Description

Technical Field

[0001] This application relates to the field of municipal road construction technology, and in particular to a road cleaning device. Background Technology

[0002] Road sweepers are a new type of high-efficiency cleaning equipment that integrates road sweeping, garbage collection, and transportation. Simply put, they are sweeping vehicles modified on special vehicle chassis to perform road sweeping functions. According to the driving method, they can be divided into automatic road sweepers, push-type road sweepers, and intelligent road sweepers. Among them, push-type road sweepers use tires to rotate belts, which drive the internal roller brush and the two front side brushes to rotate, thereby sweeping the garbage into the garbage bin inside the machine. The garbage is automatically cleaned up, requiring little human intervention. Sanitation workers only need to push it forward, which is much easier than cleaning with a traditional broom.

[0003] The patent document with authorization announcement number CN220301233U discloses a push-type road cleaning vehicle, which includes a spray module. The spray module is driven by a water pump to spray water, which can effectively achieve dust removal by spraying and has certain positive significance. However, the push-type device is mainly lightweight and convenient. Setting up a water pump requires setting up equipment such as a mobile power supply, which will undoubtedly increase the complexity of the entire device structure and also increase the manufacturing cost of the device.

[0016] The present application will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present application, and therefore only show the components relevant to the present application.

[0017] like Figure 1-8 As shown, a road cleaning device includes a vehicle body 1, with a sweeping wheel set 2 rotatably mounted on the front side of the vehicle body 1; a water tank 11 is mounted on the vehicle body 1, and a rotating shaft 62 is mounted on the rear side of the vehicle body 1. A flow hole 9 is radially passed through the rotating shaft 62, and a four-way pipe is mounted on the rotating shaft 62 at the position corresponding to the flow hole 9. One set of opposing pipes in the four-way pipe is rotatably connected to the rotating shaft 62, and the other set of opposing pipes is connected to the water tank 11 and the spray pipe 66 respectively.

[0018] The core structure of this road cleaning device includes a vehicle body 1, sweeping wheel assembly 2, water tank 11, rotating shaft 62, and four-way pipe. The sweeping wheel assembly 2, which is rotatably mounted on the front side of the vehicle body 1, sweeps away ground debris by rotating. The rotating shaft 62 on the rear side of the vehicle body 1 distributes water flow through a radially penetrating flow hole 9 in conjunction with the four-way pipe.

[0019] One set of opposing pipes of the four-way pipe is rotatably connected to the rotating shaft 62 to ensure that the four-way pipe remains fixed when the rotating shaft 62 rotates; the other set of opposing pipes are connected to the water tank 11 and the spray pipe 66 respectively, forming a water circuit of "water tank 11-four-way pipe-spray pipe 66".

[0020] When the vehicle body 1 moves, the rotating shaft 62 rotates synchronously through mechanical transmission. When the flow hole 9 is connected to a set of opposing pipes in the four-way pipe (i.e., parallel), water flows into the spray pipe 66. When perpendicular, the rotating shaft 62 blocks the four-way pipe. As the rotating shaft 62 rotates continuously, water flows continuously into the spray pipe 66, thus maintaining the cleaned road surface. This device does not require a water pump or power supply, simplifying the structure and reducing costs. At the same time, the rotating sealing design of the four-way pipe (such as a shaft seal) prevents water leakage and ensures the stability of the water circuit.

[0021] In some further embodiments, a collecting wheel 50 is provided inside the vehicle body 1 for rotation, and a dust collection hopper 10 is also provided on the vehicle body 1. The dust collection hopper 10 is provided with a connecting hole 100, and the dust collected by the collecting wheel 50 enters the dust collection hopper 10 through the connecting hole 100.

[0022] A collecting wheel 50, which rotates inside the vehicle body 1, works in conjunction with a dust collection hopper 10 to collect dust. The surface of the collecting wheel 50 is equipped with a scraper 5, which, when rotating, stirs up dust from the ground. The dust then enters the dust collection hopper 10 through a connecting hole 100. The dust collection hopper 10 is detachable for easy cleaning. This structure utilizes the rotational kinetic energy of the collecting wheel 50 to achieve automatic dust collection, eliminating the need for an additional power source, further simplifying the device and reducing energy consumption.

[0023] In some further embodiments, a first gear 7 is provided on the rotating shaft of the rear wheel of the vehicle body 1, and a second gear 70 is provided on the rotating shaft of the collecting wheel 50, with the first gear 7 and the second gear 70 meshing with each other.

[0024] A first gear 7 is mounted on the axle of the rear wheel of the vehicle body 1, and a second gear 70 is mounted on the axle of the collecting wheel 50; the two gears mesh together for transmission. When the vehicle body 1 moves, the rotation of the rear wheel drives the first gear 7 to rotate, which in turn drives the second gear 70 and the collecting wheel 50 to rotate. This design directly transmits the rotational kinetic energy of the rear wheel to the collecting wheel 50 through gear transmission, resulting in high transmission efficiency and a compact structure. The gear ratio can be adjusted according to actual needs; for example, a smaller gear can drive a larger gear to achieve speed reduction and torque increase, ensuring that the collecting wheel 50 operates stably at low speeds.

[0025] In some further embodiments, a first pulley 71 is also fitted on the rotating shaft of the collecting wheel 50. The first pulley 71 is provided with a first belt groove 73. The first belt groove 73 is connected to the second pulley 6 provided on the rotating shaft 62 via a first transmission belt 60.

