Description

Technical Field

[0001] This utility model belongs to the field of feed production technology, and in particular relates to a feed pelleting machine with adjustable pellet diameter. Background Technology

[0002] Feed is food used to feed animals, including plant-based feed and animal-based feed. A feed pellet mill is a mechanical device used for feed processing. It can directly press various raw materials into pellets after crushing, thereby improving feed density and nutrient absorption rate, and facilitating storage and transportation. Therefore, it is widely used in the production and processing of various feeds.

[0003] Chinese patent disclosure (CN210646267U) describes an adjustable-particle-size pig feed pellet mill. The mill includes a base, a pelleting platform on its upper surface, a cover plate on the front surface of the pelleting platform, and a motor on its rear surface. A rotating shaft is tightly welded to one end of the motor's output end, which extends into a groove. A spiral pusher is mounted on the rotating shaft. A cylinder is installed on one end of the base near the front surface of the pelleting platform, and a feeding plate is tightly welded to the output end of the cylinder. A cutting blade is tightly welded to the upper surface of one end of the feeding plate. This adjustable-particle-size pig feed pellet mill allows for the production of feed pellets with different particle diameters by changing the cover plate with different outlet diameters according to production needs. Furthermore, adjusting the cylinder's extension and retraction frequency can change the feed pellet length, thus solving the problem of inconvenient adjustment of feed pellet size in pellet mills.

[0004] However, the above solution uses bolts to replace the cover plate, and the bolt fixing means that each disassembly and assembly must be done with tools such as screwdrivers, which increases the cumbersomeness of disassembly and assembly to a certain extent. This makes it difficult for workers to quickly replace the discharge mold plate, resulting in inconvenience in its use. Therefore, it is necessary to design a feed pellet mill with adjustable particle diameter. Utility Model Content

Afterwards, the groove facilitates the sliding removal or installation of the discharge mold plate from the surface of the connecting rod, avoiding the cumbersome and inconvenient disassembly and replacement of the discharge mold plate caused by the traditional bolt fixing. This allows for the quick replacement of discharge mold plates of different specifications to produce feed with different particle diameters, improving its practicality.

[0019] 2. The rotation of the mounting sleeve will drive the drive rod to rotate, periodically contacting the rotating fixed block to lower the discharge hopper. Then, using the elastic force of the fixed spring, the discharge hopper can rise again. The up-and-down vibration of the discharge hopper will achieve the vibration discharge of feed, avoiding excessive accumulation of feed on the bottom wall of the discharge hopper, which would cause inconvenience in discharge, and improving the feed discharge rate, which is convenient for feed pelleting production.

[0028] Example 1

[0029] A preferred embodiment of the feed pelleting machine with adjustable particle diameter provided by this utility model is, for example... Figures 1 to 5As shown: A feed pellet mill with adjustable pellet diameter includes a base plate 5; a controller 11 fixedly connected to one side of the top of the base plate 5, with fixed frames 4 symmetrically fixedly connected to the top of the base plate 5; a machine body 2 fixedly connected to the top of the two fixed frames 4, with a feed hopper 1 fixedly connected to one side of the top of the machine body 2, and a through groove 20 opened on the other side of the machine body 2, with a discharge mold plate 8 movably connected inside the through groove 20; and an installation component 9 assembled on one side inside the machine body 2, which is used to realize quick assembly and disassembly between the discharge mold plate 8 and the inside of the through groove 20; A drive motor 3 is fixedly connected to one side of the machine body 2. The output end of the drive motor 3 extends into the interior of the machine body 2 and is fixedly connected to a spiral push rod 10 via a coupling. One end of the spiral push rod 10 is fixedly connected to a connecting rod 12 that passes through the discharge mold plate 8. A mounting sleeve 13 is slidably connected to the surface of the connecting rod 12. A cutting blade 19 is fixedly connected to one end of the surface of the mounting sleeve 13. A discharge hopper 7 is set on one side of one of the fixed frames 4. A vibration assembly 6 is assembled on one side of one of the fixed frames 4. The vibration assembly 6 is used to realize the vibration discharge of the discharge hopper 7.

