Description

本発明は、循環流下する穀物に熱風を通過させて穀物を乾燥する、穀物乾燥装置に関する。   The present invention relates to a grain drying apparatus for drying grain by passing hot air through the circulated grain.

従来、前後方向に長い角筒状の乾燥装置本体内の集穀部の両側の一方を熱風送風室、そしてもう一方を排塵風室とし、乾燥機の短辺となる左右方向に、熱風送風室に通ずる複数の熱風室と排塵風室に通ずる複数の排風室とを両室間に巾狭の乾燥通路を形成されるよう交互に架設した構成は、特開昭５７−１０４０７８号公報（特許文献１）に記載されている。   Conventionally, a hot air blower is used in the horizontal direction, which is the short side of the dryer. Japanese Patent Application Laid-Open No. 57-104078 discloses a configuration in which a plurality of hot air chambers communicating with a chamber and a plurality of exhaust air chambers communicating with a dust exhaust air chamber are alternately laid to form a narrow drying passage between the two chambers. (Patent Document 1).

また、上記特許文献１の構成に、熱風室、乾燥通路、排風室を配置した乾燥部の直下に乾燥装置の長辺となる前後方向に複数配置した山形仕切壁により形成された複数列の交差流下繰出し室の下部に前後方向に回転自在に軸架した繰出しロールによって穀物を定量的に繰出し、繰出しロールの周囲を熱風送風室、排塵風室および繰出し室で囲まれた構成となった穀物乾燥機は特開昭６１−５５０３７号公報のように公知となっている。   In addition, in the configuration of Patent Document 1, a plurality of rows of mountain-shaped partition walls formed in the front-rear direction, which is the long side of the drying device, are directly below the drying unit in which the hot air chamber, the drying passage, and the exhaust air chamber are disposed. Grains are quantitatively fed out by a feed roll that is pivotally supported in the lower part of the cross-flow feed chamber in the front-rear direction, and the periphery of the feed roll is surrounded by a hot air blowing chamber, a dust exhaust chamber, and a feeding chamber. A grain dryer is known as disclosed in JP-A-61-55037.

特開昭５７−１０４０７８号公報Japanese Patent Laid-Open No. 57-104078 特開昭６１−０５５０３７号公報JP 61-055037 A

上記文献を実施した穀物乾燥機においては、乾燥通路を巾狭としているにも係わらずその乾燥通路の表面積を広く確保することが出来るので、効率よくしかも均一に穀物が流下することが出来るので、穀物の均一の乾燥を実現することが出来ている。また乾燥通路が巾狭であるので通風抵抗が少なく、無理なく穀物層の通風を行うことが出来るので、送風機の動力を小さくしても有効に通風できることを可能としている。   In the grain dryer that implements the above document, the surface area of the drying passage can be secured widely despite the narrowness of the drying passage, so that the grain can flow efficiently and uniformly, Uniform drying of the grain can be realized. In addition, since the drying passage is narrow, the resistance to ventilation is low and the grain layer can be ventilated without difficulty. Therefore, it is possible to effectively ventilate even if the power of the blower is reduced.

しかしながら上記構成において、排塵風室の側面壁が外気に接していて、排風が通過しにくい排塵風室の一部では塵埃が堆積し、乾燥物の水分が多い場合の排風に多くの水分を含んでいるので、外気との温度差によって結露が発生して塵埃の腐敗を促進し、側面壁の腐食の発生現状が確認されている。   However, in the above configuration, the side wall of the dust exhaust chamber is in contact with the outside air, and dust accumulates in a part of the dust exhaust chamber that is difficult for the exhaust air to pass through. Therefore, condensation is generated due to a temperature difference from the outside air to promote the decay of dust, and the occurrence of side wall corrosion has been confirmed.

また、近年の農業改革において大規模農業が奨励され、集団化、企業化が促進される中で大型の穀物乾燥機の要望が高まってきているのが現状である。こうした要望にこたえるため大型の穀物乾燥機の開発に着手する必要があるのだが、上記特許文献の乾燥部を備えた穀物乾燥機においては、乾燥部の大型化では次のような不具合が発生する場合がある。   In recent years, large-scale agriculture has been encouraged in recent agricultural reforms, and the demand for large-sized grain dryers has been increasing as grouping and commercialization are promoted. In order to meet these demands, it is necessary to start development of a large grain dryer. However, in the grain dryer equipped with the drying section of the above patent document, the following problems occur when the drying section is enlarged. There is a case.

