また、搬送部7は、上下回動する搬送終端側と上下回動しない搬送始端側とを搬送方向に2つの異なる無端搬送ベルトを直列配置してそれぞれ周回駆動させる構成とすることもできるが、本例の搬送部7は、上下回動する搬送終端側と上下回動しない搬送始端側とにわたって一つの無端搬送ベルト37cを周回駆動させる構成として、上下回動しない搬送始端側と上下回動する搬送終端側との間の屈曲部をスムーズに根菜類を移動させて搬送できるものとしている。このため、本例においては、搬送部7の搬送ベルト37cを駆動する駆動ローラ37dより上側且つ機体右方側に軸43に取付けた中間ローラ37fを設け、該中間ローラ37fより機体右方側に前記中間ローラ37fの軸43を支点に上下回動可能に支持した回転自在の回転ローラ37eを設け、前記駆動ローラ37dと中間ローラ37fと回転ローラ37eとを内側に囲むようにして単一の無端搬送ベルト37cを巻き掛け、そして、中間ローラ37fの下方を通る搬送ベルト37cの外周に接触する回転自在のテンションローラ37hを設け、搬送部7の搬送作動中における搬送終端側の上下回動範囲を、搬送ベルト37cが中間ローラ37fの個所で搬送終端側が搬送始端側に対して下方に屈曲する状態となるように搬送終端側が下降した位置と、搬送始端側の駆動ローラ37dと中間ローラ37fと搬送終端側の回転ローラ37eとが機体背面視で右上がり傾斜で略直線状に並ぶ状態となるように搬送終端側が上昇した位置との上下範囲内に設定した構成としている。このようにすることで、搬送部7の搬送終端側を下降したときに、搬送ベルト37cが弛んで搬送ベルト37cがスリップするのを防止でき、且つ、搬送部7の搬送終端側を上昇させたときも、その上昇範囲を上記のように設定することで、搬送ベルト37cの上面側に対し根菜類の搬送の妨げになるテンションローラを設けなくても、搬送ベルト37cが弛んで搬送ベルト37cがスリップするのを生じ難くできる。
In addition, the transport unit 7 can be configured so that the transport end side that rotates up and down and the transport start end side that does not rotate up and down are arranged in series in the transport direction and driven in a circular manner, respectively. The transport unit 7 of this example is configured to drive one endless transport belt 37c around the transport terminal end side that rotates up and down and the transport start end side that does not rotate up and down, and rotates up and down with the transport start end side that does not rotate up and down. It is assumed that the root vegetables can be smoothly moved and conveyed at the bent portion between the conveyance end side. Therefore, in this example, an intermediate roller 37f attached to the shaft 43 is provided on the upper side of the drive roller 37d for driving the conveyance belt 37c of the conveyance unit 7 and on the right side of the machine body, and on the right side of the machine body from the intermediate roller 37f. A rotatable roller 37e that is supported rotatably about the shaft 43 of the intermediate roller 37f is provided, and a single endless conveying belt is provided so as to surround the driving roller 37d, the intermediate roller 37f, and the rotating roller 37e. 37c is provided, and a rotatable tension roller 37h that contacts the outer periphery of the conveyor belt 37c passing below the intermediate roller 37f is provided, and the vertical rotation range on the conveyance end side during the conveyance operation of the conveyance unit 7 is conveyed. The conveyance end side is lowered so that the belt 37c is bent downward relative to the conveyance start end side at the position of the intermediate roller 37f. And a position where the conveyance end side is raised so that the drive roller 37d, the intermediate roller 37f, and the rotation roller 37e on the conveyance end side on the conveyance start end side are aligned in a substantially straight line with a right-up inclination when viewed from the rear of the body. The configuration is set within the upper and lower ranges. By doing so, it is possible to prevent the conveyor belt 37c from being loosened and slipping when the conveyor terminal 7 is lowered on the conveyance terminal side, and the conveyance terminal side of the conveyor unit 7 is raised. Even when the ascending range is set as described above, the conveyor belt 37c is loosened and the conveyor belt 37c is moved to the upper surface of the conveyor belt 37c without a tension roller that hinders the conveyance of root vegetables. It is difficult to cause slipping.
また、本例の搬送部7の搬送ベルト37cは、前記のように、平坦な面を有する前後幅広の無端ベルト37aの外周面に周方向に波状に湾曲させて外周側に突出する状態とした可撓性シート37bを周方向設定間隔で貼り付けた構成として、根菜類が斜め上方に持上げ搬送できるようになっている。そして、この波状に湾曲して突出する可撓性シート37bは、前後全幅にわたって設けられていると、上記テンションローラ37hによって折り曲げられてしまうので、テンションローラ37hが接触する中央個所は、可撓性シート37bの突出がないように除いた構成としている。従って、波状に湾曲して突出する可撓性シート37bを設けて持上げ搬送可能とした搬送ベルト37cの構成としながらも、突出する可撓性シート37bを折り曲げないようにして外周面にテンションローラ37hを接触可能にし、搬送ベルト37cを弛ませないで搬送部7を屈曲させることが可能となる。
Further, as described above, the conveyance belt 37c of the conveyance unit 7 of the present example is curved in the circumferential direction in the circumferential direction of the endless belt 37a having a flat front surface and a wide endless belt 37a so as to protrude to the outer circumferential side. As a configuration in which the flexible sheet 37b is pasted at a set interval in the circumferential direction, root vegetables can be lifted and conveyed obliquely upward. If the flexible sheet 37b that curves and protrudes in a wavy shape is provided over the entire front and rear, it is bent by the tension roller 37h, so that the central portion where the tension roller 37h contacts is flexible. The configuration is such that the sheet 37b does not protrude. Accordingly, the tension roller 37h is provided on the outer peripheral surface so as not to bend the projecting flexible sheet 37b while providing the configuration of the conveyor belt 37c that can be lifted and conveyed by providing the flexible sheet 37b that curves and projects in a wave shape. Can be brought into contact with each other, and the conveying portion 7 can be bent without slackening the conveying belt 37c.
回収部6は、収穫部4が配置されている側(左側)とは左右反対側(右側)に配置している。本例では、更に、収穫部4は機体の左側の前部側から後部側にわたって配置し、操縦部3を機体の右側の前部に配置し、そして、回収部6は、操縦部3より機体後側で、且つ、操縦部3より機体左右方向外側で、且つ、搬送部7の機体左右方向外側に配置している。このように回収部6を配置したうえで、前記のように残葉処理部5を機体の右側に向けて根菜類を搬送しながら不要な茎葉部を除去処理して前側に排出する構成とし、搬送部7を、残葉処理部5の前側個所から上記のように配置した回収部6に向けて横方向に搬送する構成としたのである。
The collection unit 6 is arranged on the opposite side (right side) to the side (left side) on which the harvesting unit 4 is arranged. In this example, the harvesting unit 4 is further arranged from the front side on the left side of the aircraft to the rear side, the control unit 3 is arranged on the front side on the right side of the aircraft, and the collection unit 6 It is arranged on the rear side, on the outer side in the left-right direction of the body from the control unit 3 and on the outer side in the left-right direction of the body of the transport unit 7. After arranging the recovery unit 6 in this way, as described above, the remaining leaf processing unit 5 is directed to the right side of the machine body while conveying root vegetables and removing unnecessary foliage and discharging it to the front side. The transport unit 7 is configured to transport in the lateral direction from the front side portion of the remaining leaf processing unit 5 toward the collection unit 6 arranged as described above.
前記特許文献1に記載の根菜類収穫機は、収穫部により収穫され茎葉部を切断されて落下した根菜類を収穫部の後端部から右側方に排出し、継いで、横搬送部で機体右側方に搬送し、更に、縦搬送部で機体前側上方に持上げ搬送して、前記操縦部の後方近傍に配置した前記回収部の収容袋内に放出する構成としている。このため、機体が前後に長い構成となり、圃場端などで機体を旋回するときに幅広い領域を必要として機体の操縦性があまり良くない。また、回収部を操縦部と縦搬送部に前後に挟まれた個所に形成しているので、その回収部に設置できる収容袋の前後幅が回収部の前後幅に制限され、大きい収容袋が使用しにくく作業能率の向上が図りにくい点もある。
The root vegetable harvesting machine described in Patent Document 1 discharges the root vegetables that have been harvested by the harvesting unit, cut off the stem and leaves, and dropped to the right side from the rear end of the harvesting unit, and succeeded by the machine in the horizontal transport unit. It is transported to the right side, further lifted and transported by the longitudinal transport unit to the upper front side of the machine body, and discharged into the storage bag of the collection unit disposed near the rear of the control unit. For this reason, the aircraft has a long configuration in the front-rear direction, and a wide area is required when turning the aircraft at the end of the field, and the maneuverability of the aircraft is not very good. In addition, since the collection unit is formed at a position sandwiched between the control unit and the vertical conveyance unit, the front and rear width of the storage bag that can be installed in the recovery unit is limited to the front and rear width of the recovery unit, It is difficult to use and it is difficult to improve work efficiency.
一方、本例にあっては、収穫した根菜類を収容袋Bに収容する構成とし、且つ、収穫部4により収穫された根菜類に残存する不要な茎葉部を除去する残葉処理部5を備えた根菜類収穫機において、収穫部4により収穫され茎葉部が切断されて落下した根菜類を残葉処理部5によって機体の右側に向けて搬送しながら不要な茎葉部を除去処理して前側に排出する構成とし、そして、搬送部7によって残葉処理部5の前側個所から更に機体の右側に向けて搬送してその搬送終端部の左右方向外側方に配置した回収部6に搬送する構成としたので、残葉処理部5を備え、且つ、従来よりも機体の前後長が短い構成となって、操縦性が良好なものとなり、且つ、回収部6を操縦部3より機体後側で且つ機体左右方向外側に配置したものなので、従来よりも大きな収容袋を設置して一層多くの根菜類を収容することもできて作業能率の向上が図れる。
On the other hand, in this example, the remaining root processing unit 5 is configured to store the harvested root vegetables in the storage bag B and remove unnecessary stems and leaves remaining in the root vegetables harvested by the harvesting unit 4.

本例の根菜類収穫機1は、収穫部4により収穫された根菜類は、機体後部側において左側から右側に根菜類を横方向に搬送する搬送部7によって、機体左側に配置した収穫部4側から左右反対側の機体右側に配置した回収部6に根菜類を搬送する構成としたものであり、しかも、搬送部7の後側近傍個所に該搬送部7で搬送される根菜類の選別作業を行う作業者が搭乗する選別作業者搭乗部41,42設け、搬送部7の前側近傍個所に機体を操縦する操縦者が搭乗する操縦部3を設けた構成とし、機体の右側部(搬送部7の搬送終端部の左右方向外方側で且つ選別作業者搭乗部41,42及び操縦部3の左右方向外方側近傍)で、選別作業者搭乗部41,42の側方個所から操縦部3の側方個所にわたる前後範囲に、搬送部7により搬送されてきた根菜類を受け入れて回収する収容袋Bを設置可能とした回収部6を設けた構成としたものなので、従来よりも機体の前後長が短い構成となって、操縦性が良好なものとなり、また、回収部6に設置する収容袋Bを前後に幅広い大容量のものを設置することが可能で、更に、収容袋Bが、選別作業者搭乗部41,42の側方個所から操縦部3の側方個所にわたる前後範囲にわたって回収部6上に設置されるので、回収部6への収容袋Bの設置作業や取出し作業が選別作業者搭乗部41,42上からも行なえ、収容袋B内に収容された根菜類の均し作業も、選別作業者搭乗部41,42に搭乗した作業者と操縦部3に搭乗した操縦者とが容易に行えて作業性が良好なものとなる。
In the root vegetable harvesting machine 1 of this example, the root vegetables harvested by the harvesting unit 4 are arranged on the left side of the machine body by the transport unit 7 that transports the root vegetables from the left side to the right side on the rear side of the machine body. The root vegetables are transported from the side to the collection unit 6 disposed on the right side of the machine body opposite to the left and right sides, and the root vegetables transported by the transport unit 7 to a location near the rear side of the transport unit 7 are selected. Selection worker boarding parts 41 and 42 on which a worker who performs work is provided, and a control part 3 on which a pilot maneuvering the aircraft boarding is provided at a position near the front side of the conveyance part 7, and the right side part (conveyance) Steering from the lateral side of the sorting operator boarding portions 41, 42 on the outer side of the transfer terminal of the unit 7 in the lateral direction outward side and in the vicinity of the sorting worker boarding portions 41, 42 and the steering portion 3 in the lateral direction outside). It is conveyed by the conveyance unit 7 in the front-rear range over the side part of the unit 3 Because it is configured to have a collection unit 6 that can install a storage bag B that accepts and collects root vegetables, the front and rear length of the fuselage is shorter than before, and the maneuverability is good. In addition, it is possible to install a large-capacity storage bag B installed in the front and rear of the storage bag B installed in the collection unit 6, and the storage bag B is connected to the control unit 3 from the side of the sorting operator boarding units 41 and 42. Since it is installed on the collection unit 6 over the front and rear range over the side portions of the container, the installation and removal operations of the storage bag B to and from the recovery unit 6 can also be performed from above the sorting operator boarding units 41 and 42, The leveling work of the root vegetables accommodated in the operator can be easily performed by the operator who has boarded the sorting operator boarding parts 41 and 42 and the operator who has boarded the control part 3, and the workability is improved.
