Description

[Detailed description of the invention] The present invention relates to a receiving trough for a cylindrical sorting rice huller.

Conventionally, cylindrical sorting hullers have a rotating sorting tube with many indentations and a receiving gutter inside, and feed a mixture of paddy and brown rice from one end of the tube while slowly rotating the sorting tube. death,
Flow through the sorting tube in the axial direction. In the middle of the flow, the mixed rice tries to be scooped up as the sorting cylinder rotates, but the brown rice tends to sink, gets stuck in the depression, and is lifted upwards, drawing a large parabola. Fall. On the other hand, paddy can also be scooped up, but since it does not fit into the dent, it falls in a small parabola. A drain is installed at the point where the brown rice falls, so the paddy and brown rice are separated.

By the way, the present invention is aimed at improving the culling rate (mixed polymerization of brown rice and paddy).
We realized that separating brown rice as finished rice from mixed rice with a high culling rate has higher sorting performance than separating brown rice from mixed rice with a low culling rate. The present invention aims to provide a yen-m sorting huller that is commonly used and has high sorting performance.

This will be described below with reference to embodiments shown in the accompanying drawings. Fig. 1 shows a cross section of the entire cylindrical rice sorting/hulling hall A, and the hulling machine Δ has a hulling part C placed on one side of the upper surface of the wind sorting device B, which is a rectangular box, and is placed side by side with this. A rotary sorting machine D@ is installed to make up the entire system.

In the wind sorting device B, a scraped rice screw conveyor 1 consisting of a shaft that doubles as a scraped rice thrower shaft and a brown rice screw conveyor 2 consisting of a shaft that doubles as a brown rice thrower shaft are installed side by side. The rice screw conveyor 1 has a wind-selecting room 3,
The brown rice screw conveyor 2 is installed at the bottom of each finished rice sorting room 4. A suction dust extractor 5 is provided at one end in the longitudinal direction of the wind selection device B, a suction port 6 is provided at the other end, and the wind selection room 3
, the sorting wind is flowing above the finished rice wind sorting room 4 and the Xiaomi wind sorting room 30.

On the machine side, there are a brown rice thrower 7 that communicates with the brown rice screw conveyor 1 and is driven by the conveyor shaft, and a brown rice thrower 8 that communicates with the brown rice screw conveyor 2 and is driven by the conveyor shaft. It is set up.

The hulling section C incorporates a pair of de-weighing rolls 9, and has a hopper 10 installed above them, and the scraped rice screw conveyor 1 is placed below the dehulling rolls 9.

The rotary sorting machine has a primary sorting tube I and a secondary sorting tube ■ placed horizontally in two stages, upper and lower, in a box-like case 12.

The axial direction of these sorters fii'il and n is perpendicular to the axis of the culling roll 9.

These sorting tubes 1. A large number of depressions 13 are formed around the entire inner periphery of II, large enough for brown rice to fit into.The diameter of the depressions 13 is 5 to 6.51 cm, and the depth is 3.
A hemisphere of about 41 cm is appropriate. Both ends of the sorting tubes 1 and 11 are open, and various receiving troughs for receiving brown rice each having a substantially V-shaped cross section are inserted and suspended horizontally therein as will be described later.

That is, as shown in FIG. 2, a secondary sorting tube I is horizontally suspended with a secondary sorting receiving trough 14 and a supply conveyor 15 communicating with the dropped rice thrower 7. In this case, a receiving trough 16 for finished rice and a receiving trough 17 for small rice are suspended horizontally. A gate valve 19 is connected to the end of the receiving side plate 18 of the secondary sorting receiving trough 14, and the supply conveyor 15 is provided with an opening 20 that opens below the partition 19 over approximately the entire length. A gate valve 22 is also connected to the receiving side plate 21 of the opening 20 to adjust the degree of opening of the opening 20.

The finished rice receiving gutter 15 and the small rice receiving gutter 17 are installed side by side, but the opening 23 of the finished rice receiving gutter 16 is closer to the small rice receiving gutter 1.
It opens at a lower position than the opening 24 of No. 7.

A gate valve 26 is connected to the receiving side plate 25 of the finished rice receiving gutter 16, and a gate valve 28 is connected to the receiving side plate 27 of the small rice receiving gutter 17 to adjust the opening degree of each opening 23,24. .

