Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention is a machine body in which a plurality of selection disks each having a plurality of potholes formed on the side surface thereof are provided at intervals on a rotating shaft for horizontal installation. Wear
A brown rice gutter for receiving brown rice lifted up by a pot and picking it up at the side of this sorting disk is inserted obliquely and can be used for a disk type rotary sorting device for sorting mixed rice of brown rice and paddy.

(B) Conventional technology A disk-type rotary sorting device configured as described above for sorting a mixed rice of brown rice and paddy, wherein a paddle take-out outlet provided at the drain is opened on the side wall of the drain. The applicant of the present invention has already applied for Japanese Patent Application No. 61-230565.

By the way, the paddy outlet of this application has a height higher than the mounting position of the brown rice gutter to the body bottom plate, and is opened in the center of the upper body. Therefore, the mixed rice of brown rice and paddy supplied to the inside of the machine body is discharged while forming a fluidized bed that is swirled in a piled state due to the turning direction of each sorting disk being swung by the turning of each sorting disk. Although it moves to the wa, the mixed rice that the brown rice gutter wraps around and flows around the rice leaks between the brown rice gutter and the selection disk and becomes mixed with the brown rice that is picked up by the brown rice gutter. However, there is a drawback that the selection purity of is lowered. On top of that, the mixed rice forming the upper layer of the fluidized bed moves from the passage hole provided in the shaft of the selection disk to the discharge gutter, and the rice paddle skids without sufficient lifting action by the pot hole. Since it is discharged from the take-out port, brown rice is mixed in the paddy discharged from the paddy take-out port.

(C) Problems to be Solved by the Invention As described above, according to the configuration of the applicant previously filed, the height of the paddy outlet provided in the discharge pit is the bottom plate of the brown rice gutter of the applicant. The mixed rice that opens at the center of the aircraft at a position higher than the mounting position on the machine and forms a fluidized bed and turns back by the brown rice gutter is cut off between the brown rice gutter and the selection disk. There is a drawback that it mixes into brown rice,
Moreover, the mixed rice is discharged from the passage through which the shaft of the sorting disk is provided in the saw, slides sideways, and is discharged from the paddy take-out port. Since there is a problem that brown rice is mixed in the discharged paddy, the present invention solves these drawbacks and problems so as not to lower the selection purity of the selected brown rice. At the same time, it was invented for the purpose of improving the selection of the paddy discharged from the paddy take-out port.

(D) Means for Solving the Problems Therefore, according to the present invention, several sorting disks having a large number of potholes formed on the side surfaces are axially mounted at intervals on a horizontally rotating rotary shaft in the body. , A disc-type rotary sorting device that inserts brown rice gutters into the sides of this sorting disk and obliquely installs the mixed rice of brown rice and paddy to feed it and discharge it to the paddle while flowing and moving it toward the paddy In addition, in the one in which the drainage opening provided in the discharge gutter is opened to the side wall of the discharge gutter, the grain extraction outlet is connected to the brown rice gutter and to the bottom plate of the machine body of the brown rice gutter. It is provided below the mounting position.

(E) Action As a result, the mixed rice of brown rice and paddy that is supplied from the inside of the machine is diverted in the direction of rotation due to the rotation of each sorting disk and circulates in a piled state. While the discharge fluidizes and moves toward the wall while forming the fluidized bed, the potholes formed on the side surfaces of each sorting disk are lifted. Due to this lifting action, the brown rice is lifted up to a high position and falls into the brown rice receiving trough, is received and flowed out, and the paddy drops into the pot hole even during lifting and reaches the brown rice receiving trough. It is not lifted up and falls on the fluidized bed, and the discharge gradually shifts to the waste and is discharged from the paddy outlet.

In this case, the paddy outlet opening on the side wall of the discharge is provided below the position where the brown rice gutter is attached to the bottom plate of the machine, and the piled state of the fluidized bed does not become excessively large. The mixed rice that wraps back in the river moves to the drain without any leakage between the brown rice gutter and the selection disk, and the paddy outlet has an opening in the brown rice gutter and the drain grabs the rice. The mixed rice that has been transferred is subjected to the lifting action of the vase, and after being sufficiently sorted, only the paddy is discharged from the paddy outlet.

(F) Examples Hereinafter, the present invention will be specifically described with reference to the drawings.

The disk-type rotary sorting device shown in this example is shown in a form in which it is used for sorting mixed rice in a hulling machine, and therefore the schematic configuration of the entire hulling machine will be described.

As shown in FIG. 3, this huller has a disc type rotary sorting device (A) according to the present invention, a hulling section (2) and a wind selecting section (3) in a vertically long box-shaped machine body (1). ) Are arranged vertically, and the paddy hull part (2) is composed of a paddy tank (4), a pair of derolling rolls (5), etc., and is located in the middle part of the machine body (1). The section (3) is located below the paddy section (2), and the sludge after the removal is sorted into dust such as paddy grains and mixed rice of brown rice and paddy, and the mixed rice is rotated by the disc-type rotation. It is designed to be supplied to the sorting device (A), and is composed of a mixed rice horizontal trough (7) with a screw conveyor (6) and a sorting air passage (9) communicating with the suction dust exhaust fan (8). A mixed rice thrower (10) that lifts the mixed rice to the disk type rotary sorting device (A) is connected to one side of the mixed rice horizontal transfer trough (7).

