[0016] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0017] Embodiment 1:

[0018] like Figure 1-3 As shown, a protective device for preventing dust and iron pins of a boring head includes a boring head body 1 and a cutter head 2. The left and right sides of the cutter head 2 are respectively connected to a first protective baffle 3 and a second protective baffle 4. The first protective baffle 3 and the second protective baffle 4 are both slidably connected to the boring head body 1 so that they can slide back and forth with the cutter head 2.

[0019] Specifically, at least one of the first protective baffle 3 and the second protective baffle 4 is a telescopic protective baffle, and the telescopic protective baffle is an accordion-type protective baffle, and its surface is reinforced by a steel plate.

[0020] In this embodiment, since the cutter head 2 only moves to the right side of the center, the first protective baffle 3 is a protective steel plate, and the second protective baffle 4 is a telescopic protective baffle, that is, the right side is a telescopic protective baffle, and the inner end of the first protective baffle 3 is fixed to the cutter head 2 by bolts or screws, and the inner end of the telescopic protective baffle is fixed to the cutter head 2 by bolts or screws, and the outer end is fixed to the boring head body 1.

[0021] In some embodiments, a first side guard plate 5 and a second side guard plate 6 are respectively provided on the left and right sides of the boring head body 1. The first side guard plate 5 and the second side guard plate 6 can be fixed on the left and right sides of the boring head body 1 by bolts or screws, wherein the first side guard plate 5 and the protective steel plate are on the same side, and the first side guard plate 5 is provided with a folded edge 51 extending to one side of the protective steel plate, and the folded edge 51 overlaps with the outer end of the protective steel plate. When the cutter head 2 moves from the center to the right, the protective steel plate will move to the right with it. Since the folded edge 51 overlaps with the protective steel plate, the folded edge 51 will block the gap caused by the movement of the protective steel plate to the right, thereby ensuring the protection and shielding performance.

[0022] Specifically, pressure plates 7 are respectively provided on the upper and lower sides of the cutter head 2, and the pressure plates 7 can be fixed to the boring head body 1 by bolts or screws. Guide grooves 71 are respectively provided on the pressure plates 7 on the upper and lower sides, and the upper and lower sides of the first protective baffle 3 and the second protective baffle 4 are respectively slid and guided along the guide grooves 71.

[0023] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
