The outer surfaces of the return pipe 902 and the connecting pipe 905 are equipped with water pumps 908. The set recycling structure can filter and purify the washing wastewater containing metal scraps, and then drive the water pump 908 to return it to the water storage tank 901, forming a closed-loop water circulation system, thereby effectively reducing the equipment's dependence on external water sources. The filter assembly 903 includes a housing 9031, which is installed inside the mounting groove 103. One end of the housing 9031 is provided with a water inlet, and one end of the return pipe 902 is installed inside the water inlet. A cylinder 9032 is installed on the upper surface of the housing 9031, and a filter element 9033 is installed inside the housing 9031. Several water inlet holes 9034 are opened on the outer surface of the cylinder 9032, and a connecting assembly 909 is installed on the outer surface of the cylinder 9032. The flushing nozzle 11 is connected to the water storage tank 901 through the telescopic pipe 907 and the U-shaped pipe 906. The flexible connection design of the telescopic pipe 907 and the U-shaped pipe 906 allows the flushing nozzle 11 to move synchronously with the drill rod 7 as it rises and falls, ensuring that the flushing range always covers the drilling area. After the water pump 908 is started, the clean water in the water storage tank 901 is pumped into the flushing nozzle 11 through the connecting pipe 905 to flush the drilling area. Then, the wastewater containing metal debris flows into the collection tank 102 through the placement tank 101. After the filter screen 8 intercepts large particles of debris, the wastewater enters the filter assembly 903 in the installation tank 103. The wastewater enters the outer shell 9031 through the water inlet hole 9034 of the cylinder 9032. After being filtered by the filter element 9033, the purified water returns to the water storage tank 901 through the return pipe 902 driven by the water pump 908, forming a closed-loop water circulation. Through the dual filtration of the filter screen 8 and the filter element 9033, the purification and recycling of flushing water is achieved, reducing the external water supply demand. The connecting assembly 909 includes a connecting block 9091, which is installed on the outer surface of the cylinder 9032.

One end of the limiting rod 9097 passes through the connecting block 9091 and is installed inside the limiting hole 105. By moving the lever 9096 on the cover plate 9095, the slider 9093 slides along the groove 9092 and compresses the spring 9094, causing the limiting rod 9097 to disengage from the limiting hole 105 of the groove 104. Then, the connecting block 9091 is pulled out horizontally from the groove 104, and the cylinder 9032 can be taken out from the outer shell 9031. This makes it easier for the staff to take out the filter element 9033 from the outer shell 9031 and replace it, thus achieving the effect of easy replacement. The movable structure 5 includes a support frame 501. The output end of the hydraulic cylinder 4 is mounted on the upper surface of the support frame 501. A one-way screw 502 is rotatably connected to the inner surface of the support frame 501. One end of the one-way screw 502 passes through the support frame 501 and is mounted with a driven wheel 503. A second motor 504 is mounted on the upper surface of the support frame 501. A drive wheel 505 is mounted on the output end of the second motor 504. The drive wheel 505 is connected to the driven wheel 503 via a belt 506. A placement seat 507 is threaded onto the outer surface of the one-way screw 502. A first motor 6 is mounted inside the placement seat 507. A guide rod 508 is installed on the inner surface of the support frame 501, and the placement seat 507 is slidably connected to the outer surface of the guide rod 508. A through hole is opened on the upper surface of the top plate 3, and an auxiliary rod 509 is slidably connected inside the through hole. One end of the auxiliary rod 509 is installed on the upper surface of the support frame 501. The hydraulic cylinder 4 is activated, causing its output end to drive the support frame 501 to descend vertically to the initial height. Then, the second motor 504 drives the drive wheel 505 to rotate, which in turn drives the driven wheel 503 and the one-way screw 502 to rotate synchronously via the belt 506. This causes the threaded placement seat 507 to move horizontally along the guide rod 508, thereby driving the first motor 6 and the drill rod 7 to be precisely positioned at the target processing point. After processing is completed, the second motor 504 reverses to return the placement seat 507 to its original position. At the same time, the hydraulic cylinder 4 lifts the support frame 501 to reset, and the auxiliary rod 509 slides in the through hole of the top plate 3 to maintain the stability of the lifting and lowering of the support frame 501.

[0020] In use, firstly, a certain amount of water is injected into the water storage tank 901 through the water inlet pipe 904. Then, the parts are placed inside the placement slot 101. After that, the hydraulic cylinder 4 is started, and its output end drives the support frame 501 to descend vertically to the initial height. Then, the second motor 504 drives the drive wheel 505 to rotate, which drives the driven wheel 503 and the one-way screw 502 to rotate synchronously via the belt 506. This causes the threaded placement seat 507 to move horizontally along the guide rod 508, thereby driving the first motor 6 and the drill rod 7 to be precisely positioned to the target processing point. Then, the first motor 6 is started, and its output end drives the drill rod 7 to rotate. Then, the hydraulic cylinder 4 is operated, and its output end continues to push the support frame 501 to descend vertically, so that the drill rod 7 drills the parts. After the processing is completed, the second motor 504 reverses to make the placement seat 507 return to its original position. At the same time, the hydraulic cylinder 4 lifts the support frame 501 to reset. The auxiliary rod 509 slides in the through hole of the top plate 3 to maintain the stability of the lifting of the support frame 501. During the drilling process of the parts, the flushing nozzle 11 is connected to the water storage tank 901 through the telescopic pipe 907 and the U-shaped pipe 906. The flexible connection design of the telescopic pipe 907 and the U-shaped pipe 906 allows the flushing nozzle 11 to move synchronously with the drill rod 7, ensuring that the flushing range always covers the drilling area. After the water pump 908 is started, the clean water in the water storage tank 901 is pumped into the flushing nozzle 11 through the connecting pipe 905 to flush the drilling area. Afterwards, the wastewater containing metal debris is placed in the placement tank 1. 01 The wastewater flows into the collection tank 102. After large particles are intercepted by the filter screen 8, the wastewater enters the filter assembly 903 of the installation tank 103. The wastewater enters the outer shell 9031 through the water inlet 9034 of the cylinder 9032. After being filtered by the filter element 9033, the purified water returns to the water storage tank 901 through the return pipe 902 driven by the water pump 908, forming a closed-loop water circulation. Through the dual filtration of the filter screen 8 and the filter element 9033, the purification and recycling of the flushing water is achieved, reducing the external water supply demand. When the filter element 9033 needs to be replaced, the filter screen 8 is removed from the collection groove 102, exposing the installation groove 103. Then, by moving the lever 9096 on the cover plate 9095, the slider 9093 slides along the groove 9092 and compresses the spring 9094, causing the limiting rod 9097 to disengage from the limiting hole 105 of the groove 104. Subsequently, the connecting block 9091 is horizontally pulled out from the groove 104, and the cylinder 9032 can be removed from the outer shell 9031. This makes it easier for the staff to remove the filter element 9033 from the outer shell 9031 for replacement, achieving the effect of convenient replacement.
