Can be recovered. Even if a dust collector is provided in a narrow space where the rear part of a grain dryer or the like approaches the warehouse wall, the dust collecting cylinder rotates upward, so that no extra space is required and it can be arranged compactly.

請求項１に記載の発明は、ノズル環の噴口から出る水によって捕捉された塵埃類は下方の遠心分離機内に入り、回転する回転容器の集塵バッグに受けられ、捕捉した塵埃は集塵バッグ内に残る一方集塵バッグの目合を通過した水は受け皿で受けられた後排水部を経て水槽に至るから、水槽に溜まった塵埃類は放置されず集塵バッグにて所定に排出されることとなりその取り扱いが簡単であり、なお排水部を経て水槽に至った水は還元利用できる。また、ノズル環の円周方向に噴口を設ける形態であるから、排気風に対する水噴出の偏りを防いで的確に浮遊する塵埃類を捕捉できる。 According to the first aspect of the present invention, dust trapped by the water coming out from the nozzle ring nozzle enters the lower centrifugal separator and is received by the dust collecting bag of the rotating rotating container, and the trapped dust is collected by the dust collecting bag. On the other hand, the water that has passed through the mesh of the dust collection bag is received by the tray and then reaches the water tank through the drainage section.

The dust bag can be collected. Even if a dust collector is provided in a narrow space where the rear part of a grain dryer or the like approaches the warehouse wall, the dust collecting cylinder rotates upward, so that no extra space is required and it can be arranged compactly.

前記遠赤外線放射体１０の入口側には、乾燥機正面に配置するバーナ１３からの熱風を受け入れる構成である。即ち、バーナ１３は気化型バーナとされ、正面向きの燃焼盤１３ａの中央部に横軸周りの回転気化筒１３ｂを備え、気化筒１３ｂの内側に設ける燃料ノズル（図示せず）からの噴出燃料は燃焼火炎を受けて加熱する気化筒１３ｂによって気化され燃焼盤１３ａから噴出しながら燃焼を継続する構成である。 The far-infrared radiator 10 is configured to receive hot air from a burner 13 disposed in front of the dryer on the inlet side. That is, the burner 13 is a vaporization-type burner, and includes a rotary vaporization cylinder 13b around the horizontal axis at the center of the front-facing combustion disc 13a, and fuel ejected from a fuel nozzle (not shown) provided inside the vaporization cylinder 13b. Is configured to continue combustion while being vaporized by a vaporizing cylinder 13b that receives and heats a combustion flame and is ejected from the combustion disk 13a.

気化型バーナ１３は次のように装着される。基板２３に対して断面矩形の支持筒１３ｃをもって送風筒１３ｄが支持されている。この基板２３には該支持筒１３ｃの左右に位置してイグナイタ１３ｅ用トランス１３ｆ及び上記燃料ノズルを接続する燃料ポンプ１３ｇを装着し、該支持筒１３ｃ前側には外気導入口１３ｈ及び前面を導入口１３ｈに形成した案内ガイド１３ｉを設けている。１３ｊは配線部、１３ｋは燃料供給管である。 The vaporizing burner 13 is mounted as follows. The blower cylinder 13d is supported by the substrate 23 with a support cylinder 13c having a rectangular cross section. An igniter 13e transformer 13f and a fuel pump 13g for connecting the fuel nozzle are mounted on the substrate 23 on the left and right of the support cylinder 13c, and an outside air inlet 13h and a front surface are provided on the front side of the support cylinder 13c. A guide 13i formed at 13h is provided. 13j is a wiring part and 13k is a fuel supply pipe.

図４におけるように、風胴上面にはコントローラ４０を着脱ボルト等によって装着している。また、このコントローラ４０は上面及び左右面、さらには後ろの空間部を覆うようにコントローラカバーを着脱可能に設けられる。また、風胴１４正面側には適宜に通風孔３６ａを形成した正面カバー３６を着脱自在に設けている。なお、この正面カバー３６はコントローラ４０の操作盤４１面を除いた枠型に形成されていて一枚のカバー板部材にて賄われている。 As shown in FIG. 4, a controller 40 is mounted on the upper surface of the wind tunnel with a detachable bolt or the like. The controller 40 is detachably provided with a controller cover so as to cover the upper surface, the left and right surfaces, and the rear space. In addition, a front cover 36 in which ventilation holes 36a are appropriately formed is detachably provided on the front side of the wind tunnel 14. The front cover 36 is formed in a frame shape excluding the operation panel 41 surface of the controller 40 and is covered by a single cover plate member.

上記バーナ風胴１４内のバーナ１３は遠赤外線放射体１０の入口部と連通している。即ち、機体前側壁３ａの外側に位置する断面四角形状の上記バーナ風胴１４を装着し、該前側壁３ａの内側には遠赤外線放射体１０の一端を装着する一方、案内ダクト２８を装着する。該案内ダクト２８は、前側壁３ａに形成する導入口３ｂに略同形の断面略四角形状の短筒体に形成され、遠赤外線放射体１０の始端側部分に外装状態で装着されるものである。従って、バーナによる燃焼熱気が主として遠赤外線放射体１０断面に入り込むのに対し、バーナ風胴１４に導入される外気は、遠赤外線放射体１０の外周部を案内ダクト２８内周に沿って吹き抜ける構成である。 The burner 13 in the burner wind tunnel 14 communicates with the entrance of the far-infrared radiator 10. In other words, the burner wind tunnel 14 having a quadrangular cross section located outside the airframe front side wall 3a is mounted, and one end of the far-infrared radiator 10 is mounted inside the front side wall 3a, while the guide duct 28 is mounted. . The guide duct 28 is formed in a short cylindrical body having a substantially rectangular cross section in the introduction port 3b formed in the front side wall 3a, and is attached to the starting end side portion of the far-infrared radiator 10 in an exterior state. . Therefore, the combustion air generated by the burner mainly enters the cross section of the far infrared radiator 10, whereas the outside air introduced into the burner wind tunnel 14 blows through the outer peripheral portion of the far infrared radiator 10 along the inner periphery of the guide duct 28. It is.

