Abstract

PURPOSE:To decrease the sepn. load in an unhusked rice winnowing path and to improve sepn. performance by previously removing the light chaff, dust, etc., as a part of the husked rice by a dust sucking and discharging machine, supplying the remaining husked rice onto a husked rice transfer rack and subjecting the husked rice to winnowing. CONSTITUTION:The husked rice subjected to husking by a pair of husking rolls 7, 7 is husked toward a backward reflection plate 17 and the light chaff, etc., as a part of the husked rice are guided backward to an upper side along the slope of the reflection plate 17. The husked rice is sucked and discharged through the upper part of a main sepn. wind path 12 by an upper dust sucking and discharging mechanism 11. The remaining heavy mixed rice and barnyard millet, etc., of the husked rice are dropped along the slope of the reflection plate 17 and are supplied to the sepn. beginning end side of the husked rice transfer rack 14. Part thereof is dropped and supplied from above the reflection plate 17 onto the husked rice transfer rack 14 through the main sepn. wind path 12. The unhulled rice, unpolished rice, barnyard millet, etc., dropped in such a manner onto the husked rice transfer rack 14 are separated to the light chaff, dust, etc., and the heavy unhulled rice, unpolished rice and barnyard millet while these chaff, etc., are sent to the terminal side under oscillation on the husked rice transfer rack 14.

Can be located above the gear box 37,
It can be lifted up from the oil and the gearbox 37
It is possible to prevent oil from leaking.

Next, another embodiment of the mixed rice fried machine 4 will be described with reference to FIG. This mixed rice fried machine 4 is a bucket fried type, and the upper and lower ends of the fried case 35 are
Each of the fried rollers 36, 36 is pivotally supported. This fried grain roller 36 has roller portions 3 on both left and right end portions of the shaft portion 36a.
This is a form in which 6b and 36b are provided. This fried roller 36
A pair of left and right belts 38, 38 to which buckets 37, 37, ... Are attached are wound around the roller portions 36, 36 of FIG. The bucket 37 is attached so as to be positioned on the inner peripheral side with respect to the belts 38, 38, and when the buckets 37, 37, ... Rotate the portions of the upper and lower fried rollers 36, 36. The inner diameter side of the fried grain rollers 36, 36 is rotated. Therefore, the fried food case 35 can be configured to be close to the belt 38 and the outer peripheral surface of the belt 38 which are wound inside, and the size can be reduced.

Next, the transmission relationship of the hulling / sorting machine will be described with reference to FIG. The drive pulley 39 of the main motor 15 is
It is transmitted to the hulling pulley 41 via the transmission belt 40,
One of the hulling rolls 7 is driven. Paddy-
The power is transmitted from the reel 41 to the other hulling roll 7 via a hulling gear transmission device (not shown) composed of gears or the like. Small diameter pulley 4 that rotates integrally with the hulling pulley 41
2 and the pulley 4 attached to the transfer spiral 16a.
A transmission belt 46 is wound around the dust collecting pulley 3, the dust collecting pulley 44, and the intermediate pulley 45, and is transmitted to each of them. A swinging pulley 47 that rotates integrally with the intermediate pulley 45.
And the pulley 48 and the pulley 49 are respectively wrapped around the rocking transmission belts 50 and 51, and the rocking device of the rocking sorting device 21 and the sliding rice transfer shelf 14 are wound. Rocking device 18
Are driven by each other. In this way, since the power is transmitted from the rocking pulley 47 that drives the rocking device of the rocking sorting device 21 to the sliding-out rice transfer shelf 14, the rocking rotation speed is set to a relevant rocking rotation speed. Therefore, the transfer of the discharged rice from the discharged rice transfer shelf 14 can be smoothly performed.

Next, the operation of the embodiment shown in FIGS. 1 and 2 will be described. When performing a hulling / sorting operation, the rotating parts of the machine body are driven, the paddy is loaded into the paddy hopper 8, and the paddy is supplied to the paddy rolls 7 and 7 through the paddy supply passage 8a. Then, the paddy is hulled by a pair of upper and lower hulling rolls 7, 7 which are rotating in opposite directions, and the slid rice is slid toward the reflecting plate 17 at the rear and collides with the hull. Then, some of the light rice husks are guided to the upper rear side along the inclined surface of the reflection plate 17, flow through the main sorting air passage 12 to the suction dust collector 11, and are discharged to the outside of the machine through the dust pipe 34. It The remaining heavy mixed rice and rice cake flow down to the lower part of the reflection plate 17, or fall from the upper part of the reflection plate 17 through the main sorting air passage 12 to the starting end of the slide-out rice transfer rack 14. Next, the discharged rice is transferred to the discharged rice transfer shelf 14
While being swung up, it is sent to the end side, during which light rice husks and dusts are sucked by suction air, flow through the main sorting air passage 12 to the suction duster 11, and are discharged to the outside of the machine. In addition, heavy paddy, brown rice, and rice grains are dropped from the end side of the slide-out rice transfer rack 14 to the slide-out rice receiving trough 16 and are selected.

Next, the extruded rice selected in the extruded rice receiving gutter 16 is transferred by the transfer spiral 16a and then the mixed rice lifting machine 4
Is fed to the rocking sorting plates 22, 22, ... After passing through the mixed rice hopper 20, the distribution / supply gutter 23, and the distribution case 24. The mixed rice supplied to the rocking sorting plates 22, 22, ...
The brown rice is sorted by the size of the grain shape, the size of the specific gravity, or the difference in frictional resistance by the reciprocal rocking in the horizontal slanting direction. Then, after passing through the brown rice gutter 27 and the brown rice flow path 28, it is taken out of the machine by the brown rice lifting machine 5. Further, the mixed rice which is unevenly distributed in the lateral middle portion of the swing selection plates 22, 22, ... Is separated by the brown rice partition slope 25 and the paddy partition slope 26 and taken out, and the mixed rice receiving trough 29, the mixed rice flow path. 30, shaken rice receiving gutter 16, mixed rice lifting machine 4, mixed rice hopper 20, distribution supply gutter 23, distribution case 24, and rocking sorting plates 22, 22,
It is supplied to and re-sorted. In addition, the swing selection plate 22,
The non-uniformly distributed paddy on the lateral rocking side of 22, ... Is separated by the paddy partitioning slope 26 and taken out, and the paddy receiving trough 31 and the paddy channel 3 are taken out.
2. After passing through the grain hulling machine 33, the grain is reduced to the grain hull rolls 7, 7 and again grained.

[0020]

Since the present invention is constructed as described above, a pair of hulling rolls 7, which are vertically opposed to each other,
The paddy rice hulled in 7 is collided and guided by the rearwardly inclined plate 17 of the reflecting plate 17, and a part of the light rice husks of the paddy rice is rearward and upward along the inclined face of the reflecting plate 17. Guided by
It is sucked by the suction dust collector 11 above through the main sorting air passage 12 and discharged to the outside of the machine, and the heavy paddy, brown rice, and rice cakes remaining from the removed rice are supplied to the removed rice transfer rack 14. Therefore, the sorting load on the slide-out rice transfer shelf 14 can be reduced and the sorting efficiency can be improved.
