Description

Technical Field

[0001] This utility model relates to the field of resource utilization of construction waste, and in particular to an integrated crushing and sorting machine for concrete recycling. Background Technology

[0002] Reinforced concrete, as a fundamental material in modern construction, is made by scientifically proportioning cement, sand and gravel aggregates, and steel bars. It possesses high compressive strength, excellent durability, and strong structural plasticity, and is widely used in various infrastructure constructions such as residential buildings, bridges, tunnels, and water conservancy projects. During the demolition, renovation, or repair of engineering structures, reinforced concrete components need to be cut to achieve structural separation, dimensional adjustment, or material recycling.

[0003] Current reinforced concrete recycling technologies generally employ a step-by-step processing model of "crushing first, then sorting." First, the cutting waste is crushed in multiple stages using equipment such as jaw crushers, impact crushers, or hammer crushers, breaking large pieces of concrete into smaller aggregates. Then, magnetic separators, air separation equipment, or manual sorting are used to separate metallic impurities such as reinforcing bars from the crushed mixture. While this model achieves the physical separation of reinforcing bars and concrete, it requires multiple machines, including crushing equipment, conveying devices, and sorting equipment, forming independent crushing and sorting units. This results in complex equipment connections and frequent material transfers.

[0004] The separation of crushing and sorting equipment leads to a lengthy process flow, requiring materials to be transferred and unloaded multiple times, which increases energy consumption and extends the processing cycle. The sorting process is highly dependent on human experience or semi-automated equipment and is easily affected by factors such as uneven distribution of crushed stone particle size and differences in the shape of steel bars, resulting in missed sorting, incorrect sorting, or incomplete sorting. Utility Model Content

[0005] To overcome the inefficiency of sorting, this utility model provides an integrated crushing and sorting machine for concrete recycling, aiming to solve the above-mentioned shortcomings.

[0006] A crushing and sorting machine for concrete recycling includes a first support frame, a base connected to the bottom of the first support frame, a guide plate connected to the rear end of the first support frame, a second support frame connected to the front end of the first support frame, a crusher mounted on the top of the second support frame, an mounting frame on the first support frame, a conveyor belt installed inside the mounting frame, a controller mounted on the side of the second support frame, a magnet located at the rear end inside the mounting frame and attached to the inner side of the conveyor belt, the upper end of the conveyor belt located at the bottom of the crusher, the lower end of the conveyor belt located at the top of the guide plate, a recycling cover connected to the bottom of the mounting frame and slidably connected to the first support frame, a collection box slidably connected to the base, a wired connection between the controller and the second support frame, and a vibration component located at the connection between the first support frame and the recycling cover for leveling the material conveyed on the conveyor belt.

[0007] Furthermore, the vibration assembly includes a motor, a mounting plate is connected to the top front side of the first support frame, the motor is mounted on the mounting plate, a top plate is connected to the front side of the recovery hood, a contact block is connected to the output shaft of the motor, the motor is wired to the controller, the contact block is pressed against the top plate, guide rods are connected to the left and right sides of the recovery hood, the guide rods are slidably connected to the first support frame, and a return spring is sleeved on the guide rod. One end of the return spring is connected to the recovery hood, and the other end is connected to the first support frame.

[0008] Furthermore, a baffle is connected to the front side of the mounting bracket.

[0009] Furthermore, the base has two pre-drilled slots on its front side.

[0010] Furthermore, a limiting plate is connected to the middle of the base, and the limiting plate cooperates with the rear end of the collection box for limiting.

[0011] Furthermore, the guide rod of the recycling hood is fitted with a telescopic sleeve, the inner diameter of which is larger than the outer diameter of the reset spring. One end of the telescopic sleeve is connected to the first support frame, and the other end is connected to the recycling hood.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. By coordinating the upper and lower positions of the crusher and the conveyor belt, the crushed mixture falls directly onto the surface of the conveyor belt, achieving continuous crushing and conveying operations and efficiently transferring materials.

