Description

Groover cutting knife spins

Technical field

The present invention relates to a kind of cutter, the groover cutting knife that spins that particularly a kind of subterranean wall grooving is used.

Background technology

The groover that spins of building subterranean wall just creeps into a plurality of electric drills rotary impact that is connected in parallel to make groove, because drill bit is circular, so the groove that groover digs is the combination in a plurality of gardens, cell wall very irregular.

Summary of the invention

The present invention has made up above shortcoming, and a kind of groover cutting knife that spins is provided.

The present invention is achieved through the following technical solutions:

A kind of groover cutting knife that spins, motor A upper end jointed rod, lower end connecting cross arm A, the first vertical rod and the second vertical rod are fixed respectively in two ends, transverse arm A left and right, motor A lower end output shaft connecting screw rod, has nut on screw rod, nut the right and left is hinged first connecting rod and second connecting rod respectively, hinged the first pin in first connecting rod upper end, hinged the second pin in second connecting rod upper end; Hinged the 3rd montant upper end of the first cross bar left end, hinged the first pin of the first cross bar right-hand member, hinged the first vertical rod in the middle of the first cross bar, hinged the second pin of the second cross bar left end, hinged the 4th montant upper end of the second cross bar right-hand member, hinged the second vertical rod in the middle of the second cross bar, hinged the 3rd montant lower end of the 3rd cross bar left end, hinged the first montant lower end of the 3rd cross bar right-hand member, hinged the first vertical rod lower end in the middle of the 3rd cross bar, hinged the second montant lower end of the 4th cross bar left end, hinged the 4th montant lower end of the 4th cross bar right-hand member, hinged the second vertical rod in the middle of the 4th cross bar; The first montant, the second montant, the 3rd montant, the 4th montant lower end are fixed with respectively motor B, before and after each motor B is upper, both sides are respectively equipped with cutting knife, cutting knife is parallel with the axis at the place, the center of circle of four motor B, the length of every cutting knife and the equal diameters of drill bit, cutting knife is fixed on motor B shell by linking arm.

The present invention has following beneficial effect:

The present invention is fixed on motor B by cutting knife, and cutting knife is along with the ballistic motion up and down of motor, by bit cutting less than earth cut away.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the present invention is further illustrated;

Accompanying drawing 1 is structural representation of the present invention;

Accompanying drawing 2 is A-A view.

In figure: 1, drilling rod, 2, motor A, 3, screw rod, 4, first connecting rod, 5, second connecting rod, the 6, first montant, the 7, second montant, the 8, first cross bar, 9, the second cross bar, 10, transverse arm A, the 11, first vertical rod, the 12, second vertical rod, 13, the 3rd montant, the 14, the 4th montant, 15, nut, the 16, the 3rd cross bar, 17, the 4th cross bar, 18, cutting knife, 19, motor B, 20, drill bit, 21, the first pin, the 22, second pin, 23, linking arm.

The specific embodiment

Accompanying drawing is a kind of specific embodiment of the present invention, this embodiment motor A2 upper end jointed rod, lower end connecting cross arm A10, the first vertical rod 11 and the second vertical rod 12 are fixed respectively in two ends, transverse arm A left and right, motor A lower end output shaft connecting screw rod 3, has nut 15 on screw rod, nut the right and left is hinged first connecting rod 4 and second connecting rod 5 respectively, hinged the first pin 21 in first connecting rod upper end, hinged the second pin 22 in second connecting rod upper end, hinged the 3rd montant 13 upper ends of the first cross bar 8 left ends, hinged the first pin of the first cross bar right-hand member, hinged the first vertical rod in the middle of the first cross bar, hinged the second pin of the second cross bar 9 left ends, hinged the 4th montant 14 upper ends of the second cross bar right-hand member, hinged the second vertical rod in the middle of the second cross bar, hinged the 3rd montant 13 lower ends of the 3rd cross bar 16 left ends, hinged the first montant 6 lower ends of the 3rd cross bar right-hand member, hinged the first vertical rod lower end in the middle of the 3rd cross bar, hinged the second montant 7 lower ends of the 4th cross bar 17 left ends, hinged the 4th montant 14 lower ends of the 4th cross bar right-hand member, hinged the second vertical rod in the middle of the 4th cross bar, the first montant, the second montant, the 3rd montant, the 4th montant lower end are fixed with respectively motor B19, before and after each motor B is upper, both sides are respectively equipped with cutting knife 18, cutting knife is parallel with the axis at the place, the center of circle of four motor B, the length of every cutting knife and the equal diameters of drill bit, cutting knife is fixed on motor B shell by linking arm 23.
