[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] like Figure 1 - Figure 9 As shown, a sorting vibrating screen includes a support assembly 1, a drive assembly 2 on one side of the support assembly 1, and a screening assembly 3 at the output end of the drive assembly 2. The support assembly 1 supports and fixes the drive assembly 2 and the screening assembly 3. The drive assembly 2 operates and drives the screening assembly 3 to rotate. The screening assembly 3 screens the raw materials inside. Multiple recovery components 4 are evenly arranged at the bottom of the screening assembly 3. The recovery components 4 vibrate and separate the finished products for discharge.

[0043] The support assembly 1 includes a fixing frame 101, which mainly serves to support and fix the components. The bottom of the fixing frame 101 is provided with a reinforcing frame 104, and the bottom of the reinforcing frame 104 is provided with multiple legs 102. The reinforcing frame 104 reinforces and fixes the multiple legs 102. The bottom of the legs 102 is provided with a buffer pad, which is elastic. The inner wall of the fixing frame 101 is provided with multiple horizontal plates 103. The side walls of two adjacent horizontal plates 103 are matched with the side walls of the hopper 401. The horizontal plates 103 connect and fix the hopper 401. A controller is provided on one side of the fixing frame 101, which electrically controls various electrical components.

[0044] The drive assembly 2 includes two drive shafts 204. Multiple rolling wheels 206 are evenly distributed on the outer surface of each drive shaft 204. Rotation of the drive shaft 204 drives the multiple rolling wheels 206 to rotate. A worktable 203 is provided on one side of the fixed frame 101. A reducer 202 is provided on the top of the worktable 203. The reducer 202 serves to reduce speed and steer. A drive motor 201 is provided at the input end of the reducer 202. The output end of the reducer 202 is fixedly connected to one end of the drive shaft 204. The drive motor 201 starts and drives the drive shaft 204 to rotate through the reducer 202. Multiple connecting frames 207 are evenly distributed on the top of the fixed frame 101. A bearing seat 205 is provided on the top of each connecting frame 207. The inner wall of the bearing seat 205 is connected to the outer surface of the drive shaft 204, providing rotational support for the drive shaft 204.

[0045] The screening assembly 3 includes multiple drum screens 301. The drum screens 301 rotate and screen the internal raw materials. The outer surface of the drum screens 301 is provided with a protective shell 306. The protective shell 306 wraps and protects the internal drum screens 301. At the same time, the protective shell 306 can also collect and recycle the finished products generated when the drum screens 301 rotate and screen, further improving the recycling efficiency and recycling effect.

[0046] The bottom of the protective shell 306 is fixedly connected to the top of the hopper 401, and the inner bottom of the protective shell 306 is connected to the interior of the hopper 401. Therefore, the finished product screened by the rotating drum screen 301 enters the interior of the hopper 401 along the inner wall of the protective shell 306 for subsequent vibration recovery. The distance between the inner wall of the protective shell 306 and the outer surface of the drum screen 301 is matched. One end of the drum screen 301 is provided with a feed hopper 303, and raw materials are poured into the drum screen 301 along the feed hopper 303. The other end of the drum screen 301 is provided with a discharge hopper 304. Both the feed hopper 303 and the discharge hopper 304 are connected to the interior of the drum screen 301. The impurities generated after the raw materials are screened by the drum screen 301 are directly discharged along the discharge hopper 304. Furthermore, the protective shell 306 is rotatably connected to the feed hopper 303 and the discharge hopper 304 through bearings. When the feed hopper 303 and the discharge hopper 304 drive the drum screen 301 to rotate, they will not drive the protective shell 306 to rotate.

[0047] The drum screen 301 has multiple screen holes 302 evenly distributed inside. The diameter of the screen holes 302 gradually increases from the end of the feed hopper 303 to the end of the discharge hopper 304. The screen holes 302 rotate and screen according to the volume of the raw material. The outer surfaces of both the feed hopper 303 and the discharge hopper 304 are provided with sliding rings 311. The outer surface of the sliding rings 311 is in frictional sliding connection with the outer surface of the rolling wheel 206. The rotation of the rolling wheel 206 drives the feed hopper 303 and the discharge hopper 304 to rotate through frictional transmission with the sliding rings 311. The drum screen 301 between the feed hopper 303 and the discharge hopper 304 rotates. Multiple splicing rings 305 are symmetrically provided on the outer surface of the drum screen 301 and the inner wall of the feed hopper 303 and the discharge hopper 304. Adjacent splicing rings 305 are fixedly connected by threads. The splicing rings 305 further improve the connection and fixing effect of the feed hopper 303, the discharge hopper 304 and the drum screen 301. When the feed hopper 303 and the discharge hopper 304 rotate, they can also synchronously drive the drum screen 301 to rotate and stir and screen the raw materials inside.

