Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of screening devices, and in particular relates to a screening device for fish feed pellets. Background Technology
[0002] With the large-scale development of modern aquaculture, fish feed, as a key production factor to ensure the growth efficiency and survival rate of fish, has increasingly higher requirements for quality control. In the process of fish feed production, the uniformity of feed pellet size directly affects the feeding efficiency and nutrient absorption of fish. Therefore, an efficient fish feed pellet screening device is needed to screen the finished pellets.
[0003] However, existing fish feed pellet screening devices are not easy to adjust the vibration intensity during use. It is difficult to adjust the screening force according to the size and hardness of fish feed pellets. Excessive vibration may cause pellet damage, while insufficient vibration may lead to incomplete screening. Utility Model Content
[0004] The purpose of this invention is to provide a device for screening fish feed pellets. By setting an adjustment part, it solves the problems of existing fish feed pellet screening devices, which are inconvenient to adjust the vibration intensity during use, are difficult to adjust the screening force according to different sizes and hardness of fish feed pellets, and cause pellet damage due to excessive vibration or incomplete screening due to insufficient vibration.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a screening device for fish feed pellets, comprising a support frame and a screen slidably connected to the inner wall of the support frame, wherein a discharge hopper is connected to the support frame, and further comprising: an adjustment part disposed on the support frame; and an oscillation part disposed on the screen; wherein the adjustment part is located above the oscillation part, and the screen slides only within a very small range on the support frame.
[0007] Furthermore, the adjustment unit includes a power assembly mounted on the top of the support frame, the power assembly including a turntable disposed on the support frame; and an adjustment assembly disposed on the turntable, wherein a rectangular mounting groove is provided on the front side of the turntable, and the adjustment assembly is installed in the rectangular mounting groove.
[0008] Furthermore, the oscillation unit includes a rotating assembly mounted on the right inner wall of the support frame; and an oscillation assembly disposed on the top of the screen; wherein the oscillation assembly is disposed directly below the rotating assembly.
[0009] Furthermore, the power assembly includes a motor fixedly connected to the right side of the support frame, and the output shaft of the motor is fixedly connected to a rotating shaft via a coupling; wherein, the rotating shaft rotates through the support frame, passes through a turntable and is fixedly connected to it, and the rotation of the turntable transmits the motion trajectory through an adjustment component, thereby achieving the basis for regulating the oscillation intensity.
[0010] Furthermore, the adjustment component includes a bracket fixedly connected to the turntable. Two sliding rods are fixedly connected to the inner wall of the bracket, and sliders are slidably connected to the outer walls of the two brackets. A fastening element is provided on the bracket. The bracket is fixedly connected within a rectangular mounting slot of the turntable. The fastening element includes a locking block located on the right side of the slider. Several limiting slots are formed on the inner wall of the bracket. Several spring-loaded telescopic rods are fixedly connected between the slider and the locking block. The right side of the locking block extends into and abuts against the corresponding limiting slot. By adjusting the position of the slider on the sliding rod, the eccentricity of the turntable during rotation is changed, thereby adjusting the movement amplitude of the oscillating block. The fastening element fixes the slider position, ensuring that the oscillation intensity remains stable during the screening process, achieving dynamic adaptation to different particle sizes, and improving screening flexibility and accuracy.
[0011] Furthermore, the rotating assembly includes a hinged rod hinged to the left side of the slider, a second slide rod hinged to the bottom of the hinged rod, a fixed block slidably connected to the outer wall of the second slide rod, and an oscillating block fixedly connected to the bottom of the second slide rod; wherein, the right side of the fixed block is fixedly connected to the right inner wall of the support frame, converting the power transmitted by the adjustment part into the up-and-down reciprocating motion of the oscillating block; the fixed block provides sliding support to ensure stable motion trajectory and provides continuous mechanical driving force for the oscillating assembly.
[0012] Furthermore, the oscillation assembly includes an oscillation box fixedly connected to the top of the screen. A second spring telescopic rod is fixedly connected to the bottom inner wall of the oscillation box, and a rectangular slider is fixedly connected to the top of the second spring telescopic rod. An oscillation block is fixedly connected to the top of the rectangular slider. The outer wall of the rectangular slider is slidably connected to the inner wall of the oscillation box, and the top of the oscillation block extends slidably to the outside of the oscillation box. The oscillation block is positioned directly below the first oscillation block. The first oscillation block presses against the second oscillation block. Through the sliding of the rectangular slider within the oscillation box and the elastic action of the spring telescopic rod, the mechanical motion is converted into high-frequency oscillation of the screen. The spring telescopic rod buffers the impact force, stabilizes the oscillation frequency, avoids equipment wear, and simultaneously promotes particle jumping on the screen, preventing clogging of the screen holes and improving screening efficiency and particle separation accuracy.
