[0006] Preferably, the rotating structure includes a hexagonal turntable, a connecting rod, a first bevel gear, a second bevel gear, a threaded rod, a threaded ring and a scraper. The hexagonal turntable is fixedly connected to the connecting rod. Two groups of first bevel gears are installed on the outer wall of the connecting rod. Each group of the first bevel gears is engaged with a group of second bevel gears. The upper ends of the two groups of the second bevel gears are fixedly connected to a group of threaded rods. The outer wall of each group of the threaded rods is threadedly connected to a group of threaded rings, and a scraper is connected between the two groups of threaded rings.

[0007] Preferably, the connecting rod is rotatably connected to the inner wall of the dustproof frame, the connecting rod is meshedly connected to the second bevel gear through the first bevel gear, and the scraper is threadedly connected to the threaded rod through a threaded ring.

[0008] Preferably, the mounting structure includes a first mounting plate, a connecting ring, a spring and a second mounting plate, the second mounting plate is installed inside the shell structure, a spring is installed between the second mounting plate and the connecting ring support, two groups of first mounting plates are provided, and several groups of connecting rings are provided at the rear ends of the two groups of first mounting plates.

[0009] Preferably, the inner wall of the shell structure is provided with a mounting groove, and the shell structure is fixedly connected to the second mounting plate through the provided mounting groove. The rear end of the first mounting plate is provided with a fixing groove, and the first mounting plate is fixedly connected to the connecting ring through the provided fixing groove.

[0010] Preferably, the shell structure and the dustproof frame are rotatably connected using a connecting block and a connecting head, and the connecting block and the connecting head are connected using connecting bolts.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:
