Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a swing-type grain sorting device that mainly separates mixed grains of unhulled rice and brown rice into unhulled rice and brown rice, respectively, in which the inclination angle of the sorting plate is automatically controlled 70. It is.

When the rice is hulled with a hulling device, the unhulled rice that remains unhulled and the combined grains of the hulled brown rice are discharged, so it is necessary to process them into molecules. Various types of separation and sorting apparatuses have already been provided for use in this case, but since the present invention is completely different from conventional ones, it will be explained in detail.

As is well known, the separating and sorting equipment for unhulled rice and brown rice requires only one
There are 11b mesh type mangoku, oscillating type grain sorting device δ, and rotary barrel type gray type.

In either structure, the intermediate rice is taken out, and the intermediate rice is returned to the sorting section by some method and redistributed N1.

That is, the mixed grains supplied to the sorting device are sorted by the sorting device into two types: (1) ... Paddy rice (2) ... Brown rice (3) ... Unseparated paddy rice and unseparated intermediate rice. The unhulled rice in (1) is returned to the hulling device and re-hulled, the brown rice in (2) is taken out as finished rice and is usually polished, and the intermediate rice in (3) is sent to the sorting device. It is returned to the supply section and subjected to the circulatory separation action again.

However, the present invention has been made regarding a sorting device that does not allow the intermediate rice to come out of the plate, and as a result, countless various effects can be expected. .

The following explains why intermediate rice is always produced when conventional sorting equipment separates unhulled rice and brown rice.

Figures 1 to 3 are typical known examples that are most widely used at present. ■ is a sorting plate, and the surface of the sorting plate 1 has two protrusions similar to the number of cicadas, making it rough. It is formed in this way. The sorting plate 1 is moved diagonally back and forth up and down in the direction of the arrow opening, and the grains 3 are moved in the direction of the arrow A by means of two groups of projections.

The sorting plate 1 is placed on the underframe 4.

Reference numeral 5.6 denotes a diagonal rod, the dove end of the diagonal rod 5.6 is pivoted 7.8 on the underframe 4, and a sorting plate 1 is attached to one end of the diagonal rod 5.6.
9.10. 11 is an eccentric wheel, and 12 is a rod.

The sorting plate 1 is square in shape with an upward angle of 11, and is either on the - side or on the supply side 13.
, the other side facing the supply side 13 is a loss side 14 and a supply side 1.
3 is formed higher than the discharge side 4 and is inclined.

In addition, in the lateral direction with respect to the direction connecting the supply side 13 and the discharge side 14, the side that is shifted by l/1 or - is the swinging lower side 15, and the other side is the swinging upper side 16, and the swinging lower side 15 is closer to the swinging upper side 16. It is tilted at a low α angle. When the sorting plate 1 is horizontal,
As shown in FIG. 2, a blank portion A is formed on the swinging side 15. However, if the α angle is tilted Mi as described above, the blank area A will not occur.

A supply funnel 17 supplies the grains 3 from the corners of the supply side 13 and the shaking side 16. The discharge sides 14 are opened across the entire width, and an unhulled rice outlet 1 is provided on the swinging side 15 of the discharge side 14.
8, a brown rice outlet 19 is provided on the swing side 16 of the discharge side 14, and an intermediate bed outlet 20 is provided in the middle thereof.

In this known example, the intermediate bed is supplied onto the sorting plate 1 through a supply funnel 17, and the eccentric wheel 11 is rotated to swing the sorting plate l in the direction of the arrow. The intermediate bed above the sorting plate l is rocked.

Therefore, as a secondary sorting phenomenon, the heavy brown rice sinks to the lower layer, the unhulled rice a floats to the upper layer, and the brown rice in the lower layer is pushed up to the shaking side 16, and as a secondary phenomenon, the brown rice in El in Figure 3 The brown rice is taken out to the unloading port 19 along the trajectory. The unhulled rice a, which has a light specific gravity, slides on the brown rice and drifts to the rocking side 15 like E2, and is taken out at the unhulled rice take-out 1'' 18, and in the middle,
The unseparated intermediate bed like E3 is distributed and taken out to the intermediate bed outlet 20.

