This invention relates to a rice hulling sorting device having a sorting device in which a receiving gutter is inserted into a sorting barrel which is rotatably suspended horizontally and has a number of concave portions of the size of the present invention.

(b) Conventional technology Conventionally, in the case of a hulling sorting device configured by combining a hulling section and a swinging sorter, the post-process of the grains sorted by the swinging sorter is selected by a switching valve. For example, the Special Public Interest Publication in 1973-
It is known from Japanese Utility Model Application Publication No. 5029, and the provision of a take-out valve in the swinging sorter described in this publication is known, for example, as disclosed in Japanese Utility Model Application Laid-Open No. 52-159980. By the way.

(c) Problems to be Solved by the Invention As described above, conventionally, in a hulling sorting device consisting of a hulling section and a swinging sorter, the grains sorted by the swinging sorter can be sorted by switching the switching valve. Techniques for selecting the post-stroke and techniques for providing a take-out valve in the oscillating sorter are also already known, but these techniques each individually provide a switching valve or a take-out valve. The present invention provides such a switching valve and a take-out valve in which a hulling part is mounted above one end of the wind sorting box, and a recess large enough to fit brown rice is provided on the inner peripheral surface above the other end. By organically connecting it to the hulling sorting device, which has a sorting device in which a receiving gutter is inserted into a sorting barrel that is formed in large numbers and is rotatably hung horizontally, it has good performance and efficiency. It was invented for the purpose of sorting.

(d) Means for Solving the Problems Therefore, in order to achieve the above-mentioned object, the present invention has the following features: A hulling part D is mounted above one end of the winnowing box, and an inner circumferential surface is mounted above the other end. In a hulling sorting device having a sorting device in which a receiving gutter is inserted into a sorting barrel which is rotatably suspended horizontally and has a number of recesses large enough to fit brown rice into it, The device has two sorting cylinders arranged one above the other, and the materials sorted in the receiving trough of the upper sorting cylinder are re-sorted by the lower sorting cylinder, and the upper and lower sorting cylinders are sorted again. A switching valve is installed between the rice barrel and the rice barrel to guide the sorted rice into the receiving trough of the upper sorting barrel to the brown rice removal side without being re-sorted by the lower sorting barrel. The structure is such that a take-out valve to the outside of the machine is provided on the upstream side in the receiving trough of the upper sorting cylinder to check the sorting state of the sorted materials.

(E) Function With this structure, the mixed rice of brown rice and paddy after the hulling wind sorting is fed into the upper sorting cylinder, and is lifted by the lifting action of the recess formed on the inner circumferential surface of this sorting cylinder. The materials that are sorted into the receiving gutter by this sorting action are fed into the lower sorting cylinder to be re-sorted.

In this case, the rice fed from the upper sorting cylinder's receiving gutter to the lower sorting cylinder is taken out of the machine by the take-out valve and checked to see if it has been completely sorted into brown rice. By operating the switching valve, the brown rice is guided to the unloading side and taken out without being re-sorted in the lower sorting cylinder. Therefore, the mixed rice is efficiently and efficiently sorted into brown rice and paddy by the upper sorting cylinder, the lower sorting cylinder, the take-out valve, and the switching valve.

(g) Effects of the Invention As explained above, the present invention has a hulling section mounted above one end of the winnowing box, and a size large enough to fit brown rice into the inner peripheral surface above the other end. In the rice hulling sorting device, the rice hulling sorting device is provided with a sorting device in which a receiving gutter is inserted into a rotatably horizontal sorting cylinder with a large number of recesses formed therein, and the sorting device has two sorting drums arranged vertically. The upper sorting cylinder is arranged so that the sorted items in the receiving trough of the upper sorting cylinder are re-sorted by the lower sorting cylinder, and the upper sorting cylinder is placed between the upper sorting cylinder side and the lower sorting cylinder side. A switching valve is installed in the receiving trough of the barrel to switch and guide the sorted rice to the brown rice removal side without being re-sorted by the lower sorting barrel, and the upper sorting barrel is installed on the upstream side of the switching valve. Since the system was designed with a take-out valve to the outside of the machine to check the sorting status of the sorted rice in the receiving trough, the mixed rice after the hulling wind sorting was first sorted in the upper sorting barrel. The sorted items are then re-sorted in the lower sorting cylinder, allowing for reliable and reliable sorting with good performance.
In this case, the rice fed from the upper sorting cylinder's receiving gutter to the lower sorting cylinder is taken out of the machine using the take-out valve to check whether it has been sorted properly or not. By operating the switching valve, it is possible to switch and guide the brown rice to the unloading side and take it out without having to re-sort it in the lower sorting cylinder, so there is no waste in sorting, and the grains are not damaged. This has the effect of allowing selection and suitable implementation.
