Description

The present invention relates to a seed grain sorting device that sorts seed meals suitable for raising seedlings from dried and stored raw material seeds.

Conventionally, as a seed grain sorting device such as a seed center, a wind sorter that removes light impurities from dried and stored raw rice cake, and degranulated grains and rice cakes, edible bellflowers from which the rice husks have been peeled off Grain sorter consisting of indent (claw hole) cylinders arranged in multiple stages above and below to remove sprinkled grains, waste grain layer consisting of immature soot, disposed in the next process of the grain sorter, And a specific gravity sorter that performs specific gravity sorting into three regions: a mixed grain layer in which seed meal is mixed at a ratio of about 1: 9 and a refined layer composed of high-quality fine grains with a high specific gravity. (For example, see paragraph [0005] of Patent Document 1). In other words, this kind of seed grain sorting device removes degranulated grains and waste grains that are difficult to germinate from sowing seeds when seeding and raising seedlings, and re-sorts grains with cocoons and branch-baffled seeds after defermenting, thereby yielding. It is intended to contribute to the improvement, and to provide only good buds with good germination rate as seed pods. And the degranulated grains and waste grains removed from the raw material koji are used as edible and food processing raw materials after being subjected to the rice hulling and polishing process.

However, the conventional seed grain sorting apparatus is configured to remove the deflated grains, cocoons, and branched grains in the grain sorter composed of an indent cylinder. Since the degranulated grains that have not been supplied are again supplied to the specific gravity sorter in the next step for sorting, there is a problem that the sorting accuracy is very poor such that the degranulated grains are sorted by two sorters. In addition, in the grain sorter consisting of indent cylinders, a large grain sorter with large processing capacity is used in which indent cylinders are arranged in multiple stages in order to remove degranulated grains, wrinkles, and grain with branches. There is a problem that it takes a lot of time and labor for maintenance such as cleaning required for this.

JP 2001-292605 A

In view of the above problems, it is a technical object of the present invention to provide a seed grain sorting apparatus with good sorting accuracy and excellent maintainability.

In order to solve the above-described problems, the present invention provides a wind separator for wind-selecting foreign substances from dried and stored raw material soot, and a multi-stage indentation for grain-sorting the raw soot that has been air-selected by the wind selector. Seed grain sorter equipped with a grain sorter composed of cylinders and a specific gravity sorter that is arranged in the next process of the grain sorter and tilts up and down and swings up and down a sorter made of rough surfaces. The specific gravity sorter is a fine product region having a high specific gravity on the inclined high side in the swinging direction of the sorter, a waste region made of immature rice on the low gradient side, and an immature rice cake in the middle. Formed in the mixed grain region where the seed pods are mixed and provided with a waste grain partition plate and a cocoon partition plate for partitioning each region, the refined region is defined as an excellent cocoon on the further inclined high side of the cocoon partition plate. A degranulating partition plate is provided to divide into degranulated areas where degranulated particles are mixed. Below each of the regions, a waste particle discharge basket, a mixed particle discharge basket, a refined product discharge basket, and a degranulated grain discharge basket are provided, and the degranulated powder discharge basket is provided with a grain sorting machine including a porous sorting net. The scouring machine is connected to the scouring machine while bypassing the grain sorting machine consisting of the perforated screen cylinder so that the scouring product can be directly taken out of the machine. Technical measures were taken.

Further, according to the invention described in claim 2, the technical means is adopted in which the grain sorter constituted by the indent cylinder is an indent cylinder having a two-stage configuration.

When the dried and stored raw material koji is supplied to the wind sorter, light impurities such as koji are removed and coarse selection is performed, and then it is supplied to the grain sorter consisting of an indented cylinder. Only the attached grains are selected and removed to form mixed grains consisting of cocoons and deflated grains. Then, when the mixed grains composed of the pods and defracted grains are supplied to the sorter of the specific gravity sorter, the waste grain layer composed of immature pods, immature pods and seed pods are mixed from the swaying side to the swaying side. The segregation is carried out by segregation into four regions, namely, a mixed particle layer, a refined layer composed of high-quality koji with a high specific gravity, and a degranulated layer in which high-quality koji and degranulated particles are mixed. At this time, the high-quality cocoon discharged from the degranulated culm and the degranulated particles mixed with the degranulated particles are supplied to a particle sorting machine comprising a porous sorting net in a later process, and the excellent cocoons and the deflated particles are supplied. After being separated and sorted, the excellent rice cake is taken out of the machine through a refined grain masher. On the other hand, the superior rice cake discharged from the refined waste basket is taken out of the machine directly from the refined cerealing machine, bypassing the grain sorting machine consisting of the porous sorting net cylinder, so the grain sorting consisting of the porous sorting net cylinder in the subsequent process The machine can adopt a machine with a small processing capacity, and the grain sorting machine consisting of an indent cylinder arranged in the previous process does not remove the degranulated grains, so the sorting accuracy is good and the processing capacity is small. Since a thing can be employ | adopted, the miniaturization of the whole structure of a seed grain sorting apparatus is attained.

In addition, since the grain sorter composed of indented cylinders has a two-stage configuration, it only needs to have a function of sorting and removing only the grains with wrinkles and branches, and by adopting one with a small processing capacity, The labor and time required for maintenance such as cleaning can be greatly reduced.

The inventors of the present invention have a problem in terms of ability and accuracy of a grain sorter composed of indented cylinders. Then, if it is set as the structure which sorts the degranulated particles mixed in a granule in a specific gravity sorter, on the sorting board of this specific gravity sorter, 4 of a waste grain layer, a mixed grain layer, a refined layer, and a defatted grain layer It was found that segregated in one region (as shown by the crosses in FIG. 2, the degranulated particles are distributed on the rocking side). Furthermore, if this defatted particle layer is passed through a particle sorting machine comprising a porous sorting mesh cylinder, it is possible to sort and remove the degranulated particles with high accuracy, and eventually a grain sorting machine comprising an indent cylinder in the previous process. It was thought that downsizing of the overall configuration could be realized.
