[0033] Referring to Figure 1 , Figure 2 and Figure 5The vibration mechanism 2 comprises two support rings 201, the adjacent sides of the two support rings 201 are fixedly connected with the front and rear sides of the left end of the outer wall of the conveying pipe 1 respectively, and provide support for one end of the rotating rod 203, so that the rotating rod 203 can stably rotate at the end. The right end of the outer wall of the conveying pipe 1 is fixedly connected with a support block 202 on the front and rear sides, and the support block 202 cooperates with the support ring 201 to support the rotating rod 203 from the other end. The inner walls of the two support rings 201 are both rotatably connected with the rotating rod 203, and the rotating rod 203 can freely rotate around its own axis under the support of the support ring 201 and the support block 202. The right ends of the two rotating rods 203 are rotatably connected with the corresponding support blocks 202 respectively, further stabilizing the rotating structure of the rotating rod 203. The outer walls of the two rotating rods 203 are both fixedly connected with a plurality of cams 204. When the rotating rod 203 rotates, the cam 204 rotates synchronously, and the irregular contour of the cam 204 strikes the outer wall of the conveying pipe 1 to generate vibration, preventing the broken material from adhering to the inner wall of the conveying pipe 1. The outer wall of the left side of the spiral blade 3 is fixedly connected with a large gear 205, and the large gear 205 rotates with the rotation of the spiral blade 3 to transmit power to the vibration mechanism 2. The left ends of the two rotating rods 203 are both fixedly connected with a small gear 206, and the small gear 206 cooperates with the large gear 205 to receive the power transmitted by the large gear 205. The two small gears 206 are both meshingly connected with the large gear 205, and the rotating power of the spiral blade 3 is transmitted to the rotating rod 203 through gear meshing, so that the rotating rod 203 rotates and drives the cam 204 to operate, realizing the vibration function.

[0034] Specifically, when the spiral blade 3 starts to rotate under the drive of the motor 16, the large gear 205 fixed on the left side of the outer wall of the spiral blade 3 rotates, and since the small gears 206 at the left ends of the two rotating rods 203 are all in meshing connection with the large gear 205, the rotation of the large gear 205 drives the two small gears 206 to rotate, and the two rotating rods 203 are rotatably connected to the left and right ends of the conveying pipe 1 through the support rings 201 and the support blocks 202, and the rotation of the small gears 206 further drives the rotating rods 203 to rotate around their own axes. With the rotation of the rotating rods 203, the cams 204 also rotate synchronously, and during the rotation of the cams 204, the irregular profile of the cams 204 will constantly hit the outer wall of the conveying pipe 1, causing the conveying pipe 1 to vibrate. The vibration prevents the shredded materials of the waste lithium batteries from adhering in the conveying pipe 1, making the materials more smooth in the conveying process and improving the conveying efficiency. The equal spacing between adjacent cams 204 ensures the regularity and stability of the vibration, and the smooth surface of the cams 204 reduces friction loss and prolongs the service life of the equipment, ensuring the long-term stable operation of the vibration mechanism 2 and the efficient conveying of the materials.

[0035] With reference to Figure 1 , Figure 3 and Figure 4 , the top of the conveying pipe 1 is provided with a transparent cover 18, which can protect the inside of the conveying pipe 1 and facilitate the observation of the conveying situation of the materials in the pipe by the operator. Screws 19 are threadedly connected to the four corners of the transparent cover 18, and the bottom ends of the plurality of screws 19 are threadedly connected to the conveying pipe 1, so that the transparent cover 18 can be stably installed on the top of the conveying pipe 1. A plurality of positioning plates 20 are fixedly connected to the left and right sides of the bottom of the conveying pipe 1, which are used to assist in connecting and positioning the conveying pipe 1 with the external support structure. Bolts 21 are threadedly connected to the top of the outer wall of the plurality of positioning plates 20.

