Rigid Pipe Manure Distributor Arm Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing liquid manure spreader systems experience significant wear and tear due to the use of flexible hoses in the fluid connection system, which are subjected to constant stress and pressure during pivoting movements, necessitating regular checks and replacements.
Innovation Solution
The implementation of rigid pipes as part of the fluid connection system between the liquid manure tank and distribution tank, which serve both as a support structure and a means of transporting liquid manure, eliminating the need for flexible hoses and reducing wear and tear, while also allowing for increased spreader arm width by adding additional pivotable arms and nozzles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flexible hoses are used in the fluid connection system to enable pivoting movements of distributor arms, then ease of operation is improved, but reliability deteriorates due to constant wear and tear
Solution Approach 1:
The patent combines the support structure function and fluid transport function into a single rigid component. The rigid pipe serves both as the structural support for the distributor arm and as the fluid connection system for transporting liquid manure, eliminating the need for separate flexible hoses and thereby resolving the contradiction between ease of pivoting and wear resistance.
Solution Approach 2:
The rigid pipe performs multiple functions simultaneously: it provides structural support for the distributor arm, serves as the fluid connection system for manure transport, and acts as a mounting structure for nozzles. This multi-functionality eliminates the need for separate flexible hoses, resolving the contradiction between operational ease and reliability.
2Reliability
If rigid pipes are used instead of flexible hoses in the fluid connection system, then reliability is improved by eliminating wear and tear, but ease of operation deteriorates due to restricted pivoting movement
Solution Approach 1:
The patent merges the support structure and fluid transport into a single rigid component designed to pivot. The rigid pipe is integrated into the distributor arm structure, allowing the entire assembly to pivot as one unit while maintaining the reliability benefits of rigid construction throughout the fluid connection system.
Solution Approach 2:
The rigid pipe structure is designed to be dynamic rather than static. The entire rigid pipe assembly pivots as part of the distributor arm mechanism, enabling movement while maintaining the structural integrity and wear resistance of rigid construction. This resolves the contradiction by making the rigid system dynamically capable of pivoting.
3Productivity
If the spreader arm width is increased to cover more arable land, then productivity is improved, but device complexity increases due to additional arms and fluid connections
Solution Approach 1:
The patent combines multiple distributor arms into a single integrated rigid structure with unified fluid transport. Instead of separate arms with individual flexible hoses, the rigid pipe system integrates fluid transport across multiple arms, reducing the number of connection points and simplifying the overall system while maintaining wide coverage capability.
Solution Approach 2:
The rigid pipe structure serves as both the support framework and the fluid transport system across all distributor arms. This universal dual-functionality eliminates the need for separate flexible hose connections at each arm junction, reducing system complexity while enabling extended spreader arm width for increased productivity.
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
This design reduces the wear and tear on the fluid connection system, lowers costs, and allows for a wider spread of liquid manure coverage without the need for frequent hose replacements, enhancing the durability and efficiency of the distribution process.
Implementation Method 1
By designing the swiveling distributor arms with at least one rigid pipe, which forms part of the fluid connection system between the liquid manure tank and liquid manure distribution tank
Implementation Method 2
The outlets (18) are connected to nozzles (21) via flexible hose connections (23). The distributor arms (4, 5, 6, 7) are expediently dimensioned in such a way that, together in the deployment position, they have a length transverse to the direction of travel of at least 10 m
