Description
本発明は、乗用補助台車に関し、詳しくは、歩行型畝跨ぎ式管理機に装着される乗用補助台車と、該乗用補助台車を装着した歩行型畝跨ぎ式管理機に関するものである。 TECHNICAL FIELD The present invention relates to a riding auxiliary trolley, and more particularly, to a riding auxiliary trolley mounted on a walking type ridge straddling type tending machine, and to a walking type ridge straddling type tending machine equipped with the riding type auxiliary trolley.
従来、畑作管理作業を行う際、管理機により一条毎に畝溝を仕上げる作業が一般的であったが、その作業性を向上させるために二条の畝溝を同時に仕上げることができる管理機として、乗車型の畝跨ぎ式管理機が提供されてきた。
乗車型の畝跨ぎ式管理機の場合、運転席を必要とするため大掛かりな機械構造になると共に、該運転席へ乗車する際に、メインフレーム床まで両足を上げたり、着座のために腰を折るなど、幾度となく体重移動をしなくてはならず、機械コストおよび作業者の乗降に伴う労働負担が大きくなる、といった問題点があった。
Conventionally, when performing field farming work, it was common to finish ridges one by one with a tending machine. Ride-on, ridge straddle type tending machines have been provided.
In the case of a riding-type ridge straddling type tending machine, a large-scale mechanical structure is required because it requires a driver's seat. There was a problem that the machine cost and the labor burden associated with getting on and off the operator increased because the weight had to be shifted many times, such as by folding.
ところで、従来における乗車型の畝跨ぎ式管理機としては、例えば、移植作業時において作業の軽減が図れると共に、一人の作業者によって植え付け作業が行えるようにした「移植機」(特許文献1)が提案され、公知技術となっている。具体的には、畝を跨いで走行する走行体に、畝に苗を植え付ける移植装置が支持されると共に、後部側に操向ハンドルが設けられた乗車式の移植機であって、走行体の後部側に前部が縦軸に枢支された牽引台車が連結され、牽引台車には、畝を跨いで走行する車輪と、操向ハンドルより後方で作業者が乗車する乗車部とを設けた技術提案である。 By the way, as a conventional riding-type ridge straddling type tending machine, for example, there is a "transplanter" (Patent Document 1) that can reduce the work at the time of transplanting work and also allows the planting work to be performed by a single operator. proposed and known in the art. Specifically, it is a riding-type transplanter in which a transplanting device for planting seedlings in the ridge is supported by a traveling body that travels across the ridge, and a steering handle is provided on the rear side, and the traveling body A towing truck whose front part is pivotally supported on a vertical shaft is connected to the rear side, and the towing truck has wheels that run across the ridge and a riding part that a worker gets on behind the steering handle. It is a technical proposal.
しかしながら、かかる「移植機」の提案は、運転席が設けられることで大掛かりな機械構造になっていると共に、乗車に際しメインフレーム床に両足を上げて載せ、さらに腰を折って運転席に乗り込むこととなるため、乗り降りする際に幾度となく体重移動が必要となることから、機械コストおよび作業者の乗降に伴う労働負担の増大という上記問題を解決することにはならない。 However, the proposal of such a "transplant machine" has a large-scale mechanical structure due to the provision of a driver's seat. Therefore, it is necessary to shift the weight many times when getting on and off, which does not solve the above-mentioned problems of an increase in machine cost and the labor burden associated with getting on and off the operator.
