Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is designed to sort brown rice from mixed rice after hulling by rotating a plurality of disks each having a large number of recesses on the surface. The present invention relates to a rice hulling sorting device.

[Conventional technology]

In the sorting cell, a rotating shaft is driven to rotate with a substantially horizontal position, and a plurality of donut-shaped disks each having a large number of recesses formed on one or both sides are provided at appropriate intervals in the axial direction, while the above-mentioned The sorting cell is provided with a supply section for a mixture of paddy and brown rice at one end in the axial direction, and a paddy discharge section at the other end.
Furthermore, a disc rotating type sorting mechanism in which a brown rice receiving trough is provided between each of the discs has been proposed in Japanese Patent Laid-Open No. 136688/1988 as a prior art.

In addition, among the prior art as a culm removal sorting device comprising a culm removal mechanism for removing culms and a cylindrical rotary sorting mechanism, Japanese Patent Application Laid-Open No. 59-906T7 discloses that a culm removal mechanism is provided above the culm removal mechanism. It is disclosed that the paddy supply hopper is disposed on one side of the rotary sorting mechanism, and the rotating shaft of the rotary sorting mechanism and the culling roll shaft in the culling mechanism are disposed at right angles to each other. ing.

[Problem that the invention seeks to solve]

Therefore, paddy can only be supplied to the paddy supply hopper from one direction of the sorting device, and increasing the size of the paddy supply hopper has the disadvantage that the entire device becomes bulky.

This problem cannot be easily solved even if a disc rotating sorting mechanism is provided in place of the cylindrical rotating sorting mechanism.

Further, if the desiliconizing roll shaft and the rotating shaft of the desiliconizing mechanism are arranged orthogonally to each other, there is a problem that the power transmission system for both becomes complicated.

The present invention aims to solve this problem.

[Means to solve the problem]

In order to achieve this object, the present invention provides a method in which a disk sorting mechanism is provided in the huller sorting and paddy supply hopper at an eccentric position in a plan view, and the disk sorting mechanism is disposed within the sorting cell. A horizontal rotating shaft is provided with a plurality of disks each having a plurality of recesses formed on its surface at appropriate intervals, and the rotating shaft and a culling roll shaft in the culling mechanism are connected to each other. They are arranged parallel to each other.

[Action/effect of the invention]

As described above, in the present invention, since the disc sorting mechanism is provided in the paddy supply hopper located above the desiliconization mechanism, the paddy supply hopper is arranged in parallel with the paddy supply hopper and the disc sorting mechanism. Even if the shape in plan view is made large, the device does not become bulky, and the entire device can be downsized.

Furthermore, since the disk sorting mechanism is provided eccentrically in the paddy supply hopper in plan view, a layout can be created in which at least two or three sides of the upper surface side edge of the paddy supply hopper face the outside of the apparatus. Therefore, paddy can be supplied from two or three sides of the device, and even if paddy or the like leaks from the disk sorting mechanism, it is received by the paddy supply hopper and there is no risk of it leaking out of the device.

Furthermore, since the rotating shaft of the disk sorting mechanism and the desiliconizing roll axis of the desiliconizing mechanism are arranged in parallel, there is also the effect that the power transmission mechanism for both can be simplified.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. A hulling and sorting device 1 includes a hulling mechanism 3, a wind selection section 4, and a hulling mechanism in a box-shaped machine frame 2 that is vertically long and approximately rectangular in plan view. A paddy supply hopper 6 having a rectangular shape in plan view is disposed at an upper position of the rice hopper 3, and a disk sorting mechanism 5 is located inside the paddy supply hopper 6.

The hulling mechanism 3 consists of a pair of left and right desiliconizing rolls 7, etc., and the desiliconizing roll shaft 8 is rotationally driven by a motor 10 via a belt 9.

The wind sorting unit 4 is located at the lower part of the culling mechanism 3, and separates the fallen rice after culling into chaff and mixed rice (a mixture of paddy and brown rice), and transfers the mixed rice to the disc sorting mechanism 5. It is constructed of a grain board 11, a mixed rice receiving trough 13 with a spiral conveyor 12, a suction dust exhaust fan 14, etc., and one end of the mixed rice receiving trough 13 has a disc sorter for the mixed rice. A mixed rice thrower 15 for feeding to the mechanism 5 is connected, and the mixed rice thrower 15 and the suction dust removal fan 14 are rotationally driven by a motor 10.

The disk sorting mechanism 5 places the sorting cell 16, which has at least a cylindrical lower half, in a so-called eccentric position within the paddy supply hopper 6, which is rectangular in plan view, toward one side in plan view. The sorting cell 1
The upper part of the paddy hopper 6 projects upward from the paddy supply hopper 6. The sorting cell 16 has a side plate 16 at one end in the axial direction.
A supply hole 17 is provided at the side plate 16b at the other end, and a discharge hole 1 is provided at the side plate 16b at the other end.
8 are bored respectively, and the supply hole 17 is opened at the tip of the mixed rice thrower 15, while the discharge hole 18 is
A reflux chute 20 for refluxing the paddy discharged from the discharge hole 18 into the paddy supply hopper 6 is connected thereto.

