sweeping device to a telescopic loader, a front loader or the like.

On the side of the broom, respective height-adjustable skids are arranged, which limit a maximum possible compression of the respective bristles of the broom in the vertical direction of the sweeping device. Depending on the nature of the ground to be swept and / or depending on the nature of the bristles of the sweeping broom, the height-adjustable runners can be used to determine how much the respective bristles of the sweeping broom can be compressed in the vertical direction of the sweeping device. For example, it is possible that the height-adjustable runners are used to compensate for wear on the bristles of the sweeping broom. If the bristles are still new, they are relatively long, for example, whereas the bristles can become shorter due to constant wear. The height-adjustable runners ensure that the bristles are always pressed onto the ground with sufficient pressure and are in contact with it, so that a good sweeping effect can be achieved. On the underside of the height-adjustable skids, for example, slide strips, for example made of polyurethane or the like, can also be arranged. As a result, a floor to be cleared or swept can be protected. Furthermore, the runners themselves do not wear out, but only the sliding strips, which can be replaced if necessary. The skids can, for example, be fixed steplessly or locked in individual steps in different positions. The latter can be implemented, for example, in that the skids are guided in corresponding receptacles with the aid of perforated rods or the like, which in turn have a hole. The skids can then be fixed in a respective position using a bolt.

As an alternative or in addition to the height-adjustable skids, the sweeping device according to the invention comprises an attachment, which can be mounted in the longitudinal direction of the sweeping device in front of the sweeping brush, for clearing a subsurface, which when mounted is at least indirectly supported on the sweeping brush by means of a holding device and can be moved relative to the sweeping brush by means of the holding device. The attachment can thus be dismantled from the rest of the sweeping device, as can the holding device. Several different types or variants of add-on parts that can be attached in front of the broom can also belong to the sweeping device. The holding device can be designed to accommodate all different types or variants of the add-on parts and to mount them at least indirectly on the broom so as to be movable relative to the latter. If the attachment is not required, the broom can be used without the attachment, for example because it is on one to be swept There are no particularly large pieces of dirt or large amounts of snow on the ground. If, on the other hand, there are large pieces of dirt, scrap pieces, snow masses or the like on the surface to be cleaned, the attachment can be mounted in front of the broom.

In the assembled state, the attachment is thus arranged in the longitudinal direction of the sweeping device in front of the broom. This means that in relation to the intended sweeping direction of the sweeping brush, the attachment is arranged in front of the sweeping brush. If the sweeping device is moved by means of the vehicle over a surface to be swept or cleaned with the add-on part installed, the add-on part first comes into contact with dirt, snow or the like to be removed. By means of the attachment, large or bulky elements in particular can be cleared away before the broom ensures that the surface to be swept is cleaned as thoroughly as possible. In this way, a particularly good sweeping and clearing effect is achieved by means of the sweeping device just by driving over a surface once.

Because the attachment is at least indirectly supported on the broom by means of the holding device and can be moved or adjusted relative to the broom by means of the holding device, the sweeping device can be particularly easily and flexibly adapted to a wide variety of sweeping conditions. The attachment can therefore be adjusted independently of the position of the broom relative to it. For example, the attachment can be mounted on the top of the broom by means of the holding device, directly or indirectly. Of course, this does not mean that the attachment is attached to the respective bristles of the sweeping broom. The attachment can, for example, be mounted on a housing of the sweeping broom - directly or indirectly - through the intermediary of the holding device. Said housing can serve to accommodate the bristles of the sweeping broom. The holding device has suitable means in order to be able to adjust the attachment relative to the broom. Adjustment is to be understood in particular to mean that the attachment part can be moved translationally and / or rotationally relative to the broom.

The broom can therefore always be arranged in such a way that a particularly good sweeping effect is achieved. Depending on the sweeping or clearing task and boundary conditions, the attachment can be adjusted relative to the broom in order to achieve a particularly good clearing effect without damaging the attachment and a substrate to be swept and cleared.

The attachment can be a dozer blade or a shovel. Depending on what kind of subsoil is to be cleared or cleaned, it may be advisable to mount a clearing blade or a shovel. If, for example, snow is to be cleared by means of the sweeping device, it may be advisable to provide a clearing blade as the attachment. By tilting the clearing blade, snow to be cleared can be cleared sideways to the right or to the left, after which any remaining snow can be swept away from the ground by means of the sweeping broom. If, on the other hand, dirt to be cleared or even snow, for example, can be transported away or removed as quickly as possible without the snow or dirt simply being cleared away to the side, it may be advisable to use a shovel as the attachment. By means of the shovel it is possible to pick up materials to be cleared and, if necessary, immediately clear them away by lifting the filled shovel so that materials picked up by means of the shovel can be removed.

