Description

Technical Field

[0001] This utility model belongs to the technical field of road sweeping equipment, specifically relating to a component of a sweeping equipment. Background Technology

[0002] In the field of road sweeping equipment technology, the suction cup, as the core component for garbage collection and sweeping, directly determines the sweeping efficiency, environmental adaptability, and operational cleanliness through its structural design. Currently, most mainstream sweeping equipment suction cups adopt a single-function design, which is insufficient to meet the high-efficiency sweeping needs under complex road conditions. Existing technological deficiencies have become a key bottleneck restricting the improvement of sweeping effectiveness.

[0003] 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.

[0004] 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.

[0005] Regarding the adjustment of roller brush height and its adaptability to road conditions, existing technologies suffer from low adjustment precision and insufficient flexibility. Current adjustment methods involve a telescopic cylinder driving the roller brush to rotate around a fixed axis to achieve height adjustment. While this prevents the roller brush from tilting, the adjustment process relies on the synchronous movement of the telescopic mechanism, making it difficult to accurately control the roller brush's contact pressure based on real-time road conditions such as bumps and potholes. Furthermore, the fixed connection between the roller brush and the suction cup body prevents adaptive fine-tuning based on ground flatness. This results in some areas of the brush bristles being too loose (missed areas) or too tight (excessive bristle wear) when working on uneven surfaces, affecting both cleaning quality and shortening the roller brush's lifespan.

[0006] Furthermore, the adaptability and ease of maintenance of the waste collection structure also have significant shortcomings. Existing suction cups mostly use a single suction port design, which limits the area of ​​waste accumulation in wide-area cleaning scenarios, easily leading to missed areas. Moreover, the suction port lacks auxiliary cleaning structures, meaning that fibers, hair, and other debris entangled during roller brush operation cannot be scraped off in time, and long-term accumulation will hinder roller brush rotation, reducing cleaning efficiency. At the same time, roller brush maintenance requires disassembling the suction cup body or related components, which is cumbersome and costly, further restricting the long-term operational stability of the equipment.

Two universal wheels 9 are installed on the outer sides of each of the two long side plates of the mounting frame 1 to assist in walking and provide support for the mounting frame 1.

[0033] The drive mechanism of this embodiment includes a hydraulic motor 10, a drive sprocket 11, a chain 12, a driven sprocket 14, and a tension wheel 13.

By rotating the screw through the handle 15-5, the nut 15-2 drives the height adjustment plate 15-1 to move up or down along the guide groove, thereby causing the roller brush assembly 19 to move up or down with the height adjustment plate 15-1.

[0035] exist Figures 7-9 In this embodiment, the suction pipe 6 is composed of a circular pipe 6-1, a first trapezoidal pipe 6-2, and a second trapezoidal pipe 6-3 connected from top to bottom. The circular pipe 6-1 is used to connect to the garbage collection system of the cleaning equipment. A roller brush scraper 6-4 is provided on the lower end of the second trapezoidal pipe 6-3 near the roller brush assembly 19. The roller brush scraper 6-4 is used to scrape the garbage on the roller brush onto the ground.

[0036] The waste collection baffle assembly of this embodiment includes a first flexible waste baffle 22, a second flexible waste baffle 21, a third flexible waste baffle 23, a fourth flexible waste baffle 20, and a fifth flexible waste baffle 24. The first flexible waste baffle 22, the second flexible waste baffle 21, the third flexible waste baffle 23, the fourth flexible waste baffle 20, and the fifth flexible waste baffle 24 are vertically arranged on the top plate 2, and their lower ends are retracted a certain distance relative to the first flexible baffle 8, so that during the cleaning process, the distance from the lower end of the first flexible waste baffle to the ground is greater than the distance from the lower end of the first flexible baffle 8 to the ground. The third flexible waste baffle 23 is parallel to the long side plate of the mounting frame 1 and also parallel to the lower end of the second trapezoidal pipe 6-3 of the suction pipe 6. One end of the third flexible waste baffle 23 is connected to one end of the first flexible waste baffle 22 and the second flexible waste baffle 21 to form a Y-shaped structure, and the other end of the third flexible waste baffle 23 is connected to one end of the fourth flexible waste baffle 20 and the fifth flexible waste baffle 24 to form a Y-shaped structure. The second flexible garbage baffle 21, the third flexible garbage baffle 23, and the fifth flexible garbage baffle 24 are used to collect garbage swept by the roller brush assembly 19, so that the garbage is concentrated directly below the lower port of the second trapezoidal pipe 6-3 of the suction pipe 6. The first flexible garbage baffle 22, the third flexible garbage baffle 23, and the fourth flexible garbage baffle 20 are used to collect garbage on the front side of the road, so that the garbage is concentrated directly below the lower port of the second trapezoidal pipe 6-3 of the suction pipe 6, so that the garbage can be sucked into the suction pipe 6 and output through the suction pipe 6.

[0037] The working principle of this utility model is as follows: When the cleaning equipment starts, during cleaning, the air source delivers airflow to the blowing area through the blower pipe 4. Radial guide plates 17 are installed in the blowing area, which evenly guide the airflow towards the suction area. Under the action of the guide plates, the airflow blows dust and debris towards the suction area. The roller brush assembly 19 in the suction area is driven by a hydraulic motor 10, which transmits power through the drive sprocket 11, chain 12, and driven sprocket 14, causing the roller brush to rotate at high speed. During rotation, the roller brush sweeps the debris and dust from the ground into the suction area, where it is surrounded by the debris collection baffle assembly. In the area formed, the second flexible garbage baffle 21, the third flexible garbage baffle 23, and the fifth flexible garbage baffle 24 collect the garbage swept by the roller brush assembly 19 and bring it directly below the lower port of the second trapezoidal pipe 6-3 of the suction pipe 6. At the same time, as the sweeping equipment moves forward, the first flexible garbage baffle 22, the third flexible garbage baffle 23, and the fourth flexible garbage baffle 20 are used to collect the garbage on the road surface in front and bring it directly below the lower port of the second trapezoidal pipe 6-3 of the suction pipe 6. The suction pipe 6 absorbs the collected garbage into the garbage collection system of the sweeping equipment.