[0026] When the collecting wheel 50 rotates, the first pulley 71 drives the second pulley 6 and the rotating shaft 62 to rotate via the first transmission belt 60, thereby driving the spray pipe 66 to spray water. This design achieves synchronous linkage between the collecting wheel 50 and the rotating shaft 62 through belt drive, avoiding the need for an additional power source; the belt is made of rubber, which has a buffering and shock-absorbing effect, reducing transmission noise; at the same time, belt drive allows for a larger center distance between the two shafts, which facilitates the arrangement of the internal structure of the vehicle body 1.

[0027] In some further embodiments, the top of the vehicle body 1 is provided with four L-shaped snap-fit ​​plates 111, and the water tank 11 is located in the area enclosed by the four L-shaped snap-fit ​​plates 111.

[0028] The water tank 11 has an inlet 110 at the top and an outlet at the bottom. The outlet is connected to one of the pipes in the four-way pipe via a flexible hose.

[0029] Four L-shaped clamping plates 111 are installed on the top of the vehicle body 1. The water tank 11 is fixed to the vehicle body 1 via the L-shaped clamping plates 111 to prevent shaking during driving. A water inlet 110 is provided at the top of the water tank 11 for easy water filling, and a water outlet is provided at the bottom, which is connected to a four-way pipe via a hose. The L-shaped clamping plates 111 are made of elastic material (such as plastic), which clamps the water tank 11 by deformation, simplifying the installation process. The hose adopts a corrugated design to adapt to the vibration of the vehicle body 1 and prevent water circuit breakage. This structure ensures a stable water supply to the water tank 11, while also facilitating disassembly and maintenance.

[0030] In some further embodiments, a rotating support 61 is provided on the rear side of the vehicle body 1, and the rotating shaft 62 is mounted on the vehicle body 1 through the rotating support 61; the four-way pipe is mounted on the vehicle body 1 through a clamp 67.

[0031] A rotating support 61 is installed at the rear of the vehicle body 1. A rotating shaft 62 is mounted on the rotating support 61 via bearings to ensure smooth rotation. The four-way pipe is fixed to the vehicle body 1 by clamps 67 to prevent displacement due to rotation of the rotating shaft 62. The rotating support 61 is made of metal, providing high strength. The clamps 67 feature a quick-release design (such as a butterfly nut) for easy adjustment of the four-way pipe angle. This structure ensures stable water circuit connections while simplifying the assembly process.

[0032] The four-way pipe system specifically includes a first pipe 63 and a second pipe 64, as well as another set of four pipes and a fourth pipe. The first pipe 63 is connected to the water tank 11 via a flexible hose, the second pipe 64 is connected to the spray pipe 66, and the third and fourth pipes are rotatably connected to the rotating shaft 62, and a shaft seal 65 is provided to prevent water leakage.

[0033] In some further embodiments, the sweeping wheel assembly 2 includes two sweeping wheels spaced apart, and a steering pulley 21 is provided on the vehicle body 1; a second groove 72 is provided on the first pulley 71, and the steering pulley 21 is connected to the first groove 73 through a second transmission belt 720; a third pulley 3 is provided on the rotating shaft of the sweeping wheel, and the third pulley 3 is connected to the steering pulley 21 through a third transmission belt 20.

[0034] The sweeping wheel assembly 2 includes two sweeping wheels. A steering pulley 21 is installed on the vehicle body 1. A first pulley 71 drives the steering pulley 21 through a second transmission belt 720, and the steering pulley 21 then drives the sweeping wheels to rotate through a third transmission belt 20. This design achieves the linkage between the sweeping wheels and the collection wheel 50 through multi-stage belt transmission. When the vehicle body 1 moves, the rear wheels drive the collection wheel 50 to rotate, which in turn drives the sweeping wheels to rotate and work through the second transmission belt 720 and the third transmission belt 20.

[0035] The steering pulley 21 can adjust the transmission direction so that the two sweeping wheels rotate in opposite directions to sweep dust and impurities toward the central area, which is convenient for collection by the subsequent collection wheel 50.

[0036] In some further embodiments, a telescopic joint 4 is provided on the rotating shaft of the sweeping wheel. The telescopic joint 4 includes a sliding sleeve 82 and a sliding post 8. One end of the sliding post 8 is connected to one section of the rotating shaft, and the other end is slidably engaged with the sliding sleeve 82. One end of the sliding sleeve 82 is connected to the other opposite section of the rotating shaft. A spring 81 is provided in the sliding sleeve 82.

[0037] The sliding column 8 is radially provided with a limiting hole, and the sliding sleeve 82 is radially provided with a limiting slot 83. A limiting shaft 80 is provided in both the limiting hole and the limiting slot 83, and the limiting shaft 80 and the limiting slot 83 are in sliding fit.

[0038] Spring 81 is housed within sliding sleeve 82, providing axial preload. Sliding post 8 has a limiting hole, and sliding sleeve 82 has a limiting slot 83. Limiting shaft 80 passes through the limiting hole and limiting slot 83 to prevent sliding post 8 from dislodging. When the sweeper wheel encounters an obstacle, sliding post 8 compresses spring 81, causing it to retract into sliding sleeve 82 for cushioning. After the obstacle passes, spring 81 resets, pushing the sweeper wheel back to its original position. This structure improves the sweeper wheel's adaptability, prevents damage from hard impacts, and extends its service life.

[0039] The plane in which the sweeping wheel rotates is a horizontal plane of rotation.

[0040] It should be noted that in this embodiment, the drive shaft of the collecting wheel 50 and the rotating shaft of the steering pulley 21 are connected to the vehicle body 1 through strip holes to meet the tensioning of the aforementioned drive belt.

[0041] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
