The lower end of the frame 100 is rotatably connected with a wheel axle 120 horizontally arranged along the width direction of the frame 100, two ends of the wheel axle 120 are respectively provided with a wheel 130, in addition, the frame is further provided with a power device 140 connected with one of the transmission shafts 110, the wheel axle 120 is also in transmission connection with the power device 140, and the specific transmission connection structure between the power device 140 and the wheel axle 120 and the transmission shafts 110 is the same as that of a conventional snow sweeping sweeper, which is not the focus of the embodiment, and therefore, the detailed description is omitted here. In addition, the frame 100 is further provided with components such as a handle 150, and the components and the connection structure thereof are also the same as those of the conventional snow sweeper.

Each transmission shaft 110 is fixedly connected with a transmission gear (not shown in the figure), and the two transmission gears are meshed with each other and have the same nominal diameter and tooth number, so that the two transmission shafts 110 rotate in different directions and at the same speed. The lower end of each transmission shaft 110 is fixedly connected with a transmission disc 111, each transmission disc 111 is provided with a snow sweeping brush 200, the snow sweeping brush 200 comprises a brush fixed disc 220 directly or indirectly connected to the transmission disc 111 and a plurality of brush bundles 230 fixedly connected to the brush fixed disc 220, wherein the central axis of the brush fixed disc 230 and the central axis of the corresponding transmission disc 111 are arranged in a staggered manner, namely the brush fixed disc 230 is arranged eccentrically, and when the central axis of one brush fixed disc 230 is positioned on one side of the corresponding transmission disc 111 facing the other transmission disc 111, the central axis of the other brush fixed disc 230 is positioned on one side of the corresponding transmission disc 111 far away from the other transmission disc 111, namely, when one snow sweeping brush 200 rotates until the central axis of the brush fixed disc 230 and the central axis of the corresponding transmission disc 111 are arranged along the width direction of the frame 100, the central axis of each brush fixed disc 230 is positioned on the same side of the corresponding transmission disc 111, the distance between the two brush fixed discs 230 is the same as the distance between the two fixed discs of the two snow sweeping brushes on the conventional double-brush sweeping vehicle, and the distance between the two fixed discs 230 and the central axes of the two snow sweeping brushes 200 is not overlapped, thereby ensuring the actual snow sweeping area, and further ensuring the wiping area of the snow sweeping area.

Considering that the eccentric arrangement of the brush fixing plate 230 may cause centrifugal force during rotation, the centrifugal force may easily cause the vehicle frame 100 to deflect during traveling, and the deflection of the vehicle frame 100 may be slowed to some extent by mounting the wheels 130 on the same wheel axle 120 at both sides of the vehicle frame 100, it is preferable that in the present embodiment, two wheels 130 are mounted at both ends of the wheel axle 120, that is, two wheels 130 are provided at each side of the vehicle frame 100, so as to help further slow the deflection of the vehicle frame 100 and improve the handling performance of the vehicle frame 100.

Preferably, the snow sweeper 200 in this embodiment further includes a connecting plate 210 fixedly connected to the corresponding transmission disc 111, the connecting plate 210 is a circular plate, a plurality of mounting holes 211 connected to the transmission disc 111 are formed in the connecting plate 210, a plurality of arc sliding grooves 212 uniformly distributed around an axis of the connecting plate 210 are formed in an upper end of the connecting plate 210, the arc sliding grooves 212 are sliding grooves in which two opposite side walls are arc surfaces, an arc through hole 213 is formed in a bottom of each arc sliding groove 212, the arc through holes 213 are through holes in which two opposite side walls are arc surfaces, and an arc center point of each arc sliding groove 212 and an arc center point of each arc through hole 213 are located on the axis of the connecting plate 210, that is, a center axis of each arc sliding groove 212 and a center axis of each arc surface corresponding to each arc through hole 213 are coaxially arranged with a center axis of the connecting plate 210.

The sliding blocks 240 are slidably connected in the arc-shaped sliding grooves 212, and elastic expansion members (not shown in the figure) which respectively abut against two ends of the corresponding sliding blocks 240 are arranged in the arc-shaped sliding grooves 212, and the elastic expansion members can be expansion springs or rubber blocks which can push the sliding blocks 240 to reset by using elastic force after being compressed by the sliding blocks 240, so that buffering is realized. The lower end of each sliding block 240 is integrally connected with a supporting column 241 inserted into the corresponding arc-shaped through hole 213, the lower end of each supporting column 241 penetrates out of the corresponding arc-shaped through hole 213, each sliding block 240 is further provided with a through hole 242 coaxially arranged with the supporting column 241, each through hole 242 penetrates through the corresponding supporting column 241 at the same time, and a connecting bolt (not shown in the figure) which is screwed on the brush fixing disk 220 at the same time penetrates through each through hole 42, that is, the brush fixing disk 220 in this embodiment is indirectly connected to the driving disk 111 through the connecting plate 210, and certainly, the brush fixing disk 220 needs to be provided with a threaded hole which is matched with each connecting bolt one to one.
