Technical Field

[0001] This utility model relates to the field of screening device technology, specifically a fish feed screening device. Background Technology

[0002] Fish feed screening is a crucial step in the production and use of fish feed. Its purpose is to remove impurities, broken pieces, and non-standard particles from the feed through specific equipment and methods, ensuring the uniformity, palatability, and nutritional value of the feed, thereby improving the feeding rate and growth of fish.

[0003] Depending on the requirements, the filter frame for screening fish feed needs to have a filter screen of the corresponding size. Traditional filter frames and vibrating frames are connected by welding or bolts, which is inconvenient to assemble, difficult to clean, and relatively inconvenient to use. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a fish feed screening device.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fish feed screening device, comprising a support frame, a vibrating frame, springs, mounting components, and a filter assembly. Springs are arranged at the four corners of the support frame, and the vibrating frame is positioned above the four sets of springs. The top wall of the vibrating frame is inclined. A filter assembly is mounted on the vibrating frame, comprising a filter frame, a filter screen, and a guide plate. A filter screen is mounted on the top wall of the filter frame, and a guide plate connected to the side wall of the vibrating frame is positioned below the filter frame. Mounting components connected to the guide plate are located at the front and rear ends of the vibrating frame. Each mounting component includes a handle, a worm gear, a worm, a screw, and a plug. Movable grooves are provided on the front and rear sides of the vibrating frame, and a worm and a worm gear are located within these grooves. The worm meshes with the worm gear. Screws are symmetrically arranged on the left and right sides of the worm gear. Auxiliary grooves are also provided on the left and right sides of the vibrating frame, and plugs are located within these auxiliary grooves. The screws pass through the auxiliary grooves and are threadedly connected to the plugs. A slot adapted to the plugs is provided on the guide plate.

[0008] To ensure the stability of the connection between the guide plate and the vibration frame, the present invention is improved by providing guide grooves on the left and right sides of the vibration frame that are adapted to the guide plate, and the auxiliary grooves passing through the guide grooves.

[0009] Preferably, the handle is provided with a friction block.

[0010] Preferably, the inner wall of the support frame is provided with a guide ramp.

[0011] Preferably, a material guide frame is also provided near the lower end of the filter frame of the support frame.

[0012] Preferably, the insert is rectangular, and a reinforcing rib connected to the guide plate is provided below the filter frame.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a fish feed screening device, which has the following beneficial effects:

[0015] In this fish feed screening device, rotating the handle with friction blocks drives the worm gear to rotate, which in turn meshes with the worm wheel, causing the screws on both sides to rotate synchronously. This allows the insert block to extend along the auxiliary groove and insert into the slot of the guide plate, achieving quick locking between the filter frame and the vibrating frame. Reversing the rotation of the handle retracts the insert block, releasing the lock. Compared to traditional welding or bolted connections, this structure allows for tool-free assembly and disassembly of the filter components, facilitating cleaning of the filter frame.

[0021] 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.

[0022] Please see Figures 1-4A fish feed screening device includes a support frame 1, a vibrating frame 2, springs 3, mounting components, and a filter assembly. Springs 3 are located at the four corners of the support frame 1, and the vibrating frame 2 is positioned above the four sets of springs 3. The top wall of the vibrating frame 2 is inclined. A filter assembly is mounted on the vibrating frame 2. The filter assembly includes a filter frame 4, a filter screen 5, and a guide plate 6. The filter screen 5 is located on the top wall of the filter frame 4, and the guide plate 6, which connects to the side wall of the vibrating frame 2, is located below the filter frame 4. The front and rear ends of the vibrating frame 2 are connected to the guide plate. The mounting components for connection 6 include a handle 7, a worm gear 8, a worm 9, a screw 10, and a plug 11. Movable grooves are provided on the front and rear sides of the vibration frame 2, and the worm 9 and worm gear 8 are disposed within these grooves. The worm 9 meshes with the worm gear 8. Screws 10 are symmetrically arranged on the left and right sides of the worm gear 8. Auxiliary grooves are also provided on the left and right sides of the vibration frame 2, and plugs 11 are disposed within these auxiliary grooves. The screws 10 pass through the auxiliary grooves and are threadedly connected to the plugs 11. A slot adapted to the plug 11 is provided on the guide plate 6.

[0023] In actual use, the vibrating frame 2 is powered by the springs 3 of the support frame 1. The vibrating frame 2 can drive the filter assembly to vibrate under the support of the springs 3 of the support frame 1, and screen the material on the filter assembly. The springs 3 at the four corners of the support frame 1 elastically support the vibrating frame 2. When driven by an external vibration source (such as a vibrating motor, conventional configuration), the vibrating frame 2 generates high-frequency vibration under the action of the springs 3. Since the top wall of the vibrating frame 2 is inclined, the fish feed slides down the inclined direction under the action of vibration. At the same time, under the dual action of gravity and vibration, feed particles that meet the specifications fall into the support frame 1 through the filter screen 5 at the top of the filter frame 4, while impurities, broken materials and oversized particles slide down the inclined surface to the bottom of the filter frame 4, realizing automatic grading and screening.

[0024] The guide ramp 14 on the inner wall of the support frame 1 guides the qualified feed after screening to the bottom to avoid residue; the feed guide frame 15 near the bottom of the filter frame 4 accurately collects impurities and excessive particles to prevent them from scattering and ensure that the screening process is orderly and efficient.

[0025] Rotating the handle 7 with friction block 13 drives the worm 9 in the movable groove of the vibrating frame 2 to rotate. The worm 9 meshes with the worm wheel 8, causing the worm wheel 8 to rotate, which in turn causes the screws 10 on both sides of the worm wheel 8 to rotate synchronously. Since the insert 11 is threadedly connected to the screw 10 and is restricted by the auxiliary groove (cannot rotate), the rotation of the screw 10 will push the insert 11 to extend along the auxiliary groove and insert into the slot of the guide plate 6. At the same time, the guide plate 6 is embedded in the guide groove 12 of the vibrating frame 2, and with the rigid connection between the rectangular insert 11 and the slot, a stable lock is achieved between the filter frame 4 and the vibrating frame 2, ensuring that it does not loosen during vibration screening.

[0026] Reverse rotation of handle 7 causes worm 9 to drive worm wheel 8 and screw 10 to rotate in the opposite direction, and insert block 11 retracts along the auxiliary groove, disengaging from the slot of guide plate 6 and unlocking. At this time, the filter assembly (filter frame 4 + guide plate 6) can be directly pulled out from the guide groove 12 of vibrating frame 2 to complete disassembly, facilitating cleaning of filter screen 5 or replacement of filter frame 4 with different specifications (such as replacing filter screen 5 with one of corresponding mesh size to adapt to different feed pellets);

[0027] The reinforcing rib 16 below the filter frame 4 enhances the connection strength between the guide plate 6 and the filter frame 4, avoids structural deformation caused by long-term vibration, and extends service life.

[0028] The vibrating frame 2 has guide grooves 12 on both the left and right sides that are compatible with the guide plate 6. The auxiliary groove passes through the guide groove 12. The guide groove 12 restricts the lateral displacement of the guide plate 6, and the auxiliary groove ensures that the insertion block 11 moves in a straight line. The two work together to ensure the precise docking of the insertion block 11 with the slot and improve the locking reliability.