また、搬送部7が選別作業者搭乗部41,42の前側近傍に配置し且つ操縦部3の後側近傍に配置した構成としているので、選別作業者搭乗部41,42に搭乗した作業者だけでなく、操縦部3に搭乗した操縦者も機体後方を向いて搬送部7で搬送される根菜類を確認することができ、操縦者が機体の操縦に余裕ができれば、機体後方を振り返って搬送部7で搬送される根菜類の選別作業を行なうこともできる。特に、搬送部7の搬送終端側を上方に回動させて高く位置させたときは、操縦部3から搬送部7が一層接近するので根菜類の選別作業を容易に行なえる。更に、選別作業者搭乗部の座席42は機体左右方向の位置で搬送部7の上下回動支点の近傍位置に位置し、操縦部3の座席12は、機体左右方向の位置で、前記選別作業者搭乗部の座席42より搬送部7の搬送終端側寄りに位置し、更に、選別作業者搭乗部の座席42の着座部の高さが低く、操縦部3の座席12の着座部の高さが高く位置するように設けたので、選別作業者搭乗部の座席42に座る作業者は、搬送部7の搬送終端側を上下回動したときの上下動量の少ない搬送部7の上下回動支点となる軸43の近傍位置で搬送部7によって搬送される根菜類の選別作業が容易に行なえ、一方、操縦部3の座席12に座る操縦者は、機体操縦の合間で、搬送部7の搬送終端側を上方回動させて高く位置させたときに搬送部7の搬送終端側を搬送される根菜類の選別作業を容易に行なうことができる。
In addition, since the transport unit 7 is arranged in the vicinity of the front side of the sorting worker boarding units 41 and 42 and in the vicinity of the rear side of the control unit 3, only the operator who has boarded the sorting worker boarding units 41 and 42. In addition, the pilot who has boarded the control unit 3 can also look at the root vegetables transported by the transport unit 7 while facing the rear of the aircraft, and if the operator can afford to control the aircraft, look back at the aircraft and transport it The root vegetables transported by the section 7 can also be selected. In particular, when the conveyance end side of the conveyance unit 7 is rotated upward to be positioned higher, the conveyance unit 7 comes closer from the control unit 3, so that the root vegetables can be easily selected. Further, the seat 42 of the sorting operator boarding portion is positioned in the vicinity of the vertical pivot of the transport unit 7 in the left-right direction of the body, and the seat 12 of the control unit 3 is positioned in the left-right direction of the body. The seat 42 of the operator boarding part is located closer to the transfer terminal side of the transfer part 7, the seating part of the seat 42 of the sorting operator boarding part is lower, and the height of the seating part of the seat 12 of the control part 3 Therefore, the operator who sits on the seat 42 of the sorting worker boarding section can rotate the fulcrum of the transport unit 7 with a small amount of vertical movement when the transport end side of the transport unit 7 is rotated up and down. The root vegetables transported by the transport unit 7 can be easily selected in the vicinity of the shaft 43 to be, while the operator sitting on the seat 12 of the control unit 3 transports the transport unit 7 between maneuvering operations. The transport end side of the transport unit 7 is transported when the end side is rotated upward and positioned higher. Sorting work root crops that are can be easily performed.
なお、回収部6を選別作業者搭乗部41,42の側方個所から操縦部3の側方個所にわたる前後範囲に配置して作業性が良好なものとしながらも、操縦部3の乗降部よりも後側に回収部6が配置され収容袋Bが設置されるように設けることで、操縦部3への操縦者の乗降が収容袋Bに妨げられることもない。また、選別作業者搭乗部の座席42よりも前側に回収部6が配置され収容袋Bが設置されるように設けることで、選別作業者搭乗部41,42への作業者の乗降も収容袋Bに妨げられることがない。
The collection unit 6 is arranged in a front-rear range extending from the side portion of the sorting operator boarding portions 41 and 42 to the side portion of the control unit 3 to improve workability. In addition, since the collection unit 6 is disposed on the rear side and the storage bag B is provided, the storage bag B does not prevent the operator from getting in and out of the control unit 3. Further, by providing the collection unit 6 so that the storage bag B is installed in front of the seat 42 of the sorting worker boarding unit, the operator can get on and off the sorting worker boarding units 41 and 42. B is not disturbed.
また、図11に示すように、搬送終端側が上下回動する搬送部7の後側にあって、選別作業者が搬送終端側が上昇回動して高くなったときに、搬送始端側から搬送終端側に向く姿勢、即ち、右側斜め前方向に向いた姿勢で、或は、右側横方向に向いた姿勢で容易に座って選別作業が行えるように、右向きにした(背凭れを着座部に対して機体左側に移動させた)座席42’を設けても良い。このように座席42’を設けると、特に、搬送部7の搬送終端側が上昇回動して高くなったときの選別作業が行ないやすくなり、また、回収部6の収容袋B内に収容される根菜類の量を確認しやすくなって、搬送部7の搬送終端側の上昇操作と収容袋Bの上側開口部の上昇操作を一層適確に行えるものとなり、選別された不良の根菜類を機体後方に捨てる場合にその動作も行いやすくなる。また、座席42を回動操作容易設けて、横向き姿勢で座る状態(背凭れを着座部に対して機体左側に位置させた状態)と前向き姿勢で座る状態(背凭れを着座部に対して機体後側に位置させた状態)とに容易に切り替えられるようにすれば、搬送部7の搬送終端側が低いときに前向き姿勢で選別作業を容易に行え、且つ、搬送部7の搬送終端側が高いときに横向き姿勢で選別作業を容易に行なえるようになる。なお、選別作業を行う作業者が前向き姿勢で座る座席を残葉処理部5の上方に配置すれば、機体右側に大きな重量がかかる回収部6に対抗して選別作業者の体重を機体の左側寄りにかかるようにすることができて、機体の左右重量バランスの向上が図れる。
Further, as shown in FIG. 11, when the transport end side is on the rear side of the transport unit 7 that rotates up and down, and the sorting operator rises and rises on the transport end side, the transport end side moves from the transport start end side to the transport end point. To the side, that is, the right side diagonally forward, or the right side to the right side so that it can be easily seated and selected (right back to the seat). It is also possible to provide a seat 42 'that is moved to the left side of the machine body. When the seat 42 ′ is provided in this way, it becomes easy to perform a sorting operation especially when the conveyance end side of the conveyance unit 7 is raised and rotated and becomes high, and is accommodated in the accommodation bag B of the collection unit 6. It becomes easier to check the amount of root vegetables, and it is possible to perform the raising operation on the conveyance end side of the conveyance unit 7 and the raising operation of the upper opening of the storage bag B more accurately. When throwing backward, it becomes easy to perform the operation. In addition, the seat 42 can be easily rotated, and sits in a sideways posture (with the backrest positioned on the left side of the aircraft with respect to the seating portion) and sits in a forward-facing posture (with the backrest against the seating portion. When the transfer end side of the transfer unit 7 is low, the sorting operation can be easily performed in a forward posture and the transfer end side of the transfer unit 7 is high. In addition, the sorting operation can be easily performed in the horizontal orientation. If the seat on which the worker performing the sorting operation sits in a forward-facing posture is disposed above the remaining leaf processing unit 5, the weight of the sorting worker is set to the left side of the aircraft against the collection unit 6 that requires a large weight on the right side of the aircraft. It can be applied to the side and the weight balance of the aircraft can be improved.
また、回収部6には、搬送部7によって搬送されてきた根菜類を内側に収容した収容袋Bの底部を支持する支持台39と、該支持台39上に設置した収容袋Bの上部開口部を広げた状態で支持する収容袋開口部支持手段40を設けている。この支持台39上に支持された収容袋Bは、機体前後方向及び右外側方向に対して広く開放された状態となるので、支持台39上に設置できる収容袋Bの大きさは支持台39上からある程度はみ出るような大きな収容袋でも設置可能であり、また、この支持台39上に設置した収容袋Bは、根菜類を収容して機体の前後方向及び左右外側方向に比較的大きく膨らみながら根菜類を収容することもできる。よって、大きな収容袋Bを設置してその収容袋Bに多くの根菜類を収容して収穫作業を行なうことができ、作業能率の向上を図ることができる。
The collection unit 6 includes a support base 39 that supports the bottom of the storage bag B that stores the root vegetables transported by the transport unit 7, and an upper opening of the storage bag B that is installed on the support base 39. A storage bag opening support means 40 is provided for supporting the part in an expanded state. Since the storage bag B supported on the support base 39 is in a state of being widely opened in the front-rear direction and the right outside direction, the size of the storage bag B that can be installed on the support base 39 is A large storage bag that protrudes to some extent from above can be installed, and the storage bag B installed on the support base 39 stores root vegetables and swells relatively large in the front-rear direction and the left-right outer direction. It can also contain root vegetables. Therefore, a large storage bag B can be installed, and a lot of root vegetables can be stored in the storage bag B to perform a harvesting operation, thereby improving work efficiency.
本例の根菜類収穫機1は、機体を自走させる走行装置2と、搭乗した操縦者が機体の操縦を行なう操縦部3と、根菜類を圃場から引抜き搬送し茎葉部を切断して根菜類の根部側を収穫する収穫部4と、収穫した根菜類を収容する収容袋Bを設置する回収部6と、前記収穫部4から根菜類を受け取って前記回収部6に搬送する搬送手段5,7を設けた構成とし、更に、前記搬送部7の搬送終端部と、前記回収部6に設置した収容袋Bの上部開口部を広げた状態で支持する収容袋開口部支持手段40を上下同じ方向に昇降可能に設けた構成としている。
The root vegetable harvesting machine 1 of this example includes a traveling device 2 for self-propelling the aircraft, a maneuvering unit 3 for a piloted operator to steer the aircraft, and extracting and transporting root vegetables from the field, cutting the stems and leaves, and cutting roots. A harvesting section 4 for harvesting the root part of the plant, a collection part 6 for installing a storage bag B for accommodating the harvested root vegetables, and a transport means 5 for receiving root vegetables from the harvesting part 4 and transporting them to the collection part 6 , 7, and the upper and lower storage bag opening support means 40 for supporting the transfer terminal 7 of the transfer unit 7 and the upper opening of the storage bag B installed in the recovery unit 6 in an expanded state. It is the structure provided so that raising / lowering was possible in the same direction.
これにより、空の状態の収容袋Bに根菜類を収容し始めるときは、搬送部7の搬送終端部と収容袋開口部支持手段40とを共に低い位置に下降しておけば、根菜類が収容袋B内に落下する距離を小さくでき、また、根菜類の収容量が次第に増えていくに従い、搬送部7の搬送終端部と収容袋開口部支持手段40とをともに上昇させていけば、収容袋Bから根菜類が溢れ出ないようにしながら満杯状態になるまで収容袋Bに根菜類を収容することができる。前記特許文献1に記載される根菜類収穫機では、根菜類が収容袋内に落下する距離を小さくしつつ、根菜類の収容量が増加しても収容袋から根菜類が溢れ出ないで満杯状態になるまで収容袋内に根菜類を収容することができるようにするため、収容袋の底部を支持する支持台を昇降する構成としている。このような構成とすると、大きな荷重がかかる支持台を昇降するため昇降機構を頑丈で強力なものとしなければならず、昇降機構の大型化し、コストアップする問題がある。しかし、上記のように、本例では、収容袋Bの底部を支持する支持台39は昇降しないで、収容袋Bの上部開口部を支持する収容袋開口部支持手段40と搬送部7の搬送終端部とを昇降する構成なので、前記特許文献1に記載される根菜類収穫機のように頑丈で強力な昇降機構は必要とせず、機構の簡略化が図れる効果がある。また、本例では、収容袋開口部支持手段40を搬送部7の搬送終端部に取付け、搬送部7の搬送終端部を収容袋開口部支持手段40とともに昇降する構成としているので、一層、機構の簡略化が図れるものである。
As a result, when the root vegetables are started to be stored in the empty storage bag B, the root vegetables can be moved by lowering both the transport terminal end of the transport unit 7 and the storage bag opening support means 40 to a low position. If the distance dropped into the storage bag B can be reduced, and the storage amount of root vegetables gradually increases, if the transport terminal end of the transport unit 7 and the storage bag opening support means 40 are raised together, The root vegetables can be stored in the storage bag B until the root bag is full while preventing the root vegetables from overflowing from the storage bag B. In the root vegetable harvesting machine described in the above-mentioned Patent Document 1, the root vegetables are filled without causing the root vegetables to overflow even if the amount of root vegetables increases, while reducing the distance that the root vegetables fall into the storage bag. In order to allow root vegetables to be stored in the storage bag until the state is reached, the support base that supports the bottom of the storage bag is raised and lowered. With such a configuration, the elevating mechanism must be made strong and strong in order to elevate and lower the support base to which a large load is applied, and there is a problem that the elevating mechanism becomes large and costs increase. However, as described above, in this example, the support 39 that supports the bottom of the storage bag B does not move up and down, and the transport of the storage bag opening support means 40 that supports the upper opening of the storage bag B and the transport unit 7 is carried out. Since it is the structure which raises / lowers the termination | terminus part, the strong and strong raising / lowering mechanism like the root vegetable harvesting machine described in the said patent document 1 is not required, and there exists an effect which can aim at simplification of a mechanism. Moreover, in this example, since the accommodation bag opening part support means 40 is attached to the conveyance termination part of the conveyance part 7, and it is set as the structure which raises / lowers the conveyance termination part of the conveyance part 7 with the accommodation bag opening part support means 40, the mechanism further Can be simplified.
