Technical field
The utility model belongs to building machinery field, relates to trench machine, is specifically related to a kind of guide wall of underground continuous wall groove groove milling drill bit.
Background technology
Trench machine is machinery important in building machinery, and drill bit is again one of core component of trench machine.Now drill bit on building sites generally can only vertical perforating on the ground, can not the quick groove milling of level.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, provides a kind of guide wall of underground continuous wall groove groove milling drill bit, and this guide wall of underground continuous wall groove groove milling drill bit can carry out the quick groove milling of level.
The utility model comprises bit matrix, teeter column, alloy knife grain, water under high pressure spray column and reinforced pole; Described water under high pressure spray column is fixed on bottom bit matrix; The inner chamber of bit matrix and the inner space of water under high pressure spray column; Described water under high pressure spray column offers multiple high pressure water jets perforation groups of arranging vertically, and each high pressure water jets perforation group comprises the multiple high pressure water jets perforations be uniformly distributed along the circumference; The inner of described high pressure water jets perforation and the inner chamber of water under high pressure spray column through, outer end is open to be arranged; Two teeter column groups are arranged along the axial spacing of water under high pressure spray column, and each teeter column group comprises many teeter columns of the circumference uniform distribution along water under high pressure spray column; Every root teeter column is all by being connected along many reinforced poles of high pressure water jets post axial arranging with water under high pressure spray column; All fix with bit matrix near the teeter column top of bit matrix; Many alloy knife grains are that spatially spiral shape is arranged to top by bottom along the axis of water under high pressure spray column, and are embedded in respectively on corresponding teeter column.
The top of described bit matrix is connected to high pressure water connector.
All alloy knife grains along high pressure water jets axis of a cylinder to projection end to end.
The beneficial effects of the utility model:
The utility model utilizes water under high pressure to break up soil, simultaneously by the alloy knife grain on teeter column to soil cutting, teeter column by the soil cut stir be mixed in water, the effect of the quick groove milling that is up to the standard, lays a good foundation for setting up diaphragm wall; The soil be mixed in water is extracted out by suction pump and is led wall chase; Drill bit is immersed in water, rapid heat dissipation, not fragile.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the top Local map of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As illustrated in fig. 1 and 2, a kind of guide wall of underground continuous wall groove groove milling drill bit, comprises bit matrix 1, high pressure water connector 2, teeter column 3, alloy knife grain 4, water under high pressure spray column 5 and reinforced pole 6; High pressure water connector 2 is fixed on bit matrix 1 top, and water under high pressure spray column 5 is fixed on bottom bit matrix 1; The inner chamber two ends of bit matrix 1 respectively with the inner space of high pressure water connector 2 and water under high pressure spray column 5; Water under high pressure spray column 5 offers 30 high pressure water jets perforation groups of arranging vertically, and each high pressure water jets perforation group comprises 12 the high pressure water jets perforation 5-1 be uniformly distributed along the circumference; The inner of high pressure water jets perforation 5-1 and the inner chamber of water under high pressure spray column 5 through, outer end is open to be arranged; Two teeter column groups are arranged along the axial spacing of water under high pressure spray column 5, and each teeter column group comprises 12 teeter columns 3 of the circumference uniform distribution along water under high pressure spray column 5; Every root teeter column 3 is all connected with water under high pressure spray column 5 by five reinforced poles 6 along water under high pressure spray column 5 axial arranging; All fix with bit matrix 1 near teeter column 3 top of bit matrix 1; 48 alloy knife grains 4 are that spatially spiral shape is arranged to top by bottom along the axis of water under high pressure spray column 5, and are embedded on corresponding teeter column 3 respectively; All alloy knife grains 4 are end to end along the projection of water under high pressure spray column 5 axis, ensure that the soil of circumferentially each position can be switched to.
The operating principle of this guide wall of underground continuous wall groove groove milling drill bit:
High-pressure water pipe is connected with high pressure water connector 2; Bit matrix 1 input power, energizes high-pressure water spray column 5 and teeter column 3 rotate; Water under high pressure in high-pressure water pipe enters in bit matrix 1 and water under high pressure spray column 5 by high pressure water connector 2, then eject from high pressure water jets perforation 5-1, break up the earth of sidewall of not cutting the earth, teeter column 3 is not close to cutting the earth sidewall simultaneously, and soil just can be cut by alloy knife grain 4 further; When providing horizontal onward impulse to bit matrix 1, just dig out diaphragm wall in underground and lead wall chase.
