Description

Technical Field

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

[0002] Cement is a powdery hydraulic inorganic binder. When mixed with water, the resulting paste can harden in air or water and can firmly bind materials such as sand and stone together. It is widely used in civil engineering, water conservancy, national defense and other engineering projects.

[0003] In the cement production process, cement is transported to processing equipment via a conveying device. For example, a prior art conveying device for cement processing (CN221821286U) can transport cement to a suitable height as needed, significantly reducing workload. Simultaneously, through the arrangement of a baffle rod and a fixed shaft, the baffle rod loosens the cement inside the storage trough, facilitating the thorough emptying of the cement and preventing waste due to incomplete conveying. However, the existing technology only uses a baffle rod to feed cement into the storage trough, resulting in poor loosening. Some cement adheres to the inner wall of the storage trough and the baffle rod, leading to incomplete emptying. Therefore, those skilled in the art have proposed a cement conveying device for cement production to address the problems mentioned above. Utility Model Content

[0004] The purpose of this utility model is to provide a cement conveying device for cement production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cement conveying device for cement production includes a support frame, a guide rod installed inside the support frame, a lifting frame slidably mounted on the guide rod, support arms mounted at both ends of the lifting frame, a fixed shaft mounted at the end of each support arm away from the lifting frame, a storage hopper rotatably mounted on the fixed shaft, the inner wall of the storage hopper being arc-shaped, one end of a hydraulic rod hinged to the lifting frame, and the other end of the hydraulic rod hinged to the storage hopper, and further includes:

[0007] Extension blocks are installed at both ends of the storage hopper, and a rotating shaft is rotatably installed inside the storage hopper, with a stirring rod installed on the rotating shaft;

[0008] A swing mechanism, which is disposed within the extension block, is used to drive the rotating shaft to swing axially;

[0009] A transmission mechanism, which is mounted on a fixed shaft, is used to drive the swing mechanism;

[0010] A lifting mechanism is installed inside the support frame and is used to drive the lifting frame to move up and down.

[0011] As a further embodiment of this utility model: a scraper that fits against the inner wall of the storage hopper is installed at the end of the stirring rod away from the rotating shaft.

[0012] As a further embodiment of this utility model: the swing mechanism includes a first inner cavity and a second inner cavity respectively opened in two extension blocks. A sliding plate is slidably arranged in the first inner cavity. The sliding plate is connected to the inner wall of the first inner cavity by a spring. The sliding plate is connected to one end of a rotating shaft. A rotating block is rotatably arranged in the second inner cavity. A rectangular block that is slidably connected to the rotating block is installed at one end of the rotating shaft that passes through the second inner cavity. A limiting plate is installed on the rotating shaft, and a second magnet is installed on the limiting plate. Several first magnets distributed in a ring are installed on the inner wall of the second inner cavity.

[0013] As a further embodiment of this utility model: the transmission mechanism includes a second gear mounted on a fixed shaft, and a first gear meshing with the second gear is mounted on the rotating block.

[0014] As a further embodiment of this utility model: the lifting mechanism includes a threaded rod rotatably disposed in the support frame, the threaded rod being threadedly connected to the lifting frame, and a motor connected to the threaded rod being installed on the top of the support frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model can drive the lifting frame to rise and fall along the guide rod through the lifting mechanism, thereby adjusting the tilting height of the storage hopper. The position of the storage hopper can be adjusted according to the height of the feeding port of the processing equipment. When tilting, the hydraulic rod pushes the storage hopper to rotate around the fixed axis, and the rotating shaft will rotate and swing axially under the drive of the transmission mechanism. Thus, while feeding the cement in the storage hopper, the cement adhering to the storage hopper or the stirring rod can also be shaken off, thereby completely tilting the cement in the storage hopper and avoiding incomplete tilting.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] Please see Figures 1-4 A cement conveying device for cement production includes a support frame 1, a guide rod 2 installed inside the support frame 1, a lifting frame 3 slidably mounted on the guide rod 2, support arms 6 mounted at both ends of the lifting frame 3, a fixed shaft 7 mounted at the end of the support arm 6 away from the lifting frame 3, a storage hopper 8 rotatably mounted on the fixed shaft 7, the inner wall of the storage hopper 8 being arc-shaped, one end of a hydraulic rod 24 hinged to the lifting frame 3, and the other end of the hydraulic rod 24 hinged to the storage hopper 8, and further includes:

[0023] Extension blocks 9 are installed at both ends of the storage hopper 8. A rotating shaft 10 is rotatably installed inside the storage hopper 8, and an agitator 11 is installed on the rotating shaft 10.

[0024] A swing mechanism is provided inside the extension block 9 to drive the rotating shaft 10 to swing axially.

[0025] A transmission mechanism is mounted on a fixed shaft 7 and is used to drive the swing mechanism;

[0026] A lifting mechanism is installed inside the support frame 1 and is used to drive the lifting frame 3 to move up and down.

