[0019] 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.
[0020] Example 1
[0021] Please refer to Figure 1-5 As shown, this utility model provides a concrete block processing device, including a base frame 1. The top of the base frame 1 is connected to a processing box 3 via four sets of support plates 2. The top of the processing box 3 is provided with a feed hopper 4, and the bottom is provided with a discharge port 19. The interior is provided with a primary crushing chamber 6 near the top and a primary crushing mechanism is installed thereon. Below the primary crushing chamber 6, a secondary crushing chamber 7 is provided and a secondary crushing mechanism is installed thereon. The top of the base frame 1 is provided with a screening mechanism below the discharge port 19 to facilitate the screening of the crushed concrete blocks.
[0022] Specifically, waste concrete blocks are first fed into the feed hopper 4 at the top of the processing tank 3. The concrete blocks enter the primary crushing chamber 6 near the top inside the processing tank 3. The primary crushing mechanism inside the chamber can perform preliminary crushing of the concrete blocks. The material after preliminary crushing can fall into the secondary crushing chamber 7 located below the primary crushing chamber 6. The secondary crushing mechanism can further refine the material. The crushed material can be discharged through the discharge port 19 at the bottom of the processing tank 3 and fall onto the screening mechanism. The screening mechanism can screen the crushed concrete blocks and separate recycled aggregates of different particle sizes, thus completing the processing of concrete blocks. Through the above structure, the graded crushing and automatic screening of concrete blocks can be realized. The processing flow is continuous, improving the recycling efficiency of concrete blocks.
[0023] The primary crushing mechanism includes crushing rollers 12. Two sets of first connecting shafts 8 are rotatably connected to the inner side of the primary crushing chamber 6. One end of each set of first connecting shafts 8 extends to the outside of the processing box 3 and is connected to a spur gear 9. The two sets of spur gears 9 mesh with each other. One side of one set of spur gears 9 is connected to the output end of a first motor 10. The first motor 10 is mounted on the top of a mounting base 11 located on one side of the processing box 3. Crushing rollers 12 are sleeved on the outer rings of the two sets of first connecting shafts 8 on the inner side of the primary crushing chamber 6. When the primary crushing mechanism is working, starting the first motor 10 allows its output end to drive the connected set of spur gears. As wheel 9 rotates, the two sets of spur gears 9 mesh with each other and are respectively connected to one end of the two sets of first connecting shafts 8 extending to the outside of the processing box 3. Therefore, the other set of spur gears 9 can rotate in the opposite direction, which in turn can drive the two sets of first connecting shafts 8 inside the primary crushing chamber 6 to rotate synchronously in the opposite direction. The crushing rollers 12 sleeved on the outer ring of the two sets of first connecting shafts 8 can rotate synchronously in the opposite direction with the shafts, so as to squeeze and shear the concrete blocks entering the primary crushing chamber 6 to achieve preliminary crushing. Thus, by setting up, the concrete blocks can be efficiently crushed in the initial stage, providing materials of suitable particle size for subsequent secondary crushing and improving the overall crushing efficiency.
[0024] The inner side of the primary crushing chamber 6 is equipped with two sets of inclined guide plates 5 near the top. These two sets of guide plates 5 can accurately guide the concrete blocks falling from the feed hopper 4 between the two sets of crushing rollers 12, preventing the material from deviating from the crushing area and causing accumulation. At the same time, they can slow down the falling speed of the material and ensure more thorough initial crushing.
