Description

Technical Field

[0001] This invention relates to the technical field of bidirectional composite impact low-energy-consumption foundry waste crushing and processing equipment, specifically a bidirectional composite impact low-energy-consumption foundry waste crushing and processing equipment. Background Technology

[0002] Foundry scrap is a synthetic material produced in the form of a crucible. A material can be stored in large quantities by melting down all of its constituent parts into foundry scrap. Foundry scrap does not possess any tooling capabilities that would pose a danger to the holder; therefore, converting hazardous materials into foundry scrap is a safe way to store hazardous materials in large quantities. Foundry scrap can be returned to the crucible or electric arc furnace for remelting. If the material contained in the foundry scrap exceeds the remaining capacity of the machine being used, the foundry scrap cannot be melted.

[0003] The feed inlet protection structure of existing crushing equipment is often fixed, and the opening size of the feed inlet generally does not have dynamic adjustment capability. When feeding large pieces of foundry waste, the fixed protection structure can easily obstruct the material's fall, which may lead to feed inlet blockage and adversely affect the normal operation of feeding. If the feed inlet size is increased to accommodate large pieces of material, the equipment often lacks a dynamically closing protective shield during the crushing operation. During the impact operation inside the crushing chamber, due to the high-speed impact, some metal fragments may be ejected from the feed inlet. This can easily lead to material loss of metal waste, and the flying fragments may also pose a mechanical injury risk to on-site workers. Summary of the Invention

[0010] Furthermore, the surface of the extrusion plate is in contact with the surface of the inclined plate, the inner pusher plate is located above the support plate, the bottom of the inner pusher plate is in contact with the top of the support plate, and the end of the spring rod away from the crushing box is fixedly connected to the surface of the outer pusher plate.

[0011] Furthermore, the impact filtering device includes a lifting wheel, the surface of which is slidably connected to the inner wall of the crushing box. A circular telescopic rod is fixedly connected to the inner wall of the crushing box. A rack is fixedly connected to the end of the lifting wheel away from the crushing box. A pull rod is fixedly connected to the bottom of the rack. A force-applying rod is fixedly connected to the end of the pull rod away from the rack. A lifting support plate is fixedly connected to the end of the force-applying rod away from the pull rod. An elastic rod is fixedly connected to the top of the lifting support plate.

[0012] Furthermore, the inner wall of the rotating rod is fixedly connected to the surface of the second threaded rod, the surface of the gear is meshed with the surface of the rack, the end of the circular telescopic rod away from the crushing box is fixedly connected to the surface of the lifting wheel, and the force-applying rod passes through the crushing box and extends to the bottom of the lifting support plate.

[0013] Furthermore, the surface of the force-applying rod is slidably connected to the inner wall of the crushing box, the end of the elastic rod away from the lifting support plate is fixedly connected to the bottom of the fixed long plate, the fixed long plate is located below the lifting rail, the impact rod is located below the support plate, the surface of the scraper is in contact with the inner wall surface of the crushing box, and the surface of the guide pulley is slidably connected to the inner wall of the lifting rail.

[0014] The present invention has the following beneficial effects: This invention employs two sets of opposing hydraulic breakers to achieve bidirectional, opposing compression and impact crushing of casting waste. Driven by a second motor, a second threaded rod, and a force-applying plate, the hydraulic breakers reciprocate in opposite directions, simultaneously applying impact forces from both sides to the casting waste such as risers and scrap castings on the support plate. Compared to unidirectional crushing, the waste is subjected to bidirectional loads simultaneously, making it more prone to cracking and crushing. This reduces the work done by the hammers in a single strike, lowers motor power loss, and achieves low-energy crushing. A retractable rod further limits and guides the movement of the hydraulic breakers, ensuring smooth operation, reducing impact wear, and extending the service life of the crushing actuators.

