Auger Snow Remover Phase Synchronization for Force Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Auger snow-removing machines experience instability due to uneven reaction forces from forward and reverse rotation augers, affecting running stability and efficiency during snow removal.
Innovation Solution
The auger snow-removing machine design synchronizes the rotational speed of forward and reverse rotation augers, with phase adjustments ensuring simultaneous distal end contact with snow, counterbalancing reaction forces and optimizing snow collection and delivery into a blower.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If forward rotation augers and reverse rotation augers operate at different rotational speeds, then snow collection coverage is improved, but running stability deteriorates due to unbalanced reaction forces
Solution Approach 1:
The patent applies counterweight principle by configuring reverse rotation augers to rotate in opposite direction at the same speed as forward rotation augers. The reaction forces generated by the reverse rotation augers counterbalance the reaction forces from the forward rotation augers, eliminating the swaying motion and improving running stability while maintaining effective snow collection coverage.
2Object-generated harmful factors
If distal ends of augers hit snow surface at different times, then individual reaction forces are reduced, but running stability and snow removal efficiency deteriorate
Solution Approach 1:
The patent implements periodic action by synchronizing the rotation phases of forward and reverse rotation augers so that their distal ends simultaneously contact the snow surface at regular intervals. This coordinated periodic contact creates balanced reaction forces that cancel each other out, maintaining running stability while efficiently removing snow.
3Quantity of substance
If forward rotation augers rotate faster than reverse rotation augers, then snow collection capacity is enhanced, but snow removal efficiency deteriorates due to unbalanced reaction forces
Solution Approach 1:
The patent uses counterweight principle to balance the reaction forces generated during snow collection. By operating reverse rotation augers at the same speed as forward rotation augers, the system maintains balanced reaction forces that prevent energy loss from swaying motions, thereby improving overall snow removal efficiency while preserving snow collection capacity.
4Area of stationary object
If augers are configured with different rotational speeds, then snow collection coverage is improved, but energy consumption increases due to unbalanced operation
Solution Approach 1:
The patent applies counterweight principle by synchronizing the rotational speeds of forward and reverse rotation augers. This balance eliminates energy-wasting swaying motions and reduces overall energy consumption while maintaining comprehensive snow collection coverage through coordinated operation of all augers.

AI summary
An auger snow-removing machine (10) includes left and right forward rotation augers (41L, 41R) rotatable in a first direction (Ra) during snow removal and left and right reverse rotation augers (42L, 42R) rotatable in a second direction (Rb) opposite the first direction during the snow removal. The forward and reverse rotation augers are coaxially disposed in alignment in a width direction of an auger housing (21) within the housing. Distal ends (51a, 57a; 52a, 58a) of the left forward rotation auger and the right reverse rotation auger have phases set to substantially simultaneously reach a lowermost location when the forward and reverse rotation augers rotate. Distal ends (53a, 55a; 54a, 56a) of the right forward rotation auger and the left reverse rotation auger have phases set to substantially simultaneously reach the lowermost location when the forward and reverse rotation augers rotate.
