Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of road sanitation and cleaning equipment, specifically a road sweeping device. Background Technology
[0002] Currently, sweepers have become essential equipment for sanitation operations, offering numerous advantages such as good cleaning results and labor savings. Existing sweepers mostly use disc-type and roller brushes to clean roads. These sanitation vehicles are not only expensive to manufacture and consume a lot of energy, but they can also only clean relatively loose dust, garbage, and leaves.
[0003] Therefore, people began using brushes to sweep away dust or leaves. For example, CN 105625234B discloses a tracked brush-type road sweeper, which uses a diesel engine to drive a hydraulic pump, which provides pressurized oil to a hydraulic motor via a hydraulic system. The hydraulic motor drives a drive wheel to rotate, which in turn drives a brush belt. A second hydraulic cylinder controls the distance between the bottom surface of the brush belt and the road surface, ensuring that the rubber bristles on the brush belt contact the road surface during operation, thus performing the sweeping work. This sweeps dust, leaves, and other debris from the road surface to low-lying areas on both sides of the road.
[0004] However, the brush setup in this patent cannot handle heavily polluted road surfaces, such as mud spilled by dump trucks in front of construction sites or during snow removal operations. Furthermore, it cannot thoroughly clean uneven road surfaces. Utility Model Content
[0005] The purpose of this invention is to provide a road sweeping device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A road sweeping device includes two support frames, with a drive wheel and a driven wheel provided at both ends of each support frame. A chain is installed on the outer periphery of the drive wheel and the driven wheel, and the chain meshes with the drive wheel or the driven wheel. The two drive wheels are connected by a drive shaft.
[0008] A brush is installed between the two chains and is fixed to the outer periphery of the chains by screws. A load-bearing wheel and a support wheel are provided between the support frame and the chains. The load-bearing wheel is installed below the support frame and the support wheel is located above the support frame. The load-bearing wheel or the support wheel meshes with the chains.
[0009] Each of the aforementioned support frames is equipped with two traveling wheels and two automatic leveling components. One end of the automatic leveling component is connected to a hydraulic cylinder, and the other end is connected to the support frame.
[0010] In one possible implementation, a first base plate is provided between the two support frames, and an engine is provided on the first base plate. The front end of the engine is connected to a speed reducer, and the output end of the speed reducer is connected to the drive shaft via a transmission chain.
[0011] In one possible implementation, a protective cover is provided above the support frame, and the protective cover is fixed to the support frame by screws.
[0012] In one possible implementation, a second base plate is provided between the two support frames, and a high-pressure water pump is installed on the second base plate. The outlet of the high-pressure water pump is connected to a high-pressure nozzle through a water supply pipe. The high-pressure nozzle is installed on the outer periphery of the protective cover, and the water outlet direction of the high-pressure nozzle is towards the brush.
[0013] In one possible implementation, a third base plate is provided between the two support frames, and a hydraulic pump is mounted on the third base plate, the output end of which is connected to the hydraulic cylinder.
[0014] In one possible implementation, the hydraulic cylinder has a connector at one end away from the automatic leveling component, and the hydraulic cylinder is connected to the sweeper chassis via the connector.
[0015] In one possible implementation, the support frame is provided with a trapezoidal beam, and the support wheel is mounted on the trapezoidal beam.
[0016] In one possible implementation, the automatic leveling component is a spring that abuts against the hydraulic cylinder.
