[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand: the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 4 As shown, the present invention provides a technical solution: a ladle sand filling equipment, comprising a floor 1, a placing table 2 is symmetrically fixedly installed directly above the floor 1, a ladle box 3 is placed directly above the two placing tables 2, the inner wall of the ladle box 3 is coated with silicone glue, a support frame 4 is fixedly connected directly above the floor 1, an outer ring auxiliary plate 5 is fixedly connected to the top of the support frame 4, a feeding funnel 6 is fixedly connected to the inner side of the outer ring auxiliary plate 5, a feeding pipe 7 is fixedly connected to the bottom of the feeding funnel 6, an opening and closing component is arranged inside the feeding pipe 7, the opening and closing component is used to control the opening and closing of the feeding pipe 7 for unloading, the inner wall of the ladle box 3 is slidably connected to an extrusion top plate 8, the outer wall of the extrusion top plate 8 is a smooth coating surface and a jacking component is arranged on the top, and the jacking component is used to drive the opening and closing component to move.

[0035] During operation: when the existing ladle sand filling equipment is performing sand filling operations, the prefabricated refractory sand is transported to the inside of the ladle through the sand filling equipment and evenly coated on the inner wall of the ladle, wherein the sand is evenly covered on the inner wall of the ladle by spraying or showering. However, since the sand is sprayed by spraying, the sand attached to the inner wall of the ladle is not firm, resulting in the detachment of the refractory layer, the decline of molten steel quality, the increase of maintenance costs, safety hazards and production interruptions, which seriously affect the service life and production efficiency of the ladle. Through the embodiment of the present scheme, when it is used specifically, the inner wall of the ladle that needs to be filled with sand is coated with silicone glue in advance and placed directly above the placement table 2. At this time, the extrusion top plate 8 is adjusted to the inner wall of the ladle box 3, and then the opening and closing assembly is opened. The sand will slowly enter the interior of the ladle box 3 through the feeding funnel 6 and the feeding pipe 7. When the sand in the ladle box 3 gradually increases, the sand will cause the extrusion top plate 8 to rise. When the extrusion top plate 8 rises, it will The lifting assembly is driven to move. When the extrusion top plate 8 is lifted and separated from the interior of the ladle box 3, the opening and closing assembly is just driven to complete the movement, and the outlet of the feed pipe 7 is blocked to complete the feeding. At this time, the interior of the ladle box 3 is just filled with sand. Since the interior of the ladle box 3 is coated with silicone glue, the sand in contact with the inner wall of the ladle box 3 will be tightly adhered, and then the excess sand in the ladle box 3 is discharged, and the excess sand is transported to the feed funnel 6 for recycling. Through the above embodiment, by first coating the inner wall of the ladle with glue, and then filling the inner wall of the ladle with sand, the sand in contact with the inner wall of the ladle will be adhered, and the excess sand is discharged. Compared with the method of spraying sand, this method makes the sand filled on the inner wall of the ladle more complete and firm, forming a more uniform and full covering layer, and can more accurately control the amount of sand, and can also avoid the waste or excessive use of sand that may be generated during spraying, thereby saving costs.

[0036] like Figures 2 to 4 As shown, the opening and closing assembly includes a disc valve 15, which can be completely fitted with the inner wall of the feed pipe 7, the outer wall of the disc valve 15 is fixedly connected to a rotating rod 14, both ends of the rotating rod 14 are fixedly connected to a gear 13, the outer wall of the rotating rod 14 is symmetrically rotatably connected to a clamping member 16, and the tops of the two clamping members 16 are fixedly connected to the bottom of the outer ring auxiliary plate 5.

[0037] During operation: when the amount of sand in the ladle box 3 gradually increases, the sand will cause the extrusion top plate 8 to rise. When the extrusion top plate 8 rises, it will drive the two gears 13 to rotate 90 degrees. When the gear 13 rotates, it will drive the disc valve 15 to rotate 90 degrees through the rotating rod 14, so that the disc valve 15 will be completely fitted with the inner wall of the feed pipe 7, completing the blockage and stopping the material discharge, and the rotating rod 14 is fixed in position by the clamping member 16. Through the above embodiment, in the process of filling the ladle box 3 with sand, when the sand just fills the inside of the ladle box 3, the feed pipe 7 stops discharging the material, thereby realizing precise control of the amount of sand during the filling process to avoid excessive or insufficient sand.

