Agricultural Raking Machine With Remote Hydraulic Comb Speed Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural raking machines require manual adjustment of comb rotation speed, necessitating vehicle stops and interruptions for adjustments, which is inconvenient and inefficient.
Innovation Solution
An agricultural raking machine with adjustable comb-like elements that allows speed adjustment during operation through a hydraulic actuation system and remote control, enabling continuous operation without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual adjustment of comb rotation speed is implemented, then the rotation speed can be adjusted to match material conditions, but the operation requires vehicle stops and interruptions
Solution Approach 1:
The system allows the operator to adjust comb rotation speed remotely from the tractor cab without leaving the vehicle or stopping operation. The control unit receives adjustment commands and automatically implements speed changes through the hydraulic system, enabling the system to serve itself during operation.
Solution Approach 2:
A remote control system acts as an intermediary between the operator and the comb adjustment mechanism. The control unit in the tractor cab communicates with the comb actuation system through hydraulic control lines, allowing speed adjustment without direct manual intervention at the comb location.
2Measurement precision
If manual valve adjustment is required for speed control, then precise speed setting is possible, but the adjustment process becomes complex and time-consuming
Solution Approach 1:
The manual mechanical valve adjustment system is replaced with a hydraulic control system actuated by a control unit. The operator uses a simple control mechanism in the tractor cab that automatically translates operator input into precise comb speed adjustments through hydraulic actuation, eliminating the need for manual valve manipulation.
Solution Approach 2:
The control unit serves as an intermediary that converts simple operator inputs into precise hydraulic control signals. This intermediary system handles the complexity of precise speed setting automatically, presenting a simple interface to the operator while maintaining precise control capability.
