Description

Technical Field

[0001] This invention relates to the field of highway construction technology, specifically to a high-efficiency multi-stage crushing equipment for highway construction. Background Technology

[0002] Highway construction refers to the general work of highway network planning, highway survey and design, highway construction, maintenance and management. During highway construction, stones need to be laid on the roadbed, but the size of the stones cannot be accurately determined, so efficient multi-stage crushing equipment is needed to crush the stones.

[0003] The existing publication number CN114950687B discloses a high-efficiency multi-stage crushing equipment for highway construction, including a crushing device installed in a housing. A triangular block is fixedly connected inside the housing, and an upper crushing roller is rotatably connected inside the housing. The crushing device also includes a V-shaped plate, an inclined block, a scraper, a baffle, and a lower crushing roller. In this high-efficiency multi-stage crushing equipment for highway construction, the initially crushed stones fall onto the triangular block, pressing down on a pusher plate to rotate. The pusher plate rotates downwards, at which point the pull rope is no longer taut, and the rotating plate automatically rotates and opens via a torsion spring. The sliding stones then pass through the opened rotating plate and fall onto the V-shaped plate, thus achieving stone crushing... The intermittent falling of stones prevents too many stones from falling at once, which would result in too many stones landing on the lower crushing roller at once, making it impossible to knock all the stones away and thus improving the secondary crushing effect. However, when the stones fall onto the push plate, the push plate can be opened simultaneously by pulling a rope. The simultaneous opening of the push plate and the rotating plate causes the stones to fall onto the V-shaped plate at the same time, which makes it impossible for the stones to fall intermittently onto the crushing roller. The small discharge port of the V-shaped plate causes the stones to accumulate in the middle of the crushing roller, resulting in a lower stone crushing effect. Furthermore, after the push plate is opened, the stones will fall onto the V-shaped plate first through the push plate, resulting in a low utilization rate of the rotating plate, making it inconvenient for intermittent unloading and resulting in a poor stone crushing effect. Summary of the Invention

[0004] The purpose of this invention is to provide a high-efficiency multi-stage stone crushing device for highway construction. The first baffle plate, the second baffle plate, the rotating cylinder and the holding plate are opened and closed indirectly through the cooperation of a gear set. The indirect opening and closing of the first baffle plate, the second baffle plate, the rotating cylinder and the holding plate will cause the stone to fall onto the stone crushing mechanism indirectly, thereby improving the crushing effect of the stone.

[0038] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0039] 1. A first baffle plate is installed so that after the first feeding port is opened, the stone will fall onto the rotating drum. When the stone on the rotating drum reaches the specified weight, the rotating drum will rotate and pour the stone into the secondary crushing mechanism. At the same time, the rotating drum can drive the receiving plate to rotate and close through the cooperation of the first gear set. At the same time, the receiving plate can drive the second baffle plate to rotate and open the second feeding port through the cooperation of the first gear set. At the same time, the second baffle plate can rotate and close the first feeding port through the cooperation of the first gear set. After the second feeding port is opened, the stone will fall onto the receiving plate. When the stone on the receiving plate reaches the specified weight, it can be rotated to open, so that the stone falls onto the secondary crushing mechanism for crushing. This allows the stone to be crushed intermittently, improves the crushing effect of the stone, and avoids excessive accumulation of stone on the secondary crushing mechanism.

[0040] 2. When the second gear set is in operation, it can drive three reciprocating screws to rotate. When the reciprocating screws rotate, they can drive the actuating frame and the impact rod to move through the cooperation of the parts. When the actuating frame and the impact rod move, they can evenly distribute the falling stones on the rotating cylinder and the holding plate, so that the stones can fall evenly onto the secondary crushing mechanism, thereby improving the crushing effect of the secondary crushing mechanism on the stones.

[0041] 3. When the end of the first push plate is squeezed, it will cause the top arc to squeeze the end of the first push rod. When the end of the first push rod is squeezed, it can cause the first positioning block at the other end to slide in the groove. The sliding of the first positioning block will move out of the bottom of the second blocking plate. When the end of the second push plate is squeezed, it will move upward and push the end of the second push rod through the top arc. When the end of the second push rod is pushed, the other end will cause the second positioning block to slide in the groove. When the second positioning block slides, it will move to the bottom of the first blocking plate for positioning, so that the first and second blocking plates can be prevented from opening when impacted by stones.

