Specific implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Referring to Figure 1 , 2 , 3 shown, an embodiment provided by the present utility model: A granular material conveying device for a smelting furnace includes a rail 1, a transport vehicle 2 is slidably connected to the top of the rail 1, a storage bin 4 is arranged on the top of the transport vehicle 2, a pushing plate 9 is slidably connected to the inner wall of the storage bin 4, a bidirectional motor 10 is fixedly connected to the left part of the lower side of the inner wall of the transport vehicle 2, a dust-proof plate 14 is threadedly connected to the outer wall of the sub threaded rod 13, mounting plates 15 are connected to the front and rear sides of the inner wall of the transport vehicle 2 through a disassembly assembly, and a feeding port 5 is opened at the top of the storage bin 4. The right end of the sliding frame 6 is fixedly connected to a motor 7, the driving end of the motor 7 penetrates the inner wall of the sliding frame 6 and is fixedly connected to a main threaded rod 8, the outer wall of the sliding frame 6 is slidably connected to the right side of the inner wall of the storage bin 4, the outer wall of the main threaded rod 8 is threadedly connected to the inner wall of the storage bin 4, and a sub bevel gear 12 located at the bottom end of the sub threaded rod 13, the main bevel gear 11 and the sub bevel gear 12 are meshed with each other, and the bottom end of the sub bevel gear 12 is respectively rotatably connected to the front and rear parts of the lower side of the inner wall of the transport vehicle 2.

[0026] Specifically, when adding materials into the storage bin 4, first start the bidirectional motor 10 through the controller 3. The bidirectional motor 10 drives the main bevel gears 11, secondary bevel gears 12, and secondary threaded rods 13 at both driving ends to rotate. The secondary threaded rod 13 drives the dust-proof plate 14 to move upward to block the discharge port of the storage bin 4. Then add materials into the storage bin 4 through the feed port 5. After the addition is completed, drive the rotating wheel to rotate through the power driving end, so that the transport vehicle 2 moves to the left. When the transport vehicle 2 moves to the leftmost side, control the bidirectional motor 10 to reverse and start the motor 7 through the controller 3. The bidirectional motor 10 reverses to drive the dust-proof plate 14 to descend. At the same time, the motor 7 drives the main threaded rod 8 to rotate, so that the main threaded rod 8 rotates on the inner wall of the storage bin 4, thereby driving the sliding frame 6 to slide to the left. At the same time, the sliding frame 6 drives the pushing plate 9 to slide to the left to push the internal materials to the left and add the materials to the furnace through the guiding plate. This not only can lift the dust-proof plate 14 upward to block the discharge port when adding materials into the storage bin 4, avoiding dust flying out and preventing harm to the workers' bodies, but also does not require workers to manually discharge materials during discharging, improving work efficiency and reducing the workload of workers.

[0027] Reference Figure 1 、 2 As shown in FIGS. 4, opposite ends of the connecting rods 17 are fixedly connected with clamping blocks 19 respectively. Opposite ends of the clamping blocks 19 are fixedly connected with springs 18 respectively corresponding to the outer sides of the connecting rods 17. Slots 16 are respectively formed at the front and rear ends of the mounting plate 15. Opposite ends of the springs 18 are fixedly connected to the front and rear sides of the inner wall of the transport vehicle 2 respectively. Outer walls of the clamping blocks 19 are arranged on the inner walls of the slots 16. The shape of the clamping blocks 19 fits the slots 16. A plurality of rotating wheels are arranged on the inner wall of the transport vehicle 2. Inner walls of the rotating wheels are respectively arranged on the outer wall of the track 1. The left end of the transport vehicle 2 is fixedly connected with a guiding plate. The left side of the front end of the transport vehicle 2 is fixedly connected with a controller 3. The controller 3 is electrically connected to the motor 7 and the bidirectional motor 10.

[0028] Specifically, when it is necessary to clean the inner wall of the storage bin 4 or replace the storage bin 4, only need to pull the connecting rods 17 at the front and rear ends outward to take out the clamping blocks 19 from the slots 16, then the storage bin 4 can be taken out upward. During installation, only need to align the mounting plate 15 with the groove at the top of the transport vehicle 2 first, pull the connecting rods 17 outward, then move the mounting plate 15 downward to align the slots 16 with the clamping blocks 19, and then release the connecting rods 17. The clamping blocks 19 are snapped into the slots 16 by the elastic force of the springs 18 to limit the mounting plate 15, so that the storage bin 4 can be installed on the transport vehicle 2. The operation is simple, which is convenient for workers to disassemble the storage bin 4 from the transport vehicle 2, convenient for cleaning a large amount of residual materials inside, and avoiding the adhesion of materials or affecting the service life of the device during use.

[0029] Working principle: First, when adding materials into the storage bin 4, the bidirectional motor 10 is started by the controller 3 first. The bidirectional motor 10 drives the main bevel gears 11 at both driving ends to rotate. The main bevel gears 11 drive the secondary bevel gears 12 to rotate. The secondary bevel gears 12 drive the secondary threaded rods 13 to rotate. The secondary threaded rods 13 drive the dust-proof plate 14 to move upward to block the discharge port of the storage bin 4. Then, materials are added into the storage bin 4 through the feed port 5. After the addition is completed, the rotating wheel is driven to rotate by the power drive end, so that the transport vehicle 2 moves to the left. When the transport vehicle 2 moves to the leftmost position, the controller 3 controls the bidirectional motor 10 to reverse and starts the motor 7. The bidirectional motor 10 reverses, driving the dust-proof plate 14 to descend. At the same time, the motor 7 drives the main threaded rod 8 to rotate, causing the main threaded rod 8 to rotate on the inner wall of the storage bin 4, thereby driving the sliding frame 6 to slide to the left. At the same time, the sliding frame 6 drives the pushing plate 9 to slide to the left, pushing the internal materials to the left and adding the materials to the furnace through the guide plate. At the same time, when it is necessary to clean the inner wall of the storage bin 4 or replace the storage bin 4, only the connecting rods 17 at the front and rear ends need to be pulled outwards, and the clamping blocks 19 are taken out of the clamping slots 16, then the storage bin 4 can be taken out upwards. During installation, only the mounting plate 15 needs to be aligned with the groove at the top of the transport vehicle 2 first, the connecting rod 17 is pulled outwards, then the mounting plate 15 is moved downwards, the clamping slot 16 is aligned with the clamping block 19, and then the connecting rod 17 is released. The clamping block 19 is clamped into the clamping slot 16 by the elastic force of the spring 18 to limit the mounting plate 15, and then the storage bin 4 can be installed on the transport vehicle 2. The operation is simple.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
