御性能の向上を図らんとする点にある。[Detailed Description of the Invention] The present invention has one running wheel and a driving part that can be raised and lowered in a side view and a plan view, and the wheels are automatically moved based on the detection result of a ground pressure detector. The rear body, which has a planting device with a float and a driver's seat, is connected to the front body, which is equipped with a mechanism for automatically raising and lowering the plant, and the rear body, which is equipped with a planting device with a float and a driver's seat, can swing left and right around the vertical axis. By automatically driving the wheels up and down based on the system, the swinging attitude of the entire machine relative to the ground around the float contact area can be maintained almost constant regardless of changes in the depth of the plow, thereby stabilizing the planting and riding postures. In addition, regarding a single-wheel riding rice transplanter that is configured to be steered by relative left and right rocking of the front and rear bodies around the vertical axis, the purpose is to improve the ground pressure detection device by simply arranging the ground pressure detection device. In addition to improving detection sensitivity, despite the single-wheel type that can easily roll left and right, this control system suppresses malfunction of the detection tool due to body rolling as much as possible, and stabilizes the planting and riding postures. The point is to try to improve performance.

る。 First, an embodiment of the present invention will be described based on the drawings.In side view and plan view, a front fuselage 5 has a running wheel 1 and a driving unit 2, which are one and can swing freely around the front part as a fulcrum. , a rear body 9 equipped with a four-row planting device 7 with a float 6 and a driver's seat 8 is connected so as to be swingable from side to side around the vertical axis a passing near the axle axis X of the wheel 1. 1 and a float 6, and is configured to be steered by the left and right rocking of the front body 5 relative to the rear body 8, and detects the ground pressure that changes as the depth of the plow changes. In a single-wheel riding rice transplanter, the front body 5 is equipped with a mechanism 4 that automatically raises and lowers the wheel 1 based on the detection result of the detector 3 so that the ground pressure is maintained within a set range. The ground pressure detector 3 is mounted on the front fuselage 5 at a location immediately in front of the wheels 1.

３に連係させて構成してある。 The automatic drive lifting mechanism 4 is provided with a hydraulic cylinder 11 for driving and swinging up and down a wheel support frame 10 which also serves as a transmission case and which supports the wheels 1 on the front body 5 so as to be able to swing up and down. A control valve 12 for the cylinder 11 is connected to the ground pressure detector 3.

特徴とする。 In summary, in the single-wheel riding rice transplanter according to the present invention, as explained at the beginning, when the entire machine body swings vertically around the float contact area as the depth of the tiller changes, the machine body undergoes the largest vertical displacement. It is characterized in that the ground pressure detector 3 is disposed in front of the wheels 1 where the amount of vertical displacement during rolling is extremely small and is attached to the front body 5.

つて植付け姿勢および乗用姿勢を安定化するため
の自動制御性能の向上を図り得るに至つた。 This makes it possible to increase the detection sensitivity of the ground pressure detector 3 against vertical vibrations around the float contact portion of the entire machine body due to changes in the depth of the plowing ground, and also to increase the detection sensitivity of the ground pressure detector 3 against vertical vibrations around the float contact area of the entire machine body due to changes in the depth of the plowing ground. Since the malfunction of the detection device can be minimized, the automatic control performance for stabilizing the planting posture and riding posture can be improved by making a simple improvement such as placing the ground pressure detection device 3 in front of the wheels. I ended up getting it.
しかも、前記接地圧検出具３は、前部機体５に
取付けてあるから、ハンドル操作方向の先を検出
することができ、走行する所を確実に検出するこ
とができる。 Moreover, since the ground pressure detector 3 is attached to the front body 5, it can detect the direction in which the handle is operated, and the place where the vehicle is traveling can be reliably detected.