[0071] Please see Figures 1-3 This invention provides an embodiment of a high-efficiency multi-stage crushing equipment for highway construction, comprising a crushing box 100, an inlet 200 installed on the top of the crushing box 100, a primary crushing mechanism 300 for initial crushing of the stone fixedly installed inside the crushing box 100 near the inlet 200, a diversion mechanism 400 for batch crushing of the stone fixedly installed in the middle of the inner side of the crushing box 100, the diversion mechanism 400 including a material distribution component and a material discharge component for intermittent feeding of the stone, and a uniform distribution component for uniform material discharge, a secondary crushing mechanism 500 for secondary crushing of the stone installed at the bottom of the crushing box 100 near the diversion mechanism 400, and an outlet 600 opened at the bottom of the crushing box 100 near the secondary crushing mechanism 500.

[0072] It should be understood that the stone to be crushed is poured into the crushing box 100 through the feed inlet 200. After entering the crushing box 100, the stone will fall onto the primary crushing mechanism 300. The primary crushing mechanism 300 performs initial crushing of the stone through the cooperation of the drive component and the crushing cylinder. After the initial crushing, the stone will fall onto the distribution component of the diversion mechanism 400. The distribution component can indirectly convey the crushed stone to the discharge component through the cooperation of the components. When the stone falls onto the discharge component, it can be evenly distributed on the discharge component through the work of the even distribution component. When the stone reaches the specified weight, the stone can be evenly conveyed to the secondary crushing mechanism 500 through the discharge component for secondary crushing. After secondary crushing, the stone can be discharged through the discharge outlet 600.

[0073] like Figure 1 , Figures 4-5 As shown, the diversion mechanism 400 further includes a first gear set 430 for driving the material distribution component and the unloading component to work. The first gear set 430 is composed of multiple sets of gears and toothed belts and other components. It also includes a second gear set 450 for driving the uniform distribution component to rotate. The second gear set 450 is composed of a driving component, multiple sets of gears and toothed belts and other components. It also includes a positioning component for locking the material distribution component.

[0074] It is conceivable that the material distribution component and the unloading component can indirectly unload materials through the cooperation of the first gear set 430, the uniform distribution component can move the stone material through the cooperation of the second gear set 450, and the positioning component can indirectly lock its components when the material distribution component is indirectly unloading materials.

[0075] like Figures 1-6 As shown, the material distribution assembly includes a material distribution frame 410 for diverting the stone to both sides, a first material distribution port 411 and a second material distribution port 414 for discharging the material, and a first baffle plate 413 and a second baffle plate 416 for blocking the material.

[0076] A material distribution frame 410 is fixedly installed on the inner side of the crushed stone box 100. A first material distribution port 411 and a second material distribution port 414 are opened on the left and right sides of the material distribution frame 410. A first baffle plate 413 and a second baffle plate 416 are respectively rotatably installed on the inner side of the first material distribution port 411 and the second material distribution port 414.

[0077] It is worth noting that the first baffle plate 413 and the second baffle plate 416 can be opened and closed indirectly through the cooperation of the first gear set 430. When the first baffle plate 413 opens the first feed port 411, the second baffle plate 416 will close the second feed port 414, and vice versa.

[0078] like Figures 1-6As shown, the unloading assembly includes a discharge rack 420 for unloading materials, and a rotating cylinder 423 and a holding plate 426 for holding stones.

[0079] A discharge rack 420 is fixedly installed at the center of the bottom of the material distribution rack 410. A rotating cylinder 423 is rotatably installed inside the discharge rack 420. A holding plate 426 is rotatably installed inside the crushed stone box 100 on both the left and right sides near the material distribution rack 410.

[0080] It is important to understand that after the first baffle plate 413 opens the first feed inlet 411, the stones will fall onto the rotating drum 423. When the stones on the rotating drum 423 reach the specified weight, the rotating drum 423 will rotate and pour the stones into the secondary crushing mechanism 500. At the same time, the rotating drum 423 can drive the holding plate 426 to rotate and close through the cooperation of the first gear set 430. At the same time, the holding plate 426 can drive the second baffle plate 416 to rotate and open the second feed inlet 414 through the cooperation of the first gear set 430. At the same time, the second baffle plate 416 can drive the first baffle plate 413 to rotate and close the first feed inlet 411 through the cooperation of the first gear set 430. After the second feed inlet 414 is opened, the stones will fall onto the holding plate 426. When the stones on the holding plate 426 reach the specified weight, it can be opened.