また、前記特許文献1に記載の根菜類収穫機は、収穫部で収穫した根菜類を、選別コンベアにて収穫部を配置した側から回収部を配置した側に向けて横方向に搬送し、そして、持ち上げコンベアで前方上方に搬送して運転部後方に配置した回収部で根菜類を回収する構成としていて、選別コンベアと回収部の間に別のコンベア(持上げコンベア)があり、機体全体の構成が複雑になり、また、機体重量が増大する欠点がある。
In addition, the root vegetable harvesting machine described in Patent Document 1 conveys the root vegetables harvested in the harvesting section in the horizontal direction from the side where the harvesting section is arranged on the sorting conveyor toward the side where the collection section is arranged, And it is set as the structure which collects root vegetables in the collection part arranged at the front upper part by the lifting conveyor and arranged behind the operation part, and there is another conveyor (lifting conveyor) between the sorting conveyor and the collection part. There are disadvantages that the configuration is complicated and the weight of the airframe is increased.
一方、本例にあっては、上記搬送部7の機体後方側に作業者が搭乗可能とするためのステップ41或は座席42を設けて上記搬送部7で搬送される根菜類に対して選別作業が行えるように構成し、そして、この搬送部7の搬送終端部と収容袋開口部支持手段40とを昇降可能に構成したので、根菜類が収容袋内に落下するときにできるだけ落下距離を小さくして根菜類が痛まないようにするための機構の簡略化が図れ、しかも、選別作業を行う搬送部と回収部の間に別の搬送部を設けずに、選別作業を行う搬送部の搬送終端部から直接回収部へ根菜類が放出されるので、機体全体の構成が簡略になり、また、機体の軽量化が図れる効果がある。
On the other hand, in this example, a step 41 or a seat 42 is provided on the rear side of the body of the transport unit 7 so that an operator can board, and the root vegetables transported by the transport unit 7 are selected. Since it is configured so that the work can be performed, and the transfer terminal portion of the transfer unit 7 and the storage bag opening support means 40 are configured to be movable up and down, the drop distance can be reduced as much as possible when the root vegetables fall into the storage bag. It is possible to simplify the mechanism to prevent the root vegetables from being damaged by reducing the size, and without providing a separate transport unit between the transport unit for performing the sorting operation and the collection unit, the transport unit for performing the sorting operation. Since root vegetables are directly discharged from the conveyance end portion to the collection unit, the configuration of the entire body is simplified, and the weight of the body can be reduced.
上記搬送部7は、搬送始端部と搬送終端部の間に設けた軸43回りに搬送終端側を上下回動可能に設けている。よって、搬送部7の後側に位置する作業者が搬送部7で搬送される根菜類の選別作業を行うとき、搬送部7の全体が上下動せず、搬送部7の搬送途中個所で折れ曲がるようにして搬送終端側が上下回動するので、作業者は搬送部7において上下動の少ない個所で根菜類の選別作業を行うことができ、よって、選別作業を行う個所の搬送部7が低すぎたり高すぎたりすることがなく、搬送終端側を上下可能に構成した搬送部7で搬送される根菜類の選別作業を容易に行うことができる。
The transfer unit 7 is provided with a transfer end side that can be turned up and down around a shaft 43 provided between the transfer start end portion and the transfer end portion. Therefore, when the worker located on the rear side of the transport unit 7 performs the sorting operation of the root vegetables transported by the transport unit 7, the entire transport unit 7 does not move up and down and bends at a point in the middle of the transport of the transport unit 7. Thus, since the conveyance end side is rotated up and down, the operator can perform the root vegetable sorting operation at the portion where the vertical movement is small in the conveyance portion 7, and the conveyance portion 7 at the location where the sorting operation is performed is too low. It is possible to easily select root vegetables to be transported by the transport unit 7 configured so that the transport end side can be moved up and down.
また、搬送部7の搬送終端側の上下回動支点となる軸43を、搬送部7の搬送方向中央位置より搬送始端側寄りに配置すると、搬送終端側を設定高さ上昇させたときの搬送部7の傾斜角を小さくでき、よって、座席42に座る作業者が行う選別作業を行う個所の搬送部7の角度変化が小さくなって選別作業の作業性が良好になる。また、上記の軸43を、選別作業を行う作業者が座る座席42の前側或いはその近傍に位置するように配置することで、搬送部7をその搬送終端側が上下動するよう回動させたとき、搬送部7の座席42の前側個所の上下動量はできるだけ小さくできて、搬送部7を上下回動しても座席42に座る作業者が行う選別作業の作業性が良好になる。更に、上記の軸43を座席42の前側位置にあって搬送終端側に寄せて配置すれば、搬送終端側を設定高さ上昇させたときの搬送部7の傾斜角を小さくでき、座席42に座る作業者が行う選別作業の作業性は一層良好になる。また、上記の軸43を座席42の前側位置にあって座席42の着座部上面より上方に位置するように配置することで、座席42に座る作業者にとって選別作業を行う個所の搬送部7が適度な高さに位置することになって選別作業が容易に行える。
In addition, when the shaft 43 serving as the vertical rotation fulcrum on the conveyance end side of the conveyance unit 7 is arranged closer to the conveyance start end side than the central position in the conveyance direction of the conveyance unit 7, the conveyance when the conveyance end side is raised by a set height The inclination angle of the section 7 can be reduced, and therefore the change in the angle of the transport section 7 at the place where the worker sitting on the seat 42 performs the sorting work is reduced, and the workability of the sorting work is improved. In addition, when the shaft 43 is disposed so as to be positioned in front of or in the vicinity of the seat 42 on which the worker performing the sorting operation sits, the transport unit 7 is rotated so that the transport end side moves up and down. The vertical movement amount of the front portion of the seat 42 of the transport unit 7 can be made as small as possible, and the workability of the sorting work performed by the operator sitting on the seat 42 is improved even if the transport unit 7 is rotated up and down. Furthermore, if the shaft 43 is positioned at the front side of the seat 42 and close to the conveyance end side, the inclination angle of the conveyance unit 7 when the conveyance end side is raised to the set height can be reduced, and the seat 42 The workability of the sorting work performed by the sitting worker is further improved. In addition, by arranging the shaft 43 so as to be positioned in front of the seat 42 and above the upper surface of the seating portion of the seat 42, the transport unit 7 that performs a sorting operation for the worker sitting on the seat 42 can be provided. Since it is positioned at an appropriate height, the sorting operation can be easily performed.
また、上記搬送部7は、軸心が前後方向の軸43回りに搬送終端側が上下動するよう回動可能に設け、且つ、その軸43を残葉処理部5の残葉処理ローラ38の前端部より搬送部7の搬送方向下手側(機体の右側)に位置するように配置し、残葉処理ローラ38の前端部より搬送部7の搬送方向上手側(機体の左側)における搬送部7の上面(搬送面)は残葉処理ローラ38の前端部より下側に位置するように設けている。従って、搬送部7の搬送終端側が、残葉処理ローラ38の前端部より搬送部7の搬送方向下手側に配置した軸43回りに上下動して、残葉処理部5の残葉処理ローラ38の前端部から機体前方側に排出される根菜類を受ける搬送部7の搬送始端側は上下動しないので、残葉処理部5から搬送部7への根菜類の引継ぎが良好に行なわれる。また、残葉処理部5から搬送部7の搬送始端側に供給される根菜類の量が搬送部7の根菜類の搬送量より多くなると、搬送部7の搬送始端側において一時的に根菜類が貯留されることになるが、前記のように搬送部7の搬送終端側が上下動しても、残葉処理部5の残葉処理ローラ38の前端部から機体前方側に排出される根菜類を受ける搬送部7の搬送始端側は上下動しないので、搬送部7の搬送始端側における根菜類の一時的な貯留量は変動しないので、根菜類の収穫量が一時的に増大して搬送部7の搬送始端側で根菜類が溢れるようなことはなく、収穫作業を適正な状態で能率良く行なえる。
Further, the transport unit 7 is provided so as to be pivotable so that the transport end side moves up and down around the shaft 43 in the front-rear direction, and the shaft 43 is provided at the front end of the remaining leaf processing roller 38 of the remaining leaf processing unit 5. Of the transport unit 7 on the upper side of the transport unit 7 in the transport direction (left side of the machine body) from the front end of the remaining leaf processing roller 38. The upper surface (conveying surface) is provided so as to be located below the front end portion of the remaining leaf processing roller 38. Accordingly, the conveyance terminal end side of the conveyance unit 7 moves up and down around the shaft 43 disposed on the lower side in the conveyance direction of the conveyance unit 7 from the front end portion of the residual leaf processing roller 38, and the residual leaf processing roller 38 of the residual leaf processing unit 5. Since the conveyance start end side of the conveyance unit 7 that receives the root vegetables discharged from the front end of the machine to the front side of the machine body does not move up and down, the root vegetables are successfully transferred from the remaining leaf processing unit 5 to the conveyance unit 7. Further, when the amount of root vegetables supplied from the remaining leaf processing unit 5 to the conveyance start end side of the conveyance unit 7 becomes larger than the conveyance amount of root vegetables of the conveyance unit 7, the root vegetables are temporarily stored on the conveyance start end side of the conveyance unit 7. However, even if the conveyance end side of the conveyance unit 7 moves up and down as described above, the root vegetables discharged from the front end of the remaining leaf processing roller 38 of the remaining leaf processing unit 5 to the front side of the machine body Since the transport start end side of the transport unit 7 that receives is not moved up and down, the temporary storage amount of root vegetables on the transport start end side of the transport unit 7 does not fluctuate, so the harvest amount of root vegetables increases temporarily and the transport unit Root vegetables are not overflowing at the conveyance start end side of 7, and the harvesting operation can be performed efficiently in an appropriate state.
搬送部7の搬送終端側を前記軸43回り上下回動する構成とし、更に、搬送部7の搬送終端部に収容袋開口部支持手段40を取付けた構成とすると、前記のように、搬送部7の搬送終端部を収容袋開口部支持手段40とともに昇降できるので、根菜類が収容袋内に落下するときにできるだけ落下距離を小さくして根菜類が痛まないようにするための機構の簡略化が一層図れるものとなり、そのうえ、搬送部7の搬送終端部を前記軸43より下側まで下降可能にし且つ前記軸43より上側まで上昇可能とするように、搬送部7の搬送終端部の昇降範囲を設定すると、搬送部7の搬送終端側の上下回動による収容袋開口部支持手段40の左右方向への移動量を少なくできて、根菜類を収容した収容袋Bが左右に大きく乱れた姿勢とならないようにして根菜類を収容袋Bに収容させることができる。なお、搬送部7の搬送終端部の前記軸43より下側への下降量と、前記軸43より上側への上昇量とを略同じに設定すれば、一層好ましいものとなる。また、搬送部7の搬送終端部の前記軸43より上側への上昇量を、前記軸43より下側への下降量より大きく設定すれば、上下幅の大きい収容袋Bに対して根菜類を多く収容させることができ、作業能率の一層の向上が図れる。
When the conveyance terminal side of the conveyance unit 7 is configured to rotate up and down around the axis 43, and further, the container bag opening support means 40 is attached to the conveyance terminal unit of the conveyance unit 7, the conveyance unit as described above. 7 can be moved up and down together with the storage bag opening support means 40, so that when the root vegetables fall into the storage bag, the dropping distance is made as small as possible so that the root vegetables do not hurt. In addition, the lift end range of the transport end portion of the transport portion 7 can be lowered below the shaft 43 and can be lifted above the shaft 43. Is set, the amount of movement of the accommodation bag opening support means 40 in the left-right direction by the vertical rotation of the conveyance end 7 on the conveyance end side can be reduced, and the accommodation bag B containing the root vegetables is greatly disturbed left and right Not to become It can be accommodated in the bag B the root vegetables Te. It should be noted that it is more preferable to set the amount of lowering of the conveying end portion of the conveying unit 7 downward from the shaft 43 and the amount of upward raising of the shaft 43 to be substantially the same. Moreover, if the amount by which the conveying end portion of the conveying unit 7 is moved upward from the shaft 43 is set to be larger than the amount by which the conveying end 7 is moved downward from the shaft 43, root vegetables can be added to the storage bag B having a large vertical width. A large amount can be accommodated, and the work efficiency can be further improved.
