Description

【0001】
【発明の属する技術分野】
この発明は、コンバイン等の作業車において、大豆、小豆、米、麦、蕎麦等の穀粒を一時的に貯留する穀粒貯留装置に関するものである。
【0002】
【従来の技術】
従来,例えばコンバインには穀粒貯留タンクを装備して所定量の穀粒を一時貯留できる構成として、畦畔際に待機する運搬車には、スクリュー螺旋を内装する排出筒によって穀粒排出する構成とするが、長い排出筒を経て穀粒を排出するから、排出時間が長くなる。
【0003】
このため、特開平7−203757号公報に開示されるように、穀粒貯留タンクを走行機体の外側上方に持ち上げて穀粒排出口から貯留穀粒を自然流下させて取出す構成がある。
【0004】
【発明が解決しようとする課題】
ところが、上記の穀粒貯留タンクを機体の外側上方に持ち上げる構成では、待機する運搬車に排出すべくタンクを高く上昇回動させる必要があるため、上昇リンク構成にはかなりの強度を必要とし穀粒貯留タンク容量に制限がある。また、複雑な昇降リンク構成となる欠点がある。
【0005】
この発明は、穀粒貯留タンク自体の容量を確保しながら圃場内での穀粒排出を簡単化しコスト低減を図りつつ穀粒排出時間の短縮を図り、併せて穀粒排出に際しての安全を図るものである。
【0006】
【課題を解決するための手段】
この発明は上記課題に鑑み、以下のように構成した。即ち、請求項1の発明では、移動車体の左右右側に配置され順次供給される穀粒を貯留する穀粒貯留タンクタンクシリンダ機構13,13の作動により支柱10,10…に沿わせて上下昇降自在に設けると共に、該タンク上昇位置で排出口部から適宜に穀粒を機外排出可能に設ける穀粒貯留装置において、左右走行クローラ2L,2Rを備える走行フレーム3L,3Rに左右ローリングシリンダ4L,4Rを介して移動車体5を設け、前記穀粒貯留タンク8を昇降する昇降スイッチ25、穀粒貯留タンク8内の貯留穀粒量を検知する穀粒量検知センサ26、車体の左右傾斜状態を検出する車体傾斜検知センサ27を設け、前記昇降スイッチ25のオン操作によりタンク上昇側指令信号が入力されると、車体傾斜検知センサ27と穀粒量検知センサ26が読み込まれ、穀粒貯留タンク8の穀粒量が満杯状態(Wmax)であると、タンクシリンダ機構13,13にタンク上昇出力が出されると共に左・右ローリングシリンダ4L,4Rの伸縮によって車体5を左側下方となるよう傾斜させ、穀粒量が所定量以下(<W1)になると車体5を水平姿勢に戻す制御部17を設けたことを特徴とする作業車の穀粒貯留装置とする。
【0007】
このように構成すると、穀粒量が満杯状態(Wmax)でタンク上昇するときは、車体右側にある穀粒貯留タンク8による荷重が左傾斜になった車体に作用する。そして、穀粒排出を開始し、所定量以下(<W1)になると、車体5を水平姿勢に戻す。
【0008】
請求項2では、穀粒量が減少して前記所定量よりも少ない第2の所定量以下(<W2)となると、左・右ローリングシリンダ4L,4Rの伸縮によって車体5を右側下方となるよう傾斜させる制御部17とした。
【0009】
これによって、さらに穀粒排出が進んでタンク8に残る穀粒量が少なくなると、車体は右下がり状態となる。
【0010】
【0011】
【0012】
【0013】
【0014】
【発明の効果】
請求項1に記載の発明によると、穀粒量が満杯状態(Wmax)でタンク上昇するときは、車体右側にある穀粒貯留タンク8による荷重が左傾斜になった車体5に作用するため転倒し難く安全である。
【0015】
請求項2に記載の発明によると、さらに穀粒排出が進んでタンク8に残る穀粒量が少なくなると、車体は右下がり状態となるため、タンク内穀粒の排出が円滑となる。