A possible embodiment of the invention provides that the attachment can be pivoted about a vertical axis relative to the broom by means of the holding device. The attachment can thus be adjusted obliquely to the longitudinal direction of the sweeping device and thus also obliquely to the intended sweeping direction of the sweeping broom by means of the holding device. For example, it is possible to pivot the attachment in such a way that coarse dirt and / or snow can be pushed away laterally to the right or left by means of the sweeping device, for example during a combined sweeping and clearing process. The orientation of the sweeping broom can remain independent of the position of the attachment so that an optimal sweeping effect is achieved. A transverse direction of the sweeping broom can, for example, remain aligned transversely to a direction of movement or travel direction of the sweeping device, while the attachment, on the other hand, is positioned at an angle to the travel direction or sweeping direction of the sweeping broom, for example an acute angle between a front of the attachment and a forward travel and thus sweeping direction includes. For example, several rows can be covered with a vehicle to which the sweeping device is attached, with the attachment, for example, always clearing away snow laterally to the left or right when driving on the respective rows. Any remaining snow on the ground behind the attachment is then removed using the sweeping broom. This can of course also be used for all other types of dirt or similar to be removed. so done.

Another possible embodiment of the invention provides that, for pivoting the attachment around the vertical axis, the holding device has two telescopic rods which can be extended independently of one another, which are arranged at least indirectly on the broom in a left and right area in relation to the transverse direction of the sweeping device and at least indirectly on the rear Attachment are mounted with a degree of freedom of rotation around the vertical direction. By extending or retracting the respective telescopic rods to different extents, the add-on part can easily be pivoted or rotated about the vertical axis of the holding device. Because the telescopic rods are at least indirectly supported on the attachment with a degree of freedom of rotation around the vertical direction, the attachment can easily pivot relative to the respective telescopic rods when the telescopic rods are extended and retracted. When the telescopic rods are extended and retracted, relatively small forces act on the sweeping device, which result from the pivoting of the attachment.

According to a further possible embodiment of the invention, it is provided that the telescopic rods have a first telescopic element attached at least indirectly to the broom and a second telescopic element which can be extended from this and which can each be fixed to the respective first telescopic element in differently extended positions. The second telescopic elements can therefore be moved out of and into the respective first telescopic elements to different degrees. For example, the second telescopic elements can have a plurality of holes arranged one behind the other in relation to the longitudinal direction of these telescopic elements, wherein the second telescopic elements in turn can each have a hole. By inserting a respective bolt through the one hole of the first telescopic elements and through one of the respective holes of the second telescopic elements, the latter can be fixed very easily in a respective extended position. However, it is just as possible for the second telescopic elements to be infinitely adjustable, that is to say can be fixed in any extended and retracted positions on the first telescopic element. For this purpose, respective clamping devices can be provided on the telescopic rods.

In a further possible embodiment of the invention, it is provided that the attachment part can be adjusted in height relative to the broom by means of the holding device. If the ground to be cleared is very uneven, for example, it is possible to remove the attachment using the Lift the holding device a little so that neither the subsurface nor the attachment are damaged by the unevenness of the subsurface.

According to a further possible embodiment of the invention, it is provided that, for height adjustment of the attachment, the holding device is mounted on the broom so that it can pivot about a transverse axis of the sweeping device, at least indirectly. If you want to lift the attachment a little, for example, the holding device simply has to be pivoted accordingly about the transverse axis of the sweeping device. This results in a particularly simple and space-saving possibility of adjusting the height of the attachment relative to the broom.

