A clamping groove 28 is provided on the guide slope 27, and the clamping groove 28 is adapted to the contact head 26; by sliding During the movement of the moving platform 10, the clamping box 24 can be brought into contact with one end of the limit plate 15. Through the slope that one end of the limit plate 15 is inclined to one side, the height of the clamping box 24 can be reduced to the same height as the conveyor belt 6. While the clamping box 24 is lowered, the contact head 26 can be brought into contact with the clamping groove 28. The arc-shaped guide slope 27 with a gradually decreasing height can drive the push rod 25 to move. When the push rod 25 moves, the push block 31 can be driven to slide in the limit groove 30, thereby driving the drive plate 29 to move. When the drive plate 29 moves, the clamping plate 32 can be opened. When the clamping plate 32 contacts the crayfish, the sliding platform 10 moves in the opposite direction, thereby completing the fixing effect on the crayfish.

A plurality of reset springs 42 are arranged between the second deflection plate 41 and the fixed platform 43. A push roller 39 is arranged on the top of the first deflection plate 38, and the push roller 39 is a semicircular structure; a contact plate 40 is arranged on one side of the push roller 39, and the contact plate 40 is an arc-shaped structure deflected to one side; the angle between the first deflection plate 38 and the second deflection plate 41 is sixty degrees; the conveyor belt 6 is rotated to drive the crayfish on the conveyor belt 6 to move at the same time, When the crayfish contacts the first deviation block 33, the crayfish with a lower weight than the standard weight moves along the first deviation block 33 under the guidance of the friction groove 35, and the crayfish can fall into the corresponding collecting groove under the continuous push of the conveyor belt 6. The crayfish with a weight lower than the standard weight can be separated by the cooperation of the first deviation block 33 and the second deviation block 36. At the same time, the crayfish with a weight greater than or equal to the standard weight can push the first deviation block 33 to rotate around the axis of the pushing block 31. At the same time, the first deviation block 33 is reset by the elastic force of the torsion spring 34. The two deviation blocks 36 are in opposite directions, thereby ensuring the center position of the crayfish on the conveyor belt 6 and improving the weight standard of the crayfish; when the weight of the crayfish on the conveyor belt 6 is greater than the standard weight, the second deflection plate 41 can be pressed by the conveyor belt 6, so that the push block 31 rotates along the rotating rod 37, and then drives the first deflection plate 38 to rotate. Through the arc structure of the contact plate 40 deflected to one side, the push roller 39 can push the crayfish on the conveyor belt 6 to leave the conveyor belt 6, thereby completing the screening of crayfish exceeding the standard weight, and further improving the accuracy of the weight standard when packaging crayfish.

[0034] The present solution is specifically as follows: during the movement of the sliding table 10, the clamping box 24 can be brought into contact with one end of the limiting plate 15; one end of the limiting plate 15 is a slope inclined to one side, so that the height of the clamping box 24 can be reduced to the same height as the conveyor belt 6; while the clamping box 24 is lowered, the contact head 26 can be brought into contact with the clamping groove 28; the guide slope 27 is in an arc shape with a gradually decreasing height, so that the push rod 25 can be driven to move; when the push rod 25 moves, the push block 31 can be driven to slide in the limiting groove 30, thereby driving the drive plate 29 to move; when the drive plate 29 moves, the clamping plate 32 can be opened; when the clamping plate 32 is in contact with the small When the crayfish is in contact, the sliding table 10 moves in the opposite direction, thereby completing the fixing effect on the crayfish. The tension spring 21 provides elastic force to ensure stable pressure during the clamping process and avoid damage to the crayfish. The design of the driving plate 29 and the limiting groove 30 ensures the precise sliding and positioning of the pushing block 31 and the clamping plate 32, thereby improving the reliability and efficiency of the clamping operation. The driving source 13 pushes the sliding table 10 to slide on the sliding rail 9. When the sliding table 10 slides, it can drive the first guide rod 17 and the second guide rod 19 to slide along the first limiting groove 44 and the second limiting groove 45 on the guide plate 14 respectively. When the second guide rod 19 moves along the second limiting groove 45 When the track slides, the second limiting groove 45 is an arc-shaped arc deflected to one side, which can change the position of the second guide rod 19, thereby driving the connecting arm 18 to rotate. When the connecting arm 18 rotates, it can drive the rotating convex plate 16 to rotate. When the rotating convex plate 16 rotates, it can drive the clamping assembly to deflect, thereby completing the flipping of the crayfish, thereby separating the liquid in the crayfish, which not only improves the efficiency of flipping and clamping, but also ensures the stability and reliability of the operation, and reduces the impact of the liquid in the crayfish on the subsequent packaging steps; by rotating the conveyor belt 6, the crayfish on the conveyor belt 6 are driven to move at the same time. When the crayfish contacts the first deviation block 33, compared with the standard The crayfish with a lower standard weight moves along the first deviation block 33 under the guidance of the friction groove 35, and under the continuous push of the conveyor belt 6, the crayfish can fall into the corresponding collection groove. The first deviation block 33 cooperates with the second deviation block 36 to separate the crayfish with a weight lower than the standard weight. At the same time, the crayfish with a weight greater than or equal to the standard weight can push the first deviation block 33 to rotate around the axis of the push block 31. At the same time, the first deviation block 33 is reset by the elastic force of the torsion spring 34. The first deviation block 33 and the second deviation block 36 are in opposite directions, thereby ensuring the central position of the crayfish on the conveyor belt 6, thereby improving the weight standard of the crayfish.When the weight of the crayfish on the conveyor belt 6 is greater than the standard weight, the conveyor belt 6 can press the second deflection plate 41, thereby causing the push block 31 to rotate along the rotating rod 37, thereby driving the first deflection plate 38 to rotate, and the arc structure of the contact plate 40 deflecting to one side can cause the push roller 39 to push the crayfish on the conveyor belt 6 off the conveyor belt 6, thereby completing the screening of crayfish that exceed the standard weight, further improving the accuracy of the weight standard when packaging crayfish. ;