【0016】
【0017】
【発明の実施の形態】
以下、図に基づいて、この発明の実施の形態を説明する。図1は、コンバイン1の側面図を示すものであって、左右走行クローラ2L,2Rを備える走行フレーム3L,3Rに左右ローリングシリンダ4L,4Rを介して移動車体5を設け、この移動車体5の上方の一側(機体左側)に脱穀部6を搭載し、他側に操縦部7と穀粒貯留タンク8とを前後に設けている。
【0018】
上記移動車体5の前部には刈取部9を上下昇降回動可能に連結し、この刈取部9で刈り取られた大豆、小豆、蕎麦、麦、稲等の穀物は、図示しない搬送装置によって上記脱穀部6に案内され、ここで脱穀された後、上記穀粒貯留タンク8に回収される構成である。
【0019】
上記穀粒貯留タンク8は、上部の断面方形の貯留部8aと、これに接続し排出筒8cを備える樋状の排出部8bとからなり、移動車体5に立設する4本の支柱10,10…に摺動自在に嵌合する筒体11,11…に溶接等の手段によって連結され、もって穀粒貯留タンク8自体が支柱10,10…に沿って上下に摺動する昇降自在の構成である。
【0020】
上記筒体11,11…のうち前後側同士の一対が逆Vフレーム12,12によって連結され、各フレーム12,12の頂部と移動車体5との間に油圧によるタンクシリンダ機構13,13を設け、作動油の給排制御に伴い略垂直状態で伸縮作動し得て、穀粒貯留タンク8を上下昇降連動すべく構成している。
【0021】
前記穀粒貯留タンク8の下降位置では、脱穀部6における一番揚穀筒14の上部排出樋端と当該穀粒貯留タンク8に形成する導入孔(図示せず)とが一致して穀粒供給可能に設けられている。なお、穀粒貯留タンク8の上昇位置では、該導入孔を塞ぐ溢出防止板(図示せず)をバネ等の付勢手段で強制作動して非作用位置から溢出防止作用位置に動作させる構成としている。一方上記一番揚穀筒14の上部排出樋端には、この排出樋端を塞ぎ得る溢出防止弁(図示せず)を介在し、図外電動モータによって開閉しうる構成としている。
【0022】
また、機体側方に向けた穀粒貯留タンク8の排出筒8c先端には排出シャッタ15を設け、電動モータ16の正逆回転に連動して開閉する構成である。17は穀粒貯留タンク8の昇降制御及び移動車体の左右傾斜制御を行なう制御部で、タンクシリンダ機構13への作動油の給排を司る制御弁18の上昇用ソレノイド19、下降用ソレノイド20へ適宜信号出力するほか、前記左右ローリングシリンダ4L,4R伸出用ソレノイド21L,21R、同シリンダ短縮用ソレノイド22L,22R作動出力、警報ブザー23出力、前記電動モータ16への正逆回転を司る開閉スイッチ24の出力等がある。なお入力信号としては、昇降スイッチ25信号、穀粒貯留タンク8内貯留穀粒量検知センサ26、車体傾斜検知センサ27の各検知信号、機体の走行を司る変速操作レバー28(HSTレバー)の中立位置検知センサ29の検知信号、刈取部9の昇降位置を検知する超音波型高さ検出センサ30の高さ検知信号等がある。
【0023】
上記制御部15は、昇降スイッチ25操作でタンク上昇指令信号が出力されても、一定の条件下では上昇用ソレノイド17への通電が規制されタンクシリンダ12への作動油供給が規制される上昇規制手段を構成し、安全を確保している。即ち、前記変速操作レバー28が中立以外に操作され、コンバイン車体が移動状態あるいは移動可能な状態であるときは、制御部15は上昇用ソレノイド17への通電が行なわれない構成としている。なお、変速操作レバー28が中立位置に復帰するとこれを中立位置検知センサ30が検知し、上昇規制が解除され昇降スイッチ25の上昇側操作に伴い上昇用ソレノイド17へ通電される。
