[0002] Road sweepers are suitable for cleaning dry roads in all climates and on all types of surfaces, efficiently cleaning asphalt, concrete, and gravel surfaces. Their primary functions include sweeping the ground, cleaning curbs, and applying water afterward. Not only are these vehicles suitable for all weather conditions, they also effectively remove debris and dirt from the roads, keeping them tidier and cleaner. Their sweeping brushes easily remove debris such as leaves, paper scraps, cigarette butts, sand, and dust, while also removing oil and chemical residues from the roads, ensuring safe and clean roads.

[0003] For example, in the patent publication number "CN205444058U," "A Highway Garbage Sweeper," the front sweeping device includes a front sweeping brush and its brush fixing and control mechanism. The front sweeping brush is composed of a brush roller and an upper cover. A middle bearing seat and a tail bearing seat with hanging ears are mounted on the bottom edge of the semi-covered upper cover. The brush roller's rotating shaft extends outward from the middle bearing seat, and a driven transmission gear is mounted on the shaft head of the brush roller's rotating shaft.

DETAILED DESCRIPTION

[0020] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] A road sweeper, such as Figures 1-6As shown, it includes a sweeper body 1, a first sweeping brush 2, an electric slide rail 3, a slide column 4, a rotating plate 5, a moving component, a gear set 6, a second sweeping brush 7, a fixed plate 8, a first sliding plate 9, a first dustproof plate 91, a second sliding plate 10, a second dustproof plate 101, a nozzle 19 and a mist injector 20. The first sweeping brush 2 is installed on the front and rear sides of the sweeper body 1. The right side of the sweeper body 1 is rotatably connected to two rotating plates 5. The tops of the rotating plates 5 are each provided with a slide groove 51. The right side of the sweeper body 1 is fixedly connected to the electric slide rail 3, the fixed plate 8 and the moving component. The electric slide rail 3 is located below the fixed plate 8. The slider of the electric slide rail 3 is fixedly connected with a slide column 4. The slide column 4 is slidably connected to the slide groove 51 of the rotating plate 5 on one side. 3 is connected to the bottom of the vehicle body 1, and the two rotating plates 5 are connected by the gear group 6. The second sweeping brush 7 is installed on each rotating plate 5. The first sliding plate 9 and the second sliding plate 10 are slidably connected inside the fixed plate 8. The first sliding plate 9 and the second sliding plate 10 are both connected to the moving component. The first sliding plate 9 is fixedly connected to the first dustproof plate 91 along the circumferential direction, and the second sliding plate 10 is fixedly connected to the second dustproof plate 101 along the circumferential direction. The left sides of the first dustproof plate 91 and the second dustproof plate 101 are aligned with the front wheels of the sweeper body 1. The first sweeping brush 2 and the second sweeping brush 7 are fixedly connected to a nozzle 19. A mist emitter 20 is installed on the top of the sweeper body 1. The nozzle 19 and the mist emitter 20 are both connected to the water supply system in the sweeper body 1.

[0022] When it is necessary to clean the road, the hydraulic motors on the first sweeping brush 2 and the second sweeping brush 7 are used to rotate. During the driving process of the sweeper body 1, the first sweeping brush 2 and the second sweeping brush 7 can be used to clean the road. The first sliding plate 9, the second sliding plate 10, the first dustproof plate 91 and the second dustproof plate 101 form a closed space. The closed space can block the dust generated when the first sweeping brush 2 is sweeping, and the dustproof cover 15 can block the dust generated when the second sweeping brush 7 is sweeping, preventing the dust from floating in the air and causing secondary pollution. When it is necessary to clean the curb, the electric slide rail 3 drives the upper slider to move forward, and the slide column 4 slides in the slide groove 51 The movement causes the front and rear rotating plates 5 to rotate away from each other under the action of the gear set 6, so that the second sweeping brush 7 is close to the curb, thereby being able to clean the curb. When the second sweeping brush 7 needs to be reset, the electric slide rail 3 drives the slider thereon to move in the opposite direction, so that the second sweeping brushes 7 are reset close to each other. The cleaning area of ​​the second sweeping brush 7 can be controlled according to the cleaning needs. The dustproof plate and the dustproof cover 15 are sprayed with water by the nozzle 19, which can reduce dust and keep the ground moist. The fine water mist is sprayed by the mist emitter 20, which can effectively capture and settle dust and fine particles in the air, reduce dust pollution, and improve the air quality in the cleaning operation area.

