Abstract

The snow clearing machine consists of a motor vehicle with a snow plough (18) mounted at the front. A cylindrical brush (15) is mounted horizontally underneath the chassis between the front and rear wheels. The brush (15) is made in two parts each of which can be swung about a vertical axis so that the two parts can lie either on a common axis transverse to the vehicle or on axes inclined to each other. The two parts of the brush are driven from a central shaft driven by a chain. USE/ADVANTAGE - The two-part brush can be adapted to suit uneven ground.

Description


  
 



   DESCRIPTION



   It is known to equip snow removal machines with sweeping brushes, which can optionally be combined with a blower. Such sweeping brushes are usually arranged on snow removal machines which are equipped with a snow plow on the front. The purpose of the sweeping brushes arranged behind the snow plow in the direction of travel and as a rule pivotable to both sides is to sweep the snow left over from the snow plow on the road to the side.



  As already mentioned, this turning-away effect can be supported by an additional blower, by means of which the snow left by the plow and whirled up by the sweeping brush is blown off to the side. This means that the desired clearing of the road by the snow removal machine takes place in such a way that the snow left by the plow is lifted from the surface by the sweeping brush and whirled up and then laterally removed by a blower.



  Such complete snow removal therefore presupposes that the snow that has not been carried away by the plow and is still lying on the road can be picked up by the sweeping brush. If, as is the case with all known arrangements, the sweeping brush is designed in one piece and the roadway is not completely flat (for example, it is cambered against the edge thereof), the sweeping brush cannot grasp the snow still lying on the roadway, so that a complete cleaning of the road from snow is not possible.



   The known brushes, which usually have a very large broaching width, have a continuous support body and consequently cannot or only insufficiently adapt to unevenness in the transverse profile.



   Furthermore, the brush drive in the known one-piece brushes takes place on an outer brush end. This also complicates the handling, for example the dismantling of the brush body for the replacement of the brush segments.



   The object of the present invention was based on the object of improving the adaptation of a sweeping brush to the roadway to be cleaned, for which purpose the means mentioned in the characterizing part of patent claim 1 are arranged. The fact that the two sweeping brush halves can be pivoted relative to one another enables the sweeping brush to also detect snow that lies on planes that are at an angle to one another.



   An example of an embodiment of the subject matter of the invention is shown in the drawing, namely:
1 to 3, a snow removal device in a side view, a plan view and a front view,
4 to 6 is a somewhat more detailed illustration of the snow removal device, in which the special arrangement of the mechanical all-wheel drive can be seen,
7 is a view of the front of the sweeping unit,
Fig. 8 is a side view of the sweeping unit with suspension points of the unit on the carrier vehicle, an outer holding arm of the sweeping brush and the height-adjustable air nozzle at the end of the air duct.



   In Fig. 9 the same side view is shown immediately in front of the center of the unit with the middle brush suspension and drive and the hydraulic lifting device.



   10 shows a top view of the illustration according to FIG. 9,
Fig. 11 is a front view of the sweeping unit with the air deflection when entering the air supply duct, with the torsion bar connection between the hydraulic lifting devices and with the vertically adjustable air supply nozzle with return spring.



   12 and 13 represent a side view and a plan view of the outer holding and lifting device of the sweeping brush, while in the
14 and 15 the sweeping unit is shown diagrammatically.



   In a 3-point suspension 21, which in turn is attached to the vehicle frame 3, a turntable 22 is arranged. On the underside of the slewing ring 22, the air supply duct 23 designed as a supporting structure is mounted.



  The air duct runs from the center of the unit to the left and right ends. At the end of the air duct, the air is fed from the radial fan 13 via a pipe through the rotating ring 22, the pipe bend 24 and the air nozzle 25 to the air duct 26 arranged in front of the brush 15/16. The height of the air nozzle 25 can be adjusted by means of guide rails 27 and return springs (gas pressure springs) 28 and can thus be moved into the area of the air duct 26 or via this duct. The entire adjustment and in particular the force of the return spring 28 is dimensioned such that the nozzle 25 is automatically brought into the lower working position when a corresponding amount of air is supplied by the resulting back pressure and, if the air supply is interrupted, into the upper rhe position by means of a return spring.



  An air flap 30 can be brought into a left end position shown in FIG. 11 or a right end position shown in FIG. 15 via a hydraulic cylinder 29 and thus the air supply from the turbine to the air nozzle 25 can be controlled on the left or right. By means of a hydraulic cylinder, not shown, which is articulated on the one hand on the turntable 22 and on the other hand on the vehicle frame 3, the air duct and the sweeping brush connected to it can be moved around the vertical pivot point of the turntable in a working position shown in FIGS. 2 and 5 left or right or be brought into any intermediate position.