本例の収容袋開口部支持手段40は、収容袋Bの上側開口部の左右前後の四箇所を支持する前後の内側支持部40a,40aと前後の外側支持部40b,40bを備えていて、上側開口部を広く開放した状態で支持できて、搬送部7の搬送終端側から放出される根菜類を適確に収容袋B内に収容させることができる。また、搬送部7の搬送終端部下方個所の収容袋Bの上側開口部を支持する中間支持部40cを設けているので、搬送部7の搬送終端部下方個所の収容袋Bの上側開口部が弛んで搬送部7の搬送終端側から放出される根菜類が収容袋Bの外側にこぼれ落ちることがなく、根菜類を一層適確に収容袋B内に収容させることができる。また、収容袋Bの上側開口部にあって搬送部7の搬送終端側の左右方向内側個所を支持する内側支持部40a,40a及び中間支持部40cは、搬送部7の搬送終端側の上下回動とともに上下回動する搬送部7の搬送終端側のフレーム(具体的には、回動ローラ37eを回動自在に支持している前後の搬送部上下回動側板)に取付けているので、搬送部7の搬送終端側の上下回動とともに、搬送部7の搬送終端側の収容袋Bの上側開口部を支持する内側支持部40a,40a及び中間支持部40cが上下回動して、搬送部7の搬送終端側個所の収容袋Bの上側開口部が搬送部7の搬送終端部から離れることなく確実に支持され、根菜類が収容袋Bの外側にこぼれ落ちることがなく、根菜類を一層適確に収容袋B内に収容させることができる。
The storage bag opening portion support means 40 of this example includes front and rear inner support portions 40a and 40a and front and rear outer support portions 40b and 40b that support the left and right and front and rear four portions of the upper opening of the storage bag B. The upper opening can be supported in a widely open state, and the root vegetables released from the conveyance end side of the conveyance unit 7 can be accurately accommodated in the accommodation bag B. Moreover, since the intermediate support part 40c which supports the upper opening part of the accommodation bag B below the conveyance termination part of the conveyance part 7 is provided, the upper opening part of the accommodation bag B below the conveyance termination part of the conveyance part 7 The root vegetables released from the conveyance end side of the conveyance unit 7 are not spilled out to the outside of the storage bag B, and the root vegetables can be stored in the storage bag B more appropriately. Further, the inner support portions 40a and 40a and the intermediate support portion 40c, which are located in the upper opening of the storage bag B and support the inner side portion in the left-right direction on the transfer end side of the transfer portion 7, are arranged in the vertical direction on the transfer end side of the transfer portion 7. Since it is attached to the frame on the conveyance end side of the conveyance unit 7 that rotates up and down with movement (specifically, the conveyance unit vertical rotation side plate before and after the rotation roller 37e is rotatably supported) The inner support portions 40a and 40a and the intermediate support portion 40c that support the upper opening of the storage bag B on the conveyance end side of the conveyance portion 7 are vertically rotated along with the vertical rotation on the conveyance termination side of the portion 7, and the conveyance portion The upper opening of the storage bag B at the transfer end portion 7 is securely supported without leaving the transfer end portion of the transfer unit 7, and the root vegetables are not spilled outside the storage bag B, so that It can be accommodated in the accommodation bag B accurately.
なお、本例では、内側支持部40a,40a、外側支持部40b,40b、中間支持部40cのそれぞれは、収容袋Bの上側開口部に設けた孔或は輪に引掛けるようにフック状に形成しており、この内側支持部40aと外側支持部40bを左右両端部に形成したハンガー40dを前後に二つ設けて、この前後のハンガー40d,40dの左右中間部に形成した係合部を、前後方向にのびるハンガー支持フレーム40eの前後両端部に係合させ、そして、そのハンガー支持フレーム40eの前後両端部を、搬送部7の搬送終端側のフレーム部(具体的には、前後の前記搬送部上下回動側板)に取付けて搬送部7の搬送終端部の前後両側部から左右方向外方側にのび且つ前後に間隔を広げながらのびる前後の取付アーム40f,40fの各先端部に連結して、各支持部40a,40a;40b,40b;40cを、上下回動する搬送部7の搬送終端側のフレーム部に支持させている。前後のハンガー40d,40dは、ハンガー支持フレーム40eの前後両端部に前後方向軸まわりに回動自在に係合しているので、搬送部7の搬送終端側が上下回動して取付アーム40f,40fが上下回動しても略水平姿勢を維持しながら上下することができるので、収容袋Bの上側開口部を適確に上昇させていくことができて根菜類を収容した収容袋Bの姿勢が大きく乱れることがなく、根菜類を満杯になるまで収容袋Bに適確に収容させることができる。なお、搬送部7の搬送終端部の外側方で搬送部7の搬送終端部より前側から後側にかけて機体平面視前後方向にのびるハンガー支持フレーム40eは、ハンガー40d,40dと連結する前後両端部の間が上方に位置するように上側に屈曲させた形状にしているので、特に、搬送部7の搬送終端側を低い位置に下降させたときに搬送部7の搬送終端部から放出された根菜類がハンガー支持フレーム40eに当たらないようにしている。
In this example, each of the inner support portions 40a and 40a, the outer support portions 40b and 40b, and the intermediate support portion 40c is hooked so as to be hooked on a hole or ring provided in the upper opening of the containing bag B. Two hangers 40d formed with the inner support portion 40a and the outer support portion 40b at the left and right end portions are provided on the front and rear sides, and engagement portions formed at the left and right intermediate portions of the front and rear hangers 40d and 40d are provided. The front and rear end portions of the hanger support frame 40e extending in the front-rear direction are engaged with the front and rear end portions of the hanger support frame 40e. Front and rear mounting arms 40f and 40f extending from the front and rear side portions of the transport end portion of the transport unit 7 to the left and right sides and extending in the front-rear direction. Linked to, the supporting portions 40a, 40a; and the 40c, is supported on the frame portion of the transfer terminal end side of the conveyor 7 up and down rotation; 40b, 40b. The front and rear hangers 40d and 40d are engaged with the front and rear end portions of the hanger support frame 40e so as to be rotatable about the front and rear direction axis, so that the conveyance end side of the conveyance unit 7 is pivoted up and down to attach arm 40f and 40f. Can be moved up and down while maintaining a substantially horizontal posture even if the bag is rotated up and down, the upper opening of the storage bag B can be properly raised, and the posture of the storage bag B containing root vegetables Can be properly stored in the storage bag B until the root vegetables are full. A hanger support frame 40e extending from the front side to the rear side of the transport unit 7 on the outer side of the transport terminal part of the transport unit 7 in the front-rear direction of the machine body in plan view is provided at both front and rear ends connected to the hangers 40d and 40d. Since the shape is bent upward so that the gap is located at the upper side, root vegetables released from the conveyance end portion of the conveyance portion 7 particularly when the conveyance termination side of the conveyance portion 7 is lowered to a low position Does not hit the hanger support frame 40e.
なお、図10〜11に示すような収容袋開口部支持手段40’とすることもできる。即ち、搬送部7の搬送終端側のフレーム(具体的には、前後の前記搬送部上下回動側板)から前後にのびる内側取付軸40gの前後両端部及び前後中間部に前後の内側支持部40a,40aと中間支持部40cを取付け、搬送部7の搬送終端側のフレーム部(具体的には、前後の前記搬送部上下回動側板)に取付けて搬送部7の搬送終端部の前後両側部から略平行状態で搬送部7の搬送終端部から左右方向外方側にのびる前後の取付アーム40h,40hの各先端部に連結した前後にのびる外側取付軸40iの前後両端部に前後の外側支持部40b,40bを取付ける。このように収容袋開口部支持手段40’を構成すると、後側の内側支持部と40aと外側支持部40bとの左右間に取付け部材が配置されず、後側に開放された状態になっているので、搬送部7の後側に位置する作業者が収容袋B内に収容された根菜類を平らに均すために収容袋B内に手を入れて作業を行うときに、収容袋開口部支持手段の取付部材などが邪魔にならず作業がし易くなる。なお、取付アーム40h,40hを板ばね材などによる弾性変形可能な部材で構成すると、収容袋Bを一層バランス良く支持することができる。
In addition, it can also be set as the accommodation bag opening part support means 40 'as shown in FIGS. That is, the front and rear inner support portions 40a are arranged at both front and rear end portions and front and rear intermediate portions of the inner mounting shaft 40g extending front and rear from a frame on the transport end side of the transport portion 7 (specifically, the front and rear transport portion vertical rotation side plates). , 40a and the intermediate support portion 40c are attached to the frame portion on the conveyance end side of the conveyance portion 7 (specifically, the front and rear conveyance portion vertical rotation side plates) and the front and rear side portions of the conveyance end portion of the conveyance portion 7 The front and rear outer support shafts 40i are connected to the front and rear end portions of the front and rear mounting arms 40h and 40h extending from the transport terminal end of the transport section 7 in the substantially parallel state to the front and rear ends. The parts 40b and 40b are attached. When the accommodation bag opening support means 40 ′ is configured in this manner, the attachment member is not disposed between the left and right sides of the rear inner support 40a and the outer support 40b, and is opened to the rear. Therefore, when the worker located on the rear side of the transport unit 7 puts his hand in the storage bag B to work out the root vegetables stored in the storage bag B, the storage bag is opened. The attachment member of the part support means does not get in the way and the operation becomes easy. If the mounting arms 40h, 40h are made of a member that can be elastically deformed by a leaf spring material or the like, the containing bag B can be supported in a more balanced manner.
また、搬送部7の搬送終端部は収容袋開口部支持手段40,40’に支持された収容袋Bの上側開口部内の上方に張り出した状態に位置していて、搬送部7の搬送終端部から放出した根菜類が適確に収容袋B内に収容されるようになっている。また、搬送部7の搬送終端部は、収容袋Bの上側開口部の機体内側個所寄りに位置しているので、搬送部7の搬送終端部から左右方向外側に収容袋Bの上側開口部が大きく上方に開放された状態となっているので、搬送部7の搬送終端部から根菜類が勢い良く放出されても適確に収容袋B内に収容される。更に、搬送部7の搬送終端部から根菜類が勢い良く放出されて収容袋Bから飛び出てしまわないように、搬送部7の搬送終端部の左右方向外側方に、薄いゴムシートや厚手のビニールシートなどの可撓性シート40jを吊り下げて設けて、搬送部7の搬送終端部から放出する根菜類をこの可撓性シート40jで受け止めて収容袋B内に適確に落下させるようにすることができる。可撓性シート40jは、前記収容袋開口部支持手段40にあっては、ハンガー支持フレーム40eに吊り下げ状態で容易に取付けることができ、また、収容袋開口部支持手段40’にあっては、前後の取付アーム40h,40hに吊り下げ状態で取付けることができる。

本例では、搬送部7の搬送終端側を搬送始端側に設けた軸心が前後方向の軸43回りに上下回動可能に設け、搬送終端側を上下駆動する昇降駆動装置(図例では電動シリンダであるが油圧シリンダでも良い)44を設け、該昇降駆動装置44を作業者が任意に作動操作可能に設けている。作動操作具は、搬送部7の後方に位置する作業者が足で操作可能な足操作具45としている。図例では、座席42より前側のステップ41近傍に設けたペダル式操作具としている。搬送部7の後方に位置する作業者は、搬送部7を搬送される根菜類の選別作業を両手で行いながら、収容袋B内への根菜類の収容状況を確認し、根菜類が収容袋Bの上側開口部附近まで収容されたら、ペダル式操作具45を足で操作して、搬送部7の搬送終端側と収容袋Bの上側開口部を適宜上昇操作する。従って、作業者は選別作業の手を休めずに搬送部7の搬送終端側と収容袋Bの上側開口部を足操作にて上昇操作できて、作業能率も良好となる。また、このペダル式操作具45は上昇操作のみを行うので、操作が単純で選別作業中でも容易に且つ迅速に操作でき、操作性、作業性が良好となる。
In this example, an axis driving center provided on the conveyance start end side of the conveyance unit 7 is provided so as to be vertically rotatable around the axis 43 in the front-rear direction, and an elevating drive device that drives the conveyance termination side up and down (in the example shown in FIG. 44, which is a cylinder but may be a hydraulic cylinder), and the elevating drive device 44 is provided so that an operator can arbitrarily operate it. The operation operation tool is a foot operation tool 45 that can be operated with a foot by an operator located behind the transport unit 7. In the illustrated example, the pedal type operation tool is provided near the step 41 in front of the seat 42. An operator located behind the transport unit 7 confirms the storage status of the root vegetables in the storage bag B while performing the sorting operation of the root vegetables transported through the transport unit 7 with both hands, and the root vegetables are stored in the storage bag. When it is accommodated near the upper opening of B, the pedal-type operation tool 45 is operated with a foot, and the conveyance end side of the conveyance unit 7 and the upper opening of the accommodation bag B are appropriately raised. Accordingly, the operator can raise the transport terminal side of the transport unit 7 and the upper opening of the storage bag B by foot operation without resting the sorting work, and the work efficiency is also improved. Moreover, since this pedal type operation tool 45 performs only the raising operation, the operation is simple and can be operated easily and quickly even during the sorting work, and the operability and workability are improved.
