Pasture Grass Compression Tube for Accurate Quality Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing quality determination devices for pasture grass face challenges in accurately determining quality due to diffused reflection caused by gaps between sparse grass, leading to inaccurate measurements.
Innovation Solution
A work vehicle equipped with a quality determination device that includes a grass sending tube and a grass taking section to compress pasture grass, reducing gaps and enabling accurate quality determination by minimizing diffused reflection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pasture grass is determined in a sparse state with gaps, then the determination process is simple, but diffused reflection occurs preventing accurate quality determination
Solution Approach 1:
The system performs preliminary compression of the pasture grass using a compression section before the quality determination. This pre-compression action removes gaps and aligns the grass uniformly, creating optimal conditions for light transmission and eliminating diffused reflection before the measurement process begins.
Solution Approach 2:
The patent introduces a light guide as an intermediary component that directs and concentrates light through the compressed pasture grass. The light guide acts as a mediator between the light source and the grass sample, ensuring uniform light distribution and enabling accurate spectral analysis by eliminating the effect of gaps and irregular surfaces.
2Measurement precision
If pasture grass is compressed to reduce gaps, then light transmission improves for accurate determination, but device complexity increases
Solution Approach 1:
The compression function and quality determination function are merged into a single integrated device. The compression section is directly coupled with the determination section, allowing the grass to be compressed and measured in one continuous process without requiring separate equipment or manual intervention, thereby reducing overall system complexity.
Solution Approach 2:
The compression mechanism is designed to be self-regulating, using the movement of the work vehicle itself to drive the compression process. As the vehicle moves forward, the grass is automatically fed into the compression section and compressed without requiring additional power sources or complex control systems, making the device simple and self-sufficient.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for high-accuracy quality determination of pasture grass by compressing it within the grass sending tube, suppressing diffused reflection, and ensuring uniform mixing of grass for consistent quality assessment.
Implementation Method 1
determines water content by irradiating light onto the pasture grass and then effecting a spectroscopic analysis of reflected light
Implementation Method 2
the pasture grass present in a sparse state will be gradually compressed inside the grass sending pipe
