[0022] 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.

[0023] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only for descriptive distinction and should not be construed as indicating or implying relative importance. All electrical components mentioned in this document are electrically connected to an external main controller and 220V AC mains power, and the main controller can be a conventionally known device such as a computer that provides control.

[0024] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1-7 As shown, this utility model provides a technical solution: a screening device for chemical analysis of rare earth ores, including a box 1. The box 1 is used to provide a housing environment for the screening component 2 and the pushing component 3. The box 1 exists as a screening box. The screening component 2 is set inside the box 1 and is used to screen rare earth ores. The pushing component 3 is set outside the box 1 and is used to drive the screen plate 205 to vibrate.

[0026] like Figures 1-7As shown in the embodiment of this application, the screening component 2 includes a limiting groove 210, which is located on the inner wall of the housing 1. A spring 211 is disposed in the limiting groove 210, and a stop block 207 is disposed at one end of the spring 211. A push rod 206 is disposed on one side of the stop block 207, and the push rod 206 is located in a sliding groove 209, which is located on the inner wall of the housing 1. A baffle 201 is disposed on one side of the push rod 206, and a screen plate 205 is disposed between the baffles 201. Specifically, the limiting groove 210 is used to limit the stop block 207 and provide a receiving environment for the spring 211. The cross-section of the limiting groove 210 is convex. The push rod 206 is fixedly connected to one side of the stop block 207. 206 is connected to baffle 201. Therefore, when the screen plate 205 is performing screening operations, the screen plate 205 will drive the baffle 201 to swing. During the swinging process of the baffle 201, the push rod 206 will be driven to move along the slide groove 209. While the push rod 206 is moving, it can drive the block 207 to move along the limiting groove 210. While the block 207 is moving, it will drive the spring 211 to be compressed. The compression of the spring 211 will generate elastic potential energy. When the force on the push plate 208 is removed by the striking plate 304, the spring 211 can drive the screen plate 205 to rebound, thereby causing the screen plate 205 to return to its original position, so as to perform screening operations on the ore.

[0027] like Figures 1-7 As shown in the embodiment of this application, a pusher plate 208 is provided on one side of the screen plate 205, and a guide plate 202 is provided on one side of the outer wall of the box body 1. A discharge port 203 is provided above the guide plate 202 and is located on the box body 1. Specifically, baffles 201 are fixedly provided on both sides of the screen plate 205, and the lower surface of the baffles 201 is lower than the lower surface of the screen plate 205. This ensures that the screened ore is blocked by the baffles 201 during its fall and plays a certain guiding role. It can prevent the ore from falling onto the other screen plate 205 and damaging the sides of the other screen plate 205. The baffle 201 is damaged. The discharge port 203 on the box 1 is set according to the running trajectory of the screen plate 205 and extends to both sides of the box 1. Therefore, when the screen plate 205 is used for ore screening, the setting of the discharge port 203 will not obstruct the translation of the screen plate 205. The guide plate 202 on the screen plate 205 is also set along the moving trajectory of the screen plate 205. When the screen plate 205 is used for ore screening, during the translation of the screen plate 205, the lower surface of the baffle 201 will be in contact with the upper surface of the guide plate 202. The workers collect the ore through the guide plate 202.

[0028] like Figures 1-7As shown in the embodiment of this application, a feed hopper 101 is provided at the top of the box 1, and a collection box 204 is provided at the bottom of its inner wall. The collection box 204 is slidably disposed on the inner wall of the box 1. Specifically, during the ore screening operation, the worker pours the ore into the box 1 through the feed hopper 101. The feed hopper 101 is connected to the discharge port 203 of the crushing box. The crushing box can pre-crush the rare earth ore, thereby preventing large pieces of ore from entering the box 1 and causing blockage of the discharge port 203 corresponding to the screen plate 205. Since the crushing box is prior art, it will not be described in detail here. Two layers of screen plates 205 are provided inside the box 1, the upper layer... The screen holes on the screen plate 205 are larger than those on the lower screen plate 205, and the baffle 201 on the screen plate 205 is at the same height as the discharge port 203. It should be noted that the push rods 206 on both sides of the baffle 201 are used to limit the screen plate 205, so as to ensure that the screen plate 205 moves completely along the trajectory of the discharge port 203 when the screen plate 205 is performing screening. Due to the different settings of the screen plates 205, the screen plates 205 can be graded and screened, and the remaining ore will fall into the collection box 204. The collection box 204 is slidably set on the inner wall of the box body 1, so as to facilitate the replacement of the collection box 204.

[0029] like Figures 1-7 As shown in the embodiment of this application, the pushing component 3 includes a fixed plate 302, which is located on the outside of the housing 1. A fixed shaft 305 is provided on the inner side of the fixed plate 302, and a rocker plate 308 is provided on the outer wall of the fixed shaft 305. Specifically, the fixed shaft 305 is connected to the output end of the motor. The motors in this application are all connected to an external power supply and controlled by a control system. The motor is mounted on one of the fixed plates 302. The fixed plate 302 is used to provide an installation environment and support for the motor. The motor drives the fixed shaft 305 to rotate. During the rotation of the fixed shaft 305, it can drive the rocker plate 308 to rotate. The fixed shaft 305 and the rocker plate 308 are fixedly connected. It should be noted that the fixed shaft 305 and the housing 1 are rotatably connected.

