Description

[Detailed Description of the Invention] The present invention has an immature grain separation device integrally attached to the hulling device.

With the structure of the conventionally known hulling device, it was not possible to remove immature rice to the extent that it could be packed into bags no matter how it was operated, so a measuring bagging device was not directly attached to the hulling device. Previously, a separate rice sorting machine called a rice grader was attached to the hulling device, and a weighing and bagging device was connected to the discharge side of the rice grader.

However, if a special immature grain removal net is attached to the swing-type sorting device of the huller, it becomes possible to remove immature grains to the extent that they can be weighed and packed into bags. The rate at which immature rice is sorted and removed can also be adjusted by simply replacing the net.

That is, the present invention is a device that sorts the mixed rice supplied from the hulling section by swinging a sorting plate back and forth, and a brown rice transport section is integrally provided at the brown rice outlet of the sorting plate to transport the unripe rice from one side to the other in the back and forth direction along the sorting plate, and sorts the immature rice.
The brown rice transport section is fitted with an immature rice sorting shelf of integral structure having an upper and lower screen and balls slidably attached between them, which is immovable in the front-to-back direction but can be freely inserted and removed in the left-to-right direction relative to the grain flow direction, forming an immature grain separation device in a rice huller.

The lower screen 24 is a ball 26 holder that makes the balls jump, and is made of a large-mesh screen, and when the balls 26 come into contact with the lower surface of the upper screen 25, it removes grains and the like that are stuck in the upper screen 25, thereby clogging the upper screen 25. prevent. A bottom plate 31 receives the immature rice sieved by the immature rice separation shelf 22, and is formed to become lower toward the hopper 21. Numeral 32 is a bottom plate that receives the immature rice sieved by the immature rice separation rack 23. On the bottom plate 32, a large number of protrusions 33 (the same may be done for the bottom plate 31) are formed, and the immature grain outlet 34 is Move the immature grains in the direction. Reference numeral 35 indicates a drop port for the bottom plate 31, and 36 indicates a guide gutter leading from the drop port 35 to the bottom plate 32.

The unripe rice separation rack 22 and the immature rice separation rack 23 are installed in a completely parallel state, and the supply side 3

Reference numeral 0 denotes a level transfer shelf provided outside the brown rice outlet 15, which is higher on the hopper 21 side, and has numerous transfer protrusions 41 formed on its plate surface.

In the figure, 42 is a paddy/rice return trough, and 43 is a storage tank.

Next, we will discuss the effect.

Before starting the work, the unripe rice separating shelves 22 and 23 with a mesh width of, for example, 1.8 mm are inserted into the insertion ports 27 and 28, the presser fittings 45 are brought into contact, and the screws 46 are tightened. In this state, when unhulled rice is supplied to the tensioning hopper 2, the unhulled rice rises inside the tensioning elevator 1, is temporarily stored in the storage tank, and flows down inside the inflow tube 5 depending on the opening/closing degree of the on-off valve 6. It flows into the hulling section 4 and is hulled. The hulled grains are wind sorted in the wind sorting section 8 and supplied to the sorting plates 10 at each stage. On the horizontally swinging sorting plate 10, there are a paddy rice transfer protrusion 17 and a brown rice transfer protrusion 1.
8, the whole rotates as shown by arrow A, but brown rice with a heavy specific gravity moves toward the front wall 11, and due to the action of brown rice transfer protrusion 18, it heads toward brown rice outlet 15 as shown by arrow B. The brown rice is moved and dropped down the leveling transfer shelf 40 from the unloading port 15. The unhulled rice, which has a light specific gravity, moves in the direction of the arrow C and falls from the unhulled rice outlet 16 into the unhulled rice return gutter 42. The brown rice that has fallen onto the leveling transfer rack 40 gradually flows down toward the lower supply side 37 as shown in Fig. 2, and some of it is transferred to the upper stage through the distribution ports 38 and 39 formed on the supply side 37. The remaining unripe rice is supplied to the unripe rice separation rack 22 located at the lower stage, and the remaining part is supplied to the lower immature rice separation rack 23. The brown rice supplied to the unripe rice separation rack 22 is sieved by the above-mentioned upper screen 25 with a mesh width of 1.8 mm, taken out to the bottom plate 31, and passed through the drop port 35 of the bottom plate 31.
It is supplied onto the bottom plate 32 via the guide gutter 36. The brown rice supplied to the unripe rice separation rack 23 is
Immature rice is sieved through an upper screen 25 with a mesh width of 1.8 mm, and the unripe rice is sieved on the bottom plate 3.
It is taken out in 2.

That is, the brown rice sorted by the sorting plates 10 on each stage is transferred to the upper and lower two stages of unripe rice separation racks 22 and immature rice separation racks 23.
Since the grains are fed in parallel to each other and subjected to a sorting action, the grain layer supplied to the immature rice separation rack 22 and the immature rice separation rack 23 is thinly distributed. The separated brown rice is supplied from the hopper 21 to the finished rice elevator 20 and stored in the storage tank 43.
is stored in However, if the quality of the raw material to be supplied changes, the thickness of the immature rice will also change, so loosen the screw 46, remove the presser metal fitting 45, replace the immature rice separation racks 22 and 23, and continue do the work.

With the structure of conventionally known hulling equipment, it is not possible to remove immature rice to the extent that it can be packed into bags no matter how it is operated, so a measuring bagging device is not directly attached to the hulling equipment, A separate rice sorting machine called a rice grader was attached to the hulling device, and a weighing and bagging device was connected to the discharge side of the rice sorting machine.

However, in the present invention, the mixed rice of different types supplied from the huller is sorted by swinging the sorting plate in the front and back direction, and the brown rice outlet of the sorting plate is moved from one side to the other side along the sorting plate. A brown rice transfer section for sorting immature rice while being transferred in a direction is integrally provided. The gist of this is an immature grain separation device in a hulling device that has an immovable structure in the front-rear direction but is detachable in the left-right direction with respect to the direction of grain flow, so it is possible to separate immature grains with different grain widths. Sorting shelf 2
Just by inserting 2 and 23, you can sort as you wish. In addition, the immature rice sorting shelves 22 and 23 have an immovable structure in the front-rear direction, and are removable in the left-right direction. There is little rattling, and therefore, not only can the sorting device be made quiet, but also the presser metal fitting 45 and the screw 46 can be used with a simple device.