[0030] The mounting component 9 includes: a slot 907 formed on the upper part of one side inside the body 2, and an installation groove 906 formed inside the body 2 above the slot 907; a mounting block 905 movably connected inside the installation groove 906, with the bottom end of the mounting block 905 extending into the inside of the slot 907, and a pull rod 903 extending to the outside of the body 2 fixedly connected to the top end of the mounting block 905; a mounting spring 909 wound around the surface of the pull rod 903, with both ends of the mounting spring 909 fixedly connected to the top end of the mounting block 905 and the inner top wall of the installation groove 906, respectively; and a locking block 902 fixedly connected to the top end of the discharge mold plate 8, with an installation hole 901 formed at the top end of the locking block 902.

[0031] It should be noted that some existing feed pellet mills with adjustable particle diameter still have certain shortcomings in actual use. The above solution uses bolts to replace the cover plate, and the bolt fixing means that each disassembly and assembly must be done with tools such as screwdrivers, which increases the cumbersomeness of disassembly and assembly to a certain extent and makes it difficult for workers to quickly replace the discharge mold plate 8, resulting in inconvenience in its use.

[0032] In this embodiment, different discharge mold plates 8 are selected according to the required diameter of the granulated feed pellets. The fixing bolt 17 is rotated until it is completely disengaged from the bolt hole 14. Then, the mounting sleeve 13 is slid off the surface of the connecting rod 12. Next, the mounting block 905 is raised by the pull rod 903 to compress the mounting spring 909 until it is completely disengaged from the mounting hole 901. Then, using the groove 16, the user can pinch the discharge mold plate 8 with their fingers and slide it off. When installing a new discharge mold plate 8, the pull rod 903 is pulled first, and then the discharge mold plate 8 is placed on the surface of the connecting rod 12, causing the locking block 902 to engage with the slot 907. The pull rod 903 is then released, and the elastic force of the mounting spring 909 causes the mounting block 905 to descend and engage with the mounting hole 901, achieving a firm engagement and fixation between the discharge mold plate 8 and the through groove 20. This allows for quick assembly and disassembly of the discharge mold plate 8. Finally, the mounting sleeve 13 is placed on the connecting rod 12. The connecting rod 12 is connected to the surface of the connecting rod 12, and the limiting strip 18 is engaged with the limiting groove 15 until the cutting blade 19 is in close contact with the surface of the discharge mold plate 8. Then, the fixing bolt 17 is tightened into the bolt hole 14 to achieve a firm fit between the mounting sleeve 13 and the surface of the connecting rod 12. Then, the feed raw materials are added into the feed hopper 1 and conveyed into the machine body 2. At this time, the drive motor 3 is started to drive the spiral push rod 10 to rotate, which can then spirally agitate the feed raw materials and use the discharge mold plate 8 to compress the feed raw materials into cylindrical strips. At the same time, the rotation of the spiral push rod 10 will drive the connecting rod 12 to rotate, which in turn drives the mounting sleeve 13 and the cutting blade 19 to rotate, so that the feed can be cut to achieve the granulation process of the feed. The cut feed falls to the top of the discharge hopper 7 and is guided out by the discharge hopper 7. At the same time, the vibration component 6 can realize the vibration discharge of the discharge hopper 7 to avoid the feed accumulating on the bottom wall of the discharge hopper 7 and causing subsequent discharge obstruction.

[0033] In a further preferred embodiment of the present invention, the card block 902 and the card slot 907 form an engaging structure, and the shapes of the card block 902 and the card slot 907 are inverted convex.

[0034] In this embodiment, the engagement between the inverted convex locking block 902 and the slot 907 improves the firmness and stability of the initial engagement between the discharge mold plate 8 and the through groove 20.

[0035] In a further preferred embodiment of the present invention, the bottom end of the mounting block 905 and the top end of the mounting hole 901 form an engaging structure, and the length of the mounting block 905 is less than the depth inside the mounting groove 906.

[0036] In this embodiment, the bottom end of the mounting block 905 engages with the inside of the mounting hole 901 to achieve a secure engagement between the locking block 902 and the inside of the locking slot 907.

