Variable Angle Beet Pick-Up Device Dirt Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pick-up apparatuses for root crops, such as sugar beets, suffer from dirt accumulation under the cleaning members, leading to wear and blockage, which reduces their efficiency and yield.
Innovation Solution
The pick-up apparatus features a variably adjustable hydraulic cylinder for adjusting the position of the pick-up section and cleaning members, including a dirt outlet for evacuating dirt and independent inclinability of the pick-up and supplementary pick-up sections, allowing for optimized cleaning and reduced blockage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pick-up apparatus uses cleaning members to clean root crop, then the root crop is cleaned effectively, but dirt accumulates under the pick-up apparatus causing wear and blockage of cleaning members
Solution Approach 1:
The invention extracts the harmful dirt accumulation from the system by providing a dirt outlet that allows dirt to be removed from underneath the pick-up apparatus. The cleaning members are designed to facilitate dirt removal, separating the cleaning function from the dirt retention problem, thereby preventing wear and blockage while maintaining effective cleaning.
Solution Approach 2:
The invention changes the geometric parameters of the pick-up apparatus by inclining the pick-up section relative to the intermediate section. This angular parameter change allows dirt to slide off the cleaning members more easily, preventing accumulation while maintaining cleaning effectiveness. The slope angle is optimized to balance cleaning performance with dirt removal.
2Productivity
If the pick-up section and cleaning members are fixed in position, then the structure is simple, but the apparatus cannot adapt to different crop conditions and yields are reduced
Solution Approach 1:
The invention transforms the static pick-up section into a dynamic, adjustable component. The pick-up section can be inclined relative to the intermediate section, and cleaning members can be adjusted independently, allowing the apparatus to adapt to different crop conditions and optimize yield while managing dirt accumulation through variable geometry.
Solution Approach 2:
The adjustment mechanisms provide multi-functionality: the same inclined pick-up section geometry serves both to optimize crop pickup for different conditions and to facilitate dirt removal. The cleaning member adjustment serves both cleaning optimization and dirt outlet alignment, reducing the need for separate mechanisms.
3Reliability
If dirt is allowed to accumulate under the pick-up apparatus, then the structure is simpler without dirt outlets, but cleaning members suffer wear and blockage
Solution Approach 1:
The invention extracts the harmful dirt from the system through dedicated dirt outlets positioned beneath the pick-up section. This extraction function is integrated into the existing structure, allowing dirt removal without adding major complex subsystems, thereby protecting cleaning members from wear and blockage.
Solution Approach 2:
The inclination angle of the pick-up section serves dual purposes: optimizing crop handling and facilitating dirt gravity-driven removal. By changing this geometric parameter, the system enables dirt egress without requiring active removal mechanisms, balancing simplicity with reliability.

AI summary
This pick-up apparatus (10) for picking up harvested root crop defines a pick-up plane PP and comprises a pick-up section (20). The pick-up section comprises a pick-up member (22) adapted to pick up the root crop, and a cleaning member (24). The pick-up member (22) defines a pick-up position with respect to the pick-up plane PP. The pick-up apparatus comprises a cleaning adjustment device (32) adapted to adjust the position of the cleaning member (24) between at least two cleaning positions, the cleaning positions being different one from another. In each of the cleaning positions of the cleaning member (24) and while the pick-up member (22) is in the pick-up position, the distance DC1 of the cleaning member (24) with respect to the pick-up plane PP is different from the distance DC2 of the cleaning member (24) with respect to the pick-up plane PP in the other cleaning position.
