Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice hulling device. The main object of the present invention is to particularly devised the treatment of residual rice.

Another object of the present invention is to provide a much simpler structure than conventional rice hulling devices of the same type, thereby reducing the cost.

Therefore, to explain the prior art of the present invention, the conventional one is as shown in FIG.

In Figure 1, A is a supply hopper installed at a high position into which grain bags are lifted and the raw material, unhulled rice a, is put in; B is a hulling section installed at the bottom of supply hopper A; A pair of rubber rolls C and C are pivoted. A wind sorting section is provided at the bottom of the hulling section B, and the lightweight rice husks C are wind sorted in the wind sorting section, and the hulled brown rice and the unhusked rice A remaining after the hulling are mixed and placed on the side. It flows into the lower part of the elevator E for mixed rice and fried grains on the side. At the upper end of the elevator E, a tank F, commonly called an adjustment tank, is suspended by a spring, and the tank F moves downwards due to its weight when a large amount of mixed rice accumulates, and moves upwards when it becomes low, depending on the amount of mixed rice stored. The up and down movement of the oscillator, which moves up and down accordingly, opens and closes the valve at the outlet of the supply hopper A in conjunction with the wire supplied to the tank F. The mixed rice in the adjustment tank F is moved to the swing type sorting device G, where it is separated, and the unhulled rice a is returned to the supply hopper A by the thrower H, and the brown rice is flowed into the elevator ■ as finished rice. taken out. A part of the intermediate rice that cannot be separated flows into the lower end of the elevator 411H again and is recirculated.

The deficiencies of the prior art are as follows: (a) Since the intermediate rice is returned to the elevator and circulated, there may be an oversupply, and in order to prevent this, a regulating tank F suspended by a spring is required. , the structure becomes more complex and the height increases.

However, measures for distributing the multi-stage sorting plates of the swing-type sorting device G just before the end of work have not been sufficiently taken.

That is the point.

The present invention has improved this point, and includes a wind-selecting section for wind-selecting the hulled material produced in the hulling section at the lower part or side of the hulling section, and a wind-selecting section located near the wind-selecting section. A multi-stage sorting section is provided for separating and sorting the mixed rice obtained by sorting, and the supply section of the multi-stage sorting section includes a distributing device that evenly supplies mixed rice to each stage of sorting plates. , forming a flow path that supplies mixed rice not only to the top one sheet but only to the top two to three sheets,
When the amount of mixed rice decreases, the rice is sorted using only two or three upper sorting plates. This is a hulling device having a structure in which a brown rice outlet is formed on one of the left and right sides and an unhulled rice outlet is formed on the other side, and there is no intermediate rice outlet.

To explain the overall structure using the overall schematic diagram of the newly developed invention shown in Fig. 2, l is a lift for feeding unhulled rice a, 2 is a hulling section, 3 is a wind sorting section, and 4 is a swing type sorter. device, 5

A dynamic sorting device 4 is provided. Therefore, when the rubber roll is 3 inches, it is about 3 to 4 pieces, and when the rubber roll is 10 inches, it is about 9 to 1 sheets.
It will be multi-stage with about O pieces. The outer frame 7 of the wind selection section 3 is placed on the upper part of the outer frame 6.

A rice hulling part 2 is placed on the upper part of one side of the outer frame 7.

A supply tank 8 is attached to the upper part of the rice hulling section 2.

Reference numeral 9 denotes a connecting tube, 10 a control valve, and a control plate 11 is rotatably attached to the lower part thereof with a shaft 12. 13 is an adjustment screw, 14
15 is a feeding roll, and 15 is an inclined plate 15. The tip of the inclined plate 15 faces the middle of the rubber rolls 16 and 17.

One rubber roll 16, 17 is provided diagonally above and below.

A diffuser 19 is provided on the discharge side 18 of the rubber rolls 16,17. The diffuser 19 is shaped like a square gutter.