第一に、左右方向の乾燥部の延長化による乾燥通路の幅の均一化を維持が困難になるため、乾燥通路が場所によって薄厚が発生して、均一の通風と、穀物の均一な流下を損なうこととなり、穀物の乾燥を均一に行うことが出来なくなる可能性がある。   First, since it becomes difficult to maintain a uniform width of the drying passage by extending the drying section in the left-right direction, the drying passage is thin depending on the location, and uniform ventilation and uniform grain flow are achieved. And the grain may not be dried uniformly.

第二に、乾燥機自体を大きくすることは、乾燥機の貯留槽に貯留する穀物の量が多くなり、乾燥部に加わる重量も増すこととなる。特に乾燥部自体を前後若しくは左右及びその両方の方向に延長させた場合においては、乾燥部に加わる重量に耐え、乾燥部の変形を防ぐために、乾燥部に使われる部材の厚さを増すか、重量に耐えうる構造に変更を余儀なくされ、従前に使用されている乾燥部の長さを延長するだけでは、その機能を果たさない結果となってしまう。また部材を厚くする、または荷重に耐える乾燥部の構造の新設計はコスト的に問題となり、商品価格の高騰をまねく結果となる。   Secondly, increasing the size of the dryer itself increases the amount of grain stored in the storage tank of the dryer and increases the weight applied to the drying section. In particular, in the case where the drying unit itself is extended in the front-rear or left-right direction and both directions, the thickness of the member used in the drying unit is increased in order to withstand the weight applied to the drying unit and prevent deformation of the drying unit, A structure that can withstand the weight is inevitably changed, and simply extending the length of the drying section that has been used before does not perform its function. Moreover, the new design of the structure of the dry part which can increase the thickness of the member or withstand the load is a problem in terms of cost, resulting in a rise in the product price.

第三に、乾燥部の大型化を行うことによって、乾燥部を通過する乾燥風の流れの不具合をきたし、通風しやすい場所と滞留しやすい場所の格差を増し、排塵風室に塵埃の堆積を増すばかりか、穀物を均一に乾燥する乾燥機の目的の達成が困難になる可能性があるので、乾燥部のそれぞれの場所に均一に乾燥風を通風するような装置を必要とするため、乾燥機自体のコストを高める結果となるものである。   Third, by increasing the size of the drying section, the flow of drying air that passes through the drying section has become defective, increasing the gap between places where ventilation is easy and where it is likely to stay, and accumulation of dust in the dust exhaust chamber. In addition, it may be difficult to achieve the purpose of the dryer that uniformly dries the grains, so it is necessary to have a device that uniformly blows the drying air at each location of the drying section. This results in an increase in the cost of the dryer itself.

そこで本発明では、上記の不具合を解消するように、乾燥部自体を大きく構成しても、部材の厚さを増す方法や、強度を増す構造を新たに設計しなくても従来の乾燥部の構造を利用して、荷重に耐え均一な乾燥通路の幅を保って、乾燥風の乾燥通路の通風と穀物の均等な流下を可能とした乾燥部を提供すると共に、均一に乾燥風を乾燥通路と排風室と排塵風室に供給を行い、排塵風室内の通風の滞留を防止して、排塵風室内の塵埃の堆積を低減した穀物乾燥装置を提供することを目的とする。   Therefore, in the present invention, in order to eliminate the above-mentioned problems, even if the drying unit itself is configured to be large, the method of increasing the thickness of the member or the structure for increasing the strength is not newly designed. Utilizing the structure to provide a drying section that can withstand the load and maintain a uniform width of the drying path, allowing the drying air to pass through the drying path and flowing the grain evenly, and uniformly drying the drying path Another object of the present invention is to provide a grain drying apparatus that supplies the exhaust air chamber and the exhaust air chamber, prevents the accumulation of ventilation in the exhaust air chamber, and reduces the accumulation of dust in the exhaust air chamber.

