[0029] Reference Figure 1-7, a waste concrete separation equipment comprises a separation box 1, the bottom of the separation box 1 is connected with a blanking box 4, the side wall of the separation box 1 is provided with a feeding port 3, a second hydraulic cylinder 8 is fixedly installed on the top of the separation box 1, and a fixed block 9 is fixedly installed on the output end port of the second hydraulic cylinder 8, a first motor 10 is fixedly installed inside the fixed block 9, a connecting frame 11 is fixedly installed on the output shaft port of the first motor 10, the connecting frame 11 and the fixed block 9 are rotatably connected, a pressing plate 13 is rotatably connected to the bottom of the connecting frame 11, a crushing rod 15 is evenly fixedly installed on the bottom of the pressing plate 13, a through electromagnet 16 is fixedly installed on the top of the pressing plate 13, a screen frame 5 is slidably connected to the inside of the blanking box 4, concrete is poured into the interior of the separation box 1 through the feeding port 3 during use, and the screen frame 5 is used for support, at this time, the second hydraulic cylinder 8 is started, and the second hydraulic cylinder 8 drives the connecting frame 11 to move up and down, when the connecting frame 11 moves downward, the pressing plate 13 and the crushing rod 15 arranged at the bottom of the connecting plate can be used to crush the concrete, When 11 moves up and down for crushing, the first motor 10 can also be started, and the first motor 10 drives the entire connecting frame 11 to rotate, and the connecting frame 11 drives the pressing plate 13 to rotate synchronously, so that the crushing rod 15 at the bottom of the pressing plate 13 is used to poke the concrete, which is helpful for crushing processing, and also helps to make the crushed concrete leak from the screen frame 5 to the inside of the blanking box 4. After the concrete is crushed, the pressing plate 13 can be rotated to make the electromagnet 16 on the top of the pressing plate 13 rotate to the downward direction, so that the electromagnet 16 can be used to absorb the remaining steel bars in the concrete. At this time, all the concrete on the screen frame 5 falls into the blanking box 4, and the steel bars are also absorbed by the electromagnet 16, which can directly push the screen frame 5, and use the screen frame 5 to push the crushed concrete out of the blanking box 4. When the screen frame 5 is pushed to the outside of the blanking box 4, the electromagnet 16 is powered off, so that the absorbed steel bars fall into the blanking box 4, and when the screen frame 5 slides back, the steel bars can be directly pushed out from the other end, which is convenient for use.

[0030] Furthermore, the connecting frame 11 is composed of a circular plate, a circular ring and four connecting rods, the circular plate and the circular ring are distributed up and down, and the four connecting rods are fixedly installed between the circular plate and the circular ring, the pressure plate 13 is rotatably connected to the inside of the circular ring, and the circular plate and the fixed block 9 are rotatably connected.

[0031] Furthermore, a rotating shaft 14 is fixedly passed through the side wall of the pressing plate 13, and the pressing plate 13 is rotatably connected to the connecting frame 11 through the rotating shaft 14. A second motor 12 is fixedly installed inside the connecting frame 11, and an output shaft port of the second motor 12 is fixedly connected to the rotating shaft 14. The pressing plate 13 needs to be rotated after crushing the concrete so that the electromagnet 16 can work. At this time, the second motor 12 can be directly started, and the second motor 12 can drive the pressing plate 13 to rotate using the rotating shaft 14. Similarly, the crushing rod 15 can also be facing downward.

[0032] Furthermore, the side wall of the pressing plate 13 is provided with two symmetrical receiving grooves, an electric telescopic rod 17 is fixedly installed inside the receiving groove, and an insert block 18 is fixedly installed at the output port of the electric telescopic rod 17. The insert block 18 is slidably connected inside the receiving groove, and the inner wall of the connecting frame 11 is provided with two slots that are matched with the size of the insert block 18. In order to make the pressing plate 13 more stable during the concrete crushing process, the insert block 18 can be inserted into the slot of the circular ring, so that the pressing plate 13 can be stably restricted in the circular ring and will not be easily rotated by the rotating shaft 14. If rotation is required, the electric telescopic rod 17 can be used to drive the insert block 18 to retract into the receiving groove of the pressing plate 13.

