Abstract
Description
Technical Field
[0001] This utility model relates to the field of road sweeping equipment, and more specifically, to a road sweeper. Background Technology
[0002] Road surfaces often contain hard debris such as stones. To prevent vehicles from being damaged or causing accidents by flying debris during driving, road sweepers are usually used to clean up the debris on the road.
[0003] Conventional road sweepers operate at low speeds, resulting in small-scale and low-velocity splashing of hard debris during sweeping. Simple baffles on the sweeper can effectively block this splashing debris. However, as the operating speed of the road sweeper increases, the splashing speed of hard debris increases, and the splashing range widens. The simple baffles on the sweeper are then ineffective in blocking this splashing debris, which can easily injure vehicles or pedestrians. Utility Model Content

[0043] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.
[0044] Urban roads are often littered with fallen leaves, dust, pebbles, and other debris. To maintain urban aesthetics and sanitation, and to prevent vehicles from being damaged or causing accidents by flying debris during driving, road sweepers are typically used to clean up the debris. During operation, the sweeping discs, tires, and suction nozzles of road sweepers all generate flying debris. Conventional road sweepers operate at speeds less than 10 km / h, resulting in slow speeds and a small area of debris splash. Therefore, the anti-splash mechanisms on conventional road sweepers are usually simple in design, with baffles made primarily of fabric-reinforced rubber or canvas.
[0045] When a road sweeper operates at high speed, the debris it kicks up flies upwards and into the chassis frame. Conventional anti-splash mechanisms are ineffective in blocking this debris, which instead causes stones, dust, and other garbage to accumulate inside the frame, leading to debris buildup. This accumulated debris is difficult to clean, and the high-speed impact of the debris on components installed inside the frame increases the vehicle's failure rate. In addition, the debris can also bounce laterally, hitting other vehicles on the side and rear of the sweeper, seriously affecting driving safety.
[0046] In view of this, an embodiment of the present invention provides a road sweeper that can solve the above problems, which will be described in detail below.
[0047] Please refer to Figure 1 and Figure 2 An embodiment of this utility model provides a road sweeper, comprising: a vehicle body 1, a first blocking component 2, a second blocking component 3, and a longitudinal blocking component 5. The vehicle body 1 includes a chassis 10, front wheels 11, rear wheels 12, a sweeping brush 13, and a central suction nozzle 14. The sweeping brush 13 is located between the front wheels 11 and the rear wheels 12 and is mounted on the chassis 10. The central suction nozzle 14 is located between the sweeping brush 13 and the rear wheels 12. The first blocking component 2 is disposed in front of the sweeping brush 13, and laterally blocks splashes in front of the sweeping brush 13 to prevent splashes from flying towards the front of the vehicle. The second blocking component 3 is disposed behind the sweeping brush 13 and connected to the central suction nozzle 14, and laterally blocks splashes behind the sweeping brush 13. The longitudinal blocking component 5 is disposed on the side of the sweeping brush 13, extending along the length of the vehicle body 1, and longitudinally blocks splashes on the side of the sweeping brush 13.
[0048] In this embodiment, the vehicle body 1 also includes a rear suction nozzle 15 and a garbage bin 16. The rear suction nozzle 15 is located behind the rear wheel 12. The upper parts of the middle suction nozzle 14 and the rear suction nozzle 15 are both connected to the chassis 10. The garbage bin 16 is located at the rear of the vehicle. The sweeping brush 13 collects debris on the road into the range that the middle suction nozzle 14 can suck up. The middle suction nozzle 14 is used to suck the debris on the road into the garbage bin 16 at the rear of the vehicle. The rear suction nozzle 15 is used to suck up any debris that is missed by the middle suction nozzle 14 into the garbage bin 16, ensuring thorough cleaning.
[0049] A third blocking component 4 is also provided between the rear wheel 12 and the rear suction nozzle 15. The third blocking component 4 blocks and gathers the debris near the rear suction nozzle 15 so that the rear suction nozzle 15 can suck up the debris more efficiently.
