[0025] 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.

[0026] like Figure 1 and Figure 2 As shown, a dust reduction structure of a mining crusher includes a base 1, a crusher body 5 is fixedly installed on the upper right part of the base 1, a pre-treatment filter component 2 is fixedly installed at the front position of the upper left part of the base 1, a cleaning component 3 is movably connected to the top of the pre-treatment filter component 2, and a dust reduction collection component 4 is fixedly installed at the rear position of the upper left part of the base 1.

[0027] The dust generated by the pulverizer body 5 during operation can be sucked into the pretreatment barrel 21 through the pretreatment filter component 2, and then the larger particles in the dust can be retained through the pretreatment of the filter screen 25. The dust particles covered by the suction force on the surface of the filter screen 25 can be removed through the cleaning component 3, which increases the service life of the filter screen 25 and also improves the dust reduction effect of the structure. The fine dust can be treated with water mist through the dust collection component 4, and the fine dust is entrained by the water and falls into the collection box 46, which can fully clean the dust in the pulverizer body 5 and improve the dust reduction effect of the structure.

[0028] like Figure 3 As shown, the pretreatment filtering assembly 2 includes a pretreatment cylinder 21, a dust reduction box 22 is fixedly installed at the front position of the upper left end of the base 1, the lower end of the pretreatment cylinder 21 is fixedly installed with the upper end of the dust reduction box 22, an air pump 23 is fixedly installed at the middle of the left side of the dust reduction box 22, the input end of the air pump 23 is fixedly connected to the bottom position of the left part of the outer wall of the pretreatment cylinder 21, the output end of the air pump 23 is fixedly connected to the left bottom of the dust reduction box 22, a dust conveying pipe 24 is fixedly installed at the top position of the right part of the outer wall of the pretreatment cylinder 21, and the end of the dust conveying pipe 24 away from the pretreatment cylinder 21 is fixedly connected to the left side of the crusher body 5.

[0029] The air pump 23 is an existing structure, which sucks the dust particles generated in the pulverizer body 5 into the pre-treatment cylinder 21 through the dust conveying pipe 24, wherein the end of the dust conveying pipe 24 away from the pre-treatment cylinder 21 extends into the pulverizing chamber of the pulverizer body 5. Large dust particles are filtered by the filter 25, and fine dust is then transported by the air pump 23 to the dust reduction box 22 for secondary treatment.

[0030] like Figure 3 As shown, a conical filter screen 25 is fixedly installed in the middle of the inner wall of the pretreatment cylinder 21 , and the filter screen 25 is located between the left part of the dust conveying pipe 24 and the input end of the air pump 23 .

[0031] The filter screen 25 can remove larger particles in the dust, while smaller dust flows into the dust suppression box 22 .

[0032] like Figure 4As shown, the cleaning assembly 3 includes a rotating shaft 31, the lower end of the rotating shaft 31 is rotatably connected to the bottom of the inner wall of the pretreatment cylinder 21, the top of the outer wall of the rotating shaft 31 passes through the top of the pretreatment cylinder 21 and is fixedly installed with a turntable 32, and a plurality of scrapers 33 arranged in a ring form are fixedly installed in the middle of the outer wall of the rotating shaft 31, and the lower ends of the plurality of scrapers 33 overlap with the upper surface of the filter screen 25.

[0033] The rotating disk 32 can drive the rotating shaft 31 and a plurality of scrapers 33 to rotate on the upper surface of the filter screen 25 . The plurality of scrapers 33 are made of rubber and can scrape off the dust particles covered on the surface of the filter screen 25 , thereby increasing the service life of the filter screen 25 .

[0034] like Figure 4 and Figure 5 As shown, an arc-shaped discharge chute 34 is opened in the middle position of the rear part of the outer wall of the pretreatment cylinder 21, and the discharge chute 34 is located above the filter 25. An adjusting screw 35 is threadedly connected to the rear part of the outer wall of the pretreatment cylinder 21. The lower end of the adjusting screw 35 is rotatably connected to a sealing plate 36, and the sealing plate 36 is located behind the discharge chute 34. Limit rods 37 are fixedly installed at the left and right positions of the rear part of the outer wall of the pretreatment cylinder 21, and the inner walls of the left and right parts of the rear side of the sealing plate 36 are slidably connected to the outer walls of the two limit rods 37.

[0035] By rotating the adjusting screw 35, the adjusting screw 35 is threadedly connected to the rear part of the outer wall of the pre-treatment barrel 21 to drive the blocking plate 36 to move upward, so that the discharge trough 34 is exposed. When the discharge trough 34 is exposed, the plurality of scrapers 33 are rotated to send the dust particles out of the pre-treatment barrel 21. When cleaning the filter 25, a receiving structure needs to be arranged below the discharge trough 34 to facilitate receiving the dust particles. At the same time, when the blocking plate 36 moves, the two limiting rods 37 play a limiting role in its movement.

