DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a dust reduction structure for a mineral processing machine includes a box body 1, a feed hopper is fixedly installed on the upper right part of the box body 1, a screening component 2 is fixedly installed at the bottom position of the left and right parts of the inner wall of the box body 1, a dust reduction component 3 is fixedly installed on the top right side of the box body 1, and a cleaning component 4 is fixedly installed on the upper end of the dust reduction component 3.

[0028] The ore particles of different sizes can be classified and collected by the screening assembly 2, and the vibration of the screen plate 22 can make the screening effect obvious, while reducing the possibility of blockage of the three screen areas 24. When the screen plate 22 vibrates, the plurality of material-dispensing plates 211 drive the ore material to move quickly on the guide plate 21, which can prevent the area below the feed hopper and between the guide plates 21 from being blocked. The dust-reducing assembly 3 can absorb the dust generated in the box 1, and the cleaning assembly 4 can scrape the dust on the two filter plates 33, and make the dust enter the collection box 46 through the two chutes 45.

[0029] like Figure 4 As shown, the screening assembly 2 includes a guide plate 21, the front and rear sides of the guide plate 21 are fixedly installed at the top position of the front and rear parts of the inner wall of the box body 1, the guide plate 21 is located below the feed hopper, and a sieve plate 22 is rotatably connected to the bottom position of the right part of the inner wall of the box body 1, and two spacer layers 23 are arranged at the upper end of the sieve plate 22. The two spacer layers 23 divide the sieve plate 22 into three screen areas, and three material receiving boxes matching the screen areas 24 are slidably connected to the bottom of the inner wall of the box body 1, and a box door 1 is hinged at the bottom of the front side of the box body 1.

[0030] Ore particles fall from the feed hopper onto the guide plate 21, which is set at an angle. The ore particles then fall onto the screen plate 22. The mesh openings of the three screen areas 24 increase from left to right. The ore is screened and falls into three receiving boxes in turn. Door 1 is located in front of the three receiving boxes, and door 1 can be opened later to process the three receiving boxes.

[0031] like Figure 4 As shown, a mounting plate 25 is fixedly installed at the bottom position of the left part of the inner wall of the box body 1 , and a plurality of linearly arranged springs 26 are fixedly installed at the upper end of the mounting plate 25 , and the upper ends of the plurality of springs 26 are fixedly connected to the lower end of the sieve plate 22 .

[0032] When the ore particles fall onto the screen plate 22, the screen plate 22 is in an inclined state due to the position setting of the mounting plate 25. The elastic potential energy of the plurality of springs 26 can not only protect the three screen areas, but also the plurality of springs 26 can enhance the vibration effect of the screen plate 22 by cooperating with the cam 28, so that the ore particles can be screened more fully.

[0033] like Figure 2 and Figure 4 As shown, a motor 27 is fixedly installed on the left rear side of the box body 1 , the outer wall of the output end of the motor 27 passes through the rear part of the box body 1 and is fixedly installed with a cam 28 , and the outer surface of the cam 28 abuts against the lower left part of the sieve plate 22 .

[0034] The cam 28 can be driven to rotate through the output end of the motor 27, and the cam 28 drives the screen plate 22 to vibrate back and forth through a plurality of springs 26, thereby enhancing the screening effect.

[0035] like Figure 3 and Figure 4 As shown, the rear part of the outer wall of the output end of the motor 27 is movably connected to a transmission mechanism 29, and the right position of the top of the rear side of the box body 1 is rotatably connected to a rotating shaft 210 that passes through the rear part of the box body 1. The rear part of the outer wall of the rotating shaft 210 is movably connected to the transmission mechanism 29, and a plurality of material shifting plates 211 arranged in a ring form are fixedly installed in the middle part of the outer wall of the rotating shaft 210, and the plurality of material shifting plates 211 are located above the guide plate 21.

[0036] The transmission mechanism 29 is a common mechanism, which includes two pulleys and a belt. The two pulleys are fixedly sleeved on the rear part of the outer wall of the output end of the motor 27 and the rear part of the outer wall of the rotating shaft 210 respectively. The belt is connected to the outer surface of the two pulleys for transmission. When the pulley at the bottom rotates, the pulley at the top can drive the rotating shaft 210 to rotate through the belt, and several material-discharging plates 211 push the ore particles toward the screen plate 22.

[0037] like Figure 5 As shown, the dust reduction assembly 3 includes a dust reduction box 31, the left side of the dust reduction box 31 is fixedly installed on the top right side of the box body 1, the rear side of the dust reduction box 31 is hinged with a box door 2, the right side of the dust reduction box 31 is fixedly installed with a negative pressure fan 32, the left and right parts of the inner wall of the dust reduction box 31 are slidably connected with filter plates 33, a conveying pipe 34 is fixedly installed on the top left side of the dust reduction box 31, the side of the conveying pipe 34 away from the dust reduction box 31 passes through the right part of the box body 1 and is fixedly installed with a dust suction pipe 35, and a plurality of dust suction heads 36 arranged in a linear manner are fixedly installed on the bottom of the outer wall of the dust suction pipe 35.

