Technical Field

[0001] This utility model relates to the technical field of aquaculture feed processing equipment, and in particular to a fish feed processing size screening device. Background Technology

[0002] In fish feed processing, to meet the different growth stages of fish and their requirements for feed pellet size, the finished pellets usually need to be screened to separate large pellets, qualified pellets, and fine powder. Currently, common screening equipment mostly uses vibrating screens or drum screens, which, although having a certain screening efficiency, still have many shortcomings in practical applications.

[0003] First, traditional screening devices can usually only screen within a single particle size range and cannot flexibly adjust the screening accuracy according to production needs. Second, some equipment has low screening efficiency and is prone to problems such as clogging and missed screening, which affects the continuity of production and the consistency of product quality. Third, most existing screening devices do not have automatic cleaning functions, and the screen is easily clogged by fine powder after long-term operation, resulting in a decrease in screening efficiency, high maintenance frequency, and increased labor costs.

[0004] Therefore, it is necessary to design a fish feed processing size screening device with a reasonable structure, high screening efficiency, and adjustable screening accuracy to solve the above-mentioned technical problems. Utility Model Content

It also includes a first screening frame 6, a first screen 601, a second screen 602, a fixing block 7, a guide rod 8, an elastic element 9, a second screening frame 13, and a third screen (14). The first screening frame 6 is provided inside the screening box 1. The screening frame 6 has a left-low, right-high structure. The first screening frame 6 has a first screen 601 fixedly connected to the right side inside, and a second screen 602 fixedly connected to the left side inside. The screening box 1 has fixed blocks 7 symmetrically connected to the front and rear sides inside. Each fixed block 7 has a guide rod 8 fixedly connected to it. The first screening frame 6 slides on the guide rod 8. Each guide rod 8 passes through the first screening frame 6. An elastic element 9 is connected between the fixed block 7 and the first screening frame 6, and the elastic element 9 is wrapped around the guide rod 8. The second screening frame 13 is fixedly connected to the lower part of the inner side of the screening box 1. The second screening frame 13 has a third screen 14 fixedly connected inside.

[0023] like Figure 3 As shown, it also includes a guide plate 10, a first discharge frame 11, a second discharge frame 12, and a storage drawer 1401. The guide plate 10 is connected to the middle of the inner side of the screening box 1 by screws. A second screen 602 is also provided on the left side of the guide plate 10. The first discharge frame 11 is connected to the middle of the right side of the screening box 1 by screws and is precisely aligned with the guide plate 10. The second discharge frame 12 is connected to the middle of the left side of the screening box 1 by screws and is precisely aligned with the second screen 602. The storage drawer 1401 is slidably connected to the lower front side of the screening box 1. The storage drawer 1401 has a handle on the front side.

[0024] like Figure 5 , Figure 6 and Figure 7As shown, it also includes a servo motor 15, a pulley assembly 16, a transmission belt 17, a first transmission shaft 18, a protrusion 19, a second transmission shaft 20, and a fan blade 21. The servo motor 15 is connected to the rear side of the screening box 1 by screws. The servo motor 15 is electrically connected to the controller 4. The second transmission shaft 20 is rotatably connected to the upper part of the screening box 1. The fan blade 21 is fixedly connected to the second transmission shaft 20. The pulley assembly 16 includes an upper pulley and a lower pulley. The lower pulley is fixedly connected to the output shaft of the servo motor 15. The upper pulley is connected to the second transmission shaft 20. The transmission belt 17 is wound between the upper pulley and the lower pulley. The first transmission shaft 18 is rotatably connected to the screening box 1 at a position below the second transmission shaft 20. The first transmission shaft 18 is connected to the output shaft of the servo motor 15. A protrusion 19 is fixedly connected to each end of the first transmission shaft 18, and both protrusions 19 are located at the bottom of the first screening frame 6.

[0025] When the staff uses this equipment, the fish feed to be screened is first added into the equipment through the feed frame 5 on the top right side of the screening box 1. The material then falls into the first screening frame 6, which has an inclined structure with the left side lower and the right side higher. It has three layers of screens inside: the first screen 601 has the smallest mesh size and is located on the right side, used for screening fine powder particles; the second screen 602 has the largest mesh size and is located on the left side, used for screening large particles; the third screen 14 has medium-sized mesh size and is located at the bottom of the screening box 1, used for secondary screening of particles of medium size.

[0026] During operation, the servo motor 15 drives the pulley assembly 16 to rotate, and drives the upper and lower pulleys to rotate synchronously through the transmission belt 17. The first transmission shaft 18 rotates synchronously with the output shaft of the servo motor 15. Protrusions 19 are fixed at both ends of the shaft. When the protrusions 19 rotate, they periodically push the first screening frame 6, causing it to vibrate along the guide rod 8. The elastic element 9 helps to dampen and reset the vibration, thereby enhancing the screening efficiency. At the same time, the pulley assembly 16 drives the second transmission shaft 20 to rotate, and the fan blades 21 fixed on it rotate synchronously. During operation, the fan blades generate directional airflow, which "blows" the fine particles, causing them to pass through the first screen 601 quickly, preventing blockage and increasing the screening speed.

[0027] Fine particles are carried by the airflow through the first screen 601, guided by the guide plate 10, and discharged from the first discharge frame 11; larger particles flow directly out from the second discharge frame 12; while particles of intermediate size slide into the area of ​​the guide plate 10 and enter the second screening frame 13, where they are further screened by the third screen 14 and finally fall into the storage drawer 1401 at the bottom of the screening box 1. The entire screening process is continuous and stable, and different screen sizes can be replaced to adjust the screening accuracy and meet different production needs.

[0028] In addition, a transparent observation window 3 is provided on the box door 2, allowing operators to observe the screening status in real time; the controller 4 is located on the lower front side of the box door 2, used to control the start and stop of the servo motor 15 and adjust the operating parameters; both the box door 2 and the storage drawer 1401 are equipped with handles on the front side for easy opening and maintenance.
