Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a high-efficiency flotation device for agricultural rice seeds. Background technique [0002] Paddy refers to the fruit without removing the rice husk, which belongs to the common rice subspecies in the common cultivated Oryza subgenus of the genus Poaceae Oryza botany. A total of 22 types of rice have been identified by humans, but the only one used for bulk trade is the Oryza Sativa L. type of rice, the common type of rice. It is a 50-130 cm tall annual plant with a main stem that forks at the base into several tillers that end in conical flower clusters. Each flower cluster can grow 50-500 small spikes, and each small spike can give a fruit, that is, a nucleolus. The fruit is not completely separated from the plant structure of the flower cluster after harvest. It is one of the most important food crops in my country. The sown area of ​​rice in China accounts for about...

Problems solved by technology

[0003] Rice is an important source of food for people. In order to meet people's food needs, a large amount of rice needs to be planted. Rice planting first needs to be selected, and the quality of the seeds affects the harvest of rice. Water selection is often used for seed selection, and The current seed water separation device has the disadvantages of poor water separation effect and difficult separation of unqualified seeds (impurities). Therefore, it is urgent to develop an agricultural rice that can continuously and quickly water-select agricultural rice seeds, save energy and protect the environment, and is conducive to popularization.
