Description

Double drill slotting machine

technical field

The invention relates to a slotting machine, in particular to a double-drill slotting machine for slotting underground walls.

Background technique

At present, the width of the single slot section formed by the slotting machine for constructing the underground wall is generally very small.

Contents of the invention

The present invention makes up for the above shortcomings and provides a double drill slotting machine.

The present invention is achieved through the following technical solutions:

A double-drill slotting machine, including a pulley block for lifting the upper part of the slotting machine, two side rods for guiding on the left and right sides, a submersible motor C on the upper end of the reduction box, and a positive screw and a reverse screw at the left and right ends of the reduction box. There is a positive thread sleeve on the positive screw rod, and the positive thread sleeve is set in the middle of the column A. The upper and lower ends of the column A are respectively equipped with bushings. The bottom end is equipped with a submersible motor A; the anti-screw rod is equipped with an anti-thread sleeve, and the anti-thread sleeve is set in the middle of the column B. The upper and lower ends of the column B are respectively equipped with bushings, and the upper and lower bushes are also respectively sleeved on the horizontal shaft A and The horizontal axis B, the bottom end of the column B is provided with a submersible motor B, and the lower ends of the submersible motor A and submersible motor B are respectively provided with drill bits.

The present invention has the following beneficial effects:

In the present invention, through the reciprocating movement of two drill bits facing each other and in opposite directions, a wider groove section can be drilled at one time.

Description of drawings

Detailed ways

Accompanying drawing is a kind of concrete embodiment of the present invention, and this embodiment comprises pulley group 1 that the upper part of slotting machine is lifted, two side rods 2 that left and right sides are used for guiding, and submersible motor C is arranged on the upper end of reduction box, and left and right sides of reduction box The positive screw rod 8 and the reverse screw rod 9 are respectively provided at the ends, and the positive screw rod 8 is provided with a positive screw sleeve 6, which is fixed in the middle of the column A. The horizontal axis A and the horizontal axis B are respectively socketed, and the submersible motor A is provided at the bottom end of the column A; the anti-thread sleeve 7 is provided on the anti-screw rod 9, and the anti-thread sleeve is fixed in the middle of the column B13, and the upper and lower ends of the column B are respectively equipped with Axle sleeves, the upper and lower two axle sleeves are also respectively sleeved on the horizontal axis A and the horizontal axis B, the bottom end of the column B is provided with a submersible motor B, and the submersible motor A and the lower end of the submersible motor B are respectively provided with a drill bit.

When the screw mandrel rotates, the wire sleeve is driven to move on the screw rod, and when the wire sleeve moves, the column is driven to slide on the horizontal axis through the sleeve.

The upper and lower ends of the reduction box are respectively fixed on the horizontal axis A and the horizontal axis B, and the reduction box is driven by a submersible motor C.

When the present invention works, when the gear box drives the forward screw and the negative screw to rotate forward, the submersible motor A and the submersible motor B move to the left and right sides respectively. When the submersible motor A and the submersible motor B are close to the side rods, the positive screw Reverse the anti-screw to make the submersible motor A and submersible motor B move toward the gear box again, so that the movement is repeated. At the same time, the submersible motor A drives the drill to rotate forward, and the submersible motor B drives the drill to reverse. During the rotation and reciprocating motion of the motor B, the soil is drilled into grooves, and the mud liquid is extracted and replaced by the circulation system.
