Distribution Plate with Gradient Holes for Liquid Manure Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing distributors for liquid manure face increased clogging risks due to the higher viscosity and concentration of newer, more liquid manure types, as traditional solutions with rotating blades and perforated disks are inadequate for finely chopping solid particles through smaller distribution openings.
Innovation Solution
A distribution plate with a supply side having smaller openings than the discharge side, featuring a continuous connection with an increasing cross-sectional area, equipped with a moving cutting element to chop particles finely, preventing accumulation and clogging, and acting as a sieve or filter to ensure smooth flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If smaller through holes are used on spreading arms to reduce the amount of manure applied, then the quantity of substance applied is reduced, but the risk of clogging increases due to particle accumulation
Solution Approach 1:
The distribution plate is divided into multiple through-holes of different sizes, with larger holes positioned upstream and smaller holes downstream. This segmentation allows particles to be progressively filtered and transported without blocking any single small opening, resolving the contradiction between reducing manure quantity and preventing clogging.
Solution Approach 2:
Different regions of the distribution plate have different hole sizes tailored to their specific functions: larger holes at the inlet zone handle high-concentration manure with particles, while smaller holes at the outlet zone distribute the filtered liquid. This local differentiation enables the system to apply less manure overall while maintaining reliable flow without clogging.
2Manufacturing precision
If traditional rotating blades and perforated disks are used to chop solid particles, then particle size is reduced to some extent, but the chopping effectiveness is insufficient for highly concentrated liquid manure with pieces
Solution Approach 1:
The distribution plate performs preliminary particle size reduction through its progressive hole size design before the manure reaches the rotating blades. Large particles are naturally filtered and broken up as they pass through the graduated sequence of holes, preparing the manure for more effective chopping by subsequent blade action and preventing clogging upstream.
Solution Approach 2:
The distribution plate acts as an intermediary element between the manure inlet and the rotating blades. It pre-processes the highly concentrated liquid manure by filtering and partially chopping particles through its graduated hole structure, making the subsequent blade chopping more effective and preventing particles from accumulating before the blades.
3Reliability
If the distribution plate has smaller supply openings to reduce accumulation, then particle accumulation is reduced, but the surface area of the supply opening is limited
Solution Approach 1:
Instead of relying on a single large supply opening, the distribution plate uses multiple smaller through-holes arranged in a gradient pattern. This segmentation provides sufficient total opening area for manure flow while ensuring that no single opening is large enough to cause particle accumulation, thus preventing clogging.
Solution Approach 2:
The distribution plate transitions from a two-dimensional view of opening area to a three-dimensional progressive structure with holes of varying sizes at different depths and positions. This dimensional approach allows the system to maintain adequate total flow area while using smaller individual openings that prevent particle accumulation and clogging.

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 distribution plate effectively reduces the risk of clogging by ensuring that particles are chopped to a size that can pass through the smaller supply openings, maintaining flow and reducing the need for higher pressure, making it suitable for more viscous substances like the newer liquid manure.
