Description

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

Conventionally, a cylindrical sorting huller (a rotating sorting cylinder equipped with a number of scissors has a receiving gutter inside it, and while the sorting cylinder is slowly rotating, a mixture of paddy and brown rice is removed from one end of the cylinder). supply,
Flow through the sorting tube in the axial direction. During the flow, the mixed rice tries to be lifted up by the rotation of the sorting cylinder, but the brown rice sinks and becomes a sifter, gets stuck in the clump, and is lifted upwards. Then, it falls in a large parabola. On the other hand, the paddy can also be picked 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 focused on the fact 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, and applied this to a cylindrical sorting huller. The present invention aims to provide a cylindrical sorting huller with 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 sorting huller A, and the huller tMA has a huller C placed on one side of the upper surface of the wind sorter B, which is a rectangular box, and is rotated side by side with the huller C. A sorting machine is installed to form the whole structure.

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 suromi rice screw conveyor 1 has a surimi style sorting 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 unruly rolls 9, and has a hopper 10 installed above them, and the scraped rice screw conveyor 1 is placed below the unruly rolls 9.

The rotary sorting 1fiD has two upper and lower stages in a box-like case 12, and a primary sorting tube "lI?ji" and a secondary sorting tube "■" are suspended horizontally in a substantially horizontal manner.The axial direction of these sorting tubes I and II is It is perpendicular to the axis of the quartz roll 9.

A large number of hemispherical depressions 13 large enough to fit brown rice are formed over the entire inner periphery of these sorting tubes I and U. The diameter of the depression 13 is 5 to 6.51, and the depth is 3 to 4.
A hemisphere of about fi is appropriate. Sorting tube 1. Both ends of n 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 pipe 14 and a supply conveyor 15 communicating with the dropped rice thrower 7 are horizontally mounted on the secondary sorting tube I, and the secondary sorting tube H is 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 is opened 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 receiving trough 14 for secondary sorting communicates with the inner surface of the rear body of the secondary sorting cylinder (the right end in Fig. 1 on the opposite side of the hulling section C) through a chute 31, and is connected to the inner surface of the secondary sorting tube ■ at the rear of the machine body (the right end in Fig. 1 on the opposite side of the hulling section C). The end of the gutter 16 communicates with the finished rice sorting chamber 4 in the wind sorting device B, and the end of the small rice receiving gutter 17 communicates with the front of the machine.

Since this embodiment has the above-mentioned configuration, the working condition will be described as follows: When paddy is manually fed from the paddy bag to the huller 10, the paddy is deweighed by the huller C, and the paddy is Surirakumai, which is a mixture of brown rice, is wind-selected on the way down in wind sorting section B to remove the rice husks and second grains, and then falls onto Suriroshimai screw conveyor 1, where it is passed through Surirachimai thrower 7. and flows into the supply tank 29. It flows down from the supply tank 29 to the supply conveyor 15, whereby the primary sorting vJl
It is supplied to the rear of the aircraft inside. Since the sorting tube I is rotating, the scraped rice that has been fed and piled up is quickly pumped up by the rotation of the sorting tube I, but the brown rice has sunk and is stuck in the recess 13, and is pushed upwards. It is lifted up and released until it falls into the receiving gutter 14 for secondary sorting. 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 tube I, where it is circulated. Opening 2 of supply conveyor 15
The paddy that did not jump into the 0 column is transferred to the homper 10 from the end of the sorting tube 1, and is subjected to the misbehaving action again and is fed into the secondary sorting tube ■ through the chute 31 from the end of the secondary sorting gutter 4. The unpolished rice with some paddy mixed in is subjected to the same action as the secondary sorting pipe, and only normal unpolished rice is pumped into the finished rice receiving trough 16. Also, Xiaomi has a large parabola.
Since the rice is drained, it can be 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. Finishing gutter 16 and small rice gutter 1
The brown rice mixed with a small amount of paddy that cannot be pumped into any of the above 7 flows into the shorai wind selection room 3 and is mixed with new shorai.
Again - supplied to the person selection section.

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 with some paddy mixed in is pumped up by this lower body circulation receiving trough 23, is supplied near the opening tilt of the chute 31, and is circulated inside the secondary sorting tube (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 2 through a chute 31'. There is. In addition, the receiving trough 14 for secondary sorting is replaced by the receiving trough 16 for finished rice.
', and its terminal end communicates with the finished rice receiving trough 16 of the secondary sorting cylinder (2) via a chute 34. Therefore, since there is no supply conveyor 15 in the secondary sorting cylinder I, the dropped rice thrower 7 shown in FIG. 1 is extended to supply rice into the primary sorting wII from the rear of the machine.

In summary, the present invention provides a plurality of stages of substantially horizontal sorting tubes arranged side by side, each of these sorting tubes having a receiving gutter, and at least one of these sorting tubes having only one inside the sorting tube. Since this is a receiving trough for a cylindrical sorting rice huller equipped with a receiving trough that circulates water, 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 hulling section or other sorting tube can be reduced, the rate of waste grain 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.
