Description

Technical Field

[0001] The invention relates to the technical field of construction, in particular to a dust-proof crushing device for recycling construction waste stones. Background Art

[0002] Construction waste stones refer to various stone wastes generated during the construction process, including but not limited to concrete blocks, brick and tile fragments, stone scraps, etc. If these waste stones are not processed, they will not only occupy a large amount of land resources, but also pollute the environment. Therefore, how to effectively recycle and reuse these waste stones has become an urgent problem to be solved in the construction industry.

[0003] According to the patent document: CN218012932U, a dustproof waste anode crushing device relates to the technical field of carbon processing equipment, including a main body, a crushing frame is fixed on the inner wall of the main body, two groups of rollers are rotatably connected inside the crushing frame, the two ends of the rollers are extended to the base rods outside the crushing frame, and two groups of scrapers are slidably connected inside the crushing frame between the two groups of rollers. The utility model cooperates with each other by setting a crushing frame, rollers, base rods, scrapers, telescopic rods, notches and filters. When the rollers roll back and forth to squeeze the waste anodes, the scrapers push the crushed waste anodes to one side, and the rollers block the waste anodes, so that the crushed waste anodes rise to form convex balls, and adhere to the surface inclined with the filter screen, so that the waste anodes that meet the standards can be easily taken out, and at the same time, the waste anodes with large particles are retained in the crushing frame and crushed again to the composite standard.

[0004] During the construction process, when stones are poured into the crushing equipment, a lot of dust will be generated. In order to reduce the dust concentration in the surrounding environment, workers usually install atomizing nozzles around the crushing equipment and use spray technology to reduce dust. However, since the feed port and atomizing nozzle of the crushing equipment are usually directly exposed to the external environment, when the equipment is not running, there is a lot of dust in the air at the construction site, which makes the atomizing nozzle easily affected by wind, causing dust to block the spray hole, thereby affecting the spray effect and limiting the dust reduction effect.

[0005] In addition, the feed port of the crushing equipment is directly exposed to the outside, which may cause objects from the construction site to accidentally fall into the crushing equipment when the equipment is not in use, which may not only damage the equipment but also cause safety accidents. Summary of the invention

[0006] The purpose of the present invention is to provide a dust-proof crushing device for recycling construction waste stones, so as to solve the problem that the feed port and atomizing nozzle of the crushing equipment proposed in the prior art are usually directly exposed to the external environment.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present application can effectively reduce dust pollution generated during the crushing process and improve the cleanliness of the working environment by providing a dust removal trough and an atomizing nozzle connecting mechanism. The setting of the nozzle connecting mechanism can well protect the atomizing nozzle and extend the service life of the nozzle. Specifically, when the waste stone is discharged into the crusher, the hydraulic push rod pushes the push-pull block to rise, and the rotating rod rotates accordingly. The sliding rod slides along the outer wall of the cross bar to move the L-shaped closing plate outward to open the feeding port, and the staff can discharge the stone into the crusher. At the same time, the movement of the L-shaped closing plate drives the connecting plate and the hinged rod to rotate, pushing the nozzle connecting plate and the nozzle to move upward, and the nozzle is exposed and sprays water mist to reduce dust. The spraying range covers the outside of the crusher, and the spraying angle and flow rate are adjustable. After the operation is completed, the hydraulic push rod moves in the opposite direction to close the feeding port, the nozzle descends, and the cover plate is closed to prevent dust from entering the nozzle.

[0022] 2. By setting up an internal dust removal mechanism, the dust generated during the crushing process can be cleaned in time to avoid dust accumulation inside the equipment and ensure the normal operation of the equipment. Specifically, the fan in the exhaust bellows starts working to generate negative pressure, and the dust inside the crusher is sucked into the exhaust plate through the exhaust pipe;

[0023] 3. By setting up an anti-blocking mechanism, the exhaust pipe can be effectively prevented from being blocked, ensuring the smooth operation of the internal dust removal system. Specifically, start the internal dust removal system of the crusher, the motor drives the transmission disc to rotate, and transmits the transmission to the second transmission disc and the rotating rod, pushing the push-pull rotating rod to reciprocate in the U-shaped frame, and the exhaust pipe shakes accordingly to prevent internal dust from being blocked, ensuring a stable exhaust effect.

