Agricultural Soil Roller with Articulated Bracket Segments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural ground rollers tend to be unstable on sloping surfaces and have an insufficient crumbling effect, particularly in certain soil conditions, which affects soil filtration, drainage, and respiration.
Innovation Solution
The ground roller features bracket segments with non-cylindrical, conically contoured or inclined outer peripheral surfaces, allowing deeper penetration in some areas and preventing slipping, along with two-sided articulation or fastening for enhanced stability and crumbling, and alternating conicity to improve directional stability and crumbling performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If bracket segments are designed with conically contoured or inclined outer peripheral surfaces, then the crumbling effect is improved and penetration depth increases, but the roller may experience lateral pull and instability on slopes
Solution Approach 1:
The bracket segments are designed with asymmetric conical or inclined outer peripheral surfaces, where one side wall protrudes further than the other, creating different rolling diameters. This asymmetry enables deeper penetration on one side to improve the crumbling effect while the alternating arrangement of such segments balances the lateral forces to maintain driving stability.
Solution Approach 2:
Different regions of the bracket segments have different geometric properties - the conical or inclined surfaces create localized variations in penetration depth and pressing force. This local quality variation allows the roller to achieve both deep consolidation and effective crumbling in different areas, while the alternating pattern ensures overall stability.
2Strength
If bracket segments are rigidly fastened at both ends, then structural strength and crushing performance improve, but flexibility and adaptability to uneven terrain decrease
Solution Approach 1:
The bracket segments are designed with articulated connections at both ends, allowing them to pivot and adjust their orientation dynamically. This dynamic capability enables the rigidly fastened segments to maintain structural strength for crushing while adapting their angle and position to accommodate uneven terrain, combining rigidity with flexibility.
3Object-generated harmful factors
If rolling bodies are composed of arcuate bracket segments with recesses, then soil filtration and drainage effects improve, but the overall soil consolidation strength decreases
Solution Approach 1:
The rolling bodies are segmented into multiple arcuate bracket segments with recesses between them. This segmentation creates channels for water drainage and air filtration while maintaining sufficient contact area for soil consolidation. The segmented structure allows the roller to perform both consolidation and drainage functions simultaneously without compromising overall effectiveness.
Applied Scientific Principles
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 enhances the crumbling effect, maintains soil filtration and drainage, and stabilizes the roller on slopes by ensuring deeper penetration and reduced lateral pull, thereby improving soil respiration and overall soil consolidation.
Implementation Method 1
the bracket segments no longer rest evenly on the ground, but rather digs deeper into the ground in some areas and weaker in some areas pushes
Implementation Method 2
one side wall of the hoop segment is higher than the other side wall or one side wall defines a larger rolling diameter than the other side wall, so that the hoop segment presses deeper into the ground on the side of the side wall that protrudes further
Implementation Method 3
the spring clip-like clip segments are only attached at one end in the manner of a cantilever, while the other end protrudes freely, so that the clip segment is given elastic resilience

AI summary
The present invention relates to an agricultural soil roller with a roller body 2 comprising a plurality of adjacent rolling elements 3, wherein the rolling elements 3 each comprise several arcuate bracket segments 9 which together form the rolling surface of the respective rolling element 3. It is proposed that the rolling surface of the rolling elements 3 formed by the bracket segments 9 no longer be cylindrical, but rather have a contour deviating from the cylindrical shape, so that a bracket segment no longer rests uniformly on the ground, but presses into the ground more strongly in some areas and less strongly in others.
