Description

Technical Field

[0001] This invention relates to the field of chicken feed, specifically to a high-efficiency chicken feed pelleting device and pelleting method. Background Technology

[0002] Chicken is a common food ingredient. China consumes 5 billion white-feathered chickens a year, which requires good livestock production. Chicken farming requires a lot of chicken feed, which is made from raw materials such as corn, soybean meal, and wheat bran. Pelleted chicken feed is easier for chickens to eat, so feed pellet mills are needed. However, existing feed pellet mills still have some shortcomings in use.

[0003] Currently available feed pellet mills are not convenient for quick adjustment of feed pellet size during use, and require multiple feedings. They cannot adjust the size of chicken feed according to needs, resulting in low adjustability. Furthermore, they cannot automatically feed after pelleting, leading to low production efficiency. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstract and title of the present application, to avoid obscuring the purpose of this section, the abstract and the title of the invention.

[0005] In view of the problems existing in the current chicken feed pellet mill, the present invention is proposed.

[0006] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: a high-efficiency pelleting device for chicken feed production, comprising a base, support columns fixedly arranged around the upper surface of the base, a support plate fixedly connected above the support columns, a fixing block fixedly arranged above the support plate, an outer cylinder fixedly connected to the top of the fixing block, a cutting assembly installed on the side of the outer cylinder, an extrusion assembly arranged inside the outer cylinder, a suspension frame arranged above the extrusion assembly, an automatic feeding assembly installed inside the extrusion assembly, a first top cylinder fixedly connected to the top of the outer cylinder, a second top cylinder fitted inside the first top cylinder, and an inner cylinder fixedly connected to the bottom of the second top cylinder.

[0009] In a preferred embodiment of the high-efficiency chicken feed pelleting device of the present invention, the cutting assembly includes a motor fixedly installed below a support plate, a connecting plate fixedly connected to the output shaft of the motor, a connecting shaft fixedly connected to the front end of the connecting plate, a docking plate fixedly provided on the side of the connecting shaft, a scraper fixedly provided on the surface of the docking plate, and a pusher plate fixedly installed below the docking plate.

[0010] In a preferred embodiment of the high-efficiency chicken feed pelleting device of the present invention, the connecting plate, connecting shaft, pusher plate, docking plate and scraper are integral, the outer walls of the docking plate and scraper are in contact with the outer wall of the outer cylinder, and the outer wall of the pusher plate is in contact with the outer wall of the fixing block.

[0011] In a preferred embodiment of the high-efficiency chicken feed pelleting device of the present invention, the extrusion assembly includes a fixed rod fixedly installed above a connecting plate, a reciprocating screw fixedly connected to the top of the fixed rod, an extrusion disc installed on the outer side of the reciprocating screw, a first baffle fixedly installed in the middle of the extrusion disc, a second baffle fixedly installed on the edge of the extrusion disc, and limit rods extending through both the left and right sides of the extrusion disc. The limit rods are fixedly connected to the suspension, and the extrusion disc forms a reciprocating lifting structure with the outer cylinder through the reciprocating screw and the limit rods.

[0012] In a preferred embodiment of the high-efficiency chicken feed pelleting device of the present invention, the automatic feeding assembly includes a feed inlet opened inside the extrusion disc, side plates are fixedly installed on both the left and right sides of the inner wall of the feed inlet, a spring is fixedly installed above the side plate, an overlapping plate is fixedly installed above the spring, a pressure block is fixedly connected to the bottom end of the overlapping plate, and a connecting column is fixedly installed on the lower surface of the suspension.

[0013] As a preferred embodiment of the high-efficiency chicken feed production pelleting device of the present invention, the position of the connecting column corresponds to the position of the feed inlet, the diameter of the connecting column is smaller than the inner diameter of the feed inlet, the upper part of the pressing block is conical in shape, and the pressing block forms a telescopic structure with the extrusion plate, the connecting column and the side plate.

[0014] In a preferred embodiment of the high-efficiency chicken feed pelleting device of the present invention, a folding plate is fixedly provided on the surface of the second top cylinder, and bolts are installed on the internal threads of the folding plate. The second top cylinder and the inner cylinder form a pressing structure with the first top cylinder and the outer cylinder through the folding plate and the bolts.

