[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-6 The present invention provides a technical solution: a fully automatic live crayfish sorting and grading device, comprising: a calming and cleaning machine 1, and a material distribution frame support leg 2 is installed on the outside of the calming and cleaning machine 1.

[0030] A water cooling mechanism 3 is installed on the outside of the calming and cleaning machine 1, and a separation chain plate 4 is provided in the middle of the calming and cleaning machine 1. The separation chain plate 4 is provided with a lifting block and a brush roller. The lifting block on the separation chain plate 4 will drive a part of the crayfish to move toward the brush roller. When the crayfish are lifted to the brush roller, the brush roller will reject the stacked crayfish, so that at most one crayfish is lifted by each lifting block in the rear section of the lifting, and is sent to the discharge end of the separation module 7 to slide from the material distribution trough of the discharge guide rail 9 to the corresponding area to complete the crayfish distribution work. On both sides of the separation chain plate 4 are the material distribution equipment frames 5, the end outlet of the material distribution equipment frame 5 is connected to the separation module 7, the top power access end of the separation module 7 is connected to the drive motor 8, and a discharge guide rail 9 is installed on one side of the top of the separation module 7. The discharge guide rail 9 is a multi-row guide groove, and a plurality of gates are installed at the lower end of each row of guide grooves. A detection sensor is installed on the guide groove. When multiple crayfish colors and models appear in the identification area, the gate opens and the crayfish in the area are rejected into the calming and cleaning machine to ensure that only one crayfish enters each weighing area of ​​the weighing and sorting machine. An automatic loader 10 is provided at one end of the discharge guide rail 9, and a material distribution device 11 is installed on the automatic loader 10;

[0031] The separation module 7 includes an upward frame 701, a discharge end leg 702, an output end frame 703, a sorter drive 704, an infeed end leg 705 and a nylon chain plate 706. One end of the upward frame 701 is connected to the discharge end leg 702, and the other end of the discharge end leg 702 is connected to the sorter drive 704. The tail end guide rail of the upward frame and the output end frame 703 are installed on the external frame of the sorter drive 704. The other end of the upward frame 701 is connected to the nylon chain plate 706, and the infeed end leg 705 is connected to the outer wall frame of the nylon chain plate 706.

[0032] There is a turning guide rail connected to the upper frame 701 and the discharge end. Connecting the turning guide rail at the discharge end, through the design of the guide rail slide, the panel is converted from a lifting function to a horizontal transmission function.

[0033] The discharge end bracket 702 consists of the discharge end frame side panels and a crossbar. The three-notch design with double waisted holes at the tail end allows for easy disassembly and installation of the drive components and facilitates chain tensioning. The crossbar is connected to the discharge end frame side panels with screws, supporting the frame side panels.

[0034] The sorting machine's drive unit 704 is fixed to the waist-shaped hole of the discharge end frame with bolts and nuts. When the nuts are loosened, the drive unit can slide within the waist-shaped hole. The tail end of the discharge end frame uses ear plates, stiffeners, and extended bolts and nuts to limit the drive unit's position, thereby achieving the drive unit's tensioning function on the nylon chain plate. The reduction motor 1102 is mounted on the welded U-shaped plate 1101 with screws. The driving shaft is synchronized with the hollow shaft of the reduction motor 1102 via a key connection. The driving shaft's nylon sprocket rotates with the driving shaft via a key connection. The nylon sprocket is limited by the shaft sleeve to drive the chain plate movement. The driving shaft and the active bearing are mounted on the U-shaped plate 1101 and together form the driving portion of the sorting device 11.

[0035] The chain plates are made of nylon, and a plurality of lifting blocks are installed at corresponding distances in the nylon chain plate sections for lifting the sedated crayfish. Each lifting block can lift one crayfish.

[0036] The brush roller is installed in the middle of the upper frame 701 and is driven by a servo motor. The brush rotates in the opposite direction to the chain plate. Its function is to reject the live crayfish stacked on the lifting block to ensure that each lifting block only lifts one crayfish.

[0037] The reduction motor 1102 is installed at the tail end of the material distribution device 11. When the reduction motor 1102 is running, the driving shaft rotates, and the driving shaft sprocket drives the chain plate to run, providing power support for the entire material distribution device 11.

[0038] A guide rail corresponding to the dividing trough is placed at the tail end of the dividing device 11. When the crayfish is lifted to the tail end of the rack, it will slide to multiple weighing and grading systems respectively. The dividing device 11 has the same rhythm as the weighing and grading system.