上記バーナ風胴１４に導入される外気は、バーナ１３に気化型バーナを構成する場合の二次空気供給の役割を果たしながら上記のように熱風室６に入って熱風温度の上昇を抑制する機能を備えるものである。 The outside air introduced into the burner wind tunnel 14 functions as a secondary air supply when the burner 13 constitutes a vaporization type burner and enters the hot air chamber 6 as described above to suppress the rise of the hot air temperature. Is provided.

ところで、バーナ燃焼熱気は遠赤外線放射体１０に入るとそのまま後方に案内されて却って入口側上部付近の温度が低い傾向にあり、これを是正するため、上記のようにスリット状開口１１を形成するものであり、従って、この部分への外気導入は更に温度を低下させるため、この外気導入を遮断すべく遮蔽板２９，２９を、案内ダクト２８の後部側において遠赤外線放射体１０の外周部に作用できないように設けている。 By the way, when the burner combustion hot air enters the far-infrared radiator 10 and is guided rearward as it is, the temperature near the upper part on the inlet side tends to be low. In order to correct this, the slit-shaped opening 11 is formed as described above. Therefore, since the introduction of the outside air into this portion further reduces the temperature, the shielding plates 29 and 29 are disposed on the outer peripheral portion of the far-infrared radiator 10 on the rear side of the guide duct 28 to block the introduction of the outside air. It is provided so that it cannot act.

このように構成すると、遠赤外線放射体１０の前側部の開口１１による温度上昇、及び案内ダクト２８による外気導入の抑制とが相俟って、バーナ１３に近い熱風室６入口上部の温度上昇を促進し、熱風室６全体の温度分布が適正範囲となるよう均等化することができる。 If comprised in this way, the temperature rise by the opening 11 of the front side part of the far-infrared radiator 10 and the suppression of outside air introduction by the guide duct 28 combine, and the temperature rise of the hot air chamber 6 upper part near the burner 13 is increased. It is possible to promote and equalize so that the temperature distribution of the entire hot air chamber 6 falls within an appropriate range.

また、前記のように、バーナ風胴１４の前面には乾燥機用コントローラ（制御部）４０を設けている（図５）。バーナ風胴１４の正面にはコントローラ４０操作盤４１を備えている。この操作盤４１には張込スイッチ４２、通風スイッチ４３、乾燥スイッチ４４、排出スイッチ４５、停止スイッチ４６を備え、これらのスイッチ群により各種の運転モードに切り替えると共に運転停止を司る。また、緊急スイッチ４７を設け、この緊急スイッチ４７を操作すると、機体運転部の全体を略同時に停止することができる。 As described above, the dryer controller (control unit) 40 is provided in front of the burner wind tunnel 14 (FIG. 5). A controller 40 operation panel 41 is provided in front of the burner wind tunnel 14. The operation panel 41 includes a tension switch 42, a ventilation switch 43, a drying switch 44, a discharge switch 45, and a stop switch 46.

これらのスイッチ４２〜４７の他に、張込量を設定する張込量設定スイッチ４８、最終仕上げ水分値を設定する水分設定スイッチ４９、及び、乾燥設定スイッチ５０（籾乾燥の場合には乾燥速度を速い・普通・遅いに設定し、また、他の穀粒乾燥の場合には、例えば小麦・大麦等の品種に関連付けて予め設定した乾燥速度に設定する）を備えている。更に、乾燥仕上がりを水分値によらないで処理時間により乾燥する等のためのタイマ増・減スイッチ５１，５２を備えている。 In addition to these switches 42 to 47, a tension amount setting switch 48 for setting the tension amount, a moisture setting switch 49 for setting the final finishing moisture value, and a drying setting switch 50 (drying speed in the case of drought drying) Is set to fast, normal, and slow, and in the case of other grain drying, for example, a drying speed set in advance in association with varieties such as wheat and barley is set. Furthermore, timer increase / decrease switches 51 and 52 are provided for drying the finished product according to the processing time without depending on the moisture value.

水分検出手段は一粒式の水分計５３を採用し、所定時間毎に所定粒数単位で水分値を測定し、所定回数の検出結果を平均処理して水分値を算出し、前記操作盤４１の表示部５４に検出熱風温度等と交代的に表示する構成である。制御部４０は併せて一粒水分値から水分のバラツキを判定したり、未熟粒の多少を判定できる構成とし、これらを３個のＬＥＤ５５，５６により表示している。 The moisture detection means employs a single-grain moisture meter 53, measures the moisture value in units of a predetermined number of grains every predetermined time, averages the detection results for a predetermined number of times, calculates the moisture value, and operates the operation panel 41. The display unit 54 alternately displays the detected hot air temperature and the like. In addition, the control unit 40 is configured to be able to determine the variation in moisture from the moisture value of one grain or to determine the number of immature grains, and these are displayed by three LEDs 55 and 56.

制御部４０には、操作盤４１のスイッチから運転モード情報等を入力するほか、各種センサから検出情報が入力され、前記気化型バーナ１３の燃料供給量を制御したり、穀粒の移送系手段を運転制御するように構成している。 In addition to inputting operation mode information and the like from the switch of the operation panel 41 to the control unit 40, detection information is input from various sensors to control the fuel supply amount of the vaporizing burner 13 and to transfer the grain.

Yes. These nozzle rings 61a, 61b, 61c are connected to introduction pipes 63a, 63b, 63c, respectively, and these introduction pipes 63a, 63b, 63c are branched from the collection pipe 64 outside the dust collection cylinder 59. (FIG. 9), It is the structure which can introduce high pressure water from the pump means mentioned later. The collecting pipe 64 and each introduction pipe 63 are detachably configured by a joining means 64a.

上記胴部５９ｃの中央下部に連通口５９ｄを開口し、断面四角の筒体５９ｅを固着している。この筒体５９ｅを遠心分離器６０の蓋体６５の中央開口部に連設した相似形状の受筒体６５ａに上部側から着脱自在に嵌合しうる構成としている。 A communication port 59d is opened at the center lower portion of the body portion 59c, and a cylindrical body 59e having a square cross section is fixed. This cylindrical body 59e is configured to be detachably fitted from the upper side to a similar receiving cylindrical body 65a provided continuously to the central opening of the lid body 65 of the centrifuge 60.

