Soil Cultivation Share With Twisted Guide Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The abrupt change in direction of the guide plate in soil working tools leads to clogging issues as soil and plant residues get stuck in the region of the end sections bent backwards, causing constipation.
Innovation Solution
The guide plate is designed with a twisted contact element that fills the gap between the rear side of the guide plate and the tool holder, ensuring a continuous transition and inclined surface to guide residues past without blockage, enhancing contact and fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guide plate is bent backwards to achieve secure lateral guidance and fixing, then the fixation reliability is improved, but the clogging risk increases due to abrupt direction change causing soil and plant residues to get stuck
Solution Approach 1:
Instead of bending the guide plate backwards to achieve fixation, the patent inverts the approach by using a twisted guide plate with a contact element that fills the gap between the guide plate and tool holder. This inversion eliminates the abrupt direction change that causes clogging while maintaining secure lateral guidance through the twisted geometry and contact element design.
Solution Approach 2:
The patent introduces a contact element as an intermediary component that fills the gap between the guide plate and tool holder. This contact element with its inclined surface acts as a mediator that guides soil and plant residues smoothly from the guide plate to the tool holder, preventing clogging while ensuring secure fixation.
2Manufacturing precision
If the guide plate is bent backwards to improve lateral guidance, then the guidance precision is improved, but the soil and plant residues accumulate in the bent region causing constipation
Solution Approach 1:
The patent applies curvature by designing the guide plate with a twisted geometry instead of an abrupt bend. The twisted guide plate creates a smooth curved transition that maintains precise lateral guidance while allowing soil and plant residues to flow through without accumulation, thus preserving operational efficiency.
Solution Approach 2:
The patent changes the geometric parameters of the guide plate from an abrupt bent configuration to a twisted configuration with a contact element. This parameter change transforms the sharp angle into a gradual transition, maintaining guidance precision while eliminating the accumulation zone that reduces productivity.
3Object-affected harmful factors
If the contact element is designed with an inclined surface to guide residues past, then the clogging resistance is improved, but the structural complexity increases
Solution Approach 1:
The patent merges the contact element with the guide plate structure, integrating the inclined surface directly into the guide plate design. This merging reduces structural complexity by eliminating separate components while maintaining the clogging resistance function through the twisted geometry and integrated contact surface.

AI summary
Soil cultivation share, in particular cultivator share 1 with a guide plate 5 adjoining the share tip 7, wherein the share tip and/or the guide plate comprises at least one hole 2 which is intended to receive a fastening element for attachment to a tool holder 3, wherein the guide plate has a substantially concave surface in the direction of travel, wherein a contact element 15 for contact with the tool holder is located on the upper end section in the direction of the rear side 12 of the guide plate.In order to avoid, or at least significantly reduce, the risk of clogging in the area of the contact element of the guide plate on the tool holder, it is provided that the contact element fills the gap 16 between the back of the guide plate and the side surface 17 of the tool holder, and that the contact element transitions from the upper side 18 obliquely to the rear side of the guide plate with a continuous transition into the rear side of the guide plate.
