この発明は、乗用車体の後部にリンク機構を介して田植
作業を昇降μF能に連結装着してなる乗用型田植機に関
するものである。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a riding type rice transplanter which is connected to the rear part of a passenger vehicle body via a link mechanism to have a μF function for raising and lowering rice transplanting operations.
従来の乗用型田植機では、ローリング0「能に田植作業
機を取付けたもの及びピッチング可能に田植作業、機を
取付けたものはあり、更に、特開昭51−129716
号公報に見られるように、田植作業機を左右一対の」一
部リンクで取付けるとき、その両リンク部分に伸縮可動
部を設けて、田植作業機の取付はガタ分だけはねじれ得
るように設けたものは公知であった。また、実公昭47
−12505号公報で見られる通り、走行車体1の後部
ヒツチに、ローリング軸とピッチング軸とを設けて田植
作業機を装着するものがあった。Among the conventional riding rice transplanters, there are those that have a rice transplanting machine attached to a rolling zero function and those that have a pitching machine that can perform rice transplanting operations.
As seen in the publication, when a rice transplanter is installed with a pair of left and right partial links, both links are provided with telescopic movable parts, so that the rice transplanter can be installed so that it can be twisted by the amount of play. What was known was publicly known. Also, Jikko 47
As seen in Japanese Patent Publication No. 12505, there was one in which a rolling shaft and a pitching shaft were provided on the rear hitch of the traveling vehicle body 1, and a rice transplanting machine was attached thereto.
しかし、これらの従来型のものは、必ずローリング機構
の後にピッチング機構が設けられる構成であったため、
走行車体が前後に振動する場合どうしてもローリング軸
部を介してそのピッチングが行われることになる。この
場合、左右の耕盤変動によって田植作業機側がローリン
グする場合田植作業機側の前後方向の姿勢が未だ修正さ
れていない状態のままでローリングが行われることとな
りローリング機能が充分に発揮されず、下部に装着する
フロートが泥押しする欠点があった。However, these conventional types always had a pitching mechanism installed after the rolling mechanism, so
When the vehicle body vibrates back and forth, pitching inevitably occurs through the rolling shaft. In this case, if the rice transplanter rolls due to left and right movement of the tiller, the rice transplanter's longitudinal posture will continue to be uncorrected and the rolling function will not be fully utilized. There was a drawback that the float attached to the bottom pushed mud.
この発明は、上記課題を解決すべく次の技術手段を用い
たものである。This invention uses the following technical means to solve the above problems.
即ち、乗用車体1の後部にリンク機構18を介して植付
装置16・苗タンク15・フロート17等を有した田植
作業機13をピッチング及びローリング自在に装着した
乗用型田植機において、ピッチング機構23をローリン
グ機1NIt30よりも機体前方側に設けたことを特徴
とする乗用型田植機としたものである。That is, in a riding rice transplanter in which a rice transplanting machine 13 having a planting device 16, a seedling tank 15, a float 17, etc. is attached to the rear of a passenger vehicle body 1 via a link mechanism 18 so as to be capable of pitching and rolling, the pitching mechanism 23 This riding-type rice transplanter is characterized in that it is installed on the front side of the machine body rather than the rolling machine 1NIt30.
乗用車体1が左右に傾動すると共に前後にも傾動するよ
うなときに、前後の傾動はLB植作業機13側に諸々の
悪影響を及ぼすが、この発明は上記の構成としたから、
該乗用車体1の前後傾動がピッチング機構23にて先ず
補正されて口J植作業機13側の前後傾動が非常に少な
くなるので、フロートで受けられる接地力の前後変化が
あまりなく的確にローリング機能が発揮でき泥押しを起
さず良好な苗植付は作業が行えるという作用効果を奏す
る。When the passenger vehicle body 1 tilts from side to side as well as from front to back, the back and forth tilting has various negative effects on the LB planting machine 13, but since this invention has the above configuration,
The longitudinal tilting of the passenger vehicle body 1 is first corrected by the pitching mechanism 23, and the longitudinal tilting of the J-planting machine 13 side is extremely reduced, so that there is not much longitudinal variation in the ground contact force received by the float, and an accurate rolling function is achieved. This has the effect of allowing good seedling planting to be carried out without muddying.

起さず良好な苗植付は作業が行える。When planting seedlings with the riding-type rice transplanter configured in this way, if the tiller is tilted in the front-back direction or has unevenness during the work, the passenger vehicle body 1 side will tilt back and forth. In this case, since the pitching mechanism 23 is located in front of the rolling mechanism 30, the longitudinal tilting is quickly absorbed and corrected in this part, so that it does not affect the rice transplanting machine 13 side. Float 17 is the second
As shown in Figure 3, its posture is not disturbed (the front part does not float or the rear part sinks below the soil surface), and it can maintain its normal posture. For this reason, the rice transplanting machine 13 side is always accurately supported by the float 17, and when the tiller is tilted in the left-right direction, there are irregularities, and the vehicle body 1 is tilted left and right at the same time as the above-mentioned tilt in the front-rear direction. The rolling function can be performed accurately even when the seedlings are planted, and seedlings can be planted without muddying.
