Description

Technical Field

[0001] The invention relates to the technical field of highway construction, in particular to a high-efficiency multi-stage stone crushing equipment used for highway construction. Background Art

[0002] Highway construction refers to the general term for 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 grasped, so it is necessary to crush the stones through high-efficiency multi-stage stone crushing equipment.

[0003] The existing announcement number CN114950687B discloses a high-efficiency multi-stage stone crushing equipment for highway construction, including a stone crushing device, which is installed in a box body, a triangular block is fixedly connected to the inside of the box body, and an upper crushing roller is rotatably connected to the inside of the box body. The stone crushing device also includes: a V-shaped plate, an inclined block, a scraper, a baffle, and a lower crushing roller. The high-efficiency multi-stage stone crushing equipment for highway construction, the stones after preliminary crushing will fall on the triangular block and press the push plate to rotate, the push plate will rotate downward, at this time the pull rope is no longer straight, and the rotating plate will automatically rotate and open through the torsion spring, and the stones that slide down will pass through the opened rotating plate and fall on the V-shaped plate, thereby achieving the stone The intermittent falling of the stone can prevent too many stones from falling at one time, and then too many stones will fall on the lower crushing roller at one time, and then all the stones cannot be knocked away, thereby improving the effect of secondary crushing. However, when the stone falls on the push plate, the push plate can open the rotating plate at the same time through the pull rope. The simultaneous opening of the push plate and the rotating plate will cause the stone to fall on the V-shaped plate at the same time, and it is impossible to achieve indirect falling of the stone on the crushing roller. The small discharge port of the V-shaped plate will cause the stone to accumulate in the middle position of the crushing roller, making the stone crushing effect lower, and after the push plate is opened, the stone will first pass through the push plate and fall onto the V-shaped plate, which will lead to too low a utilization rate of the rotating plate, inconvenient indirect unloading, and poor stone crushing effect.

[0023] See also Figure 1-Figure 3The present invention provides an embodiment: a high-efficiency multi-stage stone crushing equipment for highway construction, comprising a stone crushing box 100, wherein a feed port 200 is installed on the top of the stone crushing box 100, wherein a primary stone crushing mechanism 300 for primary crushing of stone is fixedly installed inside the stone crushing box 100 near the feed port 200, wherein a diverter mechanism 400 for batch crushing of stone is fixedly installed at the inner middle position of the stone crushing box 100, wherein the diverter mechanism 400 comprises a material dividing component and a material discharging component for indirect material feeding of stone, and a uniform distribution component for uniform material discharging, wherein a secondary stone crushing mechanism 500 for secondary crushing of stone is installed near the bottom of the diverter mechanism 400 of the stone crushing box 100, wherein a material discharging port 600 is provided near the bottom of the secondary stone crushing mechanism 500 of the stone crushing box 100; It should be understood that the stone to be crushed is poured into the interior of the crushing box 100 through the feed port 200. After entering the crushing box 100, the stone will fall onto the primary crushing mechanism 300. The primary crushing mechanism 300 performs primary crushing on the stone through the cooperation of the driving member and the crushing barrel. After the primary crushing, the stone will fall onto the dividing component of the diverter mechanism 400. The dividing component can indirectly transport the crushed stone to the unloading component through the cooperation of parts. When the stone falls on the unloading component, the stone can be evenly distributed on the unloading component through the work of the even distribution component. When the stone reaches the specified weight, the stone can be evenly transported to the secondary crushing mechanism 500 through the unloading component for secondary crushing. After the secondary crushing, the stone can be discharged through the discharge port 600.

[0024] like Figure 1 , Figure 4-Figure 5 As shown, the flow dividing mechanism 400 further includes a first gear set 430 for driving the material dividing component and the material discharging component to work, the first gear set 430 includes multiple sets of gears and toothed belts and other components, and a second gear set 450 for driving the uniform distribution component to rotate, the second gear set 450 includes a driving member, multiple sets of gears and toothed belts and other components, and a positioning component for locking the material dividing component; It can be imagined that the material dividing component and the material unloading component can perform indirect unloading through the cooperation of the first gear group 430, the uniform distribution component can move the stone through the cooperation of the second gear group 450, and the positioning component of the material dividing component can indirectly lock its components during indirect unloading.

