A hulling device is known that includes a brown rice flow path and a paddy rice flow path that are disposed close to each other between the dissimilar grain sorting section and the wind sorting section.

(Problems to be Solved by the Invention) In the known hulling device, since the brown rice flow passage and the unhulled rice flow passage are arranged close to each other, the unhulled rice flowing down the unhulled rice flow passage may be mixed into the brown rice flow passage. .

That is, when the wind selection section is provided below the hulling section and the different grain sorting section, the brown rice flow passage and the unhulled rice flow passage of the different kind grain sorting section are connected to the brown rice flow passage and the unhulled rice flow passage of the wind selection section. During assembly, if the positions of the dissimilar grain sorting section and the wind sorting section are even slightly shifted, the unhulled rice downflow path overlaps with the brown rice downflow path, and unhulled rice gets mixed in.

In addition, for maintenance and sorting condition adjustment, when the dissimilar grain sorting section A on the wind sorting section B is moved upward as shown in Fig. 1, the brown rice flow passage E and the paddy rice flow passage D open in the middle, creating a gap C. Therefore, unhulled rice flows into the brown rice flow passage E through the gap C.

In addition, in the conventional system, the impact vibration of the hulling roll, the rotational vibration of the suction blower and the blower blower, the rotational vibration of the mixed rice conveyor, unripe rice conveyor, finished rice take-out conveyor, etc. are transmitted to the dissimilar grain sorting section. This had a considerable effect on the performance of the horizontal axis rotating tube.

The brown rice flow passage 46 is finally connected to the finished rice take-out gutter 29. 30 is finished rice removal gutter 29
This is a conveyor for removing finished rice installed horizontally on the bottom of the rice cooker.

FIG. 6 is a vertical sectional side view of the horizontally rotating barrel 24, and the horizontally rotating barrel 24 rotates to the left. Finished rice catcher 26
A finished rice control valve 32 is installed on the rotation rising side 31 of the machine. The lower end of the regulating valve 32 is fixed to a shaft 33, and the angle of the regulating valve 32 is adjusted by rotating the shaft 33.

Below the hulling section 1 side of the finished rice receiving trough 26, there is a first
As shown in the figure, an intermediate shelf 34 and a mixed rice collection gutter 35 are arranged side by side in the front and back direction. A return shelf 36 is provided below the mixed rice recovery gutter 35, and sensors 37 and 38 are installed at regular intervals on the bottom surface of the return shelf 36, as shown in FIG.
Install.

The sensor 37 is activated when the layer 39 of mixed rice formed in the horizontal shaft rotating cylinder 24 reaches a certain thickness or less and cannot be reached, and the sensor 38 is activated when the layer 39 reaches a certain thickness or more and comes into contact with the mixed rice layer 39. The sensors 37 and 38 rotate the motor 18 in the forward and reverse directions. 40 is a mixed rice conveyor.

As shown in FIG. 6, a supply gutter 41 is installed in parallel on the descending side of the finished rice receiving gutter 26. A supply spiral 42 is provided on the bottom surface of the supply trough 41.

The discharge side (hulling section side) of the rotary cylinder 24 is completely opened so as to serve as an unhulled rice discharge port 43. The unhulled rice discharge port 43 faces onto an unhulled rice flow passage 44 formed in a part of the cushion material 12. The paddy rice flow passage 44 is formed by making a part of the horizontal cushion material 12 protrude both upward and downward.

The end of the cushion material 12 on the side of the rice hulling part 1 is bent vertically upward to form a raised part 45. The rising portion 45 also serves as a part of the cylindrical paddy rice flow passage 44. The rising portion 45 is brought into contact with a side wall of a brown rice flow passage 46 provided on the case 11 side.

The lower end of the paddy rice flow passage 46 is connected to the return thrower 5.
1, and the upper end of the return thrower 51 is connected to the tensioning hopper 2.