[0023] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, the moving assembly includes a hydraulic cylinder 11, a rack 12, a transmission gear 13 and a protective cover 14. The protective cover 14 is fixedly connected to the right side of the sweeper body 1, and the hydraulic cylinder 11 is installed in the protective cover 14. The hydraulic cylinder 11 is fixedly connected to the second sliding plate 10, and the transmission gear 13 is rotatably connected in the protective cover 14. The first sliding plate 9 and the second sliding plate 10 are both fixedly connected with a rack 12, and the rack 12 is engaged with the transmission gear 13. The hydraulic cylinder 11, rack 12 and transmission gear 13 are all inside the protective cover 14. The protective cover 14 can protect the hydraulic cylinder 11, rack 12 and transmission gear 13. Through grooves for the rack 12 to move are opened on the front and back sides of the protective cover 14.

[0024] like Figure 1 and Figure 6 As shown, it also includes a dust cover 15, a connecting pipe 16, a turning handle 17 and a cleaning brush 18. The dust cover 15 is connected to the front and rear sides of the sweeper body 1, and the first sweeping brush 2 is located in the dust cover 15. The dust cover 15 is connected with a connecting pipe 16, which passes through the outer wall of the dust cover 15. The outer wall of the dust cover 15 is rotatably connected to the turning handle 17. The turning handle 17 is divided into a grip and a rotating shaft. The grip is hingedly connected to the turning handle 17, and the turning handle 17 is fixedly connected to the rotating shaft. The rotating shaft is rotatably connected to the dust cover 15, and the rotating shaft on the turning handle 17 passes through the outer wall of the dust cover 15. A cleaning brush 18 adapted to the inner wall of the dust cover 15 is fixedly connected to the rotating shaft of the turning handle 17, and the cleaning brush 18 contacts the inner wall of the dust cover 15.

[0025] After the cleaning operation is completed, when it is necessary to clean the dust cover 15, the water spray end of the water gun is inserted into the connecting pipe 16 to spray water to clean the inside of the dust cover 15, and the turning handle 17 is turned to drive the cleaning brush to clean the inner wall of the dust cover 15. Under the cooperation of the water gun and the cleaning brush, the dust cover 15 can be kept clean and tidy. When it is necessary to clean the dust plate, the hydraulic cylinder 11 drives the second sliding plate 10 to slide away from the first sliding plate 9, and the second sliding plate 10 drives the rack 12 thereon to move away from the transmission gear 13. Under the meshing action of the transmission gear 13 and the rack 12, the rack 12 on the second sliding plate 10 drives the transmission gear 13 to rotate, and the rotation of the transmission gear 13 causes the first sliding plate 9 to move away from the first sliding plate 9. The rack 12 on 9 moves away from the second sliding plate 10, so that the first sliding plate 9 and the second sliding plate 10 slide away from each other. At this time, the first sliding plate 9 and the second sliding plate 10 are both away from the sweeper body 1, so that a water gun can be used to clean the inside of the first sliding plate 9 and the second sliding plate 10, and then the dustproof plate can be cleaned with a water gun, thereby improving the service life of the dustproof cover 15 and the dustproof plate. After the dustproof plate is cleaned, the second sliding plate 10 is driven by the hydraulic cylinder 11 to slide close to the first sliding plate 9. Under the meshing action of the transmission gear 13 and the rack 12, the first sliding plate 9 slides close to the second sliding plate 10, so that the first sliding plate 9 and the second sliding plate 10 can be reset.

[0026] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