[0038] like Figure 5 to Figure 6 As shown, the lifting assembly includes two side ear plates 9, and the two side ear plates 9 are fixedly connected to the outer wall of the extrusion top plate 8. The tops of the two side ear plates 9 are fixedly connected with a rack plate 10, and the teeth of the rack plate 10 are meshed with the teeth of the gear 13. The number of teeth of the rack plate 10 is half of that of the gear 13. The tops of the two rack plates 10 are fixedly connected with a push rod 11, and the outer walls of the two push rods 11 are plugged into the inner wall of the outer ring auxiliary plate 5. The tops of the two push rods 11 are fixedly connected with a truncated cone block 17, and a positioning assembly is arranged above the truncated cone block 17, and the positioning assembly is used to position the rising truncated cone block 17.

[0039] During operation: when the sand material lifts the extrusion top plate 8, it will drive the rack plate 10 to rise. When the rack plate 10 rises, it will drive the gear 13 to rotate 90 degrees, and the rise of the rack plate 10 will also drive the push rod 11 and the truncated cone block 17 to rise. When the rack plate 10 rises, the ladle box 3 is filled with sand material, and then the excess sand material needs to be discharged. When the sand material is discharged, in order to prevent the position of the extrusion top plate 8 from entering the interior of the ladle, the truncated cone block 17 rises. During the process, the locking component will be triggered, so that the position of the truncated cone block 17 will not automatically drop. After the sand is discharged and the next ladle is placed, the locking component cancels the restriction on the truncated cone block 17. At this time, the truncated cone block 17 will drop and drive the rack plate 10 and the extrusion top plate 8 to drop. At this time, the extrusion top plate 8 will re-enter the interior of the ladle box 3 and the rack plate 10 will drive the gear 13 to rotate 90 degrees again, so that the disc valve 15 will cancel the blockage and discharge the material. This process is repeated to realize the sand filling process of the ladle cycle.

[0040] like Figures 4 to 6 As shown, a return spring 12 is disposed outside the two push rods 11, one end of the two return springs 12 is fixedly connected to the top of the two rack plates 10 respectively, and the other end of the two return springs 12 is fixedly connected to the bottom of the outer ring auxiliary plate 5.

[0041] During operation: through the reset spring 12 arranged between the outer ring auxiliary plate 5 and the rack plate 10, the positioning assembly cancels the restriction on the truncated cone block 17. Due to the action of the reset spring 12, the push rod 11, the rack plate 10 and the extrusion top plate 8 can be reset and lowered.

[0042] like Figures 5 to 7 As shown, the positioning assembly includes two hollow seats 18, and the two hollow seats 18 are fixedly installed directly above the outer ring auxiliary plate 5. The two truncated cone blocks 17 are respectively located inside the two hollow seats 18. The outer wall of the outer ring auxiliary plate 5 is symmetrically fixedly connected with the mounting plate 22. The inner walls of the two mounting plates 22 are plugged with push rods 21. One ends of the two push rods 21 are fixedly connected with extrusion blocks 19. Reset springs 20 are fixedly connected between the two extrusion blocks 19 and one side of the mounting plate 22. The other ends of the two push rods 21 are fixedly connected with truncated cone blocks 23.

[0043] During operation: when the truncated cone block 17 rises, it will slowly squeeze the position of the extrusion block 19 and the reset spring 20, so that the extrusion block 19 moves outward through the push rod 21. When the extrusion is completed, the truncated cone block 17 is at the highest point. At this time, the extrusion block 19 will be located at the bottom of the truncated cone block 17 and reset by the reset spring 20, blocking the bottom of the truncated cone block 17, so that the truncated cone block 17 cannot descend. Through the above embodiment, the position of the rack plate 10 and the extrusion top plate 8 after the rise is fixed by the truncated cone block 17, so that when the sand is discharged and the next ladle box 3 is replaced, the rack plate 10 and the extrusion top plate 8 will not descend to affect the work process.

[0044] like Figure 6 to Figure 7 As shown, a handle bar 25 is fixedly connected between the outer walls of the two truncated cone blocks 23, a fixing plate 24 is fixedly connected to one side of the two mounting plates 22, and the bottoms of the two extrusion blocks 19 are slidably connected to the two fixing plates 24 respectively.