[0050] The first blocking component 2, the second blocking component 3, and the third blocking component 4 block flying debris in the direction of travel of the vehicle body 1, while the longitudinal blocking component 5 blocks flying debris in the direction perpendicular to the direction of travel of the vehicle body 1. Together, these components limit the range of flying debris to the vicinity of the sweeping brush 13, preventing injury to passing vehicles or pedestrians. This sweeper can safely perform sweeping operations even at high speeds, effectively blocking flying debris.
[0051] It should be noted in advance that, in this embodiment, "front" refers to the side closer to the front of the vehicle, "rear" refers to the side closer to the rear of the vehicle, and "side" refers to the area between the front and rear of the vehicle. In this embodiment, the front view of the first blocking component 2, the second blocking component 3, the third blocking component 4, and the longitudinal blocking component 5 refers to the view from which an observer stands in front of the front of the vehicle and faces the front of the vehicle. The side view of the first blocking component 2, the second blocking component 3, the third blocking component 4, and the longitudinal blocking component 5 refers to the view from which an observer stands on the left or right side of the vehicle body 1.
[0052] The second blocking assembly 3, the third blocking assembly 4, and the longitudinal blocking assembly 5 can all be raised and lowered relative to the bottom plane of the vehicle body 1. When the sweeper is in sweeping operation, the second blocking assembly 3, the third blocking assembly 4, and the longitudinal blocking assembly 5 are lowered relative to the ground, thereby more effectively blocking the splashing of debris. When the sweeper is not in operation, the second blocking assembly 3, the third blocking assembly 4, and the longitudinal blocking assembly 5 are raised relative to the ground, increasing their ground clearance and preventing wear and tear during driving, thus increasing their service life.
[0053] refer to Figure 3 and Figure 4 The first blocking component 2 includes a first baffle 20, a first bracket 21 and a support net 22. The first baffle 20 and the support net 22 are both connected to the first bracket 21. The support net 22 is stacked and connected to the first baffle 20 to support the first baffle 20. The first bracket 21 is connected to the chassis 10.
[0054] For example, the first support 21 is a rectangular frame structure welded from four square steel pipes. A diagonal branch pipe and a vertical connecting pipe are welded to the side of the rectangular frame. The other end of the diagonal branch pipe is welded to the vertical connecting pipe, thus increasing the stability of the connection between the vertical connecting pipe and the rectangular frame structure. The vertical connecting pipe has threaded holes for easy connection to the chassis 10. When the first blocking component 2 needs to be mounted on the chassis 10, the vertical connecting pipe can be directly connected to the chassis 10 using bolts. The first baffle 20 is a rectangular plate, fixed to the side of the rectangular frame structure with screws or bolts to prevent damage from flying debris. The first baffle 20 may be torn apart by wind when the sweeper is traveling at high speed. At least one layer of support net 22 is laid between the first baffle 20 and the rectangular frame structure. The support net 22 can be made of crisscrossing wire mesh. The support net 22 is also connected to the rectangular frame structure. The support net 22 is used to support the first baffle 20 and prevent the first baffle 20 from being torn apart by wind when the sweeper is traveling at high speed. At the same time, the upper part of the support net 22 is connected to the top steel pipe of the first bracket 21 to reduce the wind resistance caused by the support net 22 when the sweeper is traveling. In addition, the support net 22 also has a certain blocking effect on the splashes.
[0055] In this embodiment, the first blocking component 2 is disposed between the front wheel 11 and the sweeping brush 13. When driving, the splashes carried by the front wheel 11 splash towards the rear of the vehicle body 1. Therefore, the first blocking component 2 can be used to block the splashes carried by the front wheel 11 to protect the vehicle body, and also to block the splashes agitated by the sweeping brush 13 to prevent the splashes from splashing towards the front wheel 11.
