The space between the inner surface of the outer cylinder 11 and the outer surface of the outer cylinder 21 constitutes a feeding channel 12, and a driving component 3 for driving the filter component 2 to rotate is installed on the feeding component 1.

[0015] like Figure 5 and Figure 6 As shown, the driving assembly 3 includes a first mounting portion 31 and a second mounting portion 32. Two first adapter portions 14 are fixedly connected to the outer surface of the outer cylinder 11. A first adapter groove 311 is formed on the inner surface of the first mounting portion 31, and a second adapter groove 321 is formed on the inner surface of the second mounting portion 32. The two first adapter portions 14 are rotatably connected to the first adapter groove 311 and the second adapter groove 321 respectively. A fixing sleeve 312 is fixedly connected to the first mounting portion 31, and a dual-axis output motor 313 is installed in the fixing sleeve 312. The two output ends of the dual-axis output motor 313 are respectively fixedly connected with the second gear 3131 and the third gear 3132, the third gear ring 25 is fixedly connected to the one side surface of the first clamping member 22, and the adapter sleeve 314 is fixedly connected to the one side surface of the first mounting portion 31 close to the third gear ring 25. A limiting rotating shaft is rotatably connected inside the adapter sleeve 314, and one end of the limiting rotating shaft is fixedly connected with a fourth gear 315 that is meshed with the second gear 3131 and the third gear ring 25 at the same time. A lifting assembly 4 is installed below the driving assembly 3.

[0016] In the production and preparation process of the existing rare earth polishing powder, a ball mill is usually used to further process the rare earth materials after the pulverization. Since the particles of the pulverized rare earth materials are of different sizes, there will be a large volume difference, so the required processing time is also different. Directly feeding the materials into the ball mill for unified processing will affect the overall processing efficiency. In order to solve the above problems, the present invention is provided with a feeding component 1, a filtering component 2, a driving component 3 and a lifting component 4. When feeding, the feeding component 1 and the filtering component 2 are first placed at an angle with the help of the lifting component 4, and the outer cylinder 21 is higher than The reprocessing cylinder 24 is then started, and the dual-axis output motor 313 is started to drive the filter assembly 2 to rotate through the driving assembly 3, and then the rare earth material is sent into the outer cylinder 21. It should be explained in detail here that since the auger filter screen 23 is arranged in a spiral shape, when the filter assembly 2 rotates, the spiral auger filter screen 23 rotates in different directions according to the different rotation directions. In the present invention, when the filter assembly 2 rotates, the auger filter screen 23 rotates in a direction toward the reprocessing cylinder 24. Since the auger filter screen 23 rotates in a direction toward the reprocessing cylinder 24, for For the rare earth materials sliding down along the inner wall of the inclined outer cylinder 21 under the action of gravity, the auger filter screen 23 will make a lot of contact with the rare earth materials as the filter assembly 2 rotates. During the contact process, the rare earth materials of appropriate size enter the feeding channel 12 through the mesh holes on the auger filter screen 23, and then the feeding is completed through the feeding channel 12. The rare earth materials exceeding the mesh size will eventually slide all the way to the reprocessing cylinder 24, and the rare earth materials will be filtered and screened according to the particle size. In this process, the rotating auger filter screen 23 will hinder the rare earth materials from sliding down. Thus, the time required for the rare earth material to slide from the outer cylinder 21 to the reprocessing cylinder 24 is prolonged, the contact between the rare earth material and the auger-type filter screen 23 is increased, and the filtering and screening effect is improved. In addition, the rare earth material with inappropriate particle size will eventually gather in the reprocessing cylinder 24, and then with the rotation of the reprocessing cylinder 24, driven by the protruding column 242, the rare earth material is lifted to a high place and then falls down. In this process, the rare earth materials constantly collide with each other and break them. After being broken, the rare earth material with appropriate particle size passes through the second material filter screen 243 and enters the feeding channel 12. After the feeding work is completed, the rare earth materials that are still unqualified need to be discharged. At this time, the filter component 2 can be adjusted to an inclined state where the reprocessing cylinder 24 is higher than the outer cylinder 21 with the help of the lifting component 4, and then the dual-axis output motor 313 is started to drive the filter component 2 to rotate through the driving component 3. Under the action of gravity, the rare earth materials in the reprocessing cylinder 24 slide from the reprocessing cylinder 24 to the outer cylinder 21. In this process, the rotating auger filter screen 23 will promote the discharge of rare earth materials and save time.

