Description

Technical Field

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

[0002] Fish are the oldest vertebrates and are prone to accumulating heavy metals. Some hybrid offspring with different chromosome numbers are still fertile. They inhabit almost all aquatic environments on Earth, from freshwater lakes and rivers to saltwater seas and oceans.

[0003] Currently, fish processing requires the removal of their internal organs, which is typically done by gutting the fish. This method usually involves manually opening the fish with a knife. However, because fish are prone to flipping, this method is prone to slipping from the hand or being unstable, greatly increasing the risk of injury. Furthermore, manually holding a knife not only increases the risk of accidental injury but also results in low efficiency. Therefore, we propose a fish gutting device to address these problems. Utility Model Content

[0004] The purpose of this invention is to provide a gutting device for fish processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A gutting device for fish processing includes a processing table. A fixing component is connected to one side of the processing table. The fixing component includes two sliding grooves. A sliding rod is connected to the inner sidewall of each sliding groove. A mounting block is slidably connected to the outer surface of each sliding rod. A clamping plate is connected to one side of each mounting block. A telescopic spring is sleeved on the outer surface of each sliding rod. A gutting assembly is connected to one side of the processing table. The gutting assembly includes two bearing seats. A rotating screw is connected to the inner ring of the two bearing seats. A T-shaped fixing seat is threaded to the outer surface of the rotating screw. A servo motor is connected to one end of the rotating screw. A power motor is connected to one side of the T-shaped fixing seat. A cutting wheel is connected to the output end of the power motor. An opening is provided on one side of the processing table.

[0007] In a further embodiment, a mounting bracket is connected to one side of the processing table, a water pipe is connected to one side of the mounting bracket, and a high-pressure water head is connected to one end of the water pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This device is slidably connected to the mounting block via a sliding groove, and the sliding rod is slidably connected to the mounting block. The rebound force of the telescopic spring allows the two clamps to easily and quickly clamp and position fish of different sizes, avoiding the situation where the fish swings and affects the efficiency of gutting.

With the rebound force of the telescopic spring 202, the sliding rod 203 is slidably connected to the mounting block 204, and the mounting block 204 is slidably connected to the sliding groove 201. This allows the fish that needs to be gutted to be pressed directly between the two clamps 205 for fixation. At the same time, stepping on the foot pedal start switch 5 causes the power motor 305 to drive the cutting wheel 306 to rotate, and starts the servo motor 304 to work. Subsequently, the rotation of the servo motor 304 can drive the rotating screw 302 to rotate in the inner ring of the bearing seat 301. With the T-shaped fixing seat 303 threadedly connected to the rotating screw 302, the cutting wheel 306 can be moved to gut the fish. After gutting, the fish can be turned over, and the internal organs can be removed and cleaned using the water pipe 8 and the high-pressure water head 9. The above is the complete usage process of this utility model.
