Description

  The present invention relates to a seed sorghum sorting apparatus that obtains healthy seed pods by removing incomplete pods from seed pods harvested and dried as seed pods.

  Since seed pods harvested and dried as seed pods contain healthy seed pods and imperfect pods in a considerable proportion, it is necessary to select and remove incomplete pods in order to obtain good quality seed pods.

  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”).

  Since the selection of salt water for seed potatoes can reliably eliminate incomplete grains, it is an excellent means from the viewpoint of selection for obtaining healthy seed varieties. Many problems were pointed out from the viewpoint of work, such as the need to wash seeds soaked in salt water and dry them.

  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 separates the lower grains as healthy seeds, the separation between the grains that sink in the lower layer and the grains that rise in the upper layer is incomplete. It was impossible to select a highly reliable seed potato that was comparable to salt water selection.

  Therefore, the present invention is based on the knowledge that the pods that are full of fruits and have an outer shape are particularly excellent in germination ability, growth ability, bacterial resistance, and drought resistance, and are subjected to defatting treatment on seed pods, Next, the seeds that have been removed are slidably contacted with the screen of the specified mesh to eliminate the grains that pass through the mesh, and the grains that remain without passing through the screen of the selected screen are used as healthy seeds.
