DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an automatic feed control method and device for a rice huller.

(Prior Art) A conventional rice hulling machine that automatically adjusts the appropriate supply amount at all times is known.

(Means for Solving the Problem) The present invention has a simple configuration and is capable of automatic control.

An embodiment of the present invention will be described with reference to the drawings. In FIG. 1, l is a supply elevator, and a packet conveyor 2 is mounted inside thereof. Reference numeral 3 denotes a stake hopper attached to the lower part of the supply elevator Al, and a stake shutter 4 is attached to the stake hopper 3.

5 is a rack formed on the shutter 4, and a motor 6
The pinion 8 attached to the shaft 7 of is engaged with the rack 5.

The motor 6 is operated by an upper limit level switch 17 and a lower limit level switch 18, which will be described later.

A supply tank 9 is provided at the upper part of the supply elevator 1. 10
is an overflow pipe. A roll upper shutter 12 is attached to the drop port 11 at the lower end of the supply tank 9.

13 is a rack 13 formed on the lower surface of the roll upper shutter 12, and a pinion 16 attached to the shaft 15 of the motor 14 is engaged with the rack 13. 17 is supply tank 9
The upper level switch 18 provided inside is the lower limit level switch 18 provided below the upper limit level switch 17. The upper limit level switch 17 and the lower limit level switch 18 are connected to the motor 6 and the motor 14, and the lower limit level switch 18 When the level is below, the motor 6 is energized to open the tension shutter 4, and when the upper limit level switch 17 is reached, the motor 6 is energized to rotate the pinion 8 and the tension shutter 4 is closed, and the motor 14 is energized again. Open the roll upper shutter 12.

Reference numeral 19 denotes a paddy sensing switch provided at the dropping port 11, 20 a feed roll, 21 a main roll, and 22 a sub roll.The sub roll 22 is brought into contact with and separated from the main roll 21 by a motor 23.

In addition, 24 is a rice sensing plate, 25 is a rice huller, and the third
To explain the embodiment in the figure, 26 is a supply conveyor;
27 is a motor that rotates the supply conveyor 26;
It is the same as the motor 6 in FIG. 28 is paddy sorting department, 2
9 is a suction blower, 30 is an exhaust port, 31 is a mixed rice outlet,
32 is an elevator, 33 is a switching valve, and 34 is a return tank.

(effect) Next, we will discuss the effect.

To explain this with reference to the flowchart in FIG. 2, before the work, the lower limit level switch 18 is not sensing paddy, so the motor 6 is energized, the pinion 8 is rotated counterclockwise, and the tensioning shutter 4 is turned on. is opened, the unhulled rice in the hopper 3 flows into the elevator l, and the packet conveyor 2
The grains are fried and stored in the supply tank 9.

(In Fig. 3, before the work, the lower limit level switch 18 in the supply tank 9 is not sensing paddy, so the solenoid of the staking shutter 4 is energized and the staking hopper 3 is
The unhulled rice in the hopper 3 is dropped onto the supply conveyor 26, and the motor 27 is energized to rotate the supply conveyor 26, and the unhulled rice in the stake hopper 3 is flowed into the vertical ml and then fried by the bucket conveyor. , stored in the supply tank 9.

) When the paddy stored in the supply tank 9 reaches the upper limit level switch 17, the motor 14 is energized to rotate the pinion 16 clockwise, the roll upper shutter 12 is opened, and the paddy falls from the drop opening 11 and is repeatedly dumped. It is supplied to a main roll 21 and an auxiliary roll 22 by a loading roll 20. At the same time, the motor 6 is energized, the pinion 8 is rotated clockwise, and the tensioning shutter 4 is closed.

(In FIG. 3, when the paddy stored in the supply tank 9 reaches the upper limit level switch 17, the solenoid of the tensioning shutter 4 is energized to close the tensioning shutter 4, and the motor 27 is energized to supply the (The conveyor 26 is stopped.) At this time, the paddy sensing plate 24 detects the dropping of paddy, so it energizes the motor 23 and moves the sub roll 22 to the main roll 21.
Hull the rice close to the direction.

(Effects) In the present invention, when the unhulled rice is stretched into the supply tank 9 of the hulling section 25, and when the unhulled rice does not reach the lower limit level switch 18 in the tank 9, the opening/closing device of the tensioning shutter 4 of the supply section is used. The shutter 4 is opened to supply unhulled rice, and when the unhulled rice is supplied into the tank 9 and reaches the upper limit level switch 17, the shutter 4 is closed by the opening/closing device, and the shutter is closed by the opening/closing device of the roll upper shutter li. Automatic supply control method in a hulling machine which opens the huller 12 to hull the rice, and a supply tank for the hulling part that supplies hulled rice to the hulling part 25 by providing a tension shutter 4 in the supplying part of the elevator 1 for supplying unhulled rice. An upper limit level switch 17 and a lower limit level switch 18 are provided in the tank 9, and a roll upper shutter 12 is provided at the bottom of the tank 9, and when the unhulled rice in the tank 9 does not reach the lower limit level switch 18, the shutter 4 is opened. , the upper limit level switch 1 is set so that when the unhulled rice in the tank 9 reaches the upper limit level switch 17, the stake-in shutter 4 is closed and the roll upper shutter 12 is opened.
7, the lower limit level switch 18, the tensioning shutter 4, and the roll upper shutter 12 are connected to each other in an automatic feed control device for the hulling machine, so that the appropriate amount of unhulled rice is always automatically supplied to the hulling section 25. It has the effect of being able to be supplied and work can be carried out smoothly.
