[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-8 The present invention provides a technical solution: a livestock and poultry feed pellet mill, including an upper body 1 and a lower body 4. The upper body 1 and the lower body 4 are connected by a hinge 5 to form a flip structure. A fastening component for fixing the connection between the upper body 1 and the lower body 4 is also provided, and the fastening component is evenly distributed on the outside of the connection between the upper body 1 and the lower body 4.

[0027] Furthermore, the fastening assembly includes a rotating screw 6, a limiting block 7, a locking block 8, and a nut 9. The rotating screw 6 is movably mounted on the outside of the upper body 1, and the limiting block 7 is fixed on the outside of the lower body 4. The locking block 8 is connected through the rotating screw 6. The inner dimension of the locking block 8 is adapted to the lower dimension of the limiting block 7. The locking block 8 can strengthen the connection between the rotating screw 6 and the limiting block 7, ensuring a stable connection between the two. The nut 9 is installed on the rotating screw 6 and is located below the locking block 8, which facilitates the fastening of the connection between the rotating screw 6 and the limiting block 7.

[0028] The upper body 1 has a feed inlet 3 on its outer side. A motor 2 is installed on the upper end of the upper body 1. An upper rotating shaft 11 is fixed at the output end of the motor 2. A pressure roller 13 is installed at the lower end of the upper rotating shaft 11.

[0029] Furthermore, a stabilizing frame 12 is fixed inside the upper body 1. The stabilizing frame 12 is connected to the upper rotating shaft 11 by a bearing. The stabilizing frame 12 is located on the upper side of the pressure roller 13 to ensure the stable rotation of the upper rotating shaft 11, thereby achieving the stable rotation of the pressure roller 13.

[0030] A second motor 18 is installed on the bottom inner side of the lower body 4. A lower rotating shaft 20 is fixed on the output end of the second motor 18. A connecting seat 23 is installed on the upper end of the lower rotating shaft 20 through a bearing. An extrusion disc 14 is fixedly installed on the upper side of the connecting seat 23 through a fixing bolt 22. The extrusion disc 14 is located inside the lower body 4. An inclined feeding plate 19 is fixed inside the lower body 4. A discharge port 10 is opened on the lower body 4. The lowest point of the feeding plate 19 is aligned with and connected to the discharge port 10.

[0031] Furthermore, a baffle 21 is fixed on the inner side of the lower body 4, and an extrusion disc 14 is connected to the upper side of the baffle 21. The outer diameter of the extrusion disc 14 is equal to the inner diameter of the lower body 4, so that the extrusion disc 14 is stable, thereby ensuring that the material extrusion operation is stable.

[0032] Furthermore, the pressure roller 13 has a rotating structure at the lower end of the upper rotating shaft 11. When the upper body 1 and the lower body 4 are in the closed state, the lower side of the pressure roller 13 contacts the upper side of the extrusion disc 14 to ensure that the extrusion operation is carried out normally.

[0033] The outer side of the lower rotating shaft 20 is provided with a scraping component for adjusting the particle length.

[0034] Furthermore, the scraping assembly includes a movable sleeve 15, a scraper 16, and a second nut 17. The movable sleeve 15 is sleeved on the lower rotating shaft 20. The scraper 16 is fixed on the outer side of the upper end of the movable sleeve 15. The lower end of the movable sleeve 15 is connected to the second nut 17 through a bearing. The second nut 17 is threadedly connected to the lower rotating shaft 20, and can move up and down on the lower rotating shaft 20 through the threaded connection, thereby driving the movable sleeve 15 to move up and down on the lower rotating shaft 20.

[0035] Furthermore, the movable sleeve 15 is provided with a key, and the lower rotating shaft 20 is provided with a matching keyway on its outer side. The movable sleeve 15 is connected to the lower rotating shaft 20 by a threaded connection between the nut 17 and the lower rotating shaft 20, forming a stable up-and-down movement structure on the lower rotating shaft 20. This ensures that the movable sleeve 15 can only move up and down on the lower rotating shaft 20 and cannot rotate, thus ensuring that the movable sleeve 15 can rotate synchronously with the lower rotating shaft 20.

[0036] Furthermore, the movable sleeve 15 passes through the feed plate 19, and the movable sleeve 15 is slidably connected to the feed plate 19 to ensure that the movable sleeve 15 can move up and down and rotate normally.

[0037] Working principle: When using this livestock and poultry feed pellet mill, firstly, fix the appropriate size extrusion disc 14 to the connecting seat 23 with the fixing bolt 22, then close the upper body 1, and rotate the rotating screw 6 on the outside of the upper body 1 downward. The rotating screw 6 is embedded in the limiting block 7. Rotate the nut 9 on the rotating screw 6 to make the locking block 8 lock on the lower side of the limiting block 7 to ensure a stable connection between the rotating screw 6 and the limiting block 7. Then tighten the nut 9 to achieve a tight connection between the upper body 1 and the lower body 4.

[0038] Then start motor 12. Motor 12 drives pressure roller 13 to rotate on extrusion disc 14 through upper rotating shaft 11. The stabilizer 12 in upper body 1 can ensure the stable rotation of pressure roller 13.

[0039] When the pressure roller 13 is rotating, the crushed feed raw material enters the upper body 1 through the feed inlet 3. Through the rotation of the pressure roller 13 and the extrusion disc 14, the crushed material can be squeezed out from the through hole on the extrusion disc 14. The material is in the form of a long strip on the lower side of the extrusion disc 14. At the same time, when the pressure roller 13 is rotating and squeezing on the extrusion disc 14, the outer side of the extrusion disc 14 is supported by the side guard 21, and the middle part is supported by the lower rotating shaft 20, which can ensure the stable working state of the extrusion disc 14.

[0040] Then, the second motor 18 is started synchronously, driving the lower rotating shaft 20 inside the lower body 4. The upper end of the lower rotating shaft 20 is connected to the bearing of the connecting seat 23 to ensure the normal rotation of the lower rotating shaft 20. When the lower rotating shaft 20 is rotating, it can drive the movable sleeve 15 to rotate. The scraper 16 at the upper end of the movable sleeve 15 will rotate under the extrusion disc 14, thereby cutting the extruded long strip of material into feed pellets, which are finally discharged from the device through the feeding plate 19 and the discharge port 10.

[0041] When it is necessary to adjust the length of the feed pellets, the nut 17 at the lower end of the movable sleeve 15 can be rotated to adjust the position of the movable sleeve 15 on the lower rotating shaft 20, thereby changing the distance between the scraper 16 and the lower side of the extrusion disc 14, thus achieving the adjustment of the feed pellet length.

[0042] The above describes the working process of the feed pellet mill. Any content not described in detail in this manual is existing technology known to those skilled in the art.

[0043] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
