Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for treating stony farmland do not effectively separate coarse and small particles, leading to damage during harvesting and reduced crop yield, as they fail to create a targeted, stone-free planting zone that optimally supports plant growth and reduces tool wear.
Innovation Solution
A method and device that use a separating device with a conveying path to sort particles into defined collection zones below a stone-free wear layer, ensuring coarse particles are deposited in a linear collection zone, which reduces tool wear and enhances soil structure for planting and harvesting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If existing separation methods are used, then soil separation is performed, but coarse and small particles are not effectively separated, leading to damage during harvesting and reduced crop yield
Solution Approach 1:
The separation device divides the soil mixture into distinct fractions based on particle size, creating separate streams for coarse particles and small particles. This segmentation allows precise control over where each particle type is deposited, achieving effective separation that prevents harvesting damage and improves crop yield.
Solution Approach 2:
The invention applies different treatment zones with specific functions: one zone for collecting coarse particles and another for small particles. Each zone has optimized characteristics for its specific particle type, enabling precise local separation and deposition that enhances overall separation precision and protects crops.
2Productivity
If stones are not effectively removed, then harvesting can proceed, but tool wear increases and soil structure is compromised
Solution Approach 1:
The separation device extracts and removes coarse particles and stones from the soil mixture before harvesting. By taking out these harmful elements in advance, the invention protects harvesting tools from wear and damage while maintaining harvesting capability and productivity.
3Device complexity
If soil is not properly layered, then processing is simpler, but plant growth is hindered due to lack of optimal soil structure
Solution Approach 1:
The separation device performs preliminary sorting and layering of soil particles before planting. Coarse particles are deposited in one layer while small particles form another layer, creating an optimized soil structure in advance. This preliminary action simplifies subsequent planting operations while providing reliable soil conditions for plant growth.

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 solution achieves a stone-free planting zone with reduced tool wear and optimal soil structure, improving crop yield and productivity by effectively separating and positioning coarse and small particles, thereby minimizing damage during harvesting.
Implementation Method 1
This gravity-driven sorting process is designed so that, in the direction of travel, at least the coarse particles are transferred forward into a mixed layer deposited across the width of the field surface
Implementation Method 2
at least a fraction of the sortable particles are deposited in at least one collection zone, which is essentially linear and extends below the topsoil

AI summary
In a method for treating stony arable soils, a mixture of stony arable soil, collected as a soil layer across the working width, is conveyed along an ascending conveyor to a separation device positioned at a distance above a field area. Within this device, the mixture is transferred along at least one separation section. The process is controlled such that, by means of at least phased deflection of portions of the mixture, different mixture fractions in the form of coarse, small, and fine particles are sorted out sequentially or simultaneously. According to the invention, at least one fraction of the sortable particles is deposited in at least one collection zone that is essentially linear and extends below the topsoil.For this purpose, at least one separation section of the separation device has a discharge unit with which at least one particle fraction selectable from the mixture can be deposited in at least one linear collection zone running below the usable layer.
