The technical scheme of the utility model is realized like this: the utility model provides a blade disc structure convenient to disassemble main drive, includes the blade disc flange, the blade disc flange on be equipped with the connecting hole, the blade disc bolt passes the connecting hole and is connected with main drive's front end, connecting hole and sealing member cooperation are equipped with the auxiliary hole on the blade disc flange, the auxiliary hole cooperates with the auxiliary bolt, main drive passes through centre ring bolt and is connected with the rear end of shield body centre ring, the front end of shield body centre ring is equipped with the installation screw hole, installation screw hole cooperates with protection piece, auxiliary bolt.
And a center ring seal matched with the cutter head flange is arranged on the shield body center ring.
The sealing element is provided with a seal.
The protection piece is a protection screw plug.
The shield body center ring is welded in the shield body.
The cutter flange is connected with the cutter.
The realized functions or purposes are as follows:
by adopting the cutter head structure, the sealing performance in the disassembly process of the main drive can be ensured, and the disassembly and maintenance work of the main drive in the hole can be realized more conveniently.
Has the advantages that:
the cutter head structure convenient for disassembling the main drive in the hole can realize safe and stable disassembly of the main drive in the hole, provides convenience for assembly, disassembly and maintenance of the main drive in the hole, improves the construction efficiency, can be realized by optimizing the original design structure, and has the advantages of low investment cost and strong practicability.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.
The cutter head structure convenient for disassembling the main drive comprises a shield body 9, wherein a shield body center ring 3 is arranged on the shield body 9, and a cutter head flange 1 and the main drive 3 are arranged in the shield body 9. The cutter head flange 1 is provided with an auxiliary hole 12 and a connecting hole 13. The front end of the shield body center ring 3 is provided with a mounting threaded hole 14.
Before the main drive is disassembled, the cutter head bolt 6 penetrates through a connecting hole 13 on the cutter head flange 1 to be connected with the front end of the main drive 10, the cutter head flange 1 and the main drive 10 are designed to be totally enclosed, the main drive 10 is connected with the rear end of the shield body center ring 3 through a center ring bolt 11, and a protective screw plug is connected in a mounting threaded hole 14 in the front end of the shield body center ring 3, as shown in fig. 1.
