This is a configuration for turning on and off.

Reference numeral 56 denotes an adjustment lever movably provided in an operation groove 57 of the operation panel. In this embodiment, the adjustment lever is provided on an operation panel disposed near the paddy hopper 6.

And a brown rice switching groove 57b for switching the grains selected by the lower swinging sorting device 3 between the in-machine circulation state and the out-machine removal state.

When the adjustment lever 56 is at the position (A), the rice supply control valve of the rice hulling unit 1 is in a fully closed state. In the position (B), it is in the fully open state. Next, at the position (B), the adjustment lever 56 is moved slightly to the left, and the brown rice switching groove 57b is moved from the position (B) to the position (C). Then, in the position (B) of the brown rice switching groove 57b, the adjustment lever 56 is sorted by the swing sorting device 3, and the brown rice taken out from the uppermost rocking position is switched to the in-machine circulation side by the brown rice switching valve (not shown).

As described above, while holding the adjustment lever 56, the opening and closing operation of the paddy supply control valve, the switching operation of the brown rice switching valve (not shown), the adjustment of the lateral inclination angle of the swing selection plate 15, and the on / off of the swing clutch are performed. It is easy and easy to operate. Next, with reference to FIG. 8, another embodiment of the concavo-convex shape for selection formed on the swing selection plate 15 will be described.

The configuration of the unevenness of the swing sorting plate 15 in the above embodiment is constituted by a convex sorter or a concave sorter having the same shape, whereas in this embodiment, FIG.
It is configured as follows. Convex sorter 6
.. Are formed on the swing sorting plate 15 in a large number on the supply side 15a, and sequentially or gradually in a small size on the discharge side 15b. Then, the upright height of the pushing surface 62a of the discharge side 15b is set to the height of a specific grain having a large specific gravity and a small grain such as brown rice for sorting mixed rice. a (usually 2
Millimeter level) ~ Half height of a, supply side 1
In 5a, for example, the height is gradually reduced from the height 2 × a toward the discharge side.

The convex sorter 62 is configured as follows, as shown in a perspective view in FIG. Pushing surface 62 standing at an angle of about right angle to about 70 degrees from the plate surface
a, an upper flat surface 62b connected to the lower side from the upper end edge of the pushing surface 62a, an ascending guide surface 62c connected downwardly to an end edge of the upper flat surface 62b on the lower side 15d, and an upper flat surface 62b
And a discharge side guide surface 62d connected downwardly to an end edge of the upper flat surface 62b on the discharge side 15b.

When the convex sorter 62 is formed on the plate surface, as shown in FIG. 8A, the pushing surface 62a is moved in the vertical direction of the swing sorter plate 15 in the flow direction of the grain. Are arranged in rows at predetermined intervals along a straight line along
.. Are arranged in a zigzag manner. Note that the convex sorter 62 may be configured as shown in FIG. 8 (3). That is, the upper flat surface 62b of the embodiment shown in FIG. 8A is omitted, and the pushing surface 62b is provided on the swinging upper edge of the rising guide surface 62c.
a, the supply-side guide surface 62d is connected to the supply-side edge of the ascending guide surface 62c, and the discharge-side guide surface 62e is connected to the discharge-side edge of the ascending guide surface 62c.
Then, the area of the convex sorters 62 can be made small, and a large number of convex sorters 62 can be arranged and formed on the plate surface, so that the sorting efficiency can be improved.

Further, instead of the convex convex sorter 62, a concave with a pushing surface is formed by a concave bottom, and the depth of the bottom concave is made deep on the supply side 15a and shallow on the discharge side 15b. It is good also as a structure which performs. When the convex sorters 62 are arranged in a row, the convex sorters 62 may be arranged in a row at a predetermined angle with respect to the vertical direction. In addition, swing sorting plate 1
Only in the supply side 15a portion where the mixed rice is supplied in 5, the rising height of the pushing surface 62a may be increased, and the other portions may be configured to have the same height and lower.