[0081] like Figures 1-7 As shown, the uniform distribution assembly includes a reciprocating screw 441 for movement, and a prying frame 443 and an impact rod 448 for uniformly distributing the stone.

[0082] A reciprocating screw 441 is rotatably mounted on each of the left and right sides and the middle of the discharge rack 420 through the mounting cavity. The end of the reciprocating screw 441 passes through the inner wall of the crushing box 100 and is connected to the second gear set 450. A toggle frame 443 is movably mounted on the reciprocating screw 441 on the left and right sides, and an impact rod 448 is movably mounted on the reciprocating screw 441 in the middle.

[0083] When the second gear set 450 is working, it can drive three reciprocating lead screws 441 to rotate. When the reciprocating lead screws 441 rotate, they can drive the actuating frame 443 and the impact rod 448 to move through the cooperation of the parts. When the actuating frame 443 and the impact rod 448 move, they can evenly distribute the falling stones on the rotating cylinder 423 and the holding plate 426.

[0084] like Figures 1-6 , Figure 8As shown, the positioning component includes a first positioning block 4610 and a second positioning block 4611 for positioning the first blocking plate 413 and the second blocking plate 416, and a first push plate 463 and a second push plate 464 for moving the first positioning block 4610 and the second positioning block 4611.

[0085] The bottom of the first baffle plate 413 and the second baffle plate 416 are respectively movably installed with a first positioning block 4610 and a second positioning block 4611, and the surface of the crushing box 100 is provided with a first push plate 463 and a second push plate 464.

[0086] It is conceivable that after the first blocking plate 413 is rotated and closed, the second positioning block 4611 can slide to the bottom of the first blocking plate 413 for positioning by the upward pushing force of the second pushing plate 464. At the same time as the first blocking plate 413 is closed, the first positioning block 4610 at the bottom of the second blocking plate 416 can slide out of the bottom of the second blocking plate 416 by the upward pushing force of the first pushing plate 463. When the first positioning block 4610 slides out of the bottom of the second blocking plate 416, the second dispensing port 414 can be opened.

[0087] like Figures 1-6 As shown, the material distribution assembly also includes a first rotating shaft 412 for rotating the first blocking plate 413, and a second rotating shaft 415 for rotating the second blocking plate 416.

[0088] The first baffle plate 413 has a first rotating shaft 412 installed through a mounting hole inside. Both ends of the first rotating shaft 412 penetrate the inner wall of the crushing box 100 and are connected to the first gear set 430. The second baffle plate 416 has a second rotating shaft 415 installed through a mounting hole inside. Both ends of the second rotating shaft 415 penetrate the inner wall of the crushing box 100 and are connected to the first gear set 430.

[0089] It is clear that when the first gear set 430 rotates, it can drive the first rotating shaft 412 to rotate. The rotation of the first rotating shaft 412 can rotate inside the crushing box 100. When the first rotating shaft 412 rotates, it can drive the first baffle plate 413 to rotate. At the same time, the rotation of the first rotating shaft 412 can drive the second rotating shaft 415 to rotate inside the crushing box 100 through the cooperation of the first gear set 430. When the second rotating shaft 415 rotates, it can drive the second baffle plate 416 to rotate. The first rotating shaft 412 and the second rotating shaft 415 can always rotate in the same direction through the cooperation of the first gear set 430.

[0090] like Figures 1-6 , Figure 8 , Figure 9As shown, the feeding assembly also includes a feeding port 421 and a third rotating shaft 422 for mounting the rotating cylinder 423, a loading trough 424 for carrying stones, and a fourth rotating shaft 425 for rotating the holding plate 426.

[0091] The discharge rack 420 has a discharge port 421. A rotating cylinder 423 is rotatably installed inside the discharge port 421. A third rotating shaft 422 is installed through the assembly hole inside the rotating cylinder 423. Both ends of the third rotating shaft 422 penetrate the inner wall of the crushed stone box 100 and are connected to the first gear set 430.

[0092] The fourth rotating shaft 425 is installed through the assembly hole inside the holding plate 426. Both ends of the fourth rotating shaft 425 penetrate the inner wall of the crushed stone box 100 and are connected to the first gear set 430.

