Description

Technical Field

[0001] This utility model relates to the field of feed screening technology, specifically a crab feed screening device based on vibration automatic flow. Background Technology

[0002] Crab feed refers to various feeds used to feed crabs, including natural bait and artificial compound feed. The type and selection of crab feed depend on the growth stage of the crabs and the purpose of farming. A sieving device is needed during the feeding process to improve the purity of the crab feed.

[0003] According to the announcement number CN209238393U, a crab feed sieving device based on vibration automatic flow is proposed. Its structure includes a feeding structure, a sieving equipment shell, a vibrator transmission device, a powder recovery hopper, and a feed sieving device. The crab feed sieving device, through the cooperation of the feeding structure and the feed sieving device, allows the feed to be evenly distributed and fall onto the surface of the feed screen after being poured into the feeding hopper. This prevents the feed from piling up and entering the screen, while removing the powder adhering to the feed surface, improving the purity of the feed. The powder removal device can also remove the powder clogging the screen surface in a timely manner during the sieving process, preventing the screen from becoming clogged when the feed contains a lot of powder, and ensuring the normal operation of the screen.

[0004] As described above, existing crab feed screening devices use vibration equipment to provide vibration to the screening device, thereby enabling the screening of crab feed. However, during the vibration screening process, clumped feed cannot be fed, leading to blockage of the screening device. This not only reduces the purity of the crab feed screened by the screening device but also reduces the working efficiency of the screening device. In order to solve the above problems, a crab feed screening device based on vibration automatic flow control is proposed. Utility Model Content

[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] This utility model provides, for example Figures 1-4The illustrated crab feed sieving device based on vibration automatic flow includes a support frame 1 and a filter screen 2. Fixed plates 3 are fixedly connected to the symmetrical side walls of the filter screen 2. An adjustment mechanism 4 is installed on the fixed plates 3, with its bottom fixed to the top of the support frame 1. Vibrators 5 are installed at both ends of the side walls of the filter screen 2, positioned above the fixed plates 3. Support seats 6 are fixedly connected to both ends of the filter screen 2, and loosening mechanisms 7 are installed on the support seats 6 to cooperate with the filter screen 2. The vibrators 5 provide vibration to the filter screen 2, thus sieving the feed within the filter screen 2 during vibration. The adjustment mechanism 4 works in conjunction with the vibrators 5 to provide limiting support between the filter screen 2 and the support frame 1 without affecting the vibration of the filter screen 2. The loosening mechanism 7 on the filter screen 2 loosens clumps and agglomerates of feed, allowing for rapid feeding and sieving, thus enhancing the working efficiency of the crab feed sieving device.

[0023] The adjustment mechanism 4 includes a movable part 41, which is installed at both ends of the lower surface of the fixed plate 3. The bottom end of the movable part 41 is installed on the top of the support frame 1. A movable sleeve 42 is embedded in a symmetrical position on the fixed plate 3. A positioning rod 43 is movably connected to the inner cavity of the movable sleeve 42. The lower end of the positioning rod 43 is fixedly connected to the top of the support frame 1. A spring 44 is sleeved on the surface of the positioning rod 43. The two ends of the spring 44 are fixedly connected to the opposite side of the fixed plate 3 and the support frame 1, respectively. Through the cooperation of the movable part 41, the positioning rod 43 and the spring 44, the vibrating filter screen 2 can be provided with a movable support effect, so that the filter screen 2 has a certain buffer space adjustment when vibrating, thereby enhancing the vibration amplitude of the filter screen 2 and improving the screening effect of feed.

[0024] The loosening mechanism 7 includes a stepper motor 71, which is mounted on one of the support seats 6. The output shaft of the stepper motor 71 is connected to a bidirectional lead screw 72. One end of the bidirectional lead screw 72 is rotatably connected to the surface of the other support seat 6. Moving blocks 73 are provided at both ends of the surface of the bidirectional lead screw 72 through threaded sleeves. A fixed rod 74 is fixedly connected to the lower surface of the moving block 73. Multiple loosening rods 75 are fixedly connected at equal intervals on the fixed rod 74. The multiple loosening rods 75 are located in the inner cavity of the filter screen 2. The stepper motor 71 provides driving force, thereby driving the moving blocks 73 on the bidirectional lead screw 72 to move. Therefore, the moving blocks 73 and the loosening rods 75 on the fixed rod 74 move back and forth in the filter screen 2, thereby loosening and cleaning the agglomerated and accumulated feed, enhancing the working efficiency of the filter screen 2 in screening feed, and reducing the clogging of the filter screen 2 during the screening process.

[0025] The lower surfaces of both ends of the fixed rod 74 are fixedly connected to the limiting sleeves 8, and the inner cavity of the limiting sleeves 8 is slidably connected to the limiting rods 9. The two ends of the limiting rods 9 are fixed to the filter screen 2 by the fixing blocks. The matching of the limiting sleeves 8 and the limiting rods 9 can provide stability for the movement of the fixed rod 74, so that the fixed rod 74 can drive the loosening rod 75 to loosen the clumps and piles of feed, thereby allowing the feed to be quickly screened and discharged under the vibration of the filter screen 2.

[0026] A collection box 10 is placed in the cavity at the bottom of the support frame 1. The collection box 10 is located directly below the filter screen 2. The screened feed can be collected through the collection box 10.

[0027] The outer wall of the collection box 10 is fitted with a limiting strip 11. The bottom of the limiting strip 11 is fixed on the support frame 1, which can provide a limiting effect on the placement of the collection box 10, and prevent the collection box 10 from shifting when it is placed, thus affecting the collection of feed.

[0028] The top of the positioning rod 43 is fixedly connected to the limiting block 12. The cross-sectional area of ​​the limiting block 12 is larger than that of the positioning rod 43, which prevents the filter screen 2 from being installed on the positioning rod 43 through the fixing plate 3. Therefore, the filter screen 2 will not easily detach from the positioning rod 43 when the vibration amplitude is too large.

[0029] In practical use, the feed to be screened is first placed on the filter screen 2, and then the collection box 10 is placed below the filter screen 2. The vibrator 5 is then activated, providing vibration to the filter screen 2. During the vibration of the filter screen 2, the movable part 41, the positioning rod 43, and the spring 44 work together to provide support for the vibrating filter screen 2, allowing for some buffer space adjustment during vibration. This enhances the vibration amplitude of the filter screen 2 and improves the screening effect on the feed. Simultaneously, the stepper motor 71 provides driving force, which moves the moving block 73 on the bidirectional lead screw 72. Therefore, the loosening rod 75 on the moving fixed rod 74 moves back and forth within the filter screen 2, loosening and cleaning clumps and accumulated feed, improving the efficiency of the filter screen 2 in screening feed, and reducing the likelihood of clogging during the screening process.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
