[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. Furthermore, features described for some examples may be combined in other examples.

[0020] Example 1: The invention provides Figures 1 to 7 As shown, a dry sweeper includes: A dust removal box 19 and a movable frame 11, the dust removal box 19 is installed on the frame 11, a suction port 111 is provided at the bottom of the dust removal box 19, and a suction structure 113 is provided in the dust removal box 19, and the suction structure 113 sucks debris into the interior of the dust removal box 19 through the suction port 111; A transmission chain 24 is installed around the suction port 111 of the dust removal box 19, and the transmission chain 24 is driven to rotate at the suction port 111. Scrapers 25 are installed on the links of the transmission chain 24. The transmission chain 24 drives the scrapers 25 to scrape and clean the edge of the suction port 111 to prevent the accumulation and adhesion of debris at the suction port 111 from affecting the continuous suction and collection of debris.

[0021] Working Principle: The suction structure 113 in the dust box 19 of the present invention generates negative pressure through the bottom suction port 111, continuously sucking in debris on the ground to realize the suction mechanism. The anti-blocking cleaning mechanism is driven by the transmission chain 24 around the suction port 111, which drives the scraper 25 on the chain link to dynamically scrape the edge of the suction port 111, removing potential accumulations in real time. The dry sweeper of the present application has a good suction effect for removing waste from roads or similar roads, whether spraying or not spraying. Anti-clogging protection: The continuous scraping action of the scraper 25 effectively prevents debris from adhering to and accumulating on the edge of the suction port 111, ensuring a stable and uninterrupted debris suction process and improving cleaning reliability. Suction efficiency is optimized, and the cleaning mechanism directly acts on key blockage points, reducing the need for maintenance interruptions and maintaining efficient debris collection performance.

[0022] like Figures 3 to 5 As shown, a mounting groove 23 is installed at the suction port 111, and a transmission chain 24 is rotatably installed inside the mounting groove 23. Scrapers 25 on the transmission chain 24 clean the surface of the mounting groove 23. Scrapers 25 are installed on the upper and lower parts of the chain links of the transmission chain 24. Two sets of scrapers 25 clean the inner and outer parts of the mounting groove 23 respectively.

[0023] A plurality of supporting sprockets 211 and driving sprockets 212 are installed inside the installation groove 23 . The supporting sprockets 211 are used to support and install the transmission chain 24 , and the driving sprockets 212 are used to drive the transmission chain 24 .

[0024] like Figure 7 As shown, in order to obtain a better scraping and cleaning effect, the scraping member 25 is provided with a scraping blade head 26 , and the scraping blade head 26 is attached to the surface of the mounting groove 23 .

[0025] The suction structure 113 is configured as a motor-driven exhaust fan, and the motor of the exhaust fan simultaneously drives the drive sprocket 212 to ensure synchronous operation of the suction structure 113 and the scraper 25.

[0026] like Figure 4 As shown, optionally, the drive sprocket 212 can be driven independently. A drive motor 29 is provided on the dust removal box 19, and a rotating shaft 27 is connected to the rotating shaft of the drive sprocket 212. A shaft seat 28 is provided on the dust removal box 19, and the rotating shaft 27 is rotatably installed on the shaft seat 28. The rotating shaft 27 and the output shaft of the drive motor 29 are driven and transmitted through a drive belt 210.

[0027] The bottom of the dust removal box 19 is located on the periphery of the suction port 111 and is equipped with a surrounding scrub brush 21. The surrounding scrub brush 21 partially surrounds the suction area of ​​the suction port 111, so that the suction port 111 can more efficiently suck in debris; the shape of the surrounding scrub brush 21 is set to be trapezoidal and is provided with an opening in the direction of travel of the frame 11. The trapezoidal surrounding makes the suction range of the suction port 111 clearer. At the same time, the surrounding scrub brush 21 will also sweep the dust on the street ground while the frame 11 is moving, so that the dust or debris will be temporarily raised, and the debris can be better sucked in by the suction port 111.

[0028] like Figure 3 and Figure 4 As shown, the surrounding scrub brush 21 is mounted on a scrub brush holder 22 , and the surrounding scrub brush 21 is mounted on the bottom of the dust removal box 19 through the scrub brush holder 22 . The surrounding scrub brush 21 can be replaced by disassembling and assembling the scrub brush holder 22 .

