Rotary planting equipment of rice transplanter

摘要

PROBLEM TO BE SOLVED: To smoothly perform a high-speed planting by standardizing rotational resistance of a rotary case in a rotary type rice transplanter having two planting bodies fitted to the rotary case.;SOLUTION: A rotary case 7, in the inside thereof, is disposed with a sun gear 14, intermediate gears 15, and planetary gears 16. Each planetary gear 16 includes a backlash-removing peripheral cam 28 defining one part of the outer peripheral face as a peak farthest from the axial center. A lever 29 is brought into contact with the backlash-removing peripheral cam 28 and is energized by a spring 30. The respective intermediate gears 15 are configured into irregular velocity gears, with the intermediate shafts 23 pivotally supporting them decentered. The intermediate shafts 23 are held inside the rotary case 7 via intermediate bearings 24.;COPYRIGHT: (C)2014,JPO&INPIT
