Swing Disc Spreader for Wide UAV Sowing With One Disc
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing spreading devices for unmanned aerial vehicles have complex structures, large volumes, and high costs due to the use of multiple spreading assemblies side by side.
Innovation Solution
A swing disc spreader with a rotatable swing disc and a swinging drive mechanism, which simplifies the structure, reduces volume, and lowers costs by using a single swing disc to spread materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If two spreading assemblies are arranged side by side to increase sowing width, then productivity is improved, but device complexity and volume increase
Solution Approach 1:
The patent employs a swing disc that rotates dynamically to spread material. The disc swings between left and right positions, using rotational motion to distribute material across the field. This dynamic single-disc design replaces static multi-assembly arrangements, achieving wide sowing coverage through motion rather than through multiple fixed spreading units.
Solution Approach 2:
The patent merges the functions of multiple spreading assemblies into a single integrated swing disc. The disc combines material storage, material discharge, and spreading functions in one component, eliminating the need for separate spreading assemblies while maintaining wide sowing width through its rotational swing motion.

3Productivity
If two spreading assemblies are arranged side by side to increase sowing width, then productivity is improved, but cost increases
Solution Approach 1:
The patent merges the functions of multiple spreading assemblies into a single integrated swing disc. The disc combines material storage, material discharge, and spreading functions in one component, eliminating the need for separate spreading assemblies while maintaining wide sowing width through its rotational swing motion.
Solution Approach 2:
The patent extracts and eliminates unnecessary components from traditional multi-assembly spreading devices. By removing separate spreading assemblies and retaining only the essential swing disc mechanism, the design reduces component count and manufacturing complexity while achieving the same sowing width through the disc's rotational swing action.

AI summary
A swing disc spreader includes a swing disc which is arranged to be rotatable; and a swing driving mechanism, which is in transmission connection to the swing disc and used for driving the swing disc to swing reciprocatingly, the swing disc being configured to be in contact with materials during a swinging process so as to spread the materials outwards. In the technical solution provided in the present application, the swing disc spreader can achieve the spreading operation of materials simply by using one swing disc, such that the swing disc spreader has a simpler structure, achieves a reduced overall size and a relatively uniform spreading width, thus reducing the cost.
