Abstract
Description
Technical Field
[0001] This utility model relates to the field of feed processing machinery technology, and in particular to a corn feed puffing device. Background Technology
[0002] In the feed processing industry, extrusion technology is an important process for improving the nutritional value, palatability, and shelf life of feed. Corn, as a major energy feed source, undergoes extrusion processing, which increases the gelatinization of its starch, making it easier for animals to digest and absorb.
[0003] In the traditional extruded feed production process, the extruded material often affects the quality of the final product due to uneven particle size. Some equipment uses fixed screens for screening, but due to the lack of effective vibration or shaking mechanisms, the screening efficiency is low, which can easily lead to screen blockage and affect continuous production. In addition, some vibrating screening devices have complex structures, high energy consumption, and are prone to mechanical wear after long-term operation, which can reduce the screening effect and make it difficult to ensure the uniformity of feed particle size. This not only reduces the overall quality of the feed, but also easily leads to raw material waste and increased production costs due to the mixing of unqualified particles. Utility Model Content

[0022] 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.
[0023] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a corn feed puffing device, comprising a housing 1, a mounting plate 12 fixedly connected to the left side of the housing 1, a second motor 13 fixedly connected to the left side of the mounting plate 12, a circular plate 14 fixedly connected to the output end of the second motor 13, a movable rod 15 fixedly connected to the right side of the circular plate 14, a movable plate 16 slidably connected to the outside of the movable rod 15, positioning rods 17 fixedly connected to both sides of the right side of the mounting plate 12, the movable plate 16 slidably connected to the outside of the two positioning rods 17, connecting plates 18 fixedly connected to both sides of the movable plate 16, and limiting components fixedly connected to the opposite sides of the two connecting plates 18 for limiting the movable plate 16; and one end of a crossbar 23 fixedly connected to both sides of the right side of the two connecting plates 18. The other end of each crossbar 23 is fixedly connected to a screen frame 24, which is slidably connected inside the housing 1. The limiting component includes a slider 19 and a slide rod 20. Multiple sliders 19 are fixedly connected to the opposite side of the two connecting plates 18. Multiple sliders 19 are slidably connected to the outside of the slide rod 20. Positioning frames 21 are fixedly connected to both sides of the right side of the mounting plate 12. Two slide rods 20 are fixedly connected inside the positioning frames 21. Buffer springs 22 are sleeved on both sides of the outside of the two slide rods 20. One end of multiple buffer springs 22 is fixedly connected to the inside of the positioning frames 21. The other end of multiple buffer springs 22 is fixedly connected to the opposite side of the multiple sliders 19. A discharge hopper 11 is fixedly connected to the right side of the housing 1. Multiple crossbars 23 are slidably connected inside the housing 1.
[0024] When feed enters the housing 1, it first falls into the screen frame 24. The screen frame 24 is designed to allow feed particles to roll and slide freely within the frame, preparing for screening. Then, motor 13 is started; its output end is connected to a circular plate 14. Motor 13 drives the circular plate 14 to rotate, which in turn drives the movable rod 15 to rotate. The movable rod 15 can rotate under external force, thereby driving the connected movable plate 16. Driven by the movable rod 15, the movable plate 16 slides along the outside of the positioning rod 17. The sliding of the moving plate 16 further drives the two connecting plates 18 to move up and down. The vertical movement of the connecting plates 18 causes the slider 19 to slide along the sliding rod 20. During this process, the buffer spring 22 absorbs and buffers the impact force to prevent damage to the device caused by the rapid movement of the connecting plates 18. As the connecting plates 18 move, multiple crossbars 23 slide inside the box 1. The design of these crossbars 23 allows the screen frame 24 to shake up and down accordingly. Finally, the qualified feed after screening is discharged through the discharge hopper 11, completing the entire screening process.
[0025] Reference Figure 1 and Figure 2A fixed base 2 is fixedly connected to the upper part of the box body 1. A tank body 3 is fixedly connected inside the fixed base 2. A motor 4 is fixedly connected to the left side of the fixed base 2. A rotating shaft 5 is fixedly connected to the output end of the motor 4. Mounting rings 6 are fixedly connected to the outer periphery of the rotating shaft 5. Stirring rods 7 are fixedly connected to both sides of the outer periphery of the multiple mounting rings 6. The multiple stirring rods 7 are rotatably connected to the inside of the tank body 3. A cover 8 is provided on the upper part of the tank body 3. One end of a connecting pipe 9 is fixedly connected to the bottom of the tank body 3. The other end of the connecting pipe 9 is fixedly connected to the upper part of the box body 1. Support seats 10 are fixedly connected to both sides of the upper part of the box body 1. The tank body 3 is located inside the support seats 10.
[0026] The lid 8 is located on top of the tank 3, ensuring that the feed can enter the tank 3 conveniently and cleanly. The inside of the tank 3 maintains a high-temperature environment. Under the action of high temperature, the starch and protein in the feed undergo structural changes, making it more crisp and palatable. In order to ensure that the feed is heated evenly during the extrusion process, the motor 4 is started. When the motor 4 starts, the rotating shaft 5 begins to rotate. The mounting ring 6 is fixed on the rotating shaft 5 and rotates with the rotating shaft 5. Each mounting ring 6 is equipped with multiple stirring rods 7. The stirring rods 7 rotate inside the tank 3 to stir the feed. After extrusion, the feed is discharged through the connecting pipe 9 and enters the box 1. The connecting pipe 9 ensures the smooth output of the feed, while the box 1 provides a space for collecting and storing the extruded feed.
[0027] Working principle: First, corn feed is added into the tank 3 through the lid 8. Under the high temperature inside the tank 3, it is expanded. At the same time, motor 4 is started. The output of motor 4 drives the rotating shaft 5 to rotate. The rotation of the rotating shaft 5 drives the mounting rings 6 to rotate. Multiple mounting rings 6 drive multiple stirring rods 7 to rotate inside the tank 3, stirring the feed. Finally, the expanded feed is discharged through the connecting pipe 9 and enters the box 1. This achieves effective stirring, which can make the feed evenly distributed in the tank 3, ensuring that all particles receive the same heat treatment and pressure, improving the uniformity and consistency of the expanded product. After the feed enters the box 1, it falls into the screen frame 24. Motor 13 is started. The output of motor 13 drives the circular plate 1. 4. Rotation: The rotation of the circular plate 14 drives the rotation of the movable rod 15. When the movable rod 15 rotates, it drives the movable plate 16 to slide outside the movable rod 15. When the movable plate 16 slides, it slides outside the positioning rod 17. Under the action of the movable rod 15, the movable plate 16 drives the two connecting plates 18 to move up and down. When the connecting plates 18 move, they drive the slider 19 to slide along the sliding rod 20 and repeatedly squeeze the buffer spring 22. When the connecting plates 18 move, they drive multiple crossbars 23 to slide inside the box 1, thereby driving the screen frame 24 to shake up and down inside the box 1 to screen the feed. After screening, qualified feed is discharged through the discharge hopper 11, which realizes effective screening, ensures uniform feed particle size, improves the overall quality of feed, and reduces feed waste.
