Description

Technical Field

[0001] This invention relates to the field of impurity removal equipment technology, and in particular to a vibrating air classifier for impurity removal. Background Technology

[0002] Air separation equipment, also known as air classifier, is a device that uses the difference in suspension velocity between materials and impurities to remove light impurities and dust by means of air power. It can also remove some heavier impurities such as stones and clods of soil.

[0003] While existing air separation equipment can precisely control the wind force and direction, it blows lighter, useful materials into the waste bin as impurities during the separation of materials and impurities. This not only wastes materials and increases production costs, but also mixes the useful materials blown into the waste bin with the impurities, increasing the difficulty and cost of waste disposal. Therefore, we propose a vibrating air separation equipment for removing impurities. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a vibratory air separation and impurity removal device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A vibrating air separation and impurity removal device includes a separation chamber with two covers on top. Inside the separation chamber is a blower for removing impurities from materials. The blower includes a motor and fan blades; the motor drives the fan blades to rotate, causing them to blow air. A feed inlet is located on one of the covers above the blower. Below the blower is a collection box for collecting the removed material. Inside the separation chamber is a screening mechanism that throws the material up, collecting any material mistakenly discharged during the pneumatic separation process. The screening mechanism throws debris and misplaced material upwards. An adjustment mechanism is installed between the fan and the screening mechanism to move the fan closer to the screening mechanism. The screening mechanism collects the misplaced material and throws the material upwards. When the screening mechanism throws the material upwards, the adjustment mechanism drives the fan to move closer to the screening mechanism, shortening the distance between the fan and the screening mechanism. The fan is then used to perform secondary sorting of the thrown material and debris.

[0007] As a preferred embodiment of the present invention, the screening mechanism includes a motor and a waste frame fixed inside the separation box. A transmission rod is fixed to the top of the motor, and a tilting plate is provided at the end of the transmission rod away from the motor. A throwing frame is provided above the tilting plate, and an oscillation mechanism is provided between the throwing frame and the waste frame. The transmission rod is L-shaped, and the throwing frame is located diagonally above the tilting plate. The end of the transmission rod away from the tilting plate is obliquely mounted on the output shaft of the motor, and the end of the transmission rod away from the motor is rotatably connected to the tilting plate. The middle part of the throwing frame is recessed inward to form a collection groove, which can collect misdischarged materials. The output shaft of the motor drives the transmission rod to rotate. The transmission rod cooperates with the tilting plate and the oscillation mechanism to make the tilting plate rotate back and forth. The tilting plate drives the throwing frame to rotate back and forth, causing the materials inside the throwing frame to be thrown upward.

[0008] As a preferred embodiment of the present invention, the oscillation mechanism includes a fixed rod rotatably connected to the outer wall of the tilting plate. A through groove is provided in the middle of the tilting plate, and a rotating shaft is rotatably installed inside the through groove. A collar is fixed in the middle of the rotating shaft, and the collar is sleeved on the end of the transmission rod away from the motor. The end of the fixed rod away from the tilting plate is fixed to the waste frame. The output shaft of the motor drives the transmission rod to rotate, and the transmission rod drives the collar to rotate. The tilting plate limits the rotating shaft, and the fixed rod limits the tilting plate, so that the transmission rod drives the collar to rotate around the axis of the rotating shaft. The rotating shaft drives the tilting plate to reciprocate around the central axis of the tilting plate, so that the tilting plate reciprocates. The tilting plate drives the throwing frame to reciprocate around the central axis of the tilting plate, so that the material inside the throwing frame moves to the end of the throwing frame away from the tilting plate and is thrown upward.

[0009] As a preferred embodiment of the present invention, two support rods are symmetrically fixed to the top of the flipping plate. Two connecting rods are inserted into the ends of the two support rods away from the flipping plate. A crossbeam is fixed between the two connecting rods. The side of the connecting rod away from the support rod is fixed to the throwing frame. A limiting rod is also movably connected to the top of the flipping plate. A threaded rod is provided between the limiting rod and the crossbeam. The crossbeam is located at the end of the two connecting rods away from the two support rods. A threaded hole adapted to the threaded rod is opened in the middle of the crossbeam. The end of the threaded rod away from the crossbeam is rotatably connected to the limiting rod. Rotating the threaded rod, the threaded rod engages with the threaded hole of the crossbeam, causing the crossbeam to move along the outer wall of the threaded rod. The crossbeam drives the connecting rod to move, and the connecting rod drives the throwing frame to move. Adjusting the distance between the throwing frame and the waste frame adjusts the amplitude and angular velocity of the throwing frame during rotation. The flipping plate drives the support rod to rotate back and forth, the support rod drives the connecting rod to rotate back and forth, and the connecting rod drives the throwing frame to rotate back and forth.

