The purpose of this embodiment is to provide a novel timber slitting saw, when solving and carrying out wood cutting, the saw-dust and the powder of production fly in disorder, harm health, and the problem of the collection of being not convenient for.

Hereinafter, embodiments will be described with reference to the drawings. The embodiments described below do not limit the scope of the invention described in the claims. Further, the entire contents of the configurations shown in the following embodiments are not limited to those necessary as a solution of the invention described in the claims.

Referring to fig. 1, in the present embodiment, the novel wood cutting saw includes a table, a cutting device, a dust collecting device, and a sealing case 6. The workbench comprises a support frame 1 and a workbench plate 2 which is arranged on the support frame 1 and used for placing wood, wherein the support frame 1 consists of support columns which are arranged below the workbench plate 2 as shown in figure 1; the cutting device comprises a saw blade 3 and a power device for driving the saw blade 3 to rotate, the power device is a motor, the motor is fixedly arranged below the working table plate 2 in a bolt connection mode, the saw blade 3 is sleeved on an output shaft of the motor, or the saw blade 3 and the motor are connected through a transmission mechanism so that the motor drives the saw blade 3 to rotate, and the upper end of the saw blade 3 extends out of the upper end face of the working table plate 2 to cut wood; the dust collecting device comprises a dust collecting box 4 and a fan 5 arranged in the dust collecting box 4, a dust inlet 41 and a dust outlet 42 are arranged on the dust collecting box 4, and the dust collecting device is arranged on one side of the saw blade 3 and is positioned below the workbench plate 2. The fan 5 is arranged in the inner cavity of the dust collecting box 4. The dust inlet 41 is an opening hole arranged on the side wall of the dust collecting box 4, and a net structure is arranged on the opening hole. Preferably, the air inlet of the fan 5 is correspondingly arranged at the dust inlet 41, and the air outlet of the fan 5 is correspondingly arranged at the dust outlet 42, so that the sawdust entering the dust collecting box 4 can be discharged in time more effectively, and the sawdust is prevented from being accumulated in the dust collecting box 4; the sealed shell 6 sets up in the one side of saw bit 3, and sealed shell 6 is connected with dust collection box 4 and forms the space that can hold saw bit 3 and saw-dust, and sealed shell 6 uses transparent material, can be transparent plastics material.

Fan 5 is located dust collection box 4, dust collection box 4 forms a space that can hold saw bit 3 and saw-dust with sealed shell 6, starter motor, saw bit 3 rotates, the produced saw-dust of cutting timber gets into in the space that dust collection box 4 and sealed shell 6 enclose, start fan 5, fan 5 rotates and produces the negative pressure in making dust collection box 4 with the air flow rate in the dust collection box 4 with higher speed, attract the saw-dust to get into dust collection box 4, discharge through dust outlet 42 at last, and because fan 5 operates, in time with the saw-dust attraction to dust collection box 4 in, avoided the saw-dust to pile up and influence the drawback of saw bit 3 normal pivoted in the space that dust collection box 4 and sealed shell 6 enclose. So set up, when solving and carrying out wood cutting, the saw-dust and the powder of production fly in a confused state of mind, harm health, and the problem of the collection of being not convenient for.

As a preferable scheme of the present embodiment, the novel wood cutting saw further includes a dust cover 7 disposed above the worktable 2 and covering the saw blade 3, and one end of the dust cover 7 is rotatably connected to the worktable.
