Description

本発明は精米機に関するもので、特に、精米開始前または精米終了後に精米機内に残留した米粒等を除去する構造に関する。   The present invention relates to a rice mill, and more particularly, to a structure for removing rice grains and the like remaining in the rice mill before or after the completion of rice milling.

従来、原料の品種換えの際、あるいは精米終了後に、精米機内に残留した米粒等を除去するための残留米清掃装置が知られている。例えば、特許文献1に開示された精米機について図7を用いて説明すると、横向きの除糠用多孔壁精白筒105内に精白転子111を軸架して、精白筒105と精白転子111との間隙に精白室103を形成し、該精白室103の一方側に抵抗蓋107を備えた米粒排出口108を設けるとともに、精白筒105の他方側に送穀室118を介して連通する米粒供給口109を設けた精米機において、前記送穀室118側壁には、前記精白室103及び送穀室118の底面に残留する米粒を吹掃する清掃用噴風孔116を設けるとともに、該噴風孔116に送管120を介して空気圧縮装置117に連絡したものであり、これにより、精米終了後に、精白室103及び送穀室118に残留する米粒が、噴風孔116からの噴風作用によって吹掃されて、抵抗蓋107が開口されたときに米粒排出口108から排出され、精白室103及び送穀室117が清掃されるのである。   2. Description of the Related Art Conventionally, there is known a residual rice cleaning device for removing rice grains and the like remaining in a rice milling machine when changing the varieties of raw materials or after finishing the rice milling. For example, a rice milling machine disclosed in Patent Document 1 will be described with reference to FIG. 7. A milling trochanter 111 is pivoted in a laterally facing porous wall milling cylinder 105, and the milling cylinder 105 and the milling trochanter 111 are arranged. And a rice grain outlet 108 provided with a resistance lid 107 on one side of the milling chamber 103 and a rice grain communicating with the other side of the milling cylinder 105 via a cerealing chamber 118. In the rice milling machine provided with the supply port 109, cleaning blast holes 116 for sweeping rice grains remaining on the bottom surfaces of the milling chamber 103 and the cerealing chamber 118 are provided on the side wall of the cerealing chamber 118, and The air holes 116 communicated with the air compression device 117 via the feeding pipe 120, so that the rice grains remaining in the milling chamber 103 and the threshing chamber 118 after the completion of the milling are blown from the blowing holes 116. When the resistance lid 107 is opened by the action, it is discharged from the rice grain outlet 108, and the milling chamber 103 and the cerealing chamber 117 are cleaned. Than it is.

しかしながら、上記従来技術にあっては、清掃用噴風孔116が送穀室118側壁に設けられ、該清掃用噴風孔116からの噴風のみで送穀室118及び精白室103を吹掃することになるから、精白室103先端部にある米粒排出口108まで米粒を移送するためには、米粒が滞留しないよう空気圧縮装置117により圧縮された高圧空気により噴風したり、風量の大きなファン等で噴風したりする必要があり、風量の小さなファン等では代用することができないといった問題があった。   However, in the above prior art, the cleaning blast hole 116 is provided on the side wall of the cerealing chamber 118, and the cerealing chamber 118 and the whitening chamber 103 are blown out only by the blast from the cleaning blast hole 116. Therefore, in order to transfer the rice grains to the rice grain outlet 108 at the tip of the whitening chamber 103, the rice grains are blown by high-pressure air compressed by the air compressor 117 so that the rice grains do not stay, or the air volume is large. There is a problem that it is necessary to blow with a fan or the like, and a fan with a small air volume cannot be substituted.

また、送穀室118と精白室103との継ぎ目Aや、送穀室118や精白室103の形状によっては、噴風の流れが悪くなる箇所が生じ、この部分に米溜りが生じるおそれもあった。   In addition, depending on the joint A between the cerealing chamber 118 and the milling chamber 103 and the shape of the cerealing chamber 118 and the milling chamber 103, there may be a part where the flow of the blast is worsened, and there is a possibility that rice pools may occur in this part. It was.

本発明は上記問題点にかんがみ、空気圧縮装置や、風量の大きなファン等を用いることなく、風量の小さな小型ファンにより生成した噴風であっても確実に残留米を排出することができる精米機を提供することを技術的課題とする。   In view of the above problems, the present invention provides a rice mill that can reliably discharge residual rice even with a blast generated by a small fan with a small air volume, without using an air compressor or a fan with a large air volume. It is a technical challenge to provide

