The frame 17b is integrally formed in a substantially T shape in a side view.

次に、下揃え装置１８は、図３乃至図５に示すように、挟持搬送装置１３で引抜いた根菜部６ｂを挟持搬送ベルト１４，１４から下方側を揃える（一定にする）装置である。
詳しくは、後上がりに傾斜した一対の挟持搬送ベルト１４、１４を対向して後方回動する挟持搬送装置１３の前端近傍下方に、挟持搬送装置１３の後方上がりの傾斜角Ａより緩やかな傾斜角Ｂを設定した下揃え装置１８を構成している。 Next, as shown in FIGS. 3 to 5, the lower aligning device 18 is a device that aligns (makes constant) the lower side of the root vegetable part 6 b extracted by the sandwiching and transporting device 13 from the sandwiching and transporting belts 14 and 14.
More specifically, an inclination angle that is gentler than an inclination angle A of the rearward raising of the nipping and conveying apparatus 13 below the front end of the nipping and conveying apparatus 13 that rotates backward while facing the pair of nipping and conveying belts 14 and 14 inclined rearwardly upward. A bottom alignment device 18 in which B is set is configured.

下揃え装置１８は、ベルトフレーム１７ｂから下方へ延出した前吊下げ具２０、２０と、挟持搬送ベルト１４、１４背面に巻き掛けした上プーリ２２、２２（軸と上プーリを固着して軸を下方へ延出している）を回動自在に支持した後吊下げ具２１、２１を設け、この吊下げ具２０、２０、２１、２１の下方に、前プーリ２４、２４と後プーリ（軸を後プーリに固着した）２３、２３を回動自在に架設した吊具２５、２５を前吊下げ具２０、２０と後吊下げ具２１、２１に締結部材４７を介して固設している。
そして、前プーリ２４、２４と後プーリ（軸を後プーリに固着した）２３、２３間に左右方向に対向して設けた揃えベルト１９、１９を対向間に隙間を有して巻き掛けしている。
そして、上プーリ２２、２２から下方へ延出した軸と、後プーリ２３、２３から上方へ延出した軸を自在継手２６、２６を介して連動連結して後プーリ２３、２３に回転力を付与している。 The lower alignment device 18 includes front suspension members 20 and 20 extending downward from the belt frame 17b, and upper pulleys 22 and 22 wound around the rear surfaces of the holding and conveying belts 14 and 14 (the shaft and the upper pulley are fixed to each other). The rear suspension tools 21 and 21 that rotatably support the front pulleys 24 and 24 and the rear pulley (shaft) are provided below the suspension tools 20, 20, 21, and 21. The hanger 25, 25, which is rotatably mounted on the rear pulley 23, is fixed to the front hanger 20, 20 and the rear hanger 21, 21 via a fastening member 47. .
Then, the alignment belts 19, 19 provided in the left-right direction between the front pulleys 24, 24 and the rear pulleys (shafts fixed to the rear pulleys) 23, 23 are wound with a gap between them. Yes.
Then, the shaft extending downward from the upper pulleys 22 and 22 and the shaft extending upward from the rear pulleys 23 and 23 are interlocked and connected to each other via the universal joints 26 and 26 so that rotational force is applied to the rear pulleys 23 and 23. Has been granted.

