DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a planting main body, which is a case body 3 having an opening 2 whose top is open from the tip to the middle, and the opening 2
And a lid 4 for covering the inside of which a cavity 5 is formed. A base portion is rotatably attached to a tip end of a rocking body 6 by a support shaft 7, and a downward seedling division body 8 is attached to the tip end. It is fixed.

Reference numeral 9 denotes a seedling extruding body, which is slidably provided at the tip of the planting main body 1 so that an extruding element 10 provided at the lower end of the seedling extruding body moves up and down along the seedling dividing body 8. Reference numeral 11 denotes a crank shaft having a crank shape, which is inserted into an intermediate portion of the planting main body 1 and is swung by a drive shaft 13 which is supported by a machine body 12 and driven. Is stuck. In addition, the cavity 5 of the planting main body 1
A pair of U-shaped bearing grooves 15 with an open top are provided on the inner wall of the
・ 15 is directly provided facing each other on the left and right, and the extrusion actuator 1
Both ends of a shaft 17 integrally provided in the middle part of 6 are supported, and the tip end and the base end of this extrusion actuating body 16 are engaged with the upper part of the seedling extruding body 9 and the cam 14, respectively. The lid 4 is fixed on the upper part of the lid 4, and the lower end of the spring 18 fixed to the inner surface of the lid 4 presses the tip end side of the shaft 17 of the push-out actuator 16 so that both ends of the shaft 17 are U-shaped bearings. Groove 15
It is pressed against the bottom end of 15.

In the figure, 19 is a seedling stand, 20 is a float, and 21 is a rotating shaft. Since the seedling planting device in this seedling planting machine is configured as described above, when the drive shaft 13 rotates, the planting main body 1 is swung by the crankshaft 11, but the base of the planting main body 1 is rotated. The pivot shaft 2 is pivotally attached to the tip of the rocking body 6 pivotally attached to the machine body 12 by the moving shaft 21.
Since it swings around 1, the seedling-divided body 8 at the tip thereof makes a deformed oval movement. Then, the rotation of the crankshaft 11 causes the cam 14 to rotate with respect to the planted main body 1 to cause the pushing operation member 16 to move.
Since the base part of the seedling is moved up and down, the tip end thereof is vertically moved around the shaft 17 to move the seedling extruding body 9 up and down.
0 is at the upper limit when the seedling dividing body 8 is on the upper side, and in this state, it projects to the seedling mounting table 17 and scrapes one seedling,