[0039] The water cooling mechanism 3 includes a water tank 301, a condenser pipe 302 and a drain pipe 303. The water tank 301 is provided inside the sedation cleaning machine 1. The condenser pipe 302 is arranged in the water tank 301. One end of the condenser pipe 302 is connected to the drain pipe 303.

[0040] The upper end of the condensation pipe 302 is provided with a separation chain plate 4, and the outlet of the sewage pipe 303 passes through the outer walls of the inner and outer sides of the calming cleaning machine 1;

[0041] A scissor-type reciprocating lift 6 is also installed at the bottom of the calming cleaning machine 1. The scissor-type reciprocating lift 6 includes a lifting component 601, a lower base plate 602 and an upper panel 603. The top of the lifting component 601 is connected to the upper panel 603, and the bottom of the lifting component 601 is connected to the lower base plate 602.

[0042] Discharge ports 13 are installed on both sides of the box-type automatic weighing and sorting machine 12, a box-type hopper 14 is installed on the surface of the box-type automatic weighing and sorting machine 12, a conveyor chain 15 is installed at the bottom of the box-type automatic weighing and sorting machine 14, and the conveyor chain 15 is installed inside the box-type automatic weighing and sorting machine 12. A control console 16 is installed on one side of the box-type automatic weighing and sorting machine 12.

[0043] The material distribution device 11 includes a U-shaped plate 1101, a reduction motor 1102 and a transmission shaft 1103. The reduction motor 1102 is installed on the surface of the U-shaped plate 1101, and the output end of the reduction motor 1102 is connected to the transmission shaft 1103.

[0044] The bottom of the U-shaped plate 1101 is mounted on the surface of one side of the automatic feeder 10;

[0045] There are two groups of box hoppers 14, and the two box hoppers 14 on each group of box hoppers 14 are located directly below the two discharge ports 17 respectively;

[0046] The separation chain plate 4 and the material distribution equipment frame 5 are horizontally installed inside the calming cleaning machine 1 , and the separation module 7 is tiltedly installed between the material distribution equipment frame 5 and the discharge guide rail 9 .

[0047] In summary: Figure 1-6 As shown, when using this fully automatic live crayfish sorting and grading device, before sorting the crayfish, a pre-operation is started, the calming and cleaning machine 1 starts to fill with water, and the water temperature is controlled by the water cooling mechanism 3. The water cooling mechanism 3 consists of a water tank 301, a condenser (external water cooler) 302 and a sewage pipe 303.

[0048] Specifically, before the crayfish enter the sorting system, water is first poured into the water tank 301 to submerge the separation chain plates 4 of the sorting device 11. The condenser (external water chiller) 302 is then activated to cool the water in the water tank 301 to a temperature that allows the crayfish to enter a dormant state upon entering the tank. This reduces the crayfish's metabolic activity, prevents random movement and collision damage, and reduces the risk of crayfish becoming tangled during the sorting process.

[0049] When the temperature of the water in the water tank 301 drops below the corresponding temperature, the dividing device 11 can be turned on to allow the water with a lower temperature at the bottom of the water tank 301 to flow from the tail of the dividing equipment to the upper part of the water tank 301 through the separation chain plate 4. At the same time, the entire dividing system is cooled and moistened to ensure the consistency of the operating environment temperature of the crayfish sorting system.

[0050] After the entire material distribution device 11 is moistened, unsorted crayfish can be poured into the tail of the device. After being soaked in cooling water, the crayfish can be calmed and preliminarily cleaned from horizontal to upward in the middle of the material distribution rack.

[0051] After the live crayfish are separated by the sorting device 11, they fall directly from a chute into the cassette hopper 14 of the automatic cassette weighing and sorting machine 12. This weighing system consists of one or more cassette weighing and sorting units. After the crayfish fall from the feed device into the cassette hopper 14, they are moved along the guide rails by the conveyor chain 15. After being weighed by the load cells, they are sorted and discharged from the corresponding discharge port 13 by the cassette hopper 14 according to the sorting program preset by the control console 16. Crayfish weighing less than the specified weight and other debris are sorted into a waste bin at the end of the sorting line, completing the crayfish sorting process.

[0052] The beat of the box-type automatic weighing and sorting machine 12 is consistent with that of the material sorting device 11. The material sorting device 11 can correspond to multiple automatic weighing systems, thereby speeding up the sorting of crayfish.

[0053] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
