Description

[Detailed description of the invention] The present invention is directed to (7) a rice hulling sorting device.

In other words, it is configured so that the mixed rice after hulling can be sorted sequentially by the upper and lower rotating sorting cylinders.It has good performance and can be sorted reliably, and when the upper sorting cylinder can completely sort the rice, the lower One of the best ways to avoid random sorting with a sorting barrel! , 1-1 transmission, efficient sorting, and suitable implementation.

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

Figure 1 shows a side view of the entire rice hulling sorting device. Inside the long wind sorting box (0), from one end side, there is a suction dust remover (3), a No. 2 conveyor (4), a mixed rice conveyor (5), Brown rice conveyor (6
), and the suction port (9)'K of the suction dust extractor (3) is connected through the suction port (7) (s) [7, at one end of both conveyors (5) (6). is mixed rice,
Thrower Q (] and brown rice thrower 11) are installed in communication with each other, and a hopper 11 is installed above one end of wind selection box fc).
At the bottom of 21, there are both stripping rolls (13) (the stripping part of 131 (
141 is installed and constituted by a hulling section (D).

A sorting device (E) is installed above the other end of the wind sorting box (C), and the sorting device (g) has both ends open and an inner Rotary sorting cylinders (A) (a) each having a large number of recesses (1) large enough to fit brown rice are installed on the circumferential surface, and upper sorting cylinders (A) are constructed.

The rotating shaft tlBl and the rotating shaft its 11% are equipped with a gear box (3 [1 (1111 to

On the supply sides (a) and (c) of both sorting cylinders (A) (a), a downstream gutter 0 communicating with the terminal end side of the receiving gutter (B) is installed vertically along the case (15), The downstream gutter (3
The lower part of the gutter 2 is branched and one gutter lower part 63) is connected to the receiving gutter (b

The shaft (35) is installed so that it can be switched and rotated by the outer reno ζ- (36), and the upper part of the lower part of the downflow gutter 02 is provided with a knob 07) that can be rotated. The outlet valve (to) is installed and configured so that the grains falling from the downflow gutter θ powder can be taken out and guided to the outside. A discharge gutter G'l extending toward the direction is connected to the omper 02, and a lower part of a falling gutter (4C) connected to the terminal end of the receiving gutter fb) is connected to the grain board above the brown rice conveyor (6). (41) so that the lower side of the grain plate (42) which communicates with the discharge side of the lower sorting cylinder (a) communicates with the upper part of the mixed rice conveyor (5). Install and configure.

A tank (48
) is connected to the supply side (44) of the upper sorting cylinder (A).
b) The inner VC 17) is extended as desired, and the upper part of the mixed rice thrower 04 is visible in the tank 68).

It is also possible to extend the lower part of the gutter (3rd floor as it is) and pass it through the brown rice cono hair (6) ([11]).

Therefore, due to the rotation of the rotating shaft +1111, the upper sorting cylinder (A) and the spiral conveyor □□□ rotate in the direction of the arrow (bo) as shown in Fig. 3, and both rotating wheels! 191 f19)
The rotation of the rotating shaft causes the lower sorting cylinder (a) and the spiral conveyor to rotate in the direction of the arrow.

During operation, when the Homper F121 K paddy is supplied, the mixed rice that has been dehulled and wind-selected by the dehulling section (14) falls onto the mixed rice conveyor (5) and is transferred to the mixed rice thrower -aC+. was jumped into the tank (4B) by
It is fed to the upper sorting cylinder (A) through its '1 sweet bottom opening (44).

The brown rice caught in the recess (1) of the rotating upper sorting cylinder (A) is lifted upward from between the gate valve 2++ and into the receiving gutter (G) as shown by the arrow (G).
B) The paddy that falls into the tank and is lifted upward in the same way is blocked by the gate valve Gl+ and sent in the direction of the arrow (power direction), and is sent to the delivery gutter (through the three discharge rules (b)). Tehon ζ−1,
21 and is ready to be desexed again.

As shown in Fig. 7, lower the switching valve (2) to the gutter lower part 03 side. The brown rice to be carried out flows into the lower part of the gutter C ((a)) while being guided through the switching valve (2) and is fed into the supply side of the lower selection cylinder (a). , [Y■Similarly, the rice is re-sorted by the lower sorting cylinder (&), and the rice mixed with brown rice and the ! blade is conveyed in the direction of the arrow (nu) to the grain board (42) 75 and the mixed rice conveyor (5). ) and was re-elected after being taken to Tank (43) by Mixed Rice Thrower α1 (
i', l', and on the other hand, the spiral conveyor c!
9) The brown rice conveyed in the direction of the arrow (/→ force) falls down the gutter (
4o+: The brown rice reaches the conveyor (6) via the grain board (41) and can be taken out of the machine by the brown rice thrower 1llll.

In that state, as shown in Figure 8, 1:)1C37)
However, when the take-out valve (to) is rotated outward, the brown rice falling in the downflow gutter C36 can be taken to the outer valve j by the guide of the take-out valve (to), and the inspection can be carried out. When the brown rice is completely selected, the switching valve (2) is turned to the downstream side (341 side) as shown by the imaginary line in Figure 7. The brown rice to be carried out from (B) is fed to the receiving trough (b), and can be fed to the take-out line 1 without being selected by the lower sorting cylinder (a).

In this way, the present invention provides a double rotary sorting cylinder (A) which is equipped with a receiving gutter (fE) (b) and has a large number of portions (1) large enough to fit brown rice on its inner circumferential surface. (
a) are arranged vertically in a continuous manner, and between the north sorting cylinder (A) side and the lower sorting cylinder (a) side, there is a guide for switching directly to the brown rice delivery side without re-sorting with the lower sorting cylinder (a). Switching valve that can be used (
2), the mixed rice after hulling can be sorted sequentially by the upper and lower rotating sorting cylinders (A) (a) with good performance and reliably. If the grain cannot be completely sorted, it can be switched using the switching valve (2) to send the grain to the extraction side without being re-sorted by the lower sorting cylinder (a), so that there is no waste and the grain is not damaged. It has the feature that it can be efficiently sorted and carried out, and can be carried out suitably.