[0013] This utility model has the following beneficial effects:
[0014] 1. By setting the adjustment section, when adjusting the oscillation intensity, pull the locking block to the right to move it to the right and compress several spring telescopic rods until the locking block separates from the corresponding limiting groove. At this time, the locking block's limit on the slider is released. Slide the slider forward to the corresponding position and then release the locking block. Several spring telescopic rods will drive the locking block to reset and lock it back into the corresponding limiting groove. During this process, the slider will deviate from the center of the turntable, causing the lowest drop point of the oscillating block to move down, thereby increasing the oscillation intensity. Conversely, sliding the slider backward to bring it closer to the center of the turntable can reduce the oscillation intensity. The oscillation intensity can be changed, thereby adjusting the screening force for fish feed pellets of different sizes and hardness, avoiding pellet damage due to excessive oscillation or incomplete screening due to insufficient oscillation, thus enhancing the adaptability of the device to different production scenarios.
[0015] 2. After the oscillation section and adjustment section are adjusted, the motor is turned on. The motor drives the turntable to rotate through the shaft. The turntable drives the hinge rod to move through the adjustment component, thereby driving the slide bar two to move up and down reciprocally. The oscillation block one on it moves up and down reciprocally accordingly. During the descent of the oscillation block one, it will squeeze the oscillation block two, causing it to descend and compress the spring telescopic rod two, until the oscillation block one rises and separates from the oscillation block two. The spring telescopic rod two rebounds and drives the rectangular slider to collide with the oscillation box. Due to the impact, the rectangular slider will descend due to the reaction force and compress the spring telescopic rod two. This process continues until the kinetic energy is exhausted, thereby generating oscillation on the screen through the oscillation box. The oscillation can make the particles on the screen move continuously, preventing large particles from blocking the screen holes or small particles from accumulating, thus ensuring a smooth screening process.

[0028] The oscillation unit 3 includes a rotating assembly 31, which is mounted on the inner right side wall of the support frame 111; and an oscillation assembly 32, which is disposed on top of the screen 112. The oscillation assembly 32 is positioned directly below the rotating assembly 31. The rotating assembly 31 includes a hinge rod 311 hinged to the left side of the slider 223. A second slide rod 312 is hinged to the bottom of the hinge rod 311. A fixing block 313 is slidably connected to the outer wall of the second slide rod 312. An oscillation block 314 is fixedly connected to the bottom of the second slide rod 312. The right side of the fixing block 313 is fixedly connected to the inner right side wall of the support frame 111. The oscillation assembly 32 includes components fixedly connected to... The oscillating box 321 is located at the top of the screen 112. A spring telescopic rod 322 is fixedly connected to the bottom inner wall of the oscillating box 321. A rectangular slider 323 is fixedly connected to the top of the spring telescopic rod 322. An oscillating block 324 is fixedly connected to the top of the rectangular slider 323.

By setting the oscillating part 3, the particles on the screen 112 can be continuously moved by oscillation, preventing large particles from blocking the screen holes or small particles from accumulating, thereby ensuring a smooth screening process.
[0029] A specific application of this embodiment is as follows: When adjusting the oscillation intensity, pull the locking block 224 to the right to compress several spring telescopic rods 226 until the locking block 224 separates from the corresponding limiting groove 225. At this time, the limiting of the slider 223 by the locking block 224 is released. Slide the slider 223 forward to the corresponding position, and then release the locking block 224. The several spring telescopic rods 226 drive the locking block 224 to reset and re-lock onto the corresponding limiting groove 225. During this process, the slider 223 will deviate from the center of the turntable 213, causing the lowest landing point of the oscillating block 314 to move down, thereby increasing the oscillation intensity. Conversely, sliding the slider 223 backward to bring it closer to the center of the turntable 213 can reduce the oscillation intensity. After the adjustment part 2 has finished adjusting, turn on the motor 211. The motor 211 drives the rotating shaft 212. Turntable 213 rotates, and turntable 213 drives hinge rod 311 to move through adjustment component 22, thereby driving slide bar 2 312 to move up and down reciprocally. Vibrating block 1 314 on it moves up and down reciprocally accordingly. During the descent of vibrating block 1 314, it will squeeze vibrating block 2 324, causing it to descend and compress spring telescopic rod 2 322, until vibrating block 1 314 rises and separates from vibrating block 2 324. Spring telescopic rod 2 322 rebounds and drives rectangular slider 323 to collide with vibrating box 321. Due to the impact of rectangular slider 323, it will descend and compress spring telescopic rod 2 322 due to reaction force. This process continues until the kinetic energy is exhausted, thereby generating vibration on screen 112 through vibrating box 321. When raw materials are placed on screen 112 in support frame 111, screening begins. Those that pass screening are discharged from discharge hopper 113.