[0056] refer to Figure 5 and Figure 6 and combined Figure 2 The second blocking assembly 3 includes a second baffle 30, a second bracket 31, and a second pressure plate 32. The second baffle 30 is disposed on the second bracket 31 and is inclined relative to the bottom plane of the vehicle body 1. The second pressure plate 32 presses against the outside of the second baffle 30 and is connected to the second bracket 31. The second pressure plate 32 increases the contact area of the second baffle 30, thereby preventing the wind from tearing the second baffle 30 during the operation of the sweeper. The lower end of the second bracket 31 is rotatably connected to the middle suction nozzle 14. The middle suction nozzle 14 is provided with a hinge seat, and the lower end of the second bracket 31 is hinged to the hinge seat of the middle suction nozzle 14.
[0057] The second baffle 30 is inclined to form an angle with the ground. The angle is greater than 0° and less than 90°. For example, the angle is 30°, 45°, or 60°. Because the second baffle 30 is inclined, even if the debris that hits the second baffle 30 is not sucked up by the central suction nozzle 14, the debris will still fly towards the ground and will not fly towards the outside of the sides of the vehicle body 1. This will not pose a risk to passing vehicles or pedestrians. In addition, the second baffle 30 can also prevent debris from entering the chassis 10 and protect the internal components of the chassis 10.
[0058] Furthermore, since the lower end of the second bracket 31 is connected to the middle suction nozzle 14, the movement of the middle suction nozzle 14 can drive the second bracket 31 to move accordingly, and the movement of the second bracket 31 can drive the second baffle 30 to move. The middle suction nozzle 14 can move closer to the ground during operation, and the second bracket 31 also moves closer to the ground. The second baffle 30 also moves closer to the ground along with the second bracket 31, reducing the distance between the second baffle 30 and the ground, thereby enhancing the blocking effect of the second baffle 30 on splashes.
[0059] Optionally, the second baffle 30 includes an inclined upper half 301 and an inclined lower half 302. The inclined upper half 301 and the inclined lower half 302 can be integrally formed or connected by welding or other methods. The inclined lower half 302 is bent relative to the inclined upper half 301, and the angle of inclination between the inclined lower half 302 and the ground is greater than the angle of inclination between the inclined upper half 301 and the ground. This arrangement can block splashes from flying upwards or to the sides from multiple directions. The lower end of the inclined lower half 302 extends from the front side of the central suction nozzle 14 to below the central suction nozzle 14, which not only makes the structure more compact but also protects the central suction nozzle 14 from the impact of splashes.
[0060] refer to Figure 7 The third blocking assembly 4 includes a third baffle 40, a third bracket 41, a third pressure plate 42, and a third connecting rod 43. The third baffle 40 is disposed on the third bracket 41 and is inclined relative to the bottom plane of the vehicle body 1. The third pressure plate 42 presses on the outside of the third baffle 40 and is connected to the third bracket 41. The third bracket 41 is connected to the third connecting rod 43. The lower end of the third connecting rod 43 is rotatably connected to the rear suction nozzle 15.
[0061] For example, the third bracket 41 is a bent plate. The upper part of the bent third bracket 41 is bolted to the third connecting rod 43. The third baffle 40 is attached to the side of the third bracket 41 and bolted to the third bracket 41. The third pressure plate 42 presses on the outside of the third baffle 40. The third pressure plate 42 presses the third baffle 40 onto the third bracket 41 to increase the contact area between the third baffle 40 and the third bracket 41, thereby increasing the stability of the connection of the third baffle 40. The third link 43 is inclined, with its lower end rotatably connected to the rear suction nozzle 15 and its upper end rotatably connected to the chassis 10. The third baffle 40 forms an inclined angle with the ground, which is greater than 0° and less than 90°, for example, 45°, 60°, or 75°. Because the third baffle 40 is inclined, even if the debris hitting the third baffle 40 is not sucked up by the rear suction nozzle 15, the debris will still splash towards the ground and will not splash towards the left and right sides of the vehicle body 1 or upward into the chassis 10. Since the third bracket 41 is mounted on the rear suction nozzle 15, the third bracket 41 can move together with the rear suction nozzle 15. Since the rear suction nozzle 15 can move closer to the ground during operation, when the rear suction nozzle 15 moves closer to the ground, the third bracket 41 will also move closer to the ground. The third baffle 40 mounted on the third bracket 41 will also move closer to the ground along with the third bracket 41, reducing the distance between the third baffle 40 and the ground, thereby enhancing the blocking effect of the third baffle 40 on splashes.
