[0021] The support frame 1 is used for supporting the spiral feeding pipe 2, ensuring the stability of the spiral feeding pipe 2 during use of the device. The spiral feeding pipe 2 is used for conveying the protective slag. The inside of the spiral feeding pipe 2 is provided with an electric rod with spiral blades on the side wall. During rotation of the electric rod, the protective slag in the inside of the spiral feeding pipe 2 is conveyed to the top by the electric rod. The storage bin 3 is used for storing the protective slag. The storage bin 3 is installed on the top surface groove of the feeding inlet of the spiral feeding pipe 2. The installation mode of the storage bin 3 facilitates replacement of the storage bin 3 by the user, improving the efficiency of the user in supplementing the protective slag. The top surface groove of the feeding inlet of the spiral feeding pipe 2 is provided with a support rod. The end surface of the storage bin 3 is provided with a groove matched with the support rod. The cooperation between the end surface groove of the storage bin 3 and the matched support rod ensures the stability of the storage bin 3 after installation on the feeding inlet of the spiral feeding pipe 2. The bottom of the storage bin 3 is slidably provided with a sliding plate 31. When the protective slag is added to the inside of the spiral feeding pipe 2, the sliding plate 31 is pulled to release the sealing of the storage bin 3 by the sliding plate 31. The protective slag falls into the inside of the spiral feeding pipe 2. The side wall of the storage bin 3 is provided with a groove matched with the sliding plate 31. The cooperation between the sliding plate 31 and the matched groove plays a guiding and limiting role, ensuring the stability of the sliding plate 31 during movement and installation on the storage bin 3. The end surface of the sliding plate 31 is provided with a protrusion. The end surface protrusion of the sliding plate 31 plays a limiting role, avoiding disengagement of the sliding plate 31 from the storage bin 3 during movement, and ensuring the stability of the sliding plate 31. The temporary storage bin 4 is used for temporarily storing the protective slag. The electric sealing plate 41 can seal the temporary storage bin 4, avoiding the protective slag in the spiral feeding pipe 2 from falling into the temporary storage bin 4, and affecting the quantitative use of the protective slag by the device. The weighing rotating plate 45 can seal the bottom opening of the moving frame 44. The weighing rotating plate 45 is provided with a weighing piece. The weighing rotating plate 45 can weigh the protective slag falling into the temporary storage bin 4, realizing the quantitative use of the protective slag by the device. When the protective slag is used quantitatively, the sealing of the temporary storage bin 4 by the electric sealing plate 41 is released. The protective slag is conveyed into the temporary storage bin 4 by the spiral feeding pipe 2. The protective slag in the temporary storage bin 4 is weighed by the weighing rotating plate 45. After the weight of the protective slag in the temporary storage bin 4 reaches the requirement, the electric sealing plate 41 is controlled to be elongated to seal the temporary storage bin 4, realizing the quantitative use of the protective slag. The top surface of the moving frame 44 is inclined. The inclined top surface of the moving frame 44 can avoid accumulation of the protective slag on the top surface of the moving frame 44, ensuring that the protective slag in the temporary storage bin 4 can be completely discharged from the temporary storage bin 4. The protective slag in the temporary storage bin 4 can be discharged from the device through cooperation of the feeding pipe 5 and the discharging mechanism 6. The position of the mounting frame 63 can be adjusted by adjusting the length of the electric telescopic rod 64. The discharging plate 61 is installed on the electric threaded rod 62 through threads. When the electric threaded rod 62 is started, the discharging plate 61 moves along the electric threaded rod 62 under the action of threads, realizing adjustment of the position of the discharging plate 61. Adjustment of the position of the device for discharging the protective slag is realized by adjusting the positions of the discharging plate 61 and the mounting frame 63.The side wall of the blanking plate 61 is provided with a protrusion, and the inner wall of the mounting frame 63 is provided with a groove matched with the side wall protrusion of the blanking plate 61. The cooperation of the side wall protrusion of the blanking plate 61 and the matched groove plays a limiting role, which ensures that the blanking plate 61 will not be rotated with the electric threaded rod 62 during movement, and ensures the stability of the blanking plate 61 during movement. The feeding pipe 5 passes through the limiting frame 52. During the movement of the mounting frame 63, the feeding pipe 5 will push the limiting frame 52, and the pushed limiting frame 52 will stretch the elastic expansion rod 51. During the movement of the feeding pipe 5 with the moving mounting frame 63, the feeding pipe 5 will slide on the limiting frame 52. The sliding limiting frame 52 and the stretched elastic expansion rod 51 ensure the stability of the feeding pipe 5 while avoiding the feeding pipe 5 hindering the movement of the blanking plate 61. The feeding pipe 5 has a certain strength, which ensures that the feeding pipe 5 will not deform greatly during the process of pushing the limiting frame 52, and ensures that the feeding of the protective slag will not be affected. During the movement of the blanking plate 61 along the electric threaded rod 62, the feeding pipe 5 slides along the limiting frame 52 under the driving of the blanking plate 61, which ensures that the movement of the blanking plate 61 will not be hindered. When the blanking mechanism 6 returns to the original position, the elastic expansion rod 51 automatically restores to the original state, and the elastic expansion rod 51 that restores to the original state will drive the limiting frame 52 and the feeding pipe 5 to return to the original position, which ensures the stability of the feeding pipe 5.