上記課題を解決するため本発明は、玄米ホッパー(16)と、該玄米ホッパー(16)と連通する玄米供給路(17)と、該玄米供給路(17)の流路を開閉する穀粒供給シャッター(10)と、前記玄米供給路(17)と連通する送穀室(18)と、該送穀室(18)内に回転可能に軸装した送穀ロール(19)と、前記送穀室(18)と連通した精白室(20)と、該精白室(20)内に回転可能に軸装した精白ロール(21)とを備えた精米機において、前記送穀室(18)は、横軸(29)と同軸上の円筒(23)によって構成するとともに、該円筒(23)の下半部分を、前記送穀ロール(19)のネジ山部(19a)から円筒(23)内周面までの間隙(d1)が狭い小ハウジング部(24)と、ネジ山部(19a)から円筒(23)内周面までの間隙(d2)が広い大ハウジング部(25)と、前記小ハウジング部(24)と前記大ハウジング部(25)とを接合する傾斜面(26)とにより構成する一方、前記玄米供給路(17)の側壁には、前記円筒(23)の下半部分へ向けて吹掃する清掃用噴風孔(43)を穿設するとともに、該噴風孔(43)には、噴風管(45)を介して小風量の噴風を送給する小型ファン(44)を接続する、という技術的手段を講じた。 In order to solve the above problems, the present invention provides a brown rice hopper (16), a brown rice supply path (17) communicating with the brown rice hopper (16), and a grain supply for opening and closing the flow path of the brown rice supply path (17). A shutter (10), a cerealing chamber (18) communicating with the brown rice supply channel (17), a cerealing roll (19) rotatably mounted in the cerealing chamber (18), and the cerealing In a rice mill comprising a milling chamber (20) communicating with a chamber (18), and a milling roll (21) rotatably mounted in the milling chamber (20), the cerealing chamber (18), The cylinder (23) is coaxial with the horizontal axis (29), and the lower half of the cylinder (23) is connected to the inner periphery of the cylinder (23) from the thread portion (19a) of the cerealing roll (19). A small housing part (24) with a small gap (d1) to the surface, a large housing part (25) with a wide gap (d2) from the threaded part (19a) to the inner peripheral surface of the cylinder (23), and the small housing Part (24) and the inclined surface (26) joining the large housing part (25) On the other hand, on the side wall of the brown rice supply path (17), a cleaning blowing hole (43) for blowing toward the lower half of the cylinder (23) is formed, and the blowing hole (43 ) Was equipped with a technical means of connecting a small fan (44) for supplying a small amount of blast through the blast tube (45).

送穀室(18)を形成する円筒(23)の下半部分において、前記送穀ロール(19)のネジ山部(19a)から円筒(23)内周面までの間隙(d1)が狭い小ハウジング部(24)と、ネジ山部(19a)から円筒(23)内周面までの間隙(d2)が広い大ハウジング部(25)と、前記小ハウジング部(24)と前記大ハウジング部(25)とを接合する傾斜面(26)とにより構成しているから、小ハウジング部(24)においてはネジ山部(19a)から円筒(23)内周面までの間隙(d1)が狭いために円筒(23)の体積が小さくなり、送穀ロール(19)による送穀作用と噴風口(43)からの噴風作用とによって、比較的弱い噴風であっても小ハウジング部(24)内の隅々に噴風が行き渡り、残留米が滞留しにくく、確実に清掃することができる。そして、小ハウジング部(24)から排出された残留米は、傾斜面(26)および大ハウジング部(25)を転動して精白室(20)に移送されるため、送穀室(18)と精白室(20)との継ぎ目に米溜りが生じるおそれはない。また、精白室(20)においても同様に、精白ロール(21)の回転による送穀作用と噴風口(43)からの噴風作用とによって残留米を排出口(28)から排出して完全に清掃される。これにより、高価な空気圧縮装置や大風量の大型ファンを用いることなく、安価な小型ファンにより残留米除去装置を提供することが可能になった。 In the lower half of the cylinder (23) forming the cerealing chamber (18), the gap (d1) from the threaded portion (19a) of the cerealing roll (19) to the inner peripheral surface of the cylinder (23) is small. A housing part (24), a large housing part (25) having a wide gap (d2) from the thread part (19a) to the inner peripheral surface of the cylinder (23), the small housing part (24) and the large housing part ( 25) and the inclined surface (26) that joins, the small housing part (24) has a narrow gap (d1) from the threaded part (19a) to the cylindrical (23) inner peripheral surface. The volume of the cylinder (23) is reduced, and the small housing part (24) even with a relatively weak blast due to the cerealing action by the cerealing roll (19) and the blasting action from the blast outlet (43) Fountains spread all over the corner, and the remaining rice is less likely to stay and can be cleaned reliably. The residual rice discharged from the small housing portion (24) rolls on the inclined surface (26) and the large housing portion (25) and is transferred to the milling chamber (20). There is no risk of rice pooling at the seam between the milling chamber and the milling chamber (20). Similarly, in the milling chamber (20), residual rice is completely discharged from the discharge port (28) by the cerealing action by the rotation of the milling roll (21) and the blast action from the blast port (43). To be cleaned. This makes it possible to provide a residual rice removing device using an inexpensive small fan without using an expensive air compressor or a large fan with a large air volume.

