[0030] like Figure 2 , Figure 4 and Figure 5As shown, the multi-stage screening mechanism 2 includes a vibration motor 201, an extension plate 202, a spring 203, a support frame 204, a slide 205, a first screen 206, a second screen 207 and a third screen 208. The vibration motor 201 is bolted to one side of the screening frame 1, and the plurality of extension plates 202 are respectively fixedly connected to the opposite sides of the screening frame 1. The plurality of springs 203 are respectively arranged at the bottom of the plurality of extension plates 202, and the support frame 204 is arranged at the bottom of the spring 203. , multiple slide grooves 205 are all opened inside the screening frame 1, and the two ends of the first screen 206, the second screen 207 and the third screen 208 are respectively slidably connected to the inner walls of the multiple slide grooves 205, and the first screen 206, the second screen 207 and the third screen 208 are all bolted to the screening frame 1. The mesh numbers of the first screen 206, the second screen 207 and the third screen 208 increase successively, and the first screen 206, the second screen 207 and the third screen 208 are all inclined. When in use, the first screen 206, the second screen 207 and the third screen 208 are slid into the slide 205 in turn and fixed to the screening frame 1 by external bolts, which can be convenient for the staff to replace according to different ores; starting the vibration motor 201 and using it in conjunction with the spring 203 can make the screening frame 1 vibrate and reduce the impact of the vibration motor 201 on the support frame 204; when the ore to be screened enters the screening frame 1, it will first fall on the first screen 206. Since the apertures of the first screen 206, the second screen 207 and the third screen 208 become smaller in turn, ores of different sizes can be screened.

[0031] like Figure 4 and Figure 5 As shown, the dust reduction component 3 includes a fixed plate 301, a water tank 302, a water pump 303, an extraction pipe 304, a spray pipe 305, a leakage hole 306 and a water injection pipe 307.

The second conveyor belt 403 is arranged on the inner wall of the extension frame 401. The higher end of the first conveyor belt 402 is located above the conveying start end of the second conveyor belt 403. The conveying directions of the first conveyor belt 402 and the second conveyor belt 403 are consistent. The first conveyor belt 402 and the second conveyor belt 403 are both connected to an external power supply and started. Since the first conveyor belt 402 is obliquely arranged, the ore piled up in a low place can be conveyed to the second conveyor belt 403, and the second conveyor belt 403 can directly convey the ore to the first screen 206 for screening, which reduces manpower operation and improves work efficiency.

Through the sewage pipe 12, the sewage in the collection box 9 can be discharged in time, which is convenient for the staff to handle the sewage.

[0037] The vibration motor 201, the water pump 303 and the conveyor belt motor on the transmission assembly 4 are all electrically connected to the control box.

[0038] Specifically, when the multi-stage vibrating screening machine for ore selection is used: the first screen 206, the second screen 207 and the third screen 208 are sequentially slid into the slide 205, and fixed to the screening frame 1 by external bolts, which can be convenient for the staff to replace according to different ores; the first conveyor belt 402 and the second conveyor belt 403 are connected to the external power supply and started. Since the first conveyor belt 402 is inclined, the ore accumulated at a low place can be transported to the second conveyor belt 403, and the second conveyor belt 403 can directly transport the ore to the first screen 206 for screening; the vibration motor 201 is started, and used in conjunction with the spring 203, the screening frame 1 Vibration occurs and the influence of the vibration motor 201 on the support frame 204 is reduced; when the ore to be screened enters the screening frame 1, it will first fall on the first screen 206. Since the apertures of the first screen 206, the second screen 207 and the third screen 208 become smaller in sequence, ores of different sizes can be screened, and the screened ores will be transmitted respectively through the first guide frame 5, the second guide frame 6 and the third guide frame 7, so as to facilitate collection by the staff; when the ore is screened, the water pump 303 is started, and the water in the water tank 302 is pumped out through the extraction pipe 304, and sprayed on the ore being screened after passing through the leakage hole 306 after the spraying pipe 305, so as to reduce dust.