The tops of the two groups of water pipes 3211 are fixedly connected to the bottom of the nozzle connection plate 3210. The tops of the two groups of nozzle connection plates 3210 are fixedly connected to a plurality of water-passing vertical rods 3212. The tops of the two groups of water-passing vertical rods 3212 extend to the top of the nozzle connection mechanism shell 321 and are fixedly connected to the nozzles 3213. The front and rear sides of the push plate 324 are fixedly connected to the push plate sliders 325. The two groups of push plate sliders 32 5 are extended to the front and rear sides of the outer wall of the nozzle connection mechanism housing 321 through the connecting mechanism slide groove 323, the bottoms of the two groups of push plate sliders 325 are rotatably connected with hinged rods 326, the sides of the two groups of hinged rods 326 away from the push plate sliders 325 are rotatably connected with hinged rod sliders 327, the outer walls of the two groups of hinged rod sliders 327 are slidably connected to the inner wall of the slide groove plate 312, the inner sides of the two groups of hinged rod sliders 327 are fixedly connected with L-shaped connecting plates 328, and the inner sides of the two groups of L-shaped connecting plates 328 are respectively fixedly connected to the outer sides of the two L-shaped closing plates 3115;,

[0038] When it is necessary to discharge the waste stone to the inner wall of the crusher 2, the hydraulic push rod 318 is used to drive the push-pull block 3111 to move toward the top, thereby driving the rotating rod 3112 to rotate. The rotation of the rotating rod 3112 drives the sliding rod 3113 to slide along the outer wall of the cross bar 3110, so that the sliding rod 3113 drives the L-shaped closing plate 3115 to move outward, thereby opening the feed port 313. The staff can use the feed port 313 to put the stone into the crusher 2 for crushing operation;

[0039] At the same time, when the L-shaped closing plate 3115 moves outward, it drives the L-shaped connecting plates 328 on the front and rear sides to slide on the inner wall of the slide plate 312, thereby driving the hinge rod 326 to rotate. The hinge rod 326 rotates to change the angle, thereby pushing the push plate 324 to slide toward the top on the inner wall of the nozzle connecting mechanism shell 321. When the push plate 324 moves toward the top on the inner wall of the nozzle connecting mechanism shell 321, it drives the two push plate connecting vertical rods 329 to push the nozzle connecting plate 3210 to move toward the top, thereby pushing the multiple water-passing vertical rods 3212 and the nozzle 3213 to move toward the top and pushing the cover plate 3215 to rotate, so that the nozzle 3213 is directly exposed to the outside of the nozzle connecting mechanism shell 321 and the dustproof bin 3214.

[0040] When the stone is unloaded, the nozzle 3213 draws water from the inner wall of the water tank 322 through the water pipe 3211, and sprays it out through the nozzle 3213 in an atomized form, thereby effectively reducing the dust generated during the unloading process. The atomized spraying range of the nozzle 3213 covers the entire exterior of the crusher 2, ensuring that the dust is effectively controlled at the beginning of its generation. In addition, the spraying angle and flow rate of the nozzle 3213 can be adjusted according to actual needs to adapt to stone crushing operations of different types and sizes;

[0041] After the crushing operation is completed, the hydraulic push rod 318 moves in the opposite direction, the push-pull block 3111 moves downward, driving the rotating rod 3112 to rotate in the opposite direction, and the sliding rod 3113 slides along the outer wall of the cross bar 3110, so that the L-shaped closing plate 3115 moves inward, thereby closing the feed inlet 313. At the same time, the hinge rod 326 rotates to push the push plate 324 to slide toward the bottom on the inner wall of the nozzle connection mechanism housing 321, and the push plate 324 drives the nozzle connection plate 3210 to move downward, and the water-passing vertical rod 3212 and the nozzle 3213 drop accordingly, and the cover plate 3215 is closed, and the nozzle 3213 is re-enclosed in the dustproof bin 3214 to prevent dust from entering the nozzle 3213 and clogging it.

[0042] The design of the entire dust-proof crushing device fully considers environmental protection and ease of operation. The hydraulic system and mechanical linkage device are used to achieve dust control during the crushing process and automated operation of stone unloading.

The top and bottom of the outer wall of the transmission disc 423 are respectively covered with crawler tracks 424. The inner walls of the two crawler tracks 424 on the side away from the transmission disc 423 are covered with second transmission discs 425. The tops of the two second transmission discs 425 are fixedly connected to rotating rods 426. The tops and bottoms of the inner sides of the two U-shaped hinged frames 422 are rotatably connected to push-pull rotating rods 427. The bottom sides of the two push-pull rotating rods 427 at the bottom are fixedly connected to the rotating rod 426. One end extending to the inner side of the U-shaped hinged frame 422, the inner sides of the two sets of push-pull rotating rods 427 away from the rotating rod 426 are both rotatably connected with the exhaust pipe shaking push-pull rods 428, and the outer sides of the two exhaust pipe shaking push-pull rods 428 are both fixedly connected with exhaust pipe connecting plates 429, and the inner walls of the two exhaust pipe connecting plates 429 are respectively fixedly connected to the outer walls of the two sets of exhaust pipes 413, and the tops and bottoms of the two exhaust pipe connecting plates 429 are both fixedly connected with connecting plate sliding rods 4210, and the outer walls of the two sets of connecting plate sliding rods 4210 are respectively slidably connected to the inner walls of the two sets of sliding groove rods 417;

