Description

Technical Field

[0001] This utility model relates to a dust suppression device and vehicle for a high-speed sweeper, belonging to the field of sweeper technology. Background Technology

[0002] During operation, the strong centrifugal force generated by the high-speed rotation of the roller brush in traditional high-speed sweepers causes some dust to detach from the sweeping path. Dust that is not collected by the elevator in time is easily splashed onto the elevator casing and surrounding areas, creating large-scale secondary dust pollution. While existing technologies attempt to intercept dust by installing fixed baffles behind the roller brush, unavoidable gaps exist at the junction of the baffle, roller brush, and elevator. Furthermore, the baffle angle cannot be adapted to the dust splash trajectory, allowing dust to still escape from the joint between the roller brush and elevator. This not only reduces dust collection efficiency but also pollutes the working environment, severely impacting the overall cleaning performance of the sweeping equipment. Summary of the Invention

[0003] To address the problems existing in the prior art, this utility model provides a dust suppression device and vehicle for high-speed sweepers, which is compatible with the upgrading and transformation of existing sweepers, achieving efficient dust suppression and improved cleaning efficiency while maintaining equipment compatibility.

[0004] To achieve the above objectives, this utility model employs a dust suppression device for a high-speed sweeper, comprising: The elevator has an internal chain-driven scraper conveyor mechanism and an external elevator casing. A roller brush, comprising a brush body and a roller brush housing mounted on the upper part of the brush body; The dust suppression structure includes a dust baffle and a dust guide plate located below the dust baffle. The dust baffle is installed at the joint gap between the elevator housing and the roller brush housing. The lower end of the dust baffle extends to the edge area of ​​the dust sweeping trajectory of the brush body and is fixedly connected to the roller brush housing. The upper end is fixedly installed on the elevator housing, forming a physical barrier to prevent dust from splashing. The dust guide plate is a downwardly inclined bent structure, set on the upper edge of the dust inlet of the elevator. Its upper end extends inclinedly towards the elevator, and its lower end is suspended above the scraper running trajectory of the scraper conveying mechanism to guide dust into the scraper's effective range.

[0005] As an improvement, the dust baffle is a one-piece molded Z-shaped structure, including an upper baffle, a middle baffle, and a lower baffle that are bent and connected in sequence.

[0006] As an improvement, the upper baffle is arranged parallel to the horizontal plane, one side of which is detachably installed on the hoist housing, and the other side is bent at a preset angle to transition with the middle baffle; the end of the middle baffle away from the upper baffle is bent and connected to the lower baffle, the lower baffle is detachably installed on the roller brush housing, and the overall coverage of the dust baffle covers the joint gap between the hoist housing and the roller brush housing.

[0007] As an improvement, the dust baffle is connected to the elevator housing and the roller brush housing by bolts.

[0008] As an improvement, the dust guide plate includes an upper guide plate and a lower guide plate formed by integral bending; the upper guide plate is provided with a plurality of elongated holes spaced apart along its length, and fixing bolts pass through the elongated holes to fix the upper guide plate to the hoist housing.

[0009] As an improvement, the length direction of the elongated hole is adapted to the flow direction of the dust guide plate, which allows for fine adjustment of the installation position of the upper guide plate.

[0010] As an improvement, the bending angle between the upper guide plate and the lower guide plate is 125°-145°, and the lower guide plate is arranged at an acute angle to the horizontal plane.

[0011] As an improvement, the distance between the lower edge of the lower guide plate and the tip of the brush body is 3-5cm, and the lateral coverage of the lower guide plate covers the joint gap between the roller brush and the elevator, so that dust is guided along the inclined surface of the lower guide plate into the scraper action range of the elevator.

[0012] As an improvement, the dust guide plate is made of wear-resistant steel plate.

[0013] In a second aspect, this utility model also provides a vehicle equipped with the aforementioned high-speed sweeper dust suppression device, wherein the vehicle is a high-speed sweeper.

[0014] Compared with the prior art, the dust suppression device for high-speed sweepers of this utility model has the following beneficial effects: 1. Significant synergistic dust suppression effect. Through the coordinated structure of the dust baffle and dust guide plate, the dust baffle accurately intercepts the splashing dust generated by the high-speed rotation of the roller brush, while the dust guide plate directionally guides the falling dust into the effective range of the lifting scraper, forming a closed-loop dust suppression path of interception and diversion. This significantly reduces secondary dust and dust escape from traditional sweepers, improving the cleanliness of road cleaning.

[0015] 2. Strong structural design adaptability. The dust baffle is installed at the joint gap between the elevator and the roller brush, and extends to the edge of the brush sweeping trajectory. The dust guide plate is arranged to fit the dust inlet of the elevator. The overall structure does not require modification of the core components of the sweeper's main unit, and can be directly adapted to the upgrade and transformation of existing high-speed sweepers, with high compatibility and low transformation cost.

