Description

[Detailed Description of the Invention] That is, brown rice can be reliably and well sorted from the mixed rice after hulling, and it can be sorted with great accuracy by circulating it, and the single rotating sorting cylinder and its internal configuration have good performance. Moreover, it can be constructed in a small size and can be suitably implemented.

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

Figure 1 shows a side view of the entire hull sorting machine. ), and the suction port 01 of the suction dust extractor (9) on one end side is installed so as to communicate with the upper side of each conveyor through each suction port tllll j+21, and both conveyors (
6) At one end of (3), a mixed rice thrower (l3) and a brown rice thrower (l4) are installed in series, and a j wind selection box (C
) is equipped with a husking section (D) equipped with a supply hopper 1151 and a dehusking roll (16), and a paddy thrower (17L) connected to the paddy conveyor (7) that supplies the upper part of the paddy Hopper-tl51K is installed so that it communicates with the slider.

Above the other end of the wind sorting box (0) is a rotary grain sorting device (E
), but the device fE) is supported by two rotary wheels: l91 1191 at the lower sides of both ends of a rotary sorting cylinder (A) with open ends installed inside the case (l81), and at the same time the upper The presser ring (2))) is brought into contact with the rotary sorting cylinder (A+ one end feeding rule 1a), and brown rice is placed on the inner circumferential surface of the range slightly longer than the middle in the axial direction. In addition to forming four parts (]) with the size of
It is constructed by forming a large number of recesses (2) each having a smaller dog shape, but as shown in Fig. 5, it is constructed by forming the recesses (2) gradually from the fourth part (1) side to the large recess part (2). You can also do that.

There is still a V-shaped receiving gutter (
Both ends of B) are connected in the case (18), and the receiving gutter (B)
A spiral conveyor (3) is mounted on one side corresponding to the recess (1), and a spiral conveyor (4) is mounted on the other side 1011 corresponding to the large recess (2) on the rotating shaft 4H mounted inside the shaft in opposite directions. Wrap it so that it is facing the right direction, and place it on both conveyors (3).
(Inside the receiving trough (B) between 41 and 41, a partition root is installed, and the part of the gate valve (b) that extends from one side of the receiving trough (B) to the other is connected to the spiral conveyor (3). ) is formed into a long plate part whose tip approaches the inner circumferential surface of the cylinder, and the spiral conveyor (4)
The side part of the gate valve fb) is formed into a short plate part] 24) whose tip is away from the inner circumferential surface of the body and shorter than the long plate part 123). The partition plate (b) is installed so that it can be rotated and adjusted by operating the main cause of the adjustment (actual cause of the adjustment), but the part of the gate valve fb) is integrated as a lateral extension of the receiving gutter (B). It can also be formed into

The tank installed on one end of the case (181)
The upper end of the mixed rice thrower (13) is communicated with the upper end of the mixed rice thrower (13), and the lower outlet of the tank guard is connected to the rotary sorting cylinder (A).
) is installed so as to extend inward on the supply side (a) of the rotary sorting cylinder (A), and installed so that the gutter at the bottom of the discharge side (b) end of the rotary sorting cylinder (A) is communicated with the top of the paddy conveyor (7). The lower part of the communication gutter sluice hanging down from the terminal end side of the spiral conveyor (3) is connected to the grain board e11 above the brown rice conveyor (8).
The spiral conveyor (4) is installed at an angle so as to connect to the
A communication gutter (32) is installed so that the lower part thereof extends above the mixed rice conveyor (6).

Therefore, when each rotating wheel 1191; 191 is rotationally driven, the rotating sorting cylinder (A) rotates as shown by the arrow (C) due to frictional contact.

During operation, when paddy is supplied to the supply hopper 115), the mixed rice that has been desexed and wind-selected in the hulling section (D) falls onto the mixed rice conveyor (6) and is transferred to the mixed rice thrower. -113) was jumped by tank (2),
The rotary sorting cylinder (A) from the lower part of the 111 f28)
The supply side (a) is fed inward.

Therefore, as shown by the arrow (c), the rotary sorting cylinder (
The brown rice is stuck in each recess (1) on the inner circumferential surface of A), and is lifted as the rice is rotated, and the end of the long plate of the gate valve (b) and the inner circumferential surface of the body are The recess (1) passes through the narrow space of the receiving trough (as shown by the arrow).
B) The rice is released into the sluice valve (b), and the paddy does not get caught in the fourth part (1).Even if the bean falls down and is pulled a little, the long plate part of the gate valve (b) - tip and body. It cannot pass through the space between the inner circumferential surface and is partitioned and flows downward. As a result, when the mixed rice with a large proportion of paddy is transported in the direction of the arrow (E), the remaining brown rice is completely engaged by the large concave portion (2), but at the same time, the paddy is also less likely to be engaged, and a part of the paddy is lifted together, causing the tip of the short plate part of the gate valve (b) and the inner circumferential surface of the body to The mixed unhulled rice and paddy will pass through the wide space between the two and fall into the receiving container (B) as shown by the arrow in Fig. 4.

The paddy discharged from the discharge side (B) of the rotary sorting cylinder (A) falls from the gutter onto the paddy conveyor (7) and is transferred to the paddy thrower f+71.
The brown rice that is bounced up from K to the hulling section (D) and circulated, and that falls onto the spiral conveyor (3), is conveyed in the direction of arrow (G) and passes through the connecting gutter and the grain plate (31). The mixed rice that fell onto the brown rice conveyor (8), was taken out by the brown rice thrower f141, and was thrown into the spiral conveyor (4) in the direction of the communication gutter 02 as shown by the arrow. The mixed rice is carried out and falls onto the mixed rice conveyor (6), where it is again jumped up into the mixed rice thrower T+31 tank and re-sorted.

Therefore, brown rice is prevented from remaining in the paddy and being rubbed twice by the hulling section (D).

As described above, the present invention has a large number of recesses large enough to fit brown rice on the inner circumferential surface near one end of the rotary sorting cylinder, and a large recess slightly larger than the recesses on the inner circumferential surface of the other end. A spiral conveyor is constructed in which the feeding direction of the parts corresponding to the concave side and the large concave side are opposite, in the receiving gutter which is formed in large numbers and fixed inside the rotary sorting cylinder. The lateral extension of the single core receiving trough is close to the inner peripheral surface, and the large concave part (IJII) is formed long and short so that the lateral extension of IJII is away from the inner peripheral surface, so that the mixed rice after hulling can be removed. It can sort brown rice reliably and well, as well as circulate it and sort it with high precision. It has a single rotating sorting cylinder, a gutter valve inside it, and a spiral conveyor, so it has good performance and can be constructed in a small size. It has the advantage of being able to prevent so-called double rubbing and can be carried out suitably.
