Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotational speed adjusting device for a pot-hole rotary grain sorting device of a rice hulling device.

The sorting action of the pot-hole rotary grain translating device is to feed mixed rice into a horizontally rotating cylinder provided in the grain sorting device, and form the brown rice that has sunk in the lower layer of the mixed rice, which has a higher specific gravity, on the inner surface. The process involves scooping and sorting through the hole in the pot, but with this device, unless the rotating speed of the rotating cylinder exceeds a certain level, good sorting cannot be expected.

However, when the rice hulling operation is stopped midway and the rotating cylinder is restarted, a considerable amount of mixed rice is stored in the rotating cylinder, so the rotating cylinder reaches a rotation speed higher than the specified value. It takes a considerable amount of 6 hours, and the rotation of the rotary cylinder during this time varies considerably.

This is because the rotating cylinders are placed on top of the rotating cylinders and are rotated by friction, and if a considerable amount of mixed rice is stored inside the rotating cylinders, it will be heavy and slip.

Therefore, if you try to automatically control the rotation speed of the rotary tube before the rotation speed of the rotary tube reaches the specified speed, the rotation speed of the rotary tube may pulsate more rapidly or the rotation speed of the rotary tube may drop abnormally. or

Furthermore, when the mixed rice is supplied into the rotary tube, the weight of the rotary tube increases, and it takes a longer time for the rotary tube to reach a specified rotational speed.

Therefore, the present invention shortens the time required until the rotational speed of the horizontal shaft rotational cylinder is stabilized by stopping the supply of mixed rice to the rotational cylinder until the rotational speed is stabilized, and also reduces the rotational speed. It has reduced fluctuations, and has a large number of pot holes and a large number of pot holes.

The motor 51 detects the first sensor signal after the start of operation of the horizontal axis rotating cylinder 19 by the sensor 37, 38, activates the timer circuit 57, and after a certain period of time has elapsed, is controlled by the rotation speed control circuit of the horizontal axis rotating cylinder. be done.

A thrower 54 is installed on the side of the mixed rice conveyor 14, and the thrower 54 opens onto a supply hopper 55 fixed to the end of the dissimilar grain sorting section 18. Open to. 56 is a falling port.

Next, we will discuss the effect.

When the unhulled rice is supplied to the stake hopper 2, the hulling roll 11.
The rice husks are husked at 11 and fall into a winnowing section 12, the rice husks are sucked by a suction blower 13, the mixed rice falls into a mixed rice receiving trough 16, and the immature rice falls into an immature rice receiving trough 17. Mixed rice catcher 16
The 714 rice stacking base that has fallen is transported laterally by the rice stacking conveyor 14, flows into the thrower 54, is raised, and is supplied to the supply hopper 55. Since the supply hopper 55 is open to the supply gutter 33, the supply hopper 55 is transported to the drop port 56 by the supply pipe 34, and is supplied into the horizontally rotating cylinder 19.

Since the horizontal shaft rotating cylinder 19 is rotating counterclockwise in FIG. 2, the mixed rice becomes a descending layer as it rotates, and is biased toward the rotating upward side 29. Since the lower layer of the falling layer is brown rice, the grain that fits into the pot hole 20 is brown rice, and as the horizontal shaft rotating cylinder 19 rotates, it fits and rises and falls onto the finished rice amount @ 21 to collect the finished rice. The rice is transported by the conveyor 22, falls through the take-out port 23, and is taken out from the finished rice take-out gutter 24 by the conveyor 2.
5.

After temporarily suspending the hulling grain sorting work, when the work is resumed and the power source is turned on, the feed roll 10, the hulling roll 11, 11, the rotating shaft 40 of the supply spiral 34, etc. are driven, The horizontal axis rotating cylinder 19 rotates via a belt 49 that is connected to a variable pulley 39 attached to the rotating shaft 40, but at this time, a 19% rotation speed of the horizontal axis rotating cylinder is detected by the input sensor 37 and the output sensor 38. If it is below the specified value, the solenoid 6 is energized, the horizontal rod 8 is rotated counterclockwise, and the drop 1 3 is closed by the unhulled rice delivery control valve 4 to stop the supply of unhulled rice to the hulling section 1. At the same time, the input sensor 37
, a timer circuit 57 is activated by the output sensor 38, and after a certain period of time has elapsed by the timer circuit 57, the rotation speed control circuit of the horizontal axis rotating cylinder is turned on, and the motor 51 is controlled. When the rotational speed of the horizontal rotary cylinder 19 exceeds a specified value, the input sensor 37 and the output sensor 38 stop the energization of the solenoid 6, and the supply of unhulled rice to the hulling section 1 is started.

As mentioned above, when mixed rice is stored in the rotary cylinder, such as when restarting the grain sorting machine, it takes a considerable amount of time for the rotary cylinder to reach the specified rotation speed. and,
During this period, there is considerable variation in the rotation of the rotating cylinder, and if you try to control the rotational speed of the rotating cylinder in such a starting state, the rotating cylinder may pulsate more violently or the rotational speed of the rotating cylinder may become abnormal. I'll go down. Furthermore, when the mixed rice is fed into the rotary cylinder in this state, the weight of the rotary cylinder increases, and it takes a longer time for the rotary cylinder to reach a specified rotational speed.

However, in the present invention, the rice hulling part l and the large number of pot holes 20 are
A sensor for detecting the rotational speed of the horizontal axis rotating cylinder 19 is provided at a desired position, and the first sensor signal after the start of operation is After a certain period of time has elapsed, the horizontal axis rotating cylinder 1
A rotational speed adjustment device 6 of a pot hole rotary grain sorting device in a rice hulling device that automatically controls the rotational speed of 9, and
It consists of a huller removal part 1 and a different grain sorting part 18 having a horizontal shaft rotating cylinder 19 with a large number of pot holes 20 formed on the inner surface. Since the hulling device is designed so that the raw material is not supplied to the hulling section l unless the rotational speed of the rotary barrel 19 reaches a predetermined rotational speed, the control circuit of the motor 51 is energized by the timer circuit 57. Since it operates after a certain period of time has passed and the rotation of the horizontal axis rotating cylinder 19 becomes stable, the horizontal axis rotating cylinder 1
9 pulsation and abnormal decrease in rotational speed.
When the rotation of 9 is below the specified value, the supply of unhulled rice to the huller l is stopped, so that too much mixed rice is not supplied into the rotary cylinder 19, and the rotational speed of the rotary cylinder 19 is quickly increased. It has an elevating effect.
