It is particularly common in areas with heavy snowfall in the north. The existing snow throwers have the following deficiencies: 1. When the snow thrower is operating, it needs to perform snow cutting and snow throwing operations simultaneously, and requires multiple sets of transmission structures, which are complex; 2. Since snow cutting and snow throwing equipment are arranged in front of the snow thrower, the front line of sight is blocked and the blind area is large; 3. The snow throwing direction is fixed and cannot be flexibly adjusted according to different road conditions. To solve the above problems, our company has designed and proposed a snow thrower.

[0028] Embodiment 1

[0029] See Figures 1-6, A snow thrower, including a frame 1. The girder of the frame 1 is made of 30-mm thick low-alloy manganese plate, which can withstand impact loads and has a strong load-bearing capacity. A snow-throwing reducer crossbeam is provided at the front end, a bridge drive motor bracket is assembled in the middle, and a spring steel plate connection seat is provided at the rear. A cab 2 is provided at the front of the frame 1, and a carriage 7 is provided at the rear. The front end of the cab 2 is provided with a forward-tilted windshield 21. The two sides of the windshield 21 are of an arc structure. The windshield 21 is made of a large-piece forward-tilted arc-shaped electrically heated glass, maximizing the driver's field of vision. An extended handrail is installed on the side of the carriage 7 to ensure the safety of the driver and passengers. On both sides of the top of the cab 2, there are headlamps 22. The upper-mounted headlamps 22 can provide better lighting for the front. A snow-cutting wheel 3 is provided in front of the cab 2. The snow-cutting wheel 3 is of a spiral structure and is symmetrically arranged in a snow pusher 31. A transmission box 32 is provided between the two snow-cutting wheels 3. The outer edge of the snow-cutting wheel 3 is provided with pointed cones 33 along the spiral direction. The pointed cones 33 are inclined in the direction of rotation. The setting of the pointed cones 33 can effectively crush hard ice structures such as wind-driven snow. To enhance the strength of the snow-cutting wheel 3, spiral reinforcing ribs with the same pitch are welded on the back of the snow-cutting wheel 3.

[0030] Behind the snow pusher 31 and at the middle position, a snow-throwing bin 4 is rotatably connected. The back of the snow-throwing bin 4 is rotatably connected to a turntable seat 44. A bearing is provided between the turntable seat 44 and the snow-throwing bin 4. The turntable seat 44 is fixedly connected to the frame 1. Through the turntable seat 44, the snow-throwing bin 4 can rotate on the frame 1. To control the left and right rotation of the snow-throwing bin 4, a rotation drive device for driving the left and right rotation of the snow-throwing bin 4 is provided on the frame 1. Among them, the rotation drive device includes a toothed disk 42. The toothed disk 42 is arc-shaped and is fixedly arranged on the outer side of the back of the snow-throwing bin 4. A drum motor 43 is fixedly provided on the frame 1. The output end of the drum motor 43 is engaged with the toothed disk 42 through a gear, for driving the snow-throwing bin 4 to rotate left or right, and the snow-throwing bin 4 can rotate 35 0 degrees to the left or 60 0During snow removal, the snow throwing bin 4 can be directly rotated to the left or right to throw snow according to different road conditions, so as to achieve efficient snow removal. A snow throwing cylinder 41 is provided on one side of the top of the snow throwing bin 4. The setting of the snow throwing cylinder 41 can guide the direction of snow throwing. The front end opening of the snow throwing bin 4 is connected to the inside of the push shovel 31. A snow throwing wheel 6 is provided in the snow throwing bin 4. A snow throwing wheel rotating shaft 61 is provided in the middle of the snow throwing wheel 6. A power output device is arranged in the carriage 7, and the power output device is a diesel engine. The power output device is rear-mounted to ensure that the center of gravity of the whole vehicle remains balanced. Considering that the center of gravity of the whole vehicle moves forward after the snow throwing equipment is hooked up to the front end of the vehicle, a diesel tank made of thickened steel plate is arranged at the rear of the vehicle, which can be used as a counterweight and provide fuel for the vehicle. A transmission shaft 11 connected to the power output device is arranged in the frame 1. The transmission shaft 11 is fixedly connected to the snow throwing wheel shaft 61 and the transmission box 32 in sequence through a universal joint connecting rod 12, and is used to drive the snow cutting wheel 3 and the snow throwing wheel 6 to rotate synchronously. The use of one transmission shaft 11 can simultaneously drive the snow cutting wheel 3 and the snow throwing wheel 6 to rotate synchronously, and the complementary influence between them can simplify the transmission structure while also reducing the failure rate.

[0031] The vehicle further comprises a lifting device, which is arranged between the cab 2 and the frame 1 and is used for lifting the cab 2. The lifting device comprises a lifting frame 23 of a double fork arm structure and a lifting drive device 24. The lifting frame 23 is distributed on both sides of the frame 1, wherein the two ends of the lifting frame 23 are respectively movably connected to the frame 1 and the cab 2. The lifting drive device 24 is fixedly arranged on the frame 1, and the telescopic end of the lifting drive device 24 is fixedly connected to the cab 2. The lifting drive device 24 is a telescopic cylinder, and the power is provided by the power output device of the snow thrower. The cab 2 can be lifted 500 mm to ensure the safety and efficiency of the snow clearing operation.

[0032] The snow thrower of the present invention uses the same transmission assembly to realize synchronous rotation of the snow cutting wheel 3 and the snow throwing wheel 6, thus simplifying the transmission structure and reducing the failure rate. A liftable cab 2 is adopted, and during snow removal operations, the driver can raise the cab 2 as needed to improve the field of vision and reduce blind spots. In addition, during snow removal operations, a rotatable snow throwing bin 4 is adopted to adjust the snow throwing direction as needed, which can effectively improve the snow removal efficiency.
