Single-Pass Cotton Stalk Eliminator with Subsoiler Wing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for removing cotton stalks after harvesting require multiple passes with mowers and disc harrows, causing wear on equipment, fuel consumption, and environmental harm, while failing to efficiently prepare the field for replanting or cover crops.
Innovation Solution
A tractor-towed agricultural apparatus with angled blades on rotating cylinders and a subsoiler wing that chops, uproots, and re-chops cotton stalks and roots in a single pass, featuring self-cleaning design and a crumbler for clod crushing, allowing for efficient field preparation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple passes with mowers and disc harrows are used to remove cotton stalks, then the stalks are eventually removed, but equipment wear increases and fuel consumption rises
Solution Approach 1:
The patent combines multiple stalk removal functions (chopping, uprooting, re-chopping) into a single integrated apparatus that performs all operations in one field pass, eliminating the need for multiple separate passes with different equipment and thereby reducing fuel consumption and equipment wear
Solution Approach 2:
The apparatus is designed as a multi-functional device that simultaneously chops stalks, uproots them using subsoiler wings, and re-chops them with rear cylinders, allowing one piece of equipment to replace multiple specialized tools and perform complete stalk elimination in a single operation

3Productivity
If traditional choppers are used to chop cotton stalks, then the stalks are cut, but they clog up with clay or damp soil
Solution Approach 1:
The blades are designed with self-cleaning geometry that allows them to automatically clear clay and damp soil during operation, preventing clogging without requiring external intervention or maintenance stops
Solution Approach 2:
The blades feature asymmetric geometry with specific angle configurations that create self-cleaning action, where the blade shape and orientation cause soil and debris to be thrown off rather than accumulated during the chopping operation
4Productivity
If a single-pass stalk elimination apparatus is used, then fuel consumption and equipment wear are reduced, but the apparatus must perform multiple functions simultaneously
Solution Approach 1:
The apparatus is divided into distinct functional modules (front chopping cylinders, subsoiler wings for uprooting, rear chopping cylinders, crumbler) that can be independently designed, maintained, and replaced, managing complexity through functional segmentation while achieving multiple operations in one pass

AI summary
The stalk eliminator chops stalks, uproots stalks, and re-chops stalks. The apparatus includes a front stalk chopper on a rotating cylinder with angularly attached blades. A plow tool attaches to the apparatus and provides a subsoiler wing behind and under the front stalk chopper. A rear stalk chopper on a rotating cylinder with angularly attached blades follows the plow tool.
