本発明の農作業機の一実施の形態を図面を参照して説明する。   An embodiment of an agricultural machine according to the present invention will be described with reference to the drawings.

図１および図２において、１は農作業機で、この農作業機１は、例えば走行車であるトラクタ（図示せず）に連結された状態で、トラクタの走行により前方（図示Ｘ方向）に移動しながら圃場の農作物ａの掘取作業を行う掘取機である。   1 and 2, reference numeral 1 denotes an agricultural machine. The agricultural machine 1 is moved forward (in the X direction in the figure) by traveling of the tractor while being connected to a tractor (not shown) as a traveling vehicle, for example. However, it is a digger which performs digging work of the crop a in the field.

なお、掘取対象物である農作物ａは、例えば圃場に複数列状に凸設された畝Ａに栽培された略球状の馬鈴薯（食用部分）である。   In addition, the crop a which is a digging object is, for example, a substantially spherical potato (edible portion) cultivated on a ridge A protruding in a plurality of rows on the field.

農作業機１は、機枠２を備え、この機枠２は前部に３点連結部４を有し、この３点連結部４がトラクタの３点リンク部に連結されている。また、機枠２は前部略中央に図示しない入力軸保持部を有し、この入力軸保持部にてトラクタからの動力を入力する略前後方向の入力軸５が回転可能に保持され、この入力軸５がトラクタのＰＴＯ軸にユニバーサルジョイントおよび伝動シャフト等を介して連結されている。   The agricultural machine 1 includes a machine frame 2, which has a three-point connecting portion 4 at a front portion, and the three-point connecting portion 4 is connected to a three-point link portion of the tractor. In addition, the machine frame 2 has an input shaft holding portion (not shown) in the approximate center of the front portion. The input shaft holding portion rotatably holds the input shaft 5 in the front-rear direction for inputting power from the tractor. The input shaft 5 is connected to the PTO shaft of the tractor via a universal joint and a transmission shaft.

そして、機枠２には、圃場の畝Ａから農作物ａを掘り取って搬送する掘取搬送手段７が設けられ、この掘取搬送手段７は機枠２の左右両側の側板部８間に配設されている。   The machine frame 2 is provided with a digging and conveying means 7 for digging and conveying the crop a from the basket A in the field, and the digging and conveying means 7 is arranged between the side plate portions 8 on both the left and right sides of the machine frame 2. It is installed.

掘取搬送手段７は、例えば農作物ａを掘り取る略板状で前下り傾斜状の掘取刃（先金）９と、この掘取刃９にて掘り取られた農作物ａを受け入れて斜め後上方に向けて載置搬送するロッド式の搬送コンベヤ（ロッドコンベヤ）10とにて構成されている。   The digging and conveying means 7 receives, for example, a substantially plate-shaped forward and downward digging blade (lead) 9 for digging the crop a and the crop a digged by the digging blade 9 obliquely. It is comprised with the rod-type conveyance conveyor (rod conveyor) 10 which mounts and conveys upwards.

搬送コンベヤ10は、入力軸５側からの動力を第１伝動手段（図示せず）を介して受けて駆動回転する駆動回転体11を有し、この駆動回転体11と離間対向して従動回転体12が配設されている。そして、これら駆動回転体11および従動回転体12間には左右一対の無端体13が掛け渡され、両無端体13間には複数本のロッド14が互いに等間隔をおいて並設されている。   The conveyor 10 has a drive rotator 11 that rotates by receiving power from the input shaft 5 side through a first transmission means (not shown), and is driven to rotate opposite to the drive rotator 11. A body 12 is disposed. A pair of left and right endless bodies 13 are spanned between the driving rotating body 11 and the driven rotating body 12, and a plurality of rods 14 are arranged in parallel with each other between the endless bodies 13. .

