[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Please refer to Figure 1-Figure 7 .

[0033] Embodiment 1

[0034] like Figure 1-Figure 7As shown, the present embodiment provides a snow removal vehicle, comprising a vehicle body 1, a snow removal device 2 and an angle adjustment mechanism 3 connected between the vehicle body 1 and the snow removal device 2, wherein the snow removal device 2 can be a snow removal shovel 7, a snow sweeping mechanism 8 or a combination of the two, or can be other commonly used devices for snow removal; the angle adjustment mechanism 3 is used to adjust the horizontal angle and the pitch angle of the snow removal device 2, and comprises a universal joint 4, a left and right adjustment push rod 5 and a pitch adjustment push rod 6, the left and right adjustment push rod 5 and the pitch adjustment push rod 6 can be any device capable of realizing a pushing function, such as an electric push rod, a pneumatic push rod or a hydraulic push rod, and in the present embodiment, an electric push rod is preferably used, the snow removal device 2 is fixedly connected to the vehicle body 1 through the universal joint 4, and the universal joint 4 is located behind the snow removal device 2 along the traveling direction of the vehicle body 1, and when adjusting the working angle of the snow removal device 2 The snow removal device 2 is connected to the vehicle body 1 through the universal joint 4 arranged at the rear, and the movable ends of the left and right adjustment push rods 5 are fixedly connected to the left or right side of the snow removal device 2, and the movable end of the pitch adjustment push rod 6 is fixedly connected to the upper part or the lower part of the snow removal device 2, thereby realizing the left and right angles and pitch angles adjustment of the snow removal device 2, so as to better adapt to the snow removal in complex terrain and achieve better cleaning effect.

[0035] In order to achieve a better snow removal effect, the snow removal device 2 includes a snow removal shovel 7 and a snow sweeping mechanism 8 which are arranged in sequence along the direction of travel. The snow removal shovel 7 removes a large amount of snow, and the remaining small amount of snow after shoveling is cleared by the snow sweeping mechanism 8; the snow removal shovel 7 is fixedly connected to the snow sweeping mechanism 8, the movable end of the pitch adjustment push rod 6 is fixedly connected to the upper part of the snow removal shovel 7, and the movable end of the left and right adjustment push rod 5 is fixedly connected to the left or right side of the snow sweeping mechanism 8; thereby, the snow removal shovel 7 and the snow sweeping mechanism 8 can be adjusted in angle through the angle adjustment mechanism 3 to better adapt to complex terrain.

[0036] Furthermore, the snow-clearing mechanism 8 includes a snow-clearing roller brush 9 and a snow conveying mechanism which are sequentially arranged along the direction of travel, the snow conveying mechanism including a snow-moving shell 10 and a snow-moving auger 11 which is arranged in the snow-moving shell 10, wherein the snow-clearing roller brush 9 is rotatably connected to the snow removal shovel 7, and the snow conveying mechanism is fixedly connected to the snow removal shovel 7 through the snow-moving shell 10, the snow-moving shell 10 is provided with an opening on the side facing the snow-clearing roller brush 9, and the bottom surface extends to below the snow-clearing roller brush 9, and a snow outlet 12 is provided on one side of the snow-moving shell 10 opposite to the snow-moving auger 11; by extending the bottom surface of the snow-moving shell 10 to below the snow-clearing roller brush 9, the snow brought up by the snow-clearing roller brush 9 through rotation can better fall into the snow-moving shell 10, and then continuously transported to one side by the snow-moving auger 11, the accumulated snow is discharged to the uncleared side of the road, so that the snow clearing at the position where the snow removal vehicle passes can be cleared more thoroughly.

[0037] Furthermore, a protrusion 13 is provided on the bottom surface of the snow-moving shell 10, between the snow-clearing roller brush 9 and the snow-moving auger 11. The protrusion 13 and the adjacent sides of the snow-clearing roller brush 9 and the snow-moving auger 11 are all sloped surfaces. The accumulated snow brought up by the snow-clearing roller brush 9 moves upward along the sloped surface and with the snow-clearing roller brush 9. After moving a certain distance, it is separated from the snow-clearing roller brush 9 and falls into the snow-moving shell 10. The protrusion 13 with sloped surfaces on both sides prevents the accumulated snow that has fallen into the snow-moving shell 10 from falling onto the road again, and at the same time does not form an obstacle for the snow-clearing roller brush 9 to sweep the accumulated snow into the snow-moving shell 10.

