The first motor 334 is placed below the table board 1, which can reduce the volume occupied by the first motor 334 on the side of the extrusion cylinder 3.

The other end of the extrusion cylinder 3 is connected with a stirring cavity 4, and powdery feed and water can be put into the stirring cavity 4. After being stirred by a stirring assembly 41, the feed enters the extrusion cylinder 3. The auger blades 33 are in a spiral shape, and when the auger blades 33 rotate in the extrusion cylinder 3, the feed in the extrusion cylinder 3 is pushed to a leak hole plate 31 arranged at one end of the extrusion cylinder 3, and the feed is extruded and comes out of the leak holes of the leak hole plate 31. A support rod 5 is arranged on one side of the extrusion cylinder 3, the support rod 5 is provided with a second motor 51, the second motor 51 is transmissionally connected with a cutting rod 52, and the second motor 51 drives the cutting rod 52 to reciprocally scan on the end face of the leak hole plate 31, so that the extruded feed coming out of the leak holes is cut into particles by the cutting rod 52.

Further, a hot air machine 6 is arranged on the other side of the extrusion cylinder 3, and the air outlet of the hot air machine 6 faces the leak hole plate 31, so as to heat the feed coming out of the leak hole plate 31, which is helpful for the rapid formation of the feed particles.

Further, during the process of feed extrusion and granulation, the size of the feed particles is not uniform. The lower end of the leak hole plate 31 is provided with an inclined first sieve plate 71 and a second sieve plate 72, the second sieve plate 72 is arranged below the first sieve plate 71, the lower end of the second sieve plate 72 is provided with a third hopper 721, the leak holes of the first sieve plate 71 are larger than those of the second sieve plate 72, the first sieve plate 71 first screens the larger blocks, the screened feed particles fall on the second sieve plate 72, the second sieve plate 72 screens the small feed particles, the small feed falls below the second sieve plate 72, and finally the feed particles with uniform size fall into the third hopper 721 through the inclined second sieve plate 72 for collection. The uniform particle size can ensure that the animals can better ingest the feed when eating, reduce the picky eating phenomenon caused by different particle sizes, reduce the waste of feed, and thus improve the overall utilization rate of the feed.

[0033] In one embodiment of the present application, referring to Figure 1 As shown in the figure, the first sieve plate 71 is provided with a first hopper 711 at the lower end, and the second sieve plate 72 is provided with a second hopper 722 below.

[0034] In the above embodiment, in the process of screening the feed particles, the sieve holes of the first sieve plate 71 are larger than those of the second sieve plate 72, the large feed particles fall along the first sieve plate 71 into the first hopper 711, the feed particles passing through the first sieve plate 71 fall on the inclined second sieve plate 72 for re-screening, the feed particles that are too small to pass through the second sieve plate 72 enter the second hopper 722, the feed particles falling into the second hopper 722 are small in size, the feed particles that are uniform in size are more stable during storage and transportation, reducing the stratification phenomenon caused by the difference in particle size, facilitating management and use, and the feed in the first hopper 711 and the second hopper 722 can be put back into the extrusion cylinder 3 for re-shaping, improving the utilization efficiency of the feed raw materials.

[0035] In one embodiment of the present application, referring to Figure 1 As shown in the figure, the two side edges of the first sieve plate 71 and the second sieve plate 72 are respectively provided with a baffle 73.

[0036] In the above embodiment, the baffle 73 provided at the side edge of the sieve plate is used to prevent the feed particles from sliding off the side edge of the sieve plate to the ground during screening, which is contaminated and causes waste of feed, which is conducive to improving the utilization rate of the feed.

[0037] In one embodiment of the present application, referring to Figure 1 As shown in the figure, the lower end surface of the first hopper 711 is connected with a support column 74, and the side edge of the second hopper 722 is connected with the side edge of the support column 74.

