A plurality of groups of connection components 3 are equidistantly distributed at the connection between the installation shell 1 and the cutter head 2. A plurality of groups of installation mechanisms 4 are equidistantly distributed on the surface of the cutter head 2.

[0027] The inside of the installation shell 1 is movably installed with the cutter head 2.

[0028] Through the installation mechanism 4, the protective shell 44 and the groove 41 can be installed, so as to facilitate the removal of the protective shell 44 and the hob 413 from the cutter head 2, facilitate cleaning or replacement, and can also be quickly installed and limited and fixed by the second screw 47. Thus, it is convenient to replace the hob 413, which takes less time, has little impact on the working hours, does not delay the work process, and is easy to operate.

[0029] As Figure 2 shown, the connection component 3 includes a docking groove 31. A plurality of groups of docking grooves 31 are equidistantly distributed on the front end face of the installation shell 1. A first screw hole 32 is opened at the bottom of the docking groove 31. A plurality of groups of fixedly installed docking blocks 33 are equidistantly distributed on the outer end face of the cutter head 2. A first through hole 34 is opened on the surface of the docking block 33. A first screw 35 is movably inserted into the inner wall of the first through hole 34.

[0030] The docking groove 31 matches the docking block 33 and is movably installed.

[0031] The first screw 35 is threadedly connected to the first screw hole 32.

[0032] As Figures 3-5 shown, the installation mechanism 4 includes a groove 41. Multiple groups of grooves 41 are equidistantly distributed on the surface of the cutter head 2. Guide grooves 42 are symmetrically formed on the left and right inner walls of the groove 41. Screw holes 43 are symmetrically formed on both sides of the upper surface of the groove 41. A protective shell 44 is movably installed inside the groove 41. Guide blocks 45 are symmetrically and fixedly installed on both sides of the protective shell 44. Multiple groups of through holes 46 are equidistantly distributed on both sides of the upper surface of the protective shell 44. A screw rod 47 is movably inserted into the through hole 46. An installation seat 48 is fixedly installed on the lower left side inside the protective shell 44. A micro motor 49 is fixedly installed on the upper end of the installation seat 48. The output rod of the micro motor 49 is drivingly connected to a transmission gear 410. A rotating shaft 411 is rotatably connected to the middle inside the protective shell 44. A driven gear 412 is fixedly sleeved on the outer left end of the rotating shaft 411. Multiple groups of hob cutters 413 are fixedly sleeved on the outer part of the rotating shaft 411.

[0033] The guide block 45 is matched with the guide groove 42 and is movably connected. The screw rod 47 is threadedly connected to the screw hole 43.

[0034] The transmission gear 410 meshes with the driven gear 412.

[0035] By arranging the guide block 45 and the guide groove 42, it is convenient for the protective shell 44 to be stably and quickly inserted into the groove 41, facilitating rapid installation.

[0036] Next, the working principle of the device for replacing the hob cutter of the high-efficiency pipe jacking machine will be specifically described.

[0037] As Figures 1-5As shown, when the device for replacing the hob of the high-efficiency pipe jacking machine is in use, when the cutter head 2 needs to be installed on the mounting shell 1, the docking block 33 outside the cutter head 2 can be aligned with the docking groove 31 on the mounting shell 1, and the docking block 33 can be installed into the docking groove 31, so that the cutter head 2 is installed into the mounting shell 1. Then, when the first screw 35 is inserted through the first through hole 34 into the first screw hole 32 and tightened, the cutter head 2 can be limited and fixed, so that the cutter head 2 is fixedly installed on the mounting shell 1, thus facilitating the use of the pipe jacking machine. At the same time, the micro motor 49 can be started. The micro motor 49 drives the transmission gear 410 to rotate. The rotating transmission gear 410 can drive the rotating shaft 411 to rotate synchronously through the meshing driven gear 412, so that multiple groups of hobs 413 can be driven to rotate simultaneously, thus facilitating the work of the pipe jacking machine and improving the use effect of the pipe jacking machine. When the protective shell 44 needs to be disassembled, the first screw 35 can be loosened and pulled out from the first screw hole 32, so that the cutter head 2 can be separated from the mounting shell 1. Then, the second screw 47 is loosened and pulled out from the second screw hole 43, so that the protective shell 44 can be taken out from the groove 41 on the cutter head 2, thus facilitating its replacement or cleaning. After the protective shell 44 and the hob 413 are cleaned, the protective shell 44 can be reinserted into the groove 41, so that the guiding block 45 will also be inserted into the guiding groove 42, thus facilitating the quick installation of the protective shell 44. Then, the second screw 47 is inserted through the second through hole 46 into the second screw hole 43 and tightened, so as to limit and fix the protective shell 44, so that the protection can be fixedly installed on the cutter head 2. Then, the cutter head 2 is installed on the mounting shell 1, thus facilitating the work of the pipe jacking machine, facilitating the replacement and installation of the hob 413, improving the efficiency, and improving the practicability of the pipe jacking machine.
