Snow Blower Orientation Adjustment via Hydraulic Dynamics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Snow blowers attached to vehicles face challenges with lateral movement during cornering, especially in deep and solid snow conditions, leading to ineffective snow clearing and safety risks due to uncontrolled ejection of snow and ice lumps.
Innovation Solution
The snow blower is equipped with adjustable hydraulic cylinders and a force limiting device, including a pressure relief valve, allowing for automatic or semi-automatic adjustment based on steering angle and wheel position, enabling perpendicular snow pickup and preventing damage from solid objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the snow blower is kept fixed relative to the vehicle, then the structure is simple, but lateral movement during cornering prevents effective snow clearing
Solution Approach 1:
The snow blower is equipped with hydraulic adjustment devices that enable dynamic repositioning during operation. The cutting device can be laterally shifted and rotated relative to the vehicle body through hydraulic cylinders, allowing the snow blower to adapt its position during cornering while maintaining a relatively simple overall structure.
Solution Approach 2:
Hydraulic cylinders are used to provide the forcing means for lateral adjustment and rotation of the cutting device. The hydraulic system enables smooth, controlled movement of the snow blower components without requiring complex mechanical linkages or manual intervention.
2Productivity
If the cutter is open at the side to allow snow entry, then cornering is improved, but clearing quality deteriorates and safety risks increase
Solution Approach 1:
Instead of permanently opening the cutter side, the invention uses a dynamically adjustable cutting device that can be laterally shifted toward the outside of the curve during cornering. This maintains the closed cutter structure for safety and quality while enabling effective cornering through positional adjustment.
Solution Approach 2:
The snow blower performs preliminary lateral movement and rotation of the cutting device before entering the curve. This preliminary positioning ensures the cutter is optimally aligned for cornering, allowing the closed cutter structure to effectively clear snow without compromising safety or quality.
3Productivity
If the milled lane is widened by driving back and forth, then cornering becomes possible, but time consumption and fuel consumption increase
Solution Approach 1:
The hydraulic adjustment system enables the cutting device to dynamically shift laterally and rotate during cornering, allowing the snow blower to clear snow in a single pass through curves. This eliminates the need for multiple back-and-forth passes, reducing both time and fuel consumption.
Solution Approach 2:
The invention replaces the mechanical approach of widening the lane through multiple passes with a hydraulic adjustment system that enables direct cornering. The hydraulic cylinders provide the necessary forcing means to reposition the cutting device, substituting complex multi-pass mechanical operations with a more efficient hydraulic positioning system.
4Device complexity
If manual resetting of force limiting device is required, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The force limiting device is designed to automatically reset after activating the pressure relief valve. When excessive force is detected, the valve releases pressure and the system self-resets without requiring manual intervention from the operator, combining simplicity with ease of operation.
Solution Approach 2:
The force limiting device incorporates a pressure relief valve that provides feedback on excessive forces. When the valve activates due to excessive pressure, it automatically resets the system after releasing the pressure, creating a self-regulating mechanism that responds to operational conditions without manual input.