また、ペダル式操作具45を、操作具から足を離したときは非操作時の位置に自動復帰する復帰機構を備え、該ペダル式操作具45を一度押し操作すると、搬送部7の搬送終端側が設定高さ上昇して自動的に停止するように設けると、選別作業中における搬送部7の搬送終端側の上昇操作を迅速に且つ容易に行え作業性、操作性が良好なものとなる。ペダル式操作具45を一度押し操作して搬送部7の搬送終端側が上昇し収容袋開口部支持手段40,40’が上昇するが、この上昇量を15〜25cmに設定すると、根菜類が搬送部7の搬送終端部から収容袋B内に落下したときに割れなどの損傷が生じにくい。
The pedal-type operating tool 45 is provided with a return mechanism that automatically returns to a non-operating position when the foot is removed from the operating tool, and once the pedal-type operating tool 45 is pressed, If the side is provided so that the set height rises and automatically stops, the raising operation on the conveyance end side of the conveyance unit 7 during the sorting operation can be performed quickly and easily, and the workability and operability are good. When the pedal-type operation tool 45 is pressed once to raise the conveyance end side of the conveyance unit 7 and the storage bag opening support means 40, 40 'rises, if this rise is set to 15 to 25 cm, the root vegetables are conveyed Damage such as cracking is less likely to occur when falling into the storage bag B from the conveyance end of the portion 7.
また、上記ペダル式操作具45とは別に搬送部7の搬送終端側を任意の高さに手動で上下操作する手動操作具45aを設けている。これにより、上記ペダル式操作具45によって設定高さ上昇させた後で、収容袋Bの上側開口部の位置をより適正な位置に上下調節することができて、一層、作業性、操作性が良好になる。また、上記ペダル式操作具45による上昇操作は作業中に上昇できる作業上昇上限位置までとし、回収部6で根菜類で満杯になった収容袋Bを機外に排出するときに作業上昇上限位置より更に上方に上昇させて退避させるときや収納上昇位置まで上昇させるときは、手動操作具45aにて行うように構成することで、選別作業中のペダル操作具45の操作によって搬送部7の搬送終端側を作業上昇上限位置より上方に操作してしまって、満杯になった大重量の収容袋を浮上させて大きな負荷がかかり破損するような状況を回避できる。なお、手動操作具45aにて作業上昇上限位置より上方に操作えきるが、選別作業時以外で操作するので、注意が行き届き前記のような状況は容易に気づいて回避できる。また、ペダル式操作具45と手動操作具45aを同時に操作したときには、手動操作具の方が優先して動作する構成としている。足の動作より手の動作に意識が集中するので、安全且つ適確な操作が行える。手動操作具45aは搬送部7の搬送終端側の後側部に取付けていて、搬送部7の後側に位置する作業者のみならず、収容袋Bのセットするために或は満杯の収容袋Bを機外に排出するために機外の回収部近傍に位置する作業者からも容易に操作できて、操作性が良好となる。また、操縦部3に位置する操縦者からも手が届く位置にあれば更に操作性が良好となる。なお、上記構成を示す制御ブロック図を図12に示しており、その図において、制御装置Cと、ペダル式操作具45によって切り替わるスイッチSW1と、手動操作具45aによって切り替わるスイッチSW2と、それらのスイッチSW1,SW2の切り替え信号が入力されて制御装置Cが昇降駆動装置44に制御出力する構成を示している。
In addition to the pedal-type operation tool 45, a manual operation tool 45a for manually moving the conveyance end side of the conveyance unit 7 up and down to an arbitrary height is provided. Thereby, after raising the set height by the pedal-type operating tool 45, the position of the upper opening of the storage bag B can be adjusted up and down to a more appropriate position, further improving workability and operability. Become good. Further, the raising operation by the pedal type operating tool 45 is performed up to a work raising upper limit position that can be raised during the work, and when the collecting bag 6 filled with root vegetables is discharged out of the apparatus, the work raising upper limit position. When it is further lifted upward and retracted or raised to the storage raised position, it is configured to be performed by the manual operating tool 45a, so that the transport of the transport unit 7 can be performed by operating the pedal operating tool 45 during the sorting operation. It is possible to avoid a situation in which the end side is operated above the upper limit position for raising the work, and a large-sized container bag that is full is lifted and is damaged due to a large load. It should be noted that although the manual operation tool 45a can be operated above the work ascending upper limit position, since the operation is performed at other times than the sorting work, the above-mentioned situation can be easily noticed and avoided. In addition, when the pedal-type operation tool 45 and the manual operation tool 45a are operated simultaneously, the manual operation tool operates with priority. Consciousness concentrates on the movement of the hand rather than the movement of the foot, so safe and accurate operation can be performed. The manual operation tool 45a is attached to the rear side portion of the transport portion 7 on the transport end side, and is used not only for the operator positioned on the rear side of the transport portion 7 but also for setting the storage bag B or a full storage bag. Since B is discharged out of the machine, it can be easily operated by an operator located in the vicinity of the collection unit outside the machine, and the operability is improved. Further, the operability is further improved if it is within the reach of the operator located in the control unit 3. A control block diagram showing the above configuration is shown in FIG. 12, in which the control device C, the switch SW1 that is switched by the pedal-type operating tool 45, the switch SW2 that is switched by the manual operating tool 45a, and those switches. A configuration is shown in which a switching signal of SW1 and SW2 is input and the control device C performs control output to the lift drive device 44.
なお、上記のペダル式操作具45をペダルの前後中間部を左右方向の軸回りに回動可能に支持して、ペダル前部を下方回動可能に且つペダル後部を下方回動可能に構成し、更に、前後回動中立位置に自動復帰する復帰機構を設けて、ペダル前部を下方回動操作したときは搬送部7の搬送終端側を上昇動作するように設け、ペダル後部を下方回動操作したときは搬送部7の搬送終端側を下降動作するように設けると、搬送部7の搬送終端側の上下両方向の操作を足操作のみで行え、収容袋Bの上側開口部の位置を上昇させ過ぎたとき下降操作して適正な位置に上下調節することが選別作業中に足操作で行え、一層、作業性、操作性が良好になる。なお、搬送部7の搬送終端側を上昇させる上昇操作ペダルと下降させる下降操作ペダルを別々に設けることもできる。
The pedal-type operation tool 45 is configured such that the middle part of the front and rear of the pedal is supported so as to be pivotable about a left-right axis, the front part of the pedal is pivotable downward, and the rear part of the pedal is pivotable downward. In addition, a return mechanism that automatically returns to the forward / backward rotation neutral position is provided so that when the front part of the pedal is rotated downward, the transport end side of the transport part 7 is moved upward, and the rear part of the pedal is rotated downward. When operated, if the transport end side of the transport unit 7 is provided so as to move downward, the upper and lower directions on the transport end side of the transport unit 7 can be operated only by foot operation, and the position of the upper opening of the storage bag B is raised. When it is too much, it can be lowered and adjusted up and down to an appropriate position by foot operation during the sorting operation, further improving the workability and operability. In addition, the raising operation pedal which raises the conveyance termination side of the conveyance part 7 and the lowering operation pedal which descends can also be provided separately.
作業中に行う搬送部7の搬送終端側の上昇操作は、上記においては、作業者が任意に足或は手で操作して行う構成としているが、搬送部7の搬送終端側の自動上昇させる構成として選別作業中の搬送部7の搬送終端側の上昇操作を不要にし、作業性、操作性を更に向上させることもできる。具体的には、例えば、図13の制御ブロック図に示すように、収容袋Bの底部を受けて支持する支持台39の下側にその支持台39の底面に接して根菜類を収容した収容袋Bの重量を検出するセンサWSを設け、このセンサWSの検出結果に基づいて昇降駆動装置44を駆動制御する構成として、収容袋B内の根菜類の増加に伴う搬送部7の搬送終端側の上昇を自動的に動作させる構成とする。
In the above description, the raising operation on the conveyance end side of the conveyance unit 7 performed during work is configured to be performed manually by an operator by foot or hand. As a configuration, it is not necessary to perform an ascending operation on the conveyance end side of the conveyance unit 7 during the sorting operation, and workability and operability can be further improved. Specifically, for example, as shown in the control block diagram of FIG. 13, the storage containing root vegetables in contact with the bottom surface of the support base 39 on the lower side of the support base 39 that receives and supports the bottom of the storage bag B A sensor WS that detects the weight of the bag B is provided, and the lifting drive unit 44 is driven and controlled based on the detection result of the sensor WS.

本例の根菜類収穫機1は、機体を前後進可能に自走させる走行装置2と、搭乗した操縦者が機体の操縦を行なう操縦部3と、根菜類を圃場から引抜き搬送し茎葉部を切断して根菜類の根部側を収穫する収穫部4と、収穫した根菜類を収容する収容袋Bを設置する回収部6と、前記収穫部4から根菜類を受け取って前記回収部6に搬送する搬送手段5,7を設けた構成とし、更に、前記回収部6に搬送部7によって搬送されてきた根菜類を内側に収容した収容袋Bの底部を支持する支持台39を設け、該支持台39を前下り姿勢或は後下り姿勢に姿勢変更可能に設けている。
The root vegetable harvesting machine 1 of this example includes a traveling device 2 that allows the aircraft to run forward and backward, a maneuvering unit 3 that a piloted operator steers the aircraft, and pulls and conveys root vegetables from the field to remove the foliage portion. The harvesting unit 4 for cutting and harvesting the root side of the root vegetables, the recovery unit 6 for installing the containing bag B for storing the harvested root vegetables, and receiving the root vegetables from the harvesting unit 4 and transporting them to the recovery unit 6 And a support base 39 that supports the bottom of the storage bag B that stores the root vegetables transported by the transport unit 7 in the collection unit 6. The table 39 is provided so that the posture can be changed to the forward descending posture or the backward descending posture.
したがって、回収部6の収容袋Bが根菜類で満杯になってその満杯になった収容袋Bを機外に排出する際に、支持台39を前下り姿勢或は後下り姿勢に姿勢変更するだけで、その傾斜姿勢になった支持台39上を収容袋Bが地面GLまで滑って移動するので、満杯の収容袋Bを地面に降ろす作業が容易に行なえる。また、支持台39の前側或は後側の地面にGLに収容袋Bを降ろす構成なので、地面GLまで収容袋Bを移動させた後は、支持台39を前下り姿勢にして支持台39の前側の地面に収容袋Bを降ろした場合には、機体を後進させるだけで、収容袋Bを支持台39から完全に離して地面に起立状態にさせることができる。支持台39を後下り姿勢にして支持台39の後側の地面に収容袋Bを降ろした場合には、機体を前進させるだけで、収容袋Bを支持台39から完全に離して地面に起立状態にさせることができる。よって、簡単な構成で、且つ、収容袋Bの地面への移動も迅速且つ容易に行なえて作業能率が向上する。
Therefore, when the storage bag B of the collection unit 6 is full of root vegetables and the full storage bag B is discharged out of the apparatus, the posture of the support base 39 is changed to the front descending posture or the rear descending posture. As a result, the storage bag B slides and moves to the ground GL on the support base 39 in the inclined posture, so that the operation of lowering the full storage bag B to the ground can be easily performed. In addition, since the storage bag B is lowered to the GL on the ground on the front side or the rear side of the support base 39, after the storage bag B is moved to the ground GL, the support base 39 is set in a forward downward posture. When the storage bag B is lowered onto the ground on the front side, the storage bag B can be completely separated from the support base 39 and can be made to stand on the ground simply by moving the aircraft backward. When the storage bag B is lowered to the ground on the rear side of the support base 39 with the support base 39 in the rearward down posture, the storage bag B is completely separated from the support base 39 and is stood on the ground simply by moving the aircraft forward. Can be put into a state. Therefore, the operation efficiency is improved by a simple configuration and the storage bag B can be quickly and easily moved to the ground.
