Combined Soil Cultivator and Stone Separator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil cultivators and stone/clod separators require multiple passes and operations to achieve fine soil conditions, leading to increased power consumption, soil damage, and inefficiency in separating clods and stones.
Innovation Solution
A combined soil cultivator and stone/clod separator with multiple sieving conveyors and a soil crumbling assembly, where oversized material is broken down in a single pass, reducing the need for separate operations and enhancing the effectiveness of sieving and crumbling actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple passes and separate operations of cultivator/separator are used, then fine soil conditions free of clods and stones are achieved, but power consumption increases and soil structure is damaged
Solution Approach 1:
The patent combines the soil cultivating function and stone/clod separating function into a single integrated machine that performs both operations simultaneously in one pass. The cultivating assembly breaks down clods while the sieving conveyor separates stones and oversized material, eliminating the need for multiple separate passes and thereby reducing power consumption and soil damage.
2Manufacturing precision
If multiple passes and separate operations are used, then clod-free soil conditions are achieved, but the number of operations increases reducing efficiency
Solution Approach 1:
The machine merges soil cultivation and stone separation into a single simultaneous operation. The cultivating assembly processes clods while the sieving conveyor operates concurrently to remove stones, achieving clod-free conditions in one pass rather than requiring multiple sequential operations, thereby significantly improving operational speed and productivity.
3Manufacturing precision
If multiple separate operations are used, then thorough soil preparation is achieved, but overall time required increases
Solution Approach 1:
The patent integrates multiple soil preparation functions into a single machine that operates simultaneously. The cultivating assembly breaks down clods while the sieving conveyor removes stones and oversized material in one continuous operation, achieving thorough soil preparation without the time loss associated with multiple separate passes and operations.
4Manufacturing precision
If separate stone/clod separating and cultivating operations are performed, then effective separation is achieved, but the number of passes required increases
Solution Approach 1:
The patent combines separate stone/clod separation and cultivating operations into a single integrated machine. The cultivating assembly processes soil and clods while the sieving conveyor simultaneously separates stones and oversized material, achieving effective separation in one operation rather than requiring multiple separate passes, thereby reducing operational complexity.

AI summary
The invention relates to a combined soil cultivator and stone/clod separator, a soil cultivator, a stone and clod separator, and to a method of cultivating soil and separating stones/clods. In an embodiment of the invention, a combined soil cultivator and stone/clod separator (7) is disclosed which comprises a digging device (1), a first soil sieving conveyor (3), a soil crumbling assembly (4) and a further soil sieving conveyor (5). The digging device (1) is arranged to dig up material and to transfer the material rearwardly, relative to a direction of travel, to the first soil sieving conveyor (3). The soil crumbling assembly (4) is positioned downstream of the first soil sieving conveyor (3), for receiving material from the first soil sieving conveyor (3). The further soil sieving conveyor (5) is positioned to receive substantially all of the material passing down through the at least one soil crumbling assembly (4). The soil cultivator and stone/clod separator (7) exerts a combined cultivating and stone/clod separating action on soil in a single pass across the surface of a field or the like.
