Reversible Parallel Plow With Independent Transverse Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Full reversible plows face challenges in achieving a large working width without increasing resistance during rotation and incurring large one-sided lever forces on the axis of rotation, which limits their efficiency and compactness.
Innovation Solution
A plow design featuring at least two transverse frames with turning axes aligned parallel to the working direction, allowing for independent rotation of cross frames to change between left-turning and right-turning positions, with a rotating mechanism and actuator system to manage ground clearance and balance weight distribution, enabling a larger working width while maintaining compactness and reducing torque requirements.

Engineering Contradiction Analysis
1Area of stationary object
If the number of plough bodies is increased to increase the overall working width, then the working width is improved, but the torque required to rotate the carrier and the one-sided lever forces on the bearing increase significantly
Solution Approach 1:
The plough is divided into multiple independent transverse frames (at least two), each carrying its own plough bodies and rotating independently about its own turning axis. This segmentation allows the working width to be increased by adding more frames without proportionally increasing the rotation torque, as each frame rotates separately with smaller individual leverage forces.
2Shape
If the plough beam is aligned at an angle to the working direction to ensure sufficient ground clearance during position change, then the ground clearance is improved, but the length of the plough in the working direction increases considerably
Solution Approach 1:
The turning axes of the transverse frames are aligned parallel to the working direction (changing the orientation dimension), which allows the plough bodies to clear the ground during rotation without requiring the plough beam to be angled. This maintains a compact plough length in the working direction while ensuring adequate ground clearance through the parallel axis arrangement.
3Length of moving object
If the plough is designed as a bed plough with plough bodies mounted only in the width direction, then the plough length in the working direction is reduced, but the plough cannot perform U-turns and requires dividing the field into multiple parts
Solution Approach 1:
The transverse frames are designed to be rotatable about turning axes parallel to the working direction, enabling dynamic reconfiguration between left-turning and right-turning positions. This dynamic capability allows the compact parallel plough design to perform U-turns and switch working directions, achieving reversibility without increasing the plough length in the working direction.
