Agricultural Spreader Adapting Distribution to Plant Rows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural distribution devices struggle to adapt the spreading of granular material in areas where the row structure on the agricultural land is interrupted, leading to inefficiencies and waste of fertilizers.
Innovation Solution
The method involves using a combination of plant row detection and adjustable distribution patterns to switch between row-wise and area-wise spreading, allowing for localized adaptation in areas with row interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If granular material is spread using a fixed distribution pattern across the entire agricultural land, then the spreading process is simple and consistent, but granular material is wasted in areas where plant rows are interrupted or absent
Solution Approach 1:
The distribution pattern of the granular material is made dynamically adjustable based on real-time detection of plant rows. The system transitions from a fixed distribution pattern to a variable one that adapts to the presence or absence of plant rows, thereby preventing material waste in areas where rows are interrupted while maintaining spreading simplicity through automated control.
Solution Approach 2:
The system changes the distribution parameters (such as spreading width, material flow rate, or nozzle positioning) based on the detected plant row configuration. When plant rows are detected, the system adjusts the distribution pattern to concentrate granular material along the rows; when rows are interrupted or absent, the system modifies the parameters to reduce or stop spreading, thus eliminating waste.
2Manufacturing precision
If granular material is spread row-wise in areas with plant rows, then nutrient distribution is optimized for crops, but the spreading system becomes more complex requiring detection and adaptation capabilities
Solution Approach 1:
The system incorporates detection devices that continuously monitor the agricultural land for plant row presence and provide feedback to the distribution system. Based on this feedback, the system automatically adjusts the granular material distribution pattern to match the detected row configuration, achieving precise nutrient delivery without requiring complex manual intervention.
Solution Approach 2:
The agricultural land is segmented into different zones based on plant row detection (areas with rows, areas without rows, headland regions). The distribution system then applies different spreading strategies to each segment, allowing precise row-wise distribution in crop areas while simplifying or stopping distribution in non-row areas, thereby achieving precision without uniform complexity throughout the entire field.
3Loss of substance
If the distribution pattern is adapted locally in areas with row interruptions, then granular material is saved, but the control system becomes more complex
Solution Approach 1:
The distribution system is designed to automatically detect plant rows and adjust its own distribution pattern without external intervention. The system uses onboard sensors to monitor the field conditions and self-regulates the granular material flow, thereby achieving fertilizer savings through automated adaptation rather than requiring complex external control systems.

AI summary
A method of spreading granular material by an agricultural distribution device includes the steps of: spreading granular material onto an agricultural land by a plurality of distribution elements arranged on a distribution linkage of the agricultural distribution device, and detecting plant rows on the agricultural land during the spreading of the granular material, wherein the granular material is spread in row areas of the agricultural land having plant rows by at least one distribution element with a first distribution pattern and is spread in row-free areas of the agricultural land not having plant rows by at least one distribution element with a second distribution pattern.