[0014] 2. By embedding magnets into the conveyor belt, the steel bars are magnetically attracted and adhered during the conveying process, while non-magnetic materials slide into the guide plate due to gravity, thus achieving effective separation of steel bars and non-magnetic materials and improving sorting efficiency.

[0015] 3. The periodic squeezing action between the motor-driven contact block and the top plate in the vibration assembly causes the recycling hood to sway left and right, which in turn causes the mounting frame and conveyor belt to vibrate synchronously. This achieves the loosening effect of the crushed material, avoids the cement block being raised so that the steel bars cannot adhere to the conveyor belt, and ensures the stability of magnetic separation.

Detailed Implementation

[0022] The embodiments of this utility model will be described below with reference to the accompanying drawings.

[0023] Example: A crushing and sorting machine for concrete recycling, such as... Figures 1-5As shown, the system includes a base 1, a first support frame 2, a mounting frame 3, a conveyor belt 4, a controller 401, a second support frame 5, a crusher 6, a magnet 7, a recovery cover 8, a guide plate 9, a collection box 10, and a vibration assembly. The base 1 is connected to the bottom of the first support frame 2. The base 1 adopts a thickened steel plate welded structure to enhance the overall stability of the equipment. The guide plate 9 is inclined and connected to the rear end of the first support frame 2, forming a 45° material guiding slope. The guide plate 9 is designed with an inclined smooth inner wall to reduce material jamming. The second support frame 5 is connected to the front end of the first support frame 2. The crusher 6 is installed on the top of the second support frame 5. The mounting frame 3 is set on the first support frame 2, and the conveyor belt is installed inside the mounting frame 3. 4. A controller 401 is installed on the side of the second support frame 5. A magnet 7 is installed at the rear end of the mounting frame 3. The magnet 7 is embedded in the lower layer inside the conveyor belt 4, maintaining a gap of 2-3mm with the running surface of the conveyor belt. The upper end of the conveyor belt 4 is located at the bottom of the crusher 6, and the lower end of the conveyor belt 4 is located at the top of the guide plate 9. A recycling cover 8 is connected to the bottom of the mounting frame 3. The recycling cover 8 is slidably connected to the first support frame 2. A collection box 10 is slidably connected to the base 1. The collection box 10 is located at the bottom of the lower opening of the recycling cover 8. The controller 401 is wired to the second support frame 5. A vibration component is installed at the connection between the first support frame 2 and the recycling cover 8. The vibration component is used to level the material conveyed on the conveyor belt 4.

[0024] like Figure 1 , Figure 4 and Figure 5 As shown, the vibration assembly includes a mounting plate 11, a return spring 12, a top plate 13, a contact block 14, and a motor 15. The mounting plate 11 is connected to the top front side of the first support frame 2, and the motor 15 is mounted on the mounting plate 11. The top plate 13 is connected to the front side of the recovery cover 8. The output shaft of the motor 15 is connected to the contact block 14. The motor 15 is wired to the controller 401. The contact block 14 has an eccentric wheel structure. When rotating, it periodically squeezes the top plate 13 to form a reciprocating thrust. Guide rods are connected to the left and right sides of the recovery cover 8. The guide rods are slidably connected to the first support frame 2. The surface of the guide rods is chrome-plated to reduce sliding friction resistance, improve the smoothness of the vibration assembly's operation, and ensure stable material loosening effect. The guide rods are fitted with a return spring 12. One end of the return spring 12 is connected to the recovery cover 8, and the other end is connected to the first support frame 2. The return spring 12 is made of high-carbon manganese steel, which has excellent elasticity and fatigue resistance, ensuring rebound performance under long-term high-frequency vibration.

[0025] like Figure 1 As shown, it also includes a baffle 16. The front side of the mounting bracket 3 is connected to the baffle 16. The baffle 16 adopts a wear-resistant rubber edge design, which can prevent material from splashing and buffer impact.

[0026] like Figure 1 As shown, there are two reserved slots 17 on the front side of the base 1.

