Description

[Detailed Description of the Invention] The present invention relates to a wheat removal device in a hulling plant.

In other words, this system makes it possible to remove wheat that gets mixed in with rice in a sorting process at a rice hulling plant.
To provide a system that can be suitably implemented in rice hulling plants, by detecting the rice husks and wheat that are sorted out by a oscillating sorter and automatically switching to the wheat receiving side when the amount of wheat increases, thereby enabling the system to automatically and effectively discharge and remove the wheat without the need for manual discharge operations while monitoring.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a system diagram of a hulling plant, in which the upper part of a rice lifting machine 4 having a hopper 3 at the lower part is connected to the upper hopper 6 of a hulling machine A having a dehulling roll 5, etc.
A mixed rice elevator 8 is installed so as to communicate with the upper hopper 9 of the oscillating sorter B, and has a hopper 7 at its lower part that communicates with the huller A. The upper part of a brown rice elevator 11 having a hopper 10 in its lower part that communicates with the brown rice outlet 2 of the sorting machine B is installed to communicate with a rice sorter 12, and the quality brown rice has a hopper 13 in its lower part that communicates with the rice sorter 12. The upper part of the elevator 14 is installed to communicate with the tank 15, and the weighing machine 16 is installed below the tank 15.
The brown rice bag 17 is installed and configured so that bagging can be carried out under the brown rice bag 17.

As shown in FIGS. 2 to 5, the oscillating sorter B tilts a grain sorting plate 1 having a rough surface 1a on the upper surface in a long vertical direction Y and a short horizontal direction X, and stacks a plurality of grains. , these are supported by lower swinging supports 18, and each grain selection plate 1 is installed so as to swing in the lateral direction X by an eccentric wheel-driven swinging arm 19.
A supply tank 20 connected to the upper side of each grain sorting board 1 with an inclination in the vertical direction is installed so as to look below the upper hopper 9, and is installed below the end of the lower end of the incline in the vertical direction of each grain selection board 1 with an incline of Y in the vertical direction. On the side, two partition plates 21 and 22 are installed at two positions in the horizontal direction and are movable and adjustable in the horizontal direction using knobs 23 and 24, respectively.
1 and 22, three outlets are respectively installed in the lower part thereof, and the structure is similar to the conventional structure of this type.

Outlet 2, which is one side of the three outlets and from which brown rice comes out, is the hopper 1 of the brown rice elevator 11 as described above.
0, and the intermediate outlet E from which the mixed rice comes out is installed to communicate with the hopper 7 of the mixed rice elevator 8, and the outlet A on the other side from which the paddy and wheat come out has a switching valve 2. The switch section C has a two-pronged structure that branches into two outlets B and C, and one outlet B is used as a wheat receiving side and a bag 25 is attached below it, and the other outlet C is connected to the hopper of the paddy elevator 4. 3, and the switching valve 2 is connected to a telescoping rod 27 extending and retracting from the solenoid 26, and is installed so as to be able to rotate for switching. is equipped with a color sensor S that can detect and discriminate the color difference between paddy and wheat and operate.
The solenoid 26 is actuated via the control box 28 in response to a signal from the control box 28, so that the switching valve 2 can be switched.

When the paddy mixed with wheat is fed to the hopper 3 as shown by the arrow N, the paddy is dehulled by the huller A, and then sent to the shaking sorter B where it is sorted by shaking. The brown rice is sent to the rice sorter 12 side from outlet d, and the mixed rice is returned to the oscillating sorter B from outlet e and is sorted.

In addition, although paddy and wheat are sent out from outlet A, when the amount of wheat is small, the solenoid 26 is activated by the detection discrimination of the color sensor S, and the switching valve 2
rotates to the exit B side, and the paddy is transferred from the exit C to the huller A.
When the amount of wheat increases, the solenoid 26 is actuated by the detection of the color sensor S, the switching valve 2 is switched to the outlet C side, and the wheat is transferred from the outlet B to the bag 25. It leaks out and is taken out.

In this way, the present invention connects the oscillating sorter B, which is constructed by making the grain selection plate 1 swingable and tilted with the rough surface 1a, as a downstream process of the husking machine A. The paddy and wheat outlet A at B is connected to the switching valve 2.
One outlet B of the switching part C is connected to the wheat receiving side, and the other outlet C is connected to the hulling machine A so that the switching part C can be carried out.
is equipped with a color sensor S capable of detecting and distinguishing the colors of paddy and wheat, and is also equipped and configured so that the sensor S can operate the switching valve 2, so that the grains are sorted by the swinging sorter B and then passed to the exit point. The color sensor S detects the paddy and wheat that are coming out, and if there is a lot of paddy, it can be sent from the exit C to the huller A, and if there is a lot of wheat, it can be sent from the exit B.
The switching discharge can be performed automatically, and the wheat can be discharged and removed automatically without manual discharge operation while monitoring.
It has characteristics that can be suitably implemented in a rice hulling plant.
