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 refers 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 cause environmental pollution. 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 dust-proof 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 sets of pressure rollers are rotatably connected inside the crushing frame, the two ends of the pressure rollers are extended to the base rods outside the crushing frame, and two sets of scrapers are slidably connected inside the crushing frame between the two sets of pressure rollers. The utility model cooperates with each other by setting a crushing frame, a pressure roller, a base rod, a scraper, a telescopic rod, a notch and a filter. When the pressure roller rolls back and forth to squeeze the waste anode, the scraper pushes the crushed waste anode to one side, and at the same time, the pressure roller blocks the waste anode, so that the waste anode rises after crushing to form a convex ball, and adheres to the surface inclined with the filter screen, so that the waste anode that meets the standard can be easily taken out, and at the same time, the large particles of waste anode are retained in the crushing frame and crushed again to the composite standard.

[0004] During construction, when stone is poured into crushing equipment, a large amount of dust is generated. 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, because the crushing equipment's feed inlet and atomizing nozzles are usually directly exposed to the external environment, when the equipment is not running, the air at the construction site contains a large amount of dust. This makes the atomizing nozzles susceptible to wind, causing dust to clog the nozzle holes, 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.

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

[0021] 1. The present application is provided with a dust removal chute and an atomizing nozzle connecting mechanism, which can effectively reduce dust pollution generated during the crushing process and improve the cleanliness of the working environment. The setting of the nozzle connecting mechanism ensures that the atomizing nozzle can be well protected and the service life of the nozzle is extended.

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;

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 and ensure stable exhaust effect.

The outer walls of the two L-shaped closing plates 3115 are movably connected to the outer wall of the feed port 313. The two atomizing nozzle connection mechanisms 32 both include nozzles. The connecting mechanism shell 321, the top of the two nozzle connecting mechanism shells 321 are fixedly connected to the dustproof bin 3214, the outer sides of the two dustproof bins 3214 are rotatably connected to the cover plate 3215, the front and rear sides of the two nozzle connecting mechanism shells 321 are provided with a connecting mechanism slide 323, the outer bottom of the two nozzle connecting mechanism shells 321 are fixedly connected to the water tank 322, the inner walls of the two nozzle connecting mechanism shells 321 are slidably connected to the push plates 324, the front and rear sides of the tops of the two push plates 324 are fixedly connected to the push plate connecting vertical rods 329, the tops of the two sets of push plate connecting vertical rods 329 are fixedly connected to the nozzle connecting plates 3210, and the inner walls of the two push plates 324 are fixedly connected to multiple water pipes 3211.The ends of the two groups of water pipes 3211 away from the push plate 324 extend to the outer wall of the nozzle connection mechanism housing 321 and are fixedly connected to the top of the water tank 322. 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 multiple 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 housing 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 slider 325. The two groups of push plate sliders 32 5 extend 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 sets of push plate sliders 325 are rotatably connected to the hinged rod 326. The sides of the two sets of hinged rods 326 away from the push plate slider 325 are rotatably connected to the hinged rod slider 327. The outer walls of the two sets of hinged rod sliders 327 are slidably connected to the inner wall of the slide groove plate 312. The inner sides of the two sets of hinged rod sliders 327 are fixedly connected to the L-shaped connecting plates 328. The inner sides of the two sets 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 waste stones into the inner wall of the crusher 2, the hydraulic push rod 318 is first 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 feeding port 313. The staff can use the feeding port 313 to put stones 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 and changes its 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 nozzles 3213 to move toward the top and pushing the cover plate 3215 to rotate, so that the nozzles 3213 are directly exposed to the outside of the nozzle connection mechanism housing 321 and the dustproof bin 3214.

[0040] When stone is being 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 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, causing the L-shaped closing plate 3115 to move inward, thereby closing the feed inlet 313. At the same time, the hinged rod 326 rotates, pushing the push plate 324 to slide toward the bottom on the inner wall of the nozzle connecting mechanism housing 321. The push plate 324 drives the nozzle connecting plate 3210 to move downward, and the water-passing vertical rod 3212 and the nozzle 3213 drop accordingly. The cover plate 3215 is closed, and the nozzle 3213 is sealed in the dustproof bin 3214 again 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. Through the hydraulic system and mechanical linkage device, dust control during the crushing process and automated operation of stone unloading are achieved.

The inner wall of the two crawlers 424 away from the side of the transmission plate 423 is covered with a second transmission plate 425. The tops of the two second transmission plates 425 are fixedly connected to a rotating rod 426. The top and bottom 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. Extending to one end of 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 side of the rotating rod 426 are rotatably connected to the exhaust pipe shaking push-pull rod 428, and the outer sides of the two exhaust pipe shaking push-pull rods 428 are fixedly connected to the 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 fixedly connected to the 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] During crushing, in order to prevent dust on the inner wall of the crusher 2 from being scattered outside, the internal dust removal mechanism 4 is first started, the motor 421 starts working, driving the transmission plate 423 to rotate, and the rotation of the transmission plate 423 is transmitted to the second transmission plate 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;

[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 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 working, 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 first 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 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 feeding port 313. The staff can discharge the stone into the interior of the crusher 2 through the feeding port 313 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 and changes its 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 nozzles 3213 to move toward the top and pushing the cover plate 3215 to rotate, so that the nozzles 3213 are 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 in atomized form, thereby effectively reducing the dust generated during the unloading process. The atomized 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 the crushing operation of stones of different types and sizes. After the crushing operation is completed, the hydraulic push rod 318 moves in the opposite direction, pushing and pulling the 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 bar 3110, causing the L-shaped closing plate 3115 to move inward, thereby closing the feed port 313. At the same time, the hinged rod 326 rotates, pushing the push plate 324 to slide toward the bottom on the inner wall of the nozzle connection mechanism housing 321. 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. The cover plate 3215 is closed, and the nozzle 3213 is re-enclosed in the dustproof bin 3214 to prevent dust from entering and clogging the nozzle 3213.

[0049] The rotation of the transmission plate 423 is transmitted to the second transmission plate 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 shakes the push-pull rod 428 and also reciprocates accordingly, so that the exhaust pipe connecting plate 429 drives the exhaust pipe 413 to shake back and forth in the slide 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 working, generating negative pressure, and the dust inside the crusher 2 is sucked into the exhaust plate 414 through the exhaust pipe 413.
