Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically a feeding device for cement production. Background Technology

[0002] In cement production, the feeding device is a crucial component of the entire production line. Cement production typically involves the mixing and conveying of various raw materials, including limestone, clay, iron ore, and coal. These raw materials require effective conveying and pretreatment by the feeding device before entering subsequent crushing, grinding, and calcination processes.

[0003] According to a search, Chinese patent document, publication number CN215885245U, discloses a feeding device for cement production. By controlling the extension and retraction of the piston rod of the pushing component, the angle between the machine body and the mounting platform is adjusted to facilitate the conveying of materials to different heights of the material receiving platform. However, in actual use, due to the lack of a locking structure for the piston rod, leaks in the air passage can easily cause the conveying device to drop in height. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding device for cement production, which has the advantages of being able to adjust the angle and position of the conveying device to adapt to material platforms of different heights, thus solving the aforementioned technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for cement production, comprising a conveying pipe, a connecting rod one and a connecting rod two fixedly connected to the outer surface of the conveying pipe, a vertical plate rotatably connected to one end of the connecting rod one, a connecting plate rotatably connected to one end of the connecting rod two, an adjusting block rotatably connected to one end of the connecting plate, an adjusting rod threadedly connected to the inside of the adjusting block, and a guide rail slidably connected to the bottom of the adjusting block, a base plate provided at the bottom of the guide rail, an adjusting handwheel fixedly connected to one end of the adjusting rod, a side plate fixedly connected to the top of the base plate, a short round pipe fixedly connected to one end of the outer surface of the conveying pipe, a sleeve fixedly connected to the inside of the short round pipe, and a discharge pipe sleeved onto the outer surface of the sleeve.

[0008] Preferably, one end of the conveying pipe is connected to the drive motor via a flange, and an auger rod is installed inside the conveying pipe, with the output shaft of the drive motor connected to the auger rod.

[0009] With the above technical solution, the drive motor serves as the power source. When the drive motor is started, its output shaft rotates, causing the auger rod to rotate inside the conveying pipe. The spiral blade structure on the auger rod can apply axial thrust to the cement production material entering the conveying pipe, thereby causing the material to move forward along the direction of the conveying pipe and achieving stable material conveying. The conveying pipe and the drive motor are connected by a flange, which has the characteristics of strong connection and good sealing.

[0010] Preferably, a feed hopper is fixedly connected to the outer surface of the conveying pipe, and two vertical plates are fixedly connected to the top surface of the bottom plate.

[0011] The above technical solution reduces the time and labor intensity of manually adding materials one by one by centrally feeding through the hopper, and improves the feeding speed.

[0012] Preferably, both sides of the adjusting block are fixedly connected to a rotating shaft, one end of the rotating shaft is rotatably connected to a connecting plate, and both ends of the adjusting rod are rotatably connected to side plates.

[0013] Through the above technical solution, the adjusting block is rotatably connected to the connecting plate via rotating shafts on both sides. When the adjusting handwheel is rotated, causing the adjusting rod to rotate, the adjusting block slides on the guide rail due to the threaded connection between the adjusting rod and the adjusting block. The connecting plate changes angle as the adjusting block moves, thereby causing the conveying pipe to rotate around the connection point of the connecting rod, thus adjusting the angle position of the conveying pipe to adapt to material platforms of different heights and facilitating the delivery of materials to designated positions. The two ends of the adjusting rod are rotatably connected to the side plates, providing stable support and guidance for the movement of the adjusting block. During the adjustment process, the adjusting rod can rotate around the connection point on the side plate, ensuring that the adjusting block slides smoothly on the guide rail and preventing the adjusting block from shifting or shaking under external force or during movement. This ensures the accuracy and stability of the conveying pipe angle adjustment and is beneficial for the stable delivery of materials.

[0014] Preferably, the lower surface of the adjusting block has two sliding grooves, and guide rails are slidably connected in the two sliding grooves. The guide rails are installed on the upper surface of the base plate by bolts.

