DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] An embodiment of the electronic waste recycling device of the present application is shown in Figures 1 to 7 .

[0026] An electronic waste recycling device comprises a shell 100, a guide mechanism 200, two crushing plates 300 and two crushing belts 400.

[0027] The shell 100 is provided with a feeding port 101, and the two crushing belts 400 are rotatably installed in the shell 100 in the first direction, the first direction being horizontal, one end of each of the two crushing belts 400 being close to each other, the other end being away from each other, the close-to-each-other end of each of the two crushing belts 400 being engaged, and the away-from-each-other end of each of the two crushing belts 400 being located on the side of the close-to-each-other end close to the feeding port 101.

[0028] The guiding mechanism 200 is installed in the shell 100, and the guiding mechanism 200 defines a first dropping area 210 and a second dropping area 220 between the two crushing belts 400, the first dropping area 210 is used for receiving garbage with a size less than or equal to a first preset value to pass, the second dropping area 220 is used for receiving garbage with a size greater than the first preset value to pass, and the garbage falling in the first dropping area 210 can directly enter one end where the two crushing belts 400 engage, and the garbage falling in the second dropping area 220 moves synchronously with the rotation of the crushing belts 400. The two crushing plates 300 are each installed in the shell 100 in parallel with one of the crushing belts 400, and each of the crushing plates 300 and one of the crushing belts 400 defines a pre-crushing interval, and the pre-crushing interval is located between the second dropping area 220 and the end where the two crushing belts 400 engage. The crushing plates 300 can move relative to the crushing belts 400. The shell 100 is provided with a discharge port 102 below the two crushing belts 400, which is used for discharging the crushed garbage.

[0029] The shell 100, the guiding mechanism 200, the two crushing plates 300 and the two crushing belts 400 cooperate to achieve the following effects. After the garbage enters the shell 100 from the feeding port 101, a part of the garbage with a size less than or equal to the first preset value can enter the first dropping area 210 under the action of the guiding mechanism 200, and other garbage (including garbage with a size greater than the first preset value and garbage with a size less than or equal to the first preset value) will fall on the crushing belts 400 from the second dropping area 220. With the continuous rotation of the crushing belts 400, the garbage will continuously move to the end where the two crushing belts 400 approach each other, and pass through the crushing plates 300 in the process of movement. The garbage will be torn under the action of the relative movement between the crushing plates 300 and the crushing belts 400 when passing through the crushing plates 300, so as to achieve pre-crushing of the garbage. Then, the garbage reaches the end where the two crushing belts 400 approach each other, and is synchronously crushed with the garbage with a size less than or equal to the first preset value. Pre-crushing of the garbage with a size greater than the first preset value can increase the overall crushing efficiency and improve the crushing effect of the garbage with a size greater than the first preset value.

[0030] In the embodiment, the crushing zone 400 comprises a belt body 401, a first transmission shaft 402 and a second transmission shaft 403, the first transmission shaft 402 and the second transmission shaft 403 are arranged on the shell 100 along the first direction and can rotate around their own axes, the first transmission shaft 402 is located on the side of the second transmission shaft 403 close to the vertical central axis of the shell 100 in the second direction. The second direction is horizontal and perpendicular to the first direction, the belt body 401 is arranged around the first transmission shaft 402 and the second transmission shaft 403, and a plurality of first crushing knives 404 are uniformly distributed in the circumferential direction of the belt body 401, each crushing plate 300 is parallel to the belt body 401, and a plurality of second crushing knives 301 are arranged on the side of the crushing plate 300 close to the first crushing knife 404. When the garbage passes through the pre-crushing space, the relative movement of the first crushing knife 404 and the second crushing knife 301 can tear the garbage, realizing the pre-crushing of the garbage.

[0031] Further, the shell 100 is provided with a motor 103, the first transmission shaft 402 is arranged on the output shaft of the motor 103 through a transmission belt and rotates synchronously with the motor 103. The rotating directions of the corresponding motors 103 arranged on the two first transmission shafts 402 are opposite, so that the garbage can be crushed when entering the end of the two crushing zones 400 engaged with each other.

[0032] In the embodiment, the electronic waste recycling device further comprises a hydraulic cylinder 500 and a connecting block 501. The two ends of the second transmission shaft 403 are provided with rotating blocks 405, the rotating blocks 405 are coaxially arranged with the second transmission shaft 403 and can rotate relative to each other, the rotating blocks 405 extend out of the shell 100, the hydraulic cylinder 500 is arranged on the shell 100 and can extend and retract in the vertical direction, the connecting block 501 is fixedly arranged on the output end of the hydraulic cylinder 500, and the two rotating blocks 405 arranged on the two second transmission shafts 403 are rotatably connected to the connecting block 501 through two connecting rods respectively.

[0033] Specifically, the shell 100 is provided with a track groove 104, the second transmission shaft 403 extends out of the shell 100 through the track groove 104 and is connected to the rotating block 405. The rotating block 405 is provided with a rotating groove, the second transmission shaft 403 is rotatably arranged in the rotating groove, the second transmission shaft 403 is provided with a protrusion in the circumferential direction, and the rotating block 405 is provided with a groove capable of rotating with the protrusion, so that the rotating block 405 and the second transmission shaft 403 can move relative to each other.

