Description

Technical Field

[0001] The utility model relates to the technical field of snow sweepers, in particular to a hand-push small snow sweeper. Background Art

[0002] At present, it often snows in cold regions, and the accumulation of snow often causes blockages on high-grade highways, urban roads, rural roads, and in front of and behind houses, making it impossible to drive normally, causing many inconveniences to drivers and pedestrians. In order to ensure that the roads are unobstructed, it is necessary to clear the snow in time.

[0003] There are three main ways to remove snow: manual snow removal, chemical solvent snow removal and mechanical snow removal. Manual snow removal generally uses pushing, shoveling and sweeping. Its disadvantages are time-consuming and labor-intensive, low efficiency, and only suitable for small areas. Although chemical solvent snow removal is simple and convenient, the snow melting agent will chemically corrode the road surface, shorten the service life of the road, and also cause serious pollution to the surrounding environment. Mechanical snow removal is currently the most effective snow removal method. It not only has a fast snow removal speed and high snow removal efficiency, but also has a low snow removal cost and will not cause environmental pollution. Therefore, various small snow removal machines with fast snow removal speed and economical price have emerged and have been rapidly promoted and applied.

[0004] At present, snow sweeping equipment is mainly composed of a prime mover, a transmission device, a snow collecting device, a snow removal device, a travel system and an operating device. The snow sweeper sweeps the snow on the road to the roadside or the collection device by reversing the roller brush; the travel system is used to realize the forward and backward movement of the machine, and the manual operation only needs to control the direction of travel to complete the snow sweeping. Although the existing snow sweepers can sweep the snow on the road, it is difficult to guarantee the effect of clearing the frozen ice under the snow.

[0044] The vehicle body 1 is provided with a driving assembly, the two roller brushes 5 are connected to the driving assembly, and the driving wheel 4 is connected to the driving assembly through a transmission structure. When the driving assembly is running, the two roller brushes 5 will rotate in opposite directions, so that the snow on the ground is swept to the two sides of the vehicle body 1. At the same time, the transmission structure will cooperate with the driving assembly to make the driving wheel 4 rotate to push the vehicle body 1 forward.

[0046] In this solution, when the driving component is running, the two roller brushes 5 can rotate in opposite directions, so that the snow on the ground is swept to the two sides of the vehicle body 1. At the same time, the transmission structure will cooperate with the driving component to rotate the driving wheel 4 to push the vehicle body 1 forward.

[0049] In this embodiment, if Figure 4As shown, since the two second gears 9 are meshed with each other, and the second gears 9 are respectively meshed with the two first gears 8, when one of the rotating rods 7 rotates, the first gear 8 and the roller brush 5 fixed on the rotating rod 7 will rotate accordingly, and the roller brush 5 will clean the snow on the road. In this process, the first gear 8 will also drive the other first gear 8 to rotate in the opposite direction through the two meshing second gears 9, so that the other roller brush 5 rotates in the opposite direction to clean the snow. Since the two roller brushes 5 rotate in the opposite directions, the snow will be swept to both sides of the road surface.

[0051] In this embodiment, when the motor 10 is started, the output end of the motor 10 will drive one of the rotating rods 7 to rotate. Due to the meshing relationship between the first gear 8 and the second gear 9, the other rotating rod 7 will rotate in the opposite direction. At the same time, the first bevel gear 11 will also rotate with the other rotating rod 7.

[0052] As a further solution of the utility model, the transmission structure includes an axle 12 horizontally rotatably arranged on the vehicle body 1 and a fixing frame 14 arranged on the vehicle body 1, and the end of the axle 12 is connected to the driving wheel 4;

[0069] Since the two ends of the lifting rod 21 are respectively located inside the two T-shaped slide grooves 30 and slide in cooperation with each other, the lifting rod 21 and the two protective plates 20 can slide in cooperation with each other vertically;

[0070] The two snow guards 31 are mainly used to block the rear of the roller brush 5 to prevent the accumulated snow from being thrown to the middle of the vehicle body 1 by the inertia generated when the roller brush 5 is cleaning, thereby ensuring the cleanliness of the cleaning.
