Cap Bracket and Spacer Layout for Cultivator Disc Arm Drift
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The lateral shifting of ground engaging tools due to torsion element deformation from lateral forces during cultivation, especially in deep tilling practices, disrupts the uniformity of the cutting profile and spacing of cultivator discs.
Innovation Solution
A cap bracket design with extended portions and spacers to stabilize the ground engaging tools, preventing lateral drift by allowing rotational movement while maintaining consistent spacing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If torsion elements are used to allow disc tripping when hitting obstacles, then the cultivator can handle uneven terrain and obstacles, but lateral forces cause deformation of torsion elements which leads to lateral drift of disc arms
Solution Approach 1:
The cap bracket with extended portions acts as an intermediary component between the disc arm and the mounting bar. The extended portions engage with corresponding features on adjacent cap brackets to form a lateral support system that prevents drift while allowing the torsion elements to function for vertical tripping motion.
2Power
If disc arms are clamped tightly around torsion elements to generate operating torque, then sufficient cutting force is generated, but lateral forces from soil engagement cause deformation and lateral shifting
Solution Approach 1:
The support structure is segmented into individual cap brackets, each with extended portions that provide lateral support. This segmentation allows each disc arm to be supported independently while maintaining the overall stability of the cultivator frame.
3Productivity
If high demand tripping cycles occur in deep tilling, then effective deep soil cultivation is achieved, but lateral forces on torsion elements are exacerbated causing increased lateral drift
Solution Approach 1:
The cap bracket design merges multiple functions: it provides the mounting interface for the disc arm, incorporates extended portions for lateral support, and maintains spacing control. This consolidation of functions ensures that lateral drift is prevented while maintaining the productivity benefits of deep tilling.
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
Maintains consistent spacing and cutting profile of cultivator discs, ensuring uniform soil agitation and seed bed preparation.
Implementation Method 1
The torsion elements are typically formed of an elastic material, which can be deformed by this lateral force. This deformation of the torsion elements by the lateral force can cause the disc arm where it is connected to the cultivator to shift laterally.

AI summary
A cap bracket and spacer for connecting a ground engaging tool to a mounting bar of a cultivator is provided. The cap bracket can include a first member having a first side and a second side, and a second member having a first side and a second side. The second member can be joined at the second side to the second side of the first member with a peak formed where the second side of the first member is joined at the second side of the second member and a first extended portion can be provided on a first end of the cap bracket at the peak. The spacer can include a first connection flange, a second connection flange, and a spacer member extending upwards from the first connection flange and the second connection flange to define a contact surface.