[0010] In a preferred embodiment of the present invention, a limiting ball is fitted onto the end of the threaded rod away from the limiting rod. A guide rod is also hinged to the outer wall of the transmission rod. A transmission ball is fixed to the end of the guide rod away from the transmission rod. Several conveying rollers are also provided inside the throwing frame, and several discharge ports are provided at the end of the throwing frame away from the waste box. Gaps are provided between the several conveying rollers. The end of the transmission ball away from the guide rod is movably connected to the adjusting mechanism. Pulling the limiting ball separates the limiting ball from the threaded rod. Rotating the threaded rod causes it to engage with the crossbeam, moving the crossbeam to one side of the waste box and separating the crossbeam from the threaded rod. Rotating the limiting rod causes it to drive the threaded rod to rotate, moving the threaded rod to the far end. When the end of the limit rod moves to the side closer to the waste box, and the crossbeam separates from the threaded rod, and the support rod drives the connecting rod to rotate back and forth, the connecting rod drives the throwing frame to rotate back and forth. When the end of the throwing frame closer to the fan rotates upward, the throwing frame is affected by gravity and drives the connecting rod to slide along the top of the support rod towards the side closer to the waste box. When the end of the throwing frame closer to the fan moves downward, the throwing frame is affected by gravity and drives the connecting rod to slide along the top of the support rod away from the waste box, thereby increasing the angular velocity and amplitude of the throwing frame. After the misdischarged material is separated from the debris, the throwing frame flips downward, and the material is affected by gravity, causing the material to roll downward along the gap and then be discharged through the outlet.

[0011] In a preferred embodiment of the present invention, the adjusting mechanism includes an extension rod fixed to the inner wall of the separation chamber. A main rack is located at the end of the extension rod away from the separation chamber. A gear meshes with the top of the main rack, and a secondary rack meshes with the top of the gear. A positioning shaft is rotatably connected to the middle of the gear. Both ends of the positioning shaft are fixed to the inner wall of the separation chamber. A connecting frame is fixed at the end of the main rack away from the extension rod, and a sleeve is fixed at the end of the connecting frame away from the main rack. A slot for a transmission ball is provided on the side of the sleeve away from the main rack, and the transmission ball is rotatably installed in the slot. A fan is positioned above the secondary rack. When the transmission rod rotates, it performs a circular motion, driving the guide rod. The device performs circular motion, with the sleeve limiting the transmission ball, causing the guide rod to drive the transmission ball to rotate inside the threaded rod. Simultaneously, the guide rod drives the sleeve to reciprocate through the transmission ball, which in turn drives the main rack to reciprocate. The main rack drives the gear meshing with it to rotate around the axis of the positioning shaft, and the gear drives the secondary rack to reciprocate, causing the main rack and secondary rack to move in opposite directions. When the main rack moves closer to the extension rod, it drives the gear to rotate counterclockwise, which in turn drives the secondary rack to move towards one end of the throwing frame. The secondary rack then drives the fan to move closer to the throwing frame, reducing the distance between the fan and the throwing frame, thereby performing secondary separation of the material and debris thrown up from inside the throwing frame.

[0012] As a preferred embodiment of the present invention, a connecting seat is fixed to the top of the auxiliary rack, a connecting plate is fixed to the outer wall of the connecting seat, and a partition is fixed to the top of the connecting plate. The partition is located below the feed inlet of the cover plate. When the auxiliary rack moves away from the throwing frame, the auxiliary rack drives the connecting plate to move away from the throwing frame through the connecting seat. The connecting plate drives the partition to move away from the throwing frame, so that the partition moves to the side of the feed inlet, thereby allowing the material to fall. This not only enables intermittent feeding but also seals the separation box during secondary screening of the material, preventing the material and debris inside the throwing frame from mixing with the new material and causing secondary pollution.

