The gate valve, which can be adjusted near and far from the inner circumferential surface, is extended at an angle [2] Since the configuration is 1-7, the overall width of the inside including the receiving gutter and gate valve can be made sufficiently wide, and the screening effect can be improved. This allows the brown rice to flow smoothly into the receiving trough, ensuring good conveyance by the rice conveyor, and by adjusting the gate valve, the degree of sorting can be adjusted well. The rotary sorting cylinder and the spiral conveyor have a structure that allows them to be driven separately, making it possible to construct the spiral conveyor in a small size.The mixed pot after hulling can be reliably and well sorted, and the structure is simple and suitable. It has the advantage of being able to be implemented in many ways.

Description 1, Title of invention Rotary grain sorting device 2, Claims (1), Recessed part on inner peripheral surface A rotary sorting cylinder having a plurality of recesses is installed horizontally, and one end of the rotary sorting cylinder is equipped with a supply section for a mixture of brown rice and paddy, and the other end is equipped with a paddy discharge section, In a rotary grain sorting device comprising a brown rice receiving trough with an open top surface extending in the axial direction of the sorting cylinder in the rotary sorting cylinder, the sorting cylinder is one of the left and right side plates of the brown rice receiving trough. A rotary grain sorting device characterized in that a freely adjustable opening plate is provided at the upper end of the side plate on the side plate for scraping up mixed rice. 3. Detailed description of the invention [Field of industrial application] The present invention relates to a sorting device for sorting brown rice from mixed rice after hulling. [Prior art] A rotary sorting cylinder having a number of concave portions formed on its inner circumferential surface is installed horizontally. A feeding section for a mixture of brown rice and paddy is provided at one end of the rotary sorting barrel, and a paddy discharge section is provided at the other end. The rotary grain sorting device is equipped with an open brown rice catcher.
This is disclosed in Japanese Unexamined Patent Publication No. 49-24746 as a prior art. In this rotary grain sorting device, the mixed rice supplied into the sorting barrel is scraped up to a height by the rotation of the sorting barrel, and then falls to the bottom, forming a layer as it moves toward the discharge side. In the process, the brown rice of the mixed rice is lifted up to a relatively high position while being fitted in the recess and then falls, and the paddy of the mixed rice falls from a lower position than the brown rice. The brown rice that falls from a high position is caught in the brown rice catcher and taken out.
In this case, the height at which brown rice and paddy fall varies depending on the variety and/or moisture content, supply amount, etc., so the above-mentioned prior art publication It is proposed that only brown rice enters the brown rice receiving gutter by adjusting the rotation of the brown rice receiving gutter in the rotational direction of the sorting cylinder. [Problems to be solved by the invention] However, such However, since the brown rice receiving gutter is large and heavy, it is difficult to adjust the rotation of the brown rice receiving gutter in the rotational direction of the sorting cylinder. Moreover, since the opening width of the brown rice receiving gutter in the rotational direction of the sorting barrel is always constant, the brown rice receiving gutter can be used for sowing mixed rice inside the sorting drum between its left and right sides. If you adjust the rotation so that the side plate on the side is lowered, the side plate on the opposite side of the side for sowing mixed rice in the sorting barrel will also rotate in the same direction, so that the brown rice that is lifted from the mixed rice in a state that is stuck in the four parts will be removed. Among them, small grains do not fall into the brown rice receiving gutter (a phenomenon occurs in which they pass through the gap between the side plate on the opposite side to the side plate on the scraping side and the sorting cylinder and return to mixed rice again). Therefore, there was a problem in that the sorting ability was reduced.The present invention eliminates the problem in the rotary grain sorting device disclosed in the publication as the prior art. For this reason, the present invention provides a rotary sorting cylinder having a plurality of concave portions formed on its inner circumferential surface, which is installed horizontally, and a feeding section for mixed rice of brown rice and paddy at one end of the rotary sorting cylinder. A rotary grain sorting device comprising a paddy discharge section installed at the other end, and a brown rice receiving trough with an open top extending in the axial direction of the sorting barrel inside the rotary sorting barrel. In this invention, an adjustable adjustment plate is provided at the upper end of the side plate on the mixed rice sowing side in the sorting barrel among the left and right side plates of the brown rice receiving trough. [Effect] In other words, with this configuration, in order to allow the brown rice picked up by the rotation of the sorting cylinder to enter the brown rice receiving trough while being stuck in the concave portion, the mixing inside the sorting cylinder in the brown rice receiving trough is It is only necessary to adjust the adjustment plate installed on the side plate on the rice scraping side, and there is no need to rotate the entire brown rice receiving trough as in the prior art, so it is possible to Adjustment so that only brown rice enters the brown rice receiving trough can be made extremely easily, freely, and minutely in response to changes in the amount of wood, etc., and the structure can be made extremely simple, and
This makes it possible to reduce the weight. Moreover, according to the present invention, it is possible to adjust so that only brown rice enters the brown rice receiving trough in response to changes in the variety of grain to be handled and/or moisture content, supply amount, etc., only by adjusting the adjusting plate. The position of the side plate on the side opposite to the mixed rice sowing side in the sorting cylinder of the left and right side plates of the receiving gutter does not shift during adjustment, and the upper end of the side plate on the opposite side is the mixed rice that falls into the sorting cylinder. Since the grain can be always located at a part far from the flowing part of the grain, it can be adjusted to changes in the variety of grain to be handled and/or the moisture content, supply amount, etc., so that it will not fall into the brown rice receiving trough as in the prior art. (The amount of brown rice that passes through this will decrease; in other words, the amount of brown rice that falls into the brown rice catcher will become thicker (reduced) by adjusting for changes in the grain variety handled and/or the moisture content supply amount, etc.) [Example] Below, drawings of an example in which the present invention is applied as a sorting device in a rice hulling sorter will be described. C indicates the wind sorting section. In the wind sorting section C, a No. 2 conveyor 5, a mixed rice conveyor 6, a paddy conveyor 7, and a brown rice conveyor 8 are installed, and at one end of the wind sorting section C, a suction dust extractor 9 is installed. A suction port 10 is opened so as to communicate and suck atmospheric air from the suction port 11.12 to the upper side of the conveyor.

