[0024] See also Figure 1 As shown, the existing feed pelletizer generally includes a bottom bracket 1, a nylon caster 2 is installed under the bottom bracket 1, a base 3 and a driving motor 4 are installed on the bottom bracket 1, a coupling 26 is arranged between the base 3 and the driving motor 4, a cavity is arranged in the base 3, a transmission component is arranged in the cavity of the base 3, and the transmission component includes a direction-changing gear set, and the transmission component is connected to the driving motor 4 through the coupling 26. A material distribution component, a granulation component and a lower hopper 5 are arranged on the base 3, and the lower hopper 5, the granulation component and the material distribution component are arranged vertically in sequence and form a butt joint, and the raw material enters the granulation component from the lower hopper 5, is granulated by the granulation component, and is finally discharged by the material distribution component;

[0025] The material distribution component includes a cylindrical body, on which a discharge port 6 is arranged, and a distribution plate is arranged inside the body, and the distribution plate is located above the discharge port 6. The transmission assembly is connected to a vertically arranged transmission shaft 7, and the transmission shaft 7 passes through the distribution plate and is fixedly connected to the distribution plate. When the driving motor 4 is working, the transmission assembly can drive the transmission shaft 7 to rotate. When the transmission shaft 7 rotates, it will drive the distribution plate to rotate, and the granular feed formed by the granulation component is discharged from the discharge port 6 under the action of centrifugal force;

[0026] The granulating part includes an upper cylinder body 8, which is butt-jointed with the machine body through a flange ring. A circular die plate is arranged inside the upper cylinder body 8, and a discharge hole is provided on the circular die plate. A transmission shaft 7 passes through the circular die plate and is fixedly connected with the circular die plate. Meanwhile, a flat frame 9 with a "cross" structure is fixed inside the upper cylinder body 8, and the flat frame 9 is located above the circular die plate. A rotatable pressing roller 10 is sleeved on the flat frame 9, and there is a gap between the pressing roller 10 and the circular die plate. The lower end of the lower hopper 5 is butt-jointed with the upper end of the upper cylinder body 8. After the mixed feed enters, it will be located between the pressing roller 10 and the circular die plate. As the circular die plate rotates, the feed between the two will be squeezed, and the feed will be squeezed out from the discharge hole on the circular die plate to form granular feed.

[0027] See also Figures 2 to 3 As shown, since the feed to be pelletized has a certain viscosity after fumigation, the feed is easy to clump and block the circular die plate or directly block above the flat frame 9, resulting in the feed being unable to fall on the circular die plate. Therefore, the present application sets a dredging component in the upper cylinder 8, and the dredging component is located above the circular die plate. The dredging component stirs and dredges the feed entering the lower hopper 5 to prevent the feed from being blocked;

[0028] The dredging component includes a central shaft rod 11, and a perforation is arranged at the center position of the flat frame 9. The central shaft rod 11 passes through the perforation and docks with the upper end of the transmission shaft 7. When the transmission shaft 7 rotates, the central shaft rod 11 can be driven to rotate, and a conical cap 12 is fixed to the upper end of the central shaft rod 11, and a horizontally arranged lever arm 13 is fixed on the conical cap 12. At this time, the lever arm 13 can move with the rotation of the transmission shaft 7, which has a stirring effect on the feed. At the same time, an inclined diagonal support rod 14 is arranged on the cylinder wall of the upper cylinder body 8. The lower end of the diagonal support rod 14 is fixedly connected to the upper cylinder body 8, and the high end of the diagonal support rod 14 is axially connected with a rotating lever 15. The rotating lever 15 can rotate around the shaft joint. When the driving motor 4 rotates with the transmission shaft 7, the lever arm 13 starts to rotate, and the lever arm 13 will rotate while rotating. While breaking up the feed, the feed on the granulation component is stirred, thereby avoiding the situation where the feed causes blockage of the machine.