[0036] like Figure 5 As shown, a mounting frame 38 is fixedly installed on the left upper end of the pretreatment cylinder 21, a sliding rod 39 is fixedly installed on the inner wall of the mounting frame 38, a sliding block is slidably connected to the outer wall of the sliding rod 39, a fixing rod 310 is fixedly installed on the upper end of the sliding block, an arc-shaped groove is opened on the left upper end of the turntable 32, and the right outer wall of the fixing rod 310 abuts against the right inner wall of the arc-shaped groove.

[0037] The fixing rod 310 is stuck in the arc groove by the elastic restoring force of the spring 311. When the turntable 32 needs to be rotated, the slider is moved to slide on the slide rod 39 and drive the fixing rod 310 away from the turntable 32, so that the fixing state of the turntable 32 can be released.

[0038] like Figure 5 As shown, a spring 311 is movably sleeved on the left portion of the outer wall of the slide bar 39 , the right end of the spring 311 is fixedly connected to the left side of the slide block, and the left end of the spring 311 is fixedly connected to the left portion of the inner wall of the installation frame 38 .

[0039] A through slot is provided at the front right part of the installation frame 38, and a connecting frame is slidably provided on the inner wall of the through slot. The connecting frame is fixedly connected to the slider, and the connecting frame can drive the slider to move. The connecting frame is a U-shaped structure, and the right side of the left part can be stuck on the left side of the installation frame 38, so the operator does not need to always pull the connecting frame to control the position of the fixing rod 310. When the slider and the fixing rod 310 move, the spring 311 is subjected to a squeezing force. After the connecting frame is released, the elastic restoring force of the spring 311 can drive the slider and the fixing rod 310 to quickly reset and clamp the turntable.

[0040] like Figure 6 As shown, the dust collection assembly 4 includes a water tank 41 to which water can be added, the lower end of the water tank 41 is fixedly installed at the rear position of the left upper end of the base 1, a water pump 42 is fixedly installed at the front upper end of the water tank 41, an atomizer 43 is fixedly installed at the output end of the water pump 42, the output end of the atomizer 43 passes through the rear of the dust reduction box 22 and is fixedly installed with a connecting pipe 44, a plurality of linearly arranged spray heads 45 are fixedly installed at the front of the outer wall of the connecting pipe 44, a collecting box 46 is slidably connected to the bottom of the inner wall of the dust reduction box 22, and a box door is hinged at the front bottom of the dust reduction box 22.

[0041] A water supply pipe is fixedly installed at the rear of the upper end of the water supply tank 41. The water pump 42 pumps out the water in the water tank 41. The water flow is converted into mist through the atomizer 43. The mist acts on the fine dust in the dust reduction box 22 through a plurality of spray heads 45. The fine dust is pumped from the pretreatment cylinder 21 into the dust reduction box 22 by the air pump 23. The mist contacts the fine dust, and the two contact and adhere to each other and fall into the collection box 46. Later, you only need to open the box door and slide out the collection box 46 to clean the adhesion of dust and water.

[0042] The working principle of the utility model is as follows: the staff first adds an appropriate amount of water into the water tank 41, and turns on the air pump 23 and the water pump 42 while the grinder body 5 is working. The air pump 23 pumps the dust in the grinder body 5 into the pretreatment cylinder 21 through the dust conveying pipe 24. The dust is intercepted by the filter 25, and the larger dust particles remain on the upper surface of the filter 25, while the fine dust enters the dust reduction box 22. The water pump 42 pumps water out of the water tank 41 into the atomizer 43. The atomizer 43 converts the water into mist. The mist acts on the fine dust, and the mist envelops the dust and falls into the collection box 46.

[0043] After a period of time, the air pump 23 is turned off, and the adjusting screw 35 is rotated to move the sealing plate 36 upward and away from the discharge chute 34, pushing the connecting frame, which drives the slider to move to the left, and clamps its left right side on the left side of the mounting frame 38. The slider drives the fixing rod 310 to disengage from the arc groove. At this time, the spring 311 accumulates elastic potential energy under the extrusion force, and the turntable 32 is rotated. The turntable 32 drives the rotating shaft 31 to rotate, and several scrapers 33 scrape off the dust particles covering the surface of the filter screen and discharge them to the outside of the pretreatment cylinder 21 through the discharge chute 34. Before discharging, a material receiving structure needs to be placed under the discharge chute 34.

[0044] After cleaning the filter 25, the connecting frame and the slider are loosened, and the spring 311 releases the elastic potential energy to drive the slider and the fixing rod 310 to reset, and the fixing rod 310 fixes the rotating shaft 31 and the scraper 33 again to prevent the scraper 33 from rotating and hindering the operation of the filter 25 when the air pump 23 is running. Finally, the box door is opened, and the collection box 46 is slid out to clean the dust and water mixture.

[0045] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
