Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a rotary sorting unit in which a receiving gutter is inserted into a sorting cylinder which is rotatably hung horizontally and has a large number of depressions formed in its inner circumferential surface. The vertical position of the control valve that guides the mixed grains of brown rice and paddy into the receiving trough is changed according to the thickness of the fluidized bed, that is, the height of the upper surface of the mixed grain, and if the height of the fluidized bed exceeds a set value, it is transferred to the de-aging roll. This invention relates to a rotary sorting unit m machine equipped with a supply sorting automatic adjustment device that automatically reduces the amount of rice to be supplied.

The sorting action in this rotary sorting section is carried out by scooping out the recesses in the process of gradually moving the mixed grains from one end of the rotating sorting cylinder to the other end. Maintaining the thickness of the fluidized bed of the mixed grains flowing through the body within a predetermined preferred value range is the reason for achieving good screening purity and achieving high efficiency.

In other words, if the thickness of the fluidized bed is thinner than the set value, the scooping effect of the hollow will be weak, but the paddy will not float on the fluidized bed but will flow mixed with the brown rice, so it will not be able to scoop up the rice into the hollow. It's easy to get stuck in it, and it ends up being scooped up to a high place and falling in a parabola.

Therefore, the sensor detects the thin state of the fluidized bed and changes the control valve to the upper position.

In addition, if the fluidized bed becomes thicker than the upper limit of the set value, the scooping action by the depressions becomes strong and the paddy floats above the brown rice and is scooped up to a high level even though it is flowing, so in this case, the paddy is removed from the roll. The present invention aims to create a highly efficient rotary sorting and hulling machine that can reduce the amount of rice supplied to bring it close to the set value, thereby achieving good sorting purity without requiring any manual labor.

The present invention will be described below with reference to the drawings, but first, an overview of the rotary sorting and hulling machine itself will be explained. is a rotary sorting section, the desilicating section <a> consists of a paddy tank (1), a pair of desiliconizing rolls (2), etc., and the wind sorting section (b) is mainly a desiliconizing section <a> at the front part.

4) (5) and (6) are installed diagonally in sequence, and the lower end of the grain board (6) looks forward into the main wind selection path (7) that slopes upward. It communicates with the intake port (9) that opens on the rear wall through the brown rice wind selection path (8), which will be described later, and the upper part is equipped with a suction machine (
10). (11) is the first material transfer trough installed horizontally at the bottom of the main wind channel (7), and (]2) is the wind channel.

At the rear, there is a brown rice flow plate (13) that receives the brown rice from the rotary sorting section (C), and below the brown rice flow plate (13), the brown rice sorting path (8) is formed, and (14) is a waste rice removal path.

Next, the rotary sorting section (C) will be described.

(15) is a sorting cylinder with a number of depressions (16) formed on its inner circumferential surface, and both front and rear ends are horizontally mounted so as to be rotatable by driving wheels (17) and (18), respectively. In this case, the rotation axis of the sorting cylinder (work 5) is installed in the front-rear direction, and the supply side (X) of the mixed grains is placed backwards and the discharge side (Y)
This discharge side (Y) is adjacent to the desensitization part (, ) with the front side facing forward.

(19) and (20) are located on the supply side (
A mixed grain transfer gutter and a brown rice receiving gutter are installed horizontally from X) to the discharge side (Y), and screw conveyors (21) and (22) are installed inside these gutter (19) and (20), respectively. The mixed grain transfer gutter (19) has a drop opening (23) that transports the mixed grains from the discharge side (Y) to the supply side (X) and drops them from the supply side (X), and the brown rice receiving gutter ( 20
) is configured to bend and transfer from the supply side (X) to the discharge side (Y).

(24) and (25) are adjustment plates whose base ends are pivoted to the grain receiving side of the mixed grain transfer gutter (19) and the brown rice receiver 1fI (20), respectively, so that the inclination angle can be changed and the vertical position can be changed freely. .

