[Detailed description of the invention]

[0001]

Industrial Applicability The present invention detects the amount of grains in a mixed rice tank by a level sensor, and automatically adjusts the amount of sewage and the amount of air to be sifted. And a suction air volume control device.

[0002]

2. Description of the Related Art Conventionally, in a hulling sorter, a level sensor 4 provided in a mixed rice tank 3 and a hulling unit 1 inlet are controlled by a forward / reverse rotation motor 5 to increase / decrease a sliding amount. When the level sensor 5 detects that a predetermined amount or more of grains have been supplied to the mixed rice tank 3 by connecting the flow rate adjusting shutter 2 which can perform the rotation, the forward / reverse rotation motor 5 is rotated.
It is possible to adjust the opening degree of the flow rate adjusting shutter 2 to a minimum so as to reduce the sliding amount, and to automatically adjust the sliding amount so that no more grains are supplied into the mixed rice tank 3. A sliding amount control device in a possible hulling sorter is known prior to the present application (see FIG. 5) .

[0003]

By the way, in this type of apparatus shown in FIG. 5, only the adjustment of the slide-out amount is performed by the detection operation of the level sensor. Since no means for adjusting the suction separation air volume was provided, when the opening of the flow rate adjusting shutter was adjusted to the minimum position by the detection operation of the level sensor to minimize the sliding amount, it was compared with the sliding amount. As a result, the amount of suction sorting air flowing in the sorting air passage increases, and as a result, a part of the mixed rice is sucked into the suction blower and the sorting performance is deteriorated . Had the problem that

The present invention has been made in view of such a problem, and an object of the present invention is to balance the amount of grain in the mixed rice tank and the amount of sliding out by detecting operation of a level sensor. In addition to adjusting the slide-out amount to obtain the obtained amount, the suction-selection air volume is also automatically adjusted according to the slide-out amount, so that the sorting operation can be performed with the suction-selection wind of the air amount corresponding to the slide-out amount.
In selecting the hulling sorter, select the air duct and suction blower.

An object of the present invention is to provide a device for controlling the amount of sliding and the amount of suction air in a hulling sorter that can be performed efficiently.

[0005]

To achieve the above object, according to the solution to ## sliding output and suction air amount control apparatus in the hulling sorting machine according to the present invention, the level sensor kernels of mixed rice in the tank
The amount of protrusion and the amount of air for sorting air are automatically detected by the
Sliding amount and suction wind in dynamically adjusting rice hulling sorter
In the quantity control device, a flow rate adjustment shutter for adjusting the sliding amount is provided at the entrance of the hulling unit , and the suction air duct and the suction blower of the hulling sorter are vertically elongated vertically upward from the selection air path.
Connected via preparative, it opened in the middle of the suction duct outside

It is a mess .

The suction air volume adjustment control device includes a forward / reverse rotation motor rotated forward / reverse by the ON / OFF operation of the level sensor, and a helical rotation shaft rotated by the forward / reverse rotation motor.
The helical rotary shaft has a suction air volume adjustment shutter
It is an linked configure.

[0007]

[Function] At the same time as starting the hulling sorter, the grains are put into the hulling tank. By the way, at the time of starting the operation, since the mixed rice is not supplied into the mixed rice tank, the level sensor is kept in the OFF state, the flow rate adjusting shutter is at the maximum opening position, and the suction air volume adjusting shutter is at the minimum. Each is set at the opening position.

Accordingly, a large amount of grains supplied from the paddy tank to the pair of paddy rolls through the flow rate adjusting shutter are slid out one after another, then supplied to the sorting air path, and mixed by the circulating suction sorting wind. Rice, crushed rice and rice husk are air-sorted, and the mixed rice is supplied to the mixed rice tank via appropriate transport means,
The waste rice is collected outside the machine, and the rice husks are crushed and sorted out through a suction duct and a suction blower.

By the way, during the above-mentioned paddy sorting operation, when the supply amount of the mixed rice into the mixed rice tank becomes larger than the discharge amount of the mixed rice tank and the level sensor is turned on, the detection signal of the level sensor is detected. The flow rate adjusting shutter is automatically moved from the maximum opening position to the minimum opening position, and the suction air volume adjusting shutter is automatically moved from the minimum opening position to the maximum opening position. Controlled.

[0010] As a result, the supply amount from the paddy tank to the pair of hulling rolls is reduced, and the sliding amount is accordingly reduced, and the supply amount to the mixed rice tank is reduced. Is prevented from accumulating in the mixed rice tank, and the amount of sorting air passing through the sorting air passage is reduced to match the amount of sliding. Therefore, since the small amount of the smashed rice supplied to the sifting air path is sifted by the balanced sifting wind, a part of the smashed rice is sucked into the suction blower and discharged outside the machine. that no, it is possible intends line the hulling selection work.
