  Therefore, even if it is a long pile, by adjusting the height position of the strut part 30, the striking part 20 can be lowered from a high position by adjusting the height position of the striking part 20, Can be driven easily.

As described above, according to the pile driving machine 10 shown in FIG. 1, the connecting portion 60 provided in the column inclined portion 50 is attached to the arm A1 and the arm cylinder A2 of the heavy machine M. By extending and contracting, the inclination of the pile driving machine 10 in the front-rear direction can be adjusted. Moreover, since the support | pillar support part 40 which supports the support | pillar part 30 is connected with the support | pillar inclination part 50, since the pile driving machine 10 can be made into various inclinations in the left-right direction, even if it is an inclined land, it is also an inclined land. On the other hand, even if the direction of the heavy machine M is directed in various directions, the pile can be driven perpendicularly to the inclined ground.
Therefore, the pile driving machine 10 can efficiently perform pile driving with various inclinations.

In the present embodiment, the column inclined portion 50 is formed by the rotary cylinder including the shaft portion 51 and the rotation driving unit 52. However, the column inclined portion extends forwardly connected to the column supporting portion. A shaft part, a disk part in which the shaft part is arranged at the center of rotation, and a cylinder having a piston rod connected to an eccentric position of the disk part may be provided.
By configuring the column inclined portion in this way, when the piston rod of the cylinder is advanced and retracted, the disk portion connected to the position where the piston rod is eccentric rotates, so that the shaft portion can be rotated. Therefore, the linear motion of the cylinder, which is the drive portion, can be converted into a rotational motion by the disk portion, and the column support portion can be inclined in the left-right direction by the shaft portion.

  The pile driving machine of the present invention is suitable for pile driving on a slope because pile driving with various inclinations is possible not only in the front-rear direction but also in the left-right direction.