[0045] During operation: after the sand is discharged and a new ladle box 3 is replaced, the handle rod 25 is pulled outward, and the extrusion block 19 will be pulled through the truncated cone block 23 and the push rod 21, and the extrusion block 19 will move on the upper surface of the fixed plate 24. At this time, the bottom of the truncated cone block 17 will not be blocked by the extrusion block 19, and the truncated cone block 17 will descend, and the rack plate 10 and the extrusion top plate 8 will be driven to descend through the push rod 11. At this time, the rack plate 10 will drive the gear 13 to rotate 90 degrees again through the gear 13, so that the disc valve 15 is unblocked for unloading, and the extrusion top plate 8 will re-enter the interior of the ladle box 3. Through the above embodiment, the effect of being able to circulate sand in the ladle is achieved.

[0046] like Figures 8 to 9 As shown, a disc valve 2 32 is provided at the opening at the bottom of the ladle box 3, and a rotating rod 2 31 is fixedly connected to the outer wall of the disc valve 2 32, and a clamping member 2 33 is symmetrically rotatably connected to the outer wall of the rotating rod 2 31, and the two clamping members 2 33 are fixedly installed between one side of the two placement platforms 2, and one end of the rotating rod 2 31 is fixedly connected to a gear 2 30, and a driving assembly is provided above the gear 2 30, and the driving assembly is used to drive the gear 2 30 to rotate 90 degrees.

[0047] During operation: when the truncated cone block 17 rises to the highest point, the sand filling work is completed. At this time, the truncated cone block 17 will start the driving assembly, which will drive the gear 2 30 to rotate 90 degrees. When the gear 2 30 rotates 90 degrees, the disc valve 2 32 will be driven to rotate 90 degrees through the rotating rod 2 31, so that the outlet of the ladle box 3 is not blocked, so that the excess sand added to the inside of the ladle box 3 can be discharged, so that the excess sand can still be used.

[0048] like Figures 8 to 9 As shown, the drive assembly includes a control button 26, which is fixedly installed on the inner side of the top of the hollow seat 18. The outer wall of the extrusion top plate 8 is fixedly connected to an auxiliary platform 27, and the bottom of the auxiliary platform 27 is fixedly connected to an electronic telescopic rod 28. The control button 26 is used to control the extension and retraction of a rack plate 29, and the bottom of the electronic telescopic rod 28 is fixedly connected to a rack plate 29. The teeth of the rack plate 29 are meshed with the teeth of a gear 2 30, and the number of teeth of the rack plate 29 is half of that of the gear 2 30.

[0049] During operation: when the truncated cone block 17 rises to the highest point, it touches the control button 26. When the control button 26 is pressed, the electronic telescopic rod 28 is controlled to move downward, and the rack plate 29 is meshed with the gear 2 30 to make the gear 2 30 rotate 90 degrees. When the gear 2 30 rotates 90 degrees, the disc valve 2 32 is rotated 90 degrees, so that the excess sand can be discharged.

[0050] like Figures 9 and 10 As shown, a collection box 34 is arranged directly above the floor 1, and the collection box 34 is located directly below the opening of the ladle box 3. Slide plates 35 are fixedly connected to both sides of the inner wall of the collection box 34. A material conveying assembly is arranged above the collection box 34, and the material conveying assembly is used to drive excess sand material into the feed funnel 6.

[0051] During operation, the excess sand material can fall into the aggregate box 34 and can fall to the center of the aggregate box 34 through the slide plate 35. Then, the feeding assembly is started so that the excess sand material can enter the feed hopper 6, thereby achieving the effect of recycling the sand material.

[0052] like Figures 9 and 10As shown, the feeding assembly includes a clamping ring 36, which is fixedly installed just above the floor 1, and a barrel 37 is fixedly connected to the inner side of the clamping ring 36, and the opening of the barrel 37 fits in the notch of the feed funnel 6, and a motor 38 is fixedly connected to one side of the hollow seat 18, and the output shaft of the motor 38 is fixedly connected to a conveying rod 39, and an auger blade 40 is fixedly connected to the outer wall of the conveying rod 39, and the conveying rod 39 and the auger blade 40 are both located inside the barrel 37.