The hulling section 2 is formed to have a width 20 that accommodates the rubber rolls 16 and 17, and is narrower than the width 21 of the wind selection section 111 of the wind selection section 3.

The left and right walls 22 and 23 of the hulling section 2 are respectively cut out to connect the diffusion tubes 24 and 25. The object that collides with the diffuser 19 jumps forward over the front rising edge 26 of the diffuser 19, collides with the reflector 27, and when reflected back, the diffuser 2
It will be fully diffused within 4.25 days.

The wind selection section 111 of the wind selection section 3 provided in the outer frame 7 has an inclined guide plate 28.29 that receives the grains reflected from the reflecting plate 27 and falls, and is located below the inclined guide plate 28.29. A cross-flow wind turbine 30 is mounted on a shaft 31. 32 is an inlet of the cross-flow windmill 30 formed in the wind selection section 111. Both of the inclined guide plates 28 and 29 are formed with a gentle slope. The grains on the inclined guide plates 28 and 29 flow due to the slight vibration of the wind selection section 111 and are supplied to the wind selection chamber 33 at the bottom.

Reference numeral 33 designates a wind selection chamber 33, in which a suction path 34 for the rice husks C is formed in the upper part of the wind selection chamber 33, and the suction path 34 is connected to a blower 35.

The lower part of the wind selection chamber 33 is in the direction of the width 21 (see Figure 10 A! IQ
), forming a hopper 36 that is open to the hopper 36
One of the valves is an on-off valve 38 whose upper end is fixed by a shaft 37.

The hopper is divided into two, front and back, and one hopper 36 serves as a passageway leading to the distribution device 87 that leads to the sorting plates of each stage, and the other feeds only to the upper two to three stages of the 10 stages of sorting plates, for example.
(not only the top sorting plate) forming a passage 114,
Install the switching valve 113.

An arm 39 is made to protrude laterally from the shaft 37.
The lower end of the spring 40 is connected to the lower end of the spring 40. 41 is an adjustment screw connected to the upper end of the spring 40, and 42 is an adjustment nut screwed onto the adjustment screw 41.

An eccentric cam 43 is attached to the shaft 31, and the other end of a connecting rod 44, one end of which is fixed to the outer ring 112 of the eccentric cam 43, is fixed to the side wall of the wind selection section lll. The air selection section ill is a container that vibrates slightly, and is suspended from the outer frame 7 by diagonal rods 45 and 46. Therefore, when the shaft 31 rotates at high speed, the wind selection section 111 of the wind selection section 3 vibrates violently in the direction of the arrow via the eccentric cam 43, the outer ring 112, and the connecting rod 44.

Fig. 5B shows the outer ring 11 without using the connecting rod 44 and the diagonal rod 46.
2 is directly fixed to the side wall of the wind selection section 111, and therefore the vibration mechanism is greatly simplified.

To explain the swing type sorting device 4 provided in the outer frame 6, 47 is a lower machine frame, and a mounting base 48 is pivotally attached to the upper part of the machine frame 47 by a swing arm 49.50. There is. 51 is a drive shaft, an eccentric cam 52 is attached to the drive shaft 51, and a rod 53 of the eccentric cam 52 is attached to the swing arm 4.
It is pivoted near the upper end of 9.

At this time, as shown in FIG. 12, the angle θ between the swinging arm 49 and the rod 53 is smaller than a right angle. Therefore, when the eccentric cam 52 rotates, the mount 48 becomes a quick return. The ratio is 1:1. A range of 0.01 to 1.2 is preferable.

The lower end of the swinging arm 50 is pivoted to a vertically moving shaft 54 . Both ends of the vertical movement shaft 54 are fitted into vertical guide grooves 55 attached to the machine frame 47 so as to be vertically movable. A rotary shaft 56 is provided above and parallel to the vertically moving shaft 54 and is freely rotatable. Opposite screws 57.58 are carved on the left and right sides of the rotation shaft 56 from the center, and pieces 59.60 are screwed into the opposite screws 57.58, respectively.
Bosses 61 and 62 are attached to the outer periphery of the vertical movement shaft 54 at a position outside of 0, and a rod 63 is pivotally attached between the top 59 and the boss 61. A rod 64 is pivotally attached to.

