Roller for shelling Euphausia superba

Abstract

The invention relates to a roller for shelling Euphausia superba. The roller has a double-layer structure of a roller inner ring and a roller outer ring, wherein the roller inner ring is fixed on theinner wall of the roller outer ring, both ends of the roller inner ring are respectively and radially distributed on semi-circular notches, a pair of end covers are arranged on both ends of the roller, a pair of bearings are arranged at the end cover positions, the bearings respectively support a left support shaft and a right support shaft, the left support shaft is connected to a motor, the motor is connected to a speed reducer, the speed reducer is connected to an automatic reversing device, and the automatic reversing device is engaged with the inner tooth ring on the roller inner ring soas to drive the roller to rotate bidirectionally alternately. According to the present invention, the roller has the simple structure, and has characteristics of strong expandability and strong adaptability based on the product lines with different output requirements; and the roller can achieve the constant speed ratio and stable transmission, and further has characteristics of equipment operation impact reducing, vibration reducing, noise reducing and energy loss reducing.

Description

technical field [0001] The invention relates to a roller, in particular to a roller for shelling Antarctic krill. Background technique [0002] Antarctic krill not only has a huge amount of biological resources, but also has high value. In addition to producing shrimp meal and extracting shrimp oil, the production of shelled shrimp meat products is another effective means of utilizing Antarctic krill resources. At present, roller extrusion is one of the effective methods for shelling Antarctic krill. Its core is that multiple rollers are arranged side by side, and the shell and meat of krill are separated through the gap and extrusion between the rollers. In order to effectively separate the shell and meat, the large and small rollers need to reciprocate. In the prior art, there is a shelling device specially for Antarctic krill. This device generally realizes the reciprocating motion of the large and small rollers through a crank slider mechanism and gear transmission. Ab...

AI Technical Summary

Problems solved by technology

[0004] 2) Large transmission noise;

[0005] 3) The crank slider reciprocates, resulting in a large combined impact force, severe equipment vibration, and large loss of energy efficiency;

[0006] 4) It is difficult to maintain the equipment. When a part of the above-mentioned device is damaged or the roller is replaced, the above-mentioned device has to be dismantled;

[0007] 5) The above-mentioned device is used in the aquatic industry, where the environment is relatively humid, and the anti-rust and waterproof functions of external motors, reducers and other components are required to be high, which increases the cost of equipment