かかる乗車型の畝跨ぎ式管理機に代わって、本出願人により、跨いだ畝とその両側の畝の側面を同時に形成できる「歩行型畝跨ぎ高畝形成機」(特許文献2)が提案されている。具体的には、前側の駆動軸支持体には左右外端部に畝高を超える縦長筒状の前脚部を斜め前下方へ突設し、その駆動軸支持体と平行に近接した後側の駆動軸支持体には外端部に畝高を超える縦長筒状の後脚部を下方へ突設し、両前脚部の下部には畝に向けて畝突き板を起伏動させる畝押圧部の回転軸を枢着し、両前脚部の下部の前側に前足部を突設してその前端部に設けた掻上爪を回転させるロータリ部の回転軸を枢着し、両後脚部の下部にはクローラを回転させる回転軸を枢着し、後側の駆動軸支持体の後部には左寄りにエンジンを搭載すると共に右寄りに後方に向けてハンドルを突設し、前側と後側の駆動軸支持体に内蔵した回転駆動軸の中央部にクラッチを備えたトランスミッションを設けて成る、歩行型の畝跨ぎ式管理機の技術提案である。 Instead of such riding-type ridge-straddling type tending machines, the present applicant has proposed a "walking-type ridge-straddling high ridge forming machine" (Patent Document 2) that can simultaneously form straddling ridges and side surfaces of the ridges on both sides thereof. ing. Specifically, on the front drive shaft support, vertically elongated cylindrical front legs exceeding the ridge height are provided at the left and right outer ends so as to protrude obliquely forward and downward. At the outer end of the drive shaft support, a vertically elongated cylindrical rear leg that exceeds the height of the ridge protrudes downward. A rotating shaft is pivotally attached to a rotary portion for rotating a raking claw provided at the front end of the forefoot projecting from the lower portion of both front legs. A rotary shaft that rotates the crawler is pivotally attached to the rear drive shaft support, and the engine is mounted on the left side of the rear drive shaft support, and the handle is protruded toward the rear on the right side, and the front and rear drive shafts This is a technical proposal for a walk-type ridge-straddling tending machine that has a transmission equipped with a clutch at the center of a rotary drive shaft built into a support.
しかしながら、かかる「歩行型畝跨ぎ高畝形成機」の提案は、作業機の自走に伴って作業者が歩くことを強いられることから、やはり作業者の労働負担の増大という上記問題を解決することにはならない。 However, the proposal of such a "walking type ridge straddling high ridge forming machine" solves the above-mentioned problem of increasing the labor burden of the worker because the worker is forced to walk as the work machine self-propelled. It doesn't matter.
本出願人は、畝跨ぎ式管理機おける作業者の作業性向上に着目し、ハンドル操作をした状態で任意に乗り降り可能な歩行型の畝跨ぎ式管理機を提供ができないものかという着想の下、畝跨ぎ式管理機によって牽引されて自走すると共に、ハンドル操作をした状態で任意に乗り降り可能な乗用補助台車を開発し、本発明にかかる「乗用補助台車並びに該乗用補助台車を装着した歩行型畝跨ぎ式管理機」の提案に至るものである。 The applicant of the present invention focused on improving the workability of workers in a ridge-straddling tending machine, and came up with the idea of providing a walking-type ridge-straddling tending machine that can be arbitrarily mounted and dismounted while the handle is being operated. Developed a passenger-assisting trolley that is towed by a ridge straddle type management machine and can be arbitrarily mounted and dismounted while operating the steering wheel. This led to the proposal of the mold ridge straddling type tending machine.

FIG. 2A and 2B are explanatory diagrams showing the use state of the riding auxiliary trolley 10 and the walk-type ridge straddle type tending machine 40 according to the present invention, where (a) is a side view and (b) is a rear view. . Furthermore, FIG. 3 is an explanatory view showing another embodiment of the passenger assistance trolley 10 according to the present invention. 4 and 5 are explanatory diagrams showing other embodiments of the riding auxiliary trolley 10 and the walking type ridge straddling type tending machine 40, respectively, according to the present invention.
