Abstract
The invention discloses a soil stirring device for the cutter head of a shield tunneling machine. The soil stirring device comprises a cutter head, a connecting flange and a connecting arm, wherein the cutter head and the connecting flange respectively takes the shape of a disk, the cutter head and the connecting flange are welded together by the connecting arm, a driving motor is fixedly installed at the proper position of the cutter head and the connecting arm, a driving shaft is connected to one side of the driving motor, and stirring blades are fixed in the peripheral direction of the driving shaft; according to the soil stirring device, soil is strongly stirred in longitudinal and transverse directions, formation of mud cakes is completely eradicated, and thereby muck discharge speed is further improved, shield tunneling speed is improved and work efficiency is high; the soil stirring device for the cutter head of the shield tunneling machine has the advantages of being easy to produce and mount and low in cost.
Description
Technical field
The present invention relates to a kind of mixing plant, refer to a kind of shield cutter soil shear failure device for shield-tunneling construction especially.
Background technology
When balancing earth-pressure shielding machine carries out set of tunneling construction, if through cutting the soil body entering native cabin, not stirred fully, then easily forming mud cake, affect dregs and discharge, time serious, will quality and the progress of engineering construction be affected.
Summary of the invention
The problem to be solved in the present invention is the deficiency overcome in background technology, provides a kind of shield cutter soil shear failure device, this shield cutter soil shear failure device, adopts driven by power, can realize the abundant stirring to the soil body, promotes the dregs velocity of discharge further.
For solving the problem, the present invention takes following technical scheme:
A kind of shield cutter soil shear failure device of the present invention, comprise cutterhead, adpting flange, linking arm, described cutterhead and adpting flange in the form of annular discs, described cutterhead and adpting flange are welded together by linking arm, the side of the SCCP connection-oriented flange of described cutterhead, the first drive motors is installed with near the appropriate location of excircle, described first drive motors side is connected with the first driving shaft, the circumferencial direction of described first driving shaft is fixed with the first agitator, the outer fix of described linking arm is installed with the second drive motors, the side of described second drive motors is connected with the second driving shaft, the circumferencial direction of described second driving shaft is fixed with the second agitator.
A corrective measure of the present invention is: described first drive motors closes the inside being arranged on cutterhead, and described second drive motors closes the inside being arranged on linking arm.
Further improvement of the present invention measure is: described first drive motors, the first driving shaft, the first agitator are arranged on cutterhead in groups, and described second drive motors, the second driving shaft, the second agitator are installed on the connecting arm in groups.
Further corrective measure of the present invention is: described first drive motors, the first driving shaft, the first agitator are arranged on cutterhead by the Central Symmetry of cutterhead in groups.
A kind of shield cutter soil shear failure device of the present invention, due to the side of the SCCP connection-oriented flange at cutterhead, the first drive motors is installed with near the appropriate location of excircle, described first drive motors side is connected with the first driving shaft, the circumferencial direction of described first driving shaft is fixed with the first agitator, the outer fix of described linking arm is installed with the second drive motors, the side of described second drive motors is connected with the second driving shaft, and the circumferencial direction of described second driving shaft is fixed with the second agitator.Therefore, when needs fully stir the soil body, can start the drive motors that drive motors and linking arm that cutterhead is installed are installed, drive motors drives agitator to rotate by driving shaft, realize the strong stirring soil body in both direction in length and breadth, thoroughly stop the formation of mud cake.The present invention improves the dregs velocity of discharge further, and improve shield driving speed, not only operating efficiency is high, but also has easy manufacture, easily installation, low cost and other advantages.
