Description

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

Since a conventional hulling device is provided with a swinging portion, a device is provided that utilizes the swinging motion to remove immature grains. However, there are various problems and nothing is perfect.

For example, there is a problem called clogging.

That is, even if the sieve is attached, the clogging particles will immediately fit tightly into the sorting holes. These clogging particles cannot be removed simply by a slight rubbing action. The conventional method was to apply a brush and scrub together, but this device has a cumbersome structure and cannot be attached to small objects. People hate it because it makes noise.

In this respect, a clogging remover using a rubber roll is cheaper and generates less noise, which is advantageous compared to a brush type.

One of the problems with clogging removers that use rubber rolls is that their performance is not as good as that of brushes.
This can be solved by making the rubber roll more active.

In other words, the present invention has a structure in which brown rice is separated from one side by swinging together with the swinging sorting device on the outside of the brown rice outlet of the swinging sorting device that singly sorts the mixed rice supplied from the huller. In one or more stages of immature grain separation shelves for sorting immature grains while transferring them to the other side, the immature grain separation shelf, an upper screen with immature grain sorting holes drilled in a flat thin iron plate, and a flat thin iron plate. It is formed by a lower net with many square holes perforated therein, a rubber roll interposed between the upper net and the lower net, and the lower net has one of the vertical bars and the horizontal bars curved upward. This is an immature grain separation device in the equipment.

To explain with the drawing, 1 is an elevator for loading unhulled rice, a bucket conveyor is installed inside, and a hopper 2 for loading unhulled rice is provided at the lower part of the elevator 1. 3 is a storage tank, and the drop port of the storage tank 3 is connected to the inlet pipe 5 of the hulling section 4 located at the lower part thereof. 6 is an on-off valve, and 7 is an adjustment screw.
A hulling roll and the like are provided in the hulling section 4. A winnowing section 8 is provided on the side of the hulling section 4. Wind selection part 8
A spiral-shaped wind body is formed inside. Reference numeral 9 denotes a horizontally swinging type sorting device, which is formed by overlapping several stages of sorting plates 10 and horizontally swings in the front and back direction. The sorting plate 10 has a substantially rectangular planar shape and is surrounded by a front wall 11, a rear wall 12, a right wall 13, and a left wall 14, and the front side of the right wall 13 is cut out to form a brown rice outlet 15.
The rear side of the left wall 14 is cut out to form an unhulled rice outlet 16, and on the plate surface of the sorting plate 10 from the rear wall 12 is an unhulled rice transfer projection 1 that is inclined in the direction of the unhulled rice outlet 16.
7 is formed on the entire surface, and the outside part, that is, the sorting plate 1
A brown rice transfer protrusion 18 inclined in the direction of a brown rice outlet 15 is formed on the entire surface of the portion closer to the front wall 11 of the rice cooker. Reference numeral 19 denotes a brown rice transfer section that guides the brown rice taken out from the brown rice outlet 15 to the hopper 21 of the finished rice elevator 20 and separates the brown rice from immature grains. In the brown rice transfer section 19, immature grain sorting devices are provided in two stages, upper and lower, depending on the case. 22 is an upper immature grain separation shelf, and 23 is a lower immature grain separation shelf. Both the immature grain separation shelf 22 and the immature grain separation shelf 23 have an upper screen 25 in which immature grain sorting holes 44 are drilled in a flat thin iron plate, a lower screen 24 in which a large number of square holes 47 are bored in a flat thin iron plate, and an upper screen 25. and a rubber ball 26 interposed between the bottom screen 24 and the bottom screen 24. The lower net 24 is formed by curving one of the vertical bars 45 and 46 upward so that the rubber balls 26 can move sufficiently. Reference numerals 27 and 28 indicate insertion ports opened on the side of the brown rice transfer section 19, and when inserted from the side by holding the handles 29 and 30 formed on the immature grain separation shelves 22 and 23, the slots shown in FIGS. 2 and 3 are inserted. It is installed like this.