【0024】
また、移動車体5の傾斜状況を検知して上昇規制手段を作動する構成としており、その一例を図5に示している。昇降スイッチ25の上昇側操作に伴ない、車体傾斜検知センサ27によって左右の傾斜状態が検知され、左・右いずれかの方向への傾斜度が角度α以上であるときには、上昇規制手段が作動して警報ブザー23へ警報出力し、かつこの車体傾斜検知センサ27の検知信号の分析によって左右傾斜方向を判断した後、左・右ローリングシリンダ4L,4Rを伸・縮作動して車体を略水平状態に復帰させ、上記角度α範囲に達すると、上昇規制手段による出力を解除し、タンクシリンダ機構13を伸出すべくなす。なお、穀粒貯留タンク8が最上昇位置に達すると、タンクシリンダ機構13の作動を停止し、開閉スイッチ24を操作し排出シャッタ15を開出力する。このように、左右傾斜角が所定範囲以上のときは、上昇規制手段によってタンクシリンダ機構13の伸出出力が規制される構成である。
【0025】
更に、制御部17は、図6のフローチャートに示す制御を実行させるものである。即ち、車体5の左右傾斜角と貯留タンク8内の貯留量とによって、安全を確保しながらタンク内穀粒の排出時間の短縮あるいは残粒のない状態を具現すべく左右傾斜制御を実行するものである。昇降スイッチ25をオンし、上昇側指令信号が入力されると、車体傾斜検知センサ27,穀粒量検知センサ26が読み込まれる。先ず車体傾斜角度が予め設定したα以内にあるか否かが判定され、この所定範囲内にあり、穀粒量が満杯状態であると、タンクシリンダ機構13を伸出出力する。同時に左ローリングシリンダ4Lを伸出出力しながら右ローリングシリンダ4Rを短縮出力し、車体5をやや左側が下方となるよう傾斜させる(車体傾斜角度=−β、α>β)。よって穀粒量が満杯状態(Wmax)でタンク上昇するときには、車体右側にある穀粒貯留タンク8による荷重が左傾斜になった車体に作用するので転倒し難く安全である。穀粒排出を開始し、所定量以下(<W1)になると、車体を水平姿勢(傾斜角度=0)に戻すよう左右ローリングシリンダに作動油を給排して穀粒排出を継続する。さらに穀粒排出が進んでタンクに残る穀粒量が少なくなると(第2の所定量,<W2、ここでW2<W1)、車体傾斜角度が右下がり状態となるよう左右ローリングシリンダに作動油を給排する。このようにすると、タンク内穀粒の排出が円滑となる。穀粒量がなくなると、排出シャッタ15は閉じられる。昇降スイッチ25によって下降出力されると、タンクシリンダ機構13は短縮動し穀粒貯留タンク8は下降し所定の位置に復帰する。
【0026】
上例の作用について説明する。圃場においてコンバイン1を前進し植立穀稈を刈取部9で刈取ると、この刈取穀稈は順次脱穀部6に供給搬送され脱粒選別される。このうち、整粒は一番揚穀筒14を経由して下降停止位置にある穀粒貯留タンク8に供給される。
【0027】
穀粒貯留タンク8の貯留量が満杯Wmaxに達すると、穀粒量検知センサ26はこれを検知し、図外満杯ブザーに吹鳴出力する。補助作業員は穀粒タンク付き運搬車(例えば軽トラック)をコンバインの穀粒貯留タンク8側側面に接近して待機させる。コンバインに搭乗する作業員は昇降スイッチ25を上昇側にスイッチ操作すると、タンクシリンダ機構13は作動油給排によって伸び出し、穀粒貯留タンク8を支柱10,10…に沿って上昇させる。最上昇位置に達すると、タンクシリンダ機構13は伸び出しを停止し、タンク8も停止する。次いで開閉スイッチ24をもって開操作すると電動モータ16は正転して排出シャッタ15を開動する。これに伴い、タンク8内の穀粒は排出流下し下方にのぞむ運搬車の穀粒タンクに移される。
