Description

[Detailed description of the invention] The present invention relates to a rice hulling device.

The present invention is a hulling device for removing rice hulls in a relatively large amount, and in particular, the structure of the hulling section has been specially devised.

In the present invention, when the hulled material that has been hulled in a narrow hulling chamber is sent to the wind selection chamber to remove the rice husks, the hulled material is uniformly spread across the width of the wind selection chamber. By supplying it to the wind selection room, we hope to improve the wind selection effect and also reduce the height of the hulling device. It is designed so that other effects can be expected.

Since the present invention has devised the structure of each other related structure, the overall structure will be explained as follows.

Moreover, Ei L≠4, in the present invention, when the discharge 1 of the rubber roll of the hulling section that houses a pair of rubber rolls collides with the hulled material that has been washed up on the rubber rolls and spreads in the axial direction of the grain rolls. At the same time, a diffusion chamber was formed on both sides of the part in the axial direction, so that the particles were diffused in the diffusion chamber and fell into the wind-selecting chamber to be wind-selected. The hulling device and the pair of rubber rolls are arranged diagonally above and below so that the hulling material obliquely collides with the diffuser; form,
a hulling device in which the hulling material is spread in the axial direction of the rubber roll by jumping over the front rising edge, and
A pair of rubber rolls are arranged diagonally above and below so that the hulled material is discharged obliquely from the rear side to the front side, and the released hulled material is placed in the diffusion chamber formed on the discharge side of the rubber rolls. The gist of the invention is a configuration of a hulling device equipped with a reflecting plate that reflects light.

In explaining the overall structure of the present invention, the structure of the conventional one will be explained as follows.

FIG. 1 is a diagram of a known example, where A is a supply hopper into which unhulled rice a is input, B is a hulling section provided at the lower part of the supply cup A, and inside the hulling section B there is a pair of Rubber rolls C and C are attached to the shaft. A wind sorting section is provided at the bottom of the hulling section B, where the lightweight rice husks C are wind sorted, and the hulled brown rice and the remaining unhulled rice A are mixed and guided to the side. Then, it flows into the lower part of the elevator E on the side. A tank F, commonly called a control tank, is attached to the upper end of the elevator E. The adjustment tank F is suspended by a spring and moves up and down depending on the storage amount. By this vertical movement, the /<lub at the outlet of the supply hopper A is opened and closed in conjunction with each other via a wire or the like. From the adjustment tank F, the rice is transferred 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 b is sent to the elevator as finished rice.
It is extracted by

The deficiencies of the prior art are as follows: (a) Since the supply hopper A is located high, it is difficult to supply the unhulled rice a.

Since there is an adjustment tank F suspended by a spring, the structure is complicated.

C. Thrower H for returning paddy and rice is required.

Second, the entire structure becomes larger.

That is the point.

FIG. 2 is an overall schematic diagram of the newly developed invention, in which 1 is an elevator for feeding unhulled rice a, 2 is a hulling section, and 3 is a winnowing section. The rice hulling section 2 and the wind sorting section 3 are provided above the swing type sorting device 4. 5 is an elevator for taking out brown rice, which does not have the tank F suspended by the spring shown in FIG. 1 and the thrower H for return.

Referring to FIGS. 3 and subsequent figures, reference numeral 6 denotes an outer frame of the swing-type sorting device 4, and the swing-type sorting device 4 is provided inside the outer frame 6. The outer frame 7 of the wind selection section 3 is placed on the upper part of the outer frame 6. As shown in FIG. 4, the outer frame 6 and the outer frame 7 have approximately the same size, are square frames, and are entirely assembled from angle steel. 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.

A manual control valve lO is installed in the connection tube 9 at the bottom of the supply tank 8.

The bottom end of the swings. 14 is a feed roll.

The feed roll 14 is rotated by a motor and feeds out the unhulled rice a so as to collide with the inclined plate 15 at the bottom thereof. The tip of the inclined plate 15 faces the middle of the rubber rolls 16 and 17.

