[0026] As Figures 1 to 4 shown, an environmental protection recycling crushing and separating device for waste electronic components includes a crusher main body 2. The crusher main body 2 includes a feed hopper 201. A base 1 is installed on the lower surface of the crusher main body 2. A pretreatment mechanism 3 for driving the waste electronic components to move to the upper end of the feed hopper 201 is provided on the upper surface of the base 1. A fixing mechanism 7 and a positioning mechanism 5 are arranged inside the pretreatment mechanism 3. A limiting mechanism 4 is installed on the front surface of the pretreatment mechanism 3; specifically, by starting the pretreatment mechanism 3 to pre-crush and compress the electronic components placed inside the pretreatment mechanism 3, the volume of the electronic components before entering the feed hopper 201 is reduced, so as to avoid blockage inside the feed hopper 201 caused by the subsequent inability of the electronic components to enter the crusher main body 2 along the feed hopper 201 as much as possible; by driving the electronic components into the feed hopper 201 through the pretreatment mechanism 3, the labor consumption of subsequent workers when putting the electronic components into the feed hopper 201 is reduced, and thus the practicability of the device is improved.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the pretreatment mechanism 3 includes a protective cover 305 and a side plate 301, the side plate 301 is installed on the upper surface of the base 1, the protective cover 305 is installed on the upper surface of the feed hopper 201, a U-shaped connecting plate 307 is installed on the upper surface of the protective cover 305, a hydraulic cylinder 308 is installed on the top of the inner wall of the U-shaped connecting plate 307, a through hole is opened on the upper surface of the protective cover 305, an output end of the hydraulic cylinder 308 is passed through the internal through hole of the protective cover 305 and an extrusion plate 311 is installed, a plurality of groups of crushing knives 312 are arranged on the lower surface of the extrusion plate 311, a positioning slot is opened on the upper surface of the protective cover 305, and the positioning slot of the protective cover 305 slides inside A limit plate 306 is connected, a motor 302 is arranged on the upper surface of the side plate 301, a slot is provided on one side of the side plate 301 close to the base 1, through holes are provided at the bottom and top of the inner wall of the slot of the side plate 301, screws 310 are rotatably connected inside the two groups of through holes of the side plate 301, the output shaft of the motor 302 is mounted on the upper surface of the screw 310, the external thread of the screw 310 is connected to the fixing plate 303, a slide bar 309 is provided on the upper surface of the fixing plate 303, the outer surface of the slide bar 309 is slidably connected to the L-shaped fixing plate 304, and the front and rear sides of the L-shaped fixing plate 304 are respectively kept parallel to the front and rear inner walls of the protective cover 305;

[0028] Specifically, the motor 302 is started to move the lower surface of the L-shaped fixing plate 304 to a position parallel to the upper surface of the feed hopper 201, and then the L-shaped fixing plate 304 and the electronic components placed on the bottom of the inner wall of the L-shaped fixing plate 304 are moved to the inside of the protective cover 305 by pushing the L-shaped fixing plate 304, and the extrusion plate 311 and the crushing knife 312 are pushed by starting the hydraulic cylinder 308 to pre-crush the electronic components, so as to prevent the subsequent electronic components from being unable to enter the inner part of the crusher body 2 along the feed hopper 201 as much as possible. The pre-processing mechanism 3 drives the electronic components to move to the upper end of the feed port of the crusher body 2, and then pushes the limit plate 306 to abut against the bottom of the inner wall of the L-shaped fixing plate 304, so that when the subsequent staff pulls the L-shaped fixing plate 304 to reset, the electronic components are blocked by the limit plate 306 and fall into the feed hopper 201, thereby reducing the labor consumed by the subsequent staff when putting the electronic components into the feed hopper 201, thereby improving the practicability of the device.

[0029] like Figure 4As shown, the fixing mechanism 7 includes a fixing rod 701. The fixing rod 701 is installed on the side of the limiting plate 306 close to the side plate 301. A magnetic block 702 is installed on the upper surface of the fixing rod 701, and the upper surface of the magnetic block 702 is adsorbed on the top of the inner wall of the protective cover 305. Specifically, by pulling the limiting plate 306 to drive the fixing rod 701 and the magnetic block 702 to move, the upper surface of the magnetic block 702 is adsorbed on the top of the inner wall of the protective cover 305, so that the subsequent fixing mechanism 7 positions the limiting plate 306 inside the positioning slot of the protective cover 305, thereby minimizing the movement of the limiting plate 306 during the subsequent process of the operator pushing the L-shaped fixing plate 304 into the protective cover 305, which may otherwise block the entry of the L-shaped fixing plate 304 into the protective cover 305.

