[0002] Crayfish meat is delicious and rich in protein and nutrients, making it an ideal raw material for food processing. As a delicious aquatic food, it has become increasingly popular in China in recent years. With the development of the crayfish industry, processing has become an important link. Proper processing methods can preserve the delicious taste and nutritional value of crayfish, while also ensuring food safety and hygiene.

[0003] However, existing screening devices for crayfish use weight-based screening, which can only screen individual crayfish one by one. This results in slow processing when screening batches of crayfish, thus affecting processing efficiency. Therefore, we propose a weight-based screening device for crayfish processing. Utility Model Content

[0004] To address the issue that existing devices for sorting crayfish in batches are slow due to the individual sorting method, which affects the processing efficiency of crayfish, this invention provides a weight sorting device for crayfish processing. This device can sort crayfish of different weights in batches, improving processing efficiency and solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A weight screening device for crayfish processing includes an operating table, a conveyor belt rotatably connected to the top of the operating table, protective side plates symmetrically connected to the top of the operating table, and multiple screening rollers rotatably connected between the two protective side plates. The ends of the screening rollers are connected to a drive mechanism, and the vertical distance between the multiple screening rollers and the top of the conveyor belt decreases sequentially. A support frame is connected to the top of the operating table, and a push plate is set between the two protective side plates. The top of the push plate is connected to the support frame through a sliding mechanism, and multiple openings are opened on the push plate, through which the screening rollers pass. Multiple discharge ports are set on one of the protective side plates, and a discharge plate is connected to the discharge port. The discharge plate is located between adjacent screening rollers.

[0006] Optionally, the drive mechanism includes a first motor, multiple screening rollers are rotatably connected to a first rotating shaft and a protective side plate, multiple sprockets are coaxially connected to one end of the first rotating shaft, adjacent sprockets are connected by a chain, and the first motor is connected to one end of the first rotating shaft.

[0007] Optionally, bristles are attached to the outer wall of the screening roller.

[0008] Optionally, the sliding mechanism includes a second motor, a screw connected to the top of the support frame via a bearing seat, the second motor and one end of the screw being fixedly connected, a mounting seat being threaded onto the screw, and an electric telescopic rod being vertically connected between the bottom of the mounting seat and the top of the push plate.

[0009] Optionally, a second slide groove is provided on the support frame, and a slider that slides into and slides into the second slide groove is connected to the bottom of the mounting base.

[0010] Optionally, a first slide groove is provided on the support frame, and a guide rod is vertically connected to the top of the push plate, with the upper end of the guide rod slidably connected to the first slide groove.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figures 1 to 4 This utility model provides a technical solution: a weight screening device for crayfish processing, including an operating table 18, a conveyor belt 16 rotatably connected to the top of the operating table 18, multiple rotating rollers 23 connected to the operating table 18 via a second rotating shaft 24, the conveyor belt 16 connected to the rotating rollers 23, and a third motor 22 fixedly connected to the second rotating shaft 24 at one end. Figure 2 , 3 As shown, driven by the third motor 22, the rotating roller 23 is rotated, which enables the conveyor belt 16 to rotate and transport the crayfish located on top of it. An extension plate 1 is symmetrically connected to the top of the operating table 18. One end of the extension plate 1 extends to the top of the conveyor belt 16, which can prevent the crayfish from falling through the gaps and ensure the normal transportation of the crayfish.

[0022] like Figure 2 , 3 As shown, protective side plates 2 are symmetrically connected to the top of the operating table 18. Multiple screening rollers 15 are rotatably connected between the two protective side plates 2. The vertical distance between the multiple screening rollers 15 and the top of the conveyor belt 16 decreases sequentially. With the rotation of the screening rollers 15, the crayfish that can pass between the screening rollers 15 and the conveyor belt 16 can be moved. By decreasing the vertical distance, crayfish of different sizes can be screened separately, thereby achieving the screening of crayfish of different weights. In order to avoid excessive pressure on the crayfish when the screening rollers 15 rotate, brush bristles are connected to the outer wall of the screening rollers 15, which can protect the crayfish while screening, thus ensuring the integrity of the crayfish after screening.

[0023] In actual use, the end of the screening roller 15 is connected to the drive mechanism. The drive mechanism includes a first motor 4. Multiple screening rollers 15 are rotatably connected to the first rotating shaft 21 and the protective side plate 2. Multiple sprockets 20 are coaxially connected to one end of the first rotating shaft 21. Adjacent sprockets 20 are connected by chains. The first motor 4 is connected to the end of one of the first rotating shafts 21.

[0024] like Figure 1 , 2 As shown in Figure 4, a support frame 3 is connected to the top of the operating table 18, and a push plate 9 is set between the two protective side plates 2. The top of the push plate 9 is connected to the support frame 3 through a sliding mechanism. The sliding mechanism includes a second motor 13. The top of the support frame 3 is connected to a screw 12 through a bearing seat 14. The second motor 13 and one end of the screw 12 are fixedly connected. A mounting seat 7 is threaded onto the screw 12. An electric telescopic rod 17 is vertically connected between the bottom of the mounting seat 7 and the top of the push plate 9. The push plate 9 has multiple openings 8, and the screening roller 15 passes through the openings 8. Multiple discharge ports 25 are set on one of the protective side plates 2, and a discharge plate 19 is connected to the discharge port 25. The discharge plate 19 is located between adjacent screening rollers 15.

[0025] In summary, when using this weight screening device for crayfish processing, the crayfish to be processed are placed on top of the conveyor belt 16 and moved under the drive of the conveyor belt 16 and screened by the screening rollers 15. After screening, the crayfish are located between adjacent screening rollers 15. The second motor 13 is controlled to drive the screw 12 to rotate, which in turn drives the mounting base 7 to slide horizontally on the screw 12. At this time, the push plate 9 can push the screened crayfish to the opening 8. The crayfish fall from the opening 8 onto the discharge plate 19 and are discharged. After the discharge is completed, the electric telescopic rod 17 is controlled to drive the push plate 9 to move up and slide back to the initial position, so that the cyclic discharge operation can be performed.

[0026] like Figure 4 As shown, in order to achieve stable sliding and lifting adjustment of the push plate 9, a second slide groove 11 is provided on the support frame 3, and a slider 10 that is slidably connected to the second slide groove 11 is connected to the bottom of the mounting base 7. A first slide groove 5 is provided on the support frame 3, and a guide rod 6 is vertically connected to the top of the push plate 9. The upper end of the guide rod 6 is slidably connected to the first slide groove 5.