上記遠心分離器６０は、上記蓋体６５で施蓋される本体６６内に、側壁部に多数の通孔６７ａが形成され上部側をやや径大に形成した円筒形状の容器６７を縦軸６８周りに回転自在に支架させて設けると共に、該回転容器６７の下方には受け皿６９を設けている。また、回転容器６７の内周面に沿って集塵バッグ７０を係止紐７０ａによって着脱固定自在に設ける構成である。すなわち、集塵バッグ７０は塵埃類を捕捉するフィルタ部材としての機能を有し、所定メッシュの繊維や樹脂等で可撓性を備えた袋状の形態であり、その入り口側外周に係止紐７０ａを備え、集塵バッグ７０を回転容器６７の内部にセットして該係止紐７０ａで固定することができる。 The centrifuge 60 includes a cylindrical container 67 in which a large number of through holes 67a are formed in a side wall portion and a slightly larger diameter is formed on the upper side in a main body 66 covered with the lid body 65. In addition to being rotatably supported around, a tray 69 is provided below the rotating container 67. Further, the dust collection bag 70 is provided along the inner peripheral surface of the rotating container 67 so as to be detachably fixed by the locking string 70a. That is, the dust collection bag 70 has a function as a filter member that captures dust, and is a bag-like form having flexibility with fibers, resin, etc. of a predetermined mesh, and a locking string is provided on the outer periphery of the entrance side. 70a, and the dust collection bag 70 can be set inside the rotary container 67 and fixed with the locking string 70a.

７１は上記縦軸６８の下端に設ける伝動プーリで、本体底部に固定する駆動モータ７２の回転を受けて回転容器６７を一定方向に一定の速度で回転させる構成である。 Reference numeral 71 denotes a transmission pulley provided at the lower end of the vertical axis 68. The transmission pulley 71 rotates the rotary container 67 at a constant speed in a constant direction in response to the rotation of a drive motor 72 fixed to the bottom of the main body.

上記受け皿６９の本体６６側部には開口６６ａが設けられ、回転容器６７から排出される水を受けシュート状の排水部６６ｂを経て本体側部の水槽７３に排水案内される構成である。 An opening 66a is provided on the side of the main body 66 of the tray 69, and the water discharged from the rotating container 67 is received and guided to the water tank 73 on the side of the main body through a chute-shaped drainage portion 66b.

上記水槽７３には内部貯留の水を汲み上げるポンプ手段７４を設け、前記集合パイプ６４に高圧水を供給しうる構成である。また、水槽７３にはフロートスイッチ７５を設け、水槽７３内の水位が所定以下になると該スイッチ７５はオンして水道蛇口に接続するバルブ７７を開作動して水槽７３内に水を補給できる構成としている。 The water tank 73 is provided with a pump means 74 for pumping up the internally stored water so that high-pressure water can be supplied to the collecting pipe 64. Further, the water tank 73 is provided with a float switch 75, and when the water level in the water tank 73 becomes a predetermined level or less, the switch 75 is turned on and the valve 77 connected to the water tap is opened to supply water into the water tank 73. It is said.

７８，７８は前記集塵筒５９の前後を所定高さに支持する搬送自在な脚部材であり、伸縮調整自在に２重筒によって構成され固定ボルト７８ａ，７８ａで任意の高さに設定できる。７９は前記集塵筒５９の排気部５９ｂに接続する可撓性の排気ダクトで、倉庫壁面に設ける任意の排出口に挿通して戸外に排気しうる。 Reference numerals 78 and 78 denote transportable leg members that support the front and rear of the dust collecting cylinder 59 at a predetermined height. The leg members 78 and 78 are double cylinders that can be freely expanded and contracted, and can be set to arbitrary heights with fixing bolts 78a and 78a. Reference numeral 79 denotes a flexible exhaust duct connected to the exhaust part 59b of the dust collecting cylinder 59, which can be inserted into an arbitrary outlet provided on the wall surface of the warehouse and exhausted outdoors.

次に、前記構成の作用について説明する。 Next, the operation of the above configuration will be described.

張込ホッパ（図示省略）に投入された穀粒は、張込スイッチ４２をＯＮすることにより駆動される昇降機１７、上部搬送装置３２等を経由して貯溜タンク２に張り込まれる。穀粒の張込が完了すると、乾燥作業に移行するが、前段階で水分設定スイッチ４９及び乾燥設定スイッチ５０により穀粒種類の設定や希望の乾燥仕上げ水分値を設定する。 The grain thrown into the tension hopper (not shown) is tensioned into the storage tank 2 via the elevator 17, the upper transport device 32, and the like that are driven by turning on the tension switch 42. When the squeezing of the grain is completed, the process proceeds to a drying operation. In the previous stage, the setting of the grain type and the desired dry finish moisture value are set by the moisture setting switch 49 and the drying setting switch 50.

前記の設定操作の終了後に乾燥スイッチ４４をＯＮすると、昇降機１７、上・下搬送装置２５，３１、繰出バルブ７等の駆動が開始されると共に、バーナ１３も駆動されて熱風が乾燥室３の菱形空間である熱風室６の入口部に向けて供給される。 When the drying switch 44 is turned on after the setting operation is completed, the elevator 17, the upper / lower transport devices 25 and 31, the feeding valve 7 and the like are started to be driven, and the burner 13 is also driven so that the hot air flows into the drying chamber 3. It is supplied toward the entrance of the hot air chamber 6 which is a rhombus space.

