It is connected to 341.

Therefore, the paddy in the paddy tank (]) is supplied to a pair of de-aging rolls (2) at the supply port, where it is rubbed down, sorted in the wind sorting section (B), and the rice is removed from the rice frying tube (31K). supply tank (T)
It is put inside. This thrown-in rice is transferred to the transfer device (b).
) is transferred to the supply side +X) and falls into the primary sorting cylinder (5) one after another. While moving toward the discharge side (Y) while flowing due to the scooping action of the depression (a), the brown rice and a portion of the paddy are scooped up and placed in the receiving trough (8).
) and flow into the secondary sorting cylinder (6) from the communication gutter 01/(+11) to perform the secondary sorting action. Although it is similar to the cylinder (5), this secondary sorting cylinder (6) is adjusted so that only brown rice is scooped up into the receiving gutter (9).

Then, the paddy that was not scooped up by the primary sorting cylinder (5) enters the paddy return road fin from the discharge side fy) and the bottom plate (1).
1 and flows down from the supply port G to the de-sexing roll (2) and is re-extracted. One part of the brown rice and one part of the paddy that were not scooped up by the secondary sorting cylinder (6) flow through the circulation path QZ and are lifted up again by the sliding rice lifting cylinder (3), where they are received. The brown rice scooped up into the gutter (9) flows from the channel (13) onto the flow plate 041, and after wind selection in the wind selection section (B), it is taken out of the brown rice grain lifting machine (4). .

At that time, if the amount of rice that slides down from the paddy tank (1) through the supply port 6 (through the de-stretching roll (2) increases), the amount of dropped rice stored in the supply tank (T) increases. The surplus lifted from the grain cylinder (3) overflows from the bath outlet t+S, flows into the sensing case (S) through the bath outlet cylinder ■, and accumulates on the sensing valve QIl at the bottom, causing it to be activated. , this operation is performed by interlocking the adjustment plate to adjust the opening degree of the supply port +25) to the narrow side, and
) and the capacity of the rotary sorting section (0) are balanced, and the hulling and sorting work is continuously operated.

By the way, if foreign matter is mixed in the paddy put into the paddy tank (1), the rotation of the primary sorting cylinder (5) above the inner circumferential surface of the primary sorting cylinder (5) will cause it to rise.・The downward flow and the transition from the supply side (fx) to the discharge (all (y)) make an abnormal noise, and especially in the case of metals, the abnormal noise is strong enough to immediately detect the presence of foreign matter. If you move the upper end of the operating rod c31) downward along the elongated hole +3 (1), the switching plate that was blocking the outlet ■ will be in the state shown by the imaginary line in Figure 2, and the outlet (support) will be opened. At the same time, the paddy return path (2) is connected, and the foreign matter and paddy that are about to be discharged from the discharge side (Y) of the primary sorting cylinder (5) are removed from the extraction port ■
It fell from the foreign body and passed through the foreign object removal tube (D) to the additional gutter 04).
It will be taken out of the aircraft.

As described in the following two, the present invention is provided with a de-sexing section above and a wind screening section below, and a large number of depressions are formed on the inner circumferential surface on the side of the de-sexing section, and one end is covered. A rotary sorting section is equipped with a rotatable horizontal sorting cylinder whose one end is a supply side for sorted grains and the other end is a discharge side, and a receiving gutter is installed to take out the sorted section scooped up by the above-mentioned depression. The paddy return path is installed so that the side is adjacent to the dehulling section, and the discharge side of the sorting cylinder of the rotary sorting section is connected to the dehulling section. Since it is made switchable so that it can communicate with the paddy, if there is any foreign matter mixed in the paddy, the foreign matter passes through the dehulling section along with the paddy, and after being subjected to wind screening, it is supplied to the rotary sorting section and then to the sorting section. When the paddy and brown rice are sorted in the sorting cylinder, foreign objects come into contact with the inner circumferential surface of the sorting cylinder and make a continuous noise, allowing the operator to immediately and reliably detect the presence of foreign objects. Using the operating lever, the switching plate switches the paddy return path to the outside of the machine (IIll) to prevent foreign matter from being taken out from the discharge side of the sorting cylinder and supplied to the next process, thereby causing damage to various parts. It is possible to perform work with high efficiency without straining the user.

Moreover, if a foreign matter removal tube is provided in the space between the desalting section and the rotary sorting section as in the embodiment, and one is placed in parallel with a sensing casing for sensing the excess amount of lifted rice, the above-mentioned result can be achieved. This allows the machine to be extremely compact while still being able to reliably remove foreign objects.

