The first pump body 7 is connected with an infusion pipe 8 inclined towards the processing table. The end of the infusion pipe 8 is connected with a nozzle 9. The nozzle 9 is located above the drilling table 3. The bottom surface of the bottom plate 1 is connected with a filter box 10 communicated with the opening. Inside the filter box 10, there are a first step 11 and a second step 12 arranged from top to bottom in sequence. The length of the first step 11 is greater than the length of the second step 12. A coarse filter screen 13 is placed on the first step 11, and a fine filter screen 14 is placed on the second step 12 (as Figure 2As shown, the filter holes on the coarse filter screen are larger than those on the fine filter screen.

When the coarse filter screen 13 becomes blocked, it can be taken out through the opening 2 for cleaning. Since the length of the first step 11 is greater than that of the second step 12, when the fine filter screen 14 becomes blocked, first take out the coarse filter screen 13, and then take out the fine filter screen 14 for cleaning, which is very convenient.

[0026] A liquid outlet pipe 15 is connected to the bottom of the filter box 10. A second pump body 16 is connected to the bottom surface of the bottom plate 1.

Next, drive the drilling mechanism to descend through the lifting mechanism and drill the workpiece. While drilling, open the first control valve 30, and the first pump body 7 sprays the coolant in the liquid storage barrel 6 onto the drilling table 3 through the nozzle 9 to cool the drill rod 21 and the workpiece. The coolant enters the opening 2 from the slope on the drilling table 3, and large particle debris is preliminarily filtered out by the coarse filter screen 13, and then fine powder is filtered out by the fine filter screen 14. The filtered coolant then enters the liquid storage barrel 6 through the liquid outlet pipe 15, the second pump body 16, and the circulation pipe 17, realizing recycling, reducing waste, and lowering costs.
