Description
Technical field
This utility model relates to a kind of novel fodder extrusion cavities and a kind of ring mould for feedstuff extrusion.
Background technology
It is the highest that its technical bottleneck that current market is deeply concerned is that the manufacture of complete feed (i.e. feedstuff) exists utilization rate in the utilization of low cost grain (Fructus Hordei Vulgaris, Sorghum vulgare Pers., Maninot esculenta crantz., DDGS etc.), the easy efflorescence to grain density up to standard cannot be suppressed, its quality, nutrition, edible safety and environmental protection are all unable to reach satisfied requirement, it is difficult to come into the market circulation.
The pass that existing feed granules shapes has straight pass, and it manufactures convenient, but shortcoming is also apparent from.Straight pass generally comprises the poroid guide district of loudspeaker and straight hole, quenched after material by guide district (bellmouth orifice), through being once squeezed in straight hole internal shaping.The length of straight hole and bore dia are than referred to as compression ratio, axial force retroaction pressure initiation extruding to guide district to guide district root and pressure roller of the formation that mainly rubbed feedstuff by straight hole inwall, and are compacted further in straight hole leading portion.When arriving straight hole back segment, feedstuff has been compacted, and surface forms the bright layer of hardening, is gradually reduced to frictional force during straight hole back segment.When material positive pressure is more than frictional force, it is extruded formation granule by the feedstuff of straight hole.To this end, straight pass nib is the extruding density that can't resolve granule as strengthened compression ratio.
Utility model content
The purpose of this utility model is to provide the shape hole of a kind of extruding density that can improve feed granules.
For solving the problems referred to above, this utility model provides a kind of novel fodder extrusion cavities, including the elongated nib for rotary structure, the two ends of described nib are provided with charging aperture and discharging opening, it is characterised in that described nib also includes the first shape and the second shape hole being connected, described charging aperture is arranged on described first shape hole, described discharging opening is arranged on described second shape hole, and described second shape hole is cylindricality, and described first shape hole is taper.
As further improvement of the utility model, described first shape hole includes the first branch being provided with described charging aperture, and the second branch connected with described second shape hole, and described first branch and the second branch are taper.
As further improvement of the utility model, the value of the cone angle of described first branch is α, wherein, and 30 °≤α≤55 °.
As further improvement of the utility model, the value of the cone angle of described second branch is β, wherein 0.5 °≤β≤2.5 °.
As further improvement of the utility model, value α=35 ° of the cone angle of the first branch.
Additionally, with this utility model, there is monistic utility model to create, a kind of ring mould for feedstuff extrusion, including ring-type mould body, described mould body is provided with the through hole of at least one its inner and outer wall through, it is characterized in that, described through hole is the nib in described novel fodder extrusion cavities, and described charging aperture and described discharging opening in described nib are separately positioned on the inner and outer wall of described mould body.
The beneficial effects of the utility model are, use the hole shape structure in this utility model, it is possible to feedstuff is pressed into grain density up to standard, solves produced problem in prior art.

Detailed description of the invention
Below detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, this utility model includes the elongated nib 2 for rotary structure, the two ends of described nib 2 are provided with charging aperture 4 and discharging opening 6, it is characterized in that, described nib 2 also includes the first shape and the second shape hole 10 being connected, and described charging aperture 4 is arranged on described first shape hole 8, and described discharging opening 6 is arranged on described second shape hole 10, described second shape hole 10 is cylindricality, and described first shape hole 8 is taper.
As further improvement of the utility model, described first shape hole 8 includes that the first branch 12 being provided with described charging aperture 4, and the second branch 14 connected with described second shape hole 10, described first branch 12 and the second branch 14 are taper.
As further improvement of the utility model, the value of the cone angle of described first branch 12 is α, wherein, and 30 °≤α≤55 °.
As further improvement of the utility model, the value of the cone angle of described second branch 14 is β, wherein 0.5 °≤β≤2.5 °.
As further improvement of the utility model, value α=35 ° of the cone angle of the first branch 12.
Additionally, with this utility model, there is monistic utility model to create, a kind of ring mould for feedstuff extrusion, including ring-type mould body 16, described mould body 16 is provided with the through hole of at least one its inner and outer wall through, it is characterized in that, described through hole is the nib 2 in described novel fodder extrusion cavities, and described charging aperture 4 and described discharging opening 6 in described nib 2 are separately positioned on the inner and outer wall of described mould body 16.
Concrete principle of the present utility model is as follows:
(1) this utility model uses the first shape hole 8 of taper, after pellet enters the first shape hole 8, simultaneously by power that the first shape hole 8 inwall is radial and axial, the extruding to feedstuff can be strengthened, be conducive to the compression of feedstuff, meanwhile, this power can guarantee that the extruding to feedstuff will not be interrupted continuously, and all parts of feedstuff are constantly in the state of operating at full capacity；
(2) this utility model also sets up column and the second shape hole 10 connected with the first shape hole 8, it is intended that after surface forms the decline of bright layer frictional force, can keep providing the extruding force being gradually reduced, by particles cured steady shape.After feed granules enters the second steady shape in shape hole 10, it is possible to increase feed granules quality, extend the service life of ring mould simultaneously.
(3) the manufacture key point of this technology is the frictional force that the first shape hole 8 is gradually increased, and facilitates the balance between radial compression power and axial compression power simultaneously.
Above example is only this utility model a kind of embodiment therein, and it describes more concrete and detailed, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, for the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into protection domain of the present utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