As the left and right ends of the layer become lower, two dried bodies 6 having an inverted conical shape are arranged side by side in parallel, and a space generated by the inverted cone shape of the left and right side plate surfaces of the grain drying device and the dried body is dried by wind. The drying unit 3 is formed with the supply cylinder 30 and a space generated in an inverted conical shape between the drying bodies 6 as the exhaust cylinder 31. In addition, each layer crossing the dry body 6 in the left-right direction is the hot air layer 7 if the layer in contact with the front side plate of the drying apparatus is the hot air layer 7, and the layer in contact with the front side plate is also excluded as the last layer in contact with the rear side plate.

The space of the cylinder 30 and the exhaust wind drum 31 is extended in the vertical direction to increase the distribution space for the grains.

乾燥体６は図３に示すように、乾燥部３の前面に接する層が排風層９となりその後ろが乾燥層８、その後ろが熱風層７となって、最後層が排風層９となるように構成し、熱風層７を４つ、乾燥層８を８つ、排風層９が５つになるように構成されている。なおこの層の配列を熱風層７から配置してもよく、その場合は、熱風層７を５つ、乾燥層８を８つ、排風層９を４つの構成としてもよい。このようにそれぞれの層の配置をした乾燥体を二つ並列に配置し、一方の乾燥体６を１８０°反転して配置することによって、熱風層７、乾燥層８、排風層９が対向して配置されるようになっている。   As shown in FIG. 3, the dry body 6 has a layer in contact with the front surface of the drying unit 3 as an exhaust layer 9, a rear layer 8, a rear layer 8 as a hot air layer 7, and a final layer as the exhaust layer 9. The configuration is such that there are four hot air layers 7, eight dry layers 8, and five exhaust layers 9. The arrangement of the layers may be arranged from the hot air layer 7, and in that case, the hot air layer 7, the dry layer 8, and the exhaust layer 9 may have four structures. The two dry bodies with the respective layers arranged in this manner are arranged in parallel, and one of the dry bodies 6 is inverted 180 ° so that the hot air layer 7, the dry layer 8, and the exhaust air layer 9 face each other.

集穀部４は集穀流下路１２がそれぞれの乾燥体６の下端に備えられている。図１、２及び図４で表される乾燥体６は並列に一方が反転して排風胴３１を挟んで配置されているので、集穀流下路１２も並列に排風室１１の空間を空けて集穀部４に配置されている。この集穀流下路１２はその内部に繰出しロール１９を複数配置し、流下する穀物を繰出しロール１９に滞りなく導くように山形仕切２６が備えられていて、繰出しロール１９から排出された穀物は集穀流下路１２の斜面を流下し、集穀装置１４のスクリューコンベアに流れ込むようになっている。この繰出しロール１９はモータ（図示せず）によって回転し、それぞれの集穀流下路１２の単位にモータを設けてそれぞれを駆動するか、または全ての繰出しロール１９をチェーンで接続し、一つのモータで駆動させる方法でもよい。   In the grain collecting unit 4, a grain collecting flow path 12 is provided at the lower end of each dry body 6. Since the dried body 6 shown in FIGS. 1, 2 and 4 is arranged so that one of the dried bodies 6 is reversed in parallel and sandwiches the wind exhaust drum 31, the cereal collecting flow path 12 is also disposed in parallel in the space of the exhaust chamber 11. It is arranged in the cereal collection unit 4 in an empty space. The cereal collecting flow path 12 has a plurality of feeding rolls 19 disposed therein, and is provided with a mountain-shaped partition 26 so as to guide the flowing cereals to the feeding roll 19 without delay. Grains discharged from the feeding roll 19 are collected. It flows down the slope of the grain flow down path 12 and flows into the screw conveyor of the grain collecting device 14. The feeding roll 19 is rotated by a motor (not shown), and a motor is provided for each cereal collecting flow path 12 to drive each, or all the feeding rolls 19 are connected by a chain, and one motor The method of driving by may be used.

