On the frame 100, the conveyor belt 240 is transmission-connected to the first conveyor wheel 220 and the second conveyor wheel 230, the first support frame 250 is provided with a first channel 251 for the conveyor belt 240 to pass through, the second support frame 260 is located at the front side of the first support frame 250, and the second support frame 260 is provided with a second channel 261 for the conveyor belt 240 to pass through. When the conveyor belt 240 passes through the first channel 251 and the second channel 261 in sequence, the two sides of the conveyor belt 240 are bent upward relative to each other to form a conveying trough 241.

[0042] The thread picking mechanism 300 is located above the conveying trough 241, and the thread picking mechanism 300 includes a first driving member 310, a thread cutter 320, a second driving member 330 and a thread hooking knife 340.

The thread cutter 320 is connected to the power output end of the first driving member 310, and a blade 321 is provided at the end of the thread cutter 320. The thread hooking knife 340 is connected to the power output end of the second driving member 330, and a hook end is provided at the end of the thread hooking knife 340. The first driving member 310 can drive the thread cutter 320 to extend downward into the conveying trough 241, so that the blade 321 cuts off the shrimp intestine at the shrimp tail position, and the second driving member 330 can drive the thread hooking knife 340 to extend downward into the conveying trough 241, so that the hook end hooks the shrimp intestine.

[0043] Based on the shrimp body gutting device with the above technical features, the conveying driving member 210 can drive the conveying belt 240 to transmit between the first conveying wheel 220 and the second conveying wheel 230 to realize the conveying of the shrimp body. Among them, the first channel 251 on the first support frame 250 and the second channel 261 on the second support frame 260 are used to bend the two sides of the conveyor belt 240 upward relative to each other to form a conveying groove 241, so that the shrimp body is kept in a vertical state in the conveying groove 241 for conveying. When the shrimp body to be processed is conveyed to the position below the thread picking mechanism 300, the first driving member 310 can drive the thread cutting knife 320 to extend downward into the conveying groove 241, so that the blade 321 cuts off the shrimp intestine near the shrimp tail. The second driving member 330 can drive the thread hooking knife 340 to extend downward into the conveying groove 241, so that the hook end is inserted into the shrimp back and hooks up the shrimp intestine, so that the shrimp intestine will not remain in the shrimp body, and the damage to the shrimp meat is very small, thereby ensuring the quality of the processed shrimp. It has the advantages of high degree of automation, reduced processing cost, and improved processing efficiency.

[0044] Among them, combined Figure 4 As shown, the shrimp intestine and shrimp tail inside the shrimp body are connected together, so the wire cutting knife 320 is inserted into the 5th section of the shrimp body (close to the shrimp tail) to disconnect the shrimp intestine and the shrimp tail, and then the wire hooking knife 340 is inserted into the 3rd section of the shrimp body and the shrimp intestine is hooked up to remove the entire shrimp intestine from the shrimp body and avoid it from remaining in the shrimp body.

[0045] In this embodiment, if Figures 4 to 5 As shown, the thread cutting knife 320 and the thread hooking knife 340 are both in the shape of strips, which facilitates the thread cutting knife 320 and the thread hooking knife 340 to be inserted into the interior of the shrimp body from top to bottom. On the one hand, it can reduce the resistance when inserting into the shrimp body, and on the other hand, it can reduce the incision caused to the shrimp body, thereby ensuring that the damage to the shrimp meat is small and ensuring the quality of the processed shrimp.

[0046] In this embodiment, if Figure 6 As shown, the blade 321 is in a U-shaped or V-shaped shape with the opening facing downward, and the opening has a certain width, that is, as long as the shrimp intestine enters the opening, it can be cut off, and there is no need to accurately locate the position of the shrimp intestine, which reduces the difficulty of processing. Among them, the first spike portion 322 is provided on both sides of the opening of the blade 321 to facilitate insertion into the shrimp body. The first driving member 310 and the second driving member 330 are both telescopic cylinders.

