Description

【0001】
【発明の属する技術分野】
この発明は、コンバイン等のクローラ走行装置に関し、走行条件に応じて安定した走行を行うようにしたものである。
【0002】
【従来の技術】
駆動スプロケットと張設転輪とクローラフレームに支持された転輪にクローラを巻き回したものが知られている。
【0003】
【発明が解決しようとする課題】
しかしながら、上記従来装置にあっては、カッター装置等のアタッチメントの装着差により、あるいは刈取脱穀した穀粒を一時貯留する貯留装置の重量変化により、あるいは前後進の切り換え操作の際に前後のバランスが崩れてトラブルの原因になっていた。
【0004】
この原因を取り除くためには重心の位置を変えることになるが、前側の転輪は固定式であるので前後位置調整ができない不具合がある。
【0005】
【課題を解決するための手段】
この発明は上記課題に鑑みて提案するものであって、以下のように構成した。即ち、前側の駆動スプロケットと後側の張設転輪とクローラフレームに取り付けられた複数の転輪と、クローラフレームの前端に位置する前側転輪と、クローラフレームの後端に位置する後側転輪との間にクローラを巻き回したコンバイン等のクローラ走行装置において、前記クローラフレーム(4)の前端に前記前側転輪)を有して前後移動自在な前側の調節フレーム(8)を設け、該前側の調節フレーム(8)をクローラフレーム上方に配置した制御シリンダによって前後移動調節できるように構成すると共に、前記クローラフレーム(4)の後端には後側転輪(6)を有して前後移動自在の後側の調節フレーム(10)を設け、該後側の調節フレーム(10)と前記前側の調節フレーム(8)とを前記クローラフレーム(4)の上方に配置したロッド(11)によって連結して前記制御シリンダ(9)によって連動して一体的に前後動するように構成し、前記クローラ走行装置で支持される機体21を左右傾斜及び前後傾斜可能に構成するにあたり、車体(17)の下部に左右一対のクローラフレーム(4)を前後一対の平行リンク(18,19)によって昇降自在に取り付け、機体(21)の前後方向の傾斜角を変更するピッチング軸を前記車体(17)に対する前側の平行リンク(18)の回動支軸上に設けると共にピッチングシリンダ(23)の伸縮によって拡縮リンク(24)を介して車体(17)に対する機体(21)の前後方向の傾斜角を変更できるように構成し、前記機体21が前側方向に前進するときには前記左右両側の前側転輪と後側転輪とを後側に移動させると共に、機体21の左右傾斜と前後傾斜をさせない構成とし、機体21が後側方向に後進するときには前記左右両側の前側転輪と後側転輪とを前側に移動させると共に、機体21を左右傾斜させずに後傾斜させる構成とし、機体21が右旋回するときには右側の前側転輪と後側転輪とを後側に移動させて、左側の前側転輪と後側転輪とを前側に移動させると共に、機体21を右側に傾斜させて、機体21の前後傾斜をさせない構成とし、機体21が左旋回するときには左側の前側転輪と後側転輪とを後側に移動させて、右側の前側転輪と後側転輪とを前側に移動させると共に、機体21を左側に傾斜させて、機体21の前後傾斜をさせないように構成したことを特徴とするコンバイン等のクローラ走行装置の構成とする。
【0006】
【発明の作用】
コンバインの後部にアタッチメントを付けたり、貯留装置内に貯留された脱穀穀粒の重量の増加によって、あるいは機体の前後進の切り換え操作の際に例えば機体21前部が上方に傾いたときには前側転輪3を後方へ移動させ、反対に重心が前方にずれて機体21前部が下向に傾いたときにはこの転輪3を前方に移動させて機体前後のバランスをとる。そして、クローラ走行装置が前進走行時は左右両側の前側転輪5と後側転輪6は共に後位に移動し、後進走行時は左右両側の前側転輪5と後側転輪5は共に前方に移動する。
機体21が前側方向に前進するときには前記左右両側の前側転輪5と後側転輪6とを後側に移動させ、機体21の左右傾斜と前後傾斜をさせない。
機体21が後側方向に後進するときには前記左右両側の前側転輪5と後側転輪6とを前側に移動させ、機体21を左右傾斜させずに後傾斜させる。
機体21が右旋回するときには右側の前側転輪5と後側転輪6とを後側に移動させ、左側の前側転輪5と後側転輪6とを前側に移動させる。さらに、機体21を右側に傾斜させて、機体21の前後傾斜をさせない。
機体21が左旋回するときには左側の前側転輪5と後側転輪6とを後側に移動させ、右側の前側転輪5と後側転輪6とを前側に移動させる。さらに、機体21を左側に傾斜させて、機体21の前後傾斜をさせない。
【0007】
【発明の効果】
この発明は前述の通りに構成されるので、前側の第一転輪3を移動させることにより走行中の機体前後バランスの改善を図ることができる。
しかも、第一転輪3を移動させる伸縮装置9はクローラフレーム4の上方に設けられているので、湿田での作業時にも泥土等が掛かりにくいという特徴がある。そして、車体の移動による機体の沈下を防止できるようになり、旋回性も向上するようになる。さらに、機体が安定するようになる。
また、前進時、後進時、右旋回時及び左旋回時のいずれの場合においても、機体21は安定して走行可能となる。
【0008】
【発明の実施の形態】
