[0036] Figure 1 This is a schematic diagram of a vibration device according to an embodiment of the present invention; Figure 2 for Figure 1 The diagram shows the connection relationship between the isolation plate and the fixed plate of the vibration device. Figure 3 for Figure 1 The diagram shows the connection relationship between the drive assembly and the vibrating plate of the vibration device. Figure 4 for Figure 1 The diagram shows the vibrating device installed inside the discharge box of the heavy medium shallow trough separator. Figures 1-4 As shown, the vibration device includes a fixed plate 1, a connecting rod 2, an isolation plate 3, a guide rod 4, a vibration plate 5, a spring 6, a limiting plate 7, and a driving assembly 8.

[0037] The fixing plate 1 is used to fix the material discharge box 12 of the heavy medium shallow trough separator to the inner wall. The fixing plate 1 has a first through hole 101. The first end of the connecting rod 2 is fixedly connected to the fixing plate 1. The isolation plate 3 is fixedly connected to the second end of the connecting rod 2 and is arranged opposite to the fixing plate 1. The isolation plate 3 has a second through hole 301. The guide rod 4 passes through the first through hole 101 and can move back and forth along the first through hole 101. The vibrating plate 5 is fixedly connected to the end of the guide rod 4 facing the isolation plate 3. The spring 6 is sleeved on the side of the fixing plate 1 facing away from the isolation plate 3 and the first end of the spring 6 is fixedly connected to the fixing plate 1. The limiting plate 7 is fixedly connected to the end of the guide rod 4 facing away from the isolation plate 3 and the second end of the spring 6 is fixedly connected to the limiting plate 7. The driving assembly 8 is driven by the vibrating plate 5 and is used to regularly drive the vibrating plate 5 away from the fixing plate 1.

[0038] The heavy medium shallow trough separator is equipped with a discharge box 12, and a heating pipe 13 is installed on the inner wall of the discharge box 12. In use, the entire vibrating device is placed inside the discharge box 12, and the fixing plate 1 is fixedly connected to the inner wall of the discharge box 12. At the same time, the isolation plate 3 is positioned facing the heating pipe 13. The isolation plate 3 has a second through hole 301, which allows the heat released by the heating pipe 13 to pass through the second through hole 301 and reach the space between the isolation plate 3 and the vibrating plate 5 to heat the air in the space. The drive assembly 8 is started, and the drive assembly 8 regularly drives the vibrating plate 5 away from the fixing plate 1 and towards the isolation plate 3, thereby driving the guide rod 4 and the limiting plate 7 connected to it to move in the same direction. Under the guidance of the guide rod 4 and the first through hole 101 on the fixing plate 1, the vibrating plate 5, the guide rod 4 and the limiting plate 7 all move along the extension direction of the guide rod 4. As the limiting plate 7 moves toward the isolation plate 3, it compresses the spring 6 between itself and the fixed plate 1. When the driving assembly 8 drives the vibrating plate 5 to move a certain distance toward the isolation plate 3, it releases the vibrating plate 5. The limiting plate 7 then loses its external force and no longer compresses the spring 6. Under the elastic force of the spring 6 recovering its deformation, the limiting plate 7 moves away from the isolation plate 3, thereby driving the guide rod 4 and the vibrating plate 5 to move in the same direction. During the recovery process, the spring 6, under the elastic force generated by the deformation, does not immediately stop in its non-compressed and non-stretched natural state, but instead reciprocates with high-frequency vibration, thus causing the limiting plate 7, guide rod 4, and vibrating plate 5 to vibrate at high frequency. The driving assembly 8 regularly drives the vibrating plate 5 away from the fixed plate 1, thus repeating the above process and causing the vibrating plate 5 to vibrate continuously. Inside the heavy medium shallow trough separator, the sorted gangue is transported to the discharge box 12 by a scraper and falls down. When the gangue falls onto the vibrating plate 5, it vibrates at a high frequency and is fully turned over under the high-frequency vibration of the vibrating plate 5. This allows all surfaces of the gangue to fully contact the surrounding high-temperature air, thoroughly drying each surface. Simultaneously, during the vibration and turning process, the gangue may collide with the surface of the isolation plate 3. The isolation plate 3 then bounces the gangue back onto the vibrating plate 5, preventing it from hitting the heating pipe 13 on the back of the isolation plate 3. During the rebound, the gangue rotates in the air, further drying the surface moisture. Finally, the gangue, with its surface moisture fully dried, falls through the gap between the isolation plate 3 and the vibrating plate 5 and is discharged from the discharge box 12.

