V-Shaped Ditch Blade Assembly with Integrated Roller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tractor implements like box blades and grader blades are limited in efficiently moving and compacting loose dirt, requiring multiple passes and additional equipment, which is time-consuming and costly.
Innovation Solution
A dual blade assembly with blades oriented at an angle to direct dirt into a central channel, optionally including a roller for compaction and weight adjustment, allowing for a single pass to fill trenches effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single blade is used perpendicular to the tractor, then the blade can scrape and push dirt, but it cannot efficiently direct dirt into a trench or provide compaction
Solution Approach 1:
The single blade is divided into two separate blades that can be independently oriented. Each blade is mounted on its own adjustable arm, allowing them to be positioned at different angles to efficiently direct dirt from both sides of a trench into the center, while the tractor maintains a straight path.
Solution Approach 2:
The blade arms are made adjustable and reconfigurable, allowing the operator to change the orientation and position of each blade according to different trench-filling scenarios. This dynamic adjustment capability enables the same implement to adapt to various field conditions and trench configurations.
2Productivity
If the tractor shifts to one side to allow the blade to slide dirt into the trench, then dirt can be moved, but the tractor tires may get too close to or fall into the trench
Solution Approach 1:
The single blade function is segmented into two blades that can work simultaneously from opposite sides of the trench. This allows the tractor to remain centered and stable on level ground while both blades independently direct dirt into the trench, eliminating the need for the tractor to shift position.
3Reliability
If multiple passes are used to fill and compact the trench, then thorough compaction is achieved, but time and fuel consumption increase
Solution Approach 1:
The trench-filling operation and the compaction operation are merged into a single integrated implement. The two blades fill the trench while a rear roller simultaneously compacts the deposited dirt, allowing both functions to be performed in one pass rather than requiring separate operations.
Solution Approach 2:
The implement is designed to perform multiple functions simultaneously: it acts as both a trench-filling device (via the two adjustable blades) and a compaction device (via the integrated roller). This multi-functionality eliminates the need for separate compaction passes, saving time and fuel.
4Reliability
If additional equipment is used for compaction after filling, then compaction is achieved, but equipment cost and operational complexity increase
Solution Approach 1:
The compaction roller is integrated into the same implement frame as the two blades, creating a single unified device that performs both filling and compaction. This eliminates the need for separate compaction equipment and simplifies the overall system configuration.
Solution Approach 2:
The implement is designed as a multi-functional device that combines trench-filling blades with an integrated compaction roller, allowing one piece of equipment to replace what would traditionally require multiple separate implements.

AI summary
A ditch blade assembly includes a frame coupling opposing blades oriented in a V-shape. The blades are configured to scrape the ground or surface matter to distribute that matter into a singular channel and/or smooth the surface of the ground. A roller is included to compact the loose dirt exiting the gap between the blades. One or more weights are included to increase the down pressure on the blades. The blade angle may be adjusted with both a manual and hydraulic operating assembly.