集穀流下路１２の集穀装置１４に至るまでの両側の斜面の一方は、斜面の一部を二重にして空間を設け、その空間を排塵通路１７として形成しており、集穀流下路１２内で発生する塵埃やゴミ等の穀物より比重が軽い物が集穀流下路１２から排出されるようになっていて、並列した集穀流下路１２の一方も乾燥体６と同様に１８０°反転して、排塵通路１７が対向して配置されるようになっている。   One of the slopes on both sides up to the grain collecting device 14 of the grain collecting downstream 12 is provided with a space by duplicating a part of the slope, and the space is formed as a dust passage 17. Items having a lighter specific gravity than grains such as dust and dirt generated in the path 12 are discharged from the cereal collecting flow path 12, and one of the parallel cereal collecting flow paths 12 is 180 as in the case of the dry body 6. Inverted, the dust passage 17 is arranged to be opposed.

集穀部４の下方はその左右方向を熱風室１０とし、中央を排風室１１となっており、左右のそれぞれの熱風室１０には液体燃料の燃焼による燃焼装置１５が配置され、その位置は乾燥装置前後方向の中央を対称とした位置に設けられており、排風室１１には２台の送風機１６が備えられている。熱風室１０の上方は乾燥風供給胴３０と連通し、排風室１１は排風胴３１と排塵通路１７に連通されている。   Below the grain collecting unit 4, the left and right direction is a hot air chamber 10, and the center is an exhaust air chamber 11. In each of the left and right hot air chambers 10, a combustion device 15 by combustion of liquid fuel is arranged, and the position thereof Is provided at a position symmetric with respect to the center in the front-rear direction of the drying apparatus, and the air exhaust chamber 11 is provided with two fans 16. The upper part of the hot air chamber 10 communicates with the dry air supply cylinder 30, and the exhaust air chamber 11 communicates with the exhaust air cylinder 31 and the dust passage 17.

揚穀装置５は内部をバケット２３を備えるベルトが一方向に回転して穀物を上部に搬送するバケット昇降機であって、穀物乾燥装置１の前後方向に対する中央で、乾燥装置の前面から若干の距離をおいて備えられている。この揚穀装置５のバケット昇降機の下部には、集穀部４の集穀装置１４のスクリューコンベアで集穀した穀物をバケット昇降機内に投入するための張り込み口１８が左右両方向に取り付けられており、それぞれの集穀装置１４からの穀物が投入できるようになっている。なお、張り込み口１８は外部から穀物乾燥装置１内に穀物を投入する場合のホッパーとして使用されるとよい。   The cerealing device 5 is a bucket elevator in which a belt provided with a bucket 23 rotates in one direction and conveys cereals to the upper part, and is at a distance from the front of the drying device at the center of the cereal drying device 1 in the front-rear direction. Is provided. In the lower part of the bucket elevator of this cerealing device 5, a filling port 18 for putting the grains collected by the screw conveyor of the cerealing device 14 of the cerealing unit 4 into the bucket elevator is attached in both the left and right directions. The grains from the respective grain collecting devices 14 can be input. In addition, it is good for the sticking mouth 18 to be used as a hopper when throwing a grain into the grain drying apparatus 1 from the outside.

揚穀装置５は上部のモータ２２からの動力で回転して穀物を上方に搬送し、その排出口は、張り込み装置１３の受入口と接合されていて、その受入口の下端には排出シュート３４が備えられ、穀物を乾燥装置の外部にここから排出することが出来るように、受入口のシャッタを設けて穀物の機内循環と、機外排出を選択することができる。張り込み装置１３はモータ３２によって螺旋を回転させて穀物を移動させるスクリューコンベアであって、張り込み装置１３のその受入口を基点として、乾燥装置の縦方向の中央線３３に接する方向で、斜め後方に角度を持って備えられている。   The cerealing device 5 is rotated by power from the upper motor 22 to convey the grain upward, and its discharge port is joined to the receiving port of the embedding device 13, and a discharge chute 34 is provided at the lower end of the receiving port. In order to allow the grain to be discharged from the outside of the drying apparatus, a shutter at the receiving port can be provided to select the in-machine circulation and the outside discharge of the grain. The tensioning device 13 is a screw conveyor that rotates a helix by a motor 32 to move the grain, and obliquely rearward in a direction that is in contact with the vertical center line 33 of the drying device, with the receiving port of the tensioning device 13 as a base point. It is provided with an angle.

