[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Embodiment 1, by Figures 1 to 8The present invention comprises an inverted L-shaped base 1, two fixed vertical plates 2 are installed on the inner side of the inverted L-shaped base 1, and a rotating shaft 3 is rotatably installed on the upper parts of the opposite sides of the two fixed vertical plates 2. A connecting ring 4 is fixedly installed between the ends of the two rotating shafts 3, an extraction cylinder 5 is installed in the middle of the connecting ring 4, a rotating cover 6 is installed on the top of the extraction cylinder 5, and a first gear ring 7 and a second gear ring 8 are fixedly installed on the surface of the extraction cylinder 5 and the surface of the rotating cover 6 respectively. A transmission assembly 9 is installed on one side of the connecting ring 4, the upper part of the transmission assembly 9 is transmission-connected to the first gear ring 7 and the second gear ring 8, and the lower part of the transmission assembly 9 is transmission-connected to the lower part of one of the fixed vertical plates 2. The lower part of the extraction cylinder 5 is fixedly connected to the lower part of the extraction cylinder 5. A toggle lever 10 is fixedly mounted on one side, a transmission rod 11 is mounted on the top of the inverted L-shaped base 1, one end of the toggle lever 10 passes through one of the fixed vertical plates 2 and is connected to the transmission rod 11, a motor 12 is mounted on one side of the inverted L-shaped base 1, the output end of the motor 12 is in transmission connection with the bottom of the transmission rod 11, a mounting shaft 13 is fixedly mounted on the bottom of the rotating cover 6, and stirring blades 14 are equidistantly and staggeredly mounted on the surface of the mounting shaft 13; a discharge pipe 42 is mounted on the bottom of the extraction cylinder 5, a valve 43 is mounted in the middle of the discharge pipe 41, a feed pipe 44 is mounted on the top of the rotating cover 6, and a sealing cover 45 is rotatably mounted on the top of the feed pipe 43, thereby enabling efficient feeding and discharging of materials;

[0031] A sleeve groove 15 is formed in the middle of the connecting ring 4, and a mounting ring 16 is fixedly mounted in the middle of the extraction cylinder 5. The mounting ring 16 is rotatably mounted inside the sleeve groove 15, so that the extraction cylinder 5 can be effectively installed and rotated.

[0032] The transmission assembly 9 includes a transmission shaft 901, a first gear 902, a second gear 903, and a third gear 904. The transmission shaft 901 is rotatably mounted on one side of the connecting collar 4. The first gear 902 is fixedly mounted on the upper portion of the transmission shaft 901. The third gear 904 is rotatably mounted on the top of the connecting collar 4 and is meshed between the first ring gear 7 and the first gear 902. The third gear 904 is located on the top of the transmission shaft 901 and is meshed with the second ring gear 8, thereby effectively adjusting the rotation of the extraction cylinder 5 and the rotating cover 6.

[0033] When the transmission shaft 901 rotates, the transmission shaft 901 drives the first gear 902 and the second gear 903 to rotate. The rotation of the first gear 902 drives the first ring gear 7 to rotate via the third gear 904. The rotation of the first ring gear 7 drives the extraction cylinder 5 to rotate. The rotation of the extraction cylinder 5 drives the mounting ring 16 to rotate stably inside the sleeve groove 15. The rotation of the second gear 903 drives the second ring gear 8 to rotate. The rotation of the second ring gear 8 drives the rotating cover 6 to rotate. At this time, the direction of rotation of the rotating cover 6 is opposite to the direction of rotation of the extraction cylinder 5. The rotation of the rotating cover 6 drives the mounting shaft 13 and the stirring blades 14 to rotate, causing the stirring blades 14 to stir the interior of the extraction cylinder 5.

[0034] The direction of rotation of the rotating cover 6 is opposite to that of the extraction cylinder 5. At the same time, the rotation of the stirring blades 14 can perform a double stirring operation, effectively ensuring the stirring effect and efficiency.

[0035] A cannula 17 is fixedly mounted on the bottom of the second gear 903, a bearing 18 is fixedly mounted on the lower part of the surface of the cannula 17, and a fixed plate 19 is fixedly mounted on the surface of the bearing 18. A square plug-in portion 20 is provided on the upper part of the transmission shaft 901, and the interior of the cannula 17 is a square groove, and the square plug-in portion 20 is plugged into the interior of the square groove. A movable ring 21 is fixedly mounted on the top of the fixed plate 19, and two supporting inclined blocks 22 are symmetrically mounted between the bottom of the movable ring 21 and the fixed plate 19, so that the second gear 903 can be effectively rotated and raised and lowered.

[0036] When the transmission shaft 901 rotates, it drives the cannula 17 to rotate through the square plug-in portion 20 and the square groove. The rotation of the cannula 17 drives the second gear 903 to rotate. The rotation of the second gear 903 drives the second ring gear 8 to rotate. When the fixing plate 19 moves downward, it drives the bearing 18 and the cannula 17 to move downward. The downward movement of the cannula 17 drives the second gear 903 to separate from the second ring gear 8. The downward movement of the fixing plate 19 causes the square plug-in portion 20 to be inserted into the interior of the square groove to maintain the effectiveness of the connection.