[0015] This invention utilizes the mechanical linkage between the protective cover and the extrusion inclined plate. The opening and closing of the protective cover synchronously drives the outer and inner pusher plates to reciprocate and push materials. When the breaker hammers are crushing in opposite directions, the extrusion inclined plate presses against the inclined plate, driving the pusher assembly to continuously push the casting waste on the support plate to the effective crushing area of ​​the bidirectional breaker hammer. When the breaker hammers retract, the spring rod elastically resets, driving the pusher assembly back to its original position, completing one pusher cycle. The inner pusher plate can slide adaptively, always fitting against the support plate surface, preventing small pieces of waste from getting stuck in the plate gaps, eliminating dead zones where local materials are not crushed, eliminating the need for manual feeding, and improving the continuity of crushing processing.

[0016] This invention uses a motor-driven threaded rod and a moving plate to drive two sets of protective covers to open and close along a sliding groove. During feeding, the protective covers open to accommodate casting waste of different sizes, preventing large pieces of material from blocking the feed inlet. During crushing, the protective covers close, completely covering the crushing chamber and blocking metal fragments that splash during high-speed crushing. This avoids material waste and eliminates safety hazards in the workshop. The pulley and telescopic rod structure ensures smooth and stable movement of the protective covers, preventing them from jamming.

[0017] In this invention, the rotation of the second threaded rod synchronously drives the rotating rod and the gear meshing transmission rack, which in turn drives the impact frame and impact rod to periodically strike the bottom of the support plate via the pull rod and force application rod. The support plate has filter holes, and the impact generates vibration, causing the molding sand and dust impurities mixed in the casting waste to be screened and discharged downward through the filter holes. This pre-separates the molding sand impurities from the metal crushed material, preventing the molding sand from being repeatedly impacted and crushed along with the metal casting, reducing the abrasion of the breaker hammer, eliminating the ineffective energy consumption caused by crushing molding sand, and truly achieving low-energy processing. The elastic rod provides a buffering effect, weakening the rigid impact of the impact rod on the support plate and preventing the support plate from cracking and being damaged by long-term impact. The circular telescopic rod, guide pulley, and guide pull rod ensure the stable guidance of the lifting and lowering movement of the impact assembly.

[0018] The impact filter device of this invention is equipped with a scraper that scrapes and cleans impurities falling from the inner wall of the crushing box as the mechanism moves, preventing molding sand debris from accumulating and clogging the inner wall of the box and around the filter holes, keeping the filter holes unobstructed, ensuring continuous discharge of impurities, avoiding the accumulation of impurities on the support plate after the filter holes are blocked, interfering with the crushing operation, reducing the frequency of downtime for cleaning, and increasing the continuous working time of the whole machine.

[0019] The present invention provides a bidirectional hydraulic breaker with crushing action, feeding action, and support plate impact screening action. Most of the power is output from the same second motor. The mechanical gear, screw, and thread mechanism realizes the sequential linkage of multiple mechanisms. It does not require multiple sets of drive motors for feeding and impact screening, thus reducing the number of motors in the whole machine, reducing equipment manufacturing costs, and reducing idle power consumption.

[0020] The present invention features a pull rod on the side of the breaker hammer, a spring rod on the pusher assembly, and an elastic rod on the impact assembly. These multiple elastic buffer structures absorb the vibration and impact loads generated by crushing impact, pushing and squeezing, and knocking and screening, thereby reducing the transmission of impact to the crushing box, reducing the overall machine vibration and noise, reducing bolt loosening and component fatigue damage, and extending the service life of the entire machine.

[0021] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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.