[0039] Using the vibration device of this utility model, the driving component 8 causes the vibrating plate 5 to move away from the fixed plate 1 in a regular manner, while driving the limiting plate 7 to compress the spring 6 and release the vibrating plate 5 in a regular manner. After the vibrating plate 5 is released, the spring force of the spring 6 drives the vibrating plate 5 to vibrate at high frequency, so that the gangue falling on the vibrating plate 5 is fully vibrated and turned, and then the surfaces of the gangue are fully dried, improving the drying efficiency. Moreover, an isolation plate 3 is set between the vibrating plate 5 and the heating pipe 13 on the inner wall of the discharge box 12. After the vibrating gangue bounces to the isolation plate 3, it is rebounded back to the vibrating plate 5 without hitting the heating pipe 13, which can effectively protect the heating pipe 13 and extend the service life of the sorting machine.

[0040] like Figures 1-4 As shown, in this embodiment, both the fixed plate 1 and the vibrating plate 5 are cuboid plates. The vibrating plate 5 is disposed above the fixed plate 1, and the two are parallel and inclined. The guide rod 4 is a cylindrical rod. A first through hole 101 is opened through the fixed plate 1. The guide rod 4 passes through the first through hole 101 perpendicularly to the fixed plate 1. The upper end is fixedly connected to the vibrating plate 5, and the lower end protrudes below the fixed plate 1. The spring 6 is sleeved on the part of the guide rod 4 that protrudes below the fixed plate 1. A limit plate 7 is fixed to the lower end of the guide rod 4. The two ends of the spring 6 are fixedly connected to the lower surface of the fixed plate 1 and the upper surface of the limit plate 7, respectively. Two connecting rods 2 are provided, each bent and connected at their lower ends to opposite sides of the fixed plate 1, and at their upper ends to opposite sides of the isolation plate 3. Multiple rows of second through holes 301 are evenly distributed through the isolation plate 3 to allow heat released from the heating pipes 13 on the inner wall of the discharge box 12 to pass through. A certain space is maintained between the isolation plate 3 and the vibrating plate 5 to provide sufficient space for the falling gangue to vibrate and tumble, allowing it to fall smoothly through this space. Depending on the actual application, the specific structural dimensions of the fixed plate 1, connecting rods 2, isolation plate 3, and vibrating plate 5 can be adjusted accordingly. The driving assembly 8 can be of any structure, as long as it can regularly drive the vibrating plate 5 away from the fixed plate 1 along the extension direction of the guide rod 4 and regularly release the vibrating plate 5, allowing the spring 6 to drive the limiting plate 7, the guide tube, and the vibrating plate 5 to vibrate.

[0041] Optionally, the drive assembly 8 includes a bracket 81, a transmission ring 82, a motor 83, and a cam 84. The first end of the bracket 81 is fixedly connected to the vibrating plate 5; the transmission ring 82 has a through-hole, and its outer wall is fixedly connected to the second end of the bracket 81; the motor 83 is fixed to the inner wall of the discharge box 12; the cam 84 is fixedly connected to the output shaft of the motor 83 and is disposed within the receiving cavity. This configuration simplifies the structural composition of the drive assembly 8 and facilitates assembly and operation.

[0042] like Figure 1 , Figure 3 and Figure 4As shown, in this embodiment, the transmission ring 82 is a hollow circular ring with a cavity in the middle. The transmission ring 82 and the guide rod 4 are inclined in the same direction and are nearly parallel. The upper end of the bracket 81 is fixed to the opposite sides of the vibrating plate 5, and the lower end is fixed to the two sides of the transmission ring 82. The motor 83 is fixed to the inner wall of the discharge box 12 away from the heating tube 13. The cam 84 is a disc cam 84, which is fixedly connected to the output shaft of the motor 83 and rotates within the cavity under the drive of the motor 83. Figure 1 As shown, during the process of the highest point of the outer rim of the cam 84 rotating upwards to the highest point of the transmission ring 82, an upward force along its inclined direction is applied to the transmission ring 82. The force is transmitted to the vibration plate 5 through the transmission ring 82 and the bracket 81. The guide rod 4 and the limiting plate 7, which pass through the fixed plate 1, are fixedly connected below the vibration plate 5. Therefore, under the constraint of the guide rod 4 and the first through hole 101 on the fixed plate 1, the vibration plate 5, the guide rod 4 and the limiting plate 7 move upwards along the inclined direction of the guide rod 4 under the action of external force. During the upward movement, the limiting plate 7 compresses the spring 6. As the output shaft of motor 83 continues to rotate, the highest point of the outer rim of cam 84 rotates downwards, no longer applying external force to the top of transmission ring 82. Consequently, there is no longer external force supporting vibrating plate 5, and vibrating plate 5 is released. Limiting plate 7 is also no longer subject to external force and continues to compress spring 6. At this time, spring 6 generates reciprocating vibration during its recovery deformation, which in turn drives the limiting plate 7, guide rod 4, and vibrating plate 5, which are directly or indirectly connected to it, to vibrate. Moreover, the vibration rate of spring 6 is higher than the rotation rate of cam 84, thus driving vibrating plate 5 to vibrate at a high frequency. Therefore, after cam 84 provides one power source, spring 6 can be used to vibrate vibrating plate 5 multiple times, improving the overall vibration frequency and efficiency of the gangue, thereby achieving a more effective drying effect. Depending on the actual application, support 81 can be composed of any structure, and the connection angle between support 81 and vibrating plate 5 can be adjusted appropriately, as long as it can connect transmission ring 82 and vibrating plate 5, transmit force, and push vibrating plate 5 upwards along the inclined direction of guide rod 4 during the upward pushing of transmission ring 82 by cam 84.