[0025] like Figure 1-Figure 6 As shown, the material dividing assembly includes a material dividing frame 410 for dividing the stone material to two sides, a first material dividing opening 411 and a second material dividing opening 414 for discharging the material, and a first blocking plate 413 and a second blocking plate 416 for blocking the material; A material distribution frame 410 is fixedly installed inside the crushed stone box 100, and a first material distribution opening 411 and a second material distribution opening 414 are opened on both sides of the material distribution frame 410, and a first blocking plate 413 and a second blocking plate 416 are rotatably installed inside the first material distribution opening 411 and the second material distribution opening 414 respectively; It is worth noting that the first blocking plate 413 and the second blocking plate 416 can be opened and closed indirectly through the cooperation of the first gear set 430. When the first blocking plate 413 opens the first dispensing port 411, the second blocking plate 416 closes the second dispensing port 414, and vice versa.

[0026] like Figure 1-Figure 6 As shown, the unloading assembly includes a discharging rack 420 for unloading, and a rotating cylinder 423 and a containing plate 426 for containing stones; A discharging rack 420 is fixedly installed at the center of the bottom of the discharging rack 410, and a rotating cylinder 423 is rotated inside the discharging rack 420. A holding plate 426 is rotatably installed inside the crushed stone box 100 near the left and right sides of the discharging rack 410. It should be understood that after the first blocking plate 413 opens the first material distribution port 411, the stone will fall onto the rotating cylinder 423. When the stone on the rotating cylinder 423 reaches the specified weight, the rotating cylinder 423 will rotate to pour the stone into the secondary stone crushing mechanism 500. While the rotating cylinder 423 rotates, it can drive the holding plate 426 to rotate and close through the cooperation of the first gear set 430. While the holding plate 426 rotates and closes, it can drive the second blocking plate 416 to rotate through the cooperation of the first gear set 430 to open the second material distribution port 414. While the second material distribution port 414 is opened, the second blocking plate 416 rotates and can drive the first blocking plate 413 to rotate through the cooperation of the first gear set 430 to close the first material distribution port 411. After the second material distribution port 414 is opened, the stone will fall onto the holding plate 426. When the stone on the holding plate 426 reaches the specified weight, it can be opened.

[0027] like Figure 1-Figure 7 As shown, the uniform distribution assembly includes a reciprocating screw rod 441 for movement, and a toggle frame 443 and a striking rod 448 for uniformly distributing the stones; A reciprocating screw rod 441 is rotatably mounted on the left and right sides and the middle of the discharging frame 420 through the mounting cavity. The end of the reciprocating screw rod 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 rod 441 on the left and right sides, and a striking rod 448 is movably mounted on the reciprocating screw rod 441 in the middle.

When the reciprocating screw 441 rotates, it can drive the toggle frame 443 and the impact rod 448 to move respectively through the cooperation of parts. When the toggle frame 443 and the impact rod 448 move, the fallen stones can be evenly distributed on the rotating cylinder 423 and the containing plate 426.

[0028] like Figure 1-Figure 6 , Figure 8 As shown, the positioning assembly 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 pushing plate 463 and a second pushing plate 464 for driving the first positioning block 4610 and the second positioning block 4611 to move; A first positioning block 4610 and a second positioning block 4611 are movably mounted at the bottom of the first blocking plate 413 and the second blocking plate 416, respectively. A first pushing plate 463 and a second pushing plate 464 are disposed on the surface of the gravel box 100. It can be imagined that after the first baffle plate 413 is rotated and closed, the second positioning block 4611 can slide to the bottom of the first baffle plate 413 for positioning through the driving force of the upward movement of the second push plate 464. When the first baffle plate 413 is closed, the first positioning block 4610 at the bottom of the second baffle plate 416 can slide out of the bottom of the second baffle plate 416 through the driving force of the upward movement of the first push plate 463. When the first positioning block 4610 slides out of the bottom of the second baffle plate 416, the second material distribution port 414 can be opened.

