Dual Rotor Drum Chopper Prevents Fibrous Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing plant vine choppers with rotating cutting drums often clog due to fibrous strands wrapping around the drum, reducing chopping effectiveness and requiring frequent interruptions for maintenance.
Innovation Solution
The use of two cooperating rotor drum assemblies with angled blades and rotor rings that slice fibrous strands before they can wrap around the drum, preventing clogging and ensuring consistent chopping through overlapping circular sweeps along the drum's length.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single rotating cutting drum is used, then the device structure is simple, but fibrous strands wrap around the drum causing clogging and reducing chopping effectiveness
Solution Approach 1:
The single drum is divided into two separate drums, each equipped with its own set of cutting blades. This segmentation allows each drum to handle different aspects of the chopping task, with the first drum performing initial cutting and the second drum completing the chopping while being protected from wrapping by guide bars.
Solution Approach 2:
Guide bars are introduced as intermediary elements between the material stream and the second cutting drum. These guide bars intercept fibrous strands before they can reach the second drum, preventing wrapping and clogging while allowing the drum to continue rotating efficiently.
2Productivity
If rotating cutting drums are used, then chopping operation is continuous, but fibrous strands wrap around the drum requiring frequent interruptions for maintenance
Solution Approach 1:
The guide bars perform preliminary anti-action by intercepting and redirecting fibrous strands before they can wrap around the second cutting drum. This preventive measure eliminates the need for frequent maintenance interruptions to remove wrapped material, allowing continuous operation.
3Manufacturing precision
If cutting blades are positioned along the drum, then chopping coverage is improved, but fibrous strands still wrap around the drum reducing efficiency
Solution Approach 1:
Guide bars serve as intermediary protective elements that prevent fibrous strands from reaching the cutting blades on the second drum. This allows the blades to maintain precise positioning for consistent chopping while being protected from wrapping that would reduce efficiency.

AI summary
An organic material and plant vine chopper assembly has two plant vine chopper rotor drum assemblies that chop plant vines and other organic material. Each rotor drum assembly has a plurality of rotor rings each ring having a plurality of angled blades that effectively cooperate with each other to guard each blade and the drum against the wrapping of clogging fibrous strands and other clogging material around the drum. Each chopper rotor drum assembly incorporates a plurality of rotor rings spaced along and encircling and attached to a main drum tube and distributed in a cutting zone along and surrounding the longitudinal rotational axis of the drum tube with each rotor ring having a pair or a plurality of pairs of cutting blades attached to respective alternately angled mounting tabs that alternate to the left and to the right to the general plane of the rotor ring.