As mentioned above, the known examples are Min+? ! The intermediate floor that is not
The wood is distributed as shown in Fig. 3 and taken out to the intermediate bed outlet 20, and therefore an intermediate wood ashing device is always required.

However, in the present invention, the above-mentioned intermediate bed is not discharged, and therefore, the return mechanism is not required. A raised front earthen wall and a rear standing upper wall are formed on each side, and a raised left upper wall is formed on the rear part of the left edge of the sorting plate, and no raised wall is provided on the front part. A single brown rice outlet is formed, and an upright right upper wall is formed in the part other than the rear part of the right edge of the sorting plate, and a paddy rice outlet is formed in the rear part without the raised wall. The front 2/3 of the plate surface of the sorting plate is provided with a brown rice inclined protrusion that is inclined in the direction of the brown rice outlet, and the rear 1/3 of the plate surface of the sorter plate is provided with a brown rice inclined protrusion that is inclined in the direction of the unhulled rice outlet. A sloping protrusion for rice and paddy is provided, and a supply port is formed on the right side of the front edge, and a device for adjusting the inclination angle in the front and back direction is attached to the sorting plate, and a supply port is provided near the rear edge of the plate surface of the sorting plate. A brown rice blank sensor is installed on the left side, an unhulled rice detection sensor is installed near the unhulled rice outlet, and the sensor, etc. is connected to an inclination angle adjustment device. An unhulled rice blank detection sensor is installed near the inner side of the right standing wall in front of the exit, and a brown rice detection sensor is installed at the innermost front of the brown rice outlet, and the sensor is connected to a tilt angle adjustment device. This is a configuration of an automatic control device in a grain sorting device.

The oscillating grain sorting device of the present invention will be explained with the help of a diagram.
In FIG. 4 and subsequent figures, reference numeral 21 denotes a sorting plate of the present invention, which is usually formed in a multi-stage state. 23
is longer, and the shape of the enemy is a rectangular shape with long sides on the left and right sides. At the front edge of the sorting plate 21, front upstanding upper walls 24 are formed across the entire width, and similarly, at the rear edge of the sorting plate 21, a rear upstanding upper wall 25 is formed over the entire width. However, the sorting plate 21
On the plate surface of 273, a group of 26 brown rice inclined protrusions whose tips are directed toward the left if it is on the left side of the left side is formed on the entire plate surface. In this case, a group of 27 inclined protrusions of unhulled rice facing rightward on the right side of the left and right sides are formed on the entire board surface. As is clear from the cross-sectional view of FIG. 9, the brown rice inclined protrusion 26 and the unhulled rice inclined protrusion 27 are both formed in a direction to draw the grain toward the front upper wall 24 of the leading edge.

A brown rice outlet 28 is formed in the left front part of the sorting plate 21, and the rest is closed by a left standing upper wall 29. A paddy/rice removal IJ 30 is formed at the right rear portion of the sorting plate 21, and the rest is closed off by a right upright wall 31.

32 is a supply hopper, which is provided on the front side of the side where the unhulled rice outlet 30 is provided. The lower end of the front support rod 34a is pivoted 47 to the front side of the support 33. An adjustment rotating shaft 37 is attached to the rear side of the support base 33 so that it can only rotate freely. Adjustment rotation shaft 37
Opposite screw grooves 42a and 42b are formed on both left and right sides from the center, respectively, and pieces 38a and 38b are screwed into the screw grooves 42a and 42b, respectively. A vertically movable rod 42 is provided at the do side position of the adjustment rotation shaft 37 so as to be freely movable two times downward, and the bosses 41a and 41b are freely fitted to the vertically movable rod 42 only by rotation 'I'/i. and the boss 41a, the arm 3
9a piece 38b and boss 4. arm 39 between l b
Attach each b. Further, the lower end of the rear support rod 34b is pivotally attached to the vertically movable rod 40, and the front support rod 34a and the rear support rod 3
A mounting base 45 is pivotally attached to the upper end of 4b.

Therefore, the sorting plate 21 is pivoted to the upper surface of the left side of the picking stand 45 via the pivot attachment part 43, and the top 4 is attached to the right end of the mounting stand 45.
A vertical adjustment shaft 46 is screwed onto the top 44, and one end of the adjustment shaft 46 is engaged with the lower end of the sorting plate 21.

