Solution Overview

Problem

Existing cane harvester accessories face limitations in the proportion of cane picked up due to the compromise in auger inclination angles, which affects the efficiency of cane pickup and separation.

Innovation Solution

A cane pickup and separation device with a vegetation separation device set at a steep inclination of 50° to 75° to the horizontal, featuring a pickup device inclined between 20° to 50°, utilizing a spiral-shaped pickup device with a conical shaft and a leading member to create a three-point contact with the cane, guiding it into a separation zone where sorting augers with opposed rotation directions facilitate efficient separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the augers are set at a larger inclination angle to the horizontal to facilitate separation, then the separation efficiency is improved, but the proportion of cane picked up is significantly limited

Engineering Contradiction:
Improveseparation efficiencyVSAvoidproportion of cane picked up
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The device is divided into two distinct functional segments: a pickup device with a first auger set at a first inclination angle (20°-50°) optimized for pickup, and a separation device with a second auger set at a second inclination angle (50°-75°) optimized for separation. This segmentation allows each component to be optimized for its specific function without compromise, resolving the contradiction between pickup proportion and separation efficiency.

Principle #1Segmentation

2Productivity

If the augers are set at a smaller inclination angle to the horizontal to facilitate pickup from the ground, then the pickup efficiency is improved, but the separation capability is compromised

Engineering Contradiction:
Improvepickup efficiencyVSAvoidseparation capability
Core Design Contradiction:
ProductivityVSManufacturing precision

Solution Approach 1:

The device separates pickup and separation functions into distinct components with different inclination angles. The pickup device operates at a smaller angle (20°-50°) to maximize pickup efficiency, while the separation device operates at a larger angle (50°-75°) to ensure effective separation, eliminating the need for compromise.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The pickup device acts as an intermediary that transfers harvested cane from the ground to the separation device. It picks up cane at a lower inclination angle and delivers it to the separation device, which then performs the separation function at a higher inclination angle, mediating between the conflicting requirements of pickup and separation.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A cane pickup and separation device mountable to a vehicle, the front of which is depicted in FIG. 1 and identified by reference No. 2. The device includes at least two sorting augers with auger tips, a frame, a separation wall, and a pickup spiral. The sorting augers each have auger tips that are adapted to be positioned slightly above ground level. The sorting augers diverge relative to one another and are inclined upwardly and rearwardly at similar inclined angles θ to the horizontal to define a diverging gap. Behind the augers is the upwardly and rearwardly inclined separation wall. The separation wall is rearward of the pair of augers and extends substantially across the diverging gap. The frame is mountable to the vehicle and is adapted to support the pair of sorting augers and the separation wall. The device further includes at least one pickup spiral set at a shallower angle π inclination to the horizontal than the steeply inclined angle θ.
