DETAILED DESCRIPTION

[0021] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0022] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2 , Figure 5 As shown, it is a structural diagram of a rare earth waste recycling device in the mechanical field provided by an embodiment of the present invention, including a recycling box 1, the bottom wall of the recycling box 1 is fixedly installed with support legs 11 respectively, and the two sides of the recycling box 1 are respectively provided with a feeding funnel 12, and the bottom wall of the recycling box 1 is provided with a guide outlet 13, and a sealing plate 131 is rotatably installed in the guide outlet 13, and the bottom wall of the recycling box 1 is provided with a locking piece 8 that cooperates with the sealing plate 131, and a bearing column 2 is rotatably installed in the inner cavity of the recycling box 1, and one end of the bearing column 2 extends to the outside of the recycling box 1, and a screening plate 3 is fixedly installed on the surface of the bearing column 2, and the surface of the screening plate 3 is provided with evenly distributed meshes, and a crushing mechanism 4 is provided on the surface of the bearing column 2, and the crushing mechanism 4 includes There are an extrusion roller 41 and a positioning component 42, the positioning component 42 is located on the surface of the supporting column 2 and is connected to the extrusion roller 41, the positioning component 42 is used to support and position the extrusion roller 41 above the supporting column 2, the side wall of the recycling box 1 is provided with a control mechanism 5 that cooperates with the supporting column 2, the control mechanism 5 includes a swing component 51 and a flip component 52, the swing component 51 is located on the side wall of the recycling box 1 and is connected to the supporting column 2, the swing component 51 is used to control the supporting column 2 to reciprocate a certain angle in the inner cavity of the recycling box 1, the flip component 52 is connected to the swing component 51, and the flip component 52 controls the supporting column 2 and the screen plate 3 to rotate one hundred and eighty degrees in the inner cavity of the recycling box 1 by cooperating with the swing component 51.

[0024] Initially, the screen plate 3 remains horizontal in the inner cavity of the recycling box 1, and the positioning component 42 controls the extrusion roller 41 to be directly above the screen plate 3. The rare earth waste that needs to be screened after crushing is fed into the inner cavity of the recycling box 1 through the feeding funnel 12, and the rare earth waste falls onto the surface of the screen plate 3. The swing component 51 controls the supporting column 2 to reciprocate in the inner cavity of the recycling box 1, and the supporting column 2 drives the screen plate 3 to reciprocate synchronously at a certain angle in the inner cavity of the recycling box 1. When the screen plate 3 swings back and forth, it can drive the rare earth waste on the surface of the screen plate 3 to roll synchronously, and particles of appropriate size pass through the mesh on the surface of the screen plate 3 and fall to the bottom of the recycling box 1. At this time, the discharge port 13 is in an open state, and the waste particles screened at the bottom of the recycling box 1 pass through the discharge port 13 and fall to the outside of the recycling box 1. The screening plate 3 continues to swing, and the larger rare earth particles fall on the surface of the screening plate 3. After the preliminary screening is completed, the locking member 8 fixes the sealing plate 131 in the guide port 13. At this time, the guide port 13 is in a closed state, and the flip assembly 52 cooperates with the swing assembly 51 to control the bearing column 2 and the screening plate 3 to rotate 180 degrees in the inner cavity of the recycling box 1. At this time, the larger rare earth particles on the surface of the screening plate 3 fall to the bottom of the recycling box 1. At this time, the positioning assembly 42 controls the squeezing roller 41 to be directly below the screening plate 3, and the swing assembly 51 controls the bearing column 2 and the screening plate 3 to swing back and forth in a small amplitude again. The positioning components 42 cooperate with each other to control the squeezing roller 41 to roll back and forth at the bottom of the recycling box 1. The squeezing roller 41 can crush the larger rare earth particles at the bottom of the recycling box 1. After crushing, the flipping component 52 cooperates with the swinging component 51 to control the supporting column 2 and the screen plate 3 to rotate one hundred and eighty degrees again. At this time, the squeezing roller 41 moves again to the top of the screen plate 3. When rotating, the screen plate 3 shovels the crushed rare earth particles at the bottom of the recycling box 1 onto the surface of the screen plate 3. The swinging component 51 controls the supporting column 3 and the screen plate 3 to swing back and forth, so that the rare earth particles can be screened and filtered again.

