Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a crusher for construction engineering. Background Technique

[0002] Construction engineering plays an important role in social and economic development. At the same time, it also requires careful planning and management to minimize negative impacts and ensure sustainability and effective utilization of resources. In the construction of dams and barrages, it is usually necessary to process large pieces of rock during the construction of the dam foundation. Crushers are used to break these hard rocks into appropriate sizes for subsequent engineering construction.

[0003] After retrieval, some crushers install a screen under the crushing roller to further screen and classify the crushed particles. Since the contact time between the crushing roller and the rock is very short and the rock is relatively hard, the size and shape of the crushed rock particles may vary. Some may get stuck on the screen and cause blockage, reducing the discharging effect and working efficiency. Secondly, the dust is relatively large when the rock is being crushed, and some broken particles may be thrown out by the centrifugal force of the rotating crushing roller, endangering the construction workers and reducing the safety of the construction workers.

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figure 1 - Figure 6, the utility model provides a crusher for construction engineering, which includes a crushing chamber 4. A filter plate 9 is slidably connected through the front surface of the crushing chamber 4. A collecting shell 1 is fixedly connected to the bottom end of the left surface of the crushing chamber 4. A support seat 6 is fixedly connected to the right surface of the crushing chamber 4. A motor is fixedly connected to the upper surface of the support seat 6. The motor is a prior art and can be realized by those skilled in the art. Since it is a prior art, it will not be described in detail in this case. A circular plate 11 is fixedly connected to the left surface of the motor. The top end of the left surface of the circular plate 11 is fixedly connected to a cylinder 10. When the circular plate 11 rotates, the cylinder 10 will rotate at the eccentric position of the circular plate 11. At the same time, the left end of the cylinder 10 will slide on the inner wall of the irregular gear 12. By combining the different movement modes at both ends of the cylinder 10, the irregular gear 12 can make a reciprocating swinging movement with the center of the fixed shaft 13 as the origin, so that the filter plate 9 can shake back and forth to screen the crushed stones and avoid clogging of the filter plate 9. A fixed shaft 13 is fixedly connected to the right surface of the crushing chamber 4. An irregular gear 12 is rotatably connected to the outer wall of the fixed shaft 13. A through groove 1 is opened on the right surface of the crushing chamber 4, and a rack 7 is slidably connected to the inner wall of the through groove 1.

[0028] Further, a first rectangular shell 2 is fixedly connected to the left end of the upper surface of the crushing bin 4, and a second rectangular shell 5 is fixedly connected to the right end of the upper surface of the crushing bin 4. A rotating shaft 8 is rotatably connected through the front surface of the second rectangular shell 5. An concave block 18 is fixedly connected to the upper surface of the rotating shaft 8. A limiting plate 17 is hinged to the inner wall of the concave block 18. When the limiting plate 17 is pulled upward, the limiting plate 17 will rotate around its hinge point with the concave block 18, causing the rear end of the limiting plate 17 to disengage from the inner wall of the second through groove, thus releasing the limitation on the rotating shaft 8. A convex limiting block 19 is rotatably connected to the outer wall of the rotating shaft 8. Multiple groups of second through grooves are provided on the front surface of the convex limiting block 19. The multiple groups of second through grooves are provided to limit different opening degrees of the cover plate 3 by the limiting plate 17. The rear end of the limiting plate 17 slides on the inner wall of the second through groove. A third through groove is provided on the left surface of the second rectangular shell 5. A connecting block 14 is slidably connected to the inner wall of the third through groove. A cover plate 3 is fixedly connected to the left surface of the connecting block 14. A ring 15 is fixedly connected to the right surface of the connecting block 14. The ring 15 is slidably connected to the inner wall of the second rectangular shell 5. A slide bar 20 is fixedly connected to the inner wall of the ring 15. When the rotating shaft 8 is rotated, the slide bar 20 will move backward along the spiral groove, and the cover plate 3 will also open accordingly. When the limiting plate 17 does not limit the rotating shaft 8, the construction worker only needs to release the hand, and the spring 16 will push the ring 15 forward through its own reaction force to close the cover plate 3. At this time, the slide bar 20 will also slide on the inner wall of the spiral groove to reverse the rotating shaft 8. A spiral groove is provided on the outer wall of the rotating shaft 8. The right surface of the slide bar 20 is slidably connected to the inner wall of the spiral groove. A spring 16 is sleeved on the outer wall of the rotating shaft 8. The spring 16 always pushes the ring 15 forward through its own elasticity, ensuring that when the limiting plate 17 releases the limitation on the rotating shaft 8, the ring 15 will drive the cover plate 3 to automatically close through the reaction force of the spring 16. A slider 21 is fixedly connected to the left surface of the cover plate 3. A rectangular groove is provided on the right surface of the first rectangular shell 2.