A communication thrower 47 is attached to the discharge side of the mixed rice conveyor 6, and the upper end of the communication throat 47 opens into a supply hopper 48 of the dissimilar grain sorting section 10. The hopper 48 supplies grain to the feed trough 41. 4
9 is a falling tube formed in the supply gutter 41, 50 is a current plate, and 52 is a finished rice thrower.

(effect) Next, we will discuss the effect.

When the unhulled rice is supplied to the hopper 2, it is hulled between the hulling rolls 3, 3 and falls into the wind sorting section 4, the rice husks are wind washed, and the mixed rice falls onto the mixed rice receiving trough 8. The immature rice falls onto the immature rice receiving trough 9.

The mixed rice of paddy and brown rice that has fallen onto the mixed rice receiving trough 8 is conveyed horizontally by the mixed rice conveyor 6 and flows into the connecting throat 47, which is then raised and sent to the supply hopper 48.
is supplied to

Since the hopper 48 is open above the supply gutter 41, the water flows into the feed gutter 41, is transported horizontally to the falling tube 49 at the end by the supply spiral 42 in the feed gutter 41, and is fed down into the horizontal shaft rotating tube 24. Ru.

Since the horizontal shaft rotating cylinder 24 is rotating counterclockwise in FIG. 6, the mixed rice becomes a layer 39 as it rotates and is shifted toward the rotation rising side 31.

Since the lower layer of the layer 39 is a brown rice layer due to its specific gravity, a large amount of brown rice fits into the pot hole 25, rises as the horizontal shaft rotating cylinder 24 rotates, and is taken out to the finished rice receiving trough 26. In the finished rice receiving trough 26, the finished rice is conveyed horizontally to the outlet 28 side by the finished rice conveyor 27, and then transferred to the outlet 28.
8, flows down through the brown rice flow path 46 to the finished rice take-out gutter 29, and is taken out via the finished rice take-out conveyor 30 and the finished rice thrower 52.

The upper layer of the layer 39 is unhulled rice, and the middle layer is a mixed rice of unhulled rice and brown rice.
5, so it does not rise much and falls into the mixed rice recovery gutter 35 at a low position, and is returned to the drop tube 49 side by the mixed rice conveyor 40 provided in the mixed rice recovery gutter 35. , undergo re-screening.

Then, only the unhulled rice remains in the horizontal shaft rotating cylinder 24, which flows down from the unhulled rice discharge port 43 on the discharge side of the horizontal shaft rotating cylinder 24 into the unhulled rice flow passage 44, and is pulled up by the return thrower 51. The rice is returned to the hopper 2 and hulled again.

However, if the amount of grains supplied in the horizontal axis rotating cylinder 24 decreases, or the horizontal axis rotating cylinder 24
The rotation speed of the product changes or the quality of the product changes.
The grain layer 39 on the lower surface of the reduction shelf 36 below the mixed rice collection gutter 35 may become too thin (a phenomenon in which the rice is not discharged freshly). Then, the sensor 37 detects this, energizes the motor 18 to rotate the shaft 15 in the forward direction, moves the screw tubes 21 and 22 in the direction of spreading, moves the arms 19 and 20 in the vertical direction, and then rotates the shaft 15 in the forward direction. The falling cylinder 49 side of the shaft rotating cylinder 24 is moved upward. This upward movement causes the grain to be actively transferred to the outlet 28 side, increasing the thickness of the grain layer 39 on the discharge side and increasing the discharge amount.

In addition, if the amount of grains to be supplied increases, or the rotation speed of the horizontal shaft rotating cylinder 24 changes, or depending on the quality, the reduction shelf 3 below the mixed rice collection gutter 35
The grain layer 39 on the lower surface of the grain layer 6 may become too thick (a phenomenon in which the amount of discharge is too large). Then sensor 3
8 detects this and energizes the motor 18 to rotate the shaft 15.
is rotated in the opposite direction, the threaded tubes 21 and 22 are moved in the narrowing direction, the arms 19 and 20 are tilted, and the falling tube 49 side of the horizontally rotating tube 24 is moved downward. This downward movement weakens the movement of the grain toward the outlet 28 side, reduces the thickness of the grain layer 39 on the discharge side, and reduces the discharge amount.

