[0002] Crushing equipment is a machine used to crush and grind various solid materials into smaller particles or powders. It changes the physical structure of materials through rotation, extrusion, impact, etc. to meet different production needs. It is widely used in many industries such as chemical, pharmaceutical, building materials, food, etc.

[0003] In the prior art, traditional crushing equipment usually cannot ensure that the material is fully crushed to the required particle size. During the crushing process, due to the lack of an effective circulation mechanism, the material with larger particle size cannot be sent back to the crushing device for re-crushing in time, resulting in uneven particle size of the final product and difficult to meet the quality standards. This not only affects production efficiency, but may also cause waste of resources and increased costs. Summary of the invention

As the pressure in the chamber at the bottom of the rectangular air duct increases, the pushing assembly moves to the side away from the base, and the top block can limit the maximum operating height of the pushing assembly.

[0007] Preferably, the bottom of the feed hopper is fixedly connected to the top of the screening device, the output end of the drive motor is fixedly connected to the outer side of the crushing roller, and the end of the air spring away from the baffle plate is rotatably connected to the outer wall of the guide plate. Under the thrust of the air spring, the baffle plate always maintains a tendency to deflect toward the outside of the guide plate. When the outer edge of the baffle plate contacts the outer side of the pusher assembly, the baffle plate can always contact the outer side of the pusher assembly under the push of the air spring, thereby reducing the possibility of material falling from the gap between the pusher assembly and the guide plate.

[0008] Preferably, the outer side of the rectangular air duct is fixedly connected to the outer side of the screening device, the top of the pushing assembly is in contact with the bottom of the top block, and the outer side of the shielding assembly is slidably connected to the inner wall of the rectangular air duct. When the pushing assembly runs to the highest point, the material at the top of the pushing assembly will fall into the guide plate and then re-enter the feed hopper, thereby transporting the material with larger particle size to the crushing device for re-crushing.

[0009] Preferably, the screening device includes a feeding pipe, the inner side of the feeding pipe is fixedly connected to a feeding pipe, the inner side of the feeding pipe is rotatably connected to a screen drum, the outer side of the screen drum is rotatably connected to a limiting ring, the outer side of the screen drum is fixedly connected to a gear ring, the outer side of the feeding pipe is fixedly connected to a screening motor, the output end of the screening motor is fixedly connected to a rotating shaft, the outer wall of the rotating shaft is fixedly connected to a gear, and the inner wall of the screen drum is fixedly connected to a spiral conveying plate, the screening motor drives the gear to rotate through the rotating shaft, so that the gear drives the screen drum to rotate along the inner side of the limiting ring through the gear ring, and the spiral conveying plate located on the inner side of the screen drum can rotate therewith, and when the spiral conveying plate rotates, it can transport the material that falls into the feeding pipe into the screen drum, and the qualified particles will fall downward through the holes opened on the surface of the screen drum, and the materials with larger particle size will be transported along the screen drum into the conveying device.

By arranging the spiral conveying plate in the screen drum, the material conveying speed is accelerated and the overall processing efficiency is improved. At the same time, it also helps to evenly distribute the material entering the screen drum on the cross-section of the screen drum, so that the material can more fully contact the screen surface of the screen drum, thereby improving the screening effect and quality. In the process of pushing the material, the spiral conveying plate will produce a certain stirring and turning effect on the material, so that smaller particles can pass through the sieve holes more easily.

[0011] Preferably, the pushing assembly includes a shell, the bottom of which is fixedly connected to a bottom guard frame, the top of which is rotatably connected to a storage plate, and the side of the shell away from the storage plate is fixedly connected to a top plate. The bottom of the storage plate is fixedly connected to a limiting guide rail, the bottom of the limiting guide rail is slidably connected to a slider, and the bottom of the slider is rotatably connected to a sliding rod. The outer side of the sliding rod is fixedly connected to a compression spring. The outer side of the compression spring is fixedly connected to a fixed cylinder, and during the upward movement of the pushing assembly, when the top of the top plate contacts the top block, the shell cannot continue to move upward due to the resistance of the top plate, and air enters the interior of the fixed cylinder through the hole opened at the bottom of the fixed cylinder and squeezes the compression spring upward.