Furthermore, a rice residue discharge valve 21 that opens into the paddy supply hopper 6 is provided on the bottom surface of the sorting cell 16 so as to be openable and closable.

Inside the sorting cell 16, a rotating shaft 22 that is rotated at an appropriate speed by the motor 10 is supported in parallel with the desiliconizing roll shaft 8. A donut-shaped disk 2 in which a number of recesses 23 are engraved with dimensions that allow the rice to fit into it but not the rice grains.
A plurality of discs 4 are provided at appropriate intervals in the axial direction (however, the drawing shows a case where recesses 23 are carved on both sides of the disc 24).

In addition, each of the multiple recesses 23 in each disk 24
is an elliptical shape in which the length in the circumferential direction of the disk 24 is larger than the width in the radial direction, and the width in the radial direction is smaller than the length of brown rice. On the other hand, among both the left and right inner surfaces in the longitudinal direction of each recess 23, the inner surface located on the front side with respect to the disk rotation direction is set at an appropriate angle (
For example, the length dimension from the intersection of this inclined inner surface and the bottom surface of the recess to the other inner surface is approximately equal to the length dimension of brown rice, and the length dimension is approximately equal to the length dimension of brown rice. The dimensions are set to be intermediate between the length of brown rice and the length of paddy, and the depth of the recess is set to be approximately equal to the diameter of brown rice.

Brown rice receiving troughs 25 are inserted in an inclined manner in the upper portions between the disks 24 and the upper portions between the disks 24 and the side plates 16a, 16b of the sorting cell 16.
5 is a brown rice chute 27 through the upper surface of the brown rice flow down plate 26.
The finished rice thrower 2 is connected to the brown rice sorting section 28 and is connected to the finishing rice gutter with a conveyor coaxial with the spiral conveyor 12.
It is configured so that it can be discharged outside the device 1 via 9.

Incidentally, reference numeral 30 is an integral cover that covers the upper surface of the paddy supply hopper 6 in a manner that it can be opened and closed, and the cover body 30 may be divided into two or three parts.

Therefore, when paddy is fed into the paddy supply popper 6 during the hulling and sorting work, the dropped rice that has been dehulled by the hulling mechanism 3 is removed so that the rice husks are sucked into the suction dust exhaust fan 14 in the wind selection section 4. The mixed rice, from which the rice husks have been removed by wind sorting, enters the mixed rice receiving trough 13 and is transferred to the mixed rice thrower 15.
The liquid is then supplied into the sorting cell 16 through its supply hole 17.

The mixed rice thus supplied into the sorting cell 16 is
As the disks 24 rotate in the areas between the disks 24, they are raised to a height as shown by the dashed line arrow A in FIG. 1, and then flowed as if falling.
It is transferred toward the discharge hole 18.

During this flow, the brown rice in the mixed rice is 2 discs each!
! Each brown rice receiving gutter 2 falls by falling from the recess 23 after being lifted up to a high position by fitting into the recess 23 in the
Selected to be in the top 5.

The brown rice that has entered each brown rice receiving trough 25 in this way is subjected to finishing sorting in the brown rice sorting section 28 and then taken out of the machine from the finished rice thrower 29, while the inside of the sorting cell 16 is passed through the discharge hole 18. The mixed rice that moves in the direction of
By rotating each disc 24, brown rice is removed so as to enter each brown rice receiving trough 25, so that the ratio of paddy increases as it approaches the discharge hole 18, and the paddy is transferred from the discharge hole 18 into the paddy supply hole 6. It flows out and the desiliconization action is performed again.

As in the present invention, the disc sorting mechanism 5 is arranged in the paddy supply hopper 6 so as to be eccentric in plan view, so if the cover unit 3o is removed, the upper opening of the paddy supply hopper 6 will be opened to the disc. 2nd side to 3rd side of sorting mechanism 5
It can be opened to surround the side, and paddy can be freely supplied from the 2nd or 3rd side of the sorting device 1, improving work efficiency. On the other hand, when the remaining rice discharge valve 21 is opened after the work , the mixed rice can be easily collected into the paddy supply hopper 6.

Moreover, even if the planar view shape of the paddy supply hopper 6 is enlarged,
Since the disk sorting mechanism 5 is surrounded, the entire device is not bulky and the device can be made more compact compared to the case where the disk sorting mechanism 5 is arranged in parallel outside the paddy supply hopper 6. .

Furthermore, since the desiliconizing roll shaft 8 in the desiliconizing mechanism 3 and the rotating shaft 22 in the disk sorting mechanism 5 are arranged in parallel, the mechanism for transmitting power to both becomes simple.

If the discharge tube 31 at the upper end of the finished rice thrower 29 is configured to be rotatable left and right, the finished rice can be taken out to any desired position outside the machine.
