This solves the problem that in the prior art, when the smelting furnace is actually pouring the molten metal, there is a certain distance between the discharge port 6 and the collecting container. Under the action of gravity acceleration, the molten metal will splash everywhere after entering the collecting container, causing a certain impact on the safety of the surrounding workers. The collecting container can be fixed by setting the fixing component to avoid the movement of the collecting container during the process of pouring the molten metal, which may cause the molten metal to pour out. The stability of the device during use is improved. By setting the lifting component, the sealing cover 9 can be driven to open or close when the protective box 5 slides, avoiding the situation that the sealing cover 9 is inconvenient to manually open and close due to the setting of the protective box 5. The operation is simple and easy to use. Start the motor 3 to drive the motor 3 to drive the furnace 4 to flip, so that the end of the drainage trough 7 away from the discharge port 6 is located above the collecting container.

[0027] In this embodiment, wheels are provided at the four corners of the bottom end of the base 1, which can facilitate the movement of the device and thus the transfer of the device, thereby improving the convenience of the device when in use. The wheels are self-locking universal wheels, which can fix the position of the device and avoid the device from moving during use.

[0028] In this embodiment, the fixing assembly includes a first fixing plate 10, a second fixing plate 11, a cylinder 12 and a clamping plate 13. The first fixing plate 10 and the second fixing plate 11 are respectively arranged on the front and rear sides of the top of the base 1, and the two cylinders 12 are respectively arranged on the side where the first fixing plate 10 and the second fixing plate 11 are close to each other. The two clamping plates 13 are respectively arranged at the ends where the two cylinders 12 are close to each other. The collecting container is placed between the two clamping plates 13, and the two cylinders 12 are started to extend the output ends of the two cylinders 12, so that the two clamping plates 13 slide toward the middle of the top of the base 1 at the same time, so that the two clamping plates 13 clamp the collecting container tightly and fix it.

[0029] In this embodiment, the sides of the two clamping plates 13 that are close to each other are both matched with the outer wall of the molten metal collecting container, which can improve the fixing effect of the fixing component.

The top of the moving block 16 is fixedly connected to the bottom end of the protection box 5. One end of the two electric push rods 14 is respectively hinged to the front and back sides of the outer wall of the furnace 4, and the other ends of the two electric push rods 14 are respectively hinged to the left and right sides of the outer wall of the protection box 5. Start the electric push rod 14 to extend the output end of the electric push rod 14, and then the protection box 5 slides along a straight line toward the direction close to the drainage groove 7 under the limiting action of the slide groove 15 and the moving block 16. Since the drainage groove 7 of the collecting container is in a vertical state at this time, when the protection box 5 extends out of one side of the furnace 4, it can wrap the three sides of the collecting container.

[0031] In this embodiment, the inner cavity of the slide groove 15 is matched with the outer wall of the moving block 16 and both are in a "T" shape, so that the moving block 16 can always remain embedded in the inner cavity of the slide groove 15, preventing the protective box 5 from flipping or rising and falling when the output end of the electric push rod 14 is extended, so that the protective box 5 always slides along the top of the furnace 4.

[0032] In this embodiment, the lifting assembly includes a transmission assembly, a screw 17, a slider 20, a fixed seat 21, a connecting rod 22 and a limit assembly. The two ends of the screw 17 are rotatably connected to the inner cavity of the fixing frame 8 through bearings. The transmission assembly is arranged at the top of the inner cavity of the protective box 5 and is fixedly sleeved on the outer wall of the screw 17. The two sliders 20 are respectively screwed on the outer wall of the screw 17. The fixed seat 21 is arranged in the middle of the top of the sealing cover 9. One end of the two connecting rods 22 is respectively hinged to the bottom end of the two sliders 20, and the other end of the two connecting rods 22 is respectively hinged to the top of the fixing seat 21. The limit assembly The component is arranged at the top of the inner cavity of the fixing frame 8 and is fixedly connected to the outer walls of the two sliders 20. When the protective box 5 slides, the rack 18 drives the gear 19 to drive the screw rod 17 to rotate. Since the threads on both sides of the outer wall of the screw rod 17 are arranged relatively to each other, when the screw rod 17 rotates, the two sliders 20 can slide toward the two ends of the screw rod 17 at the same time under the limiting action of the limiting groove 23 and the limiting block 24, so that the two connecting rods 22 pull the fixing seat 21 and the sealing cover 9 to slide upward along a straight line under the limiting action of multiple telescopic rods 25, so that the sealing cover 9 releases the seal of the discharge port 6 and the drainage groove 7.

[0033] In this embodiment, the transmission assembly includes a rack 18 and a gear 19. The rack 18 is fixedly connected to the top of the inner cavity of the protective box 5. The gear 19 is fixedly sleeved on the middle of the outer wall of the screw rod 17 and extends to the top of the fixed frame 8 to engage with the rack 18. When the protective box 5 drives the rack 18 to slide, the gear 19 is started to drive the screw rod 17 to rotate.

[0034] In this embodiment, the threads on both sides of the outer wall of the screw rod 17 are arranged relative to each other, so that when the screw rod 17 rotates, the left and right sides of its outer wall generate relative thread rotation forces, so that the two sliders 20 slide relatively at the same time under the limiting action of the limiting groove 23 and the limiting block 24.

[0035] In this embodiment, the limit assembly includes a limit groove 23 and a limit block 24. The two limit grooves 23 are both opened at the top of the inner cavity of the fixed frame 8. The two limit blocks 24 can be slidably embedded in the inner cavity of the two limit grooves 23 and are respectively fixedly connected to the top of the two sliders 20. Under the interaction between the limit groove 23 and the limit block 24, the slider 20 can be prevented from rotating with the screw rod 17 when the screw rod 17 rotates, thereby improving the stability of the lifting assembly when in use.

[0036] The use method and advantages of the utility model: When in use, the working process is as follows:

[0037] When pouring molten metal, first, place the collecting container between the two clamps 13, start the two cylinders 12, extend the output ends of the two cylinders 12, and then slide the two clamps 13 toward the middle of the top of the base 1 at the same time, so that the two clamps 13 clamp the collecting container and fix it. At this time, start the motor 3, so that the motor 3 drives the furnace 4 to flip, so that the end of the drainage trough 7 away from the discharge port 6 is located above the collecting container, start the electric push rod 14, extend the output end of the electric push rod 14, and then slide the protective box 5 along a straight line toward the drainage trough 7 under the limiting action of the slide 15 and the moving block 16. Since the drainage trough 7 of the collecting container is in a vertical state at this time, when When the protective box 5 extends out of one side of the furnace 4, it can wrap the three sides of the collecting container. When the protective box 5 slides, the rack 18 drives the gear 19 to drive the screw 17 to rotate. Since the threads on both sides of the outer wall of the screw 17 are relatively arranged, when the screw 17 rotates, the two sliders 20 can slide toward the two ends of the screw 17 at the same time under the limiting action of the limiting groove 23 and the limiting block 24, so that the two connecting rods 22 pull the fixed seat 21 and the sealing cover 9 to slide upward along a straight line under the limiting action of multiple telescopic rods 25, so that the sealing cover 9 releases the seal on the discharge port 6 and the drainage groove 7, and under the action of gravity, the molten metal can enter the interior of the collecting container to complete the collection of the molten metal.
