Blower 17 is contacted via.

Reference numeral 25 is an upper conveyance device, which is a screw conveyor shaft.
A helix 27 is wound around 26. The lower end of the screw conveyor shaft 26, which is interlocked in a vertically slidable manner, is fitted to the upper end of the friction polishing trochanter 6 with a key 28. Then, the resistance device 31 is provided on the lower portion of the spiral body 27 by the coupling pin 30. The resistance device 31 includes a resistance plate 32 and a cylindrical body 34 in which a spiral body 33 is wound. Reference numeral 35 is an elongated hole-shaped void provided in the screw conveyor shaft 26. A compression degree adjusting device 36 is provided on the upper part of the screw conveyor shaft 26,
Via a connecting rod 37, a spring base 38, and a spring 39, it is connected to an adjusting screw rod 41 to which a handle 40 is attached. And, in order that the screw conveyor shaft 26 can be interlocked vertically slidably, the bearing base 29
A spring 43 is connected to the machine frame 42.

A scraping blade 44 is provided on the upper part of the screw conveyor shaft 26, and a discharge gutter 46 is connected to a refined product discharge port 45 of the upper transport device 25. The discharge gutter 46 is rotatably formed by a forward / reverse rotation motor 47, and the rice collecting gutter 48 communicates with the supply gutter 12 via a return gutter 49.

Next, the operation of the above configuration will be described. When the motor 14 is driven, the brown rice in the brown rice tank 10 flows down the bottom plate 11 and is sent from the supply gutter 12 to the spiral rotator 4 via the brown rice supply unit 8. Brown rice is sent to the polishing room 7 by the spiral trochanter 4,
The frictional whitening trochanter 6 is subjected to the polishing action caused by the rotation and is refined. Then, the bran is sucked from the air suction passage 22 by the blower 17 and blown out from the jet port 23 to remove bran. Dust such as bran generated by the polishing action in the polishing chamber 7 is discharged from the through hole of the porous wall removing bran polishing cylinder 2 to the removing bran chamber 24, and the blower 17 and the bran discharge port 19 from a removing bran duct (not shown). Then, it is sent to the cyclone 21 through the bran discharge pipe 20 and collected.

The polished rice reaches the polished rice discharge portion 9 and flows out against the resistance plate 32 while being prevented from flowing out by the resistance plate 32.
Then, the white rice is fed upward in the upper conveying device 25 by the spiral body 27 of the screw conveyor shaft 26, and the white rice reaching the upper end is promoted to be discharged by the scraping blades 44, and the refined product discharge port
After passing through 45, it is discharged from the discharge gutter 46 into a container provided outside the machine.

Immediately after the start of polishing, incompletely polished rice is discharged from the discharge gutter 46.
To circulate the unpolished rice by reversing it to the position of the chain line (1st
See figure). In other words, unpolished rice is collected from the refined product outlet 45
It drops to 48 and returns through the supply gutter 49 to the supply gutter 12 to the brown rice supply part 8
Is sent to and is re-energized. Then, after a certain period of time, when the proper lapping accuracy is reached, the forward / reverse rotation motor 47 is operated to reverse the discharge gutter 46 to the position indicated by the solid line, and the white rice is discharged from the discharge gutter 46 into a container provided outside the machine. .

Next, the operation of adjusting the accuracy of the hammer will be described. Pressure adjustment device
When the handle 40 of 36 is rotated, the adjusting screw 41 is rotated and lowered. The pressure is transmitted to the screw conveyor shaft 26 via the spring 39, the bearing base 29, and the connecting rod 37, and the screw conveyor shaft 26 is lowered by the spring 43 connecting the bearing base 29 and the machine frame 42. The resistance plate 32 descends from the white rice discharging section 9 because the screw conveyor shaft 26 and the resistance plate 32 are connected to each other. For this reason, the degree of suppression of the outflow of white rice is increased to improve the accuracy of grinding, and when the accuracy of grinding is reduced, the reverse operation is performed. Further, when the polished rice is discharged from the polished rice discharge portion 9 and is sent upward, the spiraling body 33 wound around the cylindrical body 34 of the resistance device 31 promotes the upward feeding action and prevents stagnation.

In addition, if the amount of brown rice decreases as the polishing work proceeds, unpolished rice will be discharged and unpolished rice will be discharged to the outside of the machine. Therefore, the sensor 50 provided on the bottom plate 11 detects the decrease of brown rice, and the signal from the sensor 50 causes the forward / reverse rotation motor 47.
Is activated, the drain gutter 46 is inverted to the position indicated by the chain line (see FIG. 1). Then, the unpolished rice is returned to the brown rice supply unit 8 through the return gutter 49 (not shown) and re-polished. Then, the rice grain circulated until it reaches an appropriate straining accuracy is discharged to a container provided outside the machine by operating the forward / reverse rotation motor 47 by a timer or the like to reverse the discharge gutter 46 to the position indicated by the solid line.

In the embodiment described above, since the refined product discharge port 45 for discharging white rice is provided at a high position, the rice removal container (for example, a paper bag) can be upsized, and the container need not be replaced frequently. .
