Abstract

The invention discloses a double-arm groove digger. The lower end of a drill rod is connected with a connecting arm. A cylindrical body is fixed at the lower end of the connecting arm. Two sides of the cylindrical body are provided with a first wheel and a second wheel respectively. The first wheel and the second wheel are fixed at two ends of a middle shaft respectively. The first wheel is meshed with a bevel gear. The bevel gear is driven by a motor through a shaft. A first short shaft is arranged on the first wheel and away from the center of the first wheel by a certain length. A second short shaft is arranged on the second wheel and away from the center of the second wheel by a certain length. The first short shaft is hinged to the right end of a first connecting rod and the second short shaft is hinged to the left end of a second connecting rod. The left end of the first connecting rod is hinged to the upper end of a first arm. A first rod is fixed at the lower end of the first arm. The middle of the first arm is hinged to the left end of a transverse arm and the right end of the second connecting rod is hinged to the upper end of a second arm. A second rod is fixed at the lower end of the second arm. The right end of the transverse arm is hinged to the middle of the second arm. The middle of the transverse arm is fixed on the cylindrical body through a connecting post. The lower portion of the first rod and the lower portion of the second rod are respectively provided with a plurality of alloy cutters.

Description

The both arms groover

Technical field

The present invention relates to a kind of groover, particularly the both arms groover used of a kind of building foundation engineering underground impervious wall grooving.

Background technology

At present, all there is inefficiency in the underground impervious wall groover, equipment complexity, shortcoming such as performance is unreliable.

Summary of the invention

The present invention has remedied above blank, and a kind of both arms groover is provided.

The present invention is achieved through the following technical solutions:

A kind of both arms groover, the drilling rod lower end is connected with linking arm, and fixedly there is cylinder the linking arm lower end, the cylinder both sides are respectively equipped with the first round and second and take turns, the first round and second is taken turns the two ends of being fixed in axis, and the first round is engaged in bevel gear, and bevel gear is driven by axle by motor; The first round, eccentric certain-length was provided with first minor axis, and second takes turns eccentric certain-length is provided with second minor axis, the right-hand member of the hinged first connecting rod of first minor axis, the left end of the hinged second connecting rod of second minor axis; The hinged the first arm of the left end of first connecting rod upper end, first bar is fixed in the first arm lower end, hinged transverse arm left end in the middle of the first arm, hinged second arm of the right-hand member of second connecting rod upper end, second bar is fixed in the second arm lower end, hinged transverse arm right-hand member in the middle of second arm; Be fixed in cylinder by joint pin in the middle of the transverse arm, first bar and the second bar bottom are equipped with a plurality of alloy knifes.

The present invention has following characteristics:

The present invention cuts the earth by the alloy knife move toward one another on the first round and second rotating drive of taking turns, first bar and second bar, and device structure is simple, dependable performance.

Description of drawings

The present invention is further illustrated below in conjunction with accompanying drawing:

Fig. 1 is structural representation of the present invention;

Fig. 2 is A-A view of Fig. 1;

Among the figure: 1, drilling rod, 2, motor, 3, axle, 4, bevel gear, 5, linking arm, 6, first minor axis, 7, first connecting rod, 8, axis, 9, second minor axis, 10, second connecting rod, 11, the first round, 12, joint pin, 13, transverse arm, 14, the first arm, 15, second arm, 16, first bar, 17, second bar, 18, alloy knife, 19, cylinder, 20, second takes turns.

The specific embodiment

Accompanying drawing is a kind of specific embodiment of the present invention, this embodiment drilling rod 1 lower end is connected with linking arm 5, fixedly there is cylinder 19 the linking arm lower end, the cylinder both sides are respectively equipped with the first round 11 and second and take turns 20, the first round and second is taken turns the two ends of being fixed in axis 8, axis can rotate in cylinder, and the first round is engaged in bevel gear 4, and bevel gear is driven by axle 3 by motor; Eccentric certain-length of the first round is provided with first minor axis 6, the second and takes turns the right-hand member that eccentric certain-length is provided with the hinged first connecting rod 7 of second minor axis, 9, the first minor axises, the left end of the hinged second connecting rod 10 of second minor axis; The hinged the first arm of the left end of first connecting rod 14 upper ends, first bar 16 is fixed in the first arm lower end, hinged transverse arm 13 left ends in the middle of the first arm, the middle hinged transverse arm right-hand member of second bar, 17, the second arms is fixed in hinged second arm of the right-hand member of second connecting rod 15 upper ends, the second arm lower end; Be fixed in cylinder by joint pin 12 in the middle of the transverse arm, first bar and the second bar bottom are equipped with a plurality of alloy knifes 18.

The projection on wheel of first minor axis and second minor axis is with respect to the center symmetry of wheel.

When the present invention works, motor is taken turns rotation by the bevel gear driving first round and second, the first round, second takes turns in rotation process and swings in opposite directions by the upper end of first connecting rod, second connecting rod driving the first arm, second arm, alloy knife on first bar and second bar just move toward one another is cut the earth, and native slag mixing mud is by outside the direct circulation drain tank.
