Provided is a double-screw grooving machine. A drill stem is connected with the upper end of a motor. A gearbox is connected with the lower end of the motor. A left screw rod is arranged at the left side of the gear box. Two screw outer sleeves are arranged on the left screw rod. A right screw rod is arranged at the right side of the gear box. Two screw outer sleeves are also arranged on the right screw rod. Each of shifting forks is fixed at the lower end of each of the four screw outer sleeves. Four vertical rods are respectively arranged on the lower portion of each of the four shifting forks. Each of block shafts is fixed at the upper end of each vertical rod. The lower end of each vertical rod is fixed on each of knife rests. The middle portion of each vertical rod is hinged with a supporting rod through each of pins. According to the double-screw grooving machine, by means of the left screw rod and the right screw rod, the four knife rests are driven to swing in a reciprocating mode and in opposite directions to cut geology soil for grooving. The double-screw grooving machine is simple and reliable in structure.
Description
technical field [0001] The invention relates to a grooving machine, in particular to a double-helix grooving machine for underground continuous wall grooving. Background technique [0002] At present, the groove forming machines for constructing underground diaphragm walls generally have the characteristics of complex structure and high cost. Contents of the invention [0003] The present invention makes up for the above shortcomings and provides a double-helix groove forming machine. [0004] The present invention is achieved through the following technical solutions: [0005] A double-helix grooving machine, the upper end of the motor is connected with a drill pipe, the lower end of the motor is connected with a gearbox, a left-handed screw is provided on the left side of the gearbox, two helical jackets are arranged on the left-handed screw, and a right-handed screw is installed on the right side of the gearbox. There are also two helical casings on the screw rod, and...
