Vehicular Auger Implement Double 4-Bar Linkage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicular auger implements require two operators to maintain vertical alignment and stability, especially on uneven terrain, and often necessitate separate engines for attached implements, which are costly and cumbersome.
Innovation Solution
A vehicular auger implement with a central articulating section using a spring or gas shock counter-balanced double 4-bar linkage, mounted on a vehicle with a hydraulic power take-off, allowing single-operator operation and maintaining vertical alignment on slopes, and a Hoeckens linkage for converting rotational motion into vertical motion without lateral vehicle movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional vehicular auger implement is used, then the auger can be mounted on a vehicle, but two operators are required to maintain vertical alignment and stability
Solution Approach 1:
The linkage mechanism is divided into separate functional components: a four-bar linkage for vertical motion conversion and a Hoeckens linkage for motion path control. This segmentation allows each component to perform its specific function efficiently, reducing the overall operational complexity despite the increased number of parts.
Solution Approach 2:
The patent introduces an intermediary linkage system between the vehicle's power source and the auger. This intermediary mechanism (comprising the four-bar and Hoeckens linkages) acts as a mediator that converts rotational vehicle motion into precise vertical auger motion, eliminating the need for manual alignment by a second operator.
2Power
If separate engines are used for attached implements, then the implement has independent power, but the cost and implement complexity increase
Solution Approach 1:
The vehicle's existing power source is made multi-functional by using it to drive both the vehicle's primary function and the auger implement through the linkage system. This eliminates the need for a separate engine on the implement, reducing complexity and cost while maintaining adequate power delivery.
Solution Approach 2:
The patent merges the vehicle's power source with the implement's power needs by mechanically coupling them through the linkage system. The vehicle's engine serves dual purposes: propelling the vehicle and driving the auger, thereby consolidating power sources and reducing overall system complexity.
3Device complexity
If a simple linkage is used, then the device complexity is reduced, but the ability to maintain vertical alignment on slopes is compromised
Solution Approach 1:
The linkage system is designed with dynamic characteristics that automatically adapt to terrain variations. The four-bar and Hoeckens linkages work together to maintain the auger's vertical orientation through a controlled D-shaped motion path, allowing the system to self-adjust on slopes without requiring complex active control mechanisms.
4Ease of operation
If the vehicle moves laterally during auger operation, then the setup is simpler, but the drilling precision and safety are reduced
Solution Approach 1:
The patent converts the potential harm of lateral vehicle movement into a beneficial controlled motion path. The Hoeckens linkage is specifically designed to guide the auger through a D-shaped path where the curved portion accommodates necessary lateral adjustment while the vertical portion ensures precise vertical drilling, thereby transforming unrestricted lateral movement into controlled, precise motion.

AI summary
A vehicular auger implement includes an auger having a bit; a walk-behind vehicle having front and rear ends, a forward anchor point, and a rear anchor point; linkage coupling the auger to the walk-behind vehicle; and an actuator for causing the linkage to move between raised and lowered configurations. The linkage includes first, second, and third links. The first link is coupled to the walk-behind vehicle and is rotatable about the forward anchor point. The second link is coupled to and is rotatable about the first link. The second link supports the auger. The third link is coupled to and is rotatable about the second link. The third link is also coupled to the walk-behind vehicle and is rotatable about the rear anchor point.
