(Prior art) Conventionally, two pot-hole horizontal sorting tubes with numerous pot holes formed on the inner circumferential surface are arranged in two rows, upper and lower, and the grains scooped out by the pot holes are stored in the pot-hole horizontal sorting tubes. A receiving gutter is installed horizontally to receive the grain, and a transfer conveyor is installed in the receiving gutter, and the grain received by the receiving gutter of one pot-hole horizontal sorting tube is supplied to the other pot-hole horizontal sorting tube. A device formed in series so as to be possible is known from Japanese Utility Model Application Publication No. 56-14743.

(Problems to be Solved by the Invention) The above-mentioned known method has a pot-hole horizontal type sorting tube with two upper and lower sides.
Because the brown rice that fits into the pot holes is scooped up and sorted, it is possible to separate the mixed rice of unhulled rice and brown rice, but it is not possible to remove the lean rice (waste rice) from the brown rice. Nakatsuta.

(Means for Solving the Problem) Therefore, the present invention provides at least two pot hole horizontal tube type sorting tubes 11 and 17 in which countless pot holes 12 are formed on the inner peripheral surface, and Inside the cylindrical sorting tubes 11 and 17, there is a receiving trough 1 for receiving the grains scooped in the pot hole 12.
4 and 18 are installed horizontally, and a transfer conveyor 15 is installed in the receiving troughs 14 and 18, and the grains received by the receiving trough 14 of one pot-hole horizontal tube type sorting tube 11 are transferred to the other pot-hole horizontal tube. They are formed in series so that they can be fed into the grain sorting tubes 17, and one or two sieve type grain sorting tubes 19 are arranged in parallel in the vicinity thereof, and the terminal end of the horizontal grain sorting tubes 17 is connected to the sieve. This is a mixed rice processing device that is connected to the starting end of a type grain sorting cylinder 19 to form a serial sorting path.

(Example) An example of the present invention will be described with reference to the drawings.
1 is a rice hulling device, which has a supply hopper 2 on the upper part, and a pair of rubber rolls 3, 3 are mounted on the lower part of the supply hopper 2. 4 is a wind sorting room, where lightweight rice husks are blown away and sorted. An elevator 5 is attached to the side in order to fry the mixed rice of unhusked rice and brown rice from which the chaff has been removed. 6 is its discharge gutter, and 7 is a storage tank. A receiving port 10 for the feed conveyor 9 is provided below the discharge port 8 at the lower end of the storage tank 7 .
The feed conveyor 9 moves the fried grains away from the hulling device 1, and supplies the grains to the supply port of one of the pot-hole horizontal tube type sorting tubes 11 as shown in FIG. A pot hole 12 for scooping up the brown rice distributed in the lower layer is formed entirely on the inner surface of the pot-hole horizontal sorting tube 11 (Fig. 3), and the brown rice 13 is scooped up and dropped at the upper position. A receiving gutter 14 for receiving the water is installed horizontally within the pot-hole horizontal cylinder type sorting tube 11. A transfer conveyor 15 is provided within the receiving trough 14, and a transfer device 16 such as a swallow is attached to the end thereof. Next to one pot hole horizontal tube type sorting tube 11, the other pot hole horizontal tube type sorting tube 17 is arranged in parallel, and the grain discharged from the transfer device 16 is transferred to the other pot hole horizontal tube type sorting tube 17. It is supplied to the supply end of the cylinder 17. The structure of one pot-hole horizontal tube type sorting tube 11 and the other pot-hole horizontal tube type sorting tube 17 are the same, and a receiving gutter 18 is similarly installed inside. 15 are installed horizontally. A sieve-type grain sorting tube 1 is located below the two side-by-side jar-hole horizontal sorting tubes 11 and 17.
9 is provided. The sieve-type grain sorting tube 19 separates waste rice from the brown rice 13, and is formed of a punched perforated plate.