[0025] The secondary crushing mechanism includes hammer plates 16. A second connecting shaft 13 is rotatably connected to the inner side of the secondary crushing chamber 7. One end of the second connecting shaft 13 is connected to the output end of a second motor 14 installed on one side of the processing box 3. A rotating drum 15 is sleeved on the outer ring of the second connecting shaft 13. Multiple sets of hammer plates 16 are evenly distributed circumferentially on the outer surface of the rotating drum 15. A first impact plate 17 and a second impact plate 18, which cooperate with the hammer plates 16, are installed on one side of the secondary crushing chamber 7, diagonally above the rotating drum 15. Both the first impact plate 17 and the second impact plate 18 are arc-shaped. When the secondary crushing mechanism is working, the second motor 14 is started, and its output end can drive the second connecting shaft 13 rotatably connected to the inner side of the secondary crushing chamber 7 to rotate. The rotating drum 15, which is sleeved on the outer ring of the second connecting shaft 13, can rotate synchronously with the shaft. Multiple sets of hammer plates 16, which are evenly distributed circumferentially on the outer surface of the rotating drum 15, can rotate at high speed with the rotating drum 15. The material falling from the primary crushing chamber 6 into the secondary crushing chamber 7 can be impacted by the rotating hammer plates 16 and thrown towards the arc-shaped first impact plate 17 and second impact plate 18. After the material rebounds from the impact plate, it can be impacted by the hammer plates 16 again. Through the cycle of "hammering-rebounding-hammering", the material can be further finely crushed. Furthermore, by setting it up, the initially crushed material can be impacted and crushed multiple times to refine the material to a more uniform particle size, providing high-quality material for subsequent screening and improving the crushing quality of concrete blocks.
[0026] The screening mechanism includes a vibrating motor 25. Screen frames 20 are connected to the top four corners of the base frame 1 via springs 24. A screen mesh 21 is located at the bottom of the screen frame 20, with a discharge port 22 at one end and a guide hopper 23 at the bottom. A vibrating motor 25 is installed on one side of the screen frame 20. When the screening mechanism is working, the vibrating motor 25 is activated, and the vibration force generated by the vibrating motor 25 drives the screen frame 20 to vibrate. Since the screen frame 20 is connected via springs 24 at the top four corners of the base frame 1, the springs 24 can buffer the vibration impact and strengthen the screen frame. The vibration effect of screen 20 allows concrete blocks discharged from the discharge port 19 to fall onto the screen 21 at the bottom of the screen frame 20. Under the vibration, aggregates with a particle size smaller than the mesh size of the screen 21 can pass through the screen 21 into the guide hopper 23 below and be discharged, while aggregates with a particle size larger than the mesh size of the screen 21 can move along the screen 21 towards the discharge port 22 at one end of the screen frame 20 and be discharged. This achieves the separation of aggregates of different particle sizes. Furthermore, by setting up the screen, it is possible to efficiently separate aggregates of different particle sizes, thereby improving screening efficiency and aggregate recycling rate.
[0027] Working principle: First, waste concrete blocks are fed into the feed hopper 4 at the top of the processing box 3. The concrete blocks fall into the primary crushing chamber 6, and the primary crushing mechanism is activated simultaneously. The first motor 10 drives a set of sprockets 9 to rotate. Through the two sets of meshing sprockets 9, the two sets of first connecting shafts 8 inside the primary crushing chamber 6 rotate synchronously in opposite directions. The crushing rollers 12, which are sleeved on the outer rings of the two sets of first connecting shafts 8, rotate in opposite directions with the shafts, thereby squeezing and shearing the concrete blocks to achieve preliminary crushing. The material after preliminary crushing falls into the secondary crushing chamber 7 below. The second motor 14 is activated, and its output end drives the second connecting shaft 13 inside the secondary crushing chamber 7 to rotate. The rotating drum 15, which is sleeved on the outer ring of the second connecting shaft 13, rotates synchronously. Multiple sets of rollers 15 are distributed circumferentially on the outer surface of the rotating drum 15. The high-speed rotation of the hammer plate 16 can impact and throw the material against the first impact plate 17 and the second impact plate 18. After rebounding from the impact plate, the material can be impacted again by the hammer plate 16. Through the cyclic action, fine crushing can be completed. The crushed material can be discharged through the discharge port 19 at the bottom of the processing box 3 and fall into the screening mechanism at the top of the base frame 1. The vibrating motor 25 can drive the screen frame 20 to vibrate. The spring 24 can buffer the impact and enhance the vibration effect. After the material falls on the screen 21 at the bottom of the screen frame 20, the aggregate with a particle size smaller than the mesh size of the screen 21 can pass through the screen 21 and enter the lower guide bin 23 and be discharged. The aggregate with a particle size larger than the mesh size can move along the screen 21 to the discharge port 22 at one end of the screen frame 20 and be discharged. Finally, the crushing and screening of concrete blocks is completed, thus completing the entire operation process.
