Description

Seed crust circulation grinding device Technical Field The invention relates to the technical field of seed polishing, in particular to a seed crust circulating polishing device. Background In the long-term evolution process of seeds of a plurality of plants (such as Davidia involucrata, su iron and the like), an abnormally thick or compact exodermis structure is formed for resisting gastric acid corrosion of animals, severe environmental temperature and humidity changes or adapting to adverse conditions such as drought, high temperature and the like. However, due to climate change or habitat migration, when these seeds are in a new artificial cultivation or natural growth environment, the original thick seed coat structure becomes a key obstacle for limiting germination, namely, the seed coat is blocked from water permeation and ventilation, embryo germination and shell breaking are inhibited, so that the natural breeding rate of the seeds is extremely low, and the seeds are in a disadvantage in the survival competition, which is one of the important reasons that part of plants gradually fall into rare species. On the other hand, in the artificial breeding process of commercial crops such as rhus chinensis and plums, the problems of low germination rate, poor germination uniformity and the like of seeds caused by too thick seed coats are also common. To improve such conditions, the prior art generally employs chemical and physical treatments such as prolonging the seed soaking time, increasing the water temperature for soaking seeds, or soaking with acid-base solution. However, these conventional approaches have little effect on seeds with particularly thick seed coat structures, are difficult to achieve stable, uniform seed coat treatments, and are prone to potential damage to the embryo due to improper handling. The outer seed coats of the seeds are removed thinly by adopting a mechanical polishing mode, so that the germination rate of the seeds can be effectively improved, and the germination uniformity is remarkably improved. However, in view of small individual seeds, irregular shapes, difficult holding and fixing, the manual polishing mode has low efficiency and is difficult to realize uniform treatment, and the practical operability is not realized at all.