The pot-hole horizontal type sorting tubes 11, 17 and the sieve type grain sorting tubes 19 as described above are formed in various combinations as shown in FIG. A sieve-type grain sorting tube 19 is arranged at the lower center of the horizontal tube-type sorting tubes 11 and 17, but in the case of FIG. It is arranged as follows. Each arrangement of two pot-hole horizontal type sorting tubes 11 and 17 and a sieve type grain sorting tube 1
There are other placements of 9, and in some cases,
As shown in FIGS. 4 and 4, there may be four sorting tubes.

(effect) Next, we will discuss the effect.

The unhusked rice loaded in the supply hopper 2 is hulled by a pair of rubber rolls 3, 3, and falls into the wind selection chamber 4, where the lightweight rice husks are blown away and removed, and the rice is separated into unhulled rice. The mixed brown rice is transported horizontally by the screw conveyor 20 and flows into the lower end of the elevator 5, rises inside the elevator 5, and flows into the storage tank 7 through the discharge gutter 6. The mixed rice that has fallen from the discharge port 8 of the storage tank 7 is sent from the receiving port 10 to the conveyor 9.
and flows into one pot-hole horizontal-tube type sorting tube 11 as shown in FIG. Pot hole horizontal tube type sorting tube 1
Inside 1, the inner surface is formed with a pot hole 12 that scoops up brown rice 13, and as the pot-hole horizontal sorting tube 11 rotates, brown rice grains with heavy specific gravity are stirred and sink to the lower layer. Since unhulled rice with a small specific gravity floats to the upper layer, the brown rice 13 that fits into the pot hole 12 is scooped up one after another and falls into the receiving trough 14.

In this case, during the scooping operation using the pot hole 12 of the pot-hole horizontal tube type sorting tube 11, some of the unhulled rice is also scooped out, but only the unhulled rice remains in the pot-hole horizontal tube type sorting tube 11. This is received by the inclined plate 21 at the bottom thereof, flows further, and is returned to the supply hopper 2 for reprocessing.

On the other hand, brown rice including some unhulled rice in the receiving trough 14 is sent by the transfer conveyor 15 and supplied to the other pot-hole horizontal tube-type sorting tube 17, where it is similarly sorted. It is sorted and taken out as finished rice. This finished rice contains thin rice scraps, but is supplied to the lower sieve-type grain sorting cylinder 19 through the drain 22, and the scrap rice is removed by size selection. The removed waste rice is collected in a gutter 22 and then collected in a storage box 23.

(Effects) As mentioned above, conventionally, the pot hole horizontal tube type sorting tubes with countless pot holes formed on the inner circumferential surface are arranged in two rows, upper and lower, and the pot hole horizontal tube type sorting tubes have the holes for scooping. A receiving gutter is installed horizontally to receive the grains, and a transfer conveyor is installed in the receiving gutter. The one formed in series so that it could be supplied into the cylinder was developed in 1982.
It was publicly known from Publication No. 141743. However, the above-mentioned known method has two vertical and vertical sorting tubes arranged side by side,
Since the brown rice that fits into the pot hole is scooped up and sorted, even if it is possible to separate the mixed rice of unhulled rice and brown rice,
It was not possible to remove lean rice (waste rice) from brown rice.

However, the present invention has numerous pot holes 12 on the inner peripheral surface.
At least two pot-hole horizontal tube type sorting tubes 11, 17 are arranged in parallel, and the pot-hole horizontal tube type sorting tubes 11, 17 are arranged in parallel.
Receiving troughs 14 and 18 for receiving the grain scooped in the pot hole 12 are installed horizontally therein, and a transfer conveyor 15 is installed in the receiving troughs 14 and 18. They are formed in series so that the grains received by the receiving trough 14 can be fed into the other pot hole horizontal tube type sorting tube 17, and one or two sieve type grain sorting tubes 19 are arranged in parallel in the vicinity thereof, Since this is a mixed rice processing device in which the terminal end of the pot-hole horizontal sorting tube 17 is connected to the starting end of the sieve-type grain sorting tube 19 to form a serial sorting path, it is possible to use a mixed rice processing device as a single integrated device. After separating the mixed rice into paddy rice and brown rice, waste rice in the brown rice can also be removed, and because of the rotating structure, the device can be made quiet.
