本発明は石抜選別機の改良に係るもので、穀粒中から小
石を濃縮選別した穀粒混合の粒群を更に濃縮精選するた
めに工夫したものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a stone removal sorter, which is devised for further concentrating and selecting a mixed grain group in which pebbles have been concentrated and sorted from grains.
従来の公知例は凡て精選機の底板およびその周辺におい
て作用する風が上方ないし後方に向って斜上方向に吹く
だけで穀粒の散乱を防ぐ作用がないので比重選別によっ
て小石層の上に浮遊する穀粒が一旦分離された小石層中
に再び乱入し、ついに高精度の選別が期待されないのが
共通の欠陥になっている。In all conventional known examples, the wind acting on the bottom plate of the sorting machine and its surroundings only blows diagonally upwards or backwards, and does not have the effect of preventing the scattering of grains. A common defect is that floating grains re-enter the pebble layer from which they have been separated, making highly accurate sorting impossible.
本発明は精選機の底板上に浮遊する穀粒層を制圧状に後
方に向って整流返送させる送風作用を発生させるために
精選機の前上部付近に吹管を臨設し精選機の底板上の穀
粒に対し後方に向って制圧状に吹掃し予備選別行程とし
ての後方選別板に整流返送して従来至難とされていた小
石の高精度選別を可能にするものである。In the present invention, a blowpipe is provided near the front upper part of the separator to generate a blowing action that rectifies and returns the grain layer floating on the bottom plate of the separator in a suppressed manner. The grains are swept backwards in a compressed manner and then rectified and returned to the rear sorting plate as a preliminary sorting process, making it possible to perform high-precision sorting of pebbles, which has been considered extremely difficult in the past.

回して吸風路７から循環吸入する。To explain the present invention in terms of a case, a sorting frame 2 equipped with a forward-facing porous wall sorting plate 1 is vibrated back and forth at an elevation angle β on the same side that is greater than an elevation angle α of the sorting plate 1.
A wind chamber 5 of a wind turbine 4 which blows air from below through the pores 3 of the porous wall is provided in the lower part of the window. The blown wind is bypassed and circulated and inhaled from the air intake path 7.

機１０の先端の小石落下部は小石排出口１８のある小石
排出管１９に隣設される。A base line 9 is placed on the side of the pebble outlet 8 in the center of the front wall of the sorting frame 2, and a sorting machine 10 that rotates up and down at an elevation angle γ on the same side that is equal to or greater than the elevation angle α of the sorting plate 1 is protruded from the wind turbine 4. Branch air path 11
A blowpipe 12 is installed near the front upper part 13 of the sorting machine 10. The bottom plate 14 of the sorting machine 10 is formed as a porous wall and communicates with the branch air passage 11. The porous wall section 16 is also connected to the picture air passage 1γ which communicates with the branch air passage 11, and the pebble falling part at the tip of the sorting machine 10 is placed adjacent to the pebble discharge pipe 19 having the pebble discharge port 18.
選別板１の上方には供給口２０を、また選別板１の後端
には排穀口２１がある。A supply port 20 is provided above the sorting plate 1, and a grain discharging port 21 is provided at the rear end of the sorting plate 1.

する。The grains mixed with pebbles are supplied from the supply port 20 onto the sorting plate 1 of the sorting frame 2, and the grains with low specific gravity float to the surface by the wind blowing from below to upward through the porous wall pores 3 of the sorting plate 1 by the windmill 4. Grains and pebbles with a large specific gravity are deposited on the sorting plate 1, and the grains and pebbles separated into upper and lower layers are forwarded diagonally upward by the vibration of the sorting plate 1 at a rocking angle of β and are sorted. Frame 2
The floating grain layer is influenced by the angle of repose and is discharged from the discharge port 21 along the elevation angle α.

１９を経て小石排出口１８に排出する。The pebbles concentrated at the front end of the sorting frame 2 have low sorting purity and still contain a large number of grains, so they are further taken out to the forward-protruding sorting gutter 10 for secondary sorting. However, in the selection chamber of the present invention, first, the grains floating on the pebble layer by the wind blowing up from the pores 3 of the bottom plate 14 are exposed to the blast air from the blast hole 15 of the soft pipe 12 installed in the front upper part 13. Since only the grains are blown backwards and blown back to the rear sorting plate 1 while being controlled so that they are not scattered, only pebbles remain in the selection gutter 10 and are transferred from the end of the selection gutter 10 via the pebble discharge pipe 19 to the pebble discharge port. Discharge at 18.

されるものである。The concentrated mixed grains concentrated at the front end of the sorting plate 1 are sent to the pebble outlet 8.
At the same time, only the grains float up and are sent back to the sorting plate 1. Only the pebbles fall from the end of the sorting gutter 10 and are discharged. The grains are drained and discharged from the grain discharging port 21, where they are separated and sorted into grains and pebbles with high accuracy.

著である。In short, the present invention is novel in that it blows down the wind with precise directionality backwards from the front upper part of the selection chamber 10 toward the bottom plate 14 of the selection chamber 10, and this makes it possible to perform the selection which has been considered extremely difficult in the past. The effect is extremely remarkable.
なお、本発明の軟管は管の先端に吹口を設ける場合もあ