[0044] In order to prevent the dust on the inner wall of the crusher 2 from being scattered outside during crushing, the internal dust removal mechanism 4 is first started, the motor 421 starts to work, driving the transmission disc 423 to rotate, the rotation of the transmission disc 423 is transmitted to the second transmission disc 425 through the crawler belt 424, and then the rotating rod 426 generates a rotating motion, and the rotation of the rotating rod 426 drives the push-pull rotating rod 427 to reciprocate in the U-shaped hinged frame 422;

[0045] As the push-pull rotating rod 427 reciprocates, the exhaust pipe shaking push-pull rod 428 also reciprocates accordingly, so that the exhaust pipe connecting plate 429 drives the exhaust pipe 413 to reciprocate in the slide slot rod 417. This reciprocating shaking can effectively prevent dust from clogging the exhaust pipe 413, ensuring the continuity and stability of the exhaust effect.

[0046] At the same time, the fan in the exhaust bellows 411 starts to work, generating negative pressure, and the dust inside the crusher 2 is sucked in by the exhaust plate 414 through the exhaust pipe 413;

[0047] Through the coordinated work of the above structures, the dust-proof crushing device can effectively control the diffusion of dust during the crushing process, reduce pollution to the environment, and ensure the smooth progress of the crushing operation.

[0048] Working principle: When it is necessary to discharge the waste stone to the inner wall of the crusher 2, the hydraulic push rod 318 is used to drive the push-pull block 3111 to move to the top, thereby driving the rotating rod 3112 to rotate. The rotation of the rotating rod 3112 drives the slide bar 3113 to slide along the outer wall of the cross bar 3110, so that the slide bar 3113 drives the L-shaped closing plate 3115 to move outward, thereby opening the feed port 313. The staff can discharge the stone through the feed port 313 into the interior of the crusher 2 for crushing. At the same time, when the L-shaped closing plate 3115 moves outward, it also drives the L-shaped The connecting plate 328 slides on the inner wall of the slide plate 312, thereby driving the hinge rod 326 to rotate. The hinge rod 326 rotates to change the angle, thereby pushing the push plate 324 to slide toward the top on the inner wall of the nozzle connection mechanism housing 321. The push plate 324 moves toward the top of the inner wall of the nozzle connection mechanism housing 321, while driving the two push plate connecting vertical rods 329 to push the nozzle connection plate 3210 to move toward the top, thereby pushing the multiple water-passing vertical rods 3212 and the nozzle 3213 to move toward the top and pushing the cover plate 3215 to rotate, so that the nozzle 3213 is directly exposed to the nozzle connection mechanism housing 321. 1 and the outside of the dustproof bin 3214. When the stone is unloaded, the nozzle 3213 draws water from the inner wall of the water tank 322 through the water pipe 3211, and sprays it out through the nozzle 3213, thereby effectively reducing the dust generated during the unloading process. The atomization spraying range of the nozzle 3213 covers the entire outside of the crusher 2, ensuring that the dust is effectively controlled at the beginning of its generation. In addition, the spraying angle and flow rate of the nozzle 3213 can be adjusted according to actual needs to adapt to stone crushing operations of different types and sizes. After the crushing operation is completed, the hydraulic push rod 318 moves in the opposite direction, and the push-pull block 311 1 moves downward, driving the rotating rod 3112 to rotate in the opposite direction, and the sliding rod 3113 slides along the outer wall of the cross rod 3110, so that the L-shaped closing plate 3115 moves inward, thereby closing the feed port 313. At the same time, the hinge rod 326 rotates, pushing the push plate 324 to slide toward the bottom on the inner wall of the nozzle connection mechanism housing 321, and the push plate 324 drives the nozzle connection plate 3210 to move downward, and the water-passing vertical rod 3212 and the nozzle 3213 fall accordingly, and the cover plate 3215 is closed, and the nozzle 3213 is again sealed in the dustproof bin 3214 to prevent dust from entering the nozzle 3213 and clogging it;

[0049] The rotation of the transmission disc 423 is transmitted to the second transmission disc 425 through the crawler belt 424, thereby causing the rotating rod 426 to rotate. The rotation of the rotating rod 426 drives the push-pull rotating rod 427 to reciprocate in the U-shaped hinged frame 422. With the reciprocating motion of the push-pull rotating rod 427, the exhaust pipe shaking push-pull rod 428 also reciprocates accordingly, so that the exhaust pipe connecting plate 429 drives the exhaust pipe 413 to reciprocate in the slide groove rod 417. This reciprocating shaking can effectively prevent the dust inside the exhaust pipe 413 from being blocked, ensuring the continuity and stability of the exhaust effect. At the same time, the fan in the exhaust bellows 411 starts to work, generating negative pressure, and the dust inside the crusher 2 is sucked into the exhaust plate 414 through the exhaust pipe 413.
