Description
A SWEEPER
The invention relates to a movable sweeper for cleaning large flat areas such as airport runways. The sweeper has a broad cylindrical brush which is rotated its axis, a flap arrangement for leading loose water, snow and particles to the side and supporting wheels by means of which the working height of the brush is adjusted.
Known sweepers have separate adjustable support wheels and separate adjustable flap constructions in front of the rotatable brush. The height of the brush from the cleaned surface is adjusted and maintained by means of the support wheels. The position of said wheels in relation to the frame of the machine can be changed. Height adjustment allows different contact areas to be achieved i.e. the length of the contact surface in the working direction of the brush can be adjusted to be larger or smaller.
The rotating brush in use may carry with it light particles that are returned to the cleaned surface. In order to prevent this, the flap arrangement in front of the brush is used to dislodge loose material from the brush. A similar arrangement may be used behind the brush. When the brush wears, the separate brush wires becomes shorter and thus the brush diameter becomes smaller. It follows that the support wheels have to be lifted in relation to the frame and the flap arrangements have to be moved nearer the brush. The sweepers of earlier known types have separate adjustments for the support wheels and flaps which is inconvenient.

DESCRIPTION OF THE INVENTION
In the figure 1 there is shown a sweeper having a frame 7, a rotatable brush 1 mounted in bearings on the frame, a hydraulic motor 31 to rotate said brush and a support wheel 2 coupled to the frame. The support wheel can be lifted and lowered in relation to the frame 7. A sleeve 19 is fixed to the frame 7 and a vertical axle 24 of the support wheel assembly is movable vertically within the sleeve at the lower end of the vertical axle are bearing 20 that allow the wheel 2 to turn. Spring 21 keeps the wheel in the intended direction of travel.
The frame 7 includes a horizontal axle 3, the outer surface of which carries an arm 18. A connection rod 17 to the support wheel height adjustment system connected to the arm 18 at a joint 16. By rotation of the axle 3, the support wheel 2 can be lifted and lowered.
Rotation of the axle is effected by an activator, which in this case is a hydraulic cylinder 4. The upper end of the cylinder is fixed to said frame 7 and the lower end is fixed at a joint 5 to an arm 6 fixed on the axle 3.
In front of the brush there is a flap arrangement 11 which can be moved horizontally forward and backwards. The frame 7 has guiding means, rails or similar gliding bars 27 on which the flap 11 can be moved. A gliding sleeve 29 is mounted on the bar 27 and fixed to the flap 11. Motion is transmitted to the flap by a rod 12 from an arm 15 fixed to the outer surface of the axle 3. Between arm 15 and rod 12 there is a joint 14. By turning of the axle 3 the flap arrangement 11 is moved towards or away from the brush.
The flap arrangement comprises the front flap 11 and a shield 23 extending over the brush and partly to the side.
Behind the brush 1 there is a rear flap arrangement which can collect loose particles and water, and which comprises a channel 8 and a shield 22. The shield 22 extends over the brush. The flap arrangement 8,22 can be moved towards the brush axle by means of an arm 30 which is articulated to the frame by a joint 28. The motion for the flap 8,22 is transmitted by a rod 9 from the arm 13 to which arm the rod 9 is fixed by a joint 10. The arm 13 is fixed to the outer surface of the axle 3.
As an alternative embodiment the rear flap arrangement 8,22 can also be fixed on the gliding bar 27 through another sleeve 29 instead of arm 30 and joint 28, so that linear motion of the rear flap is possible.
When the adjusting axle 3 is rotated by=the cylinder 4 and arm 6, the arm 13,15,18 (Fig. 2a) move simultaneously. By the lengths of said arms the motion distances of the wheel and the flaps can be adjusted. Preferably, the motion distances of the flaps 11,8 towards the brush centre are the same as the adjusted distance by which the support wheel 2 moves upwardly. The motion distances of the flaps 11,8 depend on the distance the wheel 2 moves in the vertical direction. It is advantageous if the lengths of each connection rods 9,12 and 17 is also adjustable for example by equipping at least one end of each connection rod with a thread 35 and providing a screwed threaded coupling sleeve 36 on the thread (Fig. 1).
Fig. 2a shows the rotatable adjusting axle 3, arms 6,13,15 and 18 thereon and connection rods 9,12,17 connected by joints 5,10,14 to the arms and cylinder 4. In the figure 2b the connection rods are removed.
