The purpose of the utility model can be realized by the following technical scheme:
the utility model provides a reduce blade disc outer loop structure of rock pipe push bench sediment, includes the quotation, the quotation outer peripheral face has cup jointed the inner ring muscle, radian such as inner ring muscle outer peripheral face distributes and has a plurality of swift current cinder boards, and is adjacent all be provided with the swift current sediment outer loop between the swift current cinder board, the swift current sediment outer loop welds in inner ring muscle outer peripheral face, be provided with the swift current sediment passageway between swift current cinder board, blade disc inner ring muscle, the swift current sediment outer loop.
Furthermore, the cross section of each slag slide is isosceles trapezoid, and the number of the slag slide is eight.
Furthermore, a plurality of twisting legs are arranged at the bottom of the plate surface in an equal radian mode, and a plurality of slag inlet holes are formed in the upper surface of the plate surface in an equal radian mode.
Furthermore, two hobbing cutters are arranged between every two adjacent slag inlet holes and are obliquely arranged on the upper surface of the disc surface.
Furthermore, the slag slide plate, the cutter head inner ring rib and the slag slide outer ring are alternately distributed on the side surface of the disc surface.
Further, the slag slide plate is made of stainless steel, and the thickness of the slag slide plate is 1-2 mm.
The utility model has the advantages that:
the utility model discloses a reduce blade disc outer loop structure of rock pipe pushing jack sediment, through the quotation in rotatory process bottom equal radian setting turn round the leg to the broken slag of quotation one side rock, simultaneously the hobbing cutter of quotation upper surface breaks into the broken slag to the rock of quotation opposite side, through setting up and turning round leg and hobbing cutter, carry out high-efficient breakage to the rock of quotation both sides, prevent effectively that the single face of quotation from breaking and can't fully smash the rock, improve greatly the crushing efficiency of quotation to the rock, in the crushing process with the broken slag along the inner ring muscle and the swift current sediment passageway that sets up between the swift current sediment outer loop and the swift current slag board gets into quotation slag inlet hole, through this setting, make the broken slag more easy along getting into quotation slag inlet hole, thereby can reduce the sediment that the rock pipe pushing jack produced in construction, and then reduce the sediment and get into the pipeline outer wall, prevent that the broken slag, causing the pipe to lock.