そして、挟持搬送装置１３で葉茎部６ａを挟持した根菜作物６が下揃え搬送装置１８の始端部に達すると、下揃え搬送装置１８で根菜部６ｂの上部を挟持して挟持搬送装置１３とともに引継ぎ搬送する。
このとき、下揃え搬送装置１８の後方に行くほど、挟持搬送装置１３との上下間隔が開くから、このままでは、葉茎部６ａがちぎれてしまう（但し、挟持搬送装置１３の搬送速度と下揃え装置１８の搬送速度を同じに設定してある）。このため、下揃え搬送装置１８の揃えベルト１９、１９の挟持力を、挟持搬送ベルト１４、１４よりも弱くしておき、葉茎部６ａが一対の揃えベルト１９、１９間を上方に滑り移動できるようにしている。
そして、根菜部６ｂは、揃えベルト１９、１９間を通過できないようにしている。従って、揃えベルト１９、１９の搬送中に、根菜部６ｂの肩が揃えベルト１９、１９の下端に擦り付けられるまで上昇する。これにより、根菜部６ｂの肩の高さが揃うようになる。 Then, when the root vegetable crop 6 that has sandwiched the leaf stem portion 6a by the sandwiching and transporting device 13 reaches the start end portion of the lower alignment transporting device 18, the upper part of the root vegetable portion 6b is sandwiched by the lower alignment transporting device 18 together with the sandwiching and transporting device 13 Take over and carry.
At this time, as it goes to the rear of the lower alignment transport device 18, the vertical distance from the sandwiching transport device 13 increases, so that the leaf stem portion 6 a is torn off as it is (however, the transport speed of the sandwiching transport device 13 and the lower alignment are aligned) The conveying speed of the apparatus 18 is set to be the same). For this reason, the clamping force of the alignment belts 19 and 19 of the lower alignment conveying device 18 is made weaker than that of the clamping conveyance belts 14 and 14, and the leaf stem portion 6a slides upward between the pair of alignment belts 19 and 19. I can do it.
And the root vegetable part 6b is made so that it cannot pass between the alignment belts 19 and 19. FIG. Accordingly, the shoulder of the root vegetable portion 6 b rises while being rubbed against the lower ends of the alignment belts 19, 19 during the conveyance of the alignment belts 19, 19. Thereby, the height of the shoulder of the root vegetable part 6b comes to be aligned.

直交泥落し装置２７は、図３乃至図５に示すように、下揃え装置１８の終端部下方に、放射状に形成した回転体２８を、挟持搬送装置１３（下揃え装置１８）の搬送方向に対して直交して配設し、この回転体２８を側面視で時計方向に回転させて根菜部６ｂから伸びた根部６ｃや根菜部６ｂに付着した土壌を落す装置である。 As shown in FIGS. 3 to 5, the orthogonal mud dropping device 27 has a rotating body 28 formed radially below the end of the lower aligning device 18 in the conveying direction of the nipping and conveying device 13 (lower aligning device 18). It is an apparatus that is disposed orthogonally to the rotary body 28 and rotates the rotating body 28 clockwise in a side view to drop the root portion 6c extending from the root vegetable portion 6b and the soil attached to the root vegetable portion 6b.

詳しくは、下揃え装置１８で搬送中の根菜作物６の根部６ｃに付着した土壌を叩き落す回転体２８を、中央ボス部３２から半径方向に複数個（本実施例では３本）突出する突出部３３を設け、これらを、軟質合成樹脂で一体形成し、この回転体２８を駆動する軸に、回転体２８と間座（図示していない）を幾重も組み合わせた回転軸３４に一体構成してい
る。
この回転軸３４を軸支した伝動ケース３１を、回動フレーム１７ａ（図３に示す）の側方から斜め前方へ延出した取付具２９と、伝動ケース３１を側面に固設した取付具３０を締結部材４７を介して下揃え装置１８の下方へ固設している。
そして、取付具２９には、取付具３０を上下調整できるように、取付孔３５、３５を上下に長孔を形成して、取付具３０を上下調整する機能を構成することで、ニンニク大きさ直径で５〜８ｃｍで高さ３〜６ｃｍの大きさであるため、収穫する圃場によって適宜に調整することが可能である。 Specifically, a plurality of rotating bodies 28 that knock down the soil adhering to the root portion 6c of the root vegetable crop 6 being conveyed by the bottom aligning device 18 protrude in a radial direction from the central boss portion 32 (three in this embodiment). A portion 33 is provided, which is integrally formed of a soft synthetic resin, and is integrally formed on a rotating shaft 34 in which the rotating body 28 and spacers (not shown) are combined in multiple layers with a shaft for driving the rotating body 28. ing.
The transmission case 31 that pivotally supports the rotating shaft 34 is attached to a fixture 29 that extends obliquely forward from the side of the rotating frame 17a (shown in FIG. 3), and a fixture 30 that is fixed to the side of the transmission case 31. Is fixed below the lower aligning device 18 via the fastening member 47.
The attachment 29 has a function of vertically adjusting the attachment 30 by forming elongated holes in the attachment holes 35 and 35 so that the attachment 30 can be adjusted up and down. Since it is 5 to 8 cm in diameter and 3 to 6 cm in height, it can be appropriately adjusted depending on the field to be harvested.

