Description

Technical Field

[0001] This invention relates to the field of steel slag conveying, and more specifically to a steel slag conveying equipment. Background Technology

[0002] Steel slag primarily originates from oxides formed after the oxidation of elements contained in molten iron and scrap steel. In the steel production process, steel slag typically undergoes secondary treatment. This treatment process is of great significance, not only enabling the resource utilization of steel slag and effectively reducing the land resources occupied by steel slag stockpiles, but also significantly reducing environmental pollution and greatly improving the utilization rate of steel industry waste, thus possessing both economic and environmental value.

[0003] Among the many stages of secondary steel slag processing, steel slag transportation is particularly crucial. However, traditional steel slag transportation methods are often limited to "point-to-point transport." Under this mode, the steel slag cannot undergo additional processing during transportation and can only be handled by equipment in subsequent stages after transportation is completed. As a result, time is wasted during transportation, leading to the inefficient use of resources.

[0004] Furthermore, in traditional belt conveyors, the slag comes into direct contact with the conveying surface. The slag exiting the steelmaking furnace typically reaches a temperature of around 1500℃-1600℃. Even after initial cooling, the slag temperature remains as high as 200℃-600℃ when conveyed by belt. This is because steel slag has a high specific heat capacity and dissipates heat relatively slowly. Such high temperatures not only accelerate belt aging and damage, shortening its service life, but can also cause safety hazards such as smoke or even fire.

[0005] In recent years, intelligent overhead conveyors have gradually emerged as an advanced automated transportation system. They utilize suspended tracks to suspend hoppers, pallets, and other carriers, enabling the cyclical transport of materials. The tracks are typically designed as closed loops, such as elliptical or circular ones, with motors driving the carriers along a pre-set path. This system can automatically complete material handling at various workstations, including feeding, sorting, and unloading. It boasts significant advantages such as high space utilization, flexible scheduling, and a high degree of automation, and has been widely applied in numerous fields, including automobile manufacturing and food processing.

[0006] Given the numerous advantages of intelligent overhead conveyor systems, their application in steel slag conveying is expected to significantly improve conveying efficiency and effectively save floor space. Therefore, developing a new type of steel slag conveying equipment to better meet current production needs is particularly urgent. Summary of the Invention

[0007] Therefore, it is necessary to provide a steel slag conveying device to address the problems of existing technologies.

[0008] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows: a steel slag conveying device, including a frame and a suspension rail set on the frame, further including a plurality of hoisting support plates equally spaced on the suspension rail, a bearing plate fixedly set symmetrically on each hoisting support plate, a storage bin fixedly set between two bearing plates, a cooling mechanism for cooling the steel slag inside the storage bin, a sealing mechanism for controlling the release of material from the storage bin, and a screening mechanism for screening the steel slag. A discharge port for feeding steel slag is provided on the side of the frame, and the top and bottom of the storage bin are respectively provided with... The feed inlet and discharge outlet are equipped with a cooling mechanism on each storage hopper. The cooling mechanism includes a fan wheel coaxially rotatably mounted on the outer wall of the storage hopper and a rotating output end for driving the fan wheel to rotate. Each discharge outlet is equipped with a sealing mechanism with a sealing output end for controlling the opening and closing of the discharge outlet. The screening mechanism includes a screening frame fixedly mounted on the side of the frame away from the discharge outlet, a first screen plate and a second screen plate arranged sequentially from top to bottom on the screening frame, a storage frame located below the second screen plate, a first conveyor belt located at the bottom of the first screen plate, and a second conveyor belt located at the bottom of the second screen plate.

[0009] Furthermore, the cooling mechanism also includes support plates symmetrically fixed on the upper support plate, a gearbox fixedly connected to the two support plates, a first gear coaxially fixed on the power input shaft of the gearbox, a power gear coaxially fixed on the acceleration output shaft of the gearbox, and a power gear ring coaxially fixed on the impeller. A first rack is fixedly installed on the side of the frame near the discharge port. The first rack is used to mesh with the first gear. The power gear meshes with the power gear ring, which is the rotating output end of the cooling mechanism.

[0010] Furthermore, each storage bin is coaxially fixed with a support ring frame and a vertically positioned disturbance rod inside the storage bin. The bottom end of the disturbance rod is rotatably connected to the support ring frame, and the top end of the disturbance rod passes through the storage bin and is connected to the first gear via a pulley.

