Detailed ways

The present application will be further described in detail below in conjunction with Figures 1-3.

The embodiment of the present application discloses a dust-proof tamping machine.

Referring to Figure 1, a dust-proof tamping machine includes a body 1. A dust box 2 and a dust hood 3 are provided on one side of the body 1. A connecting pipe 4 is connected between the dust hood 3 and the dust box 2. , an exhaust fan 41 for extracting air into the dust collecting box 2 is installed on the wall of the connecting pipe 4, and an exhaust port 5 is provided through the top of the dust collecting box 2. When the worker uses the tamping machine to ram the pile, the exhaust fan 41 is started, and the exhaust fan 41 draws the dust into the dust collecting box 2 through the dust collecting hood 3 and the connecting pipe 4 for collection, thereby reducing the time required for tamping work. The dust produced.

Referring to Figures 1 and 2, rollers 8 are installed at the four corners of the bottom of the dust box 2. A connecting shaft 81 is fixedly connected between any two opposite rollers 8.