張り込み装置１３の底部と貯留槽２の天井面には螺旋の回転によって搬送される穀物を、貯留槽２内に投入するための投入口Ａ２０と投入口Ｂ２１を配置されており、この投入口はその開度をそれぞれ調節して投入の量を調節することができるようになっている（図５参照）。   An insertion port A20 and an insertion port B21 are disposed on the bottom of the embedding device 13 and the ceiling surface of the storage tank 2 to input the grains conveyed by spiral rotation into the storage tank 2. The opening amount can be adjusted to adjust the amount of charging (see FIG. 5).

さらに図６に示すように、揚穀装置５のバケット昇降機のモータ２２を備えた上部だけを１８０°反転させて備えることも出来るように構成しているので、張り込み装置１３は中央線３３を基線として対称位置に備えられるようになっていて、張り込み装置１３から貯留槽２内に投入するための投入口Ｃ２４と投入口Ｄ２５が備えられている。なお、揚穀装置５の上部の方向によって張り込み装置１３が設置されない投入口が発生するので、使用されていない投入口には蓋が取り付けられ閉じられているものである。   Further, as shown in FIG. 6, since only the upper part of the cerealing device 5 having the bucket lift motor 22 can be inverted by 180 °, the tensioning device 13 has a base line 33 as a base line. Are provided at a symmetrical position, and are provided with a loading port C24 and a loading port D25 for loading into the storage tank 2 from the tensioning device 13. In addition, since the insertion port where the tensioning device 13 is not installed is generated depending on the direction of the upper portion of the cerealing device 5, a lid is attached to the unused insertion port and closed.

以上のように構成された穀物乾燥装置において、収穫後の穀物を搬送機によって張り込み口１８に投入され、揚穀装置５のバケット昇降機によって上方に搬送されて、その排出口から張り込み装置１３に移動し螺旋の回転によって、張り込み装置１３の前方から斜め後方に向かって搬送され、投入口Ａ２０と投入口Ｂ２１から貯留槽２内に投入される。   In the grain drying apparatus configured as described above, the harvested grain is introduced into the filling port 18 by the transporter, transported upward by the bucket elevator of the cerealing device 5, and moved from the discharge port to the pasting device 13. By the rotation of the spiral, it is conveyed from the front side of the tensioning device 13 toward the oblique rear side, and is fed into the storage tank 2 from the charging port A20 and the charging port B21.

通常の揚穀装置の排出方向が図５であるとすると、穀物は投入口Ａ２０と投入口Ｂ２１から貯留槽２内に投入されるが、乾燥の後工程の方向によっては図６のように揚穀装置５の向きを変える必要があるので、その場合は揚穀装置５（バケット昇降機）の上部を１８０°反転させ、バケットを取り付けたベルトの向きも反転させて設置し、張り込み装置１３も中央線３３を基線にして対称方向に向け、揚穀装置５の排出口と接続して投入口Ｃ２４と投入口Ｄ２５を開口し、投入口Ａ２０と投入口Ｂ２１に蓋をして閉じるようにする。   Assuming that the normal cerealing device discharge direction is as shown in FIG. 5, the cereal is input into the storage tank 2 from the input port A20 and the input port B21. Since it is necessary to change the direction of the cereal device 5, in that case, the upper part of the cerealing device 5 (bucket elevator) is inverted 180 °, the direction of the belt to which the bucket is attached is also inverted, and the tensioning device 13 is also in the center. With the line 33 as a base line, it is connected to the discharge port of the cerealing device 5 to open the input port C24 and the input port D25, and the input port A20 and the input port B21 are covered and closed.

穀物乾燥装置の張込操作においては、揚穀装置５に備える張り込み口１８のどちらから一方若しくは両方から投入される穀物が、揚穀装置５によって張り込み装置１３に達し、二つの投入口（Ａ，Ｂ若しくはＣ、Ｄ）から投入され、穀物が貯留槽２内に堆積される。この張込操作は集穀部４に備える繰出ロール１９を動作させないので、貯留槽２内に二つの山を築いて貯留槽内をほぼ均一に穀物が堆積する。   In the tensioning operation of the grain drying device, the grain input from one or both of the tensioning ports 18 provided in the cerealing device 5 reaches the tensioning device 13 by the mashing device 5, and the two inlets (A, B or C, D) and the grains are deposited in the storage tank 2. Since this stretching operation does not operate the feeding roll 19 provided in the cereal collecting unit 4, two piles are built in the storage tank 2 and the grains are deposited almost uniformly in the storage tank.