Indication of the incident Patent Application No. 1988-23774 2. Name of the invention Paddy type sorting device (41 yo completed) Address: 428 L-R Nami, Okayama City Name (516) Seirei Kogyo (1: Company details 1, Name of the invention: Rice hulling sorting device 2, Claims: 1 direction, 4 sections, rotating selection) Separate segmented body - Uchiya ζ [Surface-opened surijin - rice receiver 1゜3, Detailed description of the invention [Field of industrial application] 11 The present invention desexes paddy in a desexing mechanism and wind-sorts it. The present invention relates to a hulling sorting device that wind-sorts the rice husks in a section, and then sorts and extracts only brown rice from the mixed rice after this wind sorting. [Prior Art] Conventionally, this type of hulling sorting device In many cases, a rocking type sorting mechanism was used to sort brown rice, but this rocking type sorting mechanism was large and had disadvantages such as high vibration and noise, so it was not possible to use it before. Unexamined Japanese Patent Publication (1973) as a technology
Publication No. 24745 uses a rotary sorting mechanism that is equipped with a brown rice receiving trough inside a horizontal rotary sorting cylinder with a number of depressions formed on its inner circumferential surface to sort brown rice from mixed rice after descaling. I am proposing one thing to do. [Problems to be Solved by the Invention] However, the rice hulling and sorting device described in this publication supplies the mixed rice to one end of the sorting cylinder close to the dehulling mechanism in its rotary sorting mechanism, and The other end is the paddy discharge side, and the paddy discharged from the discharge side is transferred back to the dehulling mechanism to be re-dehulled through a transfer means provided outside the sorting cylinder. Because of this, the overall size of the hulling and sorting device is increased by the amount that the transfer means for returning and transferring the rice discharged from the sorting cylinder to the dehulling mechanism is provided on the outside of the sorting cylinder, In other words, there is a drawback that the rice hulling sorting device becomes large in size. On the other hand, the rice supplied to the dehulling mechanism contains foreign substances such as pebbles, wood chips, or metal pieces. Since the paddy discharged from the sorting cylinder is directly transferred to the de-processing mechanism, the foreign substances mixed in the paddy are not taken out of the machine and are de-processed together with the de-processed paddy. The process of entering the sex mechanism, desexing the paddy, passing through the rotary sorting mechanism, and then entering the desexing mechanism again is repeated many times. Moreover, the amount of foreign matter that continues to circulate indefinitely is , the number increases in proportion to the time of the de-ffff sorting work, so the de-ffffing mechanism, the sorting cylinder, various transfer means, etc. are easily damaged or damaged early by foreign objects, resulting in low durability. was there. An object of the present invention is to solve the above-mentioned problems in a hulling and sorting device that uses a rotary sorting mechanism for sorting brown rice. [Means for solving the problem] For this reason, the present invention provides a screen for sorting rice husks for mixed rice from the dehulling mechanism at the lower part of the dehulling mechanism, and a box on the side of the hulling mechanism. A rotary sorting mechanism equipped with a brown rice receiving gutter with an open top surface is disposed in a horizontal rotary sorting cylinder with a large number of depressions formed on the inner peripheral surface, and one end of the sorting cylinder in the rotary sorting mechanism is provided. In the hulling and sorting device configured to supply mixed rice from the wind sorting box, the other end of the sorting cylinder of the rotary sorting mechanism on the hulling mechanism side is formed on the paddy discharge side. This discharge side is connected to the paddy supply section of the hulling mechanism through a paddy return passage, and in the middle of the paddy return passage,
The structure is such that a means is provided for removing foreign matter mixed into the paddy out of the paddy return passage. [Operations and effects of the invention] In this way, the other end of the sorting cylinder of the rotary sorting mechanism that is close to the dehulling mechanism is used as the paddy discharge side, and the paddy return passage is connected to the paddy supplying section of the dehulling mechanism from the discharge side. Because of the communication through the separation cylinder, there is no need to provide a transfer means on the outside of the sorting cylinder to transfer the paddy to the dehulling mechanism as in the prior art, so a rotary sorting mechanism can be used for sorting brown rice. When used, the width and height of the entire hulling and sorting device can be reduced. Moreover, by providing a foreign matter removal means for taking out foreign matter mixed into the paddy out of the paddy return passage from the discharge side of the sorting cylinder to the dehulling mechanism, the sorting cylinder Publication in? Foreign matter such as pebbles or metal pieces that are discharged together with the paddy from all the grains (foreign matter such as pebbles or metal pieces) can be taken out of the paddy return passage by the foreign matter removal means before being returned to the de-sexing mechanism, so unlike the prior art described above, the paddy It is possible to prevent foreign substances mixed in the rice from circulating forever between the culling mechanism and the rotary sorting mechanism together with the paddy.Therefore, according to the present invention, the hulling and sorting method using the rotary sorting mechanism for sorting brown rice can be prevented. While it is possible to downsize the device,
Since it is possible to reduce the damage and breakage of the dehulling mechanism, sorting cylinder, etc. due to foreign substances such as pebbles or metal pieces mixed into the rice, it has the effect of improving the durability of the hulling and sorting device. [Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 shows a longitudinal sectional front view of the entire hulling and sorting device. This hulling and sorting device includes a rectangular wind sorting box B and The entire system is composed of a de-ninning mechanism A mounted on the top surface of the screening box B, and a rotary sorting mechanism C installed next to the de-nexing mechanism A.

Reference numeral 27 denotes a paddy return passage formed in the paddy supply tank 1 by the upper surface of the bottom plate 1' on the rotary sorting mechanism C side of the paddy supply tank 1 and a downward U-shaped cover plate 27' in cross section. The upper end of the rice return passage 27 opens at the lower part of the discharge side Y of the secondary sorting cylinder 5, and the lower end communicates with the supply port 25 to the stripping roll 2. A foreign matter removal port 28 is provided in the rice return passage 27 as one embodiment of foreign matter removal means. This foreign matter removal port 28 is always closed by a rotary valve plate 29 provided in the rice return passage 27, and when taking out foreign matter, the valve plate 29 is moved from the valve plate 29 to the cover plate 27'. The foreign matter removal port 28 is opened by holding an operating rod 31 that protrudes through the long body 30 and rotating upward. The lower end of the foreign matter removal tube communicates with a removal fji 34 formed in a cover 33 that covers the transmission device E on the side surface of the wind selection box B. However, when paddy is supplied to the paddy supply tank 1 during work,
The mixed rice desexed by the desexing mechanism A is wind sorted in a wind sorting box B to remove the chaff, and then sent to the mixed rice supply tank T in the mixed rice lifting cylinder 3. Supply tank T