また、機枠２には、左右方向の回転中心軸線を中心として所定方向に駆動回転しながら農作物ａと雑物ｂとを分離する１つの分離ローラ（雑物処理ローラ）21が設けられ、この分離ローラ21は機枠２の両側板部８の後端部間において掘取搬送手段７の搬送終端部の近傍に配設されている。すなわち、掘取搬送手段７の搬送コンベヤ10の搬送終端部との間の間隙20へ雑物ｂを引き込むようにして搬送コンベヤ10側からの農作物ａと雑物ｂとを分離する分離ローラ21が機枠２の後端部に回転可能に設けられている。この分離ローラ21にて間隙20へ引き込まれる雑物ｂは、雑草および農作物ａ（馬鈴薯）から引き抜かれた茎葉等である。   In addition, the machine frame 2 is provided with one separation roller (miscellaneous treatment roller) 21 that separates the crop a and the miscellaneous b while driving and rotating in a predetermined direction around the rotation center axis in the left-right direction. The separation roller 21 is disposed between the rear end portions of the side plate portions 8 of the machine frame 2 and in the vicinity of the conveyance end portion of the digging conveyance means 7. That is, the separation roller 21 that separates the crop a and the miscellaneous b from the conveyor 10 side so as to draw the miscellaneous b into the gap 20 between the excavating and conveying means 7 and the conveyance end of the conveyor 10. A rear end portion of the machine casing 2 is rotatably provided. The miscellaneous matter b drawn into the gap 20 by the separation roller 21 is weeds, foliage and the like extracted from the crop a (potato).

なお、分離ローラ21の前方には雑物ｂを掻き取るスクレーパ23が配設され、分離ローラ21の後方には分離ローラ21にて分離された農作物ａをその農作物ａの自重で斜め後下方に向けて搬送するくし状で後下り傾斜状のシュート（スクリーン）24が配設されている。   In addition, a scraper 23 for scraping off the foreign matter b is disposed in front of the separation roller 21, and behind the separation roller 21, the crop a separated by the separation roller 21 is obliquely rearward and downward with its own weight. A comb-like chute (screen) 24 that is downwardly and downwardly inclined is provided.

さらに、機枠２には、左右方向の回転中心軸線を中心として所定方向に駆動回転しながら畝Ａに凹溝部Ａ1をこの畝Ａに沿って形成するとともに分離ローラ21にて分離された雑物ｂを畝Ａの凹溝部Ａ1の土中に埋め込む１つの鎮圧ローラ26が設けられ、この鎮圧ローラ26は分離ローラ21の下方、例えば略真下に配設されている。   Further, the machine frame 2 is formed with a groove A1 along the ridge A while being driven and rotated in a predetermined direction around the rotation center axis in the left-right direction, and is separated by the separation roller 21. One pressure-reducing roller 26 for embedding b in the groove A1 of the groove A is provided, and this pressure-reducing roller 26 is disposed below the separation roller 21, for example, substantially directly below.

すなわち、分離ローラ21にて分離され搬送コンベヤ10および分離ローラ21間の間隙20を通って鎮圧前の畝Ａ上に落下した雑物ｂを畝Ａの凹溝部Ａ1の土中に埋め込む鎮圧ローラ26が機枠２の後端部に回転可能に設けられている。   That is, the pressure-reducing roller 26 that embeds the foreign matter b separated on the separation roller 21 and passing through the gap 20 between the conveying conveyor 10 and the separation roller 21 on the reed ridge A before being relieved in the soil of the groove A1 of the reed groove A. Is rotatably provided at the rear end of the machine casing 2.

ここで、鎮圧ローラ26は、図２に示されるように、機枠の左右両側のチェーンケース部27およびブラケット部28間に軸架された左右方向の軸部29を有し、この軸部29に分離ローラ21より外径が大きく外周面が円筒面状のローラ本体部30が軸部29と一体となって駆動回転するように設けられている。   Here, as shown in FIG. 2, the pressure reducing roller 26 has a left and right shaft portion 29 pivoted between the chain case portion 27 and the bracket portion 28 on both the left and right sides of the machine frame. Further, a roller main body 30 having an outer diameter larger than that of the separation roller 21 and a cylindrical outer peripheral surface is provided so as to be driven and rotated integrally with the shaft portion 29.

また、この鎮圧ローラ26のローラ本体部30の軸方向の長さ寸法Ｌは畝Ａの幅寸法より小さくなっており、ローラ本体部30の鎮圧により畝Ａには凹溝部Ａ1が形成される。   The axial length L of the roller main body 30 of the pressure reducing roller 26 is smaller than the width of the flange A, and the concave groove A1 is formed in the flange A by the pressure of the roller main body 30.

