Seedling Transplanter Movable Insertion Member Swinging Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing seedling transplanting devices face difficulties in retaining the seedling and soil within the digging tube during extraction, especially in low-density or heavy soils, leading to potential dropping of the seedling.
Innovation Solution
A seedling transplanting device featuring a handheld rod with a fixed and movable insertion member assembly, where the driving assembly causes the movable insertion member to swing toward the fixed insertion member, reducing the distance between them to securely hold the soil and seedling, and a soil removal device for efficient extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a hollow tubular seedling digging tube with uniform diameter is used, then the structure is simple and easy to manufacture, but the seedling and soil may drop out during extraction in low-density or heavy soils
Solution Approach 1:
The insertion member is divided into a fixed insertion member and a movable insertion member that can swing relative to each other. This segmentation allows the device to transition between open and closed states, providing both easy insertion and secure retention without requiring a complex entirely new structure
Solution Approach 2:
The movable insertion member is designed to swing between an inserted position (parallel to fixed member) and an extracted position (convergent toward each other). This dynamic adjustment allows the device to adapt its internal volume and shape during different operational phases, ensuring reliable seedling retention during extraction while maintaining structural simplicity
2Reliability
If the movable insertion member swings toward the fixed insertion member during extraction, then the seedling and soil are securely held, but the device complexity increases
Solution Approach 1:
A driving assembly acts as an intermediary mechanism between the operator's manual input and the movable insertion member. This mediator converts simple rotational or linear motion into the required swinging motion, achieving reliable seedling retention without requiring the user to directly manipulate complex mechanisms
Solution Approach 2:
The driving assembly serves multiple functions: it controls the swinging motion of the movable insertion member, maintains the device structure during operation, and facilitates the transition between insertion and extraction phases. This multi-functionality reduces the need for separate dedicated components for each function
