Tapered Disc Mounting Assembly for Easy Tillage Disc Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc mounting arrangements in vertical tillage implements are prone to debris lodgment, making maintenance and replacement difficult due to soil and residue accumulation, leading to operational inefficiencies.
Innovation Solution
A disc mounting assembly featuring a tapered shaft section and socket configuration, secured by a retaining bolt, allows for secure attachment and easy replacement of tillage discs, facilitating quick maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a traditional disc mounting arrangement is used, then the disc can be securely mounted on the tillage implement, but debris and residue accumulate around the mounting mechanism making maintenance and replacement difficult
Solution Approach 1:
The mounting assembly is divided into separate components: a mounting body attached to the tillage implement, a removable shaft with tapered end, and a disc hub. This segmentation allows the shaft to be easily detached and replaced without removing the entire mounting assembly, facilitating maintenance while preventing debris accumulation in tight spaces.
Solution Approach 2:
The shaft is extracted as a separate removable component from the mounting body. The tapered shaft section can be easily removed from the tapered socket section, allowing operators to access and replace the shaft without dealing with the entire mounting mechanism, thereby eliminating debris lodgment issues and simplifying maintenance.
2Reliability
If a secure mounting mechanism is used to firmly attach the disc, then the disc remains stable during operation, but the mechanism becomes complex and difficult to maintain
Solution Approach 1:
The mounting mechanism uses a tapered geometry parameter change to achieve secure attachment. The tapered shaft section (with its specific angle and dimensions) mates with the corresponding tapered socket section, creating a friction-fit connection that is both simple in design and reliable in operation, eliminating the need for complex fastening mechanisms.
3Strength
If the shaft is firmly secured in the mounting body, then the disc operates stably, but replacement of the shaft requires disassembly of the entire mounting mechanism
Solution Approach 1:
The shaft is designed with a tapered section that预先 (in advance) facilitates easy insertion and removal. The tapered geometry allows the shaft to be quickly pushed into and pulled out of the mounting body without requiring complex disassembly procedures, reducing replacement time while maintaining secure operation during use.
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 disc mounting assembly allows for secure attachment and easy replacement of the shaft, enabling quick maintenance and replacement of the shaft, while also ensuring the effectiveness of the technical solution, the shaft, while also ensuring the effectiveness of the technical solution. The shaft, while also ensuring the effectiveness of the technical solution, the shaft to be readily replaced in the event that maintenance is required to the shaft or the disc hub rotatably supported on the shaft.
Implementation Method 1
The shaft includes a tapered shaft section adjacent the first end of the shaft in which the tapered shaft section is tapered to be reduced in diameter towards the first end of the shaft; and wherein the socket includes a tapered socket section receiving the tapered shaft section matingly therein
Implementation Method 2
The tapered shaft section received within the tapered socket section allows the shaft of the tillage disc to be firmly secured relative disc supporting arm

AI summary
In a tillage implement for being towed by an agricultural tractor across ground to be towed and having a main frame supporting a plurality of tillage units thereon in which each tillage unit includes a disc supporting arm mounted on the main frame, disc mounting assemblies support respective tillage discs on the disc supporting arms. Each assembly includes a mounting body forming a socket therein and a shaft partly received within the socket so as to support a tillage disc on a hub rotatable on a portion of the shaft protruding from the mounting body. The shaft includes a tapered shaft section received within a tapered socket section in the socket of the mounting body to securely and releasably mount the shaft relative to the mounting body.
