Soil Working Tool Separate Seats Cutting Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil tillage tools, such as goosefoot shares, face challenges in wear resistance due to the complex and costly process of positioning hard metal cutting inserts, which can interfere with each other during use, leading to reduced tool longevity.
Innovation Solution
The soil working tool features separate seats for the first cutting elements, allowing for independent positioning and easy soldering, with the cutting elements being set back from each other to prevent mutual influence during use, and utilizing hard metal cutting plates with tungsten carbide and titanium carbide for enhanced durability, along with coatings for increased wear resistance.

1Duration of action of stationary object
If hard metal cutting inserts are used to increase wear resistance, then the service life is extended, but the manufacturing complexity and cost increase due to precise positioning requirements
Solution Approach 1:
The base body is divided into multiple separate seats, each capable of independently receiving and positioning a single cutting insert. This segmentation allows each insert to be positioned and soldered independently, eliminating the need for complex precise positioning of multiple inserts relative to each other, while still achieving the desired wear resistance through the use of hard metal material in each seat.
2Productivity
If cutting elements are positioned close together for continuous cutting, then cutting performance is improved, but mutual interference and force loading between elements occurs
Solution Approach 1:
The cutting elements are extracted from a continuous configuration and positioned in separate, isolated seats with spacing between them. This extraction prevents mutual interference and force loading between adjacent cutting elements, while the continuous cutting performance is maintained through the sequential arrangement of multiple separated seats along the cutting path, each contributing to the overall cutting function.
3Productivity
If multiple cutting elements are soldered together in contact, then cutting performance is achieved, but the positioning process becomes very complex
Solution Approach 1:
The manufacturing process is segmented into independent positioning and soldering operations for each cutting element in its respective seat. Each cutting element can be positioned and secured independently without requiring precise coordination with other elements, significantly simplifying the overall manufacturing process while maintaining the cutting performance through the collective function of all seated elements.
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
This design simplifies manufacturing, enhances wear resistance, and extends the tool's service life by ensuring continuous cutting performance and effective weed separation without premature wear, while minimizing the need for frequent replacements.
Implementation Method 1
The hard metal can be a hard metal which, in addition to a customary binder metal made of cobalt, iron and/or nickel, has tungsten carbide to the extent of 6 percent by weight (% by weight) to 12% by weight. The tungsten carbide can optionally be partially replaced by up to 25% by weight of titanium carbide.
Implementation Method 2
The first cutting elements in general and the cutting plates in particular can be coated, which increases wear resistance. Preferred coatings are coatings of an alumina or an aluminum titanium nitride.
Implementation Method 3
If hard metal elements are provided on soil working tools for a cutting engagement, they are soldered onto a base body.
