Description

Technical Field

[0001] The utility model relates to the technical field of processing of fish and shrimp feed, in particular to a screening mechanism for processing fish and shrimp feed. Background Art

[0002] In the processing of existing fish and shrimp feed, there are the following disadvantages. In the existing feed crushing, there is an incomplete crushing phenomenon, resulting in uneven crushing of fish and shrimp feed particles. At this time, it is necessary to screen out large particles and crush them again, and adjust the particle size after crushing according to different fish species. In the existing technology, the method of changing the filter screen is mostly used to screen different particles. The Chinese patent document CN218308215U discloses a device for processing fish and shrimp feed for aquaculture. Such a scheme requires changing the filter screen to achieve different feed with different particle size requirements, which is troublesome to operate and not convenient to adjust. In addition, if such a filter screen is partially damaged or the mesh is broken, only the whole filter screen can be replaced, and the resource utilization rate is greatly reduced.

[0003] Now a screening mechanism for processing fish and shrimp feed is provided, which can conveniently adjust the size of filtered particles, is convenient to operate, can quickly repair the locally damaged area, greatly improves the resource utilization rate, and is beneficial to reducing production costs. Summary of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a screening mechanism for processing fish and shrimp feed, which effectively solves the problems that the existing filter screen cannot adjust the size of filtered particles, is not convenient to repair when the filter screen is partially damaged, and the utilization rate of the filter screen needs to be improved.

[0005] The technical solution it adopts is that it includes a rectangular frame. The rectangular frame is formed by four long rods connected end to end to form a parallelogram mechanism, and the ends of adjacent long rods are hinged together; a plurality of cross chords are connected between the left and right long rods in the rectangular frame, and a plurality of longitudinal chords are connected between the front and rear long rods in the rectangular frame. A plurality of cross chords and a plurality of longitudinal chords intersect with each other to form a uniform grid; there is a double-headed screw at the right front end of the rectangular frame. Nuts are screwed at both ends of the double-headed screw. One of the nuts is hinged to the front end of the right long rod, and the other nut is hinged to the right end of the front long rod; screwing the double-headed screw can control the angle between the cross chord and the longitudinal chord, thereby realizing the adjustment of the grid size.

[0006] Further, there is a vertical cylinder on the upper side of the rectangular frame. There is an annular plate under the cylinder. The annular plate and the lower end of the cylinder are fixed together by a bolt structure, and the annular plate and the cylinder can clamp the cross chord and the longitudinal chord.

[0007] Further, a rubber ring gasket is arranged on the upper end surface of the annular plate.

[0008] Furthermore, a plurality of threaded holes are formed on the outer side of the long rod, and screws are screwed into the threaded holes. The ends of the cross chords and longitudinal chords are fixed to the corresponding screws, and the tension of the cross chords or longitudinal chords can be adjusted by screwing the screws.

[0009] The utility model has a clever structure, can conveniently adjust the size of the filtering particles, is easy to operate, can quickly repair the locally damaged area, greatly improves the resource utilization rate, and is beneficial to reducing the production cost.

[0014] The following further describes in detail the specific embodiments of the utility model with reference to the drawings.

[0015] As shown by Figures 1 to 4 , the utility model includes a rectangular frame, which is formed by connecting four long rods 1 end to end to form a parallelogram mechanism, and the ends of adjacent long rods 1 are hinged together; a plurality of cross chords are connected between the left and right long rods 1 in the rectangular frame, and a plurality of longitudinal chords are connected between the front and rear long rods 1 in the rectangular frame. The plurality of cross chords and the plurality of longitudinal chords intersect with each other to form a uniform grid 2; there is a double-headed screw 3 on the right front end of the rectangular frame, and nuts 4 are screwed at both ends of the double-headed screw 3. One of the nuts 4 is hinged to the front end of the right long rod 1, and the other nut 4 is hinged to the right end of the front long rod 1; by screwing the double-headed screw 3, the included angle between the cross chords and the longitudinal chords can be controlled, so as to adjust the size of the grid 2.

[0016] In order to prevent feed particles from falling from the side of the long rod 1, there is a vertical cylinder 5 on the upper side of the rectangular frame, and there is an annular plate 6 under the cylinder 5. The annular plate 6 and the lower end of the cylinder 5 are fixed together by a bolt structure, and the cross chords and longitudinal chords can be clamped between the annular plate 6 and the cylinder 5.

[0017] In order to prevent the cross chords and longitudinal chords from shifting, a rubber ring gasket is provided on the upper end surface of the annular plate 6.

[0018] To facilitate the replacement of the horizontal strings or vertical strings, a plurality of threaded holes are provided on the outer side of the long rod 1, and screws 7 are screwed into the threaded holes. The ends of the horizontal strings and vertical strings are fixed to the corresponding screws 7, and by screwing the screws 7, the tension of the horizontal strings or vertical strings can be adjusted.

[0019] It should be noted that the annular plate 6 and the lower end of the cylinder 5 press and fix the horizontal strings and vertical strings, so that the size and shape of the formed grid 2 do not change, and feed leakage is also prevented; the present invention only provides a sieve structure, and in specific use, it is used in cooperation with a vibrating machine and the like, and the effect is better.

[0020] During use, the crushed feed is poured into the cylinder 5, and then the rectangular frame is shaken to keep the uncrushed large particles in the cylinder 5, and the uncrushed large particles are placed in a crusher for secondary crushing; when it is necessary to adjust the size of the sieved particles, first remove the annular plate 6, and then pull out the cylinder 5. At this time, screw the double-headed bolt, so that the rectangular frame deforms, and further the distance between adjacent horizontal strings and the distance between adjacent vertical strings both change, making the grid 2 larger or smaller. Then, clamp the horizontal strings and vertical strings again with the cylinder 5 and the annular plate 6. At this time, the adjustment is completed and normal work can be carried out.

[0021] The utility model has a clever structure, can conveniently adjust the size of the filtered particles, is easy to operate, can quickly repair the locally damaged area, greatly improves the resource utilization rate, and is beneficial to reducing the production cost.