A brown rice thrower 14 is installed at one end of the brown rice conveyor 8.
Further, a paddy thrower 17 is connected to one end of the paddy conveyor 7, and a paddy supply hopper 1 is connected to the upper surface of one end of the wind sorting section C.
A rice huller having a rice huller 5 and a culm removal roll 16 is mounted, and the upper end outlet of the rice thrower 17 is made to look into the rice grain supply bomber 15. A rotary grain sorting device E is mounted on the upper surface of the other side of the wind sorting section C. This rotary grain sorting device E includes a case 18 and a sorting cylinder with both ends open horizontally installed inside the case 18. The sorting cylinder A consists of four driving wheels 19 and 19 arranged at the lower portions of both ends on both the left and right sides when viewed from the axial direction of the sorting cylinder A.
It is placed so as to be in contact with the holder, and there are presser rings 20.
20 are rotatably supported in contact with each other, and a large number of recesses 1 large enough to fit brown rice are formed on the inner circumferential surface of the sorting cylinder. B indicates a brown rice receiving trough that is disposed within the sorting cylinder A substantially parallel to the axial direction of the sorting cylinder A, and the brown rice receiving trough B is of an open top type and has bent portions (A) on both left and right sides thereof. (b) The brown rice receiving channel B is provided with side plates 3 and 4 that are more inclined outward and has a funnel-shaped cross section, and both ends of the brown rice receiving channel B are fixed to the case 18. Inside B, a spiral conveyor C is provided at a position lower than the center point 0 of the sorting cylinder A. In a tank 25 provided above one end of the case 18, the second end of the mixed rice thrower 13 is exposed to the rising sun,
The lower outlet 26 of the tank 25 is made to look into the supply side (c) of the sorting cylinder A at one end. A gutter 27 communicating with the paddy conveyor 7 is provided below the discharge side (d) at the other end of the sorting cylinder A. The outlet end of the brown rice receiving trough B in the sorting cylinder A is communicated with the brown rice conveyor 8 via a falling trough 28 and grain flow plate 29. In addition, by belt transmission from a pulley 32 fitted to the output shaft of a motor provided in the wind sorting section C to the rotating shaft 30 of the drive wheel 19, 19, the sorting cylinder A is moved in the left direction of the arrow (bo). At the same time, the held is also transmitted to the shaft 31 of the spiral conveyor C in the brown rice receiving trough B. l! ! 1!
The rotary conveyor C is driven to rotate. And, among the side plates 3 and 4 in the brown rice receiving channel B,
Both side plates 3 are arranged so that the side plate 3 on the right side, that is, on the side of raking up mixed rice in the sorting cylinder A, is low, and the side plate 4 on the left side, that is, on the side opposite to the side of raking up mixed rice in the sorting cylinder A, is high.
. One end of the support shaft 21 of the adjustment plate 2 projects outside the case 18, and a locking body 22 that also serves as a lever is fixed to this projecting end. A concave-convex engaging portion 23 formed in an arc shape is fixed to the concave-convex engaging portion 2 .

During work, when paddy is supplied to the supply popper 15, the mixed rice deculled in the huller is removed by the wind flowing toward the suction port 10 of the suction/discharge unit 9, which removes the chaff from the mixed rice conveyor. 6, this mixed rice is supplied from the mixed rice conveyor 6 to the supply side (c) in the sorting cylinder A via the mixed rice thrower 13 and the tank 25. The mixed rice that has entered the sorting cylinder A in this way, the sorting cylinder A
While repeating the flow of being scraped up to the height determined by the rotation to the left of the arrow (E) and then falling to the bottom, the discharge side (Ni) at the other end of the sorting cylinder A is shown by the arrow (G) in ). During this flow, the brown rice in the mixed rice is fitted into the recess 1 on the inner surface of the sorting cylinder A and is lifted up to a higher level than the paddy, and then falls from the recess 1 as shown by the arrow in Figure 3. Rather than that, I entered the brown rice receiving channel B. The brown rice that has entered the brown rice receiving trough B in this way is sent to the exit side as shown by the arrow (J) inside the brown rice receiving trough B by the spiral conveyor C, and passes through the falling trough 28 and grain flow plate 29. The brown rice then reaches the brown rice conveyor 8, from which it is taken out of the machine by the brown rice thrower 14. On the other hand, the mixed rice in the sorting cylinder A is sorted so that the brown rice therein enters the brown rice receiving trough B as described above, and as it is transferred toward the discharge side (d), the proportion of paddy increases. As the amount of paddy increases, it falls from the discharge side (d) to the paddy container 7 via the gutter 27, is sent to the supply hopper 15 by the paddy thrower 17, and the cycle of deculling is performed again is repeated. Then, the height at which the sorting cylinder A falls after being lifted up while being fitted into the recess 1 due to the rotation of the sorting cylinder A,
Depending on the grain type, moisture content, supply amount, etc., the height will be higher or lower, so if the height when lifting and falling brown rice becomes higher, adjust the adjustment plate 2 by rotating it upward. However, if the height when lifting and falling brown rice becomes low, brown rice can be selectively introduced into brown rice receiving channel B by adjusting the rotation of adjustment plate 2. At this time, the left side plate 4 of the brown rice receiving trough B, that is, the side plate 4 on the side opposite to the sowing side of the mixed rice in the sorting cylinder A, is not displaced. 4.