In the conventional swinging and separating plate of the swinging and separating plate, the supply side 15a and the discharge side 15b are formed of the same height of the separation projection (or the same depth of the separation recess).
For this reason, in the thick grain layer portion on the supply side 15a, the floating of the paddy from the brown rice layer is delayed, and the length of the swing sorting plate in the flowing direction becomes long, and there is a problem that the plate surface cannot be downsized. .

When observing the movement of the grains at the time of sorting on the swinging sorting plate 15, when the grains are sorted by reciprocating swinging from the swinging side 15c to the swinging side 15d, they are projected by the forward movement to the swinging side 15c. The grain that is in contact with the pushing surface 62a of the mold sorting body 62 is pushed to the swinging side 15c together with the pushing surface 62a (the grain also contacts a portion other than the pushing surface 62a on the swing sorting plate 15). However, the movement of the grain is omitted to simplify the movement of the grain.)

Next, at the moment when the grain returns to the swinging side 15d from the forward movement to the swinging side 15c, the grain that has moved to the swinging side 15c in contact with the pushing surface 62a is moved by the inertia force.
5c. Next, the released kernel is shaken up 1
5c, move upward to the grain layer surface side while moving up and down along the ascending guide surface 62c of the convex sorter 62 and then the plate surface is inclined to the discharge side 15b. Flows down to the discharge side 15b. With this upward movement, it rises to the surface of the grain layer with a small thickness, but does not rise to the surface of the grain layer with a large thickness.

However, when the grain layer thickness is large, the paddy rises to the surface of the brown rice layer while being affected by the difference in specific gravity from the brown rice, while repeating such a rising movement phenomenon several times. It is presumed that the paddy flows down the surface of the brown rice layer along the inclined surface to the lower side 15d by gravity, and the rice and the brown rice are separated. Also, looking at the distribution of the grain layer thickness on the oscillating sorter plate 15, the mixed side is thicker on the supply side 15a where the mixed rice is supplied, and is gradually diffused by the oscillating motion and moves to the discharge side 15d. It is getting thinner.

As described above, the height of the pushing surface 62a of the convex sorter 62 is increased on the supply side 15a in accordance with the change in the grain layer thickness from the supply side 15a to the discharge side 15b.
If it is configured low on the discharge side 15b, the paddy submerged in the lower layer of the thick mixed rice layer on the supply side 15a can be quickly ascended to the surface of the grain layer, and the brown rice submerged in the lower layer is often shaken. It can be moved to the upper side 15c, and the sorting efficiency can be improved. Therefore, as compared with the conventional apparatus, if the efficiency is the same, the surface area of the plate can be reduced, and the efficiency of the surface of the same size can be improved, and the paddy can quickly float on the surface of the brown rice layer. And the flow of the paddy to the shaking side 15d is increased, and the distribution width of the brown rice is increased, and the sorting efficiency can be improved.

Next, another embodiment of the selection unevenness shape of the swing selection plate 15 will be described with reference to FIGS. 9 and 10. FIG.
FIG. 10 shows the concavo-convex shape of the conventional rocking sorter plate 15, and typical shapes thereof are shown in (1) to (3). (1) shows a plan view and a cross-sectional view of Plan A. In the plan A, the selection convex portions a are arranged in a zigzag pattern. The sorting convex portion a is formed by an upper flat surface a2 and an upper flat surface a2 which are connected to the upper end edge of the pressing surface a1, the pressing surface a1, and the upper end edge of the pressing surface a1, which rises at an angle of about right angle to about 70 degrees from the plate surface. Ascending guide surface a3, which is connected to the edge of the lower side 15d with a downward slope, supply side guide surface a4, which is connected to the edge of the supply side 15a of the upper flat surface a2 with a downward slope, and upper flat surface a2.
And a discharge side guide surface a5 connected to the end edge of the discharge side 15b at a downward inclination.