[0011] Furthermore, the bottom of the storage hopper is equipped with a funnel-shaped guide cover, and the discharge port is located at the center of the guide cover. The sealing mechanism also includes an oblong box fixedly installed at the bottom of the discharge port and a sealing circular plate slidably installed in the oblong box. The oblong box has a discharge port, which is coaxial with the discharge port. The diameter of the sealing circular plate is slightly larger than the diameter of the discharge port, and the sealing circular plate is connected to the sealing output end.

[0012] Furthermore, the sealing mechanism also includes a U-shaped sliding frame slidably mounted on the outer wall of the waist-shaped box, a connecting rod fixedly connected to the sealing circular plate, an actuating rack fixedly mounted on the U-shaped sliding frame, a limiting support plate fixedly mounted on the bottom of the waist-shaped box, an actuating shaft rotatably mounted on the limiting support plate, a second gear coaxially fixedly mounted on the end of the actuating shaft, an actuating sleeve coaxially fixedly mounted in the middle of the actuating shaft, and an actuating toothed ring connected to the actuating sleeve in a transmission. A second rack for meshing with the second gear is fixedly mounted on the screening frame. The actuating toothed ring meshes with the actuating rack, and the connecting rod is fixedly connected to the U-shaped sliding frame.

[0013] Furthermore, the connecting rod is the sealing output end of the sealing mechanism.

[0014] Furthermore, the trigger sleeve is provided with several elastic columns arranged in a ring at equal intervals, the inner wall of the trigger toothed ring is provided with several limiting grooves arranged in a ring at equal intervals, a carrier box is fixedly set at the bottom of the waist-shaped box, and a coil spring is set in the carrier box. One end of the coil spring is fixedly connected to the trigger shaft, and the other end is fixedly connected to the inner wall of the carrier box. The trigger shaft is rotatably connected to the carrier box. A guide slope is provided on one side of the limiting groove, and the head of the elastic column is stuck in the limiting groove under the elastic action.

[0015] Furthermore, a material-laying square tube is fixedly installed at the bottom of each waist-shaped box, and a coil spring is fixedly installed inside the material-laying square tube, which is located below the material outlet.

[0016] Furthermore, each hoisting support plate is equipped with a striking mechanism, which includes a mounting plate fixedly mounted on the bearing plate, a limiting sleeve fixedly mounted on the mounting plate, a bearing shaft rotatably mounted in the limiting sleeve via a torsion spring, a striking rod fixedly mounted on the bearing shaft, a crank rod with one end coaxially fixed to the bearing shaft, a connecting shaft rotatably mounted on the mounting plate, a crank gear coaxially fixedly mounted on the connecting shaft, a power shaft rotatably mounted on the hoisting support plate, and a third gear coaxially fixedly mounted on the power shaft. A third rack for meshing with the third gear is fixedly mounted on the frame. Under the action of the torsion spring, the striking rod always abuts against the guide cover, and the other end of the crank rod abuts against the crank gear.

[0017] Furthermore, the screening mechanism also includes two symmetrically arranged connecting horizontal plates elastically mounted on the screening frame, an abutting ridge fixedly mounted on the connecting horizontal plate near the frame, a drive chain mounted at the bottom of the frame, a bearing horizontal plate fixedly mounted on the screening frame, a drive shaft rotatably mounted on the bearing horizontal plate, a cam coaxially fixedly mounted on one end of the drive shaft, and a vibrating gear at the other end. The cam abuts against the abutting ridge. A lifting rod is fixedly mounted at the bottom of each lifting support plate. All lifting rods are fixedly connected to the drive chain, and the drive chain meshes with the vibrating gear.

[0018] The beneficial effects of this invention compared to the prior art are:

[0019] Firstly, the cooling mechanism of this steel slag conveying equipment is ingeniously designed. Through the meshing of the first rack and the first gear, the gearbox accelerates the rotation of the impeller, quickly removing heat from the storage bin and cooling the steel slag. Simultaneously, the agitator crank, driven by the first gear, tumbles the steel slag, ensuring uniform cooling within the storage bin. This provides steel slag at a suitable temperature for subsequent processing, improving production quality.

[0020] Secondly, the sealing mechanism can precisely control the opening and closing of the discharge port. When the storage hopper moves to the screening frame, the second rack and the second gear work together to automatically open the discharge port. In addition, the striking mechanism operates synchronously, and the third rack and the third gear cause the striking rod to reciprocate to strike the guide bottom cover, effectively preventing steel slag from accumulating in the guide bottom cover, ensuring smooth discharge, and improving conveying efficiency.