A bottom plate 31 receives the immature grains screened by the immature grain separation shelf 22, and is formed to become lower toward the hopper 21. 32 is a bottom plate that receives the immature grains sieved by the immature grain separation shelf 23;
A large number of protrusions 33 (the same may be applied to the bottom plate 31) are formed on the bottom plate 32 to move the immature grains in the direction of the immature grain outlet 34. 35 is a drop port for the bottom plate 31, and 36 is a port from the drop port 35 to the bottom plate 32.
It is a guide channel leading to.

The immature grain separation shelf 22 and the immature grain separation shelf 23 are installed in a completely parallel state, and the supply side 3
7 is provided with four distribution ports 38 leading to the immature grain separation shelf 22 and four distribution ports 39 leading to the immature grain separation shelf 23 every other time. 40 is a level transfer shelf provided outside the brown rice outlet 15, the hopper 21 side is formed high, and numerous transfer protrusions 41 are formed on the plate surface.
The lower side faces the distribution ports 38 and 39. In the figure, 42 is a paddy/rice return trough, and 43 is a storage tank.

Next, we will discuss the effect.

When unhulled rice is supplied to the husking hopper 2, the unhulled rice rises inside the husking elevator 1 and is temporarily stored in the storage tank 3, and then flows down inside the inlet tube 5 depending on the degree of opening of the on-off valve 6 and reaches the hulling section. 4, where the rice is hulled. The hulled grains are wind-selected in the wind-selecting section 8 and supplied to the sorting plates 10 at each stage. On the horizontally swinging sorting plate 10, the unhulled rice transfer protrusion 17 and the brown rice transfer protrusion 18 act as
The whole turns as shown by arrow A, but brown rice with a heavy specific gravity moves toward the front wall 11, and the brown rice transfer protrusion 1 moves toward the front wall 11.
8, it moves toward the brown rice outlet 15 as shown by the arrow B, and falls down the leveling transfer shelf 40 from the brown rice outlet 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 channel 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 Figure 2.
four distribution ports 38 formed on the supply side 37;
It is divided into four parts by the distribution port 39, and there are two distribution ports 38.
Those flowing into the two distribution ports 39 are combined and supplied to the upper immature grain separation shelf 22, and those flowing into the two distribution ports 39 are combined and supplied to the lower immature grain separation shelf 23. Therefore, the brown rice is divided into two halves almost exactly and supplied to the upper and lower immature grain separation shelves 22 and 23, and the brown rice
5, taken out onto the bottom plate 31, and supplied onto the bottom plate 32 from the drop port 35 of the bottom plate 31 via the guide gutter 36. The brown rice supplied to the immature grain separation rack 23 is sieved by the upper screen 25 of the immature grain separation rack 23, and the immature grains are taken out to the bottom plate 32.

During this time, immature rice constantly sticks into the immature grain sorting hole 44 and blocks the immature grain sorting hole 44;
The lower screen 24 of the present invention has a shape in which a large number of square holes 47 are punched in a flat thin iron plate, and one of the vertical bars 45 and the horizontal bars 46 is curved upward. The ball 26 moves violently and completely removes the clogged grains.

The brown rice sorted by the sorting plates 10 on each stage is separated into two stages, the upper and lower immature grain separation racks 22 and the immature grain separation rack 2.
3 in parallel and subjected to sorting action, the grain layers supplied to the immature grain separation rack 22 and the immature grain separation rack 23 are thinly distributed and eventually separated completely. The separated brown rice is supplied from the hopper 21 to the finished rice elevator 20 and stored in the storage tank 43.

The present invention is based on a brown rice outlet 1 of a swing type sorting device 9 that swings and sorts heterogeneous mixed rice supplied from a hulling section 4.
5, in which an immature grain separation shelf 22 is provided in one or more stages for separating immature grains while swinging together with the rocking type sorting device 9 to transfer the unripe grains from one side to the other. The grain separation shelf 22 has an upper screen 25 in which immature grain sorting holes 44 are bored in a flat thin iron plate.
A lower screen 2 with many square holes 47 punched in a flat thin iron plate.
