Abstract

The subject of the invention is to prevent rice seedling empty planting in automatic elevating control of turning. The transplanter (1) is provided with a planting part (3) which can rise up and down; a planting clutch (50) which disconnects and connects drive force transmitted to the planting part (3); a control part which automatically performs elevating control for turning to control the rising and descending of the planting part (3) in turning of a vehicle and the planting clutch (50). In automatic elevating control of turning, the control part automatically lowers the planting part (3) at a prescribed correct time in turning or after turning. In addition, when the vehicle arrives at a plant restart position corresponding with a plant interruption position before turning, the control part connects the clutch (50) and starts planting again. In addition, the control part corrects the descending time of the planting part (3) according to driving speed change of the vehicle.

Description

technical field [0001] The present invention mainly relates to the control of automatically raising and lowering the planting part when the vehicle body of the rice transplanter is turned. Background technique [0002] The rice transplanter is equipped with a planting unit (rice transplanting device) for planting rice seedlings. If the vehicle body is turned with the planting portion approaching or in contact with the ground, the planting portion may come into contact with the ground or a ridge and be damaged. Therefore, there is known a rice transplanter having a structure in which a planting part is automatically raised when the vehicle body is turned. Such a rice transplanter is described in patent document 1, for example.
