ここで、両振動体21を振動させる第２伝動手段24は、第１伝動手段19に接続され支軸25を中心として回転する第１回転体である第１プーリ26を有するとともに、この第１プーリ26に離間対向して配設され支軸27を中心として回転する第２回転体である第２プーリ28を有し、両プーリ26，28間には無端体であるベルト29が巻き掛けられている。   Here, the second transmission means 24 that vibrates both vibration bodies 21 includes a first pulley 26 that is connected to the first transmission means 19 and rotates around the support shaft 25, and this first pulley 26. A second pulley 28, which is a second rotating body that is disposed so as to face and separate from the pulley 26 and rotates about the support shaft 27, is provided, and an endless belt 29 is wound between the pulleys 26, 28. ing.

第２プーリ28には、図６に示されるように、支軸27からの距離がそれぞれ異なる複数、例えば３つの連結部である孔部30が設けられ、これら３つの孔部30の中から選択された一の孔部30には第１アーム31の一端部が回転可能に連結されている。なお、第１アーム31を連結する孔部30の選択により、振動体21の振れ角度αが例えば５度〜２０度の範囲で調節可能となっている。   As shown in FIG. 6, the second pulley 28 is provided with a plurality of hole portions 30, for example, three connecting portions, each having a different distance from the support shaft 27, and can be selected from these three hole portions 30. One end of the first arm 31 is rotatably connected to the one hole 30 formed. Note that the deflection angle α of the vibrating body 21 can be adjusted within a range of, for example, 5 degrees to 20 degrees by selecting the hole 30 connecting the first arm 31.

第１アーム31の他端部には第２アーム32の一端部が回動可能に連結され、この第２アーム32の他端部は支軸23の下部に回動可能に連結されている。第２アーム32の中間部には連結バー33が連結され、この連結バー33の長手方向両端部からは連結杆34が立ち上がっている。連結杆34の上端部には連結板35の一端側が回動可能に連結され、この連結板35の他端が振動体21の後端側に固着されている。第２アーム32と連結バー33とは、第２アーム32の孔部36と連結バー33にその孔部36より大きく形成された孔部37とにピン38が差し込まれることにより連結されている。   One end of the second arm 32 is rotatably connected to the other end of the first arm 31, and the other end of the second arm 32 is rotatably connected to the lower portion of the support shaft 23.

The second arm 32 and the connecting bar 33 are connected by inserting a pin 38 into the hole 36 of the second arm 32 and the hole 37 formed larger than the hole 36 in the connecting bar 33.

なお、図４から明らかなように、振動体21の前端は、掘取コンベヤ12の前方で掘取刃20の掘取に先立って畝を柔軟にできるように掘取コンベヤ12の前端つまり掘取刃20の前端より前方に配設されている。すなわち、振動体21の前端部は、先細状に形成され、畝Ａを崩す振動刃部40となっている。   As is clear from FIG. 4, the front end of the vibrating body 21 is located at the front end of the digging conveyor 12, that is, in front of the digging conveyor 12, so that the dredging can be made flexible before the digging blade 20 is dug. The blade 20 is disposed in front of the front end. That is, the front end portion of the vibrating body 21 is formed in a tapered shape, and is a vibrating blade portion 40 that breaks the flange A.

また、振動体21は支軸23の近傍位置で若干屈曲しており、左右一対の振動体21は、平面視で後端ほど離間距離が短い略ハ字状に位置する。すなわち、振動体21は支軸23の近傍位置に屈曲部21aを有し、振動体21の屈曲部21aより前側の部分が第１振動部21bとなっており、振動体21の屈曲部21aより後側の部分が第２振動部21cとなっており、第２振動部21cが平面視で後端ほど離間距離が短い略ハ字状に位置する。   The vibrating body 21 is slightly bent in the vicinity of the support shaft 23, and the pair of left and right vibrating bodies 21 are positioned in a substantially C shape with a shorter separation distance toward the rear end in plan view.

The rear portion is the second vibrating portion 21c, and the second vibrating portion 21c is positioned in a substantially C shape with a shorter separation distance toward the rear end in plan view.

