It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

Embodiment: As shown in Figures 1-3, the utility model provides a technical solution, a mine stone crushing device with good dust prevention effect, including a stone crusher 1 and a feed hopper 4, the top of the stone crusher 1 is fixedly installed with the feed hopper 4, and one side of the stone crusher 1 is fixedly installed with a stone crushing dust removal component 2, and the stone crushing dust removal component 2 includes a dust removal box 201, a fan 202, a filter 203 and a rotating wheel 204;

A dust removal box 201 is fixedly installed on one side of the stone crusher 1, a fan 202 is fixedly installed on one side of the dust removal box 201, a filter 203 is fixedly installed on one side of the stone crusher 1 at a position equidistant from the fan 202, a rotating wheel 204 is fixedly installed on the outer side of one end of the filter 203, and the input end of the fan 202 is connected to the external electrical output end;

A feed screening assembly 3 is fixedly installed on one side of the feed hopper 4, and the feed screening assembly 3 includes a receiving box 301, a leakage pipe 302, a screening box 303 and a motor rotor 304;

A receiving box 301 is fixedly installed on one side of the feed hopper 4, a leakage pipe 302 is fixedly installed on the bottom of the receiving box 301, a screening box 303 is slidably installed at an equidistant position on the top of the receiving box 301, and motor rotors 304 are fixedly installed on both sides of the receiving box 301.

The gravel dust removal assembly 2 also includes a scraper 205, a dust box 206 and a handle 207;

A scraper 205 is fixedly installed on one side of the rotating wheel 204, a dust box 206 is slidably installed at the bottom of the dust box 201, a handle 207 is fixedly installed on one side of the dust box 206, the scraper 205 is slidably installed on the outside of the filter 203, and the input end of the rotating wheel 204 is connected to the external electrical output end.

The feed screening assembly 3 further includes a first rotating shaft 305, a second rotating shaft 306 and a limiting plate 307;

A first rotating shaft 305 is embedded and rotatably connected to one side of the motor rotor 304, and a second rotating shaft 306 is embedded and rotatably connected to one side of the first rotating shaft 305. Limiting plates 307 are fixedly installed on both ends of the two sides of the receiving box 301. The two second rotating shafts 306 are fixedly connected to the screening box 303, and the limiting plates 307 are slidably connected to the screening box 303.

Working principle of the utility model: the staff starts the crusher 1, and when the crushing work is in progress, turns on the fan 202 and the rotating wheel 204. At this moment, the rotating wheel 204 rotates clockwise. Under the adsorption action of the fan 202, the dust generated in the crusher 1 reaches the dust removal box 201 through the pipeline. Because of the obstruction of the filter 203, the dust is adsorbed on the filter 203. The scraper 205 fixed on the rotating wheel 204 is affected by the rotating wheel 204 and rotates clockwise synchronously to clean the dust adsorbed on the filter 203 by the negative pressure, so that the dust falls into the dust box 206. After the equipment has been running for a period of time, the staff takes out the dust box 206 from the dust removal box 201 through the handle 207, and restores it after the dust is emptied.

The staff puts the ore raw materials into the screening box 303, at which time the motor rotary 304 starts to work, the motor rotary 304 drives the first rotating shaft 305 to move, and the first rotating shaft 305 drives the second rotating shaft 306 to rotate, so that the screening box 303 moves up and down. At this time, the L-shaped limit plate 307 limits the baffle plate on the side of the screening box 303 to prevent the screening box 303 from falling off due to the up and down movement; the ore raw materials vibrate on the screening box 303, and the large pieces of raw materials are synchronously affected by the vibration and the slope of the screening box 303. The large pieces of ore fall into the feed hopper 4 and subsequently enter the crusher 1 for crushing. The small pieces of ore that meet the standards pass through the holes opened on the screening box 303 and fall into the receiving box 301. Subsequently, they are affected by gravity and fall onto the conveyor belt through the leakage pipe 302.

Finally, it should be noted that the above description is only a preferred example of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions recorded in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
