[0001] This utility model relates to the field of crusher technology, specifically to a crusher for engineering construction with multiple crushing structures. Background Technology

[0002] Crusher used in engineering construction is mainly used to process and crush various materials, such as rocks, concrete, and bricks, to facilitate subsequent transportation and reuse. Different types of crushers can be selected according to different construction needs and material types.

[0003] After the existing crusher finishes crushing the material, in order not to affect the normal collection of the material, the material will fall into the collection box at the bottom. When there is a large piece of material, it needs to be poured back into the crusher for further crushing, which is very cumbersome and does not have the function of automatically crushing large particles. Utility Model Content

[0004] The purpose of this invention is to provide a crusher for engineering construction with a multi-crushing structure, so as to solve the problem mentioned in the background art that the crushers currently in use do not have the ability to perform multi-crushing of materials.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a crusher for engineering construction with a multi-crushing structure, comprising: a shell and a discharge port, wherein a feed port is provided at the top of the shell, a movable frame is installed inside the shell, a drive motor is installed inside the movable frame, the output end of the drive motor is connected to a crushing mechanism through a coupling, and the discharge port is located at the bottom of the shell.

[0006] The interior of the outer casing is equipped with a screen, the bottom of which is fitted with a guide rail. A movable rod is mounted on the bottom of the guide rail. A fixed block is sleeved on the outer side of one set of the movable rods. A movable spring connects the outer side of the movable rods and the fixed block. A protrusion is provided on the bottom of the movable rods. A turntable is connected to one side of the protrusion. A servo motor is connected to one side of the turntable via an output shaft. A return spring connects the bottom of another set of the movable rods to a groove in the outer casing. A chain conveyor is installed on one side of the screen, and a receiving plate is installed on one side of the chain conveyor. A belt conveyor is installed on the top of the outer casing, and a drive belt connects the drive rollers of the chain conveyor and the belt conveyor.

[0007] Preferably, the drive roller at the bottom of the chain conveyor is connected to the output shaft of the motor via a synchronous belt.

[0008] Preferably, the chain conveyor is mounted on one side of the housing via a protective cover.

[0009] Preferably, sliders are installed on both sides of the movable frame, a lead screw is connected through the middle of one set of sliders, a drive motor that penetrates the outer shell is connected to one side of the lead screw, a smooth rod is connected through the middle of one side of the other set of sliders, and a sliding frame is connected to the end of the crushing mechanism away from the drive motor.

[0010] Preferably, both sides of the sliding frame are also connected to the lead screw and guide rod via sliders.

[0011] Preferably, the crushing mechanism is connected to the sliding frame via a bearing, and two sets of crushing blocks with different spacings are provided on the outer side of the crushing mechanism.

[0012] Preferably, the light rod is installed inside the housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the engineering construction crusher with a multi-crushing structure is in use, the servo motor can be started, which will drive the turntable to rotate. When the turntable rotates, it will work with the protrusion, movable spring, and return spring to drive the movable rod to move up and down, thereby causing the screen to vibrate continuously. At this time, the material on the screen will be shaken off onto the receiving plate on one side of the chain conveyor, and then the receiving plate will transport the material to the belt conveyor. Finally, the belt conveyor will transport the material back to the crushing mechanism for re-crushing, thus achieving a multi-crushing effect and making the crushing effect of the material better. This is the characteristic of the engineering construction crusher with a multi-crushing structure.

[0014] 1. This construction crusher with a multi-crushing structure can screen materials through a screen during use. Larger materials after screening will roll onto a receiving plate on one side of the chain conveyor. The receiving plate will then transport the materials to a belt conveyor, which will then transport the materials back into the interior of the outer shell. This process can achieve multiple screening of materials until the desired crushing effect is achieved.

[0015] 2. This construction crusher with a multi-crushing structure can be used to adjust the crushing effect of materials by starting the drive motor according to the crushing requirements of the materials. The drive motor drives the crushing mechanism through the lead screw and slider. By adjusting the crushed blocks with different spacing on the outside of the crushing mechanism to the bottom of the feed inlet, the crushing effect of the materials can be adjusted.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a crusher for engineering construction with a multi-crushing structure, including: a shell 1 and a discharge port 24. The top of the shell 1 is provided with a feed port 2. A movable frame 3 is installed inside the shell 1. A drive motor 4 is installed inside the movable frame 3. The output end of the drive motor 4 is connected to a crushing mechanism 5 through a coupling. The discharge port 24 is located at the bottom of the shell 1.

[0023] The interior of the outer casing 1 is equipped with a screen 6. A guide rail 7 is installed at the bottom of the screen 6. A movable rod 8 is installed at the bottom of the guide rail 7. A fixed block 9 is sleeved on the outer side of one set of movable rods 8. A movable spring 10 is connected between the outer side of the movable rod 8 and the fixed block 9. A protrusion 11 is provided at the bottom of the movable rod 8. A turntable 12 is connected to one side of the protrusion 11. A servo motor 13 is connected to one side of the turntable 12 through an output shaft. A return spring 14 is connected between the bottom of another set of movable rods 8 and the groove of the outer casing 1. A chain conveyor 15 is provided on one side of the screen 6. A receiving plate 16 is installed on one side of the chain conveyor 15. A belt conveyor 17 is installed on the top of the outer casing 1. A drive belt 18 is connected between the drive roller of the chain conveyor 15 and the drive roller of the belt conveyor 17. The drive roller at the bottom of the chain conveyor 15 is connected to the output shaft of the motor through a synchronous belt. The chain conveyor 15 is installed on one side of the outer casing 1 through a protective cover. The chain conveyor 15 is installed vertically on one side of the outer casing 1.