また一方、機枠２には、農作物Ｗの本体部Ｗ1を左右両側から挟持した状態で農作物Ｗを立ち姿勢のまま斜め後上方に向けて挟持搬送する前下り傾斜状のベルト式の挟持コンベヤ41が設けられているとともに、水平方向の回動軸42を中心として回転することにより挟持コンベヤ41にて搬送中の農作物Ｗの根部Ｗ2に付着した土を除去する土除去手段である土除去ローラ43が設けられている。   On the other hand, the machine frame 2 has a belt-type sandwiching conveyor 41 that is inclined forward and downward so that the crop W is sandwiched and conveyed obliquely rearward and upward while holding the main body W1 of the crop W from both the left and right sides. And a soil removal roller 43 which is a soil removal means for removing the soil adhering to the root W2 of the crop W being conveyed by the sandwiching conveyor 41 by rotating about a horizontal rotation shaft 42. Is provided.

なお、挟持コンベヤ41の前端部は、掘取コンベヤ12の上方に配設されている。土除去ローラ43は、第１伝動手段19側からの動力に基づいて回転するもので、掘取コンベヤ12の後方に配設されている。   The front end portion of the sandwiching conveyor 41 is disposed above the digging conveyor 12. The soil removal roller 43 is rotated based on the power from the first transmission means 19 side, and is disposed behind the digging conveyor 12.

挟持コンベヤ41は、軟質ゴム等にて構成された左右一対の挟持ベルト45を有し、挟持ベルト45は、複数のローラ46に巻き掛けられ、第１伝動手段19側からの動力に基づいて回行する。   The sandwiching conveyor 41 has a pair of left and right sandwiching belts 45 made of soft rubber or the like. The sandwiching belt 45 is wound around a plurality of rollers 46 and rotates based on the power from the first transmission means 19 side. To do.

また、挟持コンベヤ41の後端部に隣接して載置台（図示せず）が配設されている。さらに、機枠２には１つの前輪47および２つの後輪48が設けられている。   Further, a mounting table (not shown) is disposed adjacent to the rear end portion of the sandwiching conveyor 41. Further, the machine casing 2 is provided with one front wheel 47 and two rear wheels 48.

次に、上記農作業機１を使用して収穫作業をする場合について説明する。   Next, the case where a harvesting operation is performed using the agricultural machine 1 will be described.

トラクタに連結した状態でトラクタの走行により農作業機１全体を前方に移動させると、図８および図９に示すように、農作物Ｗは、掘取コンベヤ12にて掘り取られるとともに、掘取コンベヤ12および挟持コンベヤ41にて斜め後上方に向けて搬送され、その後、載置台上に載置される。   When the entire farm work machine 1 is moved forward by traveling of the tractor while being connected to the tractor, as shown in FIGS. 8 and 9, the crop W is dug by the digging conveyor 12 and the digging conveyor 12. Then, it is conveyed obliquely rearward and upward by the sandwiching conveyor 41, and then placed on the placing table.

この際、左右一対の振動体21は、図７に示すように、第２伝動手段24側からの動力に基づき、予め設定された振れ角度αをもって支軸23を中心に回動して振動する。このため、２〜４本が束となった複数本の農作物Ｗは、両側方の振動体21にて案内されつつ、掘取コンベヤ12および挟持コンベヤ41にて斜め後上方に向けて搬送され、その途中で振動体21にて左右両側から叩かれるようにして絡んだ根部Ｗ2がほぐされて分離され、かつその根部Ｗ2に付着した土が除去される。なお、振動体21にて除去しきれなかった付着土は、回転する土除去ローラ43で除去される。   At this time, as shown in FIG. 7, the pair of left and right vibrating bodies 21 vibrate by rotating around the support shaft 23 with a preset deflection angle α based on the power from the second transmission means 24 side. . For this reason, a plurality of crops W in which 2 to 4 bundles are guided while being guided by the vibrating bodies 21 on both sides, and are conveyed obliquely rearward and upward by the digging conveyor 12 and the sandwiching conveyor 41, In the middle, the entangled root W2 is loosened and separated by being struck by the vibrating body 21 from the left and right sides, and the soil adhering to the root W2 is removed. The attached soil that could not be removed by the vibrator 21 is removed by the rotating soil removing roller 43.

