[0002] In the alloy production process, various raw materials need to be added to the melting furnace in a certain proportion for smelting. Traditional alloy melting furnace equipment usually adopts a simple and fixed mechanical feeding device, that is, each alloy melting furnace equipment needs to be equipped with a dedicated feeding device. This method lacks flexibility and stability, and it is difficult to transfer the feeding device between different alloy melting furnace equipment. Once the existing feeding device is fixedly installed on the alloy melting furnace equipment, it is difficult to guarantee the accuracy and consistency of each feeding, which leads to some materials being easily spilled during the transportation process. This not only causes waste but may also affect the cleanliness of the production environment. In addition, the existing feeding device is not stable enough when turning over and pouring materials, and it is prone to jamming, which may even damage the equipment. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] Reference Figures 1 to 5This application provides an alloy melting furnace feeding device, including a melting furnace body 10 and a raw material feeding device 20 limited and installed at the feeding port of the melting furnace body 10. The raw material feeding device 20 includes a base frame 1, on which two electric cylinders 2 are fixedly installed. The piston rods of the electric cylinders 2 are connected to the base frame 1 by telescopic guides 3. The telescopic guides 3 include a straight guide rail 31 and an L-shaped guide rail 32 that are slidably connected. A connecting frame 4 is slidably installed between the telescopic guides 3. A material box 6 is fixedly installed on the connecting frame 4. A lifting feeding mechanism 5 is installed on the base frame 1 for driving the connecting frame 4 and the material box 6 to lift together and rotate at the top of the L-shaped guide rail 32.

[0024] By adopting the above technical solution, the melting furnace body 10 is the main container for alloy melting, while the raw material feeding device 20 is responsible for accurately conveying the required raw materials into the melting furnace. The raw material feeding device 20 can be transferred between different melting furnace bodies 10 to improve adaptability. The bottom frame 1 of the raw material feeding device 20 serves as the basic support structure of the entire device. Two electric cylinders 2 are symmetrically distributed on the bottom frame 1. The piston rod of the electric cylinder 2 is connected to the bottom frame 1 through a telescopic guide frame 3. The telescopic guide frame 3 consists of a straight guide rail 31 and an L-shaped guide rail 32, allowing the connecting frame 4 to move freely within a certain range. The material box 6 is fixed on the connecting frame 4 to hold the raw materials to be melted. The lifting and feeding mechanism 5 can drive the connecting frame 4 and the material box 6 to rise along the telescopic guide frame 3 and flip at the top corner of the L-shaped guide rail 32, so that the material falls smoothly into the melting furnace. This not only improves the accuracy and efficiency of feeding but also reduces the difficulty of manual operation.

[0025] Reference Figure 2 and Figure 3 Each of the straight guide rails 31 has a Z-shaped limiting bracket 33 fixed on its side. The Z-shaped limiting bracket 33 has two mounting holes at one end near the shell of the melting furnace body 10. The Z-shaped limiting bracket 33 is fixedly connected to the melting furnace body 10 by bolts.

[0026] By adopting the above technical solution, a Z-shaped limiting bracket 33 is provided on the side of the straight guide rail 31. The Z-shaped limiting bracket 33 has two mounting holes at the end near the melting furnace body 10, which is to facilitate the use of bolts to firmly fix it to the melting furnace body 10.

[0027] Reference Figure 2 and Figure 3 Each of the four corners of the base frame 1 is rotatably mounted with a self-locking universal wheel 11. The bottom end of the electric cylinder 2 is fixedly connected to the base frame 1 with a support block 12. The top end of the piston rod of the electric cylinder 2 is fixedly connected to an L-shaped guide rail 32.

[0028] By adopting the above technical solution, self-locking casters 11 are installed at the four corners of the bottom frame 1, which makes the entire device easy to move between different melting furnaces, facilitates layout adjustment and maintenance, and improves adaptability.

[0029] Reference Figure 2 and Figure 3 The bottom end of the L-shaped guide rail 32 is fixed with a plug-in guide rail 321, which is plugged into and connected to the straight guide rail 31. The upper end of the L-shaped guide rail 32 is fixed with a vertical plate 322, and a support 34 is fixed between the vertical plates 322.

[0030] By adopting the above technical solution, the two L-shaped guide rails 32 are fixedly connected by the upright plate 322 and the support 34, which improves the rigidity and reliability of the overall structure. The bottom end of the L-shaped guide rail 32 is equipped with a plug-in guide rail 321, which can be quickly and tightly plugged into the straight guide rail 31 to form a complete guide system.

[0031] Reference Figure 2 and Figure 3 A concave guide shell 35 is fixedly connected between the vertical plates 322. The concave guide shell 35 is installed at an angle, and its bottom end is located at the feeding port of the melting furnace body 10.

