Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a de-stoning device in a coin rice milling device.

(Prior Art) A typical example of a conventionally known stone removing device is shown in FIG. When the plate fan b is rotated in the direction of the arrow at the suction port drilled in the side of the plate, air is sucked in through the suction port c and blown upward. d is an air outlet formed on the upper surface of the wind body case a, and a swing sorting plate e is attached to the upper part of the air outlet d. The swing sorting plate e has a frame f that moves diagonally up and down as shown by the arrow, g is a wire mesh stretched on the bottom of the frame f, and the eye h is a wire mesh that blows the wind in the direction of the stone extraction port i. It is formed into a structure. j is the grain outlet.

In the known method, if grains are fed from above,
Grain A receives the wind blowing up the wire mesh g, floats above the wire mesh g by a distance t, and stops there, as shown in Figure 2. Since the grain outlet j is lower, the grain tries to go down towards the grain outlet j, but due to the influence of the wind blowing up the grain h, it tends to move towards the stone outlet i. .

When new succeeding grains are additionally fed from above, the added portion spreads out horizontally as shown in Figure 1. Therefore, when succeeding grains are fed one after another, the amount of grain that is added will be removed from the grain outlet by that amount. It can be taken out from j.

Since the stone chips are heavy, they do not float up, but directly contact the wire gauze g, so that they are stirred up in the w direction, move toward the stone removal port i direction, and are taken out.

(Problems to be Solved by the Invention) The disadvantage of the known example shown in FIG. 1 is that the grains remaining on the plate surface are not automatically discharged separately from the stone chips, so it cannot be applied to a coin rice milling device.

That is, the remaining rice often remains on the wire gauze g and does not move, and it is common to sweep it out with something like a broom, but the grain and stones are mixed together.

As shown in FIG. 3, when the rotation of the plate fan b is stopped, the grains A no longer float, so they stick tightly onto the wire gauze g. Therefore, the wire mesh g moves in the direction of the stone outlet i due to the pushing up movement in the w direction, and the wire mesh g moves in the direction of the stone outlet i.
It can be taken out. In this case too, grain and stone are mixed.

Therefore, if used in a coin rice mill, stone chips will be mixed into the product.

(Means for solving the problem) Therefore, the present invention turns off the power when a coin is inserted.
In a coin rice milling device that is turned ON to mill a certain amount of rice, the discharge section 2 of the rice milling section 23 of the rice milling device
6 is connected to a stone removing device 24, and the stone removing device 24 passes the remaining rice on the sorting plate 12 over the stone waste in the stone removal passage 10 and discharges the entire amount to the grain discharge side 8. This is the configuration of a extraction device.

(Example) (1) Overall structure 23 is a rice milling section, which has a first hopper 27 and a second hopper 28 in the upper part, and has a discharge part 26 in the lower part. 29 is a rice milling room, in which a stone removing device 24 is provided below the discharge section 26, and a grain frying device 25 is provided on the side. The grain lifting device 25 is provided with a loading hopper 30 and a spare hopper 31. 32 is an on-off valve for the loading hopper 30, 33 is an on-off valve for the preliminary hopper 31, 34
is an operating piece, 35 is a switch, 36 is a switch, 3
7 and 38 are containers, 39 is a switch, and 40 is an operating piece.

(2) Structure of the stone extraction part 1 is the entire case, and the wind barrel case 2 is fixed inside. The wind body case 2 has an inlet 3 on the side,
The upper surface is open and formed into an air outlet 4. A wind turbine 5 is pivotally mounted inside the wind barrel case 2. The windmill 5 is a swinging frame 6 attached above the air outlet 4, and the left and right sides are provided with vertical walls 7, 7, the rear side is fully opened to form a grain outlet 8, and the front side is a front end. A tapered part 9 is formed which becomes narrower as it reaches the end, and a stone removal passage 10 is formed at the front end. A wire mesh 12 is stretched over the bottom surface of the swinging frame 6 and has holes 11 for blowing air in the direction of the stone removal path 10. Stone passageway 10
A stone fall opening 13 is provided in the middle, and a stone fall opening 1 is provided.
A drop tube 14 is attached below 3. A grain return port 15 is provided at the tip of the stone removal path 10, a sink plate 16 inclined laterally is attached to the grain return port 15, and the front end of the return path 17 is connected to the lower end of the sink plate 16. The rear end is opened 18 on the side of the grain outlet 8. A rotating shaft 19 is provided above the stone falling port 13, and the rotating shaft 19 has a stone falling port opening/closing valve 20 for opening and closing the stone falling port 13 and a falling tube opening/closing valve for opening and closing the lower end of the falling tube 14. 21 will be provided.

The stone falling opening opening/closing valve 20 and the falling tube opening/closing valve 21 are such that when the stone falling opening opening/closing valve 20 is in the closed position, the falling tube opening/closing valve 21 is in the open/closed position;
When opened, the drop tube opening/closing valve 21 is in the closed position.

Further, when the stone fall opening opening/closing valve 20 is in the open position, grains pass through the lower part thereof. 22 is a motor.

(effect) Next, we will discuss the effect.

