つた。Conventional excavators have an arm that protrudes from the vehicle body, and a packet for excavating dirt is attached to the tip of this arm, but with this configuration, when transferring the excavated soil to the rear of the vehicle, the arm and packet protrude from the side of the vehicle. There was a risk of the machine jumping out and hitting people standing nearby, and the work area had to be widened. For this reason, a swivel platform and a workbench were installed on the vehicle body with their rotational axes eccentric, and the packet was configured to pass above the vehicle body so that the arm and packet would not protrude too far from the side of the vehicle body. An excavator is proposed. However, with this new excavator, both the swivel platform and the work platform must be rotated in a predetermined direction, and if these rotations are not synchronized, the packet will not pass over the vehicle body reliably, and the swivel mechanism is complicated. It had to be (9'1).

回台１４の旋回方向とは逆方向に回転することになる。When hydraulic pressure is supplied to the hydraulic motor 18, the output shaft 36 rotates, the pinion 37 rolls on the external tooth surface of the drive external gear 33, and the slider 35 is rotated along the inner circumference of the drive external gear 33. Accordingly, the swivel base 14 fixed to the slider 35 rotates about the central axis of the drive external gear 33. When the swivel base 14 rotates, the intermediate shaft 41 is rotatably supported on the swivel base 14, so the pinion 42 is rolled along the external tooth surface of the drive external gear 33, and the pinion 42. Intermediate shaft 41 and connected binion 4
6 is often rotated in proportion to the amount of rotation of the swivel base 14. The driven external gear 45 meshed with the pinion 46 is rotated by the driven rotation of the pinion 46, and the driven external gear 45 rotates along the outer periphery of the shaft support 43 in the rotating direction of the swivel base 14. will rotate in the opposite direction.

小限の範囲で旋回させることができる。Therefore, the work platform 2'0 fixed to the driven external gear 45 and the excavating mechanism 47 also rotate in the opposite direction to the swivel table 14, and the boom 27. Arm 28° Packet 2
The packet 9 is positioned upward from the base end body 26 of the swivel base 14 to the rear of the engine 15, so that the packet 29 does not protrude to the side of the vehicle body 10 and faces toward the rear of the vehicle body 10. In other words, the excavation mechanism 47 undergoes a double rotation by receiving the rotation movement of the swivel table 14 on the vehicle body 10 and the rotation movement of the work table 20 on the swivel table 14 in the opposite direction.
When the excavating mechanism 47 rotates from the front to the rear of the vehicle body 10, it always passes above the swivel base 14 and rotates, and the excavating mechanism 47 rotates within a minimum range so as not to protrude to the side of the vehicle body 10. It can be rotated with.
本発明は上述の様に構成したので、掘削機のパケットを

容易となル、安価に製造することができるものである。Since the present invention is configured as described above, the packet of the excavator can be made eccentric as much as possible and turned from the front to the rear.
Because the packet does not protrude from the side of the vehicle,
The operating range can be narrowed without posing a danger to workers or passersby. Furthermore, since the two rotations of the swivel table and the workbench can be synchronized using a simple external mechanism, the manufacturing and assembly process is easy and the manufacturing process can be carried out at low cost.
