[0002] Iron ore refers to ore containing iron elements, which is widely used in the manufacture of steel and other metal products. As an important industrial raw material, iron ore has an important impact on the global economic and social development. Its mining and utilization methods are constantly evolving to meet the requirements of market demand and environmental protection. This kind of ore usually uses a transfer device to transfer iron ore from the excavation site or storage area to the processing facility.

[0003] In traditional iron ore transfer devices, the starting point is usually a hopper or a silo for receiving and storing iron ore mined from the excavation site or storage area. The hopper is designed to be able to hold a large amount of ore and ensure the uniform outflow of materials. The most common iron ore transfer device is a conveyor belt system. These conveyor belts can be several kilometers long and are used to transport iron ore from the hopper or silo to the downstream processing facility or loading area. The conveyor belt usually includes components such as a drive system, idlers, a support frame, and a belt.

[0004] However, the traditional iron ore transfer device does not have an emergency braking system. When an accident such as a conveyor belt failure or overload occurs, the hopper cannot stop emergently, which may cause accidents to personnel and the site, reducing the safety of this device. Summary of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a transfer device for iron ore, aiming to improve the problem that the traditional iron ore transfer device does not have an emergency braking system. When an accident such as a conveyor belt failure or overload occurs, the hopper cannot stop emergently, which may cause accidents to personnel and the site and reduce the safety of this device.

[0006] To achieve the above object, the utility model adopts the following technical scheme: A transfer device for iron ore includes a hopper. A plurality of fixed platforms are fixedly connected to the side wall of the hopper. A rack is slidably connected inside each fixed platform. A motor is fixedly connected to the bottom of the fixed platform. A worm is fixedly connected to the output end of the motor. A worm gear is rotatably connected to the side wall of the hopper. The worm gear is meshed with the worm. A gear is fixedly connected to the side wall of the worm gear. The gear is meshed with the rack. A sliding shaft is fixedly connected to the bottom of the rack. A rotating column is rotatably connected to the side wall of the hopper. A chute is opened inside the rotating column. The outer wall of the sliding shaft is slidably connected inside the chute. A clamping platform is fixedly connected to the bottom of the rotating column. An opening and closing assembly is arranged on the side wall of the hopper, and the opening and closing assembly is used to open and close the hopper.

[0007] Further, the opening and closing assembly includes a fixing plate, and a plurality of the fixing plates are fixedly connected to the side wall of the hopper.

[0008] Further, a top plate is fixedly connected to the top of the fixing plate, and a shutter is slidably connected inside the hopper.

[0009] Further, an electric push rod is fixedly connected to the lower surface of the top plate, and a push table is fixedly connected to the output end of the electric push rod.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Referring to Figures 1 - 2 As shown in the figure, an embodiment provided by the present invention: A transfer device for iron ore includes a hopper 1. A plurality of fixed platforms 2 are fixedly connected to the side wall of the hopper 1. A rack 3 is slidably connected inside each fixed platform 2. A motor 4 is fixedly connected to the bottom of the fixed platform 2. A worm 5 is fixedly connected to the output end of the motor 4. A worm gear 6 is rotatably connected to the side wall of the hopper 1. The worm gear 6 meshes with the worm 5. A gear 7 is fixedly connected to the side wall of the worm gear 6. The gear 7 meshes with the rack 3. A sliding shaft 9 is fixedly connected to the bottom of the rack 3. A rotating column 8 is rotatably connected to the side wall of the hopper 1. A chute 10 is opened inside the rotating column 8. The outer wall of the sliding shaft 9 is slidably connected inside the chute 10. A clamping platform 11 is fixedly connected to the bottom of the rotating column 8. An opening and closing assembly is arranged on the side wall of the hopper 1, and the opening and closing assembly is used to open and close the hopper 1.