The machine body (a) of the disk type rotary sorting apparatus (A) according to the present invention is formed by an upper part of the machine body (1) and an arc-shaped bottom plate (a1) integrally attached to the machine body (a). The upper side of the mixed rice thrower (10) is connected to the side wall (11) of the feed line to communicate with the inside of the machine body (a), and the side wall (12) of the discharge line has a paddy outlet (13). The paddle take-out port (13) is connected to the paddy tank (4) by the paddy-reduction cylinder (14).
It leads to inside.

In the machine body (a), several discs (17) having a large number of pot holes (16) formed on both sides of a pivot shaft (15) horizontally rotatably mounted are arranged at appropriate intervals. The disc is pivotally attached at a certain angle, and the direction of rotation of the sorting disk (17) which rotates in the direction of the arrow (a) is deviated to form a fluidized bed (P) which circulates in a piled state. Each brown rice gutter (18) is obliquely inserted into the side of each sorting disc (17) by welding the lower backside of the bottom gutter to the end face of the bottom plate (a1).

A plurality of passage holes (19) are formed in the shaft of the selection disk (17), and the paddy take-out port (13) is a brown rice gutter (1).
8) The brown rice gutter (18)
Is located lower than the attachment position (L) to the bottom plate (a1).

It is to be noted that (20) and (21) are pillar rods that are laid across from the side wall (11) to the side wall (12), and one support rod (20) has a lower end of each brown rice gutter (18). Is wound around, and the other supporting rod (21) restrains the lifting bed of the fluidized bed (P) that is about to rise and is inclined along the lifting bed of the fluidized bed (P). The upper end of the resistance plate (22) is wound around.

Further, (23) is a remaining rice discharge port that is opened over almost the entire width from the supply to the discharge of the bottom plate (a1), and the opening / closing plate (24) is attached to this remaining rice discharge port (23). Then, when the opening / closing plate (24) is opened, the remaining rice remaining on the bottom plate (a1) falls into the paddy tank (4), and (25) laterally transfers the selected brown rice. It is a brown rice extraction gutter that is taken out of the plane.

Therefore, the paddy supplied to the paddy tank (4) is slid off by the paddy section (2), and the sludge is wind-selected by the sorting wind passage (9) to remove paddy grains and rice gruel. , The removed mixed rice of brown rice and paddy flows into the mixed rice horizontal transfer gutter (7) and is lifted by the mixed rice thrower (10) to be the body (a) of the disk type rotary sorting device (A). Supplied within.

The supplied mixed rice is displaced in the bottom plate (a1) by the rotation of each selection disk (17) in the direction of the arrow (a) to form a fluidized bed (P). While the pot hole (16)
The brown rice in the mixed rice is lifted up to a high position by being lifted up by the, and falls to a brown rice receiving gutter (18), flows down, and is gathered in a brown rice removing gutter (25) to be taken out of the machine. Moreover, even if the paddy is placed in the pothole (16), the pothole (1
As it escapes from 6) and falls on the fluidized bed (P), the discharge is gradually transferred to the paddle and is returned from the paddy take-out port (13) to the paddy tank (4) through the paddy return tube (14). It is.

In this case, the unhulled outlet (13) that opens to the side wall (12) of the discharge is opened by the brown rice gutter (18) close to the swarf, and from the mounting position (L) of this brown rice gutter (18). Since the shape of the fluidized bed (P) that circulates in the bottom plate (a1) is not too large, the mixed rice that the brown rice gutter (18) folds back with a saw and circulates in the bottom plate (a1). It is higher than the upper end and does not leak from the brown rice gutter (18) and the selection disk (17) to fall into the brown rice removal gutter (25). Among them, the mixed rice forming the upper layer part of the fluidized bed (P) comes to pass through the passage hole (19) provided in the shaft of the sorting disk (17), and the mixed rice that has come to the side slips. In this state, the vat hole (16) is lifted up without reaching the paddy extraction port (13).

When the opening / closing plate (24) is opened at the end of the work, what remains in the bottom plate (a1) drops from the remaining rice discharge port (23) into the paddy tank (4).

(G) Effect of the Invention As described above, according to the present invention, a plurality of selection disks having a large number of potholes formed on the side surface are axially mounted at intervals on a horizontally rotating pivot shaft. Inserted brown rice gutters on the side of this sorting disk respectively, and installed a skewer to rotate the mixed rice of brown rice and paddy from the feed to the drain and flow to the paddle. At this point, in the one in which the paddy outlet provided in the drain is opened in the side wall of the drain, the paddle is the brown rice gutter and the mounting position of the brown rice gutter to the bottom plate of the machine body. Since it was constructed lower than the above, the rotation direction of the sorting disk was deviated to the alligator direction, and the shape of the fluidized bed that circulates in a piled state did not become excessive, and the brown rice gutter folded back at the wa The mixed rice that moves moves to the discharge without leakage between the brown rice gutter and the selection disk. Then, the sorting action is performed by raising the pot hole.

In addition, the unhulled exit is open to the brown rice gutter,
The mixed rice from which the discharge has shifted to the side does not reach the paddy outlet in a sideways state, and the rice is discharged from the paddy outlet after being sufficiently sorted by the lifting action of the pot hole.

As a result, in the present invention, the mixed rice forming a fluidized bed in the process of the selection action by raising the vase hole leaks from between the brown rice gutter and the selection disk and is not mixed into the selected brown rice. The mixed rice, which has not been reduced in the selection purity and whose discharge has been shifted, is sufficiently subjected to the selection action, and there is an advantage that brown rice is not mixed into the paddy from the paddy outlet.