[0032] By adopting the above technical solution, the material box 6 rises to the top and naturally flips over to pour the material onto the concave guide shell 35, and the concave guide shell 35 guides the material to slide down to the feeding port of the melting furnace body 10, thereby improving the accuracy of material feeding.

[0033] Reference Figure 4 and Figure 5 The lifting and unloading mechanism 5 includes a motor 51, which is fixed to a base 52. The base 52 is fixed to the bottom frame 1. The output shaft of the motor 51 is connected to the sprockets at the bottom of two chain assemblies 53. The sprockets at the top of the chain assemblies 53 are rotatably mounted on a support 34 via a shaft. The corner arc of the L-shaped guide rail 32 is set. The sprockets at the top of the chain assembly 53 and the corner arc of the L-shaped guide rail 32 are set at the same center. The chain of the chain assembly 53 is also meshed with a tension sprocket 54. The tension sprocket 54 is fixed to a rotating shaft 541. Both ends of the rotating shaft 541 are rotatably connected to sliders 56. Each L-shaped guide rail 32 has a horizontal rail 55 fixed on it. A slider 56 is slidably installed in each horizontal rail 55. A spring 57 is fixedly connected between the horizontal rail 55 and the slider 56.

[0034] By adopting the above technical solution, the output shaft of the motor 51 is connected to the sprockets at the bottom of the two chain assemblies 53, and the other sprocket at the top of the chain assembly 53 is mounted on the support 34 through a shaft, forming a complete loop. It is particularly worth mentioning that the L-shaped guide rail 32 adopts an arc design at its corner, and the sprocket at the top of the chain assembly 53 has the same center as this arc. This layout allows the material box 6 to smoothly transition to a horizontal position during the upward process, and then naturally flip over and dump the material at the top. In order to ensure that the tension of the chain remains moderate during the extension of the telescopic guide 3, a tensioning sprocket 54 and a matching rotating shaft 541 and slider 56 are also provided. The slider 56 can slide freely in the corresponding horizontal rail 55 and maintain appropriate tension through the spring 57.

[0035] Reference Figure 2 and Figure 5 The connecting frame 4 includes a slide plate 41, with two rollers 42 rotatably mounted at both ends of the slide plate 41. The rollers 42 are rolled along the telescopic guide frame 3. Two U-shaped seats 43 are fixed to the back of the slide plate 41. Each U-shaped seat 43 is fixedly connected to a chain of a chain assembly 53 with a connecting rod 44. Two concave seats 45 are fixed to the front of the slide plate 41, and a material box 6 is fixedly installed between the concave seats 45.

[0036] By adopting the above technical solution, two rollers 42 are installed at each end of the slide plate 41. The rollers 42 roll along the guide groove of the telescopic guide 3, so that the entire connecting frame 4 can slide smoothly along the telescopic guide 3. Two U-shaped seats 43 are welded to the back of the slide plate 41. Each U-shaped seat 43 is connected to the corresponding chain assembly 53 through a connecting rod 44. When the chain is running, it can drive the connecting frame 4 to move up and down. At the front of the slide plate 41, a pair of concave seats 45 are used to fix the material box 6. As the rollers 42 roll along the arc corner of the L-shaped guide rail 32, the connecting frame 4 drives the material box 6 to achieve a flipping motion.

[0037] Working principle: The raw material feeding device 20 can be moved and relocated as a whole by four self-locking casters 11 installed on the bottom frame 1. It can be moved to different melting furnace bodies 10 for assembly and use. Only two Z-shaped limit frames 33 need to be fixed to the melting furnace body 10 with bolts. When raw materials need to be added into the alloy melting furnace, the piston rod of the electric cylinder 2 pushes the telescopic guide frame 3 to extend or retract according to the height of the feeding port of the melting furnace body 10. The tension sprocket 54 in the chain assembly 53 extends with the telescopic guide frame 3, and drives the slider 56 to slide along the corresponding horizontal rail 55 through the rotating shaft 541, causing the spring 57 to deform, thereby adjusting the height of the corner of the L-shaped guide rail 32, and together adjusting the height position of the concave guide shell 35. The material box 6 is freely adjusted to its highest flip position to align with the concave guide shell 35 and the feeding port of the melting furnace body 10. The motor 51 operates, driving the connecting frame 4 and the material box 6 to rise along the straight guide rail 31 and the L-shaped guide rail 32 via the chains of the two chain assemblies 53. When the material box 6 reaches the top of the L-shaped guide rail 32, the sprocket at the upper end of the chain assembly 53 is aligned with the corner arc of the L-shaped guide rail 32. Under the action of the U-shaped seat 43, the rollers 42 at both ends of the slide plate 41 smoothly roll and move along the corner of the L-shaped guide rail 32, thus achieving the natural flipping of the material box 6. The material slides through the concave guide shell 35 into the feeding port of the melting furnace body 10. After the material is poured out, the motor 51 reverses its rotation, causing the material box 6 to return to its initial position.

[0038] 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.