[0015] A pelleting method for a high-efficiency chicken feed pelleting device mainly includes the following steps:

[0016] S1: The base, pillar, and support plate are used to support the entire device. The fixing block is used to support the outer cylinder and the inner cylinder. First, the feed raw materials are poured into the receiving cavity composed of the extrusion plate, the first baffle, and the second baffle. Then, the size of the feed pellets is adjusted as needed. By rotating the first top cylinder and the second top cylinder and the inner cylinder inside the outer cylinder, the overlapping area of ​​the holes between the outer cylinder and the inner cylinder changes. After the adjustment is completed, the bolts can be screwed into the inside of the first top cylinder and screwed in, so that the first top cylinder and the second top cylinder can be pressed together. At this time, the outer cylinder and the inner cylinder can be fixed, and the overlapping area of ​​the through holes on the outer cylinder and the inner cylinder changes, so that the size of the discharge can be adjusted before the device is used.

[0017] S2: The motor on the cutting assembly drives the connecting plate and the fixed rod to rotate. When the fixed rod rotates, it drives the reciprocating screw to rotate. When the reciprocating screw rotates, it drives the extrusion plate to move up and down on the outside of the limit rod, so that the device can extrude the material. This allows the device to extrude the feed through the through holes on the outer and inner cylinders, thus achieving the automatic discharge function.

[0018] S3: While the extrusion plate moves up and down, the position of the connecting column relative to the feed port changes. The overlapping plate inside the feed port can be pressed down by the feed port, thereby compressing the spring on the side plate and moving the pressure block down. Through the inclined surface of the pressure block, the material can automatically fall into the lower layer of the extrusion plate, realizing the function of automatic feeding while extruding the material.

[0019] S4: Since the connecting plate, connecting shaft, pusher plate, docking plate and scraper are integrated into one unit, the device can drive the connecting plate, connecting shaft, pusher plate, docking plate and scraper to rotate synchronously through the output shaft of the motor. The scraper cuts the extruded feed into pellets, and the inclined surface of the pusher plate discharges the feed pellets to the outside, enabling the device to achieve high-efficiency pelleting function.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. Through the design of bolts, folding plates, inner cylinder, and outer cylinder, the device can rotate the inner cylinder and tighten the bolts during use, causing the inner and outer cylinders to be stably pressed together. At this time, the overlapping area of ​​the through holes on the inner and outer cylinders changes, allowing the device to change the size of the through holes at the discharge point when extruding feed, thereby changing the size of the feed pellets. This improves the device's performance and solves the problem of existing pellet mills being inconvenient to adjust pellet size during use, giving it a more functional advantage.

[0022] 2. Through the cutting component and reciprocating screw on the device, the device drives the reciprocating screw to rotate while cutting the pellets through the cutting component, so that the extrusion plate can move up and down back and forth, thereby extruding the material in the inner cylinder below the extrusion plate. This allows the feed to be extruded while the cutting component achieves automatic pelleting, improving the practicality of the device.

[0023] 3. Through the automatic feeding component on the device, the extrusion disc can abut against the overlapping plate through the connecting column during the up-and-down reciprocating motion, thereby causing the conical structure pressing block to move downward. The material will automatically flow downward through the inclined surface of the pressing block, realizing the automatic feeding function. This allows the device to automatically cut materials and automatically replenish feed raw materials while automatically extruding materials, improving the convenience of using the device.

