Description

Technical Field

[0001] This utility model relates to the field of snow removal technology, specifically a roller blower snow removal vehicle. Background Technology

[0002] Snowfall covers a vast area in my country, with snow quality exhibiting diverse forms such as compacted snow, frozen snow, and mixed snow. Furthermore, due to the intensifying impact of climate change, extreme snowstorms are becoming more frequent. Snow removal operations on airport runways, highways, and urban roads are directly related to public safety, making the demand for efficient snow removal equipment urgent. Currently, the mainstream snow removal equipment includes three categories: hot air blowing, cold air blowing, and manual snow removal.

[0003] While existing hot-blowing equipment has efficient snow removal capabilities, the high-temperature gas generated by its aircraft engine causes significant damage to the road surface. In addition, hot-blowing snow removal vehicles have high fuel consumption and operating costs, and the noise level of the vehicles exceeds 100 decibels during operation, resulting in a poor working environment for the workers.

[0004] Manual snow removal is inefficient, labor-intensive for workers, and difficult to cope with severe snow conditions with an average daily snow accumulation of over 30mm.

[0005] Existing cold-blowing equipment is mostly based on commercial chassis modifications, which have drawbacks such as mismatch between chassis power and superstructure power, limited modification space leading to difficulties in maintaining key components, and insufficient visibility from the cab. These results in low snow removal efficiency and high overall operating costs. Therefore, corresponding technical solutions need to be designed to address these issues. Utility Model Content

[0099] The chassis assembly 1 provides the vehicle's driving power, the superstructure power assembly 7 provides the power source for the hydraulic system 5, and the flywheel of the superstructure power assembly 7 is connected to the snow blowing hydraulic pump 502 through the coupling 705. The snow blowing hydraulic pump 502 drives the snow blowing drive motor 505 to provide power to the blower 301. The air volume or wind speed can be adjusted by the blower speed knob in the electronic control system 6 to achieve large air volume or high wind speed snow blowing operations. At the same time, the blower 301 can also blow away the compacted snow generated during the driving process of the chassis assembly 1, improving the snow removal efficiency of the whole vehicle.

[0100] Example 3: Combined snow roller and snow blower operations

[0101] Depending on the conditions at the work site, one operator uses the operating handle of the electronic control system 6 to control the snow roller assembly 2 and the snow blowing assembly 3 to adjust to a suitable ground clearance. The operator also uses the operating handle in the electronic control system 6 to adjust the left and right swing angle of the snow roller assembly 2 and the left and right wind direction of the outlet of the snow blowing assembly 3.

[0102] The chassis assembly 1 provides the vehicle's driving power, while the superstructure power assembly 7 provides the power source for the hydraulic system 5. The operator automatically adjusts the speed of the snow roller assembly 2 through the electronic control system 6 to ensure that the roller speed matches the vehicle's driving speed. During operation, the brush compensation cylinder 511 of the electronic control system 6 automatically adjusts the ground height of the brush 208 to achieve the automatic compensation function of the brush 208. This allows the vehicle to achieve the best snow removal effect while minimizing the wear of the brush 208, extending the service life of the brush 208, and significantly improving snow removal efficiency. The air volume or wind speed can be adjusted by the fan speed knob in the electronic control system 6 to achieve combined snow roller and snow blowing operations. At the same time, the fan 301 can also blow away the compacted snow generated during the driving of the chassis assembly 1, improving the overall snow removal efficiency of the vehicle.

[0103] Example 4: Site Transfer Operation

[0104] Depending on the conditions at the work site, one operator can use the control handle of the electronic control system 6 to adjust the snow roller assembly 2 and the snow blowing assembly 3 to a suitable ground clearance. The locking pin 902 is inserted into the limit block of the snow roller assembly 2, and the transfer bracket 207 is installed at both ends of the snow roller assembly 2. With this solution, the snow roller blowing vehicle can quickly enter or leave the work site. The operation can be completed by only one operator, making the operation convenient.