35 is an eccentric wheel, and 36 is a rod, and the angle between the rod 36 and the support rod 34 is smaller than a right angle. FIG. 5 is a perspective view of the rod 36, which shows that the rod 36 is wider toward the top.

A forward/reverse motor 48 is attached to the rear end of the adjustment rotation shaft 37, and a brown rice blank sensor 49 is installed near the inner side of the rear upper wall 25 of the sorting plate 21 and near the left upper wall 29. A paddy rice detection sensor 5 is located near the paddy rice take-out 130.
0, a paddy rice blank sensor 51 is provided in front of the unhulled rice outlet 30 and inside the right standing upper wall 31, and a brown rice detection sensor 50 is provided at a position near the brown rice outlet 28 inside the front upright upper wall 24.
These are connected to a forward/reverse motor 48.

Next, we will discuss the effect.

In the present invention, due to the following configuration, when the eccentric wheel 35 is rotated, the angle between the rod 36 and the support rod 34 is smaller than a right angle, so the sorting plate 21 is moved toward the front side at a ratio of 1:1.01 to 1.2. When moving further to the rear, it moves faster; when moving farther to the front, it moves slower.

Therefore, the intermediate rice between unhulled rice a and brown rice
When fed to the sorting plate 21, the unhulled rice a and brown rice are initially in a completely intermediate state as shown in FIG. As a result, brown rice with a heavy specific gravity sinks to the lower layer, and unhulled rice a with a lighter specific gravity floats to the upper layer of the brown rice group. It comes into contact with the sloping protrusion 27 of unhulled rice.

In this way, the brown rice inclined protrusion 26 and the unhulled rice inclined protrusion 27
Under the influence of the slowly moving inclined protrusions 26 and 27, the bottom layer of brown rice that has come into contact with It is deposited relatively thickly at 273. Contrary to this, the rear half of the 1/3 of the sorting plate 21 becomes relatively thin. In this way, brown rice scum accumulates relatively thickly on 2/3 of the sorting plate 21, and becomes relatively thin on 1/3 of the sorting plate 21.
When 1 returns, it returns relatively quickly and the inclined protrusion 26
．． Since the plate 27 is lower in the direction of movement, it acts to place the grain as it is, so that 2/3 of the sorting plate 21
The unhulled rice a floating on the surface of the brown rice rack slides on the inclined surface of the brown rice rack and moves toward 1/3 of the sorting plate 21.

As a tertiary phenomenon, when the above operation is repeated, the brown rice that has accumulated thickly on the front half of the sorting plate 21 is removed by the action of the tip of the brown rice inclined protrusion 26, and the brown rice is removed from the front soil wall 2 on the front side.
Start moving to the left along 4. At this time as well, sorting plate 2
The brown rice that is in contact with the inclined protrusions 26 and 27 on the plate surface of No. 1 continues to be subjected to the sorting action described above while moving to the left, so that as it moves along the front upper wall 24, the layer of brown rice gradually becomes As the thickness increases, a portion of the first layer of brown rice grains will flow to the rear half of the sorting plate 21, and when the brown rice grains reach the left end of the sorting plate 21, the purity will increase. The brown rice improves and becomes complete brown rice, which is taken out to the brown rice outlet 28. In this case, brown rice outlet 2 of the brown rice bowl
The movement in the eight directions is mostly carried out by the tip of the brown rice inclined protrusion 26, but since the brown rice inclined protrusion 26 has a much larger area than the unhulled rice inclined protrusion 27, it is possible to ensure the transfer of the brown rice. go to

On the other hand, unhulled rice (a) is deposited on the rear half of the sorting plate 21 by tearing a layer of brown rice grain on the inclined surface, but in the rear half of the sorting plate 21, the unhulled rice sloping protrusion 27 is deposited as a quaternary phenomenon. As a result of this action, it is transferred to the right side of the sorting plate 21. However, due to the action of the unhulled rice sloping protrusion 27, the unhulled rice a is advanced to the right side of the sorting plate 21, and the secondary phenomenon is still being sorted, so the unhulled rice a gradually becomes less pure as it advances toward the unhulled rice outlet 30. The rice increases and finally becomes complete unhulled rice and is taken out from the unhulled rice outlet 30.