以下、図に基づいて、この発明の実施例を説明する。図1〜図3において、コンバインの車体17の下部には、左右一対のクローラフレーム4が平行状にして、前後一対の平行リンク18,19で昇降自在に取り付けられ、各クローラフレーム4には転輪3、張設転輪7等と、車体17側前端の駆動スプロケット2との間に亘ってゴム製のクローラ1を巻き掛けてクローラ形態の走行装置を構成している。
【0009】
該各クローラフレーム4の前端には、前側転輪(第一転輪)5を有して前後移動自在な調節フレーム8を設けてこの調節フレーム8をクローラフレーム4に対して油圧伸縮式の制御シリンダ9で前後移動調節すべく設け、又、クローラフレーム4の後端には後側転輪6を有して前後移動自在の調節フレーム10を設け、この調節フレーム10と前記調節フレーム8とをロッド11で連結して制御シリンダ9によって連動して一体的に前後動する構成としている。図1からわかるように油圧式制御シリンダ9及びロッド11はクローラフレーム4に対して上方に配設されている。
【0010】
駆動スプロケット2と前側転輪5との位置関係は、駆動スプロケット2に対して前側転輪5が後下方にあって、これらの間に張圧されるクローラ1が接地面に対してAの傾斜角を有する。張設転輪7と後側転輪6との関係についても同様にしてBの傾斜角を有する。この張設転輪7は調節棒12によってクローラフレーム4に一体のボス部13に対して前後摺動自在に支持されて、ばねによって常時後方へ張圧されている。
【0011】
制御シリンダ9を伸縮する油圧回路の伸縮制御弁への出力制御の構成は、マイクロコンピュータを有するコントローラからの電磁作動出力によって行わせるもので、図3の表で示すような関係に設定している。
即ち、前進走行時は左右両側の前側転輪5、後側転輪6共に後位にあって傾斜角Aは小さく、Bは大きくなり、駆動反力、あるいは車体後部の重心移動による機体後部の沈下を防止する関係にある。逆に後進走行時は、左右両側の前側転輪5、後側転輪6共に前方に移動して駆動反力、あるいは重心移動による機体前部の沈下を防止する。又、右旋回するときはこの旋回操作に連動して右前側の転輪5と後側転輪6とが後方に移動されると共に、左前側転輪5と後側転輪6とが前方に移動されて旋回側のクローラ1の接地面を後方に移動させることによって旋回性を良くする。このとき、右旋回側のクローラ1の傾斜角Aが小さくなるため、湿田での横すべりが行われ易く旋回が容易である。左旋回においては同様にして左側のクローラ1の接地面が右側のクローラ1の接地面よりも後方に移動される。16はクローラフレーム4に支持させた上部転輪、25は伝動ケースで左右のスプロケット2を駆動する伝動装置を内装している。
【0012】
又、図3に示すように車体17のローリング制御又はピッチング制御との関係を設定すると良い。ローリング制御は車体17に対して左右一対のクローラフレーム4を各ローリングシリンダ20の伸縮により平行リンク18,19を介して上下動させて耕盤等の左右の傾斜にも拘わらずクローラフレーム4の上下動によって車体17、及びこの上部の機体21を左右水平状に姿勢維持すべく制御するものであるが、これを前進又は後進時は車体17に対して左右のクローラフレーム4が同じ高さである平行状態になるように制御し、又、右旋回又は左旋回時には、これら旋回側の車体17の高さが低くなるように右傾斜又は左傾斜となるように制御することにより旋回性を容易化し、機体21の安定を維持できる。22は平行リンク18,19のリンクアーム間を連結するロッドである。
【0013】
又、ピッチング制御は車体17に対してこの上側に支持される機体21が前後方向の傾斜角を変更するようにピッチングシリンダ23の伸縮により拡縮リンク24を介して制御されるものであるが,機体21が車体17又はクローラフレーム4に対して前後方向に平行状態にあるとき、ピッチング制御が最も前下りの状態にあるものとすれば前進時は平行状態とし、後進時は後下がりの状態とする。又,右旋回、及び左旋回時は平行状態とする。ピッチング軸は、車体17に対する平行リンク18の回動支軸24上に設けている。

Further, the airframe 21 can travel stably in any case of forward, reverse, right turn and left turn.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1 to FIG. 3, a pair of left and right crawler frames 4 are attached in parallel to the lower part of the combiner body 17 and can be moved up and down by a pair of front and rear parallel links 18 and 19. A crawler-type traveling device is configured by winding a rubber crawler 1 between the wheel 3, the tension roller 7 and the like and the drive sprocket 2 at the front end of the vehicle body 17 side.
