Hedge Separator for Automated Root Mass and Foliage Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional manual method of transplanting and replanting pre-grown hedges is time-consuming and expensive, and it is difficult to maintain the alignment and continuity of hedgerows when individual sections are handled and replanted, as they often grow together in a nursery setting.
Innovation Solution
A double spade hedge separator attached to a hydraulic tractor, equipped with vertically oriented vegetation cutter assemblies, allows for the automated separation of preselected hedge lengths from a row, enabling efficient cutting and transportation of hedgerow sections in biodegradable trays, which can then be replanted in alignment at the landscaping site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual hand digging and individual wrapping of root balls is used, then each plant can be handled separately, but the process is extremely time-consuming and labor-intensive
Solution Approach 1:
The hedgerow is divided into manageable sections using a mechanical separator that cuts through the root ball and foliage simultaneously. The separator creates discrete segments that can be handled as units, combining the benefits of individual plant handling with automated separation. This resolves the contradiction by segmenting the continuous hedgerow into transportable sections without requiring manual handling of each individual plant.
Solution Approach 2:
Manual hand digging and wrapping operations are replaced with a mechanical separator system equipped with cutting blades and separation mechanisms. The mechanical system performs the separation function that previously required extensive manual labor, dramatically increasing productivity while maintaining the ability to handle discrete plant sections.
2Reliability
If individual plants are dug and wrapped separately, then root balls can be protected, but alignment and continuity are difficult to maintain during replanting
Solution Approach 1:
The mechanical separator performs preliminary actions by pre-cutting the hedgerow into uniformly sized sections with protected root balls before transportation. This preliminary segmentation ensures that when the sections are replanted, their original spacing and alignment characteristics are preserved, making it easier to restore continuity and alignment at the planting site without requiring complex matching procedures.
3Productivity
If larger portions of hedge are handled, then fewer individual plants need to be moved, but handling becomes difficult and time-consuming
Solution Approach 1:
The mechanical separator creates dynamic sections of hedgerow that are optimized for handling. Rather than fixing the section size arbitrarily, the system allows for adjustable segmentation that produces portions large enough to reduce the number of units to transport, yet small enough to remain manageable. This dynamic segmentation resolves the contradiction by finding the optimal balance between section size and handling ease.

Function Achieved in This Case
This method significantly reduces the time and cost associated with transplanting hedgerows by enabling the automated separation and transportation of preselected hedge lengths, allowing for immediate formation of a mature-looking hedgerow without the need for individual plant placement and growth over years.

AI summary
A hedgerow cutter for cutting a hedgerow having a root mass, stalks, branches and foliage, into smaller hedgerow segments is formed of a frame, having a vertically oriented centerline, adapted for attachment to a powered vehicle sized and configured to travel alongside, and parallel to a hedgerow, a root cutting spade assembly sized to be driven down and through the root mass of the hedgerow to cut and thereby separate a segment of the hedgerow root mass from the hedgerow and an elongated hedge cutter assembly, for cutting through the hedgerow stalks, branches and foliage, said hedge cutter assembly attached to the upper portion of the spade assembly and oriented to extend generally upwardly and means for extending the root cutting spade assembly outwardly and downwardly away from the centerline and into the hedgerow root mass to separate the root mass of the hedgerow segment from the hedgerow and extending the hedge cutter assembly into the stalks, branches and foliage of the hedgerow to separate the hedgerow segment from the hedgerow.