[0053] During operation: after placing the ladle box 3, start the motor 38, and its output shaft will drive the auger blade 40 to rotate through the conveying rod 39, so that the sand in the collection box 34 can be conveyed to the feeding funnel 6 through the auger blade 40, and when the sand is used up, sand can be directly added to the collection box 34 to realize the conveying of the sand.

[0054] Working process: First, the inner wall of the ladle that needs to be filled with sand is coated with silicone glue in advance and placed directly above the placement table 2. At this time, the extrusion top plate 8 is adjusted to the inner wall of the ladle box 3, and then the opening and closing assembly is opened. The sand material will slowly enter the interior of the ladle box 3 through the feeding funnel 6 and the feeding pipe 7. When the sand material in the ladle box 3 gradually increases, the sand material will cause the extrusion top plate 8 to rise. When the extrusion top plate 8 rises, it will drive the two gears 13 to rotate 90 degrees. When the gear 13 rotates, it will drive the disc valve 15 to rotate 90 degrees through the rotating rod 14, so that the disc valve 15 will be completely fitted with the inner wall of the feeding pipe 7, completing the blockage and stopping the feeding. At this time, the interior of the ladle box 3 is just filled with sand material. Since the interior of the ladle box 3 is coated with silicone glue, the sand material in contact with the inner wall of the ladle box 3 will be tightly adhered.

[0055] Secondly, when the sand material lifts the extrusion top plate 8, it will drive the rack plate 10 to rise. When the rack plate 10 rises, it will drive the gear 13 to rotate 90 degrees, and the rise of the rack plate 10 will also drive the push rod 11 and the truncated cone block 17 to rise. When the rack plate 10 is raised, the ladle box 3 is filled with sand material, and then the excess sand material needs to be discharged. When the sand material is discharged, in order to prevent the position of the extrusion top plate 8 from entering the interior of the ladle, when the truncated cone block 17 rises, it will slowly squeeze the position of the extrusion block 19 and The extrusion reset spring 20 causes the extrusion block 19 to move outward through the push rod 21. When the extrusion is completed, the truncated cone block 17 is at the highest point. At this time, the extrusion block 19 will be located at the bottom of the truncated cone block 17 and reset by the reset spring 20, blocking the bottom of the truncated cone block 17 so that the truncated cone block 17 cannot fall. The truncated cone block 17 is used to fix the positions of the rack plate 10 and the extrusion top plate 8 after they are raised, so that when the sand is discharged and the next ladle box 3 is replaced, the rack plate 10 and the extrusion top plate 8 will not fall, thereby affecting the work flow.

[0056] Then, when the sand material is discharged and a new ladle box 3 is replaced, the handle rod 25 is pulled outward, and the extrusion block 19 will be pulled through the truncated cone block 23 and the push rod 21, and the extrusion block 19 will move on the upper surface of the fixed plate 24. At this time, the bottom of the truncated cone block 17 will not be blocked by the extrusion block 19, and the truncated cone block 17 will descend, and the rack plate 10 and the extrusion top plate 8 will be driven to descend through the push rod 11. At this time, the rack plate 10 will drive the gear 13 to rotate 90 degrees again through the gear 13, so that the disc valve 15 is unblocked for unloading, and the extrusion top plate 8 will re-enter the interior of the ladle box 3.

[0057] Finally, when the truncated cone block 17 rises to the highest point, it touches the control button 26. When the control button 26 is pressed, the electronic telescopic rod 28 is controlled to move downward, and the rack plate 29 is meshed with the gear 2 30 to make the gear 2 30 rotate 90 degrees. When the gear 2 30 rotates 90 degrees, the disc valve 2 32 is rotated 90 degrees. When the gear 2 30 rotates 90 degrees, the disc valve 2 32 is driven to rotate 90 degrees through the rotating rod 2 31, so that there is no outlet of the ladle box 3. The blockage allows the excess sand added to the inside of the ladle box 3 to be discharged, and the discharged excess sand can fall into the aggregate box 34, and can fall to the center of the aggregate box 34 through the landslide plate 35. The motor 38 is started, and its output shaft will drive the auger blade 40 to rotate through the conveying rod 39, so that the sand in the aggregate box 34 can be conveyed to the feed funnel 6 through the auger blade 40, and when the sand is used up, the sand can be directly added to the aggregate box 34 to realize the conveying of the sand.
