[0022] Please refer to Figure 2 As shown in the figure, the adjusting mechanism includes a sluice gate 2. Rectangular grooves 3 are evenly opened inside the sluice gate 2. A rectangular hole 101 is opened at the bottom end inside the hopper 1. A fixed seat 4 is fixed on one side of the hopper 1. A slide bar 5 is inserted and fixed inside the fixed seat 4. Symmetrical sliding seats 6 are fixed at one end of the sluice gate 2. A rotating seat 7 is fixed on the other side of the hopper 1. A lead screw 8 is rotatably inserted inside the rotating seat 7. A turntable 9 is fixed at one end of the lead screw 8. Symmetrical connecting seats 10 are fixed at the other end of the sluice gate 2. The connecting seats 10 are rotatably connected to the lead screw 8. The sliding seats 6 are slidably connected to the slide bar 5. The sluice gate 2 is slidably connected to the bottom end inside the hopper 1. During operation, when encountering the problem that the existing feeding control device is prone to blockage, through the structure of the adjusting mechanism, rotate the turntable 9 to drive the lead screw 8 to rotate. Then, with the cooperation of the connecting seat 10, push the sluice gate 2 to slide on the slide bar 5 with the cooperation of the sliding seat 6, so as to change the size of the gap after the rectangular grooves 3 and the rectangular hole 101 are staggered, realizing the function of adjusting the feeding flow rate. Moreover, the structure of multiple rectangular grooves 3 and rectangular hole 101 makes the material less likely to be blocked during transportation.

[0023] Please refer to Figure 3 As shown in the figure, the detection mechanism includes a connecting seat 10. A support 11 is fixed on the top side of the connecting seat 10. The support 11 is closely attached to the side of the hopper 1 and is slidably connected to the hopper 1. An indicating needle 12 is fixed at the center position on the top side of the support 11. A scale groove 13 is opened on the side of the hopper 1. The indicating needle 12 is located on one side of the scale groove 13. Limiting grooves 14 are symmetrically opened inside the hopper 1. During operation, when encountering the problem that the material flow rate cannot be accurately adjusted, through the structure of the detection mechanism, when rotating the turntable 9 to adjust the material feeding flow rate, the connecting seat 10 drives the support 11 to slide on the side of the hopper 1. At this time, the indicating needle 12 on its top side slides linearly on the surface of the scale groove 13. By observing the position of the indicating needle 12 in the scale groove 13, the size of the gap after the rectangular grooves 3 and the rectangular hole 101 are staggered is measured, so as to accurately control the flow rate during material feeding and make the device more convenient to use.

[0024] Please refer to Figure 4As shown in the figure, the cleaning mechanism includes a limit groove 14, a scraper 15 is slidably installed inside the limit groove 14, connecting rods 16 are symmetrically fixed to the side of the limit groove 14, the connecting rods 16 are closely attached to the inner side of the hopper 1 and are slidably connected to the hopper 1. One end of the connecting rod 16 is fixed with a movable door 17, the movable door 17 is buckled on one side of the hopper 1, a handle 18 is fixed to the side of the movable door 17, and a latch 19 is rotatably installed on the side of the hopper 1, and the latch 19 is buckled on the top end of the side of the movable door 17. During operation, when there is a problem that large particle materials appear during the feeding process, resulting in blockage of the feeding device, through the structure of the cleaning mechanism, rotate the latch 19 to pull it away from the side of the movable door 17, pull the handle 18 to open the movable door 17. At this time, with the cooperation of the connecting rod 16, pull the scraper 15 to slide along the limit groove 14. Since the scraper 15 is closely attached to and slidably connected to the inner bottom end of the hopper 1, at this time, the scraper 15 scrapes and outputs the large particle materials inside the hopper 1, thereby preventing the feeding device from being blocked.

[0025] Please refer to Figure 5 As shown in the figure, a trough plate 20 is fixed to the bottom end of the side of the hopper 1, and the trough plate 20 is located at the bottom side of the movable door 17. During operation, when there is a problem that waste materials are easily attached to the surface of the slide rod 5 and are not convenient to clean, through the structure of the trough plate 20, the large particle waste materials blocked inside the hopper 1 can be conveyed to the surface of the trough plate 20 and discharged, so as to ensure the normal operation of the magnetic separator and improve its working efficiency.

[0026] Working principle: The magnetic separator is a screening device that uses magnetic force to remove iron powder from powdery granules. It is widely used in the iron removal operations of materials such as coal, non-metallic minerals, and building materials. During the processing of the magnetic separator, it is necessary to control the feeding flow rate through its feeding device to ensure the normal operation of the magnetic separator. The existing feeding control device adjusts the feeding flow rate by controlling the opening size of the gate plate. During use, the material is easily blocked at the feeding port, resulting in the inability of the magnetic separator to operate normally. To solve this problem, by setting an adjusting mechanism and a cleaning mechanism, rotate the turntable 9, which drives the screw rod 8 to rotate. Thus, with the cooperation of the connecting seat 10, the gate plate 2 is pushed to slide on the sliding rod 5 with the cooperation of the sliding seat 6. At this time, the connecting seat 10 drives the bracket 11 to slide on the side of the hopper 1. At this time, the indicating needle 12 on its top slides linearly on the surface of the scale groove 13. By observing the position of the indicating needle 12 in the scale groove 13, the size of the gap after the rectangular groove 3 and the rectangular hole 101 are staggered is measured, thereby changing the size of the gap after the rectangular groove 3 and the rectangular hole 101 are staggered. At this time, the material is added from the top of the hopper 1 and is detected and processed by the magnetic separator. If large-particle materials enter and block the inside of the hopper 1 during feeding, rotate the clamping block 19 to pull it away from the side of the movable door 17, and pull the handle 18 to open the movable door 17. At this time, with the cooperation of the connecting rod 16, the scraping plate 15 is pulled to slide along the limiting groove 14. Since the scraping plate 15 is in close contact with and slidably connected to the bottom end inside the hopper 1, at this time, the scraping plate 15 scrapes and outputs the large-particle materials inside the hopper 1, enabling the device to operate normally. The material is conveyed from the bottom of the hopper 1 to the required position, solving the problem that the existing feeding device is easily blocked, resulting in a reduction in the working efficiency of the magnetic separator.
