Description
【考案の詳細な説明】 〔産業上の利用分野〕 本考案は、前輪及び該前輪より左右幅を大に設定して
ある後輪を夫々駆動可能に備えた走行車体の後方に作業
装置を連結してある水田用の作業機に関する。[Detailed description of the invention] [Industrial application field] In the invention, a working device is connected to the rear of a traveling vehicle body that is provided with a front wheel and a rear wheel that is set to be wider left and right than the front wheel so as to be driven. Related to a working machine for paddy fields.
冒記の作業機では後方に連結した作業装置により機体
全体の重心も後方に移動し、前輪の接地荷重が小さくな
って、推力が低下する。そこで一般には、機体前部にバ
ランスウエイトを取り付けることで機体全体の重心を機
体前方に移動させている。In the working machine described at the outset, the center of gravity of the entire body also moves rearward due to the working device connected rearward, the ground contact load of the front wheels decreases, and the thrust decreases. Therefore, in general, the center of gravity of the entire aircraft is moved forward by attaching a balance weight to the front of the aircraft.
しかし上記従来の構成では、別途バランスウエイトを
機体に取り付けるため、機体全体の重量を大きくしてし
まい、水田用作業機に要求される軽量化を損なってしま
う。However, in the above-described conventional configuration, since the balance weight is separately attached to the body, the weight of the entire body is increased, and the weight reduction required for the paddy field working machine is impaired.
本考案は上記実情に鑑みなされたもので、機体重量を
大きくすることなく前輪及び後輪から十分な推進力を発
生できる水田用の作業機を提供するものである。The present invention has been made in view of the above circumstances, and provides a working machine for a paddy field that can generate sufficient propulsion from the front wheels and the rear wheels without increasing the body weight.
本考案にかかる水田用の作業機は、前輪及び該前輪よ

た走行車体の後方に作業装置を連結してある水田用の作
業機において、前記後輪に接地点で半径方向外側ほど回
転方向の上手側に位置する接地面となるように前記後輪

とともに、前輪に接地点で半径方向外側ほど回転方向の
下手側に位置する接地面となるように前記前輪の前進回
転方向に対するくい込み角を持ったラグを備えてあるこ
とを特徴構成とする。The working machine for a paddy field according to the present invention is a paddy field working machine in which a working device is connected to a rear side of a traveling vehicle body that is provided with a front wheel and a rear wheel having a left and right width set larger than the front wheel so as to be drivable. The rear wheel is provided with a lug having a staggered angle with respect to the forward rotation direction of the rear wheel so that the rear wheel has a contact surface with respect to the forward rotation direction such that a radially outer side of the rear wheel is located on the upper side in the direction of rotation in the radial direction. And a lug having a cut-in angle with respect to the forward rotation direction of the front wheel is provided so that the outer side in the radial direction becomes a ground contact surface located on the lower side in the rotation direction.
本考案の構成によると、機体前進時には、後輪に備え
たおくれ角を持ったラグが、その接地面で地面を下方に
押すことによってこの後輪に浮力を発生させるととも
に、駆動反力等で前輪が浮き上がる力を前輪に備えたく
い込み角を持ったラグが、この前輪を接地する地面側に
くい込み作用させることによりこの前輪の浮き上がりを
押さえる。又、このくい込み作用により接地面を荒らす
虞れがあるものの、前輪の左右幅は後輪に比較して小さ
いものであるので、比較的軽度の荒れで済む。一方、お
くれ角を持ったラグでは地面を押さえるようにラグが作
用するとともに左右幅が広幅であるため地面を荒らす可
能性が小さいものになっている。According to the configuration of the present invention, when the fuselage moves forward, the lug having a stagger angle provided on the rear wheel generates buoyancy on the rear wheel by pushing the ground downward on the ground contact surface, and also generates a driving reaction force and the like. A lug having a wedging angle that provides the front wheel with a force to lift the front wheel suppresses the front wheel from rising by making the front wheel dig into the ground side where it touches the ground. Further, although there is a possibility that the grounding surface may be roughened by the digging action, the front and rear widths of the front wheels are smaller than those of the rear wheels. On the other hand, in the case of a lag having a staggered angle, the lug acts so as to press the ground, and the lateral width is wide, so that the possibility of roughening the ground is small.
従って、本考案によると、機体前後にバランスウエイ

体の軽量化を可能にして、ラグ構造と相まってそれによ

きた。Therefore, according to the present invention, the front wheels and the rear wheels can generate a sufficient propulsion force without increasing the weight of the body by attaching balance weights to the front and rear of the body, enabling the weight of the body to be reduced. Coupled with the rug structure, it was possible to improve the running ability in a state where the field scene was relatively difficult to be roughened.
以下、本考案の実施例を図面に基づいて説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
