As shown in fig. 5, the pumping vane 66 has a disc portion 67, a truncated cone portion 68 and a plurality of flow guiding portions 69, the disc portion 67 is fixedly locked to the second end 484 of the driving shaft 48 connected to the motor 46 through a nut 70, the truncated cone portion 68 is located on a side of the disc portion 67 opposite to the air inlet 432, the truncated cone portion 68 has a flow guiding opening 682, the flow guiding opening 682 is communicated with the opening 454 and is penetrated by the second end 484 of the driving shaft 48 of the motor 46 (as shown in fig. 6), and the flow guiding portions 69 are connected between the disc portion 67 and the truncated cone portion 68 and are rotationally symmetrical relative to the flow guiding opening 682. Thus, when the motor is activated, the second end 484 of the drive shaft 48 drives the pumping blade 66 to rotate, which causes the pumping blade 66 to pump air through the dust collection tube 62 to the dust box 61 and direct the pumped air flow into the exhaust passage 47.

As described above, when the motor 46 is started, as shown in fig. 6 to 8, the motor 46 drives the saw blade 50 at the first end 482 of the driving shaft 48 to perform a sawing operation on a workpiece, and the motor 46 drives the suction blade 66 at the second end 484 of the driving shaft 48 to start a dust collecting operation by the suction blade 66. In the process of performing the sawing operation and the dust collecting operation simultaneously, the sawdust generated during the sawing operation of the workpiece by the saw blade 50 is sucked into the dust box 61 through the inlet 612 after falling into the saw slot 342, the sawdust with a larger volume is collected by an air-permeable dust bag 73 arranged in the dust box 61, the sawdust with a smaller volume and the dust are then passed through the dust bag 73 and reach a filter cartridge 72 arranged in the dust box 61 along with the air flow, the sawdust with a smaller volume and the dust are filtered by the filter cartridge 72, the filtered clean air flow continues to pass through the heat sink 65 from the outlet 614 to the dust pipe 62, then reaches the accommodating space 452 along the dust pipe 62, then flows to the flow guiding parts 69 through the opening 454 and the flow guiding opening 682, and then the air suction blade 66 further guides the air flow into the flow guiding passage 462 through the air inlet 432 by using the flow guiding parts 69 during the operation, the air flow is discharged to the outside through the exhaust ports 442 along the guide passage 462. During the processing, the airflow further carries the heat generated by the heat sink 65 to the dust collecting tube 62 to help the circuit boards 64 to dissipate heat, and the airflow passing through the guiding channel 462 also carries the heat generated by the motor 46 during the operation to the outside through the air outlet 442 to help the motor 46 to dissipate heat.

On the other hand, when the supporting length is to be increased, as shown in fig. 9, the movable platforms 35 can be moved synchronously in a direction away from the saw blade 50 along the longitudinal direction of the saw groove 342 by pulling the holding portion 39 with a force. In the moving process of the movable platforms 35, the saw groove 342 will not move, so that a good sealing effect is still maintained between the middle seat 34 and the dust box 61, the dust will not leak, and the dust collecting efficiency is improved. In addition, in order to keep the movable platforms 35 at the initial position shown in fig. 1, one of the end seats 32 has a screw hole 322, and one end of each movable platform 35 has a pin hole 352, and a safety bolt 71 is screwed into the screw hole 322 and inserted into one of the pin holes 352, as shown in fig. 10, so that the movable platforms 35 cannot move freely and are kept in position, thereby increasing the safety in use.

In summary, the stone cutting machine 10 of the present invention uses the single motor 46 to drive the saw blade 50 and the suction blade 66 simultaneously, so as to perform the sawing operation and the dust collecting operation simultaneously, and not only the overall structure is simplified, but also the processing efficiency is effectively improved. In addition, the design of air circulation can effectively help the circuit board 64 and the motor 46 to dissipate heat during the machining process, so that the stone cutting machine 10 of the utility model achieves the dual effects of dust collection and heat dissipation.