[0025] like Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, as a preferred embodiment of the present invention, the positioning assembly 42 includes two groups of relatively distributed side plates 421 fixedly installed on the surface of the supporting column 2, and the two groups of side plates 421 are rotatably installed with a rotating column 422 at one end away from the supporting column 2, and the extrusion roller 41 is fixedly installed on the surface of the rotating column 422. The surface of the side plate 421 is provided with a buffer portion 6 connected to the rotating column 422, and the buffer portion 6 is used to adjust the relative position of the rotating column 422 and the side plate 421.

[0026] The two sets of side plates 421 support and position the rotating column 422 and the squeezing roller 41. Initially, the squeezing roller 41 is above the screening plate 3. When the bearing column 2 swings back and forth, the squeezing roller 41 rotates synchronously above the screening plate 3. The squeezing roller 41 does not interfere with the screening process of the rare earth particles. When it is necessary to crush the large-sized rare earth particles left by the screening on the surface of the screening plate 3, the locking member 8 fixes the position of the sealing plate 131 in the guide port 13. At this time, the guide port 13 is in a closed state. The flip assembly 52 cooperates with the swing assembly 51 to control the bearing column 2 and the screening plate 3 to rotate 180 degrees. At this time, the squeezing roller 41 moves to the bottom of the screening plate 3 and is at the bottom of the recycling box 1. When the swing assembly 51 controls the bearing column 2 to rotate back and forth, the side plate 421 cooperates with the rotating column 422 to drive the squeezing roller 41 to roll back and forth at the bottom of the recycling box 1. The squeezing roller 41 can crush the large-sized rare earth particles.

[0027] like Figure 5 , Figure 6 As shown, as a preferred embodiment of the present invention, the buffer portion 6 includes two groups of slide grooves 61 respectively opened on the surfaces of the side plates 421, and a bearing block 62 is slidably installed in the slide groove 61. The two ends of the rotating column 522 are respectively rotatably connected to the bearing block 62, and an extrusion spring 63 is fixedly installed at one end of the slide groove 61 close to the bearing column 2, and the telescopic end of the extrusion spring 63 is connected to the bearing block 62.

[0028] When the side plate 421 drives the rotating column 422 and the squeezing roller 41 to roll at the bottom of the recycling box 1, the squeezing spring 63 applies a thrust to the supporting block 62 and then applies pressure to the squeezing roller 41 toward the bottom wall of the recycling box 1. The supporting block 62 moves in the slide groove 61 and then adjusts the position of the squeezing roller 41 to prevent the rare earth particles from getting stuck in the gap between the squeezing roller 41 and the recycling box 1 when the size is large.

[0029] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, as a preferred embodiment of the present invention, the swing assembly 51 includes a positioning plate 511 fixedly installed at one end of the supporting column 2 located on the outside of the recycling box 1, and a long guide groove 512 is provided on the surface of the positioning plate 511. A driving disk 513 is rotatably installed on the side wall of the recycling box 1, and a guide column 514 is provided on the surface of the driving disk 513 at a position deviating from the center of the circle, and the guide column 514 is inserted into the guide groove 512. A motor 515 is fixedly installed on the side wall of the recycling box 1 through a bracket, and a transmission gear disk 516 is fixedly installed on the output shaft of the motor 515, and a gear ring 517 meshing with the transmission gear disk 516 is fixedly installed on the annular side wall of the driving disk 513.

[0030] When in use, the motor 515 drives the transmission gear plate 516 to rotate, and the transmission gear plate 516 engages with the gear ring 517 for transmission, which can drive the driving disk 513 to rotate, and the driving disk 513 drives the guide column 514 to rotate synchronously. When rotating, the guide column 514 cooperates with the guide groove 512, and can drive the positioning plate 511 to swing back and forth at a certain angle. When swinging, the positioning plate 511 drives the supporting column 2 and the screening plate 3 to rotate synchronously back and forth in the inner cavity of the recovery box 1.

