Abstract

The utility model discloses a double-helical trenching machine. The upper end of a motor is connected with a drill pipe, the lower end of the motor is connected with a transmission gear, a left-handed screw is arranged at the left side of the transmission gear, two outer helical sleeves are arranged on the left-handed screw, a right-handed screw is arranged at the right side of the transmission gear, two outer helical sleeves are also arranged on the right-handed screw, and shift forks are respectively fixed at the lower ends of the four outer helical sleeves; and four vertical rods are respectively arranged on the lower parts of the four shift forks, a retaining shaft is fixed at the upper end of each vertical rod, the lower end of each vertical rod is fixed on a tool rest, the middle of each vertical rod is hinged with a support rod through a pin, and each retaining shaft is arranged between the two shift arms of each shift fork. The left and right screws drive four tool rests to swing in an opposite reciprocating manner, so that geological soil is cut to form trench, and the double-helical trenching machine is simple and reliable in structure.

Description

The double helix groover
Technical field
The present invention relates to a kind of groover, particularly the double helix groover used of a kind of continuous wall trench underground.
Background technology
At present, build groover ubiquity complex structure, the high cost characteristics of diaphragm wall.
Summary of the invention
The present invention has made up above shortcoming, and a kind of double helix groover is provided.
The present invention is achieved through the following technical solutions:
A kind of double helix groover, the motor upper end is connected with drilling rod, the motor lower end is connected with gearbox, the gearbox left side is provided with left-handed screw, left-handed screw is provided with two spiral sleeves, gearbox the right is provided with right handed screw, also is provided with two spiral sleeves on right handed screw, and four spiral sleeve lower ends are fixed with shift fork respectively; Four shift fork bottoms are respectively equipped with four vertical rods, and each vertical rod upper end is fixed with gear shaft, and knife rest is fixed in the lower end, middle by pin hinged support bar, gear shaft is located between two wiper arms of shift fork, and support bar is fixed in the gearbox lower end by connector, is equipped with several cutter heads under each knife rest.
The present invention has following beneficial effect:
The present invention is by the reciprocally swinging cutting geology soil grooving in opposite directions of four knife rests of two of left and right screw drive, and is simple in structure, reliable.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing;
Fig. 1 is structural representation of the present invention;
In figure: 1, drilling rod, 2, motor, 3, gearbox, 4, left-handed screw, 5, right handed screw, 6, spiral sleeve, 7, shift fork, 8, gear shaft, 9, vertical rod, 10, pin, 11, knife rest, 12, cutter head, 13, connector, 14, support bar.
The specific embodiment
Accompanying drawing is a kind of specific embodiment of the present invention, this embodiment motor upper end is connected with drilling rod, the motor lower end is connected with gearbox 3, the gearbox left side is provided with left-handed screw 4, left-handed screw is provided with two spiral sleeves 6, gearbox the right is provided with right handed screw 5, also is provided with 6, four of two spiral sleeves spiral sleeve lower end on right handed screw and is fixed with respectively shift fork 7; Four shift fork bottoms are respectively equipped with four vertical rods 9, each vertical rod upper end is fixed with gear shaft 8, knife rest 11 is fixed in the lower end, middle by pin 10 hinged support bars 14, gear shaft 8 is located between two wiper arms of shift fork, support bar is fixed in the gearbox lower end by connector, is equipped with several cutter heads 12 under each knife rest.
When the present invention works, motor drives left-handed screw, the synchronous clockwise direction rotation of right handed screw by gearbox, make two spiral sleeves on two spiral sleeves on gearbox the right and the left side synchronously after gearbox motion certain distance, left and right two screw rods another mistake clockwise rotation, make spiral sleeve motion in the other direction again, so repeatedly, shift fork on spiral sleeve is stirred the gear shaft left and right reciprocating motion of vertical rod upper end, drive four knife rests reciprocally swinging in opposite directions, cutter head cutting geology soil grooving on knife rest, grooving mud is replaced by the circulating system.