[0012] Preferably, the side walls of the shell and the bottom guard frame are slidably connected to the inner wall of the rectangular air duct, the top of the top plate contacts the bottom of the top block, the outer wall of the sliding rod is slidably connected to the inner wall of the fixed cylinder, and the outer wall of the fixed cylinder is fixedly connected to the inner wall of the shell. When the compression spring is compressed, the sliding rod slides upward. At this time, the slider slides along the surface of the limiting guide rail and pushes the limiting guide rail upward. At this time, the storage plate can be deflected together with the limiting guide rail and tilted, so that the material on the surface of the storage plate can smoothly fall into the guide plate.

[0013] Preferably, the shielding assembly includes a fixed seat, the top of the fixed seat is fixedly connected to a return spring, the top of the return spring is fixedly connected to a connecting frame, and the outer side of the connecting frame is fixedly connected to a shielding shell. During the sliding process of the pushing assembly, the elastic force of the return spring located at the top of the fixed seat is gradually released, and the shielding shell is pushed upward through the connecting frame, so that when the pushing assembly moves upward, the side wall of the shielding shell can just block the opening of the side wall of the rectangular air duct.

[0014] Preferably, the bottom of the fixing seat is fixedly connected to the top of the base, the side wall of the shielding shell is slidably connected to the inner wall of the rectangular air duct, a ventilation hole is opened in the wall of the shielding shell, and the top of the shielding shell is in contact with the bottom of the bottom protective frame. When the air pump is pumping air, when the bottom of the bottom protective frame contacts the surface of the shielding shell, the return spring is compressed again. At the same time, the return spring can also buffer the impact force when the pushing assembly descends, reducing the risk of damage to the pushing assembly.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention screens the crushed material by setting a screening device. The crushed material falls into the screen drum through the discharge pipe. At this time, the screening motor drives the gear to rotate through the rotating shaft, so that the gear drives the screen drum to rotate through the gear ring. At this time, the spiral conveying plate located on the inner side of the screen drum can rotate together. When the spiral conveying plate rotates, it can transport the material that falls into the feed pipe to the screen drum, and the qualified particles will fall downward through the holes opened on the surface of the screen drum, and the material with larger particle size will be transported along the screen drum to the conveying device.

[0017] 2. The present invention speeds up the material conveying speed and improves the overall processing efficiency by arranging a spiral conveying plate inside the screen drum. It also helps to evenly distribute the material entering the screen drum on the cross section of the screen drum, so that the material can more fully contact the screen surface of the screen drum, thereby improving the screening effect and quality. In the process of pushing the material, the spiral conveying plate will produce a certain stirring and turning effect on the material, so that smaller particles can pass through the screen holes more easily, thereby improving the precision and accuracy of screening.

[0018] 3. The present invention sets a conveying device. When materials with larger particle sizes are conveyed along the screen drum into the rectangular air duct, they will fall on the surface of the pushing assembly. At this time, the air pump blows air into the rectangular air duct, and the pushing assembly moves to the side away from the base. When the pushing assembly runs to the highest point, the material on the top of the pushing assembly will fall into the guide plate and then re-enter the feed hopper. In this way, the materials with larger particle sizes can be conveyed to the crushing device for re-crushing until the materials are crushed to the required particle size. Through this cyclic crushing method, it can be ensured that the materials are fully crushed.

[0019] 4. The present invention provides a crushing device. Under the thrust of the air spring, the shielding plate always maintains a tendency to deflect toward the outside of the guide plate. When the outer edge of the shielding plate contacts the outside of the pusher assembly, the shielding plate can always contact the outside of the pusher assembly under the push of the air spring, thereby reducing the possibility of material falling from the gap between the pusher assembly and the guide plate.

[0020] 5. The present invention sets a shielding component. When the air pump blows, the gas enters the rectangular air duct. At this time, the gas blows upward through the ventilation holes, so that the pushing component can slide upward along the inner wall of the rectangular air duct to complete the material transportation process. During the sliding of the pushing component, the elastic force of the return spring located at the top of the fixed seat is gradually released, and the shielding shell is pushed upward through the connecting frame, so that when the pushing component moves upward, the side wall of the shielding shell can just block the opening of the side wall of the rectangular air duct, thereby preventing the material from entering the rectangular air duct.