Another possible embodiment of the invention provides that the holding device rests at least indirectly in a lower pivot position on the broom and can be pivoted freely upwards from there so that the attachment can move upwards following unevenness in the floor. If the sweeping device drives over unevenness in the floor, the attachment can simply move upwards following unevenness in the floor due to this described storage. This ensures that neither the attachment nor the relevant subsurface are damaged. In other words, a kind of pendular mounting of the attachment on the broom is provided. In the lower pivot position, the broom rests at least indirectly on the broom with the intermediary of the holding device, whereby the lower pivot position is defined. The lowest possible arrangement of the attachment is therefore defined by the lower pivot position in which the holding device rests at least indirectly, in particular on the top side, on the broom. Thus little or no great forces act on the pivotable mounting of the holding device. Starting from this lowest possible position, the attachment can easily move upwards at any time, e.g. a bump or similar is run over. Because due to the described pivotable mounting of the holding device about the transverse axis, the holding device is automatically pivoted about the transverse axis by means of the attachment when crossing uneven ground by means of the attachment. As a result, the attachment automatically moves upwards following the unevenness in question.

In a further possible embodiment of the invention it is provided that the lower pivot position of the holding device and thus an angle of incidence between the holding device and the broom can be varied by means of at least one screw drive. In the holding device can, for example, be embedded in weld nuts. Screws serving as screw drives, for example, can be screwed into these weld nuts. Depending on how far these screws are screwed in, the lower pivot position changes, since the holding device is moved away from the broom or raised under the action of the screws, in that the holding device is pivoted accordingly about the transverse axis. Depending on what is desired for a position in relation to the vertical direction with regard to the attachment, the lower pivot position can be changed very easily. By means of the at least one screw drive, it is possible to set the lower pivot position of the holding device and thus a distance between a lower edge of the attachment and a substrate without a particularly large force.

In addition, a further possible embodiment of the invention provides that the sweeping device has a radio transmitter with an integrated inclination sensor, which is designed to detect an inclination of the sweeping broom, in particular about its transverse axis, and to send data characterizing the inclination to a receiver, in particular a smartphone to send. A driver of the vehicle, by means of which the sweeping device is moved, can therefore easily see on his smartphone, for example, whether the inclination of the sweeping broom, in particular about its transverse axis, is correctly set. Correct can in particular mean that all the bristles of the sweeping broom are arranged at the same height and thus evenly touch the surface to be cleaned or swept. This can ensure that the bristles of the broom are not worn differently. If the vehicle is, for example, a tractor with a front loader, the driver can operate the front loader accordingly until the radio transmitter indicates that the inclination of the sweeping broom is correctly or optimally set. The driver of the vehicle in question does not even have to leave his vehicle in order to check the correct setting of the inclination of the sweeping brush.

According to a further possible embodiment of the invention, it is provided that if the add-on part is a shovel, the shovel is mounted on the broom such that it can pivot about an axis running in the transverse direction. In particular when the sweeping device is mounted on a vehicle by means of which the shovel itself cannot be tilted, it is advantageous if the shovel is mounted on the broom such that it can pivot about said axis running in the transverse direction. In this context it can also be provided that the shovel can be pivoted about the axis by means of an adjustment unit. The adjustment unit can have at least one actuator which is designed to pivot the blade hydraulically, pneumatically, electrically or magnetically about the axis. For example, the actuator can be a hydraulic cylinder or a pneumatic cylinder. However, other types of actuators are also possible. If the shovel has been filled with material to be removed and lifted, it is possible, for example, to pivot the shovel downward about the axis running in the transverse direction in order to empty the shovel very easily. The sweeping device can, for example, have an interface for a vehicle, so that it is possible from within the vehicle, for example by activating the at least one actuator, to pivot the shovel very easily when required. In principle, the shovel can also be pivoted manually.

Another possible embodiment of the invention provides that the sweeping device has a locking device by means of which a pivoting movement of the shovel about the axis can be blocked. The locking device can, for example, comprise a bolt or also a screw, by means of which the pivoting movement of the blade about the axis can be blocked. This is particularly helpful when the sweeping device is attached to a vehicle which itself can tilt the entire sweeping device and thus also the shovel, for example when the sweeping device is attached to a front loader.

In a further possible embodiment of the invention it is provided that at least one further height-adjustable skid is arranged in a front area and / or on a rear area on the broom, which limits a maximum possible compression of the respective bristles of the broom in the vertical direction of the sweeping device. A plurality of the further skids can also be arranged on the front and / or on the rear. In particular, it can be provided that at least one of the further skids is arranged on the front and rear. Together with the laterally attached skids, it is particularly reliable to prevent the bristles of the broom from being compressed. The other skids can e.g. be clamped by means of screws and continuously adjustable in height.

