[0014] 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.

[0015] Please see Figures 1 to 4 This utility model provides a magnetic separation device for metal impurities in pharmaceutical and fertilizer raw materials, including a housing 1. Inclined baffles 11 are fixedly connected inside the housing 1, and a discharge port 2 is opened on one side of the housing 1. An installation frame 3 and a sieve 4 are installed inside the housing 1. Two telescopic columns 31 pass through the installation frame 3. A handle 32 is fixedly connected to one end of each telescopic column 31, and a spring 33 is fitted around the outside of each telescopic column 31. An installation plate 34 is fixedly connected to the other end of each telescopic column 31, and two insert rods 35 are fixedly connected to the installation plate 34. Electromagnets 41 are fixedly connected to the four corners of the sieve 4, and two fixing blocks 42 are fixedly connected to the sieve 4. A fastening plate 5 is fixedly connected to the outer wall of the housing 1, and a mounting plate is installed on the fastening plate 5. The material shaking mechanism 6 includes a motor 61, a connecting rod 62, and a limiting block 63. The motor 61 is fixed to the rear surface of the fastening plate 5, and the driving end of the motor 61 passes through the motor 61 and is fixed to the connecting rod 62. The limiting block 63 is rotatably connected to the connecting rod 62 through a bearing. A bracket 64 is sleeved around the limiting block 63. A limiting groove 65 is opened inside the bracket 64. The bottom end of the bracket 64 is rotatably connected to the fastening plate 5 through a bearing. A hollow rod 66 is slidably sleeved on the top of the limiting groove 65. A guide rod 67 is movably connected to the top of the hollow rod 66. Two guide blocks 68 are slidably sleeved on the outside of the guide rod 67. A transmission shaft 7 is rotatably connected between the mounting frame 3 and the screen 4 through a bearing.

[0016] Furthermore, one end of the spring 33 is fixed to the inner wall of the mounting frame 3, and the other end of the spring 33 is fixed to the mounting plate 34, ensuring that the spring 33 can stably provide a rebound force, so that the insertion rod 35 can automatically reset after pulling the handle 32, simplifying the operation process and improving the reliability of the device.

[0017] Furthermore, the fixing block 42 has a slot inside, and one end of the plug rod 35 is inserted into the slot to realize the quick installation and fixing of the screen 4. At the same time, the plug-in structure ensures that the screen 4 will not loosen during the shaking process, thus enhancing the working stability.

[0018] Furthermore, the mounting frame 3 and the telescopic column 31 are slidably connected. The mounting frame 3 has a "U"-shaped structure. The slidable connection allows the telescopic column 31 to move smoothly, and together with the spring 33, it realizes the flipping function of the sieve 4. The "U"-shaped structure enhances the strength and stability of the mounting frame 3 and extends its service life.

[0019] Furthermore, the limiting block 63 and the limiting groove 65 are adapted to each other. The limiting block 63 is slidably connected inside the limiting groove 65 to ensure that the movement trajectory of the material shaking mechanism 6 will not deviate and to prevent the connecting rod 62 from shifting during operation, thereby ensuring that the left and right reciprocating motion of the screen 4 is stable and efficient.

[0020] Furthermore, the guide block 68 is fixed to the front surface of the fastening plate 5, and one end of the guide rod 67 slides through the side wall of the box 1 and is fixed to the mounting frame 3. The guide block 68 provides sliding support for the guide rod 67, ensuring that the horizontal movement trajectory of the mounting frame 3 and the sieve 4 is stable, avoiding tilting or jamming, and improving the uniformity of metal impurity separation.

[0021] Among them, the model of motor 61 is YE2.

[0022] Working principle: The raw materials to be processed, such as pesticides and fertilizers, are poured into the sieve 4. The motor 61 and electromagnet 41 are started. The motor 61 drives the limiting block 63 to slide within the limiting groove 65 via the connecting rod 62. This causes the support 64 to perform a pendulum motion with its bottom center as the origin. Since a hollow rod 66 is slidably fitted on the top of the limiting groove 65, the support 64 can drive the guide rod 67 to move left and right within the guide block 68 during the swinging process. This causes the guide rod 67 to drive the mounting frame 3 and the sieve 4 to reciprocate left and right. This motion fully agitates the raw materials within the sieve 4, allowing the material to come into contact with the magnetic field within the sieve 4, thus processing the raw materials. Metal impurities are adsorbed onto the inner wall of the sieve 4, while non-metallic fertilizer raw materials fall through the mesh of the sieve 4 onto the inclined baffle 11 and are finally discharged from the outlet 2. After impurity removal, the motor 61 is turned off and the power supply to the electromagnet 41 is disconnected. At this time, the handle 32 is pulled outward, the spring 33 is compressed, and the insertion rod 35 is disengaged from the slot of the fixing block 42. Through the rotation of the transmission shaft 7, the sieve 4 is flipped over, causing the metal impurities to slide onto the baffle 11 and finally be discharged from the outlet 2. After the impurities are removed, the sieve 4 is rotated back to the initial position and the handle 32 is released. The restoring force of the spring 33 causes the insertion rod 35 to re-insert into the fixing block 42, restoring the working state.
