Boom-Mounted Pump Counterbalance Layout for Stable Manure Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Boom mounted pumps used for liquid manure lagoons face instability on uneven ground, requiring long stabilizer legs that limit vehicle space and increase the risk of hydraulic swivel failures due to complex fluid line arrangements.
Innovation Solution
A liquid pumping vehicle design with a rotatable platform and articulated boom, where the engine and additional liquid pump act as counterbalances to stabilize the vehicle, allowing shorter stabilizer legs and eliminating the need for complex hydraulic swivels by housing fluid conduits within the boom or frame, enhancing stability and reducing the risk of hydraulic failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If long stabilizer legs are used to compensate for vehicle instability on uneven ground, then vehicle stability is improved, but the vehicle footprint increases and space availability is reduced
Solution Approach 1:
The patent positions the engine and additional liquid pump on the platform to act as counterweights that balance the boom's weight. This counterbalancing mechanism stabilizes the vehicle on uneven ground without requiring long stabilizer legs, thereby reducing the vehicle footprint while maintaining stability.
2Adaptability or versatility
If complex hydraulic swivel arrangements are used to accommodate boom rotation, then boom mobility is improved, but the risk of hydraulic failures increases
Solution Approach 1:
The patent eliminates complex hydraulic swivel arrangements by routing fluid conduits through the boom structure itself rather than through external swivel joints. This extraction of the hydraulic system from vulnerable swivel points removes the risk of hydraulic failures while preserving boom mobility.
Solution Approach 2:
The patent houses fluid conduits within the boom structure, nesting the hydraulic system inside the boom rather than having external connections. This nested arrangement protects the hydraulic system from external damage and eliminates the need for external swivel joints, improving reliability while maintaining mobility.
3Stability of the object's composition
If the engine is positioned to counterbalance the boom, then vehicle stability is improved, but the platform becomes top-heavy
Solution Approach 1:
The patent combines the engine with an additional liquid pump, merging two components into a single integrated unit on the platform. This consolidation achieves the counterbalancing function needed for stability while distributing the weight more efficiently, reducing the top-heavy effect and structural stress on the platform.
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 provides greater stability on unstable ground, reduces the vehicle footprint, and increases the usable boom length while minimizing the risk of hydraulic swivel failures, making it suitable for space-restricted areas and improving pumping efficiency.
Implementation Method 1
the engine situated so that the rotation axis of the platform is between the boom and the engine and so that a first turning moment created on a first moment arm relative to the rotation axis by weight of the engine and other components on an engine-side of the platform is balanced under operational conditions of the pumping vehicle by a second turning moment created on a second moment arm relative to the rotation axis by weight of the boom and other components on a boom-side of the platform

AI summary
A liquid pumping vehicle has: a platform rotatably mounted on a frame; an articulated boom mounted on the platform; a first liquid pump mounted on the boom; a second liquid pump mounted on the platform on the engine-side, the second liquid pump in fluid connection with a fluid conduit through which the first liquid pump pumps the liquid, and an engine mounted on the platform, so that a rotation axis of the platform is between the boom and the engine and so that a weight of the engine, the second liquid pump and other components on an engine-side of the platform acts as a counterbalance to a weight of the boom and other components on a boom-side of the platform; and, The vehicle is better balanced for greater stability when in use for pumping a liquid, e.g., liquid manure.
