この発明は、走行車体の後部に苗植付袋@を昇降自在に
連結した乗用田植機に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a riding rice transplanter in which a seedling planting bag is connected to the rear of a traveling vehicle body so as to be movable up and down.
近年の乗用田植機においては、苗植付装置に備えたセン

ッチングに拘わらず植付深さを安定させるように構成し
ている。In recent years, riding rice transplanters have been designed to automatically raise and lower the seedling planting device to maintain the ground pressure of the sensor float installed in the seedling planting device at a set value, regardless of unevenness of the tiller or pitching of the vehicle body. The structure is designed to stabilize the planting depth.
又、圃場の条件に対応してセンサーフロートの感知特性
を調節できるように構成さ″れている。Furthermore, the structure is such that the sensing characteristics of the sensor float can be adjusted in accordance with field conditions.
しかし、圃場の微妙な条件変動に対してセンサーフロー

、フロートによる泥押しが多くなることもある。However, the sensing characteristics of the sensor floats cannot be adequately adapted to subtle changes in field conditions, and sometimes the elevation control is not performed properly, resulting in fluctuations in planting depth and mud pushing by the floats. There may be more.
又、このような問題の発生を抑制する手段として、セン
サーフロートの前方に整地板を配備して、センサーフロ

た。In addition, as a means of suppressing the occurrence of such problems, it has been considered to install a leveling plate in front of the sensor float to reduce the unevenness of the field surface on which the sensor float acts, but this leveling plate It was difficult to set up the sensor float to properly level the ground, and incorrect settings could actually have a negative effect on the operation of the sensor float.
本発明は、上記整地板を導入する際の問題を解消するこ
と全目的とする。The entire purpose of the present invention is to eliminate the problems in introducing the above-mentioned leveling plates.
そこで、本発明においては、センサーフロートの前方に
角度調節自在な整地板を配設するとともに、この整地板

地圧を設定値に維持するように整地板の角度を駆動制御
する手段を備えた構成とした。Therefore, in the present invention, a ground leveling plate whose angle can be adjusted freely is disposed in front of the sensor float, and a pressure sensor is provided to detect the ground pressure acting on this ground leveling plate, and the ground pressure is maintained at a set value. The structure is equipped with a means to drive and control the angle of the ground leveling plate.
〔作 用]
上記構成によると、センサーフロートの前方は整地板に
よって軽く均らされるのであるが、整地板が深く沈んだ
り、硬い隆起部に作用したりして接地圧が大きくなると
整地板の角度(田面とのなす角度)がゆるくなるように
自動調節され、整地板の沈下による泥押しを少くしたり
、硬い隆起部の無理な押しつぶしが行われる。[Function] According to the above configuration, the area in front of the sensor float is lightly leveled by the ground leveling plate, but if the ground leveling plate sinks deeply or acts on a hard raised part and the ground pressure increases, the ground leveling plate will become flat. The angle (the angle it makes with the rice field) is automatically adjusted to make it gentler, reducing the amount of mud pushed due to the subsidence of the leveling plate, and forcing hard ridges to be crushed.
従って、本発明によれば、センサーフロートが作用する
圃場面が整地板によって適切に均らされることになり、
センサーフロートの作動が安定して植付は深さの安定化
を図るとともに、フロートによる不当な泥押しを防止で
きるようになった。Therefore, according to the present invention, the field area on which the sensor float acts is appropriately leveled by the leveling plate,
The stable operation of the sensor float has made it possible to stabilize the planting depth and prevent undue mud pushing by the float.

される。FIG. 1 shows the rear part of the riding rice transplanter according to the present invention.
This rice transplanter has a seedling planting device (4) connected to the rear of a passenger vehicle body (1) via an elevating link mechanism (3) driven by a hydraulic cylinder (2). The attachment device (4) is automatically controlled to raise and lower by known means based on ground pressure fluctuations of a sensor float (5) provided at its lower part.

されている。As shown in FIG. 2, the sensor float (5) is pivotably supported vertically around a rear fulcrum (a), and the front part of this sensor float (5) and the hydraulic cylinder (2) ) is mechanically linked to the control valve (6) of the sensor float (5), and when the ground pressure acting on the sensor float (5) deviates from the set value and the sensor float (4) moves up or down, the seedling planting device (4) is controlled to move up and down in the same direction as the float displacement direction, and the ground pressure of the sensor float (5) is maintained at the set value (including the dead zone), thereby causing the planting device (
The level of 4) against rice fields has been stabilized. In addition, the seedling planting device (4) is equipped with a sensor float (
In addition to 5), there are floats for leveling the ground, but they are omitted in the figure.
以上の構成は特に従来と変わるところはなく、本発明に
おいては、更に次のような構造が追加されている。The above configuration is not particularly different from the conventional one, and the following structure is further added in the present invention.

ンサ(8)によって検出されるようになっている。In other words, a leveling plate (7) for leveling the ground in front of the sensor float (5) is provided at the bottom of the lifting link mechanism (3). This leveling plate (7) swings around the fulcrum γ. A pressure sensor (8) is disposed opposite to an arm (7a) that is movably supported and extends upward from a fulcrum (Y), and the ground pressure acting on the lower part of the ground leveling plate (7) is applied to the sensor (8). ).
又、この整地板(7)及び圧力センサ(8)ヲ支えた枠
体(9)が、前記支点(Y)周りに減速機付きモータQ
Oによって駆動回転調節可能に構成されていて、枠体(
9)の回動によって整地板(7)の角度が変更できるよ
うになっている。In addition, the frame body (9) supporting the ground leveling plate (7) and the pressure sensor (8) supports the motor Q with a reducer around the fulcrum (Y).
The drive rotation can be adjusted by O, and the frame (
The angle of the ground leveling plate (7) can be changed by rotating 9).
そして、このモータαQは前記圧力センサ(8)の検出
圧力が設定値(不感帯全台む)になるように制御されて

面に対して起立する方向に角度調節されるのである。This motor αQ is controlled so that the pressure detected by the pressure sensor (8) becomes a set value (all dead zones are included). Therefore, for example, when the ground pressure becomes larger than the set value, the angle of the ground leveling plate (7) is adjusted so as to increase the forward inclination with respect to the field surface, and conversely, when the ground pressure becomes smaller than the set value, the ground leveling plate (7) is adjusted in the direction of standing up against the field surface. The angle is adjusted accordingly.
尚、整地板(7)の角度を調節する駆動機構としてはモ
