Description

[Detailed description of the invention] The present invention relates to a rice huller sorting device.

That is, the mixed rice obtained by removing air from the huller is sorted into brown rice and paddy using a rotating sorting barrel, and the small rice is removed from the sorted brown rice so that the brown rice can be carefully selected. To provide a system that can perform sieving and sorting of brown rice reliably and satisfactorily at once, can be constructed in a compact size without taking up space as a whole, and can be carried out suitably.

Next, the embodiment shown in the drawings will be described.

Figure 1 shows a side view of the entire huller sorting device.
Inside the long sorting box E, a suction dust remover 3, a mixed rice conveyor 5, a brown rice conveyor 6, etc. are arranged, and above each conveyor 5, 6 there are air passages 4, 7 communicating with the suction dust remover 3. Extend and install as desired,
Above one side of the sorting box E, a huller D having both derolling machines 9 below the hopper 8 is integrated, and at the ends of the mixed rice conveyor 5 and brown rice conveyor 6, a mixed rice thrower 10 and brown rice are installed. It is constructed by arranging throwers 11 in series.

Inside the case 12 which is integrally installed above the other side of the sorting box E, cylindrical rotating sorting cylinders A, a with open ends are installed parallel to each other. A large number of recesses 1 are formed on the inner circumferential surface of the box, and the rotating shafts 13 and 14 mounted on the case 12 have two rotary sorting cylinders A,
The other end side of a is mounted via arms 15 and 16,
Supporting rods 17, 17 are connected to both sides of the lower part of one end side of both rotary sorting cylinders A, a, and both rotary sorting cylinders A,
In a, there is a receiving gutter B whose one end is connected to the case 12,
b, respectively, and spiral conveyors 18, 19 wound around rotating shafts 13, 14 are installed in both receiving troughs B, b.
are respectively constructed, and gate valves 20 and 21, which can change the inclination by approaching the side portions of the inner circumferential surface of the cylinder, are arranged in series on the sides of both receiving troughs B and b, respectively.

Further, a tank 22 is installed above one end of the case 12 and communicates with the upper part of the mixed rice thrower 10.
The lower opening 23 of the tank 22 is connected to the upper rotating sorting cylinder A.
A gutter 25 extending toward the hopper 8 and communicating with the terminal end of the receiving gutter B is a gutter 24 that extends inward on one end side and downwardly on the other end side of the rotary sorting cylinder A.
A gutter 27 with a lower opening 26 extending inwardly toward one end of the lower sorting cylinder a and downwardly extending toward the other end of the rotary sorting cylinder a is extended above the mixed rice conveyor 5. Configure.

A long rice sorting barrel C is installed at a slight inclination inside the sorting box E below the lower rotary sorting barrel a. The rotating shaft 28 that horizontally suspends the rice sorting barrel C is mounted on metals 29 and 30, and the outer transmission shaft 31 and the rotating shaft 28 are connected via a universal joint 32. A lower opening 34 of a gutter 33 hanging down from the terminal end of the receiving gutter b is provided at the inclined upper end of the body C.
The lower inclined end of the rice sorting cylinder C is seen above the brown rice conveyor 6, and both gutters 35, 3 are installed below the rice sorting cylinder C in a direction perpendicular to the rice sorting cylinder C.
5 are arranged in parallel, and spiral conveyors 36, 36 are installed in both gutters 35, 35, respectively, and sorting boxes E are installed.
Small rice outlet ports 37, 37 are provided below the ends of both gutters 35, 35 extending outwardly.

FIG. 5 shows another embodiment, which has almost the same structure as the previous embodiment as indicated by the same reference numerals, but an air passage 38 connected to the suction dust ejector 3 is connected from the bottom of the sorting box E to the other end. and the terminal end 3 of the air passage 38.
9 is installed so as to communicate with the sloping upper end of the rice sorting barrel C, and the wind sucked through the suction port 40 formed in the sorting box E passes above the brown rice conveyor 6, and the inside of the rice sorting barrel C. It is installed and configured so that it flows through the air passage 38.

During work, when the mixed rice that has been removed and wind-selected by the huller D falls onto the mixed rice conveyor 5, it is thrown up into the tank 22 by the mixed rice thrower 10, and the mixed rice is fed from the lower port 23. The rice is circulated by the rotating sorting cylinder A as shown by arrow A, and the brown rice that fits into the recess 1 is lifted upwards and falls into the receiving gutter B from above the gate valve 20, and the brown rice that fits into the recess 1 is lifted into the receiving gutter B from above the gate valve 20. The paddy that is circulated without being inserted is separated by the gate valve 20 and remains in the rotary sorting cylinder A, and the paddy is transferred as it is and is sent from the end through the gutter 24 to the hopper 8 and sent to the huller D again. It is removed by.

In this case, since the mixed rice is roughly sorted in the rotary sorting cylinder A, the brown rice in the receiving gutter B is conveyed as it is by the spiral conveyor 18 with a small amount of paddy mixed in, and is fed through the gutter 25 to the rotary sorting cylinder a below. The brown rice that has been sorted in the same manner as above falls into the receiving gutter b,
The paddy with remaining brown rice in the rotary sorting cylinder a is conveyed as it is and falls into the mixed rice conveyor 5 through the gutter 27, and is again thrown up by the mixed rice thrower 10 and re-sorted.

The brown rice in the receiving gutter b is conveyed by the spiral conveyor 19, passes through the gutter 33, and is supplied from the lower opening 34 to the inclined upper end of the rice sorting barrel C, while the brown rice flows down inside the rotating rice sorting barrel C. The small rice in the brown rice leaks from the sorting hole 2 and falls into the gutter 35, 35, and is conveyed by the spiral conveyor 36, 36 and taken out from the small rice outlet 37, 37, and is sent to the rice sorting barrel. The brown rice in C falls into the brown rice conveyor 6 from the lower side of the slope and is taken out of the machine by the brown rice thrower 11.

Note that when configured as shown in FIG.
The suction air flowing through the brown rice conveyor 6 flows inside the rice sorting cylinder C from above the brown rice conveyor 6, so that a wind sorting effect can be performed.

In this way, the present invention provides at least two rotary sorting cylinders A, a which are horizontally suspended and have a large number of recesses 1 into which brown rice can fit, and the rotary sorting cylinders A,
Receiving troughs B and b are installed inside a to receive the rice lifted by the recess 1, and the mixed rice of brown rice and paddy obtained by de-air sorting from the huller D is transferred to one rotary sorting cylinder A. The coarsely selected brown rice is roughly selected and received in the receiving trough B in this rotary sorting cylinder A, and is then supplied to the other rotary sorting cylinder A for fine selection. The structure is such that small rice mixed in unpolished rice is removed by supplying it into a horizontal rice sorting cylinder C with holes 2 formed therein, and these hulling machines D
Since the rotary sorting cylinders A, a and rice sorting cylinder C are integrated, the mixed rice obtained by de-air sorting from the huller can be roughly sorted and finely sorted by the rotary sorting cylinders A, a. This sorted brown rice is efficiently and completely sorted into brown rice and paddy, and the mixed small rice is removed from the sorted brown rice by the rice sorting cylinder C, so that husking and sorting of brown rice can be carried out reliably and well at once. ,
Moreover, since the huller D, the rotary sorting cylinders A, a, and the rice sorting cylinder C are integrated, they can be constructed in a compact size without taking up space as a whole, and have the advantage of being suitable for implementation. .
