Description

Technical Field

[0002] In the process of road and bridge construction, foundation pit engineering is an important link, which plays a key role in the progress and quality of the project. Foundation pit engineering mainly includes foundation pit support construction and earth excavation. During the foundation pit excavation process, a large amount of impurities mixed with stones and soil will be dug out. During construction, a large number of stones are also needed. Therefore, the excavated stones can be reused. However, the excavated stones are uneven in size, so a stone crushing device is needed to crush the excavated stones into suitable sizes.

[0003] When the stone crushing device is crushing stones, the different sizes of stones will cause different degrees of wear on the crushing roller of the crushing device. Large stones will cause greater wear on the crushing roller. When the crushing roller is worn over a large area, uneven crushing often occurs. Unevenly crushed stones will affect the construction quality of roads and bridges. Therefore, most people directly replace the crushing roller after the crushing roller is worn over a large area. However, the replacement of the crushing roller is more complicated and the economic cost is higher. Moreover, most crushing devices can only perform coarse adjustments when adjusting the crushing size. For some projects with higher requirements, it is impossible to make precise adjustments to the stone crushing, making the stone crushing more delicate, and the crushing limitations are greater.

After the operator adjusts the distance between the two crushing rollers according to the degree of stone crushing, the amount of material discharged between the two rotating plates will also be adjusted accordingly, which can prevent stones from accumulating above the crushing rollers and affecting the crushing efficiency of the crushing rollers. When the crushing block has been worn over a large area and the stone begins to be broken unevenly, the fourth motor rotates to drive the threaded rod to rotate, the connecting pipe slides to drive the second connecting rod to rotate, the arc plate squeezes the second fixed block, the crushing block is lifted up, and the length of the crushing block becomes longer after being lifted up, so that the stone can continue to be crushed. When the stone needs to be crushed more finely, the distance between the crushing block and the corresponding crushing roller is reduced through precise adjustment through the lifting of the arc plate, thereby increasing the adjustability of stone crushing and making it more adaptable.

[0037] On the outer wall of the connecting tube 433, there are axially distributed third fixing blocks 47. On the two opposite side walls of the third fixing blocks 47, there are rotatable second connecting rods 471. On the top of the third fixing blocks 47, there are grooves. Inside the grooves, there are movable fourth fixing blocks 472. On the top of the fourth fixing blocks 472, there are fixedly connected fifth fixing blocks 473. On the top of the fifth fixing blocks 473, there are fixedly connected arc-shaped plates 474. The other ends of the second connecting rods 471 are rotatably connected to the side walls of the fifth fixing blocks 473. The bottom of the second fixing block 451 abuts against the top of the arc-shaped plate 474. The number of the arc-shaped plates 474 is less than the number of the second fixing blocks 451.

[0038] When the limiting block 46 is not inserted, the sliding of the connecting tube 433 drives the second connecting rod 471 to rotate, and the arc-shaped plate 474 squeezes the second fixing block 451, and the crushing block 45 is lifted. When the crushing block 45 is worn大面积磨损时, the arc-shaped plate 474 can lift the crushing block 45 so that the crushing block 45 can still crush stones normally. When the stones need to be broken less, through the顶升 of the arc-shaped plate 474, the distance between the crushing block 45 and the opposite crushing roller 44 becomes smaller, and the crushing degree of the stones can also be adjusted through the fine adjustment of the arc-shaped plate 474.

[0039] An axially distributed first mounting block 445 is fixedly provided at the port of the crushing roller 44 away from the third motor 43, a fixedly connected clamping ring 435 is sleeved on the outer wall of the threaded rod 432 close to the first mounting block 445, an axially distributed clamping column 436 is fixedly provided on the outer wall of the clamping ring 435, a removable fifth support plate 437 is provided on the top of the clamping column 436, and the fifth support plate 437 is arc-shaped.

[0040] A second mounting block 438 is fixedly connected at the center of the arc-shaped side wall of the fifth support plate 437, a slot engaged with the clamping column 436 is provided at the bottom of the fifth support plate 437, the first mounting block 445 is aligned with the second mounting block 438 and a bolt is inserted therein, the fifth support plates 437 abut against each other, a sliding column 48 is fixedly connected on the side wall of the reducer 419 away from the crushing roller 44, the sliding column 48 is slidably connected to the through groove 16, and the outer wall of the rotating tube 431 close to the third motor 43 is slidably connected to the through groove 16.

