Description

Technical Field

[0001] The utility model relates to the technical field of duck feed production, in particular to a duck feed particle grading and screening cylinder. Background Art

[0002] The feed particles of different growth ages are of different sizes, and the feed particles often need to be screened and graded in duck feed production. Existing screening equipment mostly uses multiple sieve holes with different apertures for screening operations, such as a feed particle screening and grading device for duck feed production published in patent document CN213762830U and a screening device for duck feed published in CN220716741U. The aperture of this screen is fixed. For this reason, it is necessary to prepare multiple filter screens with different apertures in the screening process to meet daily production needs. Different filter screens often need to be replaced, which is inconvenient to use.

[0003] In view of the above problems, a duck feed particle grading screening cylinder is now provided, which can screen different particle diameters according to different requirements. It is flexible and convenient to use and can meet daily production needs. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a duck feed particle grading screening cylinder, which effectively solves the problem that the screening cylinder in the existing screening equipment cannot adjust the aperture and has limitations.

[0005] The technical solution is as follows: it comprises two coaxial annular plates, a plurality of movable plates evenly distributed in a circle are arranged between the two annular plates, first T-blocks are fixed at both ends of the movable plates, and first slide grooves corresponding to the first T-blocks are arranged on the end faces of the annular plates; the movable plates are in an isosceles trapezoidal shape, and a plurality of movable plates evenly distributed in a circle form a fence-like structure; there are two coaxial circular rings between the two annular plates, the two circular rings maintain a left-right symmetrical state, the two circular rings can move towards or away from each other at the same time, and the two circular rings approaching or moving away from each other can drive the plurality of movable plates to approach or move away from the axis of the annular plates; a plurality of second T-blocks corresponding to the movable plates are arranged on the inner side walls of the circular rings, and a plurality of second slide grooves corresponding to the second T-blocks are arranged on the movable plates.

[0006] Furthermore, a double-head hydraulic cylinder is arranged between the two arc-shaped plates, and the hydraulic cylinder is fixed on the movable plate. The hydraulic cylinder can drive the two circular rings to move toward or away from each other.

[0007] Furthermore, there are multiple double-ended screws evenly distributed around the circumference on the outside of the fence-like structure, with nuts screwed on both ends of the double-ended screws, and the nuts are fixed on a circular ring close to them; when the double-ended screws rotate, the two nuts on them can drive the two circular rings to move closer to or away from each other.

[0008] Furthermore, a small gear is fixed in the middle of the double-ended lead screw, and a gear ring is mounted on the outer side of the multiple double-ended lead screws. The rotation of the gear ring can drive the multiple double-ended lead screws to rotate simultaneously.

[0009] The utility model has an ingenious structure and can screen particles of different diameters according to different requirements. It is flexible and convenient to use and can meet daily production needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 4 It is given that the utility model includes two coaxial annular plates 1, a plurality of movable plates 2 uniformly distributed in a circle are arranged between the two annular plates 1, first T-blocks 3 are fixed at both ends of the movable plates 2, and first slide grooves 4 corresponding to the first T-blocks 3 are opened on the end faces of the annular plates 1; the movable plates 2 are isosceles trapezoidal, and a plurality of movable plates 2 uniformly distributed in a circle form a fence-like structure, and two coaxial circular rings 5 ​​are arranged between the two annular plates 1, and the two circular rings 5 ​​maintain a left-right symmetrical state, and the two circular rings 5 ​​can move toward or away from each other at the same time, and the two circular rings 5 ​​approaching or moving away from each other can drive the plurality of movable plates 2 to approach or move away from the axis of the annular plate 1; a plurality of second T-blocks 6 corresponding to the movable plates 2 are arranged on the inner side wall of the circular ring 5, and a plurality of second slide grooves 7 corresponding to the second T-blocks 6 are arranged on the movable plates 2.

[0016] In order to achieve the two circular rings 5 ​​approaching or moving away from each other, the outside of the fence-like structure is provided with a plurality of double-headed screws 8 evenly distributed in a circle, and nuts 9 are screwed on both ends of the double-headed screws 8, and the nuts 9 are fixed on the circular rings 5 ​​close to it; when the double-headed screw 8 rotates, it can drive the two circular rings 5 ​​to approach or move away from each other through the two nuts 9 thereon.

[0017] In order to realize synchronous rotation of multiple double-ended lead screws 8, a pinion 10 is fixed in the middle of the double-ended lead screw 8, and a gear ring 11 is mounted on the outer side of the multiple double-ended lead screws 8. The rotation of the gear ring 11 can drive the multiple double-ended lead screws 8 to rotate simultaneously.

[0018] In order to achieve the two rings 5 ​​to move closer to or farther away from each other, a double-headed hydraulic cylinder is provided between the two arc-shaped plates. The hydraulic cylinder is fixed on the movable plate 2 and can drive the two rings 5 ​​to move toward or away from each other.

[0019] It is worth noting that when this device is in use, it needs to be used in conjunction with a screening machine. The screening machine provides rotational force to this structure, and then the material enters from the center of one of the annular plates 1, and small particles fall through the gaps between multiple arc plates. Large particles are retained in the fence structure. After a period of time, the retained large particles are poured out uniformly for secondary processing.

[0020] When in use, the material enters the screening cylinder cavity from one end of the device, and small particles fall through the gap between two adjacent movable plates 2, while large particles are retained in the fence structure composed of multiple movable plates 2. After a period of time, the large particles are poured out; when the diameter of the screening particles needs to be adjusted, the gear ring 11 is screwed, and the gear ring 11 drives multiple double-headed screws 8 to rotate simultaneously through multiple pinions 10, so that the two rings 5 ​​are close to or away from each other, so that the gap between adjacent movable plates 2 will be expanded or reduced, thereby achieving the purpose of adjusting the grade of screening particles.

[0021] The utility model has an ingenious structure and can screen particles of different diameters according to different requirements. It is flexible and convenient to use and can meet daily production needs.
