AI Technical Summary

Technical Problem

The moving blades of existing forage chopping devices are mostly independent and fixed structures, which are inconvenient to adjust. This leads to inconsistent gaps between the moving and fixed blades, resulting in uneven forage particle size and affecting livestock feeding and digestion.

Method used

An adjustment component is used to control multiple moving blade groups to move together or apart synchronously. The gap between the moving blade and the fixed blade is adjusted evenly through a lead screw and sliding ring structure. A magnetic block is used to fix the position to avoid errors caused by vibration.

Benefits of technology

By ensuring that the gap between all moving and stationary blades is uniform, the quality of feed processing is improved, and uneven chopping caused by adjustment errors of a single blade is avoided.