[0021] 6. The present invention sets a pushing assembly. During the upward movement of the pushing assembly, when the top of the top plate contacts the top block, the shell cannot continue to move upward due to the resistance of the top plate. At this time, air enters the interior of the fixed cylinder from the hole opened at the bottom of the fixed cylinder and presses the compression spring upward, causing the sliding rod to slide upward. At this time, the slider slides along the surface of the limiting guide rail and pushes the limiting guide rail upward. At this time, the storage plate can be deflected together with the limiting guide rail and tilted, so that the material on the surface of the storage plate can smoothly fall into the guide plate.

[0022] 7. The present invention sets a shielding component. When the air pump is pumping air, the compression spring can drive the storage plate to reset and keep it level with the shell again. The entire pushing assembly moves downward to reset. During this process, when the bottom of the bottom guard frame contacts the surface of the shielding shell, the reset spring is compressed again. At the same time, the reset spring can also buffer the impact force when the pushing assembly descends, reducing the risk of damage to the pushing assembly and thereby extending the service life of the equipment.

[0037] The conveying device 4 includes a base 41, the top of the base 41 is fixedly connected to a rectangular air duct 42, the top of the rectangular air duct 42 is fixedly connected to a top block 46, the outer wall of the bottom of the rectangular air duct 42 is fixedly connected to an air pump 43, the bottom of the base 41 is fixedly connected to a shielding component 45, the inner side of the rectangular air duct 42 is slidably connected to a pusher component 44, the outer side of the rectangular air duct 42 is fixedly connected to the outer side of the screening device 1, the top of the pusher component 44 is in contact with the bottom of the top block 46, the outer side of the shielding component 45 is slidably connected to the inner wall of the rectangular air duct 42, and when the material with a larger particle size is transported to the rectangular air duct 42 along the screen drum 26, it will fall on the pusher component The surface of the push component 44 is moved by the air pump 43 into the rectangular air duct 42. As the pressure in the chamber at the bottom of the rectangular air duct 42 increases, the push component 44 moves to the side away from the base 41, wherein the top block 46 can limit the maximum operating height of the push component 44. When the push component 44 runs to the highest point, the material at the top of the push component 44 will fall into the guide plate 35 and then re-enter the feed hopper 31, thereby the material with larger particle size can be transported to the crushing device 3 for re-crushing until the material is crushed to the required particle size.

The top of the spiral conveying plate 28 and the feed pipe 21 are fixedly connected to the bottom of the feed hopper 31, the outer side of the feed pipe 21 is fixedly connected to the outer wall of the rectangular air duct 42, the inner wall of the feed pipe 21 is fixedly connected to the outer wall of the limit ring 25, the outer wall of the spiral conveying plate 28 is slidably connected to the inner wall of the feed pipe 29, the gear 24 is meshed with the gear ring 27, and the crushed material falls into the screen drum 26 through the feed pipe 21. At this time, the screening motor 22 drives the gear 24 to rotate through the rotating shaft 23. The gear 24 drives the screen drum 26 to rotate along the inner side of the limit ring 25 through the gear ring 27. At this time, the spiral conveying plate 28 located on the inner side of the screen drum 26 can rotate together with it. When the spiral conveying plate 28 rotates, the material that falls into the feeding pipe 29 can be conveyed to the screen drum 26, and the qualified particles will fall downward through the holes opened on the surface of the screen drum 26, and the materials with larger particle sizes will be conveyed to the conveying device 4 along the screen drum 26; wherein, by arranging the spiral conveying plate 28 in the screen drum 26, the conveying speed of the material is accelerated, the overall processing efficiency is improved, and it is also helpful to evenly distribute the material entering the screen drum 26 on the cross section of the screen drum 26, so that the material can be more fully in contact with the screen surface of the screen drum 26, thereby improving the screening effect and quality. In the process of pushing the material, the spiral conveying plate 28 will produce a certain stirring and turning effect on the material, so that smaller particles are more likely to pass through the sieve holes, thereby improving the screening precision and accuracy.

