Self-Propelled Irrigation Device with Rotating Support Frame
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-propelled irrigation devices face limitations in dispensing output due to the length of the dispensing line, which restricts working width and efficiency, while also causing soil erosion and superficial water run-off.
Innovation Solution
A self-propelled irrigation device with a foldable dispensing line and support frame assembly, allowing for a significantly longer dispensing line without the need for a self-supporting design, and enabling uniform wetting of large land areas while avoiding soil erosion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the length of the dispensing line is increased to achieve larger working width, then the productivity is improved, but the self-supporting tube material sags and scrapes along the ground blocking rotation
Solution Approach 1:
A support frame assembly acts as an intermediary structure between the hose drum and the dispensing line. This support frame provides mechanical support for the dispensing line at multiple points, preventing sagging and ground contact while maintaining the ability to rotate. The support frame includes support legs that can be adjusted to provide stable support without interfering with the rotational movement of the dispensing line.
2Extent of automation
If the first irrigator uses water energy for drum drive, then the device can operate autonomously, but the range of trajectory of exiting water is limited
Solution Approach 1:
The irrigation system is segmented into two independent irrigators: a first irrigator for driving the hose drum using water energy, and a second irrigator for achieving large working width with extended water trajectory. This segmentation allows each irrigator to be optimized for its specific function without compromising the other.
Solution Approach 2:
The water supply system serves multiple functions: it provides water for the first irrigator to drive the drum, and simultaneously provides water for the second irrigator to achieve large working width irrigation. The system universally uses water energy for both propulsion and irrigation purposes.
3Productivity
If the second irrigator operates at high water pressure to achieve large working width, then the productivity is improved, but the energy consumption increases
Solution Approach 1:
The support frame assembly is designed to be dynamically adjustable, allowing the system to adapt to different working conditions. The support legs can be adjusted in length and position to optimize the dispensing line configuration for different working widths, enabling efficient operation without requiring maximum water pressure for all conditions.
