Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1: Please refer to Figure 1-Figure 5 As shown, the utility model provides a technical solution: a batching metering device for charging an electric arc furnace, comprising a base 1, a bin body 2 is fixedly connected to the base 1, and a discharge port 3 is provided at the bottom end of the bin body 2, and fixed blocks 4 are fixedly connected to both side walls of the bin body 2, and the upper ends of the two fixed blocks 4 are fixedly connected to a storage bin 5, and a discharge port is provided on the side wall of the storage bin 5, and a cabinet door is hinged on the storage bin 5 outside the discharge port, and a drive motor 6 is fixedly connected inside the bin body 2.

[0028] This technical solution utilizes the setting of the storage bin 5 and the drive motor 6.

Then, the cabinet door on the side of the storage bin 5 is opened, and the raw materials to be processed are added to the storage bin 5. After the addition is completed, the cabinet door can be closed.

[0029] Example 2: The technical content disclosed in this embodiment is an improvement based on the above-mentioned Example 1. In the existing process, workers are required to manually put the raw materials into the batching metering device for weighing each time they add materials. Because of the problem of inaccurate raw material addition caused by manual operation, the accuracy of the ingredients and the quality of the product are affected. Although the weighing can be done through the metering sensor, it is not convenient to take out the excess raw materials. Figure 1 and Figure 2 As shown, a weighing assembly of a metering device is disclosed, wherein the output end of a driving motor 6 is fixedly connected to a disc 7, a rotating shaft 8 is fixedly connected to the disc 7, a guide groove 9 is provided on the disc 7, a moving member 10 is provided in the guide groove 9, and a push rod 11 is fixedly connected to the upper end of the moving member 10, a slot 12 is provided in the fixed block 4 below the storage bin 5, and a baffle 13 is slidably connected in the slot 12, a material receiving tube 14 is fixedly connected in the baffle 13, and a rotating plate 15 is rotatably connected to the bottom end of the material receiving tube 14, and the disc 7 is provided with a guide groove 9. The rotation is set in the warehouse body 2, and the guide groove 9 on the disc 7 is an arc-shaped structure. The guide groove 9 is slidably connected to the moving part 10, and there are two guide grooves 9 and moving parts 10 symmetrically arranged about the disc 7, and the push rod 11 on the moving part 10 corresponds to the baffle 13. The end of the push rod 11 away from the moving part 10 extends into the slot 12 and is fixedly connected to the baffle 13, and the material receiving pipe 14 on the baffle 13 corresponds to the bottom opening of the storage bin 5, and the diameter of the material receiving pipe 14 is smaller than the diameter of the rotating plate 15.

[0030] In this technical solution, Figure 1As shown, by using the material receiving tube 14 and the rotating plate 15, when the material receiving tube 14 is aligned with the bottom opening of the storage bin 5, the raw materials in the storage bin 5 will automatically fall into the material receiving tube 14. Since the depth of the material receiving tube 14 is constant, the amount of raw materials falling into the material receiving tube 14 each time is relatively consistent, and there is no need to frequently add or adjust the raw materials manually, which greatly saves time and labor costs.

[0031] It uses Figure 2 The technical solution shown in the figure, first in the initial state, the receiving tube 14 in the baffle 13 is aligned with the bottom opening of the storage bin 5, so that the raw materials in the storage bin 5 will automatically fall into the receiving tube 14 under the action of gravity, and after the raw materials completely fill the receiving tube 14, the driving motor 6 is started at this time, and the driving motor 6 will drive the disc 7 to rotate, so that the moving part 10 slides along the guide groove 9, and then the moving part 10 will simultaneously push the rod 11 to move while moving, so that the pushing rod 11 pushes the baffle 13, the receiving tube 14 and the rotating plate 15 to move at the same time, and the receiving tube 14 will be staggered with the bottom opening of the storage bin 5, and the baffle 13 will further prevent blocking to prevent the raw materials in the storage bin 5 from falling into the slot 12, and then after the rotating plate 15 is separated from the inner wall of the slot 12, the rotating plate 15 is rotated. The plate 15 is affected by gravity and automatically rotates and opens, so that the raw materials in the material receiving tube 14 automatically fall into the discharge port 3. Then, the driving motor 6 is used to control the disc 7 to rotate in the opposite direction, so that the disc 7 slides to both sides along the inner wall of the warehouse body 2 while pushing the baffle 13 to move. The baffle 13 will drive the material receiving tube 14 and the rotating plate 15 to move at the same time, so that the material receiving tube 14 and the guide groove 9 rotate in the opposite direction, and the moving part 10 is used to pull the push rod 11 to reset. Then the push rod 11 will drive the baffle 13, the material receiving tube 14 and the rotating plate 15 to move in the opposite direction at the same time. During the movement, the bottom end of the rotating plate 15 is against the inner wall of the slot 12, thereby rotating in the opposite direction and fitting with the bottom end of the material receiving tube 14. When the material receiving tube 14 is aligned with the storage bin 5, the driving motor 6 is stopped.

[0032] Example 3: The technical content disclosed in this embodiment is a further improvement made on the basis of the above-mentioned embodiment 1 and embodiment 2. Due to the poor fluidity of the material, in order to further solve this technical problem, this technical solution is as follows: Figure 3-Figure 5As shown, an auxiliary unloading component of the metering device is disclosed, in which a piston plate 17 is slidably connected to the storage bin 5, the top of the rotating shaft 8 extends through the bin body 2, and a threaded rod 16 is fixedly connected to the rotating shaft 8, a collar 20 is provided on the outside of the threaded rod 16, and a connecting frame 18 is fixedly connected to the collar 20, and a piston rod 19 is fixedly connected to the bottom end of the connecting frame 18, the collar 20 is threadedly connected to the threaded rod 16, and two connecting frames 18 on the collar 20 are symmetrically arranged, and the piston rods 19 at the bottom ends of the two connecting frames 18 are aligned with the storage bin 5, the bottom end of the piston rod 19 extends through the storage bin 5 and is fixedly connected to the piston plate 17, and the piston rod 19 is slidably connected to the storage bin 5, and the piston plate 17 is located above the discharge port on the storage bin 5.

[0033] In this technical solution, Figure 3 As shown, by utilizing the arrangement of the collar 20 and the threaded rod 16, the threaded rod 16 will engage and drive the collar 20 to move when rotating, thereby driving the connecting frame 18 and the piston rod 19 to move synchronously through the collar 20, and the piston rod 19 will push the piston plate 17 to move downward in the storage bin 5, exerting pressure on the raw materials in the storage bin 5, reducing the blockage and stagnation of the raw materials, and allowing the materials to be smoothly received in the material receiving pipe 14, thereby improving efficiency.

[0034] It uses Figure 4 and Figure 5 The technical solution shown is that, first, when the disc 7 is reset and rotated, the receiving tube 14 will be aligned with the opening at the bottom end of the storage bin 5, and thus fall. At this time, the rotating shaft 8 will rotate with the disc 7, and then the rotating shaft 8 will drive the threaded rod 16 to rotate, so that the threaded rod 16 engages and drives the ring 20 to move downward, and the ring 20 will drive the connecting frame 18 to move downward, so that the connecting frame 18 pushes the piston rod 19 to move, and the piston rod 19 will slide downward along the inner wall of the storage bin 5 while pushing the piston plate 17 to move, so that the piston plate 17 is used to move downward in the storage bin 5, and the raw materials in the storage bin 5 are pressurized, so that the raw materials can fall into the receiving tube 14 more quickly.
