Description

[Detailed description of the invention] The present invention relates to a rice husking sorter.

That is, by arranging both the primary and secondary rotary sorting cylinders in parallel, mixed rice can be successfully sorted sequentially from the primary to the secondary, and in particular, the height of the machine body can be reduced. In addition, the grain lifting height of the related structure can be efficiently lowered, the power transmission can be simplified, and the overall structure can be simplified and can be suitably implemented.

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

14 are brought into contact with each other.

In addition, receiving troughs B, b for receiving brown rice are installed inside the two rotary sorting cylinders A, a, and both receiving troughs B,
Both receiving troughs B have spiral conveyors 15 and 16 mounted on the inner lower part of b, and a gate valve 17 whose tip approaches the upper part of the inner circumferential surface of the cylinder is installed at one side end of b.
18 in a row, and attach the support shaft 1 at the base.
9 and 20 so that the rotation can be adjusted.

The hulling machine C is located inside the lower part of the case 11.
A conveyor 4a integrated with the No. 1 conveyor 4 is installed, and the terminal end of the conveyor 4a is connected to the mixed rice thrower 21 installed on the rear end side of the case 11, and the end side of the conveyor 4a is connected to the mixed rice thrower 21 installed on the rear end side of the case 11. Installed tank 2
The upper end side of the mixed rice thrower 21 is connected to 2,
A lower port 23 installed vertically below the tank 22 is visible inward at one end of the primary rotary sorting cylinder A on the supply side A, and a gutter installed at the outer lower part of the other end of the rotary sorting cylinder A on the discharge side B The lower part of the paddy thrower 24 is connected to the paddy thrower 25, and the upper end of the paddy thrower 25 is connected to the supply hopper 10.

An intermediate thrower 26 coaxial with the spiral conveyor 15 is installed at the terminal end of the receiving gutter B, which is the discharge side B, and a lower opening 28 below the hopper 27 communicating with the jumping side of the intermediate thrower 26 is connected to the secondary One end of the rotary sorting cylinder a, on the supply side, looks inward, and the other end of the rotary sorting cylinder a, on the discharge side, extends vertically to the outer and lower side, so that the lower opening of the gutter 48 faces the terminal end of the conveyor 4a. A receiving gutter b installed on the drain side and serving as the discharge side D
A brown rice thrower 29 coaxial with the spiral conveyor 16 is connected in communication with the terminal end of the brown rice thrower 29, and the brown rice is taken out from the brown rice thrower 29 to the outside.

In addition, the shaft 3 of the derolling machine 9 in the huller C
The shaft 31 of the No. 01 conveyor 4 and the shaft 3 of both spiral conveyors 15 and 16 in the rotary grain sorter D
2, 33, both machines C and D are connected with the shafts 34 of both drive wheels 12 in the same direction and parallel to each other, and a belt 37 is routed from the pulley 35 of the motor M to the pulley 36 of the shaft 30, and the paddy thrower Pulley 39 on the drive shaft 38 of 25, pulley 4 of the shaft 30
0, pulley 41 of shaft 31 and No. 2 conveyor 5
Wrap the belt 42 around the pulley (not shown),
At the rear, the pulley 43 of the shaft 31 and the shaft 34
A belt 47 is wound around the pulley 44 of the shaft 32, the pulley 45 of the shaft 32, and the pulley 46 of the shaft 33.

Therefore, each part of the huller C can be driven by the motor M via the belts 37 and 42, and
Each part of the rotary grain sorter D can be driven from the shaft 31 of the No. 1 conveyor 4 via the belt 47.

During operation, when paddy is supplied from the outside to the supply hopper 10, the unrolled rice is screened in the wind sorting section 2, and the mixed rice is conveyed from the No. 1 conveyor 4 through the conveyor 4a. The mixed rice is thrown up into the tank 22 by the thrower 21 and fed into the supply side A of the primary rotary sorting cylinder A through the lower port 23.

The rotary sorting cylinder A rotates in the direction of the arrow H, and the brown rice in the mixed rice that engages with the recess 1 is lifted as it rotates, passing between it and the tip of the gate valve 17, and jumping upward. As shown by the arrow , the paddy in the mixed rice falls into the receiving trough B, and even though it is lifted, it is blocked by the gate valve 17 and flows downward, and is transported in the direction of the arrow , and is then directly transferred to the discharge side. As it falls from B to 24, the paddy thrower 25
It is thrown up into the supply hopper 10 and released again.

The brown rice, etc. that have fallen into the receiving trough B are conveyed in the direction of the arrow H by the spiral conveyor 15, and then jumped up by the intermediate thrower 26 to the hopper 27, and then passed through the lower opening 28 to the supply side of the secondary rotary sorting cylinder a. There, it is sorted in the same manner as described above by the rotating barrel a as shown by the arrow, and then sent to the receiving trough b.
The brown rice that falls into the machine is conveyed by the spiral conveyor 16 in the direction of arrow R, and is jumped out of the machine by the brown rice thrower 29. The paddy that is conveyed in the direction of arrow N in the secondary rotary sorting cylinder a is passed from the discharge side to the gutter. 48 and falls onto the conveyor 4a, whereupon it is jumped up into the tank 22 by the mixed rice thrower 21 to be sorted again.

In this way, the present invention provides both primary and secondary rotary sorting, each of which is equipped with a receiving gutter for receiving and conveying brown rice, and has a large number of recesses large enough to fit brown rice on its inner peripheral surface. Since the barrels are arranged close to each other in the horizontal direction and are integrally arranged on the side of the huller, the mixed rice can be sorted in sequence from the first to the second by the dual rotary sorting barrels. The height of the machine body can be lowered by arranging both bodies side by side in the horizontal direction, and the height of the related structure such as the thrower can also be lowered to allow efficient grain transport. The transmission structure is also simplified, and the structure as a whole can be simplified, which has the advantage of being suitable for implementation.
