Automatic splitting and evisceration device of freshwater fish body

Abstract

The invention discloses an automatic splitting and evisceration device of a freshwater fish body, which comprises a conveying belt deformation mechanism and a conveying belt limiting and pinching mechanism that are arranged on a rack, a splitting mechanism and an evisceration and cleaning mechanism that are located below the conveying belt limiting and pinching mechanism and arranged along a longitudinal center line, and a transmission mechanism for supplying power to a conveying belt and the evisceration and cleaning mechanism, wherein the splitting mechanism comprises a fish splitting cutter and an abdominal expanding protection member that are located below a front section of the conveying belt limiting and pinching mechanism; the fish splitting cutter comprises a motor mounted on the rack and a circular fish splitting knife connected with a spindle of the motor; the abdominal expanding protection member comprises a V-shaped abdominal expanding protection plate located above the fish splitting knife; and extending plates on the two sides of the V-shaped abdominal expanding protection plate are movably articulated with a central axis of the fish splitting knife and further connected with the rack through protection springs. The device is simple in structure, high in automation degree, fish body processing efficiency and high in fish yield of the fish body, and fish is high in quality and good in taste.

Description

technical field [0001] The invention relates to a fish body treatment machine, in particular to an automatic dissection and viscera removal device for freshwater fish. Background technique [0002] The process of killing fish is very cumbersome and requires operations such as laparotomy and visceration. In actual production, laparotomy and visceration are mainly performed manually. This production method is inefficient and the product quality standard is difficult to control, especially when dealing with large quantities of fish. When raw fish, the labor intensity of the operator is very high. The machines that appear on the market instead of manual labor are cut open from the abdomen or back, and then the internal organs are washed away with high-pressure water jets or removed with a hook shovel fixed on the frame. For example, 201811041333.3 discloses a fully automatic fish dissection and evisceration device, including a transmission mechanism, a laparotomy mechanism, and...

AI Technical Summary

Problems solved by technology

Although this device can realize automatic dissection and removal of viscera, there are still the following problems: (1) Since the gut of freshwater fish is close to the abdomen, it is easy to cut the gut by cutting the belly of the fish with a knife, which affects the quality of fish meat (2) The inner wall of the abdominal cavity of most freshwater fish is covered with a black film, and the existence of the black film will also affect the taste of the fish. The method of removing the viscera by imitating the comb and dragging to clean the internal organs cannot effectively remove the black film simultaneously; ( 3) Although the fish body is also fixed by clamping, when the fish body enters the pinching device, how to adapt to fish bodies of different sizes and thicknesses, how to form a state that is conducive to clamping, and how to adjust the posture that is useful for subsequent cutting None of the problems have been effectively solved, and there may be problems of low yield of fish meat or incomplete removal of viscera