ここで、バーナの火炎は吸引ファン１５の回転により熱風化され、適宜に導入される外気と混合されながら遠赤外線放射体１０内に流入し、遠赤外線放射体１０を加熱しつつ上部及び下部に形成されているスリット状開口１１、１２を経て遠赤外線放射体１０の外に流出する。その際に遠赤外線放射体１０の加熱により遠赤外線放射体１０の表面から遠赤外線が放射されて、この熱放射及び前記熱風は共に流下通路５，５を流下中の穀粒に作用し、遠赤外線による輻射熱と熱風により穀粒内部での水分移行が促進され、熱風による水分除去作用に伴って効率的な乾燥作用が行なわれる。 Here, the flame of the burner is hot-aired by the rotation of the suction fan 15, flows into the far-infrared radiator 10 while being mixed with the outside air introduced as appropriate, and heats the far-infrared radiator 10 to the upper and lower parts. It flows out of the far-infrared radiator 10 through the formed slit-shaped openings 11 and 12. At that time, far-infrared rays are emitted from the surface of the far-infrared radiator 10 by the heating of the far-infrared radiator 10, and both the thermal radiation and the hot air act on the grains flowing down through the flow-down passages 5 and 5, Moisture transfer inside the grain is promoted by radiant heat and hot air by infrared rays, and an efficient drying action is performed along with the water removing action by the hot air.

なお、バーナ風胴１４に入り込んでバーナ１３の外周を流通する導入外気は、バーナ燃焼用二次空気供給の機能を行った後、前側壁３ａから熱風室６に入るが熱風ダクト２８に沿って遠赤外線放射体１０の外周を流通し、熱風室６入口部の温度上昇を抑制する。なお、遮蔽板２９，２９を設けることによって当該遮蔽板２９，２９部で外気流通は遮断され、温度低下を抑制している。 The introduced outside air that enters the burner wind tunnel 14 and circulates around the outer periphery of the burner 13 enters the hot air chamber 6 from the front side wall 3 a after performing the function of supplying secondary air for burner combustion, but along the hot air duct 28. Circulates the outer periphery of the far-infrared radiator 10 and suppresses the temperature rise at the inlet of the hot air chamber 6. In addition, by providing the shielding plates 29 and 29, the outside air circulation is blocked by the shielding plates 29 and 29, and the temperature drop is suppressed.

穀物流下通路５，５の前後に亘って遠赤外線の放射と熱風による乾燥作用がなされ、穀物流下通路５，５を通過した熱風は排風室１６，１６を経て排風される。乾燥室３で乾燥された穀粒は、集穀室４の下部搬送装置２５、昇降機１７、上部移送螺旋３１を経由して再び貯溜タンク２に戻されて調質作用を受ける。このような行程を繰り返し、所定の水分値に達すると乾燥が終了するものである。 Far-infrared radiation and hot air are dried over the grain flow passages 5 and 5, and the hot air passing through the grain flow passages 5 and 5 is exhausted through the exhaust chambers 16 and 16. The grain dried in the drying chamber 3 is returned again to the storage tank 2 via the lower conveying device 25, the elevator 17 and the upper transfer spiral 31 of the cereal collecting chamber 4, and undergoes a tempering action. Such a process is repeated and drying is completed when a predetermined moisture value is reached.

上記乾燥作業中、乾燥機の後部側に集塵装置５８を装着しておくと、吸引ファン１５によってファン胴１５ａから排出される乾燥排気は、籾殻、その他の塵埃類を含んで排出されるが、接続筒５７を経由して集塵筒５９の導入口５９ａから入り排気口５９ｂから抜ける途中で、中心部に向けノズル環６１ａ，６１ｂ，６１ｃ夫々の噴口６２ａ〜６２ｆから噴出されるシャワー水を受けてこれらの塵埃類が捕捉され、シャワー水と共に連通口５９ｄから下方の遠心分離器６０に入る。この遠心分離器６０では、回転容器６７の回転で内部に入った水分が集塵バッグ７０の目合いを通過し、および該回転容器６７の通孔６７ａを通過する過程で該水分中に含まれる塵埃はその水分と分離されて集塵バッグ７０内に残ることとなる。 If the dust collector 58 is mounted on the rear side of the dryer during the drying operation, the dry exhaust discharged from the fan body 15a by the suction fan 15 is discharged including rice husks and other dusts. The shower water sprayed from the nozzle holes 61a, 61b, 61c of the nozzle rings 61a, 61b, 61c toward the center is entered on the way from the inlet 59a of the dust collecting cylinder 59 through the connecting cylinder 57 and through the exhaust port 59b. In response, these dusts are trapped and enter the lower centrifuge 60 through the communication port 59d together with the shower water. In the centrifugal separator 60, the water that has entered inside due to the rotation of the rotary container 67 passes through the mesh of the dust collection bag 70 and is contained in the water in the process of passing through the through hole 67 a of the rotary container 67. The dust is separated from the moisture and remains in the dust collection bag 70.

通孔６７ａを経由したシャワー水は、排水路を経て水槽７１に貯水される。この水槽７３の水はポンプ手段７４によってノズル環６１ａ，６１ｂ，６１ｃに還元供給され再度シャワー水として利用される。 The shower water passing through the through hole 67a is stored in the water tank 71 through the drainage channel. The water in the water tank 73 is reduced and supplied to the nozzle rings 61a, 61b, 61c by the pump means 74 and is used again as shower water.

集塵バッグ７０には捕捉された塵埃類が堆積するが、適宜の時期を見計らって遠心分離器６０本体より取り出して廃棄処分される。すなわち、脚部材７８を高くしてボルト７８ａで固定することにより、集塵筒５９を上方に持ち上げ、遠心分離器６０の蓋体６５の受筒体６５ａから集塵筒５９の筒体５９ｅを嵌合から外すと共に、接合手段６４ａをもって集合パイプ６４と各導入パイプ６３とを切り離しておくと、遠心分離器６０本体をずらせることができる。次いで蓋体６５を上方に外すことで回転容器６７を露出させることができる。この状態で係止紐７０ａを解き、集塵バッグ７０を回転容器６７ないし本体６６から取り出すことができる。集塵バッグ７０内の堆積塵埃を廃棄し、又は集塵バッグ７０毎廃棄処分し、新たに集塵バッグ７０を回転容器に装着して次回の乾燥運転に備える。 The trapped dust accumulates in the dust bag 70, but is taken out of the centrifuge 60 body and disposed of at an appropriate time. That is, by raising the leg member 78 and fixing it with the bolt 78a, the dust collecting cylinder 59 is lifted upward, and the cylinder 59e of the dust collecting cylinder 59 is fitted from the receiving cylinder 65a of the lid body 65 of the centrifuge 60. When the collecting pipe 64 and each introduction pipe 63 are separated from each other by the joining means 64a, the main body of the centrifuge 60 can be shifted. Next, the rotating container 67 can be exposed by removing the lid 65 upward. In this state, the locking string 70a is unwound and the dust collection bag 70 can be taken out from the rotary container 67 or the main body 66. The accumulated dust in the dust collection bag 70 is discarded or discarded together with the dust collection bag 70, and a new dust collection bag 70 is attached to the rotating container to prepare for the next drying operation.

