Trailered Grain Reaper With Segmented Gathering Rollers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current grain harvesting and cleaning machines are costly, prone to wear, and require frequent maintenance due to the aggressive nature of the harvesting process, which includes dealing with plants, stones, and branches, and the vibrating sieve system is not adequately resistant to premature wastage.
Innovation Solution
A trailered reaper with a double gathering roller system featuring axially aligned rollers with triangular plates and a star-like bore for enhanced grip, combined with a reverse thread system to concentrate and separate materials, and a vibrating sieve for grain separation, along with hydraulic elevators for efficient unloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional gathering rollers are used, then the machine can harvest plants, but the rollers wear out easily due to impact with stones, land, and branches
Solution Approach 1:
The gathering roller is divided into multiple sections, each with different grip characteristics. The first section has strong grips for initial engagement, while subsequent sections have progressively weaker grips, allowing the roller to handle various plant types and obstacles without failing
Solution Approach 2:
Different portions of the gathering roller have different properties - the grips are arranged to provide strong initial grip strength followed by progressively weaker grips, and the roller has variable cross-sectional thickness to optimize both strength and flexibility for handling obstacles
2Productivity
If a single operator performs both harvesting and cleaning operations, then productivity increases, but the complexity of operating multiple sets increases
Solution Approach 1:
The patent combines the harvesting and cleaning operations into a single integrated machine set that processes plants through multiple functional stages (gathering, beating, sieving, ventilation) simultaneously, allowing one operator to perform all operations without increasing operational complexity
Solution Approach 2:
The machine set is designed as a universal system where a single operator can control multiple functional components (gathering roller, beating cylinders, vibrating sieve, ventilators, elevators) that work together to complete both harvesting and cleaning tasks
3Reliability
If the vibrating sieve system is used for grain separation, then cleaning is effective, but the sieve is prone to premature wastage
Solution Approach 1:
The vibrating sieve is positioned and operated in a way that protects it from direct impact with heavy obstacles before damage can occur, while still maintaining effective grain separation through vibration
Solution Approach 2:
The beating cylinders act as an intermediary stage before the vibrating sieve, pre-processing the material to reduce large obstacles that could damage the sieve, while the sieve continues to perform effective grain separation
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 machine significantly improves operational efficiency, reduces maintenance needs, and increases productivity by allowing a single operator to perform both harvesting and cleaning operations with reduced wear and tear, while ensuring effective separation of grains from unwanted materials.
Implementation Method 1
wherein the grains and small light particles are vibrated and shaken towards the posterior portion of the machine
Implementation Method 2
wherein ventilators separate the light particles by means of suspension (suction), discarding them through other mouth that is turned to the back of the machine
Implementation Method 3
the inclined motion of which is done hydraulically, the grain bucket of which furthermore is provided with openings so that the level of the grains may be seen and, in addition, is provided with a lateral inclined mouth to facilitate the unloading by free drop

AI summary
A reaper of grains is for reaping bean grains that is classified as a trailer. More specifically, a bean reaper for carrying out two different operations, the first one of which is gathering various plants, such as bean plants, peanuts and other grains, which have been previously plucked and aligned, whereas the second function of which is to perform a whole cleaning process by separating the grains (seeds) from the remaining unwanted parts.