[0037] In a further preferred embodiment of the present invention, a reserved groove 908 is provided on the inner wall of the mounting groove 906, and a reserved block 904 is fixedly connected to the upper ends of both sides of the mounting block 905, which slides in cooperation with the interior of the reserved groove 908.

[0038] In this embodiment, the sliding of the reserved block 904 inside the reserved groove 908 is used to improve the smoothness of the up-and-down sliding of the mounting block 905.

[0039] In a further preferred embodiment of the present invention, a groove 16 is provided on one side of the body 2 at both ends of the through groove 20, and the groove 16 is arc-shaped.

[0040] In this embodiment, the arc-shaped groove 16 is used to facilitate the user's fingers to pinch the discharge mold plate 8 through the groove 16 for sliding assembly and disassembly.

[0041] Example 2

Figures 1 to 5 As shown: the vibration assembly 6 includes: a fixing groove 602 symmetrically opened on one side of one of the fixing frames 4, with a slide rod 605 fixedly connected to the inner wall of the fixing groove 602; a slider 603 slidably connected to the surface of the slide rod 605, with one side of the slider 603 fixedly connected to one side of the discharge hopper 7; a fixing spring 604 wound around the surface of the slide rod 605, with both ends of the fixing spring 604 fixedly connected to the bottom wall of the fixing groove 602 and the bottom end of the slider 603 respectively; a fixing block 601 fixedly connected to one side of the bottom wall of the discharge hopper 7; and a drive rod 606 fixedly connected to one side of the surface of the mounting sleeve 13.

[0043] In this embodiment, the rotation of the mounting sleeve 13 will drive the drive rod 606 to rotate, periodically contacting the fixed block 601. This causes the discharge hopper 7 to descend, causing the slider 603 to slide on the surface of the slide rod 605 and compress the fixed spring 604. After the drive rod 606 rotates and separates from the fixed block 601, the elastic force of the fixed spring 604 can be used to make the slider 603 rise, causing the discharge hopper 7 to rise. Thus, the up-and-down vibration of the discharge hopper 7 can achieve the vibration discharge of feed, avoiding excessive accumulation of feed on the bottom wall of the discharge hopper 7, which would cause inconvenience in discharging.

[0044] In a further preferred embodiment of the present invention, the fixing block 601 is arc-shaped, and the fixing block 601 and the driving rod 606 are in the same vertical plane.

[0045] In this embodiment, an arc-shaped fixing block 601 is used to make it easier to rotate and contact with the drive rod 606, which facilitates the up-and-down vibration discharge of the discharge hopper 7.

[0046] In a further preferred embodiment of this utility model, the discharge hopper 7 is U-shaped, and the inclination angle between the inner bottom wall of the discharge hopper 7 and the horizontal direction is thirty degrees.

[0047] In this embodiment, the inclined discharge hopper 7 is used to facilitate smoother discharge of feed.

[0048] In a further preferred embodiment of the present invention, a limiting groove 15 is formed on the surface of the connecting rod 12, and a limiting strip 18 that slides and engages with the inside of the limiting groove 15 is fixedly connected to the inner wall of the mounting sleeve 13.

[0049] In this embodiment, the sliding fit between the limiting strip 18 and the limiting groove 15 is used to improve the firmness and stability of the sleeve between the mounting sleeve 13 and the connecting rod 12.

[0050] In a further preferred embodiment of the present invention, a fixing bolt 17 is movably connected to one side of the mounting sleeve 13, and a bolt hole 14 that is threadedly engaged with the fixing bolt 17 is provided on one side of the connecting rod 12.

[0051] In this embodiment, the threaded engagement between the fixing bolt 17 and the bolt hole 14 improves the firmness and stability of the mounting sleeve 13 and the surface of the connecting rod 12.

[0052] In summary, the vibration component 6 is used to realize the vibration discharge of the discharge hopper 7, which improves the smoothness of discharge. At the same time, the installation component 9 is used to realize the quick assembly and disassembly between the discharge mold plate 8 and the through groove 20, avoiding the cumbersome and inconvenient disassembly and replacement of the discharge mold plate 8 caused by the traditional bolt fixing.
