Description
NOVELTY IN MECHANICAL ROAD SWEEPING MACHINES
Technical Field of the Invention
The present invention relates to adding a system to mechanical road sweeping machines that perform sweeping by means of elevator and conveyor in order to prevent dust from spreading around, wherein said system is capable of vacuuming through a fan rotated by means of a hydro motor.
Prior Art
The main problem of mechanical road sweeping machines is that these machines spread dust around in areas where water sprayed from nozzles is insufficient during sweeping and while conveying the trash at elevator and conveyor sections subsequent to the sweeping phase. Sizes of the dust particles that scatter to the atmosphere are important, and this is controlled by means of several tests measuring particle sizes.
In the state of the art, the number of nozzles which serve the purpose of widening the washing area and preventing dust from scattering around, have increased, however, the amount of water contained inside the water tank decreased based on the increasing number of nozzles due to the fact that the volume of the water tank remains unchanged. Accordingly, increasing the number of nozzles decreased the work time of machines since mechanical road sweeping machine cannot continue working once their water tank is empty.
Another method implemented in the state of the art involves decreasing the speed of brushes of the mechanical road
sweeping machine thereby avoiding dust emission. However, decreasing the speed of brushes affects the performance of the mechanical road sweeping machine negatively.
Object of the Invention
The main object of the present invention is to prevent large dust particles from scattering around in areas where water sprayed from nozzles is insufficient during sweeping and while the trash is being conveyed at elevator and conveyor sections by developing a novel mechanical road sweeping machine.

Dust chamber (1), by the function thereof, is designed, in a form that becomes narrow from top to bottom so as to accumulate dust in the upward direction. Thus, dust particles that enter the chamber are ensured to accumulate in a narrower section located in the discharge area (15) of the dust chamber (1) . Dust chamber (1) may be manufactured from metal-derived materials. Connection slots (8) made of a curved plate are positioned on the dust chamber (1) so that hose connections may be made. The dust chamber (1) comprises welded nuts so that the connections of the observation port (22), right connection leg (12), left connection leg (13) and the cartridge filter (24) may be made. "U" shaped guides (23) which ensure that the cartridge filter (24) may be attached easily and that provide guidance for positioning the cartridge filter (24) properly are positioned inside the dust chamber (1) . The lock plate (18) located at the lower portion of the dust chamber (1) ensures that the discharge trap (16) moves without being dislodged. Plate holders located on the dust chamber (1) are utilized for fastening the discharge trap (16) to the dust chamber (1) . Another detail pertaining to the dust chamber (1) is that lifting lugs (25) are positioned on the dust chamber (1) .
Right connection leg (12), left connection leg (13) and the connector (14) ensure that the dust chamber (1) is rigidly mounted on the mechanical road sweeping machine. Right connection leg (12), left connection leg (13) and the connector (14) is manufactured to feature a certain degree of durability so as to ensure that they may carry the weight of the dust chamber (1) .
The dust chamber (1) which may feature various weights, may be carried via a crane by means of the lifting lugs (25) positioned thereon, and mounted easily.
The scroll (2) is designed to respond to cubical dilatation by increasing the airflow rate. The scroll (2) is a welded component that is manufactured at gradually increasing radii based on the diameter of the fan (6) . The scroll (2) may be manufactured from metal-derived materials. The scroll comprises a distance closure plate (28) so as to ensure that the fan does not reverse the air from the area in which the vacuuming is performed while the fan (6) is working (Figure
6) . The plate located on the scroll (2) is designed so as to allow the assembly and the disassembly of the fan.
Scroll outlet (9) is designed to be in a right-angled form by considering the fact that the air discharged from the scroll (2) does not cause any disturbance for the people located in the environment. The scroll outlet (9) guides the discharged air towards the front end of the machine and ensures that the velocity of the air that is discharged within the range of the next vehicle, is reduced and gets mixed with atmosphere. A grating plate (10) is positioned in front of the scroll outlet (9) in order to ensure that no living being enters the mechanical road sweeping machine and that no human may accidentally contact the fan (6).
The front vacuum inlet (3) and the rear vacuum inlet (4) are designed to vacuum the maximum amount of dust particles by considering the sizes of brushes (29) used on the machine. The front vacuum inlet (3) and the rear vacuum inlet (4) may be manufactured from metal-derived materials. Connection slots (8) made of a plate are also positioned on the front vacuum inlet (3) and the rear vacuum inlet (4) and hoses are
connected to vacuum inlets (3, 4) by means of welding the connection slots (8) to vacuum inlets (3, 4) .
Fan (6) and fan blades (7) are used in order to meet the targeted air flow rate and to create a vacuum. Fan blade (7) and dimensions, as well as the dimensions of the radial fan (6), may vary depending on the results of airflow analyses. Backswept fan blade (7) is used in the fan (6) of the mechanical road sweeping machine produced within the scope of the present invention. Recesses are positioned on the side covers of the fan (6) to which the tabs located on the fan blades (7) may be inserted.
