Background Technology

[0002] In winter snow removal operations, especially on narrow urban roads and sidewalks, traditional large snow removal equipment cannot enter, while existing small equipment often has the following problems: poor obstacle avoidance: the sides of the blade are rigid structures, which are prone to collision when approaching curbs, steps or other obstacles, resulting in equipment damage or road damage; weak road adaptability: most small equipment adopts a three-wheel or four-wheel layout, which is prone to tilting when working on slopes and potholes, resulting in uneven snow removal or even equipment tipping over; insufficient structural stability: the frame structure is simple and lacks elastic buffer and multi-point support design, resulting in poor working effect in complex road conditions.

[0003] Therefore, there is an urgent need for a small, efficient snow removal machine that can automatically avoid obstacles and adapt to complex road conditions. Utility Model Content

[0004] The present invention aims to provide a small snow removal machine with a reasonable structure, flexible obstacle avoidance capability and good road adaptability, so as to solve the problems of collision risk and insufficient stability of existing equipment when operating in narrow and complex road conditions.

[0009] like Figure 1 As shown, a snow removal machine with flexible obstacle avoidance and wheeled adaptability includes a frame 1 and a control system. A snow removal mechanism is located at the front of the frame 1, and a walking mechanism and a hydraulic system for controlling the snow removal mechanism are located below the frame 1. The snow removal mechanism includes a shovel 2, which includes a triangular pusher 13. The triangular pusher 13 is composed of multiple square tubes 4 and iron plates 5 disposed between the square tubes 4. Each of the two triangular sides of the shovel 2 has a baffle 3, which is connected to the shovel 2 via a hinge 8. Fixed seats 11 are located on the upper and lower sides of the baffle 3, and connecting seats 22 are located at corresponding positions on the upper and lower sides of the shovel 2. A shock absorber 15 is provided between the fixed seats 11 and the connecting seats 22. When the baffle 3 contacts obstacles such as curbs, the baffle 3 compresses and slides inward. After the external force disappears, it returns to its original position under the damping action of the shock absorber 15. This design effectively avoids rigid collisions between the equipment and obstacles. A fixed column 16 is provided between the upper and lower connecting seats 22. An electric push rod mounting seat 17 is provided on the fixed column 16. The electric push rod mounting seat 17 is connected to one end of the electric push rod 12, and the other end of the electric push rod 12 is connected to a motor 21 mounted on the shovel plate 2. The motor 21 can be started or stopped by the electric push rod controller in the operating control system. The electric push rod 12 drives the fixed column 16 and the baffle 3 to extend or retract, thereby adjusting the width of the snow-clearing surface and obstacle avoidance. A rubber plate 23 is provided below the shovel plate 2 and the baffle 3. The rubber material of the rubber plate 23 reduces damage to the road surface during snow removal.

[0010] The walking mechanism includes a directional wheel 14 at the foremost end and omnidirectional wheels 7 at the lower ends of both sides of the triangular pusher 13. The directional wheel 14 is mounted via a connecting rod 18, the upper end of which is connected to the front side of a connecting rod 20 located between the two triangular sides of the rear of the triangular part of the triangular pusher 13. The extension of the directional wheel 14 relative to the triangular pusher 13 is adjusted by the connecting rod 18, thereby adjusting the vertical posture of the shovel 2 to adapt to different road slopes. Two sets of hydraulic cylinders 9 are provided above the connecting rod 20, and a high-pressure oil pipe 10 is provided between the two sets of hydraulic cylinders 9. The hydraulic rods at the front end of the hydraulic cylinders 9 are fixedly connected to the motor vehicle. The lifting and lowering adjustment of the shovel and the friction force between the shovel and the ground can be realized through the hydraulic cylinders 9. The control system includes a hydraulic control valve, an electric pusher controller, and an operation panel.

[0011] The control system includes hydraulic control valves, electric actuator controllers, and an operation panel. Operators can adjust the lifting of the shovel, the height of the guide wheels, and the travel speed of the equipment through the control system.

[0012] Working process: Start the equipment, set the blade lifting and front directional wheel height through the control system. When pushing snow in a straight line, the front directional wheel maintains the driving direction, and the rear swivel wheel follows freely. When turning, the operator applies lateral force, and the rear swivel wheel rotates freely to achieve a small radius turn. When encountering roadside obstacles, the baffle automatically retracts to avoid them, protecting the equipment and the road surface. When working on a slope, adjust the height of the front wheel to keep the blade level. After the operation is completed, the blade is raised, and the equipment is transferred to the next work area.

[0013] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope of the present utility model based on the technical solution and the inventive concept of the present utility model are covered within the protection scope of the present utility model.
