Description

Technical Field

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

[0002] Lotus belongs to the Nymphaeaceae family of the Ranunculales order. It is the general name for two plants of the genus Nelumbo. It is also known as lotus and water hibiscus. It is a perennial aquatic herb with long and thick rhizomes with long nodes and round leaf shields. It blooms from June to September. It grows solitary at the top of the pedicel. It has many petals that are embedded in the receptacle hole. They are red, pink, white, purple, etc., or have colored patterns and borders.

[0003] In the process of lotus planting, it is necessary to select seeds with larger and fuller particles for planting. Seeds with insufficient particle size and fullness not only have a low survival rate, but also, due to genetic characteristics, the fruits and flowers produced after planting are relatively small. Therefore, it is necessary to screen the seeds of the planted lotus. Therefore, a lotus seed screening device is needed.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the existing lotus seed screening device is used, impurities are usually removed directly through the sieve, and then the lotus seeds that do not meet the particle size and fullness requirements are manually selected one by one. Such screening efficiency is extremely low, and it is not suitable for large-scale lotus seed screening and cannot meet people's needs. Utility Model Content