[0029] The frame 11 is equipped with main wheels 17, steering wheels 18 and a driving machine 12. The frame 11 is also equipped with a group of cylindrical brushes 13 and two groups of disc brushes 14. The driving machine 12 is used to simultaneously drive the cylindrical brushes 13 and the disc brushes 14 to operate. The debris cleaned by the disc brushes 14 and the cylindrical brushes 13 is then sucked into the suction port 111.

[0030] like Figure 1 and Figure 2 As shown, a rotating frame 15 is rotatably mounted at the front end of the frame 11. The rotating frame 15 is rotatably mounted on the frame 11. A buffer spring 16 is provided between the rotating frame 15 and the frame 11. Two sets of disc brushes 14 are actually mounted on the rotating frame 15. This allows the two sets of disc brushes 14 to rotate and move within a certain range on the frame 11, and also allows the disc brushes 14 to move along the street shoulder. The specific operation of the cylindrical brush 13 and the disc brush 14 is as follows: the two sets of disc brushes 14 sweep debris from the street inward, and as the frame 11 moves, they are swept by the cylindrical brush 13 and then sucked into the suction port 111.

[0031] The bottom of the dust removal box 19 is provided with a baffle 112, which is attached to the bottom of the cylindrical brush 13. The baffle 112 is used to scrape off the debris adhering to the cylindrical brush 13 and prevent some sticky debris from adhering to the cylindrical brush 13. Specifically, Figure 1 and Figure 2 As shown, a compression push rod 110 is also provided on the dust removal box 19, and a pressure plate is installed at the end of the telescopic rod of the compression push rod 110. The compression push rod 110 drives the pressure plate to compress the debris and garbage inside the dust removal box 19.

[0032] Example 2: Based on Example 1, the present invention also provides a dust removal system, including a dry sweeper.

[0033] In summary, the present invention also has the following comprehensive effects: Dust collection mechanism: The suction port 111 at the bottom of the dust removal box 19 cooperates with the suction structure 113 to generate negative pressure, sucking road debris into the box. Anti-clogging cleaning system: A transmission chain 24 is installed around the suction port 111. The scrapers 25 on the chain links rotate with the chain, continuously scraping the edge of the suction port 111 and the surface of the mounting groove 23 to prevent debris from adhering and accumulating and affecting the suction efficiency. Double scraping design: Scrapers 25 are provided on the upper and lower parts of the chain links to simultaneously clean the inside and outside of the mounting groove 23. Auxiliary cleaning mechanism: Disc brushes 14: Two groups are installed on the elastic rotating frame 15, and they adapt to the road shoulder with the buffer spring 16 to sweep debris inward. Cylindrical brush 13: Receives debris swept in by the disc brush 14 and further sweeps it towards the suction port 111. Baffle 112: Fits against the bottom of the cylindrical brush 13 to scrape off adhering debris and avoid entanglement. Surrounding scrub brush 21: A trapezoidal design surrounds the suction port 111, with a forward opening to guide debris. The bristles lift dust and debris as they move, improving suction efficiency. Drive linkage: The exhaust fan motor synchronously drives the drive chain 24, achieving integrated energy savings. An independent drive motor 29 drives the chain 24 via a drive belt 210, providing high flexibility.

[0034] Efficient anti-blocking: The dynamic cleaning mechanism of the transmission chain 24 and the scraper 25 completely solves the problem of debris adhesion and clogging of the suction port 111, ensuring continuous and stable dust collection. Coordinated optimization of cleaning and suction: The disc brush 14 cleans along the edge with elasticity, the cylindrical brush 13 collects dust for the second time, the surrounding scrub brush 21 assists in dust removal, and negative pressure concentrates suction to form an efficient recycling closed loop. Improved adaptability: The rotating frame 15 and the buffer spring 16 enable the disc brush 14 to adapt to uneven road surfaces and shoulder contours, expanding the effective operating range. Convenient maintenance: The surrounding scrub brush 21 can be quickly disassembled and replaced through the scrub brush holder 22; the comprehensive cleaning of the installation slot 23 by the scraper 25 reduces the frequency of manual cleaning. Multifunctional compatibility: It can operate effectively on both dry and wet roads, without relying on water spraying to suppress dust, and the dust removal box 19 has a built-in compression push rod 110 to compact garbage and increase capacity.

[0035] The above describes the embodiments of the present invention, but the present invention is not limited to the above specific implementation methods. The above specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms under the guidance of the present invention, all of which are protected by the present invention.
