[0039] Embodiment 2

[0040] The scheme in embodiment 1 is further introduced in combination with specific working mode, and details are described below:

[0041] AsFigure 1 As shown, in a preferred embodiment, based on the above method, a sliding rod 201 is evenly and horizontally fixed on the inner side of the housing 1, and the sliding rod 201 extends into the interior of the mounting frame 2 and is slidably connected to the mounting frame 2.

[0042] During the horizontal sliding of the mounting frame 2, the slide rod 201 is used to limit its movement, ensuring the stability of the mounting frame 2 when it shakes.

[0043] like Figure 3 As shown, in a preferred embodiment, based on the above method, the reciprocating mechanism 4 further includes a first motor 401, a turntable 402 and a pull rod 403. The first motor 401 is mounted on the inner wall of the housing 1. The turntable 402 is mounted on the output end of the first motor 401. The pull rod 403 is rotatably mounted on the outer side of the turntable 402. The end of the pull rod 403 is hinged to the outer side of the mounting frame 2.

[0044] When controlling the sliding of the mounting frame 2, the first motor 401 is started to drive the rotation of the turntable 402. During the rotation of the turntable 402, the pull rod 403 is pulled and pushed, thereby controlling the reciprocating sliding of the mounting frame 2.

[0045] like Figure 3 As shown, in a preferred embodiment, based on the above method, the translation mechanism 5 further includes a C-shaped plate 501, a second motor 502, a screw 503, and a fixing block 504. The C-shaped plate 501 is fixed on the side of the mounting frame 2. The second motor 502 is installed at the middle position of the side of the C-shaped plate 501. The screw 503 is installed at the output end of the second motor 502. The fixing block 504 is fixed on the side of the screening screen plate 3. The screw 503 and the fixing block 504 are threadedly connected.

[0046] After screening and filtration, large particles are located at the top of the screening screen plate 3. The second motor 502 is started to control the screw 503 to rotate. The rotation of the screw 503 drives the fixed block 504 to move along the length of the screw 503, thereby pulling the screening screen plate 3 horizontally out. When the screening screen plate 3 is pulled out horizontally, the large particles at the top are blocked by the side of the screening screen plate 3 and fall downward.

[0047] like Figure 3 As shown, in a preferred embodiment, based on the above method, the side of the mounting frame 2 is provided with an opening that cooperates with the screening screen plate 3, and the top of the opening is provided with a rubber scraper that fits against the surface of the screening screen plate 3.

[0048] During the sliding process of the screening screen plate 3, the rubber scraper is closely attached to the surface of the screening screen plate 3 to ensure that large particles of material fall off completely.

[0049] likeFigure 4 As shown, in a preferred embodiment, based on the above method, the dust removal mechanism 6 further includes a scraper 601 and a vertical rod 602. The scraper 601 is attached to the inner side of the breathable mesh 105, and the length of the scraper 601 is the same as the length of the breathable mesh 105. The top of the scraper 601 is fixed with the vertical rod 602, and the top of the vertical rod 602 extends to the top of the housing 1 and is slidably connected to the housing 1.

[0050] After sorting, the vertical bar 602 can be held and slid up and down, and the scraper 601 will slide against the surface of the breathable mesh 105 to clean the surface of the breathable mesh 105.

[0051] like Figure 1 As shown, in a preferred embodiment, based on the above method, a pull block is further fixed to the top of the vertical rod 602, and a return spring is provided between the bottom of the pull block and the housing 1.

[0052] By utilizing a return spring, the scraper 601 can be automatically reset after the vertical rod 602 is lifted and released, making it more convenient to use.

[0053] Example 3

[0054] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0055] The granular material from the broken circuit board is fed into the hopper 101 and falls onto the screening screen 3 inside the mounting frame 2. The first motor 401 is started, driving the turntable 402 to rotate. During rotation, the turntable 402 pulls and pushes the pull rod 403, thereby controlling the reciprocating sliding of the mounting frame 2 to filter the material. Simultaneously, the blower 102 starts. Because the screened material particles are small, the blower 102 operates at low power to separate copper powder and plastic powder. After screening, the larger particles remain in the screening area. At the top of the screen plate 3, the second motor 502 is started to control the screw 503 to rotate. The rotation of the screw 503 drives the fixed block 504 to move along the length of the screw 503, thereby pulling the screen plate 3 horizontally out. When the screen plate 3 is pulled out horizontally, the large particles at the top are blocked by the side of the screen plate 3 and fall downward. At this time, the power of the blower 102 is increased to sort the large particles. After the sorting is completed, the vertical bar 602 can be held and slid up and down. The scraper 601 will slide against the surface of the breathable mesh 105 to clean the surface of the breathable mesh 105.

[0056] The above merely illustrates the further embodiments of the present application, but the protection scope of the present application is not limited thereto, any skilled in the art can make equivalent substitutions or changes according to the technical scheme and concept of the present application within the disclosed scope, which all belong to the protection scope of the present application.
