Description

Detailed Description of the Invention "Industrial Application Field" The present invention provides a grain-flipping spiral body in which a spiral blade is wound around the outer periphery of a cylindrical body in an outer shell body, and a grain-flipping spiral body that is concentrically inserted into a large number of grains. The present invention relates to a vertical grain sorting machine which houses a sorting net body provided with small holes and feeds unsorted grains to the base of a grain lifting spiral body and sorts the grains while frying the grains.

"Prior Art" In a conventional vertical grain sorter l, the inside of the outer shell z is partitioned from above into an upper partition plate 3 and a lower partition plate 4. The upper partition plate 3 receives the grains, and the lower part On the partition plate 4, small grains were received and scraped out to the outside by upper scraping blades 5 and lower scraping blades jII6, respectively.

In the vertical grain sorter l, the size of the small holes 8 in the sorting net 7 must be changed from time to time depending on the grains to be fed. After removing it, the ceiling board 9 was opened and pulled upward.

However, in such a conventional vertical grain sorter, it is troublesome to remove the lower scraping blade 6 every time the sorting net 7 is replaced, and sometimes the user forgets to attach it. There was a problem that the tightening was loose and it could come loose during operation, causing damage.

Further, due to the structure, there is a limit to the accuracy that can be expected, and it is difficult to manufacture the lower scraping blades 6 on the upper surface of the lower partition plate 4 or on the inner and outer peripheries.

The present invention has been made by focusing on such conventional problems, and the lower scraping blade for scraping out small grains is placed completely on the peripheral edge of the grain receiving tube corresponding to the conventional lower partition plate or on the peripheral edge elevation. The purpose of this invention is to provide a vertical grain sorting machine that can be slid into contact with and rotated around the grains, and which does not leave small grains behind.

"Means for Solving the Problems" The gist of the present invention for achieving the above object is to provide an external device equipped with a supply hopper for supplying unsorted grains and a storage tank for storing spermatozoa outside the body. A vertical shell body for sorting grains is housed inside the shell body so as to be able to rotate relative to each other. In the type grain sorter, the grain sorting machine is provided surrounding the base of the grain lifting spiral, and has a cylindrical peripheral edge elevation following an outwardly opened horizontal peripheral edge at the upper end opening, and has a cylindrical peripheral edge elevation surface that is continuous with the horizontal peripheral edge that opens outward, and the upper end opening has a cylindrical peripheral edge elevation. On the one hand, a grain receiver is provided for receiving sorted grains and supplying them to the grain frying spiral.

The unsorted grains fed from the supply hopper are placed in the grain receiving cylinder provided at the base of the lifting-a spiral body, and the grains are placed in a grain guide cylinder of approximately the same diameter that rotates in the same direction as the sorting net. The grains are pushed downward by the guiding blades, and are sent through a plurality of grain guiding ports provided on the lower skin surface of the grain guiding cylinder to the starting end of the lifting spiral body which rotates in the opposite direction to the sorting net. will be sent.

The grains raked up by the husk spiral are thrown outward and subjected to a sorting action by the sorting net, and small grains pass through the sorting net and are eliminated, while grains that do not pass through the sorting net are removed. The grain rises as it is and is stored in a storage tank.

The unsorted grains fed from the supply hopper are pushed down by the grain guiding blades and introduced from the grain guiding port, so that the grains scraped up by the spiral blades of the grain lifting helix and the grains from the feeding hopper are The supplied grains do not interfere with each other and are smoothly fed, increasing the amount of grains fed.

The lower scraping blade, which is fixed on the partition disk of the grain guiding cylinder, is arranged so as to be in contact with the upper peripheral edge of the grain receiving cylinder and the peripheral edge elevation. When it rotates, all of the small grains that fall and accumulate on the periphery are scraped out and do not remain in the body.

"Example" Hereinafter, various embodiments of the present invention will be described based on the drawings.

1 and 2 illustrate a first embodiment of the invention.

The vertical grain sorting machine 10 includes a shell body 11 that is vertically installed, and a shell spiral body 14 formed by winding a spiral blade 13 around the outer periphery of a cylindrical body 12, and a shell body 14 that is concentric with the grain shell body 14. A sorting net 16 that surrounds the outside and has a large number of small holes 15 is housed therein.

The raised shell spiral body 14 and the sorting net body 16 are driven to rotate in opposite directions to each other by a motor 18 with a speed reducer provided at the lower part of a base plate 17 that partitions the interior of the outer shell body 11 into upper and lower parts.

A supply hopper 19 for supplying selected rice 311 grains is provided outside the shell body 11, and a storage tank (not shown) for temporarily storing the fine grains is provided in one head.

A grain receiving cylinder 20 is erected on the upper surface of the base plate 17, and has a cylindrical shape and a tapered part 21 having a truncated conical bottom. Then, a cylindrical peripheral edge elevation 22a is formed. The supply hopper 19 has an opening 19a near the center of the grain receiving cylinder 20.

As shown in FIG. 2, the partition disk 32 has a circular outer periphery, and as shown in FIG. The outer periphery has a size that corresponds to the inner periphery of the peripheral edge elevation 22a of the grain receiving cylinder 20. Further, as described above, the lower scraping blade 33 engages with the engagement notch 16b of the sorting net 16 to transmit the rotation of the sorting net 16 to the grain guiding cylinder 30,
The small grains that have passed through the small holes 15 of the sorting net 16 and have fallen are discharged to the outside from the small grain discharge pipe 11a.

On the other hand, a plurality of grain guiding ports 34 are bored in the lower end of the grain guiding cylinder 30, as shown in each country. As shown in FIG. 1, these grain guide ports 34 have their upper line 34a located far below the lower edge of the opening 19a in the grain receiving cylinder 20 of the supply hopper 19.
