A vertical rack 29 is fixedly connected to the bottom of the pressure plate 28. An angle rod 30 is rotatably connected to the support plate 8, and a gear 31 is fixedly connected to the angle rod 30. The gear 31 is meshed with the vertical rack 29, and a spray plate 32 is fixedly connected to the angle rod 30. The meshing between the gear 31 and the vertical rack 29 makes the vertical rack 29 drive the gear 31 to rotate reciprocatingly, and the gear 31 drives the spray plate 32 to rotate through the angle rod 30 to reduce dust.

[0041] In this embodiment, a collecting mechanism is provided on the processing seat 5 for collecting dust. The collecting mechanism includes a fan blade 33 fixedly connected to the horizontal plane of the bottom end of the rotating rod 22. An inclined plate 34 is fixedly provided in the processing seat 5.

A box door 40 is provided on the front side of the processing seat 5. The dust box 36 can collect fallen dust.

[0042] The implementation principle of a safety protection device for deep foundation pit excavation of the present application embodiment is as follows: first, start the adjusting motor 4 so that the output shaft of the adjusting motor 4 drives the adjusting screw 18 to rotate. Since the two horizontal plates 21 fixedly connected to the two vertical plates 9 are slidably connected to the two horizontal holes 20, the adjusting screw 18 drives the two adjusting sleeves 19 to move away from or closer to each other, and the two adjusting sleeves 19 drive the two vertical plates 9 to move away from or closer to each other. The two vertical plates 9 drive the two displacement plates 10 to move, which can be adjusted according to the area of ​​the construction site foundation pit 1 so that the two protection plates 17 are located vertically above the two sides of the construction site foundation pit 1. Start the lifting motor 12 so that the output shaft of the lifting motor 12 drives the lifting screw 13 to rotate. Since the lifting plate 16 is slidably connected to the vertical hole 15, the lifting screw 13 drives the lifting sleeve 14 to move downward. The lifting sleeve 14 drives the protection plate 17 to move downward through the lifting plate 16 and is located on the side of the construction site foundation pit 1, thereby achieving a protective effect. When dust is generated during construction in the construction site foundation pit 1, start the lifting motor 12. The processing motor 6 is used so that the output shaft of the processing motor 6 drives the rotating rod 22 to rotate. The meshing between the worm 23 and the worm wheel 25 is used to make the rotating rod 22 drive the worm wheel 25 to rotate through the worm 23. When the worm wheel 25 rotates, the cam 26 can be driven by the horizontal rotating rod 24 to rotate and reciprocate to squeeze the pressing plate 28 downward and compress the reset spring 27. When the reset spring 27 releases its elastic force, it can drive the pressing plate 28 to reset and achieve the effect of reciprocating up and down movement. The pressing plate 28 drives the vertical rack 29 to move up and down, and uses the vertical rack 29 to move up and down. The meshing gears 31 drive the angle rod 30 to rotate reciprocatingly, and the angle rod 30 drives the spray plate 32 to rotate reciprocatingly to reduce dust in the construction site foundation pit 1. At the same time, when the rotating rod 22 rotates, it can drive the fan blades 33 to rotate, and use the negative pressure to generate suction. The dust that has not been processed by the spray plate 32 is sucked into the processing seat 5 through the collecting hole 37. The dust enters the interior of the processing seat 5 along the opening position and is blocked by the blocking net 35. When there is a lot of dust or the fan blades 33 stop working, the dust can fall freely into the dust collecting box 36 for collection.

[0043] Embodiment 2

[0044] The difference between this embodiment and embodiment 1 is that a connecting plate 38 is fixedly connected to one side of the vertical rack 29, and the connecting plate 38 is slidably connected to a side surface of the processing seat 5. A rubber rod 39 is fixedly provided at one end of the top of the connecting plate 38. When the vertical rack 29 moves up and down, the connecting plate 38 can be driven to move up and down, and the rubber rod 39 moves up and down to knock the dust on the blocking net 35, so that the dust can quickly fall into the dust collecting box 36 for collection, and the blocking net 35 is avoided from being blocked. All structures in this application can be selected in terms of material and length according to actual usage. The accompanying drawings are all schematic structural diagrams, and the specific actual dimensions can be appropriately adjusted.

[0045] The above description is only a preferred specific implementation manner of this embodiment, but the protection scope of this embodiment is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme of this embodiment and the inventive concept within the technical scope disclosed in this embodiment, and they should be covered by the protection scope of this embodiment.
