By providing the vibration assembly, the first support plate 3 and the second support plate 7 slide in the chutes 2, and then the screening and collection of the premixed powder are completed.

[0024] The vibration assembly includes a concave-convex ring 8 and a power unit; the concave-convex ring 8 is rotatably connected to the inner circumferential wall of the housing 1; a pair of connecting rods 9 are fixedly connected to the bottom end of the collection box 6; a conical block 10 is fixedly connected to the bottom end of each of the pair of connecting rods 9; a pair of the conical blocks 10 are slidably connected to the top end of the concave-convex ring 8; an elastic block 11 is fixedly connected to the bottom end of each of a set of the chutes 2. During operation, the concave-convex ring 8 is driven to rotate by the power unit, so that the concave-convex ring 8 squeezes the collection box 6 through the conical block 10 and the connecting rod 9. After the collection box 6 moves upward a certain distance, the collection box 6 will fall downward because the concave-convex ring 8 and the conical block 10 are not in contact. The second support plates 7 on both sides of the collection box 6 will drive the collection box 6 to rebound due to the elastic block 11. By circulating in this way, a vibration effect is generated, and the screening of the premixed powder by the screening frame 4 is completed.

[0025] The power unit includes a motor 12; the motor 12 is fixedly connected inside the housing 1 through a cross plate 13; a rotating rod 14 is provided at the output end of the motor 12; one end of the rotating rod 14 penetrates to the top of the screening frame 4; a rotating ring 15 is fixedly connected to the outer circumferential wall of the rotating rod 14; a pair of connecting plates 16 are fixedly connected to the outer circumferential wall of the rotating ring 15; one side of each of the pair of connecting plates 16 is fixedly connected to the inner circumferential wall of the concave-convex ring 8; both the screening frame 4 and the collection frame 6 are slidably connected to the rotating rod 14. During operation, the motor 12 is fixed by arranging the cross plate 13 inside the housing 1, the rotating rod 14 is arranged at the output end of the motor 12, the rotating rod 14 penetrates to the top of the screening frame 4, so that the screening frame 4 and the collection frame 6 are slidably connected to the rotating rod 14. By fixedly connecting the rotating ring 15 to the rotating rod 14, a pair of connecting plates 16 are fixedly connected to the rotating ring 15, and the connecting plates 16 are fixedly connected to the concave-convex ring 8, the rotating rod 14 drives the concave-convex ring 8 to rotate, thereby driving the screening frame 4 and the collection frame 6 to move upward.

[0027] A runner 20 is fixedly connected to the top end of the rotating rod 14; a group of conical plates 21 are fixedly connected to the outer circumferential wall of the runner 20. During operation, the runner 20 is fixedly connected to the top end of the rotating rod 14, and a group of conical plates 21 are arranged outside the runner 20. When the equipment is working, the rotating rod 14 drives the runner 20 and the conical plates 21 to rotate. When the vibration component drives the collection frame 6 and the screening frame 4 to move upward, the conical plates 21 can gradually fit with the screening plate, scrape the screening plate once, break some premixed powder particles that may be stuck in the screening frame 4 or remove them from the holes in the screening frame 4, preventing the screening frame 4 from being blocked.

[0028] A rubber pad is provided at the bottom end of the support leg 5. During operation, by arranging the rubber pad at the bottom end of the support leg 5, when the equipment screens the premixed powder, it can buffer the equipment, reduce the noise during the operation of the equipment, protect the bottom of the equipment and extend the service life of the equipment.

[0029] Working principle: By setting the housing 1, a pair of sliding grooves 2 are opened inside the housing 1. The first support plate 3 and the second support plate 7 are arranged in the sliding grooves 2 to support the screening frame 4 and the collection frame 6 respectively. By setting the vibration assembly, the first support plate 3 and the second support plate 7 slide in the sliding grooves 2, and then the screening and collection of the premixed powder are completed. The power unit drives the concave-convex ring 8 to rotate, and the concave-convex ring 8 squeezes the collection frame 6 through the conical block 10 and the connecting rod 9. After the collection frame 6 moves upward a certain distance, the collection frame 6 will fall downward because the concave-convex ring 8 and the conical block 10 are not in contact. The second support plates 7 on both sides of the collection frame 6 will drive the collection frame 6 to rebound due to the elastic blocks 11. By cycling in this way, a vibration effect is generated, and the screening frame 4 completes the screening of the premixed powder. The motor 12 is fixed by setting a cross plate 13 inside the housing 1. The output end of the motor 12 is provided with a rotating rod 14.

A rotating ring 15 is fixedly connected to the rotating rod 14, a pair of connecting plates 16 are fixedly connected to the rotating ring 15, and the connecting plates 16 are fixedly connected to the concave-convex ring 8, so that the rotating rod 14 drives the concave-convex ring 8 to rotate, and then the screening frame 4 and the collection frame 6 move upward. By setting a conical ring 17 inside the collection frame 6, a pair of through grooves 18 are opened on the collection frame 6 and penetrate through the housing 1. After the premixed powder is screened into the collection frame 6, due to the vibration assembly, the premixed powder gradually vibrates outwards from the through grooves 18. The staff can prepare the collection items in advance to collect the premixed powder. By fixedly connecting a runner 20 to the top end of the rotating rod 14 and arranging a set of conical plates 21 outside the runner 20, the runner 20 and the conical plates 21 can be driven to rotate by the rotating rod 14 when the equipment is working. When the vibration assembly drives the collection frame 6 and the screening frame 4 to move upward, the conical plates 21 can gradually fit with the screening plate, and can scrape the screening plate once, crushing some premixed powder particles that may be stuck in the screening frame 4 or removing them from the holes in the screening frame 4 to prevent the screening frame 4 from being blocked. By setting rubber pads at the bottom ends of the support legs 5, when the equipment screens the premixed powder, it can buffer the equipment, reduce the noise during equipment operation, protect the bottom of the equipment and extend the service life of the equipment.
