Description

Technical Field

[0001] The utility model relates to the technical field of seed processing, in particular to a seed opening device. Background Art

[0002] Seed dormancy is common in higher plants, and hard and dense seed shells are the main exogenous cause of seed dormancy. For example, the seeds of Cyclobalanopsis gracilis, Cyclobalanopsis myrsinifolia, and Cyclobalanopsis multinervis have poor permeability to air and water, and need to be stored in low-temperature sand for more than 4 months before germination, which greatly shortens the growth time of seedlings and increases seed storage costs. Seed shell incision treatment is an effective way to quickly break seed dormancy.

[0003] Most of the existing methods for opening the seeds of Cyclobalanopsis are to manually use knives to open the seeds. Manual seed processing is slow and inefficient. The extended processing time will cause the seeds to lose water. At the same time, the depth and length of the manually processed seed pieces are uneven, affecting the uniformity of the seedlings. Summary of the invention

[0004] In order to reduce labor costs, improve seed processing efficiency, and achieve rapid seed germination, the utility model proposes a seed opening device, in which a tool is arranged on the lower side of a first pressure plate.
