Conveying Device for Mowed Straw with Adjustable Inflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional conveying devices for mowed crops struggle with uniform swath formation, particularly when handling small quantities of stalks, resulting in inhomogeneous deposition.
Innovation Solution
A conveying device with a drive-connected pin and a pick-up device featuring adjustable conveying tines and an inflow surface, allowing for variable angle adjustments and rotation relative to the travel direction, ensuring uniform swath formation by pivoting the receiving device and maintaining constant orientation of sliding means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the inflow surface has a fixed incline for swath formation, then larger amounts of stalks can be transported, but swath formation becomes irregular with small amounts of stalks
Solution Approach 1:
The patent applies the dynamics principle by making the inflow surface adjustable in angle relative to the receiving device. The incline angle can be dynamically changed depending on the amount of crop being transported. For large amounts of stalks, a steeper incline is used to facilitate transport, while for small amounts, a gentler incline ensures uniform deposition and regular swath formation. This dynamic adjustment resolves the contradiction between handling variable quantities and maintaining consistent swath quality.
2Adaptability or versatility
If the conveying device is steerable to adapt to different working conditions, then versatility is improved, but the orientation of sliding means may change causing inconsistent performance
Solution Approach 1:
The patent applies segmentation by separating the steering function from the sliding means orientation. The conveying device can be steered to adapt to different working conditions and positions, while the sliding means (inflow surface) maintains its orientation relative to the receiving device through the adjustable connection. This allows the overall device to be versatile while the critical sliding component maintains consistent functional orientation, resolving the contradiction between adaptability and reliability.