本例では、支持台39は、収容袋Bの底面を支持する平坦な上面を有する台部39aと、その台部39aの左右両側に立ち上がる側壁部39b,39bと、台部39aの後側に立ち上がる後壁部39cとを設け、台部39aの前側には立ち上がる壁部を設けず前方に開放状態としたバケット形状としたもので、収容袋Bの底部が支持台39からずれにくく、収容袋Bを確実に支持できるものとなっている。また、台部39aの前側部分は、前上り状態の斜面部39dを形成していて、支持台39を略水平姿勢にして収容袋Bを支持しているときの収容袋Bの前方へのズレを抑制でき、更に、支持台39の前部を前向きに装着した状態で前下り状態に姿勢変更して、或は、支持台39の前部を後向きに装着した状態で後下り状態に姿勢変更して、支持台上の収容袋Bを地面GLに滑らせて移動させるとき、支持台39を水平姿勢から前下り姿勢へ姿勢変更する途中で収容袋Bが滑り落ちようとするが、支持台39の前端部に形成した斜面部39dで収容袋Bを受け止めて、姿勢変更途中での収容袋Bの支持台39上から落下を防止できる。なお、支持台39の前端部を地面GLに接触するまで或は地面GLの上方近傍個所まで下降させたときは、斜面部39dは地面GLに対しては前下り傾斜状態となり、収容袋Bの地面GLへの滑り移動を許容するようになっている。また、支持台39は着脱自在な構成としている。支持台39は、支持台39の後部に設けた係合部39jが回動軸46に固着した係合部材46a,46aに係合した状態で装着され、この係合により、支持台39を傾斜姿勢にしても、支持台39が収納袋Bとともにズレ落ちないようになっている。
In this example, the support base 39 includes a base portion 39a having a flat upper surface that supports the bottom surface of the storage bag B, side wall portions 39b and 39b that rise on both the left and right sides of the base portion 39a, and a rear side of the base portion 39a. A rear wall portion 39c that rises, and is formed in a bucket shape that is not provided with a rising wall portion on the front side of the base portion 39a and is open to the front. The bottom portion of the storage bag B is not easily displaced from the support base 39, and the storage bag B can be reliably supported. In addition, the front portion of the base portion 39a forms a slope portion 39d that is in a front-up state, and the forward shift of the storage bag B when the support bag 39 is supported in a substantially horizontal posture. In addition, the posture is changed to the forward and downward state with the front portion of the support base 39 mounted forward, or the posture is changed to the rear downward state with the front portion of the support base 39 mounted rearward. When the storage bag B on the support base is slid and moved on the ground GL, the storage bag B tends to slide down while the support base 39 is changed from the horizontal posture to the forward and downward posture. The storage bag B can be received by the inclined surface portion 39d formed at the front end portion of the 39, so that the storage bag B can be prevented from dropping from the support 39 during the posture change. When the front end of the support base 39 is brought into contact with the ground GL or lowered to a position near the upper side of the ground GL, the slope 39d is inclined forward and downward with respect to the ground GL. The sliding movement to the ground GL is allowed. The support base 39 is detachable. The support base 39 is mounted in a state where an engaging portion 39j provided at the rear part of the support base 39 is engaged with engagement members 46a and 46a fixed to the rotating shaft 46, and the support base 39 is inclined by this engagement. Even in the posture, the support base 39 is prevented from slipping off together with the storage bag B.
支持台39の姿勢変更機構は、図例では、着脱自在の支持台39を下側から支持する支持部材39eの後端部に軸心横方向の回動軸46を一体的に取付け、該回動軸46を機体側に回動可能に取付け、更に、該回動軸46を回動操作して支持台39を略水平姿勢から前下り姿勢に変更可能にする姿勢変更操作機構を連結している。回動軸46の機体側への取付け構成は、機体フレーム17に取付けブラケット17a,17a;17a,17aを固着し、一方、機体フレーム17の右側部の前後に伸びるフレーム部に沿って前後にのびる縦フレーム39fを設け、該縦フレーム39fに固着の取付けブラケット39g,39g,39g,39gとを前後方向の取付け軸6a,6aを介して連結している。また、縦フレーム39fの後端部には左右方向外方側にのびる横フレーム39hを固着し、更に、その横フレーム39hの外端部に支持プレート39iを取付け、この支持プレート39iと縦フレーム39fとに回動軸46の左右両端部を回動自在に取付けている。そして、姿勢変更操作機構として、回動軸46の外端部近傍に一体にアーム47を取付け、該アーム47にネジ部の回動によって伸縮可能な伸縮ロッド48を連結し、また、該伸縮ロッド48の後端側を支持する支持部49を設け、伸縮ロッド48のネジ部を回動して伸縮操作する操作ハンドル50を設け、その操作ハンドル50の回動操作により伸縮ロッド48が伸縮動作し、これによりアーム47とともに回動軸46と支持部材39eが回動して支持台39が回動軸46回りに回動するように構成している。これらの支持台構成部材は、姿勢変更操作機構も含めて、取付軸6a,6a回りに上方回動させて機体側に適宜設けた支持具で支持し、収納状態にすることができるようになっている。また、姿勢変更操作機構は機体後部側に配置しているので、選別作業者用搭乗部41,42に搭乗する作業者が容易に操作でき、操作性が良い。なお、別の図例に示すように、支持台39の回動軸心となる回動軸46を支持台39に対して前側に配置して、支持台39を略水平姿勢から後下り姿勢に変更可能とする構成とすることもできる。
In the illustrated example, the posture changing mechanism of the support base 39 is integrally attached to a rear end portion of a support member 39e that supports the detachable support base 39 from the lower side. A moving shaft 46 is pivotally attached to the machine body, and a posture changing operation mechanism that allows the support base 39 to be changed from a substantially horizontal posture to a forward and downward posture by rotating the rotating shaft 46 is connected. Yes. The mounting structure of the rotating shaft 46 on the machine body side is such that the mounting brackets 17a, 17a; 17a, 17a are fixed to the machine body frame 17 and extend back and forth along a frame portion extending forward and backward on the right side portion of the machine body frame 17. A vertical frame 39f is provided, and fixed mounting brackets 39g, 39g, 39g, 39g are connected to the vertical frame 39f via mounting shafts 6a, 6a in the front-rear direction. Further, a horizontal frame 39h extending outward in the left-right direction is fixed to the rear end portion of the vertical frame 39f, and a support plate 39i is attached to the outer end portion of the horizontal frame 39h, and the support plate 39i and the vertical frame 39f are attached. And both left and right end portions of the rotation shaft 46 are rotatably attached. Then, as an attitude change operation mechanism, an arm 47 is integrally attached in the vicinity of the outer end portion of the rotation shaft 46, and an expansion / contraction rod 48 that can be expanded and contracted by rotation of a screw portion is connected to the arm 47. A support portion 49 that supports the rear end side of the 48 is provided, and an operation handle 50 that rotates and extends the screw portion of the expansion rod 48 is provided. The rotation of the operation handle 50 causes the expansion and contraction rod 48 to expand and contract. Thus, the rotation shaft 46 and the support member 39e are rotated together with the arm 47 so that the support base 39 is rotated around the rotation shaft 46. These support base components, including the posture changing operation mechanism, can be turned up around the mounting shafts 6a and 6a and supported by a support provided appropriately on the machine body side to be in a stored state. ing. In addition, since the posture changing operation mechanism is arranged on the rear side of the machine body, the operator boarding the sorting worker boarding portions 41 and 42 can easily operate and the operability is good. In addition, as shown in another example of the figure, a pivot shaft 46 that serves as a pivot axis of the support base 39 is disposed on the front side with respect to the support base 39, so that the support base 39 is changed from a substantially horizontal posture to a rear descending posture. It can also be set as the structure which can be changed.
姿勢変更操作機構は、上記のように手動操作可能な構成にすれば、低コストで簡易な構成となる。また、上記姿勢変更操作機構の伸縮ロッドに変えて電動シリンダや油圧シリンダなどの伸縮駆動体48aとし、操作ハンドル50に変えて、伸縮駆動体48aを伸縮駆動操作するスイッチ等の操作具を操縦部3に設けた構成とすると、支持台39の姿勢変更操作を迅速且つ容易に行え、また、操縦部3に搭乗した操縦者が支持台39の姿勢変更操作を行なって収容袋Bを地面に移動させることができ、そして、その操作に続いて機体を前進或は後進操作できるので、収容袋Bを地面に降ろす作業を一層迅速に行なえ、作業性が一層向上する。
If the posture changing operation mechanism is configured to be manually operable as described above, the configuration is low and simple. Further, the telescopic drive body 48a such as an electric cylinder or a hydraulic cylinder is used instead of the telescopic rod of the posture changing operation mechanism, and an operation tool such as a switch for operating the telescopic drive body 48a to extend and retract is replaced with the operation handle 50. 3 allows the posture changing operation of the support base 39 to be performed quickly and easily, and the operator who has boarded the control section 3 performs the posture changing operation of the support base 39 to move the containing bag B to the ground. Since the machine body can be moved forward or backward following the operation, the work of lowering the containing bag B to the ground can be performed more quickly, and the workability is further improved.
なお、支持台39を後下り姿勢にして支持台39の後側の地面に収容袋Bを降ろす構成とした場合には、収容袋Bが支持台39上を滑り落ち難いときに機体後部に搭乗するようにした作業者が機体後方に収容袋Bを引っ張ることが迅速に行なえる。
In the case where the support bag 39 is placed in a rear-down position and the storage bag B is lowered onto the ground on the rear side of the support table 39, when the storage bag B is difficult to slide down on the support table 39, boarding the rear part of the aircraft Thus, the operator can quickly pull the storage bag B behind the machine body.
図20〜24には、回収部6’で回収された根菜類が満杯になった収容袋Bを機体上に積載しておく積載部51を回収部6’の機体前側に設け、回収部6’上の収容袋Bを前方に移動させて積載部51上に移動可能に設けた構成のものを示している。このように構成すると、満杯になった収容袋Bを機体上に積載して収穫作業を継続できて、収穫作業の能率向上が図れ、また、収穫作業を圃場端まで継続してから満杯になった収容袋Bを地面に降ろすこともできて、満杯になった収容袋Bの回収作業も迅速に行なえて、収穫した根菜類の運搬作業の能率向上も図れる。
20 to 24, a loading unit 51 is provided on the front side of the body of the collection unit 6 ′ in which the storage bag B filled with the root vegetables collected by the collection unit 6 ′ is loaded on the body. The upper storage bag B is moved forward and is configured to be movable on the stacking unit 51. If comprised in this way, the container B which became full can be loaded on a body, and a harvesting operation can be continued, the efficiency of a harvesting operation can be improved, and it will become full after continuing a harvesting operation to the field end. The storage bag B can be lowered to the ground, and the full storage bag B can be collected quickly, thereby improving the efficiency of carrying the harvested root vegetables.
また、収容袋Bを支持する支持台39を回収部6’から積載部51にわたって複数着脱自在に設置可能とし、支持台39を回収部6’から前方に移動させて積載部51上に移動可能に設けた構成としたので、収容袋Bを支持台39上に載置した状態のままで回収部6’から積載部51に迅速に移動でき、且つ、積載部51において安定した状態で満杯の収容袋Bを積載しておくことができる。
In addition, a plurality of support bases 39 that support the storage bag B can be detachably installed from the collection unit 6 ′ to the stacking unit 51, and the support bases 39 can be moved forward from the recovery unit 6 ′ onto the stacking unit 51. The storage bag B can be quickly moved from the collection unit 6 ′ to the stacking unit 51 while being placed on the support base 39, and the stacking unit 51 is filled in a stable state. The storage bag B can be loaded.
回収部6’から積載部51にわたって横軸回りに回動自在のローラ52…を複数設けて、該ローラ52…上に支持台39を設置して移動させる構成としたので、回収部6’から積載部51への収納袋Bの移動を、比較的軽い力で移動させることができ、移動機構を簡略化が図れる。
A plurality of rollers 52... That can rotate around the horizontal axis from the collection unit 6 ′ to the stacking unit 51 are provided, and the support base 39 is installed on the rollers 52. The storage bag B can be moved to the loading unit 51 with a relatively light force, and the moving mechanism can be simplified.
また、積載部51で支持台39を支持する支持部材39e’を略水平姿勢から前下がり姿勢に姿勢変更可能に設けたので、積載部51に積載した根菜類を収容した収容袋Bを地面に容易に且つ迅速に降ろすことができて、作業能率が良好なものとなる。
Further, since the support member 39e ′ for supporting the support base 39 by the stacking portion 51 is provided so that the posture can be changed from a substantially horizontal posture to a forward-downward posture, the storage bag B storing the root vegetables loaded on the stacking portion 51 is placed on the ground. It can be lowered easily and quickly, and the working efficiency is good.
更に、回収部6’から積載部51まで支持台39を移動させると、支持台39の一部(本例では係合部39j)と支持台39を支持する側に設けた係合部材46a’とが係合して支持台39の前方への移動を規制する構成としたので、積載部51で支持台39を略水平姿勢から前下がり姿勢に姿勢変更したとき、収容袋Bとともに支持台39がズレ落ちないようになり、よって、支持台39を下に敷いた状態で収容袋Bが地面に降ろされてしまうことがなく、作業能率が良好なものとなる。
Further, when the support base 39 is moved from the collection unit 6 ′ to the stacking unit 51, a part of the support base 39 (engagement portion 39 j in this example) and an engagement member 46 a ′ provided on the side that supports the support base 39. Is engaged to restrict the forward movement of the support base 39. Therefore, when the support base 39 is changed from a substantially horizontal position to a front-down position by the loading portion 51, the support base 39 together with the containing bag B is supported. Therefore, the storage bag B will not be lowered to the ground with the support base 39 laid down, and the work efficiency will be good.
