PROBLEM TO BE SOLVED: To provide a crop-pulling out and harvesting machine having the operation efficiency improved by preventing a conveying belt of a pulling out and conveying device from coming off.SOLUTION: The crop-pulling out and harvesting machine is equipped with a device 1 for raking in stems and leaves of the crop, the pulling out and conveying device 2 equipped with a first transmission mechanism (18, 19, 2a and 2b) comprising a following pulley 18, a driven pulley 19 and a right and left pair of first conveying endless belts 2a and 2b, for pulling out the crops by nipping and conveying the stems and leaves from the raking-in device 1, and moving the first conveying endless belts 2a and 2b in the right and left direction at a nipping force of a prescribed force or more, a cutting device K for cutting the stems and leaves under conveyance by the pulling-out and conveying device 2, a stem and leaf-conveying device 5 for nipping the cut stems and leaves by succeeding the stems and leaves from the pulling-out and conveying device 2, and discharging the stems and leaves to one side in the right and left direction, and an engine 15 for feeding driving forces to these devices. A second transmission mechanism (40, 41, 42) for transmitting the power from the driven pulley 19 to the following pulley 18 is installed in the pulling-out and conveying device 2. As a result, the first conveying endless belts 2a and 2b are prevented from coming off because the driving force transmitted to the following pulley 18 is enlarged.COPYRIGHT: (C)2010,JPO&INPIT【課題】引抜搬送装置の搬送帯が外れることを防止して、作業能率を向上させる作物引抜収穫機の提供である。【解決手段】作物の茎葉掻込装置1と、従動プーリ18、駆動プーリ19、左右一対の第一搬送無端帯2a,2bからなる第一伝動機構(18,19,2a,2b)を備え、掻込装置1から茎葉を挟持し搬送して作物を引き抜き、一定以上の挟持力により第一搬送無端帯2a,2bが左右に移動する引抜搬送装置2と、引抜搬送装置2で搬送中の茎葉の切断装置Kと、切断後の茎葉を挟持し、引抜搬送装置2から引き継ぎ左右一側に排出する茎葉搬送装置5と、これらの装置の駆動力供給用エンジン15とを設けた作物引抜収穫機であって、引抜搬送装置2に駆動プーリ19から従動プーリ18に動力を伝達する第二伝動機構(40,41,42)を設ける。従動プーリ18に伝動される駆動力が大きくなるため第一搬送無端帯2a,2bが外れることを防止できる。【選択図】図4