[0062] Optionally, the angle between the lower half of the third baffle 40 and the ground is greater than the angle between the upper half and the ground. This arrangement can block splashes from flying upwards or to the sides from multiple directions. At the same time, the bending arrangement of the third baffle 40 can avoid the rear suction nozzle 15, so that the lower half of the third baffle 40 extends from the front side of the rear suction nozzle 15 to below the rear suction nozzle. This not only makes the structure more compact, but also protects the rear suction nozzle 15.
[0063] refer to Figures 8 to 11The longitudinal blocking assembly 5 blocks splashes perpendicular to the driving direction. The longitudinal blocking assembly 5 includes a longitudinal baffle 50, a longitudinal frame 51, a swing arm 52, a longitudinal pressure plate 53, and a mounting base 54. The longitudinal frame 51 can be a rectangular frame structure welded from four square steel pipes. The longitudinal baffle 50 is a rectangular plate, bolted to the rectangular frame structure. The longitudinal pressure plate 53 covers the outside of the longitudinal baffle 50 and connects to the longitudinal frame 51, preventing the longitudinal baffle 50 from detaching from the rectangular frame structure. The upper part of the longitudinal frame 51 is connected to the swing arm 52, and the upper end of the swing arm 52 is provided with a mounting base 54. The swing arm 52 and the mounting base 54 are rotatably connected, for example, hinged. The mounting base 54 also has screw holes, allowing it to be bolted to the chassis 10. The structure of the swing arm 52 and the mounting base 54 is not limited in this embodiment; angle steel plates or other suitable components can be used.
[0064] In this embodiment, a pull rope 55 is also connected to the longitudinal frame 51. One end of the pull rope 55 is connected to the longitudinal frame 51, and the other end of the pull rope 55 is connected to the central suction nozzle 14. A column is provided on the central suction nozzle 14. The end of the pull rope 55 is bent into a loop and looped onto the column. When the central suction nozzle 14 moves down, it will drag the longitudinal frame 51 down through the pull rope 55, so that the distance between the longitudinal baffle 50 and the ground is reduced, thereby enhancing the blocking effect on the splashes. When the central suction nozzle 14 moves up, the longitudinal frame 51 will automatically reset and move up, and the distance between the longitudinal baffle 50 and the ground will increase, preventing the longitudinal baffle 50 from being worn on the ground.
[0065] Optionally, the first baffle 20, the second baffle 30, the longitudinal baffle 50, and the third baffle 40 are all energy-absorbing plates. When the splashing material comes into contact with the energy-absorbing plate, it can absorb the kinetic energy of the splashing material, thereby reducing the splash range and collecting the splashing material near the central suction nozzle 14 or the rear suction nozzle 15 for easy suction into the waste bin 16. The energy-absorbing plate needs to have a certain degree of elasticity to avoid being broken by the splashing material in a short time. For example, the energy-absorbing plate can be made of rubber or other energy-absorbing materials.
[0066] The road sweeper provided by the embodiments of this utility model can effectively block the splashing of debris in all directions, increasing the safety of operation, and also prevent the splashing debris from entering the chassis 10 of the vehicle body 1. Compared with the existing conventional road sweepers, this road sweeper can operate on highways with guaranteed safety.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
