[0016] S1: When recycling metal waste, first start the motor, and when the motor starts, drive the first rotating shaft to rotate, and the rotation of the first rotating shaft drives the fan blade to rotate, so that the external gas flows to one side of the filter;

[0017] S2: Then pour the metal waste into the feed port, and when the metal waste is put into the feed port, it contacts with the buffer plate and is buffered by the buffer plate;

[0018] S3: The rotation of the first rotating shaft drives the reciprocating screw to rotate through the pulley group, the rotation of the reciprocating screw drives the first moving block to move back and forth, the movement of the first moving block drives the movement of the rack plate, the movement of the rack plate drives the rotation of the gear, the rotation of the gear drives the rotation of the second rotating shaft, the rotation of the second rotating shaft drives the rotation of the buffer plate, so that the buffer plate rotates at a certain angle to beat the metal waste, which helps the gas to blow the non-metallic substances in the metal waste into the first recovery chamber for collection, and the heavier metal substances fall downward to the top of the screen plate;

[0019] S4: The rotation of the reciprocating screw drives the rotation of the first bevel gear, the rotation of the first bevel gear drives the rotation of the second bevel gear, the rotation of the second bevel gear drives the rotation of the third rotating shaft, the rotation of the third rotating shaft drives the rotation of the cam, the rotation of the cam drives the movement of the second moving block, and the second moving block is reciprocated by the elastic cooperation of the first spring, the movement of the second moving block drives the movement of the slider, the movement of the slider drives the movement of the screen plate, and the screen plate reciprocates to screen the metal waste at the top, the smaller materials in this part fall into the second recovery chamber for collection, and the other part of the larger materials falls into the third recovery chamber for collection.

[0020] The beneficial effects of the present invention are as follows:

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 7 As shown, in an embodiment of the present invention, an environmentally friendly metal waste automatic classification and recycling device includes a device body 1, a feed port 2 is provided at the top of the device body 1, a classification component is provided inside the device body 1, and a buffer component is provided inside the feed port 2;

[0034] Among them, the classification component includes a motor 3 arranged inside the device body 1, a first rotating shaft 4 is installed at one end of the motor 3, a fan blade 5 is fixedly installed at the end of the first rotating shaft 4 away from the motor 3, a filter screen 6 is arranged on one side of the fan blade 5, and the filter screen 6 is fixedly installed inside the device body 1.

[0035] Through the arrangement of the classification component, when recycling the metal waste, the motor 3 is first started, and when the motor 3 is started, the first rotating shaft 4 is driven to rotate, and the rotation of the first rotating shaft 4 drives the fan blade 5 to rotate, so that the external air flows to one side of the filter screen 6;

[0036] The metal waste is then poured into the feed port 2, and the non-metallic substances in the metal waste are blown into the first recovery chamber 7 by gas for collection, while the heavier metal substances fall downward to the top of the sieve plate 10, and the smaller substances in this part fall into the second recovery chamber 8 for collection, and the other larger substances fall into the third recovery chamber 9 for collection. Different substances are classified and collected by the first recovery chamber 7, the second recovery chamber 8 and the third recovery chamber 9, thereby improving the classification effect and recycling rate of the metal waste.

[0040] Through the setting of the rotating assembly, when recycling metal waste, the rotation of the first rotating shaft 4 drives the reciprocating screw 17 to rotate through the pulley group 18, the rotation of the reciprocating screw 17 drives the first moving block 16 to move back and forth, the movement of the first moving block 16 drives the movement of the rack plate 15, the movement of the rack plate 15 drives the rotation of the gear 14, the rotation of the gear 14 drives the rotation of the second rotating shaft 13, the rotation of the second rotating shaft 13 drives the rotation of the buffer plate 12, so that the buffer plate 12 rotates to a certain angle to beat the metal waste, which helps non-metallic waste (such as dust, plastic, paper scraps, etc.) to fall off from the surface or gaps of the metal waste, thereby enhancing the airflow blowing effect on the non-metallic waste, facilitating complete separation.

[0041] like Figure 4 As shown, the two rack plates 15 are symmetrically arranged.

[0042] The two groups of buffer plates 12 are rotated intermittently and alternately.

[0043] like Figures 1 to 7 As shown, the screening assembly includes a slider 25 fixedly mounted on one side of the screen plate 10, a second moving block 23 is mounted on the outer wall of the slider 25, a first spring 24 is provided on one side of the second moving block 23, a cam 22 is provided on the other side of the second moving block 23, a third rotating shaft 21 is fixedly mounted on the top of the cam 22, a second bevel gear 20 is fixedly connected to the top of the third rotating shaft 21, a first bevel gear 19 is meshedly connected to the top of the second bevel gear 20, and the first bevel gear 19 is fixedly mounted on one end of the reciprocating screw 17.

[0045] like Figure 5 As shown, the slider 25 is slidably installed inside the second moving block 23.

[0046] The sieve plate 10 is arranged to be inclined. When the sieve plate 10 moves, the slider 25 slides up and down a little inside the second moving block 23 to ensure the stability of the sieve plate 10 when it moves obliquely.

[0047] like Figure 5 As shown, a baffle plate 26 is fixedly mounted on one side of the screen plate 10 , and the baffle plate 26 is arranged on one side of the second moving block 23 .
