Technical Field

[0001] The utility model relates to the field of pelletizers, in particular to a feed pelletizer. Background Art

[0002] A feed pelletizer is a mechanical device used for producing granular feed, which is widely applied in the livestock industry and aquaculture industry for processing various animal feeds. The background art of pelletizers involves multiple fields, including mechanical engineering, materials science, agricultural engineering, etc. Before pelletizing the feed, the raw materials need to go through the processes of crushing and mixing to ensure the uniformity of the pellets and the consistency of the nutritional components. The crushing technology involves different types of crushers, such as hammer mills, gear mills, etc. The mixing technology includes equipment such as mixers and blenders. The appropriate moisture content of the raw materials is crucial for the pelletizing process. Excessive or insufficient moisture will affect the quality of the pellets. Therefore, the moisture control technology of the raw materials is a key link in the pelletizing process. Finally, the feed pelletizer presses the mixed raw materials into pellets with a certain shape and strength through extrusion.

[0003] When the die holes of the pelletizer in the prior art are blocked, the die needs to be disassembled for dredging. The disassembly process is very cumbersome, and the sealing performance of the die will also be affected after multiple disassembly. The utility model solves the above problems.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] In the present device, the so-called rotational connection means that by baking the bearing on the shaft, a spring retaining ring groove is provided on the shaft or the shaft hole, and the axial fixation of the bearing is realized by clamping the elastic retaining ring in the retaining ring groove to achieve rotation; the so-called hinged connection means a connection method that moves on connection parts such as hinges, pin shafts, and short shafts.

[0017] The present utility model will be described in detail below with reference to the accompanying drawings.

[0018] Embodiment 1:

[0019] Next, in combination with the attached Figure 1-2 This embodiment of a feed granulator will be described, including: an extrusion barrel 1, a spiral blade is provided inside the extrusion barrel 1, the spiral blade can extrude the feed to the end of the extrusion barrel 1, an installation thread 2 is provided on the outer surface of the end of the extrusion barrel 1, an extrusion die 3 is in contact with the end of the extrusion barrel 1, an installation thread 2 is provided on the extrusion die 3, the two installation threads 2 can be connected continuously, and a sealing threaded ring 4 is threadedly connected to the installation thread 2 of the extrusion die 3;

[0020] When assembling or replacing the extrusion die 3, the extrusion die 3 is coaxially arranged with the extrusion barrel 1, the two installation threads 2 are connected in succession, the sealing thread ring 4 is rotated, and the sealing thread ring 4 is displaced along the installation thread 2 to the joint of the extrusion die 3 and the extrusion barrel 1, so that the assembly of the extrusion die 3 can be completed. The installation is very convenient. Through the cooperation of the internal thread of the sealing thread ring 4 and the external thread of the installation thread 2, the sealing effect is very good.

[0021] The extrusion die 3 is connected to the die holder 5. The extrusion die 3 is provided with a plurality of holes that are evenly distributed circumferentially around the axis of the die holder 5. The die holder 5 is connected to the rotating shaft 6. The rotating shaft 6 is rotatably connected in the bearing seat 7. The bearing seat 7 is connected to the extrusion barrel 1;

[0022] When replacing the extrusion die 3, the sealing thread ring 4 is unscrewed, and the extrusion die 3 is rotated. The extrusion die 3 drives the die holder 5 and the rotating shaft 6 to rotate. When the extrusion die 3 is coaxial with the extrusion barrel 1, the two installation threads 2 are connected in succession, that is, there is no need to manually carry the extrusion die 3, nor to adjust the angle of the extrusion die 3, reducing the assembly difficulty.

[0023] The die hole sizes and shapes of each extrusion die 3 are different;

[0024] It is convenient to adjust the granulation size and shape.

[0025] There are three extrusion dies 3. When one extrusion die 3 is assembled with the extrusion barrel 1, the lower surfaces of the sealing thread rings 4 of the other two extrusion dies 3 can coincide with the inner arc surfaces of the corresponding positioning arc plates 8. The positioning arc plates 8 are slidably connected in the plate frame 9. The plate frame 9 is connected to the extrusion barrel 1. The other end of the positioning arc plate 8 is in the area of the telescopic end of the cylinder 10.

[0026] When replacing the extrusion die 3, control the two cylinders 10 to contract, the positioning arc plates 8 contract, and the extrusion die 3 is no longer restricted and starts to rotate. When it rotates to the extrusion die 3 being close to coaxial with the extrusion barrel 1, control one cylinder 10 to extend, rotate the extrusion die 3, so that the lower surface of the sealing thread ring 4 coincides with the inner arc surface of the positioning arc plate 8. At this time, control the other cylinder 10 to extend. At this time, the two sealing thread rings 4 are positioned by the two positioning arc plates 8, and the lower extrusion die 3 is automatically coaxial with the extrusion barrel 1, further reducing the assembly difficulty.