そして、分離ローラ21にて雑物ｂと分離された農作物ａは、シュート24上を通った後、鎮圧ローラ26のローラ本体部30にて畝Ａの凹溝部Ａ1の溝底面部の土中に埋め込まれた雑物ｂ上に落下する。また、分離ローラ21にて雑物ｂと分離された農作物ａを畝Ａの凹溝部Ａ1内に向けて誘導する略板状をなす左右一対の誘導体31が機枠２に固設されている。   Then, after the crop a separated from the miscellaneous b by the separation roller 21 passes over the chute 24, it is put into the soil at the bottom of the groove A1 of the ridge A by the roller body 30 of the pressure reducing roller 26. It falls on the embedded miscellaneous object b. Further, a pair of left and right derivatives 31 having a substantially plate shape for guiding the crop a separated from the miscellaneous b by the separation roller 21 into the groove A1 of the ridge A are fixed to the machine frame 2.

なお、鎮圧ローラ26は、機枠２に上下位置調節可能（高さ調節可能）に設けられ、掘取搬送手段７に対して上下位置調節可能となっている。つまり、チェーンケース部27およびブラケット部28は左右方向の支軸33を中心として回動可能であり、チェーンケース部27およびブラケット部28には支持アーム34の一端部が回動可能に取り付けられており、この支持アーム34の他端部は、この他端部に形成された複数の孔部35の中から選択された一の孔部35に装着された固定具36にて機枠２の所定部位に固着されている。そして、固定具36を装着する孔部35の選択により、鎮圧ローラ26の上下位置が調節可能となっている。   The pressure reducing roller 26 is provided on the machine casing 2 so that the vertical position can be adjusted (height can be adjusted), and the vertical position can be adjusted with respect to the digging and conveying means 7. In other words, the chain case portion 27 and the bracket portion 28 can be rotated around the support shaft 33 in the left-right direction, and one end portion of the support arm 34 is rotatably attached to the chain case portion 27 and the bracket portion 28. The other end of the support arm 34 is fixed to the predetermined frame of the machine frame 2 by a fixture 36 attached to one hole 35 selected from the plurality of holes 35 formed at the other end. It is fixed to the site. The vertical position of the pressure reducing roller 26 can be adjusted by selecting the hole 35 in which the fixture 36 is mounted.

また、機枠２の左右両側の下部には、隣合う畝Ａ間の圃場面上を滑走する左右一対のそり体（スキット）41が設けられ、このそり体41は平面視で鎮圧ローラ26の左右両側方に配設されている。   In addition, a pair of left and right sled bodies (skits) 41 that slide on the farm scene between adjacent ridges A are provided at the lower portions of the left and right sides of the machine frame 2. It is arranged on both the left and right sides.

そり体41は、鎮圧ローラ26と同様、機枠２に上下位置調節可能（高さ調節可能）に設けられ、掘取搬送手段７に対して上下位置調節可能となっている。つまり、そり体41は支持アーム42を介して機枠２に設けられ、この支持アーム42の上端部は、この上端部に形成された複数の孔部43の中から選択された一の孔部43に装着された固定具44にて機枠２の所定部位に固着されている。そして、固定具44を装着する孔部43の選択により、そり体41の上下位置が調節可能となっている。   The sled body 41 is provided in the machine frame 2 so that the vertical position can be adjusted (height can be adjusted), and the vertical position can be adjusted with respect to the digging and conveying means 7, as with the pressure reducing roller 26. That is, the sled body 41 is provided in the machine frame 2 via the support arm 42, and the upper end portion of the support arm 42 is one hole portion selected from the plurality of hole portions 43 formed in the upper end portion. It is fixed to a predetermined part of the machine frame 2 with a fixture 44 attached to 43. The vertical position of the sled body 41 can be adjusted by selecting the hole 43 in which the fixture 44 is mounted.

また一方、図３に示すように、分離ローラ21および鎮圧ローラ26には搬送コンベヤ10を駆動する駆動回転体11側からの動力が第２伝動手段46を介して伝達され、分離ローラ21および鎮圧ローラ26が所定方向へ駆動回転するようになっている。   On the other hand, as shown in FIG. 3, the power from the drive rotating body 11 driving the conveying conveyor 10 is transmitted to the separation roller 21 and the pressure reducing roller 26 via the second transmission means 46, and the separation roller 21 and the pressure reducing roller 26 are pressed. The roller 26 is driven to rotate in a predetermined direction.

