Description

[Detailed Description of the Invention] The present invention relates to a rice-hulling plant, which is composed of only two elevators: a stake-in elevator and a rice-milling elevator, and does not have a vertically movable storage tank. It is characterized by being inexpensive and easy to handle.

The conventionally known rice hulling rice milling plan i. uses at least three elevators and a storage tank that moves downward in response to the storage volume.

That is, a. A unloading machine for loading which supplies unhulled rice as a raw material to a coarse sorter b. A unloading machine for rice milling from a rocking type mixed rice sorting device to a rice polishing machine C1 A rocking mixed rice sorting device from a huller A mixed rice supply elevator is required to supply the mixed rice to the container, and a storage tank that moves up and down according to the storage amount is installed at the discharge part of the mixed rice supply elevator (=J
There it was.

The reason is that the conventional oscillating mixed rice sorting device does not separate the four types of rice into only two types, paddy rice and brown rice.
The rice is divided into three types: unhulled rice, brown rice, and mixed medium-t111 rice.The intermediate rice is returned to the sorting device for sorting, so depending on how the intermediate rice is returned, the sorting device may exceed the amount. Therefore, when a large amount of intermediate rice is returned, it is necessary to automatically adjust the amount of hulling to decrease. Therefore, an elevator for supplying mixed rice and a vertically movable storage tank for automatically adjusting the amount of hulling are required. It needed a tank.

However, by combining the various parts as follows, it is possible to reduce the conventionally required three elevators to two, and to obtain a rice-hulling device that does not require a freely movable storage tank. I can do it.

Explaining with example diagrams, Figure 1 is a side view of the entire assembly. Figure 2 is a perspective view of the coarse sorter; Figure 3 is a longitudinal side view of the coarse sorter; Figure 4 is a vertical side view of the rice grain sorting section. Figure 5 is a longitudinal cross-sectional side view of the swinging sorting section. Figure 6 is a plan view of the sorting plate, and FIG. 7 is a cross-sectional view of the rice milling machine.

A coarse sorter 3 is installed near the. The structure of the rough separator 3 is that the lower part is formed into a frame part 4, the upper part is formed into a sorting part 5, a supply hopper 6 is formed in a part of the shielding part 5, and a swinging part is formed in the waste separating part 5. A frame 7 is provided, a sorting plate 8 with a large number of sorting holes formed in the swinging frame 7 is horizontally installed substantially horizontally, and a chino 9 that can only rotate is placed on both left and right sides of the upper surface of the sorting plate 8. Cheno 9 is sorting section 5
A pair of front and rear sprockets 1.0.11 are pivoted on the
The cheno 9.9 on both the left and right sides has horizontal rods 12 crossed in a direction perpendicular to this, and several claws 13 are attached to the horizontal rods 12. Reference numeral 14 denotes a bottom plate of the swing frame 7, and the bottom plate 14 is formed with a large number of feeding protrusions 14'. 15 is a rocking device, 16 is a diagonal rod, 17 is a foreign object drop port, 1
8 is the port where the paddy and rice fall.

That is, when raw rice is supplied from the supply homper 6,
The unhulled rice flows on the sorting plate 8 and falls in the -1 direction from the sorting hole, and is moved in the direction of the unhulled rice falling port 18 by the feeding protrusion 14 of the bottom plate 14 provided on the lower side of the sorting plate 8. Dust that is taken out from the paddy/rice drop 18 and does not pass through the first sorting hole is scraped out to the foreign matter fall port 17 by the claws 13.

The unhulled rice roughly selected by the rough sorting machine 3 is hulled by a hulling device 19 located above it. There are two types of structures for the hulling device 19, and the first example will be explained with reference to FIG. A wind selection chamber 24 is formed in the lower part. 25 is a blower that sends sorting air to the wind selection room 24;
6 is a mixed rice dropping chamber, 27 is an unripe rice outlet, 28 is a suction blower, 29 is an on-off valve attached to the lower side of the mixed rice dropping chamber 26, 30 is its shaft, and the on-off valve 29 is not shown in the figure. It is not omitted, but is constantly moved upward by a spring, and opens and closes depending on the storage of mixed rice.

The column-type mixed rice sorting device 31 is a swing-type sorting device that can separate the mixed rice falling from the mixed rice falling chamber 26 into only unhulled rice a and brown rice.
It is formed from a distribution device 33 and a horizontal rocking device 34.

As shown in FIG. 6, the sorting plate 32 has a front wall 35, a rear wall 36,
It is formed by a left wall 37 and a right wall 38, and the front part of the left wall 37 is cut out to form a brown rice outlet 39, and the right wall 3
The rear portion of 8 is notched to form a paddy rice outlet 40.

A brown rice transfer protrusion 41 whose tip is inclined toward the brown rice outlet 39 is provided over the entire front part of the plate surface -F of the sorting plate 32. The rear portion is provided with unhulled rice transfer protrusions 42 facing toward the unhulled rice outlet 40 on the entire surface.

Reference numeral 43 is a rice milling elevator that fries the brown rice separated by the swinging type rice sorting device 31 and supplies it to the first rice milling machine 44. It is set up in a crab. White rice t discharged from the second rice mill 45±small rice separator 46':.

After the inflow, the small rice is sorted. The first rice milling machine A44 and the second rice milling machine 45 have the same structure, and a cross section thereof is shown in FIG.