[0030] like Figures 1-7As shown in the embodiment of this application, a fixed rod 309 is provided on one side of the rocker plate 308, a connecting rod 307 is provided on the outer wall of the fixed rod 309, a fixed rod 309 is provided on the inner wall of the other end of the connecting rod 307, and a rocker arm 306 is provided on one end of the fixed rod 309. Specifically, during the rotation of the rocker plate 308, the rocker plate 308 will drive the connecting rod 307 to rotate. The fixed rod 309 is provided on the inner wall of the connecting rod 307, and the fixed rod 309 and the connecting rod 307 are rotatably connected. The fixed rod 309 on the inner wall of one end of the connecting rod 307 is fixedly connected to the rocker plate 308, while the fixed rod 309 on the inner wall of the other end of the connecting rod 307 is fixedly connected to the rocker arm 306. Therefore, when the rocker plate 308 drives the connecting rod 307 to rotate, it simultaneously drives the rocker arm 306 to swing.

[0031] like Figures 1-7 As shown in the embodiment of this application, a crossbar 301 is provided between the rocker arms 306, and a striking plate 304 is provided on one side of the crossbar 301. A fixing rod 309 is provided on the inner wall of one end of the rocker arm 306. Specifically, the rocker arm 306 and the crossbar 301 are fixedly connected, and the crossbar 301 and the striking plate 304 are also fixedly connected. The fixing plate 302 is used to provide a support environment for the rocker plate 308, and a fixing rod 309 is provided on one side of the fixing plate 302, providing a support environment for the fixing rod 309. The fixing plate 302 is installed on the outer wall of the box 1 through a hanging plate 303, which is used to support the fixing plate 302 so that the fixing plate 302 can be suspended on the outer wall of the box 1. When the ore is being screened, the motor drives the fixed shaft 305 to rotate. During the rotation of the fixed shaft 305, the rocker plate 308 can be rotated. During rotation, the connecting rod 307 rotates synchronously, which in turn drives the rocker arm 306 to swing. The rocker arm 306 swings, and the crossbar 301 drives the striking plate 304 to swing. The swinging of the striking plate 304 drives the push plate 208 to translate, which in turn compresses the spring 211. When the striking plate 304 removes its force on the push plate 208, the compression on the spring 211 is released, allowing the spring 211 to cause the push plate 208 to rebound, thus restoring the screen plate 205 to its original position. This enables the screen plate 205 to perform ore screening. It should be noted that the connecting rod 307 and the fixed rod 309 work together to limit the swing of the rocker arm 306, thereby driving the push plate 208 to reciprocate.

[0032] The working principle of this utility model is as follows:

[0033] The feed hopper 101 of the box 1 is connected to the discharge port 203 of the crushing box. After the ore enters the box 1 through the feed hopper 101, the motor is started by the control system. The motor will drive the rocker plate 308 to rotate. During the rotation of the rocker plate 308, the connecting rod 307 will rotate. At the same time, the connecting rod 307 will drive the rocker arm 306 to swing. During the swing of the rocker arm 306, the crossbar 301 will drive the striking plate 304 to swing. The side of the striking plate 304 connected to the push plate 208 is rounded. During the swing of the striking plate 304, the push plate 208 will be pushed to move horizontally. During the horizontal movement of the push plate 208, the push plate 208 will... The screen plate 205 will be driven to perform ore screening. During the horizontal movement of the screen plate 205, the screen plate 205 will use the push rod 206 to drive the stop block 207, causing the spring 211 to be compressed. After the force on the push plate 208 is removed by the striking plate 304, the screen plate 205 will return to its original state. Under the combined action of the striking plate 304 and the spring 211, the screen plate 205 can repeatedly swing to screen the ore. The screened ore will be discharged through the discharge port 203. The staff will use the guide plate 202 to collect it. The remaining ore after screening will fall into the collection box 204 for ore recycling.

[0034] In summary, this utility model discloses a screening device for chemical analysis of rare earth ores, including a housing 1, a screening component 2 disposed inside the housing 1 for screening rare earth ores, and a pushing component 3 disposed outside the housing 1 for driving the screen plate 205 to vibrate. Under the combined action of the striking plate 304 and the spring 211, this utility model can drive the screen plate 205 to swing, thereby screening the ore. The push rod 206 and the stop block 207 restrict the movement trajectory of the screen plate 205. Multiple screen plates 205 can be used for multi-stage screening of the ore. Furthermore, the collection box 204 and the guide plate 202 can collect the screened ore and the remaining ore after screening, thereby improving resource utilization and ore screening efficiency.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