なお、前記の構成と比べると、回収部6’には姿勢変更機構は設けていない構成であり、積載部51に、収容袋Bを支持する支持台39を略水平姿勢から前下り傾斜姿勢に姿勢変更する姿勢変更機構を設けた構成となっている。また、支持台39の姿勢変更機構の具体的構成は、前記の回収部6の支持台39の姿勢変更機構と同様な機構を採用している。図例では、同じ機能を有する部分については同じ符号を付している。
Compared to the above configuration, the collection unit 6 ′ is not provided with a posture changing mechanism, and the support base 39 that supports the containing bag B is placed on the stacking unit 51 from a substantially horizontal posture to a forward and downward inclined posture. The posture changing mechanism for changing the posture is provided. The specific structure of the posture changing mechanism of the support base 39 employs the same mechanism as the posture changing mechanism of the support base 39 of the collection unit 6 described above. In the figure, the same reference numerals are given to parts having the same function.
上記構成とした根菜類収穫機において、回収部6’に設置した収容袋Bが回収された根菜類で満杯になったときは、回収部6’から積載部51にその収容袋Bを移動させる。このとき、支持台39は、横軸回りに回転自在のローラ52…を回収部6’から積載部51にわたって複数設けた支持部53上に支持させた構成としているので、積載部51上にある何も積載していない支持台39を取り外し、その後、作業者が根菜類で満杯になった収容袋Bを前方に押すことで、収容袋Bを上に載せた支持台39を、支持部53のローラ52…を回転させながら支持部53上を前方に容易に移動させることができる。積載部51には、支持台39を下側から支持する横軸回りに回転自在のローラ52…を複数設けた支持部材39e’を設けていて、その後端部を前記と同様な軸心横方向の回動軸46に一体的に取付け、この回動軸46を、前記と同様な、アーム47、伸縮ロッド48、支持部49、操作ハンドル50によって構成した姿勢変更操作機構によって、回動軸46を回動操作して支持部材39e’とともに支持台39を回動軸46回りに回動させて略水平姿勢から前下り傾斜姿勢に姿勢変更できるように構成している。なお、これら手動操作機構に代えて駆動機構を用いて姿勢変更する構成とすることもできる。回収部6’から満杯の収容袋Bを積載部51上に移動させたら、先に取り外しておいた収容台39を、回収部6’上に設置する。そして、収穫作業を継続する。その後、再び、回収部6’に設置した収容袋Bが満杯になったら、まず、積載部51上の収容袋Bをその支持台39を前下り状態に姿勢変更し、前記と同様に地面に降ろす。そして、積載部51の支持台39を元の略水平姿勢に姿勢を戻して、再び、回収部6’から満杯の収容袋Bを積載部51上に移動させる。そしてまた、その積載部51上に移動させた収容袋Bをその支持台39を前下り状態に姿勢変更し、前記と同様に地面に降ろす。このように作業を進めると、収穫作業の能率向上が図れる。また、積載部51に満杯の収容袋Bを移動した後で回収部6’に再び設置した収容袋Bが満杯になる前に、機体が圃場端に至ったときに、収容袋Bを積載部51から地面に降ろすこともできる。このようにすれば、根菜類を収容した収容袋Bの回収作業を迅速に行なえて、収穫した根菜類の運搬作業の能率向上も図れる。
In the root vegetable harvesting machine configured as described above, when the storage bag B installed in the recovery unit 6 ′ is filled with the recovered root vegetables, the storage bag B is moved from the recovery unit 6 ′ to the loading unit 51. . At this time, the support base 39 has a structure in which a plurality of rollers 52... Rotatable around the horizontal axis are supported on a plurality of support parts 53 provided from the collection part 6 ′ to the stacking part 51. The support base 39 on which nothing is loaded is removed, and then the operator pushes the storage bag B filled with root vegetables forward so that the support base 39 with the storage bag B placed thereon is supported by the support portion 53. These rollers 52 can be easily moved forward on the support portion 53 while rotating the rollers 52. The stacking portion 51 is provided with a support member 39e 'provided with a plurality of rollers 52 that are rotatable around a horizontal axis for supporting the support base 39 from the lower side, and the rear end portion thereof is in the same axial direction as that described above. The rotation shaft 46 is integrally attached to the rotation shaft 46, and the rotation shaft 46 is attached to the rotation shaft 46 by an attitude change operation mechanism constituted by the arm 47, the telescopic rod 48, the support portion 49, and the operation handle 50, as described above. And the support base 39 together with the support member 39e 'is rotated about the rotation shaft 46 so that the posture can be changed from a substantially horizontal posture to a forward and downward tilt posture. In addition, it can also be set as the structure which replaces with these manual operation mechanisms and changes an attitude | position using a drive mechanism. When the full storage bag B is moved from the collection unit 6 ′ onto the stacking unit 51, the storage table 39 previously removed is placed on the collection unit 6 ′. Then, the harvesting operation is continued. After that, when the storage bag B installed in the collection unit 6 ′ is full again, first, the storage bag B on the stacking unit 51 is changed in posture to the support base 39 in the front-down state, and is placed on the ground in the same manner as described above. take down. Then, the support base 39 of the stacking unit 51 is returned to the original substantially horizontal posture, and the full storage bag B is moved again from the collection unit 6 ′ onto the stacking unit 51. Further, the posture of the storage bag B moved onto the stacking portion 51 is changed to the front descending state and lowered onto the ground in the same manner as described above. If the work is advanced in this way, the efficiency of the harvesting work can be improved. In addition, after the full storage bag B is moved to the stacking unit 51 and before the storage bag B installed in the collecting unit 6 ′ is full, the storage bag B is loaded into the stacking unit when the machine body reaches the end of the field. 51 can be lowered to the ground. In this way, the collection work of the storage bag B containing the root vegetables can be quickly performed, and the efficiency of the transporting work of the harvested root vegetables can be improved.
回収部6’に設置した支持台39は、その後側に設けたストッパ54と積載部51に設置した支持台39に挟まれて前後に大きくずれることがないように設けている。積載部51に設置した支持台39は、前下りに姿勢変更したときに支持台39がズレ落ちないように、支持台39の一部(本例では係合部39j)と支持台39を支持する側に設けた係合部材46a’とが係合して支持台39の前方への移動が規制されているので、回収部6’に設置した支持台39が前側にずれて積載部51に設置した支持台39に当っても、それ以上前側にずれることがなく、積載部51の支持台39のズレ止め機構が、回収部6’に設置した支持台39の前側へのズレ止めも兼ねて、構成の簡略化が図られている。また、回収部6’に設置した支持台39の左右方向へのズレ止めは支持部53に設けた左右ガイド55,55によって行われ、積載部51に設置した支持台39の左右方向へのズレ止めは支持部材39e’に設けた左右ガイド56,56によって行われる。
The support base 39 installed in the collection unit 6 ′ is provided so as not to be greatly displaced back and forth between the stopper 54 provided on the rear side and the support base 39 installed in the stacking unit 51. The support base 39 installed on the stacking unit 51 supports a part of the support base 39 (in this example, the engaging portion 39j) and the support base 39 so that the support base 39 does not fall off when the posture is changed to forward and downward. Since the forward movement of the support base 39 is restricted by the engagement with the engaging member 46a ′ provided on the side to be supported, the support base 39 installed in the recovery section 6 ′ is shifted to the front side to the stacking section 51. Even if it hits the installed support base 39, it does not shift further forward, and the mechanism for preventing the shift of the support base 39 of the stacking unit 51 also serves to stop the front of the support base 39 installed in the collection unit 6 '. Thus, the configuration is simplified. Further, the right and left guides 55 and 55 provided in the support part 53 are used to stop the support base 39 installed in the collection unit 6 ′ in the left and right direction. Stopping is performed by left and right guides 56, 56 provided on the support member 39e '.
図8に示すように、選別作業者用搭乗部41,42の座席42の前側で搬送部7の後側には、搬送部7で搬送される根菜類から選別し取出した不良な根菜類を圃場に落下案内する落下通路57の投入部を配置している。選別作業者用搭乗部41,42の前側には搬送部7と操縦部3があり、左側には収穫部4の後部と残葉処理部5があり、右側には回収部6があるため、取出した不良な根菜類は、機体の前側及び左右側方には投げ捨てられない。前向きで後方に投げ捨てると、投げた不良な根菜類が過って未収穫の圃場側に飛んでいってしまうことがあり、収穫の障害となる恐れがある。そこで、本例では、作業者は前向きに座って搬送部7で搬送される根菜類の選別作業を行いながら、作業者の前側にある落下通路57内に投入して不良な根菜類を圃場の適確な個所に落して行くことができる。落下通路57は、ステップ41を貫通して機体下方の圃場に達するように形成した筒状の案内通路によって構成し、或は、座席42の前側下方個所から座席42の下方を通って機体後方に延びるスロープ状のシュータで構成することもできる。収穫部4の切断装置31により切断されて根菜類の根部から切り離された茎葉部は、収穫部4の茎葉搬送ベルト32,32で機体後方に搬送されて、その搬送ベルトの後端部から後方に放出される。放出された茎葉部は、隣接する未収穫側圃場に落下しないように排葉シューター58によって機体の左右方向内側に寄せながら落下させるように設けている。また、茎葉部が落下排出される排葉シューター58の下側排出部58aは、選別作業者用搭乗部41,42の座席42より後側になるように設けているので、座席42に座る作業者に落下排出される茎葉部がかからず、快適に作業が行える。なお、茎葉部が落下排出される排葉シューター58の下側排出部58aが、選別作業者用搭乗部41,42の座席42の下方に位置するように排葉シューター58の下部を延設すれば、座席42に座る作業者に落下排出される茎葉部がかからないようにしつつ、排葉シューター58を機体後方にあまり突出させないで設けられ、機体のコンパクト化が図れる。また、選別作業者用搭乗部41,42の座席42の左側方には、残葉処理部5を配置していて、残葉処理ローラ38から機体右側個所の第一コンベア36は、残葉処理ローラ38によって取り除かれた茎葉部が搬送され、その茎葉部が搬送終端部から落下する。第一コンベア36の搬送終端部の下方は開口されていて、第一コンベア36の搬送終端部から落下した茎葉部はその開口部を通過して圃場に落下する。なお、残葉処理部5の上側を安全のためにカバー5aで覆うように設けても良い。この場合、そのカバー5aを第一コンベア36の搬送終端部の右側方及びその下方まで延長して覆って、その延長したカバー部が第一コンベア36の搬送終端部から落下した茎葉部を圃場に落下させるために下方に形成した前記開口部に案内するガイドを兼ねるようにする。そして、残葉処理ローラ38から機体右側の第一コンベア36の搬送終端側上方のカバー5aには開口部5bを設けていて、この開口部5bに、搬送部7で搬送される根菜類から選別されて取出した不良な根菜類を投入することもできる。開口部5bに投入された不良な根菜類は、残葉処理ローラ38によって取り除かれた茎葉部とともに、第一コンベア36の搬送終端部から落下し、その下方に形成した前記開口部を通って圃場に落下する。(図8参照)
なお、従来の根菜類収穫機は、特開平2004−89063号公報に記載されているように、機体を自走させる走行装置と、搭乗した操縦者が機体の操縦を行なう操縦部と、根菜類を圃場から引抜き搬送し茎葉部を切断して根菜類の根部側を収穫する収穫部と、収穫した根菜類を収容する収容袋を設置する回収部と、前記収穫部から収穫物を受け取って前記収容部に搬送する搬送部を設け、機体の左側部に前側から後側にわたって前記収穫部を配置し、機体の右側前部に前記操縦部を配置するとともに、該操縦部の後方近傍に前記回収部を配置し、前記搬送部に、前記収穫部側から前記収容部の後方個所に向けて横方向に搬送する横搬送部と、該横搬送部から根菜類を引継いで機体後側から前側上方に持上げ搬送して前記回収部に設置した収容袋の上側開口部内に根菜類を放出する縦搬送部を設けた構成とした根菜類収穫機がある。そして、この根菜類収穫機は、横搬送部で搬送される根菜類を、該横搬送部の前側或は後側に位置する作業者が選別作業する構成とし、また、回収部には、回収部で根菜類が大きく落下して損傷するようなことがないように、収容袋の底部を昇降可能に支持する昇降台を設け、回収初期に昇降台を上昇させて収容袋内に入り込んでくる根菜類の落下距離を小さくし、根菜類の回収量の増大に伴い昇降台を下降させていく構成としている。更に、回収部に設置した収容袋が根菜類で満杯になってその収容袋を機外に取出すときは、昇降台を機体側方に引き出して下降回動させて取出す構成としている。
As shown in FIG. 8, defective root vegetables selected and extracted from the root vegetables transported by the transport unit 7 are disposed on the front side of the seat 42 of the boarding units 41 and 42 for the sorting workers and on the rear side of the transport unit 7.