本発明にかかる乗用補助台車10は、歩行型畝跨ぎ式管理機40に装着されるものであって、主に踏み台11と、走行輪12と、連結手段15と、で構成されている。
踏み台11は、平板状であって、上面に作業者Mが立ったまま乗ることが可能な形状および大きさを有して形成される。このとき、仮に踏み台11の幅が畝溝Rの幅より幅広であると、畝溝Rを移動する際に踏み台11の側方部分が畝Uに接触し、畝Uを崩してしまったり、歩行型畝跨ぎ式管理機40での牽引時に障害となるおそれが想定される。したがって、踏み台11の幅は、畝溝Rの幅よりも幅狭に形成されるのが好適である。また、踏み台11の下方部には、作業者Mが踏み台11の上に乗った状態で歩行型畝跨ぎ式管理機40に牽引されて移動を可能にするための走行輪12が配置されている。該走行輪12は、一輪乃至複数輪の農作業用の扁平タイヤで構成される。さらに、踏み台11の前方域には、乗用補助台車10を歩行型畝跨ぎ式管理機40と連結するための連結手段15が備えられている。尚、踏み台11の上面には、作業者Mが足を滑らすことのないよう、滑り止め手段が施される態様が好適である。
A riding auxiliary trolley 10 according to the present invention is attached to a walking type ridge straddle type tending machine 40, and is mainly composed of a step 11, a running wheel 12, and a connecting means 15.
The footstool 11 has a flat plate shape and is formed to have a shape and size that allow the worker M to stand on the top surface thereof. At this time, if the width of the footstool 11 is wider than the width of the ridge groove R, the side portion of the footstool 11 contacts the ridge U when moving the ridge groove R, and the ridge U may be broken, or walking may occur. It is assumed that there is a risk of becoming an obstacle when being towed by the mold ridge straddling type tending machine 40 . Therefore, it is preferable that the width of the step 11 is narrower than the width of the ridge groove R. In addition, in the lower part of the step 11, a running wheel 12 is arranged to enable the worker M to move while being towed by the walking type ridge straddle type tending machine 40 while standing on the step 11. . The running wheel 12 is composed of one or more flat tires for agricultural work. Furthermore, a connecting means 15 for connecting the auxiliary trolley 10 to the walking type ridge straddle type tending machine 40 is provided in the front region of the step 11 . In addition, it is preferable that the upper surface of the step 11 is provided with anti-slip means so as to prevent the operator M from slipping.
連結手段15は、乗用補助台車10と歩行型畝跨ぎ式管理機40とを連結するものであって、該歩行型畝跨ぎ式管理機40における後方補助輪41に対し、乗用補助台車10を回動可能に連結し得る態様であれば、その具体的な構造については特に限定するものではないが、例えば図示の様に、連結竿13と枢軸部14で構成されて成る態様が考え得る。連結竿13は、踏み台11から前方へ延伸状に備えられる一乃至二本の棒材もしくはプレート材であって、基端部は踏み台11に固定され、先端部には枢軸部14が回動可能に軸支されている。そして、枢軸部14は、後述する歩行型畝跨ぎ式管理機40における後方補助輪41の側方域に固定されており、例えば後方補助輪41の回転軸部と同軸に固定されたり、あるいは、後方補助輪41のカバー材側壁に固定されている。これにより、連結竿13が枢軸部14を軸に回動可能となり、故に連結竿13に固定された踏み台11が枢軸部14を介して回動可能に構成される。尚、連結竿13の長さについては、踏み台11を回動した際に、歩行型畝跨ぎ式管理機40の後方補助輪41や後述する足掛けステップ43を回避し得るだけの長さを有している。連結竿13が二本備えられる場合には、踏み台11から前方へ後方補助輪41を両側から挟むように延伸して備えられる。 The connection means 15 connects the riding auxiliary trolley 10 and the walking type ridge straddle type tending machine 40 , and rotates the riding auxiliary trolley 10 with respect to the rear auxiliary wheels 41 of the walking type ridge straddling type tending machine 40 . The specific structure is not particularly limited as long as it can be connected movably. The connecting rod 13 is one or two rods or plates extending forward from the step 11, and has a base end fixed to the step 11 and a pivot portion 14 rotatable at the tip. pivoted on. The pivot portion 14 is fixed to the side region of the rear auxiliary wheel 41 in the walking type ridge straddle type tending machine 40 described later, for example, fixed coaxially with the rotation shaft portion of the rear auxiliary wheel 41, or It is fixed to the cover material side wall of the rear auxiliary wheel 41 . As a result, the connecting rod 13 is rotatable about the pivot portion 14 , and therefore the step stool 11 fixed to the connecting rod 13 is configured to be rotatable via the pivot portion 14 . The length of the connecting rod 13 is long enough to avoid the rear auxiliary wheel 41 of the walking type ridge straddling type tending machine 40 and the footrest step 43 to be described later when the step 11 is rotated. ing. When two connecting rods 13 are provided, they are provided so as to extend forward from the step 11 so as to sandwich the rear auxiliary wheels 41 from both sides.
