Description

【0001】
【発明の属する技術分野】
本発明は、脱穀部で処理された穀粒などを揚穀筒により揚上して穀粒タンク内に投入貯留する穀粒タンク内の穀粒満量検知装置に関する。
【0002】
【従来の技術】
従来、揚穀筒によって穀粒を揚上し穀粒タンク内に投入貯留する場合に、投入する穀粒が穀粒タンク内に満量になったことを知るための穀粒センサ−なるものが設けられ、その穀粒センサ−をブザ−等に接続して穀粒センサ−が満量を検知するとブザ−等を鳴らして作業者に知らせるようにしている。
【0003】
【発明が解決しようとする課題】
しかし、揚穀筒内から揚上された穀粒が穀粒タンク内に投入されるとき、揚穀筒内の跳ね出し板により跳ね出されるため吐出風が発生し、その吐出風によって穀粒タンク内の風圧が上昇し、この風圧の上昇により穀粒センサ−をON作動させるようになって誤作動を起こしてしまう欠点がある。
【0004】
【課題を解決するための手段】
本発明によれば、穀粒タンク内に揚穀筒により揚上して投入貯留する穀粒が満量になったことを検知する穀粒センサ−を設けたもので、穀粒タンクの側壁上部に排風口を開口し、該排風口に排風ダクトを連通連結して穀粒タンク内を外部と連通した穀粒タンク内の穀粒満量検知装置において、前記排風口を、穀粒センサ−の下側近傍部に開口し、その排風口に連通連結する排風ダクトを上向きにしたので、揚穀筒内の上端部から跳ね出し板により穀粒タンク内に投入されるとき、発生する吐出風は側壁上部に開口する排風口から排風ダクトを通して外部に逃げるから、穀粒タンク内の風圧が弱くなり穀粒センサ−は吐出風の影響を受けることがなく誤作動を起こすことがない。
【0005】
そして、穀粒センサ−を排風口の近傍部に設けたことにより、揚穀筒内からの吐出風による穀粒センサ−周辺の風圧は一段と弱体化して穀粒センサ−の作動が正確なものになる。
【0006】
また、排風口に連通連結する排風ダクトを上向きにしたことにより、穀粒タンク内に投入される穀粒の排風口から外部への飛散が排風ダクトによって防止される。
【0007】
更に、穀粒センサ−の下がわに排風口を開口したことにより、吐出風はこの穀粒センサ−の下がわの排風口から外部に逃げるようになって、穀粒センサ−の前面を通過するので風圧の影響を全く受けなくなる。その上、排風口が投入される穀粒で塞がって穀粒センサ−が風圧によって作動しても、排風口と穀粒センサ−は近接位置にあるから満量の検知には一向に差し支えない。
【0008】
【発明の実施の形態】
【実施例】
以下、本発明による穀粒満量検知装置に関し実施例図を参照して詳述すると、図1はコンバインの左側面図を示し、図2は同コンバインの平面図であって、先ずこのコンバインの概要について記載しておく。
【0009】
このコンバインはクロ−ラ式の走行装置(6)上の左側に刈取部(B)からの刈取穀稈を脱穀処理する脱穀部(A)を搭載し、右側には脱穀部(A)で処理された穀粒を貯留する穀粒タンク(1)を載設して脱穀部(A)に並設し、穀粒タンク(1)の前側に操縦部を内装するキャビン(7)が設けられ、脱穀部(A)の前方からキャビン(7)の前側にかけて刈取部(B)が、脱穀部(A)の後側には排藁カッタ−(C)がそれぞれ連設されている。
【0010】
即ち、刈取部(B)で刈取られた穀稈は後方に搬送されて脱穀部(A)で脱穀処理され、処理済の藁稈は排藁カッタ−(C)によって細断されるとともに、穀粒は脱穀部(A)から揚穀筒(2)により揚上され跳ね出し板によって跳ね出され穀粒タンク(1)内に投入貯留される。そして、この貯留された穀粒は排出オ−ガ(8)により適宜機外に取出されるようになっている。
【0011】
また、前記の穀粒タンク(1)は仮想線(イ)で示すように右外側方に回動可能にして刈取作業の終了時などにおける点検整備作業を容易にしている。
【0012】
本発明による穀粒満量検知装置は、前述のように、揚穀筒(2)から穀粒タンク(1)内に投入貯留されるとき、その貯留される穀粒が満量になったことを知るためのものであって、(3)は穀粒タンク(1)の側壁を示し、(4)はその側壁(3)の上部に開口した排風口、(5)は下端部を排風口(4)に連通連結して上向きにし側壁(3)にそって設けた排風ダクトである。