[0013] As a preferred embodiment of the present invention, a temporary storage basket is fixed to the outer wall of the guide rod. An arc surface is provided in the middle of the inner wall of the temporary storage basket, and grooves are provided on both sides of the arc surface. A material cylinder is also fixed below the temporary storage basket. When the material after being screened by the blower enters the interior of the temporary storage basket, the material falls onto the arc surface. Under the influence of gravity, the material moves along the arc surface and enters the interior of the groove. Then, it enters the interior of the receiving box through the material cylinder. The material is quickly discharged through the arc surface and the groove, preventing the material from accumulating inside the temporary storage basket or above the groove.

[0014] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0015] 1. This invention achieves the reciprocating flipping motion of the throwing frame through the cooperation of structures such as a fan, screening mechanism, adjustment mechanism, oscillation mechanism, tilting plate and throwing frame. This continuously throws the internal material upward, enabling the mis-discharged material and impurities to achieve secondary efficient separation in the air. The separated material can be accurately recycled and reused, reducing unnecessary material loss, significantly reducing the production cost of enterprises, and effectively reducing the difficulty and cost of subsequent waste treatment and disposal.

[0016] 2. This invention, through the cooperation of structures such as a flipping plate, support rod, connecting rod, threaded rod, crossbeam, and throwing frame, can precisely control the relative position between the throwing frame and the flipping plate. This allows the operator to accurately control the swing amplitude and rotational angular velocity of the throwing frame during rotation, thereby achieving refined management of the material handling process, helping to optimize the material separation effect and improve production efficiency.

[0017] 3. This invention, through the cooperation of structures such as a flip plate, threaded rod, limiting rod, and limiting ball, enables the connecting rod to slide smoothly along the top of the support rod when the threaded rod is separated from the crossbeam, by using the centrifugal force generated by the rotation of the throwing frame. This increases the swing amplitude and angular velocity of the throwing frame during rotation, thereby further enhancing the material separation effect and optimizing the overall operating efficiency.

[0018] 4. This invention, through the cooperation of structures such as the feeding roller, the throwing frame, and the discharge port, enables the material to roll smoothly downwards along the predetermined gap and finally be discharged accurately and efficiently through the discharge port. This not only ensures the smooth flow of the material but also effectively avoids the risk of the material being mixed with impurities again during the transmission process, thereby significantly improving the purity of the material and the overall processing efficiency, and ensuring the high efficiency and precision of the production process.

[0019] 5. This invention, through the coordination of adjustment mechanisms, main rack, auxiliary rack and gears, achieves the function of precisely shortening the distance between the material and the fan during the material throwing process. It can dynamically adjust the relative position of the material and the fan, so that the material is closer to the fan during the rising process, optimizes the airflow effect, and thus enhances the material separation efficiency.

[0020] 6. This invention achieves the shaking function of the temporary storage basket through the cooperation of structures such as guide rod, temporary storage basket, groove and material cylinder, which enables the material to be quickly discharged from the inside of the temporary storage basket, effectively preventing the material from accumulating inside the temporary storage basket or above the groove, thereby significantly improving the efficiency and smoothness of material handling.

[0037] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0038] Example: The present invention provides, as follows Figure 1 and Figure 2 The vibrating air separation and impurity removal device shown includes a separation box 1, with two cover plates 2 on the top of the separation box 1, and a blower 3 for removing impurities from the material is also provided inside the separation box 1. The blower 3 includes a motor and fan blades. The motor drives the fan blades to rotate, causing the fan blades to blow air. The cover plate 2 above the blower 3 has a feed inlet, and a receiving box 6 for collecting the material after impurity removal is also provided below the blower 3.

[0039] As can be seen from the above, when in use, the material is fed into the interior of the separation box 1 through the discharge port of the cover plate 2, and the material is separated from the impurities by the fan 3, so that the separated material falls into the interior of the collection box 6, and the collection box 6 is used to collect the separated material.