[0048] The drum screen 301 has multiple evenly spaced snap-fit ​​holes 313 inside. A stirring plate 307 is installed on the inner wall of each snap-fit ​​hole 313. When the drum screen 301 rotates, it synchronously drives the stirring plate 307 to rotate. The stirring plate 307 obstructs and agitates the raw materials inside the drum screen 301, further improving the mixing and screening effect. The stirring plate 307 has an inner hole 308 inside. A movable plate 310 is slidably connected to the inner wall of the inner hole 308. The movable plate 310 can move inside the inner hole 308 and adjust the length of the stirring plate 307 accordingly, thereby adjusting the mixing and screening effect of the raw materials inside the drum screen 301. The end of the stirring plate 307 away from the central axis of the drum screen 301 is equipped with... The elastic plate 312 is matched with the collision head 418. Multiple connecting springs 309 are evenly provided on the side wall of the elastic plate 312. The other end of the connecting spring 309 is fixedly connected to one end of the movable plate 310. The setting of the connecting spring 309 ensures the elastic reset performance of the movable plate 310. Therefore, when the drum screen 301 drives the stirring plate 307 to rotate, the bottom of the elastic plate 312 will continuously collide with the top of the collision head 418 and generate vibration force. This force drives the movable plate 310 to move up and down inside the inner hole 308 inside the stirring plate 307 through the connecting spring 309, further improving the vibration screening effect of the raw materials inside the drum screen 301.

[0049] The recycling component 4 includes multiple feeding hoppers 401, which vibrate to feed finished products of different sizes. Each feeding hopper 401 has an inner cavity 402 for gas circulation. A sealing plate 403 is slidably connected inside the inner cavity 402. The sealing plate 403 moves up and down inside the inner cavity 402, causing the gas inside the inner cavity 402 to circulate. Multiple moving rods 404 are evenly arranged on the top of the sealing plate 403. The top of the moving rods 404 is equipped with a collision head 418. Therefore, when the sealing plate 403 moves up and down, it synchronously drives the moving rods 404 to move up and down. The moving rods 404 drive the collision heads 418 to move up and down. The moving rods 404 are equipped with vent holes 405 for gas circulation. Multiple vertical rods 410 are evenly arranged on the bottom of the sealing plate 403. The vertical movement of the sealing plate 403 synchronously drives the vertical rods 410 below to move up and down.

[0050] The vent 405 is equipped with a one-way exhaust valve 406, which is used to discharge gas from the inner cavity 402 in one direction. The exhaust direction of the one-way exhaust valve 406 is along the inner cavity 402 to the inner wall of the protective shell 306. Therefore, the gas discharged from the vent 405 can not only clean the inside of the protective shell 306 by airflow, but also block the finished product inside the protective shell 306 by airflow, further realizing the stable discharge of the finished product. The inner wall of the hopper 401 and above the sealing plate 403 is evenly provided with multiple side holes 407. The side holes 407 are equipped with one-way air inlet valves 408. The one-way air inlet valves 408 allow air to enter. The direction is from the outside to the inside of the inner cavity 402. When the sealing plate 403 moves downward inside the inner cavity 402, the volume inside the inner cavity 402 increases and the pressure decreases. Outside gas can enter the inner cavity 402 through the one-way air inlet valve 408 inside the side hole 407. Then, when the sealing plate 403 moves upward inside the inner cavity 402, the volume inside the inner cavity 402 decreases and the pressure increases. The gas inside the inner cavity 402 can be discharged to the inner wall of the protective shell 306 through the one-way exhaust valve 406 inside the vent hole 405 and block the finished product with wind force, further improving the continuous and stable flow of the finished product inside the protective shell 306 into the downward hopper 401 for discharge.

