A rapid comparison and sampling device for peanut seed coat color

Abstract

This utility model discloses a rapid peanut seed coat color comparison and sampling device. The core structure includes a cutting blade, a base, a locking mechanism, a contrast color card, and a slot. The cutting blade is connected to the base via a T-shaped moving groove and a sliding locking mechanism, allowing it to slide precisely along the T-shaped sliding groove of the base and locking mechanism. Its cutting surface is used to slice the peanut within the slot. Locking rings on both sides of the base cooperate with the locking mechanism inserts to securely fix the peanut. A contrast color card is embedded above the base, and the edge of the slot has a chamfered bevel to facilitate peanut placement and prevent damage to the seed coat. In use, the peanut is placed in the slot with tweezers. After the cutting blade slices the peanut, the seed coat color can be directly compared using the contrast color card under a standard light source. Magnifying glasses, image recognition software, and other auxiliary tools can be used to improve comparison accuracy and efficiency. This device effectively solves the problems of unstable cutting, easy sample contamination, and inconvenient comparison in existing devices, exhibiting high structural integration and simple operation.