In Fig. 3 there is shown as a top view the whole sweeper.
The adjusting axle 3 has bearings on its both ends and is rotatably coupled to the frame 7 by the bearings. The sweeper can be very wide, for example 4 - 6 meters. It is therefore advantageous to use two or more parallel mounted rods for the flaps and two activators 4 as shown in Fig. 3.
Figure 4 shows a flap construction system comprising hinged front flap 11 which is moved by means of the rod 12. The hinge point 32 is on the flap top and said flap 11 is turned by means of the rod 12. In order to assure reliable operation the system may comprise, as shown, auxiliary articulated arms 33 and 34. The flap 11 can be raised for facilitating removal of the brush.
As an activator, a screw system producing linear motion can be used. Also an embodiment is possible in which the activator 4 is first connected to move for example the vertical axle 24 of the wheel 2 to adjust the brush height.
In this case, the rod 17 rotates the axle 3. Also the activator 4 can be connected first to move one of the flap arrangements, in which case the rod 9 or 12 can be used to turn the axle 3.
In front of the brush there is a flap arrangement 11 which can be moved horizontally forward and backwards. The frame 7 has guiding means, rails or similar gliding bars 27 on which the flap 11 can be moved. A gliding sleeve 29 is mounted on the bar 27 and fixed to the flap 11. Motion is transmitted to the flap by a rod 12 from an arm 15 fixed to the outer surface of the axle 3. Between arm 15 and rod 12 there is a joint 14. By turning of the axle 3 the flap arrangement 11 is moved towards or away from the brush.
The flap arrangement comprises the front flap 11 and a shield 23 extending over the brush and partly to the side.
Behind the brush 1 there is a rear flap arrangement which can collect loose particles and water, and which comprises a channel 8 and a shield 22. The shield 22 extends over the brush. The flap arrangement 8,22 can be moved towards the brush axle by means of an arm 30 which is articulated to the frame by a joint 28. The motion for the flap 8,22 is transmitted by a rod 9 from the arm 13 to which arm the rod 9 is fixed by a joint 10. The arm 13 is fixed to the outer surface of the axle 3.
As an alternative embodiment the rear flap arrangement 8,22 can also be fixed on the gliding bar 27 through another sleeve 29 instead of arm 30 and joint 28, so that linear motion of the rear flap is possible.
When the adjusting axle 3 is rotated by=the cylinder 4 and arm 6, the arm 13,15,18 (Fig. 2a) move simultaneously. By the lengths of said arms the motion distances of the wheel and the flaps can be adjusted. Preferably, the motion distances of the flaps 11,8 towards the brush centre are the same as the adjusted distance by which the support wheel 2 moves upwardly. The motion distances of the flaps 11,8 depend on the distance the wheel 2 moves in the vertical direction. It is advantageous if the lengths of each connection rods 9,12 and 17 is also adjustable for example by equipping at least one end of each connection rod with a thread 35 and providing a screwed threaded coupling sleeve 36 on the thread (Fig. 1).
Fig. 2a shows the rotatable adjusting axle 3, arms 6,13,15 and 18 thereon and connection rods 9,12,17 connected by joints 5,10,14 to the arms and cylinder 4. In the figure 2b the connection rods are removed.
In Fig. 3 there is shown as a top view the whole sweeper.
The adjusting axle 3 has bearings on its both ends and is rotatably coupled to the frame 7 by the bearings. The sweeper can be very wide, for example 4 - 6 meters. It is therefore advantageous to use two or more parallel mounted rods for the flaps and two activators 4 as shown in Fig. 3.
Figure 4 shows a flap construction system comprising hinged front flap 11 which is moved by means of the rod 12. The hinge point 32 is on the flap top and said flap 11 is turned by means of the rod 12. In order to assure reliable operation the system may comprise, as shown, auxiliary articulated arms 33 and 34. The flap 11 can be raised for facilitating removal of the brush.
As an activator, a screw system producing linear motion can be used. Also an embodiment is possible in which the activator 4 is first connected to move for example the vertical axle 24 of the wheel 2 to adjust the brush height.
In this case, the rod 17 rotates the axle 3. Also the activator 4 can be connected first to move one of the flap arrangements, in which case the rod 9 or 12 can be used to turn the axle 3.
