Description

[Detailed explanation of the invention] (a) Industrial application field This invention consists of a separating section, a wind sorting section, and a sorting barrel that is rotatably hung horizontally by forming a large number of pot holes on the inner circumferential surface. This rice hulling machine consists of a pothole-type sorting section that is constructed by inserting a receiving gutter horizontally, and if it detects that foreign matter is mixed in the mixed rice of brown rice and paddy after deairing and sorting, it immediately removes the rice. This invention relates to a rice scraping spout for a grain lifting machine for a rice huller that removes foreign matter from the machine.

(b) Conventional technology As mentioned above, a rice huller is used in which a mixture of brown rice and paddy after deairing is lifted up by a grain lifting machine and fed to a pothole type sorting section to be sorted into brown rice and paddy. A conventional technique for passing the mixed rice through a sieve before feeding it into the sorting barrel of the pot-hole type sorting section is as disclosed in Japanese Patent Application Laid-open No. 59-213481, for example. The structure is as follows.

That is, according to the configuration disclosed in this publication,
The sieve part is configured in the feed gutter that receives the mixed rice flowing into the supply side of the sorting barrel and guides it down into the sorting barrel, and the mixed rice with a high rejection rate is placed at the starting end of the sorting barrel, and the rice is separated from the paddy. This is intended to improve the sorting effect of the pothole by supplying a large amount of mixed rice after this starting point.

(c) Problems to be solved by the invention In the conventional method as described above, a sieve is placed in the feed gutter that receives the mixed rice flowing into the feed side of the sieve or sorting barrel and guides it down into the sorting barrel. This constitutes the sieving part, and feeds the mixed rice with a high rejection rate to the starting end of the sorting barrel, and the mixed rice with a large amount of paddy to the starting end and beyond. The aim of the present invention is to provide a sieve capable of removing foreign matter mixed into rice, so that when foreign matter is mixed into mixed rice, the foreign matter can be easily removed.

Conventionally, each part of the hulling machine, which consists of a dehulling section, wind sorting section, and pothole type sorting section, is constructed in a nearly hermetic manner, making it difficult to prevent foreign matter from entering the mixed rice. Even if it is detected by the occurrence of an abnormal noise, it is difficult to remove it even if it is difficult to remove it, and it ends up circulating through each part many times.

The present invention makes it possible to easily remove foreign substances mixed into the mixed rice in such cases.

(d) Means for solving the problem The present invention is constructed as follows to facilitate the solution.

In other words, there is a pothole type sorting section consisting of a removal section, a wind sorting section, and a receiving gutter inserted into a sorting barrel that is rotatably hung horizontally with a large number of potholes formed on its inner circumferential surface. A rice hulling machine consisting of a rice huller, which lifts up the mixed rice of brown rice and paddy obtained by the dehulling and passing through the winnowing section by a grain lifting machine, and discharges it from its rice hulling port. In the apparatus for supplying the pot-hole type sorting section, the polished rice outlet is configured to be replaceable with one equipped with a sieve for removing foreign matter mixed into the mixed rice.

(e) Effect Since the present invention is configured as described above, if foreign matter is mixed in the mixed rice and abnormal noise is detected from inside the machine, the operation of the huller is temporarily stopped and the grain is fried. When the machine's rice bowl is replaced with one equipped with a sieve for removing foreign matter, the foreign matter is thrown into the rice bowl of the grain frying machine while circulating inside the machine, where it is passed through a sieve and removed. It can be easily taken out of the machine.

(f) Examples The present invention will be explained below with reference to the drawings of examples.

The rice hulling machine shown in this example is integrated on the machine stand 1, with a removal section A in the front part above the wind sorting part B and a pothole type sorting part C in the rear part, as shown in Fig. 3. The grain lifting machine D is installed upright on the side of this integrally constructed machine body. roll 3
, and is air-selected in a sorting air passage 4 . Through this wind sorting, the rice husks are discharged from the suction dust extractor 5 to the outside of the machine, the rice cakes are taken out from the rice paddy trough 6, and the mixed rice of brown rice and paddy is taken out from the mixed rice extending into the front transverse feed case a. The rice is lifted up from the gutter 7 into the front chamber of the grain frying machine D and thrown into the milled rice spout 8, and from the milled rice spout 8 it is fed into the supply gutter 9.
A transfer gutter 14 passes through the sorting cylinder 13, which has a number of pot holes 12 formed on its inner circumferential surface, and rotates while being supported by a pair of wheels 10 and 11 at the front and rear. It is sent to the side and falls from the drop port 15 onto the inner peripheral surface of the sorting cylinder 13. The mixed rice that has fallen onto this inner circumferential surface is scooped up by the pot hole 12 of the rotating sorting cylinder 13, and the brown rice falls into the receiving gutter 16 and is sent to the front side, and then passes through the brown rice gutter 17 to the The waste rice is led out toward the rear of the wind sorting section B, is removed in the wind selection path 18, and is lifted into the rear chamber of the grain lifting machine D from the brown rice take-out gutter 19 extending into the rear cross-feeding case b. It is taken out to a suitable location outside the machine.

In addition, the paddy left behind from the brown rice is collected in several buckets 2 evenly distributed on the inner circumferential surface of the front end of the sorting barrel 13.
The paddy is lifted up by the paddy roller 0 and falls upward, and this falling paddy is caught by the return gutter 21, returned to the paddy tank 2, and then supplied to the deroller 3 again.
Reference numeral 22 denotes a waste rice removal gutter installed horizontally in the rice route portion of the wind selection path 18, and extends into the front side transverse feed case a at a different level from the mixed rice removal gutter 7.