The com roll 16 is in the diagonally upper position, and the rubber roll 17
is the diagonally downward position. A diffuser 19 having a U-shaped cross section as shown in FIGS. 8 and 9 is provided on the discharge side 18 of the rubber rolls 16, 17. The diffuser 19 is like a gutter, and is formed so that when the hulled rice is violently hit by the rubber rolls 16 and 17, it spreads evenly in the axial direction of the rubber rolls. The hulling section 2 is formed to have a width 20 in which the rubber rolls 16 and 17 are accommodated, and the width 20 is small as is known, and is much smaller than the width 21 of the wind selection section 3, which will be described later. A diffuser 19 is provided to evenly spread the hulled rice in the hulling section 2 to the width 21 of the outer frame 7, and walls 22.2 on the left and right sides of the hulling section 2 are provided.
3 are respectively cut out and the diffusion tubes 24 and 25 are connected to each other. Since the object colliding with the diffuser 19 jumps forward over the front rising edge 26, a reflecting plate 27 is provided on the front side of the diffuser 19 to reflect it back again. The reflector 27 is provided through the diffuser tube 24.25 and is connected to the diffuser 19.
The object that collided with the front edge 26 flew over the reflecting plate 2.
7 and is reflected to the rear side, the diffuser tube 24.
It is fully diffused within 25 days.

The wind selection section 3 provided within the outer frame 7 has a structure that vibrates slightly. The wind sorting section 5 has inclined guide plates 28 and 29 that receive grains that are reflected and fall from the reflecting plate 27, and the inclined guide plates 2
8. A cross-flow wind turbine 30 is mounted below the shaft 31 with a shaft 31. 32 is an inlet of the cross-flow windmill 30.

A wind selection chamber 33 is formed in the wind selection section 3 in which the grains falling from the inclined guide plates 28, 29 are subjected to air selection. A suction path 34 for rice husk C is formed in the upper part of the wind selection chamber 33, and the suction path 3
4 to the blower 35. Therefore, the rice husk C is discharged outside the machine through the suction path 34 and the blower 35.

The lower part of the wind selection chamber 33 forms a hopper 36 which is open in the direction of the width 21, and one side of the hopper 36 is an on-off valve 38 whose upper end is pivoted with a shaft 37. The on-off valve 38 opens and closes around the shaft 37 to allow the grains to fall uniformly in the width direction. Axis 3

An eccentric cam 43 is attached to the shaft 31, and the other end of a leaf spring 44 whose one end is fixed to the eccentric cam 43 is fixed to the side wall of the wind selection section 3. The wind selection section 3 is a container that vibrates slightly, and the diagonal rod 45
．． It is suspended from the outer frame 7 by 46. Therefore, when the shaft 31 rotates at high speed, the eccentric cam 43 and the leaf spring 4
4, the wind selection section 3 violently vibrates in the direction of the arrow.

The opening/closing valve 38 opens against the elasticity of the spring 40 when a certain amount of grain is poured into the hopper 36.

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 swing arms 49, 50-. ing. Reference numeral 51 denotes a drive shaft. An eccentric cam 52 is attached to the drive shaft 51, and a rod 53 of the eccentric cam 52 is pivotally attached near the upper end of the swing arm 49.

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 OI to 1.2 is preferable.

The swinging arm 50 has a lower end pivotally attached 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, and are vertically movable. A rotation shaft 56 is provided above the vertical movement shaft 54. Rotating shaft 5
Opposite screws 57 and 58 are formed on the left and right sides of the center of 6, and pieces 59 and 60 are screwed into the opposite screws 57 and 58, respectively.

A rod 63 is pivoted between the pieces 60 and 62, and a rod 64 is pivoted between the piece 60 and the post 62. 65 is a handle for manually rotating the rotating shaft 56, 66 is a forward/reverse motor, 67 is the rotating shaft, 68 is a sprocket attached to the rotating shaft 56, and 69 is a chino, which rotates the rotating shaft 56 by a sensor to be described later. to rotate automatically.

Therefore, when the rotating shaft 56 is rotated, the rod 63.6
4 gradually changes from the tilted state to the upright state, so that the vertically moving shaft 54 is moved downward, and the mount 48 is moved downwardly via the swinging arm 50 attached to the vertically moving shaft 54.

To explain the sorting plate attached to the mounting base 48, as shown in FIG. 14, a large number of protrusions are formed on the plate surface. The sorting plate 7o has a rectangular ridge shape, and is provided with a left inclined protrusion 72 that is inclined toward one side 71 on the front two-thirds of the plate, and is inclined toward the other side 73 on the rear one-third of the plate. A right-slanted protrusion 74 is formed. The rear side of the − side 71 is a rising wall 75
occlusion. Reference numeral 76 denotes a brown rice outlet, and the degree of opening is adjusted by an adjustment plate 78 that moves back and forth by loosening a manual screw 77. 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 opening degree of the paddy outlet 80 is adjusted by an adjustment plate 82 that is moved back and forth by a screw 81. 83 is a brown rice outflow gutter, and 84 is an unhulled rice outflow gutter. When the sorting plate 70 is formed separately on the front plate 85 and the rear plate 86, the left inclined protrusion 72 and the right inclined protrusion 74 may be attached to a single stainless steel plate in opposite directions. .