[0031] like Figure 1 , Figure 3 , Figure 4 , Figure 5 As shown, as a preferred embodiment of the present invention, the flip assembly 52 includes a gear ring 522 sleeved on the surface of the bearing column 2, the gear ring 522 meshing with the gear ring 517, a telescopic cavity 523 is opened inside the bearing column 2, a first electric telescopic rod 524 is fixedly installed in the telescopic cavity 523, a sliding block 525 is fixedly installed at the telescopic end of the first electric telescopic rod 524, a plurality of connecting rods 526 are fixedly installed on the side wall of the sliding block 525, the connecting rod 526 extends to the outside of the bearing column 2 at one end away from the sliding block 525 and is fixedly connected to the gear ring 522, a storage cavity 527 is opened in the driving disk 513, a second electric telescopic rod 528 is fixedly installed in the storage cavity 527, the telescopic end of the second electric telescopic rod 528 is connected to the guide column 514, and two groups of positioning plates 511 are provided and are relatively distributed on the surface of the bearing column 2.

[0032] Initially, the gear ring 522 and the gear ring 517 are separated from each other. When it is necessary to crush the rare earth particles with larger sizes on the surface of the screen plate 3 again, the second electric telescopic rod 528 controls the guide column 514 to move toward the storage chamber 527. At this time, the guide column 514 moves to the outside of the guide groove 512, and the first electric telescopic rod 524 pulls the sliding block 525 to move in the telescopic chamber 523, thereby driving the gear ring 522 to move synchronously on the outside of the bearing column 2. After the gear ring 522 is engaged with the gear ring 517, the motor 515 drives the transmission gear disc 516 to rotate, and the transmission gear disc 516 and the gear ring 517 are engaged. The meshing transmission can drive the driving disk 513 to rotate, and the meshing transmission of the gear ring 517 and the gear ring 522 can drive the bearing column 2 to rotate synchronously. After the bearing column 2 and the screening plate 3 rotate 180 degrees in the inner cavity of the recycling box 1, the motor 515 stops rotating, and the first electric telescopic rod 524 pushes the sliding block 525 to move in the telescopic cavity 523, thereby separating the gear ring 522 and the gear ring 517 from each other. The second electric telescopic rod 528 pushes the guide column 514 to move toward the outside of the storage cavity 527, so that the guide column 514 is inserted into the guide groove 512 on the surface of another set of positioning plates 511. The motor 515 drives the transmission toothed disk 516 to rotate, and the transmission toothed disk 516 and the gear ring 517 mesh transmission, which can drive the driving disk 513 to rotate, and the driving disk 513 drives the guide column 514 to rotate synchronously. When the guide column 514 rotates, it cooperates with the guide groove 512 to drive the positioning plate 511 to swing back and forth again.

[0033] like Figure 2 , Figure 5 As shown, as a preferred embodiment of the present invention, guide plates 7 are respectively provided at both ends of the screen plate 3 , and the guide plates 7 are in contact with the inner wall of the recovery box 1 .

[0034] The guide sheet 7 can effectively prevent the rare earth particles from getting stuck in the gap between the screen plate 3 and the inner wall of the recovery box 1 .

[0035] like Figure 1 , Figure 2 As shown, as a preferred embodiment of the present invention, the locking member 8 includes a bottom plate 81 fixedly installed on the bottom wall of the sealing plate 131, a threaded hole 82 is opened on the surface of the recovery box 1, and a fixing bolt 83 that cooperates with the threaded hole 82 is provided on the surface of the bottom plate 81.

[0036] By the cooperation between the fixing bolts 83 and the threaded holes 82, the positions of the bottom plate 81 and the sealing plate 131 can be conveniently adjusted. During screening, the drain port 13 is in an open state. When crushing is required, the sealing plate 131 controls the drain port 13 to be in a closed state.