[0016] 3. Stable and durable operation. The dust baffle forms a solid physical barrier through fixed connection, and the dust guide plate adopts a bent structure design. Both are reliably assembled with the equipment shell. Under the condition of high-speed operation of the roller brush, it can withstand the impact and vibration of dust, and has strong structural stability. Moreover, it does not require additional power drive, and relies on mechanical structure to achieve dust suppression, reducing energy consumption and failure risk, and has a long service life.

[0017] 4. Improved cleaning efficiency. The lower end of the dust guide plate is suspended above the scraper's running path, which can guide the dust directly into the scraper's effective range, reducing the accumulation and retention of dust inside the equipment and ensuring the conveying efficiency of the elevator; at the same time, the dust baffle plate prevents dust from splashing to the outside of the equipment or dead corners, reducing subsequent secondary cleaning work and improving the continuity and efficiency of the overall cleaning operation.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this application will be described in detail below through specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0021] like Figures 1-5 As shown, a dust suppression device for a high-speed sweeper includes a lift 3, a roller brush 4, and a dust suppression structure installed between the lift 3 and the roller brush 4. The device achieves efficient dust suppression through the coordinated design of upper baffle and lower guide. The elevator 3 is equipped with a chain-driven scraper conveying mechanism inside and an elevator shell on the outside, providing a stable carrier for dust conveying; The roller brush 4 includes a brush body and a roller brush shell 4-1 installed on the upper end of the brush body to ensure the structural stability of the roller brush during high-speed cleaning. The dust suppression structure includes a dust baffle plate 1 and a dust guide plate 2 located below the dust baffle plate 1, which together form a three-dimensional dust suppression protection: the dust baffle plate 1 is installed at the joint gap between the elevator shell and the roller brush shell 4-1, with its lower end extending to the edge area of ​​the dust sweeping trajectory of the brush body and fixedly connected to the roller brush shell 4-1, and its upper end fixed to the elevator shell, forming a physical barrier that blocks dust splashing without dead angles, and can directly intercept the dust thrown by the centrifugal force generated by the high-speed rotation of the roller brush; the dust guide plate 2 is a downwardly inclined bent structure, adapted to the upper edge of the dust inlet of the elevator 3, with its upper end extending inclinedly into the elevator 3 and its lower end suspended above the scraper running trajectory of the scraper conveying mechanism, which can guide the dust that falls back after being intercepted by the dust baffle plate and the scattered dust to the range of action of the scraper, avoiding secondary dust.

[0022] In some embodiments, such as Figure 2 As shown, the dust baffle 1 is an integrally formed Z-shaped structure, including an upper baffle 1-1, a middle baffle 1-2 and a lower baffle 1-3 connected by bending in sequence. Its integral design not only improves the overall strength and impact resistance of the structure, but also precisely adapts the Z-shaped contour to the joint gap between the hoist housing and the roller brush housing 4-1, ensuring that there are no blind spots in the shielding.

[0023] In some embodiments, the upper baffle 1-1 is arranged parallel to the horizontal plane, with one side detachably installed on the hoist housing for easy maintenance and replacement; the other side is bent at a preset angle of 90°-120° to the middle baffle 1-2 to adapt to the installation layout of the hoist and the roller brush; the end of the middle baffle 1-2 opposite to the upper baffle 1-1 is bent and connected to the lower baffle 1-3 to ensure the integrity and impact resistance of the Z-shaped structure; the lower baffle 1-3 is also detachably installed on the roller brush housing 4-1, and the entire coverage of the dust baffle 1 completely covers the seam gap between the hoist housing and the roller brush housing 4-1, preventing dust from leaking from the gap and further enhancing the dust suppression effect of the physical barrier.

[0024] In some embodiments, the dust baffle 1 is detachably and fixedly connected to the elevator housing and the roller brush housing 4-1 by bolts. This connection is not only stable and able to withstand the dust impact and vibration when the roller brush is running at high speed, but also has the advantage of easy disassembly and assembly, which facilitates later maintenance, replacement or repair.

[0025] In some embodiments, as shown in Figures 3 and 4, the dust guide plate 2 adopts an integral bending structure, which is formed by bending the upper guide plate 2-1 and the lower guide plate 2-2 continuously. This ensures both the integrity of the structure and its resistance to deformation, while also accurately matching the flow guiding angle requirements. The upper guide plate 2-1 has multiple elongated holes 2-3 evenly spaced along its length. Fixing bolts pass through the elongated holes 2-3 to securely mount the upper guide plate 2-1 to the hoist housing. The design of the elongated holes 2-3 provides space for adjusting the installation position of the dust guide plate 2, adapting to the gap adaptation requirements under different working conditions.