[0040] refer to Figure 3 , Figure 4 and Figure 5 As shown, the separation box 1 is equipped with a screening mechanism 4 for throwing materials. The screening mechanism 4 includes a motor 401 and a waste frame 414 fixed inside the separation box 1. A transmission rod 402 is fixed to the top of the motor 401. A tilting plate 403 is provided at the end of the transmission rod 402 away from the motor 401. A throwing frame 417 is provided above the tilting plate 403. The transmission rod 402 is L-shaped, and the throwing frame 417 is located diagonally above the tilting plate 403. The end of the transmission rod 402 away from the tilting plate 403 is obliquely mounted on the output shaft of the motor 401. One end of the motor 401 is rotatably connected to the tilting plate 403. The middle part of the throwing frame 417 is recessed inward to form a collection trough, which can collect the misdischarged material. The output shaft of the motor 401 drives the transmission rod 402 to rotate. The transmission rod 402 cooperates with the tilting plate 403 and the oscillation mechanism to make the tilting plate 403 rotate back and forth. The tilting plate 403 drives the throwing frame 417 to rotate back and forth, so that the material inside the throwing frame 417 is thrown upward. The screening mechanism 4 can collect the misdischarged material during the pneumatic separation process of the blower 3, and then throw the debris and misdischarged material inside the screening mechanism 4 upward.

[0041] refer to Figure 5 and Figure 6 As shown, a vibration mechanism is provided between the throwing frame 417 and the waste frame 414. The vibration mechanism includes a fixed rod 404 rotatably connected to the outer wall of the tilting plate 403. A through groove is opened in the middle of the tilting plate 403, and a rotating shaft 411 is rotatably installed inside the through groove. A collar 412 is fixed in the middle of the rotating shaft 411. The collar 412 is sleeved on the end of the transmission rod 402 away from the motor 401. The end of the fixed rod 404 away from the tilting plate 403 is fixed to the waste frame 414. The output shaft of the motor 401 drives the transmission rod 402 to rotate, and the transmission rod 402 carries... The rotating collar 412 rotates, limiting the rotating shaft 411 through the flip plate 403. The fixed rod 404 limits the flip plate 403, causing the transmission rod 402 to drive the collar 412 to rotate around the axis of the rotating shaft 411. The rotating shaft 411 drives the flip plate 403 to reciprocate around the central axis of the flip plate 403. The flip plate 403 reciprocates, and the flip plate 403 drives the throwing frame 417 to reciprocate around the central axis of the flip plate 403. This causes the material inside the throwing frame 417 to move to the end of the throwing frame 417 away from the flip plate 403 and then be thrown upwards.

[0042] refer to Figure 6 and Figure 7 As shown, two support rods 405 are symmetrically fixed to the top of the tilting plate 403. Two connecting rods 406 are inserted into the ends of the two support rods 405 away from the tilting plate 403. A crossbeam 407 is fixed between the two connecting rods 406. The side of the connecting rods 406 away from the support rods 405 is fixed to the throwing frame 417. A limit rod 409 is also movably connected to the top of the tilting plate 403. A threaded rod 408 is provided between the limit rod 409 and the crossbeam 407. The crossbeam 407 is located at the end of the two connecting rods 406 away from the two support rods 405. A threaded hole adapted to the threaded rod 408 is opened in the middle of the crossbeam 407. The end of the threaded rod 408 away from the crossbeam 407 is rotatably connected to the limiting rod 409. Rotating the threaded rod 408 causes it to engage with the threaded hole of the crossbeam 407, moving the crossbeam 407 along the outer wall of the threaded rod 408. The crossbeam 407 drives the connecting rod 406 to move, which in turn drives the throwing frame 417 to move. Adjusting the distance between the throwing frame 417 and the waste frame 414 adjusts the amplitude and angular velocity of the throwing frame 417 during rotation. The flipping plate 403 drives the support rod 405 to reciprocate, which in turn drives the connecting rod 406 to reciprocate, which in turn drives the throwing frame 417 to reciprocate.