[0029] like Figure 1-Figure 6 As shown, the material distributing assembly further 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; The first blocking plate 413 is provided with a first rotating shaft 412 through a mounting hole, and both ends of the first rotating shaft 412 penetrate the inner wall of the crushed stone box 100 and are connected to the first gear set 430. The second blocking plate 416 is provided with a second rotating shaft 415 through a mounting hole, and both ends of the second rotating shaft 415 penetrate the inner wall of the crushed stone box 100 and are connected to the first gear set 430. It can be understood that when the first gear set 430 rotates, the first rotating shaft 412 can be driven to rotate. The rotation of the first rotating shaft 412 can rotate inside the gravel box 100. When the first rotating shaft 412 rotates, the first blocking plate 413 can be driven to rotate. When the first rotating shaft 412 rotates, the second rotating shaft 415 can be driven to rotate inside the gravel box 100 through the cooperation of the first gear set 430. When the second rotating shaft 415 rotates, the second blocking plate 416 can be driven 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.

[0030] like Figure 1-Figure 6 , Figure 8 , Fig. 9 As shown, the material discharge assembly further includes a material discharge port 421 and a third rotating shaft 422 for installing the rotating cylinder 423, a loading trough 424 for carrying stones, and a fourth rotating shaft 425 for rotating the holding plate 426; The discharge rack 420 is provided with a discharge port 421, a rotating cylinder 423 is rotatably installed inside the discharge port 421, a third rotating shaft 422 is installed inside the rotating cylinder 423 through an assembly hole, and both ends of the third rotating shaft 422 pass through the inner wall of the crushed stone box 100 and are connected to the first gear set 430; A fourth rotating shaft 425 is installed through the assembly hole inside the containing plate 426, and both ends of the fourth rotating shaft 425 penetrate the inner wall of the gravel box 100 and are connected to the first gear set 430; It should be understood that stones can fall into the loading trough 424 through the first material distribution port 411. When the stones in the loading trough 424 reach a 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 crushing 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 containing plate 426 to rotate and close. 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.

[0031] like Figure 1-Figure 4 , Figure 6 , Figure 8 , Fig. 9 As shown, the blanking assembly further includes a rotation groove 427 for rotationally assembling the third rotating shaft 422 and the fourth rotating shaft 425, and a clamping groove 428 and a steel ball 4211 for positioning the third rotating shaft 422 and the fourth rotating shaft 425; The inner wall of the gravel box 100 near the third rotating shaft 422 and the fourth rotating shaft 425 is provided with a rotation groove 427, the inner wall of the rotation groove 427 is provided with a clamping groove 428, and the third rotating shaft 422 and the fourth rotating shaft 425 are provided with a steel ball 4211 matching the clamping groove 428; It can be imagined that the weight of the stone will squeeze 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 be separated from the slot 428. After the steel ball 4211 is separated from the slot 428, the third rotating shaft 422 and the fourth rotating shaft 425 can continue to rotate due to the weight of the stone.

[0032] like Figure 2 , Figure 4 , Figure 6 , Figure 8 and Fig. 9 As shown, the blanking assembly further includes a first extrusion groove 429 for the movement of the steel ball 4211, and a first extrusion spring 4210 for applying a pre-tightening force to the steel ball 4211; The third rotating shaft 422 and the fourth rotating shaft 425 have a first extrusion groove 429 on their surfaces 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. It is understandable that the first extrusion spring 4210 will exert a certain pre-tightening force on the steel ball 4211 . When the weight of the stone is greater than the pre-tightening force, the steel ball 4211 will completely slide into the inside of the first extrusion groove 429 and disengage from the slot 428 .

