When the layout of the steelmaking furnace changes, such fixed structure devices are difficult to meet the needs, and often need to be reinstalled or replaced. This results in long equipment modification time and high costs, which greatly affects the production schedule. In addition, some conveying devices with mobile functions are difficult to ensure precise docking with the fixed conveying part during the movement, which can easily lead to problems such as conveyor belt deviation and material spillage. This not only causes material waste but also poses safety hazards.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0029] like Figure 1-5 As shown, this utility model discloses a material conveying device for a steelmaking furnace charge trough, including a fixed conveyor seat 1, a movable conveyor seat 2, and a conveyor belt 3. The movable conveyor seat 2 is movably installed on one side of the fixed conveyor seat 1, and the movable conveyor seat 2 and the fixed conveyor seat 1 are aligned with each other to ensure that the conveyor belt 3 can run smoothly.
[0030] The fixed conveyor seat 1 has brackets 9 fixedly installed on both sides of its outer wall. A lead screw 12 is rotatably installed inside the bracket 9. A servo motor 10 is fixedly installed on the outer wall of the bracket 9, and the shaft of the servo motor 10 is connected to the lead screw 12 for transmission. The movable conveyor seat 2 has sliders 11 symmetrically arranged on both sides of its outer wall. A screw hole 16 is drilled through the inside of each slider 11, and the lead screw 12 passes through the screw hole 16. When the servo motor 10 drives the lead screw 12 to rotate, due to the engagement between the lead screw 12 and the screw hole 16, the slider 11 will drive the movable conveyor seat 2 to move axially along the lead screw 12, thereby achieving position adjustment of the movable conveyor seat 2.
[0031] A first roller 13 is installed on one side of the interior of the fixed conveyor seat 1, and a second roller 14 is installed on one side of the interior of the movable conveyor seat 2. A conveyor belt 3 is installed on both the first and second rollers 13. A drive motor 4 is installed on the side wall of the fixed conveyor seat 1, near the first roller 13, and its shaft is connected to the first roller 13. The drive motor 4 drives the first roller 13 to rotate, which in turn drives the second roller 14 to rotate via the conveyor belt 3, thus achieving material conveying.
[0032] The other side of the movable conveyor seat 2 is provided with a discharge port 8, which is inclined at an angle of 30°-60°, preferably 45°. This inclined arrangement facilitates the smooth discharge of materials from the discharge port 8 and avoids material accumulation.
[0033] The fixed conveyor seat 1 has a first support leg 5 at its bottom, and the movable conveyor seat 2 has a second support leg 6 at its bottom. The second support leg 6 has casters 7 on both sides of its bottom, and these casters are lockable swivel casters. The lockable swivel casters allow the movable conveyor seat 2 to move more flexibly, and can be locked after reaching a designated position, ensuring the stability of the device.
[0034] The fixed conveyor seat 1 has a U-shaped slot 17 inside. The movable conveyor seat 2 has a U-shaped connecting plate 15 integrally formed at one end near the fixed conveyor seat 1. The U-shaped connecting plate 15 is inserted into the U-shaped slot 17. The cooperation between the U-shaped slot 17 and the U-shaped connecting plate 15 ensures the alignment accuracy between the movable conveyor seat 2 and the fixed conveyor seat 1, and also plays a guiding role during the movement of the movable conveyor seat 2.
[0035] The lead screw 12 has a pitch of 5mm-15mm, preferably 10mm, and its length is greater than the maximum travel distance of the movable conveyor 2 to ensure sufficient travel. The control circuit of the servo motor 10 includes travel limit switches to prevent the movable conveyor 2 from moving beyond a preset range, and these limit switches are located at both ends of the lead screw 12. These travel limit switches effectively prevent excessive movement of the movable conveyor 2, ensuring safe operation of the device.
[0036] In actual use, firstly, based on the position of the steelmaking furnace feed trough, start the servo motor 10. Adjust the position of the movable conveyor seat 2 using the lead screw 12 and screw hole 16, aligning the discharge port 8 with the feed trough. After adjustment, lock the moving wheel 7 to ensure device stability. Then, install the conveyor belt 3 onto the two sets of rollers, and start the drive motor 4 to drive the first roller 13 to rotate. This, in turn, drives the second roller 14 to rotate via the conveyor belt 3, transporting the material from the fixed conveyor seat 1 to the movable conveyor seat 2, and discharging it into the feed trough through the discharge port 8.
[0037] This utility model discloses a steelmaking furnace charge conveying device. A servo motor 10 drives a lead screw 12 to rotate, adjusting the position of the movable conveyor seat 2. This allows the discharge port 8 to accurately align with the charge trough at different positions, improving the device's applicability. The cooperation between the U-shaped slot 17 and the U-shaped connecting plate 15 ensures the alignment accuracy and movement stability of the movable conveyor seat 2 and the fixed conveyor seat 1. Lockable casters make the movement of the movable conveyor seat 2 more flexible and convenient. The coordinated operation of all components improves the efficiency and accuracy of material conveying in the steelmaking furnace charge trough.
[0038] As a preferred example of this application, the lead screw 12 is a trapezoidal lead screw, which has the advantages of high transmission efficiency, strong load-bearing capacity and good self-locking performance, and can meet the position adjustment requirements of the movable conveyor seat 2.
[0039] As a preferred example of this application, the conveyor belt 3 is a high-temperature resistant conveyor belt. Since the material transported in the steelmaking furnace charge trough is at a high temperature, the high-temperature resistant conveyor belt can ensure normal operation in a high-temperature environment and extend the service life of the conveyor belt 3.
[0040] As a preferred example of this application, the height of the first leg 5 and the second leg 6 is adjustable. By adjusting the height of the first leg 5 and the second leg 6, the device can be adapted to different working sites and material trough heights, thereby improving the versatility of the device.
[0041] As a preferred example of this application, the inner walls of both the fixed conveyor seat 1 and the movable conveyor seat 2 are provided with wear-resistant liners. The wear-resistant liners can reduce the wear of materials on the inner walls of the conveyor seats and extend the service life of the device.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
