Especially; Said center cutter drive device carries out transmission by bearing and drive sleeve; Said drive sleeve is connected with the transition panel through bolt; The rotary inner ring of said transition panel and secondary base bearing is through Bolt Connection, and the rotary inner ring of said secondary base bearing is provided with internal gear and matches with the external gear of the output of secondary drive system, and the rotation outer ring of said secondary base bearing and secondary drive system are passed through Bolt Connection on the main casing of secondary base bearing; The main casing of said secondary base bearing links to each other through the load-carrying ring of bolt and cutterhead, and the rotation inner ring that is provided with internal tooth of base bearing matches with the gear of output end of main drive system; The static outer ring of base bearing links to each other through bolt with the base bearing main casing, and said main drive system is fixed on the base bearing main casing.
Especially, on the said central cutting cutterhead single-blade hobboing cutter and twolip hobboing cutter are installed.
Especially, said central cutting cutterhead is installed in the cutterhead of the annulus a that is welded with two symmetries and annulus b in the heart, and the central cutting cutterhead can rotate within it.
Especially, be provided with the MULTIPLE DYNAMIC sealing between transition panel and the main casing, and can relatively rotate.
Especially, rotary joint is fixed on the base bearing main casing, and said rotary joint is connected with the output hydraulic circuit with the input hydraulic pressure oil circuit, and the output hydraulic circuit is connected with the secondary drive system of hydraulic motor.
The beneficial effect of the utility model is: owing on the central cutting cutterhead center cutter drive device is installed; So can realize central cutting cutterhead quick rotation; In order to cracking lithosphere, the operator dish slowly runs cracking the weak soil layer, thereby realizes that operator dish and central cutting cutterhead are when cracking some special stratum; The progress that guarantees the two is consistent, to realize the smooth driving of shield machine.