Further possible configurations and features of the invention are given in the following description of the figures. The features and feature combinations mentioned above in the description as well as those below in the description of the figures and / or in Features and combinations of features shown alone in the figures can be used not only in the respectively specified combination, but also in other combinations or alone, without departing from the scope of the invention.

A sweeping device 10 for a vehicle not shown here is shown in a perspective view obliquely from the front in FIG Fig. 1 shown. The sweeping device 10 comprises a receiving device 12 for receiving the sweeping device 10 by means of the vehicle. The vehicle can be, for example, a telescopic loader, front loader or the like. In addition, the sweeping device 10 comprises a sweeping broom 14 and an add-on part, arranged in the longitudinal direction x of the sweeping device 10 in front of the sweeping broom 14, for clearing a subsurface in the form of a clearing blade 16. For the sake of clarity, the reference symbol for the holding device 18 has been entered twice here. The holding device 18 comprises several elements, which are described in more detail below.

By means of the holding device 18, the clearing blade 16 can be adjusted relative to the broom 14. On the one hand, the clearing blade 16 can be pivoted relative to the broom 14 by means of the holding device 18 about a vertical axis running parallel to the vertical direction z. In addition, the clearing blade 16 can be adjusted in height relative to the broom 14 by means of the holding device 18. To adjust the height of the clearing blade 16, the holding device 18 is mounted on the broom 14, more precisely on the top of the housing 20 of the broom 14, so that it can be pivoted about a transverse axis 22 of the sweeping device 10 running parallel to the transverse direction y.

On opposite sides of the broom 14, respective height-adjustable skids 24 are arranged, which limit a maximum possible compression of the respective bristles 26 of the broom 14 in the vertical direction z of the sweeping device 10. By retracting or extending the runners 24, the distance between the housing 20 of the sweeping broom 14 and a substrate can be adjusted. In other words, the runners 24 determine how far the sweeping device 10 can be lowered towards the ground. Even if the sweeping device 10 is pressed down firmly with a front loader, for example, the height-adjustable skids 24 ultimately limit how firmly the respective bristles 26 of the sweeping broom 14 are pressed against the ground and compressed in the process.

Furthermore, the sweeping device 10 comprises a radio transmitter 28 with an integrated inclination sensor, which is designed to detect an inclination of the sweeping broom 14, in particular about its axis running parallel to the transverse direction y, and to transmit data characterizing the inclination to a receiver, for example to a smartphone To send the driver of the vehicle by means of which the sweeping device 10 is moved. It is thus very easily possible for the driver, without leaving the vehicle in question, to check or to recognize whether the bristles 26 of the sweeping broom 14 are aligned as optimally as possible with the ground to be swept. Optimal means in particular that the inclination of the sweeping broom 14 is tilted about the axis running parallel to the transverse direction y in such a way that the bristles 26 are all at least substantially the same distance from the ground or all of the bristles 26 touch the ground evenly.

If this is not the case, the driver can change the inclination of the sweeping broom 14, for example by operating the front loader of the vehicle accordingly the radio transmitter 28 with the integrated inclination sensor shows the driver, for example, in turn on his smartphone, for example by means of a suitable app, whether the best possible arrangement or inclination of the sweeping broom 14 has been set. The radio transmitter can, for example, have a Bluetooth module in order to wirelessly transmit the data characterizing the inclination of the sweeping broom 14 to the driver's smartphone via Bluetooth. Other wireless transmission technologies are of course also possible, such as WLAN or the cellular network.

In Fig. 2 the sweeping device 10 is shown in a plan view from above. To pivot the clearing blade 16 about the vertical axis, the holding device 18, not shown in detail here, has two telescopic rods 30 which can be extended independently of one another and which, based on the transverse direction y of the sweeping device 10, are at least indirectly on the broom 14 in a left and right area, here specifically on the top of the housing 20 of the broom 14 are arranged. In addition, the telescopic rods 30 are each mounted at the rear at least indirectly on the clearing blade 16 with a degree of freedom of rotation about the vertical direction z. As can be seen here, the clearing blade 16 can be pivoted relative to the sweeping brush 14 by extending or retracting the telescopic rods 30, so that an angle α between a front side 32 of the sweeping broom 14 and a rear side 34 of the clearing blade 16 can be varied.

