Movable Stator Comminuting Device for Dual-Depth Vegetable Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing comminuting devices require separate units or cutter exchanges for aboveground and belowground vegetable material processing, leading to high investment and operational costs, limited flexibility, and potential performance issues due to incomplete cutter sets.
Innovation Solution
A comminuting device with a stator that can be moved between positions relative to the rotor, allowing the same device to efficiently process both aboveground and belowground materials without cutter exchanges, by adjusting its configuration to accommodate different material depths and using curved counter elements and hexagonal openings for optimized comminution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate comminuting devices are used for aboveground and belowground vegetable material, then comminution performance is optimized, but investment costs and device complexity increase
Solution Approach 1:
The comminuting device is designed with a movable stator that can be positioned in different configurations to handle both aboveground and belowground vegetable material. The stator includes counter elements that can engage with the rotor in different positions, allowing the single device to perform multiple comminution functions without requiring separate specialized devices for each application.
Solution Approach 2:
The stator is made movable relative to the rotor, allowing dynamic reconfiguration of the comminuting chamber. The stator can be positioned to engage with different portions of the rotor circumference depending on whether aboveground or belowground material is being processed, enabling adaptive optimization of comminution performance for different material types.
2Reliability
If cutters are exchanged to adapt to different material types, then comminution performance is improved, but operational costs and time loss increase
Solution Approach 1:
Instead of exchanging static cutters, the invention employs a movable stator that can be repositioned relative to the rotor. This dynamic configuration allows the same cutter set to be used for different material types by simply adjusting the stator position, eliminating the time-consuming process of cutter exchange while maintaining optimized comminution performance.
Solution Approach 2:
The invention changes the operational parameter of the comminuting device by varying the stator position relative to the rotor rather than changing the physical cutters themselves. This parameter adjustment allows adaptation to different vegetable material types (aboveground vs. belowground) without requiring physical exchange of cutting elements, thereby reducing operational time and costs.
3Adaptability or versatility
If detachable cutters are used for rotor modification, then adaptability is improved, but reliability and performance suffer due to incomplete cutter sets
Solution Approach 1:
The movable stator with counter elements provides a universal solution that works with the complete cutter set already installed on the rotor. By repositioning the stator rather than removing cutters, the system maintains full cutter sets in place while achieving adaptability through stator configuration changes, thereby preserving reliability and performance.
4Power
If narrow cutters are used for belowground material, then device overload is prevented, but aboveground comminution performance deteriorates
Solution Approach 1:
The movable stator allows the system to dynamically adjust the comminuting chamber configuration based on material type. When processing belowground material, the stator is positioned to work with narrow cutters to prevent overload. When processing aboveground material, the stator repositioning enables the same narrow cutters to achieve effective comminution through optimized engagement geometry, thus maintaining power limits while preserving performance across different applications.

AI summary
The invention relates to a comminuting device (1) for comminuting vegetable material (8, 18). The comminuting device has a frame (2) which can be coupled to a vehicle (4) by means of a coupling element (20), a rotor (5) which is rotatably suspended in the frame (2) and provided with treatment elements (6), and a stator (7) which is attached to the frame (2) and provided with counter elements (13). In an operating position, this stator (7) is situated near a part of the circumference of the rotor (5) so as to leave clear another part of the circumference of the rotor (5) to which organic material (8) to be comminuted can be supplied. The vegetable material (8) is comminuted by rotating the treatment elements (6) and the counter elements (13) with respect to one another. The invention also relates to methods for comminuting vegetable material (8, 18) which is aboveground and/or belowground.