[0030] As Figures 1 to 3 shown, the positioning mechanism 5 includes two sets of fixed sleeves 501. Two slots are opened at the bottom of the inner wall of the L-shaped fixing plate 304. The two sets of fixed sleeves 501 are both slidably connected inside the slots of the L-shaped fixing plate 304. Electric telescopic rods 502 are provided at the top of the inner walls of the two sets of fixed sleeves 501, and the output ends of the two sets of electric telescopic rods 502 are respectively installed at the bottom of the inner walls of the two grooves of the L-shaped fixing plate 304. Specifically, by starting the two sets of electric telescopic rods 502 to push the two sets of fixed sleeves 501 to move upward, the height of the upper surfaces of the two sets of fixed sleeves 501 is higher than the height of the bottom of the inner wall of the L-shaped fixing plate 304, so that the two sets of fixed sleeves 501 limit the position of the electronic components placed on the bottom of the inner wall of the L-shaped fixing plate 304 during forward and backward movement, thereby minimizing the risk of the electronic components falling along the front and rear sides of the bottom of the inner wall of the L-shaped fixing plate 304 during the subsequent up and down movement of the L-shaped fixing plate 304, which may otherwise hit the lower operators, thus improving the safety of the pretreatment mechanism 3 during use.

[0031] As Figure 1 and Figure 2 shown, a slot is opened on the front surface of the protective cover 305, and a viewing window 6 is provided inside the slot of the protective cover 305. Specifically, since the viewing window 6 is made of a transparent material, subsequent operators can view the pre-compression and segmentation effect of the electronic components inside the protective cover 305 through the viewing window 6, so that subsequent operators do not need to repeatedly pull the L-shaped fixing plate 304 for viewing, thus shortening the time consumed by subsequent operators when using the pretreatment mechanism 3 to pre-compress and segment the electronic components, and therefore improving the practicality of the device.

[0032] As Figure 1 and Figure 2As shown in the figure, the limiting mechanism 4 includes a connecting sleeve 402. The connecting sleeve 402 is installed on the front surface of the fixed plate 303. A clamping groove is formed on the front surface of the connecting sleeve 402. A U-shaped plug 401 is slidably connected inside the clamping groove of the connecting sleeve 402. A groove is formed on the front surface of the L-shaped fixed plate 304. The position of the groove of the L-shaped fixed plate 304 is on the moving path of the U-shaped plug 401. Specifically, by pushing the U-shaped plug 401, the U-shaped plug 401 is inserted into the groove of the L-shaped fixed plate 304, so that the limiting mechanism 4 restricts the movement position of the L-shaped fixed plate 304 at the upper end of the fixed plate 303, thereby minimizing the movement of the L-shaped fixed plate 304 during the subsequent upward movement of the fixed plate 303, and thus improving the stability of the L-shaped fixed plate 304 during use.

[0033] In summary: By starting the motor 302, the lower surface of the L-shaped fixed plate 304 is moved to a position parallel to the upper surface of the feed hopper 201. Then, by pushing the L-shaped fixed plate 304, the L-shaped fixed plate 304 and the electronic components placed at the bottom of the inner wall of the L-shaped fixed plate 304 are moved into the protective cover 305. By starting the hydraulic cylinder 308, the pressing plate 311 and the crushing knife 312 are pushed to pre-crush the electronic components, thereby minimizing the subsequent situation where the electronic components cannot enter the interior of the crusher main body 2 along the feed hopper 201. Driven by the pretreatment mechanism 3, the electronic components are moved to the upper end of the feed inlet of the crusher main body 2. Then, by pushing the limiting plate 306, the limiting plate 306 is abutted against the bottom of the inner wall of the L-shaped fixed plate 304, so that during the subsequent process of the operator pulling the L-shaped fixed plate 304 to reset, the electronic components are blocked by the limiting plate 306 and fall into the interior of the feed hopper 201.

[0034] Meanwhile, by pulling the limiting plate 306, the fixing rod 701 and the magnetic block 702 are driven to move, and the upper surface of the magnetic block 702 is adsorbed on the top of the inner wall of the protective cover 305, so that the subsequent fixing mechanism 7 positions the limiting plate 306 inside the positioning clamping groove of the protective cover 305, thereby minimizing the movement of the limiting plate 306 during the subsequent process of the operator pushing the L-shaped fixed plate 304 into the protective cover 305, which may block the entry of the L-shaped fixed plate 304 into the protective cover 305. By starting two groups of electric telescopic rods 502 to push two groups of fixed sleeves 501 to move upward, the height of the upper surfaces of the two groups of fixed sleeves 501 is higher than the height of the bottom of the inner wall of the L-shaped fixed plate 304, so that the two groups of fixed sleeves 501 restrict the front-back movement position of the electronic components placed at the bottom of the inner wall of the L-shaped fixed plate 304.
