Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0031] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The utility model provides an embodiment: a recycled concrete crushing and screening device, including a bottom plate 1, a double-shaft motor 19 is fixedly connected to the top of the bottom plate 1, a transmission rod 18 is fixedly connected to the output end of the double-shaft motor 19, and an eccentric wheel 12 is fixedly connected to both ends of the transmission rod 18, a material box 2 is fixedly connected to the top of the bottom plate 1, a filter screen 24 is rotatably connected to the inside of the material box 2, and two connecting rods 25 are fixedly connected to the outside of the filter screen 24. A rotating plate 5 is fixedly connected to the outside of the two connecting rods 25, and a T-shaped slot 6 is provided on the outside of the rotating plate 5. A T-shaped block 7 is slidably connected to the inside of the T-shaped slot 6, and a fixed rod 8 is rotatably connected to the outside of the T-shaped block 7.

The bottom of 8 is fixedly connected with an extrusion plate 11, a moving component is installed on the outside of the material box 2, U-shaped holes 4 are opened on both sides of the outside of the material box 2, the outsides of two U-shaped holes 4 are slidably connected to the outside of the connecting rod 25, and the outsides of the other two U-shaped holes 4 are rotatably connected to the outside of the material box 2, both sides of the outside of the material box 2 are fixedly connected with limit blocks 9, the outside of the limit blocks 9 is slidably connected to the fixed rod 8, two consolidation blocks 20 are fixedly connected to the top of the bottom plate 1, the outside of the consolidation blocks 20 is rotatably connected with the transmission rod 18, a discharge port 26 is fixedly connected to one side of the outside of the material box 2, one end of the spring 10 is fixedly connected to the top of the extrusion plate 11, and the other end of the spring 10 is fixedly connected to the bottom of the limit block 9.
[0032] Specifically, a double-axis motor 19 is installed on the top of the base plate 1. Under the action of the consolidation block 20, the transmission rod 18 is stabilized, so that the double-axis motor 19 can stably drive the rotation of the transmission rod 18, and then the rotation of the transmission rod 18 drives the eccentric wheel 12 to rotate. A plurality of structures are installed inside the material box 2, which are used to crush and classify concrete. Under the action of the filter 24, the crushed concrete can be classified. The eccentric wheel 12 hits the extrusion plate 11, so that the fixed rod 8 slides along the outer side of the limit block 9. Under the action of the limit block 9, the fixed rod 8 is limited. Under the action of the spring 10, the up and down sliding of the fixed rod 8 is assisted and stabilized, so that the fixed rod 8 and the T-block 7 rotate, and then the T-block 7 is driven to slide along the inner wall of the T-slot 6. , so that the rotating plate 5 can rotate up and down by a small amplitude. Under the action of the rotating plate 5, two of the connecting rods 25 are driven to slide along the outer side of the U-shaped hole 4, and the other two connecting rods 25 rotate with the outer sides of the material box 2, so that the rotating plate 5 can always rotate around a point, which ensures the effectiveness of the structure to a certain extent. Then, under the action of two of the connecting rods 25, the filter screen 24 slides inside the material box 2, so that the filter screen 24 can achieve a vibration effect, which can be more effective in filtering and classifying crushed concrete, speeding up the classification speed, and preventing concrete from clogging the filter screen 24. Fine concrete will pass through the through holes of the filter screen 24 and enter the inner bottom of the material box 2. Large pieces of concrete are discharged through the discharge port 26 under the rotation of the filter screen 24, thereby achieving an effect of classifying concrete.
[0033] Reference Figure 1 , Figure 2 and Figure 3 The moving component includes a mounting block 3, which is fixedly connected to one side of the outside of the material box 2. A sliding groove 21 is opened inside the mounting block 3. Two single-axis motors 14 are slidably connected to the inner wall of the sliding groove 21. A rotating rod 23 is fixedly connected to the output end of the single-axis motor 14. A crushing roller 22 is fixedly connected to the inside and outside of the rotating rod 23. A threaded block 15 is rotatably connected to one end of the rotating rod 23. A fixed block 13 is fixedly connected to the other side of the outside of the material box 2. A threaded rod 16 is rotatably connected to the inside of the fixed block 13. The two threaded blocks 15 are slidably connected to the inside of the fixed block 13. The threaded block 15 and the threaded rod 16 are threadedly connected. The two rotating rods 23 are slidably connected to the outside of the two sliding holes 17.
[0034] Specifically, the mounting block 3 is used to assist in supporting and moving the single-axis motor 14. The mounting block 3 is fixed on the outside of the material box 2 to ensure its fixation. A sliding groove 21 is provided inside the mounting block 3 so that the single-axis motor 14 can slide inside the mounting block 3. Under the action of the output end of the mounting block 3, the rotating rod 23 is driven to rotate, so that the rotating rod 23 drives the rotation of the crushing roller 22, so that the concrete can be crushed. Under the action of the two rotating rods 23, the crushing power is improved and the effectiveness of the crushing is ensured. The fixed block 13 provides a movement space for the threaded rod 16 and the two threaded blocks 15. By rotating the threaded rod 16, the two threaded blocks 15 are threaded along the outside of the threaded rod 16, thereby driving the rotating rod 23 to move in opposite directions, so that the two crushing rollers 22 can be close to or away from each other, thereby achieving an adjustable distance between the two crushing rollers 22, and then the particle size and fineness of the concrete crushing can be controlled, thereby improving the flexibility and adaptability of the equipment.
[0035] Working principle: when it is necessary to crush the recycled concrete, the threaded rod 16 is rotated to make the threaded block 15 perform threaded movement along the outer wall of the threaded rod 16, thereby driving the movement of the rotating rod 23, and then driving the movement of the crushing roller 22, and then driving the movement of the single-axis motor 14, so that the distance between the two crushing rollers 22 can be adjusted, so that the crushing particle size and fineness of the concrete can be controlled according to actual needs. After adjustment, the two single-axis motors 14 are started, and the output end of the single-axis motor 14 drives the rotation of the rotating rod 23, and then drives the rotation of the crushing roller 22, so that the two crushing rollers 22 rotate inside the material box 2, so as to achieve a crushing effect. The crushed concrete will fall on the top of the filter screen 24. Under the action of the filter screen 24, the concrete is classified into particles. In order to filter more effectively, the double-axis motor 19 is started at this time. Under the action of the output end of the dual-axis motor 19, the eccentric wheel 12 is driven to rotate, so that different parts of the eccentric wheel 12 hit the bottom of the extrusion plate 11, so that the fixed rod 8 slides up and down along the outer side of the limit block 9, so that the fixed rod 8 and the T-shaped block 7 rotate, thereby driving the T-shaped block 7 to slide left and right along the inner wall of the T-shaped groove 6, so that the rotating plate 5 is attached to the outer side of the material box 2 and rotates slightly, and then drives two of the connecting rods 25 to slide along the outer side of the U-shaped hole 4, so that the connecting rod 25 drives the filter screen 24 to slide inside the material box 2, thereby achieving the effect of a vibrating filter screen 24, so that the broken concrete can be more fully filtered, so that small particles of concrete fall into the bottom of the material box 2 through the through holes of the filter screen 24, and large pieces of concrete are discharged from the discharge port 26 when the plane of the eccentric wheel 12 contacts the bottom of the extrusion plate 11, thereby achieving an effect of classifying the broken concrete.