[0027] Please see Figure 1 - Figure 11 As shown, this invention is a bidirectional composite impact low-energy casting waste crushing and processing equipment, including a crushing box 1, a support 2 fixedly connected to the upper surface of the crushing box 1, and a support frame 3 fixedly connected to the lower surface of the crushing box 1, and also including: The anti-splash feeding device 4 includes a motor 20. When the motor 20 is turned on, the output end drives the threaded rod 22 to rotate. The surface of the motor 20 is fixedly connected to the inner wall of the support 2. The inner wall of the crushing box 1 is provided with a sliding groove 21. The material pushing and crushing device 5 includes a second motor 30. The output end of the second motor 30 drives the second threaded rod 31 to rotate. The surface of the second motor 30 is fixedly connected to the inner wall of the support frame 3. The output end of the second motor 30 is fixedly connected to the second threaded rod 31. The surface of the second threaded rod 31 is threadedly connected to a force plate 32. When the second threaded rod 31 rotates, it drives the force plate 32 to move through the thread, so that the force plate 32 pushes the breaker hammer 33 to move inside the crushing box 1. The impact filter device 6 includes a rotating rod 51. When the rotating rod 51 rotates, it drives the gear 52 to rotate. The gear 52 will drive the rack 55 to move through meshing. The gear 52 is fixedly connected to the surface of the rotating rod 51.

[0028] The anti-splash feeding device 4 includes a threaded rod 22. When the threaded rod 22 rotates, it drives the moving plate 23 to move through the thread. When the moving plate 23 moves, it drives the protective cover 24 to move inside the chute 21 through the pulley 25, thereby moving the protective cover 24 above the crushing box 1. The end of the threaded rod 22 is fixedly connected to the output end of the motor 20. The moving plate 23 is threadedly connected to the surface of the threaded rod 22. The pulley 25 is slidably connected to the inner wall of the chute 21. The telescopic rod 26 is fixedly connected to the surface of the pulley 25. The protective cover 24 is fixedly connected to the end of the pulley 25 away from the chute 21. The protective cover 24 can protect the waste material and prevent the waste material from flying out due to excessive force during crushing.

[0029] The threaded rod 22 passes through the movable plate 23 and extends to the outer end of the movable plate 23. The protective cover 24 is located above the crushing box 1. The end of the telescopic rod 26 away from the pulley 25 is fixedly connected to the inner wall of the chute 21. There are two protective covers 24.

[0030] The feeding and crushing device 5 includes crushing hammers 33. The crushing hammers 33 are close to each other to perform bidirectional crushing of the casting waste above the support plate 39. The surface of the crushing hammers 33 is fixedly connected to the end of the force plate 32 away from the second threaded rod 31. A retractable rod 35 is fixedly connected to the inner wall surface of the crushing box 1. A pressing inclined plate 36 is fixedly connected to the surface of the protective cover 24. The pressing inclined plate 36 drives the outer feeding plate 37 to move through the pressing inclined plate 34. When the outer feeding plate 37 moves, it drives the inner feeding plate 38 to push the casting waste above the support plate 39 towards the crushing hammers 33, so that the waste can fully enter the crushing hammers. Within the working range of 33, a spring rod 40 is fixedly connected to the inner wall of the crushing box 1, a fixed tension rod 41 is fixedly connected to the inner wall of the crushing box 1, a pusher outer plate 37 is fixedly connected to the end of the fixed tension rod 41 away from the crushing box 1, a pusher inner plate 38 is slidably connected to the inner wall of the pusher outer plate 37, and the pusher inner plate 38 is fully adjusted inside the pusher outer plate 37 by its own weight, so that the pusher inner plate 38 can always be in full contact with the support plate 39, further improving the stability of the pusher inner plate 38 in pushing the waste material. A support plate 39 is fixedly connected to the inner wall of the crushing box 1, and an inclined plate 34 is fixedly connected to the upper surface of the pusher outer plate 37.

[0031] The second threaded rod 31 passes through the force-applying plate 32 and extends to the outer end of the force-applying plate 32. The force-applying plate 32 passes through the crushing box 1 and extends to the surface of the breaker hammer 33. The surface of the force-applying plate 32 contacts the inner wall of the crushing box 1. The end of the retractable rod 35 away from the crushing box 1 is fixedly connected to the surface of the breaker hammer 33.

