Segmented Snow Plough Auger for Long-Range Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing snow ploughs with large surface snow-throwing units fail to efficiently discharge snow to a far area due to insufficient centrifugal force near the rotation center, leading to inefficient snow removal as the snow falls back onto a close area and requires additional discharge.
Innovation Solution
A snow plough design featuring a rotating shaft with a snow-collecting unit on one side and a snow-throwing unit at the center, where the snow-throwing unit includes an outer circumferential region with a large centrifugal force to cast snow further away, and an inner circumferential rotating unit to push snow towards the outer region, forming a path for efficient snow movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a large surface snow-throwing unit is used to scoop a large amount of snow, then the snow collection capability is improved, but the centrifugal force near the rotation center becomes insufficient causing snow to fall onto a close area instead of being discharged to a far area
Solution Approach 1:
The snow-throwing unit is segmented into an outer circumferential snow-throwing unit and an inner circumferential rotating unit. The outer unit is responsible for casting snow to a far area using large centrifugal force, while the inner unit pushes snow toward the outer region. This segmentation resolves the contradiction by separating the snow collection function (inner unit) from the snow discharge function (outer unit), allowing each to operate optimally in its designated zone.
Solution Approach 2:
Different regions of the snow-throwing unit are assigned different functions based on their local characteristics. The outer circumferential region, which generates sufficient centrifugal force, is designated for snow discharge. The inner circumferential region, where centrifugal force is insufficient, is designated for snow collection and pushing. This local quality differentiation ensures that snow is handled appropriately at each radial position, preventing the efficiency loss that occurs when snow near the center cannot be discharged effectively.
2Force
If snow is discharged by centrifugal force from the inner circumferential region, then the snow can be moved outward, but the centrifugal force is too small causing the snow to fall onto a close area rather than being casted to a far area
Solution Approach 1:
The snow-throwing unit is divided into inner and outer circumferential regions with distinct functions. The inner circumferential rotating unit pushes snow outward, while the outer circumferential snow-throwing unit casts snow to a far area using sufficient centrifugal force. This segmentation allows snow to be progressively moved from the low-force inner region to the high-force outer region, achieving both outward movement and long-distance discharge.
Solution Approach 2:
The outer circumferential snow-throwing unit acts as an intermediary that receives snow from the inner circumferential rotating unit and then casts it to a far area. This intermediary structure allows snow to be transferred from a region with insufficient centrifugal force to a region with sufficient centrifugal force, resolving the contradiction between moving snow outward and discharging it to a far area.
3Device complexity
If the snow-throwing unit rotates along the entire circumferential region, then the structure is simple, but snow scatters and non-uniformity is formed reducing work efficiency
Solution Approach 1:
The snow-throwing unit is segmented into an outer circumferential snow-throwing unit and an inner circumferential rotating unit with distinct functions. This segmentation prevents snow scattering by assigning specific roles to each region: the inner unit pushes snow outward while the outer unit casts it to a far area. The clear functional division maintains structural simplicity while eliminating the inefficiency of uniform rotation across the entire circumference.
Solution Approach 2:
Different functional qualities are assigned to different circumferential regions. The inner circumferential region is optimized for snow collection and pushing, while the outer circumferential region is optimized for snow casting. This local quality differentiation prevents snow non-uniformity and scattering that would occur with uniform rotation, thereby improving work efficiency without significantly increasing structural complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design enables efficient snow discharge to a far area by utilizing the large centrifugal force of the outer snow-throwing unit and the inner rotating unit to prevent snow scattering and improve work efficiency by preventing snow non-uniformity and enhancing snow removal distance.
Implementation Method 1

AI summary
A snow plough includes a driving source, an auger housing, a rotating shaft to be driven and rotated by the driving source within the auger housing, and an auger arranged within the auger housing and to be driven and rotated via the rotating shaft. The auger includes a snow-collecting blade located at least on one side in a width direction of the auger, the snow-collecting blade collecting snow toward a center of the auger in the width direction, and a snow-throwing blade located at the center of the auger in the width direction, the snow-throwing unit casting snow collected by the snow-collecting blade by a centrifugal force and discharging snow to an outside via a chute. The snow-throwing blade includes an outer circumferential snow-throwing plate rotating along an outer circumferential region positioned outside an inner circumferential region, the inner circumferential region being a non-snow-throwing region within the auger housing.
