Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a residual rice discharging device in an upright vertical rice milling machine.

(Prior Art) Japanese Patent Laid-Open No. 57-130554 or Japanese Patent Laid-Open No. 60-19042 discloses a basic structure of a lifting type vertical rice milling machine.

Further, in the publicly known Japanese Utility Model Publication No. 59-154378, a vertical grain sorter for sorting grains such as rice while frying the grains is provided with feed ports at upper and lower intermediate positions of a vertical cylinder. A configuration is described in which a residual rice outlet is formed above the bottom of the vertical cylinder below the supply port, and a lid is provided at the residual rice outlet. The reason for installing a lid on the residual rice outlet is that grains will scatter without the lid.

(Problems to be Solved by the Invention) Among the above-mentioned publicly known examples, the one described in Japanese Utility Model Laid-Open No. 59-154378 has a cylinder in which rice flowing in from a supply port is a cylinder as shown in FIG. Since it is supplied directly onto the bottom of the bottom of the rice, if you forget to close the residual rice outlet with the lid open, you will lose the grains scattered by the centrifugal force of the spiral blade from the residual rice outlet. There is a problem of spilling. If the rice grains scatter, they enter the bottom of the device and cannot be cleaned, which causes pests.

This problem of forgetting to close the lid can be solved by setting the position of the residual rice removal port to a position a below the supply port. If the position is set to a position lower than the supply port, grain spill does not occur even if the lid is not closed, so that the lid becomes unnecessary. The remaining rice may be discharged by reversing the upper feed helix.

(Means for Solving the Problem) Therefore, according to the present invention, a vertical shaft 2 that rotates forward and backward by a forward / reverse driving motor 8 is provided in the vertical cylinder 1, and an outer periphery of the vertical shaft 2 is upward when normal rotation is performed. The spiral 3 for feeding is attached, and the feed port 5 is formed at an intermediate position in the vertical direction of the vertical cylinder 1 so that the grain flowing in from the feed port 5 is fed forward by the forward rotation of the spiral 3. Grains are not discharged as long as the spiral 3 is normally rotated below the position 5. A residual rice attachment opening 7 that is open without a lid is provided, and the spiral 3 is reversed to remove the residual rice removal opening 7 It is a residual rice discharging device in a rising type vertical rice mill that lowers and takes out.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings, in which 1 is a vertical cylinder in which a vertical shaft 2 is mounted. An upper feed spiral 3 is provided on the outer circumference of the vertical shaft 2. A supply port 5 is opened at an intermediate position in the vertical direction of the vertical cylinder 1, and a hopper 6 is attached to the outside of the supply port 5.

When the upper feed spiral 3 is in the normal rotation at a position lower than the supply port 5, the rice grain flowing in from the supply port 5 is raised by the upper feed spiral 3 and is not discharged. When 3 is rotated in the reverse direction, the residual rice removal port 7 is formed at a position where it is lowered and discharged. The residual rice removal port 7 may be provided with an on-off valve, but need not be provided.

FIG. 2 is a circuit diagram of the motor 8 for rotating the vertical shaft 2. Reference numeral 9 is a forward rotation stop push button switch, 10 is a forward rotation start push button switch, 11 is a timer contact of a timer motor 18, and 12 is a Relays 13 are relay contacts of the relay 12. When the forward rotation start pushbutton switch 10 is turned on, a current flows through the relay 12 via the timer contact 11 to turn on the relay contact 13. After that, the switch 1
Even if 0 is turned off, the forward rotation stop push button switch 9 → relay contact 13 → timer contact 11 → relay 12 flows and self-holds. The self-holding is turned off when the switch 9 is turned off.

Further, 14 is a push button switch for reverse rotation start, 15 is a relay, 16 is a relay contact of the relay 12, 17 is an operation contact of the brown rice detection sensor 21, 19 is a relay contact of the relay 12, and 20 is a relay contact of the relay 15. .

(Operation) Next, the operation will be described.

When brown rice is supplied from hopper 6, brown rice detection sensor 2
1 detects brown rice, and its operating contact 17 is switched to the terminal b side. Therefore, when the forward rotation start push button switch 10 is turned on, a current flows through the forward rotation stop push button switch 9 → the forward rotation start push button switch 10 → the timer 11 → the relay 12, and the relay contact 13 of the relay 12 , The relay contact 16 and the relay contact 19 are both turned on.

Therefore, the motor 8 rotates normally, and the vertical shaft 2 rotates normally,
The grain fed from the supply port 5 is raised by the upper feed spiral 3 to polish rice, but the residual rice outlet 7 is formed at a position a below the supply port 5, so the upper feed spiral 3 rotates normally. Grain from the supply port 5 is the residual rice removal port 7
Grains are not discharged even if the remaining rice outlet 7 is left open without a lid as shown in FIG.

When the grain disappears, the brown rice detection sensor 21 detects this and the operation contact 17 returns to the terminal c side, the timer motor 18 is energized, and after a predetermined time elapses, the timer contact 11
Is turned off and the relay 12 is turned off, so that the relay contact 13, the relay contact 16, and the relay contact 19 are all turned off, and the motor 8 is stopped.

Then, when the reverse rotation start push button switch 14 is turned on, the relay 15 is energized and the relay contact 20 is turned on. Therefore, the motor 8 reverses to lower the grain by a and the residual rice outlet 7 at the lower position You can take out the grain.
The reverse rotation of the vertical axis 2 is limited only to the time when the reverse rotation start push button switch 14 is pressed.

(Effect) As described above, in the rice disclosed in Japanese Utility Model Laid-Open No. 59-154378, as shown in FIG. 2, the rice that has flowed in through the supply port is at the bottom of the bottom of the cylinder. Since it is supplied directly to the top, if you forget to close the remaining rice outlet lid and forget to close the rice, the grains scattered by the centrifugal force of the spiral blade will spill out from the residual rice outlet. . If the rice grains scatter, they enter the bottom of the device and cannot be cleaned, which causes pests.

However, according to the present invention, a vertical shaft 2 that rotates forward and backward by a forward / reverse driving motor 8 is provided in the vertical cylinder 1, and a spiral 3 that feeds upward in the normal rotation is attached to the outer periphery of the vertical shaft 2. A feed port 5 is formed at an intermediate position in the vertical direction of the vertical cylinder 1 so that the grain flowing in from the feed port 5 is fed upward by the normal rotation of the spiral 3, and the spiral 3 is placed at a position a below the feed port 5. Grain is not discharged as long as it is rotating in the normal direction. An upright vertical type is provided with an open residual rice outlet 7 without a lid, and the spiral 3 is reversed to lower the grain to the residual rice outlet 7 and take it out. Since the residual rice discharging device is used in the rice polishing machine, the residual rice discharging port 7 is at a position a below the supply port 5 where grain is not discharged as long as the spiral 3 is normally rotated. Residual rice outlet 7
Therefore, the problem of scattering does not occur because the user does not forget to close the lid of the residual rice removal port 7, and thus the problem does not occur. The residual rice is taken out by reversing the spiral 3 and lowering the grain, so that it is easy to handle.
