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 the bottom view of connecting lever, gear and connection;

Fig. 3 is A-A view;

Fig. 4 is B-B view;

In figure: 1, drilling rod, 2, motor, 3, axle sleeve, 4, axostylus axostyle A, 5, linking arm, 6, rotating shaft A, 7, gear A, 8, armed lever A, 9, armed lever B, 10, pin A, 11, pin B, 12, bar A, 13, bar B, 14, pin C, 15, connecting lever A, 16, connecting lever B, 17, cutter head, 18, bar C, 19, bar D, 20, gear C, 21, axle C, 22, rotating shaft B, 23, gear B, 24, pin D, 25, axostylus axostyle B.

The specific embodiment

Accompanying drawing is a kind of specific embodiment of the present utility model, this embodiment drilling rod 1 lower end is provided with motor 2, linking arm 5 is fixed in motor lower end, motor shaft C21 lower end is fixed with gear C 20, both sides difference meshing gear A7 and gear B 23 before and after gear C, in the middle of gear A, be provided with rotating shaft A6, rotating shaft A is fixed on linking arm front end in upper end, in the middle of gear B 23, be provided with rotating shaft B22, rotating shaft B is fixed on linking arm rear end in upper end, in gear A, with a certain distance from rotating shaft A, be provided with pin C14, in gear B, with a certain distance from rotating shaft B, be provided with pin D24, pin C is by armed lever B9 swivel pin B11, pin D is by armed lever A8 swivel pin A10, the left end of connecting lever A15 is fixed in pin A lower end, the right-hand member of connecting lever B16 is fixed in pin B lower end, connecting lever A, connecting lever B bottom is respectively equipped with a plurality of cutter heads.

Linking arm rear and front end is fixed axostyle A4 and axostylus axostyle B25 respectively, and bar A12 upper end is socketed on axostylus axostyle A left end by axle sleeve, and bar A is fixed on lower end connecting lever B left end; Bar B13 upper end is socketed on axostylus axostyle A right-hand member by axle sleeve, and bar B is fixed on lower end connecting lever B right-hand member; Bar C18 upper end is socketed on axostylus axostyle B left end by axle sleeve, and bar C is fixed on lower end connecting lever A left end; Bar D19 upper end is socketed on axostylus axostyle B right-hand member by axle sleeve, and bar D is fixed on lower end connecting lever A right-hand member.

During the work of this rig, motor-driven gear C rotation, gear C driven gear A, gear B rotation, during gear A rotation, pass through armed lever B push-and-pull connecting lever B, during gear B rotation, by armed lever A push-and-pull connecting lever A, so, connecting lever A and connecting lever B just do relatively reciprocating motion, cutter head is cut native pore-forming at the volley, and pore-forming mud is by anti-cyclic permutation.