[0021] Thirdly, the screening mechanism, through the coordinated operation of components such as a chain, vibrating gears, and cams, causes the connecting horizontal plate to drive the first and second screen plates to vibrate. This design enhances the screening effect, ensuring the effective separation of steel slag of different particle sizes, facilitating subsequent targeted processing, improving the utilization rate of steel slag resources, and reducing waste.

[0039] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0040] refer to Figures 1 to 16 :

[0041] A steel slag conveying device includes a frame 1 and a suspension rail 2 mounted on the frame 1. It also includes several hoisting support plates 3 evenly spaced on the suspension rail 2, bearing plates 4 symmetrically fixed on each hoisting support plate 3, a storage bin 5 fixed between two bearing plates 4, a cooling mechanism for cooling the steel slag inside the storage bin 5, a sealing mechanism for controlling the release of material from the storage bin 5, and a screening mechanism for screening the steel slag. A discharge port 37 for feeding steel slag is provided on the side of the frame 1. An inlet 6 and a discharge port 26 are respectively provided at the top and bottom of the storage bin 5. Each storage bin 5 is equipped with... The cooling mechanism includes a fan 38 coaxially rotatably mounted on the outer wall of the storage tank 5 and a rotating output end for driving the fan 38 to rotate. Each discharge port 26 is equipped with a sealing mechanism, which has a sealing output end for controlling the opening and closing of the discharge port 26. The screening mechanism includes a screening frame 47 fixedly mounted on the side of the frame 1 away from the discharge port 37, a first screen plate 50 and a second screen plate 52 arranged sequentially from top to bottom on the screening frame 47, a storage frame 61 arranged below the second screen plate 52, a first conveyor belt 51 arranged at the bottom of the first screen plate 50, and a second conveyor belt 53 arranged at the bottom of the second screen plate 52.

[0042] It should be noted that the steel slag fed through the discharge port 37 is steel slag that has been pre-cooled to a temperature of 200-600 degrees Celsius. Position sensors are installed at both the discharge port 37 and the inlet 6. That is, during the circulation of the storage bin 5, steel slag is fed through the discharge port 37 once after passing through one storage bin 5. In addition, the suspension track 2 is a mature existing technology, so it will not be described in detail here. It can be started and stopped intermittently to complete the conveying work. During operation, steel slag is fed from the discharge port 37 to the feed port 6. The suspended track 2 then moves the hoisting support plate 3, causing the storage bin 5 containing the steel slag to move. The cooling mechanism then operates, rotating the output end to drive the impeller 38 to rotate. The impeller 38 generates airflow, accelerating the removal of heat from the storage bin 5, thus cooling the steel slag inside. Once the storage bin 5 reaches the screening frame 47, the sealing mechanism opens the discharge port 26. At this point, the steel slag has been cooled and falls onto the first screen plate 50. Under the screening of the first screen plate 50 and the second screen plate 52, larger steel slag particles are conveyed away by the first conveyor belt 51, medium-sized steel slag particles are conveyed away by the second conveyor belt 53, and smaller steel slag particles fall from the second screen plate 52 into the storage frame 61. This screening facilitates subsequent processing.

[0043] To demonstrate the detailed structure of the cooling mechanism, the following features were specifically included:

[0044] The cooling mechanism also includes a support plate 40 fixedly mounted symmetrically on the upper support plate 4, a gearbox 41 fixedly connected to the two support plates 40, a first gear 42 coaxially fixedly mounted on the power input shaft of the gearbox 41, a power gear 43 coaxially fixedly mounted on the acceleration output shaft of the gearbox 41, and a power gear ring 44 coaxially fixedly mounted on the impeller 38. A first rack 39 is fixedly mounted on the side of the frame 1 near the discharge port 37. The first rack 39 is used to mesh with the first gear 42. The power gear 43 meshes with the power gear ring 44. The power gear ring 44 is the rotating output end of the cooling mechanism.

[0045] When the device is running, the first gear 42 meshes with the first rack 39. The rotation of the first gear 42 is accelerated by the gearbox 41, which drives the power gear 43 to rotate. The rotation of the power gear 43 then drives the power gear ring 44 to rotate, which in turn drives the impeller 38 to rotate. Thus, the rotation of the impeller 38 generates airflow, which continuously removes the heat from the storage tank 5, thereby achieving the cooling treatment of the steel slag.

[0046] To prevent uneven cooling of the steel slag within the storage bin 5, the following features are specifically included:

[0047] Each storage bin 5 is coaxially fixed with a support ring frame 45 and a disturbance rod 46 that is vertically installed inside the storage bin 5. The bottom end of the disturbance rod 46 is rotatably connected to the support ring frame 45, and the top end of the disturbance rod 46 passes through the storage bin 5 and is connected to the first gear 42 via a pulley.