[0027] like Figure 2 As shown, it also includes a limiting plate 18, which is connected to the middle of the base 1, and the limiting plate 18 is matched with the rear end of the collection box 10 for limiting.

[0028] like Figure 2 As shown, it also includes a telescopic sleeve 19. The guide rod of the recovery cover 8 is fitted with a telescopic sleeve 19. The inner diameter of the telescopic sleeve 19 is larger than the outer diameter of the return spring 12. One end of the telescopic sleeve 19 is connected to the first support frame 2, and the other end is connected to the recovery cover 8. The telescopic sleeve 19 is made of weather-resistant rubber material, which ensures both the freedom of telescopic movement and forms a sealed protective space.

[0029] Workers use hoisting equipment to lift waste concrete blocks to the top feed inlet of crusher 6. After starting the equipment, crusher 6 crushes the concrete blocks using its internal grinding wheels, initially separating the cement blocks, gravel, and reinforcing steel. The separated mixture falls onto the surface of conveyor belt 4 below under gravity. At this point, the baffle 16 on the front side of the mounting frame 3 forms a physical barrier to prevent the material from slipping off the front side during transport, ensuring stable material transmission along conveyor belt 4.

[0030] The conveyor belt 4 continuously transports materials backward. When the mixture containing reinforcing bars passes through the area of ​​magnet 7, the magnetic field generated by magnet 7 causes the reinforcing bars to be magnetically attracted and adhered to the surface of the conveyor belt 4, moving synchronously with it. Non-magnetic materials such as cement blocks and gravel, due to the inclination angle of the conveyor belt 4 and gravity, separate from the reinforcing bars at the lower end of the conveyor belt 4 and slide into the guide plate 9, eventually entering the container at the end of the guide plate 9. The reinforcing bars adsorbed on the surface of the conveyor belt 4 move forward after the conveyor belt 4 turns. When they pass through the area of ​​magnet 7 and enter the non-magnetic attraction area, the reinforcing bars naturally fall off due to the loss of magnetic attraction, slide down the inner wall of the recovery hood 8 to the bottom opening, and finally fall into the collection box 10 directly below, completing the collection of reinforcing bars.

[0031] During the crushing and conveying process, the controller 401 synchronously activates the vibration assembly: the motor 15 drives the contact block 14 to rotate continuously, and the contact block 14 periodically makes pressing contact with the top plate 13. Through the top plate 13, the recovery cover 8 is pushed to slide laterally left and right on the guide rod. When the contact block 14 disengages from the top plate 13, the elastic force of the return spring 12 pushes the recovery cover 8 to quickly return to its original position, forming a left-right swaying mechanical action. This swaying is transmitted to the mounting frame 3 and the conveyor belt 4, which loosens the crushed material on the conveyor belt 4, preventing materials such as cement blocks from accumulating or being raised on the surface of the conveyor belt 4. This ensures that the reinforcing bars always remain in contact with the surface of the conveyor belt 4, so that they can be stably attracted by the magnet 7, preventing the magnetic attraction from failing due to the material being raised.

[0032] After all material processing is completed, the staff first shuts off the power to the crusher 6 and the motor 15. Then, using a forklift, they insert it into the bottom of the collection box 10 through the two pre-reserved slots 17 on the front side of the base 1, and smoothly lift the collection box 10 containing the steel bars out of the equipment. After that, the empty collection box 10 is pushed along the surface of the base 1 directly below the bottom opening of the recovery cover 8. At this time, the limiting plate 18 in the middle of the base 1 limits and constrains the rear end of the collection box 10, ensuring that the opening of the collection box 10 is aligned with the bottom opening of the recovery cover 8, and preventing material spillage. During the compression and rebound process of the top plate 13, the telescopic sleeve 19 on the outside of the guide rod extends and retracts synchronously, forming a sealed protective space to prevent dust and gravel from entering the area of ​​the guide rod and the return spring 12, ensuring the long-term stable operation of the vibration assembly.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