The above-mentioned tertiary phenomenon, that is, the movement of the brown rice tray toward the brown rice outlet 28, and fourth phenomenon, that is, the movement of the unhulled rice toward the unhulled rice outlet 30, is performed by adjusting the left and right inclinations of the sorting plate 21.

That is, by rotating the adjustment shaft 46, the horizontal inclination of the sorting plate 21 is adjusted, and depending on the degree of inclination, the tertiary phenomenon and the quaternary phenomenon can be finely adjusted.

During this time, the intermediate rice is accumulated in the center of the sorting plate 21 and rotates around, and the newly supplied brown rice and unhulled rice a are only metabolized and never leave the sorting plate 21.

The above-mentioned sorting state is automatically adjusted by the forward/reverse motor 48 and each sensor from the brown rice blank sensor 49 to the brown rice detection sensor 50. That is, in the case of the present invention, the grain distribution on the sorting plate 21 has one tendency: (a) The brown rice blank sensor 49 part is a blank opening, and the part of the unhulled rice sensor 50 has unhulled rice (c), unhulled rice blank. The best performance is achieved only when the sensor 51 part is blank and the brown rice detection sensor 50 part is brown rice. Therefore, brown rice blank sensor 49, unhulled rice detection sensor 5
0, a paddy rice blank sensor 51 and a brown rice detection sensor 52 are provided in each part, which rotates the forward/reverse motor 48,
When the arms 39a and 39b are adjusted from an inclined state to an upright position, the vertically movable rod 4o moves up and down, the mounting base 45 is adjusted back and forth, and the sorting plate 2 attached to the mounting base 45 is adjusted.
1 has its front and rear inclination angles adjusted. Therefore, when the brown rice blank sensor 49 detects that there is grain, since the rear side is low, the forward/reverse motor 48 rotates it slightly in the forward direction, and when the unhulled rice sensor 50 no longer detects that there is unhulled rice, the rear side is low. Since it is high, the adjustment rotating shaft 37 is reversed by the forward/reverse motor 48 to lower the rear side.

In other words, A. When there is grain in the brown rice blank sensor 49 area,
Lower the rear.

When there is no unhulled rice a at the mouth or at the unhulled rice detection sensor 50, lower the rear part.

C. When there is grain in the paddy/rice blank sensor 51,
Raise the rear.

2. If there is no brown rice in the brown rice detection sensor 52 area, raise the rear part.

In the above embodiment, four sensors are provided on the sorting plate 21, from the brown rice blank sensor 49 to the brown rice detection sensor 52, but the present invention can be carried out with only the brown rice blank sensor 49 and the unhulled rice detection sensor 50. The front and rear edges of the sorting plate, which is rectangular in shape, form an upstanding front upper wall and rear (l upper wall), respectively, and the rear part of the left edge of the sorting plate has an upright left upright wall. The upper wall is formed, and the front part is not provided with a rising wall to form a brown rice outlet, and the part excluding the rear part of the right edge of the sorting plate has a raised shape (right)'f, -1:, A wall is formed, and the rear part is not provided with a rising wall to form a paddy rice outlet, and the front two-thirds of the plate surface of the sorting plate is provided with a brown rice inclined protrusion that is inclined in the direction of the brown rice outlet. A sloping protrusion is provided on the rear 1/3 of the plate surface of the sorting plate, which is inclined in the direction of the unhulled rice outlet, and a supply port is formed on the right side of the front edge. A tilt angle adjustment device is installed, a brown rice blank sensor is installed on the left side near the rear edge of the plate surface of the sorting board, a paddy rice detection sensor is installed near the unhulled rice outlet, and the sensor and the tilt angle adjustment device are installed. an automatic control device in the oscillating grain sorting device δ, which is connected to a brown rice blank sensor at a position on the left near the rear edge of the plate surface of the sorting plate, and an unhulled rice detection sensor at a position near the unhulled rice outlet. A paddy rice blank detection sensor was installed near the inner side of the right standing wall in front of the unhulled rice outlet, and a brown rice sensor was installed at the innermost front part of the brown rice outlet, and the sensor, etc. was connected to the inclination angle adjustment device. Since it is an automatic control device in a swing type grain sorting device, A. It can be sorted without removing intermediate rice, which simplifies the structure.

B. Sorting can be done automatically in the best condition.