以下、上記構成における作用を説明する。精米機利用者が原料となる玄米を穀粒投入ホッパー2内に投入するとともに、あらかじめ玄米戻し樋15側に二方向切換弁13を切換え、調圧ダイヤル9を「0」にセットしておく。次いで、精米に必要な所定金額を図示しないコインタイマーに投入すると、操作パネル11が操作可能となり、この状態で運転スイッチをオンすると精米機1の各駆動部が所定時間駆動することになる。これにより、穀粒投入ホッパー2内の玄米は揚穀コンベア6により揚穀され、穀粒タンク8を介して下方の精米機本体4に供給される。精米機本体4では、穀粒供給シャッター10のノブ10aを引いてシャッター10を開き、前記調圧ダイヤル9を所望の位置にセットし直す。玄米は、供給路17であらかじめ調整した流量調整シャッター22よって一定流量で安定的に送穀室18へ供給されることになる。 Hereinafter, the operation of the above configuration will be described. A rice milling machine user introduces brown rice as a raw material into the grain input hopper 2 and switches the two-way switching valve 13 to the brown rice return grinder 15 side in advance and sets the pressure adjustment dial 9 to “0”. Next, when a predetermined amount required for rice milling is put into a coin timer (not shown), the operation panel 11 can be operated. When the operation switch is turned on in this state, each drive unit of the rice milling machine 1 is driven for a predetermined time. Thereby, the brown rice in the grain input hopper 2 is cerealed by the cereal conveyor 6 and supplied to the lower rice mill body 4 via the grain tank 8. In the rice milling machine body 4, the knob 10a of the grain supply shutter 10 is pulled to open the shutter 10, and the pressure adjusting dial 9 is reset to a desired position. The brown rice is stably supplied to the cerealing room 18 at a constant flow rate by the flow rate adjusting shutter 22 adjusted in advance in the supply path 17.

送穀室18へ供給された玄米は、送穀ロール19の回転作用によって精白室20に送り込まれ、この精白室20の排出口28を押圧する抵抗蓋37、及び精白室20内で回転する精白ロール21によって玄米を攪拌しながら搗精圧力をかけて糠層を除去し、精米が行われる。この際、除去される糠は、除糠室40から集糠管41を介して除糠サイクロン7に集糠された後、除糠サイクロン7下方の紙袋Nに回収されることになる。 The brown rice supplied to the cerealing chamber 18 is fed into the milling chamber 20 by the rotating action of the cerealing roll 19, and the resistance lid 37 that presses the discharge port 28 of the milling chamber 20, and the whitening that rotates in the milling chamber 20. While the brown rice is stirred by the roll 21, the milling layer is removed by applying milling pressure to perform milling. At this time, the removed soot is collected in the removal cyclone 7 from the removal chamber 40 via the collection tube 41 and then collected in the paper bag N below the removal cyclone 7.

玄米から糠層が除去された米粒は、排出口28および精品排出樋12を介して機外に取り出されることになる。このとき、搗精初期は精白室20内の圧力が低いためムラ搗きになりやすく、二方向切換弁13、玄米戻し樋15、穀粒投入ホッパー2、揚穀コンベア6、穀粒タンク8を介して精米機本体4に返還され、再搗精されることになる。そして、利用者が目視により所望の白度に達したと判断すれば、二方向切換弁13を石抜き機投入樋14側に切換えて石抜き作業が開始される。 The rice grains from which the rice bran layer has been removed from the brown rice are taken out of the machine through the discharge port 28 and the refined product discharge basket 12. At this time, since the pressure in the whitening chamber 20 is low at the initial stage of milling, it is likely to be uneven, and the two-way switching valve 13, the brown rice return grind 15, the grain loading hopper 2, the cereal conveyor 6, and the grain tank 8 are used. It will be returned to the rice milling machine body 4 and will be refined again. Then, if the user visually determines that the desired whiteness has been reached, the two-way switching valve 13 is switched to the side of the stone removing machine loading rod 14 and the stone removal operation is started.

精米機本体4から排出された白米及び当該白米に混入する石屑は、石抜き機5の選別ケース5b上に供給され、白米は精品排出樋5dから排出されて紙袋Sに袋詰めされるとともに、石屑は揺り上げ側に寄せられて石抜き樋5cから排出されることになる。また、選別ケース5b上に溜まった残留米は石・残留米回収箱5eに、選別ケース5bの多孔選別板を通過した砕米は砕米回収箱5fにそれぞれ回収されることになる。 The white rice discharged from the rice mill main body 4 and the stone chips mixed in the white rice are supplied onto the sorting case 5b of the stone removing machine 5, and the white rice is discharged from the fine product discharge basket 5d and packed in a paper bag S. The debris is brought to the rocking side and discharged from the stone punching cage 5c. Further, the residual rice collected on the sorting case 5b is collected in the stone / residual rice collection box 5e, and the broken rice that has passed through the porous sorting plate of the sorting case 5b is collected in the broken rice collection box 5f.