(2) shows a plan view and a sectional view of the plan B. In the plan B, a large number of sorting concave portions b are arranged in a staggered manner. The sorting recess b has a pushing surface b1, which is depressed at a substantially right angle from the plate surface, a bottom flat surface b2, which is connected to a swinging upper surface 15c from a lower edge of the pushing surface b1, and a swinging upper surface 15c edge of the bottom flat surface b2. Guide surface b3, which is connected to the supply side 15a of the bottom flat surface b2 at the ascending slope.
And a discharge side guide surface b5 which is connected to the end edge of the discharge side 15d at an upward slope.

(3) shows a plan view and a sectional view of the C plan. In the C plan, a large number of selection concave portions c are arranged in a staggered manner. The sorting recess c is formed by a pushing surface c1 which is depressed substantially at a right angle from the plate surface, a bottom flat surface c2 connected to a swinging upper surface 15c from a lower edge of the pushing surface c1, and a swinging upper edge 15c edge of a bottom flat surface c2. Guide surface c3, which is connected to the supply side 15a of the bottom flat surface c2 at the ascending slope, and the supply side guide surface c4, which is connected at the ascend slope to the bottom flat surface c2.
And a discharge-side guide surface c5 connected to the end edge of the discharge-side 15d at an ascending inclination.

In these conventional apparatuses, the swinging sorting plate sorts mixed rice while reciprocating and swinging obliquely up and down in the direction of the swinging side 15d from the swinging side 15d. As shown in the figure, the brown rice g and the rice m
1 tends to be supported and pushed in the lateral direction, and receives much resistance of the upper grain when moving to the swinging side 15c (compared to the one pushed vertically). There is a problem in that since there is a tendency and the upper flat surface a2 is configured, the area of the selection convex portion a becomes large, a large number of the selection projections a cannot be arranged on the plate surface, and the selection efficiency does not increase. Was.

In the case of plan B, as shown in the figure,
Since the brown rice g tends to fit into the bottom flat surface b2 in the vertical direction, the pushed brown rice g smoothly moves upward and downward, but it is difficult for two grains to vertically enter one bottom flat surface b2,
Even if two grains are contained, brown rice g on the rocking side is weakly pushed to the rocking side, and there is a problem that efficiency is not sufficiently improved.

In the case of the plan C, as shown in the figure,
Brown rice g tends to fit in the bottom flat surface c2 in the lateral direction, and the pushed-in brown rice g is difficult to move smoothly to the upper side,
Two grains of brown rice g hardly enter into one bottom flat surface c2, and even if it does, brown rice g on the rocking side is weakly pushed to the rocking side, and there is a problem that the sorting efficiency is not sufficient.

In this embodiment, the following configuration is adopted. A large number of sorting ridges 63 are arranged on the swing sorting plate 15 along the vertical direction of grain flow. The sorting ridge 63 is connected to the long pushing surface 63a in the grain flowing direction for pushing the grain to the swinging upper side 15c, and to the upper end edge of the long pushing surface 63a in the downward swinging side 15d in a downward slope. And a rising guide surface 63b that is long in the downstream direction and guides the grains from the lower side 15d upward to the swinging upper side 15c. When arranging the sorting ridges 63, 63,... On the plate surface, the rising guide surface 63b of the sorting ridge 63 located on the swinging side 15c.
In the case of mixed rice sorting, a small brown rice g having a large specific gravity is applied to the surface of the inclined lower edge and the pushing surface 63a of the sorting ridge 63 positioned adjacent to the swinging side 15d. A large paddy with a length substantially in the short axis direction when placed on
Is shorter than the length in the minor axis direction.

Then, the height of the pushing surface 63a is set to be slightly higher than the vertical center of gravity (1/2 of the height) of the height of the small brown rice g placed on the plate surface. As a configuration in which the paddy m is configured to be lower than the center of gravity of the height placed on the plate surface in the vertical direction, the pushing of the brown rice g to the swinging upper side 15c is promoted, and the pushing of the rice m to the swinging upper side 15c is suppressed. I have. In addition,
In forming the sorting ridge 63, a configuration may be adopted in which the pushing surface 63a is higher near the supply side 15a and is gradually or gradually lowered toward the discharge side 15b.