【0028】
穀粒貯留タンク8の貯留量Wが満杯のWmax状態からW1、W2を経て減少するに連れ、車体5の左右傾斜角を前記のようにやや左下右上傾斜、水平、左上右下傾斜となるよう、左右ローリングシリンダ4L、4Rを制御するものである。穀粒貯留タンク8の穀粒排出が完了すると、開閉スイッチ24を閉じ側操作するとともに、昇降スイッチ25を下降側に操作する。電動モータ16は逆転して開閉シャッタ15を閉じ側とし、穀粒貯留タンク8はタンクシリンダ機構13の短縮作動によって下降する。
【0029】
上記の穀粒貯留タンク8のタンクシリンダ機構には、制御部17からの上昇規制信号によって上昇規制手段が働き、昇降スイッチ25を上昇側に操作することによってもタンク上昇を行わせないものとなる。上昇規制手段は、(1)変速操作レバー28が中立位置にないとき、(2)車体が左右に所定角以上に傾斜しているとき、には規制出力してタンク上昇を行なわせない。したがって、タンク上昇によってコンバイン車体が不安定になり易いが、タンク上昇の際には極力車体の安定状態を選択して安全に作業できるよう構成されている。
【0030】
上昇規制手段による上昇規制の条件は、上記(1)(2)のほか、(3)刈取部9が作業姿勢にあるとき、例えば高さ検出センサ30の検出結果に基づき所定高さ以下にあるとき、あるいは図外脱穀クラッチがオンの状態で脱穀各部が駆動状態にあるとき、つまり作業状態にあると推定される条件のときには上昇規制手段によって穀粒貯留タンクの上昇を規制する。(4)コンバイン車体が移動しているか否かを検知し車体移動中には上昇規制する、(5)穀粒貯留タンク8自体が下降位置にあるか否かを検知し下降位置にないときは上昇規制する、等である。
【0031】
図7,8は穀粒貯留タンク8の上昇機構の別実施例を示すもので、車体5に立設せる垂直の下部支柱35に対して、上部支柱36を上側ほど車体5の外側方に張り出す傾斜状に設け、穀粒貯留タンク8の前後に設ける支持アーム37,37の左右端部にはローラ38,38…を配設してなり、これらローラ38,38…を上記上部支柱36に嵌合してある。上記支持アーム37,37の中間部をタンクシリンダ機構13,13に接続している。こうすることにより、穀粒排出位置のタンク8はコンバイン1の車体5横側方に張り出し状に上昇できる。このためコンバイン1に横付けする運搬車の後部を最接近させる際、タンク8の排出筒8cを車体5の横側方に張り出しできるからコンバイン1の横側との間に余裕を保って接近させ得、接触事故を防止できる。
【0032】
図9,10は穀粒貯留タンク8の上昇機構の更に別の実施例であり、車体5に対して垂直の下部支柱40と上部支柱41との間に上部支柱41を車体5横外側に変位させる中間支柱42を設け、下部支柱40と上部支柱41とを接続してなる。中間支柱42から上部支柱41に渡って穀粒貯留タンク8を移動しうるよう構成する。尚、タンク8を支柱に対して上下スライド自在に支持する構成は上記の例と同様である。この構成によっても、コンバイン1に横付けする運搬車の後部を最接近させる際、タンク8の排出筒8cを車体5の横側方に張り出しできるからコンバイン1の横側との間に余裕を保って接近させ得る。

BACKGROUND OF THE INVENTION
The present invention relates to a grain storage device that temporarily stores grains such as soybeans, red beans, rice, wheat, and buckwheat in a work vehicle such as a combine.
