[0028] A screening assembly is slidably arranged inside the screening frame and located between the screening frame and the conveyor belt 1; the screening assembly includes:

[0029] The height limiting block 3, the guide block 4 and the blocking block 5 are all slidably connected to the screening frame, the width of the height limiting block 3 is equal to the width of the conveyor belt 1, the width of the guide block 4 and the blocking block 5 is less than or equal to half the width of the conveyor belt 1, the distance between the height limiting block 3 and the conveyor belt 1 is greater than or equal to the height of qualified ferrite products, the distance between the guide block 4 and the conveyor belt 1 is less than the height of qualified ferrite products, the distance between the blocking block 5 and the conveyor belt 1 is less than the distance between the guide block 4 and the conveyor belt 1, and the distance between the blocking block 5 and the conveyor belt 1 is greater than zero; the height of the height limiting block 3 is greater than or equal to the height of qualified ferrite products, thereby blocking thicker ferrite from entering the grinding line; the height of the guide block 4 is less than or equal to the height of qualified ferrite products, thereby blocking ferrite within a certain size range; the distance between the blocking block 5 and the conveyor belt 1 is shorter, which is used to block some thinner ferrites and avoid direct contact between the blocking block 5 and the conveyor belt 1, causing the conveyor belt 1 to be stuck;

[0030] The cross-sectional views of the height limiting block 3, the guide block 4 and the blocking block 5 are all right triangles, and one side of the height limiting block 3, the guide block 4 and the blocking block 5 are located on the same vertical plane, wherein the right-angled sides of the height limiting block 3 and the guide block 4 are in opposite directions to the right-angled sides of the blocking block 5, and the hypotenuses of the height limiting block 3 and the blocking block 5 are facing the recycling box 2; the ferrite blocked by the height limiting block 3 will slide into the recycling box 2 under the action of the conveyor belt 1 and the hypotenuse, and the width of the guide block 4 is less than half of the conveyor belt 1, and then the guide block 4 will guide the ferrite to slide to the unobstructed position of the conveyor belt 1, and the thinner ferrite will slide to the recycling box 2 on the other side under the action of the blocking block 5;

[0031] In actual application, the ferrite qualified product screening equipment is provided with a height limit block 3, a guide block 4 and a blocking block 5 at different distances from the conveyor belt 1. The distance between the height limit block 3 and the guide block 4 and the conveyor belt 1 is limited by the height of the qualified ferrite products, thereby guiding the higher ferrite into the recycling box 2, and guiding the ferrite that reaches the position of the guide block 4 to be transmitted on the unobstructed surface of the conveyor belt 1, and the thinner ferrite will enter the recycling box 2 on the other side under the action of the blocking block 5, thereby ensuring that the ferrite that meets the height requirement will continue to move under the action of the conveyor belt 1, and ensuring that the ferrite entering the grinding line will not get stuck in the grinder;

[0032] In some specific embodiments, the blocking block 5 is internally slidably connected to a plurality of telescopic rods 61 and a plurality of connecting rods 62, the middle portion of the telescopic rod 61 is rotatably connected to a transfer rod 63, the other end of the transfer rod 63 is fixedly connected to the middle portion of the connecting rod 62, and one end of the telescopic rod 61 and the connecting rod 62 close to the recycling box 2 are both rotatably connected to a fixed rod 64, and the fixed rod 64 is fixedly connected to the blocking block 5; a synchronously rotating synchronization component is provided between the telescopic rod 61 and the connecting rod 62;

[0033] In a further embodiment, the synchronization assembly includes a synchronization rod 71, which is rotatably connected to the telescopic rod 61 and one end of the connecting rod 62. The surface of the synchronization rod 71 is rotatably connected to a synchronization cone wheel 72. The end of the telescopic rod 61 close to the connecting rod 62 and the end of the connecting rod 62 close to the telescopic rod 61 are fixedly connected to a drive cone wheel 73, and the drive cone wheel 73 is meshed with the synchronization cone wheel 72; the rotation of the telescopic rod 61 on one side will cause the drive cone wheel 73 on that side to rotate relative to the synchronization rod 71, thereby causing the synchronization cone wheel 72 to rotate, driving the drive cone wheel 73 at one end of the connecting rod 62 to rotate, and the two drive cone wheels 73 rotate in opposite directions, thereby causing the distance between the connecting rod 62 and the telescopic rod 61 to increase;

[0034] In a further embodiment, the surface of the blocking block 5 is rotatably connected to a driving block 81, and a driving groove 82 is opened on the surface of the driving block 81, and the driving groove 82 is adapted to the transfer rod 63; a pressing column 83 is slidably connected to the inside of the driving block 81, and a pressing spring 84 is fixedly connected between the pressing column 83 and the blocking block 5; a pressing shaft 85 is fixedly connected to the inside of the driving block 81, and a spiral groove 86 is opened on the surface of the pressing column 83, and the pressing shaft 85 is adapted to the spiral groove 86;

[0035] The working principle of the present utility model is as follows: the conveyor belt 1 is started, and a ferrite is placed on the side of the conveyor belt 1 surface that can contact the guide block 4. The ferrite first contacts the height limit block 3, and the higher ferrite moves toward the recycling box 2. The ferrite passing through the height limit block 3 moves backward and contacts the guide block 4. The ferrite touching the guide block 4 slides to the other side of the conveyor belt 1 and is transmitted backward. The ferrite passing through the guide block 4 moves backward and contacts the blocking block 5, pushing the pressing column 83 into the inside of the blocking block 5. The sliding of the pressing column 83 drives the driving block 81 to rotate, and the rotation of the driving block 81 drives a certain transfer rod 63 to slide. The sliding of the transfer rod 63 causes the angle between the single telescopic rod 61 and the connecting rod 62 to decrease, and then under the action of the synchronization component, all the telescopic rods 61 and the connecting rod 62 rotate and extend to a position outside the blocking block 5. The blocking block 5 guides the ferrite to slide to the recycling box 2 on the other side.