[0034] The hydraulic cylinder 500 and the connecting block 501 are matched to make the two crushing belts 400 present a V-shaped pattern in the shell 100 by moving the two ends of the two crushing belts 400 close to each other and moving the other ends away from each other. When crushing, the hydraulic cylinder 500 is started to drive the connecting block 501 to move in the vertical direction. When the connecting block 501 moves, the two rotating blocks 405 are driven to rotate in the track groove 104 through the connecting rod, so that the ends of the two crushing belts 400 close to each other can rotate in the first direction, from opening to gathering and then opening again, and the cycle is repeated. The setting of the crushing belt 400 increases the breaking path of the garbage, and when the two crushing belts 400 change from opening to gathering, the activity space of the crushed garbage is reduced, so that the garbage is prevented from breaking during the crushing process.

[0035] Further, the electronic waste recycling device further comprises two rotating frames 502 rotatably installed in the shell 100 in the first direction, and the two crushing belts 400 are rotatably installed on the two rotating frames 502. Specifically, the first transmission shaft 402 and the second transmission shaft 403 corresponding to each crushing belt 400 are rotatably installed at both ends of one rotating frame 502.

[0036] In the embodiment, the guide mechanism 200 comprises a first connecting frame 230, a second connecting frame 240, two connecting plates 250 and two telescopic rods 260. The first connecting frame 230 is arranged in the vertical direction in the shell 100 and located between the two crushing belts 400. The second connecting frame 240 is slidably installed on the first connecting frame 230 in the vertical direction. The two telescopic rods 260 are slidably installed on both sides of the first connecting frame 230 in the vertical direction. The two connecting plates 250 are located on both sides of the first connecting frame 230. The connecting plates 250 are rotatably connected to the second connecting frame 240 and one telescopic rod 260 at both ends, respectively. The two rotating frames 502 are provided with a sliding groove 503 in the third direction. The third direction is the direction of the side of the crushing belt 400. The two crushing plates 300 are slidably installed in the two sliding grooves 503, and the two ends of each crushing plate 300 are rotatably connected to the first connecting frame 230 and one telescopic rod 260.

[0037] The two connecting plates 250 and the two crushing plates 300 enclose a first material falling area 210. Each crushing belt 400 and the corresponding connecting plate 250 form a second material falling area 220. The connecting plate 250 is uniformly provided with a plurality of first material falling ports 252. The first connecting frame 230 is provided with a second material falling port 231. The first material falling port 252 and the second material falling port 231 only allow garbage with a size less than or equal to a first preset value to enter. The second material falling port 231 is located directly above the end of the two crushing belts 400 close to each other, so that the garbage can directly enter the end of the two crushing belts 400 engaged.

[0038] The first and second connection frames 230 and 240, the two connecting plates 250 and the two telescopic rods 260 cooperate to define the first and second dropping areas 210 and 220 between the two crushing belts 400, so that the garbage with a size less than or equal to the first preset value can pass through the first dropping area 210, and other garbage can fall into the second dropping area 220. When the two crushing belts 400 rotate around the first direction respectively, the crushing belts 400 will drive the two crushing plates 300 to rotate, and then the telescopic rods 260 will be retracted, the second connection frame 240 will move upward relative to the first connection frame 230, and the first dropping area 210 will be gathered synchronously. At the same time, the crushing plates 300 will slide on the rotating frames 502 to realize the relative movement between the crushing plates 300 and the crushing belts 400, and the first and second crushing knives 404 and 301 will cooperate with each other to pre-crush the garbage with a size greater than the first preset value.

[0039] Further, the two connecting plates 250 are uniformly provided with a plurality of guide pieces 251. By arranging the plurality of guide pieces 251, the guide pieces 251 on the connecting plates 250 can guide the garbage in the second dropping area 220 when the first dropping area 210 enclosed by the two connecting plates 250 and the two crushing plates 300 is constantly deformed, and the resistance caused by the garbage when the two crushing belts 400 move close to each other can be reduced.

[0040] Further, the shell 100 is provided with two sealing plates 105, each rotating frame 502 abuts against one sealing plate 105, and the sealing plate 105 and the shell 100 are connected by a first elastic member 106 arranged along the second direction.

[0041] By arranging the two sealing plates 105, when the two crushing belts 400 rotate around the first direction respectively, the rotating frames 502 will be driven to rotate synchronously and move towards or away from the sealing plates 105. When the rotating frames 502 move towards the sealing plates 105, the first elastic member 106 will be compressed, and when the rotating frames 502 move away from the sealing plates 105, the first elastic member 106 will reset, so that the sealing plates 105 always abut against the rotating frames 502. This ensures that the garbage can fall into the second dropping area 220 when the two crushing belts 400 rotate around the first direction respectively.

[0044] Further, the shell 100 is provided with a stop block 107, the stop block 107 is arranged along the first direction and is located directly above the poking piece 620, and the stop block 107 and the shell 100 define two feeding ports 101.