[0038] Furthermore, the snow-clearing mechanism 8 also includes a snow-clearing drive device, which includes a snow-clearing motor 14 and a gear group 15 connected to the snow-clearing motor 14. The gear group 15 drives the snow-clearing roller brush 9 and the snow-moving auger 11 respectively. By connecting the snow-clearing motor 14 to the gear group 15, the snow-clearing roller brush 9 and the snow-moving auger 11 are driven at the same time, which ensures that the two can work synchronously and also reduces the cost.

[0039] Furthermore, in order to make the snow removal vehicle more functional, it also includes a de-icing module 16 arranged behind the snow removal device 2 along the direction of travel. The de-icing module 16 includes a de-icing roller 17 and a height adjustment mechanism for adjusting the height of the de-icing roller 17. The de-icing roller 17 is a certain distance away from the ground in a non-working state. When the road surface or the roof is frozen and needs to be broken, the de-icing roller 17 is lowered to a position below the ice layer through the height adjustment mechanism to perform ice breaking. The de-icing roller 17 is spiral in shape, which can break ice and transport some broken ice to one side of the road at the same time.

[0040] The deicing module 16 also includes a deicing cover 21, which is arranged above the deicing roller 17 and covers the left side, right side and top of the deicing roller 17, thereby preventing the deicing roller 17 from picking up ice cubes and throwing them to other parts of the vehicle body 1 or the road surface.

[0041] As a preferred embodiment, the height adjustment mechanism includes a deicing push rod 18 fixedly connected to the vehicle body 1, a booster block 19 hinged to the movable end of the deicing push rod 18, and a four-bar mechanism 20 hinged to the booster block 19, wherein the four-bar mechanism 20 is arranged at both ends of the deicing roller 17 to ensure that the deicing roller 17 is more stable, and the four-bar mechanism 20 at one end is connected to the deicing push rod 18, and the deicing push rod 18 can be an electric push rod, a pneumatic push rod or a hydraulic push rod, preferably an electric push rod. The deicing push rod 18 drives the four-bar mechanism 20 through the booster block 19 to raise or lower the position of the deicing roller 17, so that the deicing roller 17 is in a non-working state or a working state, and at the same time, the extension amount of the deicing push rod 18 can be adjusted according to the thickness of the ice layer to adapt to different ice layer thicknesses; when the deicing roller 17 is at the lowest point, the four-bar mechanism 20 is preferably in a dead point position, thereby making the deicing roller 17 more stable when subjected to ice breaking force.

[0042] Furthermore, it also includes a traveling module, which includes a driving gear 22, a plurality of traction wheels 23 and a crawler track 24. The driving gear 22 is arranged at the rear of the traveling module along the traveling direction. The driving gear 22 is driven to rotate by a motor. The crawler track 24 is connected to the driving gear 22 and the plurality of traction wheels 23. Through the above arrangement, the driving of the snow removal vehicle is more stable, ensuring smooth travel and stable operation even in complex terrain.

[0043] Embodiment 2

[0044] like Figure 1-Figure 7 As shown, this embodiment provides a snow and ice removal method, which uses the snow removal vehicle in the first embodiment to remove snow and ice, including the following steps:

[0045] 1) First, adjust the working angle of the snow removal device 2 according to the terrain conditions, so that the snow removal device 2 is in the working position, start the moving module to make the snow removal vehicle move forward, and start the snow removal device 2 to remove the snow on the road;

[0046] 2) When the road surface is uneven or there are obstacles, the working angle of the snow removal device 2 is adjusted by adjusting the push rod 5 left and right and / or the pitch adjustment push rod 6, so that the snow removal device 2 can remove more snow at this angle and can remove the snow more thoroughly;

[0047] 3) When the road surface is not frozen, the above steps are used to complete the snow removal; when the road surface is frozen, the deicing roller 17 is lowered and reaches below the ice layer through the height adjustment mechanism to break the ice layer.

[0048] Furthermore, step 1) includes first using the snow shovel 7 located in the front to shovel the snow, and then using the snow roller brush 9 to clear the snow that has not been cleared by the snow shovel 7, and then transporting it to one side of the vehicle body 1 through the snow transport mechanism and discharging it from the snow outlet 12.