[0048] During operation, the rotation of the first gear 42 also drives the agitator crank 46 to rotate via the pulley. The rotation of the agitator crank 46 continuously agitates the slag, thereby ensuring that the slag in the storage bin 5 can be continuously agitated and heat dissipated evenly, facilitating cooling. It should be noted that the rotational speed of the first gear 42 meshing with the first rack 39 is relatively low, and the crank 46 is helical. Its rotation is for the purpose of helically lifting the slag, agitating the slag in this way, not for breaking the slag. Therefore, the crank 46 does not experience significant resistance when agitating the slag.

[0049] To demonstrate the detailed structure of the blocking mechanism, the following features were specifically included:

[0050] The bottom of the storage tank 5 is provided with a funnel-shaped guide cover 7, and the discharge port 26 is opened at the center of the guide cover 7. The sealing mechanism also includes an waist-shaped box 8 fixedly set at the bottom of the discharge port 26 and a sealing circular plate 10 slidably set in the waist-shaped box 8. The waist-shaped box 8 is provided with a discharge port 9, which is coaxial with the discharge port 26. The diameter of the sealing circular plate 10 is slightly larger than the diameter of the discharge port 9, and the sealing circular plate 10 is connected to the sealing output end.

[0051] When it is necessary to open the discharge port 26, the blocking output end drives the blocking circular plate 10 to open the discharge port 9, and then the steel slag can be discharged through the discharge port 9 and fall onto the first screen plate 50. In addition, the funnel shape of the guide bottom cover 7 facilitates the smooth discharge of steel slag.

[0052] To demonstrate the detailed structure of the blocking mechanism's output end, the following features are specifically included:

[0053] The sealing mechanism also includes a U-shaped sliding frame 12 slidably mounted on the outer wall of the waist-shaped box 8, a connecting rod 11 fixedly connected to the sealing circular plate 10, an actuating rack 13 fixedly mounted on the U-shaped sliding frame 12, a limiting support plate 14 fixedly mounted at the bottom of the waist-shaped box 8, an actuating shaft 15 rotatably mounted on the limiting support plate 14, a second gear 16 coaxially fixedly mounted at the end of the actuating shaft 15, an actuating sleeve 17 coaxially fixedly mounted in the middle of the actuating shaft 15, and an actuating toothed ring 19 that is connected to the actuating sleeve 17 in a transmission. A second rack 48 for meshing with the second gear 16 is fixedly mounted on the screening frame 47. The actuating toothed ring 19 meshes with the actuating rack 13. The connecting rod 11 is fixedly connected to the U-shaped sliding frame 12.

[0054] Connecting rod 11 is the blocking output end of the blocking mechanism.

[0055] During operation, as the storage tank 5 moves, the second gear 16 meshes with the second rack 48. The rotation of the second gear 16 drives the actuating shaft 15 to rotate. The rotation of the actuating shaft 15 then drives the actuating gear ring 19 to rotate through the actuating sleeve 17. The rotation of the actuating gear ring 19 meshes with the actuating rack 13, which in turn causes the actuating rack 13 to drive the U-shaped sliding frame 12 to move. Then, the U-shaped sliding frame 12 drives the sealing circular plate 10 to open the discharge port 9 through the connecting rod 11.

[0056] To prevent the second gear 16 from still meshing with the second rack 48 after the sealing plate 10 opens the discharge port 9, thus damaging the equipment, the following features are specifically provided:

[0057] The trigger sleeve 17 is provided with several elastic columns 18 arranged in a ring at equal intervals, the inner wall of the trigger toothed ring 19 is provided with several limiting grooves 20 arranged in a ring at equal intervals, the support box 22 is fixedly set at the bottom of the waist-shaped box 8 and the coil spring 23 is set in the support box 22. One end of the coil spring 23 is fixedly connected to the trigger shaft 15 and the other end is fixedly connected to the inner wall of the support box 22. The trigger shaft 15 is rotatably connected to the support box 22. A guide slope 21 is provided on one side of the limiting groove 20. The column head of the elastic column 18 is stuck in the limiting groove 20 under the elastic action.

