Rotary Tiller Tool Unit Vertical Rotation for Furrow Width Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rotary tillers are limited in their ability to adjust the width of the soil section worked and cannot perform ridging operations, requiring separate machines for these tasks.
Innovation Solution
A multifunction rotary tiller with a vertically rotating tool unit and adjustable axis allows for varying furrow widths and direction, enabling both furrowing and ridging capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the rotary tiller uses a fixed tool unit configuration, then the structure is simple, but the width of the soil section worked cannot be adjusted
Solution Approach 1:
The tool unit is made dynamically adjustable through a vertical rod that can rotate around a vertical axis, allowing the operator to change the working width by rotating the tool unit to different angular positions. This dynamic adjustment mechanism enables the same structure to adapt to different soil section widths without requiring multiple fixed configurations.
2Adaptability or versatility
If the rotary tiller uses a fixed tool unit orientation, then the structure is simple, but ridging operations cannot be performed
Solution Approach 1:
The tool unit is designed with multi-functionality by enabling it to perform both furrowing and ridging operations through rotation around the vertical axis. The same tool unit, when oriented at different angles, can create furrows or move earth for ridging, eliminating the need for separate specialized machines and achieving operational versatility without proportionally increasing structural complexity.
3Adaptability or versatility
If the tool unit cannot be rotated around a vertical axis, then the structure is simple, but the direction of earth movement cannot be changed
Solution Approach 1:
The vertical rod enabling rotation around a vertical axis provides dynamic directional control. By rotating the tool unit to different angular positions around this vertical axis, the operator can change the direction in which earth is moved, allowing flexible adaptation to different operational requirements such as furrowing versus ridging without complicating the overall structure.

AI summary
A multifunction rotary tiller (100; 200; 300) for moving the earth and/or generating furrows comprises: a main frame (1), moving means (2) connected to the main frame (1) for supporting and moving the machine, a tool unit (3) to move the earth and/or generate furrows, a connection frame (4) connected to the main frame (1) in such manner to project frontally from the main frame, a vertical rod (8) which supports said tool unit (3) and can rotate around an axis of rotation (Y), and actuation means (9) of the vertical rod connected to said vertical rod (8) to let the vertical rod (8) rotate around its axis of rotation (Y), in such manner to move the tool unit (3) in different positions.
