Three pipes, that is, a central sliding pipe 3 and a lower support pipe 11, are fixed.

As shown in FIG. 5, guide plates 12 and 13 are projected from the upper and lower upper support pipes 10 and lower support pipes 11 toward the central sliding pipe 3 so that the guide plates 12 and 13 are sandwiched therebetween. The sliding groove bodies 28, 29 are fitted.

The sliding groove bodies 28, 29 project vertically from the sliding cylinder 4, and the sliding cylinder 4 is loosely fitted on the outer periphery of the central sliding pipe 3.

With this configuration, the sliding cylinder 4 is slid to the left and right outside the central sliding pipe 3, and the sliding groove bodies 28 and 29 projecting vertically from the sliding cylinder 4 extend along the guide plates 12 and 13. Then, the position is fixed to the moving burdock G by the fixing bolts 30 and 31.

The lateral movement of the sliding cylinder 4 loosely fitted around the central sliding pipe 3 can be adjusted by the adjusting bolt 37 interposed between the left and right side plates 1L and 1R. And the excavating blade mounting plates 2L, 2R are projected from the sliding cylinder 4, and the excavating blade mounting plates 2L, 2R are
The excavating blades 7L and 7R inclined forward and downward are fixed to the 2R with bolts.

Left and right side plates 1L and 1R are arranged to fix the left and right ends of the upper support pipe 10, the central sliding pipe 3 and the lower support pipe 11. After the sliding cylinder 4 is fitted into the central sliding pipe 3, the left and right side plates 1L and 1R are applied and fixed to prevent the sliding cylinder 4 from coming off.

In the embodiment shown in FIGS. 6 to 8, the movement of the digging machine by means of the adjusting bolt 37 described above can be forcibly and remotely controlled by the sliding cylinder 5 provided separately.

The sliding cylinder 5 slides only on the left side in the traveling direction of the left and right excavators, and the right side does not move in this embodiment. However, it is also possible to provide two sliding cylinders 5 and move both digging machines.

In the configuration in which the sliding cylinder 5 forcibly slides, only the upper support pipe 10 and the lower support pipe 11 are fixed to the brackets 34L and 34R, and there is no one corresponding to the central slide pipe 3.

However, since the sliding cylinder 25 is loosely fitted on the upper support pipe 10 and the sliding cylinder 26 is loosely fitted on the lower support pipe 11,

(F) Effects of the Invention Since the present invention is configured as described above, it also has the following effects.

First, the distance L between the left and right excavators disposed between the left and right wheels 33L and 33R is set to the upper support pipe 10 and the lower support pipe 11
Since it can be adjusted by making it slidable on the above, even if the interval between the excavated objects is different, the interval of the excavator can be adjusted and matched, so It no longer scratched them by colliding with burdock roots or yams.

Secondly, by moving the excavator to the left and right on the support pipes 10 and 11, even after sliding the excavator, the depth and vibration of the excavator do not change. You can dig under the same conditions as in.

Third, the left and right wheels of the tractor T, as in conventional mining machines.
The mining machine for one line is not arranged between the 33L and 33R, but the two lines on the left and right are configured between the wheels 33L and 33R, improving the work efficiency of the mining work. I was able to improve.

Fourthly, it is impossible to dig two rows at a time with one tractor T due to an increase in required horsepower, but the present invention uses the digging blades 7L and 7R of the left and right double digging machines. By using the vibration type as well, friction and resistance with the soil can be reduced, so that a double-drilling machine is possible.
