Description

[0002] Limestone powder is made by grinding limestone, and its main component is calcium carbonate. It has high whiteness and stable chemical properties, and is widely used in the construction industry as a key raw material for the production of cement and concrete. In the chemical industry, it is used to manufacture lime, calcium carbide, etc. It also plays an important role in agriculture by adjusting soil pH, and in the paper and plastics industries.

[0003] Limestone powder is prone to caking. Existing limestone powder metering and feeding devices often simply convey the limestone powder directly or use a simplistic dispersing method that relies solely on limited stirring action. This fails to adequately disperse the material from all directions and angles, resulting in frequent caking of the limestone powder during the early stages of conveying and processing. This severely hinders the smooth progress of subsequent processing steps, greatly reduces processing quality, and makes it difficult to meet the high-quality requirements of actual production.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 - Figure 5 An embodiment of this utility model is provided: a limestone powder metering and feeding device, including a support frame 1, an auger conveyor 2 installed on the inner side of the support frame 1, a dispersing component provided on the top right side of the auger conveyor 2, a discharge port 21 fixedly connected to the bottom left side of the auger conveyor 2, a metering component provided at the bottom of the discharge port 21, and a feeding component fixedly connected to the bottom inner side of the support frame 1.

[0034] The dispersing assembly includes a dispersing shell 3, which is fixedly connected to the top right side of the auger conveyor 2. A motor 5 is fixedly connected to the outside of the dispersing shell 3. A rotating shaft 6 is fixedly connected to the output end of the motor 5. A square rod 7 is slidably connected inside the rotating shaft 6. A dispersing rod 8 is fixedly connected to the outside of the square rod 7. A swash plate 13 is fixedly connected to the right side of the outside of the dispersing rod 8. A fixing block 11 is fixedly connected to the right side of the inner wall of the dispersing shell 3. Two limit wheels 12 are rotatably connected to the outside of the fixing block 11. A rotating shaft 10 is rotatably connected to the inside of the left side of the dispersing shell 3.

[0035] Specifically, the support frame 1 supports the entire limestone powder metering and feeding device. The auger conveyor 2 includes a motor, conveying cylinder, and auger components, used to convey the limestone powder processed by the dispersing component from one end of the device to the discharge port 21, realizing directional material conveying and ensuring the smooth operation of subsequent metering and feeding. The dispersing shell 3 is used to disperse the limestone powder entering the device, preventing it from agglomerating and ensuring the uniformity of the material, providing good conditions for subsequent processing. The motor 5 provides power to the dispersing component, and the rotating shaft 6 transmits the power of the motor 5, driving the square rod 7 and the dispersing rod 8 to rotate, realizing the initial dispersal of the limestone powder. The square rod 7 is slidably connected to the rotating shaft 6, and can rotate with the rotating shaft 6 when the rotating shaft 6 rotates. Under the action of the inclined plate 13 and the limiting wheel 12, it slides back and forth within the rotating shaft 6, thereby driving the dispersing rod 8 to move left and right, enhancing the dispersing effect. The dispersing rod 8 is used for straight... The limestone powder is then dispersed. During rotation and left-right movement, the clumps of limestone powder are broken down into loose powder. The inclined plate 13 cooperates with the limiting wheel 12 to make the square rod 7 slide back and forth within the rotating shaft 6, changing the movement trajectory of the dispersing rod 8 and improving the dispersing effect. The fixing block 11 is used to fix the limiting wheel 12 and provide support for the limiting wheel 12, ensuring that the limiting wheel 12 can properly perform its limiting function on the inclined plate 13. The limiting wheel 12 is used to restrict the movement trajectory of the inclined plate 13, so that the inclined plate 13 can move along a predetermined path during rotation, thereby driving the square rod 7 to slide back and forth within the rotating shaft 6. The rotating shaft 10 is used to help maintain the stability of the internal structure of the dispersing component and ensure the normal operation of the dispersing work. The discharge port 21 is used to discharge the limestone powder conveyed by the auger conveyor 2 and let it enter the metering component below, which is the channel for the material to enter the metering component from the conveying link.

[0036] Reference Figure 4 The metering component includes two connecting rods 17. The outer side of the connecting rods 17 is fixedly connected to the inner wall of the left side of the support frame 1. The end of the connecting rod 17 away from the connecting rod 17 is fixedly connected to a fixing block 16. A metering hopper 14 is fixedly connected between the two fixing blocks 16. Two cylinders 15 are fixedly connected to the outer side of the metering hopper 14. A U-shaped block 18 is fixedly connected to the output end of the cylinder 15. Two connecting rods 19 are rotatably connected to the bottom of the U-shaped block 18. A cover plate 20 is rotatably connected to the bottom of the connecting rods 19. Multiple metering sensors 9 are installed inside the metering hopper 14.

[0037] Specifically, connecting rod 17 is used to fix the metering assembly to the inner left wall of support frame 1, providing support for components such as metering hopper 14 and ensuring the overall stability of the metering assembly. Fixing block 16 is used to connect connecting rod 17 and metering hopper 14, providing a stable connection so that metering hopper 14 can be firmly installed in the predetermined position. Metering hopper 14 is used to receive limestone powder falling from outlet 21, providing a place for metering limestone powder. Cylinder 15 is used to provide power. When metering sensor 9 detects that the limestone powder in metering hopper 14 has reached the set weight, cylinder 15 is activated, pushing U-shaped block 18 to move. U-shaped block 18 is used to transmit the power of cylinder 1. The power of cylinder 15 is converted into the oscillation of connecting rod 19 through a rotatable connection with connecting rod 19. Connecting rod 19 is used to connect U-shaped block 18 and cover plate 20. Driven by U-shaped block 18, cover plate 20 is rotated, thereby controlling the discharge of metering hopper 14. Cover plate 20 is used to control the opening and closing of the bottom opening of metering hopper 14. When the limestone powder reaches the set weight, cover plate 20 is closed; after reaching the set weight, it is opened under the drive of connecting rod 19 to discharge limestone powder. Metering sensor 9 is used to measure the weight of limestone powder in metering hopper 14 in real time and feed the weight signal back to the control system to achieve accurate metering of limestone powder.