The telescopic rods 30 each have a first telescopic element 36 fastened at least indirectly to the broom 14 and a second telescopic element 38 which can be extended therefrom and which can each be fixed to the first telescopic element 36 in positions that are extended to different extents. The first telescopic elements 36 each have a hole 42, the second telescopic elements 38 having a plurality of holes 40 arranged one behind the other. As soon as one of the holes 40 has been brought into overlap with the relevant hole 42, a bolt can, for example, be inserted through the relevant holes 40, 42 in order to determine the respective position of the second telescopic elements 38 and thus the angle a according to which the clearing blade 16 is relatively was pivoted to the broom 14 to fix. Stepless adjustability and, above all, fixability of the second telescopic elements 38 on the first telescopic elements 36 is of course also possible. This can be done, for example, using a suitable clamping device.

In the present illustration, said transverse axis 22 can again be clearly seen, about which the holding device 18, not designated in any more detail here, which comprises the telescopic rods 30, can be pivoted in order to adjust the height of the clearing blade 16. In the case shown here, the two first telescopic elements 36, which are attached to the holding device 18 (see Fig. 1 ) belong, pivotable about the transverse axis 22 on the broom 14, more precisely on the housing 20 of the broom 14 on the upper side. In all of the figures, the holding device 18, thus also the first telescopic elements 36, is shown in its lower pivot position. In this lower pivoted position of the holding device 18, it rests with its first telescopic elements 36 on the housing 20 of the sweeping broom 14. Starting from this lower pivot position, the holding device 18 and thus also the clearing blade 16 can be freely pivoted upwards, so that the clearing blade 16 can evade upwardly following unevenness in the ground. If the sweeping device 10 drives over an unevenness in the ground, the clearing blade 16 can easily move upwards when driving over the unevenness of the ground due to the pivotable mounting of the holding device 18 about the transverse axis 22. Damage to the clearing blade 16 and also damage to the relevant subsurface can thereby be avoided.

The lower pivot position of the holding device 18 and thus an angle of incidence between the holding device 18 and the broom 14 can be configured to be variable by means of at least one screw drive. In the case shown here, respective weld nuts 44 are attached in the area of through openings (not designated in more detail) of the first telescopic elements 36. A respective screw, for example, can be screwed in through these weld nuts 44. Depending on how far or how deep the screw is screwed in, the first telescopic elements 36 are pressed upwards by the housing 20 of the sweeping broom 14 through the intermediary of the respective screws. The first telescopic elements 36 are designed, for example, as hollow profiles or also as U-shaped profiles. In the latter case, the first telescopic elements 36 are then downward - that is, in the direction of the housing 20 - open. Said screws can, for example, be supported directly on the housing 20 and, depending on the screw-in depth, can pivot the telescopic rods 30 together with the clearing blade 16 upwards or downwards. Because of the pivotable mounting about the transverse axis 22, an inclined position of the entire holding device 18 and thus of the clearing blade 16 is influenced. In this way, the lower pivoting position of the holding device 18 and thus the lowest possible position of the clearing blade 16 can be set very easily.

In Fig. 3 the sweeping device 10 is shown in a perspective view obliquely from behind. In the present illustration, one can clearly see the receiving device 12, which serves to receive the sweeping device 10 by means of a vehicle, for example by means of a front loader, a telescopic loader, a forklift or the like. In the case shown, the receiving device 12 has several different interfaces at which a respective vehicle can grasp or pick up the sweeping device 10.

On the one hand, the receiving device 12 has a plate 46 which, for example, can serve as a screw-on interface for a front loader. For example, if a shovel has been removed from the front loader, the front loader can be screwed to the plate 46 with its corresponding interface. In addition, the receiving device 12 has receiving areas 48 into which, for example, the tines of a telescopic loader or a forklift truck can be inserted. In the present case, the receiving areas 48 are provided by hollow profiles, not designated in any more detail, which are fastened on the upper side of the housing 20 of the sweeping broom 14. The receiving device 12 also has two receiving areas 50 to the left and right of the plate 46, into which, for example, a shovel of a wheel loader can be moved. These receiving areas 50 are delimited by two profiles 52, 54, with respective weld nuts 56 being fastened in the upper of the two profiles 54. For example, screws can be screwed in through these weld nuts 56 in order to fix a wheel loader or front loader shovel inserted into the receiving area 50. In a departure from the present illustration, the receiving device 12 can, for example, also have a type of frame which has the shape of bales, so that a bale gripper of a vehicle can grip the frame in order to receive the sweeping device 10.

