Height-Adjustable Cutting Frame for Parasitic Ear Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for removing parasitic plants from agricultural crops, such as chemical herbicides and genetically modified organisms, are not environmentally friendly and are not compatible with organic farming, while mechanical solutions like hoes and mowers are inefficient for large fields and stony soils.
Innovation Solution
Agricultural machine with a height-adjustable frame, double-blade saw cutting tools, and conveyor belts for precise cutting and collection of parasitic ears, allowing for mechanical removal without chemicals, compatible with organic farming and suitable for various soils and crops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical herbicides are used to remove parasitic plants, then the effectiveness of weed control is improved, but environmental pollution and health risks increase
Solution Approach 1:
The patent replaces chemical herbicide application with a mechanical cutting system consisting of a cutting unit with blades that physically cut parasitic plant stems at ground level, eliminating the need for chemical substances while maintaining effective weed control through mechanical means
Solution Approach 2:
The invention extracts and removes parasitic plant material from the crop field by cutting it at ground level and collecting it in a container, physically separating the harmful weeds from the cultivated crops without using chemicals that would pollute the environment
2Reliability
If row croppers are used to cut parasitic ears, then the removal of weeds is achieved, but the applicability to different field types is reduced
Solution Approach 1:
The cutting unit is designed with adjustable height and a wide working width that can accommodate different crop types and field conditions, including stony soils and various soil types, making the machine universally applicable across diverse agricultural environments rather than limited to specific row configurations
Solution Approach 2:
The cutting unit features adjustable height relative to the chassis, allowing the cutting blades to be positioned at different levels to adapt to various crop heights and field conditions, enhancing the machine's versatility across different agricultural scenarios
3Productivity
If mowers are used to cut parasitic ears, then the cutting of abundant vegetation is improved, but the precision of targeted removal is reduced
Solution Approach 1:
The cutting unit is designed to cut only the taller parasitic weed stems that protrude above the crop canopy while leaving the shorter cultivated crops untouched, achieving selective targeted removal through local differentiation of cutting height and blade positioning rather than uniform cutting across all vegetation

AI summary
The invention relates to an agricultural machine for removing parasitic ears that protrude vertically from a cultivated plant species on a cultivation area (12) comprising: a chassis and chassis movement elements in a direction of advancement and along a principal direction of advancement, called the longitudinal direction, said movement elements having contact areas with the cultivation area (12); cutting tools (14) extending in a direction perpendicular to the longitudinal direction, called the transverse direction, and mounted on a frame adjustable in height relative to said chassis so as to be able to position the cutting tools at the level of the parasitic ears to be cut; a hopper (17) for collecting the ears cut by said cutting tools (14), said collection hopper (17) being connected to said chassis;means of conveying (16, 18) the cut ears carried by said height-adjustable frame and extending between the cutting tools (14) and said bin (17) for collecting the cut ears.;
