[0045] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Embodiment 1

[0047] See also Figure 1 and Figure 2 The present invention provides a technical solution: a sanitation cleaning sweeper, comprising a slewing bearing 6, the slewing bearing 6 is an internal tooth type, that is, gear teeth are arranged on the inner ring of the slewing bearing 6; a fixed ring plate 4 is fixedly connected to the top of the outer ring of the slewing bearing 6, and the fixed ring plate 4 is used to be installed on the sanitation vehicle; the bottom of the inner ring of the slewing bearing 6 is fixedly connected to the supporting ring 1; the fixed ring plate 4 is coaxial with the outer ring of the slewing bearing 6, and the supporting ring 1 is coaxial with the inner ring of the slewing bearing 6. Since the inner and outer rings of the slewing bearing 6 are coaxial, the fixed ring plate 4 is coaxial with the supporting ring 1.

[0048] A plurality of first cleaning brushes 2 are arranged at the bottom of the support ring 1. The plurality of first cleaning brushes 2 are evenly distributed along the circumference of the axis of the support ring 1, and each first cleaning brush 2 is arranged tilted outward. The material of the first cleaning brush 2 can be nylon, polyethylene or the like.

[0049] See also Figure 3 A rotating ball head 3 is arranged below the supporting ring 1, and all the first cleaning brushes 2 are covered on the outside of the rotating ball head 3; a rotating assembly 5 is arranged on the fixed ring plate 4, and the rotating assembly 5 drives the supporting ring 1 and the rotating ball head 3 to rotate at the same time. The supporting ring 1 and the rotating ball head 3 rotate asynchronously, and the supporting ring 1 rotates around its own axis, and the rotating ball head 3 also rotates around its own axis.

[0050] See also Figure 3-Figure 7The rotating ball head 3 is composed of an umbrella-shaped portion 31 and a hemispherical portion 32 which are coaxially arranged. The hemispherical portion 32 is a hollow structure, and the hemispherical portion 32 and the umbrella-shaped portion 31 are an integrally formed structure. The rotating assembly 5 includes a support frame 51, and the support frame 51 is fixedly arranged on the top of the fixed ring plate 4. A driving motor 52 is installed on the support frame 51, and the output end of the driving motor 52 is connected to a rotating shaft 53, and the top end of the rotating shaft 53 is movably connected to the support frame 51 through a bearing. The bottom end of the rotating shaft 53 is fixedly connected to the umbrella-shaped portion 31, and the rotating shaft 53 is coaxial with the umbrella-shaped portion 31. By driving the rotating shaft 53 to rotate by the driving motor 52, the rotating ball head 3 can be driven to rotate around its own axis.

[0051] A connecting rod 56 is fixedly connected to the support frame 51, and the connecting rod 56 is L-shaped. The vertical part of the connecting rod 56 is located between the gear 54 and the inner ring of the slewing bearing 6, and the horizontal part of the connecting rod 56 is located between the umbrella-shaped part 31 and the gear 54. The horizontal part of the connecting rod 56 is fixedly connected to a mounting ring 55, and the mounting ring 55 is located outside the rotating shaft 53. A bearing is connected between the rotating shaft 53 and the mounting ring 55. By providing the mounting ring 55, the stability of the rotation of the rotating shaft 53 is improved.

[0052] At the same time, the rotating assembly 5 also includes a gear 54, which is sleeved on the outside of the rotating shaft 53 and fixedly connected to the rotating shaft 53; the gear 54 is located inside the slewing bearing 6, and the gear 54 is meshed with the inner ring of the slewing bearing 6; therefore, when the rotating shaft 53 rotates, it can also drive the gear 54 to rotate, and the gear 54 further drives the inner ring of the slewing bearing 6 to rotate, and the rotation speed of the inner ring of the slewing bearing 6 is lower than the rotation speed of the gear 54. Since the support ring 1 is fixedly connected to the inner ring of the slewing bearing 6, the rotation speed of the support ring 1 is lower than the rotation speed of the rotating ball head 3; since the support ring 1 is coaxial with the inner ring of the slewing bearing 6, it is possible to drive the support ring 1 to rotate around its own axis.

