[0002] With the continuous development of the economy and society, the process of urbanization is accelerating, and a large amount of concrete is being used in urban construction. The number of concrete mixing plants is also increasing. However, concrete mixing plants inevitably generate a large amount of concrete waste. Direct discharge of this waste would cause environmental damage. Currently, concrete waste from concrete mixing plants is mainly reused through concrete waste recycling devices to reduce environmental pollution.

[0003] Currently, when recycling concrete, screening is usually used to separate the stones and cement in the waste concrete. After screening, although the cement can be discharged through the screen, the fixed screen is in a static state, and the accumulated concrete can easily clog the screen, resulting in a significant reduction in screening efficiency. Moreover, the stones blocked by the screen need to be removed manually by opening the machine. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-5 This utility model provides a technical solution:

[0024] A concrete waste separation device includes a collection box 1, a hopper 2 fixedly connected to the top of the collection box 1, the interiors of the collection box 1 and the hopper 2 being interconnected, a drawer 3 slidably connected to the bottom of the collection box 1, a shaft 4 rotatably connected to the inner wall of the collection box 1, a mounting frame 5 fixedly connected to the outside of the shaft 4, a first filter screen 6 fixedly connected inside the mounting frame 5, and a frame 7 symmetrically fixedly connected to the inner wall of the collection box 1 and below the mounting frame 5. A limit rod 8 is slidably connected inside the frame 7. A rubber head 9 is fixedly connected to the top. When concrete waste is poured into the hopper 2, it will enter the collection box 1 under the force of gravity and be located on top of the mounting frame 5. It will be screened by the first filter screen 6. Then, the limiting rod 8 will slide so that the rubber head 9 will hit the bottom of the mounting frame 5. The mounting frame 5 will then rotate outside the insertion shaft 4, causing the mounting frame 5 to shake and accelerate the screening effect of the first filter screen 6. The screened cement will fall directly into the drawer 3 for collection.

[0025] Furthermore, in this embodiment, a limiting ring is fixedly connected to the bottom end of the limiting rod 8, and a roller 10 is rotatably connected to the bottom of the limiting rod 8. A spring 11 is sleeved on the outside of the limiting rod 8 and located between the frame 7 and the limiting ring. When the limiting rod 8 is lifted, the limiting ring will move synchronously with the limiting rod 8 and squeeze the spring 11. When the limiting rod 8 is released, the extension and retraction energy of the spring 11 is released, thereby resetting the limiting rod 8.

[0026] Furthermore, in this embodiment, a track 12 is fixedly connected to the bottom of the inner side of the frame 7, and a moving block 13 is slidably connected to the top of the track 12. The moving block 13 has an inclined structure design, and a sliding rod 14 is fixedly connected to the back of the moving block 13. The sliding rod 14 extends to the outside of the frame 7 and is slidably connected to the frame 7. By sliding the moving block 13 inside the track 12, the moving block 13 moves along a straight line, and one side of its inclined surface contacts the roller 10, thereby lifting the roller 10 and lifting the limiting rod 8.

[0027] Furthermore, in this embodiment, a partition 15 is fixedly connected between the two sets of frames 7. A mounting bracket 16 is fixedly connected to the bottom end of the partition 15. A slide rail 17 is fixedly connected to the top of the mounting bracket 16. A through groove is opened at the bottom end of the inner side of the slide rail 17. A slide plate 18 is slidably connected inside the slide rail 17. A slide rod 14 is fixedly connected to the slide plate 18. By moving the slide plate 18, the slide plate 18 will reciprocate inside the slide rail 17. When it moves, it will generate a pushing force on the slide rod 14. The slide rod 14 will transmit the motion force to the moving block 13.

[0028] Furthermore, in this embodiment, a disc 19 is rotatably connected to the outside of the mounting bracket 16, and a positioning post 20 is fixedly connected to the eccentric part of the disc 19. A swing rod 21 is rotatably connected to the bottom end of the mounting bracket 16. The swing rod 21 extends into the interior of the slide rail 17 and is rotatably connected to the bottom of the slide plate 18. A waist groove is formed inside the swing rod 21, and the positioning post 20 extends into the interior of the waist groove and is slidably connected to the waist groove. A guide plate 22 is fixedly connected to the outside of the collection box 1 and below the first filter screen 6. A second filter screen is fixedly connected inside the guide plate 22. By mounting a set of motors on the back of the mounting bracket 16, the motors... The output end is fixedly connected to the middle of the disc 19. Then the disc 19 will rotate, and the positioning column 20 will move synchronously with the disc 19 and squeeze the waist groove. The force on the waist groove will be transmitted to the swing rod 21. The bottom end of the swing rod 21 is the force point and it will swing back and forth, thereby realizing the reciprocating motion of the slide plate 18. As the mounting frame 5 tilts, the stones that cannot be screened on the first filter screen 6 will fall onto the guide plate 22. The impact force of the falling stones will cause the stones to vibrate, and the second filter screen will filter the concrete adhering to the outside of the stones again. The stones will slide out of the collection box 1 along the guide plate 22.

[0029] Furthermore, in this embodiment, an arc-shaped frame 23 is symmetrically fixedly connected to the inner side wall of the hopper 2, and crushing teeth are fixedly connected to the inner side wall of the arc-shaped frame 23. A rotating shaft 24 is rotatably connected to the middle of the arc-shaped frame 23, and extrusion plates are symmetrically fixedly connected to the outside of the rotating shaft 24. When the concrete waste enters the interior of the hopper 2, the rotating shaft 24 is driven to rotate by the motor. Subsequently, the extrusion plates collide the stones in the concrete with the crushing teeth to crush the large stones.

[0030] In this embodiment, the specific implementation scenario is as follows: Concrete waste is poured into the hopper 2, and a motor drives the rotating shaft 24 to rotate. The extrusion plate then collides the stones in the concrete with the crushing teeth, crushing large stones. Driven by gravity, the waste enters the collection box 1 and is located at the top of the mounting frame 5. It is then screened by the first filter screen 6. A set of motors is installed on the back of the mounting frame 16, with the motor output fixedly connected to the middle of the disc 19. The disc 19 then rotates, and the positioning column 20 moves synchronously with the disc 19, compressing the waist groove. The force on the waist groove is transmitted to the swing rod 21, whose bottom end is the force point, causing it to swing back and forth. This causes the sliding plate 18 to reciprocate, generating a thrust on the sliding rod 14. The sliding rod 14 then transmits the motion force to the moving plate. Moving block 13 then moves along a straight line, and one side of its inclined surface contacts roller 10, thereby lifting roller 10 and lifting one side of the limiting rod 8. At this time, the limiting ring moves synchronously with the limiting rod 8 and squeezes spring 11, so that rubber head 9 hits the bottom of mounting frame 5. Through the alternating rise of the limiting rod 8, mounting frame 5 rotates outside the insertion shaft 4, causing mounting frame 5 to shake and accelerate the screening effect of the first filter screen 6. The screened cement will fall directly into drawer 3 for collection. The stones that cannot be screened on the first filter screen 6 will fall onto the guide plate 22. The impact force of the falling stones will cause the stones to vibrate, and the second filter screen will filter the concrete adhering to the outside of the stones again. The stones will slide out of the collection box 1 along the guide plate 22.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