[0024] Specifically, the motor 4 drives the worm 5 to start rotating by outputting a rotational force. The meshing relationship between the worm 5 and the worm gear 6 causes the worm gear 6 to start rotating on the side wall of the hopper 1. As the worm gear 6 rotates, the gear 7 on its side wall also starts rotating synchronously. The gear 7 meshes with the rack 3 inside the fixed platform 2, causing the rack 3 to start sliding vertically inside the fixed platform 2. During the sliding process of the rack 3, it drives the sliding shaft 9 at its bottom to slide along a preset trajectory inside the chute 10. The design of the chute 10 ensures the movement trajectory of the sliding shaft 9, thereby causing the rotating column 8 to rotate. The rotation of the rotating column 8 is transmitted to the clamping platform 11 at its bottom, causing the clamping platform 11 to rotate and clamp the conveyor belt, quickly stopping the movement of the hopper 1. This structural design effectively protects the operator from harm and ensures the safety of the equipment and personnel in case of emergency.

[0025] Referring to Figure 3, the opening and closing assembly includes a fixed plate 12. A plurality of fixed plates 12 are fixedly connected to the side wall of the hopper 1. The top of the fixed plate 12 is fixedly connected to a top plate 13. A shutter 19 is slidably connected inside the hopper 1. The lower surface of the top plate 13 is fixedly connected to an electric push rod 14. The output end of the electric push rod 14 is fixedly connected to a push table 15. The bottom of the push table 15 is fixedly connected to a connecting column 16. Both ends of the connecting column 16 are fixedly connected to connecting plates 17. The connecting plates 17 are symmetric with each other. A plurality of pulleys 18 are rotatably connected to the side walls of the connecting plates 17. The pulleys 18 are slidably connected inside the fixed plate 12. A plurality of pull rods 21 are rotatably connected to the side walls of the pulleys 18. A plurality of connecting platforms 20 are fixedly connected to the side wall of the shutter 19. The inside of the connecting platform 20 is rotatably connected to one end of the shutter 19.

[0026] Specifically, the electric push rod 14 drives the push table 15 to move vertically by outputting a rotational force. The push table 15 then pushes the bottom part of the connecting column 16. The connecting plates 17 on the side wall of the connecting column 16 slide inside the fixed plate 12 through a plurality of pulleys 18, thereby guiding the vertical displacement of the connecting column 16. As the connecting column 16 moves, a plurality of pull rods 21 on the side wall of the connecting column 16 start to rotate and change their inclination angles. The moving force of these pull rods 21 is transmitted through the connecting platform 20. After the connecting platform 20 is subjected to force, it drives the shutter 19 on its side wall to open from inside the hopper 1, enabling the operator to easily perform the operations of discharging and taking iron ore, ensuring the operation efficiency and safety of the iron ore transportation system.

[0027] Working principle: When it is necessary to emergently brake this device, start the motor 4. The motor 4 outputs a rotational force to the worm 5 to drive the worm 5 to rotate. At this time, through the meshing relationship between the worm 5 and the worm gear 6, the worm gear 6 is driven to rotate on the side wall of the hopper 1. The rotation of the worm gear 6 drives the gear 7 on its side wall to rotate synchronously. The gear 7 drives the rack 3 to slide vertically inside the fixed table 2 through the meshing relationship with the rack 3. During the sliding process of the rack 3, the sliding shaft 9 at its bottom is driven to slide inside the chute 10. Through the trajectory design of the chute 10, the rotating column 8 rotates, and then drives the clamping table 11 at its bottom to rotate and clamp in the conveyor belt to emergently stop the movement of the hopper 1. This structure protects personnel from harm, avoids equipment damage, and improves the safety and reliability of the transportation process. When it is necessary to open this hopper 1 for discharging or taking materials, start the electric push rod 14. The electric push rod 14 outputs a rotational force to the push table 15 to drive the push table 15 to move vertically. The push table 15 pushes the connecting column 16 at its bottom, causing the connecting plates 17 on the side wall of the connecting column 16 to drive the connecting column 16 to vertically displace through the sliding of a plurality of pulleys 18 on its side wall inside the fixed plate 12. During the movement of the connecting column 16, a plurality of pull rods 21 on its side wall rotate and change their inclination angles, thereby pulling the connecting platform 20. After the connecting platform 20 is subjected to force, it drives the shutter 19 on its side wall to open from inside the hopper 1. This structure facilitates the taking and placing of iron ore and improves its transfer efficiency.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