A plurality of flip-up plates (26) are equally distributed on the inner peripheral surface of the sorting cylinder (15) at the discharge side (Y) end.
27) is joined to the outside of this jump plate (26) and is connected to the discharge side (
(28) is an annular blocking plate that prevents the grains that have reached the paddy tank (Y) from spilling out; 1) It communicates with the reduction port (29) opened on the rear wall.

Furthermore, (30) is a thrower for lifting up the mixed grains after demelting and wind sorting, the lower part of which is connected to the above-mentioned flavor transfer gutter (11), and the upper part is connected to the destretching part (a) and the rotary sorting part (C). The space (P) formed below the paddy tank (1) is located adjacent to the front wall (C).
The opening at the upper end passes through this front wall (Ca) and looks into the mixed grain transfer trough (19).

The discharge side (Y) of the brown rice receiving trough (2o) is the falling path (
31), and the lower part of this drop path (31) is connected to the brown rice flow plate (13) on one side and the grain flow plate (6) on the other side by means of a switching valve (32).

Incidentally, (33) is a transmission part that transmits the power for taking out the gearboxes in the a'f$ part (a) to the rotation sorting part (C).

Therefore, the paddy that is sequentially supplied from the paddy tank (1) is dropped by a pair of demelting rolls (2) and wind-selected in the main wind selection channel (7), and the mixed grains of brown rice and paddy are transferred to the first place. Direct mixed grain transfer from the gutter (11) by the thrower (30) to the gutter (19)
It enters inside and is transferred towards the supply side (X) and falls into the drop port (23).
The person falls onto the inner peripheral surface of the sorting cylinder (15). In addition, dust such as rice husks is discharged from the suction machine (10) from the wind selection path (12) to the outside of the machine, and the mixed grains that have fallen onto the inner peripheral surface of the sorting cylinder (15) are removed from the second Due to the scooping action of the recess (16) which rotates in the direction shown by the arrow (A) in Figures 1 and 3, the liquid is sorted while the flow gradually moves in the direction shown by the arrow (B) in Figure 1. .

In other words, brown rice, which is smaller in size than paddy, is difficult to escape from (1G) and is scooped up to the highest position. Brown rice and some paddy that cannot be scooped are transferred to the mixed grain transfer gutter (19)
It falls in, merges with new mixed grains, and becomes hollow again (16)
After repeating the sorting action, the paddy that cannot be scooped up moves to the discharge side (Y), is lifted up by the jump plate (26), falls into the reduction gutter (28), passes through the reduction port (29), and is sent to the paddy tank. It is reduced to (1) and desexed again.

In addition, the brown rice that has flowed into the brown rice receiving trough (20) is placed on the discharge side (Y
), the brown rice is transferred to a drop path (31), enters the brown rice original board (13), and then enters the brown rice wind selection path (8), where it is taken out to a suitable location outside the machine after wind selection.

Next, to explain the main part of the present invention, (34) is a detection sensor, which is located on the upper side in the rotating direction inside the sorting cylinder (15) indicated by the arrow (A) as shown in FIGS. 3 and 7. On the grain receiving side and below the mixed grain transfer gutter (°19), the upper end is fixed to the pivot (35) on the part closer to the supply side (X) and swings in the rotation direction of the sorting cylinder (15). It is attached freely and the lower part is slightly bent to form a sorting cylinder (15) as shown in Figure 7.
A contact surface (34a) is formed which comes into contact with the upper surface of the fluidized bed (c) which deviates from its inner peripheral surface and flows in a precipitating state.

Note that this fluidized bed (c) indicates the lower limit of the set value of the height of the fluidized bed.

(36) is an arm frame that projects diagonally downward from the rear end of this pivot (35), and (37) has two parts in a diamond shape, the lower part extends downward, and the middle part is the brown rice receiving trough (37). A control plate rotatably fitted onto the support shaft (25a) of an adjustment plate (25) whose base end is pivotally connected to the grain receiving side of the control plate (37).
) Several locking holes (37a) are drilled at equal intervals on an arc centered on the support shaft (25a), and the base end is connected to the arm frame (3
It is connected to the lower end of 6) by the link (38).

(39) has its proximal end fixed to the support shaft (25a) on the outside of the control plate (37), and its second end is fixed to the locking hole (37a).
) is an operation stick that can be engaged and disengaged from each other.