[0047] In this embodiment, if Figure 7As shown, the hook end includes a first hook rod 341 and a second hook rod 342, the first hook rod 341 has a first hook portion 343 extending obliquely upward at the bottom end, so that a first hook groove 344 is formed between the top surface of the first hook portion 343 and the first hook rod 341, and the second hook rod 342 has a second hook portion 345 extending obliquely upward at the bottom end, so that a second hook groove 346 is formed between the top surface of the second hook portion 345 and the second hook rod 342, the first hook portion 343 and the second hook portion 345 are arranged opposite to each other, that is, the first hook portion 343 and the second hook portion 345 form an entrance, when the shrimp intestine enters the entrance, it can enter the first hook groove 344 or the second hook groove 346, the second driving member 330 can drive the hook line knife 340 to rise, so as to lift the shrimp intestine, wherein the top surface and the bottom surface of the first hook portion 343 and the top surface and the bottom surface of the second hook portion 345 are planes or arc surfaces to avoid cutting or hooking the shrimp intestine.

[0048] Further, the top surface of the first hook portion 343 intersects with the bottom surface of the first hook portion 343 to form a first hook tip 343a, the top surface of the second hook portion 345 intersects with the bottom surface of the second hook portion 345 to form a second hook tip 345a, the first hook tip 343a is located above the second hook groove 346, there is a certain gap between the first hook tip 343a and the second hook rod 342, the second hook tip 345a is arranged toward the bottom surface of the first hook portion 343, there is a certain gap between the second hook tip 345a and the first hook portion 343, that is, the bottom surface of the first hook portion 343 and the bottom surface of the second hook portion 345 are combined to form an "entry"-shaped entrance, and the length of the bottom surface of the first hook portion 343 is greater than the length of the bottom surface of the second hook portion 345. The bottom surface of the first hook portion 343 and the bottom surface of the second hook portion 345 play a guiding role. When the shrimp intestine enters from the entrance, it moves to the top of the second hook groove 346 under the guidance of the bottom surface of the first hook portion 343 or the bottom surface of the second hook portion 345, and is lifted by the second hook groove 346; or if the hooking wire knife 340 is inserted deeper, the shrimp intestine will move to the top of the first hook groove 344, and be lifted by the first hook groove 344. When the hooking wire knife 340 is inserted to a certain depth, the structural design of the hook end can ensure that the shrimp intestine is lifted by the first hook groove 344 or the second hook groove 346, and has the advantages of simple structure and good stability.

[0049] Furthermore, the bottom surface of the first hook portion 343 intersects with the bottom end of the first hook rod 341 to form a second spike portion 347, and the bottom surface of the second hook portion 345 intersects with the bottom end of the second hook rod 342 to form a third spike portion 348. The second spike portion 347 and the third spike portion 348 are both conical, which facilitates the insertion of the hooking knife 340 into the shrimp body from top to bottom, and during the insertion process, the bottom surface of the first hook portion 343 or the bottom surface of the second hook portion 345 can guide the shrimp intestines. Among them, the second spike portion 347 and the third spike portion 348 are flush, and the second spike portion 347 and the third spike portion 348 are located on both sides of the entrance, which can limit the movement of the shrimp intestines between the second spike portion 347 and the third spike portion 348, ensuring that the shrimp intestines can be hooked up.

[0061] The working principle of the shrimp intestine removal device described in this embodiment is as follows: the shrimp tails of the headless shrimps are placed with their backs facing the moving direction of the conveyor belt 240, and the shrimps enter the conveyor trough 241 with their backs facing upwards. The shrimps are squeezed and straightened under the clamping of the conveyor belt 240. When the shrimps pass through the sensory detector, they are detected by the camera, and the control system receives the detection signal and sends a control command to the mobile driving member 610, so that the mounting plate 500 follows the movement of the shrimps along the slide rail 700. At the same time, the control system A control instruction is also sent to the clamping drive 410 to clamp the shrimp body, and the first drive 310 and the second drive 330 are started in sequence, so that the wire cutting knife 320 is inserted into the 5th section of the shrimp body (close to the shrimp tail) to disconnect the shrimp intestine from the shrimp tail. Then the wire hooking knife 340 is inserted into the 3rd section of the shrimp body and hooks up the shrimp intestine. When the hook is raised to a certain height, the intestine sucker 800 is started, and the hooked shrimp intestine is sucked away from the negative suction pipe under the action of negative suction, thereby achieving the result of removing the shrimp intestine.