[0029] See also Figures 4 to 6 As shown, the above scheme is suitable for the situation that the feed is blocked in the upper cylinder body 8. When the discharge hole on the circular die plate is blocked with hard objects, the circular die plate needs to be removed for cleaning in the traditional structure, which is troublesome. Therefore, the circular die plate is arranged into a double-layer structure in this scheme, that is, the circular die plate includes an upper die plate 16 and a lower die plate 17. The discharge holes on the upper die plate 16 and the lower die plate 17 correspond to each other. When the machine is blocked, it is only necessary to stagger the upper die plate 16 and the lower die plate 17 to form a relative displacement, which can break the hard objects in the discharge hole and achieve the purpose of unblocking.

[0030] The diameter of the lower die plate 17 is slightly smaller than that of the upper die plate 16. The transmission shaft 7 passes through the center of the upper die plate 16, and the transmission shaft 7 is fixedly connected to the upper die plate 16. A strip notch 18 is provided on the lower die plate 17. The width of the strip notch 18 is consistent with the diameter of the transmission shaft 7. The transmission shaft 7 passes through the notch on the lower die plate 17. When the discharge hole on the upper die plate 16 corresponds to the discharge hole on the lower die plate 17, the inner end of the strip notch 18 contacts the transmission shaft 7. At this time, the central axis of the transmission shaft 7 is aligned with the lower die plate 16. There is a horizontal distance greater than zero between the center points of the lower mold plate 17 and the transmission shaft 7 (that is, the lower mold plate 17 is eccentrically connected to the transmission shaft 7). A bottom support seat 19 is provided below the lower mold plate 17. The bottom support seat 19 is fixed on the transmission shaft 7, and a radially extending slide groove 20 is provided on the bottom support seat 19. A limiting protrusion 21 is fixed on the lower surface of the lower mold plate 17. The limiting protrusion 21 is in the shape of a long strip. The limiting protrusion 21 is fitted in the slide groove 20 and the limiting protrusion 21 is parallel to the strip notch 18, so that the lower mold plate can rotate with the transmission shaft 7. A compression return spring 22 is also arranged in the strip notch 18, one end of the compression return spring 22 is fixedly connected to the transmission shaft 7, and the other end is fixedly connected to the end of the strip notch 18. When the discharge hole on the lower die plate 17 corresponds to the discharge hole on the upper die plate 16, the compression return spring 22 is in a normal state, and a threaded through hole is arranged on the upper barrel 8. The threaded through hole and the lower die plate 17 are on the same horizontal plane. A locking bolt passes through the threaded through hole. When the granulator is working normally before being blocked, the end of the locking bolt is not When the machine enters the upper cylinder body 8, the transmission shaft 7 rotates when the machine is working normally, and the bottom support seat 19 drives the lower mold plate 17 to rotate. When the machine is blocked, the lower mold plate 17 is adjusted to the strip notch 18 on the extension line of the locking bolt 23, and then the locking bolt 23 is screwed to make the inner end of the locking bolt 23 enter the upper cylinder body 8. At this time, the locking bolt 23 pushes the lower mold plate 17, causing the upper mold plate 16 and the lower mold plate 17 to move relative to each other, thereby clearing and unblocking the blocked part in the discharge hole on the circular mold plate.

[0031] A blade disc 24 is fixedly connected to the wall of the upper cylinder body 8. The blade disc 24 is in a long strip shape and in a horizontal state. A blade 25 is installed on the blade disc 24. As the circular die disc rotates, the extruded feed moves and contacts the blade 25, and is cut into feed of a certain length by the blade 25.

[0032] When the above-mentioned feed pelletizing machine is working, first align the lower hopper 5 with the feeding component, and the feed first passes through the dredging component through the lower hopper 5. The dredging component stirs and dredges the feed entering the machine to prevent blockage during the feeding process. A pressing roller 10 and a circular die plate are also provided in the upper cylinder body 8. Then the feed will fall into the position between the pressing roller 10 and the circular die plate, and will be squeezed between the two, and the feed will be squeezed out from the discharge hole on the circular die plate to form granular feed. Finally, as the circular die plate rotates, the extruded feed is cut into granular feed of a certain length by a cutter.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