In addition, due to the scooping action of the pot hole 12, the receiving gutter 1
Rice that cannot be scooped up to 6 drops into the transfer gutter 14, joins with new mixed rice, and is again supplied to the inner peripheral surface of the sorting cylinder 13 from the drop port 15, where it is circulated.

In addition, when the grain lifting machine D is installed on the side of the machine, its lower part is held between the front and rear cross-feeding cases a and b, which respectively protrude outward from the wind sorting section B. Hold it in place and attach the top with a stopper (not shown)
This allows it to be freely attached to the machine wall of the pothole type sorting section C.

Next, the rice milling spout 8 of the grain frying machine D will be described.
All of the milled rice inlets 8 shown in the figures are equipped with a sieve S for removing foreign matter, and communicate between the upper part of the front chamber of the grain frying machine D and the supply gutter 9. The above-mentioned sieve S has a vertical sieve line 23 in which several filaments are laid vertically in a plane to form a vertical sieve surface, and a vertical sieve line 23 in which several filaments are arranged diagonally in a plane similar to the vertical sieve line 23. The vertical sieve line 23 has its sieve surface facing the mixed rice which is fed by bucket from the upper part of the front chamber of the main body of the grain frying machine D. The horizontal sieve line 24 is vertically installed in the rice bowl 8 by a set bolt 25 so that the sieving surface thereof is connected to the mixed rice input path from the front chamber of the main body of the grain lifting machine D to the vertical sieve line 23. 26 and is obliquely installed with a set bolt 27 so that the front side is lower. This horizontal sieve line 24
The portion of the rice-grilling spout 8 constituting the lower portion of the feed gutter 9 is bent slightly toward the back to form a communication path 28.
The back side portion of the vertical sieve wire 23 is bulged forward to form a bulge 29, and the lower part of the bulge 29 directly communicates with the communication path 28.

Further, a foreign matter removal cylinder 31 is attached to the front side wall of the rice-scrubbing spout 8, which has a large opening 30 in the upper part from the horizontal sieve line 24, and which directs this opening 30 downward. A shutter plate 33 with a lever 32 is mounted inside.

34 is a transparent body that constitutes a part of the foreign matter removal tube 31, and 35 is a fastening device that allows the upper part of the milled rice spout 8 to be detachably connected to the upper part of the main body of the grain lifting machine D.

Therefore, if the top of the interior of the front side of the main body of the grain frying machine D is communicated with the supply gutter 9 through the rice milling spout 8 equipped with the sieve S for removing foreign matter, configured as described above, it is possible to prevent foreign matter from getting mixed into the mixed rice. Foreign objects such as pebbles and metal pieces are removed by grain lifting machine D.
The rice is lifted up by a bucket and thrown into the rice-grilling port 8 together with the mixed rice, but as a result of this feeding, the foreign matter hits the vertical sieve line 23 and passes through the vertical sieve line 23 to form a bulge. It falls onto the horizontal sieve wire 24 without reaching the screen 29, flows down the sieve surface of the horizontal sieve wire 24 toward the front side, passes through the opening 30, and is received by the shutter plate 33. The mixed rice of brown rice and paddy passes through the vertical sieve line 23 and is thrown out into the bulging part 29 during the above-mentioned feeding, and the mixed rice that hits the vertical sieve line 23 during the above-mentioned feeding from the bucket is thrown horizontally. It falls onto the sieve surface of the sieve wire 24, but passes through the horizontal sieve wire 24 downward, and is supplied to the pothole type sorting section C from the communication path 28 through the supply gutter 9 along with the mixed rice thrown out into the bulge 29. Become so.

The foreign objects caught on the shutter plate 33 can be removed as appropriate by turning the lever 32, and this is possible even during operation.

In addition, the sieve S is composed of vertical sieve lines 23 and horizontal sieve lines 24, and the vertical sieve lines 23 mainly sieve and work together with the horizontal sieve lines 24 to sort into two stages, so the sieve sorting effect is achieved. This effectively prevents the horizontal sieve wire 24 from clogging.

When replacing the rolled rice spout 8, use the upper retaining tool 35.
Replacement is easy because the lower part can be removed from the supply gutter 9 and replaced with another rice bowl.

(g) Effects of the invention As explained above, this invention has a receiving gutter in the removal part, the wind sorting part, and the sorting cylinder which is rotatably suspended horizontally by forming a number of pot holes on the inner circumferential surface. This is a rice hulling machine that includes a pothole-type sorting section that is inserted horizontally. The polished rice is discharged from the rice bowl and fed to the pot-hole type sorting section, and the rice bowl is configured to be replaceable with one equipped with a sieve for removing foreign matter mixed into the mixed rice. Conventionally, each part of a hulling machine consisting of a dehulling section, a wind sorting section, and a pot-hole type sorting section is constructed in a nearly hermetic manner, so that no foreign matter gets mixed into the mixed rice. Even if it was detected by the generation of abnormal noises, it was difficult to remove the parts, and the parts were circulated many times, causing damage and deformation of each part, reducing its function. However, according to the present invention, if an abnormal noise is detected from inside the machine, the rice dropper can be immediately replaced with one equipped with a sieve for removing foreign matter. It can be easily taken out while driving, and taking it out is a hassle-free operation, making it possible to prevent damage or deformation of various parts.
