Abstract

Disclosed is a granulator. A ring die is sleeved on two press rolls, center lines of the press rolls are superposed on the diameter of the ring die, fodder is placed between the ring die and the press rolls, cutters are arranged on the outer side of the ring die and the outer die of an extruding portion of each press roll, a plurality of discharge ports are arranged on the periphery of the ring die, some of the discharge ports are round, and others of the discharge ports are square. The discharge ports include the round discharge ports and the square discharge ports, so that produced fodder granules are different in shape while larger voids are reserved among the granules.

Description

A kind of granulator

Technical field

The utility model relates to the technical field of plant equipment, relates in particular to a kind of granulator.

Background technology

The feed granules that traditional granulator is produced is columniform, and the space is little between the particle.Because the breeding cycle of sow is very long, length can reach 6-8, and is high to the nutritional requirement of feed, and the feed crude fiber content that this granulator is made is low, can cause wall attenuation of sow intestines even enterobrosis, and situation is very serious.

Summary of the invention

The technical problem that the utility model will solve provides the bigger granulator in space between a kind of output feed granules shape difference, the particle.

The technical scheme that addresses the above problem is: this granulator; The ring die sleeve is on two pressure rollers, and the center line of two pressure rollers overlaps with the diameter of ring mould, and feed is placed between ring mould and the pressure roller; The outside of ring mould and pressure roller crimping section is provided with cutting knife; The circumference of ring mould is provided with a plurality of discharging openings, and the some of them discharging opening is circular, and other discharging openings are square.

Because discharging opening is square except also having of circle, so output feed granules shape is different, the space is bigger between the particle.

Description of drawings

Fig. 1 is the structural representation according to the granulator of the utility model;

Fig. 2 is the partial enlarged drawing of the side view of Fig. 1.

Specific embodiments

As shown in Figure 1, this granulator, ring mould 1 is enclosed within on two pressure rollers 2; The center line of two pressure rollers 2 overlaps with the diameter of ring mould 1; Feed 3 is placed between ring mould 1 and the pressure roller 2, and the outside of ring mould and pressure roller crimping section is provided with cutting knife 4, and the circumference of ring mould is provided with a plurality of discharging openings 5; The some of them discharging opening is circular, and other discharging openings are square.Its operation principle is: granulator drives the ring mould and rotates, and feed gets between ring mould and the pressure roller, goes out from the ring mold pressing through the extruding feed, and the profile of feed is by the shape decision of ring mould discharging opening.The circular columniform feed granules of discharging opening output, the feed granules of square discharging opening output cuboid.

Further, the discharging opening of circle and square discharging opening are arranged alternately.

Because it is round that original feed is, the space is little each other, does not give sow intestines wall to stimulate; And the utility model increases the wriggling and the friction of sow intestines wall through the extruding between two kinds of difformity feeds, increases elasticity.

The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs to the protection domain of the utility model technical scheme to any simple modification, equivalent variations and modification that above embodiment did.

Claims (2)

1. granulator; Ring mould (1) is enclosed within on two pressure rollers (2), and the center line of two pressure rollers (2) overlaps with the diameter of ring mould (1), and feed (3) is placed between ring mould and the pressure roller; The outside of ring mould and pressure roller crimping section is provided with cutting knife (4); The circumference of ring mould is provided with a plurality of discharging openings (5), and the some of them discharging opening is circular, it is characterized in that: other discharging openings are square.

2. granulator according to claim 1 is characterized in that: circular discharging opening and square discharging opening are arranged alternately.
