[0023] Referring to Figure 1-Figure 5 , a material distribution cylinder for a magnetic separator, includes a bottom frame 1. A material distribution box 2 is fixedly installed on the top of the bottom frame 1. A feeding funnel 3 is fixedly installed on the top of the material distribution box 2. A discharge port is opened at the bottom of the material distribution box 2. A material distribution roller 18 is rotatably installed in the material distribution box 2. Two limiting boxes 4 are symmetrically and fixedly installed at the bottom of the material distribution box 2. A screen box 5 is arranged between the two limiting boxes 4. The screen box 5 has a U-shaped structure with an upward opening. A plurality of filtering holes are opened at the bottom of the screen box 5. A scraper 20 is slidably installed on the top of the screen box 5. An avoidance hole penetrating through its surface is opened on one side of the scraper 20. A transfer block 21 is slidably installed in the avoidance hole. A chain 16 is arranged in the screen box 5. One end of the chain 16 passes through the outer surface of the transfer block 21 and is fixedly installed with it.

[0024] During use, by setting the scraper 20, the material distribution roller 18 rotates to carry a certain amount of materials for rotational separation and then puts them into the screen box 5. During the continuous rotation of the material distribution roller 18, the chain 16 reciprocally pulls the transfer block 21, thereby driving the scraper 20 to slide along the screen box 5 towards the open ends at both of its ends, so as to clean the upper surface of the filtering holes. In this way, the screen box 5 can be automatically cleaned during the working state, avoiding cleaning it during shutdown, improving the continuous working ability of the equipment, and further improving the working efficiency of magnetic ore separation.

[0025] In this embodiment, the bottoms of the two limit boxes 4 are open structures, and each limit box 4 is linearly and evenly fixed with a plurality of tension springs 31, the top of the screen box 5 is slidably installed in the two limit boxes 4, the bottom ends of each tension spring 31 are fixedly installed with the top of the screen box 5, and the two opposite sides of the screen box 5 are fixedly installed with impact blocks 13, and the two opposite sides of the distribution box 2 are rotatably installed with the first gear 9 and the second gear 12, and the two first gears 9 are connected to the rotation center of both ends of the distribution roller 18 through the connecting shaft through the distribution box 2, and the first gear 9 and the second gear 1 2 meshes, a cam 11 is fixedly installed at the center of one side of each second gear 12, a first support frame 8 is fixedly installed at one side of the distribution box 2, a servo motor 10 is fixedly installed at one side of the first support frame 8, the output end of the servo motor 10 is fixedly installed with the rotation center of one side of the adjacent first gear 9, and both ends of the bottom discharge port of the distribution box 2 are fixedly installed with triangular-shaped blocking blocks 30, both sides of the bottom frame 1 are fixedly installed with second discharge funnels 7, a plurality of distribution cavities 19 are evenly opened on the surface of the distribution roller 18 in a circumferential manner, and a first discharge funnel 6 is fixedly installed at the bottom of the screen box 5.

[0026] When in use, the servo motor 10 intermittently drives the first gear 9 on one side of the distribution box 2 to rotate, thereby driving the distribution roller 18 and the first gear 9 on the other side of the distribution box 2 to rotate synchronously. A large transmission ratio is set between the first gear 9 and the second gear 12 and the servo motor 10 has a self-locking function, so that when the first gear 9 rotates a certain angle, the second gear 12 can rotate multiple times, thereby driving the cam 11 to hit the impact block 13 multiple times, thereby driving the screen box 5 to vibrate, thereby allowing the material in the screen box 5 to be quickly screened, thereby improving the working efficiency of the equipment; the material blocking block 30 is set to prevent unscreened material from falling near the openings at both ends of the screen box 5, thereby causing the magnetic ore to fall into the second discharge funnel 7 together with the impurities, causing resource waste and improving the recovery rate of the magnetic ore.

