Description

Technical Field

[0001] This utility model belongs to the field of cleaning equipment technology, specifically relating to an energy-saving vortex composite road sweeper. Background Technology

[0002] With the acceleration of urbanization, the demand for urban road cleaning is constantly increasing. Traditional road sweepers have many problems in the cleaning process, such as incomplete garbage collection. These problems not only affect urban environmental sanitation but also cause pollution.

[0003] Existing sweeper truck storage bins typically employ a simple open or semi-open structure, which easily leads to waste overflow during collection and storage. Furthermore, the strong airflow from the sweeper truck's blower outlet blows directly from the top of the storage bin, utilizing only the negative pressure generated by the blower's inlet. This is not only unsafe but also significantly reduces the blower's efficiency. In addition, traditional storage bins lack effective cleaning functions after waste collection, making it difficult to resolve issues of waste residue and odor within the storage bin.

[0004] As a core component of road sweepers, the suction cup performs the functions of garbage collection and sweeping. Its structural design directly determines the sweeping efficiency, environmental adaptability, and operational cleanliness. Currently, most mainstream sweeping equipment suction cups adopt a single-function design, which makes it difficult to meet the needs of efficient sweeping under complex road conditions. Existing technical defects have become a key bottleneck restricting the improvement of sweeping effects.

[0005] Existing cleaning equipment generally relies on a "roller brush sweeping combined with single airflow suction" operation mode, without establishing a collaborative mechanism for active guidance and precise aggregation. This means that for fine dust and lightweight, scattered debris on the road surface, the lack of directional external force guidance and passive sweeping by the roller brush easily leads to debris being dispersed by the airflow or remaining in road surface crevices, making thorough removal impossible. Furthermore, the lack of a targeted aggregation structure during debris collection allows large debris and long, strip-shaped waste such as branches and plastic ropes to accumulate around the suction port, reducing the suction efficiency of the air duct and potentially causing blockages, requiring frequent shutdowns for cleaning and severely impacting operational continuity.

[0006] Meanwhile, insufficient sealing between the suction cups and the ground, as well as inadequate airflow control, leads to significant dust generation during operation. Most suction cups only have a partial rubber seal on the upper side of the roller brush, while the circumferential area where the suction cup contacts the ground lacks a complete seal. This allows suction airflow to easily leak out through the gaps, weakening the suction power and causing dust to spread into the surrounding environment, resulting in secondary pollution and failing to meet environmental protection requirements. Furthermore, while some suction cups have simple baffles, the fit between the baffles and the ground is inadequate for uneven surfaces, allowing debris to escape from the edges and further reducing cleaning effectiveness.

[0007] Regarding the adjustment of roller brush height and its adaptability to road conditions, existing technologies suffer from low adjustment precision and insufficient flexibility. The existing adjustment method involves a telescopic cylinder driving the roller brush to rotate around a fixed axis to achieve height adjustment. While this can prevent the roller brush from tilting, the adjustment process relies on the synchronous action of the telescopic mechanism, making it difficult to accurately control the roller brush's contact pressure based on real-time working conditions such as road bumps and potholes. Furthermore, the connection between the roller brush and the suction cup 7 body is fixed, making it impossible to adaptively fine-tune according to the flatness of the ground. This results in some areas of the brush bristles being too loose (missed areas) or too tight (excessive wear) when working on uneven roads, affecting both cleaning quality and shortening the roller brush's lifespan.

[0008] In addition, there are obvious shortcomings in the adaptability and ease of maintenance of the garbage collection structure. Most of the existing suction cups adopt a single suction port design, which limits the range of garbage accumulation when facing wide cleaning scenarios, and it is easy to miss some areas. Moreover, there is no auxiliary cleaning structure for the suction port, so fibers, hair and other debris that get tangled in the roller brush cannot be scraped off in time. Long-term accumulation will hinder the rotation of the roller brush and reduce cleaning efficiency. Utility Model Content

[0055] The working principle of this utility model is as follows:

[0056] The sweeper moves forward, starts the engine 18 and blower 17, adjusts the water spray frame 2 to the appropriate height and opens it, sprays water to pre-wet the garbage on the road surface to prevent the sweeper from carrying garbage away at high speed. The side brush assembly 4 sweeps the garbage on the ground on both sides of the sweeper into the bottom of the vehicle, and the anti-splash assembly 5 blocks the garbage from splashing and helps to concentrate the garbage for the next step of collection.

[0057] The first flexible garbage baffle 7-22, the third flexible garbage baffle 7-23, and the fourth flexible garbage baffle 7-20 in the suction area of ​​the suction cup 7 gather the garbage on the road surface in front to the lower end of the second trapezoidal pipe 7-3-3 of the garbage suction pipe. Because the blower 17 draws air from the garbage collection chamber through the first ventilation pipe 16 and blows it into the air storage chamber 19, a negative pressure environment is created in the garbage collection chamber, which in turn draws the garbage on the road surface into the garbage collection chamber. The airflow blown out by the blower 17 enters the suction cup 7 through the air storage chamber 19 and the second ventilation pipe 9. In the blowing zone, the radial guide plate effectively blows dust and garbage towards the suction and sweeping zone, realizing the recycling of airflow from the blower 17. The rotating roller brush in the suction and sweeping zone sweeps the remaining garbage towards the lower port of the garbage suction pipe. The second flexible garbage baffle 7-21, the third flexible garbage baffle 7-23, and the fifth flexible garbage baffle 7-24 gather the garbage directly below the lower port of the second trapezoidal tube 7-3-3 of the garbage suction pipe, so that the garbage is sucked into the garbage recycling chamber for storage. After the garbage is dumped, the nozzle of the cleaning structure 13 sprays water to clean the garbage recycling chamber.
