Snow shovel obstacle avoidance device

Abstract

The invention discloses a snow shovel obstacle avoidance device. The snow shovel obstacle avoidance device comprises a shovel body and shovel blades; each shovel blade is arranged at a lower edge of the shovel body through an obstacle avoidance linkage mechanism and laminated on the shovel body; each obstacle avoidance linkage mechanism is composed of a bracket, a front rocker arm, a rear rocker arm, and a pressure expansion link; the bracket is hinged with the shovel body through a front rocking bar and a rear rocking bar to form a parallelogram structure; one end of the pressure expansion link is hinged on the shovel body, and the other end is hinged on a rear end of the bracket; and the shovel blade is arranged on the front end of the bracket. Multiple sets of shovel blade and the obstacle avoidance linkage mechanism are provided, various shovel blades are continuously arranged along the shovel body curve. A support wheel is arranged at a lower part of the shovel body back to support the shovel body to maintain the set distance with the ground. Multiple groups of shovel blades are parallel connected; when the obstacle avoidance device encounter obstacles, the other shovel bladescan shovel the snow wne single shovel blade is in obstacle avoidance. The device is compact in structure, small in borne impact force, and reliable in reset function, and can be used for the light snow shovel in a general job size, and can be used for ultra-high job size and high-speed snow-throwing type snow shovel.

Description

Technical field [0001] The invention relates to a snow shovel on snow removal equipment in winter, in particular to a snow shovel obstacle avoidance device, which belongs to the technical application field of engineering machinery snow removal equipment. Background technique [0002] Winter snow removal equipment is currently widely used in various highways and urban roads in our country. Snow removal shovel has become an important equipment for winter snow removal due to its high snow removal efficiency and strong emergency response capability. As we all know, the function of snow removal and obstacle avoidance is one of the core technologies of snow shovel. The good obstacle avoidance function can effectively improve the snow removal efficiency and operation safety of the snow shovel, and meet the requirements of different complex operating conditions. [0003] At present, the obstacle avoidance types and structural principles of various snow removal shovel at home and abroad ar...

AI Technical Summary

Problems solved by technology

This type needs to lift the entire snow shovel, and the impact force is also relatively large. The area left by the overall lifting is large, and the adaptability to complex roads is poor.

[0005] The shovel flip type has the overall width flip or partial segment flip. Generally, a metal tension spring is used as the mechanism reset element. This type is mostly a partial obstacle avoidance action, and the impact force of the mechanism is relatively small; the performance of the metal spring is attenuated, The overturning structure is large, and the reset function of the mechanism often declines significantly after a period of use, which affects the snow removal effect of the snow shovel

[0006] The shovel blade is partially flipped, and the flipped obstacle avoidance structure is only the shovel blade, which does not affect the overall snow removal and snow removal function of the shovel body, and the impact force of the segmented obstacle avoidance is also small; when the mechanism is turned over by the resistance of obstacles, the overall snow shovel needs It is an instantaneous jumping action; similarly, after crossing the obstacle, the shovel blade needs to overcome the weight of the shovel body under the action of the metal compression spring to reset in reverse. The small structural space and the metal spring thrust are small and the reset function is poor, which often requires the operator to take the initiative to reset. Lift the shovel body so that the cutting edge returns under the action of spring force

[0007] The above obstacle avoidance types are generally applied to light snow shovels with light overall weight and large cutting angle, and some even adopt a shovel edge perpendicular to the road surface for easy reset, so the snow removal function is poor, and the operating speed and efficiency are not high.