[0051] Multiple return springs 409 are evenly provided at the bottom of the inner cavity 402. The top of the return spring 409 is fixedly connected to the bottom of the sealing plate 403. The return spring 409 is located on the outer surface of the vertical rod 410. The setting of the return spring 409 further improves the elastic return performance of the sealing plate 403. Therefore, when the moving rod 404 drives the collision head 418 to move upward, the top of the collision head 418 collides with the bottom of the elastic plate 312. The elastic plate 312 drives the movable plate 310 to move upward through multiple connecting springs 309. The movable plate 310 improves the mixing effect of raw materials inside the drum screen 301.

[0052] Multiple limiting holes 417 are evenly provided on the upper part of the inside of the hopper 401. The inner wall of the limiting hole 417 is slidably connected to the outer surface of the moving rod 404. The limiting hole 417 seals and limits the moving rod 404, ensuring that the gas inside the inner cavity 402 can flow along the vent hole 405. Multiple matching holes 419 are evenly provided on the lower part of the inside of the hopper 401. The inner wall of the matching hole 419 matches the outer surface of the vertical rod 410. The setting of the matching hole 419 ensures the vertical movement effect of the vertical rod 410. The diameter of the matching hole 419 is greater than the diameter of the vertical rod 410. The diameter of the return spring 409 is greater than the diameter of the matching hole 419. Therefore, the setting of the return spring 409 improves the movement stability of the vertical rod 410.

[0053] The bottom of the feeding hopper 401 is provided with a guide box 411, and the inner wall of the guide box 411 is provided with a crossbeam 415. The tops of the guide box 411 and the crossbeam 415 are fixedly connected to the bottoms of multiple vertical rods 410. When the guide box 411 moves up and down, it drives the vertical rods 410 to move up and down through the crossbeam 415. The inside of the guide box 411 is provided with an inclined slide 416. The top of the inclined slide 416 corresponds to the bottom output end of the feeding hopper 401. The finished product inside the feeding hopper 401 slides directly out along the inclined slide 416. The top of the guide box 411 is provided with a U-shaped frame 412. Multiple mounting seats 413 are evenly provided on the top of the U-shaped frame 412. The top of the mounting seat 413 is provided with a vibration motor 414. The vibration motor 414 works and drives the guide box 411 to vibrate up and down through the mounting seat 413 and the U-shaped frame 412, thereby realizing the vibration feeding of the finished product inside the inclined slide 416, realizing the vibrating drum screening process of the raw materials, and ensuring the screening quality.

[0054] When the drum screen 301 rotates and screens the raw materials, dust and impurities in the raw materials easily adhere to the inner wall of the drum screen 301 and block the inside of the screen holes 302, thus affecting the stability and smoothness of the subsequent material feeding. Furthermore, when there is too much finished product inside the inclined chute 416, it indicates that the material feeding rate inside the drum screen 301 or the protective shell 306 is too fast, which will cause the finished product inside the inclined chute 416 to become blocked and affect the normal feeding of subsequent raw materials. Conversely, when there is too little finished product inside the inclined chute 416, it indicates that the screen holes 302 inside the drum screen 301 are blocked, causing the material inside the drum screen 301 to be unable to feed stably, thus preventing the material from being fully and effectively vibrated and screened. After the drum screen 301 completes the screening of the raw materials, a large amount of dust and impurities easily adhere to the inside of the screen holes 302 and the inner wall of the protective shell 306. If these are not thoroughly and effectively cleaned, it will affect the subsequent vibrating screening.

[0055] To solve the above problems, in actual use, the controller first controls the drive motor 201 to start and drives the transmission shaft 204 to rotate inside multiple bearing seats 205 through the reducer 202. The rotation of the transmission shaft 204 drives multiple rolling wheels 206 to rotate. The rolling wheels 206 and the sliding ring 311 rub against each other and drive the feed hopper 303 and the waste discharge hopper 304 to rotate. The feed hopper 303 and the waste discharge hopper 304 synchronously drive the drum screen 301 to rotate inside the protective shell 306, thereby achieving the subsequent rotational screening effect of the raw materials.

[0056] The raw material is then poured into the drum screen 301 through the feed hopper 303. The continuous rotation of the drum screen 301 drives the raw material to rotate. At the same time, the raw material comes into contact with and collides with the stirring plate 307 and the moving plate 310 and is thoroughly stirred and mixed. The finished product with the correct size falls down through the corresponding screen holes 302 to the inner wall of the protective shell 306. The raw material continues to slide down and enters the inclined chute 416 inside the guide box 411 through the feed hopper 401 for guidance and discharge, further improving the flow recovery effect of raw materials of different sizes.