[0038] The negative pressure fan 32 is an existing structure, which sucks the air inside the box 1 into the conveying pipe 34 through a plurality of dust suction heads 36, and then transmits it to the dust reduction box 31 through the conveying pipe 34. The two filter plates 33 in the dust reduction box 31 are air filter plates, which can retain dust, and the clean gas is transmitted to the outside by the negative pressure fan 32.

[0039] like Figure 6 and Figure 7 As shown, the cleaning assembly 4 includes two moving rods 41, the outer walls of the two moving rods 41 pass through the top of the dust reduction box and are fixedly installed with scrapers 42, the upper right parts of the two scrapers 42 are provided with through grooves 43, the right sides of the two scrapers 42 are respectively overlapped with the left sides of the two filter plates 33, and the left and right positions of the bottom of the inner wall of the dust reduction box 31 are provided with inclined grooves 45, the two inclined grooves 45 are located above the two scrapers 42, and the left and right parts of the lower end of the dust reduction box 31 are fixedly installed with openable collecting boxes 46, and the two collecting boxes 46 are connected with the two inclined grooves 45.

[0040] The two moving rods 41 are moved, and the two moving rods 41 drive the corresponding scrapers 42 to act on the surface of the filter plate 33, and the dust on the filter plate 33 is scraped off and falls into the inclined groove 45 through the through groove 43, and then is introduced into the two collection boxes 46 through the two inclined grooves 45. The bottom of the inner wall of the two collection boxes 46 is connected with a box cover that can be plugged in and out. When it is necessary to clean the dust, just pull out the two box covers.

[0041] like Figure 7 As shown, the upper ends of the two moving rods 41 are fixedly installed with a top plate 44, the upper front part of the dust suppression box 31 is fixedly installed with a mounting frame 47, the inner wall of the mounting frame 47 is fixedly installed with a slide rod 48, the outer wall of the slide rod 48 is slidably connected with a fixing frame 49, the rear lower end of the fixing frame 49 overlaps with the upper end of the top plate 44, the front part of the outer wall of the slide rod 48 is movably sleeved with a return spring 410, the front end of the return spring 410 is fixedly connected to the front part of the inner wall of the mounting frame 47, and the rear end of the return spring 410 is fixedly connected to the front bottom of the fixing frame 49.

[0042] By moving the fixing frame 49, the fixing frame 49 is moved on the sliding rod 48. When the fixing frame 49 is away from the top plate 44, the two moving rods 41 can be brought into contact and fixed state. After releasing the fixing frame 49, the elastic restoring force of the reset spring 410 drives the fixing frame 49 to reset and limit the top plate 44 again.

[0043] The working principle of the utility model is as follows: the feed hopper needs to be connected to the discharge port of the ore dressing machine, and the ore particles enter the box body 1 from the feed hopper, and before this, the motor 27 and the negative pressure fan 32 are started.

[0044] Ore particles fall obliquely from the guide plate 21 onto the screen plate 22, and the three screen areas 24 screen particles of different sizes, and the sorted ore materials fall into the material receiving box, and the box door can be opened later to slide the three material receiving boxes out of the box body 1. The output end of the motor 27 drives the cam 28 to rotate, and the cam 28 acts on the lower surface of the screen plate 22 to achieve a better material screening effect. At the same time, the transmission mechanism 29 transmits the rotation of the output end of the motor 27 to the rotating shaft 210, and the rotating shaft 210 drives a plurality of material-diverting plates 211 to rotate, and the plurality of material-diverting plates 211 can prevent the area between the guide plate 21 and the feed hopper from being blocked due to rapid feeding.

[0045] Through the negative pressure fan 32, several dust suction heads 36 suck the dust in the box body 1 into the dust reduction box 31 through the conveying pipe 34 and the dust suction pipe 35, and the two filter plates 33 filter the dust in the gas, and the dust remains on the surface of the two filter plates 33. The clean gas is transported to the outside by the negative pressure fan 32.

[0046] When the two filter plates 33 need to be cleaned, the negative pressure fan 32 is closed, the fixing frame 49 is pulled, and the return spring 410 accumulates elastic potential energy under the extrusion force, and then the two moving rods 41 are pulled back and forth, so that the two moving rods 41 drive the scraper 42 to scrape the dust on the filter plate 33, and the dust falls from the two through grooves 43 into the two inclined grooves 45, and then the dust enters the collection box 46 from the inclined grooves 45 for collection. When not in use, the top plate 44 is loosened, so that the two scrapers 42 are located at the bottom of the inner cavity of the dust reduction box 31, and the fixing frame 49 is loosened. The return spring 410 instantly releases elastic potential energy to drive the fixing frame 49 to reset. The fixing frame 49 is located above the top plate 44 and clamps the top plate 44, thereby preventing the two moving rods 41 from moving at will when the negative pressure fan 32 is working.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
