[0001]

BACKGROUND OF THE INVENTION The present invention relates to a multi-row type seedling plant, more specifically, a float plant, which is equipped with a float sensor, and controls a lifting device based on a detection result from the float sensor to adjust the planting depth. The present invention relates to a seedling transplanter.

[0002]

2. Description of the Related Art Conventionally, this seedling planter is provided with a planting claw.
A planting device having a plurality of planting portions and a plurality of floats is supported on the traveling body side via a lifting device so as to be able to move up and down, and the lifting device is based on a detection result from a float sensor.
Controlled by have Dzu, and to adjust the planting depth of the seedling by the respective planting unit to a predetermined depth by vertically lifting the whole of the planting device. Further, in a multi-row type seedling planting machine, a pair of float sensors configured to enable a pair of floats located on the left and right with respect to the center in the width direction of the body to be able to move up and down and individually detect the operation angles thereof. Is provided, and by controlling the elevating device based on the average value detected by each of the float sensors, the planting depth of each of the planting sections is accurately adjusted. Further, in the above seedling transplanter, the float sensor detects the operation angle of the float using a plurality of links. If you want to change the difference between the set value, in other words, when changing the setting angle of the float, to form a plurality of adjustment holes for adjusting one setting angle of the float to the interlocking part of the link, connecting the link The set angle of the float , that is, the set value of the planting depth of the seedlings is changed by selectively replacing the pin to be set with one of the adjustment holes, and the float sensor is set through the float sensors based on the set value. Thus, the raising and lowering device is controlled to adjust the planting depth of the seedlings by each planting section.

[0003]

However, in the above seedling plant, when the set value of the planting depth of the seedling by each planting part is changed, the adjusting hole of the link in each float sensor is provided. When the pins need to be selectively replaced, and the replacement operation of the pins with respect to the adjustment holes is required to be performed for each of the float sensors when the float sensors are provided in a pair of right and left, the replacement of the planting depth is required. There was a problem that the operability when changing the set value was poor.

The present invention has been made in view of the above problems, and has as its object to provide a seedling planting machine which can change the set value of the planting depth of a seedling by each planting section by a simple operation. Is to do.