[0057] At the same time, the controller controls the vibration motor 414 to start the initial power and continuously generate vibration force. This vibration force is transmitted to the guide box 411 through the mounting base 413 and the U-shaped frame 412 and drives the guide box 411 to vibrate continuously. With the help of this vibration force, the finished product inside the inclined chute 416 can be driven to vibrate up and down continuously, which effectively avoids the accumulation of finished product inside the inclined chute 416 and affects the screening and feeding stability of the subsequent drum screen 301.

[0058] As the guide box 411 vibrates up and down, it synchronously drives multiple vertical rods 410 to move up and down. The vertical rods 410 drive the moving rods 404 to move up and down through the sealing plate 403. The moving rods 404 drive the collision head 418 at the top to move up and down. The collision head 418 continuously vibrates back and forth with the outer surface of the drum screen 301, and in conjunction with the continuous rotation of the drum screen 301, it improves the flowability of the raw materials inside the drum screen 301 and the discharge of the finished product inside the screen holes 302, ensuring that the drum screen 301 rotates and screens continuously and stably. The vertical movement of the moving rods 404... The diameter is larger than the diameter of the screen hole 302, thus avoiding the obstruction of the rotation of the drum screen 301 when the moving rod 404 moves up and down. After the collision head 418 and the outer surface of the drum screen 301 are pressed and contacted, the moving rod 404 can no longer drive the collision head 418 to move upward. When the drum screen 301 rotates, it drives multiple screen holes 302 to rotate. At this time, the collision head 418 collides with the end of the stirring plate 307 inside the drum screen 301, further realizing mutual vibration and friction, and improving the crushing, mixing and screening effect of the raw materials inside the drum screen 301.

[0059] Simultaneously, as the moving rod 404 drives the collision head 418 to move up and down, the collision distance between the top of the collision head 418 and the bottom of the elastic plate 312 changes continuously. In conjunction with the rotation of the stirring plate 307 driven by the drum screen 301, the elastic plate 312 drives the movable plate 310 to move up and down repeatedly inside the inner hole 308 through the connecting spring 309, further improving the reciprocating collision crushing effect of the movable plate 310 on the raw materials inside the drum screen 301, and ensuring that the raw materials inside the drum screen 301 can be continuously and stably crushed and screened.

[0060] Furthermore, as the sealing plate 403 moves up and down continuously inside the inner cavity 402, the pressure exerted by the sealing plate 403 on the gas inside the inner cavity 402 changes continuously. As a result, external gas continuously enters the inner cavity 402 through the one-way air inlet valve 408 inside the side hole 407, while the gas inside the inner cavity 402 continuously exits through the one-way exhaust valve 406 inside the vent hole 405 to the inside of the protective shell 306. This further achieves pulsed wind resistance to the finished product inside the protective shell 306, ensuring the fluidity and stability of the finished product as it continuously slides down into the discharge hopper 401 inside the protective shell 306. This effectively prevents the finished product from accumulating inside the protective shell 306 and affecting the discharge efficiency.

[0061] When the amount of finished product inside a certain inclined chute 416 increases, it indicates that the raw materials inside the drum screen 301 have been screened, but the amount of finished product accumulated inside the protective shell 306 is too large. Therefore, it is necessary to reduce its feeding rate accordingly to ensure that the finished product inside the inclined chute 416 is vibrated out first, and then the finished product inside the protective shell 306 is subjected to subsequent feeding processes. As the amount of finished product inside the inclined chute 416 increases, the weight inside the guide box 411 increases accordingly, and the horizontal frame 415 drives multiple vertical rods 410 to move downward. The distance between the top of the guide box 411 and the bottom of the feeding hopper 401 increases, and the inclined chute 416 can be loaded with more finished product. With the help of the vibration motor 414, the guide box 411 vibrates continuously, further ensuring that the finished product inside the inclined chute 416 can slide down and be discharged more efficiently and continuously, improving the stability and continuity of feeding.

