DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0022] As Figure 1 shown, a cooling type creep feed screening device includes a screening mechanism 1 and a cooling mechanism 2. The screening mechanism 1 includes a primary screening box 11 and a secondary screening box 12. An inlet 3 is provided on the upper surface of the primary screening box 11, and a first discharge port 4 is provided on the side surface of the primary screening box 11. The first discharge port 4 is in a circular cylindrical structure, and the end opening of the first discharge port 4 penetrates through the outer surface of the screening device, and the other end opening communicates with the inner surface of the screening device.

[0023] As Figure 2 shown, a pusher 5 and a first screening plate 6 are provided inside the primary screening box 11, and first through holes are uniformly distributed on the first screening plate 6. The shaft body of the pusher 5 is a hollow cylindrical shaft body. One end of the cavity in the middle of the pusher 5 communicates with the water inlet pipe 23 of the cooling mechanism 2, and the other end communicates with the water outlet pipe 22 of the cooling mechanism 2. The cooling mechanism 2 includes a water cooling box 21, a water outlet pipe 22 and a water inlet pipe 23, and both the water outlet pipe 22 and the water inlet pipe 23 communicate with the side surface of the screening mechanism 1.

[0024] Second discharge ports 7 and third discharge ports 8 are provided on the opposite side surfaces of the secondary screening box 12. A second screening plate 9 and a third screening plate 10 are provided inside the secondary screening box 12. The second discharge port 7 corresponds to the outlet of the second screening plate 9, and the third discharge port 8 corresponds to the outlet of the third screening plate 10. The second screening plate 9 is located above the third screening plate 10, and the inclined structures of the second screening plate 9 and the third screening plate 10 are arranged in opposite directions. Sieve holes are uniformly distributed in the middle and lower parts of the second screening plate 9 and the third screening plate 10. The creep feed will be screened after falling and sliding for a certain distance, preventing blockage caused by a large amount of creep feed falling concentratedly. And the inclined structure extends the sliding path of the creep feed, which is convenient for screening. A collection bucket inserted into the inner side of the secondary screening box 12 is provided below the third screening plate 10 for collecting the lower-layer screened materials.

[0025] A hollow cavity is provided inside the box wall of the screening mechanism 1. The water outlet pipe 22 of the cooling mechanism 2 communicates with the upper part of the screening mechanism 1, and its water inlet pipe 23 communicates with the bottom of the screening mechanism 1. The water of the cooling mechanism passes through the upper part of the screening mechanism, flows through the inside, and then flows out from the lower part, so that the whole screening mechanism 1 is cooled.

[0026] When the starter feed particles enter the first-stage screening machine, the first-stage screening machine maintains a relatively low temperature under the action of the water-cooling box 21. The starter feed particles pass through the first screening plate 6 under the push of the pusher 5. The starter feed particles that do not meet the specifications of the starter feed pass through the first discharge port 4 for easy crushing and feeding. The starter feed particles that meet the regulations pass through the second screening plate 9, and the starter feed particles with a diameter of 2.0 - 3.0 mm are screened out. The third screening plate 10 screens out the starter feed particles with a diameter of 1.0 mm. The starter feed particles with a diameter of 1.0 mm are more convenient for piglets to absorb, and the starter feed particles with a diameter of 2.0 - 3.0 mm are convenient for young pigs to absorb.

[0027] In summary, the cooling type starter feed screening device of the present utility model with the above structure realizes the full cooling of the starter feed; and realizes the fine screening of the starter feed particles through the second screening plate and the third screening plate.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