[0048] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

[0050] Example

[0051] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0052] like Figure 1-7 As shown, a high-efficiency chicken feed pelleting device and pelleting method includes a base 1, with support columns 2 fixedly arranged around the upper surface of the base 1. A support plate 3 is fixedly connected above the support columns 2, and a fixing block 4 is fixedly arranged above the support plate 3. An outer cylinder 5 is fixedly connected to the top of the fixing block 4. A cutting component 6 is installed on the side of the outer cylinder 5. The cutting component 6 can pelletize the feed extruded from the through holes on the outer cylinder 5 through a driving device inside the device, improving the practicality of the device. An extrusion component 7 is arranged inside the outer cylinder 5. The extrusion component 7 can extrude the feed before the cutting component 6 pelletizes it, thereby improving the pelleting effect of the device. A suspension 8 is arranged above the extrusion component 7. An automatic feeding component 9 is installed inside the extrusion assembly 7. The automatic feeding component 9 enables the device to intermittently replenish feed during the up-and-down movement of the extrusion plate inside the extrusion assembly 7, thereby improving the production efficiency of the device and eliminating the need for manual replenishment of feed raw materials multiple times. A first top cylinder 10 is fixedly connected to the top of the outer cylinder 5. A second top cylinder 11 is fitted inside the first top cylinder 10. An inner cylinder 12 is fixedly connected to the bottom of the second top cylinder 11. The rotation angle between the inner cylinder 12 and the outer cylinder 5 can be adjusted, thereby changing the overlapping area of ​​the through holes on the inner cylinder 12 and the outer cylinder 5. At this time, the size of the extruded feed changes, allowing the device to change the size of the pellets at the discharge, thus improving the practicality of the device.

[0053] In this example, the base 1, support column 2, support plate 3, fixing block 4, outer cylinder 5 and first top cylinder 10 are integrated structures. The central axes of the base 1, support plate 3, fixing block 4, outer cylinder 5 and first top cylinder 10 are collinear, ensuring the overall stability of the device. The outer cylinder 5 facilitates subsequent extrusion of feed and automatic cutting.

[0054] In this example, through holes are uniformly provided on the surface of the outer cylinder 5 and the surface of the inner cylinder 12. The through holes on the inner cylinder 12 coincide with the through holes on the outer cylinder 5. The connection between the outer cylinder 5 and the inner cylinder 12 is a rotatable connection. By adjusting the angle between the outer cylinder 5 and the inner cylinder 12 on the device, the device can change the degree of overlap of the through holes on the outer cylinder 5 and the inner cylinder 12, thereby changing the size of the output material so as to adjust the size of the feed pellets in the future.

[0055] In this example, the cutting assembly 6 includes a motor 601 fixedly installed below the support plate 3. A connecting plate 602 is fixedly connected to the output shaft of the motor 601. A connecting shaft 603 is fixedly connected to the front end of the connecting plate 602. A docking plate 605 is fixedly installed on the side of the connecting shaft 603. A scraper 606 is fixedly installed on the surface of the docking plate 605. The docking plate 605 can drive the scraper 606 to rotate when the connecting shaft 603 rotates, thereby cutting the feed extruded through the through hole into pellets. A pusher plate 604 is fixedly installed below the docking plate 605, and the pelleted feed is pushed out through the pusher plate 604 on the device.

[0056] In this example, the connecting plate 602, connecting shaft 603, pusher plate 604, docking plate 605, and scraper 606 are integrated into one unit. The outer walls of the docking plate 605 and scraper 606 are in contact with the outer wall of the outer cylinder 5, and the outer wall of the pusher plate 604 is in contact with the outer wall of the fixing block 4, so that the connecting plate 602, connecting shaft 603, pusher plate 604, docking plate 605, and scraper 606 can rotate smoothly and maintain the integrity of the pellets.

[0057] In this example, the extrusion assembly 7 includes a fixed rod 701 fixedly installed above the connecting plate 602. A reciprocating screw 702 is fixedly connected to the top of the fixed rod 701. An extrusion disc 703 is installed on the outer side of the reciprocating screw 702. A first baffle 704 is fixedly installed in the middle of the extrusion disc 703. A second baffle 705 is fixedly installed on the edge of the extrusion disc 703. The first baffle 704, the second baffle 705, and the internal cavity of the extrusion disc 703 are used to place spare feed raw materials. Limiting rods 706 are provided through both the left and right sides of the extrusion disc 703. The limiting rods 706 are fixedly connected to the suspension 8. The extrusion disc 703 forms a reciprocating lifting structure with the outer cylinder 5 through the reciprocating screw 702 and the limiting rods 706. The reciprocating lifting structure on the device enables the extrusion disc 703 to extrude feed when it moves downward.