[0009]
At the front end of each crawler frame 4, there is provided an adjustment frame 8 having a front wheel (first wheel) 5 that is movable back and forth, and this adjustment frame 8 is hydraulically telescopically controlled with respect to the crawler frame 4. The cylinder 9 is provided to adjust the longitudinal movement, and the rear end of the crawler frame 4 is provided with an adjustment frame 10 having a rear wheel 6 that can be moved forward and backward, and the adjustment frame 10 and the adjustment frame 8 are connected to each other. The rod 11 is connected and interlocked by the control cylinder 9 so as to integrally move back and forth. As can be seen from FIG. 1, the hydraulic control cylinder 9 and the rod 11 are disposed above the crawler frame 4.
[0010]
The positional relationship between the drive sprocket 2 and the front wheel 5 is such that the front roller 5 is located rearward and lower with respect to the drive sprocket 2 and the crawler 1 tensioned between them is inclined A with respect to the ground plane. Has horns. Similarly, the relationship between the tension roller 7 and the rear roller 6 has an inclination angle B. The tension roller 7 is supported by an adjustment rod 12 so as to be slidable back and forth with respect to a boss portion 13 integral with the crawler frame 4 and is always tensioned backward by a spring.
[0011]
The configuration of the output control to the expansion / contraction control valve of the hydraulic circuit that expands / contracts the control cylinder 9 is performed by an electromagnetic operation output from a controller having a microcomputer, and is set to the relationship shown in the table of FIG. .
That is, when traveling forward, both the front and rear wheels 5 and 6 on the left and right sides are in the rear position, the inclination angle A is small, B is large, and the rear part of the body is driven by the driving reaction force or the center of gravity movement of the rear part of the vehicle body. It has a relationship to prevent settlement. Conversely, during reverse travel, both the front and rear wheels 5 and 6 on both the left and right sides move forward to prevent driving reaction force or the sinking of the front part of the body due to the movement of the center of gravity. When turning right, the right front wheel 5 and the rear wheel 6 are moved rearward in conjunction with the turning operation, and the left front wheel 5 and the rear wheel 6 are moved forward. The swirlability is improved by moving the ground contact surface of the crawler 1 on the swivel side backward. At this time, since the inclination angle A of the crawler 1 on the right turn side is small, it is easy to make a side slip in the wet paddy field and to turn easily. In the left turn, similarly, the contact surface of the left crawler 1 is moved rearward from the contact surface of the right crawler 1. Reference numeral 16 denotes an upper wheel supported by the crawler frame 4, and 25 denotes a transmission case that includes a transmission device that drives the left and right sprockets 2.
[0012]
Also, as shown in FIG. 3, the relationship with rolling control or pitching control of the vehicle body 17 may be set. In the rolling control, a pair of left and right crawler frames 4 with respect to the vehicle body 17 is moved up and down through parallel links 18 and 19 by expansion and contraction of each rolling cylinder 20, and the crawler frame 4 is moved up and down regardless of the left and right inclination of a tilling board or the like. The vehicle body 17 and the upper body 21 are controlled by movement so as to maintain the horizontal posture in the horizontal direction. The left and right crawler frames 4 are at the same height with respect to the vehicle body 17 when moving forward or backward. It is controlled to be parallel, and when turning right or left, turning performance is easy by controlling the vehicle body 17 on the turning side so that it is inclined right or left so that the height of the vehicle body 17 is lowered. And the stability of the airframe 21 can be maintained. A rod 22 connects the link arms of the parallel links 18 and 19.
[0013]
The pitching control is controlled via the expansion / contraction link 24 by the expansion and contraction of the pitching cylinder 23 so that the airframe 21 supported on the upper side with respect to the vehicle body 17 changes the inclination angle in the front-rear direction. When 21 is parallel to the vehicle body 17 or the crawler frame 4 in the front-rear direction, assuming that the pitching control is in the most forward-down state, the forward state is the parallel state, and the reverse side is the rear-lower state. . When turning right and turning left, it is in a parallel state. The pitching shaft is provided on the rotation support shaft 24 of the parallel link 18 with respect to the vehicle body 17.
