Obstacle avoidance type snow sweeping device

Abstract

The invention provides an obstacle avoidance type snow sweeping device. The obstacle avoidance type snow sweeping device comprises a fixed rack (1), a movable rack (6), an obstacle induction and signal transmission mechanism (7), hydraulic valves (8), a snow sweeping roller assembly driving device (10) and a snow sweeping roller assembly (4). The obstacle avoidance type snow sweeping device is characterized in that a movable connecting mechanism is arranged between the fixed rack (1) and the movable rack (6), the snow sweeping roller assembly (4) is arranged on the lower portion of the movable rack (6), and the obstacle induction and signal transmission mechanism (7) is arranged on the lateral of the front portion of the movable rack. Compared with the prior art, the obstacle avoidance type snow sweeping device has the characteristics that the structure is simple; the automation degree is high; the operation width can be increased; the operation path is automatically changed; obstacle avoidance operation is achieved; the operating occasion can be broadened; the application scope is wide; the operating efficiency is high; snow removing is thorough and clean; and the operating speed is high.

Description

technical field [0001] The invention relates to the field of highway driving safety traffic, in particular to an obstacle-avoiding snow removal device. technical background [0002] There is a lot of snow in northern my country in winter, but due to the cold weather, the snow cannot melt in time, and a layer of hard ice will be formed under the long-term rolling of the wheels, causing slippery roads, prone to traffic accidents, and causing many unnecessary personal and property losses For traffic safety, the only way to remove the ice and snow is to remove the snow. At present, the following methods are used: first, manual snow removal is slow, time-consuming and labor-intensive, and requires a lot of investment; Cause salt pollution and corrode the road surface; thirdly, use mechanical snow pushing, this method is fast and effective, but it can only be used on straight and wide urban roads, and the snow near the turning ramps or green belt plants cannot be cleaned and can onl...

[0002] There is a lot of snow in northern my country in winter, but due to the cold weather, the snow cannot melt in time, and a layer of hard ice will be formed under the long-term rolling of the wheels, causing slippery roads, prone to traffic accidents, and causing many unnecessary personal and property losses For traffic safety, the only way to remove the ice and snow is to remove the snow. At present, the following methods are used: first, manual snow removal is slow, time-consuming and labor-intensive, and requires a lot of investment; Cause salt pollution and corrode the road surface; thirdly, use mechanical snow pushing, this method is fast and effective, but it can only be used on straight and wide urban roads, and the snow near the turning ramps or green belt plants cannot be cleaned and can only be piled At the corner of the ramp or around the plants, it occupies the road area, affects the passage of people and vehicles, and also causes snowmelt pollution when the snow melts

[0003] Most of the existing snowplows are fixed-width type, and the snowplowing path is fixed during work. It has poor adaptability to special occasions such as pedestrian crosswalks with rows of green plants, and the snowplowing effect is not ideal; snowplowing devices with variable path function mostly use hydraulic cylinders. The control realizes the left and right movement of the snow-plowing roller, but the expansion and contraction of the oil cylinder is controlled manually. When the driver visually observes the change of the road surface and needs to swing the roller, he presses the switch, and the action of the oil cylinder drives the roller brush to swing.

Due to the artificial control, the control accuracy is not high, and it is easy to cause damage to the roller brush due to untimely control
