[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] First, workers use cranes or other mechanical equipment to hoist the drive machining component 12 onto the support column 11, allowing the support column 11 to support and limit the drive machining component 12. Then, a pushing component is used to send the support column 11 and the drive machining component 12 on top of the support column 11 into the work box 1. After the drive machining component 12 enters the work box 1, it will be processed. During the processing, noise and dust will be generated, so the drive motor 26 drives the drive shaft 20 to rotate. The rotating drive shaft 20 drives the switching gear 18 to rotate. The gear 18 meshes with the switch plate 13, allowing the switch plate 6 to slide within the water tank 5. A water trough is provided between the water tank 5 and the working box 1. When the switch plate 6 is opened, the water in the water tank 5 flows rapidly from the water trough into the working box 1, forming a water curtain within the working box 1. During the processing of the driven processing component 12, the noise and dust generated during the processing are absorbed by the water curtain, thus reducing noise pollution and dust spillage during the processing of the driven processing component 12. The water in the water tank 5 is replenished through the water inlet pipe 7.

[0029] Please refer to the attached image. Figure 1 , Figure 2 and Figure 4As shown, specifically, a support slide 8 is fixedly connected inside the work box 1; a connecting block 31 is slidably connected inside the support slide 8; a sliding plate 10 is fixedly connected to the top of the connecting block 31; a support column 11 is fixedly connected to the top of the sliding plate 10; two support columns 11 are provided and symmetrically arranged on the top of the sliding plate 10; during operation, the sliding plate 10 slides inside the support slide 8 through the connecting block 31 at the bottom, and the sliding plate 10 moves with the top support column 11 so that the driven processing part 12 can be sent into the work box 1 when processing is required, and then pushed out from the work box 1 after processing is completed.

[0030] Please refer to the attached image. Figure 2 , Figure 5 and Figure 6 As shown, specifically, the drive shaft 20 has threads near the upper support plate 19; a lifting plate 21 is rotatably mounted on the drive shaft 20 within the threaded area; a pressure rod 28 is fixedly connected to the lifting plate 21; a pressure block 30 is fixedly connected to the pressure rod 28; two pressure blocks 30 are provided and symmetrically arranged on the pressure rod 28; a fixing block 23 is fixedly connected to the drive shaft 20; a spring 22 is sleeved on the drive shaft 20; one end of the spring 22 is fixedly connected to the fixing block 23; during operation, the drive shaft 20 rotates, causing the lifting plate 21 in the threaded area to rotate and rise, and the rising and falling lifting plate 21 causes the pressure rod 28 and pressure block 30 to descend, thus setting the descent... The pressure rod 28 and pressure block 30 cooperate with the support column 11 to fix the drive processing part 12 that is fed into the work box 1. This prevents the drive processing part 12 from shaking and falling off during processing. In order to prevent the pressure block 30 from continuously pressing down and damaging the drive processing part 12, the threads on the drive shaft 20 near the drive processing part 12 will be gradually removed. As a result, the descending lifting plate 21 will compress the spring 22. When the drive shaft 20 reverses, the spring 22 will push the lifting plate 21 back up, so that the lifting plate 21 re-engages with the threads on the drive shaft 20, allowing the lifting plate 21 to move upward with the pressure rod 28 and pressure block 30.

Figure 3 and Figure 6 As shown, specifically, a vertical block 17 is fixedly connected to the work box 1; there are two vertical blocks 17, which are symmetrically fixedly installed on the work box 1; a column 16 is fixedly connected to the top of the vertical block 17; a sliding block 15 is fixedly connected to the top of the column 16; a sliding groove 14 is fixedly connected to the bottom of the switch plate 6; the sliding block 15 is slidably installed in the sliding groove 14; during operation, when the switch gear 18 drives the switch gear plate 13 and the switch plate 6 to move, the sliding block 15, column 16 and vertical block 17 on the work box 1 are to ensure that the switch plate 6 remains sufficiently stable during movement, so as to support it and enable the switch plate 6 to slide normally.

[0032] Please refer to the attached image. Figure 2 , Figure 4 and Figure 6 As shown, specifically, a push toothed plate 24 is fixedly connected to one end of the sliding plate 10; a support base 27 is fixedly connected to the support plate 19; the push toothed plate 24 slides on the support base 27; a push gear 25 is fixedly connected to the drive shaft 20; the push gear 25 meshes with the push toothed plate 24; during operation, the drive shaft 20 rotates, causing the push gear 25 on the drive shaft 20 to rotate, the rotating push gear 25 causes the push toothed plate 24 to move, and the moving push toothed plate 24 causes the sliding plate 10 to move, thereby allowing the sliding plate to enter and exit the working box 1. The support base 27 is set to support the push toothed plate 24, so that the push toothed plate 24 can remain stable when moving.

[0033] Please refer to the attached image.

[0035] Please refer to the attached image. Figure 1 , Figure 2 and Figure 6 As shown, specifically, a water collection tank 2 is fixedly connected to the bottom of the working box 1; a drain pipe 3 is fixedly connected to the water collection tank 2; the other end of the support slide 8 is fixedly installed in the water collection tank 2; during operation, when water flows from the water tank 5 to the working box 1 for noise reduction and dust removal, the wastewater will flow into the water collection tank 2, and then be discharged and collected through the drain pipe 3 on the water collection tank 2, and then reused after treatment.

[0036] The working principle of this utility model is as follows: First, workers use a crane or other mechanical equipment to hoist the drive processing component 12 onto the support column 11, allowing the support column 11 to support and limit the drive processing component 12. Then, a pushing component is used to send the support column 11 and the drive processing component 12 on top of the support column 11 into the work box 1.

The water in the water tank 5 is replenished through the water inlet pipe 7.