[0036] Specifically, the transparent cover 18 is convenient for the operator to observe the conveying situation of the materials inside due to its transparent property, and the positioning plates 20 are connected to other support structures through the bolts 21, so as to ensure that the conveying pipe 1 will not shake or displace during the conveying of the materials.

[0037] With reference to Figure 1 , Figure 2 and Figure 4 , a handle 22 is fixedly connected to the front side of the outer wall of the filtering frame 7, which provides a convenient holding position for the operator. The surface of the handle 22 is treated to prevent slipping, effectively increasing the friction between the hand and the handle 22, so that the operator's hand is not easy to slip off the handle 22 when pulling the filtering frame 7. An installation box 23 is fixedly connected to the top of the front side of the outer wall of the feeding bin 4, which provides a mounting space for the alarm 24. The inner wall of the installation box 23 is fixedly connected with the alarm 24. When an abnormal situation occurs in the feeding bin 4, an alarm signal is sent to remind the operator to pay attention and handle it in time.

[0038] Specifically, the handle 22 on the front side of the outer wall of the filter frame 7 is treated with anti-slip, which is convenient for the operator to hold, when the filter frame 7 needs to be cleaned, the filter frame 7 is easily pulled out along the sliding groove 6 through the handle 22, and the anti-slip design ensures that the hand is not easy to slip off during operation, increasing the safety and convenience of use, when an abnormality occurs in the feed bin 4, the alarm 24 issues an alarm to remind the operator to handle it in time, ensuring the normal operation of the conveyor.

[0039] Working principle: the motor 16 operates to drive the helical blade 3 connected to the output end to rotate in the inner wall of the conveying pipe 1, the shredded waste lithium battery material enters the conveying pipe 1 from the feed bin 4, and the filter frame 7 plays a role when falling to intercept large impurities, and the qualified material passes through and falls to the helical blade 3, the helical blade 3 continuously rotates, and the material is pushed along the inner wall of the conveying pipe 1 to the right by the helical thrust and the friction with the inner wall of the conveying pipe 1, and is stably forwarded to the discharge port 17, and finally is discharged from the right side of the discharge port 17 at the bottom of the conveying pipe 1, completing the conveying, when the filter frame 7 needs to be cleaned, the operator manually pulls the plug rod 9 to the right, overcomes the elastic force of the spring 13, and makes the left end of the plug rod 9 disengage from the plug slot 14 on the right side of the filter frame 7, then easily takes out the filter frame 7 from the reserved opening 5 along the sliding groove 6 for cleaning, after cleaning, the filter frame 7 is slid back to the original position along the sliding groove 6, the plug rod 9 is released, and the left end of the plug rod 9 is engaged in the plug slot 14 again under the action of the spring 13, the filter frame 7 is fixed again, and the equipment can continue to operate normally, ensuring the continuous filtering and smooth conveying of the material during the conveying process;

[0040] And by rotating the helical blade 3 under the drive of the motor 16, the large gear 205 fixed on the left side of the outer wall thereof rotates synchronously, because the small gear 206 on the left end of the two rotating rods 203 is closely engaged with the large gear 205, the rotation of the large gear 205 drives the two small gears 206 to rotate, the two rotating rods 203 are rotatably connected to the left and right ends of the conveying pipe 1 by the support ring 201 and the support block 202, respectively, and the rotation of the small gear 206 in turn causes the rotating rod 203 to rotate around its own axis, when the rotating rod 203 rotates, the cam 204 also rotates synchronously, during the rotation of the cam 204, because it has an irregular contour, it will continuously hit the outer wall of the conveying pipe 1, thereby causing the conveying pipe 1 to vibrate, which can effectively prevent the shredded waste lithium battery material from adhering in the conveying pipe 1, and ensure that the material is more smooth during the conveying process, thereby improving the conveying efficiency.

[0041] Finally, it should be noted that: the above only describes the preferred embodiments of the present application, and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for some of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
