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 conventionally known hulling equipment, it is not possible to remove immature grains to the extent that they can be packed into bags, no matter how you operate them. 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, 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.

In other words, if the brown rice transfer section is oscillated horizontally to reduce the jumping of the rice grains, the brown rice will be in contact with the sorting net for a long time, and the immature grains contained in the rice grains will be sieved out during that time. . Therefore, it is possible to almost completely screen out immature grains without installing a device such as a rice grader.

However, the larger the area of the brown rice transfer section is, the greater the wide almost immature grain sorting effect will be.In order to increase the area, it is conceivable to form the brown rice transfer section in multiple stages above and below. In this way, when the brown rice transfer section is arranged in multiple stages above and below, it is necessary to accurately divide the brown rice taken out from the brown rice outlet into two or three equal parts. In order to divide the brown rice into two equal parts, the supply section is provided with inlets as many as the number of brown rice transfer sections.

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 tube 5 of the hulling section 4 located below. 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. A spiral wind cylinder is formed inside the wind selection section 8, and 9 is 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.

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. Inside the brown rice transfer section 19, immature grain sorting devices are provided in two stages, upper and lower. 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 are formed of a lower screen 24 and an upper screen 25, and balls 26 are stored therebetween. Reference numerals 27 and 28 are outlets opened on the side of the brown rice transfer section 19, and the immature grain separation shelves 22 and 23
By holding the handles 29 and 30 formed on the sides and inserting it from the side, it is installed as shown in FIGS. 2 and 3. The lower net 24 is a receiver for 26 balls to be made to jump,
It is formed of a large-mesh mesh, and when the balls 26 come into contact with the lower surface of the upper mesh 25, the rice clogged in the upper mesh 25 is removed and clogging is prevented. 31
is a bottom plate that receives the immature grains sieved by the immature grain separation shelf 22, and is formed to become lower as it reaches the direction of the hopper 21. 32 is immature grain separation shelf 2
The bottom plate receives the immature grains sieved by the bottom plate 3.
A large number of protrusions 33 (the bottom plate 31 may also be formed in the same manner) are formed on the top of the immature grain outlet 3.
Move the immature grains in direction 4. 35 is the bottom plate 31
The drop port 36 is a guide gutter leading from the drop port 35 to the bottom plate 32.

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.

That is, the brown rice sorted by the sorting plates 10 on each stage is transferred to the upper and lower immature grain separation shelves 22 and immature grain separation racks 23.
Since the grains are fed in parallel to each other and subjected to a sorting action, the grain layers supplied to the immature grain separation rack 22 and the immature grain separation rack 23 are thinly distributed and are then completely separated.
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 a swing-type sorting device 9 that horizontally swings and swings the mixed rice supplied from the hulling section 4.
The swing type sorting device 9 is installed outside the brown rice outlet 15 of the
and an immature grain separation shelf 22 that shakes horizontally to separate immature grains while transferring the brown rice from one side to the other.