[0039] The push assembly 44 includes a shell 401, the bottom of the shell 401 is fixedly connected to a bottom guard frame 402, the top of the shell 401 is rotatably connected to a storage plate 403, and the side of the shell 401 away from the storage plate 403 is fixedly connected to a top plate 404. The bottom of the storage plate 403 is fixedly connected to a limiting guide rail 409, the bottom of the limiting guide rail 409 is slidably connected to a slider 408, and the bottom of the slider 408 is rotatably connected to a sliding rod 406. The outer side of the sliding rod 406 is fixedly connected to a compression spring 407. The outer side of the compression spring 407 is fixedly connected to a fixed cylinder 405. The side walls of the shell 401 and the bottom guard frame 402 are slidably connected to the inner wall of the rectangular air duct 42, the top of the top plate 404 contacts the bottom of the top block 46, and the sliding rod 40 6 is slidably connected to the inner wall of the fixed cylinder 405, and the outer wall of the fixed cylinder 405 is fixedly connected to the inner wall of the shell 401. During the upward movement of the pushing assembly 44, when the top of the top plate 404 contacts the top block 46, the shell 401 cannot continue to move upward under the resistance of the top plate 404. At this time, air enters the interior of the fixed cylinder 405 from the hole opened at the bottom of the fixed cylinder 405, and presses the compression spring 407 upward, so that the sliding rod 406 slides upward. At this time, the slider 408 slides along the surface of the limiting guide rail 409 and pushes the limiting guide rail 409 upward. At this time, the storage plate 403 can be deflected together with the limiting guide rail 409 and tilted, so that the material on the surface of the storage plate 403 can smoothly fall into the guide plate 35.

[0040] The shielding component 45 includes a fixed seat 501, the top of the fixed seat 501 is fixedly connected with a return spring 502, the top of the return spring 502 is fixedly connected with a connecting frame 503, the outer side of the connecting frame 503 is fixedly connected with a shielding shell 504, the bottom of the fixed seat 501 is fixedly connected to the top of the base 41, the side wall of the shielding shell 504 is slidably connected to the inner wall of the rectangular air duct 42, and a ventilation hole 505 is opened in the wall of the shielding shell 504. The top of the shielding shell 504 contacts the bottom of the bottom guard frame 402. When the air pump 43 blows air, the gas enters the rectangular air duct 42. At this time, the gas is blown upward through the ventilation hole 505 opened on the top of the shielding shell 504 in the shielding component 45, so that the pushing component 44 can slide upward along the inner wall of the rectangular air duct 42 to complete the material conveying process. During the process, the elastic force of the return spring 502 located on the top of the fixed seat 501 is gradually released, and the shielding shell 504 is pushed upward through the connecting frame 503, so that when the pushing assembly 44 moves upward, the side wall of the shielding shell 504 can just block the opening of the side wall of the rectangular air duct 42, thereby preventing materials from entering the rectangular air duct 42. When the air pump 43 is pumping air, the compression spring 407 can drive the storage plate 403 to reset and keep it level with the shell 401 again, and reset through the downward movement of the entire pushing assembly 44. During this process, when the bottom of the bottom guard frame 402 contacts the surface of the shielding shell 504, the return spring 502 is compressed again. At the same time, the return spring 502 can also buffer the impact force when the pushing assembly 44 descends, reducing the risk of damage to the pushing assembly 44, thereby extending the service life of the equipment.

[0041] Working principle:

[0042] When in use, the screening device 1 and the crushing device 3 are fixed by the support frame 2, and then the solid material is added from the top of the crushing device 3. After being crushed by the crusher, the solid material falls into the screening device 1 for screening, wherein qualified materials fall from the bottom of the screening device 1 to the outside of the device, and unqualified solid particles re-enter the crushing device 3 through the conveying device 4 for re-screening, and this cycle is repeated until the material is crushed to a particle size that meets the requirements. Through this cyclic crushing method, it can be ensured that the material is fully crushed, the crushing efficiency and product quality are improved, while reducing material waste and reducing production costs.

