Solution Overview
Problem
Existing large animal shearing machines face complexity and expense in converting rotary motion to oscillating motion, are prone to malfunctions due to inclined orientations and screw connections, and require difficult shearing head replacements.
Innovation Solution
The shearing machine features an adjustable shearing head holder, aligned axes for motor, eccentric, and rocker arm, a spur gear drive, and a detachable design with vibration-damping components, allowing for simple assembly, reliable operation, and ergonomic handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an eccentric mechanism is used to convert rotary motion to oscillating motion, then the shearing function is achieved, but the device complexity and manufacturing cost increase
Solution Approach 1:
Instead of using a conventional eccentric mechanism where the eccentric center is offset from the rotation axis, this patent inverts the approach by aligning the eccentric shaft's rotation axis with the motor output shaft's axis. The oscillating motion is achieved through the rocker arm's geometric configuration rather than through eccentric offset, thereby simplifying the transmission mechanism while maintaining operational reliability.
Solution Approach 2:
The patent introduces a rocker arm as an intermediary component between the motor output shaft and the shearing head. The rocker arm converts the rotary motion of the aligned shafts into oscillating motion through its pivot point geometry, eliminating the need for complex eccentric mechanisms while ensuring reliable shearing operation.
2Ease of operation
If the shearing head is inclined at more than 30° relative to the shearing machine body, then the cutting action is improved, but the machine becomes prone to malfunction
Solution Approach 1:
The patent makes the shearing head holder adjustable between a mounting position and an operating position. In the operating position, the shearing head achieves the optimal inclination angle for cutting performance, while in the mounting position, the holder is aligned parallel to the shearing machine body for easy shearing head replacement. This dynamic positioning resolves the contradiction between cutting performance and malfunction resistance.
3Ease of operation
If screw connections are used for changing the shearing head, then the shearing head can be detached, but incorrect positioning and malfunctions occur
Solution Approach 1:
The patent introduces a shearing head holder as an intermediary component between the shearing machine body and the shearing head. The holder features a pivot axis that guides the shearing head into the correct position, eliminating positioning errors associated with screw connections. The holder is adjustable to a mounting position where the shearing head can be easily attached or removed, ensuring both replaceability and positioning accuracy.
4Ease of manufacture
If the shearing head holder is fixed in position, then the structure is simple, but shearing head replacement is difficult
Solution Approach 1:
The shearing head holder is designed to be adjustable between two positions: a mounting position where the holder is aligned parallel to the shearing machine body for easy shearing head replacement, and an operating position where the holder is inclined at the optimal angle for cutting performance. This dynamic adjustability maintains structural simplicity while enabling easy shearing head replacement.