上記のように、集塵バッグ７０には水分と分離された塵埃が堆積して残り、これを取り出す作業が集塵筒５９と遠心分離器６０との上下の切り離しによって容易に行なうことができ、然も遠心分離器６０から排出される水分は再利用できるものである。 As described above, dust separated from moisture is accumulated in the dust collection bag 70, and the operation of taking it out can be easily performed by vertically separating the dust collection tube 59 and the centrifuge 60, However, the water discharged from the centrifuge 60 can be reused.

上例において、集塵装置５８の運転は専用の起動スイッチ（図示せず）操作によって駆動モータ７２やポンプ手段７４を起動し、専用の停止スイッチ（図示せず）によってこれらを停止処理する構成とするが、水槽７３内の水位が低下したときは、フロートスイッチ７５がこれを検知しバルブ７７が開放状態に切り換わり蛇口からの水を補給するようになっているため、集塵装置５８の運転中、自動的に水分補充を行ない得て自動運転継続が可能であって、穀粒乾燥機のように夜間を通じた連続運転を行なう装置の場合に効果がある。 In the above example, the dust collector 58 is operated by starting the drive motor 72 and the pump means 74 by operating a dedicated start switch (not shown) and stopping them by using a dedicated stop switch (not shown). However, when the water level in the water tank 73 decreases, the float switch 75 detects this, and the valve 77 is switched to the open state so that water from the faucet is replenished. In the middle, it is possible to automatically replenish water and continue automatic operation, which is effective in the case of a device that performs continuous operation throughout the night, such as a grain dryer.

前記ノズル環６１ａ，６１ｂ，６１ｃは排気風の流通する方向に沿って複数（図例では３連）に設けてあるから、噴口６２ａ〜６２ｆからの水噴霧の範囲を拡大確保でき塵埃類の捕捉を十分に行うことができる。このノズル環６１ａ，６１ｂ，６１ｃを複数に設定し、ポンプ手段７４との関係によって必要な捕捉範囲を得ることができる。 Since the nozzle rings 61a, 61b, 61c are provided in a plurality (three in the illustrated example) along the direction in which the exhaust air flows, the range of water spray from the nozzles 62a to 62f can be ensured to be expanded, and dust can be captured. Can be done sufficiently. A plurality of nozzle rings 61 a, 61 b, 61 c are set, and a necessary capture range can be obtained depending on the relationship with the pump means 74.

前記ノズル環６１ａ，６１ｂ，６１ｃの一又は複数の夫々に配設される噴口６２ａ〜６２ｆのピッチは、上側のピッチＰｕが下側のピッチＰｄよりも狭い配列とし、捕捉の効率を高めている。 The pitches of the nozzle holes 62a to 62f arranged in one or a plurality of the nozzle rings 61a, 61b, 61c are arranged such that the upper pitch Pu is narrower than the lower pitch Pd, thereby improving the capture efficiency. .

図１１は集塵筒５９の上下動構成の改良に係るもので、集塵筒５９の前部を乾燥機のファン胴１５ａに対して可撓性接続部材５７及びリンク５７ａによって上下動可能に支持する一方、該集塵筒５９の後部側を上下すべく伸縮調整自在の脚部材８０によって支持する。この脚部材８０は、ハンドル８０ａ操作によって２重筒が伸縮しうる構成で、前記集塵バッグ７０の廃棄の際には該ハンドル８０ａで脚部材８０を高くすることによって集塵筒５９が前方を支点として後方が上昇し、遠心分離器６０の蓋体６５の受筒体６５ａから集塵筒５９の筒体５９ｅの嵌合を外すことができ、作業が容易となる。 FIG. 11 relates to an improvement in the vertical movement configuration of the dust collecting cylinder 59, and the front portion of the dust collecting cylinder 59 is supported by the flexible connecting member 57 and the link 57a with respect to the fan body 15a of the dryer. On the other hand, the rear side of the dust collection tube 59 is supported by a leg member 80 that can be expanded and contracted to move up and down. The leg member 80 is configured such that the double cylinder can be expanded and contracted by operating the handle 80a. When the dust bag 70 is discarded, the leg member 80 is raised by the handle 80a so that the dust collection cylinder 59 is moved forward. The rear part rises as a fulcrum, and the fitting of the cylinder body 59e of the dust collecting cylinder 59 can be removed from the receiving cylinder body 65a of the lid body 65 of the centrifuge 60, and the work becomes easy.

なお、図のように蓋体６５と集塵筒５９とを連結一体化することにより、集塵筒５９の上昇で蓋体６５も一挙に上昇させ得、本体内部の回転容器６７の上記作業が一層容易である。 As shown in the figure, the lid 65 and the dust collecting cylinder 59 are connected and integrated, so that the lid 65 can be raised at once by raising the dust collecting cylinder 59, and the above operation of the rotary container 67 inside the main body can be performed. It is even easier.

次に、図１２〜図１４に基づき繰出バルブ７のシール構成について説明する。 Next, the seal configuration of the feeding valve 7 will be described with reference to FIGS.

左右の穀物流下通路５，５の下端合流部下方には、断面円筒状で正転及び逆転を繰り返しながら穀粒を繰り出す円筒状の繰出バルブ７を設け、この繰出バルブ７には穀物流下通路５，５の全幅に対応する穀粒繰出用の繰出開口部７ａを構成し、繰出バルブ７の左右周面部と左右の穀物流下通路５，５の下端部との間に左・右間隙８７，８７を構成している。 Below the lower end joining part of the left and right grain flow passages 5 and 5, a cylindrical feeding valve 7 is provided which feeds the grain while repeating forward and reverse rotation in a cylindrical cross section. , 5 is provided with a feeding opening 7a for feeding the grain, and left and right gaps 87, 87 between the left and right peripheral surfaces of the feeding valve 7 and the lower ends of the left and right grain flow passages 5, 5 are formed. Is configured.

