Lateral Stem Displacement Device for Agricultural Winder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for collecting and processing continuous tablecloths of vegetable stems, such as flax or hemp, often result in stem crushing, dust accumulation, and difficulty in maneuvering, especially in tight spaces or near obstacles.
Innovation Solution
A device attached to a motorized machine that laterally displaces the continuous tablecloth of vegetable stems before collection, positioning it between the wheels of the machine to prevent crushing and allow for standard roller use, while also facilitating maneuverability and dust reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a standard winder is used mounted in the axis of the motorized machine, then the device complexity is reduced, but the plant stems are crushed by the wheels of the motorized machine
Solution Approach 1:
The device performs preliminary lateral displacement of the continuous sheet of plant stems before the motorized machine passes over it. By moving the sheet aside in advance and positioning it between the wheels, the invention prevents stem crushing while allowing the use of a standard axially-mounted winder, thus resolving the contradiction between device simplicity and prevention of harmful effects.
2Object-affected harmful factors
If an offset winder is used to prevent stem crushing, then the stem crushing is avoided, but the device complexity and maneuvering difficulty increase
Solution Approach 1:
Instead of using a complex offset winder, the invention applies preliminary action by laterally displacing the plant stems before collection. This allows a simple standard winder to be used in the axial position while still preventing stem crushing, thereby avoiding the device complexity and maneuvering issues associated with offset winders.
3Object-affected harmful factors
If an offset winder is used to prevent stem crushing, then the stem crushing is avoided, but the ease of operation deteriorates due to maneuvering difficulties
Solution Approach 1:
The lateral displacement device performs preliminary action by moving the plant stems aside before the motorized machine needs to pass. This eliminates the need for complex offset winder maneuvers, allowing the motorized machine to operate in its standard position while still preventing stem crushing, thus significantly improving ease of operation.
4Device complexity
If the lateral offset of offset winders is limited, then the device complexity is reduced, but the effectiveness in preventing wheel contact with the sheet decreases
Solution Approach 1:
The invention achieves reliable protection from wheel contact by performing preliminary lateral displacement of the plant stems to a sufficient distance. This ensures that when the motorized machine passes over, its wheels do not contact the stems, while allowing the winder to remain in the simple axial position without requiring limited lateral offset.
5Device complexity
If offset winders are used with single-sided lateral offset, then the device complexity is reduced, but the ease of operation deteriorates at field edges
Solution Approach 1:
The lateral displacement device is designed to be dynamic and adaptable, capable of adjusting its lateral displacement direction and magnitude based on operating conditions. This allows the device to effectively handle field edge scenarios by displacing stems away from obstacles or hedges, improving ease of operation at field edges while maintaining a simple device configuration.