【0013】
そして、前記排風口(4)を開口する側壁(3)部分は図7と図8に記載のようになっている。即ち、(4)が排風口で、その上側に後述する穀粒センサ−(S)を穀粒タンク(1)内にのぞませるための開口(9)が設けられている。
【0014】
図3と図4に示したものは前記排風ダクト(5)を形成する上下方向に長手の内側板(5a)で、この内側板(5a)の下部に前記排風口(4)に合致する連通口(10)を開設し、中央部には穀粒センサ−(S)を取付け、その穀粒センサ−(S)は矢印(ロ)の方向からの圧力によってへこみ、接点(S1)の接触によりスイッチがONしてブザ−が鳴るようになっている。また、(11)は穀粒センサ−(S)内部と外部を通じる通気口である。
【0015】
また、図5と図6は排風ダクト(5)を形成する外側板(5b)であって、薄鉄板を同各図のようにプレス成形して上下方向の縦通路部(12)と、その縦通路部(12)の上端部から横向きの横通路部(13)を形設している。
【0016】
前記のように形成した外側板(5b)を内側板(5a)に合わせ、内側板(5a)に取付けた穀粒センサ−(S)を側壁(3)に設けた開口(9)を通して穀粒タンク(1)内にのぞませるとともに、連通口(10)を排風口(4)に合致させ、数本の取付ボルト(14)によって側壁(3)に締め付けると、図9と図10に示すように連通口(10)から縦通路部(12)内を上昇し横通路部(13)内を通って外部に排風する排風ダクト(5)が構成されるのであって、前記穀粒センサ−(S)は排風口(4)の近傍部にあって、しかも、その穀粒センサ−(S)の下がわに排風口(4)が位置するのである。
【0017】
したがって、揚穀筒(2)から穀粒が穀粒タンク(1)内に投入貯留されるとき発生する吐出風は穀粒センサ−(S)の前面を図10に矢印(ハ)で示すように通過し排風口(4)から連通口(10)を経て排風ダクト(5)内を(ニ)のように上昇したのち横方向に向きを変えて外部に排出されるようになり、穀粒タンク(1)内の風圧は弱まり、特に、穀粒センサ−(S)の周辺の風圧は弱体化して穀粒センサ−(S)は誤作動を起こさず、満量になった穀粒によってのみ作動して作業者にそのことを知らせるのである。
【0018】
【発明の効果】
本発明は、以上説明したような形態で実施され、次に記載するような効果を奏する。
【0019】
即ち、穀粒タンク内に揚穀筒により揚上して投入貯留する穀粒が満量になったことを検知する穀粒センサ−を設けたもので、穀粒タンクの側壁上部に排風口を開口し、該排風口に排風ダクトを連通連結して穀粒タンク内を外部と連通した穀粒タンク内の穀粒満量検知装置において、前記排風口を、穀粒センサ−の下側近傍部に開口し、その排風口に連通連結する排風ダクトを上向きにしたので、揚穀筒内の上端部から跳ね出し板により穀粒タンク内に投入されるとき、発生する吐出風は側壁上部に開口する排風口から排風ダクトを通して外部に逃げるから、穀粒タンク内の風圧が弱くなり穀粒センサ−は吐出風の影響を受けることがなく誤作動を起こすことがないようになって穀粒センサ−の信頼性を高めることができる。
【0020】
そして、穀粒センサ−を排風口の近傍部に設けたことにより、揚穀筒内からの吐出風による穀粒センサ−周辺の風圧は一段と弱体化して穀粒センサ−の作動が正確なものになり、満量検知が確実になる。
【0021】
また、排風口に連通連結する排風ダクトを上向きにしたことにより、穀粒タンク内に投入される穀粒の排風口から外部への飛散が排風ダクトによって防止され穀粒の損失が生じない。
【0022】
更に、穀粒センサ−の下がわに排風口を開口したことにより、吐出風はこの穀粒センサ−の下がわの排風口から外部に逃げるようになって、穀粒センサ−の前面を通過するので風圧の影響を全く受けなくなる。その上、排風口が投入される穀粒で塞がって穀粒センサ−が風圧によって作動しても、排風口と穀粒センサ−は近接位置にあるから満量の検知には一向に差し支えないのである。
