Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for inserting a receiving gutter into a sorting cylinder of a rotary sorting section, which has a number of depressions formed on its inner circumferential surface and is rotatably suspended horizontally. 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 of the flowing mixed grains of brown rice and paddy, that is, the height of its upper surface. This invention relates to a rotary sorting and hulling machine equipped with an automatic safety device for supply sorting that automatically stops the supply of paddy to the ball rolls.

The reason for the sorting action in this rotary sorting section is to keep the thickness of the fluidized bed within the predetermined preferred value range from beginning to end to achieve good sorting purity and high efficiency.

However, the conditions of the mixed grains often vary due to differences in product types, and the thickness of the fluidized bed can become thin or thick.

In other words, if this fluidized bed is thinner than the set value, the scooping effect by the depressions will be weak, but since the paddy does not float on the fluidized bed but flows mixed with the brown rice, it is easy to get stuck in the depressions and even reach a high level. It will be scooped up and fall in a parabola.

Therefore, in this case, the sensor detects the thin state of the fluidized bed and moves the control valve to the two-way position.

On the other hand, 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, and the purity of the sorting only decreases. This can also cause a clogging phenomenon inside the aircraft, making it impossible to operate.

In view of the above-mentioned points, the present invention provides a control valve that can freely change the vertical position on the receiving side of the receiving gutter, and a flow of mixed grains flowing in the sorting cylinder in a direction in which the sorting cylinder rotates. A sensor is installed to detect the height of the layer, and the vertical position of the control valve is changed and adjusted via this sensor, and if the height of the fluidized bed exceeds the upper limit of the set value, the paddy is transferred to the desiliconization roll. The purpose of this is to stop the supply to stabilize the purity of the sorting and ensure the safety of the hulling operation.

Hereinafter, the present invention will be described with reference to the drawings of the embodiments. First, the outline of the rotary sorting huller itself will be explained.

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 (15) is installed in the front-rear direction, and the supply side (X) of the mixed grains is arranged backwardly to the discharge side (Y).
This discharge side (Y) is adjacent to the desensitization part <a> 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 tif+ (i 9 ) is on the discharge side (
The mixed grains are transferred from Y) to the supply side (X), and the mixed grains are transferred from the supply side (
A drop port (23) is opened for dropping brown rice from the supply side (,
Y).

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

A plurality of jump plates (26) are equally distributed on the inner peripheral surface of the discharge side (Y) end of the sorting cylinder (15).

The discharge side (Y) of the brown rice receiving trough (20) is the falling path (
31), and the lower part of this falling path (31) is connected to the top of the brown rice flow plate (13) and the other to the grain flow plate (6') l by means of a switching valve (32). be.

Note that (33) is a transmission section that transmits the power taken out from the gear box of the desiliconization section (a) to the rotational sorting section (C).

Therefore, the paddy that is sequentially supplied from the paddy tank (1) is slid down by a pair of de-melting rolls (2) and wind-selected in the main wind selection channel (7), and the mixed grains of brown rice and paddy are sent to the first transfer channel. (11) directly enters the mixing anti-transfer gutter (19) by the thrower (30), is transferred toward the supply side (X), and is dropped from the drop port (23) onto the inner peripheral surface of the sorting cylinder (15). people

Relatives also sucked up dust such as rice husks from Kofu Senro (12).
The mixed grains discharged from the machine from a (10) and falling onto the inner circumferential surface of the sorting cylinder (15) are placed in a recess that rotates in the direction shown by the arrow (a) in Figures 2 and 3. By the scooping action of (16), the particles are sorted while the particles gradually flow in the direction shown by the arrow (b) in FIG.

In other words, brown rice, which is smaller in size than paddy, is difficult to escape from the depression (16) and is scooped up to the highest level.The brown rice forms a parabola and falls into the brown rice receiving trough (20), and cannot be scooped up to the highest level. Some of the paddy falls into the mixed grain transfer gutter (19), joins with new mixed grain, and repeats the sorting action by the pit (16), and the paddy that cannot be scooped is transferred to the discharge side (Y
) and is lifted up by the jump plate (26) and returned to the reduction gutter (
28), passes through the reduction port (29) and enters the paddy tank (1).
) and is re-desexed.