[0041] Working principle: When in use, the hydraulic rod 41 is started, and the telescopic rod of the hydraulic rod 41 is stretched to shorten the distance between the two rotating frames 412, and the distance between the two crushing rollers 44 is also shortened. The inclination angle of the lower end of the rotating plate 33 changes with the distance between the two crushing rollers 44. The smaller the size of the stone crushing, the smaller the distance between the two rotating plates 33, and the less material is discharged. After the operator adjusts the distance between the two crushing rollers 44 according to the degree of stone crushing, the amount of material discharged between the two rotating plates 33 is also adjusted accordingly, which can prevent stones from accumulating above the crushing rollers 44 and affecting the crushing efficiency of the crushing rollers 44. Then, the stones excavated during the road and bridge construction are placed in the feeder 11, and the first motor 241 is started at the same time. The stones fall into the discharge barrel 14 from the discharge port 5 of the feeder 11. The first motor 241 rotates to drive the first cam 244 and the first bevel gear 245 to rotate synchronously. The first cam 244 rotates to drive the second bracket 231 to slide up and down, and the extrusion block 235 also moves up and down to prevent the bottom of the discharge barrel 14 from being blocked by stones. The first bevel gear 245 rotates to drive the second bevel gear 252 and the second gear 253 to rotate synchronously. The first gear 223 rotates to drive the bottom cover 22 to rotate, and the stirring column 221 also rotates accordingly, which can break up the fallen stones and reduce the probability of stones blocking the discharge barrel 14. The first electric cylinder 323, the second motor 311 and the third motor 43 are started. The first electric cylinder 323 is stretched to drive the rotating plate 33 to rotate. The telescopic rods of the first electric cylinder 323 symmetrically distributed at the bottom of the rotating plate 33 are stretched alternately. The first rotating ball 322 and the second rotating ball 331 cooperate with each other. The two ends of the rotating plate 33 rotate at multiple angles. The stones can evenly fall along the rotating plate 33 to the top of the crushing roller 44 for crushing, thereby reducing the uneven wear of the crushing roller 44. The second motor 311 rotates to drive the synchronous belt 313, and the symmetrically distributed second cam 341 rotates synchronously, driving the first connecting rod 342 to rotate. The first connecting rod 342 rotates to drive the knocking rod 35 to move back and forth. The knocking rod 35 knocks the bottom of the rotating plate 33 to assist in stone unloading. The third motor 43 rotates to drive the crushing roller 44 to rotate, and the crushing block 45 rotates to crush the stone. After the crushing block 45 crushes the stone, it passes through the brush 416. The brush 416 can clean up the debris contaminated by the crushing block 45. Then the crushing block 45 drives the thin sheet 422 to rotate upward, and the thin sheet 422 hits the contact sensor 424. The contact sensor 424 sends a signal, and the crushed stone falls from the unloading port 6. When most of the contact sensor 424 signals are missing, it means that the crushing block 45 has been worn over a large area, and the stones begin to be broken unevenly. The unevenly broken stones will affect the construction quality of the road and bridge. At this time, the bolts fixing the first mounting block 445 and the second mounting block 438 are removed, the fifth support plate 437 is removed, the limit block 46 is withdrawn, and the fourth motor 418 is started. The fourth motor 418 rotates to drive the threaded rod 432 to rotate, the threaded slider 434 is threadedly matched with the threaded rod 432, the threaded rod 432 rotates to drive the connecting pipe 433 to slide, the connecting pipe 433 slides to drive the second connecting rod 471 to rotate, the arc plate 474 squeezes the second fixed block 451, and the crushing block 45 is lifted up; After being lifted up, the length of the crushing block 45 becomes longer and can continue to crush stones. When the stones need to be crushed more finely, through the lifting of the arc plate 474, the distance between the crushing block 45 and the corresponding crushing roller 44 is reduced through precise adjustment, thereby increasing the adjustability of stone crushing and making it more adaptable. After the crushing block 45 is adjusted, the limit block 46 is reinserted to fix the position of the crushing block 45, and the fifth support plate 437 is fixed to the crushing roller 44 by bolts. When the crushing block 45 can no longer be used, only the crushing block 45 needs to be replaced, which can reduce the replacement cost.