FIG. 13 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.

The sorting plates 70 are provided in several stages as shown in FIG. Sorting board 7
0 is provided with a distribution device 87 extending to each stage. The hopper 36 opens in the middle between the front and rear sides of the sorting plate 70. One end 88 of the distribution device 87 is located at the bottom of the hopper 3°6.
The other end 89 is located in front of the sorting plate 70. One end 88 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 dispensing device 87 has one end 88
The width is the same from beginning to end from the end to the other end 89, and there is a weir 9 in the middle.
0 is set.

At the other end 89, partition plates 91 corresponding to the number of sorting plates 70 are provided to form an outlet 92.

The outlet 92 is connected to the sorting plate 70 of each stage.

93 is an inlet for finished rice formed at the lower end of the take-out elevator 5; 94 is a discharge gutter formed at the bottom of the take-out elevator 5;
By opening the switching valve 95, a return gutter 96 and a take-out gutter 97 are formed. 98 is a storage tank, 99 is its drop port, lOO is a guide pipe, 101 is an on-off valve, 1()2 is a control valve,
103 is an adjustment screw.

The lower end 104 of the guide pipe 100 opens above the socket 105 that reaches the top of the sorting plate 70. 106 is a return port formed at the bottom of the A-disembarker 1, 107 is a discharge gutter that leads to the supply tank 8, and 108 is a It is a stake hopper.

Next, we will discuss the effect.

The tension hole formed at the bottom of the Noboru III machine /%-
When unhulled rice a is put into 108, the elevator 1 is raised and it flows into the supply tank 8 through the discharge gutter 107. Therefore, a control valve lO is attached to the connecting tube 9 at the lower end of the supply tank 8.
When the unhulled rice a is manually opened, 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, and is fed along the slope of the inclined plate 15 to the middle of the rubber rolls 16.17. The paddy is removed between the discharge side 1
It is discharged at 8.

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 width 20 of the hulling part 2 is formed only by the width of the rubber roll 16.17, and is small, but especially when the grains are reflected on the reflection plate 27, they move in the axial direction of the rubber roll 16.17. It diffuses 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 thus the wind selection section 3
After being diffused to a width 21 of , it is supplied to the wind selection 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 mixture of unhulled rice a and brown rice that has fallen through the wind selection chamber 33 is stored in a hopper 36. When the storage amount in the hopper 36 reaches a certain level, the arm 39 moves downward against the elasticity of the spring 40.
Therefore, the on-off valve 38 opens around the shaft 37, allowing the grain to fall uniformly over the entire width direction. The dropped mixed rice is supplied to the distribution device 87 side. 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 distribution device 87 is fully diffused in the width direction. When flowing in the direction of the end 89, it jumps the weir 9o and spreads more evenly, and the partition plate 9 provided at the other end 89
1 , flows into each outlet 92 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, by switching the switching valve 95 to the temporary line position, the product 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.

When the work is completed, the separating action of the sorting plate 70 stops working, and both the unhulled rice a and brown rice flow out from the unhulled outlet 80 to the unhulled rice outflow gutter 84. Therefore, the switching valve 95 is turned to the position indicated by the solid line in Fig. 10. By switching the position, the water can be stored in the storage tank 98 via the return gutter 96. The stored mixed rice flows into the receiving port 105 by opening the on-off valve 101, and is supplied from the receiving port 105 to the uppermost sorting plate 70 to be sorted.

The present invention provides a diffuser on the discharge side of the rubber roll of a hulling section that accommodates a pair of comb rolls, which causes the hulled material that has been hulled by the rubber roll to collide and spread in the axial direction of the rubber roll. A diffusion chamber is formed on both sides of the direction,
Accordingly, the hulling device is configured such that the rice is dispersed in the diffusion chamber and then dropped into the wind-selecting chamber to be wind-selected, and the pair of rubber rolls are arranged diagonally above and below, so that the grains to be hulled are disposed diagonally with respect to the diffuser. A front rising edge rising upward is formed on the front side of the diffuser, and the hulled material is spread in the axial direction of the rubber roll by jumping over the front rising edge. The hulling device and the pair of rubber rolls are arranged diagonally above and below so that the hulled material is discharged diagonally from the rear side to the front side, and is discharged into a diffusion chamber formed on the discharge side of the rubber roll. The gist of the invention is a configuration of a hulling device equipped with a reflecting plate that reflects the hulled material to the front side.
Not only does it allow you to reliably sort the hulled rice, but it also has the feature of being short in height.
