Description

Technical Field

[0001] The utility model belongs to the technical field of rice breeding, and in particular relates to a screening device for rice breeding. Background Art

[0002] Rice breeding refers to the cultivation of rice varieties that are adapted to different environments and needs through artificially controlled hybridization, selection and improvement. Modern rice breeding aims to improve yield, disease and pest resistance, stress tolerance and quality. During breeding selection, screening devices are required to screen rice seeds.

[0003] A Chinese patent with application number CN202321556914.7 discloses a rice breeding screening device, including a screening box, wherein the interior of the screening box is provided with a first screen plate, a second screen plate and a material plate from top to bottom, and the first screen plate, the second screen plate and the material plate are all arranged in a downward inclined shape.

[0004] The above scheme collects rice seeds through the first sieve plate and the second sieve plate, and the screened rice seeds are collected by the material plate. However, in actual use, when the first sieve plate and the second sieve plate are used to screen the rice seeds, due to the accumulation of rice seeds or the clogging of the sieve holes by some larger rice seeds, some smaller rice seed particles cannot effectively pass through the sieve plate and are collected together with the larger rice seeds, resulting in poor rice seed screening effect and affecting the quality of rice seed selection.

[0005] In view of this, the present utility model is proposed. Utility Model Content