第２伝動手段46は、分離ローラ21の端部に固着されたスプロケット47と、第１スプロケット48と、第２スプロケット49と、これら３つのスプロケット47，48，49に掛け渡され駆動回転体11のスプロケット50と係合した第１チェーン51とを有している。また、第２伝動手段46は、鎮圧ローラ26の端部に固着されたスプロケット52と、第２スプロケット49にシャフト（図示せず）を介して連結された第３スプロケット53と、これら２つのスプロケット52，53に掛け渡された第２チェーン54とを有している。   The second transmission means 46 is spanned between the sprocket 47 fixed to the end of the separation roller 21, the first sprocket 48, the second sprocket 49, and these three sprockets 47, 48, 49. The first chain 51 is engaged with the sprocket 50. The second transmission means 46 includes a sprocket 52 fixed to the end of the pressure reducing roller 26, a third sprocket 53 connected to the second sprocket 49 via a shaft (not shown), and the two sprockets. And a second chain 54 spanned between 52 and 53.

なお、スプロケット47，48，49，50および第１チェーン51は機枠２の進行方向左側のチェーンケース部56内に配設され、スプロケット52，53および第２チェーン54はチェーンケース部27内に配設されている。第１伝動手段の一部は、機枠２の進行方向右側のチェーンケース部57内に配設されている。   The sprockets 47, 48, 49, 50 and the first chain 51 are disposed in the chain case portion 56 on the left side in the traveling direction of the machine frame 2, and the sprockets 52, 53 and the second chain 54 are disposed in the chain case portion 27. It is arranged. A part of the first transmission means is disposed in the chain case portion 57 on the right side in the traveling direction of the machine casing 2.

次に、上記一実施の形態の動作等を説明する。   Next, the operation and the like of the above embodiment 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（図示Ｘ方向）に移動させると、農作物ａは、茎葉が付いたままの状態で雑草等とともに、掘取刃９にて掘り取られ、搬送コンベヤ10にて斜め後上方へ搬送される。   When the entire farm work machine 1 is moved forward (in the X direction in the figure) by traveling the tractor in a state where it is connected to the tractor, the crop a is dug by the digging blade 9 together with weeds and the like with the foliage attached. And is transported obliquely rearward and upward by the transport conveyor 10.

そして、図４に示すように、雑物ｂである茎葉が付いた農作物ａが搬送コンベヤ10の搬送終端部から搬出されると、雑物ｂは、駆動回転する分離ローラ21にて農作物ａから引き抜かれるようにして分離されて間隙20へ引き込まれ、その後、鎮圧ローラ26の前方側において鎮圧前の畝Ａ上に落下する。   Then, as shown in FIG. 4, when the crop a with the foliage b, which is the miscellaneous substance b, is unloaded from the conveyance end portion of the conveyor 10, the miscellaneous b is separated from the agricultural product a by the separation roller 21 that is driven and rotated. It is separated so as to be pulled out and drawn into the gap 20, and then falls on the heel A before pressure reduction on the front side of the pressure reduction roller 26.

この畝Ａ上に落下した雑物ｂは、図５に示すように、駆動回転する鎮圧ローラ26にて踏まれて畝Ａの凹溝部Ａ1の溝底面部の土中に埋め込まれ、この土中に埋め込まれた雑物ｂ上には分離ローラ21側からの農作物ａつまり例えば略球状の馬鈴薯の食用部分が落下する。   As shown in FIG. 5, the miscellaneous substance b falling on the ridge A is stepped on by a pressure-rotating roller 26 that rotates and is buried in the soil at the bottom surface of the groove A1 of the ridge A. A crop a from the separation roller 21 side, that is, an edible portion of, for example, a substantially spherical potato, falls on the miscellaneous substance b embedded in.