[0017] like Figure 7 As shown, the lifting assembly 4 includes a first electric cylinder 41 and a second electric cylinder 42. The first mounting portion 31 and the second mounting portion 32 are both provided with connecting members 33. The output ends of the first electric cylinder 41 and the second electric cylinder 42 are respectively provided with a first connecting shaft 411 and a second connecting shaft 421. The first connecting shaft 411 and the second connecting shaft 421 are respectively rotatably connected to the connecting members 33 on the first mounting portion 31 and the second mounting portion 32. The bottom end of the first electric cylinder 41 is fixedly connected with a first bottom plate 412, the bottom end of the second electric cylinder 42 is fixedly connected with a second bottom plate 422, and a receiving assembly 5 is installed on one end of the filter assembly 2.

[0018] By controlling the length of the first electric cylinder 41 and the second electric cylinder 42 respectively, the feeding assembly 1 and the filtering assembly 2 can be adjusted to two different tilting states, corresponding to the filtering feeding of rare earth materials and the discharge of unqualified rare earth materials respectively. When feeding, the first electric cylinder 41 is long and the second electric cylinder 42 is short. When discharging unqualified rare earth materials, the first electric cylinder 41 is short and the second electric cylinder 42 is long. The switching between the two tilting states is convenient and the operation is simple.

[0019] like Figure 8 As shown, the receiving assembly 5 includes a receiving tube 51, a receiving portion 211 is installed on one end of the outer cylinder 21, a sealing ring 52 rotatably connected to the receiving portion 211 is fixedly connected to the end of the receiving tube 51 close to the outer cylinder 21, and a second adapter portion 53 is fixedly connected to the sealing ring 52, a fixing frame 316 is installed on the side surface of the first mounting portion 31 close to the receiving tube 51, a limiting groove 317 rotatably connected to the second adapter portion 53 is installed on the inner surface of the fixing frame 316, and an adjusting assembly for adjusting the angle of the receiving tube 51 is installed on the first mounting portion 31.

[0020] With the help of the receiving tube 51, the rare earth material can be more conveniently delivered into the outer cylinder 21, thereby facilitating the feeding. When discharging unqualified rare earth materials, the receiving tube 51 can be rotated 180° with the help of the adjusting component so that it faces downward, thereby facilitating the guidance and collection of the unqualified rare earth materials during the discharge process.

[0021] like Fig. 9 and Fig.10 As shown, the adjustment component includes an adjustment motor 318 installed on the surface of one side of the first installation part 31 close to the receiving tube 51, a fifth gear 319 is fixedly connected to the output end of the adjustment motor 318, a fourth gear ring 54 meshing with the fifth gear 319 is installed on the receiving tube 51, a 3181 electrically connected to the adjustment motor 318 for controlling the rotation of the adjustment motor 318 is installed on the surface of one side of the first installation part 31 close to the first electric cylinder 41, and a trigger rod 413 for triggering 3181 is installed on the top of the output end of the first electric cylinder 41.