65 is a handle for manually rotating the rotating shaft 56;
Further, 66 is a forward/reverse motor, 67 is a sprocket attached to the rotating shaft, 68 is a tin rocket attached to the rotating shaft 56, and 69 is a chino, which automatically rotates the rotating shaft 56 by a sensor installed on the sorting plate. Sometimes it is rotated.

Therefore, when the rotating shaft 56 is rotated, the rod 63.6
4 gradually changes from the tilted state to the upright state. Therefore, the vertical movement shaft 54 is moved downward, and the mounting base 4 is moved through the swinging arm 50 attached to the vertical movement shaft 54 in FIG.
Only the right end of 8 is moved down, and the opposite is exactly the opposite.
The right end of the mounting base 48 moves upward.

Regarding the sorting plate 70 attached to the upper part of the mounting base 48, as shown in FIG. 14, a large number of protrusions are formed on the plate surface. The sorting plate 70 is a square in the shape of an overhead eyelid, and is provided with a left-sided protrusion 72 that is inclined toward one side 71 on approximately the front four-fifths of the entire body, and a left-sided protrusion 72 that is inclined toward one side 71 on approximately the rear one-fifth of the entire body. A right inclined protrusion 74 is formed which is inclined in the direction.

The rear side of the − side 71 is closed by a rising wall 75 . Reference numeral 76 is a brown rice outlet, and the opening degree is adjusted by an adjustment plate 78 that moves back and forth by loosening a manual screw 77. 41! n will be done.

The front side of the other side 73 is closed by a rising wall 79, and a paddy outlet 80 is opened at the rear side of the other side 73. The paddy outlet 80 has a screw 81
The degree of opening is adjusted by loosening the adjustment plate 82, which moves back and forth. 83 is a brown rice outflow gutter, and 84 is an unhulled rice outflow gutter. The sorting plate 70 has an embodiment in which the front plate 85 and the rear plate 86 are formed separately, and an embodiment in which they are not formed separately.The left inclined protrusion 72 and the right inclined protrusion 74 are formed on a single stainless steel plate. It may be formed in the same direction.

The 13th Ui4 shows a state in which a left inclined protrusion 72 and a right inclined protrusion 74 are simultaneously formed on one sorting plate 70 by press working.

In actual use, brown rice is much more common than unhulled rice, so the front plate 85 on which the left inclined protrusion 72 is formed is replaced with the right inclined protrusion 7.
The area is much larger than that of the rear plate 86 formed with 4.

As shown in FIG. 4, the sorting plates 70 are provided in multiple stages. Therefore, on the top of the sorting plate 70 there is a distribution device 87 that reaches each stage.
is provided.

One end 88 of the distribution device 87 is slightly higher than the other end 89. The width of one end 88 is formed to be approximately the same as the width of the wind selection section 3. The distribution device 87 has the same width from beginning to end from one end 88 to the other end 89, and a weir 90 is provided in the middle.The other end 89 is provided with partition plates 91 equal in number to the number of sorting plates 70 to prevent the flow. An outlet 92 is formed.

Thus, the upper part of the receiving gutter 116 is opened at the lower part of the passage 114, and the lower end opening of the receiving gutter 116 is opened at the upper surface of the hopper 115 that reaches the upper two to three stages of sorting plates 70. Therefore, when switching the switching valve 113 to the position shown by the temporary line,
The grains flow from the passage l14 to the hopper 115 via the receiving gutter 116, and are supplied only to the two to three stages of sorting plates 70 above the hopper 115.