[0002]
[Prior art]
Conventionally, for example, a combine is equipped with a grain storage tank so that a predetermined amount of grain can be temporarily stored, and in a transport vehicle waiting on the shore, the grain is discharged by a discharge cylinder equipped with a screw spiral. However, since the grain is discharged through a long discharge tube, the discharge time becomes longer.
[0003]
For this reason, as disclosed in Japanese Patent Application Laid-Open No. 7-203757, there is a configuration in which the grain storage tank is lifted to the upper outside of the traveling machine body, and the stored grain is allowed to flow down naturally from the grain outlet.
[0004]
[Problems to be solved by the invention]
However, in the configuration in which the grain storage tank is lifted to the upper outside of the fuselage, it is necessary to raise and rotate the tank so as to be discharged to a waiting vehicle, so that the ascending link configuration requires considerable strength. There is a limit to the capacity of the grain storage tank. In addition, there is a drawback of a complicated lifting link configuration.
[0005]
This invention aims to shorten the grain discharge time while simplifying the grain discharge in the field while reducing the cost while securing the capacity of the grain storage tank itself, and also to ensure the safety at the time of the grain discharge. It is.
[0006]
[Means for Solving the Problems]
In view of the above problems, the present invention is configured as follows. That is, in the invention of claim 1, along the grain storage tank 8 for storing the grain which is arranged on both the right on the moving body 5 is sequentially supplied by the operation of the tank cylinder mechanism 13, 13 in the struts 10, 10 ... In a grain storage device that is provided so that it can be vertically moved up and down, and that the grain can be appropriately discharged from the discharge port at the tank 8 ascending position, on the traveling frames 3L and 3R including the left and right traveling crawlers 2L and 2R. A movable vehicle body 5 is provided via the left and right rolling cylinders 4L, 4R, a lift switch 25 that raises and lowers the grain storage tank 8, a grain amount detection sensor 26 that detects the amount of stored grain in the grain storage tank 8, a vehicle body The vehicle body inclination detection sensor 27 for detecting the left / right inclination state of the vehicle body is provided, and when a tank ascending side command signal is input by turning on the lift switch 25, the vehicle body inclination detection sensor 27 and the grain When the amount detection sensor 26 is read and the amount of the grain in the grain storage tank 8 is full (Wmax), the tank ascending output is output to the tank cylinder mechanisms 13 and 13 and the left and right rolling cylinders 4L and 4R are output. Kernel storage of a working vehicle, characterized in that a control unit 17 is provided to tilt the vehicle body 5 to the lower left side by expansion and contraction, and to return the vehicle body 5 to a horizontal posture when the grain amount becomes a predetermined amount or less (<W1). A device.
[0007]
If comprised in this way, when the amount of kernels rises in a full state (Wmax), the load by the grain storage tank 8 on the right side of the vehicle body acts on the vehicle body tilted to the left. Then, the grain discharge is started, and when the amount falls below a predetermined amount (<W1), the vehicle body 5 is returned to the horizontal posture.
[0008]
According to claim 2, when the grain amount decreases and becomes equal to or less than the second predetermined amount (<W2) smaller than the predetermined amount, the left and right rolling cylinders 4L and 4R extend and contract the vehicle body 5 to the lower right side. The control unit 17 is inclined.
[0009]
As a result, when the kernel discharge further proceeds and the amount of the kernel remaining in the tank 8 is reduced, the vehicle body is lowered to the right.
[0010]
[0011]
[0012]
[0013]
[0014]
【The invention's effect】
According to the first aspect of the present invention, when the amount of the grain rises in the full state (Wmax), the load by the grain storage tank 8 on the right side of the vehicle body acts on the vehicle body 5 that is inclined to the left, and thus falls. It is difficult and safe.