[0017] Compared with the prior art, the present invention has the following advantages:
[0018] By installing load-bearing wheels, support wheels, and an automatic leveling component between the support frame and the chain, the sweeping device can adapt to complex road conditions. When operating on uneven surfaces, the support wheels adjust the chain tension to maintain a suitable level, while the load-bearing wheels press the chain firmly to ensure the brush is in constant contact with the road surface. The traveling wheels, in conjunction with the automatic leveling component, reduce bumps during the sweeping process, ensuring effective cleaning. Furthermore, the combination of a high-pressure water pump and nozzles enables this sweeping device to thoroughly clean heavily soiled surfaces. Attached Figure Description

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0024] like Figure 1-3 As shown, a road sweeping device includes two support frames 1. The main body of each support frame 1 is a horizontal beam. The two parallel horizontal beams can be connected to a vertical support rod to form a rectangular frame. A drive wheel 2 and a driven wheel 3 are provided at both ends of each support frame 1. A chain 4 is mounted on the outer periphery of each drive wheel 2 and driven wheel 3, and the chain 4 meshes with either the drive wheel 2 or the driven wheel 3. The two drive wheels 2 are connected by a drive shaft 14. The drive wheel 2 and driven wheel 3 are located inside the horizontal beam and are fixedly mounted to the horizontal beam by a mounting bracket. Specifically, one end of the drive shaft 14 is inserted into a mounting component, which is then fixed to the horizontal beam by screws.
[0025] A brush 7 is installed between the two chains 4, and the brush 7 is fixed to the outer periphery of the chain 4 by screws. A load-bearing wheel 5 and a support wheel 6 are provided between the support frame 1 and the chain 4. The load-bearing wheel 5 is installed below the support frame 1, and the support wheel 6 is positioned above the support frame 1. The load-bearing wheel 5 or the support wheel 6 meshes with the chain 4. There are three load-bearing wheels 5, evenly spaced between the drive wheel 2 and the driven wheel 3. There are two support wheels 6, positioned between adjacent load-bearing wheels 5. The load-bearing wheels 5 and the support wheels 6 effectively support the chain 4 and provide a force towards the outer periphery of the chain 4 during operation, ensuring that the chain 4 does not move inward due to road unevenness. This ensures that the cleaning device of this invention can adapt to various road conditions.
[0026] A first base plate 20 is provided between the two support frames 1. An engine 15 is mounted on the first base plate 20. The front end of the engine 15 is connected to a reducer 16, and the output end of the reducer 16 is connected to the drive shaft 14 via a transmission chain 19. A protective cover 11 is provided above the support frame 1, and the protective cover 11 is fixed to the support frame 1 with screws. The protective cover 11 protects the cleaning device and prevents damage to its internal structure. A second base plate 21 is provided between the two support frames 1. A high-pressure water pump 17 is mounted on the second base plate 21. The outlet of the high-pressure water pump 17 is connected to a high-pressure nozzle 13 via a water pipe. The high-pressure nozzle 13 is installed on the outer periphery of the protective cover 11, and the water outlet direction of the high-pressure nozzle 13 is towards the brush 7. The high-pressure water pump 17 and the high-pressure nozzle 13 can flush silt and other debris into the drainage ditches on both sides of the road, improving the efficiency of road cleaning.
[0027] Furthermore, each of the aforementioned support frames 1 is equipped with two traveling wheels 12 and two automatic leveling components 10. One end of each automatic leveling component 10 is connected to a hydraulic cylinder 9, and the other end is connected to the support frame 1. A third base plate 22 is provided between the two support frames 1, and a hydraulic pump 18 is installed on the third base plate 22. The output end of the hydraulic pump 18 is connected to the hydraulic cylinder 9. A connecting member 23 is provided at the end of the hydraulic cylinder 9 away from the automatic leveling component 10, and the hydraulic cylinder 9 is connected to the sweeper chassis through the connecting member 23. The automatic leveling component 10 can be a spring, which abuts against the hydraulic cylinder 9. The automatic leveling component 10 and the hydraulic cylinder 9 are used to dampen the vibrations of the sweeper during operation, ensuring that the sweeping device is always relatively level with the ground.
[0028] Furthermore, a trapezoidal beam 8 is provided on the support frame 1, and the support wheel 6 is mounted on the trapezoidal beam 8. By setting the trapezoidal beam 8, the chain 4 forms a trapezoidal shape, thereby further increasing the cleaning time of the brush 7, and also increasing the stability of the entire road sweeping device, making the road sweeping device more adaptable to uneven road surfaces.