The starting end of the supply conveyor 15 communicates with a supply tank 29 facing the upper end of the dropped rice thrower 7, and its terminal end facing the inner surface of the primary sorting tube 2. The terminal end of the secondary sorting holder wfJ14 is connected to the inner surface of the rear body of the secondary sorting tube ■ (opposite the hulling section C, right end in Figure 1) through a chute 31, and is connected to the receiving trough for finished rice. The terminal end of the small rice receiving trough 17 communicates with the finished rice sorting chamber 4 in the wind sorting device B, and the terminal end of the small rice receiving trough 17 communicates with the front of the machine.

This embodiment has the above-mentioned configuration, so to explain its working condition, when paddy is manually fed into the hopper 10 from a paddy bag, it is deweighed by the huller C, and the paddy and brown rice are mixed. The rice, suroshimai, is wind-selected on the way down in the wind sorting section B to remove the rice husks and second grains, and falls onto the suroshimai screw conveyor 1, where it is thrown up by the surobachi rice thrower 7. and flows into the supply tank 29. It flows down from the supply tank 29 to the supply conveyor 15, and is thereby supplied to the rear side of the machine in the primary sorting vJI. Since the sorting tube I is rotating, the scraped rice that has been deposited by the supply is going to be pumped up by the rotation of the sorting tube ■, but the brown rice has sunk and is stuck in the depression 13, and has not reached the top. It is lifted up and released, and falls into the secondary sorting receiving trough 14. On the other hand, a part of the paddy mixed with brown rice jumps into the opening 20 of the supply conveyor 15, mixes with new fallen rice, and is again supplied to the inner surface of the sorting cylinder (2) and circulated. Opening 20 of supply conveyor 15
Are the paddy that did not jump into the sorting process? From the end of i1, it is transferred to the hopper 10 and subjected to the culling action again.

The brown rice with some paddy mixed in is supplied from the end of the secondary sorting receiving trough 14 through the chute 31 into the secondary sorting tube ■.
Under the same action as the next sorting tube ■, only normal brown rice is pumped into the finished rice receiving trough 16. Moreover, since the parabola of the small rice is drawn large, it is pumped into the small rice receiving trough 17. The small rice receiving trough 17 communicates with the front of the machine, and the small rice is carried out of the machine from here. The brown rice mixed with a small amount of paddy that cannot be pumped into either the finishing trough 16 or the small rice receiving trough 17 flows into the draft sorting chamber 3, where it is mixed with new grain, and is sent to the next sorting tube I again. Supplied.

FIG. 3 shows that in the embodiment shown in FIG. 1 shown in FIG. 2, the small rice receiving gutter 17 is replaced with a finished rice receiving gutter 16', the opening 24 is made larger, and the finished rice receiving gutter 16' is used instead of the small rice receiving gutter 17. Instead, a new lower trunk circulation receiving trough 32 is provided. Therefore, the brown rice slightly mixed with paddy is pumped up by this lower body circulation receiving trough 23, is supplied to the vicinity of the opening of the chute 31, and is circulated inside the secondary sorting cylinder (2). For this reason, the brown rice whose paddy has been reduced is not mixed into the newly removed rice, so that the separation performance of the whole sorting machine is improved.

FIG. 4 shows that in the second embodiment shown in FIG. 3, a rough sorting receiving trough 33 is provided in place of the supply conveyor 15, and its terminal end is communicated with the inner surface of the secondary sorting tube H through a chute 31'. There is. Further, the secondary sorting receiver Jul 14 is made into a finished rice receiving channel 16'', and its terminal end is communicated with the finished rice receiving channel 16 of the secondary sorting tube (2) via the chute 34. Since there is no supply conveyor 15 in the tube I, the dropped rice thrower 7, not shown in FIG. 1, is extended to feed rice into the primary sorting tube I from the rear of the machine.

In summary, the present invention provides a plurality of stages of approximately water-shaped sorting tubes arranged side by side, each of these sorting tubes having a receiving gutter, and at least one of these sorting tubes having a channel inside the sorting tube. Since this is a receiving trough for a cylindrical sorting rice huller with an additional receiving trough that circulates only rice, it has the following effects.

■Since multiple stages of sorting cylinders are installed in parallel, it is possible to improve the sorting performance by sequentially moving from rough sorting to fine sorting, and also to circulate the inside of the sorting cylinder using a receiving gutter that has a certain degree of sorting performance. Therefore, the amount of flow back to the huller or other sorting tube can be reduced, the deculling rate can be gradually increased, and the sorting performance can be improved.

(2) Since the receiving gutter is used as a means for circulating only within the sorting cylinder, it can also be used for other functions, such as a supply conveyor, and the number of parts can be reduced.
