Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting machines lack versatility in adjusting the shredding level of cut material, limiting their adaptability to various agricultural tasks and materials.
Innovation Solution
A cutting machine design featuring a movable end element and closure element that change positions to alter the cutting chamber's shape and size, allowing for adjustable shredding and discharge of materials, with options for different end elements like levelling rollers, refinement grids, and laminar elements, and adjustable fastening means for enhanced versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the cutting chamber has a fixed shape and size, then the machine structure is simple, but the versatility in handling different materials and tasks is limited
Solution Approach 1:
The end element and closure element are made movable between different positions (first and second positions) to dynamically change the cutting chamber's shape and size. This allows the same machine to handle different materials (grass, straw, stalks, shoots, wood) and perform different tasks by adjusting the chamber configuration, thereby resolving the contradiction between versatility and structural simplicity.
2Productivity
If the end element is positioned close to the rotor, then material discharge is facilitated, but the shredding duration is reduced limiting fine shredding capability
Solution Approach 1:
The end element can be positioned in a first position close to the rotor to facilitate material discharge and in a second position moved back from the rotor to increase shredding duration and achieve finer shredding. This dynamic positioning capability allows the machine to optimize between discharge efficiency and shredding fineness based on the specific task requirements.
3Manufacturing precision
If the closure element is positioned close to the end element, then the opening is closed to hold cut material longer for finer shredding, but material discharge is hindered
Solution Approach 1:
The closure element is movable between a first position close to the end element that closes the opening to hold cut material longer for finer shredding, and a second position remote from the end element that opens the discharge path. This dynamic adjustment allows optimization between shredding fineness and discharge efficiency based on operational needs.
4Adaptability or versatility
If multiple mounting positions are provided for the end element, then the number of possible chamber configurations is increased, but the device complexity increases
Solution Approach 1:
The side walls are provided with multiple discrete mounting positions (first, second, and third positions) for the end element, allowing selective attachment at different locations. This segmentation approach enables multiple chamber configurations for different applications while keeping each individual mounting position relatively simple, thus resolving the contradiction between versatility and complexity.

AI summary
Cutting machine comprising a body (2) having two lateral, juxtaposed sides (3, 4) and a hood (5) mounted between the sides (3, 4) for delimiting a cutting chamber (29), the chamber (29) having a rear opening (20) for discharging the cut material. The cutting machine includes a rotor (11) that is rotatably supported in the chamber (29) between the sides (3, 4), an end element (13) supported between the sides (3, 4) at the rear opening (20) of the chamber (29), and a closure element (15) supported between the sides (3, 4). The closure element (15) and the end element (13) are mounted on the sides (3, 4) so as to be movable between a first position, in which the end element (13) is moved back from the rotor (11) and the closure element (15) is oriented in a position close to the end element (13) so as to close the opening (20), at least in part, in order to hold the cut material in the chamber (29) for longer, and a second position, in which the end element (13) is moved closer to the rotor (11) than in the first position and the closure element (15) is oriented in a position remote from the end element (13) so as to substantially free the opening and to facilitate discharging of the cut material from the chamber (29).