[0093] It should be understood that the stone material can fall into the loading trough 424 through the first feeding port 411. When the stone material inside the loading trough 424 reaches the specified weight, the loading trough 424 can drive the rotating cylinder 423 to rotate through its own trapezoidal shape. When the rotating cylinder 423 rotates, it can drive the third rotating shaft 422 to rotate inside the crushed stone box 100. When the third rotating shaft 422 rotates, it can drive the fourth rotating shaft 425 to rotate through the cooperation of the first gear set 430. When the fourth rotating shaft 425 rotates, it can drive the holding plate 426 to rotate and close. At the same time, when the fourth rotating shaft 425 rotates, it can drive the second rotating shaft 415 and the first rotating shaft 412 to rotate through the cooperation of the first gear set 430.

[0094] like Figures 1-4 , Figure 6 , Figure 8 , Figure 9 As shown, the feeding assembly also includes a rotating groove 427 for rotating assembly of the third rotating shaft 422 and the fourth rotating shaft 425, and a slot 428 and a steel ball 4211 for positioning the third rotating shaft 422 and the fourth rotating shaft 425.

[0095] The inner wall of the crushing box 100 near the third rotating shaft 422 and the fourth rotating shaft 425 is provided with a rotating groove 427. The inner wall of the rotating groove 427 is provided with a slot 428. The third rotating shaft 422 and the fourth rotating shaft 425 are equipped with steel balls 4211 that match the slot 428.

[0096] It is conceivable that the weight of the stone will compress the steel ball 4211 through the third rotating shaft 422 and the fourth rotating shaft 425. When the stone reaches the specified weight, the steel ball 4211 will disengage from the slot 428. After the steel ball 4211 disengages from the slot 428, the third rotating shaft 422 and the fourth rotating shaft 425 can continue to rotate under the weight of the stone.

[0097] like Figure 2 , Figure 4 , Figure 6 , Figure 8 and Figure 9 As shown, the feeding assembly also includes a first extrusion groove 429 for the movement of the steel ball 4211, and a first extrusion spring 4210 for applying a preload to the steel ball 4211.

[0098] The third rotating shaft 422 and the fourth rotating shaft 425 are provided with a first extrusion groove 429 on the surface near the slot 428. A steel ball 4211 is movably installed inside the first extrusion groove 429. A first extrusion spring 4210 is fixedly installed between the steel ball 4211 and the first extrusion groove 429.

[0099] Understandably, the first compression spring 4210 will exert a certain preload on the steel ball 4211. When the weight of the stone is greater than the preload, the steel ball 4211 will slide completely into the interior of the first compression groove 429 and disengage from the slot 428.

[0100] like Figures 3-7 As shown, the uniform distribution assembly also includes an internally threaded slider 442 for moving the toggle bracket 443 and the impact rod 448, and a moving groove 440 for moving the internally threaded slider 442.

[0101] The discharge rack 420 is provided with moving grooves 440 on the left and right sides and the middle of the reciprocating screw 441. The reciprocating screw 441 is rotatably installed through the moving grooves 440. The surface of the reciprocating screw 441 is threadedly connected to an internal thread slider 442. A toggle frame 443 is fixedly installed on the internal thread slider 442 on the left and right sides of the reciprocating screw 441.

[0102] It is worth noting that when the reciprocating screw 441 rotates, it can drive the internal thread slider 442 to slide in the thread. When the internal thread slider 442 slides in the thread, it can slide in the moving groove 440. When the internal thread slider 442 slides in the thread, it can drive the actuating frame 443 and the impact rod 448 to move back and forth. When the actuating frame 443 moves back and forth, it can evenly distribute the fallen stones on the holding plate 426. When the impact rod 448 moves back and forth, it can evenly distribute the fallen stones inside the loading trough 424.

[0103] like Figure 3 , Figure 4 , Figures 6-7 As shown, the uniform distribution assembly also includes a mounting block 444 and a second pressing groove 445 for assembling the impact rod 448, a rotating rod 446 for rotating the impact rod 448, and a torsion spring 447 for resetting the impact rod 448.

[0104] A mounting block 444 is fixedly installed on the side of the internal thread slider 442 on the reciprocating screw 441 in the middle. A second extrusion groove 445 is opened on the side of the mounting block 444, and a rotating rod 446 is rotatably installed through the second extrusion groove 445.

[0105] The two ends of a torsion spring 447 are fixedly installed on the surface of the rotating rod 446 and the inner wall of the second extrusion groove 445, and the end of an impact rod 448 is fixedly installed on the surface of the rotating rod 446.

