Grooving machine with three saw rods

Abstract

A grooving machine with three saw rods capable of advancing in clay comprises a supporting shaft and a hoisting lug. The supporting shaft is arranged on the upper portion of the grooving machine, the hoisting lug is disposed on the lower portion of the grooving machine, a sandstone pump is fixed at the lower end of a slurry outlet steel tube, a suction opening is arranged at the bottom end of the sandstone pump, and the upper end of the slurry outlet steel tube is connected with a slurry outlet rubber tube; upper ends of a rocker arm A, a rocker arm B, a rocker arm C and a rocker arm D are connected to the slurry outlet steel tube, the lower end of the rocker arm A is connected to a connector A, the lower end of the rocker arm B is connected to a base, the lower end of the rocker arm C is connected to a base B, the lower end of the rocker arm D is connected to a connector C, the connector A, a connector B and the connector C are respectively used for being connected with upper portions, middles and lower portions of a cutter arbor A and a cutter arbor C, and the base A and the base B are respectively disposed at the upper end and the lower end of a cutter arbor B; the left lower end of a connecting rod A is connected to the right upper end of the cutter arbor C via a pin, the right upper end of the connecting rod A is hinged to a crankshaft, the left lower end of a connecting rod B is connected to the right upper end of the cutter arbor B via a pin, the right upper end of the connecting rod B is hinged to the crankshaft, and the left upper end of the crankshaft is connected to a driving power speed reducer; and a plurality of cutter plates are disposed at the bottom of each of the cutter arbor A, the cutter arbor B and the cutter arbor C. The grooving machine is a special machine tool for building underground continuous walls.

Description

1. Technical field [0001] The invention relates to a slotting machine, in particular to a three-saw bar slotting machine for slotting underground continuous walls 2. Background technology: [0002] At present, the saw bar slotting machines used in the construction of underground diaphragm walls are all single saw bar slotting machines. When slotting in clay, the sticky mud adheres between the blades and moves with the blades. Therefore, It is difficult or impossible for general slotting machines to slot in clay. 3. Contents of the invention: [0003] The invention makes up for the shortcomings of the single-saw-bar slotting equipment, and provides a three-saw-bar slotting machine capable of slotting in clay. [0004] The present invention is achieved through the following technical solutions: [0005] A three-saw bar slotting machine, including a support shaft at the upper part of the slotting machine, lifting lugs at the lower part, a sand pump fixed at the lower end of...