By automatically adjusting the inclination of the horizontal shaft rotating cylinder 24 in this way, the entire case 11 rotates around the shaft 13, and the brown rice flowing passage 46 on the wind selection section 4 side and the brown rice flowing passage on the case 11 side are rotated. A gap is created between 46 and
The unhulled rice in the unhulled rice flow passage 44 tends to flow into the brown rice flow passage 46, but the present invention is provided with a rising portion 45 that rises at the boundary between the brown rice flow passage 46 and the unhulled rice flow passage 44. The upper part 45 prevents unhulled rice from getting mixed into the finished rice.

In addition, during the above-mentioned operation, in the conventional method, the hulling impact vibration of the hulling rolls 3, 3, the rotational vibration of the suction blower 5 and the ventilation blower 5', the mixing rice conveyor 6,
The rotational vibrations of the unripe rice conveyor 7, the finished rice take-out conveyor 30, etc. are transmitted to the different grain sorting section 10, and have a considerable effect on the performance of the horizontal shaft rotating cylinder 24. Since the cushion material 12 is interposed between the horizontal shaft rotary cylinder 24 and the horizontal shaft rotary cylinder 24, vibrations are transmitted to the horizontal shaft rotating cylinder 24 to a small extent, so that the performance is not impaired.

(Effects) In the known hulling device, since the brown rice flow passage and the unhulled rice flow passage are arranged close to each other, the unhulled rice flowing down the unhulled rice flow passage may get mixed into the brown rice flow passage. That is, when the wind selection section is provided below the hulling section and the different grain sorting section,
Since the structure connects the brown rice flow passage and the unhulled rice flow passage of the foreign grain sorting part to the brown rice flow passage and the unhulled rice flow passage of the wind sorting part, the positions of the foreign grain sorting part and the wind sorting part can be shifted even slightly during assembly. Then, the unhulled rice flow path overlaps with the brown rice flow path, and unhulled rice is mixed in. Also, for maintenance and sorting condition adjustment, when the dissimilar grain sorting section A on the wind sorting section B is moved upward as shown in Fig. 1, the brown rice flow passage E and the paddy rice flow passage D open in the middle, creating a gap C. Therefore, unhulled rice flows into the brown rice flow passage E through the gap C. Also,
In the conventional system, the impact vibration of the hulling roll, the rotational vibration of the suction blower and the blower blower, the rotational vibration of the mixed rice conveyor, immature rice conveyor, finished rice removal conveyor, etc. are transmitted to the dissimilar grain sorting section, and the horizontal axis This had a considerable effect on the performance of the rotating cylinder.

However, the present invention provides a hulling section 1, a dissimilar grain sorting section 10 having a horizontal axis rotating cylinder 24 in which numerous pot holes 25 are formed, and a dissimilar grain sorting section 10 located below the hulling section 1 and the dissimilar grain sorting section 10. A brown rice flow passage 46 and a unhulled rice flow passage 44 are disposed in close proximity to each other between the dissimilar grain sorting section 10 and the wind selection section 4. 4 and the dissimilar grain sorting section 10 is a cushion material 1.
2, and the cushion material 12 includes:
Since the rotary grain selection type hulling device is provided with a rising part 45 that rises at the boundary between the brown rice flow passage 46 and the unhulled rice flow passage 44, the extraction material 12 allows the hulling part 1 and the wind selection Since the vibration of the section 4 is not transmitted to the horizontal axis rotating cylinder 24, the performance of the horizontal axis rotating cylinder 24 is not deteriorated.

(b) Even if the different grain sorting section 10 is moved up and down for sorting adjustment or maintenance, unhulled rice is not mixed in the brown rice flow path 46.

Furthermore, since the rising part 45 has a cylindrical shape and is a rotary grain sorting type hulling device that also serves as the unhulled rice flow passage 44, the structure is simplified.

This effect is achieved.
