By setting up the sweeping structure 7 and utilizing the sweeping method, it is convenient to sweep away the crayfish trapped on the inner side of the screen frame 3, and can realize the simple sweeping and brushing cleaning of the surface of the crayfish, which improves the performance of the sorting equipment to a certain extent. By setting up the combing structure 8, it is not only convenient to scrape off the crayfish clamped by the brush bristles 711, but also convenient to comb the brush bristles 711, which further improves the performance of the sorting equipment. By setting up the supporting structure 9, it is convenient to stably support the bag opening of the packaging bag below the first discharging frame 4 and the second discharging frame 5, which facilitates the subsequent bagging of the crayfish and further improves the performance of the sorting equipment.
[0031] The specific configuration and functions of the sweeping structure 7, the combing structure 8 and the supporting structure 9 will be described in detail below.
[0032] like Figure 1-4As shown, the sweeping mechanism 7 includes a guide rail frame 701 fixedly connected to the side wall of the fixed frame 2. The side wall of the guide rail frame 701 is slidably connected to a mounting plate 705. A second motor 706 is fixedly installed inside the mounting plate 705. Both sides of the screen frame 3 are provided with reserved holes 708 in a strip structure. The output end of the second motor 706 is fixedly mounted with a rotating shaft 710. The side wall of the rotating shaft 710 is fixedly connected to a brush roller 707. The side wall of the brush roller 707 is fixedly connected to three groups of bristles 711. The three groups of bristles 711 are arranged in a circular array on the side wall of the brush roller 707. When the claws or body of the crayfish rests on the screen frame 3 and cannot fall off on its own, the second motor 706 on the mounting plate 705 drives the brush roller 707 to rotate. The bristles 711 are of an arc-shaped structure. By providing the bristles 711 with an arc structure, the side wall of the arc-shaped bristles 711 can be used to sweep the stuck crayfish into the fixed frame 2 through a flexible sweeping motion. A mounting rod 709 is fixedly mounted on the side wall of the fixed frame 2. The other end of the mounting rod 709 is fixedly connected to the mounting ring 702. A first motor 703 is fixedly mounted inside the mounting ring 702. A screw rod 704 is fixedly mounted on the output end of the first motor 703. The screw rod 704 is threadedly connected to the inner surface of the mounting plate 705. When the first motor 703 is activated, the screw rod 704 rotates, driving the mounting plate 705 to move horizontally back and forth along the guide rail frame 701.
[0033] like Figure 1-2 and Figure 4 As shown, the upper surface of the mounting plate 705 has a combing structure 8, which includes a connecting block 82 fixedly connected to the upper end of the mounting plate 705. The connecting block 82 is internally slidably connected to a limit pin 84. The lower end of the limit pin 84 is fixedly connected to a combing plate 81, and the lower surface of the combing plate 81 is fixedly connected to a plurality of combing strips 85. The limit pin 84 slides inside the connecting block 82 to limit the moving direction of the combing plate 81. At this time, the combing strips 85 on the combing plate 81 can be inserted into the position between the bristles 711. The lower side of the combing strip 85 is an arc-shaped structure. The arc-shaped combing strip 85 improves the combing effect on the bristles 711. The internal thread of the connecting block 82 is connected to a drive rod 83, which is internally rotatably connected to the combing plate 81. Rotating the drive rod 83 will drive the combing plate 81 downward.
[0034] like Figure 1 and Figure 5-8As shown, the support structure 9 comprises a rectangular frame 91 fixedly connected to the underside of the first discharge frame 4. Four sliders 92, arranged in pairs, are slidably connected to the inner side of the rectangular frame 91. A fixed block 94 is fixedly connected to the surface of the sliders 92. A positioning pin 95 is slidably connected to the inner side of the fixed block 94. A support rod 93 is fixedly connected to the end of the positioning pin 95. Several tapered rods are fixedly connected to the sidewalls of the support rod 93. The tapered rods are inserted into the bottom of the packaging bag to provide stable support for the bag opening. A row of sockets 98 are defined on the back side of the rectangular frame 91. Second bolts 97 are threadedly connected to the inner sides of the sliders 92. The size of the second bolts 97 matches the size of the sockets 98. By engaging the second bolts 97 with the sockets 98 on the back side of the rectangular frame 91, the spacing between the sliders 92 can be adjusted to accommodate packaging bags of different sizes. A first bolt 96 is threadedly connected to the inner side of the fixed block 94. The first bolt 96 is internally rotatably connected to the support rod 93. The distance between the support rods 93 can be fine-tuned by rotating the first bolt 96 so that the tapered rods are inserted into the bottom of the packaging bag, thereby achieving stable support for the bag opening.