To the left and right on the respective unspecified sides of the sweeping broom 14 or on its housing 20, respective dipstick rods 58 are arranged. These make it easier for a driver of a vehicle in question, by means of which the sweeping device 10 is picked up and moved, to estimate where the sweeping device 10 ends laterally. If, for example, an excavator is used to pick up the sweeping device 10, an excavator shovel could for example partially or completely block the driver's view of the sweeping device 10, apart from the dipstick 58 See the dipstick 58 so that he can easily estimate where the sweeping device 10 or at least the broom 14 ends laterally.

In Fig. 4 the sweeping device 10 is shown in a side view, the clearing blade 16 not being mounted on the rest of the sweeping device 10. In the present illustration, one of the two height-adjustable skids 24 can be clearly seen. The runners 24 are fixed laterally on the housing 20 of the sweeping broom 14 by means of hollow profiles 60. On the respective longitudinal sides of the housing 20, receptacles 62 are arranged, which serve to receive and fix the hollow profiles 60 in different positions.

In the present setting of the height-adjustable skids 24, they are extended or retracted to such an extent that, in the unloaded state, the bristles 26 touch the ground and the skids 24 do not. If the sweeping device 10 is pushed downwards in the vertical direction z, the skids 24 come into contact with the ground with their underside (not shown) and thereby limit a further lowering of the sweeping device 10 and thus a further compression of the bristles 26 of the sweeping broom 14 that the bristles 26 are compressed or crushed too much. At the same time, by appropriately setting the skids 24, it can be ensured that when the appropriate pressure is exerted on the sweeping device 10 downwards, the bristles 26 exert sufficient contact pressure on the ground so that a good sweeping effect or cleaning effect of the ground can be achieved.

In Fig. 5 the sweeping device 10 is shown in a front view, inter alia, the clearing blade 16 is not mounted. As can be seen, the bristles 26 of the sweeping broom 14 extend at least substantially over the entire width of the sweeping broom 14. The individual bristles 26 can, for example, be combined in bristle packs or bristle modules that are not shown in detail and are located on the underside or inside of the housing 20 of the sweeping broom 14 be attached. In addition, the arrangement of the runners 24, which are attached to the left and right sides of the broom 14, can be seen again here. On the underside of the skids 24, unspecified slide strips can be attached, which can be made of polyurethane, for example. As a result, a surface to be swept or cleaned can be spared, at the same time it can be prevented that the skids 24 are worn out. As soon as the wear strips are worn, they can be easily replaced.

The bristles 26 can also be arranged one behind the other in different rows. The clearing blade 16, not shown here, can be provided on the underside, for example, with a scraping edge made of highly wear-resistant steel or also made of polyurethane. In addition, it is also possible for the sweeping device 10 to have different variants of mountable clearing blades 16, which can differ, for example, with regard to their size or also with regard to their material properties.

In Fig. 6 is the in Fig. 5 marked section A shown in a detailed view. In the present case, one of the two skids 24 can be seen, which is fixed in a height-adjustable manner on the receptacle 62 through the intermediary of the hollow profile 60, which in turn is fastened to the housing 20 of the sweeping broom 14, which is not described in detail here. The receptacle 62 has a through opening or a hole 64, the hollow profile 60 in turn having a plurality of through openings or holes 66 arranged one behind the other in a row or one above the other. As soon as one of the holes 66 has been brought into overlap with the hole 64, for example a bolt can be inserted through the relevant holes 64, 66 in order to fix the skid 24 at a certain height setting. A stepless fixability of the skids 24, for example by means of a suitable clamping device, can also be provided.

By means of the explained sweeping device 10, it is very easily possible to adapt, in particular, the position or arrangement of the clearing blade 16 relative to the sweeping broom 14 to the most varied of boundary conditions. By means of the sweeping device 10, it is possible to sweep and clean an underground in a very short time. In winter it is also possible, for example, to push away snow by means of the inclined clearing blade 16 and at the same time to cleanly sweep away the remaining snow behind it by means of the sweeping broom 14.

Even with uneven surfaces, it is possible to clean the subsurface without damaging the surfaces in question and without damaging the clearing blade 16. Because the clearing blade 16 is pivoted about the transverse axis 22 through the intermediary of the holding device 18, the clearing blade 16 can simply move upwards following uneven ground if necessary. Since the bristles 26 of the sweeping broom 14 have a certain resilience, they can continue to be pressed onto the ground when driving over uneven ground, whereby - depending on the local nature of the ground - the height-adjustable runners 24 can ensure that the bristles 26 are not compressed too much and thereby affected. Said radio transmitter 28 with the integrated inclination sensor also facilitates the optimal setting or arrangement of the sweeping broom 14, so that the bristles 26 of the sweeping broom 14 are worn evenly and not unevenly.

