【発明の属する技術分野】
この発明は、穀粒乾燥機の乾燥タンクに関し、穀粒乾燥時の収容穀粒の流下を円滑に行わせると共に、乾燥タンク組立時の組立容易化を図る。
【0002】
【発明が解決しようとする課題】
上部の乾燥タンクに収容した穀粒を下部の通風乾燥室へ流下させながら乾燥する穀粒乾燥機にあっては、この乾燥タンク内部に取付ける穀粒流下案内用の傾斜板の組付作業が面倒で手数を要する。この発明は、この傾斜板の組付を一人でも容易にできるようにしたものである。
【0003】
【課題を解決するための手段】
この発明は、収容穀粒を下部の通風乾燥室1へ流下案内する傾斜板2を有した乾燥タンク3の四隅部4に前後側壁5及び左右側壁6に対して鈍角の隅切側壁7をこの前後側壁5と一体形成し、この隅切側壁7部で該傾斜板2の前後端部8を支持可能とすることを特徴とする穀粒乾燥機の乾燥タンクの構成とする。
【0004】
【発明の効果】
乾燥タンク3の組立作業時には、前後側壁5間に傾斜板2を介挿させることにより、この傾斜板2が外側へ傾斜すると、前後端部8が前後側壁5と一体の隅切側壁7に支持されて、外側方へ転倒、落下を阻止される。このような傾斜板2の支持の状態で前後端部8を前後壁5乃至隅切側壁7に対してボルト締め等によって連結固定することができる。このため、傾斜板2を組付けるときの、特別の支持構成や操作を要することなく、一人作業でも簡単、容易な組付作業を行うことができる。
【0005】
隅切側壁7は、乾燥タンク3の四隅部4にあって、前後側壁5及び、左右側壁6に対して鈍角に形成されるものであるから、収容穀粒の流下時の抵抗力を小さくして、円滑な流下を行わせるが、この隅切側壁7は、前後側壁5と一体構成として組立てられるものであるから、構成も簡単である。
【0006】
【実施例】
穀粒乾燥機は、穀粒を循環移送しながら通風乾燥室1で熱風を当てて乾燥する循環熱風乾燥形態である。上部に乾燥タンク3を配置して、揚穀機9によって供給される穀粒を収容し、下部には前後側壁5間に亘る中央部の山形傾斜板10とこの左右両側部の傾斜板2とを配置して、下方の通風乾燥室1へ穀粒を流下させる。この乾燥タンク3は、上部タンク11と、該各傾斜板2,10を有する下部タンク12とから組立てられる。
【0007】
この乾燥タンク3を搭載する下部の基部フレーム13は、左右両側に乾燥網14を有する通風乾燥室1を左右二連に配置し、これら左右の通風乾燥室1間にはバーナ15による熱風を送込む熱風室16を形成し、各通風乾燥室1の外側には、各通風乾燥室1を通風された排風を案内する排風室17を形成する。18は各排風室17外側の外壁、19は底部の八樋板で、この八樋板19の下端部を前後方向に沿う移送螺旋20が設けられ、各通風乾燥室1から繰出羽根21の回転によって繰出される乾燥穀粒を受けて移送し、終端部から前記揚穀機9へ送り出して揚穀搬送させる。
【0008】
前記乾燥タンク3は、前後側壁5と左右側壁6と四隅部4の隅切側壁7とによって方形状の箱形に構成し、これら各側壁5,6,7の接合部は外側に合せリブ22を有してボルト23で締付固定できる組付形態である。このうち隅切側壁7は、前後側壁5の左右両側端に取付けるが、一枚板によって一体形成するもよい。
【0009】
下部タンク12内に配置する山形傾斜板10及び傾斜板2は、下端縁を前記乾燥網14の上端縁に接続させた状態にして、前後端部8に形成の合せリブ24を前後側壁5乃至隅切側壁7の内面に重合させてボルト25で締付固定する。外側の傾斜板2の前後端部8は、上部が前記隅切側壁7に沿って重合するように斜めに形成される。
【0010】
このような穀粒乾燥機の組立は、前記基部フレーム13を組立てた後ちに乾燥タンク3の下部タンク12を組付けるが、このとき山形傾斜板10を中央部の熱風室16上に覆うようにして載せて取付けて、前後側壁5を基部フレーム13の前後側壁部上に取付ける。この山形傾斜板10の合せリブ24と前後側壁5との間をボルト25で締付固定する。
【0011】
続いて、外側の傾斜板2を前後側壁5間に介挿して、下端縁を下側の乾燥網14上に支持させて、上端縁を外側方へ位置させて傾斜させる。このとき傾斜板2の前後端部8は前後側壁5と一体の隅切側壁7部に支持される。この状態でこれら傾斜板2の前後端部8に形成される合せリブ24と前後側壁5及び隅切側壁7との重合部をボルト25締めで固定する。
【0012】
このようにして各傾斜板2,10の組付けが終ると、外側の左右側壁6を前後側壁5間に亘って組付ける。この下部タンク12の組立が終ると上部タンク11の組立を行う。
なお、前記基部フレーム13の外壁18は、外側方へ回動させて、八樋板19上から外方へ張出しうる構成とし、この外壁18の開かれた開放部から移送螺旋20への穀粒供給を行いうる構成としている。又、前記熱風室16の前側壁側にはバーナ15を連通させているが、このバーナ15の横側には排風室17と連通する吸引排風機を設けると共に、前記移送螺旋20樋26と連通する揚穀機9を配置している。
