Description

Technical Field

[0001] This utility model relates to the field of separation device technology, and in particular to a fish and shrimp separation device. Background Technology

[0002] Fish and shrimp separation refers to the process of distinguishing and separating fish and shrimp during fishing or seafood processing. Fish and shrimp separation can not only improve production efficiency and ensure product quality, but also promote the rational use of resources and reduce ecological damage.

[0003] Existing fish and shrimp separation devices still have some shortcomings in practical use:

[0004] Existing fish and shrimp separation devices mainly rely on fish and shrimp falling onto an upward conveyor. Fish are transported upward by friction, while shrimp slide downward by gravity. Although this method can effectively separate fish and shrimp, it requires separate transfer and sorting of fish and shrimp of different sizes after separation. The two processes cannot be carried out simultaneously, resulting in low separation efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing technologies where fish and shrimp of different sizes need to be transported and sorted separately after separation, and the two processes cannot be carried out simultaneously, resulting in low separation efficiency. Therefore, a fish and shrimp separation device is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fish and shrimp separation device includes a storage box with four legs at the bottom, the storage box being fixedly connected to the four legs. A conveyor belt is located below the storage box, and mounting plates are provided on both sides of the conveyor belt, with the mounting plates being fixedly connected to two legs on the same side. A fish sieving device is provided at one end of the conveyor belt, and a shrimp sieving device is provided at the other end of the conveyor belt. The fish sieving device and the shrimp sieving device have the same structure and are respectively connected to the two ends of the conveyor belt.

[0008] In one possible design, the fish screening device consists of a baffle, a base plate, a guide frame, and multiple rotating shafts. The baffle and the guide frame are fixedly connected to both sides of the base plate, and the multiple rotating shafts are rotatably connected between the guide frame and the baffle, with one end extending to one side of the baffle. One end of each of the multiple rotating shafts is correspondingly and fixedly fitted with a first sprocket. Adjacent first sprockets are connected by a first chain drive. A first drive motor is mounted on one side of the baffle via a frame. One end of the output shaft of the first drive motor and one end of one of the rotating shafts are both fixedly fitted with a synchronous pulley. Two synchronous pulleys are connected by a synchronous belt.

[0009] In one possible design, two drive rollers are rotatably connected between the two mounting plates, and one end of the rotation shaft of one of the drive rollers extends to one side of one of the mounting plates. The two drive rollers are connected by a conveyor belt. A second drive motor is fixedly installed on one side of one of the legs. A second sprocket is fixedly sleeved on one end of the output shaft of the second drive motor and one end of the rotation shaft of one of the drive rollers. The two second sprockets are connected by a second chain.

[0010] In one possible design, both the fish sieve and the shrimp sieve are provided with support frames at their bottoms, and the two first drive motors are respectively fixedly installed on one side of the two support frames.

[0011] In one possible design, the outer walls of multiple shafts are all fixedly wound with threaded strips.

[0012] In one possible design, the guide frame is provided with sorting slots, and multiple rotating shafts extend into the corresponding sorting slots.

[0013] In this application, a mixture of fish and shrimp is poured into a storage box. The fish and shrimp fall onto a conveyor belt through a narrow outlet in the storage box. A second drive motor is activated, and its output shaft drives a second sprocket connected to a second chain drive. The second sprocket drives two drive rollers connected to the conveyor belt, causing the conveyor belt to rotate upwards. The fish are conveyed upwards by the friction of the conveyor belt, while the shrimp, due to lower friction, slide downwards. The fish are conveyed to a fish-screening device, and the shrimp slide onto a shrimp-screening device. Both the shrimp-screening device and the fish-screening device have multiple rotating shafts at their tops, and the outer walls of these shafts are fixed. The spiral strip is wound around the base plate, and the first drive motor is started. The output shaft of the first drive motor drives two sprockets connected by a synchronous belt to rotate. The two adjacent shafts are connected to the two first sprockets by a first chain, thereby driving the shafts to rotate. The distance between the multiple shafts and the base plate gradually decreases from top to bottom. Fish or shrimp slide down from the surface of the base plate. Larger fish or shrimp are blocked by the shafts and pushed into the corresponding conveying groove of the guide rack by the rotation of the shafts and the spiral strip. Smaller fish or shrimp pass between the shafts and the base plate and are pushed by the rotation of the next shaft, achieving a layer-by-layer screening effect.

[0014] Beneficial effects: In this utility model, the fish and shrimp separation device achieves the screening of fish and shrimp of different sizes by means of multiple rotating shafts connected by rotation and the progressive distance between them and the bottom plate. Larger fish and shrimp are pushed into the corresponding conveying trough, while smaller ones continue to be screened by the next screening element, thereby achieving the effect of fine separation.

[0015] In this utility model, a fish and shrimp separation device is provided, which, on the basis of fish and shrimp separation, is equipped with a fish sieve device and a shrimp sieve device, respectively used to screen the separated fish and shrimp by size, which greatly improves the efficiency of fish and shrimp species screening and fish and shrimp size screening.

[0016] This invention offers significant advantages such as efficient separation, multi-stage screening, automated operation, compact structure, and energy conservation and environmental protection, providing strong support for the separation and processing of fish and shrimp and greatly reducing the labor intensity of workers.