[0015] Through the above technical solution, the two sliding grooves on the lower surface of the adjusting block are slidably connected to the guide rail, providing precise guidance for the movement of the adjusting block. When adjusting the angle of the conveying pipe, the adjusting block slides smoothly along the guide rail, ensuring the accuracy of its movement direction and preventing the adjusting block from deviating or shaking during the force process, thereby ensuring the stability of the entire adjusting mechanism.

[0016] Preferably, the discharge pipe includes a collar disposed at the top, the collar being rotatably connected to the bottom end of the short round pipe, and a knob being threadedly connected to the top of the collar.

[0017] Through the above technical solution, the positions of the material platform or subsequent equipment may vary during the cement production process. By loosening the knob and rotating the discharge pipe to adjust its angle, the outlet of the discharge pipe can be precisely aligned with the unloading point at different heights and directions, ensuring that the material can be accurately delivered to the designated location. This improves the adaptability of the feeding device to different production layouts, reduces material spillage and conveying deviation, and ensures the smooth operation of the production process.

[0018] Compared with the prior art, this utility model provides a feeding device for cement production, which has the following beneficial effects:

[0019] This invention features an adjusting block connected to a connecting plate via a rotating shaft, an adjusting rod rotatably connected to a side plate, and a sliding groove and guide rail slidably connected under the adjusting block. Rotating the adjusting handwheel allows the adjusting block to slide, causing the conveying pipe to rotate around the connecting rod, thus adjusting its angle to adapt to different material platforms of varying heights. The discharge pipe's collar is rotatably connected to a short round pipe and has a knob. Loosening the knob allows the discharge pipe to be rotated to align with the unloading point, improving the device's adaptability to different production layouts and reducing material spillage and conveying deviation.

Detailed Implementation

[0025] 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.

[0026] Please see Figures 1-4 A feeding device for cement production includes a conveying pipe 1. A connecting rod 2 and a connecting rod 3 are fixedly connected to the outer surface of the conveying pipe 1. A vertical plate 4 is rotatably connected to one end of the connecting rod 2. A connecting plate 5 is rotatably connected to one end of the connecting rod 3. An adjusting block 6 is rotatably connected to one end of the connecting plate 5. An adjusting rod 7 is threadedly connected to the inside of the adjusting block 6. A guide rail 8 is slidably connected to the bottom of the adjusting block 6. A base plate 9 is provided at the bottom of the guide rail 8. An adjusting handwheel 10 is fixedly connected to one end of the adjusting rod 7. A side plate 11 is fixedly connected to the top of the base plate 9. A short round pipe 12 is fixedly connected to one end of the outer surface of the conveying pipe 1. A sleeve 13 is fixedly connected to the inside of the short round pipe 12. A discharge pipe 14 is sleeved on the outer surface of the sleeve 13.

[0027] Specifically, one end of the conveying pipe 1 is connected to the drive motor 15 via a flange, and an auger rod 16 is installed inside the conveying pipe 1. The output shaft of the drive motor 15 is connected to the auger rod 16. The advantage is that the drive motor 15 serves as a power source. When the drive motor 15 is started, its output shaft rotates, causing the auger rod 16 to rotate inside the conveying pipe 1. The spiral blade structure on the auger rod 16 can apply axial thrust to the cement production material entering the conveying pipe 1, thereby causing the material to move forward along the direction of the conveying pipe 1, achieving stable material conveying. The conveying pipe 1 and the drive motor 15 are connected via a flange, which has the characteristics of strong connection and good sealing.

[0028] Specifically, a feed hopper 17 is fixedly connected to the outer surface of the conveying pipe 1, and two vertical plates 4 are fixedly connected to the top surface of the bottom plate 9. The advantage is that centralized feeding through the feed hopper 17 reduces the time and labor intensity of manually adding materials one by one, and improves the feeding speed.

