When the lifting cylinder device 9 is extended, the groove digging blade 6 is lowered, and the backfilling blade 8 is also lowered together with this.

When the lifting cylinder device 9 is extended even after the backfilling blade 8 has touched the ground, only the trenching blade 6 is dug into the soil and a trench is dug by the blade 6 as the tractor 3) travels. .

At the same time, underground objects, such as gravel, supplied onto the pedestal 17 are transferred to the first and second conveyors 14, 15 and the chute 18.
After that, it is thrown into the groove.

Thereafter, the soil on both sides of the trench is dug by the trench digging blade 6 and then backfilled into the trench by the backfilling blade 8 which is in contact with the ground, thereby burying the underground object.

The depth of the groove is determined by the expansion and contraction movement of the elevating cylinder device 9, and at this time the groove digging blade 6 is moved in parallel.

Further, the height of the first transporter 7 14 is adjusted using a height adjusting screw 16, and the attitude of the backfilling blade 8 is adjusted by changing the length of the connecting member 12.

Moreover, the underground objects may be supplied into the trench not by the conveyors 14 and 15, but from another machine moving in parallel, or by hand.

In this case, the conveyor 14, 15 and the chute 18 are no longer necessary.

The present invention has been constructed as described above, and is attached to a towing frame 1 to be towed by a tractor 3 through a parallel four-bar link whose one end 2 is pivoted to the towing frame 1 and is rotatable in the vertical direction.