[0058] In this example, the automatic feeding assembly 9 includes a feed port 901 opened inside the extrusion plate 703. Side plates 902 are fixedly installed on both the left and right sides of the inner wall of the feed port 901. A spring 903 is fixedly installed above the side plate 902. An overlapping plate 904 is fixedly installed above the spring 903. A pressure block 905 is fixedly connected to the bottom end of the overlapping plate 904. A connecting column 906 is fixedly installed on the lower surface of the suspension 8.

[0059] When the connecting column 906 presses down against the overlapping plate 904, the upper space and the lower space of the extrusion plate 703 are connected to each other, so that the extrusion plate 703 can automatically feed when it moves upward and automatically extrude feed when it moves downward, thus realizing the function of automatically replenishing feed raw materials.

[0060] In this example, the position of the connecting column 906 corresponds to the position of the feed inlet 901. The diameter of the connecting column 906 is smaller than the inner diameter of the feed inlet 901. The upper part of the pressing block 905 is conical in shape. The pressing block 905 forms a telescopic structure with the extrusion plate 703, the connecting column 906, and the side plate 902. The telescopic structure on the device allows the connecting column 906 to move closer to the feed inlet 901 when the extrusion plate 703 moves upward. The purpose of the connecting column 906 being smaller than the inner diameter of the feed inlet 901 is to ensure that the feed can be conveyed downward normally when the pressing block 905 is opened.

[0061] In this example, a folding plate 13 is fixedly provided on the surface of the second top cylinder 11, and a bolt 14 is installed in the internal thread of the folding plate 13. The second top cylinder 11 and the inner cylinder 12 form a pressing structure with the first top cylinder 10 and the outer cylinder 5 through the folding plate 13 and the bolt 14. The pressing structure on the device allows the overlapping area of ​​the through holes on the inner cylinder 12 and the outer cylinder 5 to be adjusted and fixed, thereby changing the feed particle size during pelleting.

[0062] It should be noted that this invention relates to a high-efficiency pelleting device and pelleting method for chicken feed production. First, as... Figure 1-4As shown, the base 1, column 2, and support plate 3 support the entire device, while the fixing block 4 supports the outer cylinder 5 and inner cylinder 12. First, the feed raw materials are poured into the receiving cavity composed of the extrusion disc 703, the first baffle 704, and the second baffle 705. Then, the size of the feed pellets is adjusted as needed. By rotating the first top cylinder 10 and the second top cylinder 11 and inner cylinder 12 inside the outer cylinder 5, the overlapping area of ​​the holes between the outer cylinder 5 and the inner cylinder 12 changes. After adjustment, the bolt 14 can be screwed into the first top cylinder 10, thereby pressing the first top cylinder 10 and the second top cylinder 11 together. At this time, the outer cylinder 5 and the inner cylinder 12 can remain fixed, and the overlapping area of ​​the through holes on the outer cylinder 5 and the inner cylinder 12 changes, so that the size of the discharge can be adjusted before use. The motor 601 on the cutting assembly 6 drives the connecting plate 602 and the fixing rod 701 to rotate. When the fixing rod 701 rotates, it can drive the reciprocating screw 702 to rotate. When the reciprocating screw 702 rotates, it can drive the extrusion plate 703 to move up and down on the outside of the limiting rod 706, so that the device can extrude the material, so that the device can extrude the feed through the through holes on the outer cylinder 5 and the inner cylinder 12, realizing the automatic discharge function.

[0063] like Figure 1-2 and Figure 5-7 While the extrusion disc 703 reciprocates up and down, the position of the connecting column 906 relative to the feed inlet 901 changes. The overlapping plate 904 inside the feed inlet 901 is pressed downward by the feed inlet 901, thereby compressing the spring 903 on the side plate 902. The pressure block 905 moves downward, and the inclined surface of the pressure block 905 allows the material to automatically fall into the lower layer of the extrusion disc 703, realizing the function of automatic feeding while extruding material. Since the connecting plate 602, connecting shaft 603, pusher plate 604, docking plate 605 and scraper 606 are integrated, the device can drive the connecting plate 602, connecting shaft 603, pusher plate 604, docking plate 605 and scraper 606 to rotate synchronously through the output shaft of the motor 601. The scraper 606 cuts the extruded feed into pellets, and the inclined surface of the pusher plate 604 discharges the feed pellets outward, enabling the device to achieve a high-efficiency pelleting function.

[0064] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