You can drop it to the right place. The fall passage 57 is configured by a cylindrical guide passage formed so as to pass through the step 41 and reach the farm field below the fuselage, or from the front lower part of the seat 42 to the rear of the fuselage through the lower part of the seat 42. It can also be composed of an elongated slope-like shooter. The foliage cut by the cutting device 31 of the harvesting unit 4 and cut off from the root of the root vegetable are conveyed to the rear of the machine body by the foliage conveying belts 32 and 32 of the harvesting unit 4 and rearward from the rear end of the conveying belt. To be released. The discharged foliage portion is provided so as to be dropped while being moved inward in the left-right direction of the machine body by the leaf shooter 58 so as not to fall into the adjacent unharvested farm field. Further, the lower discharge portion 58a of the leaf shooter 58 from which the foliage is dropped and discharged is provided on the rear side of the seat 42 of the sorting workers' riding portions 41 and 42, so that the operation of sitting on the seat 42 is performed. It does not take the foliage that is dropped and discharged by the person, and the work can be done comfortably. In addition, the lower part 58a of the leaf shooter 58 from which the foliage is dropped and discharged extends the lower part of the leaf shooter 58 so that the lower discharge portion 58a is located below the seat 42 of the boarding portions 41 and 42 for sorting workers. For example, the leaflet shooter 58 is provided so as not to protrude too much to the rear of the machine body, while preventing the fallen and discharged stems and leaves from being placed on the operator sitting on the seat 42, so that the machine body can be made compact. Further, a remaining leaf processing section 5 is arranged on the left side of the seat 42 of the sorting sections 41 and 42 for sorting workers, and the first conveyor 36 located at the right side of the machine body from the remaining leaf processing roller 38 is configured to perform the remaining leaf processing. The foliage removed by the roller 38 is conveyed, and the foliage falls from the conveyance end. The lower part of the conveyance termination part of the 1st conveyor 36 is opened, and the foliage part which fell from the conveyance termination part of the 1st conveyor 36 passes the opening part, and falls to a farm field. In addition, you may provide so that the upper side of the remaining leaf process part 5 may be covered with the cover 5a for safety. In this case, the cover 5a is extended to the right side of the conveyance end portion of the first conveyor 36 and to the lower side thereof, and the foliage portion that has fallen from the conveyance end portion of the first conveyor 36 is applied to the field. In order to make it fall, it serves as a guide guided to the opening formed below. An opening 5b is provided in the cover 5a above the conveyance end side of the first conveyor 36 on the right side of the machine body from the remaining leaf processing roller 38, and the opening 5b is selected from the root vegetables conveyed by the conveyance unit 7. It is also possible to put in bad root vegetables that have been removed. Defective root vegetables thrown into the opening 5b fall from the conveying terminal end of the first conveyor 36 together with the foliage removed by the remaining leaf processing roller 38, and pass through the opening formed below the field. Fall into. (See Figure 8)

If each upper lid d, d, d, d is rolled out outside the bag (outside each side part a, a, b, b), the upper opening g of the storage bag B is opened, If the upper lids d, d, d, d are brought close to the inside of the bag (inside each side part a, a, b, b) and squeezed and tied with the string f passed through the upper lid, they are accommodated in the accommodation bag B. The upper lids c, c, c, c can be closed so that the contents do not easily pop out.
また、収容袋Bは、角筒状に形成した左右の側部a,aの前後幅Lが前後の側部b,bの左右幅Wより大きく、側部a,a,b,bの上下幅Hを左右の側部a,aの前後幅Lより小さく或は同じ幅とし且つ前後の側部b,bの左右幅Wより大きく設定している。このように形成した収容袋Bは、農作物収穫機の左右一側部に左右の側部a,aが機体の左右側方に向いた状態で載置することで、農作物収穫機から機体外側方に収容袋Bが大きくはみ出すことがなく、収容袋装着時の農作物収穫機の機体幅をコンパクトにできる。更に、左右の側部a,aの前後幅Lは前後の側部b,bの左右幅Wより大きく設定し、且つ、側部a,a,b,bの上下幅Hを左右の側部a,aの前後幅Lより大きくならないように設定しているので、収容袋Bの収容量を大きくしつつ、できるだけ高さを低くしたものとなり、よって、収容袋Bの底部側に収容された農作物がその上側に載っている農作物の重量を受けることになるが、収容袋Bの高さを低くしているので、底部側に収容された農作物が傷みにくく、また、農作物を収容した収容袋Bを農作物収穫機から地面に降ろしたときに、大きく傾かないで自立し易いものとなる。更には、農作物を収容した収容袋Bを洗浄機等の上方に移動するときなどに、収容袋Bの高さを低くしていることによって、低い屋内の天井に収容袋Bの上部や収容袋Bを吊上げたフォークリフトのフォークが当ったりすることが生じ難くなる。
Further, the storage bag B has a rectangular tube-shaped left and right side portions a and a whose front and rear width L is larger than the front and rear side portions b and b and the left and right side widths W, and the side portions a, a, b and b are vertically The width H is set to be smaller than or equal to the front-rear width L of the left and right side portions a, a and larger than the left-right width W of the front and rear side portions b, b. The storage bag B formed in this manner is placed on the left and right sides of the crop harvesting machine with the left and right sides a and a facing the left and right sides of the aircraft, so Therefore, the storage bag B does not protrude greatly, and the width of the crop harvesting machine when the storage bag is mounted can be made compact. Furthermore, the front-rear width L of the left and right side parts a, a is set larger than the left-right width W of the front and rear side parts b, b, and the vertical width H of the side parts a, a, b, b is set to the left and right side parts. Since it is set not to be larger than the front-rear width L of a and a, the height of the accommodation bag B is increased while the height is lowered as much as possible, so that it is accommodated on the bottom side of the accommodation bag B. Although the crop receives the weight of the crop on the upper side, the height of the storage bag B is lowered, so that the crop stored on the bottom side is hard to be damaged, and the storage bag that stores the crop When B is lowered from the crop harvesting machine to the ground, it becomes easy to stand on its own without tilting greatly. Further, when the storage bag B storing the crops is moved upward such as a washing machine, the height of the storage bag B is lowered, so that the upper part of the storage bag B or the storage bag is placed on the low indoor ceiling. It is difficult for the fork of the forklift that lifts B to hit.
前後の側部b,bの左右幅Wより前後幅Lを大きく設定した左右の側部a,aに、吊上げ用の吊手h,hを縫い付けている。この吊手にフォークリフトのフォークFを突っ込んで上昇して収容袋Bを吊上げることができる。
Lifting hoists h and h are sewn to the left and right side portions a and a having a front and rear width L set larger than the left and right width W of the front and rear side portions b and b. The forklift fork F can be pushed into the suspension and lifted to lift the storage bag B.
また、収容袋Bの互いに対向する側部、本例では左右の側部a,aの各上端部には、それぞれ左右両端側に、収容袋Bの上側開口部gを支持具(上記根菜類収穫機の収容袋開口支持手段40或は40’のフック状の支持具40b…)を引っかけるための孔j,j,j,jを設けている。この孔に支持具を引っかけることで、収容袋Bの上側開口部gを広げた状態で支持することができる。更に、その左右両側の孔の左右間にも一つ或は複数の孔k,kを設けている。これにより、左右両側の孔j,j,j,jに支持具を引っかけて収容袋Bの上側開口部gを広げた状態で支持し、その上側開口部gの上方に収容袋Bの一側方(前後一側方)から入り込むように搬送部(上記根菜類収穫機にあっては前記搬送部7の搬送終端側)を配置し、その搬送部から排出されるものが適確に収容袋B内に入り込んでいくように、前記左右両側の孔の左右間に設けた孔k,kにも支持具を引っかけて支持することで、前記左右両側の孔の間の上側開口部が弛んで、搬送部から排出されたものが収容袋Bの外にこぼれ落ちてしまうのを確実に防止できる。なお、上側開口部gを広げて支持する支持具は収容袋Bの内側から前記の孔に引っかける。このとき、各上蓋d,d,d,dは袋の外側(各側部a,a,b,bの外側)にまくるようにして出して、上蓋が収容させたものとともに収容袋Bの内側に入り込んでしまって後で上蓋を引き出し難くならないようにする。なお、孔に代えてループを縫い付けて設けても良い(図示省略)。図26は、上記根菜類収穫機の収容袋開口支持手段40或は40’のフック状の支持具40b…で支持した状態を示している。
Moreover, the upper opening g of the storage bag B is provided on the side portions of the storage bag B facing each other, in this example, the upper ends of the left and right side portions a, a on both left and right ends, respectively. Holes j, j, j, j are provided for hooking the storage bag opening support means 40 or 40 'hook-shaped support 40b ...) of the harvesting machine. By hooking the support in this hole, the upper opening g of the storage bag B can be supported in an expanded state. Further, one or a plurality of holes k, k are provided between the left and right holes on the left and right sides. As a result, a support is hooked into the holes j, j, j, j on both the left and right sides and the upper opening g of the storage bag B is expanded and supported, and one side of the storage bag B is located above the upper opening g. The transport section (the transport end side of the transport section 7 in the case of the root vegetable harvesting machine) is disposed so as to enter from the side (one side in the front and rear sides), and what is discharged from the transport section is an appropriate storage bag The upper opening between the left and right holes is loosened by supporting the hooks in the holes k, k provided between the left and right holes so as to enter into B. It is possible to reliably prevent the material discharged from the transport unit from spilling out of the storage bag B. In addition, the support which expands and supports the upper side opening part g is hooked in the said hole from the inner side of the storage bag B. FIG. At this time, each upper lid d, d, d, d is taken out so as to roll outside the bag (outside each side part a, a, b, b) and inside the containing bag B together with what the upper lid contains. Make sure that it does not become difficult to pull out the upper lid later. In place of the hole, a loop may be sewn (not shown). FIG. 26 shows a state in which the root vegetable harvester is supported by the storage bag opening support means 40 or the hook-shaped support 40b of 40 '.
更に、底部cには、その底部の中央側の一部を開口した下側開口部mを形成しており、更に、この開口部mを塞ぐ二重の底蓋n,pを設けている。この底蓋n,pには、上蓋のように紐qを通していて、この紐qを縛って下側開口部mを容易に開放しないよう閉じている。この下側開口部mは、フォークリフトのフォークなどで収容袋Bを吊上げて、収容したものを袋の外に排出するとき、吊上げた収容袋Bの底部cの下側にある紐qをほどくことで開くことができ、内容物の排出を迅速且つ容易に行なえる。
Further, the bottom c is formed with a lower opening m that opens a part on the center side of the bottom, and further, double bottom lids n and p that close the opening m are provided. The bottom lids n and p are passed through a string q like an upper lid, and the string q is tied so that the lower opening m is not easily opened. The lower opening m unwinds the string q below the bottom c of the lifted storage bag B when the storage bag B is lifted with a fork of a forklift and the stored bag is discharged out of the bag. The contents can be quickly and easily discharged.
また、図29のように、互いに対向する側部a,a,b,bを支持し合う紐r、rやバンドを袋の内側に設けると、収容袋が膨らんで地面に自立し難くなるのを防止できる。図27に示すように、互いに対向する側部a,aに二つずつ吊手h’,h’,h’,h’を並べて設けると、横長の収容袋をフォークリフトの二つ並んだフォークF,Fを各吊手h’,h’,h’,h’に突っ込んで傾かないようにして吊上げることができる。
Also, as shown in FIG. 29, if the strings r, r, and bands that support the side portions a, a, b, and b facing each other are provided inside the bag, the containing bag swells and it becomes difficult to stand on the ground. Can be prevented. As shown in FIG. 27, when two hangeres h ′, h ′, h ′, h ′ are arranged side by side on the side portions a, a facing each other, fork F in which a horizontally long storage bag is arranged in two forklifts. , F can be lifted so as not to tilt by thrusting into each of the hangeres h ′, h ′, h ′, h ′.
また、図25、図30に示すように、収容袋Bの周囲に棒STなどを突っ込めるような隙間s’を一部に開けた状態のバンドsを設けると、前記根菜類収穫機の支持台39を傾斜させて収容袋Bを地面に移動させた後、支持台39を収容袋Bから離れるように機体を移動させるとき、収容袋Bが引きずられて移動しないようにバンドsの隙間s’に棒STを突っ込んでその引きずりを食い止めることができる。また、図31に示すように、前記根菜類収穫機の支持台39を傾斜させて収容袋Bを地面に移動させるときに、収容袋Bが傾斜方向に倒れないように吊手h,hを引っかけて機体に支持させるフックhfを機体に設けることができる。
Further, as shown in FIGS. 25 and 30, when a band s with a gap s ′ into which a stick ST or the like is inserted is provided around the storage bag B, a support stand for the root vegetable harvesting machine is provided. After moving the storage bag B to the ground by tilting 39, when the machine body is moved away from the storage bag B, the gap s ′ of the band s is prevented so that the storage bag B is not dragged and moved. You can stop the drag by sticking the stick ST. In addition, as shown in FIG. 31, when the support bag 39 of the root vegetable harvesting machine is tilted and the storage bag B is moved to the ground, the hanger h and h are attached so that the storage bag B does not fall in the tilt direction. A hook hf that is hooked and supported by the airframe can be provided on the airframe.
