Abstract
PURPOSE: To control the speed shifting operation of a belt converter and a transmission for a moving vehicle body appropriate to a rice planter in particular and simplify an operation mechanism, by operating a single speed-shifting lever which can be moved forward, backward, rightward and leftward.
CONSTITUTION: A speed shifting lever 13 is swung rightward or leftward to change a transmission 12 so that a moving vehicle body 1 which runs rapidly on a road is shifted to a low speed to plant rice seedlings in a field. To shift the moving vehicle body 1 to a speed lower than the planting speed to set a proper spacing for the next planting travel after the turning of a planter, the lever 13 is swung forward or backward to rotate a rotary valve to supply pressurized oil to a hydraulic cylinder 20 by a pump so that a piston rod 21 is driven outward and a belt 16 is tightened through a tension arm 17 and a roller 18 and moved in contact with the small- diameter part of a torque conversion pulley 15 for an engine 4. At that time, the rotation of an input shaft 14 is retarded to decrease the speed of the moving vehicle body 1.