In addition, (40) is an ammunition whose lower part than the middle part of the said control board (37) can be indexed to the pivot (35).

Further, a protrusion (37b) is provided on the right side edge of the control plate (37), and an adjustment tool (41) is provided on this protrusion (37b).
The elongated hole (41a) is freely fitted into the elongated hole (41a), and the elongated hole (41a) is fitted freely.
The upwardly extending portion (1b) of the supply plate (1a) that adjusts the width and narrowness of the paddy supply path formed between the paddy tank (1) and the desiliconization roll (2) in a) and the adjustment tool (41) ) are connected to each other by a wire (42).

Therefore, when starting the operation of this rotary sorting rice huller mentioned above, in advance, the sorting cylinder 15) is placed on the upper surface of the fluidized bed (c) which is deflected and flows on the inner circumferential surface of the sorting cylinder (15), and the contact surface of the sensing sensor (34) is 3
4a) is in sliding contact with the control plate (37), adjust the inclination angle, that is, the vertical position, of the adjustment plate (25) using the operation stick (
The protrusion (37b) is engaged with an appropriate locking hole (37a) by rotation of the adjusting tool 41) and the long notch (41a)
) so that it is in an idle state.

Now, if the mixed grains lifted by the thrower (30) and supplied into the sorting tube (15) increase, the sorting tube (15) increases.
15) The flow N (c) flowing on the inner circumferential surface becomes bulky and gradually exhibits a large precipitation state, forming the fluidized bed shown in (d).

Then, the contact surface (34a) of the sensing sensor (34) is pushed by the upper surface of the flow N (d) and retreats against the bullet ta (40), and at the same time, the control plate (37) is moved through the link (38). and rotates around the support shaft (25a) 7 to the grain receiving side.
Due to the engagement of the locking hole (37a) and the upper end of the operating rod (39), the adjustment Fi (25) is also tilted to the state shown in the imaginary line in FIG. 7, and the protrusion (37b) is elongated (4ia
), and the height of the fluidized bed reaches the set value of -1-.

Therefore, if the fluidized bed becomes higher than this, the protrusion 37b) in the state shown below is #I! If the joint (41) is indexed upward and the extension part (1b) of the supply plate (1a) is rotated via the wire (42), the supply plate (la) is removed and the stripping part roll ( 2) The amount of mixed grains supplied to the sorting cylinder 15) is adjusted by narrowing the paddy supply path.

Conversely, if the amount of mixed grains supplied into the sorting cylinder (15) decreases, contrary to the above, the fluidized bed (
c) becomes thinner and the sensing sensor (34) and control board (37) become thinner.
The L adjustment plate (25) is operated in the opposite direction, and the adjustment plate (25) is displaced upward to prevent paddy from being introduced into the brown rice receiving trough (20).

As described above, the present invention provides a rotary sorting rice huller equipped with a rotary sorting section formed by inserting a receiving gutter into a sorting cylinder which is rotatably hung horizontally and has a large number of depressions formed in its inner circumferential surface. In the machine, a control valve that can change the vertical position is provided on the grain receiving side of the receiving trough, and the mixed grains flowing in the sorting cylinder are deviated in the direction of rotation of the sorting cylinder. A sensor is installed to detect the height of the layer, and the position of the control valve 7F is changed and adjusted via this sensor, and if the height of the fluidized bed exceeds the upper limit of the set value, the flow to the desiliconization section is Since the paddy supply amount is configured to be automatically reduced, adjustment is made on the grain receiving side of the receiving trough according to the height of the fluidized bed of mixed grains that flow and transfer on the periphery of the rotating sorting cylinder. Without displacing the plate to directly guide the paddy into the receiving trough, and in addition, when the height of the fluidized bed exceeds the upper limit of the set value, the amount of paddy supplied for desilication is reduced, and the above-mentioned fluidized bed is We have seen the emergence of a labor-saving rotary sorting huller that automatically guides the height of rice grains within a set range, thereby ensuring good sorting purity and high efficiency.