[0022] When the present invention is switched between the two states of filtering feed and discharging unqualified materials, it is necessary to control and change the length of the first electric cylinder 41 and the second electric cylinder 42, thereby changing the tilting direction of the feeding assembly 1 and the filtering assembly 2. During the process of changing the tilting direction of the feeding assembly 1, a contact will occur between the trigger rod 413 and 3181, and the trigger rod 413 squeezes and triggers 3181, so that the adjusting motor 318 is started, and the output end of the adjusting motor 318 drives the fourth gear ring 54 to rotate through the fifth gear 319, thereby driving the receiving tube 51 to rotate 180°. According to the needs of the two different states of filtering feed and discharging unqualified materials, the direction of the receiving tube 51 is automatically adjusted to meet the working requirements.

[0023] like Figure 3 and Figure 4 As shown, a dust prevention assembly is installed between the reprocessing cylinder 24 and the second mounting portion 32, and the dust prevention assembly includes a fixing ring 244 installed on the second dust filter screen 241, one end of the fixing ring 244 is rotatably connected to a side surface of the second mounting portion 32, a sealing ring rotatably connected to the inner surface of the fixing ring 244 is installed on the second mounting portion 32, a fixing member 245 is fixedly connected to the inner surface of the fixing ring 244, a plurality of mounting holes 246 are opened on the fixing member 245, and a mounting shaft 247 is rotatably connected in each of the plurality of mounting holes 246, and a mounting shaft 247 is installed on one end of the mounting shaft 247 close to the second dust filter screen 241 The fan blades 248 and the first gear 249 are installed on the end of the mounting shaft 247 away from the second dust filter screen 241, and the first ring gear 15 meshing with the third gear 3132 is installed on the outer cylinder 11. A plurality of feeding channels 12 are symmetrically installed on the inner surface of the outer cylinder 11, and a baffle 16 is fixedly connected to the inner surface of the feeding channel 12 close to the fixed ring 244. A second ring gear 17 meshing with the first gear 249 is fixedly connected to the inner surface of the baffle 16. A discharge port facing the feeding channel 12 and a dust exhaust pipe 322 facing the second dust filter screen 241 are respectively provided on the second mounting portion 32.

[0024] After the dual-axis output motor 313 is started, the dual-axis output motor 313 will drive the first gear ring 15 to rotate through the third gear 3132, thereby driving the outer cylinder 11 to rotate, and the rotation direction of the outer cylinder 11 is opposite to that of the outer cylinder 21. The rotation of the outer cylinder 11 drives the spiral feeding plate 13 to rotate. The spiral direction of the spiral feeding plate 13 is opposite to that of the auger-type filter screen 23. Therefore, when the outer cylinder 11 drives the spiral feeding plate 13 to rotate, the spiral feeding plate 13 promotes the sliding of qualified materials in the feeding channel 12, accelerates the sliding of qualified materials, and the qualified materials slide through the feeding channel 12 to the discharge port of the second mounting portion 32. The discharge port of the second mounting portion 32 is connected to the feed port of the ball mill to complete the feeding. In this process, since the rotation directions of the outer cylinder 11 and the outer cylinder 21 are opposite, under the differential action of the two, the second gear ring 1 7 will drive the first gear 249 to rotate rapidly around the mounting shaft 247 through meshing, thereby driving the fan blades 248 to rotate rapidly, generating negative pressure on the side of the second dust filter screen 241 close to the fixing ring 244, and sucking the dust generated in the outer cylinder 21 during the filtering and feeding process into the dust exhaust pipe 322 to avoid dust and facilitate unified collection and treatment. In the auger type filter screen 23, since the connecting plate 232 and the first dust filter screen 233 are both arranged in an arc shape, the air flow rate near the connecting plate 232 and the first dust filter screen 233 is faster than the air flow rate inside the auger type filter screen 23 during the rotation of the auger type filter screen 23 with the outer cylinder 21, and therefore the pressure is lower, so that the air inside the auger type filter screen 23 can be sucked out through the first dust filter screen 233 to prevent dust from occurring in the feeding channel 12.