【0013】
乾燥タンク3に収容された穀粒は、繰出羽根21の回転によって通風乾燥室1内を流下される。ここで熱風室16から排風室17へ横断するように流れる熱風を受けて乾燥される。この繰出羽根21によって繰出される穀粒は、移送螺旋20樋26を移送され、揚穀機を経て乾燥タンク3へ還元される。
この上部タンク11内から下部タンク12内を流下される穀粒は、四隅部4では隅切側壁7を案内されるため、穀粒の流下は円滑に行われ、穀粒の乾燥むらを生じ難い。下部タンク12では山形傾斜板10と外側の傾斜板2とに案内されて狭幅の通風乾燥室1内へ案内される。
【0014】
図6〜図9において、上例と異なる点は、前記熱風室16の下側に設けられる棚板27の構成に関し、この棚板27の取付構成を簡単化し、棚板27上の掃除を行い易くする。基部フレーム13の後側には、前記左右の排風室17と吸引排風機28との間を連通する排風ボックス29を設け、この下側の後側壁30に棚板27のシャッタ31を出入れ自在のシャッタ口32を設け、外側から蓋45で閉鎖しうる構成としている。
【0015】
棚板27は、左右両側端に前記繰出羽根21の回転周面上に接近する案内板33を有し、後半部分には掃除口34を開設して、この掃除口34の前縁、後縁部には横方向に亘るスクレパー35,36が形成される。この棚板27の下側には、シャッタ31の左右両側部を前後摺動自在にして受けるレール37を有し、このレール37で案内されるシャッタ31の上側面にスクレパー35,36が接近する。
【0016】
又、シャッタ31の下側には前後方向操作ロッド38が設けられる。この操作ロッド38の後端のフック39をシャッタ31後端の係止部40へ係合させることができ、この係止部40へフック39を係合することによって前端部のハンドル41を前側壁42から前方へ引き抜いて、シャッタ31を前後方向Aへ移動させて、スクレパー35,36による堆積塵埃の掃除を行わせることができる。
【0017】
前記棚板27上面の堆積塵埃を掃除するときは、前記前側壁42のバーナ15ケース43を前側へ回動して、熱風室16の前面口44を開いて、この前面口44からスクレパー等の掃除具を差込んで掃除する。
図10,図11において、上例と異なる点は、前記穀粒乾燥機の乾燥運転を行うコントローラにおいて、電源をONすることによって通風乾燥が行われる状態(通風乾燥モード)に設定し、穀粒の張込量を設定して、乾燥スイッチをONすることにより、自動的に通風運転が行われるように構成したものである。
【0018】
コントロールボックス46には、乾燥タンク3への穀粒の張込を行う張込スイッチ47、バーナ15や吸引排風機28、繰出羽根21の各部を駆動して乾燥を開始する乾燥スイッチ48、乾燥穀粒を機外へ取出す排出スイッチ49、乾燥作業を停止する停止スイッチ50等を配置する。又、これら各スイッチの下方には、乾燥穀粒の種類に応じた乾燥速度を設定する乾燥設定スイッチ51と、その設定表示ランプ52、乾燥目標の設定水分値を設定する水分設定スイッチ53と、その設定表示ランプ54、及び、乾燥タンク3に対する穀粒の張込量を設定する張込量設定スイッチ55と、その設定表示ランプ56等を配置している。
【0019】
これら各設定スイッチ51,53,55等は一回押す毎に設定表示のLED表示ランプ52,54,56は左側から右側へ順次移動し、右端を過ぎると左端へ移るようになっている。又、張込量表示ランプ56では、右端に通風乾燥ランプ57があって、外気を通風乾燥室1に送風して乾燥する通風乾燥が行われることを(通風乾燥モード)表示するようになっている。
【0020】
この通風乾燥ランプ57は、前記電源スイッチをONすることによって転倒され、乾燥スイッチ48をONすることによって通風乾燥が開始される。
なお、穀粒が乾燥タンク3に張込まれているときは、張込スイッチ47のONによって通風乾燥を開始させるようにしてもよい。又、張込量設定後に張込スイッチ47をONするか、乾燥スイッチ48をONするか、排出スイッチ49をONするか、又は、停止スイッチ50をONすることによって通風乾燥を開始するように構成するもよい。
【0021】
ただし、乾燥作業の形態としては、穀粒張込後に通風乾燥運転を行い、その後に熱風乾燥を行うことが多く、安全な乾燥を行うことができるからである。

BACKGROUND OF THE INVENTION
The present invention relates to a drying tank of a grain dryer, which facilitates the flow of stored grains during grain drying and facilitates assembly during assembly of the drying tank.
[0002]
[Problems to be solved by the invention]
