Solution Overview
Problem
Current methods for introducing liquid manure containing solids into soil either result in high odor and ammonia emissions, require additional processing steps, or lead to uneven nutrient distribution, causing inefficiencies and maintenance issues due to clogging and blockages in distribution systems.
Innovation Solution
A device with multiple sets of outlet openings at different vertical heights, connected to corresponding discharge openings, allows for the distribution of liquid manure containing solids as parallel strands at varying depths, avoiding cross-sectional constrictions and promoting uniform nutrient distribution without clogging, using a cutting device to comminute solids and prevent blockages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If solid-containing slurry is sprayed above the soil surface using a distribution device, then the manure can be discharged through a relatively large opening with low risk of blockages and achieves favorable distribution near the surface, but significant odor and ammonia emissions occur
Solution Approach 1:
The distribution device is divided into multiple outlet openings (first outlet openings and second outlet openings) arranged at different vertical heights. The slurry is distributed through these segmented outlets to multiple discharge openings, creating multiple parallel strands that are incorporated into the soil. This segmentation allows the system to maintain the ease of discharge through multiple openings while reducing emissions by incorporating the slurry into the soil rather than spraying it on the surface.
2Object-generated harmful factors
If liquid manure is spread over the cultivated area and subsequently incorporated into the soil, then low-odor and low-ammonia-emission incorporation is achieved, but at least two passes over the cultivated area are required, resulting in additional labor, fuel consumption, and material wear
Solution Approach 1:
The distribution device combines multiple outlet openings at different vertical heights into a single integrated system. The first outlet openings discharge slurry at a higher vertical position while the second outlet openings discharge at a lower vertical position. Both are connected to corresponding discharge openings that incorporate the slurry into the soil simultaneously in one pass, eliminating the need for separate spreading and incorporation operations.
3Object-generated harmful factors
If solid-containing slurry is applied through several small openings in multiple tines, then virtually emission-free application is achieved, but the very localized distribution results in unfavorable nutrient distribution across the soil surface
Solution Approach 1:
The distribution device utilizes vertical height as an additional dimension by arranging first outlet openings at a higher vertical position and second outlet openings at a lower vertical position. This vertical dimensionality creates multiple parallel strands at different depths, improving nutrient distribution uniformity across the soil profile while maintaining emission-free application through direct soil incorporation.
4Manufacturing precision
If solid-containing slurry is distributed from a large opening into several smaller openings, then a finer distribution is achieved, but the sub-distribution regularly leads to blockages due to solids of varying sizes
Solution Approach 1:
The distribution device changes the parameter of outlet opening size by providing both first outlet openings and second outlet openings with different cross-sectional areas. This parameter variation allows the system to distribute slurry through multiple openings of appropriate sizes for the solid content, achieving finer distribution while minimizing blockage risk by not forcing all slurry through uniformly small openings.