[0043] refer to Figure 8 and Figure 9As shown, a limiting ball 410 is fitted onto the end of the threaded rod 408 away from the limiting rod 409. A guide rod 415 is also hinged to the outer wall of the transmission rod 402. A transmission ball 413 is fixed to the end of the guide rod 415 away from the transmission rod 402. Several conveying rollers 416 are also provided inside the throwing frame 417, and several discharge ports 418 are provided at the end of the throwing frame 417 away from the waste frame 414. A gap is provided between the several conveying rollers 416. The end of the transmission ball 413 furthest from the guide rod 415 is movably connected to the adjusting mechanism 5. Pulling the limiting ball 410 separates the limiting ball 410 from the threaded rod 408. Rotating the threaded rod 408 causes it to engage with the crossbeam 407, moving the crossbeam 407 towards one side of the waste box 414, separating the crossbeam 407 from the threaded rod 408. Rotating the limiting rod 409 causes the limiting rod 409 to drive the threaded rod 408 to rotate, thus causing the threaded rod 413 to rotate. 08 moves to the end away from the limit rod 409 and to the side near the waste box 414. When the crossbeam 407 separates from the threaded rod 408 and the support rod 405 drives the connecting rod 406 to rotate back and forth, the connecting rod 406 drives the throwing frame 417 to rotate back and forth. When the end of the throwing frame 417 near the fan 3 rotates upward, the throwing frame 417 is affected by gravity and drives the connecting rod 406 to slide along the top of the support rod 405 to the side near the waste box 414. When the end of the throwing frame 417 near the fan 3 moves downward, the throwing frame 417 is affected by gravity and drives the connecting rod 406 to slide along the top of the support rod 405 to the side away from the waste box 414, thereby increasing the angular velocity and amplitude of the throwing frame 417. After the misdischarged material is separated from the debris, the throwing frame 417 flips downward. The material is affected by gravity and rolls downward along the gap, and then is discharged through the discharge port 418.

[0044] refer to Figure 10 As shown, a temporary storage basket 9 is also fixed to the outer wall of the guide rod 415. The inner wall of the temporary storage basket 9 is provided with an arc surface in the middle, and grooves 10 are provided on both sides of the arc surface. A material cylinder 11 is also fixed below the temporary storage basket 9. When the material after being screened by the blower 3 enters the interior of the temporary storage basket 9, the material falls onto the arc surface. Under the influence of gravity, the material moves along the arc surface and enters the interior of the groove 10. Then, it enters the interior of the receiving box 6 through the material cylinder 11. The material is quickly discharged through the arc surface and the groove 10 to prevent the material from accumulating inside the temporary storage basket 9 or above the groove 10.

[0045] When air separation of materials is required, the motor of the blower 3 drives the fan blades to rotate and blow air. The output shaft of the motor 401 drives the transmission rod 402 to rotate, and the transmission rod 402 drives the collar 412 to rotate. The rotating shaft 411 is limited by the flip plate 403, and the fixed rod 404 limits the flip plate 403, so that the transmission rod 402 drives the collar 412 to rotate around the axis of the rotating shaft 411. The flip plate 403 reciprocates, the support rod 405 drives the support rod 405 to reciprocate, the support rod 405 drives the connecting rod 406 to reciprocate, and the connecting rod 406 drives the throwing frame 417 to reciprocate around the central axis of the flip plate 403, so that the material and impurities inside the throwing frame 417 are thrown upward, and the material and impurities are separated for a second time. The separated material falls back into the throwing frame 417.

[0046] refer to Figure 11 , Figure 12 and Figure 13 As shown, an adjustment mechanism 5 is provided between the blower 3 and the screening mechanism 4 to drive the blower 3 to move. The adjustment mechanism 5 includes an extension rod 501 fixed to the inner wall of the separation box 1. A main rack 502 is provided at the end of the extension rod 501 away from the separation box 1. A gear 503 meshes with the top of the main rack 502. A secondary rack 504 meshes with the top of the gear 503. A positioning shaft 505 is rotatably connected to the middle of the gear 503. Both ends of the positioning shaft 505 are fixed to the inner wall of the separation box 1. A connecting bracket 506 is fixed to the end of the rack 502 away from the extension rod 501. A sleeve 508 is fixed to the end of the connecting bracket 506 away from the main rack 502. A groove for a transmission ball 413 is provided on the side of the sleeve 508 away from the main rack 502. The transmission ball 413 is rotatably installed in the groove. The adjusting mechanism 5 can drive the blower 3 to move closer to the screening mechanism 4. The blower 3 is located above the secondary rack 504. When the transmission rod 402 rotates, the transmission rod 402 makes a circumferential movement. The transmission rod 402 drives the guide rod 415 to perform circular motion, which limits the transmission ball 413 through the sleeve 508, causing the guide rod 415 to drive the transmission ball 413 to rotate inside the threaded rod 408. At the same time, the guide rod 415 drives the sleeve 508 to reciprocate through the transmission ball 413. The sleeve 508 drives the main rack 502 to reciprocate. The main rack 502 drives the gear 503 meshing with it to rotate around the axis of the positioning shaft 505. The gear 503 drives the secondary rack 504 to reciprocate. The main rack 502 and the auxiliary rack 504 move in opposite directions. When the main rack 502 moves closer to the extension rod 501, the main rack 502 drives the gear 503 to rotate counterclockwise. The gear 503 drives the auxiliary rack 504 to move towards one end of the throwing frame 417. The auxiliary rack 504 drives the fan 3 to move closer to the throwing frame 417, making the distance between the fan 3 and the throwing frame 417 smaller, thereby separating the material and debris thrown up inside the throwing frame 417 for a secondary separation.