For a grain dryer that dries while allowing the grains contained in the upper drying tank to flow down to the lower ventilation drying chamber, the work of assembling the inclined plate for the grain flow guide installed inside this drying tank is troublesome. It takes time. In the present invention, even one person can easily assemble the inclined plate.
[0003]
[Means for Solving the Problems]
In the present invention, a corner-cut side wall 7 having an obtuse angle with respect to the front and rear side walls 5 and the left and right side walls 6 is provided at the four corners 4 of the drying tank 3 having inclined plates 2 for guiding the stored grains down to the ventilation drying chamber 1. It is formed integrally with the front and rear side walls 5, and the configuration of the drying tank of the grain dryer is characterized in that the front and rear end portions 8 of the inclined plate 2 can be supported by the seven corner cut side walls.
[0004]
【The invention's effect】
When the drying tank 3 is assembled, the inclined plate 2 is interposed between the front and rear side walls 5 so that when the inclined plate 2 is inclined outward, the front and rear end portions 8 are supported by the corner side walls 7 integrated with the front and rear side walls 5. Then, it falls outside and is prevented from falling. The front and rear end portions 8 can be connected and fixed to the front and rear walls 5 to the corner-cut side walls 7 by bolting or the like while the inclined plate 2 is supported. For this reason, when assembling the inclined plate 2, it is possible to perform a simple and easy assembling work by one person without requiring a special support configuration or operation.
[0005]
Since the corner-cut side wall 7 is formed at an obtuse angle with respect to the front and rear side walls 5 and the left and right side walls 6 at the four corners 4 of the drying tank 3, the resistance force when the stored grains flow down is reduced. The corner-cut side wall 7 is assembled as a unitary structure with the front and rear side walls 5, so that the configuration is simple.