[0015]
According to the second aspect of the present invention, when the grain discharge further proceeds and the amount of the grain remaining in the tank 8 decreases, the vehicle body is lowered to the right, so that the grain in the tank is smoothly discharged.
[0016]
[0017]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a side view of a combine 1, and a moving vehicle body 5 is provided on left and right rolling cylinders 4L, 4R on traveling frames 3L, 3R including left and right traveling crawlers 2L, 2R. The threshing unit 6 is mounted on the upper side (the left side of the machine body), and the control unit 7 and the grain storage tank 8 are provided on the other side.
[0018]
A cutting portion 9 is connected to the front portion of the movable vehicle body 5 so as to be able to rotate up and down. Grains such as soybeans, red beans, buckwheat, oats, and rice harvested by the cutting portion 9 are transferred by a conveying device (not shown). After being threshed by the threshing unit 6, the threshing unit 6 collects the threshing portion 6.
[0019]
The grain storage tank 8 is composed of a storage section 8a having a rectangular cross section at the top and a bowl-shaped discharge section 8b connected to the storage section 8a and provided with a discharge cylinder 8c. Are connected to cylinders 11, 11, which are slidably fitted to 10... By means such as welding, so that the grain storage tank 8 itself slides up and down along the columns 10, 10. It is.
[0020]
A pair of the front and rear sides of the cylinders 11, 11... Are connected by inverted V frames 12, 12, and tank cylinder mechanisms 13, 13 are provided by hydraulic pressure between the tops of the frames 12, 12 and the moving vehicle body 5. With the hydraulic oil supply / discharge control, it can be expanded and contracted in a substantially vertical state, and the grain storage tank 8 is configured to be linked up and down.
[0021]
At the lowered position of the grain storage tank 8, the upper discharge end of the first lifting cylinder 14 in the threshing unit 6 and the introduction hole (not shown) formed in the grain storage tank 8 coincide with each other to supply the grain. It is provided as possible. Note that, in the raised position of the grain storage tank 8, an overflow prevention plate (not shown) that closes the introduction hole is forcibly operated by a biasing means such as a spring to move from the non-operation position to the overflow prevention action position. Yes. On the other hand, an overflow prevention valve (not shown) capable of closing the discharge hook end is interposed at the upper discharge hook end of the first cereal cylinder 14 and can be opened and closed by an electric motor (not shown).
[0022]
Further, a discharge shutter 15 is provided at the tip of the discharge cylinder 8 c of the grain storage tank 8 facing the machine body side, and is configured to open and close in conjunction with forward and reverse rotation of the electric motor 16. Reference numeral 17 denotes a control unit that performs the raising / lowering control of the grain storage tank 8 and the right / left tilt control of the moving vehicle body, to the raising solenoid 19 and the lowering solenoid 20 of the control valve 18 that controls supply / discharge of hydraulic oil to / from the tank cylinder mechanism 13. In addition to outputting appropriate signals, the left and right rolling cylinders 4L and 4R extending solenoids 21L and 21R, the cylinder shortening solenoids 22L and 22R actuating output, the alarm buzzer 23 output, and the open / close switch that controls forward and reverse rotation to the electric motor 16 There are 24 outputs. In addition, as an input signal, the up / down switch 25 signal, each detection signal of the stored grain amount detection sensor 26 in the grain storage tank 8 and the vehicle body tilt detection sensor 27, the neutral of the speed change operation lever 28 (HST lever) that controls the running of the machine body There are a detection signal of the position detection sensor 29, a height detection signal of the ultrasonic type height detection sensor 30 for detecting the raising / lowering position of the cutting unit 9, and the like.
[0023]
Even if the tank raising command signal is output by operating the raising / lowering switch 25, the control unit 15 regulates energization of the raising solenoid 17 under certain conditions and regulates the supply of hydraulic oil to the tank cylinder 12. The means are configured to ensure safety. That is, when the shift operation lever 28 is operated to a position other than neutral and the combine vehicle body is in a movable state or a movable state, the controller 15 is configured not to energize the lifting solenoid 17. When the shift operation lever 28 returns to the neutral position, the neutral position detection sensor 30 detects this, and the ascent restriction is released and the ascending solenoid 17 is energized when the ascending / descending switch 25 is operated.
