Rotatable Crossbeam Soil Cultivation Machine
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional soil tillage machines are limited in their ability to cultivate the entire soil surface with a minimum number of shares and low working depth, leading to reduced effectiveness, especially for shallow mechanical weed control, due to the deformation of spring tines under operating forces which increases the angle of cutting edges and reduces the effective working width.
Innovation Solution
A soil tillage machine design featuring rotatable crossbeams with spring tines, where the rotational position of the crossbeams can be adjusted based on operating forces to maintain cutting edges parallel to the forward direction, allowing for full-surface cultivation without increasing the number of shares or working depth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If spring tines are used to mount goosefoot shares, then the shares can penetrate the soil, but the tines deform under operating forces increasing the cutting edge angle and reducing effective working width
Solution Approach 1:
The crossbeam is made rotatable about a longitudinal axis, allowing the assembly to dynamically adjust its orientation in response to operating forces. This dynamic adjustment compensates for tine deformation, maintaining the cutting edges parallel to the forward direction and preserving full working width throughout the tillage process.
Solution Approach 2:
The system changes the orientation parameter of the crossbeam relative to the longitudinal beam. By allowing rotation, the orientation angle can vary to compensate for tine deflection under load, ensuring that the cutting edges maintain their optimal parallel orientation despite changes in operating conditions.
2Area of stationary object
If the number of goosefoot shares is increased to cultivate the full soil surface, then full-width cultivation is achieved, but the cost and device complexity increase
Solution Approach 1:
The rotatable crossbeam assembly allows each share to maintain its full working width capability throughout operation. This ensures that fewer shares are needed to cover the same total area, as each share operates at maximum efficiency without width loss from deformation.
Solution Approach 2:
The rotatable crossbeam design makes each share assembly universally adaptable to varying operating conditions. The same assembly can maintain optimal performance across different soil types and working depths, replacing the need for multiple specialized shares.
3Area of stationary object
If working depth is increased to utilize full share width, then more soil is cultivated, but the machine cannot perform shallow weed control
Solution Approach 1:
The rotatable crossbeam assembly maintains cutting edge parallelism across the full range of working depths. Whether operating at shallow depths for weed control or deeper depths for tillage, the dynamic rotation ensures optimal orientation is maintained, enabling the machine to effectively perform both shallow and deep operations.
4Force
If cutting edges are oriented at an angle for penetration, then shares penetrate soil better, but they cannot cultivate the full surface width
Solution Approach 1:
The crossbeam is designed to rotate dynamically, allowing the cutting edges to maintain a parallel orientation to the forward direction during operation. This dynamic adjustment ensures that the full width of each cutting edge remains in contact with the soil surface, maximizing effective working width while maintaining penetration capability through the spring tines.
