Description

Technical Field

[0001] This utility model belongs to the field of crayfish screening, specifically relating to a crayfish diversion and screening device. Background Technology

[0002] Lobster is a high-protein food. The meat of crayfish is tender and easily digestible, making it an excellent food for those who are weak or recovering from illness. The meat also contains abundant elements such as magnesium, zinc, iodine, and selenium. Magnesium plays an important role in regulating heart activity; it can reduce cholesterol levels in the blood, prevent arteriosclerosis, and dilate coronary arteries, thus helping to prevent hypertension and myocardial infarction. As people's living standards improve, the demand for crayfish continues to increase.

[0003] Lobster selection has high requirements, including packaging the lobsters' appearance and sorting them by size. Traditionally, manual sorting is used, but lobsters in the same container are messy and difficult to sort, making it difficult to increase the sorting speed and easily causing lobster legs to be damaged.

Detailed Implementation

[0019] The embodiments of this utility model are further described below with reference to the accompanying drawings.

[0020] Example 1

[0021] like Figures 1 to 4As shown; a crayfish diversion and screening device includes a crayfish dispersing device 1, a screening device 2, and a telescopic belt conveyor.

Connected to the vibrating screen plate 12, the vibrating motor 15 is mounted on the vibrating frame 14. Several downward-sloping spray nozzles 16 and upward-sloping spray nozzles 17 are respectively installed in the dispersion tank 11 and located on the upper and lower sides of the vibrating screen plate 12. Several vertical spray nozzles 18 are installed between adjacent upward-sloping spray nozzles 17. The inclined conveyor 19 is installed in the dispersion tank 11 and cooperates with the vibrating screen plate 12 and the screening device 2. The screening device 2 includes side plates 21, a feeding conveyor 22, a discharging conveyor 23, an arc plate 24, a connecting frame 25, a camera 26, and a shrimp-driving mechanism 27. Several side plates 21 are connected to the connecting frame 25. The feeding conveyor 22, the discharging conveyor 23, and the arc-shaped plate 24 are connected between adjacent side plates 21. The arc-shaped plate 24 is positioned between the feeding conveyor 22 and the discharging conveyor 23. Several cameras 26 are positioned between corresponding adjacent side plates 21 and connected to the connecting frame 25. The shrimp-driving mechanism 27 is connected to the side plate 21 and cooperates with the arc-shaped plate 24. The shrimp-driving mechanism 27 includes a transmission belt 28, an adjusting cylinder 29, a transmission pulley 210, a first hinge rod 211, a friction wheel 212, a rotating shaft 213, a power friction wheel 214, a shrimp-driving device, and a motor. One end of the rotating shaft 213 is connected to the motor, and the other end passes through several side plates. The motor is mounted on the side plate 21. Several power friction wheels 214 are connected to the rotating shaft 213 and are arranged between corresponding adjacent side plates 21 and cooperate with the corresponding friction wheels 212. Several first hinge rods 211 are movably connected to the rotating shaft 213 in the middle. One end of the first hinge rod 211 is movably connected to the friction wheel 212 and the other end is hinged to the adjusting cylinder 29. One end of the adjusting cylinder 29 is hinged to the side plate 21. The transmission pulley 210 is movably connected to the side plate 21 and is connected to the shrimp-driving device through the transmission belt 28. One side of the transmission pulley 210 is connected to a transmission friction wheel that cooperates with the friction wheel 212.The shrimp-driving device includes a fixed column 215, a rotating sleeve 216, a driven pulley 217, a second hinge rod 218, a shrimp-driving rod 219, and a torsion spring. The fixed column 215 is connected between adjacent side plates 21. Two rotating sleeves 216 are fitted onto the fixed column 215. The driven pulley 217 is connected between the two rotating sleeves 216 and is movably connected to the fixed column 215. Several mounting slots 220 are formed on the circumferential surface of the rotating sleeve 216. The second hinge rod 218 is connected to the mounting slots 220. One end of the shrimp-driving rod 219 is movably connected to the second hinge rod 218. The torsion spring is fitted onto the second hinge rod 218 and its two ends are respectively connected to the shrimp-driving rod 219 and the rotating sleeve 216. A mounting frame is installed on the dispersion tank 11, and a monitoring camera is connected to the mounting frame. An extension mesh plate is provided at one end of the vibrating mesh plate 12 near the inclined conveyor 19.

[0022] Lobsters are introduced into the vibrating screen 12 in the dispersion tank 11, and the vibration motor 15 is turned on to make the vibrating screen 12 vibrate, causing the lobsters that are piled up to disperse. The water in the dispersion tank 11 needs to submerge the upward-sloping nozzle 17, so that the dispersed lobsters are impacted by the water discharged from the upward-sloping nozzle 17 and the downward-sloping nozzle 16, causing the submerged lobsters to be impacted and dispersed. At the same time, the vertical nozzle 18 provides a coordinated impact on the lobsters, reducing the possibility of the lobsters tangling together. Then, the lobsters are impacted by the water and conveyed towards the inclined conveyor 19, and finally, the inclined conveyor 19 conveys the lobsters into the screening device 2 for screening. After the lobsters enter the feeding conveyor 22 between the adjacent side plates 21 of the screening device 2, they are conveyed into the arc plate 24 by the feeding conveyor 22. Then, the adjusting cylinder 29 is turned on, and the adjusting cylinder 29 drives one end of the first hinge rod 211 to move, so that the first hinge rod 211 moves to the other end. One end of the friction wheel 212 approaches the transmission pulley 210, making the friction wheel 212 contact the transmission friction wheel. At the same time, the motor is turned on to drive the rotating shaft 213 to rotate. The rotating shaft 213 drives the power friction wheel 214 to rotate. The power friction wheel 214 then drives the friction wheel 212, the transmission friction wheel, and the transmission pulley 210 to rotate in sequence. The transmission pulley 210 drives the transmission pulley 217 to rotate via the transmission belt 28. The transmission pulley 217 drives the rotating sleeve 216 to rotate, causing the shrimp-driving rod 219 to drive the lobster out of the arc plate 24. The lobster enters the discharge conveyor 23 and is then transported out. The telescopic belt conveyor catches the lobster of the corresponding size. The shrimp-driving mechanism 27 needs to use the camera 26 to determine the color and size of the lobster. The torsion spring causes the shrimp-driving rod 219 to have a rotational movement to prevent the lobster from getting stuck between the shrimp-driving rod 219 and the arc plate 24, which would cause the lobster to be squeezed and damaged.
