Description

  TECHNICAL FIELD The present invention relates to a seed sorghum sorting apparatus for removing incomplete pods from seed cultivated and dried for seed sorghum to obtain a healthy seed pod.

  The seeds harvested and dried for use as seed seeds contain healthy seed seeds and imperfect seeds in a considerable proportion, so that in order to obtain healthy seed seeds, it is necessary to select and remove the incomplete seed seeds.

  Conventionally, as a most reliable seed selection means, salt water selection has been widely used in which seed seeds are soaked and stirred in salt water having a specific concentration (specific gravity: about 1.13) to remove floating grains. No. 8-187464, JP-A-8-187465, or JP-A-8-192109, see paragraph “0002”).

  From the point of view of selecting the seeds to obtain a healthy seed pod, the salt water selection of the seed pod is an excellent selection means from the point that incomplete grains can be surely eliminated. However, since high-concentration salt water must be used, in recent years, not only environmental pollution and environmental destruction due to the waste water have been seen as a problem, but also seeds soaked in salt water must be washed and dried. Many problems were pointed out.

  Thus, even if the salt water selection of the seed potato widely performed is excellent in the selection function, there are many disadvantages, but the above-mentioned JP-A-8-187464 and JP-A-8-187465 are also mentioned. Japanese Laid-Open Patent Publication No. 8-192109 introduces specific gravity selection means by swinging seed pods.

As for the means for removing the seeds, the CD-ROM of Japanese Patent Application Laid-Open No. 5-23601, Japanese Utility Model Application No. 3-65524 (Japanese Utility Model Application Laid-Open No. 5-9641), Japanese Patent Application Laid-Open No. 63-208, Japanese Patent Application Laid-Open No. No. 57-122703 or JP-A-8-19305, respectively.
JP-A-8-187464 JP-A-8-187465 JP-A-8-192109 Japanese Patent Laid-Open No. 5-23601 CD-ROM of Japanese Patent Application No. 3-65524 (Japanese Utility Model Publication No. 5-9641) Japanese Unexamined Patent Publication No. 63-208 JP-A-57-122703 JP-A-8-19305

  By the way, the specific gravity selecting means by the shaking of the seed pod introduced in the above-mentioned Japanese Patent Laid-Open Nos. 8-187464, 8-187465, or 8-192109 is a granule having a small specific gravity by the rocking. Due to the sorting action that floats on the upper layer of grains with high specific gravity and separates the lower layer grains as healthy seeds, the separation between the grains that sink in the lower layer and the grains that float on the upper layer is incomplete. Therefore, it was impossible to select a highly reliable seed pod comparable to saltwater selection.

  Therefore, the present invention is based on the new knowledge that the pods, which are full of fruits and have an outer shape, are particularly excellent in germination ability, growth ability, bacterial resistance, and potato resistance. After the treatment, the seeds that have been removed are slidably contacted with the screen of the specified mesh to eliminate the particles that pass through the screen, so that the remaining rice without passing through the screen of the screen is sound.
