A crayfish sorting device

Abstract

The invention discloses a crayfish sorting device, which includes a frame, a driving motor and a screening mechanism. The screening mechanism includes a chain transmission mechanism, a pushing mechanism and an incoming material transmission rail. The chain transmission mechanism includes a driving sprocket, a chain and a driven sprocket , the driving sprocket is connected with the driving motor; the pushing mechanism includes a fixed plate, a hinge shaft, a torsion spring and a push frame, one end of the torsion spring is installed on the fixed plate and the other end is installed on the push frame; The guide groove of the crayfish moving passage, and the concave-convex lines for the tail of the curled crayfish to pass but the head cannot pass are arranged on the incoming material conveying rail; the push frame has a convex part. The present invention adopts a mechanical transmission screening method, completes the action of automatically removing or reversing the crayfish in the guide groove through the cooperation of the convex part and the concave-convex pattern, and adopts the combined mode of chain transmission and guide groove screening, which greatly improves Production efficiency during the screening operation of incoming shrimp head and tail.

Description

technical field [0001] The invention belongs to the field of crayfish processing equipment, and more specifically relates to a crayfish sorting equipment. Background technique [0002] Crayfish belongs to freshwater economic shrimp, and is a high-quality aquatic product in the Yangtze River Basin of my country. It is widely loved by consumers because of its fast growth speed, strong adaptability, and delicious meat. Since the processing capacity of factories is usually measured in tons, a large amount of labor is required for intensive operations. [0003] In the market environment where the demand for shrimp food is booming, the demand for production capacity is increasing, and the corresponding food safety requirements are becoming more and more stringent. The traditional manual production mode can no longer meet the needs of the current shrimp food processing enterprises. Therefore, some existing equipment for processing crayfish has appeared, which can partially replace...

Problems solved by technology

[0003] In the market environment where the demand for shrimp food is booming, the demand for production capacity is increasing, and the corresponding food safety requirements are becoming more and more stringent. The traditional manual production mode can no longer meet the needs of the current shrimp food processing enterprises. Therefore, some equipment for processing crayfish has appeared, which can partially replace some manual processes.

[0004] On the crayfish processing equipment, when the crayfish is picked up by the jig and transferred to the shrimp head and tail separation device to separate the crayfish, all the crayfish need to have the same orientation, so that the separated shrimp can be processed separately. If the posture of a batch of crayfish is too random, the jig must be rotated to adjust the posture every time a crayfish is picked up, and the visual recognition system that cooperates with the jig will also be increased. processing time, which will lead to low work efficiency; and if the crayfish are sorted manually so that the heads and tails of the crayfish have the same orientation, the work intensity of the workers will be high and the work efficiency will be low, which will directly lead to the processing and production process. The output and quality of the crayfish cannot keep up with the needs of development, and the head, pincers and tail of the crayfish may cause personal injury