[0058] When the actuating shaft 15 rotates, it drives the actuating sleeve 17 to rotate, which in turn drives all the elastic columns 18 to rotate. The elastic columns 18 then drive the actuating gear ring 19 to rotate synchronously through the column heads that are locked in the limiting groove 20, waiting for the discharge port 9 to fully open. At this time, the actuating sleeve 17 continues to rotate, but the actuating gear ring 19 has already moved to the limit position of the actuating rack 13. Therefore, the actuating gear ring 19 is in a fixed state relative to the actuating sleeve 17. As the actuating sleeve 17 rotates, the elastic columns 18 abut against the guide slope 21, and then the column heads of the elastic columns 18 retract. "Slippage" occurs between the actuating sleeve 17 and the actuating gear ring 19, thereby ensuring that the equipment can continue to operate normally after the discharge port 9 is opened. This provides the equipment with some fault tolerance and prevents the discharge port 9 from being opened but the second gear 16 has not yet passed the length of the second rack 48, thus avoiding jamming and damage to the equipment.

[0059] To ensure that the steel slag falling from the discharge port 26 is evenly spread on the first screen plate 50, the following features are specifically designed:

[0060] Each waist-shaped box 8 has a material-laying square tube 24 fixedly installed at its bottom, and a material-blocking plate 25 fixedly installed inside the material-laying square tube 24. The material-laying square tube 24 is located below the material outlet 9.

[0061] During the rotation of the actuating shaft 15, the rotation of the actuating shaft 15 always applies torque to the coil spring 23. After the second gear 16 passes the second rack 48, the coil spring 23 releases the torque and drives the actuating shaft 15 to rotate in the opposite direction. The reverse rotation of the actuating shaft 15 drives the actuating sleeve 17 to rotate in the opposite direction. Since the guide slope 21 is provided at the limiting groove 20, when the actuating sleeve 17 starts to rotate in the opposite direction, the elastic column 18 will slide into the guide slope 21 and then get stuck in the limiting groove 20. Then the actuating sleeve 17 drives the actuating toothed ring 19 to rotate in the opposite direction. The reverse rotation of the actuating toothed ring 19 meshes with the actuating rack 13 and moves. Then, through the U-shaped sliding frame 12 and the connecting rod 11, the sealing circular plate 10 blocks the discharge port 9. The setting of the baffle plate 25 can disperse the steel slag and make it easier to spread evenly on the first screen plate 50.

[0062] To prevent steel slag from accumulating on the guide cover 7, the following features are specifically designed:

[0063] Each hoisting support plate 3 is equipped with a striking mechanism, which includes a mounting plate 28 fixedly mounted on the bearing plate 4, a limiting sleeve 29 fixedly mounted on the mounting plate 28, a bearing shaft 30 rotatably mounted in the limiting sleeve 29 via a torsion spring, a striking rod 31 fixedly mounted on the bearing shaft 30, a pulsating crank 32 coaxially fixed to the bearing shaft 30 at one end, a connecting shaft 33 rotatably mounted on the mounting plate 28, a pulsating gear 34 coaxially fixed on the connecting shaft 33, a power shaft 35 rotatably mounted on the hoisting support plate 3, and a third gear 36 coaxially fixed on the power shaft 35. A third rack 27 for meshing with the third gear 36 is fixedly mounted on the frame 1. Under the action of the torsion spring, the striking rod 31 always abuts against the guide cover 7, and the other end of the pulsating crank 32 abuts against the pulsating gear 34.

[0064] It should be noted that when the second rack 48 meshes with a second gear 16, the third rack 27 also meshes with a third gear 36. During operation, the third gear 36 meshes with the third rack 27, and the rotation of the third gear 36 drives the power shaft 35 to rotate. The rotation of the power shaft 35 is transmitted through the bevel gear to drive the connecting shaft 33 to rotate. The rotation of the connecting shaft 33 drives the actuating gear 34 to rotate. The rotation of the actuating gear 34 continuously drives the actuating crank 32 to swing. The swing of the actuating crank 32 drives the bearing shaft 30 to rotate. The rotation of the bearing shaft 30 overcomes the torsion spring torque and drives the striking rod 31 away from the guide bottom cover 7. When one tooth of the actuating gear 34 passes one end of the actuating crank 32, the torsion spring releases the torque and drives the bearing shaft 30 to rotate in the opposite direction, thereby driving the striking rod 31 to strike the guide bottom cover 7. This process repeats, and the striking rod 31 repeatedly strikes the guide bottom cover 7 to create vibration, preventing the accumulation of steel slag.

