Description

Technical Field

[0001] This application relates to the field of metal smelting equipment technology, and in particular to an automatic feeding and conveying device for raw materials in niobium ingot production. Background Technology

[0002] In the production of niobium ingots, the feeding and conveying of raw materials is crucial. Traditional methods for feeding raw materials in niobium ingot production mostly rely on manual feeding or simple mechanical feeding devices. Manual feeding is not only inefficient and labor-intensive, making it difficult to meet the demands of large-scale production, but also poses significant safety risks during operation. Existing mechanical feeding devices have low levels of automation, making it difficult to precisely control the feeding position and quantity during material conveying, easily leading to material spillage, waste, environmental pollution, and affecting the quality and stability of subsequent niobium ingot production. Furthermore, existing devices often require additional power to open and close the hopper, increasing energy consumption and equipment costs. Utility Model Content

Detailed Implementation

[0024] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0025] like Figure 1-6 As shown, this utility model discloses a technical solution: an automatic feeding and conveying device for niobium ingot production raw materials, including a support frame and a material box 11 slidably connected to the support frame. The support frame is composed of a base 1, a vertical plate 2, and a top frame 3 vertically fixedly connected to form a stable support structure.

[0026] A lifting drive assembly for raising and lowering the material box 11 is rotatably connected to two upright plates 2. This lifting drive assembly includes a drive motor, a driving gear 5, a driven gear 7, a timing belt 8, an upper push rod 9, and a lower push rod 10. The driving gear 5 and driven gear 7 are rotatably connected to both sides of the upright plate 2 via a first shaft 4 and a second shaft 6. One end of the first shaft 4 passes through the upright plate 2 and is fixed to the output end of the drive motor. The timing belt 8 surrounds the driving gear 5 and driven gear 7 on the same side, and the upper push rod 9 and lower push rod 10 are vertically fixed to the outer surface of the timing belt 8. The material box 11 has an upper support rod 12 and a lower support rod 13 on both sides. The upper push rod 9 and lower push rod 10 respectively abut against the bottom of the upper support rod 12 and lower support rod 13. The drive motor drives the driving gear 5 to rotate, and through the timing belt 8, the material box 11 is stably raised and lowered.

[0027] A gate 16 is movably connected to the feed inlet of the material box 11. The two sides of the material box 11 are elastically connected to the gate 16 via return springs 23. A guide post 15 is fixed on the upright plate 2. The guide post 15 restricts the displacement trajectory of the gate 16, so that the feed inlet automatically opens when the material box 11 rises. Specifically, a lower support plate 21 is fixed on both sides of the material box 11, and an upper support plate 22 is fixed on the gate 16. The two ends of the return spring 23 abut against the lower support plate 21 and the upper support plate 22 respectively. A limiting post 24 is provided on the lower support plate 21. The return spring 23 is sleeved on the limiting post 24, and the top of the limiting post 24 penetrates through the upper support plate 22.

[0028] A guide plate 25 is hinged to the end face of the gate 16 away from the material box 11. A transmission assembly for controlling the rotation of the guide plate 25 is provided on the gate 16. The transmission assembly includes a linkage gear 32, a transmission shaft 31, and a sector gear 30. A limiting groove 29 is provided inside the guide plate 25, and the sector gear 30 is fixed to the hinge shaft of the guide plate 25. A shaft hole is provided on the gate 16, and the linkage gear 32 is installed in the shaft hole via the transmission shaft 31 and meshes with the sector gear 30. A guide rail 33 is provided along the edge of the material inlet of the material box 11, and a rack 34 is provided on the inner wall of the guide rail 33. The linkage gear 32 meshes with the rack 34, so that when the gate 16 moves, the linkage gear 32 rotates along the rack 34, driving the guide plate 25 to unfold.

[0029] The upright plate 2 is equipped with a stroke control mechanism for adjusting the lifting stroke of the material box 11. The upright plate 2 has a strip-shaped guide hole 14, and one end of the upper support rod 12 and the lower support rod 13 are slidably connected within the guide hole 14. The stroke control mechanism is integrated within the guide hole 14. The stroke control mechanism includes a fixed block 35, a sliding block 36, a buffer spring 37, a first contact 38, and a second contact 39. The fixed block 35 is fixed within the guide hole 14, and the sliding block 36 is elastically connected to the fixed block 35 via the buffer spring 37. The first contact 38 and the second contact 39 are respectively located on the opposite end faces of the fixed block 35 and the sliding block 36, and are electrically connected to the control unit. When the sliding block 36 is pressed, causing the first contact 38 to contact the second contact 39, the control unit cuts off the power to the drive motor.

[0030] In addition, sliders 17 are fixed on both sides of the material box 11, and slide rails 18 are provided on the sliders 17. Locking screws 19 are provided on the side of the gate plate 16, and the ends of the locking screws 19 are inserted into the slide rails 18, which facilitates the installation, disassembly and maintenance of the gate plate 16. Multiple sets of hinge slots 26 are provided on the gate plate 16 and the guide plate 25. Hinge pins 27 and hinge arms 28 are provided in the hinge slots 26. The guide plate 25 is rotatably connected to the hinge pins 27 through the hinge arms 28, ensuring the flexibility and stability of the rotation of the guide plate 25.

[0031] This application provides an automatic feeding and conveying device for niobium ingot production raw materials. When niobium ingot production raw materials need to be fed, the drive motor is started, which drives the drive gear 5 to rotate. The drive gear 5 drives the driven gear 7 to rotate through the synchronous belt 8, thereby moving the synchronous belt 8. The upper push rod 9 and lower push rod 10 on the synchronous belt 8 push the upper support rod 12 and lower support rod 13 on both sides of the material box 11, causing the material box 11 to rise along the guide hole 14.

[0032] During the ascent of the material container 11, the gate 16, restricted by the guide post 15, cannot rise with the material container 11. At this time, the return spring 23 is compressed, and the feed inlet of the material container 11 gradually opens. Simultaneously, the gate 16 moves relative to the material container 11, and the linkage gear 32 rotates along the rack 34 within the guide rail 33. The linkage gear 32 drives the sector gear 30 to rotate, causing the guide plate 25 to open at a certain angle relative to the gate 16 around the hinge axis, preparing for the material conveying.

[0033] When the material container 11 rises to the predetermined position, the upper support rods 12 and lower support rods 13 on both sides of the material container 11 push the sliding block 36 towards the fixed block 35. When the sliding block 36 moves to the point where the first contact 38 contacts the second contact 39, the control unit receives a signal, cuts off the power to the drive motor, and the material container 11 stops rising. At this time, the raw material smoothly enters the subsequent equipment through the open feed port and the unfolded guide plate 25.

[0034] After loading is completed, the drive motor reverses, and the loading box 11 begins to descend. During the descent, the return spring 23 gradually returns to its original state, pushing the gate 16 to close the feed inlet of the loading box 11. At the same time, the guide plate 25 gradually retracts under the action of the linkage gear 32 and the sector gear 30, returning to its initial position. When the loading box 11 descends to its initial position, one loading and conveying cycle is completed, and it awaits the next loading command.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