[0043] During crushing, the two crushing rollers 33 are connected together by a set of gear teeth, and then the driving motor 32 located outside the feed hopper 31 drives one of the crushing rollers 33 to rotate, so that the two crushing rollers 33 can rotate synchronously in opposite directions, so that the material in the feed hopper 31 passes through between the steel sheets 34 when the crushing rollers 33 rotate, thereby crushing the solid material;

[0044] The crushed material falls into the screen drum 26 through the discharge pipe 21. At this time, the screening motor 22 drives the gear 24 to rotate through the rotating shaft 23, so that the gear 24 drives the screen drum 26 to rotate along the inner side of the limit ring 25 through the gear ring 27. At this time, the spiral conveying plate 28 located inside the screen drum 26 can rotate together. When the spiral conveying plate 28 rotates, it can convey the material that falls into the conveying pipe 29 to the screen drum 26, and the qualified particles will fall downward through the holes opened on the surface of the screen drum 26, and the materials with larger particle sizes will be conveyed to the conveying device 4 along the screen drum 26;

[0045] Among them, by arranging a spiral conveyor plate 28 in the screen drum 26, the material conveying speed is accelerated, the overall processing efficiency is improved, and it also helps to evenly distribute the material entering the screen drum 26 on the cross section of the screen drum 26, so that the material can more fully contact the screen surface of the screen drum 26, thereby improving the screening effect and quality. In the process of pushing the material, the spiral conveyor plate 28 will produce a certain stirring and turning effect on the material, so that smaller particles can pass through the sieve holes more easily, thereby improving the screening precision and accuracy.

[0046] When the material with larger particle size is transported into the rectangular air duct 42 along the screen drum 26, it will fall on the surface of the push assembly 44. At this time, the air pump 43 blows air into the rectangular air duct 42. As the pressure in the bottom chamber of the rectangular air duct 42 increases, the push assembly 44 moves to the side away from the base 41, wherein the top block 46 can limit the maximum operating height of the push assembly 44. When the push assembly 44 runs to the highest point, the material at the top of the push assembly 44 will fall into the guide plate 35 and then re-enter the feed hopper 31. In this way, the material with larger particle size can be transported to the crushing device 3 for re-crushing until the material is crushed to the required particle size. Through this cyclic crushing method, it can be ensured that the material is fully crushed.

[0047] In this process, under the thrust of the air spring 36, the shielding plate 37 always keeps the tendency to deflect toward the outside of the material guide plate 35. When the outer edge of the shielding plate 37 contacts the outer side of the material pusher assembly 44, the shielding plate 37 is always in contact with the outer side of the material pusher assembly 44 under the push of the air spring 36, thereby reducing the possibility of materials falling from the gap between the material pusher assembly 44 and the material guide plate 35.

[0048] When the air pump 43 blows, the gas enters the rectangular air duct 42. At this time, the gas is blown upward through the ventilation hole 505 opened on the top of the shielding shell 504 in the shielding assembly 45, so that the pushing assembly 44 can slide upward along the inner wall of the rectangular air duct 42 to complete the material conveying process. During the sliding process of the pushing assembly 44, the elastic force of the return spring 502 located on the top of the fixed seat 501 is gradually released, and the shielding shell 504 is pushed upward through the connecting frame 503, so that when the pushing assembly 44 moves upward, the side wall of the shielding shell 504 can just block the opening of the side wall of the rectangular air duct 42, thereby preventing the material from entering the rectangular air duct 42;

[0049] During the upward movement of the push assembly 44, when the top of the top plate 404 contacts the top block 46, the lower shell 401 cannot continue to move upward due to the resistance of the top plate 404. At this time, air enters the interior of the fixed cylinder 405 from the hole opened at the bottom thereof, and presses the compression spring 407 upward, so that the sliding rod 406 slides upward. At this time, the slider 408 slides along the surface of the limiting guide rail 409 and pushes the limiting guide rail 409 upward. At this time, the storage plate 403 can deflect together with the limiting guide rail 409 and tilt, so that the material on the surface of the storage plate 403 can smoothly fall into the guide plate 35.

[0050] When the air pump 43 is pumping air, the compression spring 407 can drive the storage plate 403 to reset and keep it level with the shell 401 again, and reset through the downward movement of the entire pushing assembly 44. During this process, when the bottom of the bottom guard frame 402 contacts the surface of the shielding shell 504, the reset spring 502 is compressed again. At the same time, the reset spring 502 can also buffer the impact force of the pushing assembly 44 when it descends, reducing the risk of damage to the pushing assembly 44 and thereby extending the service life of the equipment.
