The invention relates to the related technical field of shield tunneling machines, in particular to a shield tunneling machine hob with good sealing performance, and solves the problems that in the prior art, a common shield tunneling machine hob head is poor in sealing performance, so that the splashing condition of dug soil is easy to occur, the soil is inconvenient to collect, and the abraded hob cannot be conveniently changed. The shield tunneling machine hob with good sealing performance comprises an outer frame, a center plate and a threaded rod, wherein sealing plates are arranged at the upper side and the lower side of the inside of the outer frame; soil outlets are formed in the inner sides of the sealing plates; fixing plates are arranged at the left side of each sealing plate; afirst rotating shaft is fixed to the inner side of each fixing plate; the center plate is arranged at the left side of the outer frame; first open grooves are formed in the middle of the center plate; a supporting plate is arranged at the outer side of the center plate; the outer side of the supporting plate is connected with the inner wall of the outer frame; meanwhile, second open grooves are formed in the supporting plate; and a movable frame is arranged inside each of the first open grooves and the second open grooves.
Description
technical field [0001] The invention relates to the technical field related to the shield machine, in particular to a shield machine hob with good sealing performance. Background technique [0002] The shield machine is a tunnel boring machine that uses the shield method. The shield construction method is to construct the "shield" of the tunnel while the tunnel boring machine is driving. It is different from the open construction method. When excavating the tunnel, it needs Use hob. [0003] Common shield machine hobs are poorly sealed, resulting in the excavated soil being prone to splashing, making it inconvenient to collect the soil and inconvenient to replace worn hobs. Contents of the invention [0004] The purpose of the present invention is to solve the problem of poor sealing of the hob frame of the shield machine in the prior art, which causes the excavated soil to splash easily, making it inconvenient to collect the soil and inconvenient to wear and tear In vie...