[0062] When the guide box 411 moves the vertical rod 410 downward, the vertical rod 410 moves the sealing plate 403 downward inside the inner cavity 402. Simultaneously, the sealing plate 403 moves the moving rod 404 and the top impact head 418 downward. Therefore, the vibration force generated by the vibrating motor 414 causes the moving rod 404 and the top impact head 418 to vibrate and descend synchronously. The moving rod 404 moves the top impact head 418 upward, reducing the contact time between the impact head 418 and the outer surface of the drum screen 301. The impact head 418 then impacts the inner surface of the drum screen 301. The vibration feeding efficiency of the raw material is reduced, and the squeezing force applied to the elastic plate 312 by the collision head 418 is reduced. The elastic plate 312 drives the movable plate 310 to move up and down inside the inner hole 308 by the connecting spring 309, which reduces the distance. The collision crushing force applied by the movable plate 310 to the raw material inside the drum screen 301 is reduced, thereby reducing the rate at which the raw material inside the drum screen 301 enters the protective shell 306 along the screen hole 302, avoiding the accumulation of finished products inside the protective shell 306 and affecting the subsequent normal screening and feeding.

[0063] Simultaneously, the moving rod 404 causes the sealing plate 403 to vibrate up and down inside the inner cavity 402, increasing the amount of external gas entering the inner cavity 402 through the one-way air inlet valve 408 inside the side hole 407. Then, the sealing plate 403 moves upward, squeezing the gas inside the inner cavity 402 and increasing the amount of gas discharged through the one-way exhaust valve 406 inside the vent hole 405. This discharged gas volume further enhances the wind resistance effect on the finished product inside the protective shell 306, reducing the discharge rate of the finished product inside the protective shell 306 into the inclined chute 416 along the discharge hopper 401. This ensures that the finished product inside the inclined chute 416 is continuously vibrated and discharged, preventing excessive accumulation of finished product inside the inclined chute 416 and ultimately affecting the normal screening quality of the drum screen 301 and the sliding discharge stability of the inclined chute 416.

[0064] When the amount of finished product inside the inclined chute 416 decreases, it indicates that the raw material inside the drum screen 301 has accumulated or the screen holes 302 have become clogged, resulting in low screening efficiency. Therefore, it is necessary to thoroughly crush and mix the raw material inside the drum screen 301 and clear the blockage in the screen holes 302. As the amount of finished product inside the inclined chute 416 decreases, the weight of the guide box 411 decreases, and the downward force exerted on the multiple vertical rods 410 by the crossbeam 415 decreases. Under the elastic force of the return spring 409, the sealing plate 403 moves upward along the inner cavity 402 by an increased distance. The sealing plate 403 then drives the top collision head 418... As the upward movement distance increases, the vibrating motor 414 continuously operates and drives the moving rod 404 and the top collision head 418 to move up and down. This increases the collision force between the collision head 418 and the drum screen 301, further improving the vibration and unblocking effect of the collision head 418 on the drum screen 301. At the same time, due to the increased contact time between the collision head 418 and the drum screen 301, and in conjunction with the rotation of the drum screen 301, the pressure between the collision head 418 and the outer wall of the drum screen 301 and the stirring plate 307 increases. Under this vibration, the stirring plate 307 further improves the mixing, stirring and crushing effect of the raw materials inside the drum screen 301.

[0065] Furthermore, due to the increased contact area between the collision head 418 and the outer surface of the drum screen 301, the area for scraping and cleaning the blockage material inside the screen hole 302 by the collision head 418 is increased, further improving the unblocking and flowability inside the screen hole 302. When the drum screen 301 drives the stirring plate 307 to rotate, the pressure between the top of the collision head 418 and the bottom of the elastic plate 312 increases. The elastic plate 312 drives the movable plate 310 to move a greater distance closer to the central axis of the drum screen 301 inside the inner hole 308 through multiple connecting springs 309. This correspondingly improves the pushing and crushing effect of the movable plate 310 on the material inside the drum screen 301, ensuring that the material can be continuously and stably screened and fed.