そして、農作業機１の後ろを追う作業者は、載置台上の農作物Ｗを図示しないシート上に載せかえ、そのシートで農作物Ｗを包み込み、圃場上に置いていく。   Then, the worker who follows the farm machine 1 places the crop W on the mounting table on a sheet (not shown), wraps the crop W with the sheet, and places it on the farm field.

このように上記農作業機１によれば、対をなす振動体21が左右方向に振動し、この振動する振動体21が掘取コンベヤ12にて搬送中の複数の農作物Ｗの絡んだ根部Ｗ2をほぐしながらその根部Ｗ2に付着した土を落すため、根部Ｗ2の付着土を適切に除去できるばかりでなく、作業者が手作業で絡んだ根部Ｗ2をほぐす必要もなく、効率よく収穫作業ができる。   As described above, according to the farm work machine 1, the pair of vibrating bodies 21 vibrate in the left-right direction, and the vibrating bodies 21 vibrate the root portions W <b> 2 entangled with the plurality of crops W being conveyed by the mining conveyor 12. Since the soil adhering to the root W2 is dropped while loosening, not only the adhering soil of the root W2 can be removed properly, but the operator does not need to loosen the root W2 entangled by hand, and the harvesting work can be performed efficiently.

また、振動する振動体21の振動刃部40が掘取コンベヤ12の掘取刃20による掘取に先立って畝Ａを崩すため、掘取コンベヤ12の前方で畝Ａを柔軟にでき、例えば挟持コンベヤ41にて農作物Ｗを適切に挟持でき、よってより一層効率よく収穫作業ができる。   Moreover, since the vibrating blade portion 40 of the vibrating body 21 breaks the ridge A prior to the digging by the digging blade 20 of the digging conveyor 12, the ridge A can be made flexible in front of the digging conveyor 12, for example, pinching The crops W can be appropriately sandwiched by the conveyor 41, so that the harvesting operation can be performed more efficiently.

さらに、振動体21の振れ角度を調節することができるため、土質等の圃場の状態等に適切に対応できる。   Furthermore, since the swing angle of the vibrating body 21 can be adjusted, it is possible to appropriately cope with the state of the field such as soil.

なお、農作業機１は、両振動体21間の離間距離が調節不可能なものには限定されず、例えば図１０に示すように、農作物Ｗの本数に対応できるように、ボルト51およびナット52を用いて両振動体21間の離間距離を調節可能としたものでもよい。この図１０に示す振動体21は、支軸23を中心として回動調節することにより両振動体21間の離間距離が調節可能となっている。なお、図示しないが屈曲部21aの屈曲角度の調節により両振動体21間の離間距離を調節できるようにしてもよい。   The farm work machine 1 is not limited to one in which the distance between the vibrators 21 is not adjustable. For example, as shown in FIG. May be used to adjust the separation distance between the two vibrators 21. The vibrating body 21 shown in FIG. 10 can adjust the distance between the vibrating bodies 21 by adjusting the rotation about the support shaft 23. Although not shown, the distance between the vibrating bodies 21 may be adjusted by adjusting the bending angle of the bending portion 21a.

また、振動体21は、板材にて構成された略細長板状のものには限定されず、例えば図１１に示すように、複数、例えば２本の棒材53にて構成された略細長棒状のもの等でもよく、振動体21の形状は任意である。   Further, the vibrating body 21 is not limited to a substantially elongated plate-shaped member made of a plate material. For example, as shown in FIG. 11, the vibrating body 21 has a substantially elongated rod shape formed of a plurality of, for example, two rod members 53. The shape of the vibrating body 21 is arbitrary.

さらに、振動体21は、回動により左右方向に振動するものには限定されず、例えば平行移動により左右方向に振動するもの等でもよい。また、左右方向に振動する振動体21は、少なくとも左右方向成分を含んだ方向に振動するものであればよい。   Furthermore, the vibrating body 21 is not limited to one that vibrates in the left-right direction by rotation, and may be one that vibrates in the left-right direction by parallel movement, for example. Further, the vibrating body 21 that vibrates in the left-right direction only needs to vibrate in a direction including at least the left-right direction component.