[0032] The surface of the extrusion plate 36 is in contact with the surface of the plate 34. The inner pusher plate 38 is located above the support plate 39. The bottom of the inner pusher plate 38 is in contact with the top of the support plate 39. The end of the spring rod 40 away from the crushing box 1 is fixedly connected to the surface of the outer pusher plate 37.

[0033] The impact filtering device 6 includes a lifting wheel 53, the surface of which is slidably connected to the inner wall of the crushing box 1. A circular telescopic rod 54 is fixedly connected to the inner wall of the crushing box 1. A rack 55 is fixedly connected to the end of the lifting wheel 53 away from the crushing box 1. When the rack 55 moves, it causes the force application rod 57 to move up and down inside the crushing box 1 via a push-pull rod 56. When the force application rod 57 moves, it drives the lifting support plate 58 to move. When the lifting support plate 58 moves, it drives the elastic rod 59 and the impact frame 61 to move together. At the same time, the fixed long plate 60 moves together due to the compression of the elastic rod 59. When the impact frame 61 moves upward, it drives the impact rod 62 to move, causing the impact rod 62 to strike the bottom of the support plate 39, thereby causing impurities and other objects mixed in with the crushed waste above the support plate 39 to be separated from the material. For material separation, a pull rod 56 is fixedly connected to the bottom of the rack 55, a force-applying rod 57 is fixedly connected to the end of the pull rod 56 away from the rack 55, a lifting support plate 58 is fixedly connected to the end of the force-applying rod 57 away from the pull rod 56, an elastic rod 59 is fixedly connected to the top of the lifting support plate 58, a fixed long plate 60 is slidably connected to the inner wall of the crushing box 1, an impact frame 61 is fixedly connected to the top of the lifting support plate 58, an impact rod 62 is fixedly connected to the top of the impact frame 61, a scraper 63 is fixedly connected to the bottom of the fixed long plate 60, a lifting rail 64 is fixedly connected to the inner wall of the crushing box 1, a guide pull rod 65 is fixedly connected to the inner wall of the lifting rail 64, a guide pulley 66 is fixedly connected to the end of the guide pull rod 65 away from the lifting rail 64, and a filter hole 50 is opened on the inner wall of the support plate 39.

[0034] The inner wall of the rotating rod 51 is fixedly connected to the surface of the second threaded rod 31, the surface of the gear 52 is meshed with the surface of the rack 55, the end of the circular telescopic rod 54 away from the crushing box 1 is fixedly connected to the surface of the lifting wheel 53, and the force-applying rod 57 passes through the crushing box 1 and extends to the bottom of the lifting support plate 58.

[0035] The surface of the force-applying rod 57 is slidably connected to the inner wall of the crushing box 1, the end of the elastic rod 59 away from the lifting support plate 58 is fixedly connected to the bottom of the fixed long plate 60, the fixed long plate 60 is located below the lifting rail 64, the impact rod 62 is located below the support plate 39, the surface of the scraper 63 is in contact with the inner wall surface of the crushing box 1, and the surface of the guide pulley 66 is slidably connected to the inner wall of the lifting rail 64.

