Description

Technical Field

[0001] This utility model relates to the field of seed selection device technology, and more specifically, to an industrial hemp seed selection device. Background Technology

[0002] In the cultivation and production of industrial hemp, the quality of the seeds directly affects the subsequent growth and yield of the plants. Therefore, the careful selection of industrial hemp seeds is of paramount importance.

[0003] During the harvesting and processing of industrial hemp seeds, impurities such as stems, leaves, insect carcasses, and insect eggs are often mixed in. These impurities not only affect the purity of the seeds but may also have a negative impact on subsequent planting and processing. In order to ensure the purity of industrial hemp seeds, they must be strictly screened to remove impurities.

[0004] Traditionally, the selection of industrial hemp seeds is done manually. However, manual selection is labor-intensive, time-consuming, and unsuitable for large-scale operations, causing inconvenience to workers. Therefore, we propose an industrial hemp seed selection device. Utility Model Content
