Seeder With Adjustable Presser Roller For Simultaneous Seeding And Rolling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current seeders require separate operations for seeding and soil rolling, which are time-consuming and economically inefficient, often necessitating the use of tractors and small rollers that are not always suitable.
Innovation Solution
A seeder design that integrates a seed distribution apparatus with a presser roller, adjustable via a hydraulic actuator, allowing simultaneous seeding and rolling with independent control of roller pressure and position, attached to an agricultural tractor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate operations are used for seeding and rolling, then each operation can be performed with dedicated equipment, but the total time and economic efficiency deteriorate due to multiple tractor operations
Solution Approach 1:
The patent combines the seed distribution apparatus and presser roller into a single integrated seeder unit that performs both seeding and rolling operations simultaneously. The presser roller is positioned directly behind the seed distribution apparatus, allowing seeds to be deposited and immediately pressed into the soil by the same machine, eliminating the need for separate seeding and rolling operations with multiple tractors.
2Productivity
If a small roller is associated with the seeder, then rolling can be performed during seeding, but the suitability and effectiveness deteriorate because small rollers are not always appropriate for the task
Solution Approach 1:
The presser roller is designed with adjustable pressure control through a hydraulic actuator that can independently move the supporting frame relative to the supporting structure. This allows the roller pressure to be dynamically adjusted to match different soil conditions and crop requirements, ensuring optimal rolling quality rather than using a fixed small roller.
3Device complexity
If the presser roller pressure is fixed, then the structure remains simple, but the adaptability to different soil conditions and crops deteriorates
Solution Approach 1:
A hydraulic actuator is introduced to provide independent movement of the supporting frame carrying the presser roller. This hydraulic system enables adjustable pressure control of the roller against the ground, allowing adaptation to various soil types and crop requirements while maintaining a relatively simple overall structure through the use of standard hydraulic components.