張込操作終了後、次いで乾燥操作によって集穀部４の繰出しロール１９が回転を開始し、穀物の流下及び循環が開始される。二つの乾燥体６に取り付けられた二つの繰出しロール１９は均一に穀物を流下させるので、それぞれの乾燥体６を流下する穀物の流下速度も同一となる。さらに図３、図４に示すように、送風機１６を２台を集穀部４の排風室１１に配置して、乾燥装置の左右方向に備えた二つの熱風室１０のそれぞれの燃焼装置１５で発生した熱風を送風機１６の吸引作用によってそれぞれの乾燥風供給路３０を上昇して乾燥体６に供給される。   After completion of the tensioning operation, the feeding roll 19 of the cereal collecting unit 4 starts rotating by the drying operation, and the grain flow and circulation start. Since the two feeding rolls 19 attached to the two dry bodies 6 allow the grains to flow uniformly, the flow speeds of the grains flowing down the respective dry bodies 6 are also the same. Further, as shown in FIGS. 3 and 4, the two blowers 16 are arranged in the air exhaust chamber 11 of the grain collecting unit 4, and the respective combustion devices 15 of the two hot air chambers 10 provided in the left-right direction of the drying device. The hot air generated in step S <b> 1 is raised by the suction action of the blower 16 and is supplied to the dry body 6 through the respective dry air supply paths 30.

二つの乾燥体６は１８０°反転して備えられているので、熱風層７と乾燥層８と排風層９のそれぞれが対向して配列されることとなり、送風機１６からの隣り合う二つの乾燥体６の対向する排風層９までの距離と、燃焼装置１５とそれぞれの熱風層７までの距離が同一であるので、それぞれの層の風速、風量を同一とすることが出来る。例えば一方の乾燥体６を反転しないで配置した場合、それぞれの層と送風機１６、燃焼装置１５との風の流通距離が異なるので乾燥層８に通風される乾燥風がそれぞれの乾燥体６で異なる。特にそれぞれの排風層９と送風機１６の距離が二つの乾燥体６で異なった場合には排風室９内で乱流が発生してそれぞれの乾燥層８の通風量が異なる現象が発生し、均一の乾燥が困難となる。   Since the two drying bodies 6 are provided by being inverted 180 °, the hot air layer 7, the drying layer 8, and the exhaust air layer 9 are arranged to face each other, and two adjacent drying units from the blower 16 are arranged. Since the distance to the exhaust air layer 9 facing the body 6 and the distance to the combustion device 15 and each hot air layer 7 are the same, the wind speed and air volume of each layer can be made the same. For example, when one of the dry bodies 6 is arranged without being inverted, the air flow distance between each layer, the blower 16 and the combustion device 15 is different, so that the dry air passed through the dry layer 8 is different for each dry body 6. . In particular, when the distance between each exhaust layer 9 and the blower 16 is different between the two dry bodies 6, turbulent flow is generated in the exhaust chamber 9 and a phenomenon occurs in which the air flow rate of each dry layer 8 is different. Uniform drying becomes difficult.