[0024]
Moreover, it is set as the structure which detects the inclination condition of the moving vehicle body 5, and operates a raise control means, The example is shown in FIG. As the lift switch 25 is moved upward, the vehicle body tilt detection sensor 27 detects the left / right tilt state, and when the tilt in either the left or right direction is greater than or equal to the angle α, the lift restricting means is activated. After the alarm is output to the alarm buzzer 23 and the left / right inclination direction is determined by analyzing the detection signal of the vehicle body inclination detection sensor 27, the left / right rolling cylinders 4L, 4R are extended / retracted to bring the vehicle body into a substantially horizontal state. When the angle α is reached, the output from the ascending restriction means is canceled and the tank cylinder mechanism 13 is extended. When the grain storage tank 8 reaches the highest position, the operation of the tank cylinder mechanism 13 is stopped, and the open / close switch 24 is operated to open and output the discharge shutter 15. Thus, when the left / right inclination angle is equal to or greater than the predetermined range, the extension output of the tank cylinder mechanism 13 is restricted by the rise restricting means.
[0025]
Furthermore, the control part 17 performs control shown in the flowchart of FIG. That is, the right / left tilt control is executed to realize a state in which the time for discharging the grain in the tank is shortened or there is no residual grain, while ensuring safety, according to the left / right tilt angle of the vehicle body 5 and the storage amount in the storage tank 8. It is. When the elevation switch 25 is turned on and the ascending command signal is input, the vehicle body inclination detection sensor 27 and the grain amount detection sensor 26 are read. First, it is determined whether or not the vehicle body inclination angle is within a preset α, and when it is within the predetermined range and the grain amount is full, the tank cylinder mechanism 13 is extended and output. At the same time, the right rolling cylinder 4R is shortened and output while the left rolling cylinder 4L is extended and output, and the vehicle body 5 is tilted so that the left side is slightly downward (vehicle body tilt angle = −β, α> β). Therefore, when the amount of the grain rises in the full state (Wmax), the load from the grain storage tank 8 on the right side of the vehicle body acts on the vehicle body tilted to the left, so that it is difficult to fall and is safe. Grain discharge is started, and when the amount falls below a predetermined amount (<W1), hydraulic oil is supplied to and discharged from the left and right rolling cylinders so as to return the vehicle body to a horizontal posture (tilt angle = 0), and the grain discharge is continued. When the amount of grain remaining in the tank decreases as the grain discharge further proceeds ( second predetermined amount, <W2, where W2 <W1), hydraulic oil is applied to the left and right rolling cylinders so that the vehicle body inclination angle is lowered to the right. Supply and discharge. If it does in this way, discharge of the grain in a tank will become smooth. When the amount of grain is exhausted, the discharge shutter 15 is closed. When output is lowered by the lift switch 25, the tank cylinder mechanism 13 is shortened and the grain storage tank 8 is lowered and returned to a predetermined position.
[0026]
The operation of the above example will be described. When the combine 1 is moved forward in the field and the planted culm is cut by the reaping unit 9, the chopped cereal is sequentially fed to the threshing unit 6 and shed. Among these, the sizing is supplied to the grain storage tank 8 at the descending stop position via the first lifting cylinder 14.