上記した構造において、下揃え装置１８で葉茎部６ａを挟持した根菜作物６の根部６ｃが、直交泥落し装置２７の回転体２８が側面視で時計方向に回転しているため、回転体２８が根部６ｃの先端（端根）部から根元方向に向けて土壌を叩き落すので、葉茎部６ａを下揃え装置１８で挟持した状態で、土壌を叩き落しするが、回転体２８の回転方向が時計方向のため根菜部６ｂ側から下揃え装置１８が葉茎部６ａを挟持している側へ押し上げるように作用するために根菜部６ｂが回転体２８で踊らされることがないので傷つき防止が図られる。 In the above-described structure, the root part 6c of the root crop 6 having the leaf stem part 6a sandwiched by the lower aligner 18 rotates the rotating body 28 of the orthogonal mud dropping device 27 in the clockwise direction in a side view.

詳しくは、図３、図５、図１４、図１５に示すように、根整姿装置３７は、回動フレーム１７ａから斜め前方下方へ延出した取付具２９の側面に軸回転ブラシ４２、４２の支持と、ベベルギヤー伝動機構を軸支した駆動ケース３８を挟持搬送装置１３の搬送経路Ｃ（搬送ベルト１４，１４で葉茎部６Ａを挟持して後方搬送する通路）に向けて固設している。
そして、前述した駆動ケース３８に、平面視で挟持搬送装置１３の挟持搬送ベルト１４の下方位置に、搬送経路Ｃを挟んで挟持搬送ベルト１４、１４と略平行に左右一対の第１回転体３９、３９と、その後方に、第２回転体４０、４０を軸４１を挟んで一体構成にした軸回転ブラシ４２、４２を回転自在に設けている。
この、軸回転ブラシ４２、４２の前端部に軟質樹脂等で構成したボス部３２と、ボス部３２から半径方向へ突出する複数の突出部３３を一体構成したブラシと、間座（図示していない）を交互に繰返して重設した第１回転体３９を駆動ケース３８から後方へ延出した軸４１の前端部に一体構成している。
また、軸４１の後端部には、ナイロン毛４４等を植設した第２回転体４０を固設している。
第１回転体３９、３９と第２回転体４０、４０は、各々突出部３３あるいは、ナイロン毛４４が重設するように設けている。（図１４、図１５に示す） Specifically, as shown in FIGS. 3, 5, 14, and 15, the rooting device 37 has shaft rotating brushes 42, 42 on the side surfaces of the fixture 29 that extends obliquely forward and downward from the rotating frame 17 a. And a drive case 38 that pivotally supports a bevel gear transmission mechanism is fixed toward a conveyance path C of the nipping and conveying device 13 (a path for conveying the leaf stem portion 6A between the conveying belts 14 and 14 and conveying it backward). Yes.
Then, a pair of left and right first rotating bodies 39 that are substantially parallel to the nipping and conveying belts 14 and 14 with the conveying path C interposed between the driving case 38 and the above described driving case 38 in a plan view in a lower position of the nipping and conveying belt 14. , 39 and axially rotating brushes 42, 42 in which the second rotating bodies 40, 40 are integrated with the shaft 41 interposed therebetween are rotatably provided at the rear thereof.
The boss part 32 made of soft resin or the like at the front end part of the shaft rotating brushes 42, 42, a brush integrally constituted by a plurality of projecting parts 33 projecting radially from the boss part 32, and a spacer (not shown) The first rotating body 39, which is repeatedly stacked alternately, is integrally configured at the front end portion of the shaft 41 extending rearward from the drive case 38.
A second rotating body 40 in which nylon hair 44 and the like are implanted is fixed to the rear end portion of the shaft 41.
The first rotating body 39, 39 and the second rotating body 40, 40 are provided so that the protruding portion 33 or the nylon bristle 44 overlap each other. (Shown in FIGS. 14 and 15)