[0047] refer to Figure 13 , Figure 14 and Figure 15 As shown, a connecting seat 507 is fixed to the top of the secondary rack 504, a connecting plate 7 is fixed to the outer wall of the connecting seat 507, and a partition 8 is fixed to the top of the connecting plate 7. The partition 8 is located below the feed inlet of the cover plate 2. When the secondary rack 504 moves away from the throwing frame 417, the secondary rack 504 drives the connecting plate 7 to move away from the throwing frame 417 through the connecting seat 507. The connecting plate 7 drives the partition 8 to move away from the throwing frame 417, so that the partition 8 moves to the side of the feed inlet, thereby allowing the material to fall. This not only enables intermittent feeding, but also seals the separation box 1 during secondary screening of the material, preventing the material and debris inside the throwing frame 417 from mixing with the new material and causing secondary pollution.

[0048] When the misplaced material is screened a second time, the motor 401 drives the transmission rod 402 to rotate in a circular motion. The transmission rod 402 drives the guide rod 415 to rotate in a circular motion. The sleeve 508 limits the transmission ball 413, causing the guide rod 415 to drive the transmission ball 413 to rotate inside the threaded rod 408. At the same time, the guide rod 415 drives the sleeve 508 to reciprocate through the transmission ball 413. The sleeve 508 drives the connecting frame 506 to reciprocate. The connecting frame 506 drives the main rack 502 to reciprocate. When the main rack 502 moves closer to the extension rod 501, the main rack 502 drives the gear 503 to rotate counterclockwise. The gear 503 drives the secondary rack 504 to move towards one end of the throwing frame 417. The secondary rack 504 drives the fan 3 to move closer to the throwing frame 417, reducing the distance between the fan 3 and the throwing frame 417, thus separating the debris from the misplaced material a second time.

[0049] Working principle:

[0050] The motor of the fan 3 drives the fan blades to rotate and blow air. The output shaft of the motor 401 drives the transmission rod 402 to rotate. The transmission rod 402 drives the collar 412 to rotate. The rotating shaft 411 is limited by the flip plate 403 and the fixed rod 404 limits the flip plate 403, so that the transmission rod 402 drives the collar 412 to rotate around the axis of the rotating shaft 411. The flip plate 403 reciprocates. The support rod 405 drives the support rod 405 to reciprocate. The support rod 405 drives the connecting rod 406 to reciprocate. The connecting rod 406 drives the throwing frame 417 to reciprocate around the central axis of the flip plate 403, so that the material and impurities inside the throwing frame 417 are thrown upward.

[0051] Simultaneously, the motor 401 drives the transmission rod 402 to perform circular motion, which in turn drives the guide rod 415 to perform circular motion. The sleeve 508 limits the transmission ball 413, causing the guide rod 415 to drive the transmission ball 413 to rotate inside the threaded rod 408. At the same time, the guide rod 415 drives the sleeve 508 to reciprocate through the transmission ball 413. The sleeve 508 drives the connecting frame 506 to reciprocate, which in turn drives the main rack 502 to reciprocate. The main rack 502 drives the gear 503 meshing with it to rotate around the axis of the positioning shaft 505. The gear 503 drives the secondary rack 504 to reciprocate, causing the main rack 502 and the secondary rack 504 to move in opposite directions. Thus, when the throwing frame 417 flips upward to throw up the misdischarged material and impurities, the fan 3 approaches the thrown material and impurities, separating the impurities from the misdischarged material, causing the misdischarged material to fall back into the temporary storage basket 9.

[0052] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