[0006]
【Example】
A grain dryer is a circulation hot-air drying form which dries with hot air in the ventilation drying chamber 1 while circulating and transporting grains. The drying tank 3 is arranged at the upper part to accommodate the grains supplied by the masher 9, and at the lower part, the central angled plate 10 extending between the front and rear side walls 5 and the inclined plates 2 at the left and right side parts And the grain is allowed to flow down to the ventilation drying chamber 1 below. The drying tank 3 is assembled from an upper tank 11 and a lower tank 12 having the inclined plates 2 and 10.
[0007]
The lower base frame 13 on which the drying tank 3 is mounted has a ventilation drying chamber 1 having drying nets 14 on both the left and right sides arranged in two left and right sides, and hot air from a burner 15 is sent between the left and right ventilation drying chambers 1. Hot air chambers 16 are formed, and on the outside of each ventilation drying chamber 1, an exhaust chamber 17 that guides the exhausted air that has been passed through each ventilation drying chamber 1 is formed. Reference numeral 18 denotes an outer wall on the outside of each exhaust chamber 17, and 19 is a bottom octagon plate. A transfer spiral 20 is provided along the front and rear direction of the lower end portion of the octagon plate 19. The dried grain fed by rotation is received and transferred, and sent from the terminal portion to the masher 9 to be conveyed.
[0008]
The drying tank 3 is formed in a rectangular box shape by the front and rear side walls 5, the left and right side walls 6, and the corner-cut side walls 7 of the four corners 4. This is an assembly form that can be fastened and fixed with bolts 23. Of these, the corner-cut side walls 7 are attached to the left and right side ends of the front and rear side walls 5, but may be integrally formed by a single plate.
[0009]
The angled slope plate 10 and the sloped plate 2 disposed in the lower tank 12 have bottom edges connected to the top edge of the drying net 14, and mating ribs 24 formed on the front and rear end portions 8 are arranged on the front and rear side walls 5 to 5. It is superposed on the inner surface of the corner-cut side wall 7 and fastened with bolts 25. The front and rear end portions 8 of the outer inclined plate 2 are formed obliquely so that the upper portion overlaps along the corner-cut side wall 7.
[0010]
In such a grain dryer assembly, the lower tank 12 of the drying tank 3 is assembled after the base frame 13 is assembled. At this time, the mountain-shaped inclined plate 10 is covered on the hot air chamber 16 in the center. The front and rear side walls 5 are mounted on the front and rear side wall portions of the base frame 13. The fitting rib 24 and the front and rear side walls 5 of the angled inclined plate 10 are fastened and fixed with bolts 25.
[0011]
Subsequently, the outer inclined plate 2 is inserted between the front and rear side walls 5, the lower end edge is supported on the lower drying net 14, and the upper end edge is positioned outward to be inclined. At this time, the front and rear end portions 8 of the inclined plate 2 are supported by the corner cutting side wall 7 integral with the front and rear side walls 5. In this state, the overlapping portions of the alignment ribs 24 formed on the front and rear end portions 8 of these inclined plates 2 with the front and rear side walls 5 and the corner-cut side walls 7 are fixed with bolts 25.
[0012]
When the assembly of the inclined plates 2 and 10 is completed in this way, the outer left and right side walls 6 are assembled across the front and rear side walls 5. When the assembly of the lower tank 12 is finished, the upper tank 11 is assembled.
The outer wall 18 of the base frame 13 is configured to be able to project outward from the top of the yam board 19 by rotating outwardly, and the grain from the open part of the outer wall 18 to the transfer spiral 20 is used. It is configured to be able to supply. A burner 15 communicates with the front side wall of the hot air chamber 16. A suction exhaust device communicating with the exhaust air chamber 17 is provided on the side of the burner 15, and the transfer spiral 20 26 is connected to the hot air chamber 16. A communicating cerealing machine 9 is arranged.
[0013]
The grains accommodated in the drying tank 3 are caused to flow down in the ventilation drying chamber 1 by the rotation of the feeding blade 21. Here, the hot air flowing from the hot air chamber 16 to the exhaust air chamber 17 is received and dried. The grain fed by the feeding blade 21 is transferred through the transfer spiral 20 26 and is returned to the drying tank 3 through the cerealing machine.