[0038] In the above embodiment, the support column 74 connected with the lower end surface of the first hopper 711 is used to support the first hopper 711, which is conducive to improving the stability of the first hopper 711, in addition, the side edge of the second hopper 722 is connected with the side edge of the support column 74, which provides more fixed connection points for the second hopper 722, which is conducive to improving the stability of the fixed installation of the second hopper 722.

[0039] In one embodiment of the present application, referring to Figure 1 As shown in the figure, the support column 74 and the bottom end of the support frame 2 are provided with a pulley 8.

[0040] In the above embodiment, the pulley 8 installed at the bottom end of the support column 74 and the support frame 2 can be used to improve the motor flexibility of the granulator. Optionally, a self-locking mechanism is installed on the pulley 8 to prevent the granulator from sliding during work.

[0041] In one embodiment of the present application, referring to Figure 3 As shown in the figure, the stirring assembly 41 comprises a third motor 411, which is arranged at the upper end of the second cover plate 412, and is in transmission connection with a stirring rod 413, which extends into the stirring cavity 4. The side of the stirring cavity 4 is provided with a socket, and the socket is inserted with an insertion plate 43.

[0042] In the above embodiment, the third motor 411 drives the stirring rod 413 to stir in the stirring cavity 4, which is beneficial to improve the uniformity of the feed mixing. In addition, the socket is arranged at the side of the stirring cavity 4, and the insertion plate 43 is inserted in the socket. When stirring in the stirring cavity 4, the insertion plate 43 is inserted in the socket, which can block the feed in the stirring cavity 4 from falling into the extrusion cylinder 3, so that the stirring is more uniform. After the stirring is completed, the insertion plate 43 is pulled out, so that the feed in the stirring cavity 4 falls into the extrusion cylinder 3 for extrusion molding. It should be noted that the insertion plate 43 is not pulled out completely from the socket when it is pulled out, so as to avoid the feed from leaking out of the socket.

[0043] In one embodiment of the present application, referring to Figure 3 As shown in the figure, the stirring cavity 4 is connected with a liquid injection pipe 44 at the side of the upper end.

[0044] In the above embodiment, the liquid injection pipe 44 is used to inject liquid into the stirring cavity 4, so as to avoid the simultaneous injection of liquid and feed powder from the material injection port, which causes the adhesion of the feed powder and the liquid, resulting in the blockage of the main material port. The solid powder feed and the liquid are injected separately, which is beneficial to improve the injection efficiency of the feed, and further improve the production efficiency of the granulator.

[0045] In the actual use of the present application: the powdery feed such as grain, soybean meal, fish meal and the like is added into the stirring cavity 4 for mixing and stirring, the moisture content of the feed is adjusted according to the need, and the target moisture is usually 12%-15% to improve the formability of the particles. Optionally, for example, vitamins, minerals, medicines and the like can be added and uniformly mixed with the feed. After being stirred by the stirring assembly 41, the feed enters the extrusion cylinder 3. The auger blade 33 is in a spiral shape, and when the auger blade 33 rotates in the extrusion cylinder 3, the feed in the extrusion cylinder 3 can be pushed to the leak hole plate 31 arranged at one end of the extrusion cylinder 3. After being extruded, the feed is extruded and comes out from the leak hole of the leak hole plate 31. The extrusion cylinder 3 is provided with a supporting rod 5, and the second motor 51 is arranged on the supporting rod 5. The second motor 51 is in transmission connection with the cutting rod 52, and the second motor 51 drives the cutting rod 52 to reciprocate up and down on the end face of the leak hole plate 31. The feed extruded and coming out from the leak hole is cut into particles by the cutting rod 52. The other side of the extrusion cylinder 3 is provided with a hot air machine 6, and the air outlet of the hot air machine 6 faces the leak hole plate 31, which is used for heating the feed coming out from the leak hole plate 31 to accelerate the evaporation of the moisture in the formed feed, which is helpful for the rapid formation of the feed particles. Then the formed feed particles are screened by the sieve plate to ensure the uniformity of the pellet feed.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can modify the technical solutions described in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
