The rice nucles selection unit 200 is for sorting the rice nucles separated from rice bran through the rice bran purification unit 100 by size. The rice grain separator 200 includes a frame 210; A bracket 220 coupled to both sides of the frame 210 and having an elongated inclination angle adjusting hole 221 formed therein; A support table 230 movably coupled along the inclination angle adjusting hole 221 of the bracket 220; A forward and backward member (240) supported by a support base (230); A screen 250 provided inside the forward / backward member 240; A spring 260 installed between the forward-backward member 240 and the screen 250; A driving body (270) for moving the forward / backward member (240) back and forth; And a vibration motor 280 installed on the screen 250.

The frame 210 is for supporting the bracket 220 firmly and has a structure in which a plurality of bars are connected to each other.

The brackets 220 are installed at two spaced intervals on the bars 210 on both sides of the frame 210, and the number of the brackets 220, the number of the brackets 220, and the installation position thereof can be appropriately adjusted as necessary.

The support base 230 serves to support the forward / backward member 240 so as to be movable back and forth.

The support base 230 includes a bolt portion 231 penetrating the inclination angle adjusting hole 221 of the bracket 220; A roller mounting portion 232 integrally joined to the bolt portion 231; A roller portion 233 rotatably installed on the roller mounting portion 232 and supporting the forward / backward member 240; And a nut portion 234 fastened to the bolt portion 231 and tightly supported by the bracket 220.

The roller portions 233 are formed as a pair and are spaced apart from each other, and the forward / backward member 240 is interposed between the pair of roller portions 233. Accordingly, the operation state of the forward / backward member 240 can be maintained smoothly and stably.

The inclination angle of the screen 250 can be adjusted by adjusting the position of the bolt portion 231 provided through the inclination angle adjusting hole 221 of the bracket 220. 7, the fastening state of the nut portion 234 is released to allow the bolt portion 231 to move along the inclination angle adjusting hole 221 of the bracket 220, and the bolt portion 231 is inserted into the inclination angle adjusting hole 221 And then the nut portion 234 is firmly fixed to the bracket 220 so that the nut portion 234 is firmly fixed to the bracket 220. The inclination angle of the screen 250 is adjusted.

The forward / backward member 240 is formed in the shape of "? &Quot;, and is moved back and forth in a state where both sides thereof are interposed between the roller portions 233. Of course, the front surface of the forward / backward member 240 is connected to the driving body 270.

The screen 250 which is interlocked with the forward / backward member 240 is oscillated.

Meanwhile, since the structure of the driving body 270 is a well-known technique, a detailed description thereof will be omitted.

The vibration motor 260 generates vibrations in the screen 250, and the installation position and the number of the vibration motors 260 can be variously changed.

The process of selecting rice gins through the rice grit screening apparatus described above will be briefly described as follows.

First, rice husk separated from the rice bran through the first, second, and third refineries 110, 130 and 130 of the rice bran refinery 100 is supplied to the rice bran separator 200, The supplied rice grain is sorted and discharged through the first screen 251, the second screen 252 and the third screen 253.

At this time, the first, second, and third screens 251, 252, and 253 are rocked by the forward and backward members 240 and the vibration motor 280 that are operated forward and backward by the drive body 270.

On the other hand, when the inclination angle of the first, second and third screens 251, 252 and 253 is to be adjusted, the mounting position of the support table 230 coupled to the inclination angle adjusting hole 221 of the bracket 220 may be adjusted .