Reference numeral 93 denotes an inlet for finished rice formed at the lower end of the take-out elevator 5; 94 denotes a discharge gutter formed at the upper end of the take-out elevator 5; a return gutter 96 and a take-out gutter 97 are formed via a switching valve 95; be done. 98 is a storage tank, 99 is its drop port, 10.
0 is a guide pipe, 101 is an on-off valve, 102 is a control valve, and 103 is a control screw.

The lower end 104 of the guide pipe lOO is open above the socket 105 that reaches the top of the sorting plate 7°. However, when the lower end 104 of the guide pipe lOO is opened above the receiving trough l16 reaching the upper two to three stages of the sorting plate 70, it is returned to the upper two to three stages.

106 is a return port formed at the bottom of the elevator l, 107 is a discharge gutter leading to the supply tank 8, lo8 is a staked hopper, 10
9 is an immature grain extraction port, ll.

is an adjustment plate.

Next, we will discuss the effect.

Set the switching valve 113 to the position indicated by the solid line in FIG.
ot is completely closed, the switching valve 95 is in the position indicated by the solid line, and the control valve 10 is in the closed state. When paddy rice a is put into the loading hopper 108 formed at the bottom of the elevator L, the elevator L is raised. Then, it flows into the supply tank 8 from the discharge gutter 107. Therefore, when the control valve lO attached to the connecting tube 9 at the lower end of the supply tank 8 is opened manually or automatically, the unhulled rice a is fed out little by little by the rotation of the feeding roll 14 and collides with the inclined plate 15. The rice is fed to the middle of rubber rolls 16, 17 along the inclination of the grain, is hulled between the rubber rolls 16, 17, and is discharged to the discharge side 18.

This hulled material collides with the diffuser 19, jumps over the front rising edge 26 on the front side of the diffuser 19, hits the reflector plate 27, is reflected by the reflector plate 27, and flows to the inclined guide plate 28, 29. It passes between the inclined guide plates 28 and 29 and falls into the wind selection chamber 33.

At this time, the radius 20 of the hulling section 2 is formed only by the width of the rubber roll 16.17, and is small, but when the grains are reflected on the reflection plate 27, they move in the axial direction of the rubber roll 16.17. It is diffused and flows into the diffusion chambers in the diffusion tubes 24 and 25 formed on the left and right sides of the hulling section 2, and is evenly spread over the width 21 of the wind selection section 3, and then the slope guide of the wind selection section 3 Board 28.29
supplied to The inclined guide plates 28 and 29 are both installed at a gentle slope, and the grains supplied thereto do not flow down under their own weight, but the inclined guide plates 28 and 29 are installed at a gentle slope.
An eccentric cam 43 is attached to the shaft 31, and the other end of a connecting rod 44 whose one end is fixed to the eccentric cam 43 is fixed to the side wall of the wind selection section 111 of the wind selection section 3. Also, in the embodiment of FIG. 5B, wind selection (f l l
Since the outer ring 112 of the eccentric cam 43 is directly fixed to the outer ring 112 of the eccentric cam 43, when the shaft 31 rotates at high speed, the wind selection part 11 of the wind selection part 3 has a width of about 1 to 3 mm through the eccentric cam 43 and the connecting rod 44. The inclined guide plate 28.2 vibrates violently in the direction of the arrow.
Even if the slope 9 is gentle, the rice grains are smoothly diffused in the width direction and uniformly flowed into the winnowing chamber 33. Since the wind sucked from the suction port 32 is blown into the wind selection chamber 33 by the cross-flow windmill 30, the light rice husks C are blown up into the suction path 34, sucked by the blower 35, and discharged.

The mixed rice of unhulled rice a and brown rice that has fallen through the wind selection chamber 33 is stored in the hopper 36, but at this time, immature grains are sorted and taken out from the takeout port 109.

When the storage amount in the hopper 36 reaches a certain level, the arm 39 moves downward against the elasticity of the spring 40, and the on-off valve 38 opens around the shaft 37, distributing grains uniformly across the entire width. let it fall. The fallen mixed rice is supplied to a distribution device 87.