[0106] It should be understood that when the stone falls from the first feed opening 411, it will collide and be squeezed by the impact rod 448. When the impact rod 448 is squeezed, it will drive the rotating rod 446 to rotate. When the rotating rod 446 rotates, it can rotate inside the second extrusion groove 445. At the same time, the rotating rod 446 will twist the torsion spring 447. When the impact rod 448 rotates, its end striking head will strike the inner wall of the loading groove 424. When the inner wall of the loading groove 424 is struck, it will generate vibration, which will reduce the gap between the stones.

[0107] like Figures 1-4 , Figure 6 , Figure 8 , Figure 10 As shown, the positioning assembly also includes a first rotating plate 460 and a second rotating plate 461 for pushing the first pushing plate 463 and the second pushing plate 464 up and down, and a first limiting frame 462 for limiting the first pushing plate 463 and the second pushing plate 464.

[0108] The outer surface of the third rotating shaft 422 is fixedly mounted with a first rotating plate 460 and a second rotating plate 461. Both the first rotating plate 460 and the second rotating plate 461 have arc-shaped notches, and the two arc-shaped notches are distributed in opposite directions.

[0109] A first limiting frame 462 is fixedly installed at the front of the crushing box 100. A first pushing plate 463 and a second pushing plate 464 are movably installed inside the first limiting frame 462. Both the upper and lower ends of the first pushing plate 463 and the second pushing plate 464 are provided with arc-shaped surfaces.

[0110] It is conceivable that when the third rotating shaft 422 rotates, it can drive the first rotating plate 460 and the second rotating plate 461 to rotate simultaneously. When the first rotating plate 460 rotates, its protrusion will push the end of the first push plate 463 upward. At the same time, the second rotating plate 461 rotates simultaneously. When the second rotating plate 461 rotates, it will cause the arc-shaped notch to slide against the end of the second push plate 464. When the second rotating plate 461 rotates 180°, it will cause its protrusion to squeeze the end of the second push plate 464.

[0111] like Figures 1-6 , Figure 8 , Figure 10 As shown, the positioning assembly further includes a slide groove 4612 for the movement of the first positioning block 4610 and the second positioning block 4611, and a first push rod 466 and a second push rod 467 for pushing the first positioning block 4610 and the second positioning block 4611 to move.

[0112] The inner walls of the crushing box 100 near the first positioning block 4610 and the second positioning block 4611 are both provided with sliding grooves 4612. The end of the first positioning block 4610 is fixedly installed with a first push rod 466, and the end of the second positioning block 4611 is fixedly installed with a second push rod 467.

[0113] When the end of the first push plate 463 is squeezed, it will cause the top arc to squeeze the end of the first push rod 466. When the end of the first push rod 466 is squeezed, it can drive the first positioning block 4610 at the other end to slide in the slide groove 4612. The sliding of the first positioning block 4610 will move out of the bottom of the second blocking plate 416. When the end of the second push plate 464 is squeezed, it will move upward and push the end of the second push rod 467 through the top arc. When the end of the second push rod 467 is pushed, the other end will drive the second positioning block 4611 to slide in the slide groove 4612. When the second positioning block 4611 slides, it will move to the bottom of the first blocking plate 413 for positioning, thereby preventing the first blocking plate 413 from opening due to stone impact.

[0114] like Figures 1-6 , Figure 8 , Figure 10 As shown, the positioning assembly also includes a second limiting frame 465 for the movement of the first push rod 466 and the second push rod 467, and a second compression spring 468 and a positioning plate 469 for the reset of the first push rod 466 and the second push rod 467;

[0115] The surfaces of the first push rod 466 and the second push rod 467 are each fitted with a second limiting frame 465. The second limiting frame 465 is fixedly installed at the front of the crushed stone box 100. The ends of the first push rod 466 and the second push rod 467 away from the first positioning block 4610 and the second positioning block 4611 are each fixedly installed with one end of a second compression spring 468.

[0116] The other end of the second compression spring 468 is fixedly installed with a positioning plate 469, and the side of the positioning plate 469 is fixedly installed at the front of the crushing box 100.

[0117] When the first push plate 463 and the second push plate 464 move downwards out of the ends of the first push rod 466 and the second push rod 467, the other ends of the first push rod 466 and the second push rod 467 can be reset by the elastic force of the second compression spring 468. When the first push rod 466 is reset, it will drive the first positioning block 4610 to move to the bottom of the first blocking plate 413 for positioning. When the first push rod 466 is reset, it will drive the second positioning block 4611 to move out of the bottom of the second blocking plate 416. The second blocking plate 416 can be rotated and opened by the cooperation of the first gear set 430.

[0118] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
