Description

この発明は、圃場内の植立穀稈を刈り取って脱穀機内へ移送する穀稈移送装置を備えるコンバインに関する。   The present invention relates to a combine equipped with a culm transfer device that cuts and transfers planted culm in a field into a threshing machine.

コンバインでの植立穀稈の収穫作業は、コンバインを圃場で走行させて、走行車台の前側に設けた刈取装置の前部で、下方から後上方に向けて設けたナローガイドと分草体で植立穀稈が条分けされ、この条分けした穀稈が複数の掻込移送装置で掻込まれながら刈刃装置で株元を刈り取られ、各条の穀稈を株元移送装置と穂先移送装置と搬送し、合流させて供給移送装置へ挟持移送される。供給移送装置から脱穀機に搬送される穀稈は、搬送途中に穀稈の穂先位置が脱穀機の適正供給位置となるよう株元挟持位置を調整されて、脱穀機のフィードチェンと挟持杆へ引継がれて穀稈の穂先側が脱穀機の供給口から内部へ供給され、フィードチェンと挟持杆とで株元側を挟持された穀稈が後方へ送られながら穂先側が脱穀機内を通過する間に脱穀される。脱穀機内で脱穀し選別された穀粒は、この脱穀機の横側へ設けた穀粒貯留タンク内へ供給されて、一時貯留される。   The harvesting work of the planted cereal with the combine is carried out by driving the combine in the field and planting with a narrow guide and a herbaceous body provided from the lower part to the rear upper part at the front part of the cutting device provided on the front side of the traveling chassis. Standing cereals are divided into strips, and the cereals are cut by a cutting blade device while being squeezed by a plurality of scraping transfer devices. Are conveyed and merged and nipped and transferred to the supply and transfer device. The cereals conveyed from the supply transfer device to the threshing machine are adjusted to the stock holding position so that the tip position of the cereal is the proper supply position of the threshing machine during the transfer, and then to the feed chain and the holding bowl of the threshing machine While the head of the cereal is passed to the inside through the feed port of the threshing machine, while the cereal with the stock side held between the feed chain and the holding bowl is fed backward, the tip side passes through the threshing machine Threshed. The grains threshed and selected in the threshing machine are supplied into a grain storage tank provided on the side of the threshing machine and temporarily stored.

前記供給移送装置は、特許文献１に例示するように、供給移送装置に着脱自在な掻込支持装置を備えるとともに、供給移送装置の上側に穀稈の穂先が浮き上がらないように掻込支持装置に備える穂先挟持杆によって穂先を押え込み、穀稈の搬送姿勢を安定させる技術が知られている。   As illustrated in Patent Document 1, the supply and transfer device includes a scraping support device that is detachable from the supply and transfer device, and the scraping support device is arranged so that the tip of the cereals does not float above the supply and transfer device. A technique is known in which the tip is pressed by the tip pinching rod provided to stabilize the conveying posture of the cereal.

しかしながら、上記特許文献に記載されたような従来技術においては、刈取穀稈は、株元移送装置と穂先移送装置とで引継ぎ移送部に集められてさらに穂先位置を脱穀機供給口供給位置に調整され、さらにフィードチェンと挟持杆で株元を挟持されて後方へ搬送される間に穀稈の穂先側が脱穀機の供給口から内部に引き込まれて脱穀されるが、引継ぎ移送部で、穀稈の姿勢を刈取姿勢である縦姿勢から、脱穀機へ挿入する横姿勢へと変更しながら搬送する構成である為に、刈取速度が速くなると穂先側が横姿勢とならないまま供給口へと移送されてしまい、脱穀機の供給口に多くの刈取穀稈が供給されて穀稈の穂先部分が脱穀機の供給口周囲に衝突することで穀粒が脱粒し、機外に飛散して収量が低減する問題がある。また、穀稈の詰まりを解消するため掻込支持装置の着脱する際に、穂先挟持杆が支持杆に引掛かり着脱作業の妨げとなる上、穂先挟持杆の変形や破損を招く問題がある。   However, in the prior art as described in the above patent document, the harvested cereal meal is collected in the takeover transfer unit by the stock transfer device and the tip transfer device, and the tip position is further adjusted to the threshing machine supply port supply position. Furthermore, while the stock head is held between the feed chain and the holding rod and conveyed backward, the tip side of the kernel is drawn into the inside from the supply port of the threshing machine and threshed. Therefore, when the cutting speed increases, the tip side is transferred to the supply port without being in the horizontal position because the posture is changed from the vertical position that is the cutting position to the horizontal position to be inserted into the threshing machine. Therefore, a lot of harvested cereals are supplied to the supply port of the threshing machine, and the grain part is shattered when the tip part of the cereal collides with the periphery of the supply port of the threshing machine. There's a problem. In addition, when attaching and detaching the rake support device in order to eliminate clogging of the cereals, there is a problem that the tip pinch hook is hooked on the support hook and hinders the attachment / detachment work, and the tip pinch punch is deformed or broken.

本発明は、脱穀機の供給口で盛り上がる穀稈の穂先側を押えて脱穀機内に入り易くして、供給口周囲に当たって脱粒する穀粒を少なくして収穫する穀粒の収量ロスを低減すると共に、掻込支持装置の着脱を容易にすることを課題とする。   The present invention makes it easy to enter the threshing machine by pressing the tip side of the cereal that rises at the supply port of the threshing machine, and reduces the yield loss of the grain to be harvested by reducing the number of grains that hit the periphery of the supply port. It is an object of the present invention to facilitate attachment / detachment of the scraping support device.