Since the grain flowing down from the upper tank 11 into the lower tank 12 is guided along the corner-cut side walls 7 at the four corners 4, the grain flows smoothly and is less likely to cause uneven drying of the grains. . In the lower tank 12, it is guided by the angled inclined plate 10 and the outer inclined plate 2 and is guided into the narrow ventilation drying chamber 1.
[0014]
6 to 9, the difference from the above example is related to the configuration of the shelf plate 27 provided on the lower side of the hot air chamber 16, and the mounting configuration of the shelf plate 27 is simplified, and the shelf plate 27 is cleaned. Make it easier. On the rear side of the base frame 13, there is provided an exhaust box 29 for communicating between the left and right exhaust chambers 17 and the suction exhauster 28, and the shutter 31 of the shelf plate 27 is provided on the lower rear side wall 30. A shutter port 32 that can be freely inserted is provided and can be closed with a lid 45 from the outside.
[0015]
The shelf plate 27 has guide plates 33 that approach the rotational peripheral surface of the feeding blade 21 at both left and right ends, and a cleaning port 34 is formed in the rear half part, and the front and rear edges of the cleaning port 34 are provided. Scrapers 35 and 36 extending in the lateral direction are formed in the part. Below the shelf 27, there is a rail 37 that receives the left and right sides of the shutter 31 so as to be slidable back and forth. The scrapers 35 and 36 approach the upper side surface of the shutter 31 guided by the rail 37. .
[0016]
A front / rear direction operation rod 38 is provided below the shutter 31. A hook 39 at the rear end of the operating rod 38 can be engaged with a locking portion 40 at the rear end of the shutter 31, and by engaging the hook 39 with the locking portion 40, the handle 41 at the front end can be engaged with the front side wall. By pulling forward from 42 and moving the shutter 31 in the front-rear direction A, the accumulated dust can be cleaned by the scrapers 35 and 36.
[0017]
When cleaning the accumulated dust on the upper surface of the shelf 27, the burner 15 case 43 of the front side wall 42 is rotated to the front side to open the front opening 44 of the hot air chamber 16, and a scraper or the like is opened from the front opening 44. Insert a cleaning tool and clean.
10 and 11, the difference from the above example is that the controller for performing the drying operation of the grain dryer is set to a state where ventilation drying is performed by turning on the power (ventilation drying mode), and the grain Is set so that the ventilation operation is automatically performed when the drying switch is turned on.
[0018]
The control box 46 includes a tension switch 47 for tensioning the grain into the drying tank 3, a drying switch 48 for driving the burner 15, the suction exhaust fan 28, and the feeding blade 21 to start drying, A discharge switch 49 for taking out the grains and a stop switch 50 for stopping the drying operation are arranged. Also, below these switches, a drying setting switch 51 for setting a drying speed according to the type of dried grain, its setting display lamp 52, a moisture setting switch 53 for setting a drying target moisture value, The setting display lamp 54, the tension amount setting switch 55 for setting the grain tension amount to the drying tank 3, the setting display lamp 56, and the like are arranged.
[0019]
Each time these setting switches 51, 53, 55, etc. are pressed once, the setting display LED display lamps 52, 54, 56 are sequentially moved from the left side to the right side, and are moved to the left end after passing the right end. Further, the tension amount display lamp 56 has a ventilation drying lamp 57 at the right end, and displays that ventilation drying is performed by blowing air to the ventilation drying chamber 1 and drying (ventilation drying mode). Yes.
[0020]
The ventilation drying lamp 57 is overturned by turning on the power switch, and ventilation drying is started by turning on the drying switch 48.
When the grain is stretched in the drying tank 3, ventilation drying may be started by turning on the tension switch 47. Further, after the tension amount setting, the ventilation switch 47 is turned on, the drying switch 48 is turned on, the discharge switch 49 is turned on, or the stop switch 50 is turned on to start ventilation drying. You may do it.
[0021]
However, as a form of the drying operation, it is because a ventilation drying operation is performed after the grain is put, and then hot air drying is often performed, so that safe drying can be performed.