Next, the operation of the above embodiment will be described. When the mixed rice is sorted by reciprocatingly swinging the swinging sorting plate 15 in the W direction, as a primary phenomenon, small brown rice g having a large specific gravity is obtained.
Settles in the lower layer, and large-sized paddy with low specific gravity floats in the upper layer. Next, as a secondary phenomenon, brown rice g that settled in the lower layer
As shown in FIG. 9 (3), the pushing surface 6 of the sorting ridge 63
3a, it tends to be contacted and supported along the lateral direction, and is pushed along with the forward movement of the pushing surface 63a to the swinging upper side 15c, and moves to the swinging upper side 15c (the grains are pushed on the plate surface. The portion other than the portion 63a is also in contact, and moves to the swinging side 15c due to frictional resistance and the like along with the forward movement, but the description of the movement of the grain is omitted for simplification of the description).

Next, as a third phenomenon, the swinging side 15c
At the moment when it returns to the swinging side 15d from the forward movement to
Brown rice g that has been pushed to 3a and moved to the upper side 15c
Is released to the swinging side 15c by inertial force. Then
As a fourth phenomenon, the released brown rice g is pushed onto the pushing surface 63a.
Along the rising guide surface 63b located on the swinging upper side 15c. The paddy rises and rises above the brown rice layer in combination with the upward movement and the specific gravity difference. Further, as the backward movement to the swinging side 15d proceeds, the grains flow down on the plate surface to the discharge side 15b due to the inclination of the plate surface to the discharge side 15b. At this time, as shown in FIG. 9 (3), the brown rice g flows down to the discharge side 15d along the longitudinal direction on the pushing surface 63a, and is sorted while flowing down quickly.

The rice sunk in the lower layer also exhibits the same phenomenon as the brown rice g and rises to the surface of the brown rice layer in combination with the difference in specific gravity from the brown rice g. Then, as a fifth phenomenon, the paddy flows down the brown rice layer surface to the swinging side 15d by gravity along the inclined surface of the plate surface to the swinging side 15d. Thus, the brown rice g is distributed on the rocking side 15c, the paddy is distributed on the rocking side 15d, and the mixed rice is sorted while being distributed in the middle.

As described above, the sorting ridge 63 is constituted by the pushing surface 63a and the rising guide surface 63b which are long in the grain flowing direction and the width in the swinging direction is narrowed. 15 and a long pushing surface 63a and a rising guide surface 63b are formed in the flow direction of the grain, so that the lower layer continuously contacted and supported on the pushing surface 63a in the lateral direction. The brown rice g can be reliably pushed to the swinging side 15c, and then the movement to the swinging side 15c is taken over by the ascending guide surface 63b located at the swinging side 15c, and the movement of the brown rice g to the swinging side 15c is accelerated. By the pushing action of the pushing face 63a and the subsequent rising guide and specific gravity difference of the rising guide face 63b, the paddy submerged in the lower layer can speed up the floating movement to the surface of the brown rice layer and improve the sorting efficiency. .

The height of the pushing surface 63a is set slightly higher than the vertical center of gravity (1/2 of the height) of the height of the small brown rice g placed on the plate surface. Since the configuration was made lower than the vertical center of gravity of the rice h, the pushing of the brown rice g to the rocking side 15c was promoted, and the pushing of the rice m to the rocking side 15c was suppressed. Becomes wider,
The sorting efficiency is improved.

Further, when supplying the mixed rice to the swinging sorting plate 15, the mixed rice is supplied from the swinging upper side 15 c,
Some are supplied from 5d. In this example,
When supplied from the lowering side 15d, the mixed rice supplied to the lowermost side 15d is quickly moved to the upper side 15c by the pushing surface 63a and the ascending guide surface 63b, and is moved to the uppermost side 15c and the uppermost side 15c. Sorting can be started from a place close to
The vertical length of the swing sorting plate 15 can be reduced, and the plate surface can be downsized. In addition, when supplying to the swinging side 15c,
Since the sorting can be started from the position of the uppermost supply side 15a and the uppermost swinging side 15c, the size can be further reduced.