[0022] Specifically, the temporary storage bin 4 is provided with two electric winding drums 43, the pull lines of the electric winding drums 43 are connected with the moving frame 44, the pull lines of the electric winding drums 43 are provided with protrusions at the opening of the slot of the temporary storage bin 4, and the edges of the inner wall protrusions of the temporary storage bin 4 are provided with rollers.

[0023] When the electric winding drum 43 is started, the electric winding drum 43 will wind the pull line, and the wound pull line will move the moving frame 44, thereby realizing the adjustment of the position of the moving frame 44. When the moving frame 44 moves, the amount of protective slag that the temporary storage bin 4 can accommodate changes, which is convenient for the user to take the protective slag quantitatively. The inner wall protrusions of the temporary storage bin 4 support the pull line wound on the electric winding drum 43, the shape of the inner wall protrusions of the temporary storage bin 4 ensures that the pull line will not contact the inner wall of the temporary storage bin 4 during movement, thereby reducing the damage of the pull line during movement. The rollers arranged at the edges of the inner wall protrusions of the temporary storage bin 4 will rotate during the movement of the pull line, thereby reducing the wear of the pull line during movement and prolonging the service life of the pull line. The slot through which the pull line wound on the electric winding drum 43 penetrates is in a downward inclined state, thereby avoiding the protective slag from being unable to be discharged after entering the slot penetrated by the pull line.

[0024] Specifically, the side wall of the temporary storage bin 4 is provided with a vibration motor 47.

[0025] The vibration motor 47 can vibrate the temporary storage bin 4. The vibrating temporary storage bin 4 can accelerate the falling speed of the protective slag, improve the falling speed of the protective slag into the temporary storage bin 4, and improve the speed of the protective slag in the moving frame 44 out of the moving frame 44, so as to ensure the smoothness of the protective slag in the moving process. The vibration motor 47 also serves to vibrate the protective slag in the temporary storage bin 4, thereby increasing the amount of protective slag that can be accommodated in the temporary storage bin 4.

[0026] Specifically, the side wall of the temporary storage bin 4 is provided with a support frame 42, and the electric sealing plate 41 is installed on the support frame 42.

[0027] The support frame 42 serves to support the electric sealing plate 41, thereby ensuring the stability of the electric sealing plate 41 after being installed on the temporary storage bin 4. The support frame 42 is divided into two parts. One part of the support frame 42 is in the shape of a support plate, and the main body of the electric sealing plate 41 is arranged on the support frame 42 in the shape of a support plate. The support frame 42 in the shape of a support plate serves to support the main body of the electric sealing plate 41, thereby ensuring the stability of the electric sealing plate 41 during use of the device. The other part of the support frame 42 is in the shape of a frame body that cooperates with the temporary storage bin 4. The side wall of the temporary storage bin 4 is provided with a groove that cooperates with the frame body of the support frame 42. The cooperation between the groove of the side wall of the temporary storage bin 4 and the frame body of the support frame 42 serves to limit the position, thereby ensuring the stability of the frame body of the support frame 42 after being arranged on the temporary storage bin 4. One end of the main body of the electric sealing plate 41 is arranged on the frame body of the support frame 42. The cooperation between the two parts of the support frame 42 and the electric sealing plate 41 ensures the support effect of the support frame 42 on the electric sealing plate 41.

[0028] Specifically, the moving frame 44 is connected to the bottom opening of the temporary storage bin 4 through a connecting pipe 46.

[0029] After the position of the moving frame 44 is adjusted, the distance between the bottom opening of the moving frame 44 and the bottom opening of the temporary storage bin 4 changes. During the movement of the moving frame 44, the moving frame 44 will elongate the connecting pipe 46, so as to avoid the protective slag in the moving frame 44 from entering the position between the bottom of the moving frame 44 and the bottom of the temporary storage bin 4 during the movement of the moving frame 44, avoid the protective slag from adhering to the side wall between the bottom of the moving frame 44 and the bottom of the temporary storage bin 4, and facilitate the user to clean the temporary storage bin 4. The connecting pipe 46 is elastic. When the moving frame 44 returns to the original position, the connecting pipe 46 will automatically contract, thereby avoiding the connecting pipe 46 from hindering the movement of the moving frame 44.

[0030] Specifically, the inner wall of the limiting frame 52 is provided with a plurality of rollers 53, and the edge of the limiting frame 52 is in the shape of an arc.

[0031] The rolling drum 53 is rotated during the movement of the material conveying pipe 5 in the limiting frame 52, the rotating rolling drum 53 reduces the friction force suffered by the material conveying pipe 5 during the movement, reduces the abrasion of the material conveying pipe 5 during the use of the device, the material conveying pipe 5 is in contact with the edge of the limiting frame 52 during the movement, the shape of the edge of the limiting frame 52 reduces the abrasion of the material conveying pipe 5 during the movement, and the service life of the material conveying pipe 5 is prolonged.

[0032] Specifically, the side wall of the storage bin 3 is provided with an observation window 32.

[0033] The observation window 32 is used for the user to observe the amount of protective slag stored in the storage bin 3, so that the user can replace the storage bin 3 in time.