Activate the grain lifting device 25 to load the hopper 30,
When the spare hopper 31 is lowered, the tensioning hopper 30 collides with the switch 36, causing the switch 36 to
Turn it on. Then, the motor 41 rotates, and the shaft 4
Rotate 2. Then, when the brought brown rice is put into the tensioning hopper 30, the grain frying device 25 is rotated by the operation of the timer, the tensioning hopper 30 is raised, and the opening/closing valve 32 comes into contact with the first abutment body 43 and opens. Therefore, the entire amount of rice flows from the loading hopper 30 to the first hopper 27, is polished in the rice milling chamber 29, and is discharged from the discharge section 26. At this time, the actuating piece 40 is pressed and turns on the switch 39, so the grain frying device 25
rotates, and the tensioning hopper 30 and the spare hopper 3
1 is moved downward to the state shown in FIG.
1.

When the preliminary hopper 31 is full of half-pounded rice, the actuating piece 34 is pressed to turn on the grain lifting device 25, causing the grain lifting device 25 to rotate again and rise as shown in FIG. 10. Then, the on-off valve 33 hits the second abutting body 44 and opens the on-off valve 33, so the preliminary hopper 3
All of the half-pounded rice from No. 1 flows into the second hopper 28.

Therefore, when the brown rice in the first hopper 27 runs out, the half-pounded rice in the second hopper 28 is subsequently polished in the rice milling chamber 29 and flows into the destoning device 24 from the discharge section 26. Therefore, all of the brown rice put into the hopper 30 is polished in the rice milling room 29, and all the grains flow into the destoning device 24.

When the rocking frame 6 of the stone removing device 24 is rocked in the direction of the arrow w using a known rocking mechanism, the wind from the windmill 5 blows obliquely upward through the eyes 11, separating the grains from the stones, and turning the grains into grains. The stone chips are taken out at the outlet 8, guided by the side walls 7 and the tapered part 9, and reach the stone removal passage 10, where they are deposited in front of the stone drop opening opening/closing valve 20 in the closed position.

As this work continues, the supplied grains will run out, but the sensor detects this fact, activates the motor 22 to rotate the rotating shaft 19, and turns the stone drop opening opening/closing valve 20 and the dropping cylinder opening/closing valve 21. When the stone falling port 13 is opened and closed by the lower end of the falling tube 14, the stone debris is removed from the stone falling hole 13.
It flows into the drop tube 14 and accumulates therein. However, as shown in Fig. 7, the stone fall opening opening/closing valve 2
Since the lower end of the grain return port 15 is opened to open the grain return port 15, the grains pass over the stone chips, pass through the grain return port 15, pass through the sink plate 16, go through the return path 17, and are taken out from the return opening 18.

Then, the motor 22 is energized and the stone falling port 1 is turned on again.
3 and open the drop tube opening/closing valve 21, the drop tube 14
The stone debris inside is taken out to the outside.

(Effects) A typical example of a conventionally known stone removal device is shown in Fig. 1, where a is a wind cylinder case, b is a plate fan installed in the wind cylinder case a, and c is a plate fan installed in the wind cylinder case a. When the plate fan b is rotated in the direction of the arrow through the suction port drilled in the side, air is sucked in through the suction port c and blown upward. d is an air outlet formed on the upper surface of the wind body case a, and a swing sorting plate e is attached to the upper part of the air outlet d. The swing sorting plate e has a frame f that moves diagonally up and down as shown by the arrow, g is a wire mesh stretched on the bottom of the frame f, and the eye h is a wire mesh that blows the wind in the direction of the stone extraction port i. It is formed into a structure. j is the grain outlet.

In the known method, if grains are fed from above,
Grain A receives the wind blowing up the wire mesh g, floats above the wire mesh g by a distance t, and stops there, as shown in Figure 2. Since the grain outlet j is lower, the grain tries to go down towards the grain outlet j, but due to the influence of the wind blowing up the grain h, it tends to move towards the stone outlet i. .

When new succeeding grains are additionally fed from above, the added portion spreads out horizontally as shown in Figure 1. Therefore, when succeeding grains are fed one after another, the amount of grain that is added will be removed from the grain outlet by that amount. It can be taken out from j.

Since the stone chips are heavy, they do not float up, but directly contact the wire gauze g, so that they are stirred up in the w direction, move toward the stone removal port i direction, and are taken out.

The disadvantage of the known example shown in FIG. 1 is that the grains remaining on the plate surface are not automatically discharged separately from the stone chips, so it cannot be applied to a coin rice milling device.

That is, the remaining rice often remains on the wire gauze g and does not move, and it is common to sweep it out with something like a broom, but the grain and stones are mixed together.

As shown in FIG. 3, when the rotation of the plate fan b is stopped, the grains A no longer float, so they stick tightly onto the wire gauze g. Therefore, the wire mesh g moves in the direction of the stone outlet i due to the pushing up movement in the w direction, and the wire mesh g moves in the direction of the stone outlet i.
It can be taken out. In this case too, grain and stone are mixed.

Therefore, if used in a coin rice mill, stone chips will be mixed into the product.

However, in the present invention, when a coin is inserted, the power is turned off.
In a coin rice milling device that is turned ON to mill a certain amount of rice, the discharge section 2 of the rice milling section 23 of the rice milling device
6 is connected to a stone removing device 24, and the stone removing device 24 passes the remaining rice on the sorting plate 12 over the stone waste in the stone removal passage 10 and discharges the entire amount to the grain discharge side 8. Since it is a removing device, the entire amount of coin-milled rice can be removed from the stones, and no residual rice is left.