[0065] To ensure better screening performance of the first sieve plate 50 and the second sieve plate 52, the following features are specifically designed:

[0066] The screening mechanism also includes two symmetrically arranged connecting horizontal plates 49 elastically set on the screening frame 47, abutting protrusions 54 fixedly set on the connecting horizontal plates 49 near the frame 1, a toggle chain 59 set at the bottom of the frame 1, a bearing horizontal plate 55 fixedly set on the screening frame 47, a toggle shaft 56 rotatably set on the bearing horizontal plate 55, a cam 58 coaxially fixedly set at one end of the toggle shaft 56 and a toggle gear 34 at the other end, the cam 58 abutting against the abutting protrusions 54, and a lifting rod 60 fixedly set at the bottom of each lifting support plate 3, all lifting rods 60 being fixedly connected to the toggle chain 59, and the toggle chain 59 meshing with the vibrating gear 57.

[0067] During operation, the hoisting support plate 3 drives the hoisting rod 60 to rotate, which in turn drives the actuating chain 59 to rotate continuously. The rotation of the actuating chain 59 meshes with the vibrating gear 57, causing the vibrating gear 57 to rotate. The rotation of the vibrating gear 57 drives the actuating shaft 56 to rotate, which in turn drives the cam 58 to rotate. The rotation of the cam 58 continuously contacts and abuts the protrusion 54, causing the connecting horizontal plate 49 to vibrate up and down on the screening frame 47. This causes the first screen plate 50 and the second screen plate 52 to vibrate, enhancing the screening effect.

[0068] The working principle of this device is as follows: When the steel slag conveying equipment is running, the steel slag, which has been initially cooled to 200-600 degrees, is fed into the inlet 6 of the storage tank 5 from the discharge port 37. The suspension rail 2 drives the hoisting support plate 3 and the storage tank 5 to move.

[0069] During operation, the first rack 39 on the frame 1 near the discharge port 37 meshes with the first gear 42 on the power input shaft of the gearbox 41 in the cooling mechanism, driving the power gear 43 to rotate. This, in turn, causes the power gear ring 44 to drive the fan wheel 38 to rotate, generating airflow to cool the steel slag inside the storage bin 5. Simultaneously, the first gear 42 drives the agitator crank 46 inside the storage bin 5 to rotate via a pulley, agitating the steel slag to ensure uniform cooling.

[0070] When the storage hopper 5 moves to the screening frame 47, the second rack 48 on the screening frame 47 meshes with the second gear 16 at the end of the trigger shaft 15 rotatably mounted on the limit support plate 14 in the sealing mechanism, causing the trigger shaft 15 to rotate. This causes the trigger gear ring 19 to rotate through the trigger sleeve 17. The trigger gear ring 19 meshes with the trigger rack 13, driving the U-shaped sliding frame and connecting rod 11, causing the sealing circular plate 10 to open the discharge port 26. The steel slag falls onto the first screen plate 50 through the guide bottom cover 7 and the discharge port 9.

[0071] At this time, the third gear 36, which operates synchronously with the second gear 16, meshes with the third rack 27 on the frame 1, driving the power shaft 35 to rotate. Through the bevel gear, the actuating gear 34 on the connecting shaft 33 rotates, driving the crank rod 32 to drive the striking rod 31 to strike the guide cover 7, preventing the accumulation of steel slag.

[0072] Steel slag is screened on the first screen plate 50 and the second screen plate 52. Larger particles are carried away by the first conveyor belt 51, medium-sized particles are carried away by the second conveyor belt 53, and smaller particles fall into the storage frame 61. At the same time, the lifting support plate 3 drives the lifting rod 60 to rotate the actuating chain 59, which meshes with the actuating gear 34, driving the cam 58 to rotate, causing the connecting cross plate 49 to vibrate, thereby enhancing the screening effect of the first screen plate 50 and the second screen plate 52.

[0073] After the steel slag is discharged, the second gear 16 passes the length of the second rack 48, and the coil spring 23 releases torque to drive the trigger shaft 15 to rotate in the opposite direction. The reverse rotation of the trigger shaft 15 drives the trigger sleeve 17 to rotate in the opposite direction. Since the guide slope 21 is set at the limit groove 20, when the trigger sleeve 17 starts to rotate in the opposite direction, the elastic column 18 will slide into the guide slope 21 and then get stuck in the limit groove 20. Then the trigger sleeve 17 drives the trigger tooth ring 19 to rotate in the opposite direction. The reverse rotation of the trigger tooth ring 19 meshes with the trigger rack 13 to move, and then drives the sealing round plate 10 to block the discharge port 9 through the U-shaped sliding frame 12 and the connecting rod 11.

[0074] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
