    • PROBLEM TO BE SOLVED: To facilitate shift-operation of traveling speed of a riding type rice transplanter comprising a traveling machine body 2 having traveling wheels 5, 6 to be driven by an engine 7, a seeding planting device 3 installed at the rear part, a traveling transmission 8 for the traveling wheels, and a gear shift pedal 12 installed at an operation control part 9 of the traveling machine body. SOLUTION: A traveling operation device comprises an actuator 28 for shift-operating the traveling transmission, and a detection means 24 for detecting the depressing operation and the releasing operation of the gear shift pedal. The actuator 28 operates the traveling transmission to increase a speed when the detection means detects the depressing operation of the gear shift pedal, and operates the traveling transmission to reduce a speed when the detection means detects the releasing operation of the gear shift pedal.

    • PURPOSE:To improve the turning and backward moving properties of a ride-type rice planter body, by shifting a control valve to alternately move sleighlike ground contact members and wheels in and out and effecting alternate ground contact to move a seedling planting unit up and down. CONSTITUTION:Sleigh-like ground contact members 8 and wheels 12 are alternately moved in and out by link mechanisms C. A driving-side member 17 and a mounting member 18 are engaged with each other by a movable engaging member (b) to determine the positonal relationship between the wheel 12 and the ground contact member 8. An interlock release mechanism A acts to the movable engaging member (b) and is operated by an interlock operation mechanism D made of a cam mechanism 23. On the way of the elevation of the wheels 12 by the action of a driver 14, the interlock operation mechanism D acts to release the interlock of the link mechanism C. For that reason, the ground contact members 8 can move down even after the contact of the wheels 12 with stoppers 21, and the housing space for the after the contact of the wheels 12 with stoppers 21, and the housing space for the wheels 12 can be reduced. The wheels 12 are selectively put ont the ground to improve not only the movement on the road but also the turning on the field.
    • 目的:为了提高搭乘式米饭播种机的转向和向后移动性能,通过移动控制阀,将雪橇式地面接触构件和轮子交替移动并移出,并进行交替地面接触,使秧苗种植单元上下移动 。 构成:雪橇状地面接触构件8和车轮12通过连杆机构C交替地移入和移出。驱动侧构件17和安装构件18通过可动接合构件(b)彼此接合,以确定 轮12与接地构件8之间的正负的关系。联动释放机构A作用于可动接合构件(b),并由由凸轮机构23制成的互锁操作机构D操作。 轮12通过驱动器14的作用,联锁操作机构D用于释放连杆机构C的互锁。因此,即使在车轮12与止动件21接触之后,地面接触件8也可以向下移动 并且可以减少用于具有止动件21的轮12接触之后的容纳空间以及用于车轮12的容纳空间。 车轮12选择性地放在地面上,不仅改善了道路上的运动,而且改善了场地的转弯。
