Screening and drying apparatus for rice seeds

Abstract

The invention relates to the field of seed drying, in particular to screening and drying apparatus for rice seeds. The screening and drying apparatus for the rice seeds comprises a support and a screening box arranged on the support. A conveying device is arranged on the support. A water conveying device for screening and washing the seeds is also arranged on the support. A screening device is arranged on the screening box. An opening-and-closing device is arranged at the bottom of the screening box, wherein the opening-and-closing device is used for allowing the seeds screened to fall. A drying device is arranged at a lower end of the screening box, wherein the drying device is used for drying the seeds washed. A draining device for draining water is arranged inside the screening box. According to the screening and drying apparatus for the rice seeds, the rice seeds are screened and washed in a large scale; compared with traditional manual screening and washing, the screening cardinalnumber is large; washing efficiency is high; production efficiency is improved; the cost is lowered; and one end of a water conveying pipe is arranged to be a shape with certain radian, influence anddamage caused to the rice seeds due to drainage can be reduced, and screening efficiency and washing efficiency are guaranteed.

Description

technical field [0001] The invention relates to the field of seed drying, in particular to a rice seed screening dryer. Background technique [0002] Due to lack of knowledge of seed treatment technology and immature mastery of treatment level by many growers, the growth and development of rice are greatly affected. Seed treatment before rice sowing is a very important step. Rice seeds Treatment is one of the key factors in rice seedling raising, which is conducive to improving the germination quality of rice seeds, preventing the empty seed shells from causing small rice yields, and affecting the harvest of growers. However, when large quantities of rice seeds need to be distinguished from those that can be sown , traditional labor makes this step particularly difficult, seriously affecting production efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a rice seed screening dryer. [0004] A rice seed scree...
