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 as a result, 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 in the mounted state 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, e.g. because there are no particularly large pieces of dirt or large amounts of snow on a surface to be swept. If, however, e.g. On the surface to be cleaned, large pieces of dirt, scrap pieces, masses of snow or the like, 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 closed by means of the vehicle with the add-on part installed If the surface to be swept or to be cleaned is moved, the attachment 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 ground 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, a vehicle to which the sweeping device is attached can be driven over several rows, whereby by means of the attachment e.g. Snow is always cleared away 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 and 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 extending and Retraction of the telescopic rods thus act on the sweeping device with relatively low forces, 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 subsurface to be cleared is very uneven, for example, it is possible to raise the attachment a little by means of the holding device so that neither the subsurface nor the attachment is 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. Weld nuts, for example, can be embedded in the holding device. 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 to detect and the inclination characterizing data to a receiver, in particular a smartphone. 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 broom.

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 about the axis hydraulically, pneumatically, electrically or magnetically. 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.

The features and feature combinations mentioned above in the description as well as the features and feature combinations shown below in the description of the figures and / or in the figures alone can be used not only in the respectively specified combination, but also in other combinations or alone, without the scope of the invention to leave.

A sweeping device 10 for a vehicle not shown here is a perspective view obliquely from the front in 1 shown. The sweeping device 10 comprises a receiving device 12 for holding the sweeping device 10 by means of the vehicle. The vehicle can be, for example, a telescopic loader, front loader or the like. It also includes the sweeping device 10 a broom 14th and one lengthways x the sweeping device 10 in front of the broom 14th arranged attachment for clearing a subsurface in the form of a clearing blade 16 . The dozer blade 16 is by means of a holding device 18th on the top of a housing 20th of the broom 14th stored. For the sake of clarity, the reference symbol for the holding device has been used here 18th entered twice. The holding device 18th comprises several elements, which are described in more detail below.

By means of the holding device 18th can the dozer blade 16 relative to the broom 14th adjusted. On the one hand, the dozer blade 16 by means of the holding device 18th around one parallel to the vertical direction z running vertical axis relative to the broom 14th be pivoted. In addition, the dozer blade 16 by means of the holding device 18th relative to the broom 14th can be adjusted in height. For adjusting the height of the dozer blade 16 is the holding device 18th around one parallel to the transverse direction y running transverse axis 22nd the sweeping device 10 can be swiveled on the broom 14th , more precisely at the top of the case 20th of the broom 14th stored.

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

The sweeping device also includes 10 a radio transmitter 28 with an integrated inclination sensor, which is designed to measure the inclination of the sweeping brush 14th , especially about its parallel to the transverse direction y To detect the running axis and to send the inclination characterizing data to a receiver, for example to a smartphone of a driver of the vehicle, by means of which the sweeping device 10 is moved. In this way, it is very easy for the driver to check or to recognize whether the bristles have been removed without leaving the vehicle in question 26th of the broom 14th are aligned as optimally as possible to the ground to be swept. Optimal means in particular that the incline of the sweeping broom 14th around the parallel to the transverse direction y extending axis is tilted so that the bristles 26th all have at least substantially the same distance from the ground or all bristles 26th touch the surface evenly.

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

In 2 is the sweeping device 10 shown in a plan view from above. For swiveling the clearing blade 16 The holding device (not shown here) points around the vertical axis 18th two independently extendable telescopic poles 30th on that based on the transverse direction y the sweeping device 10 in a left and right area at least indirectly on the broom 14th , here specifically on the top of the case 20th of the broom 14th , are arranged. In addition, the telescopic poles are 30th at least on the back indirectly on the dozer blade 16 with a degree of freedom of rotation around the vertical direction z stored. As you can see here, the dozer blade can 16 by extending or retracting the telescopic rods 30th relative to the broom 14th be pivoted so that an angle α between a front 32 of the broom 14th and a back 34 of the dozer blade 16 can be varied.

