Multifunctional snow shovel and manufacturing method

Abstract

The invention relates to a multifunctional snow shovel and a manufacturing method. A loose snow removal shovel blade is connected with a shovel blade support plate, a spring screw nut bracket is connected with the shovel blade support plate and a spring screw nut, a solid snow removal shovel blade is connected with a shovel blade fixing plate, the shovel blade bracket is connected with a shovel blade fixing plate and a spring seat bracket, and a spring is arranged between the spring screw nut and the spring seat. Under the action of larger stress, the solid snow removal shovel blade is easily cut into the solid snow layer on a road pavement, the solid snow layer on the road pavement is thoroughly stripped and cleaned from the road pavement, and when a convex object with certain height exists on the road pavement, the solid snow removal shovel blade is turned backwards to automatically go across the convex object; when the loose snow needs to be quickly removed from the road pavement, a rotary plate can drive all structures to rotate with 180 degrees through a rotary shaft, the loose snow on the road pavement can be cleaned by the loose snow removal shovel blade which has a larger inclining angle with the road pavement, and when the convex object with certain height exists on the road pavement, the loose snow removal shovel blade is turned backwards to automatically go across the convex object.

Description

technical field [0001] The invention relates to the technical field of winter road snow removal machinery and equipment, in particular to a multipurpose snow removal shovel and a manufacturing method thereof. Background technique [0002] In winter road snow removal operations, the angle between the shovel blade and the road surface is small to effectively remove the compacted snow on the road. Because of the structure, when the angle between the shovel blade and the road surface is small, the operation speed is slow, and it is not suitable for quick removal of soft snow on the road. When the angle between the shovel blade and the road surface is large, the operation speed is faster. It is suitable for clearing soft snow on the road. No matter clearing compacted snow or soft snow, the shovel edge needs to be used when encountering a protruding object with a certain height on the road surface. automatically bypassed. At present, the included angle between the shovel edge of ...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the excessive angle formed between the shovel edge of the existing snow removal shovel and the road surface, it is not suitable for removing compacted snow, even the soft snow removal effect is not good, and it cannot be very good when encountering a protruding object with a certain height on the road surface The snow removal shovel is often damaged, resulting in very low snow removal efficiency and increasing the cost of snow removal operations. The invention provides a multi-purpose snow removal shovel and its manufacturing method. The snow removal shovel has two blades with different angles. When removing compacted snow in snow removal operations, use the shovel blade with a smaller angle with the road surface to clear it. , the snow removal shovel can automatically cross over when encountering a protruding object on the road surface at a certain height, which improves the snow removal efficiency and reduces the snow removal operation cost
