[0024] When milling holes in the grate plate, place the grate plate on the workbench 1, and then start the hydraulic telescopic rods on both sides to work, that is, the clamping plates connected to the hydraulic telescopic rods will start to tightly clamp the left and right sides of the grate plate, achieving the purpose of clamping and fixing the grate plate. Because a first threaded hole is provided at the middle position of the first moving component 3, and the first moving component 3 is connected to a first screw rod arranged on the support plate 2 through the threaded hole. A second screw rod is rotatably arranged on the first moving component 3, and a second threaded hole is provided on the second moving component 4, and the second moving component 4 is connected to the second screw rod through the threaded hole. Start the motor connected to the first screw rod to work. At this time, the first screw rod starts to rotate. As the first screw rod rotates, the first moving component 3 starts to move back and forth, thereby adjusting the position of the milling hole back and forth. When the position of the milling hole needs to be adjusted left and right, start the motor connected to the second screw rod to work. At this time, the second screw rod starts to rotate, that is, the second moving component 4 starts to move left and right, that is, change the position of the milling hole left and right, so as to ensure that holes are opened at the corresponding positions on the grate plate according to requirements.

[0025] A protective cover 7 is fixedly arranged at the upper end of the movable plate 6. A driving motor 8 is fixedly arranged at the upper end of the protective cover 7. The output end of the driving motor 8 is connected to a negative pressure fan blade 9 through a rotating shaft. A milling hole rod 10 is coaxially and fixedly arranged on the negative pressure fan blade 9. A gear set 11 is fixedly arranged on the rotating shaft installed at the output end of the driving motor 8. The lower end of the movable plate 6 is fixedly arranged with a suction plate 12 through a long rod. A filtering component 15 is arranged on the inner surface of the suction plate 12. A connecting component 16 is arranged at the upper end of the suction plate 12. An air suction pipe 13 is fixedly arranged through the upper end of the connecting component 16, and the air suction pipe 13 is fixedly arranged through the protective cover 7. An adsorbing component 14 is fixedly arranged at the lower end of the suction plate 12; Dense air-permeable holes are formed in the upper end of the protective cover 7. Two groups of air suction pipes 13 are symmetrically arranged on the front and rear sides of the protective cover 7, and each group has a total of three air suction pipes 13; The gear set 11 is composed of two meshing gears, and both gears are coaxially connected to the milling hole rod 10, and the lower end of the milling hole rod 10 is conical; The filtering component 15 includes a fixing plate 151 and a filtering plate 152. The fixing plate 151 is fixedly installed on the inner surface of the suction plate 12, and the lower end of the filtering plate 152 is attached to the upper end of the fixing plate 151; The connecting component 16 includes a connecting sleeve 161, a fixing screw 162 and a connecting nut 163. The connecting sleeve 161 is attached to the suction plate 12, the inner surface of the connecting sleeve 161 is in close contact with the filtering plate 152, the fixing screw 162 is fixedly installed on the suction plate 12, the fixing screw 162 is attached to the connecting sleeve 161, and the connecting nut 163 is threadedly connected to the fixing screw 162.

[0026] As the need to mill holes in the grate plate arises, the drive motor 8 starts to operate. Since the output end of the drive motor 8 is connected to a rotating shaft, and a negative pressure fan blade 9, a hole milling rod 10, and a gear set 11 are installed on the rotating shaft, at this time, as the hole milling rod 10 rotates, the hole milling of the grate plate begins. At the same time, the electric telescopic rod 5 starts to move downward, so as to adjust the depth of the hole milling. During the hole milling, a large amount of dust and waste chips will be generated. At this time, as the negative pressure fan blade 9 rotates, a negative pressure begins to be generated at the lower end inside the protective cover 7 (when the negative pressure fan blade 9 rotates, it blows air outside the protective cover 7). At this time, the adsorbing member 14 begins to adsorb the air around the hole milling, that is, the air enters the lower end of the protective cover 7 through the air suction plate 12 and the air suction pipe 13, and then is blown out of the protective cover 7 by the negative pressure fan blade 9. As the air enters the air suction plate 12, the air passing through can be filtered under the action of the filter plate 152, that is, the purpose of filtering the dust and waste chips in the air is achieved, so as to effectively avoid dust and impurities from entering the surrounding air. When the filter plate 152 needs to be disassembled and replaced, rotate the connecting nut 163, and the connecting nut 163 begins to move away from the fixing screw 162 until the connecting nut 163 is no longer connected to the fixing screw 162. Then pull the connecting sleeve 161, and the connecting sleeve 161 begins to move away from the air suction plate 12. At this time, the filter plate 152 can be pulled out to achieve the purpose of replacing or cleaning the filter plate 152.