[0037] Three connecting and disassembling components are installed in an annular manner at equal distances between the extraction cylinder 5 and the rotating cover 6. The three connecting and disassembling components all include U-shaped blocks 23. The U-shaped blocks 23 are fixedly installed in an annular manner at equal distances on the upper part of the surface of the extraction cylinder 5. Hooks 24 are rotatably installed inside the U-shaped blocks 23. Springs 25 are connected between the lower parts of the hooks 24 and the extraction cylinder 5, and counterweights 26 are installed at the lower parts of the hooks 24. A first limiting retaining ring 27 and a second limiting retaining ring 28 are fixedly installed on the upper part of the surface of the extraction cylinder 5 and the lower part of the surface of the rotating cover 6 respectively. First balls are installed at the top of the first limiting retaining ring 27 and the top of the inner side of the hook 24 at equal distances. The bottom of the rotating cover 6 contacts the first ball, and the top of the hook 24 is hooked and connected to the top of the second limiting retaining ring 28 through the first ball. The top of the movable ring 21 contacts the lower part of the inner side of the hook 24, so that the rotating cover 6 can be effectively installed and disassembled and the rotating cover 6 can be effectively rotated and adjusted.

[0038] like Figure 4 As shown, the rotary cover 6 is installed on the top of the extraction cylinder 5. When the rotary cover 6 rotates, the first ball on the top of the first limit ring 27 and the first ball on the hook 24 enable the rotary cover 6 to be rotated stably and effectively.

[0039] When the rotating cover 6 needs to be disassembled, the fixed plate 19 is moved downward, and the downward movement of the fixed plate 19 will drive the movable ring 21 to move downward through the two supporting inclined blocks 22. The downward movement of the movable ring 21 will separate from the hook 24, and then the gravity of the counterweight block 26 and the elastic force of the spring 25 will cause the hook 24 to rotate, and finally the upper part of the hook 24 will be separated from the second limit ring 28, and then the rotating cover 6, the mounting shaft 13 and the stirring fan blade 14 can be disassembled.

[0040] Embodiment 2, based on embodiment 1, an inverted T-shaped chute 29 is provided on the upper part of one of the fixed vertical plates 2, a threaded shaft 30 is rotatably installed in the middle part of the inverted T-shaped chute 29, the top of the threaded shaft 30 extends to the top of one of the fixed vertical plates 2 and is installed with a hand wheel 32, a T-shaped moving block 31 is installed on the surface of the threaded shaft 30 and inside the inverted T-shaped chute 29, one end of the T-shaped moving block 31 is fixedly connected to one end of the fixed plate 19, so that the fixed plate 19 can be effectively raised and lowered;

[0041] By turning the hand wheel 32, the threaded shaft 30 is rotated, and the rotation of the threaded shaft 30 causes the T-shaped moving block 31 to move up and down on its surface and inside the inverted T-shaped slide groove 29. The lifting and lowering movement of the T-shaped moving block 31 drives the fixed plate 19 to be raised and lowered.

[0042] Embodiment 3, on the basis of embodiment 1, a fourth gear 33 is fixedly installed at the bottom of the transmission shaft 901, and an arc-shaped tooth 34 is fixedly installed in the middle of one of the fixed vertical plates 2, and the fourth gear 33 is meshed with the arc-shaped tooth 34, and an arc-shaped through-groove 35 is provided in the middle of one of the fixed vertical plates 2, and the toggle rod 10 passes through the arc-shaped through-groove 35, and a vertical groove 36 is provided on the upper part of the transmission rod 11, and the end of the toggle rod 10 is installed inside the vertical groove 36; an inverted T-shaped transverse groove 38 is provided at the top of the inverted L-shaped base 1, and a moving block 39 is installed inside the inverted T-shaped transverse groove 38, and the transmission rod 11 is fixedly installed on the top of the moving block 39, so that the transmission rod 11 can be effectively adjusted; racks 40 are fixedly installed on the top and bottom of the inner side of the moving block 39, and a half gear 41 is provided inside the moving block 39, and the half gear 41 is transmission-connected to the two racks 40, and the output end of the motor 12 is fixedly connected to the middle part of the half gear 41, so that reciprocating adjustment can be effectively performed;

[0043] By starting the motor 12, the half gear 41 rotates. The rotation of the half gear 41 drives the two racks 40 to move, and the two racks 40 cause the moving block 39 to reciprocate inside the inverted T-shaped horizontal groove 38. The reciprocating movement of the moving block 39 drives the transmission rod 11 to reciprocate. The reciprocating movement of the transmission rod 11 drives the toggle rod 10 to move back and forth in an arc shape inside the arc-shaped through groove 35 through the vertical groove 36. The arc-shaped reciprocating movement of the toggle rod 10 drives the extraction cylinder 5 to swing back and forth through the rotating shaft 3, thereby facilitating the mixing and stirring operation of the raw materials inside the rotating shaft 3.

[0044] This high-purity praseodymium-neodymium oxide extraction device has a variety of stirring functions, which effectively ensures sufficient and uniform extraction stirring, thereby effectively improving the extraction effect and purity.