左右の穀物流下通路５，５の下端部下方で且つ繰出バルブ７の左右両側部位に断面凹状の左右のシール保持枠体８８，８８を配置している。即ち、断面Ｕ状に形成した外枠体８８ａと該外枠体８８ａに嵌合する内枠体８８ｂとを一体的に構成する。このシール保持枠体８８，８８の内側部、つまり該内枠体８８ｂの一隅部には繰出バルブ７に摺接対向するシール８９，８９を包持すべく包持体８９ａをもってボルト・ナットで着脱自在に固着している。すなわちシールはゴム製で基部側厚肉部８９ｂは包持体８９ａの嵌合凹部８９ｃに嵌合し、シールの先端側薄肉部８９ｄは繰出バルブ７の外周に摺接しうる。 Left and right seal holding frames 88, 88 having a concave cross section are disposed below the lower ends of the left and right grain flow passages 5, 5 and on the left and right sides of the feeding valve 7. That is, an outer frame 88a formed in a U-shaped cross section and an inner frame 88b fitted to the outer frame 88a are integrally configured. At the inner side of the seal holding frames 88, 88, that is, at one corner of the inner frame 88b, a holding member 89a is attached and detached with bolts and nuts so as to hold the seals 89, 89 slidably facing the feeding valve 7. It adheres freely. That is, the seal is made of rubber, the base side thick portion 89b is fitted into the fitting recess 89c of the holding body 89a, and the tip side thin portion 89d of the seal can be slidably contacted with the outer periphery of the feeding valve 7.

上記シール保持枠体８８，８８の前後両端部にはブラケット９０ａ，９０ｂを取り付け、機枠１の前・後側壁９１ａ，９１ｂの支持孔９１´ａ，９１´ｂと前記ブラケット９０ａ，９０ｂの支持孔９０´ａ，９０´ｂに前後の支持軸９３ａ，９３ｂを挿通して、このシール保持枠体８８，８８を前・後側壁９１ａ，９１ｂに回動自在に軸支する。回動軸心（イ）について前側の支持軸９３ａにアーム９４を設け、このアーム９４を前側壁９１ａの外側に沿って回動可能に構成している。前後の支持軸９３ａ，９３ｂの一端部にはアーム９４をシール保持枠体８８と一体的に設け、このアーム９４の先端部と機枠の所定個所との間に支点越えスプリング９６を設ける。９７は該スプリング９６の引張り強さを調整するアジャストボルトである。このスプリング９６の弾性力によりシール保持枠体８８，８８が前記通気性網体５ａ，５ａの下端部に接して停止保持される第１姿勢の状態（図１４中実線）と、支点越えしてシール保持枠体８８，８８を反転する第２姿勢（図１４中仮想線）とに切換できる構成である。そして上記の第１姿勢ではシール８９，８９は繰出バルブ７外周面に接し、第２姿勢ではシール８９，８９は該外周面から離脱するものである。第１姿勢において異物の噛み込みによってシール保持枠体８８に負荷がかかるとスプリング９６が伸びて該シール保持枠体８８の軸回りの回転を許容し支点越えした該スプリング９６の引張力で第２姿勢に切り換わる構成である。なお、第２姿勢はスプリング９６の自由長で静止しうるものである。上記第２姿勢でアーム９４の動きによってオンするリミットスイッチ９８（位置検出手段）を設けて異物噛み込みを報知するなどの措置を講じるものである。 Brackets 90a and 90b are attached to the front and rear end portions of the seal holding frames 88 and 88, and support holes 91'a and 91'b of the front and rear side walls 91a and 91b of the machine frame 1 and the brackets 90a and 90b are supported. The front and rear support shafts 93a and 93b are inserted into the holes 90'a and 90'b, and the seal holding frame bodies 88 and 88 are pivotally supported on the front and rear side walls 91a and 91b. An arm 94 is provided on the support shaft 93a on the front side of the rotation axis (A), and the arm 94 is configured to be rotatable along the outside of the front side wall 91a. At one end of the front and rear support shafts 93a and 93b, an arm 94 is provided integrally with the seal holding frame 88, and a fulcrum spring 96 is provided between the tip of the arm 94 and a predetermined portion of the machine frame. Reference numeral 97 denotes an adjusting bolt for adjusting the tensile strength of the spring 96. The first holding state (solid line in FIG. 14) in which the seal holding frames 88, 88 are stopped and held in contact with the lower ends of the breathable nets 5a, 5a by the elastic force of the spring 96 and beyond the fulcrum. It is the structure which can be switched to the 2nd attitude | position (virtual line in FIG. 14) which reverses seal holding frame 88,88. In the first posture, the seals 89 and 89 are in contact with the outer peripheral surface of the feeding valve 7, and in the second posture, the seals 89 and 89 are detached from the outer peripheral surface. In the first position, when a load is applied to the seal holding frame 88 due to the biting of foreign matter, the spring 96 extends to allow the rotation of the seal holding frame 88 around the axis and allow the rotation of the seal 96 to exceed the fulcrum. It is a configuration that switches to a posture. Note that the second posture can be stationary with the free length of the spring 96. In the second posture, a limit switch 98 (position detecting means) that is turned on by the movement of the arm 94 is provided to take measures such as notifying of foreign object biting.

また、上記第１姿勢において、繰出バルブ７の外周面に接するよう上記のスプリング９６が作用するが、繰出バルブ７の繰出開口部７ａがシール８９，８９に対応する範囲では、スプリング９６による圧接作用を伴うとシール８９が開口部７ａの縁部に作用することによって破損し易い。このため、シール８９部を繰出開口部７ａが通過する範囲では該シール８９を退避動させるカム部材９９をバルブ駆動軸７ｂと一体的に設け、シール８９と繰出開口部７ａとの接触を防止すべく構成する。このように構成することによって上記欠点を解消することができる（図１５）。 In the first posture, the spring 96 acts so as to come into contact with the outer peripheral surface of the feeding valve 7, but in the range where the feeding opening 7 a of the feeding valve 7 corresponds to the seals 89 and 89, the pressure contact action by the spring 96 is performed. , The seal 89 is easily damaged by acting on the edge of the opening 7a. Therefore, a cam member 99 for retracting the seal 89 is provided integrally with the valve drive shaft 7b in a range where the feed opening 7a passes through the seal 89, thereby preventing contact between the seal 89 and the feed opening 7a. Configure accordingly. By configuring in this way, the above disadvantages can be eliminated (FIG. 15).