作業者Mは、踏み台11の後方域を手で掴んで上下に回動することとなる。そこで、図3に示す様に、踏み台11の後方に把持部16を形成する態様が好適である。該把持部16は、図示の様に、踏み台11の後方域を長楕円状にくり抜いて形成する態様のほか、図示していないが、丸棒をコの字状に屈曲して踏み台11の後端辺に溶接等で固定する態様や、踏み台11の後方域における上面及び下面に凹凸状の滑り止め加工を施す態様などが考え得る。
このように、踏み台11の後方に把持部16を設けることで、踏み台11の取り出し並びに格納時の回動作業を容易にすると共に、手が滑って踏み台11が滑落する危険を回避することができる。
The operator M grips the rear region of the step 11 by hand and rotates it up and down. Therefore, as shown in FIG. 3, it is preferable to form a grip portion 16 behind the footboard 11 . As shown in the figure, the grip part 16 is formed by hollowing out the rear region of the footboard 11 into an oblong shape, or, although not shown, is formed by bending a round bar into a U-shape to form the rear part of the footboard 11. It is possible to conceive a mode in which the edge is fixed by welding or the like, and a mode in which the upper and lower surfaces of the rear region of the footstool 11 are provided with uneven non-slip processing.
By providing the gripping portion 16 at the rear of the step 11 in this way, it is possible to easily rotate the step 11 at the time of taking out and storing the step 11 and avoid the risk of the step 11 slipping down due to a slip of the hand. .
以上の構成から成る本発明にかかる乗用補助台車10は、歩行型畝跨ぎ式管理機40に装着される。
乗用補助台車10が装着される歩行型畝跨ぎ式管理機40は、例えば、特許文献2に示すような「歩行型畝跨ぎ高畝形成機」であって、クラッチを備えたトランスミッションを介してエンジンの回転を左右に振り分けて伝達する前側と後側の回転駆動軸を前後平行に内蔵して夫々支持する前側と後側の駆動軸支持体のうち、前側の左右の駆動軸支持体には、夫々の外端部に畝高を超える縦長筒状の前脚部を斜め前下方へ突設し、後側の左右の駆動軸支持体には、夫々の外端部に畝高を超える縦長筒状の後脚部を下方へ突設し、左右の前脚部の下部には、左右両側を畝側面に向けて逆V字形に傾斜させた両側の畝突き板を掻上げらたれた土を押圧するように起伏動させる畝押圧部の回転軸を枢着し、該両前脚部の下部の前側に前足部を突設して該前足部の前端部に設けた畝溝Rの土を畝側面に掻上げる両側の掻上爪を回転させるロータリ部の回転軸を枢着すると共に両前脚部及び両前足部内には前側の回転駆動軸の回転を畝押圧部及びロータリ部の回転軸へ伝達させる回転伝達部材を装着し、左右の後脚部の下部には、夫々走行輪又はクローラを回転させる回転軸を枢着すると共に両後脚部内には後側の回転駆動軸の回転を走行輪又はクローラの回転軸へ伝達させる回転伝達部材を装着し、後側の駆動軸支持体の後部には、エンジンを搭載すると共に左右いずれか一方寄りには後方に向けてハンドル操作部45を突設して構成される。