[0029] Specifically, both sides of the adjusting block 6 are fixedly connected to rotating shafts. One end of the rotating shaft is rotatably connected to the connecting plate 5, and both ends of the adjusting rod 7 are rotatably connected to the side plate 11. The advantage is that the adjusting block 6 is rotatably connected to the connecting plate 5 via the rotating shafts on both sides. When the adjusting handwheel 10 is rotated, causing the adjusting rod 7 to rotate, the adjusting block 6 will slide on the guide rail 8 due to the threaded connection between the adjusting rod 7 and the adjusting block 6. The connecting plate 5 will change angle as the adjusting block 6 moves, thereby causing the conveying pipe 1 to rotate around the connection point of the connecting rod 2, thus adjusting the angle of the conveying pipe 1. This allows it to adapt to material platforms of different heights, facilitating the delivery of materials to designated positions. The two ends of the adjusting rod 7 are rotatably connected to the side plate 11, providing stable support and guidance for the movement of the adjusting block 6. During adjustment, the adjusting rod 7 can rotate around the connection point on the side plate 11, ensuring that the adjusting block 6 slides smoothly on the guide rail 8. This prevents the adjusting block 6 from shifting or shaking under external force or during movement, ensuring the accuracy and stability of the angle adjustment of the conveying pipe 1, which is beneficial for the stable delivery of materials.

[0030] Specifically, the lower surface of the adjusting block 6 has two grooves, and guide rails 8 are slidably connected within these grooves. The guide rails 8 are bolted to the upper surface of the base plate 9. The advantage is that the slidable connection between the two grooves on the lower surface of the adjusting block 6 and the guide rails 8 provides precise guidance for the movement of the adjusting block 6. When adjusting the angle of the conveying pipe 1, the adjusting block 6 slides smoothly along the guide rails 8, ensuring the accuracy of its movement direction and preventing the adjusting block 6 from shifting or shaking during the application of force, thus guaranteeing the stability of the entire adjusting mechanism.

[0031] Specifically, the discharge pipe 14 includes a collar 141 located at the top, which is rotatably connected to the bottom end of the short circular pipe 12. A knob 142 is threadedly connected to the top of the collar 141. The advantage is that during cement production, the positions of the material feeding platform or subsequent equipment may differ. By loosening the knob 142 and rotating the discharge pipe 14 to adjust its angle, the outlet of the discharge pipe 14 can be precisely aligned with unloading points at different heights and directions. This ensures that materials are accurately delivered to the designated location, improves the adaptability of the feeding device to different production layouts, reduces material spillage and conveying deviations, and guarantees the smooth operation of the production process.

[0032] During use, first, check the connections of each component of the device, ensuring that the conveying pipe 1 and the drive motor 15 are securely connected via flanges, and that the auger rod 16 is properly connected to the output shaft of the drive motor 15. Simultaneously, confirm that the feed hopper 17 is securely installed on the conveying pipe 1, that the adjusting block 6 is rotatably connected to the connecting plate 5 via two rotating shafts, that the adjusting rod 7 is rotatably connected to the side plate 11 at both ends, that the slide groove under the adjusting block 6 is slidably connected to the guide rail 8, and that the guide rail 8 is bolted to the base plate 9, that the collar 141 of the discharge pipe 14 is rotatably connected to the bottom end of the short round pipe 12, and that the knob 142 is in its initial state. Next, feed the cement production material into the conveying pipe 1 through the feed hopper 17. Then, start the drive motor 15. The output shaft of the drive motor 15 drives the auger rod 16 to rotate inside the conveying pipe 1. The spiral blade structure of the auger rod 16 applies axial thrust to the material, causing the material to move forward along the conveying pipe 1. Finally, depending on the position of the material platform or subsequent equipment, if the angle of the conveying pipe 1 needs to be adjusted, turn the adjusting handwheel 10 to drive the adjusting rod 7 to rotate, so that the adjusting block 6 slides on the guide rail 8. The connecting plate 5 moves with the adjusting block 6, causing the conveying pipe 1 to rotate around the connection point of the connecting rod 1-2. If the angle of the discharge pipe 14 needs to be adjusted, loosen the knob 142 and rotate the discharge pipe 14. After adjustment, tighten the knob 142 to accurately convey the material to the designated position.
