Trailing Shoe Spreader for Liquid Manure Incorporation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for applying liquid manure in grassland often result in forage contamination due to residue issues, influenced by application technique, weather, viscosity, and substrate characteristics, which are not effectively addressed.
Innovation Solution
A trailing shoe spreader with liquid manure hoses and incorporation units that slit open the subsoil and work the manure into the soil as it moves, ensuring efficient infiltration and minimizing above-ground residues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If liquid manure is applied to the surface without incorporation, then application simplicity is improved, but forage contamination increases
Solution Approach 1:
The patent combines the manure application function with the incorporation function into a single trailing shoe applicator unit. The trailing shoes slit the substrate and the incorporation units work the manure into the soil in one continuous operation, eliminating the need for separate application and incorporation passes while preventing forage contamination.
Solution Approach 2:
The trailing shoes perform preliminary action by slitting the substrate surface before the manure is applied. This pre-prepared incisions allow the manure to be directly incorporated into the subsoil as it flows from the hoses, preventing surface residue and forage contamination while maintaining simple operation.
2Object-affected harmful factors
If incorporation units are added to work manure into subsoil, then forage contamination is reduced, but device complexity increases
Solution Approach 1:
The trailing shoe applicator is designed as a multi-functional unit that combines manure delivery, substrate slitting, and manure incorporation into a single device. The incorporation units with radially outward-extending tines serve multiple purposes: incorporating manure, aerating substrate, and controlling application depth, thereby reducing overall device complexity despite adding incorporation capability.
Solution Approach 2:
The incorporation units are segmented with multiple radially outward-extending tines that can independently penetrate and work the substrate. This segmentation allows the incorporation function to be achieved through multiple small elements rather than one large complex mechanism, reducing overall device complexity while effectively reducing forage contamination.
3Productivity
If trailing shoes slit the surface before manure application, then manure incorporation efficiency is improved, but application complexity increases
Solution Approach 1:
The substrate-slitting function and manure application function are merged into a single trailing shoe unit. The trailing shoes continuously slit the substrate while the hoses simultaneously deliver manure into the incisions, achieving high incorporation efficiency without requiring separate operations or complex coordination mechanisms.
Solution Approach 2:
The trailing shoes automatically slit the substrate and create incisions that guide the manure flow directly into the subsoil. The system is self-sufficient in that the slitting action itself prepares the path for manure incorporation without requiring additional guidance mechanisms or complex control systems, maintaining simplicity while improving efficiency.
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 trailing shoe spreader effectively incorporates liquid manure into the subsoil in a single step, reducing forage contamination and enhancing nutrient distribution, while allowing for adjustable penetration depth and angle of attack to accommodate varying conditions.
Implementation Method 1
The trailing shoes and incorporation units can also be attached, at least indirectly, to these spring tines, which exert a spring force on the trailing shoes and incorporation units towards the soil.
Implementation Method 2
This is achieved through the mechanical action of the incorporation units, which, as the trailing shoe applicator moves along, roll over the already applied slurry and work it into the soil.

AI summary
The invention relates to a trailing shoe distributor (10) for distributing liquid manure, comprising several liquid manure hoses (14) with outlet openings for applying the liquid manure to a substrate; several trailing shoes (20) which, in a working position of the trailing shoe distributor (10), are designed to slit the substrate before the liquid manure reaches the substrate from the outlet openings; several incorporation units (22) which, in the working position of the trailing shoe distributor (10), are designed to incorporate the applied liquid manure into the substrate by rolling along the surface as the trailing shoe distributor (10) moves along the substrate.