[0033] like Figure 3-Figure 7 As shown, the uniform distribution assembly further includes an internal threaded slider 442 for moving the toggle frame 443 and the impact rod 448, and a moving groove 440 for moving the threaded slider 442; The discharging frame 420 is provided with movable grooves 440 on both sides and the middle of the reciprocating screw rod 441, and the reciprocating screw rod 441 is rotatably installed inside the movable groove 440. The surface of the reciprocating screw rod 441 is threadedly connected with a threaded slider 442, and the threaded sliders 442 on the reciprocating screw rods 441 on the left and right sides are fixedly installed with a toggle frame 443; It is worth noting that when the reciprocating screw rod 441 rotates, it can drive the threaded slider 442 to slide in a threaded manner. When the threaded slider 442 slides in a threaded manner, it can slide in the movable groove 440. When the threaded slider 442 slides in a threaded manner, it can drive the toggle frame 443 and the impact rod 448 to move forward and backward. When the toggle frame 443 moves forward and backward, the fallen stones can be evenly distributed on the containing plate 426. When the impact rod 448 moves forward and backward, the fallen stones can be evenly distributed inside the loading trough 424.

[0034] like Figure 3 , Figure 4 , Figure 6-Figure 7 As shown, the uniform distribution assembly further includes a mounting block 444 and a second extrusion 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; A mounting block 444 is fixedly mounted on the side of the threaded slider 442 on the middle reciprocating screw rod 441, and a second extrusion groove 445 is opened on the side of the mounting block 444. A rotating rod 446 is rotatably mounted through the second extrusion groove 445; The two ends of a torsion spring 447 are fixedly mounted on the surface of the rotating rod 446 and the inner wall of the second extrusion groove 445 , and the end of a striking rod 448 is fixedly mounted on the surface of the rotating rod 446 ; It should be understood that when the stone falls from the first material distribution port 411, it will collide and squeeze with 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. When the rotating rod 446 rotates, it will twist the torsion spring 447. When the impact rod 448 rotates, the striking head at its end will knock on the inner wall of the loading trough 424. When the inner wall of the loading trough 424 is knocked, it will vibrate to reduce the gap between the stones.

[0035] like Figure 1-Figure 4 , Figure 6 , Figure 8 , Fig.10 As shown, the positioning assembly further 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; The outer surface of the third rotating shaft 422 is fixedly mounted with a first rotating plate 460 and a second rotating plate 461. The surfaces of the first rotating plate 460 and the second rotating plate 461 are both provided with arc-shaped notches, and the two arc-shaped notches are arranged oppositely. A first limiting frame 462 is fixedly installed at the front of the gravel box 100, and a first push plate 463 and a second push plate 464 are movably installed inside the first limiting frame 462. The upper and lower ends of the first push plate 463 and the second push plate 464 are both provided with arc surfaces; It can be imagined 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 at the same time. When the second rotating plate 461 rotates, it will drive the arc-shaped notch and the end of the second push plate 464 to slide. When the second rotating plate 461 rotates 180°, it will drive its protrusion to squeeze the end of the second push plate 464.

[0036] like Figure 1-Figure 6 , Figure 8 , Fig.10 As shown, the positioning assembly further includes a slide groove 4612 for the first positioning block 4610 and the second positioning block 4611 to move, 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; The inner wall of the gravel box 100 near the first positioning block 4610 and the second positioning block 4611 is penetrated with a sliding groove 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; When the end of the first push plate 463 is squeezed, it will drive 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 through the top arc to push the end of the second push rod 467. 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 being opened by being hit by stones.

[0037] like Figure 1-Figure 6 , Figure 8 , Fig.10 As shown, the positioning assembly further includes a second limiting frame 465 for the first push rod 466 and the second push rod 467 to move, and a second extrusion spring 468 and a positioning plate 469 for resetting the first push rod 466 and the second push rod 467; The surfaces of the first push rod 466 and the second push rod 467 are sleeved with a second limit frame 465, and the second limit frame 465 is fixedly installed at the front of the gravel 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 fixedly installed with one end of the second extrusion spring 468; A positioning plate 469 is fixedly mounted on the other end of the second extrusion spring 468, and a side surface of the positioning plate 469 is fixedly mounted on the front of the gravel box 100; When the first push plate 463 and the second push plate 464 move downward 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 extrusion 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 through the cooperation of the first gear set 430.