[0036] In operation, when the motor 20 is turned on, its output end drives the threaded rod 22 to rotate. The rotation of the threaded rod 22 drives the moving plate 23 to move via the thread. The moving plate 23 then moves the protective cover 24 through the pulley 25 within the chute 21, causing the protective cover 24 to move above the crushing box 1. The protective covers 24 move closer or further apart, allowing the operator to properly feed different sizes of casting waste, preventing blockages caused by a small feed opening and ensuring normal machine operation. Simultaneously, when the machine is crushing the internal casting waste, the motor 20 rotates in the reverse direction, causing the threaded rod 22 to rotate in the reverse direction. This, in turn, drives the moving plate 23 to move in the reverse direction, causing the protective covers 24 to move closer together until they close. This allows the protective cover 24 to protect the foundry waste during crushing, preventing it from flying out due to excessive crushing force, thus avoiding waste and potential danger. The telescopic rod 26 makes the protective cover 24 more stable when moving via the pulley 25. When the foundry waste enters the crushing chamber 1, the second motor 30 activates its output end, driving the second threaded rod 31 to rotate. The rotation of the second threaded rod 31 drives the force plate 32 to move via the thread, causing the force plate 32 to push the breaker hammers 33 to move inside the crushing chamber 1. This brings the breaker hammers 33 closer together, performing bidirectional crushing of the foundry waste above the support plate 39. The retractable rod 35 makes the movement of the breaker hammers 33 more stable, while the protective cover 24 moves synchronously with the breaker hammers 33. When the breaker hammers 33 move away from each other, the protective covers 24 also move away from each other. At this time, the protective covers 24 drive the pressing inclined plate 36 to move, and the pressing inclined plate 36 will release the pressure on the inclined plate 34. This causes the outer pusher plate 37 to move the inner pusher plate 38 above the support plate 39 due to the elastic force of the spring rod 40. When the breaker hammers 33 move closer to each other, the protective covers 24 move simultaneously. At this time, the protective covers 24 will drive the pressing inclined plate 36 to move, and the pressing inclined plate 36 will drive the outer pusher plate 37 to move through the pressing inclined plate 34. When the outer pusher plate 37 moves, it will drive the inner pusher plate 38 to push the casting waste above the support plate 39 towards the breaker hammers 33, so that the waste can fully enter the working range of the breaker hammers 33 and avoid local incomplete crushing. To address the issue of improving machine efficiency, the inner pusher plate 38, through its own weight, is fully adjusted within the outer pusher plate 37, ensuring continuous contact between the inner pusher plate 38 and the support plate 39. This further enhances the stability of the inner pusher plate 38 in pushing waste material. The fixed tension rod 41 further stabilizes the movement of the outer pusher plate 37 and the inner pusher plate 38. When the second threaded rod 31 rotates, it drives the rotating rod 51 to rotate, which in turn drives the gear 52. The gear 52, through meshing, drives the rack 55 to move. As the rack 55 moves, it drives the lifting wheel 53 to move inside the crushing box 1. The circular telescopic rod 54 further stabilizes the movement of the rack 55. Simultaneously, the movement of the rack 55, through the push-pull rod 56, causes the force application rod 57 to move up and down inside the crushing box 1.When the force bar 57 moves, it drives the lifting support plate 58 to move. The movement of the lifting support plate 58 causes the elastic rod 59 and the impact frame 61 to move together. Simultaneously, the fixed long plate 60 moves due to the compression of the elastic rod 59. When the impact frame 61 moves upward, it drives the impact rod 62 to move, causing the impact rod 62 to strike the bottom of the support plate 39. This separates impurities and other substances from the useful materials in the crushed waste material above the support plate 39, preventing impurities from affecting the machine's crushing operation and causing energy waste. Simultaneously, the movement of the impact frame 61 drives the guide pulley 66 to move inside the lifting rail 64. The guide pull rod 65, through the guide pulley 66... The guide 6 makes the movement of the impact frame 61 more stable. Simultaneously, when the fixed long plate 60 contacts the lifting rail 64, the force rod 57 continues to push the impact frame 61 to move. When the impact frame 61 drives the impact rod 62 to strike the support plate 39, the lifting support plate 58 and the fixed long plate 60 compress the elastic rod 59, causing the elastic rod 59 to buffer the impact rod 62, preventing excessive impact from prolonged operation and affecting normal machine operation. At the same time, when the impact rod 62 strikes the support plate 39, it will cause small impurities that break off above the support plate 39 to fall through the filter holes 50, preventing impurities from accumulating inside the support plate 39 and affecting the machine's normal crushing of casting waste.
