Description

Technical Field

[0001] This utility model relates to the field of feed machinery technology, and in particular to an extrusion die for a ring die pellet mill. Background Technology

[0002] In feed production lines, ring die pellet mills are commonly used feed equipment. The ring die is the extrusion die of the pellet mill. The ring die has circumferentially distributed circular holes. During operation, the crushed material is fed into the ring die and squeezed into round pellets through the circular holes on the ring die. Then, it is cut into cylindrical pellets of a certain length by the cutter outside the ring die, forming livestock feed for use in the breeding industry.

[0003] However, with the continuous development of aquaculture, the variety of aquatic organisms being farmed is increasing, no longer limited to ponds and inland lakes. Marine aquaculture is also becoming more and more developed. For example, abalone, which was originally harvested from the seabed, is now being farmed on a large scale. The feed used in aquaculture was originally produced into round pellets using a ring die pellet mill. Because abalone crawl and feed slowly, and because the pelleted feed is easily washed away by seawater, this resulted in a significant waste of feed and increased farming costs. Summary of the Invention

[0004] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a ring die pellet mill extrusion die that can reduce feed waste and lower breeding costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a ring die pellet mill extrusion die, including a ring die body, wherein a number of rows of flat hole groups are evenly distributed around the ring die body, and at least four flat holes are arranged in the axial direction of the ring die body. The center distance between adjacent flat holes is greater than the length of the flat hole by 2 to 15 mm, and the distance between adjacent flat hole groups is greater than the width of the flat hole by 2 to 15 mm. The inner edge of the flat hole located at the inner circular end of the ring die body has a feeding flared mouth.

[0006] Furthermore, the centers of the flat holes in adjacent flat hole groups are offset by 2 to 20 mm.

[0007] Specifically, the angle between the feed flare and the length of the flat hole is 5 to 60°, and the angle between the feed flare and the width of the flat hole is 5 to 60°.

[0008] Preferably, the angle between the feed flare and the length of the flat hole is equal to the angle between the feed flare and the width of the flat hole.

[0009] The beneficial effects of this invention are: by evenly distributing flat holes along the circumference of the annular mold, this invention can produce flat feed. Since this flat feed is not easily moved by the water flow when it is put into the bottom of the aquaculture farm, it can provide better feeding convenience for aquaculture organisms with slow movement speed and long feeding time, reduce feed waste, and lower aquaculture costs.

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] like Figures 1-4 The extrusion die of a ring die pellet mill shown includes a ring die body 1, with several rows of flat hole groups 2 evenly distributed along the circumference of the ring die body 1. Each row of flat hole groups 2 has four flat holes 3 arranged along the axial direction of the ring die body 1. A feed flared mouth 4 is opened on the inner edge of the flat hole 3 located at the inner circular end of the ring die body 1.

[0018] In each row of flat hole groups 2, the center distance between adjacent flat holes 3 is A, and the length of A is 2 to 15 mm longer than the length of the flat hole 3 itself. The spacing between adjacent flat hole groups 2 is B, and B should be 2 to 15 mm wider than the width of the flat hole 3 itself. The centers of the flat holes 3 between adjacent flat hole groups 2 are offset by a distance C, and the size of C is 2 to 20 mm.

[0019] The included angle α of the feed flare 4 in the length direction of the flat hole 3 is 5 to 60°, and the included angle β of the feed flare 4 in the width direction of the flat hole 3 is 5 to 60°.

[0020] In practical use, it is preferable that the included angle α of the feed flare 4 in the length direction of the flat hole 3 is equal to the included angle β of the feed flare 4 in the width direction of the flat hole 3.

[0021] When the extrusion die with this structure is used for feed production, after the material is extruded from the flat hole 3, it can be cut by a cutter to produce flat feed. This flat feed is not easily moved by the seawater when it is put into the seabed of the marine aquaculture farm, which can provide better feeding convenience for aquaculture organisms with slow movement speed and long feeding time, and reduce feed waste. In addition, the flat holes 3 are evenly distributed in the width and circumferential directions of the annular die 1, and the spacing between each row of flat hole groups 2 can improve the uniformity of output, product quality and output. The feed flare 4 is set at the edge of the feed end of the flat hole 3, which can further improve product quality and output.

[0022] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
