Description

Curved cutter groover

Technical field

The utility model relates to a kind of groover, the curved cutter groover that particularly grooving of a kind of underground concrete wall is used.

Background technology

At present, under manufactured place, the groover ubiquity of concrete wall makes that groove speed is slow, complex structure, high cost feature.

Summary of the invention

The utility model has made up above shortcoming, and a kind of curved cutter groover is provided.

The utility model is achieved by the following technical solution:

A kind of curved cutter groover, comprise the connection between several sections of drilling rods and drilling rod, a joint drilling rod lower end is provided with motor bottom, support arm is fixed in electric machine casing lower end, motor shaft lower end is provided with gear, and gear both sides are respectively equipped with a curved cutter and two curved cuttves, and a curved cutter top is provided with several teeth by a side of gear, two curved cutter tops are provided with identical tooth by a side of gear, tooth and gear engagement; The hinged curved cutter left end in one trailing arm lower end, upper end hinged support arm left end; The hinged curved cutter right-hand member in two trailing arm lower ends, upper end hinged support arm right-hand member; The hinged two curved cutter left ends in three trailing arm lower ends, upper end hinged support arm left end; The hinged two curved cutter right-hand members in four trailing arm lower ends, upper end hinged support arm right-hand member; One curved cutter and two curved cutter bottoms are equipped with a plurality of cutter heads.

The utlity model has following beneficial effect:

The utility model uninterruptedly moves back and forth by a curved cutter and two curved cuttves, and the cutter head of a curved cutter and two curved cutter bottoms is soil diging groove-forming at the volley, simple, convenient, feasible.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described;

Fig. 1 is structural representation of the present utility model;

Fig. 2 is A-A view;

Fig. 3 is B-B view;

Fig. 4 is C-C view.

In figure: 1, drilling rod, 2, connect, 3, motor, 4, support arm, 5, one trailing arm, 6, two trailing arms, 7, three trailing arms, 8, four trailing arms, 9, axle, 10, gear, 11, one curved cutter, 12, two curved cuttves, 13, cutter head, 14, tooth.

The specific embodiment

Accompanying drawing is a kind of specific embodiment of the present utility model, this embodiment comprises the connection 2 between several sections of drilling rods 1 and drilling rod, a joint drilling rod lower end is provided with motor 3 bottom, support arm 4 is fixed in electric machine casing lower end, motor shaft 9 lower ends are provided with gear 10, and gear both sides are respectively equipped with a curved cutter 11 and the two curved cutter of curved cutter 12, tops lean on a side of gear to be provided with several teeth 14, two curved cutter tops are provided with identical tooth 14 by a side of gear, tooth and gear engagement; The hinged curved cutter left end in one trailing arm 5 lower ends, upper end hinged support arm left end; The hinged curved cutter right-hand member in two trailing arm 6 lower ends, upper end hinged support arm right-hand member; The hinged two curved cutter left ends in three trailing arm 7 lower ends, upper end hinged support arm left end; The hinged two curved cutter right-hand members in four trailing arm 8 lower ends, upper end hinged support arm right-hand member; One curved cutter and two curved cutter bottoms are equipped with a plurality of cutter heads 13.

Two trisquare shapes that are shaped as symmetry of one curved cutter and two curved cuttves.

During the utility model work, the uninterrupted forward and reverse rotation of motor-driven gear, drives a curved cutter and two curved cuttves uninterruptedly to move back and forth thus, and the cutter head of a curved cutter and two curved cutter bottoms is soil diging groove-forming at the volley.