そして、駆動ケース３８の出力側には、前述した軸回転ブラシ４２が着脱自在にできる凹凸機構で回転力を伝える凸部（ピン）を設け、この凸部(ピン)に連動連結する軸回転ブラシ４２の前端部には凹部（長孔）を設けている。
軸回転ブラシ４２後端部は、軸回転ブラシ４２を軸架する着脱具４５を設け、この着脱具４５の他方は、茎葉排出フレーム７７から延出した延出部材と締結部材４７を介して着脱自在に構成している。 Further, on the output side of the drive case 38, a convex portion (pin) for transmitting a rotational force is provided by the concave / convex mechanism that allows the axial rotary brush 42 to be detachable, and the axial rotary brush that is interlocked and connected to the convex portion (pin). A concave portion (long hole) is provided in the front end portion of 42.
The rear end portion of the shaft rotating brush 42 is provided with an attaching / detaching tool 45 for pivoting the shaft rotating brush 42, and the other of the attaching / detaching tool 45 is attached / detached via an extending member and a fastening member 47 extending from the foliage discharge frame 77. It is configured freely.

又、第１回転体３９は、一方の突起部３３が搬送経路Ｃを越えて他方の凹陥部に突入する径、芯間距離、位相で配されており、両方の突起部３３で確実に根部６ｃ全体をすごくようになっている。
更に、第２回転体４０のナイロン毛４４等は、互いに相手方の回転半径内に入り込む径、芯間距離に設定されており、両者で根部６ｃを挟み込んですり潰すようになっている。
加えて、両者の回転方向は、根部６ｃを上から下（時計回転方向と反時計方向の組合せ）にすごくように設定されており、これによって、特に、第２回転体４０ですり潰された根部６ｃは根菜部６ｂから大きく広がった根部６ｃを細く絞られ、根部６ｃの先端が先行する姿勢となり、後続する根切り装置８４で切断に都合の良いように整姿されている。
これらのことから、第１回転体３９や第２回転体４０は、軟質樹脂、ゴム、ナイロン毛等といった根菜部６ｂの表面を傷付けない素材で構成されている。 Further, the first rotating body 39 is arranged with a diameter, a distance between the cores, and a phase in which one protrusion 33 enters the other recessed portion beyond the conveyance path C. The whole 6c looks very much like that.
Further, the nylon bristles 44 and the like of the second rotating body 40 are set to have a diameter and a center-to-core distance that enter each other's rotation radius, and the root portion 6c is sandwiched between them so as to be crushed.
In addition, the rotation direction of both is set so as to make the root 6c from top to bottom (a combination of clockwise and counterclockwise directions), and in this way, in particular, the second rotating body 40 is crushed. The root portion 6c is narrowed down from the root portion 6c which is greatly expanded from the root vegetable portion 6b, and the tip of the root portion 6c is in a leading position, and is shaped by the subsequent root cutting device 84 so as to be convenient for cutting.
From these things, the 1st rotary body 39 and the 2nd rotary body 40 are comprised with the material which does not damage the surface of the root vegetables part 6b, such as soft resin, rubber | gum, and nylon hair.

第１回転体３９や第２回転体４０を一体に構成した軸回転ブラシ４２に、上記した作用をさせるには、強制回転させられる必要があるが、本例における駆動構成は、挟持搬送装置１３の姿勢（高さ）を変更してもその位置は不変である回動軸２ｂに設けた動力をプーリ・ベルト機構を介して駆動ケース３８まで導いている。
そして、駆動ケース３８に伝えた動力を、ベベルギヤー伝動機構等によって軸回転ブラシ４２に伝えている。 In order to make the shaft rotating brush 42 integrally configured with the first rotating body 39 and the second rotating body 40 perform the above-described action, it is necessary to forcibly rotate. However, the driving configuration in this example is the nipping and conveying apparatus 13. Even if the posture (height) is changed, the power provided to the rotating shaft 2b whose position remains unchanged is guided to the drive case 38 via the pulley / belt mechanism.
The power transmitted to the drive case 38 is transmitted to the shaft rotating brush 42 by a bevel gear transmission mechanism or the like.

