The four fixing bolts 104 are threadedly connected to the rear cover 102 and penetrate the front cover 103. The four guide blocks 105 are fixedly connected to the front cover 103 and are located on the outside of the front cover 103. The mounting piece is detachably connected to the front cover 103 and is located on the outside of the front cover 103. The buffer is fixedly connected to the mounting piece and is located on the outside of the mounting piece. The protection plate 106 is fixedly connected to the four groups of buffers and is located on the outside of the buffer. The punch plate 107 is detachably connected to the protective plate 106 and is located on the outside of the protective plate 106. The two groups of disassembly parts are symmetrically arranged. The disassembly parts are detachably connected to the buffer plate 107 and are located on the outside of the protective plate 106. The rear cover 102 is sleeved on the wall surface of the wind tube body 101, and the front cover 103 is installed on the front end of the wind tube body 101 through the fixing bolts 104.

The mounting cover 108 is connected to the front cover 103 through the locking bolt 110. The hand screw 115 is rotated, and the abutment plate 116 fixes the buffer plate 107. The buffer plate 107 withstands the impact of flying stones. When the impact is sustained, the protective plate 106 compresses the telescopic rod 112. The telescopic rod 112 slides in the fixed tube 111, and the spring 113 is compressed. The self-resetting force of the spring 113 offsets the impact force of the flying stones and pushes the protective plate 106 to reset. When the buffer plate 107 is sunken due to excessive impacts, the hand screw 115 is rotated, and the abutment plate 116 cancels the fixation of the buffer plate 107. The buffer plate 107 can be directly disassembled and quickly installed, thereby providing all-round protection for the air duct, effectively preventing the air duct from being impacted by smaller flying stones, and providing the disassembly part facilitates the quick installation and replacement of the buffer plate 107.