[0027] In this embodiment, both ends of the bottom of the screen box 5 are fixedly installed with a material blocking plate 28, and both ends of the screen box 5 are provided with a material blocking box 14. The two material blocking boxes 14 are fixedly installed on the adjacent side of the bottom frame 1, and the cleaning rollers 29 and the toothed discs 15 are rotatably installed on the inner and outer sides of the material blocking box 14, and a third gear 32 and a fourth gear 33 that are meshed are rotatably installed on one side of the material blocking box 14. The rotation center of one side of the third gear 32 is connected to one end of the cleaning roller 29 through a coupling, and one side of the fourth gear 33 is fixedly installed with the rotation center of the toothed disc 15 through a connecting shaft. The chain 16 is wound around the surfaces of the two toothed discs 15, and a counterweight block 17 is fixedly installed on one end of the chain 16, and a lifting block 27 is fixedly installed on the other end. A column 25 is fixedly installed on one side of the bottom frame 1, and a slide groove compatible with the lifting block 27 is opened on the side of the column 25 close to the chain 16. A reciprocating screw rod 26 is rotatably installed in the slide groove. One end of the reciprocating screw rod 26 passes through the outer surface of the lifting block 27 and is threadedly connected with it. The lifting block 27 is slidably installed in the slide groove. A second support frame 23 with a Z-shaped structure is fixedly installed on the top of the column 25. A meshing active bevel gear 22 and a driven bevel gear 24 are rotatably installed on one side of the second support frame 23. The center of one side of the active bevel gear 22 is fixedly installed with the rotation center of one side of the adjacent cam 11 through a connecting shaft, and the bottom rotation center of the driven bevel gear 24 is connected to the top of the reciprocating screw rod 26 through a coupling.

[0028] When in use, by setting the material blocking box 14 and cooperating with the material blocking plates 28 at the two ends of the bottom of the screening box 5, the scraper 20 can accurately drop the impurities into the second discharge funnel 7 when pushing the screening box 5, avoiding spilling outside the equipment and being unfavorable for recovery; a counterweight block 17 is set, and the lifting block 27 can pull the chain 16 to move in the direction of the counterweight block 17 during the upward movement of the reciprocating screw rod 26 thread drive. The two toothed discs 15 play a guiding role and keep the chain 16 in a taut state, so that it is convenient for the cleaning roller 29 to clean the residual impurities on the surface when it passes through the material blocking box 14. By opening an avoidance hole on the surface of the scraper 20, during the vibration process of the screen box 5, the adapter block 21 slides up and down in the avoidance hole, and at the same time does not affect the adapter block 21 driving the scraper 20 to move along the screen box 5, thereby improving the linkage consistency of the equipment.

[0029] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: when in use, the material is filled into the feed hopper 3, and the servo motor 10 drives the material distribution roller 18 to rotate in the material distribution box 2, and the material distribution cavity 19 carries an equal amount of material each time for separation, and then puts it into the screen box 5, and continues the rotation process. The cam 11 is driven to rotate through the first gear 9 and the second gear 12, and then the impact block 13 is struck to drive the screen box 5 to vibrate, and impurities such as ore sand are quickly screened out, and the driving bevel gear 22 and the driven bevel gear 24 are used for transmission to drive the reciprocating screw rod 26 to rotate. The lifting block 27 is then driven to slide down, and the lifting block 27 pulls the adapter block 21 through the chain 16, thereby driving the scraper 20 to slide along the screen box 5 toward one end of the opening, thereby cleaning the upper surface of the filter hole, and pushing impurities such as ore sand into the second discharge funnel 7. During the upward movement of the lifting block 27, the chain 16 is pulled to move to the other end through the counterweight block 17, thereby driving the scraper 20 to push the ore sand impurities into the second discharge funnel 7 on the other side of the equipment, so that the screen box 5 can be automatically cleaned under working conditions, avoiding shutdown for cleaning, thereby improving the continuous working capacity of the equipment, and thereby improving the working efficiency of magnetic ore separation.
