Tine Control for Balers: Simplified Drive Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing agricultural piston bale presses have complex drive mechanisms for the selective movement of tine arms along loading and stuffing trajectories, requiring intricate designs.
Innovation Solution
A simplified tine arm drive mechanism with a crank mechanism and rotational drive, allowing the tine arm to move in a cyclic, constant trajectory, with tines that can pivot between extended and retracted positions to follow different trajectories for efficient stuffing and loading of crop material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex drive mechanism is used to selectively move the tine arm along different trajectories, then the stuffing and loading functions can be performed, but the device complexity increases
Solution Approach 1:
The patent applies the dynamics principle by making the tines movable relative to the tine arm through a locking mechanism. The tines can be locked in a fixed position for loading trajectory or unlocked to pivot freely for stuffing trajectory. This dynamic configuration allows a single simplified drive mechanism to achieve multiple trajectories without requiring complex selective positioning systems.
Solution Approach 2:
The patent implements self-service by using crop material itself to control the tine position. During stuffing operation, crop material in the feed passage automatically pushes the tines into the retracted position without requiring active control mechanisms. The system uses the work environment (crop material presence) to automatically configure the tine position, eliminating the need for complex trajectory selection mechanisms.
2Device complexity
If a simplified drive mechanism is used, then the device complexity is reduced, but the ability to perform selective movement along different trajectories may be compromised
Solution Approach 1:
The patent applies the dynamics principle by making the tines movable relative to the tine arm through a locking mechanism. The tines can be locked in a fixed position for loading trajectory or unlocked to pivot freely for stuffing trajectory. This dynamic configuration allows a single simplified drive mechanism to achieve multiple trajectories without requiring complex selective positioning systems.

3Device complexity
If the tines are fixed on the tine arm, then the structure is simpler, but the ability to follow different trajectories is limited
Solution Approach 1:
The patent applies the dynamics principle by making the tines movable relative to the tine arm through a locking mechanism. The tines can be locked in a fixed position for loading trajectory or unlocked to pivot freely for stuffing trajectory. This dynamic configuration allows a single simplified drive mechanism to achieve multiple trajectories without requiring complex selective positioning systems.