Since the distribution device 87 is violently vibrated in the front-rear direction via the rod 53 due to the rotation of the eccentric cam 52 of the drive shaft 51, the vibration is diffused to the full extent in the width direction of the distribution device 87.
When these flow from one end 88 toward the other end 89,
It jumps over the weir 90 and spreads evenly, and is partitioned by a partition plate 91 provided at the other end 89 to form each outlet 9.
2 and is supplied to each sorting plate 70.

When the drive shaft 51 of the sorting plate 70 rotates, the eccentric cam 52 rotates, and the mounting base 48 is reciprocated in the horizontal direction as shown by the arrow in FIG. 12 via the rod 53 attached to the eccentric cam 52. A swinging arm 49 supporting the mounting base 48
Since the angle θ formed by the rod 53 is smaller than a right angle, when the sorting plate 70 moves forward in a quick return, it moves at a slow speed, but when it moves backward, it moves quickly. Therefore, as the sorting plate 70 moves back and forth, the mixed rice of unhulled rice a and brown rice slough supplied to the sorting plate 70 from the outlet 92 is separated as shown in FIG. 15, and the separated brown rice slough is removed. Brown rice flows into the brown rice outflow gutter 83 from Roaro, flows into the inflow port 93 from the brown rice outflow gutter 83, and ascends the take-out elevator 5. Then, when the cutting valve 95 is switched to the temporary line position, it can be taken out from the takeout gutter 97.

On the other hand, the separated unhulled rice a is guided by the right inclined protrusion 74 and flows out from the unhulled rice outlet 80 into the unhulled rice outflow gutter 84, flows from the unhulled rice outflow gutter 84 into the return port 106 of the elevator l, and is combined with the supplied unhulled rice a. join together.

As the work nears completion, the amount of mixed rice stored in the hopper 36 decreases and cannot be fed to the multi-stage sorting plate 70. The liquid is switched to the position shown in FIG. 1, and is supplied from the passage 114 through the receiving gutter 116 and the hopper 115 to only the upper two to three stages of sorting plates 70 for sorting.

(If the amount supplied to each stage is not appropriate and the separating action of the sorting plate 70 is no longer effective, both the unhulled rice a and brown rice will flow out from the unhulled rice outlet 80 to the unhulled rice outflow gutter 84, so the switching valve 9
5 to the position indicated by the solid line in FIG. 1O, the water can be stored in the storage tank 98 via the return gutter 96. By forming the guide pipe 100 like a temporary wire, the stored mixed rice is transferred to the lower end 104 of the guide pipe lOO.
It is then supplied onto the receiving gutter 116 that reaches the upper two to three stages of the sorting plate 70 and is returned to the upper two or three stages. ) The present invention provides a wind-selecting section for wind-selecting the grains grown in the hulling section at the lower part or side of the hulling section, and a wind-selecting section located near the wind-selecting section. A multi-stage sorting section for separating and sorting mixed rice is provided, and the supply section of the multi-stage sorting section includes a distributing device that evenly supplies the mixed rice to each stage of sorting plates, and a distributing device that supplies the mixed rice evenly to each stage of sorting plates, and A flow path is formed to supply mixed rice only to the top two or three plates instead of just one plate, so that when the amount of mixed rice is low, it is sorted only by the top two or three sorting plates. The hulling device and the sorting plate have a horizontally swinging structure, and have a brown rice outlet on one side of the left and right sides with respect to the swinging direction, a paddy rice outlet on the other side, and a middle rice outlet. (a) Since the middle rice is not returned to the elevator and circulated, there will be no oversupply, and therefore the adjustment tank suspended by a spring is Since it is not necessary, the structure is simple and the height is low.

Not only the top one of the opening 0 sorting plates 70 but the top two to
A flow path is formed to supply the mixed rice to three plates, and when the amount of mixed rice becomes low, it is sorted by the two to three sorting plates at the top, so the multi-stage sorting of the oscillating sorting device is possible. The surface area of the board can be reduced.