そして、このように上記農作業機１によれば、分離ローラ21にて雑物ｂと分離された農作物ａは、鎮圧ローラ26にてその農作物ａの落下に先立って畝Ａの土中に埋め込まれた雑物ｂ上に落下するため、農作物ａと雑物ｂとが混ざりにくくなり、よって、作業者による手作業である農作物ａの収集作業を容易に行うことができる。   Thus, according to the farm work machine 1, the crop a separated from the miscellaneous material b by the separation roller 21 is embedded in the soil of the basket A prior to the fall of the crop a by the pressure roller 26. Therefore, the crop a and the miscellaneous b are less likely to be mixed with each other, so that it is possible to easily collect the crop a which is a manual operation by the operator.

また、鎮圧ローラ26の左右両側方に配設され隣合う畝Ａ間の圃場面上を滑走する対をなすそり体41を備えるため、農作業機１の自重を鎮圧ローラ26とそり体41とに分散でき、鎮圧ローラの上下位置（高さ位置）の安定化を図ることができる。   In addition, since the pair of sled bodies 41 that are arranged on the left and right sides of the pressure roller 26 and slide on the field between the adjacent ridges A are provided, the weight of the farm work machine 1 is reduced to the pressure roller 26 and the sled body 41. It is possible to disperse and to stabilize the vertical position (height position) of the pressure reducing roller.

さらに、鎮圧ローラ26およびそり体41がいずれも上下位置調節可能となっているため、例えば土質に応じて鎮圧ローラ26の接地圧を設定でき、圃場の状態等に適切に対応できる。   Furthermore, since both the pressure-reducing roller 26 and the sled body 41 can be adjusted in the vertical position, the ground pressure of the pressure-reducing roller 26 can be set according to, for example, the soil quality, and can appropriately cope with the state of the field.

また、対をなす誘導体31にて畝Ａの凹溝部Ａ1内に向けて農作物ａを適切に誘導できるため、農作物ａが隣合う畝Ａ間の圃場面上にこぼれ落ちてちらばることを抑制でき、農作物ａの収集作業のより一層容易化を図ることができる。   Moreover, since the crop a can be appropriately guided by the derivative 31 forming a pair toward the groove A1 of the ridge A, the crop a can be prevented from spilling on the field scene between adjacent ridges A. The collection work of the crop a can be further facilitated.

なお、上記農作業機１では、分離ローラ21および鎮圧ローラ26を強制的に駆動回転させる構成について説明したが、例えば搬送コンベヤ10と分離ローラ21とで挟持された雑物ｂから受ける力で分離ローラ21が回転するようにしてもよく、また圃場の畝Ａから受ける力で鎮圧ローラ26が回転するようにしてもよい。   In the agricultural work machine 1 described above, the configuration in which the separation roller 21 and the pressure reducing roller 26 are forcibly driven and rotated has been described. 21 may be rotated, or the pressure reducing roller 26 may be rotated by a force received from the basket A in the field.

また、鎮圧ローラ26を分離ローラ21の略真下に配設した構成には限定されず、例えば鎮圧ローラ26を分離ローラ21より後方に配設した構成でもよい。   Further, the configuration is not limited to the configuration in which the pressure-reducing roller 26 is disposed almost directly below the separation roller 21. For example, the configuration in which the pressure-reducing roller 26 is disposed behind the separation roller 21 may be employed.

さらに、例えば畝Ａの幅寸法に対応できるように鎮圧ローラ26のローラ本体部30の軸方向の長さ寸法Ｌを調節可能としてもよい。また、ローラ本体部30の長さ寸法Ｌを調節可能とした場合には、その長さ寸法Ｌに対応できるように誘導体31の位置も調節できるようにしてもよい。   Further, for example, the length dimension L in the axial direction of the roller main body 30 of the pressure reducing roller 26 may be adjustable so as to correspond to the width dimension of the flange A. Further, when the length dimension L of the roller main body 30 can be adjusted, the position of the derivative 31 may be adjusted so as to correspond to the length dimension L.

また、鎮圧ローラ26およびそり体41の両方を上下位置調節可能とした構成には限定されず、鎮圧ローラ26およびそり体41のいずれも一方のみを上下位置調節可能とした構成でもよい。   Further, the configuration is such that both the pressure roller 26 and the sled body 41 can be adjusted in the vertical position, and either the pressure roller 26 and the sled body 41 may be configured such that only one of the pressure roller 26 and the sled body 41 can be adjusted in the vertical position.
