Description

DETAILED DESCRIPTION OF THE INVENTION (a) Industrial application field The present invention comprises a hulling section with a vertical stirring shaft, and a wind sorting section below to sort out the scraped material from the hulling section. The present invention relates to a vertical rice huller which is intended to perform the sorting process well and effectively in the case of rice hulling.

(b) Conventional technology In the case of conventional rice hulling machines, for example,
As shown in Publication No. 7, the take-off shaft is of a so-called horizontal type and is horizontally installed so that it can be rotated freely, and the material that has fallen off at the hulling section is scattered radially around the take-off shaft that is installed horizontally. Because they fall, even if they scatter in a radial pattern, if they fall, they become aggregated and flow into the wind sorting section in this aggregated state, which has the disadvantage that they cannot achieve a sorting effect. That's why.

(c) Problems to be Solved by the Invention Therefore, the present invention takes advantage of the dispersion phenomenon in which the debris at the hulling section scatters and falls in a radial manner, without restricting the leveled state caused by this dispersion phenomenon. Let it flow into the wind sorting section below, thereby eliminating the disadvantages of the conventional hulling machine with the scale removal shaft installed horizontally, and making it possible to perform good and effective sorting in the wind sorting section. It is intended to be provided for the purpose of

B) Alternative means for solving the problems The present invention attempts to achieve the above object by taking the following measures.

The brown rice and rice husks are dehulled by the above-mentioned rubbing action and scattered radially from the periphery of the double demolition cone (125Ql). Due to the centrifugal force, the brown rice and rice husks are scattered far away and received in a dispersed state. The brown rice falls to the lower layer to be received by the chamber (2)), and the rice husks are in the upper layer and flow into the ventilation section (2), where they are leveled to the full depth. The selected rice husks pass through the suction pipe and are discharged from the machine through the suction fan, while the brown rice flows from the lower part of the wind selection room into the grain lifting tube and is lifted into an appropriate container. .

(g) Effects of the Invention As described in detail above, the present invention provides a structure in which the dehulling shaft of the hulling part for dehulling paddy is rotatably installed vertically, and the sliding shaft from the hulling part is provided below the hulling part. A wind sorting section for sorting out the fallen materials is provided, and a receiving section is formed between the hulling section and the wind sorting section to receive the fallen matter and flow it into the wind sorting section in a leveled state. Because of this structure, the paddy supplied to the huller is slid down around the vertically installed dehulling shaft, and the scraped material is scattered radially in all directions by the centrifugal force caused by rotation. At this time, the brown rice was scattered farther than the rice husks due to the centrifugal force mentioned above, separated from the rice husks, and fell, so that the brown rice was in the lower layer and the rice husks were in the upper layer and were leveled to the full depth. Since the rice husks flow into the wind sorting section in such a state, the sorting and removal of the rice husks in the wind sorting section is good and effective, improving the wind sorting effect and making it possible to extract only brown rice.