[0038] Reference Figure 5 The feeding assembly includes a hollow shell 22. The outer side of the hollow shell 22 is installed on the lower side of the support frame 1. A feeding plate 23 is fixedly connected to the top of the hollow shell 22. A second motor 24 is fixedly connected to the left wall inside the hollow shell 22. A rotating rod 25 is fixedly connected to the output end of the second motor 24. Multiple cams 26 are fixedly connected to the outer side of the rotating rod 25. Multiple fixing rods 27 are fixedly connected to the inner wall of the hollow shell 22. A striking rod 29 is slidably connected inside two fixing rods 27. A spring 28 is sleeved on the outer side of the fixing rod 27.

[0039] Specifically, the hollow shell 22 is used to install other components of the feeding assembly; the material plate 23 is used to receive limestone powder falling from the metering assembly and serves as a transition platform for conveying limestone powder to subsequent processes, guiding the limestone powder to be fed smoothly; the second motor 24 is used to provide power to the feeding assembly, and its output end drives the rotating rod 25 to rotate, thereby driving the cam 26 to move. The rotating rod 25 is used to transmit the power of the second motor 24, driving multiple cams 26 fixedly connected on the outside to rotate together. The cams 26 are used to abut against the striking rod 29 during rotation, pushing the striking rod 29 against the fixed rod 27. The inner part slides up and down to achieve the striking action of the feed plate 23. The fixed rod 27 is used to provide sliding guide for the striking rod 29, ensuring that the striking rod 29 can slide up and down along a fixed path. At the same time, it provides installation support for the spring 28. The spring 28 is used to provide elastic force to reset the striking rod 29, ensuring that the striking rod 29 can continuously strike the feed plate 23. The striking rod 29 is used to perform up and down reciprocating motion and strike the feed plate 23 under the action of the cam 26 and the spring 28, preventing limestone powder from accumulating on the feed plate 23 and promoting the smooth falling of limestone powder to complete the feeding.

[0040] Reference Figure 1 - Figure 5 The cover plate 20 is rotatably connected to the bottom of the metering hopper 14. One end of the spring 28 is fixedly connected to the outside of the striking rod 29, and the other end of the spring 28 is fixedly connected to the bottom of the feeding plate 23. The cam 26 abuts against the striking rod 29. The end of the rotating rod 25 away from the motor 24 is rotatably connected to the inner wall of the hollow shell 22. The top of the dispersing shell 3 is fixedly connected to the feed port 4. The outside of the inclined plate 13 is set between the two limit wheels 12. The left end of the rotating shaft 10 is rotatably connected to the inside of the dispersing shell 3.

[0041] Specifically, the cover plate 20 is used to control the opening and closing of the bottom opening of the metering hopper 14 to determine whether limestone powder is discharged from the metering hopper 14. The spring 28 provides elastic force to reset the striking rod 29, which is pushed upward by the cam 26. The cam 26 is used to abut against the striking rod 29. When the rotating rod 25 is driven to rotate, it pushes the striking rod 29 to move up and down in the fixed rod 27. The rotating rod 25 is used to rotate under the drive of the motor 24, which drives the outer cam 26 to rotate. The feed port 4 is used as a channel for limestone powder to enter the dispersing shell 3 and guides the material into the device for subsequent processing. The inclined plate 13 is set on the outside between the two limit wheels 12. When the rotating shaft 6 drives the dispersing rod 8 to rotate, it cooperates with the limit wheels 12 to make the square rod 7 slide back and forth in the rotating shaft 6. The rotating shaft 10 is used to help maintain the structural stability inside the dispersing shell 3 and ensure the normal operation of the dispersing component.

[0042] Working principle: When in use, limestone powder enters the dispersing shell 3 through the feed inlet 4. The motor 5 starts and drives the rotating shaft 6 to rotate. The square rod 7 will rotate with the rotating shaft 6, which in turn causes the dispersing rod 8 to rotate to initially disperse the limestone powder. As the rotating shaft 6 rotates, the inclined plate 13, under the limiting action of the limiting wheel 12, causes the square rod 7 to slide back and forth inside the rotating shaft 6, thereby driving the dispersing rod 8 to move left and right, further enhancing the dispersing effect.

[0043] The broken limestone powder falls into the auger conveyor 2, which transports it to the discharge port 21. The limestone powder exiting from the discharge port 21 falls into the metering hopper 14. Multiple metering sensors 9 in the metering hopper 14 measure the weight of the limestone powder in real time. When the set weight is reached, the cylinder 15 is activated, pushing the U-shaped block 18. The U-shaped block drives the connecting rod 19, causing the cover plate 20 to open and the limestone powder to fall out.

[0044] Once inside the feeding assembly, motor 24 starts, driving the rotating rod 25 to rotate. The cam 26 on the rotating rod 25 rotates accordingly. When the cam 26 rotates, it contacts the striking rod 29, causing the striking rod 29 to move up and down within the fixed rod 27. At the same time, it compresses the spring 28 back and forth, striking the feeding plate 23, causing the limestone powder on the feeding plate to fall smoothly, thus completing the feeding process.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