[0025] In the present invention, when it is necessary to filter and feed, the first electric cylinder 41 is controlled to extend and the second electric cylinder 42 is controlled to shorten, and the outer cylinder 11 and the outer cylinder 21 are adjusted to a state where the first mounting portion 31 is higher than the second mounting portion 32, and then the rare earth material is poured into the receiving tube 51. Under the action of gravity, the material slides along the receiving tube 51 and the outer cylinder 21 toward the reprocessing cylinder 24, and the dual-axis output motor 313 is started. The two output ends of the dual-axis output motor 313 drive the second gear 3131 and the third gear 3132 to rotate synchronously. The second gear 3131 drives the third gear ring 25 to rotate through the fourth gear 315 and the limiting rotating shaft, and the third gear ring 25 drives the outer cylinder 21 to rotate, and the auger-type filter screen 23 rotates with the outer cylinder 21. The rotation makes a lot of contact with the rare earth material. During the contact process, the rare earth material of appropriate size enters the feeding channel 12 through the mesh holes on the auger filter screen 23, and the rare earth material exceeding the mesh size finally slides all the way to the reprocessing cylinder 24. The rare earth material of inappropriate particle size slides and gathers in the reprocessing cylinder 24, and then with the rotation of the reprocessing cylinder 24, driven by the protruding column 242, the rare earth material is lifted to a high place and then falls. In this process, the rare earth materials constantly collide with each other to break them. After the crushing, the rare earth material of appropriate particle size passes through the second material filter screen 243 and enters the feeding channel 12, and finally enters the ball mill along the discharge port on the second mounting portion 32 to complete the filtering and feeding. After the dual-axis output motor 313 is started, the dual-axis output motor 313 will drive the first gear ring 15 to rotate through the third gear 3132, thereby driving the outer cylinder 11 to rotate. The rotation of the outer cylinder 11 drives the spiral feeding plate 13 to rotate. The spiral direction of the spiral feeding plate 13 is opposite to the auger filter screen 23. Therefore, when the outer cylinder 11 drives the spiral feeding plate 13 to rotate, the spiral feeding plate 13 promotes the sliding of qualified materials in the feeding channel 12, accelerates the sliding of qualified materials, and the qualified materials slide through the feeding channel 12 to the second mounting portion 32. At the feeding port, the feeding port of the second mounting portion 32 is connected to the feeding port of the ball mill to complete the feeding. During this process, since the outer cylinder 11 and the outer cylinder 21 rotate in opposite directions, under the differential effect of the two, the second gear ring 17 will drive the first gear 249 to rotate rapidly around the mounting shaft 247 through meshing, thereby driving the fan blades 248 to rotate rapidly, and generating negative pressure on the side of the second dust filter screen 241 close to the fixed ring 244, and sucking the dust generated in the outer cylinder 21 during the filtering and feeding process into the dust exhaust pipe 322 to avoid dust, and at the same time facilitate unified collection and treatment; When it is necessary to discharge unqualified rare earth materials, the first electric cylinder 41 is controlled to shorten and the second electric cylinder 42 is controlled to extend, and the outer cylinder 11 and the outer cylinder 21 are adjusted to a state where the first mounting portion 31 is lower than the second mounting portion 32. During the process of changing the tilt direction of the feeding assembly 1, a contact occurs between the trigger rod 413 and 3181, and the trigger rod 413 squeezes and triggers 3181, so that the adjustment motor 318 is started, and the output end of the adjustment motor 318 drives the fourth gear ring 54 to rotate through the fifth gear 319, thereby driving the receiving tube 51 to rotate 180° and adjust it to a downward state, and then the dual-axis output motor 313 is started to drive the auger type filter screen 23 to rotate. Under the action of gravity, the rare earth materials in the reprocessing cylinder 24 slide from the reprocessing cylinder 24 to the direction of the outer cylinder 21, and are finally discharged through the receiving tube 51. In this process, the rotating auger type filter screen 23 promotes the discharge of rare earth materials and saves time.
