[0024] See also Figure 1-4 ,

[0025] Embodiment 1: A construction waste crushing and recycling device includes a screening bin 1, bottom support columns 2 are evenly arranged around the bottom end of the screening bin 1, the bottom ends of the bottom support columns 2 are fixedly connected by a bottom connecting plate 3, a top crushing bin 4 is fixedly arranged on the top of the screening bin 1, the bottom end of the top crushing bin 4 is connected to the middle part of the top of the screening bin 1, two crushing rollers 5 are symmetrically rotated in the top crushing bin 4, the two crushing rollers 5 rotate in engagement with each other, two drive motors 6 are arranged on the side of the top crushing bin 4, the drive shaft of the drive motor 6 rotates through the top crushing bin 4 and is fixedly connected to the end of the crushing roller 5, and a metal waste recovery component 7 for crushing metal waste screening is provided on the screening bin 1.

[0026] The metal waste recycling component 7 includes a middle connecting plate 701 arranged inside the screening bin 1, a circular through hole 702 is provided in the middle of the middle connecting plate 701, two side discharge ports 703 are symmetrically provided on both sides of the screening bin 1, a guide plate 704 is provided at the bottom end of the side discharge port 703, a magnetic tray 705 is inserted into the circular through hole 702, a limiting support plate 706 is provided at the bottom of the screening bin 1, and the limiting support plate 706 is penetrated by the bottom support column 2 on all sides, and a servo motor 707 is installed on the top of the limiting support plate 706, and the output shaft of the servo motor 707 is connected to the middle part of the bottom end of the magnetic tray 705 through a driving connecting rod 708, and a lifting cylinder 709 is installed on the top of the bottom connecting plate 3, and the output shaft of the lifting cylinder 709 is connected to the bottom pull rod 710, and the top of the bottom pull rod 710 is connected to the middle part of the bottom end of the limiting support plate 706.

[0027] Embodiment 2: The difference between this embodiment and embodiment 1 is that the bottom of the screening bin 1 is open.

[0028] This makes it easier to take out the magnetic tray 705 disposed in the screening bin 1 .

[0029] Embodiment 3: The difference between this embodiment and embodiment 1 is that the bottom end of the top crushing bin 4 is inclined inward, and the bottom end of the top crushing bin 4 is connected to the top end of the screening bin 1.

[0030] The garbage crushed by the two crushing rollers 5 in the top crushing bin 4 can fall to the top of the magnetic tray 705 in a more concentrated manner.

[0031] Embodiment 4: The difference between this embodiment and embodiment 1 is that the magnetic tray 705 extends to the top of the circular through hole 702 , and arc-shaped blocking pieces are evenly arranged around the top of the magnetic tray 705 .

[0032] The crushed garbage at the bottom of the top crushing bin 4 falls to the top of the magnetic tray 705. The baffles arranged on the side of the magnetic tray 705 can slow down the rate of garbage discharge and increase the magnetic tray 705's ability to absorb more metal garbage.

[0033] In this embodiment, due to the lack of corresponding metal screening mechanism in the actual use of the existing construction waste crushing and recycling device, many metal materials such as iron wire contained in the construction waste will be mixed with other materials, requiring manual sorting at a later time. The sorting process is time-consuming and labor-intensive, greatly consumes the workers' physical strength, and is inconvenient for users to use.

[0034] In summary, in the specific implementation, when the user puts the construction and decoration waste into the top crushing bin 4, after starting the drive motor 6, the drive motor 6 can drive the two crushing rollers 5 to rotate in opposite directions, thereby crushing the garbage into small particles. The crushed garbage particles enter the top of the magnetic tray 705 in the screening bin 1. Since the magnetic tray 705 itself has magnetic properties, the metal material contained in the garbage falls to the surface of the magnetic tray 705.

[0035] The garbage will be attracted by the magnetic tray 705 and fixed on the surface of the magnetic tray 705. At the same time, the servo motor 707 at the bottom of the magnetic tray 705 is started, and the servo motor 707 drives the magnetic tray 705 to rotate by driving the connecting rod 708, so as to speed up the discharge efficiency of the garbage that falls on the surface of the magnetic tray 705 and prevent other garbage from accumulating on the surface of the magnetic tray 705. After the rotation of the magnetic tray 705, those garbage that does not have metal properties are discharged through the side discharge port 703, thereby realizing the screening and sorting of metal garbage.

[0036] Since there is less metal material in the garbage, after using it for a period of time, the user can start the lifting cylinder 709, and the lifting cylinder 709 pulls the limit support plate 706 downward through the bottom pull rod 710, and the limit support plate 706 drives the servo motor 707 and the magnetic tray 705 to move downward, so that the metal particles adsorbed on the magnetic tray 705 can be moved downward from the screening bin 1, which is beneficial for workers to remove and recycle the metal adsorbed on the magnetic tray 705, and then screen out the metal materials contained in the garbage as much as possible, greatly reducing the labor intensity of manual sorting in the later stage, and making it more convenient for users to use.