The telescopic poles 30th each have an at least indirectly on the broom 14th attached first telescopic element 36 and a second telescopic element that can be extended from this 38 on, which are each in differently extended positions on the first telescopic element 36 is fixable. The first telescopic elements 36 each have a hole 42 on, the second telescopic elements 38 several holes arranged one behind the other 40 exhibit. Once one of the holes 40 in overlap with the hole in question 42 has been brought, for example, a bolt through the holes concerned 40 , 42 are inserted through to the respective position of the second telescopic elements 38 and thus the angle a, according to which the blade 16 relative to the broom 14th was pivoted 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, the said transverse axis is again 22nd easy to see around which the holding device (not shown here) 18th holding the telescopic poles 30th includes, is pivotable to the clearing blade 16 adjustable in height. In the case shown here, the first two are telescopic elements 36 , which to the holding device 18th (please refer 1 ) belong to the transverse axis 22nd can be swiveled on the broom 14th , more precisely on the housing 20th of the broom 14th stored on top. The holding device is in all figures 18th , so they are also the first telescopic elements 36 , shown in their lower pivot position. In this lower pivot position of the holding device 18th lies this with its first telescopic elements 36 on the case 20th of the broom 14th on. The holding device is based on this lower pivot position 18th and thus also the dozer blade 16 can be freely swiveled upwards so that the clearing blade 16 Following uneven ground can move upwards. So is by means of the sweeping device 10 drive over a bump in the ground, the dozer blade 16 when driving over the uneven floor due to the pivoting mounting of the holding device 18th around the transverse axis 22nd simply move upwards. Damage to the blade 16 and damage to the relevant subsurface can also be avoided.

The lower pivot position of the holding device 18th and thus an angle of attack between the holding device 18th and the broom 14th can be designed to be variable by means of at least one screw drive. In the case shown here, there are respective weld nuts 44 in the area of unspecified through openings of the first telescopic elements 36 appropriate. Through these weld nuts 44 For example, a respective screw can be screwed in. Depending on how far or how deep the screw is screwed in, the first telescopic elements 36 with the mediation of the respective screws from the housing 20th of the broom 14th pushed up. The first telescopic elements 36 are designed, for example, as hollow profiles or as U-shaped profiles. In the latter case, the first are telescopic elements 36 then downwards - in the direction of the housing 20th - open. Said screws can be attached directly to the housing, for example 20th support and, depending on the screw-in depth, the telescopic rods 30th including the dozer blade 16 swivel up or down. Due to the pivoting mounting around the transverse axis 22nd This means that the entire holding device is inclined 18th and thus the dozer blade 16 influenced. In this way, the lower pivot position of the holding device can very easily 18th and thus the lowest possible position of the blade 16 can be set.

In 3 is the sweeping device 10 shown in a perspective view obliquely from behind. In the present illustration you can see the recording device 12 recognize which serves 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. The receiving facility 12 has in the present case shown several different interfaces at which a respective vehicle the sweeping device 10 can take or take up.

On the one hand, the receiving device 12 a plate 46 on, which can serve as a screw-on interface for a front loader, for example. If, for example, a shovel was removed from the front loader, the front loader can with its corresponding interface on the plate 46 be screwed on. In addition, the receiving device 12 Recording areas 48 in which, for example, the prongs of a telescopic handler or a forklift truck can be inserted. Here are the recording areas 48 provided by unspecified hollow profiles which are attached to the housing 20th of the broom 14th are attached at the top. The receiving facility 12 also includes left and right of the plate 46 two more recording areas 50 into which, for example, a shovel of a wheel loader moves can be. These shooting areas 50 are through two profiles 52 , 54 limited, being in the upper of the two profiles 54 respective weld nuts 56 are attached. Through these weld nuts 56 For example, screws can be screwed in to insert one into the receiving area 50 to fix inserted wheel loader or front loader shovel. In a departure from the present illustration, the recording device 12 for example, also have a type of scaffolding which has the shape of bales, so that a bale gripper of a vehicle can grip the frame around the sweeping device 10 record.

Left and right on the respective unspecified sides of the sweeping broom 14th or on its housing 20th are respective dipsticks 58 arranged. These make it easier for a driver of a vehicle in question to use the sweeping device 10 is picked up and moved to estimate where the sweeper is 10 ends laterally. For example, an excavator is used to clean the sweeper 10 take, for example, an excavator shovel could block the driver's view of the sweeping device 10 partially or completely obstruct, except for the dipstick 58 . So from a driver's cab he can see the dipstick 58 so that he can easily assess where the sweeping device is 10 or at least the broom 14th ends laterally.

In 4th is the sweeping device 10 shown in a side view, the snow blade 16 not on the rest of the sweeper 10 is mounted. In the present illustration, one of the two height-adjustable skids can be used 24 recognize well. The skids 24 are mediated by hollow profiles 60 on the side of the housing 20th of the broom 14th fixed. On the respective long sides of the housing 20th are recordings 62 arranged, which serve the hollow profiles 60 take up and fix in different positions.