[0024] In practical implementation, when the construction crusher with multiple crushing structures needs to crush the construction materials in multiple ways, the servo motor 13 can be started. The servo motor 13 will drive the turntable 12 to rotate, so that the turntable 12 drives the protrusion 11 on one side to move in a circular motion. The top of the protrusion 11 is provided with a movable rod 8, and the top of the movable rod 8 is connected to the guide rail 7 at the bottom of the screen 6 through a ball bearing. When the protrusion 11 moves upward and rotates, it will squeeze the movable rod 8, causing the movable rod 8 to move upward. The upward movement of the movable rod 8 will push the screen 6 to move upward, and at the same time, the movable spring 10 on the outside of the movable rod 8 will be in a stretched state. At the same time, the upward movement of the screen 6 will also cause another set of movable rods 8 to move upward, and the return spring 14 at the bottom of the other set of movable rods 8 will be in a stretched state.

[0025] When the protrusion 11 rotates downward, the protrusion 11 no longer squeezes the movable rod 8. Under the reset action of the movable spring 10 and the return spring 14, the screen 6 will move downward. By repeating the above steps, the screen 6 will vibrate, and some larger particles of material will roll off the screen 6 onto the chain conveyor 15.

[0026] Since the chain conveyor 15 is vertically installed on one side of the outer casing 1, and a receiving plate 16 is installed on one side of the chain conveyor 15, the chain conveyor 15 drives the output shaft to rotate via a motor at the bottom. The output shaft drives the sprocket to rotate via a pulley and a synchronous belt. When the sprocket rotates, it drives the outer chain to rotate. Since the receiving plate 16 is installed on one side of the chain, when the chain conveyor 15 is working, it will drive the receiving plate 16 to move. At this time, the material rolling off the screen 6 will fall onto the receiving plate 16, and then the chain conveyor 15 and the receiving plate 16 will drive the material to move upward. When the receiving plate 16 moves upward... When the chain conveyor 15 moves to the top, the receiving plate 16 will rotate, and the material on the receiving plate 16 will fall onto the belt conveyor 17 at the bottom of the outer shell 1. A drive belt 18 is connected between the drive roller of the chain conveyor 15 and the drive roller of the belt conveyor 17. Therefore, under the action of the drive belt 18, the belt conveyor 17 will rotate. When the material on the belt conveyor 17 is conveyed to the feed inlet 2, it will fall off the belt conveyor 17 and re-enter the outer shell 1 for crushing. Therefore, it has the function of multiple crushing of multiple materials, making the crushing effect of the material better.

[0027] See Figure 1 , Figure 3 and Figure 4As can be seen, during use, the material can be screened through the screen 6, and then larger materials will be conveyed upward through the chain conveyor 15 and then conveyed to the belt conveyor 17, and then conveyed back into the interior of the outer shell 1 by the belt conveyor 17. Thus, the material can be screened multiple times, making the screening effect of the material better.

[0028] Both sides of the movable frame 3 are equipped with sliders 19. A lead screw 20 is connected through the middle of one set of sliders 19. A drive motor 21 that passes through the outer shell 1 is connected to one side of the lead screw 20. A smooth rod 22 is connected through the middle of one side of the other set of sliders 19. The end of the crushing mechanism 5 away from the drive motor 4 is connected to a sliding frame 23. Both sides of the sliding frame 23 are also connected to the lead screw 20 and the smooth rod 22 through sliders 19. The crushing mechanism 5 is connected to the sliding frame 23 through bearings. Two sets of crushing blocks with different spacings are set on the outside of the crushing mechanism 5. The smooth rod 22 is installed inside the outer shell 1. The lead screw 20 and the slider 19 are connected by threads.

[0029] In practical implementation, when the crushing effect of the material needs to be adjusted, the engineering construction crusher with multiple crushing structures only needs to start the drive motor 21. The drive motor 21 will drive the lead screw 20 to rotate through the coupling. The lead screw 20 and the slider 19 are connected by threads. The slider 19 is connected to both sides of the sliding frame 23 and the movable frame 3 respectively. Another set of sliders 19 is slidably connected to the outside of the smooth rod 22. Under the guidance of the smooth rod 22 and the slider 19, the lead screw 20 will drive the slider 19 to slide when it rotates. The sliding of the slider 19 will drive the entire crushing mechanism 5 to move through the sliding frame 23 and the movable frame 3. By adjusting the crushed blocks with different spacing on the outside of the crushing mechanism 5 to the bottom of the feed inlet 2, the crushing effect of the material can be adjusted, thereby meeting the different needs of users.

[0030] See Figure 2 As can be seen, when in use, the drive motor 21 can be started according to the usage requirements. The drive motor 21 will drive the entire crushing mechanism 5 to rotate through the lead screw 20 and the slider 19. After aligning the crushed blocks with different spacings with the feed inlet 2, different crushing effects can be achieved on the material.

[0031] In summary: When using this construction crusher with a multi-crushing structure, the drive motor 4 in the movable frame 3 can be started. The drive motor 4 will drive the crushing mechanism 5 to rotate. The crushing mechanism 5 mainly consists of two sets of crushing rollers connected together by gears. Crushing blocks are set on the outer side of the two sets of crushing rollers. At this time, the material is poured into the outer shell 1 through the feed port 2, and then the material can be crushed by the rotation of the crushing rollers. After being crushed by the crushing mechanism 5, the material falls onto the screen 6. After being screened by the screen 6, the crushing work of the material is completed. This is the usage feature of the construction crusher with a multi-crushing structure. The contents not described in detail in this description belong to the prior art known to those skilled in the art.