In Fig. 7 a second embodiment of the sweeping device 10 is shown in a perspective view obliquely from the front, the attachment part for clearing the ground in this embodiment being a shovel 68 that is adjustable relative to the broom 14. The adjustment options in the case of the shovel 68 can be the same as in the embodiment with the clearing blade 16. The height-adjustable runners can also be provided in the second embodiment. In addition, the shovel 68 can, if necessary, also be tilted or pivoted about an axis running in the transverse direction y. The use of the shovel 68 can be particularly helpful when dirt or other materials are not only to be displaced by the sweeping device 10, but are also to be poured into a container or the like, for example. With the shovel 68, accumulated materials can be picked up very easily and disposed of directly.

The shovel 68 can be pivoted about said axis by means of an adjustment unit, which runs in the transverse direction y. In the case specifically shown here, the adjusting unit (not shown in more detail) comprises two hydraulic cylinders 70 serving as actuators, by means of which the blade 68 can be pivoted about the pivot axis running in the transverse direction y if necessary.

In Fig. 8 the second embodiment of the sweeping device 10 is shown in a perspective rear view. In the present case, one can clearly see that the hydraulic cylinders 70 are attached to the top of the broom 14 and to the rear of the shovel 68. The attachment or mounting of the hydraulic cylinders 70 is articulated so that the aforementioned tilting movement or pivoting movement of the shovel 68 can be carried out without any problems.

In Fig. 9 is the in Fig. 8 marked area B shown enlarged. In the present case, one of the two hydraulic cylinders 70 can again be clearly seen, which can tilt or pivot the shovel 68 by retracting or extending it.

In Fig. 10 is the in Fig. 8 marked area C shown enlarged. In the present case, the already mentioned axis 72 has now been provided with a reference number which runs in the transverse direction y, around which the blade 68 can be tilted or pivoted. In the present case, a locking device 74 can be seen, by means of which a pivoting movement of the blade 68 about the axis 72 can be blocked. In the case shown here, the locking device 74 is a nut which, for example, can be screwed onto a bolt or also onto a screw. The pivoting movement or the tilting movement of the blade 68 about the axis 72 can be blocked by tightening the nut. This can be helpful if the entire sweeping device 10 is attached to a vehicle which can tilt the sweeping device 10 and thus also the shovel 68. For example, the vehicle can be a front loader to which the sweeping device 10 is attached. In that case it is not necessary to tilt the shovel 68 by actuating the hydraulic cylinders 70 accordingly.

The sweeping device 10 can also include different variants of the clearing blade 16 and the shovel 68, all of which can be compatible with the rest of the sweeping device 10, i.e. in particular can be stored and fixed on the top of the broom 14 in the manner described.

In Fig. 11 a third embodiment of the sweeping device 10 is shown in a perspective rear view. The third embodiment differs from the previous embodiments in that the sweeping device 10 has further height-adjustable skids 76 in a front and / or rear area. Two of the further skids 76 can be seen here, which are arranged on the rear of the housing 20 of the sweeping broom 10.

In Fig. 12 the third embodiment of the sweeping device 10 is shown in a side view. In the present case, it can be seen that at least one further height-adjustable skid 76 is arranged on the front of the housing 20 of the sweeping device 10, which is not identified here. For example, two of these further skids 76 can be provided on the front and rear. The skids 76 can be clamped by means of respective screws 78, which enables the skids 76 to be adjusted continuously. A respectively desired height can thus be easily adapted and the wear of the sweeping broom 14, more precisely the bristles 26 of the sweeping broom 14, can be reduced. Alternatively or in addition to the screws 78 other adjustment and / or fastening means can also be provided in order to adjust the height of the skids 76. In other words, the runners 78 can be adjusted relative to the broom 14 in the vertical direction z.

The runners 76 can for example be made of a bent spring steel. A part of the skids 76 resting on the floor can run at least substantially parallel to the longitudinal direction x, wherein the part fixed by means of the respective screw 78 can run at least substantially parallel to the vertical direction z.
