Tractor Tool Carrier Axle Positioning for Dual-Row Weeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current tool-carrying devices for tractors require frequent driver intervention to position tools correctly, reducing forward speed and increasing operating costs due to the need for more frequent mechanical weeding, which also increases fuel consumption and environmental impact.
Innovation Solution
A tool-carrying device mounted on a tractor with an interior tool carrier and exterior tool holder system, allowing tools to be positioned between the front and rear axles, enabling simultaneous processing of two rows while maintaining driver control, reducing the need for frequent driver intervention and enhancing operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the tractor driver manually positions the tools by looking ahead and behind, then the tools can be positioned correctly relative to the rows, but the forward speed is reduced and operating costs increase
Solution Approach 1:
The tool holder is designed to automatically position itself relative to the rows using the tractor's own movement and the geometric relationship between the tool holder and the rows. The system self-regulates without requiring driver intervention, as the tools are carried at a fixed position that automatically aligns with the rows during tractor movement.
Solution Approach 2:
The tool holder is pre-configured with a specific geometric arrangement where the tools are positioned at predetermined locations relative to the tractor. This preliminary positioning ensures that when the tractor moves forward, the tools automatically align with the rows without requiring real-time adjustment by the driver.
2Object-affected harmful factors
If mechanical weeding is performed more frequently to achieve the same weeding result, then chemical usage is eliminated, but operating costs and fuel consumption increase
Solution Approach 1:
The tool holder enables continuous weeding action along the entire length of the rows without interruption or repeated passes. By positioning multiple tools simultaneously at different locations, the system performs continuous useful work in a single pass, eliminating the need for frequent repeated operations and reducing fuel consumption.
Solution Approach 2:
The invention transitions from sequential weeding (one row at a time, multiple passes) to parallel weeding (multiple rows simultaneously, single pass). This dimensional change in the working approach allows treating multiple rows at once, reducing the total number of passes required and thereby reducing fuel consumption.
3Measurement precision
If the driver frequently checks the avoidance systems, then the positioning accuracy is maintained, but the forward speed is reduced
Solution Approach 1:
The system eliminates the need for driver monitoring by making the tool holder self-regulating. The geometric design and fixed positioning ensure automatic alignment with the rows, freeing the driver from the need to frequently check positioning and allowing maintained forward speed.

AI summary
The invention relates to a tool-carrying device configured for mounting on a tractor, characterized in that it comprises: - an inner tool carrier (32) having at least one lower cross member (36) positioned under the tractor's engine block between the front and rear axles, to which at least one right-hand inner tool and at least one left-hand inner tool (30.2) are connected; - an outer tool carrier (34) having right and left uprights (52, 54) positioned on either side of the tractor's engine block, and at least one upper cross member (56) connecting the right and left uprights (52, 54), positioned above the tractor's engine block, to which at least one right-hand outer tool and at least one left-hand outer tool (30.4) are connected. This tool-carrying device allows two complete rows to be worked in a single pass.Positioning the tools between the front and rear axles of the tractor allows the driver to control them while driving the tractor and frees up the tractor's rear hitch.