[0037] The working principle of the present invention is: initially, the screen plate 3 is kept in a horizontal state in the inner cavity of the recovery box 1, the squeezing roller 41 is above the screen plate 3, and the rare earth waste that needs to be screened after crushing is fed into the inner cavity of the recovery box 1 through the feeding funnel 12, and the rare earth waste falls onto the surface of the screen plate 3.

[0038] The motor 515 drives the transmission gear disc 516 to rotate, and the transmission gear disc 516 meshes with the gear ring 517 to drive the driving disc 513 to rotate, and the driving disc 513 drives the guide column 514 to rotate synchronously. The guide column 514 cooperates with the guide groove 512 when rotating, and can drive the positioning plate 511 to swing back and forth at a certain angle. When the positioning plate 511 swings, it drives the bearing column 2 and the screen plate 3 to rotate synchronously in the inner cavity of the recycling box 1. When the screen plate 3 swings back and forth, it can drive the rare earth waste on the surface of the screen plate 3 to roll synchronously, and the particles of suitable size pass through the mesh on the surface of the screen plate 3 and fall to the bottom of the recycling box 1. At this time, the guide outlet 13 is in an open state, and the waste particles screened at the bottom of the recycling box 1 pass through the guide outlet 13 and fall to the outside of the recycling box 1. The screen plate 3 continues to swing, and larger rare earth particles fall on the surface of the screen plate 3. After the initial screening is completed, and when it is necessary to crush the larger rare earth particles left on the surface of the screen plate 3, the fixing bolts 83 cooperate with the threaded holes 82 to adjust the positions of the bottom plate 81 and the sealing plate 131, and the sealing plate 131 controls the guide port 13 to be in a closed state. The second electric telescopic rod 528 controls the guide column 514 to move toward the storage chamber 527. At this time, the guide column 514 moves to the outside of the guide groove 512. The first electric telescopic rod 524 pulls the sliding block 525 to move in the telescopic chamber 523 and then drives the gear ring 522 to move synchronously on the outside of the bearing column 2. After the gear ring 522 is engaged with the gear ring 517, the motor 515 drives the transmission gear disc 516 to rotate. The transmission gear disc 516 is engaged with the gear ring 517 for transmission, which can drive the drive disc 513 to rotate. The gear ring 517 and the gear ring 517 are engaged and driven. The gear ring 522 is meshed and driven, which can drive the bearing column 2 to rotate synchronously. After the bearing column 2 and the screening plate 3 rotate 180 degrees in the inner cavity of the recycling box 1, the motor 515 stops rotating, and the first electric telescopic rod 524 pushes the sliding block 525 to move in the telescopic cavity 523, thereby separating the gear ring 522 and the gear ring 517 from each other. The second electric telescopic rod 528 pushes the guide column 514 to move toward the outside of the storage cavity 527, so that the guide column 514 is inserted into the guide groove 512 on the surface of another set of positioning plates 511. The motor 515 drives the transmission gear disc 516 to rotate, and the transmission gear disc 516 and the gear ring 517 are meshed and driven, which can drive the driving disc 513 to rotate, and the driving disc 513 drives the guide column 514 to rotate synchronously. When the guide column 514 rotates, it cooperates with the guide groove 512 to drive the positioning plate 511 to swing back and forth again. The positioning plate 511 drives the bearing column 2 to rotate back and forth, and the side plate 421 cooperates with the rotating column 422 to drive the squeezing roller 41 to roll back and forth at the bottom of the recycling box 1. The squeezing roller 41 can crush and pulverize larger rare earth particles.After crushing, the supporting column 2 and the screen plate 3 can be controlled to rotate one hundred and eighty degrees again. At this time, the extrusion roller 41 moves again to the top of the screen plate 3. When the screen plate 3 rotates, the rare earth particles crushed by the crushing at the bottom of the recovery box 1 are shoveled to the surface of the screen plate 3 again. The supporting column 3 and the screen plate 3 are controlled to swing back and forth, so that the rare earth particles can be screened and filtered again.

[0039] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
