Description
【0001】[0001]
本考案は、コンバインやバインダ等の刈取部に設けられる茎稈引起し装置に関 する。 The present invention relates to a stem-culm raising device provided in a harvesting part such as a combine or a binder.
【0002】[0002]
従来、この種の茎稈引起し装置は、走行速度に同調する状態で引起し速度を一 定にしていた。 Conventionally, this type of stem culm raising device has fixed the raising speed in a state of being synchronized with the traveling speed.
【0003】[0003]
従って、上記従来のものにあっては、倒伏穀稈を引き起こす際に、低速で引き 起こしていくと、引起し爪に係止される穀稈量が多くなりそのため梳き上げの際 に重なった状態の穀稈が爪から逃げずに圃場面から引き抜かれてしまうという不 具合が生じ易いものであった。 Therefore, in the case of the above-mentioned conventional ones, when the fallen grain culms are caused to be raised at a low speed, the amount of grain culm that is pulled up and locked by the claws increases, and therefore, the state of overlapping at the time of combing The grain culm of this crop was easily pulled out of the field without escaping from the nails.
【0004】 本考案は、上記実情に鑑みてなされたものであって、引起し爪の負荷の大小に 応じて、引起し速度の増減の切り換えを自動的に行うことのできる茎稈引起し装 置の提供を目的とする。The present invention has been made in view of the above-mentioned circumstances, and a stem-culm raising device capable of automatically changing the increase and decrease of the raising speed according to the load of the raising nail. The purpose is to provide storage.
【0005】[0005]
本考案にかかる茎稈引起し装置は、上記目的を達成するために、駆動プーリと 、割りプーリから成る従動プーリとにわたって伝動ベルトを巻回して構成したベ ルト式無段変速装置を、引起し装置の駆動系に設けるとともに、前記従動プーリ を拡径方向に弾性付勢してあることを特徴構成とする。 かかる特徴構成による作用・効果は次の通りである。 In order to achieve the above object, a stem culm raising device according to the present invention raises a belt type continuously variable transmission constituted by winding a transmission belt around a drive pulley and a driven pulley composed of a split pulley. In addition to being provided in the drive system of the apparatus, the driven pulley is elastically biased in the radial direction. The actions and effects of this characteristic configuration are as follows.
【0006】[0006]
即ち、引起し装置において倒伏穀稈等を掻き上げる場合に、引起し爪で掻き上 げる穀稈量が多くなって引起し装置での負荷が大きくなると、ベルト式無段変速 装置の従動プーリにおけるベルト巻き掛け径が小さくなるので、引起し装置を高 速で駆動するようになる。高速で引起し装置が駆動されると、引起し爪に掻き上 げられる穀稈量が減少して、穀稈が捌かれ易くなり、この捌かれてばらついた状 態の穀稈を掻き上げることになるから、穀稈を引き抜くことが無くなる。 In other words, when scraping up fallen grain culms, etc. in the raising device, if the amount of grain culms that can be scratched up by the raising claws increases and the load on the raising device increases, the driven pulley of the belt-type continuously variable transmission device Since the belt wrapping diameter at is small, the raising device can be driven at high speed. When the raising device is driven at high speed, the amount of grain culm scratched by the raising nail decreases, and the grain culms are easier to handle, and the grain culms in a loose and scattered state are scraped up. Therefore, there is no need to pull out the grain culm.
【0007】[0007]
従って、本考案によれば、引起しの際の負荷に応じて引起し装置の速度が自動 的に変動するようにできたので、圃場での穀稈状態に応じて穀稈の引起しが常に 良好に行われるに至った。 Therefore, according to the present invention, since the speed of the raising device can be automatically changed according to the load at the time of raising, the raising of the grain culm is always performed according to the state of the grain culm in the field. It went well.
【0008】[0008]
以下、本考案の実施例を図面に基づいて説明する。 図3に、本考案にかかる茎稈引起し装置を備えたコンバインの刈取前処理部1 を示している。 このコンバインの刈取前処理部1は、伝動ケースに兼用された支持フレーム3 を、走行機体2の前部で上下揺動自在に支持させているとともに、穀稈を分草す る分草具4を前端部に備えた分草杆5を前方に延出した状態で支持し、分草され た穀稈を引き起こす左右一対の引起し装置6,6を後傾斜姿勢に立設して、かつ 、引起された穀稈の株元部を刈り取る刈取装置7を穀稈導入路に左右に架設し、 刈取穀稈を後方に搬送する搬送装置8を備えて構成している。 Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 shows a combine pre-mowing pretreatment unit 1 equipped with a stem-culm raising device according to the present invention. The harvesting pretreatment unit 1 of this combine has a support frame 3 also used as a transmission case, which is supported by a front portion of a traveling machine body 2 so as to be vertically swingable, and a weeding tool 4 for weeding culms. Supporting a weeding rod 5 provided at the front end in a state of being extended forward, and setting up a pair of left and right raising devices 6 and 6 for raising the weeded culm in a rearwardly inclined posture, and A reaping device 7 for reaping the root portion of the raised grain culm is erected on the left and right sides of the grain culm introduction path, and is provided with a transport device 8 for conveying the harvested grain culm backward.
