Title:
RIDING-TYPE RICE PLANTING MACHINE
Document Type and Number:
WIPO Patent Application WO/2015/170652
Kind Code:
A1
Abstract:
Provided is a riding-type rice planting machine that, on the basis of the height (paddy surface height) from a paddy surface unrelated to the sink amount of a float to a predetermined position of a planting unit, controls the vertical position adjustment of a soil preparation device appropriately, thereby favorably ensuring good soil preparation accuracy of the soil preparation device. The riding-type rice planting machine is provided with a paddy surface height detection means for detecting a paddy surface height that is the height from a predetermined position of the planting unit to the paddy surface, and a control means for connecting the paddy surface height detection means to an input side and connecting a vertical position adjustment means to an output side. The control means acquires the detected values of the paddy surface height detected by the paddy surface height detection means, controls the vertical position adjustment means on the basis of such detected values, and adjusts the soil preparation height of the ground preparation device.