The discharge trap (16) is the cover that allows for discharging the trash accumulated inside the dust chamber (1) at will. The discharge trap (16) may be manufactured from metal-derived materials. The discharge trap (16) functions by means of the guides.
The observation port (20) allows for instantaneously controlling the interior of the dust chamber (1) . The observation cover (22) is mounted on the observation port (20) located on the dust chamber (1) by means of bolts. When needed, the observation cover (22) may be opened and the dust that gets adhered to the interior of the chamber may be washed .
The dust chamber (1) is mounted on the fuel tank by means of the connector (14), on the right side of the mechanical road sweeping machine by means of the right connection leg (12) and on the left side of the mechanical road sweeping machine by means of the left connection leg (13) by using bolts. Dust that gets accumulated inside the chamber is discharged onto the elevator (17) by means of the sliding discharge trap (16)
located at the lower portion of the dust chamber (1) . When the trap reaches to the farthest position thereof, the hole located on the discharge trap (16) is moved to a co-centric position with the hole located on the lock plate (18) positioned at the lower portion of the dust chamber (1) and the discharge trap (16) may be fastened by means of the lock shaft (19) . Thus, the discharge trap (16) is prevented from opening accidentally or unintentionally without the intervention of the operator when the mechanical road sweeping machine is on the move. Guides (23) which are made of sheet metal plate and located inside the dust chamber (1), ensure that the cartridge filter (24) moves on the same axis. Said guides (23) made of sheet metal plate, carry the weight of the cartridge filter (24) while the cartridge filter (24) is being installed, thereby providing convenience to the operator. Cartridge filter (24) ensures that the accumulated dust does not get discharged from the scroll (2) . Nuts are welded to the dust chamber so as to enable the installation of the cartridge filter (24), and the cartridge filter may be installed by means of the holes located on the cartridge filter (24) . Said cartridge filter (24) which is suitably manufactured according to the dimensions of the mechanical road sweeping machine desired to be used, is created by spinning a carcass around the fiber material of varying thicknesses and density. The cartridge filter (24) is designed such that it may be removed and reinstalled when necessary. Vacuum hoses (5) are selected according to the results of airflow analyses conducted based on testing performed for the optimal flow capacity as well as the airflow rates. Vacuum hoses (5) are connected to the front vacuum inlet (3) and the rear vacuum inlet (4) from at least two points so as to vacuum the dust efficiently by taking advantage of a wider section. The front vacuum inlet (3) is positioned at the center of two brushes (29) . The location of the front vacuum inlet (3) is adjusted to be exposed to the
maximum amount of dust by considering the direction of rotation of brushes (29) . Identically, the rear vacuum inlet (4) which is positioned to the tail end of the rear brush (29) , is located to be exposed to the maximum amount of dust based on the direction of rotation of the brush (29) . Airborne dust particles initially get caught in the negative pressure at the entry of the front vacuum inlet (3) which has a wider section and move to the inside of the front vacuum inlet (3), and the sections of the front vacuum inlet (3) and the rear vacuum inlet (4) feature an ever-narrowing structure. Thus, the airborne dust particles that initially get caught in the negative pressure, accelerate as they proceed through the front vacuum inlet (3) and enter the vacuum hoses (5) . Since vacuumed dust particles which advance with high speed through the vacuum hoses (5) get abruptly dispersed into a broader volume once they enter the dust chamber (1), they decelerate and sink to the bottom of the dust chamber (1) . The fan (6) and the scroll (2) that create negative pressure are positioned on top of the dust chamber (1) . The hydro motor (27) that drives the fan (6) is connected to the fan (6) by means of the flange (26) installed to the fan (6) . The right- angled rotation at the output of the fan (6) is designed separately from the scroll (2) in order to facilitate assembly and disassembly operations. The connection of the fan (6) to the scroll (2) and the dust chamber (1) is made by means of bolts .
In brief, a dust chamber (1) is positioned on the mechanical road sweeping machine and said dust chamber (1) comprises a cartridge filter (24) . The vacuum obtained by means of the fan (6) positioned inside the scroll (2) on the dust chamber (1) is conveyed to the front vacuum inlet (3) and the rear vacuum inlet (4) by means of the vacuum hoses (5) . The front vacuum inlet (3) out of said vacuum inlets is positioned such that it
is centered between two brushes (29) on the front, whereas the rear vacuum inlet (4) is positioned such that remains behind the rear brush (29) . Dust that gets levitated while the sweeping operation is being performed, is vacuumed inside by means of the front vacuum inlet (3) and the rear vacuum inlet (4) . Dust particles that enter the dust chamber (1) by means of the vacuum hoses (5) sink to the bottom of the dust chamber (1), and those that remain airborne get caught by the cartridge filter (4) . Subsequent to this cycle, dust-free air vacuumed into the scroll (2) is released to the atmosphere through the scroll outlet (9) .