図１６は、繰出バルブ７の改良構成について示すものである。繰出バルブを長手方向に複数分割（図例では３分割）して前部・中間・後部の繰出バルブ７Ａ，７Ｂ，７Ｃとし、夫々に繰出開口部１００Ａ，１００Ｂ，１００Ｃを備える相似形をなしている。これらは単一の駆動軸１０１に挿通され、うち前側の繰出バルブ７Ａが該支持軸１０１と一体回転すべく固着され、他はこの軸１０１に遊嵌状態に支持されている。そして前部繰出バルブ７Ａと中間繰出バルブ７Ｂとの間に、無負荷状態では位相を同じくし、回転負荷が掛かると位相のずれを許容する位相進退融通機構１０２を構成している。すなわち、位相進退融通機構１０２は、前部繰出バルブ７Ａの後面側フランジ部１０３と中間バルブ７Ｂの前面側フランジ部１０４との間に構成される。フランジ部１０３には位相の融通角度範囲２α（例えば９０度）に対応して回転方向前後にストッパ１０５ａ，１０５ｂを形成し、一方フランジ部１０４にはこのストッパ１０５ａ，１０５ｂに係止して前部繰出バルブ７Ａの回転駆動力を中間繰出バルブ７Ｂに伝達する係止凸条１０６を設けている。また、フランジ部１０３には回転方向前後に中立復帰バネ１０７，１０７を設けてなる（図１７）。 FIG. 16 shows an improved configuration of the feeding valve 7. The feeding valve is divided into a plurality of parts in the longitudinal direction (three parts in the example shown in the figure) to form front, middle and rear feeding valves 7A, 7B and 7C, which are similar in shape with feeding openings 100A, 100B and 100C, respectively. Yes. These are inserted through a single drive shaft 101, of which the front feeding valve 7A is fixed to rotate integrally with the support shaft 101, and the other is supported in a loosely fitted state on the shaft 101. A phase advance / retract mechanism 102 is configured between the front delivery valve 7A and the intermediate delivery valve 7B so as to have the same phase in the no-load state and allow a phase shift when a rotational load is applied. That is, the phase advance / retreat mechanism 102 is configured between the rear flange portion 103 of the front feeding valve 7A and the front flange portion 104 of the intermediate valve 7B. The flange portion 103 is formed with stoppers 105a and 105b in front and rear in the rotational direction corresponding to a phase accommodation angle range 2α (for example, 90 degrees), while the flange portion 104 is engaged with the stoppers 105a and 105b to be connected to the front portion. A locking projection 106 for transmitting the rotational driving force of the feeding valve 7A to the intermediate feeding valve 7B is provided. Further, the flange portion 103 is provided with neutral return springs 107, 107 in the front and rear of the rotation direction (FIG. 17).

上記位相進退融通機構１０２は中間繰出バルブ７Ｂと後部繰出バルブ７Ｃとの間にも構成される。 The phase advance / retreat mechanism 102 is also configured between the intermediate delivery valve 7B and the rear delivery valve 7C.

このように構成された繰出機構は、繰出開口部１００Ａ，１００Ｂ，１００Ｃが揃った状態で下向きに停止された状態から、起動出力によって駆動軸１０１が正・逆回転すると、前部・中間・後部繰出バルブ７Ａ，７Ｂ，７Ｃが一体的に回転して繰出開口部１００Ａ，１００Ｂ，１００Ｃが上向いて穀粒を受ける。そのまま駆動軸１０１の回転で同方向に回転しようとするが、穀粒の受け入れに伴って回転負荷が掛かり、まず駆動軸１０１と一体の前部繰出バルブ７Ａが引き続き回転でき、中間繰出バルブ７Ｂ、後部繰出バルブ７Ｃは駆動軸１０１と一体でないため、穀粒負荷によって停滞しようとするが前部繰出バルブ７Ａとの位相のずれが角度α（４５度（９０度の１／２））となると係止凸条１０６が復帰バネ１０７に抗してストッパ１０５ａに接当する状態で回転駆動力が伝達され中間繰出バルブ７Ｂが位相遅れで回転する。同様に後部繰出バルブ７Ｃは、中間繰出バルブ７Ｂよりも角度α（４５度）の位相遅れで回転連動される（図１６（イ））。このような作用が行われるため、一挙に前後幅一杯に穀粒を受け入れた状態で一挙に回転連動させるものに比較して１／３ずつの駆動負荷を越えればよいため駆動負荷を分散でき、異常過負荷による故障を防止できる。また、作業終了で駆動を停止するときは図外の回転位置検出センサによって駆動軸１０１を前部繰出バルブ７Ａの繰出開口部１００Ａが下向く姿勢で停止すべく出力させるが、このときには中間繰出バルブ７Ｂの繰出開口部１００Ｂ及び後部繰出バルブ７Ｃの繰出開口部１００Ｃも位相を遅れて追随しながら下方に穀粒排出できるため、負荷が軽減され各復帰バネ１０７の作用で前部・中間・後部の繰出開口部が揃う下向き姿勢で停止することができる（図１６（ロ））。なお、この作用は逆転連動に際しても同様に行われるものとなる。 When the driving shaft 101 is rotated forward / reversely by a start output from a state where the feeding openings 100A, 100B, 100C are aligned and stopped downward from the state where the feeding openings 100A, 100B, 100C are aligned, the feeding mechanism configured in this way The feeding valves 7A, 7B, and 7C rotate integrally, and the feeding openings 100A, 100B, and 100C face upward to receive the grain. The rotation of the drive shaft 101 continues to rotate in the same direction, but a rotational load is applied as the grain is received. First, the front feed valve 7A integral with the drive shaft 101 can continue to rotate, and the intermediate feed valve 7B, Since the rear feeding valve 7C is not integral with the drive shaft 101, the rear feeding valve 7C tries to stagnate due to the grain load, but the phase shift with the front feeding valve 7A becomes an angle α (45 degrees (1/2 of 90 degrees)). The rotational driving force is transmitted in a state where the stop ridge 106 contacts the stopper 105a against the return spring 107, and the intermediate feed valve 7B rotates with a phase delay. Similarly, the rear feeding valve 7C is rotationally interlocked with a phase delay of an angle α (45 degrees) with respect to the intermediate feeding valve 7B (FIG. 16 (A)). Since such an action is performed, the drive load can be dispersed because it is sufficient to exceed the drive load of 1/3 each compared to the one that is rotated and interlocked at once in a state where the grain is accepted at once in the front and rear width, Failure due to abnormal overload can be prevented. Further, when the drive is stopped at the end of the work, the drive shaft 101 is output by a rotational position detection sensor (not shown) so as to stop in a posture in which the feed opening portion 100A of the front feed valve 7A faces downward. Since the feeding opening 100B of the 7B and the feeding opening 100C of the rear feeding valve 7C can follow the phase with a delay, the grain can be discharged downward, so that the load is reduced and the action of each return spring 107 causes the front, middle and rear parts to be discharged. It is possible to stop in a downward posture in which the feeding openings are aligned (FIG. 16B). This action is performed in the same way when the reverse rotation is interlocked.