[0026] In some embodiments, the length direction of the elongated hole 2-3 is precisely matched with the flow direction of the dust guide plate 2. The stroke margin of the elongated hole 2-3 allows for fine adjustment of the installation position of the upper guide plate 2-1 along the flow direction, thereby precisely matching the different connection gaps between the roller brush 4 and the elevator 3. This ensures that the lower edge of the dust guide plate 2 always maintains the optimal distance from the tip of the brush body, guaranteeing the stability and reliability of the directional flow of dust.

[0027] In some embodiments, the bending angle between the upper guide plate 2-1 and the lower guide plate 2-2 is designed to be 125°-145°, and the lower guide plate 2-2 is arranged at an acute angle to the horizontal plane. This combination of angles ensures that the lower guide plate 2-2 has sufficient guiding slope, allowing dust to slide smoothly under gravity and avoid accumulation. It also adapts to the installation space of the dust inlet of the elevator 3 and the cleaning trajectory of the roller brush 4, so that the guiding path and the receiving range of the scraper conveying mechanism are precisely matched, thereby improving the dust introduction efficiency.

[0028] In some embodiments, the distance between the lower edge of the lower guide plate 2-2 and the tip of the brush body is precisely controlled to be 3-5cm. This distance avoids interference with the high-speed rotating brush body and maximizes the capture of scattered dust at the edge of the sweeping trajectory. At the same time, the lateral coverage of the lower guide plate 2-2 completely covers the gap between the roller brush 4 and the elevator 3, preventing dust from escaping from the gap. Combined with its inclined bending structure, the captured dust can be directed along the surface to the scraper action range of the elevator 3, ensuring efficient dust collection and no secondary dust generation.

[0029] In some embodiments, the dust guide plate 2 is made of Q355B wear-resistant steel plate. This material belongs to low-alloy high-strength wear-resistant steel, which has both excellent wear resistance and structural strength. The yield strength can reach 355MPa. Compared with ordinary carbon steel, its wear resistance is significantly improved. It can effectively resist long-term impact and friction of dust and scraping of sand and gravel particles that may be encountered during sweeping operations. It is suitable for the high-frequency operation needs of high-speed sweepers in dusty conditions such as urban roads, construction sites, and gravel roads, and greatly extends the service life of the dust guide plate 2. The dust baffle plate 1 is made of Q235A steel. This material has reliable structural strength and good bending processing adaptability. It can withstand the dust impact and equipment vibration when the roller brush is running at high speed, ensuring the stability of the physical barrier. It can also accurately meet the processing requirements of Z-shaped integrated bending and forming. At the same time, it takes into account material cost and practical performance, and has an outstanding cost performance.

[0030] Finally, as Figure 1 , Figure 5 As shown, in a second aspect, this utility model also provides a high-speed sweeper, which is equipped with the dust suppression device for high-speed sweepers described in any of the above embodiments. The dust suppression device's elevator 3 and roller brush 4 are precisely matched with the sweeper's power system and sweeping operation system. It can simultaneously achieve closed-loop dust suppression, including dust interception, directional flow guidance, and efficient collection, during the sweeper's high-speed operation. This effectively reduces secondary dust pollution during road sweeping, improves the cleanliness and environmental friendliness of the sweeping operation, and the device has a compact structure and strong adaptability. It does not require major modifications to the sweeper's main unit, thus balancing practicality and ease of installation.

[0031] The dust suppression device for high-speed sweepers of this utility model has the following technical advantages: 1. High dust suppression efficiency and outstanding environmental protection: Through the coordinated design of dust baffles and dust guides, a closed-loop dust suppression system is constructed. This system can not only block the splashing dust generated by the high-speed rotation of the roller brush, but also guide the scattered dust into the elevator for efficient collection. This eliminates secondary dust and gap leakage from the source, greatly improves the cleanliness of road sweeping, and reduces environmental pollution.

[0032] 2. Scientific structural design and stable and reliable operation: The Z-shaped integrated structure of the dust baffle and the bending structure of the dust guide plate both have high strength and resistance to impact and deformation; key parameters (such as 125°-145° bending angle and 3-5cm spacing) are precisely adapted to working conditions, and the elongated hole micro-adjustment design can cope with different connection gaps, ensuring that the device is free from interference and failure in high-frequency operation and has a long service life.

[0033] 3. High adaptability and convenient installation and maintenance: The device has a compact overall structure and can be assembled without modifying the main unit of the sweeper, making it compatible with the upgrade needs of existing high-speed sweepers; the dust baffle is connected by bolts, and the material selection of the dust guide plate and dust baffle takes into account both machinability and maintainability, making it efficient and convenient for disassembly, replacement or maintenance in the later stage.

[0034] 4. Excellent cost performance and wide range of applications: The dust baffle is made of Q235A steel and the dust guide plate is made of Q355B wear-resistant steel plate. The materials are suitable for functional requirements and the cost is controllable. The device can easily cope with dusty working conditions such as urban roads, construction sites, and gravel roads. It not only meets the wear resistance and impact resistance requirements of high-frequency operations, but also takes into account economy and has a wide range of application prospects.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