[0035] Working principle: crayfish are poured into the screen frame 3 through the lower hopper 6, and the screen frame 3 performs preliminary size screening on the crayfish. Small-sized crayfish pass through the sieve holes of the screen frame 3 and fall into the inner side of the fixed frame 2, and are discharged through the first discharging frame 4. Large-sized crayfish remain on the screen frame 3 and slide along the inclined surface of the screen frame 3 to the second discharging frame 5 for discharge. When the claws or body of the crayfish are placed on the screen frame 3 and cannot fall off by themselves, the first motor 703 is started, driving the screw rod 704 to rotate, driving the mounting plate 705 to move back and forth horizontally along the guide rail frame 701, and the second motor 706 on the mounting plate 705 drives the brush roller 707 to rotate. The three sets of arc-shaped bristles 711 rotate with the brush roller 707 and contact the surface of the screen frame 3. By setting the bristles 711 with an arc structure, it can be used The side wall of the arc-shaped brush 711 is used to sweep the stuck crayfish into the fixed frame 2 through flexible sweeping, so as to avoid clogging of the screen holes and improve the screening efficiency. Moreover, the brush 711 can realize a simple sweeping and cleaning work on the surface of the crayfish. By setting the first motor 703 to drive the second motor 706 to move, the crayfish in different positions can be scattered, which can effectively avoid the phenomenon of crayfish being retained on the screen frame 3 during the screening process, further improving the screening efficiency of the crayfish. By setting the sweeping structure 7 and utilizing the sweeping method, it is convenient to sweep away the crayfish retained on the inside of the screen frame 3, and can realize a simple sweeping and cleaning work on the surface of the crayfish, thereby improving the performance of the sorting equipment to a certain extent.
[0036] The brush roller 707 is driven to operate by rotating the driving rod 83. The driving rod 83 will drive the combing plate 81 to move downward, wherein the limit pin 84 slides inside the connecting block 82 to limit the moving direction of the combing plate 81. At this time, the combing strips 85 on the combing plate 81 can be inserted into the position between the bristles 711. During the operation of the bristles 711, the arc-shaped combing strips 85 improve the combing effect of the bristles 711, and can effectively avoid the phenomenon that some crayfish are scraped off by the combing plate 81 when the bristles 711 are clamped, thereby further improving the efficiency of sweeping off the crayfish. By setting the combing plate 81 as a structure that can move up and down, the flexibility of using the combing plate 81 is improved. By setting the combing structure 8, it is not only convenient to scrape off the crayfish clamped by the bristles 711, but also convenient to comb the bristles 711, thereby further improving the performance of the sorting equipment.
[0037] Below the first discharging frame 4, the two groups of sliders 92 in the rectangular frame 91 can slide along the rectangular frame 91, and the second bolt 97 cooperates with the socket 98 on the back of the rectangular frame 91 to adjust the spacing of the sliders 92 to adapt to packaging bags of different sizes. The support rods 93 are connected to the fixed block 94 through the positioning pin 95. The first bolt 96 is rotated to fine-tune the distance between the support rods 93 so that the cone rods are inserted into the bottom of the packaging bag. At this time, stable support for the bag opening of the packaging bag can be achieved. By setting up the support structure 9, the stable support for the bag opening of the packaging bag below the first discharging frame 4 and the second discharging frame 5 is facilitated, which facilitates the subsequent bagging of crayfish and further improves the performance of the sorting equipment. The equipment realizes the full process automation of crayfish screening, sweeping, combing and packaging support through the linkage of motor drive and mechanical structure, which solves the problems of material jamming, accumulation and unstable packaging in the traditional screening process and improves the sorting efficiency and stability.