[0033] Furthermore, both ends of the blanking box 4 are set to be openings, and the bottom wall of the separation box 1 is set to be a conical slope 2. By setting the conical slope 2, the pressure plate 13 and the breaking rod 15 can better act on the concrete, have a gathering effect on the concrete, and improve the convenience in use.

[0034] Furthermore, the screen frame 5 is composed of a filter plate, a connecting plate and two supporting legs. The connecting plate is fixedly installed at a position near the side wall at the bottom of the filter plate, and the two supporting legs are fixedly installed at a position at the bottom of the filter plate away from the connecting plate, and the two supporting legs are symmetrically arranged. The filter plate on the screen frame 5 can support concrete and enable the concrete to be screened after being crushed. The connecting plate can push out the crushed concrete or push out the steel bars, and the supporting legs serve the purpose of supporting the filter plate.

[0035] Furthermore, a telescopic baffle 6 and a first hydraulic cylinder 7 are fixedly installed on the side wall of the blanking box 4. The output port of the first hydraulic cylinder 7 is fixedly connected to the connecting plate. The telescopic end of the telescopic baffle 6 is fixedly connected to the connecting plate. The telescopic baffle 6 is an arc-shaped structure arranged above the first hydraulic cylinder 7. The telescopic baffle 6 is composed of a plurality of arc-shaped plates, and the plurality of arc-shaped plates are slidably connected. The push of the screen frame 5 can be driven by the first hydraulic cylinder 7. The telescopic baffle 6 can shield the first hydraulic cylinder 7 to reduce the possibility of the first hydraulic cylinder 7 being damaged by concrete.

[0036] In summary, during use, concrete is poured into the separation box 1 through the feed port 3, and supported by the screen frame 5. At this time, the second hydraulic cylinder 8 is started, and the second hydraulic cylinder 8 drives the connecting frame 11 to move up and down. When the connecting frame 11 moves downward, the pressing plate 13 and the crushing rod 15 arranged at the bottom of the connecting plate can be used to crush the concrete. When the connecting frame 11 moves up and down for crushing, the first motor 10 can also be started, and the first motor 10 drives the entire connecting frame 11 to rotate, and the connecting frame 11 drives the pressing plate 13 to rotate synchronously, so that the concrete is crushed by the crushing rod 15 at the bottom of the pressing plate 13. The concrete is moved by the screen frame 5, which helps to break the concrete and also helps to make the broken concrete leak from the screen frame 5 into the inside of the blanking box 4. After the concrete is broken, the pressing plate 13 can be rotated to make the electromagnet 16 on the top of the pressing plate 13 rotate downward, so that the electromagnet 16 can be used to absorb the remaining steel bars in the concrete. At this time, all the concrete on the screen frame 5 falls into the blanking box 4, and the steel bars are also absorbed by the electromagnet 16, which can directly push the screen frame 5, and use the screen frame 5 to push the broken concrete out of the blanking box 4. When the screen frame 5 is pushed to the outside of the blanking box 4, the electromagnet 16 is powered off, so that the adsorbed steel bars fall into the blanking box 4. When the screen frame 5 slides back, the steel bars can be directly pushed out from the other end, which is convenient for use. The pressing plate 13 needs to be rotated after crushing the concrete, so that the electromagnet 16 can work. At this time, the second motor 12 is directly started, and the second motor 12 drives the pressing plate 13 to rotate using the rotating shaft 14. Similarly, the crushing rod 15 can also be facing downward. In order to make the pressing plate 13 more stable in the process of crushing concrete, the plug block 18 can be inserted into the slot of the ring, so that the pressing plate 13 can be stable and limited. It is made in a circular ring and will not be easily rotated by the rotating shaft 14. If it needs to be rotated, the electric telescopic rod 17 can be used to drive the plug block 18 to retract into the receiving groove of the pressure plate 13. The filter plate on the screen frame 5 can support the concrete and enable the concrete to be screened after being crushed. The connecting plate can push out the crushed concrete or the steel bars. The supporting legs support the filter plate. The push of the screen frame 5 can be driven by the first hydraulic cylinder 7. The telescopic baffle 6 can block the first hydraulic cylinder 7 to reduce the possibility of the first hydraulic cylinder 7 being damaged by concrete.