乾燥部を通過した穀物は、集穀部４のそれぞれの乾燥体６に接続された集穀流下路１２の複数の山形仕切２６によって繰出しロール１９方向に導き、繰出しロール１９の回転で均一に定量的に集穀流下路１２の斜面に排出される。この場合、図４に示すように集穀流下路１２の一方の斜面には排塵通路１７が設けられ、二つの集穀流下路１２のそれぞれの排塵通路１７が対向して排風室１１に設けられているので、熱風室１０で発生する乾燥風が熱風供給胴３０から熱風層７を通過して乾燥層８に達した時に、その一部の乾燥風が乾燥層８を縦方向に通風され山形仕切２６のから繰出しロール１９を通過して集穀流下路１２の排塵通路１７から排風室１１に至って、送風機１６から機外に排出される。この排塵通路１７を通過する乾燥風は、集穀流下路１２を流下する穀物を若干乾燥すると同時に、繰出しロール１９から散粒状に穀物を流下することによって発生する塵埃を吸引し、機外に排出されるようになっている。   Grains that have passed through the drying section are guided in the direction of the feeding roll 19 by a plurality of mountain-shaped partitions 26 of the grain collection flow path 12 connected to the respective dried bodies 6 of the grain collection section 4, and are uniformly quantified by the rotation of the feeding roll 19. Thus, it is discharged to the slope of the cereal collecting downstream 12. In this case, as shown in FIG. 4, the dust collecting passage 17 is provided on one slope of the cereal collecting flow path 12, and the dust collecting passages 17 of the two cereal collecting flow paths 12 face each other, and the air discharge chamber 11. When the dry air generated in the hot air chamber 10 passes through the hot air supply cylinder 30 and reaches the dry layer 8, a part of the dry air passes through the dry layer 8 in the vertical direction. The air is ventilated, passes through the feeding roll 19 from the angle partition 26, reaches the exhaust chamber 11 from the dust passage 17 of the cereal collecting downstream 12, and is discharged from the blower 16 to the outside. The dry air passing through the dust passage 17 slightly dries the grains flowing down the cereal collecting flow path 12, and at the same time sucks the dust generated by flowing the grains down from the feeding roll 19 to the outside of the machine. It is supposed to be discharged.

排塵通路１７が集穀流下路１２に排風室１１の空間を挟んで対向して同じ位置に設けられているので、二つの排塵通路１７から均一に吸引することを可能として、排風室１１内に乱流を発生させることなく、排風室１１内に塵埃の堆積を最小限に抑えることが出来る効果を有している。   Since the dust exhaust passage 17 is provided at the same position so as to face the cereal collecting flow path 12 across the space of the air exhaust chamber 11, the dust exhaust passage 17 can be uniformly sucked from the two dust exhaust passages 17. This has the effect of minimizing dust accumulation in the exhaust chamber 11 without generating turbulence in the chamber 11.

集穀流下路１２を流下した穀物は、排塵通路１７で除塵作用を受けその後、その下端に配置した集穀装置４で揚穀装置５方向に集められ、張り込み口１８から揚穀装置５に投入され穀物乾燥装置１内を循環し、設定の水分値まで乾燥の後、排出シュート３４から排出されて後工程の作業へ移行する。   Grains that have flowed down the cereal collecting flow path 12 are dust-removed in the dust passage 17, and then collected in the direction of the cerealing device 5 by the cerealing device 4 arranged at the lower end thereof. It is then circulated in the grain drying apparatus 1 and dried to a set moisture value, and then discharged from the discharge chute 34 and transferred to a post-process operation.

図７は本発明の第二の実施の形態を示す乾燥部３の断面略図であって、燃焼装置１５と送風機１６をそれぞれ一つにした構成を表すものであって、乾燥部３以外の構成は、実施例１に示す構成と同等である。   FIG. 7 is a schematic cross-sectional view of the drying unit 3 showing the second embodiment of the present invention, and shows a configuration in which the combustion device 15 and the blower 16 are combined, and the configuration other than the drying unit 3 Is equivalent to the configuration shown in the first embodiment.