The foliage portion holding and conveying device 61 for discharging backward and the foliage portion narrowing and conveying device for holding the foliage portion 6a holding the foliage portion 6a and discharging the rear portion of the foliage portion 6a above the foliage portion 6a in a posture in which the tip precedes 69 is provided.
Further, an upper aligning device 49 for aligning the height of the root vegetable portion 6 b is provided below the foliage portion holding and conveying device 61 at the lower front end from the foliage portion holding and conveying device 61.
And the root cutting device 84 which cuts the root part 6c extended from the root vegetable part 6b by fixed length is provided in the lower vicinity of the upper alignment apparatus 49, and the foliage cutting device 120 which arranges and cuts the foliage part 6b by fixed length is provided. The discharge shooter 11 is provided behind the upper aligning device 49 and is formed in a bowl shape that discharges the foliage portion 6b cut by the foliage cutting device 120 to the outside of the apparatus.

そして、図６乃至図８に示すように、上揃え搬送装置４９は、挟持搬送装置１３の挟持搬送フレーム１７（ベルトフレーム１７ｂ）から下方に延出した取付部材に保持ベルト５０を巻き掛けする駆動プーリ５４と、従動プーリ５５を吊下げする吊下げ具５３を締結部材４７を介して挟持搬送装置１３の下方に搬送経路Ｃを挟んで左右方向で対向して吊下げしている。
吊り下げ具５３は、一方に、従動プーリ５５を回動自在に吊下げし、他方は、保持ベルト５０を巻き掛けする駆動プーリ５４を軸着した回転軸を軸支した縦ケース５１を立設している。
そして、駆動プーリ５４、５４と従動プーリ５５、５５と間に左右方向に対向して設けた保持ベルト５０、５０を巻き掛けしている。 As shown in FIGS. 6 to 8, the top aligning and conveying device 49 drives the holding belt 50 around the attachment member extending downward from the nipping and conveying frame 17 (belt frame 17 b) of the nipping and conveying device 13. A pulley 54 and a suspending tool 53 for suspending the driven pulley 55 are suspended below the clamping conveyance device 13 via a fastening member 47 so as to face each other across the conveyance path C in the left-right direction.

挟持搬送装置１３で葉茎部６ａを挟持した根菜作物６が上揃え装置４９に到達すると、上揃え装置４９で根菜部６ｂの上方を挟持して挟持搬送装置１３とで引継ぎ後方へ搬送される。
このとき、上揃え装置４９の後方に行くほど、挟持搬送装置１３との上下間隔が開くから、このままでは、葉茎部６ａがちぎれてしまう（但し、挟持搬送装置１３の搬送速度と上揃え装置２１の搬送速度を同じに設定してある）。このため、上揃え装置４９の保持ベルト５０、５０の挟持力を、挟持搬送装置１３の挟持搬送ベルト１４、１４よりも弱くしておき、葉茎部６ａが一対の保持ベルト５０、５０間を上方に滑り移動できるようにしている。
なお、根菜部６ｂは、保持ベルト５０、５０間を通過できないようにしている。従って、保持ベルト５０、５０の搬送中根菜部６ｂの肩が保持ベルト５０、５０の下端に擦り付けられるまで上昇する。
これにより、根菜部６ｂの肩の高さが揃うようになる。 When the root vegetable crop 6 that has sandwiched the leaf stem portion 6a by the sandwiching and conveying device 13 reaches the upper aligning device 49, the upper aligning device 49 sandwiches the upper portion of the root vegetable portion 6b and is transported to the rear side by the sandwiching and conveying device 13. .
At this time, as it goes to the rear of the upper aligning device 49, the vertical distance from the holding and conveying device 13 increases, so that the leaf stem portion 6a is torn in this state (however, the conveying speed of the holding and conveying device 13 and the upper aligning device) 21 is set to the same conveyance speed). Therefore, the holding force of the holding belts 50, 50 of the upper aligning device 49 is made weaker than that of the holding / conveying belts 14, 14 of the holding / conveying device 13, and the leaf stem portion 6a is located between the pair of holding belts 50, 50. It can be slid upward.
The root vegetable portion 6b is prevented from passing between the holding belts 50 and 50. Therefore, the shoulder of the root vegetable portion 6b during conveyance of the holding belts 50, 50 is raised until it is rubbed against the lower ends of the holding belts 50, 50.
Thereby, the height of the shoulder of the root vegetable part 6b comes to be aligned.