[0029] Further, a rack 7 is fixedly connected to the right surface of the filter plate 9. An irregular gear 12 meshes with the right end of the upper surface of the rack 7. The left end of the outer wall of the cylinder 10 is slidably connected to the inner wall of the irregular gear 12. A convex limiting block 19 is fixedly connected to the front surface of the second rectangular shell 5. Pushing the limiting plate 17 into the inner wall of the second through groove provided on the front surface of the convex limiting block 19 can limit the rotating shaft 8, ensuring quick and stable limitation. The slider 21 is slidably connected to the inner wall of the rectangular groove. One end of the spring 16 is fixedly connected to the inner wall of the second rectangular shell 5, and the other end of the spring 16 is fixedly connected to the rear surface of the ring 15.

[0030] In the present utility model, during use, by pushing the limit plate 17 upwards, the limit plate 17 will rotate with the center of the hinge joint between it and the concave block 18 as the origin until the rear end of the limit plate 17 slides out from the inner wall of the second through groove. At this time, the rotating shaft 8 can be rotated. At this time, the sliding rod 20 will slide backwards along the arc of the spiral groove. The sliding rod 20 will drive the ring 15 to slide backwards on the inner wall of the second rectangular shell 5 while squeezing the spring 16. At this time, the cover plate 3 will move backwards following the ring 15 through the connecting block 14, and the slider 21 will also slide backwards on the inner wall of the rectangular groove until the cover plate 3 is completely opened. At this time, rotate the limit plate 17 back so that its rear end slides into the inner wall of the second through groove, so as to limit the cover plate 3 and keep the cover plate 3 open for a long time, which is convenient for discharging materials. When the discharging is completed, only need to release the limit of the rotating shaft 8 by the limit plate 17 and then let go. At this time, the spring 16 will drive the ring 15 to move forward through its own elasticity. The ring 15 will drive the sliding rod 20 to slide forward on the inner wall of the spiral groove to reverse the rotating shaft 8. In this way, the cover plate 3 will move forward following the ring 15 and close to prevent the particles from flying out and hurting the construction workers.

[0031] When crushing, the motor can be started. The motor drives the circular plate 11 to rotate, and the cylinder 10 will rotate accordingly at the eccentric position of the circular plate 11. At the same time, the left end of the cylinder 10 will slide back and forth on the inner wall of the irregular gear 12. In this way, the irregular gear 12 will swing back and forth with the center of the fixed shaft 13 as the center. At this time, the rack 7 will make a reciprocating motion back and forth following the irregular gear 12, and the filter plate 9 will make a reciprocating motion back and forth following the rack 7 to screen the crushed stone particles. In this way, the risk of the irregular crushed stones blocking the filter plate 9 is greatly reduced, and the smoothness of the discharge is improved. And the too large particles will roll into the inside of the collection shell 1 along the inclination of the filter plate 9. The workers can pick and process them again on the inner wall of the collection shell 1, improving the utilization rate.

[0032] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
