次に実施例の作用を述べる。
エンジン２２を始動し、所定の回転数まで上昇させると、この回転がプーリー、ベルト等の伝達手段によって走行用変速装置２１に伝達され、変速レバー３６を操作すると実施例の走行用変速装置２１は走行用ＨＳＴポンプの斜板の角度を変更させて、走行用ＨＳＴモータに無段階に送油量を増減させながら送油し、走行用ＨＳＴモータはミッションケース２０の入力軸に出力し、入力軸の回転がミッションケース２０内の伝動機構を介して車軸２３、２３に出力され、走行装置２を作動させて、走行する。
しかして、走行装置２により走行を開始すると、刈取部４は分草体５により分草し、分草した穀稈を引起装置６の引起ラグ７により引起し、掻込装置８により掻込んで刈刃９で刈取り、刈取った穀稈の株元は株元側穀稈搬送装置１０で、穂先側は穂先側穀稈搬送装置１１で搬送し、この穀稈を株元側穀稈引継搬送装置１７および穂先側穀稈引継搬送装置１８により脱穀装置３の脱穀室に供給する穀稈供給搬送装置１６に引継ぎ、脱穀装置３に供給する。[0015]
Next, the operation of the embodiment will be described.
When the engine 22 is started and increased to a predetermined rotation speed, this rotation is transmitted to the traveling transmission 21 by a transmission means such as a pulley or belt, and when the speed change lever 36 is operated, the traveling transmission 21 of the embodiment changes the angle of the swash plate of the traveling HST pump to supply oil to the traveling HST motor while continuously increasing or decreasing the amount of oil sent, and the traveling HST motor outputs to the input shaft of the transmission case 20, and the rotation of the input shaft is output to the axles 23, 23 via the transmission mechanism in the transmission case 20, operating the traveling device 2 and causing the vehicle to travel.
When the traveling device 2 starts moving, the cutting unit 4 divides the grass using the dividing body 5, the divided stalks are raised by the raising lug 7 of the raising device 6, raked in by the raking device 8 and cut by the cutting blade 9, the base of the cut stalks is transported by the base side stalk conveying device 10 and the tip side by the tip side stalk conveying device 11, and this stalk is handed over to the stalk supplying and conveying device 16 which supplies it to the threshing chamber of the threshing device 3 by the base side stalk taking over and conveying device 17 and the tip side stalk taking over and conveying device 18, and is then supplied to the threshing device 3.

【効果】
本発明は、圃場の穀稈を分草する分草体５と、該分草体５の後側に設けた圃場の穀稈を引き起こす引起ラグ７を有する引起装置６と、該引起装置６の後方に設けた搬送装置と、該搬送装置の始端部側下方に設けた刈刃９とを設けた刈取装置において、少なくとも前記引起装置６は油圧モータ４０で駆動し、前記引起装置６は、車速が所定速度以上のときは車速に同調して回転数を増減駆動し、車速が零または所定速度以下の低速走行のときは予め設定した所定回転であって前記車速が所定速度を越えたときの回転数より低く駆動するように構成したコンバイン等の刈取装置としたものであるから、作業開始時の車速が零または所定速度以下の低速走行のときでも、引起装置６の引起ラグ７は円滑・確実に穀稈を引き起こせ、畦際や条合せなどの走行速度が所定速度以下のときでも、引起装置６の引起ラグ７の引起しが充分に作用するので、掻込装置８による掻込前のヘッドロスを防止でき、刈刃９による刈跡も美麗となり、また、株元側穀稈搬送装置１０および穂先側穀稈搬送装置１１による穀稈の搬送姿勢も良好となって、株元側穀稈引継搬送装置１７および穂先側穀稈引継搬送装置１８への引継ぎ、および、株元側穀稈引継搬送装置１７および穂先側穀稈引継搬送装置１８から穀稈供給搬送装置１６への引継ぎも良好となって引継部でのロスを防止でき、刈取部４および穀稈供給搬送装置１６での搬送中の稈こぼれを防止でき、脱殻のときの扱き残しを防止して脱穀ロスを減少させる効果を奏し、車速が零または所定速度以下の低速走行のとき、引起装置６を所定回転で駆動させるので、引起装置６以外の刈取部４は当初より回転させるのではなく、車速が零のとき停止させ、車速に比例させて回転を上昇させることができ、機体の走行速度と穀稈の搬送速度を一致させて搬送姿勢を良好にするという効果も期待できるだけでなく、刈取部４を停止させるので、省エネルギー化できるという効果も奏する。[0025]
【effect】
The present invention relates to a harvesting device comprising a grass dividing body 5 for dividing stalks in a field, a lifting device 6 having a lifting lug 7 for lifting the stalks in the field provided behind the grass dividing body 5, a transport device provided behind the lifting device 6, and a cutting blade 9 provided below the starting end of the transport device, wherein at least the lifting device 6 is driven by a hydraulic motor 40 , and the lifting device 6 is driven to increase or decrease the rotation speed in synchronization with the vehicle speed when the vehicle speed is equal to or higher than a predetermined speed, and when the vehicle speed is zero or when traveling at a low speed below the predetermined speed, the lifting device 6 is driven to increase or decrease the rotation speed in synchronization with the vehicle speed when the vehicle speed is equal to or higher than a predetermined speed, and Since the harvesting device is a combine harvester or the like that is configured to be driven at a predetermined rotation speed that is lower than the rotation speed when the vehicle speed exceeds the predetermined speed , even when the vehicle speed at the start of work is zero or traveling at a low speed below the predetermined speed, the lifting lug 7 of the lifting device 6 can lift the stalks smoothly and reliably, and even when the traveling speed at the edge of a ridge or at row alignment is below the predetermined speed, the lifting lug 7 of the lifting device 6 can lift the stalks sufficiently, so that head loss before raking by the raking device 8 can be prevented, and the raking by the cutting blade 9 can be performed smoothly. The marks are also beautiful, and the posture of the culms being transported by the base-side culm transport device 10 and the tip-side culm transport device 11 is also good, which allows for smooth transfer to the base-side culm handover transport device 17 and the tip-side culm handover transport device 18, and smooth transfer from the base-side culm handover transport device 17 and the tip-side culm handover transport device 18 to the culm supply transport device 16, preventing losses at the transfer section, preventing culms from spilling during transport in the reaping section 4 and the culm supply transport device 16, and preventing culms from remaining unthreshed during husking. This has the effect of preventing threshing and reducing loss, and when the vehicle speed is zero or a low speed below a predetermined speed, the lifting device 6 is driven at a predetermined rotation speed, so that the reaping section 4 other than the lifting device 6 is not rotated from the beginning but is stopped when the vehicle speed is zero and the rotation can be increased in proportion to the vehicle speed, which not only has the effect of matching the running speed of the machine body with the conveying speed of the straw to improve the conveying posture, but also has the effect of saving energy because the reaping section 4 is stopped.