[0066] Furthermore, as the movement amplitude of the sealing plate 403 within the inner cavity 402 decreases, the amount of external gas entering the inner cavity 402 through the one-way inlet valve 408 inside the side hole 407 decreases, and the amount of gas discharged from the inner cavity 402 to the protective shell 306 through the one-way exhaust valve 406 inside the vent hole 405 decreases. This reduces the reverse thrust exerted by the gas on the finished product inside the protective shell 306, allowing the finished product inside the protective shell 306 to continuously and efficiently fall along the feed hopper 401 into the inclined chute 416. This ensures the feeding speed and stability of the finished product inside the inclined chute 416, preventing blockage inside the drum screen 301 and reducing the recycling efficiency of the finished product.

[0067] After the vibratory screening of the raw materials inside the drum screen 301 is completed, the controller controls the vibratory motor 414 to start at maximum power, and no more finished products are discharged from the inclined chute 416. At this time, under the elastic force of the return spring 409, the sealing plate 403 moves upward along the inner cavity 402 to the maximum distance. At this time, the maximum vibration force generated by the vibratory motor 414 is synchronously transmitted to the end of the sealing plate 403 through the guide box 411 and the vertical rod 410. The sealing plate 403 drives the moving rod 404 to move up and down to the maximum amplitude. The moving rod 404 drives the collision head 418 to apply the collision force to the outer surface of the drum screen 301 to the maximum value and further improves the vibration scraping effect on the dust and impurities attached to the outer surface of the drum screen 301.

[0068] At the same time, the contact area between the impact head 418 and the outer surface of the drum screen 301 reaches its maximum value, and the scraping and cleaning effect of the impact head 418 on the material blocking the screen hole 302 reaches its maximum value, further improving the unblocking and clearing effect on the screen hole 302. During this process, the squeezing force applied by the impact head 418 to the elastic plate 312 reaches its maximum value. The elastic plate 312 drives the movable plate 310 to move along the inner hole 308 to the maximum distance near the central axis of the drum screen 301 through the connecting spring 309. The movable plate 310 and the inner wall of the inner hole 308 are fully scraped and cleaned, and the cleaning effect on the outer surface of the movable plate 310 is correspondingly improved.

[0069] When the vibrating motor 414 drives the sealing plate 403 to move up and down inside the inner cavity 402 to its maximum amplitude, the amount of gas entering the inner cavity 402 through the one-way air inlet valve 408 inside the side hole 407 reaches its maximum value. The amount of gas discharged from the inner cavity 402 through the one-way exhaust valve 406 inside the vent hole 405 to the protective shell 306 reaches its maximum value. With the help of this gas, the inner wall of the protective shell 306 can be thoroughly and effectively cleaned by airflow, so as to fully remove dust and impurities from the inner wall of the protective shell 306 and avoid the dust and impurities from affecting the subsequent vibrating screening of raw materials.

[0070] After cleaning the inner wall of the drum screen 301 and the protective shell 306, continue to pour raw materials into the drum screen 301 along the feed hopper 303, and repeat the above process continuously while performing vibration screening of the raw materials.

[0071] This sorting vibrating drum screen boasts high screening efficiency and excellent screening effect, meeting actual requirements for raw material screening. It is simple to operate, safe and stable, with strong adaptability to material feeding, high stability, strong controllability, and good unblocking properties. During the vibrating screening process, it simultaneously clears blockages in the drum screen 301 through collision and pushes the finished product inside the protective shell 306 with reverse gas, correspondingly driving the movable plate 310 up and down and improving the collision and crushing effect on the raw material inside the drum screen 301. When the amount of finished product inside the inclined chute 416 increases, the sealing plate 403 drives the moving rod 404 and the top collision head 418 to move downwards, increasing the amount of gas discharged from the inner cavity 402 through the vent 405 and correspondingly increasing the reverse gas thrust on the raw material inside the protective shell 306. The system ensures that the finished product inside the protective shell 306 continuously and stably flows into the inclined chute 416 along the feed hopper 401 for feeding. Simultaneously, when the amount of finished product inside the inclined chute 416 decreases, the sealing plate 403 drives the moving rod 404 and the top collision head 418 to move upwards. The collision head 418 enhances the collision and unblocking effect on the drum screen 301. At the same time, the movable plate 310 moves outwards along the inner hole 308, increasing the collision and crushing effect on the raw materials inside the drum screen 301. Furthermore, after vibratory screening, the collision head 418's vibration unblocking effect on the drum screen 301 and the increased reverse gas thrust from the vent 405 further unblock the drum screen 301 and the protective shell 306, effectively preventing any impact on the subsequent vibration screening effect.