[0027]
When the storage amount of the grain storage tank 8 reaches the full Wmax, the grain amount detection sensor 26 detects this and blows out a full buzzer outside the figure. The auxiliary worker makes a transporter with a grain tank (for example, a light truck) approach the grain storage tank 8 side surface of the combine and waits. When a worker on the combine operates the lift switch 25 to the ascending side, the tank cylinder mechanism 13 is extended by supplying and discharging the hydraulic oil, and raises the grain storage tank 8 along the columns 10, 10,. When reaching the highest position, the tank cylinder mechanism 13 stops extending and the tank 8 also stops. Next, when the opening / closing switch 24 is opened, the electric motor 16 rotates forward to open the discharge shutter 15. Along with this, the grains in the tank 8 are discharged and transferred to the grain tank of the transport vehicle looking down.
[0028]
As the storage amount W of the grain storage tank 8 decreases from the full Wmax state through W1 and W2, the left and right inclination angles of the vehicle body 5 become slightly lower left and upper right, horizontal, and upper left and lower right as described above. The left and right rolling cylinders 4L and 4R are controlled. When the grain discharge from the grain storage tank 8 is completed, the open / close switch 24 is operated to close and the elevating switch 25 is operated to the descending side. The electric motor 16 rotates in the reverse direction so that the opening / closing shutter 15 is closed, and the grain storage tank 8 is lowered by the shortening operation of the tank cylinder mechanism 13.
[0029]
In the tank cylinder mechanism of the grain storage tank 8, the rising restriction means works by the rising restriction signal from the control unit 17, and the tank is not raised even by operating the raising / lowering switch 25 to the raising side. . The rise restricting means is (1) when the shift operation lever 28 is not in the neutral position, and (2) when the vehicle body is tilted to the left or right by a predetermined angle or more, the restriction is output so that the tank is not raised. Therefore, the combined vehicle body is likely to become unstable due to the tank rising, but when the tank is raised, the stable state of the vehicle body can be selected as much as possible so that the work can be performed safely.
[0030]
In addition to the above (1) and (2) , (3) When the cutting unit 9 is in the working posture, the conditions for the rise restriction by the rise restriction means are, for example, below a predetermined height based on the detection result of the height detection sensor 30. When the threshing clutch is on and the threshing clutch is turned on, that is, when it is assumed that the threshing clutch is in the working state, the rise restricting means regulates the rise of the grain storage tank. (4) Detect whether or not the combined vehicle is moving and regulate the rise while the vehicle is moving. (5) If the grain storage tank 8 itself is in the lowered position and is not in the lowered position The rise is regulated.
[0031]
7 and 8 show another embodiment of the raising mechanism of the grain storage tank 8, and the upper support column 36 is stretched outwardly of the vehicle body 5 toward the upper side with respect to the vertical lower support column 35 standing on the vehicle body 5. Rollers 38 are provided on the left and right ends of the support arms 37 provided in front of and behind the grain storage tank 8, and the rollers 38 are provided on the upper column 36. It is fitted. Intermediate portions of the support arms 37 and 37 are connected to the tank cylinder mechanisms 13 and 13. By doing so, the tank 8 at the grain discharge position can be raised over the side of the vehicle body 5 of the combine 1. For this reason, when the rear part of the transporting vehicle placed next to the combine 1 is brought closest, the discharge cylinder 8c of the tank 8 can be extended to the side of the vehicle body 5, so that it can be brought close to the side of the combine 1 with a margin. , Can prevent contact accidents.
[0032]
9 and 10 show still another embodiment of the raising mechanism of the grain storage tank 8, and the upper column 41 is displaced laterally outside the vehicle body 5 between the lower column 40 and the upper column 41 perpendicular to the vehicle body 5. An intermediate support 42 is provided, and a lower support 40 and an upper support 41 are connected. The grain storage tank 8 is configured to be able to move from the intermediate support column 42 to the upper support column 41. In addition, the structure which supports the tank 8 with respect to a support | pillar so that sliding up and down is possible is the same as that of said example. Even with this configuration, when the rear part of the transport vehicle placed next to the combine 1 is brought closest, the discharge cylinder 8c of the tank 8 can be extended to the side of the vehicle body 5, so that a margin is maintained between the side of the combine 1 and the side. Can approach.