[0053] See also Figure 1-Figure 7 , the axes of the umbrella-shaped portion 31 and the hemispherical portion 32 deviate from the axis of the supporting ring 1, as shown in FIG. Figure 3 As shown, some of the first cleaning brushes 2 near the left end of the umbrella-shaped portion 31 do not contact the surface of the rotating ball head 3, and the bottom end of this part of the first cleaning brushes 2 is lower than the bottommost end of the rotating ball head 3; while the remaining first cleaning brushes 2 are in contact with the rotating ball head 3, specifically, the connecting part of the umbrella-shaped portion 31 and the hemispherical portion 32 contacts the remaining first cleaning brushes 2; therefore, compared with the first cleaning brush 2 near the left end of the umbrella-shaped portion 31 (i.e., the first cleaning brush 2 not in contact with the rotating ball head 3), the first cleaning brush 2 in contact with the rotating ball head 3 has an increased outward inclination angle, and the bottom end of the first cleaning brush 2 in contact with the rotating ball head 3 rises upward.

[0054] The supporting ring 1 drives each first cleaning brush 2 to rotate. In the process of any one of the first cleaning brushes 2 being separated from the rotating ball head 3 and being re-contacted with the rotating ball head 3, the bottom end of the first cleaning brush 2 that is separated from the rotating ball head 3 is in contact with the road surface. Since the rotating ball head 3 is provided, the bottom end of the first cleaning brush 2 that is in contact with the rotating ball head 3 is not in contact with the road surface at this time (the bottom end of the first cleaning brush 2 that is in contact with the rotating ball head 3 is higher than the bottom end of the first cleaning brush 2 that is separated from the rotating ball head 3), thereby being able to sweep the garbage or dust on the road surface in the direction close to the rotating axis 53, thereby facilitating the dust suction device of the sanitation vehicle to suck in the garbage or dust; therefore, the above-mentioned sweeping effect can be achieved by horizontally installing the fixed ring plate 4 in a suitable position without adopting the traditional method (i.e., tilting the entire cleaning sweeping disc at a certain angle), thereby facilitating the installation of the entire cleaning sweeping disc.

[0055] At the same time, the rotating ball head 3 continuously rotates around its own axis. When the first cleaning brush 2 can contact with the rotating ball head 3 again after sweeping garbage or dust, the rotating ball head 3 can disturb the first cleaning brush 2, thereby facilitating the debris stuck in the first cleaning brush 2 to be separated from the first cleaning brush 2.

[0056] Embodiment 2

[0057] See also Figure 3 and Figure 8 This embodiment is based on the first embodiment, and a sealing cylinder 7 is fixedly connected to the support frame 51, and the sealing cylinder 7 is coaxial with the fixed ring plate 4; the outer ring surface diameter of the sealing cylinder 7 is equal to the inner ring surface diameter of the fixed ring plate 4, and the bottom end of the sealing cylinder 7 is located inside the fixed ring plate 4; by providing the sealing cylinder 7, it helps to improve the protection of the inner ring of the slewing bearing 6 and the gear 54.

[0058] Embodiment 3

[0059] See also Fig. 9 and Fig.10 This embodiment is based on the second embodiment, and a second cleaning brush 8 is arranged on the hemispherical portion 32. The second cleaning brush 8 includes a main body 81, which is arranged at the lower part of the hemispherical portion 32, and the main body 81 is spirally arranged along the lower surface of the hemispherical portion 32; in addition, the bottom end of the main body 81 extends along a straight line to form an extension portion 82, and the extension portion 82 is used to contact the road surface; the material of the second cleaning brush 8 can be nylon, polyethylene, etc. During the driving of the sanitation vehicle, the rotating main body 81 and the extension portion 82 are convenient for dispersing dust or garbage accumulated on the road surface, thereby facilitating the hanging and sweeping of the first cleaning brush 2, and facilitating the dust suction device of the sanitation vehicle to absorb dust or garbage, thereby improving the cleaning effect of the sanitation vehicle.