[0043] Optionally, the isolation plate 3 includes a first isolation plate 302 and a second isolation plate 303 connected together. The first isolation plate 302 is inclined in the same direction as the vibrating plate 5, and the second isolation plate 303 is inclined in the opposite direction to the vibrating plate 5. This arrangement allows some of the gangue, when bounced from the vibrating plate 5 to the second isolation plate 303, to slide slowly down the second isolation plate 303 without rapidly rebounding back to the vibrating plate 5. This prevents the gangue moving at excessive speed from colliding with each other and avoids excessively strong collisions with the vibrating plate 5, which could cause deformation of the vibrating plate 5, thus improving the service life of the device.

[0044] like Figure 1 and Figure 2As shown, in this embodiment, the upper end of the connecting rod 2 is fixedly connected to the first isolation plate 302, and a second through hole 301 is provided through the first isolation plate 302. The first isolation plate 302 is inclined in the same direction as the vibrating plate 5, but its inclination angle is greater than that of the vibrating plate 5. The second isolation plate 303 is inclined in the opposite direction to the vibrating plate 5, and an obtuse angle is formed between the first isolation plate 302 and the second isolation plate 303. The specific inclination angles of the first isolation plate 302 and the second isolation plate 303 can be adjusted appropriately according to the actual application.

[0045] Optionally, the connection between the first isolation plate 302 and the second isolation plate 303 is set as a rounded corner 304. The rounded corner 304 has a speed reduction function. By using the speed reduction rounded corner 304, the falling speed of the gangue vibrating above can be reduced by friction when it falls onto the surface of the second isolation plate 303, further slowing down and buffering the falling gangue, and preventing the gangue from having an excessive impact speed and causing excessive impact on the vibrating plate 5.

[0046] like Figure 1 and Figure 2 As shown, in this embodiment, the connection between the first isolation plate 302 and the second isolation plate 303 is set as a deceleration fillet 304 on the side facing the vibration plate 5. The curvature of the fillet 304 can be adjusted according to the actual application.

[0047] Optionally, the vibration device also includes a connecting plate 9, which is connected to the fixed plate 1 and fixedly connected to the inner wall of the discharge box 12. The connecting plate 9 allows for a more flexible connection between the fixed plate 1 and the inner wall of the discharge box 12, and by increasing the cross-sectional area of ​​the connecting plate 9, the contact area between it and the inner wall of the discharge box 12 can be increased, thereby improving connection stability.

[0048] like Figure 2 As shown, in this embodiment, the connecting plate 9 is a rectangular parallelepiped. To facilitate connection with the inner wall of the discharge box 12, it is set at a certain angle to the fixing plate 1. Figure 2 The right end face of the fixing plate 1. The specific shape and structure of the connecting plate 9, as well as the included angle between it and the fixing plate 1, can be adjusted according to the actual application.

[0049] Optionally, the vibrating device also includes an extension plate 10, which is fixedly connected to the end of the vibrating plate 5 away from the isolation plate 3 and extends to the inner wall of the discharge box 12. This arrangement minimizes the gap between the vibrating device and the inner wall of the discharge box 12, preventing the falling gangue from falling through the gap without being fully vibrated and dried.

[0050] During the process of driving the vibrating plate 5 upward or releasing it to make it fall, the extension plate 10 moves synchronously with the vibrating plate 5 and does not interfere with the inner wall of the discharge box 12. Figure 4As shown, to ensure there is no gap between the extension plate 10 and the inner wall of the discharge box 12, a receiving groove 15 can be formed on the inner wall of the discharge box 12 at the position corresponding to the extension plate 10. The extension plate 10 extends into the receiving groove 15, which has a certain height. During the upward or downward movement of the vibrating plate 5, the extension plate 10 remains within the receiving groove 15 and will not interfere with the groove wall. The specific extension length of the extension plate 10 can be adjusted appropriately according to the actual application. The bracket 81 can be connected to the vibrating plate 5 or the extension plate 10.

