[0022] In order to make the above-mentioned purpose, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings of the specification.

[0023] Reference Figures 1 to 4For an embodiment of the utility model, provide a cutting machine dust removal device, this cutting machine dust removal device includes machine body 1, be provided with saw blade 2 on machine body 1, motor 3 is provided with on saw blade 2 side, hand lever 4 is provided with on the protective cover outside saw blade 2, first pulley 7 and second pulley 8 are provided with on machine body 1, the rope 5 is connected on first pulley 7 and second pulley 8, dust removal pipe 10 is provided with above machine body 1, the cover 6 is rotatably provided with below dust removal pipe 10, connecting rod 9 is provided between cover 6 and rope 5.

[0024] Referring to Figure 3 And Figure 4 In the embodiment, first pulley 7 and second pulley 8 are both fixed pulleys, second pulley 8 is arranged below and behind first pulley 7, rope 5 is a steel wire rope, which has higher strength and is not easy to be broken, one end of rope 5 is fixed to hand lever 4, and the other end is fixed to connecting rod 9, rope 5 connected to hand lever 4 is wound over first pulley 7 from above, then is wound under second pulley 8 from front, and is wound out from behind second pulley 8 and is connected to connecting rod 9 above second pulley 8, connecting rod 9 is an "L" shaped rod, two ends of connecting rod 9 are connected to rope 5 and cover 6 respectively, and cover 6 is rotatably arranged on dust removal pipe 10.

[0025] Referring to Figure 2 In the embodiment, fan 11 is arranged in dust removal pipe 10, fan 11 can suck dust generated in the cutting process to the outlet of dust removal pipe 10, preferably, dust removal pipe 10 is designed as an "L" shaped rod, one end of the "L" shaped rod is the inlet of dust removal pipe 10 and is located behind machine body 1 for sucking dust, and the other end of the "L" shaped rod is the outlet of dust removal pipe 10 and is arranged outside a window or in a dust purification treatment device.

[0026] Referring to Figure 1 And Figure 2 In the embodiment, dust collection box 12 is arranged behind machine body 1, and the inlet of dust removal pipe 10 is located above dust collection box 12. In the cutting process, not all dust enters dust removal pipe 10, and part of the dust remains outside dust removal pipe 10, dust collection box 12 is arranged to collect the remaining dust and then treat it, thereby reducing pollution of the working environment and improving the health of the operator; further, seal 13 is arranged on the side of dust collection box 12, in a normal state, seal 13 seals the side of dust collection box 12 to prevent dust leakage, when it is necessary to clean dust in dust collection box 12, seal 13 is pulled open, and dust in dust collection box 12 is cleaned.
