Removable Lateral Plates for Shredder Tool Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing protection devices for shredding and cutting tools, particularly those used for biomass, are expensive and irreversible, making them difficult to interchange and adapt for different cutting depths and lengths, and do not effectively manage centrifugal forces or ensure uniform shredding.
Innovation Solution
A protection device for tool-holders featuring a tool-holder rotor with a seat that allows for removable lateral projections and plates, which are connected via geometric coupling to limit cutting depth and absorb centrifugal forces, enabling quick interchangeability and uniform shredding by directing material flow effectively towards the cutting tool.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protection devices are securely fixed onto the rotor for specific shredding/cutting applications, then reliability and protection are improved, but adaptability and ease of interchangeability deteriorate
Solution Approach 1:
The protection device is divided into modular components: a base element that attaches to the rotor and removable plates that can be easily exchanged. This segmentation allows the protective function to be maintained while enabling quick adaptation for different shredding applications by simply changing the plate component.
Solution Approach 2:
The protection device transitions from a static, permanently fixed design to a dynamic, interchangeable system. The removable plates can be quickly attached and detached from the base element, allowing the system to adapt its configuration based on the specific shredding or cutting application requirements.
2Reliability
If protection devices are custom-designed for specific cutting tools and applications, then protection effectiveness is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The base element is designed as a universal component that can accommodate multiple different plate configurations for various shredding and cutting applications. This multi-functional design allows a single base element to serve multiple purposes, reducing the need for custom-designed protection devices for each specific application.
Solution Approach 2:
Instead of designing entirely custom protection devices for each application, the invention uses a standardized base element that can be paired with different removable plates. This approach creates a template or copyable foundation that simplifies design and manufacturing while still providing application-specific protection through the interchangeable plates.
3Reliability
If protection devices are permanently fixed onto the rotor, then reliability is improved, but ease of operation and quick adaptation deteriorate
Solution Approach 1:
The protection device is segmented into a permanently fixed base element and removable plates. The base element provides secure, reliable attachment to the rotor, while the removable plates can be easily mounted and dismounted without affecting the security of the overall assembly.
Solution Approach 2:
The base element is pre-designed and pre-attached to the rotor with appropriate fixing mechanisms in place before the removable plates are installed. This preliminary preparation ensures that when the plates need to be changed, the secure foundation is already in place, allowing for quick operation without compromising reliability.

AI summary
A protection device for tools for cutters and shredders and the like, arranged on a tool-holder seat for a tool-holder rotor rotatable about the axis of the rotor, said tool being housed in a seat arranged on the tool-bolder rotor, and formed by a first surface arranged at the front in the cutting direction and a second surface onto which the tool is fixed with its opposite surface to the cutting direction, the tool having a body that has a front surface in the rotation direction of the rotor, and a rear surface opposing the front surface. The tool and/or the seat having lateral projections and a protection device is dismountable connected to the seat of the tool, laterally as a protection for the tool and the plates being arranged partially between the lateral projections, of the tool and/or the seat of the tool, and the tool-holder rotor.