【0009】 そして、図1に示すように、3本の分草杆5のうち、最も未刈がわに位置する 分草杆5は、その支持フレーム3への連結基端部を上下軸心P周りで左右揺動可 能に取り付けており、これによって、畦際での刈取作業において走行機体2を畦 近くに寄せることが困難であるときに、機体外側方に分草具4を偏位させて、畦 際の穀稈列をも刈取前処理部1に導入して刈り取れるようにするのである。なお 、分草杆5の所定姿勢での保持固定は、図1に示すように、分草杆5の基部の融 通長孔を通してボルト9を固定することでなされる。この他、分草杆5の所定姿 勢での保持固定を、ボールデテント機構を利用しても良いし、運転席からの操作 で分草杆5を自動的に外側方に偏位させたり、通常位置に戻せるよう、分草杆5 の揺動駆動を電動モータ等のアクチュエータを利用して行っても良い。Then, as shown in FIG. 1, among the three weed rods 5, the weed rod 5 located at the most uncut area has its base end connected to the support frame 3 at the vertical axis. It is attached so that it can swing to the left and right around P. This makes it possible to shift the weeding tool 4 to the outside of the machine when it is difficult to move the traveling machine 2 close to the ridge during mowing work on the ridge. Then, the grain culm row at the edge of the ridge is also introduced into the pre-mowing processing unit 1 so that it can be cut. The holding and fixing of the weed rod 5 in a predetermined posture is carried out by fixing the bolt 9 through a long, elongated hole in the base of the weed rod 5, as shown in FIG. In addition, a ball detent mechanism may be used to hold and fix the grass rod 5 in a predetermined posture, or the grass rod 5 may be automatically deviated to the outer side by an operation from the driver's seat. The swinging rod 5 may be driven to swing so as to return to the normal position by using an actuator such as an electric motor.
【0010】 次に、引起し装置6,6への伝動系構造について説明する。 図1及び図2に示すように、支持フレーム3によって立設支持した各引起し装 置6,6は、支持フレーム3に内装された伝動機構より、各引起し6,6の後部 に連設されたベルト式無段変速装置10を介して動力伝達されている。すなわち 、支持フレーム3に内装された伝動機構からの動力は、ベルト式無段変速装置1 0の駆動プーリ11に伝えられるとともに、駆動プーリ11と従動プーリ12と に巻回した伝動ベルト13により従動プーリ12が駆動され、従動プーリ12と 直結した引起し装置6の駆動スプロケット14が駆動されることになる。そして 、駆動スプロケット14と、この駆動スプロケット14に対して引起しケース下 端部に設けられた遊転スプロケット15とにわたって巻回した引起し爪付きチェ ーン16がその引起し爪で穀稈を引起す状態で回転駆動されることになる。 ベルト式無段変速装置10の従動プーリ12は、図2に示すように、割りプー リで構成されており、伝動軸17に対して一体固定された固定半割りプーリ12 Aと、この固定半割りプーリ12Aに対して伝動軸17の軸心方向に遠近移動可 能に設けた可動半割りプーリ12Bと、この可動半割りプーリ12Bを固定半割 りプーリ12Aに向けて押圧して有効巻掛け径を拡大する方向に付勢するスプリ ング18とで構成している。また、伝動ベルト13にテンションを与えるテンシ ョンアーム19をベルト緊張がわに弾性付勢された状態に設けている。Next, the structure of the transmission system to the raising devices 6 and 6 will be described. As shown in FIGS. 1 and 2, the raising devices 6 and 6 standingly supported by the support frame 3 are connected to the rear portions of the raising devices 6 and 6 by a transmission mechanism installed in the support frame 3. The power is transmitted via the belt type continuously variable transmission 10. That is, the power from the transmission mechanism installed in the support frame 3 is transmitted to the drive pulley 11 of the belt type continuously variable transmission 10, and is driven by the transmission belt 13 wound around the drive pulley 11 and the driven pulley 12. The pulley 12 is driven, and the drive sprocket 14 of the raising device 6 directly connected to the driven pulley 12 is driven. Then, the chain 16 with the raising claw that is wound around the drive sprocket 14 and the idle sprocket 15 that is raised with respect to the drive sprocket 14 and that is provided at the lower end of the case is used to pull the grain culms with the raising claw. It will be rotationally driven in the raised state. As shown in FIG. 2, the driven pulley 12 of the belt type continuously variable transmission 10 is composed of a split pulley, and a fixed half split pulley 12A integrally fixed to the transmission shaft 17 and this fixed half pulley. A movable half-split pulley 12B provided so as to be movable in the axial direction of the transmission shaft 17 with respect to the split pulley 12A, and the movable half-split pulley 12B is pressed toward the fixed half-split pulley 12A for effective winding. It is composed of a spring 18 that urges in a direction to increase the diameter. Further, a tension arm 19 for applying a tension to the transmission belt 13 is provided in a state where the belt tension is elastically biased.
【0011】 従って、上記構成によれば、例えば倒伏穀稈を引起すような場合に、引起し負 荷が増大すると、伝動ベルト13の張力が増大するようになって、これにより、 伝動ベルト13が従動プーリ12における可動半割りプーリ12Bをスプリング 18に抗して押し広げて小さい巻き掛け径で従動プーリ12に巻き掛けられるこ とになる。その結果、駆動プーリ11に対して従動プーリ12での巻き掛け径が 小となることで従動プーリ12の回転速度が増すことになり、引起し装置6を高 速駆動するようになる。Therefore, according to the above configuration, for example, when the fallen grain culm is caused, the tension of the transmission belt 13 is increased when the load caused by the raising is increased, whereby the transmission belt 13 is increased. Will spread the movable half pulley 12B of the driven pulley 12 against the spring 18 and wind it around the driven pulley 12 with a small winding diameter. As a result, the winding diameter of the driven pulley 12 becomes smaller than that of the drive pulley 11, so that the rotation speed of the driven pulley 12 increases, and the pulling device 6 is driven at high speed.
