oscillates in a vertical plane with a small swing width, and the radius of gyration of this oscillating motion is W, the weight of the entire oscillating body, W, the weight of the eccentric weight, W, and the axial center of the center of gravity of the eccentric weight. If the distance between the twists is R, the swinging radius r of the sieve box 22 can be obtained as follows.

Ｗすなわち篩箱２２およびその上に架載される物全体の
重量に対しＷ重錘重量は小さいので揺振旋回半径ｒは小

端へ自動的に移行する。Therefore, when the grain raw material containing foreign substances such as large and small branches and stalks and stems is dropped from the supply port 19 onto the wire mesh cylinder 8 that has been put into the machine case 4, the grains fall through the mesh of the wire mesh and into the discharge port 20. After passing through the introduction tube 28, the grains fall from the grain group supply port 26 of the vibrating sieve machine C to the rear of the sieve screen 30 stretched inside the sieve box 22, and large foreign substances such as branch stalks and stem culms are removed from the outer periphery of the wire mesh cylinder 8. The remaining particles on the top move forward as the wire mesh cylinder 8 rotates, are peeled off from the wire mesh surface by the rotating brush 10, and are sent from the discharge port 21 through the introduction tube 29 to the drain trough 27 provided on the upper wall of the sieve box 22 of the vibrating sieve machine C. Inserted, sink gutter 2
7 vibrates together with the sieve box 22, and large foreign substances are automatically transferred to the lower end of the drain trough 27.

が行われる。The grain cluster that has fallen onto the sieve screen 30 of the vibrating sieve machine C is caused by the small-width, high-frequency rocking motion of the sieve box 22 to remove small foreign objects such as twig stalks and stem culms that are larger than the grains and mixed in the grain cluster. is separated from the grains, and the small foreign matter remains on the sieve screen 30, flows over the sieve screen 30, is sent into the foreign matter discharge tube 32 through the opening 33, and merges with the large foreign matter flowing in from the sink trough 27, and the foreign matter is removed. The selected grains that are discharged from the discharge tube 32 and fall through the mesh of the sieve screen 30 are taken out from the discharge port 31, and in this way, grains containing foreign substances such as large and small branches, stems, and culms are removed. Separation of foreign substances and selection of grains are carried out.

穀類の篩別分級において難点となるのは大きな枝梗、茎
稈でこれらは篩別の際に網目に引掛かり網上に滞留して
篩別作用を阻害する。The difficult points in the sieving and classification of grains are the large branches and stalks and culms that get caught in the mesh during sieving and remain on the screen, obstructing the sieving action.

れをよくするために篩網を大振巾で揺動する方法や、網
傾斜を強くする方法をとるがこれらは穀粒選別の効率を
悪しく処理量に対して大きな網面積を必要とする。Therefore, in general grain sorting sieves, in order to improve the flow of branches, stems, and culms, methods are used in which the sieve screen is swung at a large swing width or the screen is made to have a strong slope. It is inefficient and requires a large screen area relative to the amount of processing.

本考案は被選別穀類原料を精選するにあたり、先ず網円

上の穀粒群は大きく飛跳することなく網上で個々粒が反
転揺振されながら移行するので細動率が良くなる。When carefully selecting grain raw materials to be sorted, this invention first uses a mesh cylindrical rotating sieve to remove large foreign substances such as branch stalks and stem culms that are mixed in the raw materials, thereby allowing the large foreign substances to remain on the screen. This eliminates the cause of the problem, and makes it possible to use a vibrating sieve machine with a small vibrating screen that rotates in the plane of the screen, which is the most effective method for sieving grains. Since it performs a vertical rotation movement with a small amplitude and a high rotational speed, grain groups on the net do not jump around a lot, and individual grains move on the net while being reversely shaken, improving the fibrillation rate. .

このように大異物除去用の回転円筒篩別機と粒選別に効
果的な振動篩機を一体に組合わせることにより従来の他
の往復揺動型精選機に比して格段に精選効果がよくなり
、また機械の外形寸法も小さく狭い空間にも配置できる
ことになる。In this way, by combining the rotating cylindrical sieve for large foreign matter removal with the vibrating sieve that is effective for grain sorting, the sieving effect is much better than other conventional reciprocating oscillating sieves. Furthermore, the external dimensions of the machine are small and it can be placed in a narrow space.

然落下させるとともに、振動篩機の篩網で分離された小
異物を大異物に合流させて排出するようにしたからこれ
ら異物の排出処理作用が容易になる。In addition, the present invention introduces the large foreign matter removed from the outer periphery of the wire mesh cylinder by the cylindrical sieving machine into a drain installed in the vibrating sieve machine and allows it to fall naturally due to vibration, and also removes the small foreign matter separated by the sieve screen of the vibrating sieve machine. Since the large foreign matter is combined with the large foreign matter and then discharged, the discharge process of these foreign matter becomes easy.

また円筒篩機と振動篩機とを一体化して密閉することに
より材料洩れ、機外発塵等も防止することができる。Furthermore, by integrating the cylindrical sieve and the vibrating sieve and sealing them, it is possible to prevent material leakage and generation of dust outside the machine.

なお、振動篩機の篩箱内に篩網を上下２段に張設し、上

下段の篩網で細かい微粉、小砂塵等を網目を通して分離
除去し、網上には精選された穀粒を残してこれを精選穀
粒排出口より取出すことかで゛きる。In addition, the sieve screen of the vibrating sieve machine is set up in two stages, upper and lower, and the mesh of the upper sieve is formed so that grains can pass through, but foreign matter larger than the grains cannot pass through. The mesh of the lower sieve screen is formed so that the grains do not pass through, and the lower sieve screen separates and removes fine powder, small dust, etc. This can be taken out from the selected grain outlet, leaving behind some grains.