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 the drop path (31), enters the brown rice draft path (8) from the raw brown rice plate (13), and 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. The supply side (on the grain receiving side and below the mixed grain transfer gutter (19)
X) The upper end is fixed to the pivot (35) on the side part so that it can swing freely in the rotating direction of the sorting cylinder (15), and the lower part is slightly bent as shown in Fig. 7. The inner peripheral surface of the sorting cylinder (15) is deflected to form a contact surface (34a) that comes into contact with the upper surface of the fluidized bed (c) flowing in a descending 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 obliquely downward from the rear end of this pivot (35), and (37) has a diamond-shaped upper part, a lower part that extends downward, and a middle part that is connected to the brown rice receiving trough (2).
A control plate rotatably fitted to a support shaft (25a) of an adjustment plate (25) whose base end is pivotally connected to the grain receiving side of 0),
Several locking holes (37a) are protruded at equal intervals on an arc centered on the support shaft (25a) of the control plate (37), and the lower end is connected to the lower end of the arm frame (36). 38).

(39) has a proximal end fixed to the support shaft (25a) on the outside of the control plate (37), and an upper end fixed to the locking hole (39a).

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).
A paddy supply path (R) is formed between the paddy tank (1) and the desiliconization roll (2) in the removal rod part <a>. , this paddy supply route (R
) A slide-type opening/closing plate (1a) that connects or blocks the
is provided.

An engagement hole (16) is bored in one side of the opening/closing plate (1a) to open the paddy supply path (R) and maintain communication between the paddy tank (1) and the stripping roll (2). A protrusion (43) provided in the engagement hole (1'b) that can move upwardly from the gear box (42) is engaged with the engagement hole (1'b). This protrusion (43) and the adjustment tool (4I) are connected by a wire (44), and the other side of the opening/closing plate (1a) is always pulled backward by a spring (45).

Therefore, at the time of starting the connection of this rotary sorting huller mentioned above, the contact surface of the sensing sensor (34) 3
4a) is in sliding contact with the control plate (37).
9), the protrusion (37b) engages with the appropriate locking hole (37a) and is determined by the rotation of the adjusting tool (41).
Set it so that it is in a state of play.

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

At the same time, the contact surface (34a) of the sensing sensor (34) is pushed against the upper surface of the fluidized bed (d) and the bullet (40)
At the same time, the control plate (37) moves back against the

The contact plate (25) also tilts and becomes the state shown in the imaginary line in Figure 7, with the protrusion (37b) coming into contact with the upper edge of the elongated hole (41a) and the height of the fluidized bed reaching the upper limit of the set value. It is reached.

Therefore, if the fluidized bed becomes higher than this, the protrusion (37b) in the above state will index the adjusting tool (41) upward and retract the protrusion (43) via the wire (44). As a result, the engagement state between the projection (43) and the engagement hole (1b) is released, and the opening/closing plate (1) is released by the tensile force of the bullet (45).
a) slides backward to block the paddy supply path (R) and stop the supply of paddy to the desiliconization roll (2).

Conversely, if the amount of mixed grains fed 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 adjustment plate (25) is operated in reverse, and the adjustment plate (25) is displaced upward to prevent the 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 freely change the vertical position is provided on the grain receiving side of the receiving trough, and the height of the fluidized bed of the mixed flow flowing in the direction of rotation of the sorting cylinder 9 is adjusted in the sorting cylinder. A detection sensor is provided to detect the above, and the vertical position of the control valve is changed and adjusted via the detection sensor, and if the height of the fluidized bed exceeds the upper limit of the set value, the supply of paddy to the deprocessing rolls is stopped. Because of this structure, the adjustment plate provided on the grain receiving side of the receiving trough is displaced according to the height of the fluidized bed of mixed grains flowing on the circumferential surface of the rotating sorting cylinder, and the paddy is placed in the receiving trough. Moreover, when the height of the fluidized bed exceeds the set value, the supply of paddy to the desiliconizing roll in the desiliconizing section is stopped to stabilize the sorting purity and prevent clogging inside the machine. This led to the emergence of a rotary sorting huller that made rice hulling work safer and less labor-intensive.
