Reciprocating Sieve for Soil Impurity Removal and Ridge Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional field farming methods in fields with impurities require multiple steps and extensive time to remove impurities, making ridge formation and transplantation challenging, especially in clayey soils.
Innovation Solution
A ridge formation method and device that combines a tilling unit with a sieve instrument, where the sieve instrument moves reciprocally to separate finely-grained soil from impurities, allowing the soil to pass through a sieve mesh and accumulate on the ground, forming a ridge in a single operation, with optional vertical impact and elastic collision for enhanced sieving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional multi-step operation is used to remove impurities and form ridges, then impurity removal effectiveness is improved, but operational time and process complexity increase significantly
Solution Approach 1:
The patent combines the impurity removal function and ridge formation function into a single integrated device. The sieve unit with mesh structure performs both functions simultaneously: it separates impurities from soil while the separated soil accumulates to form ridges. This eliminates the need for separate sieving and ridge formation operations, reducing operational time while maintaining effectiveness.
Solution Approach 2:
The sieve unit serves multiple functions: it acts as both a separation device for removing impurities and a ridge formation device. The mesh structure simultaneously performs screening and shaping operations, allowing one component to fulfill multiple roles in the field preparation process.
2Reliability
If manual sieving operation is performed to remove impurities, then impurity removal effectiveness is improved, but device complexity and labor requirements increase
Solution Approach 1:
The patent merges the sieve unit with the ridge formation mechanism into a single integrated device. The mesh structure of the sieve unit is positioned such that separated soil naturally accumulates beneath it to form ridges, eliminating the need for separate ridge formation equipment and reducing overall device complexity.
3Manufacturing precision
If multiple separate operations are used for field preparation, then each operation can be optimized, but overall productivity decreases
Solution Approach 1:
The patent combines impurity removal and ridge formation into a single simultaneous operation using an integrated device. The sieve unit with mesh structure performs both functions in one pass through the field, doubling productivity compared to sequential operations while maintaining the effectiveness of each individual function.
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
This approach simplifies the process to a single operation, efficiently removing impurities and forming a soft ridge with improved soil granularity, facilitating easier seedling transplantation and growth by reducing operational time and labor.
Implementation Method 1
moving the sieve instrument in a reciprocating manner in a traveling direction to generate an impact on the received soil so that the soil is finely grained, and to separate the finely-grained soil from other impurities
Implementation Method 2
the finely-grained and separated soil is allowed to pass through a sieve mesh and fall onto a ground so that the falling soil is accumulated on the ground so as to form the ridge

AI summary
A ridge formation method includes the steps of: providing a sieve instrument immediately after a tilling unit configured to scrape soil to throw the soil backward while rotate a rotor having a plurality of soil scraping pieces to cause the tilling unit to travel, the sieve instrument configured to receive the thrown soil to perform a sieve operation; and moving the sieve instrument in a reciprocating manner in a traveling direction to generate an impact on the received soil so that the soil is finely grained, and to separate the finely-grained soil from other impurities, whereby the finely-grained and separated soil is allowed to pass through a sieve mesh and fall onto a ground so that the falling soil is accumulated on the ground so as to form the ridge substantially the same in width as the sieve instrument on the ground.