In the present setting, the height-adjustable skids 24 are these extended or retracted so far that the bristles in the unloaded state 26th touch the ground and the skids 24 Not. Becomes the sweeper 10 in vertical direction z pushed down, the skids will get there at some point 24 with their underside (not shown) in contact with the ground and thereby limit further lowering of the sweeping device 10 and thus a further compression of the bristles 26th of the broom 14th . This can prevent the bristles 26th are compressed or crushed too much. At the same time, you can adjust the skids appropriately 24 ensure that when the appropriate pressure is exerted on the sweeping device 10 down the bristles 26th Apply enough pressure to the surface so that a good sweeping or cleaning effect of the surface can be achieved.

In 5 is the sweeping device 10 shown in a front view, including the dozer blade 16 is not mounted. As can be seen, the bristles extend 26th of the broom 14th at least essentially over the entire width of the sweeping broom 14th . The individual bristles 26th can, for example, be combined in bristle packs or bristle modules, which are not designated and shown, and are located on the underside or inside of the housing 20th of the broom 14th be attached. You can also see the arrangement of the skids here 24 recognize which left and right side of the broom 14th are attached. On the underside of the skids 24 unspecified sliding strips be attached, which can be made of polyurethane, for example. As a result, a surface to be swept or cleaned can be protected, at the same time it can be prevented that the skids 24 in itself to be worn out. As soon as the wear strips are worn, they can be easily replaced.

The bristles 26th can also be arranged in different rows one behind the other. The clearing blade, not shown here 16 can be provided on the underside, for example, with a scraping edge made of highly wear-resistant steel or also made of polyurethane. It is also possible that the sweeping device 10 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 6th is the in 5 marked cutout A. shown in a detailed view. Here is one of the two skids 24 to recognize which mediating the hollow profile 60 height adjustable on the mount 62 is fixed, which in turn on the housing 20th of the sweeping broom not specified here 14th is attached. The recording 62 has a through opening or a hole 64 on, the hollow profile 60 in turn, several through openings or holes arranged one behind the other in a row or one above the other 66 having. Once one of the holes 66 with the hole 64 has been brought into overlap, for example, a bolt through the holes concerned 64 , 66 be inserted to the skid 24 to fix in a certain height setting. Stepless fixability of the skids 24 , for example by a suitable clamping device, can also be provided.

By means of the explained sweeping device 10 it is quite easily possible, especially the position or arrangement of the clearing blade 16 relative to the broom 14th adapt to a wide variety of boundary conditions. Using the sweeping device 10 it is possible to sweep and clean a surface in a very short time. In winter, for example, it is also possible to use the sloping blade 16 Push the snow away and at the same time clean the remaining snow behind it with the sweeping broom 14th to go away.

Even with uneven surfaces, it is possible without damaging the surfaces concerned and without damaging the clearing blade 16 to clean the surface. Because because the blade 16 with the mediation of the holding device 18th oscillating around the transverse axis 22nd is stored, the dozer blade 16 if necessary, simply move upwards to follow uneven ground. Because the bristles 26th of the broom 14th have a certain resilience, they can still be pressed onto the ground when driving over uneven ground, whereby - depending on the local nature of the ground - the height-adjustable skids 24 can ensure that the bristles 26th not be compressed too much and thereby affected. The said radio transmitter 28 the integrated inclination sensor also makes it easier to optimally adjust or arrange the sweeping brush 14th so that the bristles 26th of the broom 14th worn evenly and not unevenly.

In 7th is a second embodiment of the sweeping device 10 shown in a perspective view obliquely from the front, the attachment for clearing the ground in this embodiment being a shovel 68 acts that are relative to the broom 14th is adjustable. The adjustment options for the shovel 68 can be the same as in the embodiment with the dozer blade 16 be. The height-adjustable runners can also be provided in the second embodiment. In addition, the shovel can 68 if necessary by one in the transverse direction y running axis can be tilted or pivoted. The use of the shovel 68 can be particularly helpful if dirt or other materials are not only from the sweeping device 10 should be moved, but should be filled, for example, in a container or the like. Using the shovel 68 collected materials can be easily picked up and disposed of directly.

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

In 8th is the second embodiment of the sweeping device 10 shown in a perspective rear view. In the present case you can clearly see that the hydraulic cylinders 70 on the top of the broom 14th and on the back of the shovel 68 are attached. The attachment or storage of the hydraulic cylinders 70 is articulated so that the said tilting movement or pivoting movement of the shovel can be carried out without any problems 68 can be executed.

In 9 is the in 8th marked area B. shown enlarged. In the present case one of the two hydraulic cylinders can be used again 70 recognize which by retracting or extending the bucket 68 can tilt or pivot.

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

To the sweeper 10 can also use different versions of the dozer blade 16 and the shovel 68 belong, which all with the rest of the sweeping device 10 can be compatible, so in particular on the top of the broom 14th can be stored and fixed in the manner described.