以上のように精米処理が行われるのであるが、精米終了時に一部の米粒が送穀室18および精白室20に残留することになる。そこで、本発明の精米機1では、精米終了後、前記穀粒供給シャッター10を閉鎖し、送穀ロール19および精白ロール21を回転させながら小型ファン44を作動することにより送穀室18および精白室20に残留した残留米を確実に清掃することができる。   Although the rice milling process is performed as described above, some rice grains remain in the cerealing chamber 18 and the milling chamber 20 at the end of the milling. Therefore, in the rice milling machine 1 of the present invention, after the milling is finished, the grain supply shutter 10 is closed, and the small fan 44 is operated while rotating the cerealing roll 19 and the milling roll 21, so that the cerealing chamber 18 and milling are performed. Residual rice remaining in the chamber 20 can be reliably cleaned.

すなわち、本発明の精米機1は、送穀室18を形成する円筒23の下半部分において、図4に示すように、送穀ロール19のネジ山部19aから円筒23内周面までの間隙d1が狭い(約0.5mm)小ハウジング部24と、ネジ山部19aから円筒23内周面までの間隙d2が広い(約4mm)大ハウジング部25と、前記小ハウジング部24と前記大ハウジング部25とを接合する傾斜面26とによって構成されているから、小ハウジング部24においてはネジ山部19aから円筒23内周面までの間隙d1が狭いために、円筒(23)の体積が小さくなり、送穀ロール19による送穀作用と噴風口43からの噴風作用とによって、比較的弱い噴風であっても小ハウジング部24内の隅々に噴風が行き渡り、残留米が滞留しにくく、確実に清掃することができる。そして、小ハウジング部24から排出された残留米は、傾斜面26および大ハウジング部25を転動して精白室20に移送されるため、送穀室18と精白室20との継ぎ目に米溜りが生じるおそれはない。また、精白室20においても同様に、精白ロール21の回転による送穀作用と噴風口43からの噴風作用とによって残留米を排出口28から排出して完全に清掃される。これにより、高価な空気圧縮装置や大風量の大型ファンを用いることなく、安価な小型ファンにより残留米除去装置を提供することが可能になった。 That is, in the lower half portion of the cylinder 23 that forms the cerealing chamber 18, the rice mill 1 of the present invention has a gap from the thread 19a of the cerealing roll 19 to the inner peripheral surface of the cylinder 23 as shown in FIG. a small housing portion 24 with a small d1 (about 0.5 mm), a large housing portion 25 with a wide gap d2 from the threaded portion 19a to the inner peripheral surface of the cylinder 23 (about 4 mm), the small housing portion 24 and the large housing Since the gap d1 from the screw thread portion 19a to the inner peripheral surface of the cylinder 23 is narrow in the small housing portion 24, the volume of the cylinder (23) is small. Thus, due to the cerealing action by the cerealing roll 19 and the blasting action from the blast outlet 43, even if it is a relatively weak blast, the blast spreads to every corner in the small housing portion 24, and the residual rice stays. Hard and reliable cleaning can do. And since the residual rice discharged | emitted from the small housing part 24 rolls the inclined surface 26 and the large housing part 25, and is transferred to the whitening chamber 20, a rice pool is carried out to the joint of the cerealing room 18 and the whitening room 20. There is no risk of occurrence. Similarly, in the milling chamber 20, residual rice is discharged from the outlet 28 by the cerealing action by the rotation of the milling roll 21 and the blast action from the blast outlet 43 and is completely cleaned. This makes it possible to provide a residual rice removing device using an inexpensive small fan without using an expensive air compressor or a large fan with a large air volume.

なお、前記送穀室18を形成する円筒23の送穀ロール19下方部分は、小ハウジング部24、大ハウジング部25及び傾斜面26からなる鋳物で形成することが好ましいが、これに限定されることはなく、図5に示すように、図6に示すスペーサー23bを円筒23内に嵌合することで、小ハウジング部24、大ハウジング部25及び傾斜面26を形成することもできる。 In addition, although it is preferable to form the cerealing roll 19 lower part of the cylinder 23 which forms the said cerealing chamber 18 with the casting which consists of the small housing part 24, the large housing part 25, and the inclined surface 26, it is limited to this. However, as shown in FIG. 5, the small housing part 24, the large housing part 25, and the inclined surface 26 can be formed by fitting the spacer 23b shown in FIG.