[0027] The lifting mechanism can drive the lifting frame 3 to rise and fall along the guide rod 2, thereby adjusting the tilting height of the storage hopper 8. The position of the storage hopper 8 can be adjusted according to the height of the feeding port of the processing equipment. When tilting, the hydraulic rod 24 pushes the storage hopper 8 to rotate around the fixed shaft 7, and the rotating shaft 10 will rotate and swing axially under the drive of the transmission mechanism. This allows the cement in the storage hopper 8 to be fed while the cement adhering to the storage hopper 8 or the stirring rod 11 is shaken off, so that the cement in the storage hopper 8 can be completely tilted and incomplete tilting can be avoided.

[0028] In one embodiment, the end of the stirring rod 11 away from the rotating shaft 10 is equipped with a scraper 12 that fits against the inner wall of the storage hopper 8.

[0029] Driven by the oscillating mechanism, the rotating shaft 10 will rotate and oscillate axially, thereby driving the stirring rod 11 to rotate and simultaneously driving the scraper 12 to rotate. During the rotation, the scraper 12 will clean the cement adhering to the inner wall of the storage hopper 8, thereby preventing cement from adhering and causing the storage hopper 8 to be unable to be poured out.

[0030] In one embodiment, the swing mechanism includes a first inner cavity 13 and a second inner cavity 16 respectively opened in two extension blocks 9. A slide plate 14 is slidably disposed in the first inner cavity 13. The slide plate 14 is connected to the inner wall of the first inner cavity 13 by a spring 15. The slide plate 14 is connected to one end of a rotating shaft 10. A rotating block 17 is rotatably disposed in the second inner cavity 16. A rectangular block 18 that is slidably connected to the rotating block 17 is installed at one end of the rotating shaft 10 that passes through the second inner cavity 16. A limiting plate 20 is installed on the rotating shaft 10, and a second magnet 21 is installed on the limiting plate 20. A plurality of first magnets 19 distributed in a ring are installed on the inner wall of the second inner cavity 16.

[0031] When the hydraulic rod 24 pushes the storage hopper 8 to rotate around the fixed shaft 7, the transmission mechanism drives the rotating block 17 to rotate. The rectangular block 18, which is slidably connected to the rotating block 17, drives the rotating shaft 10 to rotate, thereby driving the stirring rod 11 to feed the cement in the storage hopper 8 for easy unloading. At the same time, when the rotating shaft 10 rotates, the second magnet 21 on the mounting plate will intermittently approach the first magnet 19. When the first magnet 19 and the second magnet 21 approach each other, the magnetic repulsion between them can push the limiting plate 20 to move within the second inner cavity 16, which in turn can push the rotating shaft 10 to move. This causes the other end of the rotating shaft 10 to press against the sliding plate 14, which in turn compresses the spring 15. When the first magnet 19 separates from the second magnet 21, the spring 15 returns to its original position, pushing the limiting plate 20 on the rotating shaft 10 to return to its original position. Repeating the above operation allows the rotating shaft 10 to rotate while simultaneously swinging axially. During the swinging process, the limiting plate 20 will impact the inner wall of the storage hopper 8, thereby shaking off the cement adhering to the inner wall of the storage hopper 8. Furthermore, as the rotating shaft 10 swings, the cement adhering to the stirring rod 11 and the scraper 12 will also be shaken off, thus achieving complete discharge of cement from the storage hopper 8.

[0032] In one embodiment, the transmission mechanism includes a second gear 23 mounted on a fixed shaft 7, and a first gear 22 that meshes with the second gear 23 is mounted on the rotating block 17.

[0033] During the rotation of the storage hopper 8 around the fixed shaft 7, the second gear 23 is fixed and the first gear 22 rotates around the fixed shaft 7, which will drive the first gear 22 to rotate, and then drive the rotating block 17 to rotate.

[0034] In one embodiment, the lifting mechanism includes a threaded rod 4 rotatably disposed within the support frame 1, the threaded rod 4 being threadedly connected to the lifting frame 3, and a motor 5 connected to the threaded rod 4 being mounted on the top of the support frame 1.

[0035] When it is necessary to adjust the tilting height of the storage hopper 8, the motor 5 is started by the external controller. The motor 5 drives the threaded rod 4 to rotate, thereby driving the lifting frame 3 to lift and lower. This allows for adaptive adjustment according to the height of the feeding port of the processing equipment.

[0036] This utility model uses a lifting mechanism to drive the lifting frame 3 to rise and fall along the guide rod 2, thereby adjusting the tilting height of the storage hopper 8. The position of the storage hopper 8 can be adjusted according to the height of the feeding port of the processing equipment. When tilting, the hydraulic rod 24 pushes the storage hopper 8 to rotate around the fixed shaft 7, and the rotating shaft 10 will rotate and swing axially under the drive of the transmission mechanism. This allows the cement in the storage hopper 8 to be fed while the cement adhering to the storage hopper 8 or the stirring rod 11 is shaken off, thus ensuring that the cement in the storage hopper 8 is completely tilted and avoiding incomplete tilting.
