Circular grooves are opened on the surface of the turntable 5, and the circular grooves are equidistantly distributed in a surrounding manner. When in use, the output end of the first motor 13 drives the turntable 5 to rotate, so that multiple groups of crabs enter the circular grooves of the turntable 5. As the turntable 5 rotates, the crabs rotate, so that the crabs can be conveyed in sequence without manual sorting and weighing one by one.

[0032] According to the attached Figure 2 As shown, a fixing plate 7 is fixed to the top of the first conveyor belt 1, and the fixing plate 7 is arranged to be inclined. One side of the fixing plate 7 is fixedly connected to the surface of the first conveyor belt 1, and the other end of the fixing plate 7 is located close to the turntable 5, so that a large number of crabs can be concentrated in the middle of the first conveyor belt 1 and the fixing plate 7. The gap between the first conveyor belt 1 and the fixing plate 7 is adapted to the length of the crabs, so that the crabs can be gathered and collected, and the position of the crab transmission is limited, so that they can smoothly enter the circular groove of the turntable 5.

[0033] According to the attached Figure 3As shown, a first limiting plate 8 and a second limiting plate 11 are fixed to both ends of one side of the first conveyor belt 1, respectively. The first limiting plate 8 and the second limiting plate 11 are symmetrically arranged. Both sides of the first limiting plate 8 and the second limiting plate 11 are fixedly connected to both sides of the first conveyor belt 1 and the second conveyor belt 2, respectively. One side of the first limiting plate 8 and the second limiting plate 11 are located above the second conveyor belt 2. The inner sides of the first limiting plate 8 and the second limiting plate 11 are both arranged in an arc shape, and the diameter of the arc is greater than the diameter of the turntable 5. The first limiting plate 8 is arranged on one side of the turntable 5, and the length of the first limiting plate 8 is greater than the diameter of the turntable 5. diameter, the second limiting plate 11 is arranged on the other side of the surface of the turntable 5, an arc groove is opened on the inner side of the second limiting plate 11, one side of the second limiting plate 11 extends to the middle of the second conveyor belt 2, the length of the second limiting plate 11 is greater than the length of the first limiting plate 8, the first limiting plate 8 and the second limiting plate 11 are respectively arranged on both sides of the surface of the turntable 5, so that the crabs can be stably placed in the circular groove of the turntable 5, reducing the occurrence of crabs falling when the turntable 5 rotates, and guiding the transmission position of the crabs so that the crabs can be conveyed to a suitable position so that the crabs can be weighed in the center.

[0034] According to the attached Figure 2 As shown, a second conveyor belt 2 is installed on the other side of the first limit plate 8 and the second limit plate 11, and a third conveyor belt 3 and a fourth conveyor belt 4 are installed on both sides of the second conveyor belt 2, a weighing sensor 9 is installed in the middle of the second conveyor belt 2, and a transmission sensor 10 is installed on one side of the weighing sensor 9, a second motor 14 is installed on one side of the ball screw 17, and a controller 15 is installed on one side of the second motor 14, the first conveyor belt 1 and the second conveyor belt 2 are close to each other and work in coordination with each other, the weighing sensor 9 is a laser sensor, which can fully measure the crabs on the conveyor belt by emitting a laser beam. Cross-sectional scanning can obtain the outline and height information of the crab by measuring the reflection or scattering of the laser beam. In combination with the speed of the conveyor belt and the frequency of the laser scanning, the volume of the area occupied by the crab on the conveyor belt can be calculated. The transmission sensor 10 transmits the data detected by the weighing sensor 9 to the data terminal, which then records the data and transmits the data to the controller 15 to control the second motor 14. The data terminal classifies the weight into three levels according to the preset value, namely moderate, large and small weight categories, and transmits the data to the second motor 14 and the controller 15.

The weighing sensor 9 does not need to be in direct contact with the crab, avoiding interference and errors caused by contact. The laser scanning imaging technology has high precision and high resolution, and can accurately capture the outline and height information of the crab, which is convenient for real-time scanning and calculation of the weight of the crab, and can meet the needs of fast and continuous weighing.

One side of the slide groove 19 penetrates the arc groove 20 to drive the moving plate 18 to move, thereby realizing effective classification. The moderate ones pass through the middle of the moving plate 18 to continue to be transmitted, the smaller ones are transmitted through the third conveyor belt 3, and the larger ones are transmitted through the fourth conveyor belt 4.

[0037] According to the attached Figure 5 As shown, the movable plate 18 is located in the middle above the second conveyor belt 2, and a gap is left between the bottom end of the movable plate 18 and the top end of the second conveyor belt 2, so that the movable plate 18 and the second conveyor belt 2 can work with each other without being affected, and can also accurately push the crabs to reduce friction and collision.

[0039] Working principle: When in use, put the whole device in a suitable position, and use an external power supply to provide power for the device. First, the crabs are placed in the first conveyor belt 1 for transmission, and gather along the upper surface of the fixed plate 7 to the middle of the fixed plate 7 and the first conveyor belt 1. Following the transmission direction of the first conveyor belt 1 and the rotation of the turntable 5, they are moved to the corresponding circular grooves of the turntable 5 in turn, and then they are successively transmitted to the top of the second conveyor belt 2 with the rotation of the turntable 5, and are weighed by the weighing sensor 9 and transmitted by the transmission sensor 10. Then, the transmission sensor 10 performs a data transmission on the data. The data is analyzed and transmitted to the terminal, and the terminal transmits the analyzed data to the controller 15, so that the second motor 14 rotates. The second motor 14 rotates clockwise, counterclockwise or not according to the instruction, so that the ball screw 17 rotates differently, so that the ring 21 and the connecting rod 16 remain stationary or move left and right. Finally, the connecting rod 16 drives the moving plate 18 to remain stationary or move left and right, and the heavier and lighter crabs are pushed left and right through the moving plate 18 to the fourth conveyor belt 4 and the third conveyor belt 3 for transmission, and the medium-sized crabs continue to be transmitted through the moving plate 18.

[0040] The above is the entire working principle of the present invention.