[0051] Optionally, the vibration device further includes a directional rod 11, which is fixedly connected to the end of the extension plate 10 away from the vibrating plate 5. The directional rod 11 is inserted into the directional groove 16 opened on the inner wall of the discharge box 12 and moves along the directional groove 16. With this arrangement, the directional movement of the directional rod 11 further limits the movement direction of the vibrating plate 5, so that the vibrating plate 5 can only perform uniaxial telescopic vibration.

[0052] like Figure 3 , Figure 4 As shown, in this embodiment, two directional rods 11 are fixed at a distance from the right end of the extension plate 10, and both directional rods 11 are arranged parallel to the direction of the guide rod 4. A directional groove 16 is formed in the inner wall of the discharge box 12. When the directional rods 11 are inserted into the directional groove 16, the vibrating plate 5 and the extension plate 10 vibrate under the action of the drive assembly 8 and the spring 6. The directional rods 11 then reciprocate within the directional groove 16. Constrained by the directional rods 11 and the directional groove 16, the vibrating plate 5 can only vibrate reciprocally along the extension direction of the guide rod 4. Figure 4 As shown, when a receiving groove 15 is opened in the inner wall of the discharge box 12 and the extension plate 10 extends into the receiving groove 15, the directional groove 16 is connected to the receiving groove 15.

[0053] Optionally, multiple guide rods 4, springs 6, and limiting plates 7 are provided. Multiple first through holes 101 are provided on the fixing plate 1, with one guide rod 4 passing through one first through hole 101. One limiting plate 7 is fixedly connected to the end of one guide rod 4 facing away from the isolation plate 3, and one spring 6 is sleeved on one guide rod 4. This arrangement, through the combined action of multiple sets of guide rods 4, springs 6, and limiting plates 7, can drive the vibrating plate 5 to vibrate more stably.

[0054] like Figure 1 and Figure 2 As shown, in this embodiment, the fixing plate 1 has four first through holes 101 spaced apart, and correspondingly, four sets of guide rods 4, springs 6, and limiting plates 7 are provided. The number of sets of guide rods 4, springs 6, and limiting plates 7 can be adjusted according to actual application.

[0055] This utility model also provides a heavy medium shallow trough sorting system, including a heavy medium shallow trough sorter, the heavy medium shallow trough sorter is provided with a discharge box 12, the inner wall of the discharge box 12 is provided with a heating tube 13, and it also includes the vibration device described in any of the above embodiments, the fixing plate 1 of the vibration device is fixed to the inner wall of the discharge box 12, and the isolation plate 3 of the vibration device is arranged facing the heating tube 13.

[0056] The heavy media shallow trough sorting system of this utility model uses a drive component 8 to regularly move the vibrating plate 5 away from the fixed plate 1, while simultaneously driving the limiting plate 7 to compress the spring 6 and regularly release the vibrating plate 5. After the vibrating plate 5 is released, the spring force of the spring 6 drives the vibrating plate 5 to vibrate at high frequency, thereby fully vibrating and turning the gangue falling on the vibrating plate 5, and thus fully drying all surfaces of the gangue, improving drying efficiency. Moreover, an isolation plate 3 is set between the vibrating plate 5 and the heating pipe 13 on the inner wall of the discharge box 12. The vibrating gangue bounces back to the vibrating plate 5 after hitting the isolation plate 3, without hitting the heating pipe 13, which can effectively protect the heating pipe 13 and extend the service life of the sorting machine.

[0057] like Figure 4 As shown, in this embodiment, a heating tube 13 is fixed to the left inner wall of the discharge box 12, the fixing plate 1 of the vibration device is fixed to the right inner wall of the discharge box 12, and the isolation plate 3 is close to the left inner wall and is positioned towards the heating tube 13.

[0058] Optionally, a clearance groove 14 is provided on the inner wall of the discharge box 12, and at least a portion of the drive assembly 8 of the vibration device is disposed within the clearance groove 14. This arrangement prevents the drive assembly 8 from interfering with the inner wall of the discharge box 12 and increases the operating space of the drive assembly 8.

[0059] Figure 5 for Figure 4 The side wall sectional view of the discharge box shown is as follows: Figure 4 and Figure 5 As shown, in this embodiment, a clearance groove 14 is provided on the right inner wall of the discharge box 12 corresponding to the position of the transmission ring 82. This allows the transmission ring 82 to partially reside within the clearance groove 14 when it reciprocates under the regular drive of the cam 84, preventing interference with the inner wall of the discharge box 12 and making the placement of the transmission ring 82 more flexible. Simultaneously, to save installation space, a motor groove 17 is also provided on the right inner wall of the discharge box 12, fixing the motor 83 within it.