以上のように、繰出バルブを複数に区分してこのうち所定の繰出バルブを駆動軸に一体化し、他は繰出バルブとの間で位相進退融通機構を構成することで各繰出バルブの繰出開口部の位相をずらせて穀粒を送り、空の状態で位相が揃うように復帰させることによって起動負荷を低減し、あわせて作業待機時は復帰バネで繰出開口部の位相を揃えることができる。 As described above, the feeding valve is divided into a plurality of parts, and among these, a predetermined feeding valve is integrated with the drive shaft, and the others are configured with a phase advance / retreat mechanism between the feeding valves, thereby feeding openings of each feeding valve. The starting load can be reduced by returning the grains so that the phases are aligned in the empty state, and the phases of the feeding openings can be aligned by the return springs during standby.

なお、繰出バルブの複数区分形態において、当初から前部・中間・後部の各繰出バルブの繰出開口部の位相をずらせて駆動軸に装着するように構成し、停止状態でこのうちの一の繰出開口部が上向くよう回転制御すると、乾燥機への穀粒張込後、乾燥のために繰出バルブを起動する際、この上向き繰出開口部に穀粒が堆積状態となるだけであるから起動時に掛かる負荷が低減できるため、異常過負荷を防止する。 In addition, in the multiple division form of the supply valve, it is configured so that the phases of the supply opening portions of the front, middle, and rear supply valves are shifted from the beginning to be mounted on the drive shaft, and one of these is supplied in the stopped state. When the rotation control is performed so that the opening is directed upward, when the feeding valve is started for drying after the grain is put into the dryer, the grain is only accumulated in the upward feeding opening so that it takes time to start. Since the load can be reduced, abnormal overload is prevented.

図５において機体後部の壁面に火炎監視用の鏡体１０８を構成している。このガラス体１０８は遠赤外線放射体後部に対応する壁面に設けられ、正面側からのぞくと鏡体１０８にバーナの火炎が映し出されて着失火の確認や、火炎色の適否を判断できることを目的とするが、この鏡体１０８には光触媒をコーティング処理している。即ち酸化チタンの粉末をコーティング液にてコーティング処理するか、予めコーティング処理された市販ガラスを用いる。酸化チタンはバーナ燃焼による紫外線を受けて超親水性を呈し、鏡体１０８面を超親水性表面となすため、水滴が広がり曇りを防止して長時間の使用においても継続して上記の火炎確認を精度良く行うことができる。 In FIG. 5, a flame monitoring mirror 108 is formed on the wall at the rear of the machine body. This glass body 108 is provided on the wall surface corresponding to the rear part of the far-infrared radiator, and when viewed from the front side, the flame of the burner is projected on the mirror body 108, so that it is possible to confirm the misfire and determine the suitability of the flame color. However, this mirror body 108 is coated with a photocatalyst. That is, titanium oxide powder is coated with a coating solution, or commercially available glass that has been coated in advance is used. Titanium oxide is superhydrophilic when exposed to ultraviolet rays from burner combustion, and the mirror surface 108 becomes a superhydrophilic surface, preventing water droplets from spreading and preventing fogging. Can be performed with high accuracy.

また、電子の移動により触媒面に接触した悪臭や細菌類を酸化と還元で分解するＣＴ（Charge transfer:電荷移動型自動参加還元半導体）触媒を乾燥機等の農業機械に施すことによって防汚に効果がある。このＣＴ触媒はスプレー式で噴霧しうるものを採用し、穀粒乾燥機の例では穀粒通路を形成する部分や螺旋やバケット等の移送手段に噴霧して用いることによって、防汚のほか、消臭、除菌の効果を得ることができる。特に上記光触媒に比較して紫外線を必要とせず、光の当たらない暗い場所にても有効であるため、倉庫に設置されて動かせる機会の少ない装置類に効果的である。 In addition, anti-fouling can be achieved by applying CT (Charge Transfer: Charge Transfer Type Automatic Participation Reduction Semiconductor) catalyst to agricultural machinery such as dryers, which decomposes bad odors and bacteria contacting the catalyst surface by oxidation and reduction by oxidation and reduction. effective. This CT catalyst adopts a spray type that can be sprayed, and in the example of a grain dryer, in addition to antifouling, by spraying and using the part that forms the grain passage and the transfer means such as a spiral or bucket, Deodorizing and sterilizing effects can be obtained. In particular, it does not require ultraviolet light as compared with the photocatalyst, and is effective even in a dark place where no light is applied. Therefore, it is effective for devices installed in a warehouse and having few opportunities to move.