   A closed chain drive 32 is arranged on the swivel bearing 31 below the air supply duct 23, in the middle of the unit, and the lifting and holding arms 34 are rotatably arranged on the outer swivel bearings 33.



   A brush core with brush elements 15 and 16 is rotatably connected on the one hand via the multi-spline profile 35 and on the other hand is freely rotatable in the bearing 36 on the multi-spline 35 with arched shape which projects on the left and right of the chain drive 32 and on the outer bearings 36.



  By means of two double-acting hydraulic cylinders 37 arranged on the side of the chain gear 32 and on the other side on supports on the air guide tube, and two double-acting hydraulic cylinders 37 arranged on the lifting and holding arms 34 on the one hand and once on the right at the end of the air guide tube 23 and on the other hand on supports of the air supply duct 23 the sweeping brush 15/16 is raised in the transport position or lowered into the lower working position and held with a constant contact pressure.



   Two the pivot bearings 31 and 33 connecting torsion bars 38 are arranged for stabilization or mutual support of the lifting devices provided on the pivot bearings 31 and 33, but are dimensioned such that the chain transmission 32, which serves as the middle lifting device, and the outer lifting and Holding arms 34 can stand independently of each other in a certain angular range and thus enable the brush halves 15 and 16 to be optimally adapted to the traffic area to be cleaned, even when there are major unevenness and transverse slopes or roof profiles.

  The above-mentioned constant ground pressure of the sweeping brush halves 15 and 16 is ensured by the hydraulic system (not shown), consisting of a hydraulic pump, pressure relief valve, control valves and the four hydraulic cylinders, and enables the brush to rest as regularly as possible at all times and thus optimal clearing with minimal wear and tear and allows significantly higher clearing speeds to. The fixed arrangement of the entire air duct, designed as a load-bearing element, including the brush cover 39, enables the remaining total mass to remain as low as possible and thereby also contributes to the stabilization and quiet behavior of the sweeping brush parts 15 and 16. The two-part assembly facilitates the assembly and disassembly of the brush halves and thus the replacement of the individual brush segments.

  The brush halves 15 and 16 can consist of brush segments in the form of disks or strips, of steel wire or plastic.



   While the working motor 8 is running, the pumps 10 and 11 pivot the radial fan 13 on the one hand and the sweeping brush halves 15 and 16 on the other hand in rotation.



   As already mentioned, depending on the position of the air guide flap 30, the air supplied by the radial fan 13 is directed to the left or right air nozzle 25. Under the back pressure of the supplied air, the nozzle 25 lowers against the resistance of the tension spring 28 into the working position or is raised to the rest position when the air supply is interrupted.



  (Incidentally, this movement can also be solved hydraulically by arranging a hydraulic cylinder instead of the tension spring 28 and connecting it in series with the hydraulic cylinder 29, for example. This would automatically lower or raise the corresponding air nozzle 25 on the left or right when the air flap 30 is changed.)
The snow or dirt thrown up by the brush halves 15 and 16 into the region of the air duct 26 is caught in the air duct 26 by the rapid air flow from the nozzle 25 and blown out to the left or right. Through this air brush arranged on the front, the snow or dirt is not whirled up freely, but is redirected in flight and blown out laterally even when the brush is slightly inclined or even when the brush is at a right angle to the direction of travel.

  The rubber protective flaps 40 and 41 limit the working area of the sweeper once at the front and once at the rear.



   The entire operation and monitoring of the working motor 8 and the implements (snow plow and sweeper) takes place electrically or electrohydraulically from an additional operating and monitoring console in the cab. The simple arrangement and the selected drive system with automatic transmission enable easy handling by the driver without another operator. The hydraulic drives of the radial turbine and the sweeping brushes are protected against overload by the pressure cut-off setting of the oscillating piston pumps.

 

   The mechanical attachment of the entire sweeper via the 3-point suspension 21 as well as the hydraulic connections for the brush drive and the actuation of the hydraulic cylinders is designed so that it can be attached and detached to the carrier vehicle in a relatively short time and easily. The entire sweeper is supported on the floor by four auxiliary wheels with height-adjustable spindles and can be pulled out from under the vehicle.



   In this way, it is possible to create a sweeping brush for snow-clearing machines, which is better able to adapt to the shape of the roadway to be cleaned and, as a result, has the possibility of being cleaned by one
Snow plow to capture snow left on uneven roads.
