挟雑物を孔から漏下させる。(Function) The proposed shutter device as described above is suitable for wheat,
When grain size is small, such as rice, or when there are few impurities, use the part without holes for the bottom holes of No. 1 and 2 gutters. For large grains such as soybeans, use the perforated holes to match the bottom holes of No. 1 and 2 gutters to allow soil and small debris to leak through the holes.

このように、閉塞、目抜きと１，２番樋の底孔

９は操縦席を示す。 Leakage including grains that have fallen from the oscillating sorting machine is sorted by a winnowing blower fan 11 and a suction fan 12 at the end of the handling cylinder, and the grains are transferred to the first gutter 14 and the second gutter by the blower fan 13. The grains that fell into the second gutter 15 and the grains that fell into the first gutter 14 are transferred to the grain frying conveyor 1.
The second paddy is transported to the paddy tank at step 6 and returned to the oscillating sorting board 9 through the thrower cylinder 17. 18 is a crawler equipped with a threshing machine;
9 indicates the cockpit.

本案は以上のような脱穀機における１，２番樋
の改良に関するものである。 This proposal concerns the improvement of the 1st and 2nd gutter in the above-mentioned threshing machine.

第２図においてシヤツター板２２には左方から
抜き孔２１、目抜き孔２４、網孔２３、孔無し２
５、抜き孔２１、目抜き孔２４、網孔２３、孔無
し２５の順に孔が設けられている。 In FIG. 2, the shutter plate 22 includes, from the left, a punched hole 21, a punched hole 24, a mesh hole 23, and a hole 2 without a hole.
5. Holes are provided in the order of punched holes 21, punched holes 24, mesh holes 23, and no holes 25.

に合わせることができるものである。 Therefore, for the bottom holes 26 and 27 of the No. 1 and 2 gutters where the screw conveyors 14a and 15a are located, the holes of the shutter plate 22 are changed from the closed state with no holes to the net hole 23,
The openings 24 and 21 (ie, the start) can be aligned in this order.

来るようになる。 Since the shutter plate 22 is constructed as described above, when there are small particles such as wheat or rice or there are few impurities, the shutter plate 22 can be used without a hole 25 or with a mesh hole 23 in the bottom hole 26 of the 1st and 2nd gutter. Used according to 27. For large grains such as soybeans, use the mesh holes 23 or perforations 24 to match the bottom holes 26 and 27 of the 1st and 2nd gutters.
Allow soil and small debris to leak through the holes. When cleaning is desired, the holes 21 and 21 are aligned with the bottom holes 26 and 27 and used. Depending on whether the phases of the punch holes 21 and 21 are shifted or matched, the first and second gutter can be cleaned sequentially or the first and second gutter can be cleaned simultaneously.

で大豆用に一斉に変更できるものである。 In other words, when grain size is small such as wheat or rice, or when there are few impurities, the part without holes is used to match the bottom hole of the gutter, and when grain size is large such as soybeans, the part with perforations is used as the gutter. Use according to the bottom hole. In this way, while soybeans and the like are transported by the screw conveyor, soil and small impurities are allowed to leak out, resulting in a significant improvement in sorting performance. The spacing between the two perforated holes matches the spacing between the first and second gutter, so it can be changed all at once for soybeans just by sliding.