乾燥部３には乾燥体６を二つ左右方向に並列に配置し、一方の乾燥体６を１８０°反転して備えている。またそれぞれの層の配列も、左右方向を横断する熱風層７、乾燥層８、排風層９若しくは排風層９、乾燥層８、熱風層７の順に前後方向に繰り返し配置し、それぞれの層の左右両端は下方になるにつれて逆円錐形状を成した乾燥体６を左右方向に二つ配置して、穀物乾燥装置の外周面と乾燥体の逆円錐形状で発生する空間を乾燥風供給胴３０とし、乾燥体６同士の逆円錐形状で発生する空間を排風胴３１として、乾燥部３を形成している。なお、乾燥体を左右方向に横断するそれぞれの層は、乾燥体６の前方が熱風層７であれば最後層も熱風層７とし、乾燥体６の前方が排風層９であれば、最後層は排風層９になるように構成されている。   The drying unit 3 includes two drying bodies 6 arranged in parallel in the left-right direction, and one drying body 6 is inverted 180 °. In addition, the arrangement of the respective layers is also repeatedly arranged in the front-rear direction in the order of the hot air layer 7, the dry layer 8, the exhaust air layer 9 or the exhaust air layer 9, the dry layer 8, and the hot air layer 7 that traverse in the left-right direction. Two drying bodies 6 having an inverted conical shape are disposed in the left-right direction as the left and right ends of the drying apparatus are lowered, and a space generated by the outer cone of the grain drying device and the inverted cone shape of the drying body is provided as a drying wind supply cylinder 30. The drying unit 3 is formed with the space generated in the inverted conical shape between the dry bodies 6 as the exhaust duct 31. Each layer crossing the dry body in the left-right direction is the last layer if the front of the dry body 6 is the hot air layer 7 and the last layer if the front of the dry body 6 is the exhaust air layer 9. The layer is configured to be the exhaust layer 9.

さらに、乾燥部３の前面の側板と、それぞれの乾燥体６と排風室１１の間には熱風通路２７が備えられていて、乾燥装置本体の略中央に備えた燃焼装置１５と外気の吸引で発生する乾燥風を排風室１１に流通しないように規制板３５によって区切られていて、乾燥風を左右の熱風室１０に均等に流通させるようになっている。   Further, a hot air passage 27 is provided between the side plate on the front surface of the drying unit 3 and between the respective drying bodies 6 and the exhaust air chamber 11, and the combustion device 15 provided in the approximate center of the drying device main body and the suction of outside air. Is separated by a regulating plate 35 so as not to circulate the dry air generated in the exhaust air chamber 11 so that the dry air is evenly distributed to the left and right hot air chambers 10.

乾燥装置本体の略中央に配置された送風機１６の吸引作用によって、燃焼装置１５で発生した乾燥風は、乾燥装置前面側板と規制板３５の間の熱風通路２７内から左右の熱風室１０に達し、左右の乾燥体６に対照設けられた乾燥層７から乾燥層８を通過し、排風層９から排風室１１に達し、送風機１６から機外に排出される。排風室１１と繋がる排風層９は左右対称に設けられているので、乾燥体６を通過する乾燥風が均一となり、また排風室１１内も乱流が発生しないので、均一に吸引し塵埃等が排風室１１内に堆積する割合が少なくなる。   Due to the suction action of the blower 16 disposed substantially at the center of the drying apparatus main body, the drying air generated in the combustion apparatus 15 reaches the left and right hot air chambers 10 from within the hot air passage 27 between the drying apparatus front side plate and the regulation plate 35. The left and right dry bodies 6 pass through the dry layer 7 provided as a control, pass through the dry layer 8, reach the exhaust chamber 11 from the exhaust layer 9, and are discharged from the blower 16 to the outside. Since the exhaust air layer 9 connected to the exhaust air chamber 11 is provided symmetrically, the dry air passing through the drying body 6 becomes uniform, and no turbulent flow is generated in the exhaust air chamber 11, so that the air is sucked uniformly. The rate at which dust or the like accumulates in the exhaust chamber 11 is reduced.

以上のように、乾燥部３を乾燥体６を二つ使用してその中央から送風機によって吸引を行うことで、より均一な乾燥を行うことが出来るほか、排風室内での乱流をなくすことが出来るので堆積する塵埃をより少なくすることが出来る効果が期待できる。また、乾燥装置自体が大型化する必要があっても、新たな強度を増した乾燥部を開発しなくても、従来の乾燥部を乾燥体として複数使用することで強度的にも、コスト的にも、均一な乾燥能力でも優れた乾燥部を提供することができる。   As described above, the drying unit 3 uses two drying bodies 6 and sucks them from the center with a blower, so that more uniform drying can be performed and turbulence in the exhaust chamber is eliminated. Therefore, the effect that the accumulated dust can be reduced can be expected. Moreover, even if it is necessary to increase the size of the drying device itself, it is possible to increase the strength and cost by using a plurality of conventional drying units as drying bodies, without developing a drying unit with increased strength. In addition, an excellent drying section can be provided even with a uniform drying capacity.