47 is the upper receiving hopper, 48 is the whitening room, whitening room 4
A rice polishing roll 49 that rotates on a vertical axis is installed inside the rice mill 8 . The rice milling roll 49 has a downward feeding spiral 50 in the upper part 1;
Strip-shaped grinding roll pieces 51 and iron friction roll pieces 52 are attached alternately in the circumferential direction to the lower part of the downward feed spiral 50, and the outer periphery of the grinding roll pieces 51 and friction roll pieces 52 is surrounded by a polishing tube 53. . The polishing cylinder 53 is formed so that when the load in the polishing chamber 48 becomes large, it moves downward and automatically widens the lower discharge port. 54 is a discharge section, 5
5 is a bran suction fan, 56 is a charging port 57 of the elevator l, and 58 is a discharge gutter.

Next, we will discuss the effect.

When unhulled rice is put into the loading port 56 of the elevator 1, the unhulled rice moves up the elevator 1, flows into the Japanese translation machine 3 through the discharge gutter 2, and is supplied onto the sorting plate 8 from the supply hopper 6 of the coarse sorter 3. Ru. Since the sorting plate 8 is slightly vibrated by the rotation of the rocking device '15, the grains pass through the sorting holes of the sorting plate 8 and fall onto the bottom plate 14, and only foreign substances such as straw waste, wood chips, and stone blocks are sorted out. Board 8”-
remains in The foreign matter on the second sorting plate 8 is swept out by the claws 13 that move on the sorting plate 8 by the rotation of the checker 79 and falls from the foreign matter fall port 17, and the grains that have passed through the sorting plate 8 are swept out by the claws 13 that move on the sorting plate 8 through the rotation of the checker 79.
1 is moved and supplied to the supply tube 20 of the hulling device 19 from the unhulled rice drop port 18.

The unhulled rice a supplied to the supply tube 20 is fed little by little to the rubber roll 23 by the feeding roll 22, where it is hulled and falls into the winnowing chamber 24. Since the wind from the blower 25 is blowing in the wind selection chamber 24, the light rice husks C are blown away and removed by suction by the suction blower 28. At this time, if the specific gravity is relatively small, the ice is removed. 7 and is taken out, and the brown rice with a relatively large specific gravity and the unhulled rice A are removed.
The mixed rice is stored in the mixed rice falling chamber 26, and the on-off valve 29 is pushed down according to the stored amount, and the mixed rice falls into the distribution device 33 through the gap between the on-off valves 29.

The materials falling on the distribution device 33 gradually flow downward due to the swinging motion, and are distributed and supplied to the sorting plates 32 at each stage from the distribution port formed at the terminal end. The sorting plate 32 has a structure 7 as shown in FIG. The brown rice is removed by moving in the direction of the brown rice removal r139 as shown by arrow B, and flows into the loading port 57. The unhulled rice a is moved in the direction of the unhulled rice take-out port 40 as shown by the arrow C by the action of the unhulled rice transfer protrusion 42, is taken out, is returned to the tensioning hole 1'' 56, and is circulated again.
The brown rice that has flowed into No. 7 rises through the elevator 43 and flows into the receiving hopper 47 of the rice milling machine 44 through the discharge gutter 58. The brown rice that has entered the receiving hopper 47 of the first rice milling machine 44 flows into the milling room 48, is sent downward by the action of the rice milling rolls 49, and is polished by the grinding roll piece 51 and the friction roll piece 52, and the rice is polished by the grinding roll piece 51 and the friction roll piece 52. 54, and the second rice mill 45
The rice flows into I'T IW and is milled. During this time, the bran is ejected from the polishing tube 53 and removed by suction by the bran suction fan 55.

The white rice flowing out from the discharge section 54 of the second rice milling machine 45 flows into the small rice separator 46 and is separated into good rice and waste rice.

As already mentioned, a known rice hulling rice milling plant includes a rice-polishing tool 1 (four machines) for supplying the raw material, unhulled rice, to a coarse sorter, a rice milling elevator that extends from a rocking mixed rice sorting device to a rice milling machine, A mixed rice supply elevator is required to supply the mixed rice from the huller to the oscillating mixed rice sorting device, and the discharge section of the mixed rice supply elevator is equipped with a A storage tank was installed. In other words, the conventional swing-type mixed rice sorting device does not separate mixed rice into only two types, 86 paddy rice and brown rice, but separates it into three types: hulled rice, brown rice, and 4) intermediate rice in the u-coated state. Since the intermediate rice is sent back to the above-mentioned sorting device for sorting, depending on how the intermediate rice is returned, the sorting device may overstep its feet and become unable to be sorted. It became necessary to automatically adjust the amount of paddy to decrease, and therefore, a lifting machine for supplying mixed rice and a storage tank with a freely movable top for automatically adjusting the amount of hulling were required. A rice graining machine 1, a roughing machine 3 installed at two positions, a hulling device 19 installed at a lower position of the roughing machine 3, and a hulling device 1
Swinging type: g combined rice sorting device 31 installed at the lower position of 9
, a rice milling elevator 43 that lifts the brown rice flowing out from the sorting device 31, a first rice milling machine 44 that mills the brown rice flowing out from the rice milling elevator 43, and a second rice milling machine 44 provided below the first rice milling machine 44. It consists of a rice polishing machine 45 and a rice separation device 46 installed below the second rice polishing machine 45, and the swinging mixed rice sorting device 31 is a huller that separates the mixed rice into two types: paddy rice a and brown rice. Because it is a rice milling plant, there is no need for a mixed rice supply elevator to feed mixed rice from the huller to the swinging mixed rice sorting device, and instead of three elevators, the number of elevators used can be reduced to two. Therefore, it is possible to obtain a rice hulling and rice milling device that does not require a vertically movable storage tank.
