[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1 - Figure 5This embodiment of a vibrating sieve for extracting copper powder from waste circuit boards includes a screening barrel 1, a screening frame 5, and a vibrating assembly. The vibrating assembly is disposed outside the screening barrel 1, and the screening frame 5 is disposed inside the screening barrel 1. The vibrating assembly includes four cams 15. A mounting cover 6 is fixedly installed on the side wall of the screening barrel 1, and a brake motor is fixedly installed on the side wall of the mounting cover 6. A first gear 7 is fixedly sleeved on the output shaft of the brake motor. A transmission rod 8 is rotatably connected to the inner wall of the mounting cover 6. A second gear 9 is fixedly sleeved on the middle section side wall of the transmission rod 8. The first gear 7 and the second gear 9 are meshed. A third gear 10 is fixedly sleeved on both ends of the transmission rod 8. A third gear 10 is fixedly connected to both sides of the screening barrel 1. Support plate 14, two support plates 14 are rotatably connected to the inner wall of mounting cover 6 by a first driven rod 12 and a second driven rod 13 respectively. A fourth gear 11 is fixedly sleeved on one end of the first driven rod 12 and the second driven rod 13 located inside the mounting cover 6. Two third gears 10 are respectively meshed with two fourth gears 11. Four cams 15 are respectively fixedly sleeved on two second driven rods 13. Four plate holes 17 are opened on the side wall of screening barrel 1. Four side plates 16 are fixedly installed on the side wall of screening frame 5. The four side plates 16 are respectively located in the four plate holes 17. The four cams 15 are respectively located below the four side plates 16. The four side plates 16 correspond to the four plate holes 17 respectively.

[0025] When in use, the brake motor drives the first gear 7 to rotate through the output shaft. The first gear 7 meshes with the second gear 9 to rotate the transmission rod 8. At this time, the third gear 10 at both ends of the transmission rod 8 meshes with the two fourth gears 11 respectively, thereby causing the first driven rod 12 and the second driven rod 13 to rotate on both sides of the screening barrel 1. The four cams 15 on the first driven rod 12 and the second driven rod 13 have different orientations. The front ends of the two cams 15 on the first driven rod 12 are set to face up and down, and the front ends of the two cams 15 on the second driven rod 13 are set to face left and right. That is, only one cam 15 will strike the side plate 16 at the same time, causing the screening frame 5 to rise. After the first driven rod 12 and the second driven rod 13 have rotated one revolution, the four cams 15 have completed one round of striking the four side plates 16. At this time, the screening frame 5 is raised in all four directions in the screening barrel 1 due to the contact between the cams 15 and the side plates 16, thereby realizing multi-directional vibration of the material in the screening frame 5 and improving the screening effect of the material in the screening frame 5.

[0026] Among them, the inner walls of the four plate holes 17 are provided with reset grooves, and reset springs are fixedly installed in the four reset grooves. The upper ends of the four reset springs are fixedly connected to spring plates 18.

[0027] By opening a reset groove and setting a reset spring and spring plate 18, after the cam 15 lifts the side plate 16, the reset spring and spring plate 18 can buffer the side plate 16 as it falls into the plate hole 17, preventing the side plate 16 from falling and making hard contact with the plate hole 17, thus avoiding damage to the side plate 16.

[0028] Among them, each of the four side plates 16 is provided with multiple anti-loosening bolts, and each of the four side plates 16 is fixedly connected to the side wall of the screening frame 5 by two anti-loosening bolts.

[0029] By setting anti-loosening bolts 16, the connection between the side plate 16 and the screening frame 5 can be effectively prevented from loosening under long-term vibration of the screening frame 5.

[0030] Among them, the upper end of the screening barrel 1 is provided with a barrel cover 2, the center of the barrel cover 2 is provided with a feed inlet 3, the feed hopper 4 is slidably inserted into the feed inlet 3, the inner wall of the screening barrel 1 is fixedly installed with a ring plate, and the lower end of the screening frame 5 overlaps the ring plate.

[0031] By setting up a ring plate, the screening frame 5 can be placed inside the screening barrel 1 by overlapping its lower end with the upper surface of the ring plate.

[0032] Among them, the lower end of the screening barrel 1 is fixedly connected with three support legs 19, the lower end of the screening barrel 1 is provided with a discharge port, and an electromagnetic valve is installed in the discharge port. The lower end of the inner wall of the screening barrel 1 is a conical inclined surface, and the lowest point of the conical inclined surface is connected to the discharge port.

[0033] By making the lower end of the inner wall of the screening barrel 1 a conical inclined surface, the screened copper powder can slide down the inclined surface to the discharge port, thus avoiding the accumulation of undischarged copper powder on the inner wall of the screening barrel 1.

[0034] Among them, the lower ends of the three support legs 19 are all provided with shock-absorbing layers, which are 5mm thick rubber pads. Bearings are embedded in the center of the two support plates 14. The first driven rod 12 and the second driven rod 13 are rotatably connected to the inner wall of the support plate 14 through the two bearings respectively.

[0035] By setting a shock-absorbing layer, the impact of vibration generated inside the screening barrel 1 during operation on the three support legs 19 can be effectively reduced, thereby improving the overall stability of the device. The bearing setting helps to reduce the rotational friction between the first driven rod 12 and the second driven rod 13 in the support plate 14, thus extending their service life.

[0036] The lower end face of the screening frame 5 is provided with multiple electric heating elements, which are all arranged between the screen holes on the bottom end face of the screening frame 5. A controller is provided outside the screening barrel 1, and the controller is electrically connected to the brake motor, the solenoid valve and the multiple electric heating elements respectively.

[0037] By setting up electric heating elements and a controller, the electric heating elements can heat the materials inside the screening frame 5. They can be used to heat damp copper powder mixtures at low temperatures to prevent damp materials from clumping and reducing screening efficiency. The controller can remotely control multiple electric heating elements, brake motors, and solenoid valves, making it more intelligent.

[0038] The working principle of the above embodiment is as follows: During use, the brake motor drives the first gear 7 to rotate through the output shaft. The first gear 7 meshes with the second gear 9 to rotate the transmission rod 8. At this time, the third gear 10 at both ends of the transmission rod 8 meshes with the two fourth gears 11 respectively, thereby causing the first driven rod 12 and the second driven rod 13 to rotate on both sides of the screening barrel 1. The first driven rod 12 and the second driven rod 13 will drive the four cams 15 to continuously strike the four side plates 16 connected to the screening frame 5. The front end of the cam 15 contacts and lifts the side plate 16 in the plate hole 17. The screening frame 5 in the screening barrel 1 will be lifted on one side due to the side plate 16 being lifted. After the four side plates 16 are continuously struck and lifted, the screening frame 5 in the screening barrel 1 is lifted in all four directions due to the contact between the cams 15 and the side plates 16, thereby realizing multi-directional vibration of the material in the screening frame 5 and improving the screening effect of the material in the screening frame 5.

[0039] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
