Description

Technical Field

[0001] The utility model belongs to the technical field of cutting machines, and in particular relates to a self-dust-absorption cutting machine. Background Art

[0002] Conventional cutting machines are provided with an air inlet at the rear end of the casing and a fan blade at the front end of the motor's rotor. The fan blade rotates with the motor rotor, and wind enters the motor through the air inlet of the casing for air cooling; the power generated by the rotation of the motor is transmitted from the front end of the motor's rotor through the gear transmission part to the saw blade in the head cover for cutting operations.

[0003] In order to facilitate dust removal during cutting, conventional cutting machines are provided with a dust shield below the head cover along the direction of the sawdust parabola, and a dust outlet is provided above the dust shield. A dust collecting bag is connected to the dust outlet, and the dust outlet can also be connected to a vacuum cleaner.

[0004] In actual use, dust collection is completely dependent on the saw blade cutting rotation force and the wind force generated by the saw blade rotation to throw the dust shield, and then gather in the dust bag through the dust outlet. Without the suction of the additional vacuum cleaner or other external forces, the dust shield and the dust outlet will be filled with chips, especially when cutting wet wood, which will cause dust discharge to be unsmooth.

[0005] In addition, when the cutting position is higher, the direction of the dust outlet is more upward, and dust collection is more difficult under the action of gravity, resulting in poor dust suction, which affects the operating experience, the operating environment and thus the health of the operator.
