[0020] Refer to the attached Figure 1 and 2The utility model is a concrete crushing and recycling device, the main structure of which includes a recycling box 1, which is a hollow structure made of metal material. A feed inlet 2 is provided on the top of the recycling box 1, and the block concrete to be recycled enters the recycling box 1 from the feed inlet 2. A crushing roller 3 is symmetrically connected to the lower part of the feed inlet 2. The crushing roller 3 is driven to rotate by a power motor 14. A plurality of crushing teeth are distributed on the surface of the crushing roller 3. The crushing of the block concrete is achieved by the rotation of the two crushing rollers 3. The lower part of the crushing roller 3 is provided with a There is a primary screening plate 4, which is welded or bolted to the inner wall of the recovery box 1. A plurality of sieve holes 5 are arranged on the primary screening plate 4 below the crushing roller 3. The size of the sieve holes 5 is determined according to the size of the qualified concrete after crushing, so that the qualified concrete particles in the crushed concrete pass through the sieve holes 5, while the unqualified large-particle concrete blocks are left on the primary screening plate 4. Channel openings 6 are symmetrically arranged at both ends of the primary screening plate 4. The channel openings 6 vertically penetrate the primary screening plate 4. The opening size of the channel openings 6 is much larger than the sieve holes 5, so that large pieces of concrete can pass through. The concrete that is not qualified is discharged through the discharge port 8 of the recycling chamber 7 and directly enters the subsequent recycling procedure, while the unqualified concrete is discharged through the circulation port 10 of the circulation chamber 9 and is repeatedly crushed again after being collected, so as to realize accurate separation of the crushed concrete, reduce the increased power consumption and energy waste caused by repeated crushing of qualified concrete, improve the overall crushing efficiency of concrete, and reduce the cost of crushing and recycling. A push rod 11 is connected to the upper part of the primary screening plate 4 along the lateral sliding. The setting of the push rod 11 can be used to push the large pieces of concrete remaining on the primary screening plate 4 toward the channel opening 6. During the pushing process, the qualified small particles of concrete mixed therein fall through the sieve hole 5, so as to realize further screening of the concrete. During the pushing process, the blockage of the primary screening plate 4 by large pieces of concrete can be avoided, which further improves the screening efficiency.
[0021] Preferably, both ends of the push rod 11 are provided with sliders 12, and the sliders 12 are slidably connected to the side walls of the recycling box 1. Specifically, slide rails are arranged on the opposite side walls of the recycling box 1, and a penetrating slide hole is arranged on one of the side walls. The slider 12 on one side is slidably connected to the internal slide rail, and the slider 12 on the other side is located outside the recycling box 1. One end of the push rod 11 passes through the slide hole and is connected to the slider 12, and the external slider 12 is also slidably connected to the slide rail. A power rod 13 for driving one of the sliders 12 to slide horizontally is provided on the outside of the recycling box 1, and the power rod 13 is used to drive the external slider 12 to slide. Such a structure utilizes the power rod 13 to drive the push rod 11 to slide horizontally smoothly, thereby realizing the pushing and moving of large-particle concrete. The structure is simple, and the separation of large blocks of concrete is smoother and more efficient.
[0022] Preferably, see Attachment Figure 3 The outside of the recycling box 1 is fixed with a motor 14 by welding or bolts, and the power rod 13 is welded or bolted to the output shaft of the motor 14. The motor 14 is used to drive the power rod 13 to rotate. The power rod 13 passes through one of the sliders 12 and is threadedly connected with it. Such a structure indirectly realizes the lateral sliding drive of the push rod 11 by the power rod 13.

The recovery box 1 is provided with a power component for driving the push rod 11 to rotate. With this structure, when the push rod 11 slides horizontally, the power component can also synchronously drive the push rod 11 to rotate, thereby driving the roller 15 outside the push rod 11 to rotate. The setting of the roller 15 increases the contact area with large pieces of concrete, further improving the efficiency of concrete separation. The rotation setting of the push rod 11 and the roller 15 makes the resistance when pushing the concrete to move smaller, and the separation of large pieces of concrete is smoother.
[0023] Preferably, the power assembly includes a gear 16 and a rack 17, the gear 16 is welded or bolted to the end of the push rod 11, the rack 17 is welded or bolted to the outer wall of the recovery box 1, the gear 16 is meshed with the rack 17, such a structure when the power rod 13 drives the push rod 11 to slide horizontally, the gear 16 meshes and rotates on the rack 17, thereby realizing the rotation drive of the push rod 11, the structure is simple, the number of driving structures is simplified, and the energy utilization rate is improved. A brush 18 is provided on the outside of the drum 15, and the setting of the brush 18 can further clean the sieve hole 5 through the rotation of the drum 15, further avoiding the blockage of the sieve hole 5, and ensuring the patency of the primary screening plate 4 under long-term use.
[0024] Preferably, a secondary sieve plate 19 is provided in the circulation chamber 9, and the secondary sieve plate 19 is welded or bolted to the inner wall of the circulation chamber 9. The circulation port 10 is located above the secondary sieve plate 19. A discharge port 8 is also provided at the bottom of the circulation chamber 9, and the discharge port 8 is located below the secondary sieve plate 19. This arrangement utilizes the secondary sieve plate 19 to perform secondary screening on the large-particle concrete falling from the channel port 6, thereby reducing the content of qualified-size concrete therein and further improving the accuracy of screening after concrete crushing.
[0025] Preferably, a guide plate 20 is symmetrically welded or bolted below the crushing roller 3, and the guide plate 20 is inclined toward the sieve hole 5. Such a structure allows the crushed concrete to fall directly toward the sieve hole 5, preventing the concrete from falling directly from the channel openings 6 at both ends, thereby ensuring the accuracy of concrete screening.
[0026] Working principle: The utility model symmetrically arranges crushing rollers 3 in the recycling box 1, so that the concrete blocks entering from the feed port 2 fall on the primary screening plate 4 after being crushed, and the concrete particles with qualified crushing degree pass through the sieve holes 5 on the primary screening plate 4 and fall into the recycling chamber 7, and are discharged from the discharge port 8 of the recycling chamber 7 for direct recycling, while the large pieces of concrete with insufficient crushing degree fall into the circulation chamber 9 through the channel ports 6 on both sides, and are discharged from the circulation port 10 on the circulation chamber 9, and are collected and crushed again in a circulation manner, so that the crushed concrete can be accurately separated and screened, reducing the qualified concrete particles. The increased power consumption and energy waste caused by repeated crushing of concrete can be reduced, the overall crushing efficiency can be improved, and the cost of crushing and recycling can be reduced; a push rod 11 is connected to the upper side of the primary screen plate 4 along the transverse sliding. This structure allows the large-particle concrete blocks accumulated on the primary screen plate 4 to be pushed into the channel openings 6 on both sides by the transversely sliding push rod 11. During the pushing process, the qualified concrete particles mixed in the large-particle concrete blocks also gradually pass through the sieve holes 5 and enter the recovery chamber 7. This structure realizes the accurate separation of large-particle concrete blocks, while avoiding the blockage of the primary screen plate 4, greatly improving the screening efficiency of the crushed concrete.
